Biochemical container

Abstract

A biochemical container is provided, which can open a cover member shutting a container member and can release a tightly sealed condition, without a need for displacing the outer edge section of the cover member. In the present invention, an opening in an end of a container member 110 is openably and closably shut by a cover member 120. When an assisting-opening member 140 is pressed from the outside in such shut condition, the stress is changed to the opening direction by the changing-direction mechanism 150 to exert over the cover member 120. Consequently, the tightly sealed condition of the cover member 120 that shuts the container member 110 can be released.

Description

TECHNICAL FIELD[0001]The present invention relates to a biochemical container utilized for storage of biochemical substances, and particularly relates to a biochemical container, which is configured to openably and closably shut an opening in one end of a container member with a cover member.BACKGROUND ART[0002]Biochemical containers are utilized for storages of biochemical substances in the fields of biochemical experiments and the like. Such biochemical container composed of, for example, a vertically long cylindrical container member having an opening in upper end, and a disk-shaped cover member, which openably and closably shuts the opening of the container member.[0003]Typical biochemical containers are designed to have a size, which allows being held in one hand. For example, such a biochemical container is formed to the structure that the container member and the cover member are connected with a screw structures. However, it is difficult in such type of the biochemical conta...

AI Technical Summary

Benefits of technology

[0020]In the biochemical container of the present invention, when the assisting-opening member is pressed from the outside in the condition that the opening in one end of the container member is openably and closably shut with the cover member, the stress is changed into a stress towards the opening direction by the changing-direction mechanism to exert over the cover member. Consequently, the tightly sealed condition of the cover member that provides the shut condition of the container member can be released. Therefore, it is not necessary to cause a displacement of an edge of the cover member toward the upper direction directly with the fingers, for the purpose of opening the cover member that provides the shut condition of the container member. Consequently, a pollution of the fingers with a biochemical substance stored in the container member, a pollution of a biochemical substance stored in the container member with droplets from the finger surfaces in the operation for opening the cover member, and the like, can be prevented.

Problems solved by technology

However, it is difficult in such type of the biochemical containers to open and close the cover member while holding the container member in one hand operation.

Consequently, it is not easy to open up the cover member in the shut condition from the container member only in one hand operation.

In such occasion, biochemical substances may be splashed from the container member to pollute the fingers, and in turn, it is concerned that the polluted fingers may possibly pollute the biochemical containers and the biochemical substances.

Further, even in the condition that the finger is not polluted, when the container member is held in one hand and the cover member is opened in the other hand, or when the circumference section of the cover member is displaced in upward direction with the thumb to be opened as described above, stains on the surfaces of the fingers drop in the container when the finger passes upward of the opened container, and such droplet may cause contaminations in the biochemical substance in the container.

Consequently, it is difficult to open the cover member only with an elastic force of the hinge mechanism as described above.

In this case, the hinge mechanism must have a dedicated flat spring or the like, requiring complicated structure.

Further, since the cover member rapidly opens when the tightly sealed condition is released, the probability will increase that the biochemical substance be splashed to pollute the fingers and the peripheries.
