A container comprises: a bottom wall; at least one sidewall connected to the bottom wall, the sidewall terminating in a rolled edge opposite the bottom wall, and the sidewall having an inner and an outer surface, wherein the bottom wall and the at least one sidewall form a container interior; a flexible bag having an open end and being disposed within the interior of the container; and a slide ring comprising a circumferential portion which is substantially vertical or vertical and a finger extending therefrom, wherein the slide ring is affixed to the open end of the bag and disposed adjacent the outer surface of the sidewall, below the rolled edge, wherein the finger of the slide ring is angled inwardly toward the sidewall and frictionally engages the sidewall, and wherein vertical adjustment of the slide ring vertically adjusts the bag within the interior of the container.

A container assembly (10) includes a container body (12) having a side wall(14) encircling an axis, and a metal end (30) for attachment to an upper edge(16) of the side wall via heat-sealing. The outer peripheral region is shaped prior to application to the container body such that an annular channel is defined between an inner chuck wall and an outer chuck wall of the metal end. The metal end is pushed straight onto the side wall such that the upper edge of the side wall is received into the channel. The surfaces of the side wall and the opposing surfaces of the chuck walls have heat-sealable material (26) thereon. The metal end is heated to melt and fuse the heat-sealable layers, thereby sealing the metal end onto the side wall. The metal end is shaped such that the free edge of the outer chuck wall is not exposed.

A retort container includes a metal end applied and sealed to an all-thermoplastic container body by a crimp-seaming or double-seaming operation. The metal end has an outer curl joined to a chuck wall that extends down from the curl. One or both of the inner surface of the container side wall and the outer surface of the chuck wall has/have a heat-sealable material thereon. The metal end is crimp-seamed or double-seamed to the container body and the heat-sealable material(s) are heated to soften or melt such that the interface between the chuck wall and the side wall is fused. The interface is oriented along a direction relative to internal pressure exerted on the metal end such that stress on the interface caused by the internal pressure is predominantly shear stress.

An assembly of a container and a closure. The container has a rim defining an upper sealing surface formed of a heat-sealable material, and an external screw thread extending helically along an outer surface at a location spaced below the rim. The closure includes a screw cap assembled with a separately formed disk inserted in the cap, the closure defining an internal screw thread for attaching the closure to the container when the closure is rotated in a first direction. The disk is constructed of a laminated metal having an upper metal layer and a lower heat-sealable layer affixed to an underside of the metal layer. A heat seal between the heat-sealable layer of the disk and the upper sealing surface of the rim affixes the disk to the rim such that the disk seals closed the open top end of the container.
