Description

[Detailed description of the invention] <<Industrial application>> This invention relates to a container with a cap, in which a cap is attached to the container body in a vertically removable manner by elastic fitting. This invention relates to a container with a cap that is composed of a stopper and a ring.

<<Prior Art>> As a conventional container with a cap of this type, the one disclosed in Japanese Utility Model Application Publication No. 118647/1983 has been known.

In this known container with a cap, a cylindrical flexible ring body is loosely fitted into the peripheral wall hanging down from the inside of the top plate of the stopper body, while an inclined surface is formed on the peripheral edge of the shoulder part of the container body. When the plug body is fitted into the container body, the lower end of the flexible ring body is located close to the above-mentioned inclined surface, and from this state, when the flexible ring body is deformed by being crushed inward. , the lower end of the flexible ring body rises along the inclined surface of the container body,
As a result, the stopper loosely fitted into the flexible ring rises and is removed from the container body.

However, in this known container with a cap, in order to push up the stopper, it is necessary to apply a horizontal force that crushes the flexible ring, and this force is usually applied by pressing the ring with two fingers. It is applied in a pinching manner, requiring strong force from the fingertips. In general, as the flexibility of the ring body increases, the upward force through the inclined surface is not effectively transmitted to the plug body, so the flexibility of the ring body must be reduced to a certain extent to create a repulsive force. Since it is necessary to use an object, the force applied to the fingertips has to be strong, resulting in poor operability.

On the other hand, Japanese Utility Model Application Publication No. 103955/1983 is known as a container with a cap that utilizes the rotational force of the stopper to lift the stopper and release it from the container body.

In this known container, engaging protrusions are formed on the lower inner surface of the cylindrical stopper, and sawtooth notches are formed at predetermined intervals in the circumferential direction at the lower end of the engaging protrusions. The ring body is formed with serrated protrusions corresponding to the notches, and the plug body and the ring body are overlapped so that these notches and the protrusions engage, and the two are coupled so that they rotate together. are doing. On the other hand, a pair of upper and lower annular ribs are formed in the mouth and neck of the container body, and the plug body and ring body that are engaged as described above are press-fitted into the mouth and neck, and the ring body is inserted between the upper and lower annular ribs. They are irremovably engaged and engaged so that the engagement protrusion of the stopper can be upwardly disengaged.

To disengage the stopper from the closed state of this known container, hold the ring body with one hand so as not to rotate it, and rotate the stopper with the other hand. is pushed up and at the same time, the protrusion of the stopper passes over an upper rib formed on the mouth and neck of the container body and is separated from the container body.

<<Problem to be solved by the invention>> As described above, when opening the container in the known manner mentioned above, it is necessary to grasp the ring body with one hand and rotate the stopper body with the other hand, which makes it difficult to use. It has become a bad thing. In addition, once the cap is opened, the ring body remains in the mouth and neck of the container body, and when the cap is closed again, the cap is placed in a ring so that the serrated protrusions of the ring body and the serrated notches of the closure match. It is necessary to fit the device while aligning it to the body, and this fitting process is quite troublesome. Furthermore, since the ring body remains on the mouth and neck of the container body after opening, when the liquid contents inside the container body are used, the liquid adheres to the ring body and is difficult to wipe off, posing a hygiene problem. .

This invention improves the above defects,
The purpose of this is to be able to release the engagement of the stopper with the container body by rotating only the stopper without having to grasp the ring body. To provide a container with a cap that is detachable from a main body, which simplifies closing operation and causes no hygienic problems.

