Description

  The present invention relates to a laminated washing tool with a sponge used for dishwashing, bathing, and other washing.

  Conventionally, as a simple washing tool used at home and in the industry, sponge is used alone or in a laminated state by joining with a porous soft material layer for rubbing, such as sponge or nonwoven fabric laminate, which has superior rubbing power. Yes. This sponge is a foam, and has a large number of through-holes dispersed and arranged by continuous bubbles, so that the air permeability and water permeability are good. In use, when a detergent is applied to the sponge of the washing tool and the dirt such as tableware is rubbed, the sponge is swollen and the detergent and air are distributed in many through pores. And if the frictional force by the deformation | transformation and the return | restoration of sponge adds to the detergent and air in a hole from each pore inner wall, respectively, detergent can remove dirt, such as foaming tableware.

However, if only a general sponge is used for the washing tool, the foaming of the detergent is insufficient and the foam does not occur densely, so that satisfactory foaming cannot be obtained. Therefore, as a cleaning tool that has much better detergent foam and denser foam than sponge, for example, a bath cloth in which a core cloth made of several layers of diamond knitted cloth and a porous soft material layer are bonded together is presented. (See Patent Document 1). In addition, in order to increase the cleaning ability of the cleaning tool using a sponge, for example, the object to be cleaned is sandwiched in a dishwasher formed by laminating a sponge and a nonwoven fabric laminate. The sponge is formed in two upper and lower layers, and a plurality of through-holes having a diameter of 0.5 to 2.0 cm leading from the surface of the sponge to the surface of the nonwoven fabric laminate (2 or 4 in the embodiment) ) Is provided (see Patent Document 2).

  However, the former cleaning tool that does not use a sponge is complicated in structure, and thus tends to be expensive. In this regard, in the latter cleaning device using a sponge, the sponge and the nonwoven fabric laminate are bonded together, and a cut surface is provided from one side in the longitudinal direction of the sponge to the substantially central portion, so that one side half of the sponge is moved up and down. Cut into two layers and have through-holes in the side that lead from the surface of the sponge to the surface of the non-woven laminate, 3 in 4 in one embodiment, or all 2 in another embodiment is doing. Therefore, in the latter washing tool, the cut surface provided on one side surface of the sponge is provided with a structure that can smoothly transfer the detergent, but naturally no satisfactory foaming can be performed on the other side surface.

  The present invention has been made by paying attention to such conventional problems, and the whole sponge is easily deformed greatly, and the whole sponge easily contains a large amount of detergent and a large amount of air. An object of the present invention is to provide a hygienic laminated washing tool with a sponge that is suitable for washing in a narrow place by improving the deformation performance and foaming performance, is easy to dry, and is difficult for germs to propagate.

  In order to achieve the above-mentioned object, the laminated washing tool with a sponge according to the present invention is provided with a large number of through-holes dispersed throughout the sponge extending from one main surface of the sponge to the other main surface. The diameter of each through-thick hole is made larger than the diameter of a large number of through-holes formed by continuous bubbles and dispersed throughout the sponge. Then, a porous soft material layer is bonded and laminated to one of the main surfaces of the sponge, and the opening of each through-hole facing the inner main surface of the sponge is closed with the porous soft material layer.

  Further, it is preferable that the diameter of the through-thick hole is 1 to 5 mm.

  Further, the laminated cleaning tool with a sponge in a net bag according to the present invention is a linear structure that forms a net at the opening of each through-hole facing the outer main surface of the sponge constituting the cleaning tool. Store in a net bag that can stretch your body.

  Compared to the case where a general sponge in which only a large number of through-holes are dispersed and arranged is used as it is, the laminated cleaning tool with a sponge according to the present invention has a large number of through-pores in the entire sponge and the sponge. A large number of through-holes extending from one main surface to the opposite main surface are dispersed and arranged, so that a large amount of detergent and a large amount of air are taken in and dispersed throughout the entire sponge. Can be included.

