Abstract: An expanded housing (2) including an outer tubular portion (2a), a center-top tubular portion (2b), an annular ceiling portion (2c), and a center-bottom tubular portion (2d) is an integrally molded plastic product. Vertical plate rib-shaped portions (2h) for increasing strength are similarly integrally molded between the outer tubular portion (2a) and the center-top tubular portion (2b). An inner passage region (B) for upward passage of content is set in the center tubular portion (2b). A housing cover (28) provided in such a form as to surround the lower side of the expanded housing (2) forms an outer passage region (A) which is disposed between the housing cover (28) and an outer peripheral surface of the expanded housing (2) so as to extend downward from an upper-end-side inner space region of an inner bag-shaped container (1g) to the inner passage region (B).

Abstract: A fixed-amount spray type aerosol container in which stem rubber is pressed against a mounting cap by a spring provided below the stem connected to a nozzle, and a tank is fixed between a guide bush that fixes the stem rubber and a housing, the container including a valve with a shape stabilizer installed between the guide bush and the tank. The container is nearly free from entry of external air and can spray the contents at a nearly constant amount until the contents nearly run out.

Abstract: An aerosol composition which forms a foam exhibiting a cracking sound upon defoaming when subjected to blow out in the form of a mist or a foam, containing an aliphatic hydrocarbon having a boiling point of -5.degree. to +40.degree. C. The aerosol composition of the present invention has the advantages that a uniform dispersion can be easily formed with using various effective components, that it has an improved fast-drying property and produces an increased foam crackling sound and that it does not affect the environment adversly.
