2. Description of the Related Art A fecal occult blood test is widely used for screening for colorectal cancer and rectal cancer, but in general, a stool collected at home is used as a sample for testing in a hospital. In qualitative analysis using latex, the designated stool collection stick is used because there is a restriction on the amount of stool preparation when preparing a sample, but even if a stool collection stick is used, an accurate amount of stool is collected. This is difficult, and in the past, after collecting stool, excess stool was removed by wiping the stool stick with paper or the like.

However, since the stool is dirty and has a strong odor, the stool may accidentally adhere to a hand when wiped with paper or the like, and the cap of the stool collection container may be opened to make a stool collection stick. Since the sample was taken, the creator of the sample often suffered from a bad odor, which was a problem. In addition, with the conventional stool collection container containing the solution, especially for some subjects such as elderly people, even if the lid was intended to be closed after stool collection, it could not be completely closed and leakage occurred during transportation. May occur.

Therefore, as a means for solving the above problems, a stool collection container disclosed in Japanese Utility Model Laid-Open No. 2-140468 has been proposed. This stool collection container is an elongated container body having a drip at the tip sealed with a lid with a stick, and a rubber stopper having a stick insertion hole is fixed inside the container body, and the space between the lid and the container body is fixed. It is characterized by sealing the O-ring with a malt and a filter inside the drip part, so that the stick can be inserted into the insertion hole of the rubber stopper to wipe off excess stool attached to the stick. ing. However, this stool collection container also has a high cost because it has to be fixed in the container body, which increases the cost of the stool collection container. It is necessary to pierce the sealing part of the dripping part with a perforator when dripping liquid), which may be time-consuming and dirty, and it is necessary to wash the perforator each time. It has drawbacks.

[0005]

The present invention has been made in view of the above circumstances and has a lower cost than the conventional one.
It is an object of the present invention to provide a stool collection container in which the dropping portion of the suspension can be opened by a simple operation of twisting it without any labor for production, and which has good reproducibility of the inspection.

[0006]

In order to solve the above-mentioned problems, the present invention provides a cylindrical container having a closed end and an open end for containing a dissolution liquid, the closed end of which is a container. A small diameter drip part with a closed tip is provided on the
A container main body in which a filter is provided in the drip section adjacent to the closed end, and an easily breakable fragile section is provided on the tip side of the container main body; A member for closing the open end in a liquid-tight manner, comprising a plug member made of a soft synthetic resin in which an insertion hole closed by a closing film is formed in the axial direction, and a member capped on the plug member. Therefore, a stool collection container having a configuration including a cap member having a stool collection stick that can be closely inserted into the inner wall of the insertion hole of the plug member is adopted.

[0007]

According to the above construction, when the stool collection stick of the cap member is inserted into the insertion hole of the stopper member, the excess stool attached to the stool collection stick is inserted into the insertion hole (particularly the part of the closure membrane).
Since it is wiped off with, a fixed amount of stool sample is collected in the solution of the container body. In addition, when the suspension is dropped onto the test device, it can be opened by a simple operation of twisting the tip of the dropping portion.
