AN OUTLET ASSEMBLY FOR ARRANGEMENT AT A WALL OPENING IN AN OUTER WALL OF A DISPENSER FOR WEB-SHAPED ABSORBENT MATERIAL

TECHNICAL FIELD

[0001]The disclosure relates to an outlet assembly for arrangement at a wall opening in an outer wall of a dispenser for web-shaped absorbent material. The disclosure further relates to a dispenser comprising an outlet assembly, and to a method for arranging an outlet assembly to an outer wall of a dispenser.

BACKGROUND

[0002]Dispensers for dispensing web-shaped tissue material for wiping or cleaning purposes are widely used. Web-shaped tissue material such as paper tissue material or nonwoven material come in a variety of shapes and sizes. Typically, the web-shaped tissue material may be provided in the form of a folded stack or in the form of a roll.

[0003]For example, for some applications, it is desired to provide the web-shaped tissue material in the form of a centrefeed roll, i.e. a roll where it is intended to feed the web material from the centre of the roll, by pulling the web material in a direction at least partly parallel to the roll centre axis.

[0004]The web shaped absorbent material may for example be perforated web-shaped absorbent material, where perforation lines may be arranged transverse the length of the web to divide the web shaped material into individual products.

[0005]Dispensers for dispensing perforated web-shaped absorbent materials may be provided with a dispensing element, such as a nozzle,

[0006]However, since it may sometimes be desired to provide for one-by-one product dispensing, whereas it is sometimes instead desired to provide for continuous dispensing of the web-shaped absorbent material, i.e., free flow dispensing, different dispensers having different dispensing outlets with e.g. different nozzles may be provided to meet the various needs.

[0007]However, for reasons of efficiency and versatility, there is a desire to use the same basic dispenser with different dispensing outlets. As such, the dispenser may, for example, be used either for one-by-one dispensing or for free flow dispensing, depending on the dispensing outlet used.

[0008]However, to enable easy mounting and replacement of a dispensing outlet of a dispenser, it is required that the dispensing outlet may be arranged to the dispenser in a time efficient manner, while ensuring that the dispensing outlet is properly positioned at and arranged to the dispenser, such that the dispensing function is ensured.

[0009]In view of the above, there is a strive to develop improved technology relating to dispenser outlets, such as a need for an improvement or an alternative when it comes to providing a dispenser with the option of using different dispensing outlets with the same basic dispenser.

SUMMARY

[0010]An object of the disclosure is to provide a solution which fulfils one or more of the above-mentioned needs, and/or which at least provides a suitable alternative.

[0011]According to a first aspect of the disclosure, an outlet assembly according to claim 1 is provided.

[0015]By the provision of an outlet assembly as disclosed herein, an improved outlet assembly is provided which may facilitate attachment and detachment of the outlet assembly to and from a dispenser. This is achieved by the configuration of the first and second parts, which allows the first fastening member to be inserted from the second part to the first part, implying, e.g., a robust and reliable attachment, and/or a fast and simple attachment/detachment procedure for a user. For example, by interconnecting the first and second parts of the outlet assembly as disclosed herein, a secure attachment of the outlet assembly to a dispenser may be achieved in that the second part covers the at least one second protruding portion when the first part and the second part are attached to each other. Thereby, the first part may be prevented from being detached from the dispenser before the second part has been detached from the first part. Accordingly, by way of example, to detach the first part from the dispenser, the corresponding at least one fastening member may be required to be removed after the second part has been detached from the first part. As such, a two-step detachment procedure for the first part may be achieved, thereby mitigating the risk of the first part unintentionally falling off the dispenser when the second part has been removed. In addition, using a first fastening member for attaching the second part to the first part by use of the first fastening bore and the first protruding portion may imply a fast and reliable attachment therebetween, e.g., mitigating the risk of the second part falling off during use.

[0016]Extending in a direction along an axis, such as along the centre axis of the first part, as used herein, may mean to extend in a direction parallel with the axis, or a direction substantially parallel with the axis, such as within a range of +−5 degrees with respect to the axis.

