Description

  The present invention relates to an invention of a pneumatically extruded liquid container for discharging a liquid such as shampoo from the inside of a container by using air pressure.

  Conventionally, a metal spring is used for a container such as a shampoo, and a pump having a structure in which a liquid outlet goes up and down is used. There was a container that pushed out a liquid such as shampoo from inside the container.

Therefore, there were the following problems.
B. A gap was formed between the movable nozzle and the cap, and sewage and the like penetrated into the container from the gap, resulting in unsanitary conditions.
(B) The area of the hand pushing section at the top of the pump was small and inconvenient.
C Inside the pump, a metal spring is used. To push down the pump, the palm is used, and a certain amount of strong force is required, and it is not easy to press with a light force at the fingertip.
D The nozzle part where the liquid comes out moves up and down, so it was difficult to catch the liquid.
(E) The shape of the nozzle from which the liquid comes out is elongated and sharp, and it is made very hard.Therefore, there is a high risk of damaging the body if it is dropped on the body by mistake or falls over the nozzle. there were.
F) A metal spring, which is different from the material of the main body container, is used inside the pump, so that it was necessary to sort it when recycling.
The present invention has been made to solve the above problems.

As shown in FIG. 2, a discharge hole (11) is provided on the outer surface of the container (1), and a pipe (9) is provided in the container (1). The pipe is provided with a suction hole (10) at the lower end, and the upper end is connected to the discharge hole (11). As shown in FIG. 5, an outflow prevention valve (12) is provided in the discharge hole (11), and a round nozzle (2) is mounted. An elastic flexible (4) is provided on the upper part of the container (1). A push plate (5) is provided on the elastic flexible (4). An injection port (8) is provided on the upper part of the push plate (5), and the lid is covered with a cap (7) with a valve mechanism and a cap (6).
As shown in FIG. 3, the cap with valve mechanism (7) is provided with a support shaft (15), a check valve (16), and an inner air hole (17). A space formed between the cap with valve mechanism (7) and the cap (6) and an outside air hole (18) are provided.
The present invention is a pneumatically extruded container configured as described above.

  By using the present invention, sanitary water does not enter the inside of the container from the upper part of the cap and is sanitary. Even small children, elderly people, and persons with disabilities can easily push down a wide push plate that is easy to push down by simply pushing the fingertip down, and the liquid in the container can be efficiently discharged outside. In particular, since the entire upper surface is a pressing plate having a large area, it is very convenient for the visually impaired. In addition, it is easy to increase or decrease the force when a small amount is output, and the nozzle for discharging the liquid does not move up and down, so it is easy to receive the liquid. High safety due to round nozzles with rounded corners. Since no metal spring is used, it is easy to dispose of waste.

Hereinafter, embodiments of the present invention will be described.
(A) A pipe (9) for sucking and discharging the liquid content from the inside of the container (1) to the outside of the container is provided.
(B) The suction hole (10) of the pipe (9) is provided at the lower part inside the container, and the discharge-side tip at the upper part of the pipe (9) is connected to the discharge hole (11) provided outside the container. As shown in FIG. 5, the discharge hole (11) is provided with an outflow prevention valve (12) for preventing the outflow of the liquid contents when the container falls, and a round nozzle that can be detachably fixed. Attach (2). The outflow prevention valve (12) opens in the direction of discharging the contents from the inside of the container to the outside of the container when the elastic flexible (4) is pushed down to increase the air pressure in the container, and the air pressure in the container does not normally change. The discharge hole (11) is closed.
(C) An elastic flexible member (4) is provided on the upper portion of the container (1), and a hand push plate (5) is provided on the elastic flexible member (4). The elastic flexible member (4) has elasticity. When the elastic flexible member (4) is pushed downward through the push plate (5), the elastic flexible member (4) contracts downward, and when the hand is released from the push plate (5), the elastic flexible member extends upward. Return to the original position.
(D) An injection port (8) is provided on the upper part of the push plate (5).
(E) The inlet (8) is covered with a cap (7) with a valve mechanism provided with a valve mechanism.
(F) As shown in FIG. 3, the top plate (14) of the cap with valve mechanism (7) is provided with two left and right inner air holes (17) around the support shaft (15). Is provided with two check valves (16) for opening and closing the two left and right inner air holes (17).
(G) The cap with valve mechanism (7) is covered with the cap (6). At this time, an air passage, an outer air hole (18), and an inner air hole (17) are formed between the cap (6) and the cap with valve mechanism (7). Since the cap with valve mechanism (7) is covered with the cap (6), there is a waterproof effect against moisture falling from above. When the cap (6) is lowered to the lowermost position and is brought into close contact with the cap (7) with a valve mechanism, the outer air hole (18) and the inner air hole (17) can be closed to seal the container.
When the push plate (5) is pushed down, the elastic flexible (4) shrinks downward, and the air pressure in the container rises. At this time, the check valve (16), which is slightly larger than the inside air hole (17), is in close contact with the top plate (14) and closes the inside air hole (17). Therefore, the liquid content is pushed out to the liquid outlet (3) through the suction hole (10) in the container (1) by air pressure. Conversely, when the hand is released from the push plate (5), the elastic flexible (4) extends upward and returns to the original position. At this time, the pressure in the container (1) decreases, the check valve (16) bends in a direction to open the inner air hole (17), and the container (1) passes through the outer air hole (18) from the inner air hole (17). ) Send air inside. The check valve (16) normally closes the inside air hole (17) with no change in air pressure.
The present invention is configured as described above, and when it is used, the hand push plate (5) is lightly pressed down with a fingertip to receive the liquid coming out of the liquid outlet (3). When the finger is released from the push plate (5), the push plate (5) returns to its original position. Repeat this until the required amount is obtained.

    As shown in FIG. 7, the shape of the container, the shape of the elastic flexible member, and the shape of the push plate may be various.

    As shown in FIG. 8, the inner surface of the main body of the container (1) may have a structure such as an integral structure pipe (22) in which the inner surface of the container is a part of the structure of the inner surface of the pipe.

    The shape of the outflow prevention valve (12) and the check valve (16) may be various.
