The present invention relates to a packaged food product for being heated in an oven or heater, the packaged food product comprising a container with a food and a lid, wherein the container comprises an inwards raised bead at the inner wall of the container near the opening end of the container; the lid comprises a recess designed to engage with the raised bead at the inner wall of the container in such a way as to snap-close the container; and the food is located in the container.

A plastic closure embodying the principles of the present invention comprises a closure cap having a top wall portion, and an annular skirt portion depending from the top wall portion. The skirt portion includes an internal thread formation for threaded engagement with the external thread formation of an associated container. In order to facilitate high-speed application, and minimize the use of polymeric material, the closure is configured to exhibit a variation in retention force which decreases in a direction away from the top wall portion of the closure cap.

A resealable cover for a beverage container that holds a carbonated beverage. The cover includes a base engageable with a rim of the container and a lid movable between an open and closed position relative to the base. When in the closed position, a passageway is defined between a portion of the lid and a portion of the base. The passageway permits fluid communication between air surrounding an exterior surface of the cover and a space defined between the lid and an opening in the container. Pressure that builds up under the lid from gas escaping from the liquid may be relieved by outgassing through the passageway. The cover includes latches on the base that engage in notches on the lid to help lock the lid in place. The lid is rotated relative to the base to release the latches and permit the lid to be opened.

A closure includes top wall portion, an annular skirt portion, a continuous plug seal, a top sealing member and a top stop. The skirt portion, the plug seal and the top stop depend from the top wall portion. The top sealing member is located between the plug seal and the skirt portion. The top stop is located between the plug seal and the skirt portion. The sealing member extends to and contacts a top surface, a top portion of the inner radius/corner or the outer radius/corner of the finish of the container when the closure and the container are in mating engagement with each other at an atmospheric internal pressure. At higher internal pressures, the top sealing member and the top stop are spaced from and located above the top surface of the finish.

A container closure assembly for vacuum sealing of bottles and containers includes a cylinder that is resilient. A bore is axially positioned through the cylinder. The bore is tapered so that it is circumferentially larger proximate to a bottom of the cylinder. The bore is configured to insert a mouth of a container. The cylinder is configured to abut a lip of the container to sealably couple to the lip of the container. A regulator is selectively couplable to a top of the cylinder. The regulator is configured to selectively sealably close the bore and to selectively motivate air through the bore. The regulator is configured to extract the air through the bore to partially evacuate the container to couple the cylinder to the container. The regulator also is configured to inject the air through the bore to pressurize the container to decouple the cylinder from the container.

The invention provides a container (10) for the packaging of a fluent product (P) which off-gases, the container comprising: a container body (11) for receiving and storing product and a removable lid (12) for closing the container body; in which the lid is provided with a venting assembly (20, 23a, 23b, 24) extending into the container body; in which the venting assembly has a closed position which is effective to close the container body and a venting position permitting the venting of gas from the container body; whereby, when the container body is partially filled with a fluent product which off-gases, the venting assembly moves to the venting position in response to excessive pressure from accumulated gas, and reverts to the closed position upon release of the excessive pressure, thus effecting periodic venting of the container body; and whereby the spatial arrangement of the venting assembly within the container body provides for venting of the container body independently of the orientation of the container, while retaining the product within the container body. The container is especially suitable for the packaging of viscous or semisolid products which incorporate an oxidizing agent, such as creams or gels for the bleaching or coloring of hair.

Disclosed is a container for keeping fermented food, including a body configured to contain the fermented food therein, a cover configured to close the body, and a sealing sheet configured to maintain airtightness between the body and the cover. The cover includes a plurality of gas flow channels which extend from a center of a bottom surface to an inner peripheral surface, and a plurality of gas discharge channels which extend from an upper end of the inner peripheral surface to a lower end. In addition, the sealing sheet has a through-hole to allow an interior and an exterior of the body to communicate with each other.

One general aspect includes a cap for a the overflow reservoir bottle, including a lower cup having a syncline void, said syncline void having by a wall extending above and below at least one surface of the lower cup. The cap also includes an upper cup with an anticline projection nesting adjacent to the syncline void of the lower cup, and said upper cup affixed to the lower cup, with at least one vent to permit gas to traverse the overflow reservoir bottle.

A closure for use in closing a container which includes a seal liner, and includes side walls with an upper panel which is integral with the side walls. The upper panel has an upper surface defining a recessed relief area which corresponds to a venting location. The recessed relief area of the upper panel represents a location where a sufficient down force is not available for bonding a seal liner at that location to a container neck land surface. As such, the recessed relief defines a venting location for an assembled combination of the closure, container and seal liner.

A container (10) assembly for accommodating a carbonated beverage defining a temperature dependent internal carbonization pressure comprises a beverage container (10, 12) having a body part defining an inner volume for accommodating the carbonated beverage and a cylindrical neck part defining a gas filled head space. The cylindrical neck part further defines a circumferential rim (16, 18) defining an opening (18, 20) and an outwardly oriented surface (24, 26) which extends between the rim (16, 18) and the body part, and has an outwardly oriented circumferential flange (20, 22). The beverage container (10, 12) further defines a burst pressure being higher than the temperature dependent internal carbonization pressure at room temperature. A closure (30, 32) is provided and comprises a closure plate (32, 34) and a cylindrical part. The closure plate (32, 34) covers the opening (18, 20) at the rim (16, 18) and the cylindrical part covers the neck part. The cylindrical part comprises a locking part for arresting the outwardly oriented circumferential flange (20, 22). A flexible sealing ring (10, 40) is provided and is movable between a first position in which the sealing ring (10, 40) is accommodated in a compressed state entirely within a circumferential cavity defined between the cylindrical part of the closure (30, 32) and the outwardly oriented surface (24, 26) of the neck part when the temperature dependent internal carbonization pressure is lower than or equal to the temperature dependent internal carbonization pressure at room temperature, and, a second position in which a larger part of the sealing ring (10, 40) is accommodated in a compressed state within the circumferential cavity, and a smaller part of the sealing ring (10, 40) is located in an uncompressed state within a groove (28, 30) in the cylindrical part and/or in the outwardly oriented surface (24, 26).
