As in the present embodiment, the partition in the present invention may be broken by the liquid pressure of the content liquid when pressed and deformed, but instead, it is broken by breaking the partition such as the partition wall by pressing. May occur and the partition function may be lost. For example, the partition can be selected to be easily damaged by pressing by being made of a brittle material. As the “brittle material”, a general brittle material such as a metal or a brittle resin can be used. When plastic is used for a brittle material, for example, by adjusting the additive (adding or removing the additive) and setting the Tg (glass transition point) above the operating temperature, the plastic becomes brittle. Is possible. A preferable Tg temperature is 40 ° C. or higher, more preferably 60 ° C. or higher.
The function of the present invention can also be achieved by making the partition easy to break by inserting a break line (break guide means) or the like in advance. As the breakage induction means, it is effective to put a break line in the partition in advance, or to reduce a part of the thickness so as to be easily broken. In addition, for example, a slit that reaches the middle of the wall thickness can be inserted in the partition wall made of plastic, or a concave portion having a depth up to the middle of the wall thickness can be formed in an arbitrary pattern.

In the foaming tool 1A of the present embodiment, the foaming member 3 made of a soft porous material and the liquid 6 having foaming properties are accommodated in the tube container 2A described above.
Soft porous materials include foamed polyurethane, foams of soft resins such as crosslinked and non-crosslinked polyethylene, porous bodies (skeletons) obtained from sponges, nets made of synthetic resins, etc. From the viewpoint of efficiently generating fine bubbles, it is preferable to use a soft resin foam or a sponge made of a sponge skeleton.
The fineness of the soft resin foam (soft porous material) can be expressed by the number of cells, which is the number of holes in 25 mm. Some finer eyes can make a tight bubble, but if it is too fine, it is difficult to take in air and it is difficult to foam, so the number of cells is preferably 20 to 70/25 mm, more preferably 30 to 70 / 25 mm, more preferably 30 to 35/25 mm.
The number of cells is determined by the method described in JIS K6400-1: 2004.

The hole opened at only one end preferably has a depth of 1/3 or more of the distance between the surface where the hole opens and the opposing surface facing the surface, and has a depth of 1/2 or more. It is preferable.

Moreover, although only one foaming member 3 may be accommodated in one container 2 such as a tube container 2A, a plurality of foaming members 3 are accommodated in one container 2 as shown in FIG. It is preferable from the point which produces a fine bubble more effectively.
The number of foaming members 3 accommodated in one container is preferably 3 or more, more preferably 5 or more, still more preferably 10 or more, preferably 300 or less, more preferably 200 or less.
Examples of the foaming member 3 in the case where only one foaming member 3 is accommodated in the container include those having a size and an outer shape along the inner shape of the container.

  Moreover, as a shape of the foaming member 3, it is preferable that it is a rectangular parallelepiped (a cube is included), for example, as shown in FIG. It can be made into the shape. For example, a cylindrical shape, a conical shape, a truncated cone shape, a prismatic shape, a pyramid shape, a truncated pyramid shape, a spherical shape, a hemispherical shape, and the like can be used. Moreover, the foaming member 3 from which a shape differs can also be used in combination.

The size of the foaming member 3 is preferably a size that does not leak outside through the discharge part 21. Moreover, if the size of each foaming member 3 is too small, the foam generating power is reduced. Therefore, the volume of individual foaming member 3, preferably 0.785 cm ³ or more, more preferably 1 cm ³ or more. There is no particular upper limit, but it is preferably, for example, 125 cm ³ or less. The volume of each foaming member 3 includes the volume inside the pores of the porous material constituting the foaming member 3 and the volume inside the hollow portion 32 formed of the above-described through hole or stop hole.

The liquid 6 having foaming property is capable of producing a large number of bubbles by being compressed together with the foaming member 3 in a state of being in contact with the foaming member 3. The liquid having foaming properties preferably has at least one kind of surfactant.
The surfactant may be any of an anionic surfactant, a cationic surfactant, and a nonionic surfactant. Further, the surfactant can be used without particular limitation depending on the use of the liquid having foamability. Moreover, also about components other than surfactant, the various components conventionally used for the use can be mix | blended without a restriction | limiting especially according to the use of the liquid which has foamability. From the viewpoint of improving foaming properties, the content of the surfactant in the foaming liquid is preferably 10% by mass or more, more preferably 15% by mass or more, and preferably 40% by mass or less. More preferably, it is 30 mass% or less, Preferably it is 10-40 mass%, More preferably, it is 15-30 mass%.

