(Wrapping material)
The packaging material used in the present invention encloses a foam bath agent, allows bath water to flow into the interior, and releases carbon dioxide gas generated by contact with the bath water that has flowed into the exterior.
The form of the packaging material in the present invention is not particularly limited as long as the above conditions are satisfied. Examples of the packaging material include a bag made of a sheet material having air permeability and water permeability, and a storage container that can accommodate a foamed bathing agent inside.

The bag is configured to have one or more openings or pores through which bath water can be introduced and sufficient to release carbon dioxide generated from the foam bathing agent to the outside. .
If the sheet | seat material which comprises a bag body is a nonwoven fabric, the thing of the basis weight of 20-200 g / m < ² > is preferable, for example, and 30-100 g / m < ² > is more preferable.
If the weight per unit area is a non-woven fabric, the foam bathing agent does not leak to the outside, sufficient carbon dioxide gas is supplied to the bath water, and the foaming time can be greatly extended. Is preferable because it is sufficiently played.

  The size of the bag body may be set as appropriate from the balance with the total amount of the foam bathing agent contained in the bag body, and the amount of bath water flowing into the bag body and the contact amount between the bath water flowing in and the foam bathing agent. What is necessary is just to decide so that a certain amount of space | gap may be provided so that balance may be taken, sufficient carbon dioxide gas may be supplied to bath water, and foaming time may be extended significantly.

  The shape of the bag body is not particularly limited, and for example, a spherical shape, a hemispherical shape, a conical shape, a three-dimensional shape such as a polygonal pyramid shape greater than or equal to a triangular pyramid, a cubic shape, and a rectangular parallelepiped shape, or a thin body only in the bag shape. , Three-dimensional when encapsulating foam bathing agent, for example, a sealed bag type with sealed sides, a standing pouch type that allows the bottom to be self-supporting, and a gusset type with gusseted sides and bottom And a foldable bag shape.

  The sheet material constituting the bag is not particularly limited as long as it has air permeability and water permeability and can easily pass carbon dioxide gas. For example, a nonwoven fabric, a woven fabric, a mesh (net) -like synthetic material is used. A resin sheet etc. are mentioned, The bag body comprised by the nonwoven fabric among these is preferable for said reason.

Further, the storage container has at least one opening, and is configured to allow the bath water to flow into the inside through the opening and to release the carbon dioxide gas generated by contact with the bath water that has flowed into the outside. .
As a form of the storage container, for example, as shown in FIG. 3, a container 2 including a cylindrical container main body 21 and a lid 23 provided with a part of an opening 25 is cited. The shape and size of the opening 25 are appropriately determined so that bath water can flow into the container 2 and carbon dioxide gas generated from the foam bath 3 can be released to the outside of the container 2. When this container 2 is used, the foamed bath agent 3 can be accommodated as it is in the container 2 without being put in the bag as described above, and the foamed bath agent 3 and a weight as a sedimentation means described later. 5 may be accommodated.

In the form shown in FIG. 3, the opening 25 is provided at one place on the lid 23, but two or more openings may be provided. Further, the opening 25 can be provided in the container main body 21 in addition to the lid 23.

As a method for forming the opening, specifically, a method is adopted in which a small cut is made from the side in the vicinity of the corner of the bag, and the corner of the bag is cut off from the cut at the time of use. There is a method of forming a hole (opening) having a size of 2 mm, closing the hole with a non-water-permeable film seal or the like, and peeling off the seal at the time of use. In addition, when the hole is formed on the surface of the bag body, if the hole is covered with the above-described nonwoven fabric or the like, the amount of carbon dioxide released can be adjusted and the foaming time of the foaming bath agent can be extended longer. Is possible.

(Settling means)
The present invention is characterized in that the packaging material containing the foamed bathing agent is completely immersed in the bath water. By completely immersing the packaging material, it is possible to prevent the carbon dioxide gas from being released into the air, and an appropriate amount of carbon dioxide is accumulated in the packaging material so that the carbon dioxide gas can be sufficiently supplied into the bath water.
If the packaging material is not completely submerged, carbon dioxide due to foaming does not accumulate in the packaging material, and foaming due to bath water flowing into the packaging material cannot be controlled, making it difficult to extend the foaming time. A part of the carbon dioxide gas that escapes escapes into the air, and the dissolution efficiency of the carbon dioxide gas in the bath water may deteriorate.
Examples of the sedimentation means for completely immersing the packaging material containing the foamed bathing agent in the bath water include a weight, a locking member, and an outer container.

The weight is not particularly limited as long as it is a material having a specific gravity sufficient to allow the packaging material to settle in the bath water, and examples thereof include ceramics, various rocks, metals, and clays. By storing the weight in the packaging material or by connecting the packaging material and the weight, the packaging material can be completely immersed in the bath water.
When the packaging material is a bag as described above, in order to completely immerse the bag in bath water, for example, at least one weight made of ceramics and a foamed bathing agent are allowed to coexist in the bag. Thus, the bag body can be completely immersed in the bath water. Alternatively, one or more weights may be connected to the outside of the bag body, and the bag body may be completely immersed in the bath water.
The same applies to the case where the packaging material is a container as shown in FIG. 3, and a foam bathing agent and a weight may be placed in the container body.

  In addition, examples of the locking member include a suction cup. By connecting the packaging material and the suction cup and adsorbing the suction cup to an arbitrary place of the bathtub, the packaging material can be completely immersed in the bath water.

  The outer container as used in this invention means the container which can accommodate a packaging material in the inside, and does not prevent inflow of bath water, and has mass sufficient to settle in bath water. For example, the outer container is configured by combining lattices to such an extent that the inflow of bath water is not hindered, and a bag body containing the foamed bathing agent is accommodated. By making the outer container with a material having a specific gravity sufficient to settle it in the bath water, the bag body can be completely immersed in the bath water. Alternatively, if the outer container alone does not settle into the bath water, a weight as described above may be installed in the outer container, and the bag body may be completely immersed in the bath water.