[0017]Optionally, a geometric centre point of the first protruding portion and a geometric centre point of the at least one second protruding portion, as seen in a geometric sectional plane which is perpendicular to the centre axis of the first part, are located with a substantially equal radial distance from the centre axis of the first part. This configuration may imply a reliable attachment of the first part to the dispenser during use, preventing e.g. any unwanted bending moments about the centre axis of the first part. For example, by said configuration, fastening members attached to the first part may be located with substantially the same distance from the centre axis of the first part, thereby preventing e.g. any unwanted bending moments about the centre axis of the first part. It may also imply a simplified configuration of the dispenser, e.g., by using a symmetrical configuration which for example may be beneficial for manufacturing purposes.

[0018]Optionally, the first protruding portion and the at least one second protruding portion are arranged spaced apart from each other in a circumferential direction of the first outlet portion. A technical benefit may include that positioning and/or fixation of the first part to the second part and/or to the dispenser may be further facilitated, e.g., allowing a user to find the right position of the first part more easily with respect to the second part and/or to the dispenser. This may also imply a further reliable attachment to the second part and/or to the dispenser, e.g., reduced risk of unwanted bending moments.

[0019]Optionally, the first part comprises two second protruding portions, thereby together with the first protruding portion forming a set of at least three protruding portions. Two second protruding portions which are covered as disclosed herein may imply a further secure attachment to a dispenser during use, e.g., mitigating the risk of the first part falling off the dispenser when the second part has been removed.

[0020]Optionally, the set of at least three protruding portions are arranged equiangularly from each other in the circumferential direction of the first outlet portion. A technical benefit may include a facilitated positioning of the first part for a user during an attachment procedure, e.g., allowing the first part to be provided in more than one position with respect to the second part and/or to the dispenser.

[0021]Optionally, any one, such as each one, of the first protruding portion and the at least one second protruding portion encloses a fastening bore configured to receive a fastening member, which fastening bore extends in a direction along the centre axis of the first part. For example, the fastening bores may be corresponding fastening bores, such as similar or identical, fastening bores. Thereby, the same type of fastening member may be used for each fastening bore. This may imply a facilitated attachment/detachment procedure for a user, and/or a cost-effective configuration.

[0022]Optionally, the second part further comprises at least one rib element having an extension in a radial direction from the centre axis of the second part, wherein the at least one rib element is configured to attach the second part to the first part and/or to a rib holding portion of the outer wall of the dispenser. A technical benefit may include that a more reliable attachment is achieved, providing an additional attachment to the first part and/or to the outer wall of the dispenser. For example, the at least one rib element may be configured to provide a snap-fit attachment to the first part and/or to the outer wall of the dispenser. As such, by way of example, the at least one rib element may be arranged to flex in a direction along the centre axis of the second part when attaching the second part to the first part and/or to the outer wall of the dispenser, such that an axial biasing force is created which retains the second part to the first part and/or to the outer wall of the dispenser.

[0023]Optionally, the second part comprises two rib elements, such as three rib elements, each rib element having an extension in a radial direction from the centre axis of the second part, and wherein each rib element is configured to attach the second part to the first part and/or to a rib holding portion of the outer wall of the dispenser. A technical benefit may include that a further reliable attachment is achieved, providing a more reliable additional attachment to the first part and/or to the outer wall of the dispenser.

[0024]Optionally, the two rib elements, such as the three rib elements, are arranged spaced apart from each other in in a circumferential direction of the second outlet portion. A technical benefit may include that positioning and/or fixation of the second part to the first part and/or to the dispenser may be further facilitated, e.g., allowing a user to find the right position of the second part more easily with respect to the first part and/or to the dispenser. This may also imply a further reliable attachment to the first part and/or to the dispenser.

[0025]Optionally, the two rib elements, such as the three rib elements, are arranged equiangularly from each other in the circumferential direction of the second outlet portion. A technical benefit may include a facilitated positioning of the second part for a user during an attachment procedure, e.g., allowing the second part to be provided in more than one position with respect to the first part and/or to the dispenser.

[0026]Optionally, the at least one rib element is at least partly located radially inside the first fastening bore. A technical benefit may include that more space for the at least one rib element and the first fastening bore may be made available. This may imply that the at least one rib element can be made larger, thereby providing a more robust rib element. For example, the radial extension of the at least one rib element may be made larger, e.g., resulting in a more robust configuration.

[0027]Optionally, the outlet portion of the first part comprises a radially outer peripheral surface which surrounds an outlet bore of the outlet portion. A technical benefit may include that the radially outer peripheral surface may be used for providing additional support to the second part and/or to the dispenser when the first and second parts are attached to each other. For example, the outlet bore may be cylinder formed, such as with a cylinder shape with a circular base. A technical benefit may include that the cylinder formed outlet for dispensing of web-shaped absorbent material is used to divide the web shaped material into individual products.

