An insert for a flow wrapped packaging assembly has a bottom wall (18) and a peripheral wall (20) extending from said bottom wall to define an interior volume (21) for containing product (14). The insert has a tongue (20) at a top end of the peripheral wall which is movable between a closed position in which it at least partially closes the interior volume at the top end of the insert and an open position in which it does not impede access to the interior volume. The insert (12) can be top-filled when upright with the tongue open and then moved to a horizontal orientation for flow wrapping using a HFFS process with the tongue closed to prevent the contents spilling out. The insert is particularly suitable for enabling a plurality of disc-shape products, such as beverage pads, to be flow wrapped using HFFS processes.

The invention is directed to a one-way valve for a flexible package which comprises a first film layer having at least one first cut line and a second film layer having at least one second cut line, wherein the lines are offset from one another. An adhesive layer is disposed between the film layers. The film layers and the adhesive layer define a valve area wherein the first film layer and the second film layer are not permanently adhered to each other. The second cut line fluidly connects the interior of the flexible package to the valve area and the first cut line fluidly connects the valve area to the ambient atmosphere surrounding the flexible package. The adhesive pattern within the valve area creates a gas flow channel from the second cut line toward the first cut line.

In an embodiment, the invention comprises a container comprising: a base; at least one sidewall extending upwardly from the base and terminating in a top edge, wherein the at least one sidewall is paper-based; a removable flexible membrane adhered to the top edge, wherein the membrane comprises a one-way valve; a liner ply at least partially adhered to an interior surface of the sidewall, wherein the liner ply is configured to at least partially release from the sidewall upon a pressure differential between the pressure within the container and the external pressure.

A pressure relief blow-out plug includes a body including an inboard end and an outboard end, and an inboard flange extending radially outwardly from the inboard end of the body. A package includes a container including a wall having interior and exterior surfaces, and a pressure relief passage extending along a longitudinal passage axis and having a circumferential passage surface extending through the wall between the interior and exterior surfaces, wherein the pressure relief blow-out plug is carried in the pressure relief passage.

A delaminatable container excellent in productivity is provided. According to an exemplary aspect, a delaminatable container, includes a container body having an outer shell and an inner bag, the inner bag delaminating from the outer shell and being shrunk with a decrease in contents, wherein the container body includes a bottom seal protrusion protruding from a bottom surface of a storage portion to store the contents, and the bottom seal protrusion is a sealing portion of, in blow molding using a cylindrical laminated parison provided with an outer layer constituting the outer shell and an inner layer constituting the inner bag, the laminated parison and is bent.

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.

A bag is formed in a gusset bag shape, and sections respectively extending along the short-side portions of a pair of front and back principal-surface film portions are each joined together as end joint portions, to thereby seal frozen food inside the bag. In each end joint portion: the pair of V-shape segments of a side-surface film portion, which is folded inward in a V-shape, is not joined together; and an end of the side-surface film portion is joined only to the ends of the pair of front and back principal-surface film portions extending along the respective short-side portions thereof, to thereby form a side joint region formed so as to expand in a V-shape, each side joint region being formed by joining the end of the side-surface film portion and the ends of the respective principal-surface film portions extending along the short-side portion thereof.

A pressure relief valve (1) comprises a main body (2), at least one through opening (51), which extends through the main body (2), a diaphragm (6), which is arranged over the at least one through opening (51), and a fluid (8), which is provided on the main body (2), the fluid (8) being arranged between the diaphragm (6) and the main body (2), the main body (2) having a first sealing region (21), a second sealing region (22) radially outside the first region, and a third sealing region (23) radially outside the second region, the regions being respectively formed as continuously closed, the at least one through opening (51) being arranged between the first sealing region (21) and the second sealing region (22), and the diaphragm (6) covering the first sealing region (21), the second sealing region (22) and the third sealing region (23).

A pressure relief blow-out plug includes a body including an inboard end and an outboard end, and an inboard flange extending radially outwardly from the inboard end of the body. A package includes a container including a wall having interior and exterior surfaces, and a pressure relief passage extending along a longitudinal passage axis and having a circumferential passage surface extending through the wall between the interior and exterior surfaces, wherein the pressure relief blow-out plug is carried in the pressure relief passage.

In a generator including a fuel tank that stores liquid fuel, the fuel tank includes a fuel inlet and a breather passage formed by a pipe member through which an inside and outside of the fuel tank communicate with each other, and the pipe member is provided with a valve that blocks the breather passage at normal time and opens the breather passage by a pressure of a predetermined value or higher.
