Description

  The present invention relates to a disposable toilet seat sheet. More specifically, the present invention relates to a disposable toilet seat sheet used for a public toilet such as a park or a station square.

BACKGROUND ART Conventionally, paper products are known as disposable toilet seat sheets used for public toilets in parks and station squares (see Patent Document 1). These are used in a rolled form like toilet paper. At the time of use, the leading edge of the sheet is pulled with a finger and cut along the cut line. By disposing the disposable toilet seat sheet on the toilet seat, the thigh skin of the seated person does not directly touch the toilet, and the painful cold sensation can be reduced.
After using the toilet seat, the disposable toilet seat sheet is removed from the toilet seat and discarded. At this time, if the sheet is water-soluble, it can be flushed at the time of washing (see Patent Document 2).

However, since the disposable toilet seat sheet of Patent Document 1 is made of paper, the thickness is small, and heat is immediately transmitted to the toilet seat, that is, body heat is immediately absorbed by the toilet seat via the skin of the thigh, and the user feels cold.
Examples of a material that can reduce the coldness include a woven fabric, a nonwoven fabric, and a foamed resin (see Patent Document 3).

  However, disposable toilet seat sheets made of cloth such as woven cloth and nonwoven cloth are not appropriate from the viewpoint of labor and resource saving during production. Further, in order to eliminate the cold sensation, it is necessary to have a thickness that does not hinder the use and carrying of the device. In the case of a non-woven fabric, the adhesive force between fibers becomes weak in water, and is suitable for washing with water (see Patent Document 4).

As the foamed resin, foamed polypropylene, foamed polyethylene, and foamed polyolefin are mainly known (see Patent Document 5). These are excellent materials from the viewpoint of heat because they have excellent heat insulating properties due to the inclusion of air bubbles, and do not easily feel cold when seated. However, disposable like the above is not preferable from the viewpoint of resource saving.
From the viewpoint of resource saving, resin sheets such as polyethylene are excellent. This is because recycling is possible. It is known as a material that is selected in parallel with paper (see Patent Document 6).

However, a resin sheet such as polyethylene is excellent in recyclability and can be easily disposable, but since it is as thin as a paper sheet, heat penetrates immediately, and body temperature is absorbed through the skin. I feel cold.
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a disposable toilet seat sheet that is not only resource-saving but also has excellent bodily sensation from the viewpoint of not feeling cold.

The present inventor has conducted intensive studies on such problems, and as a result, it has been found that by using a bubble cushioning material called so-called bubble wrap, it is possible to achieve bodily sensation that does not make the skin feel cold and resource saving. As a result, the present invention has been completed.
The disposable toilet seat sheet of the present invention is formed using a bubble cushioning material in which bubbles are interposed between one resin sheet and the other resin sheet adjacent to each other. The bubble cushioning material is preferably made of polyethylene. Alternatively, the bubble cushioning material is preferably biodegradable. Alternatively, the bubble cushioning material is preferably water-soluble.

  The disposable toilet seat sheet of the present invention is excellent not only in resource saving but also in bodily sensation from the viewpoint of not feeling cold.

Drawing 1 is an explanatory view showing one embodiment of a disposable toilet seat sheet of the present invention. FIG. 2 is an explanatory view schematically showing a cross section of a bubble portion formed in a bubble cushioning material of the disposable toilet seat sheet of FIG. FIG. 3 is an explanatory diagram showing a modified example of the bubble portion of FIG.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.

Drawing 1 is an explanatory view showing one embodiment of a disposable toilet seat sheet of the present invention. The disposable toilet seat sheet 1 of the present embodiment has a cutout line S1 in a bubble cushioning material 2. The bubble cushioning material 2 is made of polyethylene, and is widely used because it wraps cracks and electronic components or is sealed in a can containing confectionery such as cookies. The bubble cushioning material 2 is called a bubble wrap, has a function of an air cushion, and is sold in stores as a packing material.
A cutout line S2 is formed in the bubble cushioning material 2 in the transverse direction of the seat to separate the pair of toilet seat portions 2a. The cut lines S1 are formed at regular intervals in the sheet longitudinal direction.

  In the figure, the bubble portions 3 with bubbles interposed are arranged. These bubbles 3 are displaced in the longitudinal direction every row. More specifically, the bubble portions 3 in the n-th row (n is an integer) and the (n + 2) -th row have the same longitudinal position. Then, assuming that an arbitrary position in the n-th column is the m-th row, the bubble portion 3 in the (n + 1) -th column is disposed at an intermediate position between the m-th row and the (m + 1) -th row. .

