COSMETIC PACKAGE FOR DISPENSING A SEMI SOLID COSMETIC PRODUCT

BACKGROUND

Field

[0001]The present generally relates to a cosmetic package for dispensing a semi solid product such as cream or paste.

Description of the Related Art

[0002]Cosmetic packages that dispense products via the rotation of dialers are known in the art. Traditional stick dispensers often have limitations, such as difficulty in spreading the product evenly on the skin. Therefore, there is a need for dispensing semi-solid cosmetic products, particularly stick products, in a softer form, specifically in a ribbon form, to facilitate smooth application. Most known dispensers are top-dialed, which can result in messiness and inconvenience for users. In contrast, a bottom-dialed dispenser offers more efficient holding and cleaner application. Thus, a bottom-dialed dispenser that ensures efficient holding and clean application, unlike the messier top-dialed dispensers, is required.

[0003]The concept of delivering a stick product in a softer form, particularly in ribbon form, is exemplified by KR102279516B1.

[0004]The primary objective of the present disclosure is to provide a cosmetic package that dispenses the product in a softer form, such as a ribbon form, to facilitate smooth application of the cosmetic product.

[0005]Another objective of the present disclosure is to offer a cosmetic package for dispensing semi-solid products that is user-friendly, overcoming the aforementioned problems with a simple and cost-effective construction.

SUMMARY

[0006]Accordingly, there is provided a cosmetic package for storing and dispensing the semi-solid product. The cosmetic package dispenses semi-solid product by dialing a dialer provided a bottom side of the cosmetic package.

[0007]According to the present disclosure, the semi-solid product can be a stick or, optionally, even pasty, according to a preferred embodiment of the present disclosure. In particular, the product can also form a foam or a gel. The cosmetic package includes but not limited to a cosmetic or care product. The cosmetic or care product includes lip gloss, skincare, under-eye cosmetics, pharmaceutical, and like products. Particularly, the cosmetic package is designed to dispense the semi-solid products such as balms, creams and pastes.

[0008]According to an aspect of the present disclosure, the cosmetic package includes a dispensing assembly and a cap that are designed to be fitted together using snap fitment or corresponding threads alternatively. The dispensing assembly comprises an outer container, an inner container, a screw rod assembly, a piston, a piston plug, and a dialer. Optionally, the dispensing assembly may include an inner cover secured to an inner side of the cap.

The outer container has an integrally formed cutter, adjacent each of the discharge slits, extending from on a lower surface of the dispensing surface that enables the product to be dispensed in a particular form dependent on the shape of the cutter. Preferably, the cutter helps dispensing out product in a thin ribbon-like form.

[0010]According to another aspect of the present disclosure, the inner container is configured to house the semi-solid cosmetic product. The inner container is received within the outer container such that upper and lateral sides of the inner container is covered by the outer container.

[0011]According to another aspect of the present disclosure, the screw rod assembly and piston work together to discharge the cosmetic product from the inner container to the dispensing surface of the outer container. Additionally, a dialer is attached to the lower end of the piston rod assembly and to the inner container. The dialer is non-rotatably engaged to a lower end of the screw rod assembly, and rotatably engaged to a lower end portion of the inner container. The dialer can rotate independently of both the outer and inner containers. When the dialer is rotated, the inner and outer containers remain stationary, but the screw rod assembly rotates with the dialer, causing the piston to move upward and push the cosmetic product toward the dispensing surface.

[0012]According to yet another aspect of the present disclosure, the cap includes an upper wall and a circumferential sidewall extending downwardly from a peripheral edge of the upper wall. The upper wall has an exterior upper surface and an interior surface opposite to the exterior surface. An inner surface of the circumferential sidewall includes a peripheral indentation and a multitude of evenly spaced protrusions.

[0013]According to yet another aspect of the present disclosure, the inner cover is housed within and attached to the cap such that when the cap is disengaged from the dispensing assembly the inner cover is also removed along with the cap. The inner cover is configured to cover and abut the dispensing surface of the outer container when the cosmetic package is not in use and the cap is engaged to the dispensing assembly. The inner cover is a circular component that has a bottom wall and a cylindrical sidewall that extends upward from a periphery of the bottom wall enclosing a hollow space. The bottom wall has a top surface and a bottom surface opposing the top surface. At an upper edge of the cylindrical sidewall, a peripheral flange is located that extends radially outward out from the cylindrical sidewall of the inner cover.

[0020]Further, the neck portion of the outer container includes an annular protrusion on an outer surface thereof. The annular protrusion is configured to be received in the peripheral indentation of the cap to removably engage the outer container to the cap. Further, multiple evenly spaced male protrusions are located on an inner surface of the neck portion near a lower end thereof. These male protrusions facilitate the engagement of the outer container with the inner container.

