摘要:
A system for manufacturing a two-part fastener may include a fastener-molding housing and an actuating assembly. The fastener-molding housing may include a fastener mold having a first mold section connected to a second mold section through a flash connection mold section. The fastener mold is configured to receive fastener-forming material to form a pre-engaged fastener having a first fastener portion within the first mold section and a second fastener portion within the second mold section. The first fastener portion is temporarily secured to the second fastener portion through a flash connection portion formed within the flash connection mold section. The an actuating assembly includes a stripper plate, a connecting member, and at least one ejection member. The connecting member is configured to securely retain the first fastener portion. The stripper plate is configured to be moved relative to the connecting member in order to drive one of the first or second fastener portions into the other of the first or second fastener portions to form a fully-formed fastener. The ejection member is configured to eject the fully-formed fastener from the actuating assembly.

A sealing mechanism for container opening comprising: a cylindrical opening disposed on a container body; and a cap for sealing the cylindrical opening, wherein the cap comprises: a cap body having a cylindrical shape for covering a side surface of the cylindrical opening, and provided with a thread portion disposed on an inner surface of the cylindrical shape for engaging with a thread portion disposed on an outer surface of the cylindrical opening, and capable of moving up and down while rotating around the side surface of the cylindrical opening; and an upper lid for covering an opened upper end of the cylindrical opening and sealing the cylindrical opening, wherein the cap body and the upper lid are independent of each other so that the cap body can be rotated without rotating the upper lid, and when the cap body rotates around the side surface of the cylindrical opening to move toward the upper end of the cylindrical opening, the cap body slidably abuts on the upper lid, and pushes up the upper lid to open the cylindrical opening.

A moldable material is injected substantially simultaneously into a mold cavity for the outer sleeve formed between an outer sleeve mold and an outer sleeve core in an injection unit and into a mold cavity for the inner sleeve formed between an inner sleeve mold and an inner sleeve core in a clamping unit of a mold. These mold cavities are connected by at least one relatively thin runner to form at least one predetermined breaking point between the rear end of the outer sleeve and the front end of the inner sleeve of a one-part applicator molding. The invention also relates to an apparatus for producing the tampon applicator according to, but not restricted to, the process as described above.
摘要:
An inner sleeve (12) and an outer sleeve (11) of a tampon applicator provided especially for feminine hygiene form a one-part injection moulding in order to simplify production and assembly. The rear end of the outer sleeve (11) and the front end of the inner sleeve (12) are connected by means of a predetermined breaking point (13). The predetermined breaking point (13) is destroyed due to axial pressure, so that the inner sleeve (12) can be pushed into the outer sleeve (11).
摘要:
A tamper evident closure device having a closure with an internally threaded skirt with a groove therein between radially outer and inner skirt portions to receive a tamper evident band having an inwardly extending bead which engages under a transfer ring of a container to hold the tamper evident band down and hence separate it from the closure as the closure is unscrewed from the container. A method of simultaneously stripping the closure and tamper evident band from a common mold core is also disclosed.

A method for producing a package closure having a neck, a cap and an axis (A) includes a) by means of movable jaws and a tool core forming the neck with an outer thread and the cap with an inner thread, wherein an interior of the neck is formed by an outer first tool core part, and wherein an interior of the cap is formed by an inner second tool core part and a third tool core part, the thread of the cap being formed by the third tool core part, b) removing the jaws from the formed package closure, c) axially displacing the second tool core part in relation to the first tool core part and thereby separating the cap and the neck, d) axially displacing the third tool core part in relation to the second tool core part and thereby disengaging the cap from the third tool core part while keeping the second tool core part engaged with the cap, e) displacing the neck axially in relation to the cap and bringing the thread of the cap into engagement with the thread of the neck through an inherent flexibility of the package closure to form a package closure having a cap mounted on the neck, and f) displacing the package closure in relation to the second tool core part to disengage the package closure from the tool core.
摘要:
A hinged product has a first section and a second section. The first section has a post extending transversely across one end thereof. The second section two co-axial apertures therein, each of the apertures having an internal wall. The post extends between and through the apertures to connect the first section to the second section. There is at least one protrusion located on either the post or the internal walls of the apertures. There is at least one rib disposed the other of the internal walls or the post. The rib contacts the protrusion as the second section is rotated relative to the first section and causes resistance to rotation. This resistance allows for a stepped rotation of the two sections relative to one another. The product is integrally molded in one piece via a molding gate that is offset from a parting line of the mold. When the mold is opened, the mold shears off the molding gate to create a two-piece clip.

The reclosable container (1), adapted to reduce the risk of contamination of the substance contained therein, comprises a hollow body (2) provided with a dispensing mouth (15) which can be plugged through respective detachable closure elements (4, 20, 23) which comprise plugs (6, 6b, 6c, 21, 21b, 25) which can be coupled to the mouth (15); the closure elements (4, 20, 23) are monolithic with the container (1); the plugs (6, 6b, 6c, 21, 21b, 25) are located on the closure elements (4, 20, 23) on the side thereof directed towards the mouth (15). The method comprises the formation of the closure elements (4, 20, 23) nonlithically with the container (1); during formation, the plugs (6, 6b, 6c, 21, 21b, 25) are formed on the closure elements (4, 20, 23) on the side of these elements which is directed towards the mouth (15); at the end of the formation, the plugs (6, 6b, 6c, 21, 21b, 25) are made to couple to the mouth (15). The container and method are used in the pharmaceutical, cosmetic, food industries, etcetera.

The invention relates to a process for manufacture of a top 1 intended to be attached on a container or a flexible tube 50 and comprising a neck 3 the opening 7 of which is connected by a tearable ring-shaped part 10 to a cover 20 serving as an impervious stopper prior to breaking of the ring-shaped part and then being able to serve for recapping. The cover 20 is extended by a plate 30 the periphery 31 of which has a common axis of symmetry with the tearable ring-shaped part 10 and is provided with at least three lugs 32. The skirt 40 is open at one end; its inner surface 46 is partially cylindrical, its section following the exact shape of the periphery 31, except for the lugs, of the plate 30, and is provided with at least three cavities 41 intended to accommodate said lugs. The skirt is drawn around the plate 30 to the point of immobilization, brought about by the insertion of the lugs 32 on the plate 30 into the cavities 41 of the skirt 40.
