Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a highly airtight storage container suitable for storing various reagents, such as prepared standard reagents, volatile reagents, and valuable reagents, which are mainly used in experiments and the like.

[0002]

[Prior art]

 Conventionally, as this type of storage container, a container in which various reagents are inserted into the mouth of the container body so that the shaft portion of the sealing stopper can be freely opened and closed via a screwing means of a female screw portion and a male screw portion, The screw of the sealing plug is screwed into the mouth of the container so as to be openable and closable through the press-fitting means of the cylindrical press-fitting hole and the cylindrical press-fitting. Is screwed openably and closably through sealing means such as rubber packing.

[0003]

[Problems to be solved by the invention]

 However, in the conventional storage container, the shaft of the sealing stopper is screwed openably and closably into the mouth of the container body for storing various reagents only through the screwing means, the press-fitting means, or the sealing means alone. Since the volatilization of the organic solvents of the various reagents contained in the container body cannot be reliably prevented, the concentration of the standard reagents prepared by diluting the organic solvents with various volatile organic solvents can be stored for a long period of time. In addition, the organic solvents of various reagents are easily volatilized, and the concentration scale is not reliable, and the loss of expensive various reagents is large. In addition, the number of times that an artificial difference is caused in the preparation increases, and the amount used once for a gas chromatograph or the like is very small. Necessary and very uneconomical. Furthermore, even when a small amount of various reagents were used, the entire shaft of the sealing stopper was open, so that the organic solvent volatilized violently, which was extremely wasteful.

[0004] Therefore, the problem of the present invention was devised in view of the above-mentioned viewpoints, and it was intended to prevent the volatilization of the organic solvent of various reagents and to make the scale of the concentration reliable. In addition to minimizing the loss of expensive reagents, preparing various reagents in advance in large quantities reduces labor and reduces the number of artificial differences in the preparation, and reduces the economics of large-scale preparation. Another object of the present invention is to provide a highly airtight storage container that can significantly reduce the volatilization effect of organic solvents when using a small amount of various reagents, and can minimize the volatilization of organic solvents.

Into the stopper head of the large hermetic stopper, and insert the shaft of the small hermetic stopper for preventing the evaporation of the organic solvent when a small amount of the various reagents are used, into the injection needle insertion hole of the shaft of the large hermetic stopper. Into the container body through a press-fitting means, a screwing means, and a sealing means so as to be openable and closable, so that the large sealing stopper and the small sealing stopper form a double stopper structure. is there.
