Description

Technical Field

[0001] The present invention relates to a toilet bowl for treating human excrement, and particularly to a toilet seat that can be used to prevent excrement from adhering to or splashing on the inner wall surface of the toilet bowl.

Background Art

[0002] Generally, when using the toilet for excretion, excrement may adhere to the inside of the toilet bowl. This occurs when the inner wall of the toilet bowl is dry. Also, this can happen when the toilet bowl is made of a material such as porcelain and has partially rough inner wall surfaces. Excrement stains on the inner wall of the toilet bowl are difficult to remove when dried, so detergents or coating agents for preventing dirt adhesion are sold for the inner wall of the toilet bowl, but they are expensive. Moreover, they are the cause of bad odors and are unsanitary.

[0003] Similarly, when using the toilet for excretion, splashing may occur when the area of the water accumulation part inside a Western-style toilet bowl is large. This is what is commonly called "change," which is very unpleasant and unsanitary. In Western-style toilet bowls, it seems that the amount and area of the water accumulation can be adjusted depending on the type of toilet bowl size or the structure of the toilet drainage facility, but such adjustment is difficult for the layperson. Also, when the area of the water accumulation inside the toilet bowl is small, the adhesion of excrement described above may increase, and it is quite a difficult problem to improve both simultaneously.

[0004] To solve such problems, various proposals and technologies have been utilized to date. These include the development and commercialization of dedicated coating agents for coating the inner wall of the toilet bowl to avoid excrement adhesion, lubricants, detergents and deodorants containing them, and general consumer materials for toilet cleaning such as sanitary appliances. However, these are relatively expensive and not economically inexpensive. Also, they have no effect on splashing caused by excrement.

[0005] For example, Patent Document 1 discloses a technical concept for a composition for reducing or preventing water splashing when using a toilet, comprising one or more surfactants in an amount of 1 / 10 to 30% wt / wt, one or more carbon dioxide generating compounds in an amount of 5 to 40% wt / wt, and one or more acids in an amount of 5 to 40% wt / wt.

[0006] However, in this example, the compound drugs are expensive, and it is difficult to completely avoid the above problems with chemical agents alone. In other words, even considering only the economic aspect, this does not offer a fundamental solution. [Prior art documents] [Patent Documents]

[0007] [Patent Document 1] Special Publication No. 2024-543349 [Overview of the project] [Problems that the invention aims to solve]

[0008] Current technologies or technological concepts have not offered fundamental solutions to problems such as excrement adhering to the inner wall of the toilet bowl when defecating, and splashing occurring when the water area inside the Western-style toilet bowl is large. These problems are, firstly, unsanitary and cause foul odors. And above all, they are time-consuming and difficult to clean.

[0009] The challenge and objective of this invention is to develop and provide an inexpensive, hygienic, and easy-to-use method or component that completely prevents excrement from adhering to the inner wall of the toilet bowl and splashing from the water reservoir inside the toilet bowl when using the toilet.

[0010] In short, the present invention aims to solve these problems of the prior art, and its objective is to provide a toilet seat that is easy to handle, hygienic, inexpensive, and economically efficient. [Means for solving the problem]

[0011] (Claim 1) To solve these problems, the toilet sheet according to the present invention is a water-soluble paper material and has an egg-shaped outer circumference that approximates the shape of the inner surface wall of a Western-style toilet bowl. When using the toilet, it can be spread and laid inside the toilet bowl to prevent splashing and adhesion of excrement to the toilet bowl, and can be flushed down the drainpipe at the same time as the toilet is flushed.

[0012] In other words, since the toilet sheet according to the present invention is made of a water-soluble paper material, it can be wet and dissolved simultaneously with toilet flushing and washed down the drain. Furthermore, since the shape of the toilet sheet according to the present invention is an egg-shaped outer circumference that approximates the shape that covers the inner surface wall of a Western-style toilet bowl, it can be spread out and laid along the inner wall of the roughly egg-shaped toilet bowl when using the toilet. This water-soluble paper material begins to dissolve when it comes into contact with a puddle of water, but it can maintain its shape for the short time it takes to use the toilet.

[0013] Therefore, the toilet sheet according to the present invention can be spread and laid inside the toilet bowl when using the toilet to prevent splashing and adhesion of excrement to the toilet bowl, and can also be flushed down the drainpipe at the same time as the toilet is flushed.

[0014] Furthermore, the toilet sheet according to the present invention is also useful for stool collection in colorectal cancer screening. In addition, in cases of certain illnesses, it may be necessary to regularly observe or collect stool samples. In such cases, the toilet sheet according to the present invention is extremely effective.

[0015] (Claim 2) Furthermore, the water-soluble paper material of the toilet seat according to the present invention may be a multilayer paper consisting of one, two, or three or more layers of water-soluble paper material, and each layer or all layers may be impregnated with a cleaning agent, coating agent, deodorizer, or fragrance.

[0016] If the paper material used for toilet seat covers is impregnated with a cleaning agent, coating agent, deodorizer, or fragrance, it will become more comfortable.

[0017] (Claim 3) The water-soluble paper material of the toilet seat according to the present invention has an egg-shaped outer circumference that approximates the shape of the inner surface wall of a Western-style toilet bowl, and may also have a rectangular gusset portion with a width of 3 cm to 6 cm on the side facing the person's back when defecating.

[0018] Having a gusset on one side of the toilet seat improves its ease of handling.