<Means for Solving the Problems> In order to achieve the above object, the present invention provides a container with a cap, in which the cap is attached to the container body in a vertically detachable manner by elastic fitting, and The cap consists of a stopper and a ring, and the stopper has a top plate, a peripheral wall hanging from the top plate, and a sealing engagement means for engaging and sealing the opening of the container body. The peripheral wall has a first retaining means on the outer periphery and a plurality of first protrusions on the lower surface, and the ring body has a second retaining means on the upper inner surface and a second retaining means below. A flange is provided, a second protrusion is formed on the upper surface of the flange, and a first rotation prevention means is formed on the inner surface of the flange, and the first rotation prevention means of the plug body is connected to the ring body. The plug body and the ring body are assembled by engaging with the second retaining means, and the first and second retaining means allow the plug body to rotate relative to the ring body. At least one of the first protrusion and the second protrusion is an inclined surface, and a second rotation stopper is provided at the neck portion of the container body to fit the cap into the container body. When the ring body is rotated in the fitted state, the first rotation stopper engages with the second rotation stopper to prevent rotation of the ring body, and when the plug body is rotated in the above-mentioned fitted state, the first protrusion The second protrusion rides on the second protrusion, and the upward force causes the sealing engagement means of the stopper to separate from the opening of the container body.

<<Operation>> When the stopper is engaged with the opening of the container body, the first and second rotation preventing means are engaged, so the rotation of the stopper is prevented, and from this state the stopper is removed. When the container body is rotated, the first protrusion rides on the second protrusion, and the sealing means for sealing the opening of the container body provided on the closure separates from the opening and opens the closure. Thereafter, the stopper body and ring body are separated from the container body together. To close the container again, simply push the plug from above the opening of the container body. By this pushing, the sealing engagement means of the stopper engages with the opening of the container body, and the stopper is lowered relative to the ring body. At this time, when the first protrusion abuts against the second protrusion, the stopper is slightly rotated, and the first protrusion is positioned between the second protrusions, completing the closure.

<<Embodiments>> Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

First, in the container with a cap according to the first embodiment in which the present invention is applied to containers for perfumes, colognes, etc., shown in FIGS. 1 and 2, the cap 1 is made of relatively hard synthetic resin, and the stopper 2 is and ring body 3
It is composed of the following. The plug body 2 is a circular top plate 4
The bottom surface of the top plate 4 has an annular peripheral wall 7 having a retaining protrusion 5 on the outer periphery and a mountain-shaped projection 6 having a plurality of inclined surfaces on the bottom surface, and a bottom surface of the top plate 4. It has a cylindrical plug 9 that projects from the center and has a locking protrusion 8 on the outer periphery.

The ring body 3 has an annular retaining groove 10 on the inner circumferential side.
A flange portion 11 is formed with a step on the inside, and a plurality of mountain-shaped protrusions 12 having sloped surfaces are protruded from the upper surface of the flange portion 11. Further, a plurality of vertically long anti-rotation grooves 13 are bored in the inner periphery of the flange 11.
The outer diameter of the peripheral wall 7 of the stopper is equal to the flange 1 of the ring body 3.
It is made almost the same as the inner diameter above 1.

By press-fitting the plug body 2 from above the ring body 3, the retaining projections 5 provided on the peripheral wall 7 of the plug body 2 are accommodated in the retaining grooves 10 of the ring body, and the caps are rotatable with respect to each other. 1 is configured.

The container 14 has a cylindrical main body 15 having a bottom surface.
and a shoulder portion 16 forming a flat surface on its upper surface.
It consists of a neck part 17 which projects from the shoulder part 16 and has a vertically elongated rotation stopper projection 18 on a part thereof, and a mouth part 20 which further projects from the neck part 17 and into which the inner stopper 19 is fitted and locked. There is.

The inner plug 19 is made of a relatively soft synthetic resin and has flexibility, and the lower end of the outer periphery of the inner plug 19 has an annular protrusion 21 that fits and locks into a groove 25 formed on the outer periphery of the mouth portion 20. The top surface has a protrusion 22 for packing.
It has a cylindrical part which fits into the inner surface of the mouth part 20 and has a bottom surface at the end thereof, and an annular locking protrusion 23 is protruded from this cylindrical part. Further, a small circular hole 24 is bored in the bottom surface of the inner stopper.

In the state shown in FIG. 2A, the cap 1 is completely fitted into the container 14, and the locking projection 8 of the cap has passed over the locking projection 23 of the container and is positioned in the correct closed position. In this state, the anti-rotation protrusion 18 of the container neck fits into the anti-rotation groove 13 of the ring body 3, making it impossible for the ring body 3 to rotate around the container neck.
The protrusion 12 and the protrusion 6 of the stopper 2 are not engaged with each other.

