A container comprises: a tub (22) having a bottom (50) and four sides (56, 58, 60, 62), adjacent said sides joined at junctions; and a closure (24). The closure comprises: a lid (28); a living hinge member (26) unitarily formed with the lid and coupling the lid to the tub so as to allow the lid to shift between a closed condition and an open condition, the living hinge having an insertion portion (222) received in a pocket (82) of the tub.

The invention relates to a lid (1) for closing a can having a tubular side wall (3) provided with a top opening and with an internal radial collar disposed substantially at the same level as said top opening, said lid (1) being provided on its “bottom” face (2) with an elastically deformable annular sealing gasket (4) that is suitable for coming to bear against said collar, when the top opening of the can is in the closed state in which it is closed by said lid (1). In the non-deformed state, said sealing gasket (4) is in the general shape of a half-torus having its convex side facing outwards from the lid (1).

The present invention is a tamper-resistant and tamper-evident container for holding solid and liquid goods, such as food items. The container has a base portion with a male member extending upwardly from the base and extending about an opening in the base, the outer surface of the male member having a guard lip extending outwardly. The container has a cover with a female member extending upwardly for frictionally engaging the male member when the container is closed. The guard lip renders the lower edge of the outer portion of the female member relatively inaccessible. The container has a hinge connecting the cover to the base having a removable portion that may be removed to facilitate opening the container.

A beverage container comprises a bottle (2) and is sealed by a lid of resilient material. The bottle includes a neck (8) defining an opening and the lid includes a closure plate (32), integral with which is a depending skirt (18) extending around the outer surface of the neck. The skirt (18) carries an annular flange (20), which is in sealing engagement with the underside of the downwardly directed annular shoulder (14) on the outer surface of the neck. The annular flange (20) is connected to the skirt (18) by an integral hinge. The internal surface of the skirt (18) carries an annular protuberance (52), which is in sealing engagement with one side surface of the annular flange, the other side surface being in sealing engagement with the outer surface of the neck. The said one side surface of the annular flange includes an annular portion which extends downwardly and inwardly and is in contact with a corresponding annular portion on the surface of the annular protuberance (52).

An airtight container includes a jar, a cover, a sealing ring and a check valve. The cover includes an opening defined therein. The sealing ring is used to block a gap between the cover and the jar when the cover is located on the jar. The check valve includes a plug and a ball. The plug is fit in the opening and made with a chamber and a tunnel in communication with the chamber. The ball is used to contact the wall of the chamber when air tends to enter the jar via the check valve. The ball can however be lifted from the wall of the chamber by air leaving the jar.

A food container made of thin plastic sheet material comprises a bowl and a lid, each having a peripheral sealing region with a downwardly facing channel generally shaped like an inverted “U”. The outward edges of the channels are lockingly engaged. The channels mate and engage to form a primary seal at a conical interface and a secondary seal at a rib. The rib may be on either the base, the lid, or both. Leverage provided by elastic forces in the lid's channel tightens the seals.

A packaging system includes a container and an unopened lid. The unopened lid includes a central planar region and a lid rim. The lid rim has a lid rim inner wall, a lid rim outer wall, a lid flange and a first tab. The first tab extends in a plane parallel to the central planar region. The first tab also extends outside the lid rim outer wall. A partially cut region is located on the lid rim outer wall, extends around most of the lid rim outer wall, and extends adjacent the first tab. The lid flange extends in a plane parallel to the central planar region. The lid flange also extends outside the lid rim outer wall. The container includes a container flange. The lid flange is welded to the container flange.

A rigid polymer domed food container system suitable for heated food products is described. Recessed vents in the lid of the food container systems permit stacking of multiple container systems while allowing heated gases to escape without restriction. Other features of this container system include the retention of food product within the central region of the tray, rigidized handholds to allow the consumer to lift the heated container, and a releaseably lockable snap-fit grip mechanism that facilitates opening of the container system among other things.
