The rupturable layer 14 provides a sealing function, so that the aforementioned volatile liquid V can be stored in the containing housing 10 without being volatilized, so that it can be stored for a long time. The microporous film 16 is made of a porous material (such as non-woven fabric), or a thin film material such as a polyolefin elastomer (Polyolefin elastomer, referred to as POE) is provided with densely packed tiny pores. . In addition to being breathable, the microporous film 16 itself can also help the diffusion of volatile liquids by capillary action.

In this embodiment, the rupturable layer 14 can be tin foil, aluminum foil, or kraft paper, but the material selection is not limited to the above-mentioned examples. Any material that has sealing properties and can resist the erosion of the aforementioned volatile liquid can be selected as the The material of the fracture layer 14. For example, the thickness of the aluminum film used for the rupturable layer 14 may be 18~75um. Preferably, the ductility of the microporous membrane 16 is greater than the ductility of the rupturable layer 14 in this embodiment. The bursting strength or bursting strength of the rupturable layer 14 is less than that of the microporous membrane 16.
