Description

[Detailed description of the invention] This invention removably fits the inner diameter part to the outer diameter part of the valve stem between the lower surface of the injection button and the upper surface of the container cap, making it impossible to press down the injection button when installed. It is about stoppa.

The purpose of this invention is to form the stopper into a segmented piece shape, change the stroke as appropriate within a predetermined pump stroke range, and enable the user to set the desired spray volume for convenient use. shall be.

Hereinafter, the drawings showing the embodiments of the present invention will be described. Fig. 1 is a side view of the pump component, showing a state in which a stopper is attached. 2 is a valve barrel whose upper end is fitted and fixed to the inner diameter of the screw cap 1 and hangs down; a piston can slide up and down on the inner diameter of the valve barrel; 3 is the A valve rod with a piston at its lower end, which is slidably supported by a spring and projects a certain distance from the upper end surface 1a of the screw cap 1; 4 is an injection button fitted and fixed to the upper end of the valve rod 3; 5 is the lower surface of the injection button 4; 4a and screw cap 1
The stopper has a height that is approximately the same as the distance from the upper end surface 1a of the stopper.

The stopper 5 is formed so that the inner diameter part 7 of the bifurcated elastic part 6 is substantially the same as the outer diameter part of the valve stem 3, and is detachably attached to the valve stem 3 using the opposing interval between the ends of the bifurcated elastic part 6 as a fitting opening. In addition, the stopper 5 is formed into a divided piece shape with an upper portion 5a and a lower portion 5b that approximately bisect the height dimension, and has the same shape.
An appropriate number of small connecting pieces 9 are arranged to form the same body. The small connecting piece 9 is provided with a small cross-sectional shape to facilitate separation. Reference numeral 10 denotes a handle portion that protrudes from the outer periphery of the bifurcated elastic portion 6 as one body.

When the stopper 5 constructed in this manner is attached to the outer diameter of the valve stem 3, the upper surface of the upper portion 5a comes into contact with the lower surface of the injection button 4, and the lower surface of the lower portion 5b comes into contact with the upper surface 1a of the screw cap 1 and is pressed. The downward stroke interval is filled to make it impossible to press down the injection button 4. When removed from the valve stem 3, the stopper is released and the button can be pressed down, but the customer may desire a small amount of spray. In this case, since the pressing down operation is performed intuitively within a small stroke range, it is not constant, and furthermore, the spray may be defective, which is inconvenient.

According to the present invention, one of the small connecting pieces 9 can be cut and used as a stopper, and even in the case of fine spraying, a constant amount can always be sprayed, and the spraying can be carried out reliably and smoothly.

A connecting ring 11 is integrally formed with the upper portion 5a or the lower portion 5b, and the valve rod 3 can be inserted into the ring hole 11a, so that the separated stopper parts can always be connected integrally. This prevents powder loss and allows the stopper to be reliably set when not in use.
Further, the height dimensions of the upper portion 5a and the lower portion 5b may be arbitrarily changed in design, and may also be formed into two or more divided pieces, and in this case as well, they are integrally formed with small connecting pieces.

As described above, in the present invention, the stopper is integrally molded with a split piece-like composite body through a small connecting piece, and the small connecting piece can be separated, allowing the user to perform fine spraying as desired. It is a convenient stopper that is always constant, reliable, and smooth, and easy to use.
