Description

DETAILED DESCRIPTION OF THE INVENTION Originally, as shown in FIG. 5, a sealed plastic container with a dust-free and sterile interior in which a cap body 1' is connected to a container body 2' via a thin wall part 3' was used. It has just been attempted.

Then, at a pharmaceutical company or the like, the cap body 1' is separated from the container body 2 at the thin wall part by breaking it off or twisting it off (separation point is B-B
Medicines and the like were put into the container body 2' through the opening 4' created by this separation, and the cap σ was inserted into the opening as shown in FIG.

In this way, since the separation point is the opening edge of the container body, the fluff-like plastic particles that inevitably occur at the separation point will be removed when the cap body is separated or when the cap C' is inserted. At times, the cap or fingers may come into contact with the cap and peel it off, resulting in the inconvenience that it falls into the drug inside the container body.

Needless to say, the operation of removing the cap body, which is performed to seal the medicine in the dust-free and sterile container body, must be carried out extremely quickly in order to prevent bacteria from the outside air from entering the container body.

Since this work is performed during a series of assembly operations, there is a strong demand for it to be completed quickly in order to improve efficiency.

Although the above-mentioned method can meet this requirement for rapid separation, it cannot avoid the fatal defect of drug contamination by fluff-like particles mentioned above.

Although not shown, an opening is provided in a separate fitting that is inserted and fixed into the container body, and the lower end of the cap is screwed deeply into the outer periphery of the protruding opening of the fitting.
It is also known that the container is integrally connected to the container body through a thin wall.

In this case, the thin part that connects the cap body and the container body is located far away from the inner edge of the opening of the opening in the mounting body that follows the container body, so the fluffy part that is generated when the cap body is removed is Although there is no risk of pieces entering the container body,
To remove the separated cap, it must be unscrewed via a long thread.

Therefore, the separation of the cap body is not completed smoothly.

That is, as time passes for unscrewing the container, bacteria in the outside air may enter the container along the threaded portion.

Not only this, but it is not desirable in terms of work efficiency that it takes time to open the opening.

In addition, the number of parts is large, making manufacturing cumbersome.

The present invention has been made in consideration of the above points.
The embodiment shown in FIG. 4 will be described.

In the present invention, the cap body 1 and the opening 4 of the container body are integrally formed, and the cap body is attached to the container body 2 via a thin wall 3 at a location on the outside of the opening 4 at a distance R from the inner edge 5. The inside of the connected parts is covered with a dust-free and sterile plastic sealed container.

Since the present invention is as described above, when the cap body is separated from the container body by breaking off or twisting it off, this separation point is far away from the inner edge of the opening. It is safe because there is no fear that fluff-like particles generated at the separation part will enter the container body.

Moreover, the inner edge of the opening is immediately exposed when separated.

Therefore, it is possible to prevent bacteria from the outside air from entering the container.

Naturally, it greatly contributes to improving work efficiency.

It is clear that the number of parts is small and manufacturing is easy.

In Fig. 1, the thin-walled connection point between the cap and the container body is at the outer edge of the opening, separated by a gap R from the inner edge of the opening, and in Fig. 3, it is located outside the protruding opening. Further, there is a large gap R following the upper end of the opening, and a part of the cap body is vertically disposed across this gap, and its lower end is connected to the container body 2 via the thin wall 3.
