Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a foam-jetting container in which the liquid inside the container is foamed and ejected by elastic compression of the container body.

``Prior art'' A cap with a nozzle is screwed onto the mouth and neck of a container body having a barrel that can be compressed elastically, and a liquid outlet tube communicating with the nozzle is vertically disposed below the container body. A foam ejection container is known in which an air permeable member for foaming is fitted in the upper part and an air intake port is provided in the upper part of the outflow tube below the member.

``Problems to be solved by the invention'' In the conventional foam-jetting container described above, when the body is squeezed, the liquid inside the container flows through the liquid outflow tube hole, and the air above the surface of the liquid inside the container passes through the air intake port. The liquid and air are mixed and foamed during the passage through the breathable member, and the foam is ejected from the nozzle. When the body is released from compression, the body elastically restores the nozzle and air. Outside air was sucked into the container body through the breathable member. Therefore, when not in use, the air permeable member dries out, and the liquid component crystallizes, causing the air permeable member to become clogged, resulting in incomplete foaming.

The present invention is designed to prevent the above-mentioned air-permeable member from drying out, thereby eliminating the above-mentioned drawbacks.

"Means for Solving the Problems" A container body 1 has a body 2 which can be elastically compressed, and a neck part 4 stands up from the upper end of the body, and a bottom on the upper end surface of the mouth neck of the container body. A first peripheral wall 8 rising from the periphery of the wall 7
The container-shaped portion is suspended within the container body by engaging the outward flange 9 at the upper end, and an outflow pipe 11 is projected in the vertical direction from the opening 10 at the center of the bottom wall 7, and an outside air intake valve 12 is installed at the upper end of the upper outflow pipe portion. established,
A receiving member 6 in which a first through hole 13 and a second through hole 14 are bored in an upper portion of the outflow pipe below the valve and an upper end portion of the first peripheral wall, and the upper outflow pipe portion 11a.
The top wall 26 is sandwiched between the upper end of the mouth and neck portion and the breathable member 23 which has a cylindrical portion fitted onto the outer surface and the first through hole 13 is closed by the upper cylindrical portion. The second peripheral wall 27 hanging down from the peripheral edge of the top wall is fitted into the container mouth neck 4, and the upper outer surface of the breathable member 23 is brought into surface contact with the lower inner surface of the nozzle 28 rising from the top wall. A cap-like member 25 is fitted into the nozzle hole of the nozzle, and a cap part 30 hanging from the lower surface of the cover plate 29 rotatably attached to the upper end of the second peripheral wall is removably fitted into the nozzle hole of the nozzle. , the inner surface of the mouth and neck and the first peripheral wall 8
There is a flow path forming space 22 between the two, and a liquid reservoir space 24 between the inner surface of the container-shaped part and the lower outer surface of the breathable member.
were formed respectively.

"Operation" When the lid plate 29 is removed from the state shown in FIG.
The liquid inside the container passes through the nozzle hole 28a and flows through the second outflow pipe 20 to the second container-shaped part 21.
Inside, the outflow pipe 11, the first through hole 13,
They pass through the air permeable member 23 and are ejected from the nozzle holes 28a, but as they pass through the air permeable member, the air and liquid mix and foam, and are ejected as bubbles from the nozzle holes. When the body 2 is released, outside air enters the container body through the nozzle hole 28a, the outside air suction valve 12, the first through hole 13, the ventilation member 23, and the second through hole 14, and the body restores its original state. The container can also be used in an inverted position, in which case liquid is forced out of the air passageway and air is forced out of the liquid passageway, mixing in the air-permeable member and ejecting it as foam. In this case, the liquid that was in the second outflow pipe 20 when standing upright is stored in the second container-shaped part 21 so that the liquid does not enter into the outflow pipe 11.
The second outflow pipe hole 20a and the outflow pipe hole 11c are located on different vertical lines. When the container body is returned to an erect state after use, liquid will be accumulated in the air 24 between the inner surface of the container-shaped part and the lower outer surface of the breathable member, and the plug part 30 will close to the nozzle hole 28a due to the cover plate 29 being closed. Since the air permeable member 23 is closed, the air permeable member 23 does not come into contact with the outside air.

