Abstract

An object of the present invention is to prevent clogging of a wiping tool provided with a small hole for assisting foaming.
A plurality of small holes 14 that pass through only between peripheral surfaces 13 of a wiping tool 10 and that allow air to flow therethrough are provided. The openings of the small holes 14 are evenly distributed over substantially the entire circumference of the peripheral surface 13 of the wiping tool 10. Since the upper and lower surfaces 11, 12 that are rubbed against the object to be cleaned are not provided with small holes, the small holes are not clogged with dirt and dust, are hygienic, have good appearance, and foaming performance due to clogging There will be no decrease in When the wiping tool 10 is grasped, a part of the small hole 14 is closed with a finger, but the remaining part remains open, so that the foaming performance is still exhibited. Since the small hole 14 functions as a draining hole after the wiping tool 10 is used, the draining performance is excellent.

Description

  The present invention relates to a wiping tool.

Wiping tools made of a porous material having elasticity made of resin such as resin foam and nonwoven fabric are widely used.
Referring to FIG. 5, this type of wiping tool 20 includes a pair of opposed upper and lower surfaces 21 and 22 and a peripheral surface 23 that connects the peripheral edges of the upper and lower surfaces.
In a normal use state, the upper surface 21 and the lower surface 22 having a large area become wiping surfaces that rub against an object to be cleaned.

  By the way, in general, the wiping tool 20 places importance on the foaming performance. However, in order to improve the foaming of the cleaning agent, it is known that the cleaning agent needs to contain air well.

Therefore, as shown in the figure, a wiping tool 20 in which a large number of small holes 24 are provided on the upper surface 21 and the lower surface 22 has been devised (see Patent Documents 1 and 2). When air enters the small holes 24, the cleaning agent easily contains air and foaming is improved.
In the following, the term “small hole” as used in the present specification is intended to exclude micropores derived from the material (porous body) of the wiping tool, and has a larger pore diameter than micropores derived from such material. Means that.

However, when a small hole is provided on the upper surface or the lower surface that is rubbed against the object to be cleaned in a normal use state, there is a problem that dirt or dust peeled off from the object to be cleaned can easily enter the small hole.
If the small hole is clogged with large dirt or dust in this way, it looks bad and is unsanitary, and air does not easily enter the small hole and the foaming performance is also lowered.

  Therefore, a problem to be solved by the present invention is to prevent clogging of a wiping tool provided with a small hole for assisting foaming.

In order to solve the above problems, the rectangular parallelepiped wiping tool of the present invention has a plurality of small holes that penetrate only between the peripheral surfaces, and the openings of the small holes are distributed over the entire circumference of the peripheral surface. It was meant.
The diameter of the small holes is preferably 2 to 7 mm. The plurality of small holes are preferably arranged in a substantially lattice pattern.
The peripheral surface may be configured with a single surface such as an annular shape, or may be configured with a plurality of surfaces such as a side surface and an end surface.

  In the wiping tool, a plurality of foamed resin layers and / or non-woven fabric layers are laminated between the upper and lower surfaces, and the small holes that pass therethrough are formed on the surface facing one layer of the plurality of layers. It is preferable that the groove is formed by the upper portion being closed by another layer.

Since the wiping tool is provided with a small hole penetrating between the peripheral surfaces, the air can enter the small hole, whereby the foaming performance of the cleaning agent can be improved. In addition, after the use of the wiping tool, the small hole functions as a draining hole that promotes draining.
Furthermore, when using the wiping tool, it will be gripped from the upper or lower surface to a part of the peripheral surface, but the small hole opens almost all the way around the peripheral surface, so that part of it is blocked by the finger. Even if it is done, everything is not blocked. Therefore, air enters the small holes not blocked by the finger, and the foaming performance is exhibited without any problem.

  Since there are no small holes on the upper and lower surfaces of the wiping tool that is rubbed against the object to be cleaned during the cleaning operation, the small holes are not clogged with dirt and dust from the object to be cleaned, and are hygienic and aesthetic. Also good.

  When the wiping tool is formed by laminating a plurality of foamed resin layers, etc., a groove is formed on the outer surface of one layer, and this is blocked by the opposing surface of the adjacent layer except for openings at both ends. If comprised, formation of the small hole which penetrates is easy.

  Hereinafter, embodiments of the invention will be described with reference to the drawings.

The wiping tool 10 of the first embodiment shown in FIGS. 1 and 2 has elasticity suitable for performing a cleaning operation by pressing against an object to be cleaned, and each surface thereof includes a pair of opposed upper and lower surfaces 11 and 12. The peripheral surface 13 connecting the peripheral edges of the upper and lower surfaces.
In addition, a plurality of small holes 14 are formed in a lattice shape inside the wiping tool 10, and the small holes 14 are distributed almost uniformly over the entire circumference of the peripheral surface 13 by penetrating between the peripheral surfaces 13. Is open.