  Then, a porous soft material layer is bonded and laminated to one of the main surfaces of the sponge, and the opening of each through-hole facing the inner main surface of the sponge is closed with the porous soft material layer, thereby dispersing the entire sponge. A large amount of the detergent contained can hardly move to the porous soft material layer and can be temporarily held in the sponge. Therefore, the detergent does not leak rapidly from the washing tool. In addition, since the sponge has elasticity and a large number of through-holes are dispersed throughout the sponge, if the sponge is rubbed by hand, the entire sponge can be greatly deformed, and the entire deformation of the sponge and the original It can be easily done by repeatedly returning to the shape. For this reason, even if the washing tool in which the porous soft material layer is joined to the sponge by hand, naturally the entire washing tool can be greatly deformed, and the entire washing tool can be easily deformed and returned to its original shape easily. . Therefore, the laminated washing tool with sponge is excellent in deformation performance.

  At the time of use, apply detergent to the sponge, especially the washing tool, soak a lot of detergent and a lot of air in the large number of through holes and through holes that are dispersed throughout the sponge, Deform the washing tool greatly. Then, since the washing tool is excellent in deformation performance, a large frictional force can be applied to the detergent contained from the inner walls of the through-holes and the through-holes while bringing the air into contact with each other. Therefore, the sponge of the washing tool is excellent in foaming performance, and a large amount of dense foam can be generated over the entire sponge. In addition, when the laminated washing implement with sponge is greatly deformed, the corners of the washing implement can be projected more acutely than other portions. Therefore, it is also suitable for cleaning a narrow place. If a large number of through-holes are dispersed and arranged throughout the sponge, the washing tool becomes easy to dry after washing, and it is difficult for germs to propagate, which is hygienic.

  And, when selecting the hole diameter of the through-thick hole, if the hole diameter is made smaller than 1 mm and reduced, the strength of the sponge and the restoring force after deformation are much lost compared to the sponge having only the through-hole. It becomes easy to keep without. However, the sponge cannot contain a large amount of detergent and a large amount of air, and the entire sponge cannot be greatly deformed. In that respect, when the diameter of the through-thick hole is increased to more than 5 mm, a large amount of detergent and a large amount of air are included in the entire sponge, and the entire sponge can be greatly deformed. However, the strength of the entire sponge and the return force after deformation are both too small.

  Therefore, when the hole diameter of the through-thick hole is 1 to 5 mm, a large amount of detergent and a large amount of air are included in the entire sponge, and the entire sponge can be greatly deformed, and the strength of the sponge and the restoring force after deformation Is easily maintained to a necessary degree. Therefore, deformation performance and foaming performance can be improved while maintaining the strength of the washing tool. Therefore, the laminated cleaning tool with sponge is suitable for cleaning a narrow place.

  In addition, the laminar washing tool with a sponge in a net bag according to the present invention increases the diameter of the through-thick hole and enlarges the opening of the through-thick hole facing the outer main surface of the sponge in order to increase the cleaning power. Even if it is easy to contain a large amount of detergent and a large amount of air in the whole, and the entire sponge is easily deformed greatly, a linear body constituting the net is stretched over the opening, and the linear body is inserted into the hole from the opening. It can be used as an obstacle to foreign matters such as garbage trying to invade. Moreover, if the diameter of the through-holes provided in the sponge is increased, the strength of the entire sponge and the restoring force after deformation are naturally reduced, and the strength of the washing tool is reduced. However, the washing tool is stored in a net bag. As a result, not only can the reduction in the strength of the washing tool be compensated by the net bag making, but the strength and the like can be further increased. Therefore, the strength of the washing tool and the cleaning power can be increased.

The best mode for carrying out the present invention will be described below with reference to FIGS.
FIG. 1 is a perspective view of a laminated washing tool with a sponge to which the present invention is applied, and FIG. This laminated cleaning tool 1 with a sponge is obtained by joining a sponge 2 and a porous soft material layer 3 into a laminated body. Then, as the sponge 2 at the time of production, for example, a flat urethane foam having a length and width of 6 cm, 10 cm, and a thickness of 2 cm is used. Then, a large number of penetrating pores (not shown) having a pore diameter of, for example, 0.5 mm formed by continuous bubbles are dispersedly arranged throughout the sponge 2.