[0028]Optionally, when also the second part comprises at least one rib element as disclosed herein, the first part and the second part are configured such that, when the first part and the second part are attached to each other, a radially inner surface of the at least one rib element is supported by the radially outer peripheral surface of the outlet portion. A technical benefit may include that the radially outer peripheral surface and the radially inner surface of the at least one rib element are used for providing additional support between the second part and the first part when the first and second parts are attached to each other. This may imply improved fixation and positioning of the second part to the first part.

[0029]According to a second aspect of the disclosure, a dispenser according to claim 14 is provided.

[0030]Thus, there is provided a dispenser for web-shaped absorbent material comprising an outer wall defining a wall opening extending along an outlet axis through the outer wall, the dispenser further comprising an outlet assembly according to any one of the embodiments of the first aspect of the disclosure. When mounted at the wall opening of the dispenser, with the first and second parts of the outlet assembly attached to each other, a portion of the outer wall surrounding the wall opening of the dispenser is positioned between the first and second parts of the outlet assembly and is firmly held between the first and second parts of the outlet assembly.

[0031]Advantages and effects of the second aspect of the disclosure are largely analogous to the advantages and effects of the first aspect of the disclosure, and vice versa. It shall also be noted that all embodiments of the first aspect of the disclosure are applicable to and combinable with all embodiments of the second aspect of the disclosure, and vice versa.

[0032]Optionally, the outer wall further defines a first auxiliary opening having an extension in a direction along the outlet axis through the outer wall and being located radially outside the wall opening, wherein the dispenser is configured such that, when the first part and the second part are attached to each other by providing the first part from a first side of the outer wall and by providing the second part from a second opposite side of the outer wall, the first protruding portion and the first fastening bore are aligned with the first auxiliary opening.

[0033]Optionally, the outer wall further defines at least one second auxiliary opening having an extension in a direction along the outlet axis through the outer wall and being located radially outside the wall opening, wherein the dispenser is configured such that, when the first part and the second part are attached to each other by providing the first protruding portion from a first side of the outer wall and by providing the second part from a second opposite side of the outer wall, the at least one second auxiliary opening is aligned with the at least one second protruding portion, allowing insertion of a corresponding at least one fastening member from the second opposite side through the at least one second auxiliary opening and into the at least one second protruding portion. A technical benefit may include that the first part is separately attached to the dispenser and to the second part, respectively, by use of respective fastening members. As such, a more secure attachment of the first part may be achieved, e.g., mitigating the risk of the first part falling off the dispenser when the second part has been removed.

[0034]Optionally, when also the second part comprises at least one rib element as disclosed herein, the outer wall comprises a rib holding portion and the at least one rib element and the rib holding portion are configured such that the second part is attachable to the rib holding portion by rotating the second part about the centre axis of the second part. For example, the at least one rib element and the rib holding portion may be configured to achieve a snap fit connection therebetween, e.g., such that an axial biasing force is created which retains the second part to the outer wall of the dispenser. A technical benefit may include that a further secure attachment of the second part is achieved, by use of two attachment interfaces, i.e., by use of the first fastening member and by the attachment provided by the at least one rib element and the rib holding portion.

[0035]Optionally, the at least one rib element and the rib holding portion are configured such that an attachment therebetween is achieved by rotating the second part 5-20 degrees about the centre axis, such as 8-15 degrees, for example substantially 10 degrees. A technical benefit may include that only a limited amount of rotation may be required by a user for achieving the attachment.

[0036]According to a third aspect of the disclosure, a method according to claim 19 is provided.

[0042]Advantages and effects of the third aspect of the disclosure are largely analogous to the advantages and effects of the first and second aspects of the disclosure, and vice versa. It shall also be noted that all embodiments of the first and second aspects of the disclosure are applicable to and combinable with all embodiments of the third aspect of the disclosure, and vice versa. For example, by the method, a facilitated attachment procedure for a user may be achieved, which also provides a reliable and robust attachment to the outer wall of the dispenser.

[0043]The actions of the method may not necessarily be performed in the order as disclosed herein. In addition, some actions may be performed simultaneously, or at least partly simultaneously. For example, moving of the first and second parts may be performed in any order, simultaneously, or at least partly simultaneously. However, attaching the first part to the outer wall is performed before attaching the second part to the first part and the outer wall.

