Description

  The present invention relates to a cleaning foaming tool (hereinafter simply referred to as a foaming tool) used during face washing and the like, and a method for manufacturing the same.

  In recent years, facial soaps and body soaps are increasingly used in liquid or powder form instead of solid ones. When using these facial soaps, etc., it is required to make a large amount of fine bubbles. However, in the method of rubbing face soap with a palm and lathering, or the method using a towel, the bubbles become large and the amount thereof is not sufficient.

In order to solve this, a sponge product for foaming is proposed in Patent Document 1, for example. Patent Document 2 proposes a foaming net in which a hygroscopic elastic body is housed in a double-structured bag member made of a net.
JP 2004-33794 A Utility Model Registration No. 3071693

  However, since the entire foaming tool described in Patent Document 1 is composed of one substantially spherical foam, it is difficult for soap and water to be taken into the center, resulting in a sufficient amount of foam. Hard to stand. For this reason, although the foaming tool which materialized this patent document 1 uses the foam with a big bubble cell, when it does in this way, a water | moisture content cannot be hold | maintained and it is also hard to foam. For this reason, the actual product approximate to Patent Document 1 is provided with a moisture retaining sheet integrally on a part of the outer peripheral surface so that moisture is not dripped from the foam. Not only is the production difficult, but the water drainage is deteriorated, which is not preferable for hygiene.

  In Patent Document 1, since the outer peripheral surface is a simple spherical surface, it is difficult to hold soap or the like on the outer peripheral surface. For this reason, a holding hole for holding soap or the like is provided in a part of the outer peripheral surface. However, it is cumbersome and difficult to put soap in this small hole.

  Furthermore, the foaming net described in Patent Document 2 has a simple mesh structure as the bag member, and the mesh size is about 1 mm. However, in such a bag member, since the mesh size is inappropriate, the foaming function is insufficient. In order to solve this problem, in the foaming net described in Patent Document 2, the bag member has a double structure, but actually, the bag members move relative to each other to maintain the foaming function and the foam. The function is still poor.

  An object of the present invention is to provide a foaming tool that can solve the above-described problems and can produce a large amount of fine bubbles and is easy to manufacture.

  In order to achieve the above object, in the invention relating to the cleaning foaming device, a cleaning in which a plurality of soft synthetic resin foam blocks are accommodated in a storage bag made of a porous water-permeable sheet made of soft synthetic resin. In the foaming device, the housing bag is formed into a bag shape by bonding a part of the water-permeable sheet to each other, and the density of the number of bubble cells in the foamed block is the density of the number of bubble cells in the water-permeable sheet. It is characterized by higher than.

  According to a second aspect of the present invention, in the first aspect of the present invention, the number of bubble cells in the water-permeable sheet is within a range of 10 to 40 per inch, and the number of cells in the foam block is 25 per inch. It is characterized by being in a range of ˜60.

The invention described in claim 3 is characterized in that, in the invention described in claim 1 or 2, the foamed block is subjected to film removal treatment.
In invention of Claim 4, in the invention as described in any one of Claims 1-3, the said foaming block is a rectangular parallelepiped shape, It is characterized by the above-mentioned.

  The invention according to claim 5 relating to the method for producing a cleaning foaming device, wherein the foaming device for cleaning has a plurality of foam blocks accommodated in a storage bag made of a sheet including at least one porous water-permeable sheet. In the manufacturing method of the above, the foam block is accommodated inside the sheet with the sheet recessed in the cylindrical body and with the edge of the sheet protruding outward from the upper end of the cylindrical body Then, another sheet is polymerized on the sheet so as to close its upper end opening, and the two sheets are bonded to each other.

  Therefore, in this invention, if the soap made from a liquid or powder is sprinkled on the foaming device and the foaming device is given up, bubbles are generated by the foam block and the bubble cell of the containing bag. In this case, since there is a space between the containing bag and each foam block and between each foam block, air is efficiently involved and a large amount of fine bubbles are generated. In addition, since the density of the bubble cells in the foam block is higher than the density of the bubble cells in the storage bag, fine bubbles are generated, and the bubbles are not disturbed via the large bubble cells in the storage bag, and can be smoothly externalized. Get out. In manufacturing the storage bag, for example, two water-permeable sheets may be integrated by bonding, which is simple.

