A container lid and lock ring combination includes a lid for a container and a lock ring configured to extend loosely around the lid. The lock ring is configured to be tightened for securing the lid to a container. A joint connects the lid and the lock ring to one another.

A paperboard packaging container includes a sealing arrangement comprising a lid and a sealing rim. The packaging container further includes a circumferential lid sealing member applied in the lid. The sealing rim forms a closed loop extending around the container opening. The sealing rim further comprises a first sealing surface arranged at an upper end edge of the sealing rim and is arranged to seal against a second sealing surface constituted by the circumferential lid sealing member when the lid is in a closed position. The sealing arrangement furthermore includes a frame structure forming a closed loop extending around a periphery of the container opening and is connected to the sealing rim. The lid is connected to the frame structure by a hinge member and a locking arrangement.

A closure (20, 20A, 20B) for a container (22) with an outwardly projecting flange (25). The closure including a skirt (50, 50A, 50B) for attaching the closure (20, 20A, 20B) to the container (22). The skirt (50, 50A, 50B) has an annular, flexible retention member (66, 66A) extending laterally inwardly from a lower end portion (54, 54A, 54B) of the skirt (50, 50A, 50B) to define a connection (62, 62A, 62B) therebetween. In one form, the flexible retention member (58, 58A, 58B) has (a) an initial, undeflected configuration, (b) a deflected configuration rotated away therefrom about the connection (62, 62A, 62B), and (c) a proximal end surface (126, 126A) located at the connection (62, 62A, 62B) defining a shoulder when the flexible retention member (58, 58A, 58B) is in the undeflected configuration. In another form, the flexible retention member (58, 58A, 58B) is movable into the deflected configuration when subjected to an axial force of between about 100 Newtons and about 150 Newtons.

A container includes a lid base and a compressible portion. The lid base has a channel and configured to receive a lid. The compressible portion is connected to the lid base. The compressible portion includes a one-way valve in air communication with the channel. Another container includes a compressible portion and a container base. The compressible portion includes a bellow body, which includes at least two convolutions, each including a first living hinge and a first sidewall, at least one second living hinge positioned between the at least two convolutions and connected to the first sidewalls, and a movable bump structure positioned between the at least two convolutions to space the first living hinges apart and being movable between an outer position and an inner position relative to a container interior.

A closure for a container is described where the container has an open end and a closed end, the closure engaging the open end of the container, wherein the closure comprises: a collar engaging the container; a lid connected to the collar by at least one hinge; wherein to facilitate engagement the collar extends over and surrounds the open end of the container such that an inner surface impinges on, or is immediately adjacent to, an outer surface of the open end of the container; wherein a plurality of beads extend outwardly from the inner surface of the collar to fixedly hold the collar in engagement with the container, wherein said beads are located substantially uniformly relative to each other and occupy less than 50% of the inner surface of the collar.

A container, includes a collapsible portion and a container base. The collapsible portion has a first step structure; a second step structure; and a hinge assembly coupled between the first step structure and the second step structure. The container base is coupled to the collapsible portion. Another container includes a container base; a collapsible portion, coupled to the container base; a lid base, coupled to the collapsible portion; a ring, coupled to the lid base and sandwiching a periphery of the collapsible portion with the lid base; and a lid assembly, coupled to the ring when the container is in a closed status.

A sterile container includes a container pan, a container cover, a closure for closing the sterile container, and a seal or sealing element between the container pan and the container cover. The seal or sealing element is vapor-permeable.

A collapsible food container, comprising a collapsible container and a lid assembly, the collapsible container including an upper portion, a lower portion, and a seating wall, the seating wall coupled to a first end of the upper portion and the lower portion coupled to a second end of the upper portion opposite the first end, the upper portion being collapsible as to transition the collapsible container between an expanded state and a collapsed state, the lid assembly including a rigid collar and a rigid lid, the rigid collar removably coupled to the seating wall of the collapsible container and the rigid lid removably coupling to the rigid collar.

The present invention is directed to a can lid that is child resistant, and at the same time senior friendly, and can be initially installed on a can to be removed by an adult, especially a senior adult, and be put back on the can in the same condition where a child could still not be able to easily remove it. The child resistant and senior friendly can lid provided has a replaceable can lid and a locking member, such that when a can is initially opened, it may be readily resealed. The child resistant and senior friendly can lid has tapered, smooth sides to make the lid difficult to grasp and a sealing ledge on the inside surface to grab the seam roll of the upper edge of the can. The lid sealing ledge is relieved in two areas ninety degrees apart leaving a ridge to maintain a seal when the lid is attached to a can. The can lid will be flexible enough to bend for removal by seniors but resistant to removal by children.
