Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cylindrical container for accommodating elongated objects such as rolled drawings and drills for rock drills.

[0002]

2. Description of the Related Art In a conventional cylindrical container for accommodating a slender object of this type, a slender object is housed in a container body and then a lid is fitted on the container body. In addition, a female screw is formed in the opening of the lid, and a female screw is screwed onto the male screw so that the lid does not come out of the container body.

However, in this screw structure,
There is a problem that the stored object may come out because it is easily loosened. As a solution to such a problem, there is one in which a ring-shaped protrusion is formed on the outer surface near the opening end of the container body and a ring-shaped recess is formed on the inner surface near the opening end of the lid. .

In this structure, when the lid is fitted on the container body, the lid is fitted on the container body in such a manner that the recessed ridge of the lid is forcibly pushed into the ridge of the container body. The engagement of the groove prevents the lid from accidentally slipping out of the container body.

[0005]

As described above, since the protrusion of the container body and the recess of the lid are prevented from coming off by the engagement, the outer diameter of the protrusion is compressed and the inner diameter of the opposite surface is enlarged. ,
At the time of fitting or withdrawing, the outer diameter of the ridge must be compressed by the opposite surface, and it is necessary to apply a considerably unreasonable force, and there is a drawback that it is very difficult to fit and remove the lid.

The present invention is intended to solve the above-mentioned problems, and an object of the present invention is to smoothly and unreasonably insert or remove the lid even though there is no risk that the lid will fall out inadvertently. The purpose of the present invention is to provide a cylindrical container that can be formed without requiring a large amount of force.

[0007]

The cylindrical container of the present invention is intended to achieve the above-mentioned object by means of an elastic material such as polyethylene for fitting the inner peripheral surface of the opening of the lid to the outer peripheral surface of the opening of the container body. In the cylindrical container formed by the above, either a spiral ridge or a concave ridge is formed on the outer peripheral surface near the open end of the container body, and the open end of the lid fitted therein is formed. A spiral groove or thread that is screwed into the ridge or groove is formed on the inner surface in the vicinity, and a discontinuity is formed at a position close to the end of the spiral ridge or groove. Is formed.

[0008]

In the cylindrical container of the present invention, since the spiral protrusions and recesses are formed on the container body and the lid, these can be screwed together when the lid is fitted on the container body. The two can be screwed together smoothly without any difficulty.

When the screw is screwed in the vicinity of the start end, the projection and the recess are screwed together, so that the lid can be easily rotated with respect to the container body and the screw is screwed near the end. It is possible to proceed smoothly.

When the screwing reaches a flat discontinuous portion near the end, the lower portion of the ridge is fitted into the lower portion of the recessed portion, so that the lid and the container body unintentionally release the screwing. It is impossible to rotate in the direction, and the closed state is secured, but if you apply force and rotate in the screwing release direction, the spiral shape will serve as a guide and you can rotate in the opening direction and open the lid. It will be possible.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to the drawings. In this embodiment, the container body 1 and the lid 2 are made of a highly elastic plastic material such as polyethylene, and the container body 1 has a spiral ridge protruding to the outer peripheral surface in the vicinity of the opening at the upper end thereof. 3 is formed.

A discontinuous portion 4 which is the same as a flat surface other than the protrusion 3 is formed near the opening end of the spiral protrusion 3. The discontinuous portion 4 may have a shape protruding from the flat surface toward the inner peripheral surface side.

Further, the lid 2 is formed with a spiral recess 6 which is continuous from a large diameter portion 5 provided adjacent to the opening at the lower end thereof and which is recessed from the outer peripheral surface side. A discontinuity 7 that is the same as the flat surface other than the recessed line 6 is formed near the end of the line 6 apart from the opening. The discontinuous portion 7 may have a shape protruding from the flat surface toward the inner peripheral surface side.

When the lid 2 is fitted to the container body 1,
The large-diameter portion 5 on the opening end side of the lid 2 is fitted from the opening end side of the container body 1, but the recessed ridges 6 and the ridges 3 of the lid 2 come into contact with each other, and the lid 2 is attached to the container body 1 there. When is rotated in the spiral screwing direction, screwing of the protrusion 3 and the recess 6 is started.

When this screwing is started, the groove 6 of the lid 2 will soon reach the discontinuous portion 4 of the protrusion 3. However, since the groove 6 only passes over the discontinuous portion 4, the groove 6 is depressed. The rotation of the two in the screwing direction can be continued without affecting the screwing with.

When the discontinuous portion 7 of the recess 6 reaches the discontinuous portion 4 of the ridge 3, the discontinuous portion 7 abuts on the ridge 3, so that the screwing of the both becomes heavy, but the material is Since it is made of elastic plastic such as polyethylene, the ridge 3 pushes up the discontinuous portion 7, and further pushes the screwing of the two in this state.

Then, when the discontinuous portion 7 reaches the position of the discontinuous portion 4, both are in the engaged state and the lid 2 is fitted on the container body 1. In this state, the discontinuous portion 7 and the discontinuous portion 7 are discontinuous. Part 4
With this, the lid 2 or the container main body 1 cannot be unintentionally rotated in the screw releasing direction, and the closed lid state is secured.

However, if the container body 1 or the lid 2 is strongly rotated in the direction for releasing the engagement, the engagement is released, and the container body 1 and the lid 2 are recessed into the spiral projection 3 and the concave portion. The guide of the strip 6 can rotate in the screw-disengaging direction, and the lid can be opened with the screw-disengagement of the protrusion 3 and the recess 6. Reference numeral 8 in the drawing is a suspending hole provided in the lid 2 for suspending the cylindrical container.

In the above embodiment, the protrusion 3 is formed on the container body 1 and the recess 6 is formed on the lid 2. However, a spiral groove recessed from the outer peripheral surface of the container body 1 is formed on the inner periphery of the lid 2. Even if a projecting ridge protruding inward from the surface is formed, and a discontinuous portion is formed near the end of this recess, and a discontinuous portion is formed at the starting end portion of the corresponding ridge, it is possible to obtain The same effect can be achieved.

[0020]

As described above, according to the present invention, the resistance increases due to the fitting between the container body and the lid, and the fitting between the container body and the flat or lower portion provided therewith. Since the guides are guided by screwing the ridges and recesses, the fitting is performed in the same way as the screwing, and the operation of fitting the lid to the container body is done by fitting the conventional ring-shaped ridges and recesses. It is much easier than

[0021] Since the discontinuous portions are fitted together, the lids do not slip out, so that the lids are securely fitted together, and the engagement with the discontinuous portions is spiral even when the lids are opened. Since it is performed by the guide of the ridges and the ridges, the engagement and disengagement thereof is easy, and therefore, the work of removing the lid is easier than the conventional one.
