Disclosed herein are embodiments of therapeutic substances that contain solid sodium percarbonate for use in a bath, and packaging for the therapeutic substances. The solid sodium percarbonate can be dissolved in a liquid, such as water, to produce a hydrogen peroxide solution. Hydrogen peroxide solutions can be provide beneficial effects to a user. The titrated sodium percarbonate can be mixed with other chemicals/materials in a pre-made packaging for ease of storage and using with a bath.

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.

A film for gas discharge includes an inner film member, an outer film member, adhesive for securing the inner and outer film members together, an inlet through the inner film member, an outlet in the adhesive adjacent to ends of the inner and outer film members, a release member between the inlet and the outlet, and a valve on the release member. The valve may close the release member to block a passage from the inlet to the outlet or open the release member to unblock the passage. A bag made from the film for gas discharge is also provided.

A method of making a one-way gas release valve for releasing gas pressure from within a coffee container comprises pre-oiling a relatively narrow dry strap of flexible material and laminating the pre-oiled dry strap between relatively wide ribbons of base and cover material with the dry strap overlying spaced vent patterns in the base material. Alternatively, the base material may be pre-oiled or both the base material and the dry strap may be pre-oiled. The dry strap and base may be made of PET and the cover may be made of mPET. Gas release valves are then die cut from the resulting web with each valve containing a vent pattern. Pre-oiling of the dry strap and/or the base can be accomplished through a roll metered process to insure that the oil is applied in precise amounts and with consistent thickness and coverage. Since the oil is applied during fabrication of the gas release valves, the vent patterns in the base can be configured to function also as a filter to prevent coffee grinds from migrating into the valve.

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.

According to embodiments, a pressure relief mechanism comprises a case with an installation hole formed therein, and a pressure relief valve. The pressure relief valve comprises an insertion portion which comprising a vent path formed in an axial portion of the insertion portion and a slit formed in a peripheral wall portion of the insertion portion so as to communicate with the vent path, a pedestal portion provided at an outer end of the insertion portion, a locking portion provided at an inner end of the insertion portion and locked on an inner edge of the installation hole, and a ring-like seal member interposed between around the installation hole and the pedestal portion, the seal portion comprising an elastic member.

A method of manufacturing a delaminatable container is provided that is capable of uniformly delaminating the inner bag from the outer shell. According to the first aspect, a container body is formed having an outer shell and an inner bag. The inner bag preliminary delaminated from the outer shell in an entire circumference of a storage portion of the container body by rotating the container body while pressing the storage portion with a pressing mechanism from outside for compression or by moving the pressing mechanism along an outer circumference of the container body.

In flexible package, a one-way valve may include a substrate forming a portion of the flexible package and having at least one inlet score, a top sheet having at least one outlet score and secured thereto by an adhesive to define a valve chamber in which the substrate and the top sheet are not permanently adhered to each other, and a liquid film within the valve chamber and adhering the top sheet to the substrate within the valve chamber until a pressure differential exists causing gases to pass through the one-way valve. The inlet scores and the outlet scores may be non-linear, or may be linear scores that are not parallel to each other to prevent the scores from collapsing on themselves and preventing gas flow when the package buckles.

Flexible containers with structural support frames including dispensing and venting structures.
