Description

[Detailed description of the invention] (Purpose of the invention) This invention relates to a guard cap that protects the head of an aerosol injection container, but does not require the trouble of removing it each time an injection operation is performed. It is completely protected by being hidden inside the guard cap, and when activated, the nozzle appears on the outside, making it possible to spray only at that time, and preventing accidental spraying even if the operating part is touched inadvertently. Its purpose is to provide what is possible.

Since the push button with the injection nozzle and the valve stem of an aerosol injection container are exposed at the head of the container, these parts need to be protected from the outside world when not in use, so they are generally removable. A protective cap is included. However, such a protective cap has the inconvenience of having to be removed each time an injection operation is performed.
They tend to get lost because people forget to re-crown them after use. Therefore, for items that are used frequently on a daily basis, caps that do not need to be removed every time, that is, the aforementioned guard caps, are increasingly being installed. However, conventional guard caps cannot cover the injection nozzle, and
Even if there is a push button for operation, the protection of the nozzle and operation parts is insufficient, such as spraying when touched inadvertently. Therefore, this invention aims to provide a means that can eliminate such drawbacks of the conventional guard cap.

(Structure of the invention) This invention will be explained below with reference to the illustrated embodiment.The guard cap/button assembly according to this invention includes a guard cap 2 and a lever button 3.
It is made up of. The guard cap 2 has a pair of support walls 23, 23 formed opposite to each other on the top of a cylindrical wall 22 which has a hook 21 for engaging and fixing the aerosol injection container to the mountain cap 11.
The guide grooves 24, 24 described below are bored in the.

The lever button 3 described above includes a lever body 30 in which a recess 31 is formed approximately in the center, and a recess 3.
It consists of a core 36 fitted into the core 1. A through hole 34 for fixing the nozzle 33 is bored in the front part of the bottom wall 32 of the recess 31 of the lever body 30, while a through hole 34 for fixing the nozzle 33 is bored in the rear part of the bottom wall 32 for engaging the top end of the valve stem 12 of the aerosol injection container. A through hole 38 is bored. Further, a support shaft 37 is provided on the side surface of the intermediate portion of the lever body 30.
37 are provided.

A long groove 35 is bored in the bottom surface of the core 36, and the long groove 35 is provided corresponding to the length from the through hole 34 to the through hole 38.

The lever button 3 is connected to the guide grooves 24, 24 and the support shaft 3.
The support walls 23, 23 are supported by a pivot support consisting of 7, 37.
The front end is supported by the cylinder wall 22 as shown in FIG.
It has a movable range from a horizontal position where it engages the top edge of the body to a rearward tilted position shown in FIG.

The lever button 3 is also located in a position where the bottom wall 32 of the recess 31 engages the top end of the valve stem 2 when the guard cap 2 is fixed to the mountain cap 11, as shown in FIGS. It is in.

As described above, the guide grooves 24, 24 are
Together with the support shafts 37, 37, the support shafts 37, 37 constitute a pivot support for the lever button 3, and at the same time, the support shafts 37, 37 are formed so as to be able to be guided downward when the lever button 3 is in a rearward tilted position.

In the illustrated embodiment, the core 36 is molded as a relatively thin shell for convenience of manufacture, so a cover plate 39 is provided to cover the internal void.

That is, since this invention is constructed as described above, the guard cap 2 is used by being engaged and fixed to the mountain cap 11 by the hook 21, as shown in FIGS. 1 and 2. guard cap 2
A pair of support walls 23, 23 are formed opposite to each other at the top of the cylindrical wall 22, and a lever button 3 is pivotally supported between the support walls 23, 23. The lever button 3 is shown in FIG. As shown, the front end has a movable range from a horizontal position where it engages with the top edge of the cylinder wall 22 to a rearward tilted position as shown in FIG.
is fixed to a through hole 34 bored in the front part of the bottom wall 32 of the recess 31 provided in the middle part of the lever body 30, so that the nozzle 33 is not exposed when the lever button 3 is in the horizontal position. It is located inside the cylindrical wall 22 of the guard cap and the front wall of the lever body 30, and is therefore protected from external forces and dust.

Next, in the backward tilting position of the lever button 3, as shown in FIG. At the same time that the nozzle 33 fixed to the bottom wall 32 is exposed, the position of the top end of the valve stem 12 that is engaged with the bottom wall 32 moves to the position of the through hole 38 bored in the rear part of the bottom wall 32, and the through hole 38. A long groove 35 is bored in the bottom of the core 36 fitted in the recess 31, and this long groove 35 corresponds between the through hole 34 and the through hole 38. It cooperates with the valve stem 12 to form a passage from the top end of the valve stem 12 to the nozzle 33. On the other hand, the lever button 3 has a pair of support shafts 37 bored on the side of the lever body 30.
37 and the guide groove 2 bored in the support walls 23, 23.
4, 24, this guide groove 24,
24 is the support shaft 3 when the lever button 3 is in the backward tilted position.
7, 37 are formed so that they can be guided downward, so when the lever button 3, which is in the backward tilted position as shown in FIG. , Therefore, the valve stem 12 engaged with the through hole 38 is pushed down, and the injection liquid is discharged through the valve stem 12, and the elongated groove 3
5 and is injected from the nozzle 33.
When the pressure on the lever button 3 is released, the lever button 3 also rises in its rearward tilted position due to the restoring force of the valve stem 12 itself, and injection stops. Therefore, if you press the front part of lever button 3 with finger pressure, lever button 3
returns to the horizontal position again, and the nozzle 33 is protected by the lever button 3 and guard cap 2 as shown in FIG. Although not shown, the lever button 3 is designed to automatically return to the horizontal position by interposing a push-up spring between the rear part of the lever button 3 and the mountain cap 11. It is also possible.

(Effect of the invention) That is, according to this invention, in the aerosol injection container, the nozzle 33 is hidden inside the guard cap 2 when no injection is required and the nozzle 33 is hidden inside the guard cap 2. On the other hand, the lever button 3 cannot be lowered until it is tilted backwards, and the injection valve will not open. There is no risk of liquid leaking.