Examples of the use of the liquid having foaming properties include face wash, hand soap, dish detergent, shampoo, and eyeglass wiping agent.
When the use of the liquid is a cleaning agent, it is more preferable that at least the cleaning substrate shown in Table 1 below is included in the liquid at a ratio (mass%) shown in Table 1, for example.

According to the foaming tool 1A of the present embodiment, by pressing the body portion 23 which is the pressing deformation portion 22 with both hands or one hand, the separation state by the partition wall (partition) 8 is released, and foaming properties are obtained. The liquid 6 comes into contact with the foaming member 3.
And in the state which the liquid 6 which has foamability, and the foaming member 3 contacted, the foaming member 3 of the state which the liquid 6 impregnated was compressed by pressing the trunk | drum 23 which is the press deformation part 22 again. Can be made. The pressing of the body portion 23 is preferably repeated twice or more, and more preferably three or more times, more preferably because the foam quality becomes uniform, with the first pressing of releasing the separation state by the partition wall 8 or the like. .
Then, by compressing the foaming member 3 impregnated with the liquid 6, many fine bubbles are generated inside the container 2. By repeating the compression a plurality of times, a large number of fine bubbles can be generated more reliably. In addition, the foaming tool 1A of this embodiment can perform the above-described series of operations while holding the container main body 20 with one hand and holding the container main body 20 with one hand, and is extremely excellent in workability.
Then, by pressing the pressing deformation portion 22 of the container 2 again in the state where the discharge portion 21 is released, the fine bubbles 4 generated inside the container are discharged as shown in FIG. It can be discharged from the portion 21 onto the palm 5 or the like.

According to the foaming tool 1A of the present embodiment, fine bubbles can be easily generated in this manner. Moreover, when the bubbles are generated, the liquid inside and the generated bubbles are not attached to the hand. For this reason, for example, even when a facial cleanser is used with a foam facial cleanser, the facial cleanser can be washed by placing it in the minimum necessary area of the palm. Can be washed away with hot water.
In addition, for the foaming tool 1 </ b> A that is a tool, the processing after use is only required to close the discharge part 21 with the opening / closing cap 29. Therefore, it is not necessary to wash away the facial cleanser and the like adhering to the tool, and the burden of cleaning up the tool after washing the face is reduced.
Moreover, the foaming member 3 can be made to exist in the vicinity of the discharge part 21, and the foam | bubble size can also be equalized by passing the inside of the foaming member 3 and pushing the foam | bubble produced inside inside.

In addition, the liquid 6 having foaming properties is initially separated from the foaming member 3, and the partition is broken by a predetermined operation such as pressing and deforming the pressing deformation portion so that the two come into contact with each other. Even when the liquid 6 having foaming properties has a property that the freshness is lowered when it contacts the foaming member 3, the freshness can be maintained for a long time.
In addition, when a liquid having foaming property is brought into contact with the foaming member 3 for a long time, the liquid may have a problem such as a smell of the foaming member 3 being transferred to the liquid. By making both contact with each other, such inconvenience can be eliminated or reduced.

  In the present invention, it is preferable that the container has a capacity that can be used once. Thereby, it becomes possible to improve the functionality at the time of face washing. By putting an appropriate amount of the facial cleanser in the container, an appropriate foaming and facial cleansing effect can be obtained. Moreover, foaming can be obtained regardless of the place of use. In particular, when the hand is blocked, it is possible to perform foaming and face washing with a single hand operation. Here, the capacity of using the container once, for example, in the case of makeup removal, means the amount of makeup removal used at one time until the end of face washing, and the content described in the book as usage.

Moreover, according to the foaming tool 1A of this embodiment, the liquid 6 which has foaming property is accommodated in the tube container 2A in the state separated from the foaming member 3 by the partition.
Therefore, even if the liquid stored in the container 2 is a liquid product or the like that has conventionally been low in viscosity and is not suitable for a tube container, it can be sold in a tube container. For example, the liquid contained in the tube container may have a specific gravity of 1.1 or less, and further 1.0 or less. However, the specific gravity is preferably 0.9 or more. The tube container is conventionally used as a paste-like container.

