A method for blow molding a container having a fiber-based shell ( 20 ) is disclosed. The method comprises the steps of providing a fiber-based shell ( 20 ) introducing a preform ( 30 ) into the fiber-based shell ( 20 ) in order to produce a semi-finished product ( 60 ) gripping the semi-finished product ( 60 ) by means of a gripper ( 40 ) transferring the semi-finished product ( 60 ) into a blow molding tool ( 50 ) and blowing the container. The gripper ( 40 ) presses an inner wall ( 21 ) of the fiber-based shell ( 20 ) onto an outer surface ( 31 ) of the preform ( 30 ).

The invention relates to a method for recycling polyolefin containers, comprising container sorting, intensive wash with comminution of the containers to form flakes, friction wash and density separation, a cleaning step, flake sorting, extrusion and granulation of the cleaned flakes. The cleaning step comprises a percolation of the flakes with cold sodium hydroxide solution at a temperature of <60° C., and a first deodorization of the flakes with steam carried out subsequently to the cleaning.

A mold body ( 10 ) for a blow mold ( 1 ). The mold body ( 10 ) has a bottom region ( 14 ), a shoulder region ( 13 ), a central region ( 15 ) and a separating plane ( 12 ). At least one mold cavity ( 11 ) has an inner wall ( 111 ) situated in the mold body ( 10 ). At least one temperature control channel ( 30 ) is arranged in the mold body ( 10 ). The at least one temperature control channel ( 30 ) is situated and/or positioned in the mold body ( 10 ) in such a way as to remove more heat from or supply more heat to a first region ( 112 ) of the inner wall ( 111 ) than a second region ( 113 ) of the inner wall ( 111 ) that is adjacent to the first region ( 112 ).

The invention relates to a closure cap for closing the pour opening of a container, comprising: a cylindrical threaded part having an open edge, a first cylindrical casing, and an internal thread formed on the inside of the casing which can cooperate with an external thread of a spout delimiting the pour opening, a security ring designed to be retained on a projection molded onto the spout, and a plurality of security webs releasably connecting the security ring to the open edge. A web section has a greater thickness than the remaining security ring. A first or second latching lug protrudes at the open edge, and a gap is formed between the first and the second latching lugs, and a holding web is formed on the web section and projects into the gap in the closure position.

The invention relates to a container closure ( 100 ) having a base body ( 20 ) for fastening to a container. A discharge opening ( 21 ) and a refill opening ( 22 ) are arranged in the base body ( 20 ). The refill opening ( 23 ) is closed by means of a plug ( 30 ).

A sealing film for sealing off a container opening, and a container comprising a sealing film. The sealing film comprises a carrier film and a cover film. Between the carrier film and the cover film is arranged a binding layer for connecting the carrier film to the cover film and having a melting point of less than 120° C.

A method for recycling color-mixed polyolefin containers to produce PCR (Post Consumer Recycled) granules includes the following steps: color sorting the containers, comminuting the containers into flakes, first washing step to remove labels from the flakes by using water at a temperature T1, drying the flakes and labels, separating the dried flakes from the dried labels, second washing step to hot wash the flakes by using an alkaline liquid at a temperature T2>80° C. to remove printing ink from the flakes, drying the flakes, sorting the flakes to remove color contamination and foreign polymers, degassing and granulating the flakes in an extruder, decontaminating the granules and making the granules available for further use. The first washing step is carried out without cleaning additives at a temperature T1 between 60° C. and 80° C. while thermal energy is supplied.

A hinged closure which is molded from plastic and includes a cap which is fastenable to a neck of a container and which has a casing, a cover plate adjoining the casing, a retaining skirt protruding from the inner side of the cover plate, and a dispensing opening provided on the cover plate; and a hinged lid operatively coupled to the cap by a joint and having a sealing nipple on its inner side, which hinged lid is pivotable by means of the joint between a closure and an open position and snaps into place in both the positions. The hinged lid, the joint, the retaining skirt, and at least a first part of the cover plate are injection-molded from a first plastic. At least the casing is injection-molded from a second plastic, and the first and the second plastics are integrally bonded together at their transition.

The invention relates to a fiber-based container comprising a first layer made of compressed pulp, which forms a dimensionally stable sleeve and encloses an interior. The sleeve is at least partially coated with a second layer made of a partially crystalline polyester, and the partially crystalline polyester is applied in the form of a fluid or powder.

A purification method for producing a polyolefin (PO) regenerate (r), including (a) mixing superficially cleaned PO waste (p), referred to as raw polymer (p), with solvent and dissolving the raw polymer (p) in the solvent, (b) recovering the purified polymer from the solvent, (c) preparing the solvent, (d) returning the solvent to step (a), (e) separating residues (e 1 , e 2 ), and (f) extruding the purified PO regenerate (r) to form pellets (r). Step (c) is carried out using at least one membrane filter (c 1 ).
