Japanese Patent No. 5155551

  However, since the actuator as shown in Patent Document 1 is provided with a flat-plate-type push button as described above, the pressure surface is wider than that of a normal push button, and a situation in which it is erroneously pressed when not in use is likely to occur. . And when pressed inadvertently in this way, there is a risk that sanitary problems such as wasteful consumption of the aerosol contents and contamination of the surroundings due to the aerosol contents discharged onto the surface of the push button may occur. there were.

  Accordingly, the present invention is intended to solve the above-described problems, and makes it difficult to press a flat-plate-type push button when not in use, and the surroundings are soiled by the aerosol contents discharged by pressing the push button. The purpose is to make it difficult for hygiene problems to occur.

  The present application solves the above-described problems, and is a cylindrical main body positioned on the outer periphery of the aerosol container, and is positioned on the stem side of the aerosol container continuously to the main body, and is independent of the main body. A cylindrical rotating body that is rotatable in the circumferential direction; and an aerosol container that is slidable in the axial direction of the rotating body on the inner periphery of the rotating body and is non-rotatably engaged with the main body. A flat-plate-type pushbutton having an injection port communicating with the stem of the top plate, and a pushbutton disposed on the pushbutton via a hinge portion protruding outward in the radial direction from the rotating body and being pushed. An upper lid that can cover the button is provided.

  By providing the upper cover on the push button as described above, the spray port provided on the push button can be covered, so that the aerosol contents in the spray port are not likely to scatter around when not in use, which is a sanitary problem. Is unlikely to occur.

  Then, one end of the rotating body is provided with a recess that allows the hinge portion to be inserted, and the rotating body is rotated to place the recess at a position corresponding to the hinge portion, thereby pressing the push button. The hinge part slides in the recess to allow the push button to be pushed down, and the hinge part is arranged at a position other than the recess position so that the hinge part is one of the rotating bodies even when the push button is pressed. The push button cannot be pushed down by contacting the end face.

  As described above, by disposing the hinge portion at a position other than the recessed portion, it is possible to make it impossible to push down the push button. It is possible to prevent a situation in which the surroundings are contaminated due to the aerosol content discharged by the pressing. In addition, since the push button can be controlled by a simple configuration of the hinge portion and the recess of the rotating body, it is possible to achieve a simple and compact configuration without the need for any other special configuration. Manufacturing costs can be kept low.

  Further, the main body may be connected and fixed with a cylindrical lower lid that can cover the bottom of the aerosol container. By connecting and fixing the lower lid in this way, the entire aerosol container can be covered with the upper lid, the push button, the rotating body, the main body, and the lower lid, so that the outer periphery of the aerosol container can be safely protected. Various decorations can be applied to the outer periphery of the aerosol container using a material different from that of the aerosol container.

  In addition, the main body, the rotating body, and the lower lid may be continuous and have the same surface. By making the surfaces flush with each other in this way, it becomes easier to hold by hand and the aesthetics can be improved.

  In addition, on the upper surface of the push button, a rising portion surrounding the injection port is provided in an annular shape, and an application body for applying the aerosol contents to the application portion can be stored in the rising portion. There may be. By making it possible to store the application body in the start-up part in this way, it is not necessary to bring the application body from another place at the time of use, and the application work can be started promptly. It is convenient to carry because there is no need to have it separately.

  Further, a plurality of protrusions may be provided on the upper surface of the push button, and an application body may be placed on the protrusions so that a gap can be formed between the application body and the injection port. . By forming an interval between the application body and the injection port in this way, it becomes possible to adhere the aerosol content injected from the injection port over a wide range to the application body facing the injection port. The aerosol content can be efficiently applied to the surface to be coated.

  As described above, the present invention makes it impossible to push down the push button by disposing the hinge portion at a position other than the recessed portion. Therefore, when the push button is not used, the push button is accidentally pressed and the aerosol contents are wasted. It is possible to prevent a situation in which unnecessary consumption occurs or the surroundings are contaminated by the aerosol content discharged by this pressing. In addition, since the push button can be controlled by the hinge portion and the concave portion of the rotating body, a simple and compact configuration can be achieved without the need for any other special configuration. It can be kept low and can be conveniently carried around when going out.
