Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a dispensing container, and particularly to a dispensing container that mixes air into a fluid to form a foam and then dispenses the fluid.

[Conventional technology]

Conventionally, various containers have been provided that mix air into a fluid and pour it out in a so-called foam form, but conventionally, a pressure container filled with low-pressure gas such as fluorocarbon gas has been common. .

This type of dispensing container forms the fluid by mixing the fluid into the path through which the contained low-pressure gas expands.

[Problem that the invention attempts to solve]

However, in the conventional method described above, a pressure container and a low pressure gas to fill it are essential, so of course the cost is high, and the container must be filled with fluid and low pressure gas in an appropriate ratio. Must. For this reason, the storage capacity of the fluid relative to the volume of the container decreases, and in order to secure sufficient internal capacity, the container becomes larger.
There are drawbacks that make it inconvenient for mobile phones.

Furthermore, this type of container cannot be reused, making it uneconomical, and it is inconvenient that a hole must be made to prevent explosions when it is disposed of.

The present invention has been developed in view of the above points, and can be used in a special position, and can dispense fluid in a foamed state without using a special pressurizing gas. It is an object of the present invention to provide a dispensing container that can be easily refilled and whose internal capacity can be used effectively to accommodate a fluid.

[Means for solving problems]

In order to solve the above technical problem, the present invention takes the following technical measures.

That is, a cylindrical body 6 having a spout is provided to the spout cap 3 to be attached to the spout 2 provided on the container body 1, and a cylindrical body 7 is attached to the cylindrical body 6.
mate.

A spiral groove 8 whose lower end communicates with the inside of the container and whose upper end communicates with the spout is provided on the outside of the tube body 7, and a fluid outflow hole 10 is bored from the inside thereof to the spiral groove 8. .

Further, a check valve for blocking air intake is provided below this tube, while a container main body 1 is provided at the lower end of the tube 7.
A fluid tube 13 extending to the bottom of the container was joined to form a pouring container.

The check valve may be a ball valve, and operates to prevent air from entering the fluid when air is drawn into the container body.

[Effect]

When the container body 1 is pressurized with the spouting cap 3 side facing upward, the fluid rises up the fluid tube 13 and flows out from the fluid outlet 10 side into the spiral groove 8. At the same time, the pressurized air within the container rapidly rises within the spiral groove 8.

For this reason, air that rapidly rises in the spiral groove 8 is mixed into the fluid, moves toward the spout 4 side while forming a foam shape, and flows out of the container. here,
When the pressure on the container body 1 is released, the check valve enters a blocking state, and outside air is sucked into the container through the spiral groove 8. Therefore, air is not ejected into the fluid 9 through the fluid pipe 13, and no bubbles are generated within the container.

Then, the container body 1 becomes compressible again.

〔Example〕

Embodiments of the present invention will be described based on the drawings.

(First Embodiment) The container body 1 is a so-called squeeze bottle that deforms when pressed, and has a spout portion 2 on its top surface.
has been erected. A spout cap 3 is screwed onto the spout portion 2, and a cylindrical body 6 having a spout 4 is formed on the upper surface of the spout cap 3. Note that a nozzle 5 is attached to the spout 4.

A tube body 7 is fitted inside the cylindrical body 6. The tube body 7 has a closed upper part, and a ring part 7b having a window 7a on the side surface is provided above the tube body 7. Further, a rectifying projection 7c formed in a conical shape is provided on the upper surface of the blocking plate.

A spiral groove 8 is provided around the outside of the tube body 7, and the spiral groove 8 has a lower end 8a communicating with the inside of the container and an upper end 8b communicating with the spout 4 through a window 7a. The air pumped from the lower end 8a can be discharged through the spiral groove 8.

The pipe body 7 is provided with one or more, for example, several, fluid outflow holes 10 extending from the inside thereof to the spiral groove 8.