[0044]Inserting the first fastening member from the second part to the first part as disclosed herein may imply a safer configuration, avoiding unwanted removal of the outlet assembly from the first side of the outer wall, which first side may be an outer side of the dispenser.

[0047]Further advantages and advantageous features of the disclosure are disclosed in the following description and in the dependent claims.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS OF THE INVENTION

[0057]FIG. 1 depicts a non-assembled outlet assembly 1 in exploded view according to an example of the present disclosure. FIG. 1 also depicts a portion of an outer wall 30 of a dispenser 40 for web-shaped absorbent material. More specifically, an outlet assembly 1 for arrangement at a wall opening 31 in an outer wall 30 of a dispenser 40 for web-shaped absorbent material is shown. By way of example, the outlet assembly 1 may be denoted a nozzle. The outlet assembly 1 is for example adapted to ensure that web shaped absorbent material is separated, such as along perforation lines of the web shaped absorbent material, when dispensed. As such, the dispenser 40 may provide for one-by-one product dispensing of individual products. Additionally, or alternatively, the outlet assembly 1 may provide for continuous dispensing.

[0061]The first part 10 comprises a first protruding portion 14 extending in a direction along the centre axis X1 of the first part 10 which is configured to receive and hold a first fastening member 50. The second part 20 comprises a first fastening bore 24 extending in a direction along the centre axis X2 of the second part 20. The first fastening bore 24 is configured to receive the first fastening member 50.

[0062]The first part 10 and the second part 20 are configured to be attached to each other by providing the first part 10 such that the first protruding portion 14 faces the second part 20 and by providing the second part 20 such that the first fastening bore 24 is aligned with the first protruding portion 14 to allow insertion of the first fastening member 50 from the second part 20 to the first part 10, and such that, when the first part 10 and the second part 20 are attached to each other, the first outlet portion 12 and the second outlet portion 22 form the outlet for dispensing of the web-shaped absorbent material from the dispenser 40 through the wall opening 31 in a direction along an outlet axis X.

[0063]The first part 10 further comprises at least one second protruding portion 16, 16′ extending in a direction along the centre axis X1 of the first part 10 and being configured to receive and hold a corresponding at least one fastening member 60, 60′. In the example shown in FIG. 1, there are two second protruding portions 16, 16′. It shall however be noted that there may be fewer, i.e. one, or more second protruding portions.

[0064]The second part 20 is configured such that, when the first part 10 and the second part 20 are attached to each other, the second part 20 covers the at least one second protruding portion 16, 16′. By covering the at least one second protruding portion as used herein is meant that the at least one second protruding portion is not accessible by a user when the second part is attached to the first part.

[0065]For example, as e.g., shown in FIG. 1, a geometric centre point of the first protruding portion 14 and a geometric centre point of the at least one second protruding portion 16, 16′, as seen in a geometric sectional plane which is perpendicular to the centre axis X1 of the first part 10, may be located with a substantially equal radial distance from the centre axis X1 of the first part 10.

[0066]For example, as also shown in e.g., FIG. 1, the first protruding portion 14 and the at least one second protruding portion 16, 16′ may be arranged spaced apart from each other in a circumferential direction of the first outlet portion 12.

[0067]As shown in e.g., FIG. 1, the first part 10 may comprise two second protruding portions 16, 16′, thereby together with the first protruding portion 14 forming a set of at least three protruding portions 14, 16, 16′. For example, the set of at least three protruding portions 14, 16, 16′ may as shown be arranged equiangularly from each other in the circumferential direction of the first outlet portion 12. It may be preferred to provide more than one location for attachments between the first and second parts 10, 20, such as the three attachment locations shown in FIG. 1. By providing more than one attachment location, stability of the attachment between the first and second parts 10, 20 may be improved, in particular if the attachment locations are evenly distributed around the periphery of the first and second outlet portions 12, 22. An even distribution of the attachment locations may also provide the benefit that there are more than one way of attaching the first and second parts of the outlet assembly 1 to each other, which contributes to making mounting of the outlet assembly 1 to the dispenser 40 quick and easy.

[0068]For example, as also shown in e.g., FIG. 1, any one, such as each one, of the first protruding portion 14 and the at least one second protruding portion 16, 16′ may enclose a fastening bore configured to receive a fastening member, which fastening bore extends in a direction along the centre axis X1 of the first part 10. As shown, the fastening members as disclosed herein may be screws with threads. Additionally, or alternatively, the fastening members may be rivets, plugs, or any other elongated fastening member.

