Abstract

PROBLEM TO BE SOLVED: To make a sponge scrubber hard to slip through a picking hand.SOLUTION: A sponge scrubber 1 is composed of three layers, with an intermediate layer 2 made to have a relatively softer characteristic than both surface layers 3, 4. To be concrete, in Fig. 2, the intermediate layer 2 and one surface layer 3 are formed of a sponge layer, with the other surface layer 4 formed of non-woven fabric. Further, the intermediate layer 2 is formed softer than the surface layer 3 in the size of bubbles and the material. The surface layer 4 is laminated with a reinforcement layer 42 on the surface side of a non-fabric base cloth 41, with scrubber bristles 43 projected from the rear face by means of a napping process by needle punch and hardened with an adhesive. Consequently, when the opposing sides 11, 12 of the sponge scrubber 1 are picked with fingers 91, 92 stuck with detergent, the softness of the intermediate layer 2 in the three layers makes the fingers 911, 921 catch the intermediate layer 2, preventing the sponge scrubber 1 from slipping away in the direction of the arrow 93.SELECTED DRAWING: Figure 2

  Here, for example, when a bathtub is washed, the sponge scrubbing for it tends to become large so that a relatively large area is rubbed at once. In that case, especially for a woman or the like, the sponge scrubbing is larger than the hand size. For example, as shown in FIG. Slips with detergent and escapes (cannot be grasped) as shown by arrow 107. Moreover, even if the hand is large like a man and the fingers 91 and 92 are U-shaped as shown in FIG. 6A and the sponge scoop 101 is gripped in parallel by the fingertips 911 and 921, When a force is applied for gripping, the sponge scoop 101 is bent as shown in FIG. 6B, and as a result, it escapes from the fingertips 911 and 921.

  An object of the present invention is to provide a sponge scrubber that can be fingered and easily removed and polished.

  The sponge scrubber of the present invention is composed of three layers of sponge layers having different properties from each other or a nonwoven fabric layer laminated on the sponge layer, and the intermediate layer is relatively softer than both surface layers. It is a property.

  According to the above configuration, in sponge sponges having different properties from each other, for example, sponge layers having different bubble sizes and hardness, or sponge layers obtained by laminating a nonwoven fabric layer on sponge layers, there are three layers, and intermediate layers are formed on both surfaces. The property is relatively softer than the layer. For example, the intermediate layer can be made softer by changing the size and material of the air bubbles on one surface layer, or the other surface layer can be made of non-woven fabric and hardened with an adhesive to form harder than the intermediate layer. It is.

  Therefore, when the opposite side of the sponge scrubbing is picked with a finger with a detergent, the size of the hand is particularly large for women, etc., unless the finger is in a U shape or the ends of the U shape are folded inward. If the sponge scrubbing is large and the finger scoops out, the sponge scrubbing slips away with the detergent and cannot escape (cannot be gripped). Such problems can be eliminated. As a result, the sponge scrubbing can be easily rubbed against an object to be cleaned such as a bathtub to remove dirt or polish it.

  Further, in the sponge scrubber of the present invention, the other surface layer includes a base fabric made of the nonwoven fabric and a reinforcing layer laminated on the surface side of the base fabric, and a raising process by a needle punch from the back surface of the base fabric. It is characterized by comprising a comb hair protruding from the reinforcing layer.

  According to said structure, the base end side of the lashes by a needle punch is hardened by the said adhesive agent at the base fabric and the reinforcement layer.

  Therefore, even if the other surface layer is thinner than the one surface layer, the other surface layer can be formed to be hard, and finger engagement on the other surface layer side can be improved. Further, the effect of scrubbing dirt can be enhanced by the lashes and the reinforcing layer on the surface solidified with an adhesive.

  Preferably, a pattern is printed on the base fabric and the reinforcing layer made of the nonwoven fabric.

  According to said structure, since the said other surface layer consists of a comparatively fine non-woven fabric in which a lash is raised, it prints a pattern difficult with a sponge etc. using it.

  As a result, the commercial value of the sponge sponge can be increased.

  Furthermore, in the sponge scrubber of the present invention, the whole is formed in a substantially rectangular shape, and has a concave portion that is recessed inward from the side so as to face the vicinity of the middle position in the longitudinal direction of a pair of sides that are substantially parallel to each other. It is characterized by.

  According to said structure, in addition to being easy to hold | grip because the intermediate | middle layer is soft with three layers as mentioned above, the recessed part is provided in the opposing position of a side.

