摘要:
A container and closure assembly (10) is provided. A projecting rim (18) surrounds an opening into the container (12) and includes a rim sealing surface (32). The closure (14) is provided for covering the container opening. The closure is formed from a support ring (20) dimensioned to surround the rim of the container and a sealing membrane (22). The ring includes a ring sealing surface (40) positioned concentric with the rim sealing surface. The membrane is sealed to the rim sealing surface and further sealed to the ring sealing surface. The seal (48) of the membrane to the rim sealing surface is separable upon removal of the ring from its position surrounding the rim of the container, while the seal (50) of the membrane to the ring remains in place upon ring removal.

A tray (100) or container (478) which may be hermetically sealed having a flange encapsulated by or formed from injection-mold material. The tray (100) has a flange (116) extending outwardly from a sidewall (114) of the tray, and containing irregularities induced by the creation of the tray (100). An encapsulating material surrounds the flange (116) in substantially uniformly thick manner, and along with the flange (116) defines an encapsulated rim (124). The encapsulating material is generally a plastic such as polyolefin, nylon, or polyethylene, but may also be made from other materials. This encapsulating material covers a portion of the flange (116) and extends a set distance from the flange's (116) outer edge.

The invention relates to a reclosable package 10 which comprises a rigid base member 11, a product 50 placed over said rigid base member, a cover film 13 laid over product 50 and sealed to rigid base member 11 wherein removable reclosure means 14 (114) are embedded in rigid base member 11 and cover film 13 is also sealed to removable reclosure means 14 (114). Also disclosed are a rigid base member 11 having removable reclosure means 14 (114) embedded therein and a method of making the reclosable package 10.

A plastic bag (30) having a reclosable plastic zipper (42) is provided with a tamper-evident, non-reclosable peel seal (40) formed by applying an adhesive (38) to a treated strip adjacent to the interlocking zipper (42). The treatment is preferably by corona discharge, which causes the adhesive used to provide the peel seal to preferentially adhere to the treated strip when the peel seal is broken. A method for manufacturing the reclosable plastic zipper includes the steps of extruding a zipper profile, treating a portion of its surface, preferably by corona discharge, applying an adhesive to the treated portion, slitting the profile lengthwise, and folding over one of the resulting sides of the zipper to interlock them with one another.
摘要:
A container (2) with a repositionable closure device (1), wherein the container (2) comprises a lateral wall (L) having an upper edge (B) and wherein the closure device (1) has a stiffening member (4) which is stably coupled to a sheet- like cover member (3), the sheet- like cover member (3) having an outer peripheral portion (3") designed to be coupled to said upper edge (B) of the container (2) and an inner portion (31 ) coupled to the stiffening member (4). The stiffening member (4) partially overlies the edge (B) of the container (2), the outer peripheral portion (3") of the sheet- like cover member (3) being at least partially separable from the inner portion (31 ), while the latter is held integral with the stiffening member (4) to define a repositionable lid.
摘要:
A method of manufacturing together a support (10) and frame (20) of a container assembly (1), the method comprising: providing a single mould (100) with a first cavity (110) defining the support (10) and a second cavity (120) defining the frame (20); injecting first material into the first cavity (110); and injecting second material into the second cavity (120);
wherein the first and second materials are different materials.
