Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a sprayer provided with a stopper for temporarily stopping the ejection of cosmetics, chemicals, and the like.

[Conventional technology]

Conventionally, as an example of this type of structure, for example, a button pressing stopper device for a spray pump described in Japanese Utility Model Laid-Open No. 59-10866 shown in FIG. 4 and an actual development by the applicant of the present invention shown in FIG.
There is a sprayer described in JP-A-60-128758.

The outline of both of these sprayers is a structure for spraying liquid cosmetics or the like by the pump operation by the vertical reciprocating motion of the valve rod 21 by pressing down or spraying the spray button type or trigger type jetting operation member 20, The following means are adopted in order to avoid a situation in which the ejection operation member 20 and the valve rod 21 are ejected by being inadvertently interlocked with each other when the product is conveyed. That is, in the case of FIG. 4, a separately prepared restricting piece 23 is engaged with the valve rod 21 of the portion protruding from the cap 22 on the container body side, and the restricting piece 23 is abutted against the cap 22. Thus, the reciprocating movement of the valve rod 21 is restricted so that the pump operation is not performed.

Further, in the case of FIG. 5, similarly, a single regulating piece 23 is prepared, and the regulating piece 23 is used for the trigger type ejection operating member 20 and the valve rod.
The structure is such that it is inserted into a space V formed by 21 and the sprayer main body 24 to regulate the swinging of the ejection operation member 20.

[Problems to be solved by the invention]

However, in both of these two conventional examples, the restriction piece 23 is removed at the stage of use, but when it is desired to store the sprayer again with the restriction piece 23 deactivated. However, since the restriction piece 23 is a single molded product as described above, there is a problem that it tends to be lost during storage.

The present invention has been made in view of the above conventional problems, and an object of the present invention is to provide a sprayer in which a restriction piece that has been detached and stored cannot be lost.

[Means for solving problems]

The present invention has the following configuration in order to solve the conventional problems and achieve the object.

That is, the trigger type spraying device S is attached to the container body 1. The trigger type spraying device S is (a) a casing 6 fixed to the mouth / neck portion 1a and (b) a central upper end of the casing 6.

And a locking support arm 7 that is integrally molded with the container body 1 to prevent the casing 6 from rotating around the container body 1 by engaging the locking portion 1b in the vicinity of the neck 1a of the container body 1, In a sprayer configured to cause the liquid substance in the container body 1 to be ejected from the nozzle cap 5 by converting the swing of the valve rod 3 into the reciprocating motion of the valve rod 4, a belt-shaped stopper that regulates the swing of the trigger 3. Member 10
Is provided, at one end of the band portion 10a of the stopper member 10,
A locking fixing portion 10c is formed to be clamped and fixed between the rotation stopping support arm 7 and the locking portion 1b, and the trigger 3, the casing 6 and the valve rod 4 are formed at the other end of the band portion 10a. The rotation stop portion 10b is formed so as to be detachably inserted in the space V formed by being surrounded by the above three members.

[Action]

When the swing of the trigger 3 is regulated during product transportation or during storage so as to avoid inadvertent ejection of the liquid substance, when the rotation stopper 10b of the stopper member 10 is inserted into the space V, Since the swing of the trigger 3 about the swing shaft 3a is restricted and the valve rod 4 does not reciprocate in the vertical direction, there is no jetting due to the pump action.

〔Example〕

An embodiment of the atomizer according to the present invention will be described below with reference to the drawings.

1 to 3, a trigger type spraying device S is attached to a container body 1 filled with a liquid substance such as liquid cosmetics via a cap 2. This trigger type spraying device S itself is a well-known technical structure, and a detailed description thereof will be omitted, but this outline is that by swinging the trigger 3 in the direction of arrow A, this swinging causes the valve rod 4 to move up and down in the drawing. Is converted into a reciprocating motion in the direction, and the liquid cosmetic material sucked from the container body 1 is ejected from the nozzle cap 5 at the tip end in a spray state by the pump operation by the reciprocating motion of the valve rod 4.

The casing 6 of the trigger type spraying device S is integrally formed with a rotation stopping support arm 7 which is also a portion for gripping and fixing the entire sprayer at the time of use, and the lowering portion 7a of the rotation stopping support arm 7 is connected to the mouth of the container body 1. By engaging with the locking portion 1b provided near the neck portion 1a, the trigger spraying device S is prevented from rotating with respect to the container body 1.

Further, a valve rod 4 that is reciprocally movable in the vertical direction projects from the upper end of the center of the casing 6. Further, at the rear portion of the casing 6, the rear end of the trigger 3 is provided with a swing shaft 3a.
It is rotatably supported via the trigger 3, and the trigger 3 can swing with respect to the casing 6. This trigger 3
The tip of the finger extends as a finger hook 3b in front of the casing 6, and the middle of the trigger 3 and the middle of the valve rod 4 are connected by a connecting portion 4a, and the valve 3 is rocked by the rocking shaft 3a as a fulcrum.
