Description

[Detailed description of the invention] Industrial field of application The present invention relates to a press injection device that deforms a container filled with a liquid by pressing it from the outside and injects the liquid by the deformation pressure. Various liquid contents such as hair cosmetics, liquid pharmaceuticals, etc. can be mixed with gas and sprayed in the form of a mist, and the liquid contents can be taken out in a normal liquid form.

BACKGROUND TECHNOLOGY Conventionally, there have been various types of press-injection devices that eject the liquid content by pressing and deforming a container filled with the liquid content from the outside and using the deformation pressure.

However, these pressure injection devices are only capable of spraying mist, and many of them cannot directly take out the liquid content without atomizing it.

In addition, in order to eliminate this drawback, there are devices that can perform liquid extraction and mist spraying, but it is not possible to easily switch between liquid extraction and mist spraying, and it is difficult to switch between liquid extraction and mist spraying. This required visual confirmation and careful movement.

Problems to be Solved by the Invention The present invention attempts to eliminate the above-mentioned drawbacks, and by deforming the container filled with the liquid by pressing from the outside, the liquid is injected by the deformation pressure. In the press injection device, it is possible to mix the liquid content with gas and spray it in a mist form, or to take out the liquid content in a normal liquid form.

In addition, this effect is made possible by a simple configuration, and the switching between mixing the liquid with gas and spraying it in a mist form, or taking it out in a normal liquid form can be done quickly without visually checking each time. This will enable you to do the following.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention has one end communicated with the liquid content in the container that is reversibly deformed by pressure, and the other end connected to the connecting body connected to the container. A liquid outlet hole is opened through the communication pipe to which the connecting body is fixed, and a gas outlet hole that can be connected to the cavity inside the container is installed on the outer surface of the connecting body at an appropriate distance from the liquid outlet hole. The gas outlet hole, the liquid outlet hole, and the liquid outflow hole are closed on the inner peripheral surface of the covering body which is rotatably fitted to the outer periphery of the connection body, and the covering body is provided on a part of the inner peripheral surface. As the connecting body rotates, a communication path is formed that connects the liquid outlet hole and the gas outlet hole, and a nozzle hole is formed in this communication path, and the connecting body, which is rotatably covered with a covering body, is removed from the mouth of the container. an engaging convex portion is provided protrudingly on one of the abutting end surfaces where the connecting body and the covering body abut, and this engaging convex portion is inserted into an engaging recess provided concavely on the other abutting end surface. In addition to being slidably inserted, a confirmation protrusion is formed in the engagement recess to project over which the engagement protrusion can ride over after engagement.

Function Since the present invention is constructed as described above,
After rotating the covering body around the outer periphery of the connecting body and connecting the communication passage of the covering body to the liquid outlet hole and the gas outlet hole, the container is pressed in an upright state. When the container is deformed by this pressure and the pressure inside the container is increased, the content liquid flows into the communication tube whose one end communicates with the liquid content and the other end is fixed to the connection body, and is guided to the liquid outlet hole. .

Since this liquid outlet hole penetrates to the outer surface of the connection body, the liquid content is injected to the outside from the nozzle via the communication path formed on the inner circumferential surface of the covering. In this injection, the communication passage is connected to the cavity inside the container when the container is upright, and is also connected to the gas outlet hole when the container is upside down, so the liquid content is mixed with gas and atomized. It is sprayed externally from the nozzle.

Next, the covering body rotatably fitted around the outer periphery of the connection body is rotated, and the gas outlet hole, the liquid outlet hole, and the liquid outflow hole are closed on the inner peripheral surface of the covering body. Due to this closure, the liquid content will not leak out even when the container is turned upside down, making it convenient for transportation, storage, preservation, etc.

In addition, if the cover is rotated and the liquid outflow hole of the connection body is connected to the communication path, the liquid outflow hole is always connected to the cavity in the container, so the liquid can flow out by turning the container upside down. The content liquid flows out from the nozzle in liquid form through the hole.

In addition, the above switching operation between liquid extraction and mist spraying can be confirmed by using your fingers to detect the confirmation protrusion protruding into the engagement recess as the engagement protrusion overcomes it as the covering rotates. and can be confirmed. This eliminates the need for careful operations such as visually checking the position of the covering each time the liquid and mist are switched, allowing for quick and error-free operation.

Further, a storage cylinder 11 is formed in this connection body 4 adjacent to the holding cylinder 5. This storage cylinder 11 has a gas outlet hole 12 and a liquid outflow hole 13 formed therein so as to penetrate to the outer surface of the connection body 4 .

This gas outlet hole 12 is connected to the hollow part 14 inside the container 2 when the container 2 is erected. When the container 2 is inverted, the gas outlet hole 12 and the empty space are connected to each other.
A check valve 17 consisting of a ball 15 and a valve seat 16 blocks the connection with the section 14 . Further, the liquid outflow hole 13 is formed so as to be constantly connected to the cavity 14 of the container 2. Although the check valve 17 is formed using the balls 15, it is of course possible to use the check valve 17 using other structures.