  As described above, in the present invention, a large amount of fine bubbles can be produced, and a foaming tool can be easily produced.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying the present invention will be described below with reference to FIGS. The cleaning lather 11 of this embodiment includes a storage bag 13 (within a maximum inner diameter of about 30 to 100 mm, for example, an inner diameter of 70 mm) made of a porous water-permeable sheet 12 made of soft polyurethane, and the storage bag 13. It is composed of a plurality of (about 5 to 15, for example, 10) foamed blocks 14 made of the same flexible polyurethane (size of about 5 to 20 mm square, for example, 10 mm). The number of bubble cells in the foam block 14 is in the range of 25 to 70 per inch, and the number of bubble cells in the water-permeable sheet 12 is 10 to 40 per inch. Therefore, the density of the bubble cells of the foam block 14 is higher than the density of the bubble cells of the water-permeable sheet 12 of the containing bag 13.

  The water flow sheet 12 includes a substantially hemispherical first water flow sheet 12a and a flat second water flow sheet 12b. The 2nd water flow sheet 12b is arrange | positioned so that the opening part of the 1st water flow sheet 12a may be block | closed, and these 12a, 12b is mutually adhere | attached by melt | fusion. The 1st water flow sheet 12a and the 2nd water flow sheet 12b consist of a water flow sheet of the same material, and the film removal process is given to those bubble cells by well-known explosion processing, chemical processing, etc.

  The foam block 14 has a cubic shape, and a film removal process is performed on the bubble cell by a well-known explosion process or chemical process. In addition, as the foam block 14, a plurality of different colors are used.

And the ratio of the space with respect to the volume of the said accommodation bag 13, ie, the ratio (it makes this porosity) remove | excluding the whole volume of the foam block 14 from the said volume, is in the range of 5%-45%.
Next, the manufacturing method of the washing | cleaning foaming tool 11 comprised as mentioned above is demonstrated based on Fig.4 (a)-(d).

  First, as shown to Fig.4 (a), the 1st water flow sheet 12a is installed in the upper end opening part of the metal cylindrical body 21 as a cylindrical body. Next, as shown in FIG. 4B, the first water-permeable sheet 12a is pushed into the cylindrical body 21 to form a concave shape, and a plurality of foam blocks 14 are provided in the concave first water-permeable sheet 12a. Accommodate. And the 2nd water flow sheet 12b is superposed | stacked on the 1st water flow sheet 12a so that the upper end opening of the 1st water flow sheet 12a may be closed.

  Next, as shown in FIG. 4C, the first water-passing sheet 12 a and the second water-passing sheet 12 b are pressed against the upper end of the cylindrical body 21 by a metal hot press 22. If it does in this way, the superposition | polymerization part of the 1st water flow sheet 12a and the 2nd water flow sheet 12b will be fuse | fused, and it will mutually adhere | attach. And as shown in FIG.4 (d), if the outer edge part is cut off from the adhesion part of the 1st water flow sheet 12a and the 2nd water flow sheet 12b with the cutter 23, and the foaming tool 11 will be taken out from the inside of the cylindrical body 21 The foaming tool 11 shown in FIG.

As described above, the foaming tool 11 having a substantially hemispherical shape can be easily manufactured with simple equipment without requiring a troublesome work such as sewing.
In the case of using the whistling tool 11 manufactured in this way, after soaking water or hot water in the whistling tool 11 and giving moisture, the soap of liquid or powder is sprinkled on the whistling tool 11, If the foaming tool 11 is given up, bubbles are generated by the foam blocks 14 and the bubble cells of the containing bag 13. In this case, since the plurality of foam blocks 14 are accommodated in the accommodation bag 13, small spaces are scattered between the accommodation bag 13 and each foam block 14 and between each foam block 14. The sum of these spaces constitutes the aforementioned porosity. For this reason, air is efficiently entrapped in the foam block 14 together with the soap, and a large amount of fine bubbles are generated, and the generated bubbles are maintained in the space. That is, as the foaming tool 11 is rubbed, bubbles are continuously generated and the bubbles come out through the space and the bubble cell of the containing bag 13. In this case, since the density of the bubble cells in the foam block 14 is high and the density of the bubble cells in the storage bag 13 is lower than that, fine bubbles are mainly generated by the foam block 14 as described above. Go out smoothly without being disturbed by. In addition, since air and moisture inside and outside the storage bag 13 smoothly enter and exit, bubbles can be generated efficiently.