  Therefore, a large number of linear through-holes 6 extending from one main surface (upper surface) 4 to the other main surface (lower surface) 5 are provided in a dispersed manner on the entire sponge 2. The hole diameter is made larger than the hole diameter of the through-hole. For example, with respect to the entire sponge 2, 28 cylindrical through-holes 6 having a hole diameter of 2 mm are disposed so as to be perpendicular to the main surfaces 4 and 5 and the interval between adjacent large-holes 6 is 10 mm. Then, the openings of the 28 through-holes 6 are arranged in a matrix of 4 vertically and 7 horizontally so as to be evenly distributed in a wide central portion of each of the main surfaces 4 and 5. However, the through holes 6 are not provided in the width of the front and rear sides 11 mm and the width of the left and right sides 13 mm of the main surfaces 4 and 5, and the strength of the peripheral portion is increased. In addition to urethane, plastics such as polyethylene, acrylic, styrene, and melamine, natural products, and the like can be used as such sponges. In addition, when a large number of through-holes are distributed throughout the sponge, the openings of the through-holes are widely distributed in the center of the entire surface of each main surface of the sponge and arranged in a spiral, concentric circle, etc. You can also.

  Further, as the porous soft material layer 3, for example, a flat-plate polypropylene nonwoven fabric laminate having a length and width of 6 cm, 10 cm, and a thickness of 1 cm is used. Then, by using the porous soft material layer 3 side at the time of cleaning, it is possible to well rub off dirt with strong adhesion that is difficult to remove even if it is rubbed on the sponge 2 side. In addition to polypropylene, plastics such as polyethylene, polyester, and polyacryl are suitable for the nonwoven fabric laminate as the porous soft material layer. Moreover, you may use a textile laminated body, sponge, etc. as a porous soft material layer.

  One of the main surfaces 4, 5 of the sponge 2, such as the lower surface 5, for example, one of the main surfaces 7, 8 of the porous soft material layer 3, such as the upper surface 7, is overlaid and joined to form a laminate. At that time, the lower surface 5 of the sponge 2 and the upper surface 7 of the porous soft material layer 3 are joined by heat welding, an adhesive, or the like. Then, the opening of each through-hole 6 that faces the lower surface of the sponge 2 can be closed with the porous soft material layer 3, and the laminated washing tool 1 with sponge is completed.

  At the time of use, it is made to adhere to the exposed main surface 4 of the sponge 2 using a liquid, powder or solid detergent. Then, compared with the case where a general sponge in which only a large number of through-holes are dispersed and arranged throughout the sponge is used as it is, through the through-thick holes 6 that are dispersed and arranged in the entire sponge 2 together with the through-holes. A large amount of detergent and a large amount of air can be taken in and dispersed. In addition, when the pore diameters of a large number of through holes dispersed in the porous soft material layer 3 are made small, for example, equal to or smaller than the pore diameters of the through pores dispersed in the sponge 2, Since the through-holes of the respective through-holes 6 facing 5 are closed by the porous soft material layer 3, it is difficult for the detergent to move to the porous soft material layer 3. Therefore, a large amount of detergent can be temporarily held in the sponge 2 of the washing tool 1 and does not leak to the outside rapidly.

  Therefore, when the laminated washing tool 1 with a sponge is rubbed by hand, the sponge 2 has elasticity, and a large number of through-holes 6 are dispersed throughout the sponge 2 so that the entire sponge 2 can be greatly deformed. It is easy to repeat the entire deformation and return to the original shape. For this reason, the entire washing tool 1 in which the porous soft material layer 3 is bonded to the sponge 2 can be greatly deformed, and the entire washing tool can be easily deformed and returned to its original shape. Therefore, the multi-layer cleaning tool 1 with sponge has excellent deformation performance by disposing a large number of through-holes 6 throughout the sponge 2, and based on the elasticity of the sponge 2, the return performance after deformation. Are fully equipped.

