Description

[Detailed description of the invention] This invention relates to a container for storing samples such as blood used in the field of clinical testing.

Conventionally, containers made of glass have generally been used to store samples such as blood, but they are often used repeatedly because they are expensive.

In recent years, sample containers made of synthetic resin have become available at low cost, making them disposable and eliminating the need for cleaning, but containers made of synthetic resin are lighter than those made of glass. Therefore, there was a drawback that it was easy to accidentally fall over and spill samples such as blood.

In addition, both glass and conventional synthetic resin containers have the problem that when the lid is opened and closed, the sample adhering to the lid tends to leak out onto the outer wall of the container and adhere to hands.

The purpose of this invention is to solve these problems,
To provide a sample container with a structure that prevents samples from being accidentally spilled or attached to hands.

The details of this invention will be explained below based on the drawings showing one embodiment of this invention.

The sample container according to this invention includes a bottomed main body 2 made of a synthetic resin material such as polyethylene, which stores a sample 1 such as blood, and
For example, it is composed of a lid body 3 made of a material such as polypropylene.

The main body 2 is a cylindrical container, and has an opening 4 having a diameter of at least half the outer diameter or less, and a recess 5 around the opening.
is the condition.

The lid body 3 is provided with a protrusion 6 that fits into the opening 4 of the main body 2, the tip of the protrusion 3 is located above the lower edge 8 of the outer peripheral edge 7, and the tip of the protrusion 3 has a smooth spherical surface. It exhibits the following.

The bottom part 9 of the main body 2 is smooth and slightly curved upward, and there is a slight gap between the outer wall 10 of the main body 2 and the inside of the outer peripheral edge 7 of the lid 3, so that the recess 5 and the outside are separated. Allows ventilation between the

The sample 1, such as blood, stored in the main body 2 is prevented from evaporating or being contaminated by dust due to the fitting contact between the protrusion 6 and the opening 4 of the main body 2.

Furthermore, even if the sample attached to the protrusion 6 leaks out little by little toward the depression 5 as the lid body 3 is opened and closed, it will accumulate in the depression 5.
Since it does not flow toward the outer wall 10 of the main body 1, it does not get your hands dirty.

The sample collected in the depression dries naturally as there is ventilation with the outside.

Furthermore, even if the lid 3 is removed and placed on a desk or the like, the protrusions 6 will not come into direct contact with the surface, and since the protrusions 6 are rounded, the adhered sample will spread evenly, resulting in droplets. It won't fall and make a mess on your desk.

Furthermore, the lid 3 is opened and closed by holding the outer periphery 7 with fingers, and since the protrusion 6 is located inside the outer periphery, direct contact with the sample can be prevented.

The sample such as blood stored in the container main body 2 is usually about several ml, and the old main body 2 has a volume of 10 to 2 ml, which is 5 to 10 times the sample.
Those with an internal volume of about 0m1 are easy to handle.

On the other hand, the opening 4 is approximately half the outer diameter of the main body 2, and even if the sample 1 is accidentally turned over, the liquid level of the sample 1 will not become higher than the opening 4 and will not flow out.

The recess in the bottom 9 of the main body 2 is for the container to stand stably upright.

As described above, the container of the present invention has a molded synthetic resin door and can be supplied at low cost, so it can be used as a disposable container, and even if the container is rolled over with the lid removed, the sample will not leak out. Or, you won't get your hands dirty with the sample that leaks out little by little as you open and close the lid, or you won't touch the fitting part of the lid where the sample is most likely to stick, making it difficult for the sample to stick to your hands. has an effect,
It is very effective to use it in hospital laboratories, etc., which handle large quantities of pathological specimens.
