This disclosure relates to a novel packaging method which includes the steps of packaging a product into a container having a mouth defined by a lip, inserting a metallic-nonmetallic-metallic laminated liner upon the container lip in sandwiched relationship between the container lip and an end panel of an associated closure, and inducing heat in the metallic ply sufficient to fuse one of the metallic plies to the closure end panel and the other of the metallic plies to the container lip. Prefera...

This disclosure relates to a container of thermoformed plastic material having a metallic closure, the closure being of a conventional construction and including a channel terminating in a relatively rigid peripheral skirt, the container having a body terminating at an upper end portion in a bead having a peripheral skirt normally disposed upon the upper end portion of the container body, and the peripheral skirt of the closure being of an internal diameter less than the predetermined maximum di...

This disclosure relates to a container formed of thermoform plastic material and a metallic closure, the closure being of a conventional construction and including a downwardly opening channel in part defined by an outermost peripheral wall terminating in a raw severed edge, the container having a body terminating at an upper end portion in a radially upwardly outwardly and downwardly directed wall, the latter of which joins a generally radially outwardly directed peripheral wall which underlies...

This disclosure relates to a novel packaging method which includes the steps of packaging a product into a container having a mouth defined by a lip, inserting a metallic-nonmetallic-metallic laminated liner upon the container lip in sandwiched relationship between the container lip and an end panel of an associated closure, and inducing heat in the metallic laminate sufficient to fuse one of the metallic laminates to the closure end panel and the other of the metallic laminates to the container...

This disclosure relates to a self-closing dispenser comprising a dispenser body defining a generally elongated passage having exit and entrance end portions, the body being molded from synthetic polymeric material and including two diametrically opposite relatively rigid and immovable upstanding posts, and a pair of resilient concavely outwardly opening walls extending laterally between the posts and axially between the passage exit and entrance end portions. Due to the (1) concave configuration...

A back-off resistant closure for resealable engagement upon a container having a neck with a ring of outwardly projecting ratchet formations includes a generally planar top portion with a depending peripheral annular skirt, the skirt having a plurality of recess formations for matingly engaging the ratchet formations on the container neck, thus preventing unwanted backing-off of the closure from the container, as well as facilitating the removal of the finished closure from conventional injectio...

A dispenser closure for a container includes a body having a generally planar top portion and a peripheral skirt portion depending therefrom to form a cap-like formation, and the top portion is provided with at least one sifter opening, a larger opening for spooning or pouring and a pair of vertically projecting slide guides located thereon in diametrically opposed relation to each other. A substantially planar solid slide plate is also provided and is adapted to slidingly engage the slide guide...

A closure for use in connection with a capped container includes a seal liner provided with a tab portion, and adapted to seal the mouth of the container, a cap liner adapted to be adhered to the tab portion of the seal liner and releasably retained within the cap so that upon opening of the container as by unscrewing the cap, the cap liner is released from the cap and provides an enlarged gripping surface to enable the consumer to more easily open the container.

A linerless closure for use in sealing plastic bottles and jars is disclosed. The linerless closure has a series of concentric annular sealing rings for sealing contact with a bottle mouth. A ridge located between an inner and outer sealing flange provides for a minimum of two sealing surfaces and a maximum of three sealing surfaces with a bottle mouth. A buttress flange spaced inwardly of the inner sealing flange provides additional strength to the inner sealing flange for guiding an irregular ...

A tamper-evident container closure and container assembly with tamper-evident ring which breaks away from the cap as the cap is unscrewed. The cap includes a pawled ring with a plurality of breakable connectors and connection of the pawl tips to the cap providing coupling of the ring to the cap. During assembly, the pawls ride over ratchet teeth on the container breaking the pawl connections to the container. When the cap is removed, the pawls interlock with the ratchet teeth breaking the breaka...
