してきた。2. Description of the Related Art It has been conventionally practiced to foam a content liquid in a container into a foam by a manual foam ejection pump. For example, in Japanese Utility Model Laid-Open No. 63-74482, the check valve 1 is located below the piston 3 inserted in the cylinder 2 and above the bottom of the liquid passage hole 10.
Vent hole 13 located below container 1 and inside container 1
A dispensing container for a foamable liquid is described. But,
The position of the vent hole 13 is below the check valve 11, and the container 1
Since it is located inside, the vent hole 13 has an exhaust function but does not have an intake function, so the function of the vent hole 13 becomes extremely slow, and When the foaming liquid is dispensed, the inside of the container 1 tends to be in a vacuum state, and in the worst case, there is a drawback that it becomes unusable. Also, the actual exploitation 63-13280
The publication describes a dispensing container for a foamable liquid that accommodates an expandable and contractible foam-generating member in a piston chamber housing, but since it does not show an intake hole, it just sucks up the liquid. In addition, since the ejection port is not shown, the related configuration of the main body part of the dispensing container for the foamable liquid and the ejection port part is unknown. This is a conventional technique, which cannot be said to be the feature of the device described in Japanese Utility Model Laid-Open No. 63-13280. Further, Japanese Utility Model Laid-Open No. 62-177653 discloses a dispensing container for a foaming liquid which can close the intake on-off valve when the piston is pressed and can open the intake on-off valve when the piston is pulled up. Has been done. However, since the nozzle 13 and the piston 3 are screwed together and integrated, workability during manufacture is poor, and the resulting product has unevenness in quality and the function of the product is unstable. Further, there is no appropriate mechanism that allows outside air to enter, and the operating portions of the vent hole 9 and the check valve 11 provided in the cylinder 2 are hard to function sufficiently. Therefore, if the dispensing container for the foamable liquid is used, the air in the container is discharged to the outside, and the pressure in the container decreases, and the container becomes unusable at an early stage. In other words, there is a drawback that the distribution of intake air is not good because no consideration is given to intake air from the outside. Therefore, in a conventional dispensing container of a foamable liquid, when discharging in the form of foam, the foam state of the discharged substance is made into fine bubbles, and the foam state is discharged to the outside for a relatively long time, It was extremely difficult to make the foam of the discharged product into a fine pump to maintain the fine foam and to endure the use. Therefore, the parties have been struggling to obtain the appropriate technical means for solving the technical problem to bring the finely foamed state.

設けた噴射口２２から泡状態にして噴射させ得る。The present invention comprises a lid 1 for a contents container, a push button type injection head 2, and a piston mechanism interposed between the lid 1 and the injection head 2, and a piston chamber of the piston mechanism is formed. A fluid that is provided separately on the lid 1 and is expandable and contractable in the space of the piston chamber formed by the sliding relationship between the piston mechanism cylinder portion 3 and the piston mechanism cylinder portion 3 piston portion 4. An injection provided in the push-button injection head 2 for accommodating a bubble-forming member made of a permeable material and generating bubbles by contact between the content flowing in from the content container and the air flowing in from the outside through the piston mechanism. So that it can be sprayed from the mouth 22 to the outside,
The push button type injection head 2 and the piston head supporting tubular portion 9 are simply joined together by pushing the lower opening portion of the push button type injection head 2 into the tip portion of the piston head supporting tubular portion 9. So that the piston mechanism can be moved up and down by interposing a spring 23 between the lower part of the push button type injection head 2 and the upper part of the contents container lid 1. When not in use, the upper check ball valve 5 can be stopped by the injection cylindrical body 26 to prevent erroneous injection, and the intake port 8 having a relatively large number of openings is provided. The intake on-off valve 12 is positioned at a certain position, and the intake on-off valve 12 is arranged on the outer side of the foam-forming member made of a stretchable fluid permeable material, so that it is externally exposed in the state of fine bubbles. Is it a foam pump that can be injected? When the push button type injection head 2 of the bubble pump of the present invention is pressed against the spring 23, the piston portion 4 descends with the cylinder portion 3 of the piston mechanism as a guide, and the cylinder portion 3 and the piston portion 4 The volume of the piston chamber formed by the piston chamber is reduced, and the content in the piston chamber is raised through the through hole of the piston head supporting tubular portion 9 provided at the center of the piston portion 4. A relatively large number of intake holes 8 provided in a portion outside the protrusion 10 in the central portion of the container lid for guiding the head-supporting tubular portion, and a piston head facing the portions of the relatively large intake holes 8. A relatively large number of intake holes corresponding to the intake holes 8 are provided in the portion 11 and the piston head 11
The air sucked from the intake on-off valve 12 provided at an appropriate portion of the piston portion 4 facing the above portion comes into contact with the contents to form bubbles, which can be ejected from the injection port. In the foam pump, the piston mechanism cylinder portion 3 is provided with a member made of a material that is expandable and contractable and has a large number of communication holes, and the peripheral portions of the intake on-off valve 12 and the piston head 11 provided on the member. It is possible to obtain a foam having a desired size by bringing it into contact with the air sucked into the piston chamber through the intake hole 8 provided in the section. Further, by appropriately selecting the stroke amount of the piston portion 4 and the diameter of the cylinder portion, the ejection amount of the foamy material can be adjusted. When the push button type injection head 2 is pressed, the ball check valve 6 located at the lower end opening of the piston mechanism cylinder portion 3 is closed, and the ball check valve in the valve chamber provided in the injection head 2 is closed. Valve 5
Is pushed up by the foam, and the foam is ejected from the ejection port 22. Therefore, the ball-shaped check valve 6 in the valve chamber provided in the injection head 2 is normally placed in the upper end opening of the piston head supporting tubular portion 9 and the opening is closed. I'm running. Then, the push button type injection head 2 is connected to the spring 23.
