Description

[Detailed description of the invention] This invention relates to a container with a cap, and is provided so that when the cap is tightened, the engaging portions provided on the container body side and the cap side are elastically fitted and positioned. be.

Various mechanisms of this type have been known in the past, but
For example, caps that utilize elasticity by imparting elasticity to the peripheral wall of the cap generally have the disadvantage that the elastic fit tends to become stiff.

Also, since this kind of cap is a screw-on type cap and the screw cannot be made elastic, it is natural that an elastic peripheral wall must be provided as an outer peripheral wall in addition to the screw tube, and the screw tube and the outer peripheral wall must be provided separately. There was a drawback that the appearance of the cap was spoiled because a gap was formed between the cap and the cap.

The present invention eliminates such drawbacks, and will be explained below with reference to the drawings. Reference numeral 1 indicates a container body.

The body 2 has a cross-sectional shape other than a perfect circle, such as a polygon or an ellipse, and from the upper end of the body there is a shoulder 3.
A mouth and neck portion 4 for screwing the cap protrudes through the cap.

The shoulder portion 3 is provided with a first engagement protrusion 5°5.

The cap 6 is screwed onto the neck of the capacitor, and
A peripheral wall having the same cross-sectional shape as the body of the container is suspended from the periphery of the top wall, and is formed by an outer body 7 and an inner body 8.

The external body 7 has a peripheral wall hanging from the periphery of the top wall, and protrusions 14, 14 are vertically installed on the inner surface of the peripheral wall.

The inner body 8 has an inwardly flange-shaped top wall 9 attached to the upper end of the circumferential wall, which has a threaded portion 13 on the inner surface to be screwed into the capacitor neck, and a protrusion is attached from the inner periphery of the top wall to the inner periphery of the lower end. A short cylindrical portion 10 is provided vertically, and the top portion 12 of the backing 11 is fitted into the short cylindrical portion, and an outward elastic flange 16 is attached to the lower end of the peripheral wall.

The outer surface of the peripheral wall has a concave groove 15. into which the previously mentioned protrusion 14.14 is fitted.
15 are installed vertically, and the elastic flanges 16 close the lower ends of the peripheral wall of the picture body with the inner body integrally fitted into the outer body by fitting the protrusions and the grooves. This is how it is set up.

On the lower surface of the elastic flange, a loosening-stopping protrusion and a second engaging protrusion 17.17 are attached at appropriate intervals. 2. The engagement protrusion is made so large that it cannot be climbed over, and when tightening the cap,
As shown in FIG. 3, when the first engagement protrusion 5 is held between the loosening protrusion 18 and the second engagement protrusion 17, the outer surface of the cap peripheral wall is in contact with the outer surface of the capacitor trunk. It's designed to be whatever happens.

Note that the circular body top wall 9 may be formed in a disk shape instead of a flange shape.

In this case, the backing is fitted to the outer periphery of the lower surface of the top wall.

The present proposal adopts the above arrangement, and the cap has an inner body 8 having a peripheral wall with a threaded portion 13 screwed onto the neck between the container bodies inserted into an outer body 7 having a peripheral wall hanging from the periphery of the top wall. let me,
The outer body 7 and the inner body 8 are fitted together by fitting the grooves 15 with the plurality of protrusions 14 vertically provided on the inner surface of the outer wall of the outer body and the outer surface of the circular wall. Therefore, when tightening or loosening the cap, the torque applied to the cap outer body is applied to the vertically installed protrusions 14 and the grooves 1.
5, the torque is transmitted directly from the peripheral wall of the external body to the peripheral wall of the circular body, so that the elastic flange 16 is not subjected to the above torque.

That is, if the protrusion 14 and the groove 15 are not engaged, torque will be transmitted from the peripheral wall of the external body to the peripheral wall of the circular body via the elastic flange 16, and the elastic flange will be elastically deformed by the torque. Although it should be difficult, in this case, since the torque is not applied, elastic deformation can be made easier.

Therefore, the locking protrusion 1 attached to the lower surface of the elastic flange
8. When 18 gets over the first engagement protrusions 5, 5 attached to the upper surface of the shoulder of the container body, the elastic flange 16 is reliably elastically deformed, and at the same time it gets over, it elastically returns to its original state, thereby achieving the function of the elastic flange. can be increased.

Since the elastic flange is not subjected to the above torque, the wall thickness of the elastic flange can be freely selected, and it is easy to fit the cap to the container body appropriately.

In addition, a second engaging protrusion 17.17 and a locking protrusion 18.18 are attached to the lower surface of the elastic flange 16, and when the cap is tightened, the locking protrusion 18.18 is attached to the shoulder of the container body. It overcomes the elasticity of the elastic flange and overcomes the first engagement protrusion 5 attached to the elastic flange, and the second engagement protrusion 17, 17 contacts the first engagement protrusion 5, 5 without being able to get over it, and pinches the first engagement protrusion 5, 5. In addition, since the outer surfaces of the peripheral walls of the container body and the cap outer shape are located flush with each other, their alignment is reliable, and the first engagement against the elasticity of the elastic flange of the locking protrusion is ensured. Sufficient response for tightening the cap can be obtained by getting over the mating protrusion and pressing the second engaging protrusion against the first engaging protrusion, and furthermore, there is elasticity between the lower end of the peripheral wall of the outer body and the lower end of the peripheral wall of the inner body. Since it is closed by the flange 16, the cap can have an excellent appearance.
