A manufacturing method includes an injection molding process of injection-molding a preform having a two-layer structure including an outer layer preform and an inner layer preform, and a blow molding process of blow molding the preform to mold a delamination container made of resin. The injection molding process includes an outer layer molding process of filling an outer layer injection mold with PET (outer layer resin material) to mold the outer layer preform and molding a thin film portion in a part of the outer layer preform, and an inner layer molding process of injecting PP (inner layer resin material) toward the thin film portion to break the thin film portion and filling an inner layer injection mold with PP having a temperature lower than a melting point of PET via the broken thin film portion to mold the inner layer preform.

The invention relates to a dispenser container consisting of an outer container and an inner container for receiving a fluid, wherein the outer container and the inner container are formed from blow-moulded plastics, which do not form an integral connection with one another, and wherein a first plastic from which the inner container is formed has a higher elasticity than a second plastic from which the outer container is formed, such that the inner container is deformable, and wherein the outer container has at least one pressure compensation opening for pressure compensation in the region between the outer container and the inner container, wherein the inner container has a first outlet region and the outer container has a second outlet region, wherein the first outlet region can be shifted relative to the second outlet region in an outlet direction.

A method of manufacturing a surgical instrument or prosthesis and an injection moulded surgical instrument or prosthesis are described. A first material is injected into a first mould to form an interim component. A second material is injected into a second mould containing at least part of the interim component to form the surgical instrument or prosthesis such that portions of the first and second materials are exposed at the external surface of the surgical instrument or prosthesis. The first and second materials are visually distinct such that at least one exposed portion of the first or second material adjacent to an exposed portion of the other material forms a marking which is visible to a user.

A two-component piston for a cartridge includes a piston cover and a piston body. The piston cover has a radially extending attachment portion, a rear side and a front side. The piston body includes a front side and a rear side. The rear side of the piston cover is arranged adjacent to at least a part of the front side of the piston body and includes a valve member configured and arranged to be received within the piston body and to extend into the piston body towards the rear side of the piston body. The piston cover moves relative to the piston body upon actuation of the valve member, and the piston cover is non-releasably connected to the piston body by a part of the piston body being overmolded to the radially extending portion of the attachment portion of the piston cover.

The invention relates to a watertight closing device (100, 200) for an aseptic container, comprising an external shell (10, 210) made up of a first protecting material, a nucleus (20, 220) made up of a second material suitable for being punched, and a tab (11, 211) equipped with a first free end (12, 212) and with a second end (13, 213) connected to the shell (10, 210). The nucleus (20, 220) has a protruding element (21, 221) placed in correspondence with the connection area (14, 214), so that the protruding element (21, 221) is directly connected to the second end (13, 213) of the tab (11, 211).

The invention relates to a dispenser container consisting of an outer container and an inner container for receiving a fluid, wherein the outer container and the inner container are formed from blow-moulded plastics, which do not form an integral connection with one another, and wherein a first plastic from which the inner container is formed has a higher elasticity than a second plastic from which the outer container is formed, such that the inner container is deformable, and wherein the outer container has at least one pressure compensation opening for pressure compensation in the region between the outer container and the inner container, wherein the inner container has a first outlet region and the outer container has a second outlet region, wherein the first outlet region can be shifted relative to the second outlet region in an outlet direction.

Sports boot element of which the wall includes at least two different plastics materials (15, 16), the wall having (i) a first zone (11) including the two different plastics materials within its thickness, the first plastics material (15) forming two layers of the wall constituting the internal and external faces of the said wall, and the second plastics material (16) being interposed between the two layers of the first plastics material (15), and (ii) a second zone (13) including only the second plastics material (16).

What is presented is a method of forming a closure with a sealing gasket in an injection molding machine that has a center rotating cube. The center rotating cube comprises a plurality of mold back halves each comprising cores and a thread unscrewing mechanism. Each core is shaped to form a closure that has a thread and an anti-rotation feature. The method comprises the steps of forming a closure with a through hole, rotating the core to create a gap between the formed closure and the core, and injecting a compressible material through the through hole and into the gap to form a sealing gasket.

A grip body of a body care article, such as toothbrush, includes a grip part, a neck part, and a head part. The grip body includes a first and a second material component of a thermoplastic plastic. Manufacturing of the grip body is performed via an injection moulding tool with at least one tool cavity, and the grip body including a first, second, and third material component of a first, second, and third thermoplastic material, respectively.

The invention relates to a method for producing a liquid con-tainer (2) for a motor vehicle, which is assembled from at least two shells (4, 6). Furthermore, the invention relates to a liquid container (2) for a motor vehicle.