[0069]The first protruding portion 14 and the at least one second protruding portion 16, 16′ may for example be cylinder formed protruding portions with fastening bores. As a yet further example, and as depicted in e.g., FIG. 1, the first protruding portion 14 and the at least one second protruding portion 16, 16′ may be of identical shape.

[0070]The second part 20 may as further shown in e.g., FIG. 1 further comprise at least one rib element 26 having an extension in a radial direction from the centre axis X2 of the second part 20. The at least one rib element 26 is configured to attach the second part 20 to the first part 10 and/or to a rib holding portion 34 of the outer wall 30 of the dispenser 40. The possible attachment to a rib holding portion 34 will be further described in the below. A radial direction as used herein is a direction which intersects the respective axis which it refers to and which also is perpendicular to the respective axis.

[0071]For example, as shown in e.g., FIG. 1, the second part 20 may comprises at least two rib elements 26. In FIG. 1, there are three rib elements 26. Each rib element 26 has an extension in a radial direction from the centre axis X2 of the second part 20, and each rib element 26 is configured to attach the second part 20 to the first part 10 and/or to a rib holding portion 43 of the outer wall 30 of the dispenser 40.

[0072]For example, as further shown in FIG. 1, the two rib elements 26, such as the shown three rib elements 26, may be arranged spaced apart from each other in in a circumferential direction of the second outlet portion 22. By way of example, and as shown in e.g. FIG. 1, the two rib elements 26, in this example the three rib elements 26, may be arranged equiangularly from each other in the circumferential direction of the second outlet portion 22.

[0073]For example, as further shown in e.g. FIG. 1, the at least one rib element 26 may be at least partly located radially inside the first fastening bore 24. In the example shown in e.g. FIG. 1, the at least one rib element 26 is completely located radially inside the first fastening bore 24. Thereby it may be avoided that a fastening member in the first fastening bore 24 interferes with the at least one rib element 26.

[0074]FIG. 2 shows an example of an outlet assembly 1 in perspective view when un-assembled. The outlet assembly 1 in FIG. 2 may for example correspond to the outlet assembly 1 shown in FIG. 1. For example, as shown in e.g. FIGS. 1 and 2, the outlet portion 12 of the first part 10 may comprise a radially outer peripheral surface 18 which surrounds an outlet bore 120 of the outlet portion 12. Thereby, by way of example, and as shown in e.g. FIGS. 1 and 2, the first part 10 and the second part 20 may be configured such that, when the first part 10 and the second part 20 are attached to each other, a radially inner surface 262 of the at least one rib element 26 is supported by the radially outer peripheral surface 18 of the outlet portion 12.

[0075]FIGS. 3a-d show an outlet assembly 1 and an outlet portion of a dispenser 40 according to examples of the disclosure. FIGS. 3a-d also depicts an example of a method as disclosed herein.

[0076]More specifically, a dispenser 40 for web-shaped absorbent material is shown which comprises an outer wall 30 defining a wall opening 31 extending along an outlet axis X through the outer wall 30. The dispenser 40 further comprises an outlet assembly 1 according to any one of the embodiments of the first aspect of the disclosure. As may be gleaned, the centre axis X1 of the first part 10 and the centre axis X2 of the second part 20 are aligned with the outlet axis X when the first and second parts 10, 20 are attached to each other.

[0077]For example, as may be gleaned in FIGS. 3a-d, the outer wall 30 of the dispenser 40 may further define a first auxiliary opening 32 having an extension in a direction X0 along the outlet axis X through the outer wall 30 and which is located radially outside the wall opening 31. The dispenser 40 may be configured such that, when the first part 10 and the second part 20 are attached to each other by providing the first part 10 from a first side A1 of the outer wall 30 and by providing the second part 20 from a second opposite side A2 of the outer wall 30, the first protruding portion 14 and the first fastening bore 24 are aligned with the first auxiliary opening 32.