  As a result, the concave portion serves as a guide for placing the finger, and the finger to which the detergent is attached becomes more difficult to slip.

  Further, the sponge scrubber of the present invention is characterized in that the whole is formed in a substantially rectangular shape, and a long hole extending in the diagonal direction is formed in the vicinity of the corner portion through the three layers.

  According to said structure, without using a hanging string etc., this sponge scrub can be directly hung on the hook provided in the wall surface etc., and can be stored and dried. Further, when the hook-shaped hook passes through the long hole, the long hole is along the direction of the standing of the hook, and when the hook extends vertically, the sponge scrubbing is inclined diagonally, that is, diagonally. It is kept in a state, and draining and drying can be performed quickly.

  Preferably, the whole is substantially rectangular and has a width of 7 to 8 cm.

  According to said structure, even if it is a rectangle and a width | variety is 7-8 cm, even a woman with comparatively small hand can hold firmly.

  Furthermore, the sponge scrubber of the present invention is characterized in that the whole is formed in a substantially rectangular shape, and an arch-like cut is formed on the side surface which becomes the bottom when the sponge is erected in the vertical direction.

  According to the above configuration, when storing the sponge scrubbing in a state where it is stood on the upper surface of the sink or the like, if the side surface serving as the bottom portion is flush, the moisture is between the entire bottom portion and the upper surface of the sink. In contrast to being stored by surface tension, the arch-shaped cuts are formed, so that moisture approaches the leg portions on both sides of the arch.

  Therefore, draining and drying can be performed quickly.

  As described above, the sponge scrubber of the present invention has three layers so that the intermediate layer is relatively softer than both surface layers.

  Therefore, even when the opposite side of the sponge scrubbing is picked with a finger with a detergent, it is possible to eliminate such a problem that the finger gets caught on the soft intermediate layer and the sponge scrubbing slips away with the detergent. Thus, the sponge scrubbing can be rubbed against the object to be cleaned such as a bathtub to easily remove or polish it.

It is a perspective view of sponge sponge concerning one embodiment of the present invention. It is a figure for demonstrating the expanded cross section and usage method of sponge scrubbing shown in FIG. 1 is a perspective view of a typical prior art sponge scrubber. FIG. It is a perspective view of another conventional sponge scrubber. It is a figure for demonstrating the problem of sponge sponge shown in FIG. It is another figure for demonstrating the problem of sponge scrubbing shown in the said FIG.

  FIG. 1 is a perspective view of a sponge scrubber 1 according to an embodiment of the present invention. This sponge scrubber 1 is composed of three layers, and the intermediate layer 2 is characterized by being relatively softer than the two surface layers 3 and 4. In the present embodiment, the intermediate layer 2 and one surface layer 3 are formed of a sponge layer, and the other surface layer 4 is formed of a nonwoven fabric. Sponge scrubber 1 is formed in the form of a sheet-like body after each layer 2, 3 and 4 is individually laminated, and is die-cut to form the shape shown in FIG.

  The intermediate layer 2 and the surface layer 3 are made of an elastic porous material having open cells, such as polyurethane (urethane resin), melamine, and polystyrene. For example, when the intermediate layer 2 and the surface layer 3 are made of polyurethane, the preparation is mainly composed of a polyol and an isocyanate, and a foaming agent, a foaming agent, a catalyst, a colorant, and the like are mixed, and in parallel with the resinification. And then foaming.

  In order to make the difference in hardness (softness), the difference in the number of cells between the intermediate layer 2 and the surface layer 3, that is, the number of bubbles, and the difference in hardness between the main component, that is, the material itself. Can respond. Here, the “number of cells” refers to the number of bubbles (cells) per unit length (25 mm) of the elastic porous material (based on JIS K6400). As the number of cells increases, bubbles become finer and clogged. The number of cells is a value measured and calculated by counting the number of cells included in a predetermined section of the elastic porous material with a microscope or the like. In the present embodiment, the thickness H2 of the intermediate layer 2 is about 22 mm, and the thickness H3 of the surface layer 3 is about 14 mm.

