Description

[Detailed Description of the Invention] The present invention is such that the cap can be securely tightened, the container body and the cap can be aligned reliably, and the cap can be prevented from loosening.

Conventionally, devices having these functions individually have been known, but the present invention is designed to more reliably and easily perform these functions by combining these functions in a mutually supportive manner.

To explain the drawings below, 1 is a container body, 2
3 is the body part, 3 is the shoulder part, and 4 is the neck part for screwing the cap. This shoulder portion is provided with first engaging protrusions 5,5. The cross-sectional shape of the body portion 2 is formed into a quadrilateral or other polygon.

6 is a cap. The cap consists of a cap body 7 and an inner plug 21, and the cap body is formed of an outer body 8a and an inner body 8b.

The cap outer body 8a has a first circumferential wall 9 having the same cross-sectional shape as the body of the container, and on its inner surface are vertically provided protrusions 10, 10 for fixing the inner body 8b.

The inner body 8b has an outer diameter that is approximately the same as the inscribed circle of the first peripheral wall 9, and has a threaded portion 1 on the inner surface for screwing the neck part.
1, and an inward flange 14 protrudes from the upper end thereof. As shown in the figure, the flange has a third portion extending from its inner circumferential edge to its lower inner circumferential edge.
The short cylindrical portion 16 provided with the engagement protrusion 15 may be provided vertically. Further, on the outer surface of the second peripheral wall 12, grooves 17, 1 are provided for fitting the protrusions 10, 10 of the external body.
7 is installed vertically. Further, a plurality of corner pieces 18 are attached to the lower end surface of the peripheral wall for closing the gap with the lower end of the outer body peripheral wall, and the corner pieces have elasticity and have a plurality of corner pieces 18 on the lower surface thereof with appropriate gaps. 2 engaging protrusions 1
9, 19 and locking protrusions 20, 20 are attached.

21 is the flange hole 1 of the inward flange 14
The upper part of the cap-shaped part 22 is fitted into the cap-shaped part 3 so as to be movable up and down, and the large-diameter tapered wall 24 is fitted into the neck part 4 from below and upward from the circumferential wall of the cap-shaped part to make it stand up. The outer flange 25 is placed on the top surface of the mouth of the container from the upper end of the tapered wall, and
This is an inner plug in which the distal end of the outward flange-shaped portion is erected obliquely upward and outward, and the peripheral edge 26 of the distal end is brought into contact with the lower surface of the inward flange 14. Cap-shaped portion 22
A fourth engagement protrusion 22a is provided on the outer periphery of the upper end to prevent the flange from falling out of the flange hole 13, and in the illustrated example, the third engagement protrusion 1
5, and an overhanging portion 27 is provided between the lower end of the peripheral wall of the cap-shaped portion and the lower end of the tapered wall 24.
It is a good idea to provide

When the cap to which the inner stopper 21 is attached is screwed onto the mouth and neck of the container body and tightened, the tapered wall 24
enters the mouth and neck part 4, and as a result of its tightening, the upper inner peripheral edge of the mouth and neck part comes into pressure contact with the upper outer surface of the tapered wall, thereby being elastically deformed and deeply fitted, and at this time, the locking projections 20, 20 passes over the first engagement protrusions 5, 5, and the second engagement protrusions 19, 19 contact the first engagement protrusions 5, 5 in such a way that they cannot be overcome, and are engaged in the first engagement with the loosening protrusions. The protrusions shall be sandwiched, and at this time, the container body body and the peripheral wall of the cap body shall be located flush with each other. In this state, the loosening protrusion 20,
20 engages with the first engagement protrusions 5, 5, the cap does not loosen, and when the cap is turned in the direction of loosening from this state, the locking protrusions 20, 20 engage with the first engagement protrusions 5, 5.
It screws over the engaging protrusions 5, 5, and as the cap rises, the tapered wall 24 returns to its original state, allowing it to be screwed off.

The present invention has the above-mentioned structure, and the inner body 8b and the outer body 8a constituting the cap body are connected to the cylindrical second peripheral wall 1 of the inner body which is screwed onto the outer surface of the neck of the container body.
2, the inscribed circle of the polygonal first circumferential wall 9 of the external body into which the second circumferential wall is fitted is made approximately the same diameter as the second circumferential wall outer diameter, and the first and second circumferential walls are in contact with each other. Since the protrusions 10 and grooves 17 that fit into each other are provided on the contact surfaces to fix the outer body and the inner body, the fixation can be ensured, and therefore the lower surface of the first peripheral wall and the lower surface of the second peripheral wall can be secured. The elastic deformation of the corner pieces 18 attached to the lower end of the second circumferential wall is not hindered by the first circumferential wall 9 by closing the gap between the cap and the container. The second engaging protrusion 19 provided on the body shoulder, the locking protrusion 20, the first engaging protrusion 5, and other engaging means can be attached and detached and loosened securely by elastic deformation of the corner pieces 18. . The inner surface of the cap is formed by the inner shape body 8b and the inner plug 21, and the tapered wall 24 and the outward flange-shaped part 25 of the inner plug form a packing part, but the cap-shaped part 22 of the inner plug Since the packing part is formed by simply fitting the flange hole 13 into the flange hole 13 of the inner body, the packing part is easily formed, and the tapered wall 24 is watertightly fitted to the inner surface of the mouth and neck of the container body.
In addition, since the outward flange portion 25 is placed on the top surface of the mouth of the container body, liquid leakage can be doubly prevented by the tapered wall and the outward flange portion, and the tip of the outward flange portion Since the peripheral edge of the cap is in contact with the lower surface of the inward flange 14, there is no risk of dust entering the cap when the cap is removed.