[0021]According to yet another aspect of the present disclosure, the inner container has a cylindrical structure comprising a sidewall having an open upper end an open lower end. The cylindrical shape of the inner container allows for easy insertion and removal from the cylindrical body of the outer container.

[0022]Further, an outer surface of the inner container has locking features that engage with the outer container at the upper end. The locking features on the outer surface of the inner container are designed to securely attach it to the outer container, preventing any leakage or spillage during use.

[0023]The inner container comprises an annular snap protrusion on outer circumference thereof, located near the open upper end of the inner container. As seen in FIG., the annular snap protrusion is configured to be received within an annular snap groove located on an inner circumference of the outer container on the neck portion.

[0024]Furthermore, the outer surface of the inner container includes a first outer annular flange positioned axially beneath the annular snap protrusion. The first outer annular flange includes a plurality of projections uniformly and circumferentially spaced from one another. The plurality of projections of the first outer flange fit snugly within the circumferential spaces between the evenly spaced male protrusions located at the inner peripheral edge of the outer container. A second outer annular flange is located below the first outer annular flange positioned in continuation without any axial gap. The second outer annular flange extends radially outward to a greater distance than the first outer annular flange. Located near a lower portion of the inner container is a third outer annular flange. Additionally, the outer surface of the inner container includes an inverted L-shaped flange, positioned below the third outer annular flange. A sidewall of this inverted L-shaped flange extends downward towards the lower end of the inner container. Further, the sidewall of this inverted L-shaped flange incorporates an annular snap bead on an outer surface thereof for securing the inner container to the dialer. The inner surface of the sidewall the inner container, near the open lower end thereof, incorporates an annular snap groove.

[0025]The inner container can be made of a rigid material such as plastic or glass to ensure stability and durability during use.

[0026]According to yet another aspect of the present disclosure, the screw rod assembly is received in the inner container. The screw rod assembly includes an elongated shape screw rod with threads formed along its outer surface. At a lower end of the screw rod, a support plate is integrally connected, providing vertical stability to the screw rod within the bottom part of the inner container. The support plate, resembling a disc, is secured on the bottom part of the inner container and fits snugly into an annular snap groove located on the inner surface of the bottom part of the inner container, thus securely attaching the screw rod assembly to the inner container while allowing rotational movement between them.

[0027]Further, a cylindrical part extends from a lower surface of the support plate, the cylindrical part extends outside the open lower end of the inner container. Furthermore, multiple ribs extend radially on the lower surface of the support plate surrounding the cylindrical part, the ribs uniformly distributed. The multiple ribs assist in aligning the screw rod with the center of the dialer, ensuring stable positioning and facilitating rotation synchronized with the dialer. The support plate and a screw rod can be separate components or integral parts of the screw rod assembly. In a preferred embodiment, the support plate and the screw rod are integrally formed.

[0028]Additionally, the support plate also serves as a resting base for the piston at an initial stage. The screw rod assembly of the present disclosure can be made of metal or hard plastic.

[0029]According to yet another aspect of the present disclosure, the piston is coupled to the screw rod so that the piston ascends and descends as the screw rod assembly rotates. At this time, the outer surface of the piston contacts the inner diameter of inner container. The cosmetic product is received in the inner container and is accommodated in a space provided at an upper portion of the piston and is pressed when the piston is lifted and lowered.

[0030]Furthermore, the piston has an annular inner wall, an annular outer wall and a plate-shaped transverse annular wall connecting the annular inner wall to the annular outer wall. The annular outer wall is positioned at the outer periphery of the transverse wall, elastically contacting with the inner surface of the inner container at an upper point and a lower point thereof.

[0031]Further, the annular inner wall of the piston has a through hole, and a middle section of the annular inner wall includes screw threads formed in an inner periphery thereof. The annular inner wall allows the screw rod to passed through the through hole. The screw threads of the piston are configured to be connected to threads of the screw rod. Additionally, the annular inner wall accommodates a central plug in the hollow interior thereof at an upper section thereof. More particularly, through hole has an upper half portion and a lower half portion, with the upper half portion is configured to receive and retain the central plug. The central plug is snap fitted into the upper half portion of the through hole.

[0032]According to yet another aspect of the present disclosure, the central plug is a hollow cylindrical body with a through-hole is formed at the center thereof. The central plug includes an open lower end and an open upper end. An inner diameter of the open upper end portion of the central plug has a larger diameter as compared to its inner diameter at lower end portion thereof. An inner periphery of the lower end portion of the central plug is provided with corresponding threads to match with the threads of screw rod. The hollow cylindrical body of central plug has at least one annular bead and an upper flange extending outwardly from an upper edge of the hollow cylindrical body. The upper flange of the central plug rest upon the upper end of the annular inner wall of the piston, and the at least one annular bead snaps into a corresponding annular groove provided on upper inner periphery of the annular inner wall to secure the central plug into the annular inner wall of the piston. The central plug is made of a material having flexibility and elasticity, that makes an intimate contact, preferably airtight contact with the screw rod, such as NBR, silicon or any other material known in the art.