  On the other hand, the surface layer 4 is formed of a non-woven fabric and hardened with an adhesive so as to be harder than the intermediate layer 2 and the surface layer 3 in order to make the difference in hardness described above. The FIG. 2 is an enlarged cross-sectional view of the sponge scrubber 1 and a view for explaining how to use it. The surface layer 4 includes a base cloth 41 made of non-woven fabric and a reinforcing layer 42 laminated on the surface side of the base cloth 41, and comb hairs 43 protruding from the reinforcing layer 42 from the back surface of the base cloth 41 by a raising process by needle punching. It is configured with. And the base end side of the stubble 43 by a needle punch is hardened to the base fabric 41 and the reinforcement layer 42 with the said adhesive agent. Japanese Patent Application Laid-Open No. 2006-77866 is detailed about a method of creating the scalp hair 43 by the needle punch. The surface layer 4 is formed with a thickness H4 of about 7 mm including the hairs 43. In FIG. 2, the surface layer 4 is shown to be thicker than the actual ratio than the other two layers 2 and 3 for easy understanding.

  Therefore, when the opposite sides 11 and 12 of the sponge scrubbing 1 are picked with fingers 91 and 92 with detergent, the intermediate layer 2 is soft with three layers, so that the fingertips 911 and 921 are as shown in FIG. It is possible to prevent the sponge scrubber 1 from escaping in the direction of the arrow 93 on the intermediate layer 2. Thus, the sponge scrubber 1 can be easily rubbed against a cleaning object such as a bathtub to remove dirt or polish it.

  In the above description, the sponge scrubber 1 has three layers. However, it may be a schematic three layers having a relationship of hardness (softness) for realizing the functions as described above. Needless to say, each layer may be composed of a plurality of fine (thin) layers in order to achieve high functionality.

  Further, in the sponge scrubbing 1 of the present embodiment, the surface layer 4 includes a base cloth 41 and a reinforcing layer 42 made of a nonwoven fabric, and a scalp hair 43 protruding from the back surface of the base cloth 41 by a raising process using a needle punch from the reinforcing layer 42. And the base layer side of the stubble 43 is fixed to the base cloth 41 and the reinforcing layer 42 with an adhesive, so that the surface layer 4 can be formed hard even if it is thinner than the surface layer 3 of the sponge, Finger hooking on the surface layer 4 side can be improved. Further, the effect of scrubbing dirt can be enhanced by the lashes 43 and the reinforcing layer 42 on the surface solidified with an adhesive.

  And since the surface layer 4 consists of a comparatively fine nonwoven fabric with which the hair 43 is brushed, the base fabric 41 and the reinforcement layer 42 which are the nonwoven fabric are utilized as shown in FIG. Printing of patterns 45 to 49, which is difficult with sponges, is performed. Thereby, the commercial value of the sponge scrubber 1 can be increased.

  Furthermore, the sponge scrubber 1 of the present embodiment is easy to grip because the intermediate layer 2 is soft with three layers, and the whole is formed in a substantially rectangular shape as shown in FIG. Since the recesses 13 and 14 are recessed inwardly from the side, facing the vicinity of the middle position in the longitudinal direction of the side edges 11 and 12, respectively, the recesses 13 and 14 serve as a guide for applying the fingers 91 and 92. The fingers 91 and 92 to which the detergent is attached become more difficult to slip.

  Further, the sponge scrubber 1 of the present embodiment is generally formed in a substantially rectangular shape, and a long hole 15 extending through the three layers and extending in the diagonal direction is formed in the vicinity of the corner. As a result, it is of course possible to pass a hanging string, but without using a hanging string or the like, the sponge scrubber 1 can be directly suspended from a hook provided on a wall surface and stored and dried. . Further, when the hook-shaped hook passes through the long hole 15, the long hole 15 is along the direction in which the hook stands, and when the hook extends vertically, the sponge scrubber 1 has the diagonal line vertical, That is, it is held in an inclined state, and draining and drying can be performed quickly.

  Furthermore, the sponge scrubber 1 of the present embodiment is formed in a substantially rectangular shape as a whole and has a width W of 7 to 8 cm. This is because a sponge scrubber 1 is rectangular and has a width W of 7 to 8 cm, so that even a woman with a relatively small hand can hold it firmly.

  Further, in the sponge scrubber 1 of the present embodiment, the whole is formed in a substantially rectangular shape, and when standing in the vertical direction, as shown in FIG. ing. Accordingly, when the sponge scrubbing 1 is stored in a standing state on the upper surface of the sink, when the side surface 16 serving as the bottom is flush with the surface, the moisture is placed between the entire bottom and the upper surface of the sink. Whereas the arch-shaped cuts 17 are formed in contrast to the accumulation of tension, the moisture moves closer to the leg portions 18 and 19 on both sides of the arch and drains and dries quickly. Can do.
