To solve the above problem, a venting device inserted into a sealing part of a pouch of a secondary battery according to the present invention includes: a housing inserted between confronting surfaces of the sealing part and sealed together with the sealing part; an element made of a metal and disposed in the housing and through which a passage is defined providing gas communication between an inside and an outside of the pouch; and a ball disposed at an outlet-side of the passage, the ball configured to open and close the passage, wherein, in the element, an edge of an inner circumference of a surface of the outlet-side of the passage is chamfered or filleted so as to face the ball, and the element includes: a surface treatment layer formed on the chamfered or filleted surface; and a layer made of a polymer and fused to the surface treatment layer.

There is provided a pack (10) in the form of a stirrer for a hot or cold beverage. The stirrer comprises first and second films (13, 14) sealingly connected around a periphery to enclose a volume in which is disposed a liquid. The liquid is conveniently disposed in an elongate channel (15) formed in one of the films. Openable portions (17, 55) are provided at respective ends of the stirrer, one openable portion (17) allowing the liquid to flow out once opened and the other openable portion (55) acting as a vent. Each openable portion is opened by peeling apart the two films and has a stronger connection (52, 57) provided to limit the opening of the ends.

A package for enclosing at least one item is disclosed. The package includes a first portion having a first surface including at least one protrusion, a second portion having a second surface including at least one indentation, and a hinge connecting the first portion to the second portion. The hinge is configured to allow the package to transition from an open position to a closed position. In the closed position the first portion and the second portion define an enclosed space for enclosing an item. The at least one protrusion and the at least one indentation may provide cushioning and shock absorption for the package and/or may allow the package to nest with another package stacked above or below the package.

A product [11] includes a foldable clamshell-type housing [10] folded to a closed position to contain a pre-formed sensor pad [17] that was formed in situ therein when the housing [10] was in an open position, prior to closing. The housing [10] has an enclosed volume [12] bounded by relatively thin and flexible walls [23, 34], and outwardly extending tabs [18] which facilitate opening. This structure enables the user to easily open the housing [10] to remove the sensor pad [17], a cured silicone composition, by pushing inward on an outer surface of the outer wall [34] of a base section [15] of the housing [10]. This product [11] reduces the amount of manipulation needed to place the sensor pad [17] in a desired position, for example, during installation of a rain sensor system for a vehicle windshield.

A liquid air freshener or delivery device to deliver ingredients from a liquid state to a vapor state, including a thermoformed container, having a flange, incorporates a window ply, through which fragrant material may be disseminated, having a paper or related ply thereunder, and which can absorb the liquid fragrance or ingredients when usage of the freshener or delivery is initiated. Below the paper ply is a seal layer, that seals the fragrance material or ingredients into the base of the container, until such time as the seal ply may be pierced, to allow the liquid fragrance or ingredients to migrate and saturate the paper ply, to initiate usage of the device. The base of the container, or the impregnatable paper ply, may have an integrally formed one or more piercing devices, that can pierce the seal layer, to initiate dissemination of the fragrance material or ingredients, and its scent or other properties, to the atmosphere.

There is provided a pack (10) for a product (12) which is sealingly retained in a volume defined by first and second films (13, 14) sealingly secured about a periphery. The pack has an openable portion through which a liquid contained in the product (12) can be dispensed. One of the films (14) has a pre-formed hinge (20) across at least part of the volume to assist folding of, and liquid extraction from, the product (12). The pre-formed hinge (20) may be in the form of a pre-formed fold line.
