A package includes a closure and a container. The closure is adapted to mate with a brim of the container to close a top opening arranged to open into an interior product-storage region formed in the container.

A container for dispensing a liquid can include a body and a seal. The body can include a plurality of walls that define an interior storage volume, an outlet through a first wall of the body for dispensing the liquid, and a vent opening. The seal can cover the vent opening. The seal can include an adhesive to removably couple the seal to the body of the container. The vent opening can include a plurality of openings, and the seal can cover all of the openings.

A dispenser for discharging a pharmaceutical or cosmetic medium having a discharge head with a discharge opening, a container for storing the medium prior to discharge, an elastically deformable outer container, and a dimensionally flexible inner container arranged in an interior of the outer container. A ventilation channel is provided, through which the interior of the outer container is connected to an environment for pressure compensation by compensating air. The ventilation channel is delimited in at least some regions by a self-adhesive label, or the ventilation channel has a self-adhesive label and has a gas-permeable surface portion. The gas-permeable surface portion is arranged in the ventilation channel or on one of the ends of the ventilation channel, such that the air passing through the ventilation channel also passes through the gas-permeable surface portion.

Proposed is a gas discharge valve for a packaging material, the gas discharge valve being attached on an upper surface of a packing material in a manner that covers a through-hole formed in one side of the packing material and being configured to discharge to the outside thereof only gas within the packing material, the gas discharge valve including: a high-adhesiveness layer attached to an external surface of the packing material and adhered to a portion of the external surface in the vicinity of the through-hole; and a low-adhesiveness layer formed inside the high-adhesiveness layer and adhered to cover a top opening of the through-hole, where, when gas occurs within the packing material, the low-adhesiveness layer is inflated by pressure, a portion thereof is raised, and the gas is discharged, and when the pressure is released, the low-adhesiveness layer seals the through-hole, thereby blocking introduction of outside air.

A one-way valve, a food package comprising such a one-way valve and a method for manufacturing such a one-way valve is disclosed. The valve comprises a first membrane and a second membrane having a smaller surface area than the first membrane and furthermore being fixed to a bottom surface of the second membrane. The valve is furthermore adapted to be fixed to the food package and cover the aperture such that a canal is formed between the food package and the second membrane when a gas pressure inside the food package exceeds a threshold value, the canal extending from the aperture to the peripheral edge of the first membrane along the second membrane.

A self-venting adhesive patch and method of manufacture for frozen food product packages is provided. The patch is made from a film material having a permanent adhesive zone applied to a surface of the film material. A releasable adhesive zone adjacent to the permanent adhesive zone is defined on the surface of the film material and is also provided to allow for venting while cooking. A non-adhesive zone within the permanent adhesive zone on the surface of the film covers a vent formed in a microwavable packaging material covered by the self-venting adhesive patch. The non-adhesive zone directs steam pressure towards the releasable adhesive zone. A package formed from the microwavable packaging material vents steam to the self-venting adhesive generated during cooking of contents of the package. The steam expands the non-adhesive zone and vents into the releasable adhesive zone, allowing steam to be vented from the self-venting patch.

A container for receiving animal feed, in particular wet feed, including a base surface and a lateral surface protruding from the circumference of the base surface such that animal feed is received in the receiving area formed by the base surface and the lateral surface and can be emptied through an opening formed by the lateral surface circumference facing away from the base surface. The base surface is operatively connected to an opening element for opening a hole in the base surface. Also provided is animal feed being received in the receiving area of a container, to a method for producing a container, and to a method for filling a container with animal feed and/or food.

A package suitable for storing and cooking foods without user manipulation includes a venting mechanism actuated primarily or exclusively by temperature, rather than pressure. A vent hole can be sealed by a patch attached by a thermoplastic adhesive having a selected, well characterized Tg, or the patch itself can be a thermoplastic polymer having a selected Tg. The patch can be convection-heated, or a microwave absorbing susceptor material can be applied to the adhesive or patch for direct microwave heating. The patch can include a region that is melted by convection or by a susceptor material. A porous patch can be sealed by a low melting temperature polymer or by thermally sensitive ink. And/or, microwave susceptor material can be applied directly to a package wall and can melt a ventilation hole through the wall when a specified amount of microwave energy has been applied.

A method of manufacture and an adhesive patch vent is provided for application to a flexible packaging material. A fabric material has an adhesive applied to its surface. The adhesive being applied to outer portions of the fabric material where a central portion is adhesive free. The adhesive patch vent is applied to an interior of a flexible package material where the adhesive free portion aligns with a perforation in the flexible package material. The adhesive vent patch enables air to be expelled from a package but is resistant to damage to the exterior of the bag. In addition a food grade oil resistant adhesive is utilized.

A container (2) for food and/or beverage type items is at least partially defined by two or more wall portions including at least a first sidewall portion, and at least one thin or foldable wall portion (6). The container also includes a base portion and a lid (4). It is convertible between a first substantially flattened storage or transport condition and a second in-use or expanded condition by manipulation of the wall portions and/or base. The thin wall portion (6) is formed or located between a first sidewall portion and the base, and it is between 0.25 mm and 0.5 mm thick.
