Abstract

PURPOSE:To obtain a touch pump where impregnation of liquid into absorbent is facilitated, by pressurizing/depressurizing a feed water valve formed into a cup shape with material having high recovery performance such as rubber thereby sucking/pumping liquid from in a container. CONSTITUTION:When taking out liquid from a container containing liquid, a special pump is fixed on the container then a feed water valve 1 made of rubber and equipped with a cup-shaped valve section 1a is pressed from above to push out air from the valve through an opening for passing water. While when releasing press operation, the cut section 1b will close first to recover the valve section 1a under this state, but through suction force a check ball 8 is sucked up to the lower face of a ball stopper 7 to open a water pass hole 5 in a suction pipe holder 3 thus to suck up liquid in the container through a pipe 9 into the valve section 1a. Then liquid is led to the outside through the cutting section 1b and impregnated into an absorbent.

Description

[Detailed Description of the Invention] (Technical Scope) The present invention has a simple structure and simple operation to suck up liquid and guide it to the outside when a container equipped with a special pump is tipped over. Regarding special pumps that prevent liquid from leaking to the outside.

(Purpose) The present invention has a short stroke, soft touch, and simple □ structure, so it is possible to collect an appropriate amount of liquid with simple operation with one hand.

In addition, the container with this special pump installed has a structure that prevents the liquid inside the container from leaking out when the container is tipped over, and when used in combination with the container, cosmetics, disinfectants, etc. can be easily, economically, and sanitarily dispensed. This makes it possible to use it for practical purposes.

(Prior Art) Currently, in most cases when cosmetics, disinfectants, etc. are used, the container is held and absorbent cotton or the like is soaked in the solution. in this case,
Be sure to pour it into the mouth of a cotton-wool container and use the container upside down. Therefore, when collecting liquid from a container, it is necessary to use both hands, which is very inconvenient when you are in a hurry or when you have to hold something with one hand.

Furthermore, when the container is tilted and dropped when carrying the container, the liquid inside often spills out and stains clothes, etc. Additionally, spray pumps have many drawbacks, such as being difficult to use due to their large strokes, scattering in all directions, and being very uneconomical as the appropriate amount cannot be dispensed.

(Solution Means) In order to solve this problem, the present invention provides a water supply valve made of highly elastic material such as rubber, so that water can flow even if the top surface of the water supply valve is directly pressed with one hand without using both hands. In addition to making it possible to collect the appropriate amount of liquid without blocking the notch, the top surface of the water supply valve is designed to prevent the liquid inside the container from leaking out when the container with this special pump installed is tilted or tipped over. The water passage notch and intake valve have a structure with the following functions.

In other words, due to the appropriate hardness and elasticity of the material of the water supply valve and its bowl-shaped shape, the water passage notch on the top surface of the water supply valve opens only during the suppression operation, and is completely closed when no suppression operation is applied. It has a close contact function.

The intake valve part is formed with a bag-shaped protrusion that points toward the inside of the container attached to this special pump, and a notch is provided at the tip of the bag-like protrusion, and the appropriate hardness and elasticity of the material of the intake valve part make it possible to prevent the outside of the container. However, it opens against internal pressure.

The container has a function of opening and retracting against pressure from inside the container to the outside (Example) Examples of the present invention will be described below with reference to the drawings.

(1) is a water supply valve made of, for example, rubber or the like having appropriate elasticity. The water supply valve (1) has a groove (2) in the lower side of the side into which the mouth of the container to which the special pump is attached is fitted, and a bowl-shaped valve part (1a) in the center; 1a
) is provided with a water passage notch (lb)' in the center. Due to the appropriate hardness and elasticity of the material of the water supply valve (1) and its bowl-shaped shape, this water passage notch (lb) opens only during pressing operation, and when no pressing operation is applied. Contains a function that allows complete contact when the suppression operation is released.

Around the notch (1b), when the valve part (1a) of the water supply valve (1) is pressed directly with a finger, etc., the pressure of the finger or the like is applied to the water supply valve (1).
) with a semicircular cross section so that the water does not directly enter the water passage notch (1b) of the valve part (1a), and so that the water passage notch (1b) is not blocked by fingers, etc. Protrusion (IC) t - Formed in an annular shape, with some parts without protrusion (IC).

A former intake valve part (1d) which is integrally formed around the bowl-shaped valve part (1&) is formed with a bag-shaped protrusion toward the interior of the lower container, and a notch (1e) is provided in the protrusion. For,
It has the function of opening against pressure from the outside of the container to the inside, but not opening against pressure (water pressure) from inside the container to the outside. This intake valve portion (ld) may not be formed integrally with the water supply valve (1), but may be provided separately.

The lower part of the water supply valve (1) is provided with an opening (4) into which the water suction pipe holder (3) is inserted, and the diameter of this opening (4) is formed to be slightly smaller than that of the water suction pipe holder (3). This prevents liquid from leaking or dripping from the fitting portion of the water supply valve (1) and the water suction pipe holder (3).

A water passage hole (5) is provided in the center of the water absorption pipe holder (3), and a ball holder (7) containing several water passage holes (6) is inserted into the upper part of the water passage hole (5). Ball (8)
to be placed.

There is a water absorption pipe (9) at the bottom of the water absorption pipe holder (3).
t-insert.

Next, the operation according to FIGS. 2 to 4 will be explained.

Figure 2 shows the state before the suppression operation, and when sucking up liquid from the container to which this special bong 1 is attached and taking it out to the outside,
By performing the suppression operation in the direction of the arrow as shown in Fig. 3, the water supply valve (1) is compressed into the shape shown in Fig. 3, and the water passage notch (1b) provided on the upper surface of the water supply valve (1) ) opens, the air inside the water supply valve (1) is pushed out.

At this time, the check ball (8) closes the water passage hole (5) of the water suction pipe holder (3) as shown in FIG. 3, as in FIG. 2 without any operation.

Next, by releasing the pressing operation, the water passage notch (1b) of the water supply valve (1) closes first, as shown in Fig. 4, and the water supply valve (1) closes first.
1) begins to restore its original position, and the suction force at that time causes the non-return ball (8) to be sucked upward to the bottom surface of the ball holder (7), opening the water passage hole (5) of the water suction pipe holder (3). Open,
The liquid in the container passes through the water suction pipe (9) and is sucked upward from the check ball (8).

The liquid thus sucked up is stored inside the water supply valve (1). At this time, as the amount of liquid in the container decreases, the air pressure in the container decreases, and air pressure acts on the intake valve part (1d) provided at the bottom of the water supply valve (1) from the outside of the container to the inside.
The notch (1e) of the intake valve portion (1d) opens and air flows into the container, thereby assisting the restoring force of the water supply valve (1), allowing quick restoration.

By repeating the above operation again), the liquid in the container to which this special pump is attached is guided to the outside through the water passage notch (1b) of the water supply valve (1), and then transferred to absorbent cotton, tissue paper, etc. It can be easily used by impregnating the liquid with metal.

(Effects) By attaching the special pump of the present invention to a container, it has a short stroke and a soft touch, and because it has a simple structure, you can easily pump the liquid in the container with one hand without using both hands. It is possible to collect an appropriate amount of liquid, and even if the entire container is knocked over or knocked over when carrying it, the liquid inside the container will not leak out.
This invention has excellent practicality, as it can be used in a wide range of cosmetics, disinfectants, etc., and the liquid can be used simply, safely, economically, and hygienically.
