Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to an aerosol sprayer.

<Prior Art> An aerosol atomizer having a structure of a push button and a guide for performing continuous injection is known.

<Problems to be solved by the invention> Some of the conventional ones have drawbacks such as production loss and higher cost due to the complicated guide structure.

The present invention has been made for the purpose of eliminating the above drawbacks.

<Means for Solving Problems> The present invention has a guide fitted on an upper portion of an aerosol body, a push button fitted on a stem of the body, and the guide having an opening portion at a central portion, A threaded portion is formed on the inner peripheral edge of the opening, and a pressing body for rotating the outer peripheral surface of the push button in the vertical direction is screwed into the opening with the push button inside, and the top surface of the pressing body is a push button. The present invention relates to an aerosol sprayer, which is provided with an operation port.

In the present invention, the guide has an opening at the center and a screw portion at the inner peripheral edge of the opening, and may have any shape, size and material as long as it can be fitted to the head of the aerosol can. Alternatively, it may be rotated in the axial direction.

In the present invention, the pressing body is a cylindrical body having a top surface having an inner diameter larger than the outer diameter of the push button that can be screwed to the threaded portion of the opening of the guide while being vertically movable. A push button operation port is provided on the surface, and the diameter of the operation port is arbitrary as long as it is smaller than the diameter of the top surface of the push button and the pressing operation is not supported.

<Operation> In the aerosol sprayer of the present invention, by rotating the pressing body or the guide in the axial direction, the push button is pushed down so that continuous injection can be performed, and the pressing body or the guide is returned to the original position. Injection is performed.

<Embodiment> The present invention will be described in detail below based on an embodiment.

FIG. 1 is a vertical sectional view showing an example of the implementation of the present invention.
(1) is fitted to the stem (4) of the can head (3) of the aerosol can (2), and the cylindrical guide (5) is attached to the winding part (3a) of the can head (3). Is fitted to the guide (5), and the upper opening (5a) formed as a short cylindrical portion (5c) of which the periphery is hung downward is provided with an inwardly directed screw portion (5b).
Is provided, and the cylindrical rotary pressing body (6) is screwed onto the threaded portion (6d) of the lower peripheral surface (6c) of the pressing body (6). The front surface of the pressing body (6) is provided with an opening (not shown) that does not block the spray (not shown), and the upper surface of the pressing body (6) has an opening (6b) and the push button (1) is at the top. A case is shown in which a catching portion (6a) is provided on the entire peripheral edge so that the surface can be pressed.

During continuous injection (see Fig. 2) during use, the rotary pressing body
Since the pressing body (6) is lowered by rotating (6), the push button (1) is pushed down in accordance with this lowering, the intended purpose is achieved, and the rotating pressing body (at the time of normal injection is ( 6) Top opening (6
It is only necessary to press the push button (1) from b).

FIG. 3 is a vertical cross-sectional view showing another example of implementation of the present invention.
It is substantially the same as that of FIG. 1 except that a plurality of rounded small protrusions (6f) are provided on the inner surface (6e) of the hooking portion (6a) of the rotary pressing body (6). In this case, by providing the small protrusions (6f), there is an advantage that the rotation pressing body (6) can rotate more smoothly.

<Effects of the Invention> The present invention has an excellent effect that, by using the rotary pressing body as described above, the structure is simple, no malfunction occurs, and continuous injection and normal injection can be reliably used.

[Brief description of drawings]

FIG. 1 is a vertical sectional view showing an embodiment of the present invention, FIG. 2 is a vertical sectional view showing a use situation during continuous injection, and FIG. 3 is a vertical sectional view showing another embodiment of the present invention. It is a figure. In the figure, (1) is a push button, (2) is an aerosol can, (4) is a stem, (5) is a guide, (5a) is an opening, and (6d) is a screw part.

Claims (1)

[Scope of utility model registration request] 1. In an aerosol sprayer capable of performing continuous injection, a cylindrical guide 5 is fitted on a can head 3 of an aerosol can 2, and a push button 1 is fitted on a stem 4 of the aerosol can 2. The guide 5 has an opening 5a at the center of its upper surface, and the circumference of the opening 5a is a short cylindrical portion 5 that hangs downward.
c, a threaded portion 5b is formed on the inner peripheral surface of the cylindrical portion 5c, and a pressing body 6 for preventing the push button from rising is rotatably screwed on the lower portion thereof. An aerosol sprayer characterized in that an opening 6b for operating a push button is provided on the top surface of 6, and the outer periphery of the opening 6b is a catching portion 6a that engages with the upper end of the push button 6.
