Description

The present invention relates to a pump head that is fitted in a bottle that stores a disinfectant solution, has a nozzle that discharges the disinfectant solution to the fingers by pushing, and can be used hygienically.

With the spread of the new coronavirus infection, it is possible to install disinfectant bottles with pump heads at the entrances and exits of buildings such as companies, stores, public facilities, etc., and disinfect hands when entering and exiting buildings and rooms. It has become a habit.

As shown in Non-Patent Document 1, the pump head of the conventional disinfectant solution bottle is fitted in a bottle for storing the disinfectant solution, and the disinfectant solution is discharged from the nozzle by pushing the top push area.

However, the disinfectant bottle installed at the doorway where an unspecified number of people enter and exit is touched by a hand that may be contaminated by an unspecified person before disinfecting the hands. Therefore, even though the fingers are disinfected after pushing the push area, there are a certain number of people who do not use the push area because they feel that the push area is not hygienic and do not want to touch it.

Therefore, an object of the present invention is to provide a pump head that is fitted in a bottle that stores a disinfectant solution and is provided with a nozzle that discharges the disinfectant solution to the fingers by pushing, and can be used hygienically.

In order to solve the above problems, the present invention
(1)
A head portion having a push area that is vertically movable and pushed to a bottle that stores the disinfectant solution, a nozzle that discharges the disinfectant solution by the push, and a nozzle that sends the disinfectant solution to the nozzle each time the disinfectant solution is pushed. A pump head with a pump
The head part

( 3 )
The pump head according to (1 ) or ( 2 ), wherein the mesh cover is removable.
(4)
In the case of a cloth or a soft porous, the mesh cover is sandwiched between the cap and the wall body, and is provided with a support for holding the shape of the mesh cover ( 1 ) to ( 3 ) . The pump head according to any one.
And said.

Since the present invention has the above configuration, the disinfectant solution is leaked, moistened, and automatically disinfected each time the push area of the pump head is pushed, and the push area is prevented from drying by interposing a sponge. The push area can be kept moist and disinfected at all times. Therefore, the pump head can be used hygienically, and it is possible to prevent unsterilization of a person who avoids disinfection of fingers due to unsanitary conditions and suppress the spread of infectious diseases.

A spray-type disinfectant device that uses sensor detection is also available, but it is expensive and the installation location is limited when a commercial power source is required. On the other hand, according to the present invention, it is inexpensive, does not require a power source, has no limitation on the installation location due to a limitation on the power supply, and can be placed anywhere.

FIG. 1 is a schematic perspective view of a pump head according to the present invention. FIG. 2 is a side longitudinal sectional view of a part of the pump head of the present invention. FIG. 3 is an exploded side view of a part of the pump head according to the present invention. FIG. 4 is a cross-sectional view showing a state change when the mesh cover (push area) is pushed. FIG. 4 (A) shows the state during standby for use, and FIG. 4 (B) shows the state during push.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The present invention is not limited to the following examples.

As shown in FIG. 1-3, the pump head 1 of the present invention is attached to a bottle 7 for storing the disinfectant solution 8 so as to be vertically movable via a lid 6, and is pushed by a push area (here, a mesh cover). It is provided with a head portion 2 having 2 g), a nozzle 3 for discharging the disinfectant solution 8 by pushing, and a pump 4 for sending the disinfectant solution 8 to the nozzle 3 each time the push is performed. Leaks and push areas are also disinfected.

Leakage of the disinfectant solution 8 is performed, for example, by branching the disinfectant solution 8 sent to the nozzle 3. On the other hand, other tanks may be prepared for dispensing to the push area. If a bottle for storing the disinfectant solution 8 for disinfecting the push area is shared with the fingers, it can be provided with a simple structure and low cost.

The bottle 7 is provided with an inner pipe 5 through which the internal disinfectant liquid 8 is passed, and may be a conventional one. The disinfectant solution 8 may also be one that has been conventionally used. Further, the pump 4 communicates with the inner pipe 5 and the vertical pipe 2a described later, and in response to the push of the push area (head portion 2 (mesh cover 2 g)) with the fingers, the disinfectant solution 8 inside the bottle 7 is inside. If the pump can be sent from the pipe 5 to the nozzle 3 through the vertical pipe 2a, the principle is not particularly limited, such as pushing out by air pressure or suction under reduced pressure, and a conventional pump can be used.

The head portion 2 stands upright in a vertical pipe 2a that communicates with the disinfectant liquid 8 in the bottle 7 via a pump 4, a hole 2b formed in the main body 2m that communicates with the vertical pipe 2a, and a main body 2m on the outer periphery of the hole 2b. On the check valve 2e and the check valve 2e, which are placed on the bottom of the space 2d surrounded by the wall body 2c, the wall body 2c and the main body 2m, and prevent the disinfectant solution 8 from leaking and flowing back into the vertical pipe 2a. A sponge 2f to be placed, a mesh cover 2g (push area) arranged above the sponge 2f, and a cap 2h having a hole 2i on the upper surface to prevent the mesh cover 2g from falling off and being fitted to the wall body 2c. Consists of.

The sponge 2f has a function of holding the leaked disinfectant liquid 8 and pressing the check valve 2e. By providing the check valve 2e, the sponge 2f pushes the valve of the check valve 2e even if the push is released, and the communication between the space 2d in which the sponge 2f is arranged and the disinfectant solution 8 sent to the nozzle 3 is cut off. Therefore, there is no backflow from the space 2d to the disinfectant solution 8 on the nozzle 3 side, and there is no reduction in volatilization of the disinfectant solution 8 on the bottle 7 side. Here, the sponge 2f is a mass of a porous soft substance having innumerable fine holes inside, and includes, for example, an aggregate of cloth.

As shown in FIG. 3, the mesh cover 2g is removable. Further, in the case of a cloth or a soft porous, the mesh cover 2g is sandwiched between the edge bottom of the cap 2h and the flat surface of the wall body 2c, and includes a support 2n that holds the shape of the mesh cover 2g.

Here, the mesh cover 2g is sandwiched between the cap 2h and the wall body 2c, but if the mesh cover 2g is a cured product, it is placed on the sponge 2f without interposing the support 2n and without being sandwiched, and is placed on the sponge 2f up and down. The head portion 2 may be moved up and down while moving and pressing the sponge 2f. By pushing and lowering the mesh cover 2g, the sponge 2f is compressed, and the disinfectant solution 8 filled in the sponge 2f oozes out, moistening the mesh cover 2g and the fingers with the disinfectant solution 8 more effectively. They can be sterilized.

As shown in FIG. 4, the mesh cover 2g is a push area, and the head portion 2 moves up and down by pushing the mesh cover 2g, and the disinfectant liquid 8 is sent to the nozzle 3 as it is discharged from the nozzle 3. The liquid 8 leaks from the hole 2b to the sponge 2f, and the push area is disinfected.

The wall body 2c is a bank that does not leak the disinfectant liquid 8 leaked to the sponge 2f (space 2d). The fitting of the wall body 2c and the cap 2h can be exemplified by screwing with the screw portions 2j and 2k, but in addition, a detachable method can be adopted in which the sponge 2f does not fall off.

The diameter of the hole 2b may be appropriately determined so that an appropriate amount of the disinfectant liquid 8 leaks from the nozzle 3 of the disinfectant liquid 8 to the sponge 2f according to the discharge pressure and the characteristics of the check valve 2e.
