BRIEF DESCRIPTION OF THE DRAWINGS FIG.
Is a conventionally well-known aerosol can. An annular projection 2 is provided around the upper end of the body 3 by tightening the upper end of the body and the outer periphery of the top wall. From the center of the top wall, the top wall is penetrated. The stem 4 that ejects the liquid in the can is urged upward by the downward pressing and stands up.

The lower end of the cylindrical portion 12 is fitted to the outer surface of the annular projection 2, and the cover 11 as a toped cylindrical body stands upright. As shown in FIG. 2, the cover body may have a cylindrical lower portion and an upper portion that is long in the front-rear direction and a rectangular cross section. The upper front surface has an opening 13 and the upper edge of the opening is formed. Top wall
The trigger 16 protrudes from the front edge of 14 via a thin hinge 15. The trigger has side plates 17, 17 on both left and right sides,
These side plates have a wide upper portion and a triangular shape with a narrower lower end, and the upper end rear portion has a pressure contact protruding portion 18, but since these side plates are for swinging a swing member described later, Instead of the triangular side plate, a press contact protrusion may be simply provided on the upper rear surface of the trigger. A liquid ejection window hole 19 is formed in the trigger 16, and a fitting hole 20 is formed in the lower portion. The trigger can be mounted on the top surface of the top wall 14 by swinging about a thin hinge 15 as shown by a two-dot chain line in FIG. A fitting 21 is attached to the top surface of the top wall so as to be able to maintain the state of being placed on the top surface.

Reference numeral 31 denotes a press-down head, which protrudes a nozzle 33 forward from an upper part of an upright cylinder 32 into which a lower end of a tubular portion is fitted so as to be able to push down the stem to an upper outer surface of the stem 4.

Reference numeral 41 denotes a swinging member. The rear end portion is pivotally connected 42 inside the upper rear of the cover body, and the arm 43 projects forward.
The lower end of the pressing rod 44 vertically suspended from the lower surface of the arm is placed on the upper surface of the upright cylinder 32 located in front of the pivot 42, and the inclined plate 45 is projected from the front end of the arm downward and obliquely forward. A blind plate 47 with a through hole 46 into which the front end of the nozzle 33 is loosely fitted is suspended, and the lower end of the blind plate is brought into contact with the inner surface of the lower edge portion of the cover body opening 13. However, the blind plate is not always necessary because it covers the inside of the cover and prevents dust and the like from entering the cover.

The cover 11, the pressing head 31, and the swinging member 41 are integrally formed of a synthetic resin material.

In the above configuration, when the trigger 16 is pulled backward from the state shown in FIG.
It moves upward and backward by the swing of the trigger around
Therefore, the swing member 41 rides above the inclined plate 45, and the inclined plate 45 is pressed downward. Then, the swing member 41 swings downward about the pivot 42 at the rear end, so that the pressing rod 44 pushes down the upper surface of the upright cylinder 32 of the push-down head, and the stem 4 is pushed down. The liquid in the aerosol can gushes through the push button. Next, when the trigger 16 is released, the stem 4 and the pressing head 31 are raised by the upward bias, and the swinging member 41 and the trigger 16 return to their original positions.

After the ejection of the liquid, the trigger 16 is swung upward and rearward to be placed on the upper surface of the top wall 14 of the cover body 11. In this state, the trigger operation becomes impossible.

[0015]

The present invention has the above-described structure, and the trigger 16 is connected to the front edge of the cover body top wall 14 via a thin hinge.
And a pressure contact projection attached to the upper rear surface of the trigger 16
18 is pressed against the front surface of the inclined plate 45 projecting downward and forward from the front end of the arm of the swinging member 41, and a pressing rod hanging down from the arm 43.
44 Since the lower end is placed on the upper surface of the upright cylinder 32 of the press-down head 31, and the rear end of the arm of the swinging member 41 is pivotally mounted 42 inside the upper rear of the cover body 11, the swing of the trigger 16 causes Moving parts
The push-down head 41 can be easily pushed down through the push rod 44 because the push-down head 41 can be swung downward about the pivot 42. Also, since the trigger 16 can be mounted on the top wall 14 of the cover body by swinging upward and backward, in this state, the trigger is not carelessly operated and the liquid is not ejected, and the trigger is inclined downward and outward. While it should protrude, it should be in the way by touching other objects, etc., but it will not be in the way when placed on the top wall 14 as described above.

The opening 13 in the front surface of the cover peripheral wall can be closed by hanging a blind plate 47 having a through hole 46 into which the front end of the nozzle is loosely fitted from the lower end of the inclined plate 45, so that the appearance can be improved and dust and the like can be improved. It can be prevented from entering the cover.
