Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an inspection container, and more specifically, as a sterilized container, it is possible to easily set a temporary fastening position and a final fastening position of a cap in a sterilization process. Regarding the container.

(Prior art and its problems) Inspection containers used in hospitals, various research institutes, etc. require cleanliness and sterility of the containers. Therefore, after being subjected to a sterilization process, their sterility is maintained. Have been shipped as.

When sterilizing this container for inspection, in order to sterilize the inside of the container body as well, do not completely tighten the cap, so that there is a slight gap between the top plate inside the cap and the mouth of the container body. It is necessary to temporarily tighten the cap and finally tighten the cap to seal the container after the sterilization is completed.
Conventionally, since the position of this temporary tightening depends on the sense of the operator, there is a problem that variations occur, and the cap falls off from the container body during sterilization or transportation. Furthermore,
The conventional method that relies on the sense of the operator is slow in work and is economically disadvantageous.

Therefore, an object of the present invention is to provide an inspection container in which the cap can be easily and surely set to the temporary tightening position during the sterilization process.

(Means for Solving the Problems) According to the present invention, a container body having a mouth-neck portion having a cylindrical outer peripheral surface and a skirt wall having a cylindrical inner peripheral surface are provided.
A combination with a synthetic resin container lid fitted to the mouth and neck and rotated in a predetermined direction relative to the mouth and neck so as to be attached to the mouth and neck. Has at least one locking projection and at least one recess formed on the inner peripheral surface of the skirt wall for locking the locking projection. In the final stage of the mounting operation of mounting the container lid on the mouth and neck of the container, the temporary tightening position where a gap is formed between the tip of the neck of the container mouth and the inner surface of the top plate of the container lid, and the container mouth The locking projection provided on the container is locked to the recess provided on the inner peripheral surface of the cap at both the final tightening position where the tip of the neck and the inner surface of the top plate of the container come into close contact with each other. A container is provided.

(Example) The present invention will be described with respect to the inspection container 1 shown in Fig. 1 which is an example of the inspection container of the present invention.

In FIG. 2 which is a cross-sectional view showing the locked state of the container mouth 3 of the container 1 and the cap 2 shown in FIG. 1, the locking projections 4a, 4b provided on the container mouth 3 are provided on the cap. Protruding 5
The positions of the caps in the temporarily tightened state and the final tightened state are determined by being locked in the concave portions 7a, 7b formed by a, 6a and 5b, 6b.

In FIG. 3, which is a cross-sectional view of the container mouth 3 and the cap 2 showing the fitted state of the container body and the cap of the container of the present invention, the right half shows the temporarily tightened state of the cap before the sterilization process, and the left side. Half shows the state in which it is fully tightened after the sterilization is completed. In FIG. 3, the locking projection 4a (4b) provided on the container mouth 2 is locked to the recess formed by the projections 5a (5b) and 6a (6b) provided inside the cap 3. Has been done. On the inner surface of the cap top plate portion, when the container body and the cap are in the final tightened state, an inner seal 9 that fits inside the container mouth portion and a seal portion that abuts the tip 8 of the container mouth portion
10 are formed.

In the right half showing the temporarily tightened state, the locking projections 4a (4b) provided at the container mouth are the projections 5a provided inside the cap.
It is locked in the recess formed by (5b) and 6a (6b). At this time, depending on the length of the projections 5a (5b) and 6a (6b) provided inside the cap, only the upper portion of the locking projection 4a (4b) may be locked in the recess. Even in this case, the operator must be sure that the locking projection 4a is
It is possible to obtain a feeling that (4b) is locked in the recess. Of course, both the projections 5a (5b) and 6a (6b) and the locking projections 4a (4b) are long enough that the locking projections are completely housed in the recesses in both temporary tightening and final tightening. However, it is difficult to swivel the cap if it is too long. Therefore, it is necessary to form the projection so that the projection is locked only at the temporary tightening position and the final tightening position.

In this temporarily tightened state, a gap d is provided between the container mouth end 8 and the inner seal portion 9 inside the cap top plate portion. Therefore, when sterilizing the container, the sterilizing gas penetrates into the container through this gap,
The inside of the container can be sufficiently sterilized.

The gap d is determined by the pitch of the screw and the length of the inner seal portion, but the gap d is preferably 0.1 to
It is preferable to set it to 1.5 mm.

The left half showing the fully tightened state is 18
With the cap rotated by 0 °, the locking projections 4a (4b) provided on the container mouth are locked in the recesses formed by the projections 5a (5b) and 6a (6b) provided inside the cap. Has been done. At this time, similarly to the temporarily tightened state, depending on the lengths of the protrusions 5a (5b) and 6a (6b) provided inside the cap, only the lower portion of the locking protrusion 4a (4b) may be locked in the recess.

In this fully tightened state, the container mouth end 8 is the seal part.
The inner seal 9 is in contact with the inner seal 9, and the inner seal 9 is fitted inside the mouth of the container, so that the container is sealed.

Referring to FIG. 4 for explaining the container locking mechanism of the present invention, protrusions 5a (5b) and 6a (6b) are provided inside the cap, thereby forming a recess 7. Fourth
In the figure, the clockwise direction (arrow A) is the direction to open the cap, and the counterclockwise direction (arrow B) is the direction to close the cap.

The slope 5 of the projection 5a (5b) on the concave portion 7 side is formed to be steeper than the slope of the slope 13 on the opposite side and the slopes 14 and 15 of the projection 6a (6b). This is to prevent the cap from freely returning, which ensures the locked state in the temporarily tightened state and the final tightened state. Furthermore, since the other slopes of the protrusions are relatively gentle, the cap can be opened and closed gently, and the impact on the cap can be reduced.

At least one locking mechanism between the cap and the container mouth,
That is, the combination of the concave portion on the inner peripheral surface of the cap and the protrusion on the container mouth may be one or two. In one case, the cap is rotated 360 ° from the temporary tightening position to reach the final tightening position, and in two cases, the cap is rotated 180 ° from the temporary tightening position to reach the final tightening position. Even if the number of projections on the inner surface of the cap is not the same as the number of projections on the container opening, even if there are two recesses on the inner surface of the cap and one projection on the container opening, 180
It is possible to reach the final tightened state by rotating at °.

In the present invention, since the cap is rotated during the manufacturing process, it is preferable to use a multiple thread screw. By using this multi-start screw, the turning of the screw for closing the cap can be reduced and the work efficiency is good.

After manufacturing, the inspection container of the present invention is sealed in a bag partially using a gas permeable member in a temporarily tightened state, sterilized with ethylene oxide gas or the like, and then finally tightened.

(Effect of the Invention) According to the present invention, the projection provided on the container is provided on the inner peripheral surface of the cap at a position where a gap is formed between the tip of the container mouth and the inner surface of the container lid top plate. At the position where the tip of the neck of the container and the inner surface of the top plate of the container come into close contact with each other, the projection provided on the container is again locked to the recess provided on the inner peripheral surface of the cap. This makes it possible to easily and reliably set the cap to the temporary tightening position during the sterilization process.
