Description

[Detailed Description of the Invention] The present invention relates to a button injection device whose purpose is to prevent inadvertent discharge by disabling the depression of the injection side when an aerosol product is not in use, thereby increasing safety.

Below, the drawings showing the embodiments of the present invention will be explained.
is a button cap with a locking protrusion 2 provided on the inner periphery of the lower opening 1 and fitted into the upper clamping part 3 on the end side of the aerosol valve configuration,
A locking protrusion is locked to the lower side of the fastening to fix it to the aerosol container, surrounding the valve component end 5, the injection button C, etc.

In addition, the button cap A has left and right walls 8 erected from the front wall 6 and rear wall 7 as one unit so as to create a four-way groove in the diametrical direction on the upper surface, and has an injection direction opening 9 on the front side and a push-down port on the rear side. Finger insertion hole 10
is provided so that the injection side C standing up in the window hole 11 can be pushed down from the outside.

12 is a vertically elongated window hole provided in the rear wall 7 of the button cap A.

On the injection side C, the valve stem 1 is inserted into the center hole of the shaft cylinder part 13 leading to the nozzle.
4 are fitted and connected, and the shaft cylinder lower part 1 is connected from the lower edge of the outer wall 15 on the injection side.
3a protrudes slightly longer, and on the outer periphery of the lower part 13H of the shaft cylinder, a lower end 16 of a reinforcing bridge, which is usually made by projecting out during molding of the injection side C, is placed in the gap between the shaft cylinder part 13 and the outer wall 15, leaving the lower end 13b of the shaft cylinder. to form a hanging protruding shoulder portion 16a.

Reference numeral B denotes a slide component, which is composed of a knob portion 17 and an annular portion 19 connected to the tip thereof through a bridge 18. It is placed on one end 5, and the lower end 13b of the shaft cylinder is fitted into the elliptical hole 20, so that the slide component B can be slid from side to side in the longitudinal direction of the elliptical hole 20.

Further, the upper edge 19a of the annular portion 19 is provided so as to be able to slide while being guided in contact with the shoulder portion 16a of the lower end 16 of the reinforcing bridge, and a cut groove 21 is provided in the upper edge 19a in the axial direction. The lower end 16 of the reinforcing bridge is placed directly above the notched groove 21 in either the forward or backward position of the sliding part B so that it can be received, and the shoulder part 16 a is engaged with the other upper edge 193. Stop and make it impossible to press down the injection side C.

An enlarged portion 18a is provided at the rear of the bridge 18, so that a stepped portion 18b is provided facing the injection side C and abuts against the rear circumferential wall of the injection side C at the forward position of the slide component B to serve as a stopper.

The bridge enlarged part 18a extends through the vertically elongated window hole 12 and protrudes to the outside of the button cap A, and is connected with a knob part 17 so that the user can move the slide part B forward or backward as desired.

Incidentally, the stopper of the slide component may be formed by abutting the front and rear inner circumferences of the annular portion 19 against the lower end of the shaft cylinder.

As described above, the present invention installs the annular part between the valve component end and the shoulder of the reinforcing bridge of the injection button by fitting it into the lower end of the shaft cylinder, and making it possible to move forward and backward in the diametrical direction from the outside of the button cap. A notched groove is provided on the upper edge of the annular part so that the notched groove matches the shoulder of the reinforcing bridge in either the advancing or retracting position of the slide component. It is possible to lock the part to ensure that the injection button cannot be pressed down, and the structure is simpler than that of a rotary structure as it is a forward and backward movement. It has characteristics that can be used for.