When pressed against, the cylinder portion 3 of the piston mechanism guides and the piston portion 4 descends, the volume of the piston chamber formed by the cylinder portion 3 and the piston portion 4 is reduced, and the contents in the piston chamber are reduced. The object is lifted up through a through hole provided in the center of the piston portion 4, while the air sucked from a relatively large number of intake holes near the peripheral portion of the piston head 11 comes into contact with the content. And becomes a foam and is ejected from the injection port 22, while the ball check valve 6 located at the lower end opening of the piston mechanism cylinder portion 3 is closed and the piston mechanism cylinder portion 3 is closed.
The fluid contained in is blocked by the ball check valve 6 and does not flow back into the container. Then, when the pressing of the push button type injection head 2 is stopped, when the push button type injection head 2 is pushed up by the elastic force of the spring 23 provided inside the injection head 2, it is positioned at the lower end opening of the piston chamber 19. The ball check valve 6 is floated by the negative pressure in the piston chamber 19 so that the content liquid in the container flows into the piston chamber. By repeating this, the content liquid in the container flows into the piston chamber 19 and bubbles are generated by contact with the air flowing from the outside, and the bubbles are generated in the injection port 22 provided in the injection head 2. It can be made into a foam state and injected.

Particularly, in the foam pump of the present invention, the piston mechanism cylinder portion 3 is provided with a member made of a material that is expandable and contractable and has a large number of communication holes, and the intake opening / closing valve 12 and the piston head are provided on the member. Intake hole 8 provided in the peripheral portion of the portion 11
Therefore, there is an effect that a foam having a desired size can be obtained by contacting with air sucked into the piston chamber. Further, by appropriately selecting the stroke amount of the piston portion 4 and the diameter of the cylinder portion, the ejection amount of the foamy material can be adjusted. In use, when the push button type injection head 2 is pressed, the ball check valve 6 located at the lower end opening of the piston mechanism cylinder portion 3 is closed, and the injection head 2 is closed.
There is an effect that the foam can push up the ball-like check valve 5 in the valve chamber provided in the above to eject the foam from the injection port 22. Therefore, the ball-shaped check valve 6 in the valve chamber provided in the injection head 2 is normally placed on the upper end opening of the piston head supporting tubular portion 9 and the opening is closed. In addition, when the push button type injection head 2 is pressed against the spring 23 in use, the piston portion 4 descends with the cylinder portion 3 of the piston mechanism as a guide, and the cylinder portion 3 and the piston The volume of the piston chamber 19 formed by the part 4 is reduced, and the contents in the piston chamber 19 are raised through a through hole provided in the center of the piston part 4, with the piston head 11
The air sucked from a relatively large number of intake holes near the peripheral edge of the air comes into contact with the contents to form bubbles, which are ejected from the injection port 22, and, on the other hand, the lower end opening of the piston mechanism cylinder portion 3 The ball-shaped check valve 6 located at is closed,
The fluid contained in the piston mechanism cylinder portion 3 is blocked by the ball check valve 6 and does not flow back into the container. Then, when the pressing of the push button type injection head 2 is stopped, when the push button type injection head 2 is pushed up by the elastic force of the spring 23 provided inside the injection head 2, the piston chamber 1
The ball-shaped check valve 6 located at the lower end opening of 9 has the effect of being floated by the negative pressure in the piston chamber 19 so that the content liquid in the container flows into the piston chamber. In addition, by repeating such a thing, the content liquid in the container flows into the piston chamber, and bubbles are generated by contact with the air flowing from the outside, and the bubbles are ejected from the ejection port 22 provided in the ejection head 2. When spouting foam from the foam, the foam state of the spout is made into a fine bubble and spouted to the outside in the state of that foam, and the bubble state of the spout is fine for a relatively long time. There is an effect that can be maintained and used.