  At the time of washing, if the washing tool 1 is rubbed by hand and the whole is greatly deformed, a large number of through-holes 6 distributed throughout the sponge 2 and the detergent contained from the inner walls of the through-pores, A large frictional force can be applied while contacting air. For this reason, the sponge 2 of the washing tool 1 has excellent foaming performance, and a large amount of dense foam can be generated over the entire sponge 2. Moreover, when the detergent contained on the sponge 2 side of the washing tool 1 moves to the porous soft material layer 3 side or the detergent is directly attached to the porous soft material layer 3 side, Naturally, foaming also occurs on the porous soft material layer 3 side. So, when washing the tableware etc., if the laminated washing tool 1 with sponge is greatly deformed, the corners etc. of the washing tool 1 can be projected more sharply than other parts, and it is attached near the bottom of a cup or a dish. It is easy to scrape off dirt. Therefore, the laminated cleaning tool 1 with a sponge is suitable for cleaning in a narrow place. If a large number of through-holes 6 are dispersed and arranged throughout the sponge 2, a large amount of air enters the sponge 2, so that the washing tool 1 can be easily dried after washing and it is difficult for bacteria to propagate. It is so hygienic.

  FIG. 3 is a perspective view of a laminated cleaning tool with a sponge made of net bag to which the present invention is applied. This net-made bag-containing laminated washing tool 9 with sponge is composed of a sponge-containing laminated washing tool 1 and a net-made bag 10 for storing the washing tool 1. Then, as the net bag making 10 at the time of production, for example, a polyester net bag with a square mesh with a side of the mesh 11 of less than 2 mm is used. Then, when the washing tool 1 is stored in the net bag 10, the linear bodies 12 constituting the net can be stretched over the openings of the through-holes 6 facing the outer main surface 4 of the sponge 2.

  Therefore, in order to increase the cleaning power, the diameter of each through-hole 6 is increased, and the opening of each through-hole 6 that faces the outer main surface 4 of the sponge 2 is increased, so that a large amount of detergent is added to the entire sponge 2. Even if a large amount of air is easily contained and the entire sponge 2 is easily deformed greatly, the linear bodies 12 are stretched over the respective openings, and the linear bodies 12 try to enter the holes from the openings. It can be used as an obstacle to foreign matters such as garbage. Moreover, if the diameter of each through-hole 6 provided in the sponge 2 is increased, the strength of the sponge 2 and the restoring force after deformation are naturally reduced, and the strength of the washing tool 1 is also reduced. By storing in the bag, not only can the strength of the washing tool 1 be reduced by the net bag 10, but the strength and the like can be further increased. Therefore, it is possible to increase the strength and the detergency of the laminated washer 9 with a bag made of net-made bags. Therefore, if the length of the laminated washing tool with sponge is further increased and a cylindrical net bag made of a plurality of nets is used to increase the strength as a net bag, the foaming of the washing tool 9 is further improved. And suitable for bathing.

  In the above embodiment, the case has been described in which the diameter of each of the through-thick holes 6 that are dispersedly arranged over the entire sponge 2 that constitutes the washing tool 1 is 2 mm. When the thickness is reduced to less than 1 mm, it becomes easier to maintain the strength of the sponge and the return force after the deformation, as compared with a general sponge having only through pores. However, a large amount of detergent and a large amount of air are contained in the entire sponge, and the entire sponge cannot be greatly deformed. In that respect, when the diameter of the through-thick hole is increased to more than 5 mm, a large amount of detergent and a large amount of air are included in the entire sponge, and the entire sponge can be greatly deformed. However, the strength of the entire sponge and the return force after deformation are both too small.

  Therefore, it is preferable to set the diameter of the through-thick hole to 1 to 5 mm. When the diameter of the hole is set to 1 to 5 mm, the strength of the entire sponge and the restoring force after deformation are relatively easy to maintain, and a large amount of detergent is added to the entire sponge. It is easy to contain a large amount of air, and the entire sponge is easily deformed greatly, and the deformation performance and foaming performance can be improved while maintaining the strength of the washing tool. Therefore, the laminating washing tool with sponge is suitable for washing a narrow place such as near the bottom of a cup or a dish.