The cut line S1 forms a curved shape line along the toilet seat. This shape line is a dotted line, and the cut portions that have been cut and the connection portions that have not been cut are alternately continuous. Since polyethylene is easily stretched and difficult to cut, the length of the cut portion is longer than that of the connection portion.
A double-sided tape is stuck to an appropriate place on the back side of the toilet seat portion 2a so that it can be temporarily fixed to the toilet seat. As the double-sided tape, 3M Scotch (registered trademark) using an acrylic adhesive that can be easily peeled off can be used.

  FIG. 2 schematically shows a cross section of a bubble portion 3 formed in the bubble cushioning material 2. Although the figure has a substantially rectangular cross section, the shape may be an arc, and the shape is not particularly limited. In such a bubble portion 3, since the material forming the bubble is a resin sheet, the heat conductivity is lower than that of a metal such as copper or iron, and heat is not easily transferred. Further, since the sheet is thin, the cross-sectional area of the heat conduction surface is small, and heat is difficult to move. Further, since the bubble portion is air and functions as an excellent heat insulating material, heat transfer is small. Therefore, since the heat insulation from the skin to the toilet seat is very high, it is difficult for the skin to feel cold when sitting.

  In particular, when the disposable toilet seat sheet 1 shown in FIG. 1 is cooled compared to the body temperature due to the atmospheric temperature in winter when seated, the resin sheet is thin and has low thermal conductivity, so that the temperature of the contact portion with the skin rises immediately. You do not have to feel the coldness of your skin. When the thermal conductivity is small, the temperature in the vicinity of the skin has a larger temperature rise than when the thermal conductivity is large. Conversely, at a point distant from the contact portion with the skin to some extent, the smaller the thermal conductivity, the larger the temperature rise. When the distance from the contact portion is taken on the horizontal axis and the temperature is taken on the vertical axis, the graph becomes a monotonically decreasing graph, and an intersection occurs between the graphs of two materials having different thermal conductivity.

  As raw materials of recycled products, for example, polystyrene (PS), polyethylene (PE) and polypropylene (PP) are to be collected. Since the bubble cushioning material 2 of this embodiment is made of polyethylene, it can be recycled and collected after use, which leads to resource saving.

  Next, a method for manufacturing the bubble cushioning material 2 will be described. First, a cylindrical resin sheet is folded into two layers. Next, after preheating is applied to the two-layered sheet, one resin sheet 4A is adsorbed by the concave adsorbing portion, so that air bubbles are interposed between the adjacent one resin sheet 4A and the other resin sheet 4B. Let it. Next, the two layers are heat-sealed.

Next, a method of using the disposable toilet seat 1 of the present embodiment will be described. The disposable toilet seat sheet 1 is rolled and commercialized like toilet paper. Then, the tip of the bubble cushioning material 2 is pulled by a predetermined length, and in a state where the pair of toilet seat sheets 2a are taken out, the bubble cushioning material 2 is cut along a cut line S2 along the transverse direction of the sheet. Cut off the sheet.
A plurality of sheets may be bundled and commercialized.

  Next, one of the pair of toilet seat portions 2a formed in the separated seat is separated from the seat. After peeling off the release paper of the double-sided tape on the back side of the separated toilet seat portion 2a, one toilet seat portion 2a is temporarily fixed to the toilet seat. Next, the other toilet seat portion 2a is also separated from the sheet, the release paper is peeled off, and the seat is temporarily fixed to the toilet seat.

  In the disposable toilet seat sheet of the above-described embodiment, the bubble cushioning material 2 in which bubbles are interposed between the one resin sheet 4A and the other resin sheet 4B adjacent to each other is used. Resource saving can be achieved as compared with a case where a cloth is used or a case where a foamed resin is used. In addition, it has excellent bodily sensation from the viewpoint of not feeling cold. Here, since the bubble cushioning material 2 is made of polyethylene, it is a recyclable material, which can contribute to resource saving.

Although the present invention has been described above, the present invention is not limited only to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the essence of the present invention.
In the above-described embodiment, an example was described in which a material having recyclability was used as the bubble cushioning material 2 of the disposable toilet seat sheet 1, but the present invention is not limited to this. For example, a biodegradable material may be used. If a biodegradable material is used, no harmful gas such as dioxin is generated at the time of incineration, so that it can be discarded as ordinary waste.

  Further, for example, a water-soluble material may be used. With a water-soluble material, the disposable toilet seat sheet can be peeled off from the toilet seat after use of the toilet seat, discarded in the toilet bowl, and washed with water as it is. As a water-soluble material, a material containing polyvinyl alcohol (PVA) as a main component is known, and specifically, a water-soluble film called Solvac (registered trademark) sold by Aicello is known.

  Further, in the above-described embodiment, the bubble cushioning material 2 composed of two layers has been described. However, as shown in FIG. Is also good.

  INDUSTRIAL APPLICATION This invention can be utilized for a disposable toilet seat sheet. For example, it can be used for a disposable toilet seat sheet used for a public toilet such as a park or a station square.