Further, a covering body 18 is rotatably fitted on the outer periphery of the connection body 4, and the inner circumferential surface 2 of this covering body 18 is rotatably fitted.
0, the gas outlet hole 12, the liquid outlet hole 10, and the liquid outlet hole 13 are brought into close contact with each other so as to be closable. In addition, the covering 1
A communication passage 21 is recessed in a part of the inner circumferential surface 20 of the housing 8 to connect the liquid outlet hole 10 and the gas outlet hole 12 as the covering body 18 rotates, and a nozzle hole 22 is provided in the communication passage 21. Form.

Further, an outflow path 23 is formed in a part of the inner circumferential surface 20 by providing an appropriate interval with this communication path 21 and connecting with the liquid outflow hole 13 as the covering body 18 rotates, and this outflow path At 23, an outlet 30 is formed to penetrate to the outer surface of the covering 18.

It is formed by being slidably inserted into an engagement recess 28 formed in the abutment end surface 25. Further, a confirmation protrusion 29 is protruded into the engagement recess 28 to enable the engagement protrusion 27 to get over the confirmation protrusion 29 after being caught by it as the cover 18 rotates. This crossing is sensed with the fingers, and the communication path 21, the gas outlet hole 12, and the liquid outlet hole 10 are
The connection between the outflow path 23 and the liquid outflow hole 13 can be confirmed without visual inspection.

Since the present invention is constructed as described above,
To take out the liquid content in a mist state, after connecting the communication passage 21 of the covering 18 to the liquid outlet hole 10 and the gas outlet hole 12, the container 2 is pressed from the outside in an upright position. When the container is deformed by this pressing and the pressure inside the container 2 is increased, the content liquid flows into the communication tube 1 which communicates with the liquid content at one end and is fixed to the connecting body 4 at the other end.

This liquid content is guided to the liquid outlet hole 10 of the communication pipe 1 via a ball valve 8 that opens only in the direction in which the liquid content is drawn out when the container 2 is erected. This liquid outlet hole 1
0 penetrates to the outer surface of the connection body 4, so
It is injected to the outside from the nozzle hole 22 through the communication path 21 of the connection body 4. During this injection, the communication path 21 is connected to the liquid outlet hole 10 and the gas outlet hole 12, as shown in FIG. Then, when the container 2 is erected, gas is introduced into the communication path 21 through the gas outlet hole 12 which connects with the hollow part 14 inside the container 2. By introducing this gas, the content liquid introduced from the liquid outlet hole 10 is mixed with the gas and agitated, and is sprayed outside from the nozzle hole 22 in a mist state.

After the spraying is completed, when the pressure on the container 2 is released, the ball valve 8, which opens only in the direction of discharging the contents, closes the lower valve seat 6 in the communication pipe 1. Due to this closure, the liquid content introduced into the communication pipe 1 remains retained without flowing back into the container 2. Therefore, the next injection will not result in a dry injection, and the content liquid can always be sprayed accurately.

Further, even if the container is inverted in this sprayable state, the liquid outlet hole 10 is connected to the communication pipe 1 when the container 2 is inverted.
When the container 2 is inverted, the ball valve 8 closes the valve seat 7, and the gas outlet hole 12 is also disconnected from the inside of the container 2 by the check valve 17 when the container 2 is inverted. It will not leak outside.

Next, the covering body 18 rotatably fitted around the outer periphery of the connecting body 4 is rotated and connected to any of the gas outlet hole 12, the liquid outlet hole 10, and the liquid outflow hole 10, as shown in FIG. Instead, the gas outlet hole 12, the liquid outlet hole 10, and the liquid outlet hole 13 are closed by the inner circumferential surface 20 of the covering body 18. This closure causes the container 2
There is no leakage of the liquid content even when the product is inverted.
It is convenient for transportation, storage, preservation, etc.

Further, in order to take out the liquid contents in a liquid state, the cover 18 is rotated to connect the liquid outflow hole 13 of the connection body 4 and the outflow path 23 as shown in FIG. With this connection, the liquid outflow hole 13 is connected to the cavity 14 inside the container 2.
Since the container 2 is inverted, the liquid inside flows out from the outlet 30 through the liquid outlet hole 13 and the outlet path 23 in a liquid state.

In addition, the above-mentioned confirmation of the switching operation between liquid extraction and mist spraying is performed when the engagement protrusion 27 overcomes the confirmation protrusion 29 protruding into the engagement recess 28 as the covering body 18 rotates. can be detected and confirmed with the fingers. This eliminates the need for careful operations such as visually checking the position of the covering 18 every time the liquid and mist are switched, allowing for quick and error-free operation.

In addition, when all the contents in the container 2 are injected by using such injection, the connecting body 4 is connected to the container 2.
By removing the container 2 from the container 2, the contents can be refilled and used.

Effects of the Invention As described above, the present invention deforms the container filled with the liquid by pressing from the outside, and mixes the liquid with the gas in the pressure injection device that injects the liquid by the deformation pressure. or spray it in a mist,
The liquid content can be taken out in normal liquid form. Therefore, it can be used in accordance with the purpose of use, and it is also possible to completely close the communication between the gas outlet hole, liquid outlet hole, and liquid outflow hole with the outside, making it convenient for transportation, storage, etc. Become something.

In addition, to confirm the switching operation between taking out the liquid content and spraying the mist, use your fingers to watch the engagement protrusion go over the confirmation protrusion that protrudes into the engagement recess as the cover rotates. can be detected and confirmed. This eliminates the need for careful operations such as visually checking the position of the covering every time the liquid and mist are switched, allowing for quick and error-free operation.
