Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a dust removing sheet for a drain, which is attached to a drain such as a bath or a washroom or a perforated plate which is attached to the drain to remove dust that flows into the drain.

[0002]

[Prior art]

 Traditionally, grid-shaped perforations have been installed at the drains of baths and washrooms to prevent dust from flowing into the water pipes. If this is not enough, wire mesh or net may be attached to cover the top of the perforated plate.

[0003]

[Problems to be solved by the device]

 In the case of only the eye plate, dust such as hair in the bath may flow into the water pipe or collect in the eye plate and cause clogging. Also, dust removal in this case is very troublesome.

When a wire net or net is attached, the amount of hair flowing into the water distribution pipe is reduced in the above example, and the hair does not collect on the eye plate, but dust removal attached to the wire net or net is as troublesome as described above. However, if you pay attention to the fact that this wire net or net can be removed from the eye dish, it can be made disposable and the need for dust removal can be eliminated. Therefore, the Japanese Patent Application No. 5-3599 previously proposed a dust removal sheet as shown in Fig. 7.

The dust removing sheet is one in which an adhesive 73 is applied to a thin non-woven fabric sheet 71 having a plurality of holes 72 formed on its surface, and the adhesive 73 is attached to a perforated plate. Although this sheet has a simple structure in which the unit price is reduced in consideration of being disposable, it is preferable to further reduce the cost in order to sell and spread the sheet. Therefore, we decided to study the structure of a dust removal sheet that can be manufactured more easily and keep the unit price down.

[0006]

As a result, a reinforcing material 4 is attached to the periphery of a sheet 1 of a non-woven fabric or a net-shaped material cut into a predetermined shape to cover a drainage port, and an adhesive layer is formed on the surface of the reinforcing material. We have devised a drainage sheet for drainage. The adhesive layer of this sheet may be formed by a rewetting adhesive or an adhesive with release paper attached.

As the non-woven fabric forming the sheet, a dry non-woven fabric of ultrafine fibers, particularly a non-woven fabric made of polyester or needle punch, which is preferably cellulosic or polypropylene type. Nonwoven fabrics with a basis weight of about 10 to ²⁰⁰ g / m ² can be used. As the net material, a polyolefin-based flat yarn or split yarn mesh fabric is preferable.

As the re-wetting adhesive constituting the adhesive layer, a water-soluble or water-swellable polymer adhesive is preferable, and for example, a polyacrylic or polyvinyl alcohol-based adhesive can be used. On the other hand, the pressure-sensitive adhesive to which the release paper is attached may be an ordinary polymer adhesive, for example, a butyl rubber-based adhesive or a polyvinyl acetate-based adhesive can be used.

[0009]

[Action]

 Unlike the Japanese Patent Application No. 5-3599, which is a prior application, the dust removing sheet of the present invention is a non-woven fabric or a net that has both water resistance, water permeability and dust blocking property, instead of stopping the holes on the surface of the sheet 1. By processing the sheet material into the sheet 1 having a predetermined shape, the same performance is maintained and the number of manufacturing steps is reduced.

The reinforcing member 4 enhances the strength of the sheet 1 formed of the non-woven fabric or the net-shaped material having the above-mentioned performance. By providing the reinforcing material 4 on the periphery of the sheet 1, the deformation of the entire sheet 1 is prevented and the sheet 1 is easily attached.

【Example】

 Hereinafter, an embodiment of a drainage sheet for drainage according to the present invention will be described with reference to the drawings. FIG. 1 is a partially cutaway perspective view showing a state where the sheet of the first embodiment in which the adhesive layer is composed of a rewetting adhesive is covered and attached to the upper surface of a grid-shaped metal plate in a bath or the like. 2 is a vertical cross-sectional view of the main part of the periphery of the seat of the embodiment, and FIGS. 3 (a), 3 (b) and 3 (c) are perspective views showing the installation and removal of the seat. Further, FIG. 4 is a partially cutaway perspective view showing a state in which the sheet of the second embodiment in which an adhesive layer is composed of an adhesive having a release paper attached is attached to the upper surface of a metallic perforated plate, and FIG. FIG. 6 is a vertical cross-sectional view of the main part of the periphery of the seat, and FIGS. 6A, 6B, and 6C are perspective views showing the installation and removal of the seat.

In the first embodiment, as shown in FIG. 1, a sheet 1 is obtained by cutting a non-woven fabric having a basis weight of 40 g / m ² and high air permeability into a circular shape having two ear pieces 5 and a diameter of 15 cm. The ear pieces 5 are formed on the outer periphery of the seat 1 so as to face outward in the same radial direction. Water-resistant paper is attached to the periphery of the sheet 1 at a distance of 1 cm from the outer periphery in a ring shape as the reinforcing material 4, and the rewetting adhesive 2 is applied on the surface of the reinforcing material 4.

In the present embodiment, in order to save the labor for processing, the reinforcing material 4 to which the re-wetting adhesive 2 has been applied in advance is passed over with a predetermined diameter (13 cm in this embodiment), and this reinforcing material is Since the non-woven fabric is stuck to 4 and punched into the shape of the sheet 1 having the ear piece 5, the rewetting adhesive 2 is also applied to the ear piece 5, as shown in FIG.

The sheet 1 is used as shown in FIG. First, (a) the rewetting adhesive 2 is pre-moistened, and the ear piece 5 is gripped and attached so as to cover the eye plate 6. If there is some dampness around the perforated plate, even if the sheet is directly covered with the perforated plate, the adhesive property of the rewetting adhesive will be restored and it can be attached. In this way, (b) confirm that the rewetting adhesive 2 has been used well and that it has been firmly applied before use. When the dust is collected to some extent, (c) the ear piece 5 may be grasped, peeled from the eye plate 6, and discarded.

[Effect of device]

 The drainage sheet for drainage of the present invention exhibits the same performance as the previously proposed Japanese Patent Application No. 5-3599, but simplifies the process by omitting the holes provided on the sheet surface, and is a reinforcement material. By making it possible to use thinner non-woven fabrics, it is possible to supply products at lower cost and in large quantities.

In addition, in particular, when the pressure-sensitive adhesive layer is composed of a rewetting adhesive, not only the step of attaching the release paper can be omitted, but also the labor of removing the release paper during use is omitted, and the sheet can be directly applied to the drainage port. It has the convenience that it can be pasted by simply scraping. Due to such ease of handling and extremely low manufacturing cost, it is possible to use it by exchanging it every day, for example, and it is extremely practicable.
