Description

  The present invention relates to a sponge scrubbing used for washing the body and dishes.

  In cleaning with scrubber, the quality of detergent foaming affects the cleaning power. For this reason, various scourers with improved foaming properties have been proposed (see Patent Documents 1 and 2).

  The kitchen cleaner described in Patent Document 1 has a sponge disposed at the center of a wound body in which synthetic resin nets are bundled. This cleaner improves the inclusion of detergent and foaming by adding a sponge portion with excellent water absorption to a net lacking water absorption.

The sponge scrubber described in Patent Document 2 has a three-layer structure, and a hole having a diameter larger than that of the first layer is provided in the intermediate layer. The detergent injected from the small-diameter hole of the first layer is held inside the large-diameter hole of the intermediate layer, thereby preventing the detergent from flowing out and improving foaming in the intermediate layer having a large cell size.
Utility Model Registration No. 3100473 No. 7-47090

  However, the kitchen cleaner of Patent Document 1 is easy to flow when foam is dispersed in the net even if foamed in the sponge portion, and foaming during cleaning is insufficient. The sponge scissors of Patent Document 2 have a complicated structure because holes of different diameters are provided in two sponge layers and three layers are laminated and integrated.

  The present invention has been made in view of the above-described situation, and an object of the present invention is to provide a sponge scrubbing having a simple structure and good foaming.

  That is, the sponge scissors of the present invention have the configurations described in [1] to [3] below.

  [1] Sponge scrubber characterized in that a foaming sponge body having a small relative bubbles and excellent liquid retention characteristics is provided in the center of at least one side of the sponge body.

  [2] Sponge scrubber according to the preceding item 1, wherein the foaming foam body is provided with a detergent filling recess.

  [3] Sponge scrubbing according to 1 or 2, wherein the sponge main body is a two-layer laminate, and the foaming sponge body is fitted into only one layer.

  According to the invention of [1], since the detergent and air are mixed with the small bubbles of the foaming sponge body in the center and foamed, and the foam is dispersed in the large bubbles of the sponge body, foaming and foaming are good. Moreover, since the foaming sponge body with small bubbles is only in the central part and the periphery is a sponge body having large bubbles, water drains after use and drying can be accelerated.

  According to the inventions [2] and [3], foaming is particularly good.

  1 and 2 are an overall perspective view and a cross-sectional view showing an embodiment of the sponge scrubber of the present invention.

  The sponge scrubber (1) is composed of a sponge body (10) and a foaming sponge body (20) fitted on one side of the sponge body (10).

  The sponge body (10) has a two-layer structure in which a first layer (11) and a second layer (12) are bonded together. A through-hole is formed in the center of the first layer (11), and a bottomed recessed recess (13) is formed by bonding the first layer (11) and the second layer (12) together. ing.

  A through-hole is also formed in the central portion of the foaming foam body (20), and is fitted into the recessed portion (13) for fitting the sponge body (10) to form a bottomed detergent filling concave portion (21). ing.

  The sponge body (10) and the foaming sponge body (20) are both made of foamed resin, and the bubbles in the foaming sponge body (20) are relatively smaller than the bubbles in the sponge body (10). Yes. The sponge body (10) and the foaming sponge body (20) are both water-permeable and liquid-retaining, but the foaming sponge body (20) having small bubbles is relatively difficult for liquid to flow out. The liquid retention is good, the sponge body (10) having large bubbles can contain a relatively large amount of foamed foam, and has high water permeability.

  Although the present invention does not limit the bubble size of the sponge body (10) and the foaming sponge body (20), the bubbles of the sponge body (10) are 1 to 8 mm in diameter, and the bubbles of the foaming sponge body (20) are 0.1-1 mm is preferable. Further, in the foaming sponge body (20), it is also preferable that large bubbles are mixed as long as liquid retention can be ensured by small bubbles. This is because, when large bubbles are mixed, foaming is improved by promoting mixing of the detergent and air.

  The type of foamed resin that constitutes the sponge body (10) and the foaming foam body (20) is not limited, and examples include foamed polyurethane, foamed polyethylene, EVA (ethylene-vinyl acetate copolymer), and the like. What is necessary is just to make it foam to size.

  In the sponge scrubber (1), when detergent is filled in the detergent filling recess (21) and included in the foaming sponge body (20) and repeatedly compressed and released, the detergent and air are mixed and foamed, The foam is dispersed in the sponge body (10) of the second layer (12) laminated with the surrounding first layer (11). Since the detergent is dispersed in a foamed state in the sponge body (10), the foam can be held without flowing out, and a large amount of foam can be held in relatively large bubbles. For this reason, foaming is good and foam is also good. Further, since the foaming foam body (20) with small bubbles is only at the center portion and the surrounding is the sponge body (10) having large bubbles, the water drainage after use is good and drying can be accelerated.

  In addition, the sponge scrubber of the present invention is obtained by inserting a foaming sponge with a small bubble size in the center of the sponge body, and therefore, a simpler structure and better than the three-layered sponge scrubber of Patent Document 2 described above. You can get bubbling.

  The sponge scrubber of the present invention is not limited to the above-described embodiment, and the following modifications are also included in the present invention.

  The foaming sponge body may be provided on both surfaces of the sponge body. For example, it is possible to arrange the sponge body on both sides by making the sponge body into a single layer structure and inserting the foaming sponge body into the penetrating state. Further, when the foaming sponge body is provided only on one side, the foaming sponge body can be provided only on one side by providing a bottomed fitting recess in the one-layer sponge body. However, in order to form a bottomed recessed recess in the sponge body, or to form a bottomed detergent filling recess in the foaming sponge body, the sponge body has a two-layer structure as in the above embodiment. Is easy to manufacture.

  Moreover, although the recessed part for detergent filling of the foaming sponge body is advantageous in order to contain more detergent, this invention does not ask | require the presence or absence of the recessed part for detergent filling.

It is a whole perspective view of one embodiment of sponge scrubber of the present invention. FIG. 2 is a sectional view taken along line 2-2 of FIG.
