Abstract

PROBLEM TO BE SOLVED: To enable a liquid to be easily and reliably poured out with one hand. SOLUTION: A liquid pour-out device allows the liquid in a vessel for housing the liquid to be poured out of a nozzle 13 of a stem 9 by vertical movement of the stem 9 which is assembled to a mouth cylinder of the container 1 and whose lower part has a piston 5 structure. Constitutionally, an upper end of the stem 9 is bent laterally, a pressure plate 11 is placed for installation on the upper end of the stem 9, a lead pipe 12, which is inverted upward to be curved and bent, is assembled to an end of the stem 9, and the nozzle 13 at an end of the lead pipe 12 is opened while pointing approximately in a direction of a center of the pressure plate 11. A back of a person's hand is placed on the pressure plate 11 so as to push down the pressure plate 11. This allows the liquid such as a shampoo, a soap solution, a detergent and cosmetics to be poured out in the center of his/her palm.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid dispensing apparatus to be mounted on a mouthpiece of a container for storing a liquid.

[0002]

2. Description of the Related Art Certain types of containers for storing liquids such as shampoos, detergents, cosmetics, etc. are provided with a mouth of the container so that a predetermined amount of the liquid inside the container can be poured out while the container is standing. A liquid dispensing device called a so-called dispenser is attached to the cylinder.

This liquid dispensing apparatus is disclosed in, for example,
As described in Japanese Patent No. 28496, Japanese Patent Application Laid-Open No. 60-184977, etc., a certain amount of liquid is sucked into a cylinder by a pumping operation of a piston, and the liquid is ejected to the outside from a liquid outlet pipe. is there.

[0004] In this prior art, a liquid outlet tube referred to as a stem penetrates a mouthpiece cap of a container, is assembled so as to be movable up and down, protrudes upward, and has an upper end bent further sideways. With this structure, the upper end of the stem is moved up and down with one hand, and at the same time, the other palm receives the liquid ejected laterally from the nozzle at the tip of the stem.

[0005]

However, in this configuration, since both hands must be used for the liquid dispensing operation as described above, it is difficult to perform the operation with the eyes closed especially during hair washing. There was such an inconvenience. Also,
It is difficult to handle, even for people with one hand that is disabled due to illness or disability.

[0006] In order to solve this inconvenience, a technique has been proposed in which the liquid can be poured out with only one hand. For example, there is a "one-handed hand-pump" described in JP-A-8-100762, JP-A-8-114176, and the like.

In this conventional example, a finger hook is provided on a part of a mouthpiece, and two fingers, for example, a forefinger and a middle finger, of one hand are applied to the lower surface of the finger hook in such a manner as to sandwich a stem. Together with
The thumb of the same hand is applied to the upper end of the stem to push down the stem, and the palm is intended to receive the poured liquid. However, in this configuration, there is a disadvantage that the poured liquid leaks out from between the index finger and the middle finger, and it cannot be operated by a handicapped person with a fist-shaped hand.

Accordingly, the present invention is a liquid dispensing device for a liquid storage container invented in order to solve the above-mentioned conventional dissatisfaction points and to meet the demand, wherein the liquid can be easily and surely dispensed with one hand. The purpose is to be able to.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned conventional problems, the present invention is directed to a method for assembling a liquid in a container by ascending and descending a stem having a piston structure in a lower part, which is mounted on a mouthpiece of a container for storing the liquid. In the liquid dispensing device for ejecting from the nozzle of the stem, the upper end of the stem is bent laterally, and a pressing plate is mounted on the upper end of the stem, and furthermore, the tip of the stem is And a leading pipe which is inverted and bent upward and has a tip nozzle directed and opened substantially toward the center of the pressing plate.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of the present invention will be described. A cap 2 is attached to a mouthpiece of a container 1 for storing a liquid such as shampoo, detergent, cosmetics and the like. The liquid pouring device 3 is assembled.

The liquid dispensing device 3 mainly comprises a cylinder tube 4 and a piston 5 which reciprocally slides inside the cylinder tube 4.

That is, first, the cylinder tube 4 is suspended from the center of the cap 2, the lower end is formed as an inner flange-shaped stepped portion 6, and a lower check valve 7 is provided below the lower portion.
, A suction tube 8 extending to the bottom of the container 1 is provided in communication therewith.

The piston 5 has a hollow tubular stem 9.
An upper check valve 10 is provided at a lower end of the stem 9, and a pressing plate 11 is mounted and fixed in a substantially horizontal posture on an upper end of the stem 9 bent sideways.
The lead-out tube 1 which is turned upside down and bent upward
2 is assembled in such a manner that the tip nozzle 13 is directionally opened substantially toward the center of the pressing plate 11.

In this configuration, when the pressure in the cylinder 4 becomes negative, the lower check valve 7 is sucked and opened to connect the inside of the cylinder 4 with the suction tube 8, and at the same time, the upper check valve 10 close. Conversely, when the pressure in the cylinder cylinder 4 increases,
The lower check valve 7 is pushed and closed, and at the same time, the upper check valve 10 is also pushed and opened to connect the inside of the cylinder tube 4 with the stem 9.

A spring coil 14 is disposed in the cylinder 4 between the step 5 and the lower end of the stem 9 to urge the stem 9 upward. Stand in and wait.

Now, when the back of the hand is placed on the pressing plate 11 to be pressed down, the stem 9 descends against the resilience of the spring coil 14, and the volume in the cylinder cylinder 4 becomes small.

In this state, when the pressing force is released with the hand placed on the pressing plate 11, the stem 9 rises due to the resilience of the spring coil 14, and the inside of the cylinder cylinder 4 is negatively acted upon by the action of the piston 5. As a result, the lower check valve 7 opens and the upper check valve 10 closes, and the liquid in the container 1 is sucked and stored in the cylinder tube 4 from the lower end of the suction tube 8 by a certain amount corresponding to the volume.

Then, when the pressing plate 11 is pushed down again, the volume in the cylinder 4 becomes small and the internal pressure becomes high.
When the lower check valve 7 is closed and the upper check valve 10 is opened, the liquid in the cylinder tube 4 passes through the stem 9 and the outlet pipe 12 and is poured from the tip nozzle 13 to the palm placed on the pressing plate 11. It is issued.

This series of operations for discharging a liquid such as shampoo, soap solution, detergent, cosmetics, etc. from the nozzle 13 to the palm placed on the pressing plate 11 is performed with one hand and the back of the hand is applied to the pressing plate 11. Achieved by simply raising and lowering.

In this manner, a predetermined amount of liquid such as shampoo can be directly dropped on the palm.
Depending on the form of use, a towel or sponge can be held on the palm and dropped directly on it.

[0021]

As described above, according to the liquid dispensing apparatus for a liquid container of the present invention, the liquid such as shampoo, soap liquid, detergent, cosmetics, etc. can be reliably placed in the center of the palm by simple operation of one hand. It can be poured out and has many excellent effects, such as being able to be used reliably even when the eyes are closed or the hand is inconvenient.