A cylindrical casing 12 containing a sphere 11 is provided at the bottom of the tube body 7, and this casing 12
A valve seat 12a is provided on the lower side of the valve seat 12a, and a ball holding protrusion 12b is protruded in the middle of the valve seat 12a, so that it operates as a check valve to prevent air from being taken in from the spout 4. It's getting old. Further, a fluid pipe 13 extending to the bottom of the container body 1 is joined to the lower end of the casing 12.

When the container body 1 is pressurized, the sphere 11 is pressed against the sphere holding protrusion 12b, and the fluid 9 is pressed against the sphere 11.
and the ball holding projection 12b.

On the other hand, in the non-pressurized state or when the container body 1 is depressurized, the sphere 11 is pressed against the valve seat 12a, and the casing 12 is in the blocking state.

An example of the operation of the above configuration will be explained based on FIG. 3.

First, hold the container body 1 and compress the container body 1 with the pouring cap 3 facing upward. Then, the fluid 9 (arrow L) is connected to the fluid pipe 13 and the casing 1.
2 and flows into the pipe body 7 side, and the fluid flows into the pipe body 7 side through the fluid outflow hole 1.
0 into the spiral groove 8.

At the same time, compressed air (arrow F) in the container body 1 flows in from the lowest part of the spiral groove 8 and is ejected from the spout 4 through the window 7a.

Therefore, the fluid 9 rises within the spiral groove 8 and is ejected from the spout 4 while being mixed with the compressed air.

Here, when the pressure on the container body 1 is released, the sphere 1
1 falls, the casing 12 becomes closed, and outside air is taken into the container body 1 through the spiral groove 8.

In this way, since air is taken in through the spiral groove 8, air is not mixed into the fluid 9 through the fluid pipe 13, and no bubbling occurs.

(Second Embodiment) FIG. 4 shows a second embodiment, in which the cylindrical body 6 is extended below the pouring cap 3.

(Third Embodiment) FIG. 5 shows a third embodiment, in which a threaded portion for screwing into the mouth tube portion 2 is formed at the lower part of the nozzle 5.

Further, a screen S is provided in the flow path from the pipe body 7 to the spout 4, so that the ejected foam is further finely pulverized. Furthermore, a lid 5a is detachably provided at the tip of the nozzle 5.

(Fourth Embodiment) FIG. 6 shows a fourth embodiment, in which, in addition to what is shown in the third embodiment, a screen holder 3b for holding down the screen S is provided, and this screen holder 3b is It is inserted between the pouring cap 3 and the nozzle 5. Similar to the third embodiment, a lid 5a is removably provided at the tip of the nozzle 5.

(Fifth Embodiment) FIG. 7 shows a fifth embodiment, in which the spout 4 is formed thickly, and an inner lid 5b is fitted to the tip thereof,
A lid 5b is attached to overlap this inner lid 5b.

Incidentally, as described above, in each of the embodiments, the container is used in an upright state, but it is also possible to use it in an inverted state.

Moreover, in each of the above embodiments, the sphere 1 is used as a check valve.
1 was used as the valve, but the invention is not limited to this example, and a plate material may also be used as the valve.

[Effect of idea]

According to the present invention, since the fluid ejected from one or more fluid outflow holes is mixed into the air flowing out through the spiral groove to contain air bubbles, the container is squeezed in an upright position. By doing so, fine bubbles can be included in the fluid.

Furthermore, since the fluid moves along the spiral groove after being mixed, the kneading section with air can be set long, and a large amount of air bubbles can be uniformly included. Therefore, a high quality foam can be generated.

In addition, since the device is configured to operate by compressing the container body, no pressurizing gas is required, and the volume of the container can be effectively used as a space for accommodating the fluid. Furthermore, the contents can be easily refilled by removing the dispensing cap screwed onto the spout.

The air sucked into the container is quickly sucked into the container via the spiral groove, and does not pass through the fluid pipe and generate bubbles within the container.
