摘要:
A retortable container (10) is formed with an opening defined by a projecting rim (26). The rim includes an external surface and securing structure formed thereon. A flexible membrane (14) is sealed to the rim and closes the opening. A closure is provided having a molded plastic tubular ring (16) and a separately formed molded plastic disk (18). The tubular ring includes an overlapping flange (34) at a top and directed inwardly. The ring and the flange define an outwardly open area. The skirt includes an engagement structure for securing the closure to the external surface of the rim. The disk is separately attached on the outer surface of the ring within the open area after the retort process is applied to the sealed bottle.

A tamper-evident closure assembly (10) for a container (12) having an opening (16) includes a cap (18) configured to be secured with the container (12) to cover the opening (16). A tamper-evidencing member (20) is carried by the cap (18) and is configured to provide an indication when the cap (18) is removed from the container (12). The closure assembly (10) further includes an outer shell (22) having a central aperture (50) through which the cap (18) is received. The outer shell (22) and the cap (18) may be configured to cooperate with each other such that the cap (18) is operatively secured to, and mounted so as to be non-rotatable relative to, the outer shell (22). Systems for storing material and methods of closing a container and assembling a closure assembly are also provided.

Capsule composite (1) destinée à être encliquetée sur la bague de verrerie (100) d'une bouteille puis à servir de bouchon vissable et dévissable à volonté, la bague de verrerie étant munie d'au moins un bourrelet annulaire (101). Elle comprend: - une coque (10) avec une jupe (11) munie d'un bourrelet annulaire interne (12); - un premier insert (20), disposé à l' intérieur de ladite coque, muni d' un filet de vissage intérieur (22) un deuxième insert (30) présentant deux portions globalement cylindriques (31 et 32); - la premiere portion (31) étant munie d' un filet de vissage (311) complémentaire de celui dudit premier insert, - la deuxième portion (32) étant munie de moyens d' immobilisation axiale (321) destinés à coopérer avec ledit bourrelet annulaire (101) et de moyens de butée axiale (322), coopérant avec ledit bourrelet annulaire interne (12), de telle sorte que les inserts solidarisé par vissage se trouvent piégés à l' intérieur de ladite coque.
摘要:
The invention relates to a plastic cap (1) for a container (2) with an opening (4). The cap (1) has a first bendable cap part (5), which comprises an oxygen-tight liner (6) to be joined to a circular opening end surface (9) around the opening (4) and, for defined mounting on the container (2) a flange (10), which is arranged to surround an opening portion (3) of the container (2) and comprises a first lifting means (11). The liner (6) and the first cap part (5) are joined to each other so that the liner (6) accompanies the first cap part (5) when this is bent away from said opening end surface (9) for removal from the container (2). For such bending, an annular second cap part (12) is adapted to surround the opening portion (3) of a container (2). The second cap part (12) has a second lifting means (13), which is arranged to cooperate with said first lifting means (11) in such a manner that, when the second cap part (12) is turned for opening of the container (2), the first cap part (5) is bent away from said opening end surface (9).

A closure (10) for a container includes a composite shell having an end wall (14) and a depending annular sidewall (16), the sidewall (16) having molded raised graphics (20) on an outside surface. A method for molding the closure (10) of the invention includes the use of an axially split and laterally openable mold (61) part for producing raised end wall (14) and sidewall (16) graphics (20, 22, 24). A closure (10) can include an inner barrier shell (40), and an over-molded outer shell (50). The barrier shell (40) is impermeable to oxygen and the outer shell (50) has strength to resist pressure and temperature induced stresses during inbottle pasteurization of beer products. The barrier shell (40) includes raised end wall (14) and sidewall (16) graphics (20, 22, 24) which extend through the outer shell (50). The outer shell (50) can include graphics (20, 22, 24) on its end wall (14) and sidewall (16) which are completed by the exposed barrier layer (40) graphics. The barrier shell (40) can be provided with an annular channel, holding the gas seal (46), for receiving a rim of the container, to lock the rim to the barrier shell (40) to prevent disengagement of the rim from the gas seal (46) during pasteurization.

The screw-type sealing cap is comprised of two cup-shaped shells (2, 3) made integral by nesting into each other, the internal shell (3) being made of a flexible plastic material and comprising a female thread (14) and sealing means (10), and the external shell (2) being made of a hard plastic material. A disc (7) made of a material having a gas barrier effect is placed between the bottoms (8, 9) of the external and internal shells. Application: particularly to beverages and other products which are sensitive to gaz exchanges with the outside.

This invention relates to a plastic box comprising a bottom part (3) of a hard plastic, as styrene plastic, for instance polystyrene or styrene acrylonitrile, the edge of the mouth of which is provided with an outer thread, as well as a cover (6), the edge (2) of the mouth of which is provided with an inner thread fitting the thread of the bottom part (3). To combine both good sealing properties and a good function of the thread with a good surface quality and good printing properties, the procedure according to the invention has been that the cover (6) comprises two parts (1, 2), viz. a threaded part (2) of a flexible plastic, as polyolefin, for instance HD-polyethene or polypropylene, with said inner thread and a closing surface to close the mouth of the bottom part (3) and to be sealed against its edge, as well as a casing part (1) of a hard plastic, as styrene plastic, for instance polystyrene or styrene acrylonitrile, to be arranged on the threaded part (2).
