TECHNICAL FIELD

The present invention relates to a water-soluble or water-decomposable feces sampling tool which does not cause jamming of a drainage pipe even when flushed into a flush toilet.

BACKGROUND ART

Conventionally, a feces sampling tool disclosed in Patent Document 1 are known.

FIG. 9is a perspective view drawing showing a conventional sampling unit91, andFIG. 10is a drawing showing a usage mode of the tool91.

As shown in a usage drawing ofFIG. 10, both ends of the stool91are affixed to the left and right surfaces of an upper edge of a rim portion921of a toilet stool92.

FIG. 10(A) is a plan view.FIG. 10(B) is a cross-sectional view taken along the line X1-X1(front view) inFIG. 10(A).FIG. 10(C) is a cross-sectional view (side view) taken along line X2-X2inFIG. 10(A).

As shown inFIG. 9, the feces sampling tool91comprises a paper cup body911and paper band portions912a,912bextending in left-right direction.

The cup body911and the band portions912a,912bare integrally formed by pressing a plurality of sheets of paper.

An adhesive layers913aand913bare formed on the lower surface of each edge of the band portions912aand912b(the end portion on the side opposite to the cup body911).

The band portions912a,912bare attached to left and right of the upper edge of the rim portion921of the toilet stool92.

Although not shown, the band portions912a,912bcan also be attached to the left and right of the upper edge of the toilet seat922of the toilet stool92.

In the stool sampling by the feces sampling tool91shown inFIG. 9, the stools are sampled by the cup body911, so that it is possible to prevent the sampling error occurring when stools are hard.

The feces sampling tool91must have strength such that the cup body911and the band portions912a,912bare not broken due to the weight of a stool at the time of taking a stool.

Therefore, in the feces sampling tool91, for increasing the strength of the cup body911, the thickness of the paper constituting the feces sampling tool91is made thicker, or the number of laminated sheets of paper is increased.

On the other hand, it is necessary for the feces sampling tool91to be able to flush the whole (the cup body911, the band portions912a,912b) after the bowel movement. For this reason, the feces sampling tool91must be either immediate-water-soluble or immediate-water-disintegratable.

DISCLOSURE OF THE INVENTION

Problem to be Solved by the Invention

However, if the thickness of the paper is increased or the number of laminated sheets is increased in the feces sampling tool91, immediate water-soluble or hydrolysis is not performed, and therefore a problem arises that the paper jam occurs in the drain pipe.

Particularly, in Asian countries other than Japan, the drainage pipe diameter is often small, so paper jamming is more likely to occur.

The object of the present invention is to provide a water-soluble or water-decomposable (also referred to as “water-soluble/water-decomposable”) sampling device.

Means to Solve the Problem

The present invention is summarized as follows.

[1]

A feces sampling tool comprising a central rectangular area and two side rectangular areas symmetrically formed on left and right of the central rectangular region,wherein, a sampling portion is formed in the central rectangular area,a band portion is formed in each of the two side rectangular areas,the sampling portion and the band portions are made of one or a plurality of water-soluble or water-disintegratable paper,each part of the band portions is stuck on left and right upper surfaces of a toilet seat or left and right upper surfaces of a rim portion, whereby the sampling portion is suspended in a toilet stool,a weight per unit area of the side rectangular area is ⅘ or less of a weight per unit area of the central rectangular area.

[2]

A feces sampling tool comprising a sampling portion and two band portions symmetrically formed on left and right sides of the sampling portion,wherein the sampling portion and the band portions are made of one or a plurality of water-soluble or water-disintegratable paper,each part of the band portions is stuck on the left and right upper surfaces of a toilet seat or left and right upper surfaces of a rim portion, whereby the sampling portion is suspended in a toilet stool,a vertical width of the band portion is formed narrower than the vertical width of the sampling portion.

In the present invention, the term “water-soluble” means a property that when the toilet paper or the like is wetted with water, it is decomposed to lose its strength and decomposes, and the term “water decomposability” means maintaining a constant strength (wet strength) It means a property to break down finely when added.

Effect of the Invention

The feces sampling tool of the present invention does not cause clogging of paper such as a drain pipe even if it is flowed into a flush toilet after use.
