Description

[Detailed Description of the Invention] This invention relates to a safety device for a sprayer, which is formed so that the head of the sprayer can be manually pressed down to spray the seasoning from a container containing a seasoning called, for example, Tabasco.

With conventional sprays of this type, even if your hand accidentally touches the spray, the liquid will be sprayed out, and depending on the nature of the liquid, there is a risk of personal injury.

Therefore, this idea involves pivoting a shield to the head of a sprayer with a liquid spout drilled on the side so that its rotational axis is oblique to the vertical axis of the head. If the center of gravity of the body is deviated from the center of rotation and the liquid container is placed upright, the shield will cover the spout and the liquid will not scatter even if your hand accidentally touches the spray. In addition, when the container is tilted and the jet port is directed downward to perform jetting, the above-mentioned inconvenience is solved by preventing the jetting from being obstructed by a shield.

The invention will be explained below based on an example in which this invention is applied to a Tabasco container with a spray.
The head 3 of the sprayer 1 is supported by a cylindrical body 5 in which a piston 4 is fitted, and the piston 4 is attached to the end of a cylinder 7 fixed to the container 2 via a spring 6. It is supported by

The diameter of this cylinder 7 is formed in two stages, with the piston 4 fitting into the lower small diameter portion 7a and the upper large diameter portion 7b.
A large end portion 5a at the lower end of the cylindrical body 5 is slidably fitted into the cylindrical body 5.

Further, the lower end of the cylinder 7 is connected to a flexible tube 8 inserted into the container 2.
is connected to.

A liquid passage 4a is bored in the center of the lower end of the piston 4, and the upper end of this passage 4a is connected to the large diameter portion 7b of the cylinder 7.
This hole 4b is covered with a flexible valve 9 fitted onto the piston 4, and opens when the hydraulic pressure in the passage 4a increases, and vice versa when the hydraulic pressure decreases. It is formed to close.

Next, the head 3 of the spray 1 has a cylindrical shape, and a liquid spout 10 is provided on the side.
a, and the liquid reservoir 3a is in communication with the container 2.

That is, the liquid reservoir 3a communicates with the large diameter portion 7b of the cylinder 7 through the gap between the cylindrical body 5 and the piston 4.

Next, there is a spout 1 on the top surface of the head 3 relative to the vertical axis of the head 3.
The bearing seat 11 is provided at a predetermined angle of inclination so that the zero side is higher,
A cap-shaped shield 12 is rotatably supported by the head 3 via a bearing 11a mounted on the bearing seat 11.

When the container 2 is stood upright, the shield 12 whose center of gravity is offset from the center of rotation rotates under its own weight to cover the spout 10, and when the container 2 is tilted, the spout 10 is closed. When the liquid is jetted downward, the opening portion 12a provided in the shield 12 overlaps with the spout 10, so that the jetting of the liquid is not obstructed.

That is, as shown in FIG. 3A, assuming that the shield 12 is rotatable around two rotation axes at an inclination angle α with respect to the vertical axis of the container 2, the distance between the center of gravity G of the shield 12 and the two rotation axes is r
If, when the container is erected, the center of gravity G is separated by an angle θ from the plane including the rotation axes and the highest and lowest positions of the shield 12, as shown in the opening of FIG. Since a torque of (Wr sin a sin θ) due to its own weight W is generated counterclockwise in FIG. 3, the opening portion 12a of the shield 12
The ejection port 10 is moved to the lowest position of No. 2 and is covered by the shield 12.

Also, if the container 2 is tilted so that the spout 10 faces downward,
Since the shield 12 generates a torque in the opposite direction clockwise in the figure due to its own weight, the opening portion 12a moves and overlaps the spout 10, and the shield 12 does not interfere with the injection of liquid. There isn't.

By the way, since the function of the shielding body 12 is as described above, the shielding body 12 does not necessarily have to be formed into a cap shape as in the above embodiment, but in other words, it is of a size or shape that can cover the spout 10. It may be.

In order to spray the liquid, the head 3, which has been lifted upward as shown in FIG. 1 by the action of the spring 6, may be pushed from above against the spring 6 to the state shown in FIG. 2.

That is, since the pressure inside the container 2 is increased by the piston 4 descending within the small diameter portion 7a of the syringe 7, the liquid lifts the valve 9 and flows out into the large diameter portion 7b via the hole 4b.

However, since the volume of the large-diameter portion 7b is also reduced due to the descent of the large end 5a, the pressurized liquid escapes into the liquid reservoir 3a through the gap between the cylindrical body 5 and the piston 4 and exits from the spout 10. It gushes out.

Also, if you let go of the head 3, the head 3 will be moved to the first position by the spring 6.
The situation returns to the one shown in the figure, but in this case, the liquid in the container 2 is sucked up by the piston 4 rising inside the small diameter portion 7a, and the liquid is prepared for injection when the head 3 is pushed down again. It becomes.

The spray safety device according to this invention is constructed as described above, so even if the liquid is accidentally sprayed while the container is in an upright position, there is no risk that the liquid will scatter and stain clothes, etc. There isn't.

In particular, with the spout facing upward, even if you accidentally spray Tabasco, for example, there is no risk of the liquid getting into your eyes and causing an unexpected situation.

Moreover, if the spout is directed downward in order to spray the liquid, the shield will automatically occupy a position where it will not interfere with the spray.

Further, since this spray safety device simply attaches a rotatable shield to the spray, it has a simple structure and has many remarkable effects such as no risk of failure.