To remove the cap 1 from the above state, rotate the stopper 2 to the right or left with your fingers, as shown in FIG. 2B. This rotation of the plug body 2 causes the protrusion 6 provided on the plug body 2 to engage with the protrusion 12 provided with the ring body 3. When further rotated, since the projection 6 has a mountain-shaped inclined surface and the ring body 3 cannot rotate around the container, the projection 6 rises while sliding on the inclined surface of the projection 12. That is, the stopper 2 is pushed upward.

Therefore, the locking protrusion 8 provided on the cylindrical plug of the plug body 2
is removed by climbing over the locking protrusion 23 provided on the inner stopper of the container, and then when the stopper body 2 is pulled upward, the retaining protrusion 5 of the stopper engages with the retaining groove 1 of the ring body.
0, the stopper body and the ring body are removed from the container 14. After removing the cap from the container, when the stopper 2 is pressed from above to close the cap, the rotation stopper groove 13 of the ring 3 fits into the stopper protrusion 18 of the container neck, and the stopper 2 is closed. descends. At this time, when the protrusion 6 collides with the protrusion 12, the lowering of the plug body 2 is prevented, but the ring body 3 rotates slightly, the engagement between the protrusions 6 and 12 is released, the plug body 2 is able to descend, and the cap is removed. Close container.

FIG. 3 shows a second embodiment in which the present invention is applied to a cream container, etc., and the explanation of parts having the same structure as the first embodiment will be omitted. The plug body 2 has a locking projection 25 provided on the inner periphery of the peripheral wall 7 of the plug body 2 instead of the cylindrical plug 9 having the locking projection 8 of the first embodiment. The cap is elastically fitted with a locking protrusion 27 provided on the outer periphery of the neck portion 26 of the container to close the cap on the container.

On the other hand, the ring body 3 is provided with a protrusion 28 instead of a groove on the inner peripheral side of the flange 11, and when the protrusion 28 fits into a groove (not shown) in the container neck, the ring body 3 The structure is such that it does not rotate around the container neck portion 26. When the container 14 and the cap 1 are fitted together, when the stopper 2 is rotated, the protrusion 6 of the stopper rides on the protrusion 12 of the ring body and the stopper 2 is pushed upward, so that the locking protrusion 25 locks into the container. The cap is removed from the container by climbing over the locking protrusion 27 of the cap.

Incidentally, in the above embodiment, both the protrusion 6 of the plug body 1 and the protrusion 12 of the ring body 3 are formed in the shape of a mountain with an inclined surface, but it is sufficient that either one of the protrusions has an inclined surface. It may be a vertical protrusion without an inclined surface.

In addition, although the cap 1 was constructed by accommodating the retaining protrusion 5 provided on the plug body 2 in the retaining groove 10 provided on the ring body 3, it is also possible to form a retaining groove on the plug body 2 to make the ring ring A retaining protrusion may be provided on the body 3, and the retaining protrusion of the ring body may be accommodated in the retaining groove of the stopper.

It goes without saying that the present invention can also be applied to containers having sloped shoulders. In that case, the lower surface of the ring body may be provided with an inclined surface that comes into contact with the inclined surface of the shoulder of the container.

<<Effect of the invention>> As described above, in the container with a cap according to the present invention, when the cap is fitted into the container body and the cap is closed, the rotation of the ring body is prevented, and the ring body is prevented from rotating. By rotating the stopper, the stopper is removed from the mouth of the container body, so it can be opened with one hand, making it easy to use. In addition, when the stopper is removed from the container body, the ring body is also removed from the container body, and when it is time to close the stopper again, all that is required is to push the stopper into the mouth of the container body from above, making the closing operation extremely easy. be. Furthermore, when the stopper is removed from the container body, only the ring body does not remain in the neck part of the container body as in the conventional case, so the contents will not stick to the ring body during use and become unsanitary. do not have.
