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.

A package and a method of forming the package, the package including a primary package; an inner package provided around the primary package; an outer package provided around the inner package and the primary package, such that an air gap is formed between the inner package and the outer package, the outer package including two bodies that are configured to surround opposite sides of the inner package, respectively; and a tape configured to seal the two bodies of the outer package together.

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.

A system for compensating for atmospheric pressure changes for high-altitude transport of packages containing powdered and/or granular material may include: one or more packages including a one-way degassing valve configured to flow gaseous substances produced by the powdered and/or granular material outside the one or more packages. Each package may include: a casing; and a containment element configured to wrap the casing. The casing may include: a main body made of expandable material; a capping device associated with the main body; and an insertion opening in the main body. The capping device may include: a tubular sleeve including first coupling means and a bottom wall; a closure element including second coupling means; and first and second one-way valves associated with the bottom wall. The first one-way valve can be configured to allow insertion of gases. The second one-way valve can be configured to allow outflow of gases.

An array of toilet tissue products comprising first and second packages, where first package conveys one of strength and softness, and where the second package conveys something different than the first package. Lint, basis weight, total dry tensile, absorbency, and softness are common intensive properties of the first and second toilet tissue products and one or more of these common intensive properties can be different between the first and second toilet tissue products.
