Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aerosol sprayer that performs spraying by a trigger operation.

[0002]

2. Description of the Related Art In an aerosol sprayer, a jetting stem is erected in an upwardly urged state by penetrating a central portion of a top wall of a body.
In general, a depression head having a nozzle hole is fitted on the upper part of the ejection stem. When the depression head is pushed down, a mist or the like is ejected from the nozzle hole.

[0003]

In the above-described aerosol sprayer, when the spray operation is performed by holding the can with one hand, the press-down head is pressed down with one finger, usually a forefinger. The pushing operation is not so easy as compared with the pulling operation.Moreover, such a disadvantageous operation requires pushing down the upwardly biased pushing head several times continuously for a certain period of time, so that the spraying operation is further increased. It was difficult.

According to the present invention, by providing a trigger,
In addition to facilitating the spraying operation of the aerosol sprayer with one hand, the fact that the trigger is used can be visually recognized by providing an unauthorized use prevention plate.

[0005]

As a first means, an annular ridge 3 is provided around the upper end of the body 2 and a central portion of the top wall 4 is pierced to urge the ejection stem 5 upward. The aerosol can 1 which stands up in the state, the base member 10 in which the upper surface of the peripheral wall 11 whose lower part is fitted to the annular ridge 3 is formed in the opening 12 in the front-rear direction, and the upper part of the ejection stem 5 are fitted. A stem fitting tube 21 is suspended from the center of the top plate 22 and an injection cylinder 23 having a front half of the top plate as an upper wall projects forward from the front of the stem fitting tube, and the rear portion of the top plate is suspended from the base member. Surrounding wall 11
The trigger 24 is pivotally attached to the rear part, and the trigger 24 is further suspended from the lower surface of the front end of the injection cylinder, and the front parts of the left and right side walls 25 suspended from the left and right parts of the top plate 22 are connected to the left and right parts of the upper part of the trigger 24. Having a spraying member 20 with a trigger
The lower part of the left and right side walls 25 can enter and exit the opening 12 of the base member, and an unauthorized use prevention plate 31 is installed between the front left and right parts of the opening of the base member via a breakable thin piece 30. At the same time, a notch 32 was formed at the lower end of the left and right side walls, and the notch was fitted to an unauthorized use prevention plate.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an aerosol sprayer according to the present invention will be described below with reference to the drawings. Reference numeral 1 denotes an aerosol can, which has an annular ridge 3 provided around the upper end of a body 2 and an outer peripheral portion of a top wall 4 which closes the upper end surface of the body, is fastened around the annular ridge 3 and a central portion of the top wall. And the jetting stem 5 is erected in an upwardly biased state.

Reference numeral 10 denotes a base member. The lower end of the peripheral wall 11 is fitted to a ridge portion except for the rear portion of the annular ridge 3, and the left and right side wall portions of the peripheral wall are inclined inward to form an upper surface of the peripheral wall. It is formed in the opening 12 in the front-rear direction, and the front wall of the peripheral wall 11 is cut off to form an opening continuous with the front end of the opening 12. Further, a rear wall portion of the peripheral wall 11 is extended rearward beyond the annular ridge 3 to form a pivoting portion for pivotally attaching a top plate 22 described later.

Reference numeral 20 denotes a spraying member with a trigger. The stem fitting cylinder 21 fitted to the upper outer surface of the ejection stem 5 has a top plate 2.
(2) An injection cylinder 23 is vertically protruded from the central portion and has a front half of the top plate as an upper wall from the front surface of the stem fitting cylinder. The trigger 24 is suspended from the lower surface of the front end of the injection cylinder, the front ends of the left and right side walls 25 suspended from the left and right sides of the top plate are connected to the left and right sides of the upper part of the trigger 24, and the lower ends of the left and right side walls 25 are connected to the openings 12. It fits inside so that it can move up and down. In addition,
The lower end of the stem fitting cylinder 21 is formed in a large-diameter portion through a downward step, and the lower portion of the large-diameter portion is formed in a tapered portion 21a having a large diameter. To the inner surface of the large-diameter portion above the portion. At this time, the stem fitting cylinder 21 is slightly inclined with respect to the ejection stem 5.

The rear half of the top plate 22 is inclined obliquely downward and rearward, and an arc-shaped engaging projection 26a is formed on the outer surface of the lower end portion of the hanging plate 26 hanging from the rear inner surface of the left and right side walls 25. On the other hand, a semicircular arc-shaped engaging concave portion 27 which curves upward is formed in both the rear left and right portions of the peripheral wall 11, and the engaging protrusion 26a is rotatably engaged with the concave portion, and the rear wall of the peripheral wall is formed. An engaging plate 28 projects from the inner surface, and the rear end of the top plate 22 is engaged with the upper surface of the engaging plate.

Further, a lower portion of an unauthorized use prevention plate 31 is provided between the upper ends of the left and right inner surfaces of the front end of the opening 12 via a breakable thin piece 30, and a notch 32 is formed at the lower end of the left and right side walls 25. After forming the notch, the unauthorized use prevention plate 3
Fit to 1. A nozzle 33 has a rear portion fitted to the front inner surface of the injection cylinder 23.

Next, the operation of the present embodiment will be described.
As shown in FIGS. 1 and 2, when the trigger 24 is pulled rearward before the unauthorized use prevention plate 31 is removed, the stem fitting cylinder 21 is inclined rearward with respect to the ejection stem 5. Therefore, the left and right side walls 25 are also displaced forward while descending. For this reason, the thin piece 30 is easily broken.

On the other hand, the stem fitting cylinder 21 is lowered by the pulling of the trigger 24, but the ejecting stem 5 may be pushed down until the downward step portion of the large diameter portion contacts the upper end surface of the ejecting stem 5. Absent. In other words, the thin piece 30
No mist or the like will be ejected from the nozzle until the is broken.

When the trigger 24 is released after the ejection, the spray member 20 with the trigger swings upward and returns to the original position. At this time, the rear end of the top plate 22 is engaged with the upper surface of the engagement plate 28. It does not rise too far beyond its original position.

[0014]

According to the present invention, since the trigger is provided, it is possible to eject a mist or the like from the injection cylinder by pulling the trigger rearward. The spraying operation becomes easy. Further, since the unauthorized use prevention plate is provided, it is possible to prevent the trigger from being pulled in the distribution channel, and it is possible to visually recognize the fact of use by the trigger being drawn.
