Description

[Detailed description of the invention] <Field of industrial application> The present invention relates to a cap for a tail-type aerosol container that sprays by tilting the stem. This invention relates to caps for tailed aerosol containers.

<Prior art> As shown in Utility Model Application No. 86474/1983, a cap that is attached to a tilt valve type aerosol container and can be used without being removed is a cap that has an operating protrusion on the stem, etc. There was one in which the stem was tilted from the outside of the cap using an operating means to spray from the injection notch in the cap.

<Problems to be solved by the invention> Since the cap of the conventional tail-type aerosol container mentioned above is formed by opening the holding part and the injection part in advance, dust can enter and adhere to the nozzle. etc., it does not function as a complete cap, and since the operating means extends outside the cap so that it can be operated from outside the cap, the operating means may inadvertently touch other objects. However, there has been a problem in that the contents of the aerosol container may be unexpectedly ejected due to contact with the aerosol container.

<Means for solving the problems> In order to solve the above-mentioned conventional problems, the present invention has the following features:
The press-swivel lid, which opens the nozzle and tilts the stem during use, is rotatably attached to the cap body, which is fitted over the nozzle part of the aerosol container, so it can be used with the cap in place. This is how it was done.

<Function> When the side surface of the pressing rotary lid rotatably attached to the cap body is pressed and rotated, the front plate of the pressing rotary lid rotates upward, opening the injection port at the front of the nozzle. At the same time, the stem pushing piece integrally formed on the press-rotating lid pushes the side surface of the stem, causing the contents to be squirted out. Further, after use, when the pressing force is removed, the stem returns to the neutral state by its own restoring force and stops spraying, and at the same time rotates the pressing rotary lid in contact with the stem to return to the closed lid state.

<Example> Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

FIG. 1 shows the cap main body, and the cap main body 1, which has a substantially two-stage cylindrical shape, opens the central part of the top plate 6 and the upper part of the peripheral wall 2 following the top plate 6 by a predetermined width, and sprays water onto the upper part of the peripheral wall 2. A mouth portion 2a and a pushing mouth portion 2b are formed respectively.

Further, the lower ends of the left and right top plates 6, 6 are connected by a connecting plate 3, and the connecting plate 3 has a substantially U-shaped nozzle holder 4 hanging downward, and a shielding plate 5 is connected to the top plate 6 to the rear. They are formed in parallel protrusions.

In addition, 14 is a protrusion for attaching a pressing rotary lid to be described later.

FIG. 2 shows a press-swivel lid 7 that is an integrally molded synthetic resin product, in which a short front plate 7a and a long rear plate 7b are formed before and after a top plate 7c. A stem pushing piece 10 is formed to protrude from the lower end toward the front and parallel to the top plate 7c.
In addition, 10' is a stem engaging groove at the tip of the stem pushing piece 10, and 9 is a stem engagement groove on the left and right sides of the lower surface of the top plate 7c.
A hooking piece 8 provided opposite to 8 indicates an opening of the formwork required during integral molding.

The pressing rotary lid 7 is rotatably attached to the opening of the cap body 1 with the protrusion 14 held between the locking piece 9 and the rear plate 7b, and the shielding plate 5 is fitted into the opening 8. As a result, a cylindrical cap with no irregularities on the surface is completed.

The operation of the cap of the tail-type aerosol container of the present invention having the above configuration will be explained based on the vertical cross-sectional view of the main part shown in FIG. When the rear plate 7b is pressed in the direction of the arrow in the figure, the press-swivel lid 7 moves to the right in the figure around the protrusion 14. Rotate. Injection port 2
The front plate 7a blocking the nozzle 13 is rotated upward to open the front face of the injection port of the nozzle 13, and at the same time, the stem pushing piece 10 tilts the stem 12, so that the contents are ejected.

To stop the ejection, all you have to do is release the finger pushing the rear plate 7b, and the stem returns to the neutral state by its own restoring force and stops the ejection.At the same time, the stem pushing piece that is in contact with the stem In response to the restoring force of the stem, the integral press-rotating lid 7 is rotated to the left in the figure, and the front face plate 7a closes the injection port 2.

Incidentally, since the nozzle 13 is held unrotatably by the substantially U-shaped nozzle holder 4, there is no possibility that the injection port of the nozzle will be misaligned with the opening of the cap.

Furthermore, in this embodiment, the projection is held between the latch piece and the rear plate, and the press-rotating lid is attached to the cap body, but the press-rotating lid is rotatably attached to the cap body. Of course, other methods such as concave-convex fitting may be used.

<Effects of the invention> As described above, the cap of the tailed aerosol container of the present invention can squirt out the contents by simply pressing the side of the aerosol container while the cap is in place. It is extremely convenient to handle as there is no need to return to the container and remove the cap. Since the operating means of the nozzle and stem are not exposed to the outside, there is no possibility of contact with external objects, etc., and therefore there is no possibility that the stem may inadvertently tilt and the contents of the aerosol container may be unexpectedly sprayed out. It is extremely safe. Since the nozzle's injection port is opened and exposed to the outside only when in use, and is normally stored in the cap, there is no possibility that dust or the like will stick to the nozzle and harden, making it difficult to spray. Both the cap body and the press-swivel lid are integrally molded from synthetic resin, and assembly is only a matter of fitting, making assembly and processing easy. It produces an effect that has practical value.