As illustrated, the wiping tool 10 has a substantially heart shape in plan view. Such a shape can be formed by any means such as punching a foamed resin sheet or nonwoven fabric as a material into a heart shape.
Note that the overall shape of the wiping tool 10 is not limited to this, and may be, for example, a prismatic shape or a cylindrical shape. When punching is performed as described above, the shape in plan view can be freely changed.

In a normal use state, the wiping tool 10 holds the entire surface by placing a palm against one of the upper and lower surfaces 11 and 12 (for example, the lower surface 12) and pressing a finger against a part of the peripheral surface 13. , 12 is used as a wiping surface by rubbing against the object to be cleaned.
Since the air enters the small holes 14 opened in the peripheral surface 13, the foaming of the cleaning agent contained in the wiping tool 10 is improved.

  Further, in the wiping tool 10 of the first embodiment, the upper layer 10a and the lower layer 10b, which are porous layers, are laminated in two layers in the thickness direction (up and down direction), respectively. The surfaces are bonded together by appropriate means such as heat fusion.

Both the upper layer 10a and the lower layer 10b are formed of a porous resin elastic body such as a resin foam or a nonwoven fabric. The foaming degree of the foamed resin and the presence / absence and degree of film removal treatment of the foam are not particularly limited.
The type of resin constituting the upper and lower layers 10a and 10b is not particularly limited, and examples thereof include synthetic resins such as polyethylene and melamine, and natural resins such as natural rubber.
For example, when the upper layer 10a is a non-woven fabric excellent in polishing performance and the lower layer 10b is an open cell resin foam excellent in foaming performance, the upper surface 11 is rubbed when the object to be cleaned is very dirty, When the amount is small, the lower surface 12 is rubbed so as not to damage the object to be cleaned.

As shown in FIG. 2, a plurality of grooves 14 extending in a lattice shape are formed on the surface facing the upper layer 10a of the lower layer 10b. The groove 14 is formed by any means such as cutting the lower layer 10b with a cutter (slitter) halfway in the thickness direction. On the other hand, no groove is formed in the upper layer 10a.
Then, the opposing surfaces of the lower layer 10b and the upper layer 10a are bonded to each other by any means such as heat fusion, so that the upper portion of the groove 14 is closed by the upper layer 10a, and both ends of the groove 14 are left open. Thus, the groove 14 constitutes the small hole 14 described above.
When the wiping tool 10 is formed by punching, a groove 14 is formed in one of the two foamed resin sheets used as the material of the upper and lower layers 10a and 10b, and then bonded to the other sheet. When punched into a heart shape, the small holes 14 are naturally opened on the peripheral surface, so that the manufacture is easy.

Here, the hole diameter of the small hole 14 is not particularly limited as long as it is larger than the fine hole derived from the raw material of the wiping tool 10, but if it is too small, the air is difficult to circulate and the foaming performance decreases, and if it is too large. Since the elasticity of a wiping tool falls and polishing performance falls, 2-7 mm is preferable.
The formation mode of the small hole 14 is not limited to the embodiment, and may be formed by punching the peripheral surface 13 of the wiping tool 10. Further, the shape of the small holes 14 is not limited, and may be, for example, round holes or square holes, and the number thereof is not particularly limited.
In the embodiment, the small holes 14 are arranged in a regular lattice shape, but may be arranged in an oblique lattice shape. In short, a plurality of small holes are distributed almost all around the peripheral surface 13 of the wiping tool 10. It is only necessary that the openings are arranged so as to open.
In this embodiment, the small holes 14 are arranged in a single row, but may be arranged in a plurality of rows vertically.
In addition, as long as the openings are distributed almost uniformly over the entire circumference, the arrangement of the small holes 14 does not have to be a lattice pattern, but may be a random network such as a random network.

The wiping tool 10 of 2nd Embodiment is shown to FIG. 3 and FIG.
In this embodiment, the wiping tool is formed of three layers of an upper layer 10a, a lower layer 10b, and a middle layer 10c. A vertical groove is formed on one surface of the middle layer, and a horizontal groove is formed on the other surface. And the small holes 14 are formed.
Here, the small holes 14 in the vertical direction and the small holes 14 in the horizontal direction are not stepped and do not intersect with each other, but are arranged in a lattice pattern in plan view.
About another structure, it is the same as that of 1st Embodiment.

  It should be considered that the embodiments disclosed herein are illustrative and non-restrictive in every respect. The scope of the present invention is defined by the claims for utility model registration, and is intended to include all modifications and variations within that scope.