  As described above, since there is a space between the foam blocks 14 and air is easily caught in the foam blocks 14, a foam cell having a small bubble cell can be used. For this reason, fine bubbles are formed as described above. Since the foam block 14 can use a small bubble cell, the foam block 14 can effectively hold a large amount of moisture, unlike the conventional case, the trouble of draining water immediately and always replenishing moisture is not necessary. Absent. Moreover, since the water-permeable sheet 12 and the foamed block 14 of the containing bag 13 are subjected to the film removal processing of the bubble cells, the opening ratio of the bubble cells occupying the whole can be increased. For this reason, the quantity which can hold | maintain a soap and a water | moisture content can be increased, and also the inflow / outflow amount of air can be increased and a bubble can be generated efficiently. Moreover, since the open area ratio of the bubble cell is high, the water is appropriately drained and is hygienic.

  In addition, since there is a space between the foam blocks 14, a large amount of bubbles can be generated even if the foam blocks 14 having relatively high rigidity and elasticity are used. For this reason, by using the highly foamed block 14 rich in elasticity, it is possible to obtain the foaming tool 11 having excellent shape restoring force, and the work of gripping the foaming tool 11 is made to respond effectively to the movement of the hand. Can be done.

  In addition, since the storage bag 13 is formed by integrating the two water-permeable sheets 12a and 12b by adhesion, unlike the above-described conventional one, the gap between them does not open, and the internal foam block 14 is exposed to the outside. Never come out.

  Furthermore, as apparent from FIG. 1, the foam block 14 inside is seen through the bubble cell of the containing bag 13 as if it was sandwiched through the lace curtain. By using a different color from the bag 13 and using a plurality of colors, the whistling tool 11 having an excellent appearance can be obtained.

The effects of the embodiment described above are as follows.
-The whistling tool 11 which makes a substantially hemispherical shape can be easily manufactured with simple equipment.
・ It is possible to generate fine bubbles efficiently in large quantities. In this case, since the number of bubble cells in the containing bag 13 is in the range of 10 to 40 per inch, a large amount of fine bubbles can be generated in combination with the film removal process. In addition, since the foam blocks 14 are in the range of 25 to 70 per inch, a large amount of fine bubbles can be generated in combination with the film removal process in the same manner as the storage bag 13.

  The water flow sheet 12 includes a substantially hemispherical first water flow sheet 12a and a flat second water flow sheet 12b. The 2nd water flow sheet 12b is arrange | positioned so that the opening part of the 1st water flow sheet 12a may be block | closed, and these 12a, 12b is mutually adhere | attached by melt | fusion. The 1st water flow sheet 12a and the 2nd water flow sheet 12b consist of a water flow sheet of the same material, and the film removal process is given to those bubble cells by well-known explosion processing, chemical processing, etc.

  The foam block 14 has a cubic shape, and a film removal process is performed on the bubble cell by a well-known explosion process or chemical process. In addition, as the foam block 14, a plurality of different colors are used.

And the ratio of the space with respect to the volume of the said accommodation bag 13, ie, the ratio (it makes this porosity) remove | excluding the whole volume of the foam block 14 from the said volume, is in the range of 5%-45%.
A large amount of moisture can be retained in the foam block 14, and the trouble of constantly replenishing moisture can be eliminated.

  -Since the water-permeable sheet 12 and the foam block 14 of the containing bag 13 are subjected to the film removal treatment of the bubble cell, the opening ratio of the bubble cell can be increased, and the amount of soap and moisture that can be retained can be increased. At the same time, the water is moderately drained and can be used hygienically.

-It can be set as the foaming tool 11 rich in elasticity, and the work which rubs the foaming tool 11 can be performed effectively.
The internal foam block 14 does not come out of the storage bag 13.

  -The whistling tool 11 having an excellent appearance and high commercial value can be obtained.

  Table 1 shows the experimental results of the example and the comparative example. Here, in Examples 1 to 9, for example, polyurethane foam product number “MF-30” manufactured by Inoac Corporation was used as the elastic sheet of the containing bag 13. This “MF-30” has a thickness of 3 mm and has been subjected to film removal treatment. As shown in Table 2, in the example and the comparative example, the storage bag 13 made of a plurality of types of elastic sheets having different densities and the number of cells per unit length is used. In Examples and Comparative Examples, those shown in A, E, and G of Table 2 are used. The foam block is made of the same material as that of the housing bag 13.
