DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawings, 1 is a conventionally known aerosol can, and an annular protrusion 2 is formed around the upper end of the body and the outer periphery of the top wall. The stem 4 that penetrates the top wall and ejects the liquid in the can by being pushed downward is biased upward and stands up.
[0009]
The lower end of the cylindrical portion 12 is fitted to the outer surface of the annular protrusion 2 so that the cover body 11 as a topped cylindrical body stands. As shown in FIG. 2, the cover body may be formed in a cylindrical shape at the lower part and a rectangular cross section that is long in the front-rear direction. The upper front surface has an opening 13 and an upper edge of the opening. A trigger 16 protrudes from the front edge of the top wall 14 through a thin hinge 15. The trigger has side plates 17 and 17 on both right and left sides, and these side plates have a triangular shape with a wide upper portion and a narrow lower end. Since this is for swinging a swing member to be described later, instead of the triangular side plate, a pressure contact protrusion may be provided only on the upper rear surface of the trigger. The trigger 16 is provided with a liquid ejection window hole 19 and a fitting hole 20 is formed in the lower part. The trigger can be placed on the top surface of the top wall 14 by swinging around the thin hinge 15 as shown by a two-dot chain line in FIG. 14 A fitting 21 is provided on the top surface of the top wall so as to maintain the state of being placed on the top surface.

Reference numeral 31 denotes a pressing head which projects the nozzle 33 forward from the upper part of the standing cylinder 32 in which the lower end of the cylinder part is fitted to the upper outer surface of the stem 4 so that the stem can be pressed down.
[0011]
41 is a swinging member, and the rear end portion is pivotally attached 42 in the upper rear of the cover body, the arm 43 protrudes forward, and the lower end of the pressing rod 44 suspended from the lower surface of the arm is connected to the front of the pivot attachment 42. A blindfold plate 47 with a through hole 46 that is placed on the upper surface of the upright cylinder 32 located at the top, projects an inclined plate 45 obliquely forward from the front end of the arm, and loosely fits the front end of the nozzle 33 from the lower end of the inclined plate. , And the lower end of the blindfold plate is brought into contact with the inner surface of the lower edge portion of the cover body opening 13. However, the blindfold is not necessarily required because it hides the inside of the cover and prevents dust and the like from entering the cover.
[0012]
The cover body 11, the pressing head 31, and the swing member 41 are each integrally formed of a synthetic resin material.
[0013]
In the above configuration, when the trigger 16 is pulled backward from the state of FIG. 1, the pressure contact projection 18 moves upward and backward due to the swing of the trigger around the thin hinge 15, and thus the inclined plate 45 of the swing member 41. Thus, the inclined plate 45 is pressed downward. Then, the swinging member 41 swings downward about the pivot 42 at the rear end, so that the pressing bar 44 presses down the upper surface of the standing cylinder 32 of the pressing head, and the stem 4 is also pressed down. The liquid in the aerosol can is ejected 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 swing member 41 and the trigger 16 are returned to their original positions.
[0014]
When the trigger 16 is swung upward and rearward after the liquid ejection is finished and placed on the top surface of the top wall 14 of the cover body 11, the trigger operation cannot be performed in this state.
[0015]
【The invention's effect】
The present invention is configured as described above, the trigger 16 is suspended from the front edge of the cover body top wall 14 via a thin hinge, and the pressure contact projection 18 attached to the upper rear surface of the trigger 16 is provided with a swing member. Since the lower end of the pressing rod 44 that is suspended from the arm 43 is placed on the upper surface of the upright cylinder 32 of the pressing head 31 because the pressure plate 44 is pressed against the front surface of the inclined plate 45 projecting downward from the front end of the arm 41. Since the rear end of the arm is pivotally attached 42 in the upper rear part of the cover body 11, the swing member 41 can be swung downward about the pivot 42 by swinging the trigger 16, and thus the pressing It is easy to push down the push-down head via the bar 44. Since the trigger 16 can be placed on the top wall 14 of the cover body by swinging upward and backward, in this state, the trigger is not carelessly operated and liquid is not ejected, and the trigger is tilted outward. If it protrudes toward the top, it should be a hindrance to touch other objects, but it does not get in the way when placed on the top wall 14 as described above.
[0016]
In addition, by hanging a blindfold plate 47 with a through hole 46 in which the front end of the nozzle is loosely fitted from the lower end of the inclined plate 45, the opening 13 on the front surface of the cover body peripheral wall can be closed, the appearance can be improved and dust and the like can enter the cover body. It can be prevented from entering.
