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.

The invention relates to a plastic container that is blown in a blow mold, having a body, defining an opening is provided, and a disposable closure, which closes the opening and is formed in the blow mold together with the body. A holding strip with a first end and a second end is also formed in the blow mold together with the body and the disposable closure. The first end is permanently fixed to the body, and the second end is permanently fixed to the closure. The body, the disposable closure, and the holding strip are formed as a single piece.

Pressure relief blow out plugs for a container are disclosed as well as methods of using the same. One disclosed method involves providing a glass container that comprises a base and a body extending away from the base. The base includes a wall that defines a pressure relief passage. The method also involves inserting a pressure relief blow out into the pressure relief passage to seal the passage. The plug comprises a first inboard flange extending radially outwardly from the plug body, a stem, and a second inboard flange extending radially outwardly from the plug body and being spaced apart from the first inboard flange by a stem. The first inboard flange includes a first outboard sealing surface that provides an axial seal against the wall of the base of the glass container, and the second inboard flange including a circumferentially interrupted outboard facing retention portion the defines vent gaps.

Disclosed are packaged frozen precooked dough or batter-based food products and methods of heating the food products. The packaged precooked frozen dough or batter-based food products comprises one or more frozen precooked dough or batter-based food products that are encased in a pouch for heating. The pouch is sealed with the exception of the presence of two or more vent holes that function to release air or steam that may otherwise cause the food product to become soggy when they are heated in an oven.

Provided is a heated food packing material including a sheet-like body capable of wrapping a food to be heated; and a penetrating part penetrating the sheet-like body. The heated food packing material is configured to be used for heating the food wrapped therein in such a manner that one surface of the sheet-like body faces outside. The heated food packing material further includes a sheet-like covering part disposed to cover the penetrating part and configured to allow water vapor to pass therethrough.

A device that assists with equalizing air pressure within a bottle with the atmospheric air pressure as liquid is being poured from the bottle and includes one or more relatively short air tubes. The air tubes are situated with an upper inlet rim of the air tubes located flush with or relatively near the bottle rim. Whether an insert or integrated into the manufacture of a container, the one or more air tubes that extend partially into the container allow air to pass into the container as the liquid exits the container. The pressure equalizer not only minimizes or prevents the common glugging effect, but it allows liquid from a bottle to be poured smoothly at any angle and orientation. A cap incorporating a detachable pressure equalizer is also described.

The present invention provides a method for dough processing, a method for providing a container for a dough product, a container, and a product formed by a container.

A steam release standing pouch has a structure in which the sealing portion is reliably peeled, and a content sealing standing pouch formed using the pouch. The steam release standing pouch has a first vapor passage portion. The distance between the inner edge of the tip of the vapor passage portion and the center of maximum expansion, which is the center of the portion where expansion is expected to be maximal, is shorter than either the distance between the inner edge of the first upper side portion and the center of maximum expansion or the distance between the inner edge of the first intermediate side portion and the center of maximum expansion.

A collapsible crate includes a base and a plurality of walls pivotably connected to the base. Each of the walls is a single piece of molded plastic defining a plurality of planks having the appearance of wooden planks, such as with molded-in grain texture, knots and irregular edges. The irregular edges may provide gaps between adjacent planks to provide ventilation to the crate. The knots may include knot holes to provide additional ventilation. The planks may include horizontal planks extending between vertical planks. The vertical planks and horizontal planks may include an interior wall from the edges of which extend ribs toward the exterior of the crate.

The present invention is related to flexible multilayer laminates having an integrated, one-way pressure-release valve for use in a sealed container for packing gas-producing products. The pressure-release valve is partly disconnected from the rest of the laminate, forming an inflatable outlet tube with at least one large outlet opening and lifting off from the laminate under increased pressure in the pack. The one-way pressure-release valve allows for pressure release at low minimum opening pressure in a reliable and reproducible way.
