Description

[Detailed description of the invention] (Scope of technology) The invention is to suck up liquid with a simple operation and guide it to the outside, so that when the container to which this special pump is attached is tilted or knocked down, the liquid does not flow out to the outside. Regarding special pumps.

(Purpose) The present invention has a short stroke, a soft touch, and can easily collect an appropriate amount of liquid with one hand.Moreover, when the container to which this special pump is attached is tilted or tipped over, the liquid inside the container is removed. By having a structure that does not leak outside and using it in combination with a container, cosmetics, disinfectants, etc. can be used easily and economically.

(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 place cotton wool over the mouth of the container and turn 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. Also, if the container is tipped or knocked over when carrying it, the liquid inside may spill out and stain clothes, etc. Furthermore, the spray pump has many disadvantages, such as being difficult to use due to its large stroke, scattering in all directions, and being very uneconomical as the appropriate amount cannot be taken out.

(Solution Means) In order to solve this problem, the present invention provides a water supply valve made of highly elastic material such as rubber, and allows the user to lightly press the top surface of the water supply valve with one hand without using both hands. In addition to making it possible to collect an appropriate amount of liquid, a water passage notch on 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 attached is tilted or knocked down. The intake valve section located at the bottom of the water supply valve has a structure with the following functions.

In other words, the water passage notch on the top surface of the water supply valve opens only during the suppression operation due to the appropriate hardness and elasticity of the material of the water supply valve, and its bowl-shaped shape, so that the suppression operation cannot be interrupted. It has the function of completely adhering.

The intake valve part is integrally formed at the bottom of the water supply valve, and a bag-shaped protrusion is formed toward the inside of the container in which this special pump is attached.A notch is provided at the tip of the bag-shaped protrusion, and the intake valve part is integrally formed. Due to the appropriate hardness and elasticity of the material of the water supply valve, it has the function of opening against pressure from the outside of the container to the inside, but not opening against pressure from inside the container to the outside.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

Reference numeral (1) denotes an operating member, which is made of a highly water-containing material such as a sponge body. (2) is a water supply valve, which is made of, for example, rubber or the like having appropriate elasticity.

A groove (3) is provided on the upper side of the water supply valve (2) into which the mouth of the container to which this special pump is attached is fitted, and a valve R is provided in the center.
The IS (2a) is formed into a bowl shape, and a water passage notch (2b) is provided in the center of the valve part (2a).

Due to the appropriate hardness and elasticity of the material of the water supply valve (2) and its bowl-shaped shape, this water passage notch (2b) opens only during the suppression operation, and remains open when no suppression operation is applied. −
Also, it has the function of completely adhering when the pressing operation is released. Around the notch (21+), press the operating member (
1), a protrusion with a semicircular cross section (2t. ) into a ring shape.

Around the bowl-shaped valve part (2a), four intake valve parts (2(1) are formed with bag-shaped protrusions toward the inside of the container).
Since the protrusion is provided with a notch (::2e), it opens against pressure from outside the container to the inside, but does not open against pressure (water pressure) from inside the container to the outside. has.

The lower part of the water supply valve (2) is provided with an opening (5) into which the water suction pipe holder (4) is inserted, and the diameter of this opening (5) is formed to be slightly smaller than that of the water suction pipe holder (4). This prevents liquid from leaking and falling from the fitting portion of the water supply valve (2) and the water suction pipe holder (4). A water hole (5) is provided in the center of the water absorption pipe holder (4), and several water holes (7) are provided at the top of the water hole (5).
Ball presser foot (8) with 4+? A check ball (9) is placed below it.

There is a water suction pipe θO at the bottom of the water suction pipe holder (4).
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 pump is attached and taking it out to the outside,
As shown in Fig. 3, by performing the suppression operation in the direction of the arrow, the operating member (1) is pushed downward, and the water supply valve (2) is also shaped as shown in Fig. 3. When the water is compressed and the notch (2b) provided on the upper surface of the water supply valve (2) opens, the air inside the water supply valve (2) is pushed out.

At this time, as shown in Figure 3, the check ball (9) is not operated at all as in Figure 2, and the water absorbing vibe holder (4) is
The water hole (6) is blocked.

Next, by releasing the suppression operation, the notch (2b) of the water supply valve (2) closes first, as shown in Figure 4, and the water supply valve (2) begins to restore its original state, and the suction force at that time prevents the non-return. Hall (9)
is sucked upward to the bottom surface of the ball holder (8), opens the water hole (6) of the water absorbing vibrator holder (4), and the liquid in the container passes through the water absorbing vibrator 0 () and passes through the check ball (9). sucked upwards.

The liquid sucked up in this way is stored inside the water supply valve (2). At this time, as the amount of liquid in the container decreases, the air pressure in the container decreases, and each of the four intake valves (2d) provided at the bottom of the water supply valve (2) receives air pressure from the outside of the container to the inside. acts, and the notch (2e) of the intake valve part (2d)
) opens and air flows into the container. This assists the restoring force of the water supply valve (2) and enables quick restoration.

By repeating the above-mentioned operation again, it becomes water-containing.
It can be easily used by absorbing liquid into the soldered operating member (1) and soaking absorbent cotton, tissue paper, etc. in the liquid.

(Effects) By attaching the special pump of the present invention to a container, an appropriate amount of liquid in the container can be easily collected with one hand without using both hands.
Even if the container is tilted or knocked down while carrying, etc., the liquid inside the container will not leak out and can be used for cosmetics, disinfectants, etc. It is an invention with excellent practicality, as it enables the use of concave oni-j, and the liquid can be used easily, safely, and economically.