In order to generate bubbles inside the container 2, air needs to be present inside the container 2. Therefore, in order to be able to perform a foaming operation in a state where the discharge unit 21 is closed, for example, when the foaming tool 1A of the present embodiment is marketed as a facial cleanser containing a tube container, the consumer can set the discharge unit. It is preferable that air is contained inside from the state before release.
Further, the foaming operation may be performed in a state in which the discharge unit 21 is released. For example, if the released discharge unit 21 is pressed upward, liquid or bubbles in the container leak unintentionally. It is possible to generate bubbles in the container while preventing this. Assuming that it is used in this way, air may be taken into the interior for the first time by the consumer releasing the discharge part.

  In the foaming device of the present invention, gas such as air is contained in the container 2 in an unused state where the foam discharge portion is not opened (for example, a state where the foam is displayed as a product on a shelf or the like in a store). It is preferable.

  Further, in the foaming tool 1C of the present invention, a plurality of types of foaming members 3A and 3B having different fineness of the soft porous material may be accommodated in the container 2 as the foaming member 3. preferable. For example, as two types of foaming members, a fine foaming member and a foaming member having a coarser mesh than the foaming member are accommodated, so that dense foam is produced by the fine foaming member. On the other hand, it is possible to improve the foam dischargeability and the resilience when the container 2 is pressed and compressed by the foaming member having a relatively coarse eye.

In the present invention, a foaming member, a foaming liquid, and air are usually present in the container, but it is not necessary that all foaming members are filled with the foaming liquid. Foaming property can be improved by having the place which is not filled with the liquid so that air can pass the inside of the foaming member.
That is, it is preferable that the foaming member of the present invention has a foaming member that is not completely immersed in the liquid when the foaming member 3 and the liquid having foaming properties are in contact with each other. For example, in the first embodiment, when the separation state by the partition wall 8 is released, a foaming member immersed in a liquid having foaming properties and a foaming member that is not completely immersed in the liquid are generated. It is preferable. The foaming member immersed in the liquid is one that is entirely immersed in the liquid, and the foaming member that is not completely immersed is one in which the whole or a part is exposed from the liquid. A foaming member that is not fully immersed contains gas and does not contain the maximum amount of liquid that can be contained in the foaming member.
By including the foaming member immersed in the liquid and the foaming member that is not completely immersed, the liquid and the gas can be mixed more satisfactorily and fine dense bubbles can be generated.

The present invention is not limited to the above-described embodiment.
For example, in the foaming tool of the first embodiment, the partition wall 8 is provided as a partition for holding the foaming member 3 and the liquid having foaming properties in a separated state, but instead, the foaming property is provided. It is also preferable to store the foaming member 3 and the foamable liquid in a separate state in the container 2 by storing the liquid in a bag that is easily broken.
Moreover, the formation mode of the partition wall 8 is not limited to that shown in FIG. 1, and can be formed in various modes as long as the liquid 6 having the foaming property and the bubble member 3 can be separated and held. . For example, a partition wall may be formed in the central portion of the tube container 2A in the axial direction (vertical direction in FIG. 1) extending in a direction orthogonal to the axial direction.

  Further, in the tube container 2A according to the present invention, the tubular tube body constituting the trunk portion 23 and the mouth portion forming member 25a may be formed by integral molding. In addition, the tube container may be provided with an opening / closing cap capable of opening / closing the mouth part 25 directly to the mouth part 25 of the container body 20 by screwing, fitting, engagement or the like. The cap base 27 and the opening / closing cap 29 in the cap member 26 may not be connected via the hinge portion 28 and may be completely separable.

  The container in the present invention may be a container of another form such as a bottle container. The foaming tool 1B of 2nd Embodiment of this invention is equipped with the bottle container 2B as the container 2, as shown in FIG. A bottle container 2B shown in FIG. 5 has a bottle-shaped container body 20 having a mouth part, a body part, and a bottom part, and is detachably attached to the mouth part of the container body by screwing so that an opening at the upper end of the mouth part is formed. It consists of a cap 26B that opens and closes. In the bottle container 2B, although not shown, a partition for holding the foaming member 3 and the foaming liquid in a separated state is provided. The partition may be a partition wall or a small bag accommodated in the bottle container 2B. Also in the foaming tool 1B of 2nd Embodiment, the liquid which has foamability, and the foaming member 3 by pressing the trunk | drum of the container main body 20 which is a press deformation part by hand, and lose | disappearing the function of a partition. Can be brought into contact with each other, and fine bubbles can be generated by repeating the press deformation.