[0019] (Claim 4) The water-soluble paper material of the toilet seat according to the present invention has an egg-shaped outer circumference connected to the inside of a rectangular paper material with a cut-out allowance. Therefore, it can be used in a form where the egg-shaped portion can be cut off when defecating.

[0020] The trimmed-off parts can be placed on the toilet seat, making it very hygienic to sit on.

[0021] As a result, the toilet seat according to the present invention can be easily manufactured, packaged as a product, and easily removed when in use.

[0022] (Claim 5) The water-soluble paper member of the toilet seat according to the present invention has an oval outer peripheral shape approximated to a shape that covers the inner surface wall of a Western-style toilet bowl, and the surface is folded in a plurality of stepped pleated shapes in the vertical direction or the horizontal direction. When used for excretion, it can also be laid in the toilet bowl with the pleated shape spread out.

[0023] Thereby, the water-soluble paper member of the toilet seat according to the present invention can maintain its shape sufficiently during the excretion time without being easily dissolved by the water in the toilet bowl when used for defecation, and can achieve its original purpose. Also, since it is folded in a pleated shape, there is an advantage that the container packaging form can be made small.

[0024] (Claim 6) In addition, the water-soluble paper member of the toilet seat according to the present invention has an oval outer peripheral shape approximated to a shape that covers the inner surface wall of a Western-style toilet bowl. When spread out, it becomes a bag shape. The outer periphery of the bag shape spreads over the upper side of the inner wall of the toilet bowl, and the inside of the bag shape is laid on the lower side inside the toilet bowl. Moreover, the outer periphery of the bag shape has a plurality of protruding fold portions, and the protruding fold portions protrude beyond the outer periphery of the upper surface of the toilet bowl and can be applied to and sandwiched by the toilet contact foot portions on the back of the toilet seat for use.

[0025] That is, if the toilet seat according to the present invention is in a bag shape that spreads in the toilet bowl, it can more effectively prevent the splashing of excrement and its adhesion to the toilet bowl. Also, by having a plurality of protruding fold portions on the outer periphery of the bag shape, the protruding fold portions can be applied to and sandwiched by the toilet contact foot portions on the outer periphery of the upper surface of the toilet bowl on the back of the toilet seat for use. The toilet seat according to the present invention does not shift during the use for excretion.

[0026] (Claim 7) Furthermore, the water-soluble paper member of the toilet seat according to the present invention has a structure formed like a paper balloon. When used for excretion, it can also be inflated by enclosing exhaled air inside the paper balloon and used by placing it in the toilet bowl.

[0027] The water-soluble paper material of the toilet seat according to the present invention is processed into a balloon-like shape and folded. By sealing in exhaled air through the exhalation seal opening, it inflates into a spherical shape, and in that state it can be placed in the water reservoir inside the toilet bowl or inside the toilet bowl. When defecating or using the toilet, the spherical paper material begins to dissolve and spreads to cover the inside of the toilet bowl. In other words, because it is in the shape of a paper balloon, it can be easily inflated and placed inside the toilet bowl, solving the problem of the present invention. Furthermore, because it is in the shape of a paper balloon, if patterns or anime characters are printed on it, infants and children can use the toilet seat according to the present invention in a way that is enjoyable and doesn't feel out of place.

[0028] While the toilet seat according to the present invention can take the forms described above, it can also take various other similar forms. However, since these similar forms are similar in spirit and method to the present invention, we assert that they are part of the present invention and are included within it. [Effects of the Invention]

[0029] According to the present invention, it is possible to completely prevent excrement from adhering to the inner wall of the toilet bowl and splashing back from the water reservoir inside the toilet bowl when using the toilet, and to develop and provide an inexpensive, hygienic method or component that anyone can easily use.

[0030] Furthermore, according to the present invention, it is possible to provide a toilet seat that is easy to handle, hygienic, inexpensive, and economically advantageous. [Brief explanation of the drawing]

The unnecessary portion 5 can be placed on the toilet seat and sat on, making it hygienic.

[0038] Figure 4 is a conceptual diagram showing the bag-shaped toilet seat according to one embodiment of the present invention. As shown in the figure, the toilet seat according to one embodiment of the present invention is bag-shaped 7. When using it, spread it out inside the toilet bowl, of course with the bottom of the bag-shaped seat facing the bottom of the toilet bowl.

[0039] As shown in Figure 4, the toilet seat according to one embodiment of the present invention has a plurality of protruding pleats 8 on the bag-shaped opening side, and is laid with the pleats 8 placed around the top surface of the toilet bowl. The underside of the toilet seat has about four or more feet that come into contact with the top surface of the toilet bowl, and the pleats 8 are sandwiched between the top surface of the toilet bowl and the feet of the toilet seat, so that the bag-shaped toilet seat according to one embodiment of the present invention can be set up stably and can be in a convenient shape when defecating.

[0040] The above illustrates and describes several examples of toilet seat configurations according to one embodiment of the present invention.

[0041] It should be noted that the present invention is not limited to the embodiments described above, and can be implemented with various modifications without departing from the spirit of the invention. However, it is asserted that all of these are part of the technical concept. [Industrial applicability]

[0042] As described above, the present invention makes it possible to completely prevent excrement from adhering to the inner wall of the toilet bowl and splashing back from the water reservoir inside the toilet bowl when using the toilet, and to develop and provide an inexpensive, hygienic method or component that anyone can easily use.

[0043] Furthermore, according to the present invention, a toilet seat can be realized that is inexpensive and economically efficient, while significantly improving productivity and workability.
