  In the present embodiment, the sliding amount of the button portion 1 can be changed by appropriately setting the length of the protruding portion 2 and the length of the sliding portion 13. With this configuration, if the sliding is performed up to a predetermined amount, the pressing amount of the operation plate 12 and the stem 38, that is, the injection amount is proportional to the sliding amount, so that the injection amount can be adjusted.

  In the present embodiment, the protrusion 2 is provided on the button 1, but the protrusion 2 can be removed from the button 1. Thus, when the protrusion 2 is removed, the cover 11 is rotated by the protrusion 2 even if the stem 38 is slid in a certain direction when the button 1 is slid from the initial position. And the injection port 35 is not covered. That is, since the injection direction of the contents of the aerosol container 40 is not changed, the degree of pressing of the stem 38 is maintained when the pressing force (arrow G) of the operating plate 12 and the repulsive force (arrow H) of the stem 38 are balanced. Then, it is also possible to maintain the continuous injection state in the normal injection direction.

  Thus, according to the cap 30 in the present embodiment, when the user removes the gas from the aerosol container 40, the gas injection direction is changed from the normal injection direction to the lower side than the injection port 35. It is comprised so that. Therefore, even if the user draws out the gas from the aerosol container 40 and accidentally directs the injection port 35 toward the fire, the contents are not directly sprayed into the fire, and a fire or the like is prevented. It is possible to prevent. Furthermore, since the operation plate 12 of the cap 30 in this embodiment has the inclined portion 22, when the injection direction is changed by the cover portion 11, the escape route of the injected matter along the inclination of the inclined portion 22 is provided. It is possible to prevent the periphery of the cover part 11 from getting wet by being formed and the sprayed material spreading in the form of a mist.

  Further, according to the cap 30 in the present embodiment, when the gas in the aerosol container 40 is degassed, the cover portion 11 is rotated while abutting against the projection portion 2 of the button portion 1 described above, whereby the injection port 35. Is covered with the front surface 11d, the left and right side surfaces 11c, 11c, and the upper surface 11a. Since the injection direction of the contents in the aerosol container 40 is changed by covering the injection port 35 with the four surfaces in this way, even if fires are present in the front direction of the injection port 35, The contents are not sprayed on fire.

  The connecting portion between the operating plate 12 and the cover portion 11 is configured as a thin hinge portion 11e (weakly rigid portion), and the cover portion 11 rotates around the hinge portion 11a. The cover portion can be easily rotated with a relatively small force, and can be operated even with one finger, so that the easy-to-use cap 30 can be provided.