[0078]As a yet further example, which is depicted in e.g. FIGS. 3a-b and in FIG. 1, the outer wall 30 may further define at least one second auxiliary opening 33, 33′ having an extension in a direction along the outlet axis X through the outer wall 30 and which is located radially outside the wall opening 31. The dispenser 40 may be configured such that, when the first part 10 and the second part 20 are attached to each other by providing the first protruding portion 14 from the first side A1 of the outer wall 30 and by providing the second part 20 from the second opposite side A2 of the outer wall 30, the at least one second auxiliary opening 33, 33′ is aligned with the at least one second protruding portion 16, 16′, allowing insertion of a corresponding at least one fastening member 60, 60′ from the second opposite side A2 through the at least one second auxiliary opening 33, 33′ and into the at least one second protruding portion 16, 16′. In the shown examples there are two such second protruding portions 16, 16′ and two such second auxiliary openings 33, 33′. It shall however be noted that there may be more or fewer of such corresponding portions and openings.

[0079]As may be gleaned from FIGS. 3b-d, the second outlet portion 22 of the second part 20 may be formed with a tapering shape which tapers in the direction towards the first part 10 when the second part 20 is attached thereto. For example, as depicted, the second outlet portion 22 may have a funnel shape which tapers towards the first part 10 when the second part 20 is attached thereto, thereby facilitating web-shaped absorbent material to be dispensed from the dispenser 40.

[0080]FIGS. 4a-b show an outlet assembly 1 and an outlet portion of a dispenser 40 according to examples of the disclosure. More specifically, perspective views of the first side A1 of the outer wall 30 is shown.

[0081]For example, as shown in e.g., FIGS. 3a-b and 4a-b, the outer wall 30 may comprise a rib holding portion 34. The at least one rib element 26 and the rib holding portion 34 may as shown be configured such that the second part 20 is attachable to the rib holding portion 34 by rotating the second part 20 about the centre axis X2 of the second part 20. This is also depicted in FIGS. 3c-d, which show perspective views of the second opposite side A2 of the outer wall 30. More specifically, in the shown example, the second part 20 is attachable to the rib holding portion 34 by rotating the second part 20 in a counter-clockwise direction about the centre axis X2 of the second part 20. FIGS. 3c and 4a show a first state before the second part 20 has been rotated and FIGS. 3d and 4b show a second state after the second part 20 has been rotated, i.e. in the second state the second part 20 is attached to the outer wall 30. Also, in the second state the first fastening bore 24 is aligned with the first protruding portion 14 to allow insertion of the first fastening member 50 from the second part 20 to the first part 10 via the first auxiliary opening 32. Accordingly, releasing the second part 20 from the outer wall requires a rotation, such as in the opposite direction, in this example in a clockwise direction about the centre axes X, X2. It shall be noted that the rotation directions may be the opposite to what is shown, i.e., the second part 20 may additionally or alternatively be attached by a clockwise rotation and released by a counter-clockwise rotation. For example, the configuration may as shown be such that it allows the second part 20 to be attached and/or released by rotating the second part 20 in any direction about the centre axis X2. This implies a facilitated attachment/detachment procedure for a user.

[0082]For example, the at least one rib element 26 and the rib holding portion 34 may be configured such that an attachment therebetween is achieved by rotating the second part 5-20 degrees about the centre axis X2, such as 8-15 degrees, for example substantially 10 degrees. Accordingly, by way of example, this rotation may be in any direction.

[0083]For example, as may be gleaned in FIGS. 4a-b, the rib holding portion 34 may be a portion of the outer wall 30 for forming any one, such as each one, of the at least one second auxiliary opening 33, 33′ and the first auxiliary opening 32. The portion 34 may as shown be a bottom portion for forming the respective opening of the outer wall 30.

[0084]For example, the at least one rib element 26 may be arranged to flex in a direction along the centre axis X2 of the second part 20 when attaching the second part 20 to the first part 10 and/or to the outer wall 30 of the dispenser 40, such that an axial biasing force is created which retains the second part 20 to the first part 10 and/or to the outer wall 30 of the dispenser 40.

[0085]The disclosure further relates to a method for arranging an outlet assembly 1 as disclosed herein to an outer wall 30 of a dispenser 40 for web-shaped absorbent material. The outer wall 30 defines a wall opening 31 extending along an outlet axis X through the outer wall 30.

[0090]By way of example, and as shown, the first auxiliary opening 32 and the at least one second auxiliary opening 33, 33′ may be identical in shape. Additionally, or alternatively, as shown, the first auxiliary opening 32 and the at least one second auxiliary opening 33, 33′ may be provided equiangularly from each other about the centre axis X.
