The containing shell 10 is used for containing the volatile liquid V. The accommodating shell 10 has an accommodating portion 12, and the top end of the accommodating portion 12 forms an accommodating opening 120. The accommodating portion 12 can be made of plastic. In this embodiment, the top edge of the accommodating portion 12 extends outward with an inner edge portion 122, and the rupturable layer 14 is adhered to the inner edge portion 122. In this embodiment, The accommodating portion 12 further extends from the inner edge portion 122 to an outer edge portion 124, and there is a gap between the inner edge portion 122 and the outer edge portion 124. From a plan view, the outer edge portion 124 is located at the inner edge portion 122 Peripheral. The rupturable layer 14 is adhered to the top surface of the inner edge portion 122, for example, can be adhered to the inner edge portion 122 by hot pressing. The inner edge 122 of this embodiment is only shown on one side due to the truncation of the drawing. In fact, the inner edge 122 has a circular shape.

The back shell 30 and the outer shell 60 can be combined to form a shell to accommodate the accommodating shell 10, and the extension portion 122 of the accommodating shell 10 abuts against the top edge of the outer shell 60. The aforementioned volatile liquid V can be, for example, various volatile liquids such as fragrances, deodorants, insecticides, etc. However, the present invention is not limited to the above-mentioned examples. For example, it may also contain solids, such as camphor, desiccant... etc.

The rupturable layer 14 of this embodiment covers the accommodating opening 120 of the accommodating shell 10. The microporous membrane 16 is placed above the rupturable layer 14. The microporous membrane 16 of this embodiment is adhered to the outer edge portion 124 of the accommodating portion 12, for example, can be adhered to the outer edge portion 124 by hot pressing. . The height difference between the inner edge portion 122 and the outer edge portion 124 is greater than or equal to the height of the rupturable layer 14. This drop allows the microporous film 16 to be better combined with the outer edge portion 124 during the hot pressing process, and prevents the rupturable layer 14 from being affected. Impact. 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 membrane 16 is made of a porous material (such as non-woven fabric), or a thin film material such as a polyolefin elastomer (Polyolefin elastomer, abbreviated as POE) is provided with dense micropores. . In addition to being breathable, the microporous film 16 itself can also help the diffusion of volatile liquids by capillary action.