[0033]According to yet another aspect of the present disclosure, the dialer is cylindrically shaped and is connected to the lower end of the inner container, particularly to the inverted L-shaped flange of the inner container. The dialer includes a peripheral wall and a bottom wall. An outer diameter of the peripheral wall is substantially equal to the cylindrical body of the outer container. The bottom wall makes the cosmetic container suitable to rest on a planar surface in an upright position.

[0034]An annular groove is provided at upper end portion of an inner periphery of the peripheral wall of the dialer, which securely fastens onto the annular snap bead located on the outer surface of the inverted L-shaped flange of the inner container. This securing means allows relative rotation between the dialer and the inner container.

[0035]Further, the dialer is provided with four group of protrusions which are located equidistant on the inner surface of the bottom wall of the dialer. The group of protrusions configured to be engaged between the multiple ribs located at lower face of the support plate, assisting in aligning the screw rod and in installing the screw rod in a non-rotatable manner with respect to the dialer. Thus, when the dialer is rotated the screw rod assembly also rotate along with it.

[0036]To use the cosmetic package, the user first removes the cap, the inner cover also gets removed along with the cap. Further, the rotation of the dialer by the user initiates the rotation of the screw rod, which in turn causes the piston to move up along the screw thread of the screw rod towards the dispensing surface. The piston pushes the cosmetic product in the upward direction. The cosmetic product is dispensed out form the discharge slits in a thin, ribbon-like form, along the cutter. At this time, a user can eject only a necessary amount of the cosmetic product in ribbon form from the discharge slits by controlling the rotation of the dialer.

[0037]According to yet another aspect of the present disclosure, when the cosmetic product within the cosmetic package is about to exhaust, as the piston moves upward, it gradually reaches a final stage where the piston comes in intimate contact with a lower face of dispensing surface, unable to move any further.

[0038]The outer container and inner container can be made of but not limited to polymers such as polystyrene, polyvinyl chloride, polyethylene terephthalate or polyurethane, low density polyethylene (LDPE), high-density polyethylene (HDPE) or polypropylene.

The second outer annular flange 406 extends radially outward to a greater distance than the first outer annular flange 402. Located near a lower portion of the inner container 400 is a third outer annular flange 430. Additionally, the outer surface of the inner container 400 includes an inverted L-shaped flange 440, positioned below the third outer annular flange 430. A sidewall 441 of this inverted L-shaped flange 440 extends downward towards the lower end of the inner container 400. Further, the sidewall 441 of this inverted L-shaped flange 440 incorporates an annular snap bead 442 on an outer surface thereof for securing the inner container 400 to the dialer 800. The inner surface of the sidewall 401 the inner container 400, near the open lower end 420 thereof, incorporates an annular snap groove 421.

[0082]The inner container 400 can be made of a rigid material such as plastic or glass to ensure stability and durability during use.

[0083]As seen in FIG. 3, the dispensing assembly 10 further includes a screw rod assembly 700. Referring to FIGS. 8A and 8B, the screw rod assembly 700 is characterized by an elongated shape screw rod 710 with threads 711 formed along its outer surface. At a lower end of the screw rod 710, a support plate 720 is integrally connected, providing vertical stability to the screw rod 710 within the bottom part of the inner container 400.

[0084]The support plate 720, resembling a disc, is secured on the bottom part of the inner container 400 and fits snugly into the annular snap groove 421 located on the inner surface of the bottom part of the inner container 400 (refer FIG. 4), thus securely attaching the screw rod assembly 700 to the inner container 400 while allowing rotational movement, refer FIG. 4. Additionally, referring to FIG. 8B, a cylindrical part 730 extends from a lower surface of the support plate 720, the cylindrical part 730 extends outside the bottom part of the inner container 400. Furthermore, multiple ribs 730 extend radially on the lower surface of the support plate 720 surrounding the cylindrical part 730, the ribs 730 uniformly distributed. The multiple ribs 730 assist in aligning the screw rod 710 with the center of the dialer 800, ensuring stable positioning and facilitating rotation synchronized with the dialer 800. The support plate 720 and a screw rod 710 can be separate components or integral parts of the screw rod assembly 700. In the exemplary embodiment, the support plate 720 and the screw rod 710 are integrally formed.

[0085]Additionally, the support plate 720 also serves as a resting base for the piston 600 at an initial stage. The screw rod assembly 700 of the present disclosure can be made of metal or hard plastic.

[0086]Referring to FIG. 4, the piston 600 is coupled to the screw rod 710 so that the piston 600 ascends and descends as the screw rod assembly 700 rotates. At this time, the outer surface of the piston 600 contacts the inner diameter of inner container 400. The cosmetic product is received in the inner container 400 and is accommodated in a space provided at an upper portion of the piston 600 and is pressed when the piston 600 is lifted and lowered.

