Description

  The present invention relates to an aerosol cap that is attached to an aerosol container in order to inject the contents contained in the aerosol container, and more particularly to an aerosol button that obtains a cross-shaped wide-angle spray pattern.

  2. Description of the Related Art Conventionally, there is known an aerosol nozzle that is attached to an aerosol container filled with contents such as a deodorant and a liquefied gas (for example, Patent Document 1). This aerosol nozzle can eject the contents from the nozzle body by depressing a push button during use.

  In the aerosol nozzle 100 shown in FIG. 7, a nozzle body 103 is provided on the push button 101, and the inside of the aerosol container 107 communicates with the nozzle body 103 when the stem 105 is pressed. The nozzle body 103 is formed with an outflow passage 109 for flowing out the contents in the axial direction.

  In the nozzle body 103 shown in FIG. 8, the outflow tip portion 111 of the outflow passage 109 is formed in a circular shape. A diffusion split groove 113 orthogonal to the outflow path 109 is formed in the outflow tip 111. A bottom 115 of the diffusion split groove 113 is formed by cutting into the outflow tip 111. As a result, the diffusion split groove 113 and the outflow tip 111 of the outflow passage 109 communicate with each other to form the injection hole 117.

  In use, when the push button 101 is pressed and the valve mechanism (not shown) of the aerosol container 107 is opened, the contents flow into the outflow passage 109 of the nozzle body 103. The contents that have reached the outflow tip 111 diffuse on the inner surface of the outflow tip 111 and are ejected from the outflow tip 111 to the outside. The ejection direction is regulated on both sides by the diffusion dividing groove 113, diffuses only in the vertical direction, and is ejected in a fan shape in a side view having a certain thickness in the horizontal direction. Thereby, the spray pattern approximated to the rectangular shape by front view can be obtained.
