Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a container and cap positioning device that stops a cap fitted in a container at a specific position.

[Conventional technology]

Conventionally, as a positioning device for a container and a cap, there is a device such as Japanese Utility Model Application Laid-Open No. 57-145836.

As shown in FIGS. 5 and 6, in this publication, the outside of the base 25 of the mouth and neck part 3 of the container 1 is formed into a square surface, and the corners of the square are chamfered. forming an abutting surface 26, and
An inner cylinder 30 is provided on the cap 13 which is screwed onto the cap 13, and the lower end of the inner cylinder 30 is formed into an elastic plate 14. When the cap 13 is screwed onto the mouth and neck part 3, the elastic plate 14 is attached to the mouth and neck part. 6, the inner surface of the elastic plate 14 matches the abutment surface 26, and the container 1 and the cap 13 are stopped at predetermined positions.

[Problem that the invention attempts to solve]

As shown in Figures 5 and 6 above,
When the width of the abutment surface 26 is increased, the elastic plate 14 of the cap 13 is moved between the front end 28 and the rear end 2 of the abutment surface 26.
If the width is narrowed, the cap 13 will not stop at the specified position and will tend to go a little too far.
It also became a cause of unsteadiness.

The present invention was made in view of the above drawbacks,
The technical problem is to enable a cap 13 to rotate with a small force and to surely stop at an accurate position.

[Means for solving problems]

In the present invention, a mouth and neck part 3 is erected on a container 1, a screw 4 is provided on the mouth and neck part 3, and at least one pair of contact surfaces 6 are formed perpendicularly to a base 5 of the mouth and neck part 3. . The end portion is a rear end portion 9, and the distance R1 from the center of the mouth and neck portion 3 to the front end portion 8 is longer than the distance R2 from the center of the mouth and neck portion 3 to the rear end portion 9,
Furthermore, the height h1 of the front end part 8 is formed lower than the height h2 of the rear end part 9, and the mouth and neck part 3
Elastic plates 14, 14 abutting against the contact surfaces 6, 6 are provided on both lower sides of the cap 13, which is screwed into the cap 13, to serve as a positioning device for the container and the cap.

[Effect]

In the present invention, since the distance R1 from the center of the mouth and neck part 3 to the front end part 8 is longer than the distance R2 from the center of the mouth and neck part 3 to the rear end part 9, the abutment surface 6 has a front end part 8 that is threaded. The width is wider at the front in the tightening direction of 4. Therefore, a cap 1 is attached to the mouth and neck part 3 of the container 1.
3 are screwed together, the elastic plate 14 of the cap 13 becomes
First, it comes into contact with the front end portion 8 . However, the cap 13 has not yet been fitted all the way to the bottom, and the height h1 of the front end 8 is formed low, so the elastic plate 14 gets over the front end 8 without receiving much resistance. Furthermore, when the cap 13 is rotated, the elastic plate 14 comes into contact with the rear end 9 of the next contact surface 6.
Since the distance R2 is shorter than R1, the abutment surface 6 is formed to have a shorter width toward the rear end 9.
The elastic plate 14 can ride over the rear end 9. The cap 13 is prevented from rotating and stops at the position where the elastic plate 14 overlaps and matches the abutment surface 6, but since the abutment surface 6 is formed with a wide width, the elastic plate 14 does not wobble. The cap 13 is fixed.

〔Example〕

1 to 4 show an embodiment of the present invention, in which a container 1 has a mouth and neck part 3 erected, a screw 4 is provided on the mouth and neck part 3, and a screw 4 is provided on the mouth and neck part 3. A pair of contact surfaces 6, 6 formed perpendicularly to the base 5 of 3
are provided in parallel on both sides of the base 5, and the position where a perpendicular drawn from the center of the mouth and neck part 3 to the side wall 2 of the container 1 intersects with the abutting surface 6 is defined as an intersection 7, and from the intersection 7 a screw is inserted. 4, the distance l1 to the front end 8 located at the front in the tightening direction is 8 mm, the distance l2 from the intersection 7 on the contact surface 6 to the rear end 9 of the contact surface 6 is 6 mm, and l1 is from l2. It also formed for a long time. In this case, the distance R1 from the center of the mouth and neck part 3 to the front end part 8 is about 14.5 mm, the distance R2 from the center of the mouth and neck part 3 to the rear end part 9 is about 13.8 mm, and the distance R1 is formed longer than distance R2.

Furthermore, as shown in FIG. 4, whereas the conventional abutting surface 26 intersects at an angle of 90 degrees with the perpendicular line drawn to the side wall 2 (not shown in FIG. 4), this embodiment The abutment surface 6 is further inclined by two degrees so that the front end 8 is inward. In this conventional type, l3=l4=5 mm.

Further, the height h1 of the front end 8 is 4 mm, which is lower than the height h2 of the inner end 9, which is 5.5 mm. Further, elastic plates 14, 14 are formed on both sides of the lower part of the cap 13, which is screwed into the mouth and neck part 3, and come into contact with the contact surface 6, and the inside of the cap 13 is provided with packing 15. ing.

In this embodiment, the elastic plate 14 is formed on the inside of the cap 13 substantially parallel to the side wall of the cap, but the side wall of the cap may be formed of an elastic plate. The abutment surface 6 is tilted twice to match the elastic plate 14, but the angle of the abutment surface 6 with respect to the perpendicular line can be changed accordingly if the position of the elastic plate 14 is changed. be able to.

Further, the abutment surface 6 can be shaped so that the lower part thereof is not perpendicular to the center line of the mouth and neck part 3,
Furthermore, the abutment surface 6 may not be a perfectly linear plane.

[Effect of idea]

The present invention has a contact surface 6 provided on the mouth and neck portion 3 of the container 1.
Since the height h1 of the front end 8 of the cap is formed to be lower than the height h2 of the rear end 9, the elastic plate 14 can easily climb over the front end 8 when the cap 13 is rotated. The distance R1 to the portion 8 can now be made longer than the distance R2 from the center of the mouth and neck portion 3 to the rear end portion 9. As a result of lengthening R1, the width of the abutment surface 6 has become wider, so when the cap 13 is rotated, the elastic plate 14 can easily climb over the end of the abutment surface 6, but the cap 13 cannot be fixed. It can be stopped firmly in position.
