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 container closure comprises an annular region forming a counterface against which a gas permeable, liquid impermeable sealing element may be applied so as to urge the sealing element into sealing engagement with the rim of a container opening. The annular region comprises a gas pathway from an interior space opposite the container opening to the exterior of the annular region. The gas pathway may be of closed cross-section extending through the annular region. Alternatively the gas pathway may be of open-sided cross-section and provided in the counterface. Yet alternatively the annular region may comprise a washer, with the gas pathway provided at least partly in the washer and/or at least partly in the remainder of the annular region. A gas permeable, liquid impermeable sealing foil for bonding to a container rim is also disclosed.

A plastic container includes a lid adapted for leak-proof sealing state with a base. Mating surfaces of the lid and base rims form one or more proximal seal zones when the lid rim and base rim are in an initially sealed state. Hinge-forming structure extends from a first hinge-joining section of the lid rim to a second hinge-joining section on the base rim. In the initially sealed state the first hinge-joining section superposes over all or part of the second hinge-joining section, the area at which the first hinge-joining-section superposes the second hinge-joining section defines an overlapping portion of the first and second hinge-joining sections. One or more vent channels are formed in either of the lid rim or base rim and located within the radially overlapping portion. The one or more channels form a complete discontinuity in the one or more proximal seal zones. Because the channels are within the overlapping portion, they are protected from tampering access.

A packaged food product for being heated in an oven or heater includes a container with a food and a lid. The container includes an inwards raised bead at the inner wall of the container near the opening end of the container. The lid includes 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. The food is located in 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.