[0087]As shown in FIGS. 9A and 9B, the piston 600 has an annular inner wall 610, an annular outer wall 631 and a plate-shaped transverse annular wall 630 connecting the annular inner wall 610 to the annular outer wall 610. The annular outer wall 610 is positioned at the outer periphery of the transverse wall 630, elastically contacting with the inner surface of the inner container 400 at an upper point and a lower point thereof.

[0088]Further referring to FIGS. 9A and 9B, the annular inner wall 610 has a through hole 640, and a middle section of the annular inner wall 610 includes screw threads 641 formed in an inner periphery thereof. The annular inner wall 610 allows the screw rod 710 to passed through the through hole 640, refer FIG. 4. The screw threads 641 of the piston 600 are configured to be connected to threads 711 of the screw rod 710. Additionally, the annular inner wall 610 accommodates a central plug 500 in the hollow interior thereof at an upper section thereof, refer FIG. 4. More particularly, through hole 640 has an upper half portion H1 and a lower half portion H2, with the upper half portion H1 is configured to receive and retain the central plug 500. The central plug 500 is snap fitted into the upper half portion H1 of the through hole 640.

[0089]Further referring to FIGS. 10A and 10B, the central plug 500 is a hollow cylindrical body with a through-hole 510 is formed at the center thereof. The central plug 500 includes an open lower end 502 and an open upper end 501. An inner diameter of the open upper end portion of the central plug 500 has a larger diameter D1 as compared to its inner diameter D2 at lower end portion thereof. An inner periphery of the lower end portion of the central plug 500 is provided with corresponding threads 511 to match with the threads 711 of screw rod 710. The hollow cylindrical body of central plug 500 has at least one annular bead 503 and an upper flange 504 extending outwardly from an upper edge of the hollow cylindrical body. The upper flange 504 of the central plug 700 rest upon the upper end of the annular inner wall 610 of the piston 600, and at least one annular bead 503 snaps into a corresponding annular groove 644 (FIG. 9B) provided on upper inner periphery of the annular inner wall 610 to secure the central plug 500 into the annular inner wall 610 of the piston 600. The central plug 500 is made of a material having flexibility and elasticity, that makes an intimate contact, preferably airtight contact with the screw rod 710, such as NBR, silicon or any other material known in the art.

[0090]Further referring to FIGS. 4, 11A, and 11B, a cylindrical shaped dialer 800 is connected to the lower end of the inner container 400, particularly to the inverted L-shaped flange 440 of the inner container 400, refer FIG. 4. The dialer 800 has a peripheral wall 810 and a bottom wall 820. An outer diameter of the peripheral wall 810 is substantially equal to the cylindrical body 320 of the outer container 300. The bottom wall 810 makes the cosmetic container 100 suitable to rest on a planar surface in an upright position.

[0091]An annular groove 811 is provided at upper end portion of an inner periphery of the peripheral wall 810 of the dialer 800, which securely fastens onto the annular snap bead 442 located on the outer surface of the inverted L-shaped flange 440 of the inner container 400, see FIGS. 7B and 4. This securing means allows relative rotation between the dialer 800 and the inner container 400.

[0092]Further, referring to FIG. 11A, the dialer 800 is provided with four group of protrusions 830 which are located equidistant on an inner surface of the bottom wall 820 of the dialer 800. The group of protrusions 830 configured to be engaged between the multiple ribs 712 located at lower face of the support plate 720, assisting in aligning the screw rod 710 and in installing the screw rod 710 in a non-rotatable manner with respect to the dialer 800. Thus, when the dialer 800 is rotated the screw rod assembly 700 also rotate along with it.

[0093]To use the cosmetic package 100, the user first removes the cap 20, the inner cover 22 also gets removed along with the cap 20. Further, the rotation of the dialer 800 by the user initiates the rotation of the screw rod 710, which in turn causes the piston 600 to move up along the screw thread 711 of the screw rod 710 towards the dispensing surface 310. The piston 600 pushes the cosmetic product in the upward direction. The cosmetic product is dispensed out form the discharge slits 330, along the cutter 350. At this time, a user can eject only a necessary amount of the cosmetic product in ribbon form from the dispensing slits 330 by controlling the rotation of the dialer 800.

[0094]Referring to FIG. 12, when the cosmetic product within the cosmetic package 10 is about to exhaust, as the piston 600 moves upward, it gradually reaches a final stage where the piston 600 comes in intimate contact with a lower face of dispensing surface 310, unable to move any further.

[0095]Overall, the design of the cosmetic package 100 ensures the dispensing of product in ribbon form, while also providing a controlled and a user-friendly experience for dispensing.