"Example" The container body 1 has a body part 2 which can be elastically compressed, and a mouth and neck part 4 is erected from the upper end of the body via a shoulder part 3.

A receiving member 6 is suspended into the container body.
This member suspends the container by engaging the outward flange 9 at the upper end of the first peripheral wall 8 that stands up from the periphery of the bottom wall 7 with the upper end surface of the mouth and neck of the container body, and also suspends the container-shaped portion through the opening in the center of the bottom wall 7. Outflow pipe portions 11a and 11b are made to project upward and downward from the portion 10, and an outside air suction valve 12 is provided at the upper end of the upper outflow pipe portion. Further, a first through hole 13 and a second through hole 14 are formed at the upper end of the upper outflow pipe section below the valve and at the upper end of the first peripheral wall, respectively. The outside air intake valve 12 may be formed to be able to take in outside air, and for example, as shown in the figure, a plurality of protrusions 15 are provided on the inner surface of the upper end of the outflow pipe hole.
At the same time, a downwardly facing stepped portion 16 is provided around the inner surface of the outflow pipe hole below the protrusion, and the outer peripheral portion of the cap 17 is engaged with the top surface of the tip of the protrusion, and a rod portion 18 is suspended from the center of the cap. Elastic plate 1 attached to the bottom end
9 may be brought into pressure contact with the downward step portion 16. The downward outflow pipe portion 11b may be vertically provided below the container body, or it may be provided short as shown in the figure, and the second container-shaped portion 21 having the second outflow pipe 20 is connected to the lower end of the container body. The lower outflow pipe portion 11b may be fitted in an air-tight or water-tight manner and may be suspended into the second container-shaped portion 21. In this case, there is a second pipe on the downward extension line of the outflow pipe hole 11c.
The outflow pipe holes 20a are provided so that they do not overlap. The outer diameter of the first peripheral wall is smaller than the inner diameter of the mouth and neck,
A flow path forming gap 22 is formed between them.

Reference numeral 23 denotes a cylindrical breathable member made of a sintered body, a sponge, or the like, and the cylindrical portion is fitted onto the outer surface of the upper outflow pipe portion 11a to close the first through hole 13 with the upper cylindrical portion. The outer diameter of the cylindrical portion is the first peripheral wall 8
The diameter is smaller than the inner diameter, and a liquid reservoir space 2 is provided between the inner surface of the container-shaped part and the lower outer surface of the breathable member 23.
Set 4. At least the upper part of the cylindrical part is preferably formed into a tapered shape.

The cap-like member 25 has a second circumferential wall 27 extending vertically from the outer periphery of the top wall 26 and screwed onto the container mouth neck 4, and an outward flange 9 between the lower surface of the top wall 26 and the upper end surface of the mouth neck. is held in between. A tapered nozzle 28 stands up from the center of the top wall, and the upper outer surface of the breathable member 23 is fitted into the lower inner surface of the nozzle in surface contact. Further, a cover plate 29 is rotatably attached to the upper end of the second peripheral wall, and a plug portion 3 extending vertically from the lower surface of the cover plate is fitted into the nozzle hole 28a to close it.

"Effect of the invention" The present invention has the above-described configuration, and since the liquid reservoir space 24 is provided between the outer surface of the breathable member 23 fitted on the outer surface of the upper outflow pipe portion 11a and the inner surface of the container-shaped part, The liquid accumulated in the space wets the air permeable member and prevents it from drying out, and the plug portion 30 of the nozzle hole is closed to prevent the air permeable member from coming into contact with the outside air. It is possible to prevent the air permeable member from clogging due to crystallization due to drying.
