Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cap for an atomizer, and particularly to a so-called one-touch cap for an atomizer, which allows spraying to be performed while being fixed to the atomizer.

One-touch caps are easy to use because they do not require the trouble of removing the cap for each operation, unlike removable so-called overcaps, but they are considerably more expensive to manufacture than overcaps. However, this had the disadvantage of being relatively expensive because it was a fixed type and had to be discarded together with the sprayer.

The present invention attempts to solve this problem of high cost by improving the structure of the one-touch cap that is fixed to the sprayer so that it can be removed from the sprayer with a simple manual operation, recovered, and reused. It is.

Embodiments of the present invention will be described below based on the accompanying drawings.

Figures 1-3 schematically illustrate an embodiment of the invention, with the injector pushbutton omitted.

As is clear from FIGS. 1 to 3, the one-touch cap of the present invention comprises an outer cylinder 1 and an inner cylinder 2, and like the conventional product, the lower end of the outer cylinder 1 is connected to the upper end of the body a of the sprayer. The lower end of the inner cylinder 2 is fitted into the tightening part b and the upper tightening part d of the upper end of the head c of the sprayer, and furthermore, in this fitted state, the lower end of the inner cylinder 2 protrudes inward. A claw portion 3 is engaged with the lower edge of the upper winding portion d.

In the present invention, in this type of one-touch cap, the claw portions 3 are formed at two positions on the left and right so as to sandwich the center of the inner cylinder 2, and on the other hand, approximately from the third position of the claw portions. Pressing operation parts 4, 4 are formed at two places on the front and back of the lower part of the outer circumferential surface of the outer part 2 so as to be offset by 90 degrees, and furthermore, the inner cylinder 2 and the outer cylinder 2' are connected to each other by pressing the pressing operation parts 4, 4 into the outer cylinder. When the lower part of 1 is pressed inward, the inner cylinder 2 is deformed by this pressing force, and the claws 3, 3 at the lower end of the inner cylinder 2 are moved through the bridges 5, 5 so that they become freer than the upper winding tightening part d. connected.
As is clear from FIGS. 2 and 3, the bridges 5, 5 connect the inner and outer cylinders 1, 2 over almost their entire upper and lower widths at positions that coincide with the pressing operation parts 4, 4. There is.

As shown in FIG. 1, when the cap of the present invention is attached to the injector, the claws 3, 3 at the lower end of the inner cylinder 2 are attached to the lower edge of the upper winding tightening part d at two places on the left and right. Since the cap is fixed to the atomizer, the cap is fixed stably and reliably due to the locking effect of the claws 3, 3, and will not come off from the atomizer.

As shown by the arrow 6 in FIGS. 2 and 3, when the pressing operation parts 4, 4 at the lower part of the outer peripheral surface of the outer cylinder 1 are pressed inward, this pressing force is applied to the inner cylinder through the bridges 5, 5.
As a result, the inner cylinder 2 is deformed to become slightly laterally elongated, and this deformation causes the claws 3, 3 to
It opens in the direction of arrow 7 in the figure, becomes free from the upper winding part d, and becomes removable. By removing and recovering the cap in this way,
Can be reused as a cap for a new sprayer. In order to facilitate deformation of the inner cylinder 2 at the pressing operation part, it is desirable that the inner cylinder 2 be loosely fitted to the upper winding tightening part d so that there is some clearance.

Figures 4 to 6 show other examples of implementing the present invention. In this example, the cap includes the inner and outer cylinders 1 and 2, and
It has an innermost cylinder 2a whose lower end is slightly higher than that of the inner cylinder 2, and a push button e is built into this innermost cylinder 2a. The innermost cylinder 2a, the inner cylinder 2, and the outer cylinder 1 are formed with vertically elongated openings 2a', 2', and 1' for inserting the injection cylinder e' of the push button e. A vertical wall 10 is provided so as to be closed. By these vertical walls 10, 10, the equal cylinder 2
a, 2 and 1 are connected together.

In this embodiment, of the claw parts 3, 3, the left claw part 3 in FIG. 4 forms an opening 2' in the inner cylinder 2. Split formation.

The bridges 5, 5 are provided at positions that match the claws 3, 3, and the bridges 5, 5 on the left side in FIG.
In this case, a part of the vertical walls 10, 10 is used. As is clear from FIG. 4, auxiliary bridges 5a can be provided on both sides of the bridge 5.

Further, the inner cylinder 2 has slits 11, 11 extending in the vertical direction at positions substantially coincident with the pressing operation parts 4, 4, and is divided into two parts at the slits 11, 11.

In this embodiment, when the pressing operation parts 4, 4 of the outer cylinder 1 are pressed inward, this pressing causes the bridges 5, 5 to
is pushed outward as shown by arrow 12 in Figure 4,
As a result, the slits 11, 11 of the inner cylinder 2 open and the claws 3, 3 move outward, so that the claws 3, 3 become free from the upper winding portion d (see Fig. 1).
In this way, in this embodiment as well, as in the previous embodiment, the cap can be removed and recovered from the sprayer as required.

In this way, the cap of the present invention is fixed to the sprayer by the locking effect of the claws 3, 3 during normal use, but after using the sprayer, the operating parts 4, 4 can be closed. By pressing it, it can be removed from the sprayer, collected and reused. Therefore, even if the manufacturing cost of the one-touch cap of the present invention is somewhat higher than that of an overcap, it does not become expensive, and its usefulness can be further improved.
