Description

[Detailed Description of the Invention] <<Industrial Application Field>> This invention relates to a container with a cap, in which the cap is attached to the container in a vertically removable manner by elastic fitting.

《Prior art》 Conventionally, this type of “container with cap” was disclosed in Japanese Utility Model Application Publication No. 118647/1983 and Japanese Unexamined Utility Model Publication No. 60-68044.
Those proposed in Japanese Utility Model Publication No. 60-65245 are known.

Utility Model Application Publication No. 60-118647 is equipped with a flexible cylinder,
As well as incorporating this flexible cylinder into the cap body,
At least one of the contact surfaces between the lower end of the flexible cylinder and the container is an inclined surface. By pressing the flexible cylindrical body and bending it inward in the radial direction of the container, an upward moving force is generated in the flexible cylindrical body on the inclined surface, and this moving force is used to move the flexible cylindrical body and the cap integrally. was removed from the container.

Further, Japanese Utility Model Application Publication No. 60-68044 has a structure in which an operating ring is provided, the operating ring is incorporated into the cap, and both of the contact surfaces between the operating ring and the container are inclined surfaces. Then, by pressing the operating ring and elastically deforming it inward in the radial direction of the container, an upward moving force is generated on the operating ring on the inclined surface, and this moving force causes the cap integrated with the operating ring to be removed from the container. That's what I was doing.

Furthermore, Japanese Utility Model Application Publication No. 60-65245 is equipped with a cylindrical lever, which is incorporated into the cap, and in which the cylindrical lever and an internal circumferential wall integrally molded inside the cap are brought into contact with each other on an inclined surface. It is something. By pressing the cylindrical lever and elastically deforming it inward in the radial direction of the container, an upward moving force is generated on the internal circumferential wall formed on the cap by the inclined surface, and this moving force is used to move the cylindrical lever and the The cap could be removed from the container.

<<Problem to be solved by the invention>> By the way, in any of these conventional techniques, when providing a cap opening mechanism, the cap or container is The function and structure of the main body were modified to include a cap opening mechanism. For this reason, the cap structure in which the cap opening mechanism is incorporated becomes complicated, and the container must have a shape such as an inclined surface for the cap opening mechanism. Moreover, it is thought that the manufacturability will deteriorate and the assembly work will become complicated. In other words, in order to provide a cap opening mechanism, the idea was to modify the cap, the container, or both, which required an excessively complex structure and shape for the cap or container, and as a result, the manufacturability was reduced. This has led to deterioration and complicated assembly work.

This idea was devised in view of the conventional problems mentioned above, and its purpose is to provide a cap opening mechanism without making any special functional or structural changes to the cap or container. The object of the present invention is to provide a container with a cap that can be simply formed in its original form, and can therefore be easily equipped with a cap opening mechanism while maintaining good manufacturability and assembly workability. .

<<Means for Solving the Problems>> In order to achieve the above object, this invention provides a container with a cap that includes a container and a cap that is detachably attached to the container in the vertical direction by elastic fitting. , comprising a cap opening means that is engaged with and held on the container side and interposed between the container and the cap, the cap opening means being connected to the upper surface of the main body of the container opposite to the lower end of the peripheral wall of the cap. a flexible ring that is slidably provided on the container and pushed inward in the radial direction of the container along the upper surface; It consists of an annular inner frame arranged opposite to the lower end of the peripheral wall,
It is characterized by

<<Function>> To describe the function of the present invention, the cap is engaged with and held on the container side and is interposed between the container and the cap.
A cap opening means consisting of a flexible ring and an inner frame is separately installed, and the flexible ring and the inner frame are stacked one on top of the other with an inclined surface interposed therebetween. When the flexible ring is pushed into the container, this pressing force can push up the middle frame facing the lower part of the cap (lower end of the peripheral wall of the cap) toward the cap through the inclined surface, thereby removing the cap from the container. be able to.

In particular, the structure of the present invention is not based on the concept of modifying the cap or container in order to provide the cap opening mechanism.
These can be simply formed in their original form, and their manufacturability and workability can be maintained favorably. The cap opening means of the present invention can be used for caps and containers that have a simple structure.
Since the caps are simply added together, the structure can be simplified and the container with a cap can be equipped with a cap opening mechanism.

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

This embodiment basically consists of a container 1 and a container 1.
In a container with a cap, which has a cap 11 which is detachably attached in the vertical direction by elastic fitting to the container, the cap is opened by being engaged and held on the container 1 side and interposed between the container 1 and the cap 11. The cap opening means is slidably provided on the upper surface 4 of the main body 3 of the container 1 facing the lower end of the peripheral wall 13 of the cap 11, and the cap opening means is slidably provided on the upper surface 4 of the main body 3 of the container 1 facing the lower end of the peripheral wall 13 of the cap 11, and the cap opening means A flexible ring 8 that is pushed in, and a peripheral wall portion 13 of a cap 11 that is provided overlappingly on the flexible ring 8 with an inclined surface 10 interposed therebetween.
It consists of an annular inner frame 9 disposed opposite to the lower end.

First, the first part of the present invention shown in Figs.
In the container with a cap according to the embodiment, the container 1 has a flexible material made of synthetic resin on the upper surface of the main body 3 of the container main body 2 as a cap opening means interposed between the container 1 and the cap 11. The elastic ring 8 and the middle frame 9 are provided in a superposed state. The container body 2 has a general configuration, and includes an inclined portion 5 that slopes upward from the center of the upper surface portion 4 of the cylindrical main body portion 3, and an open neck portion 6 at the center of the inclined portion 5.
is formed protrudingly. An annular locking protrusion 7 having a substantially trapezoidal cross section is integrally formed on the outer periphery of the tip of the open neck portion 6 . The flexible ring 8 has a semi-elliptical cross section, has an outer diameter larger than the outer diameter of the container body 3, has a smaller inner diameter, and is placed on the upper surface of the container body 3. The inner frame 9 has a disk shape with an inner diameter slightly larger than the outer diameter of the neck portion 6 but smaller than the outer diameter of the locking protrusion 7, and an outer diameter smaller than the outer diameter of the container body portion 3. , has an inclined surface 10 that is inclined from the outer periphery of the upper surface toward the inner periphery of the lower surface. This middle frame 9 has, for example, a vertical cut, and is assembled into the container by forcefully press-fitting it through the neck portion 6 of the container, and is positioned above the flexible ring 8.

On the other hand, the cap 11 is a synthetic resin molded product with sufficient rigidity, and includes a disk-shaped ceiling surface 12 with a diameter approximately the same as the outer diameter of the container body 3, and a cylindrical peripheral wall portion 13 that hangs down from the periphery of this ceiling surface 12. And this peripheral wall part 1
3 has a plurality of flexible claw pieces 14 formed by drilling slits in a cylindrical part that hangs down from the lower surface of the ceiling surface 12, and can be moved up and down by simply elastically fitting into the container 1. It consists of only a basic structure that allows it to be attached and detached in both directions.

A cutout surface 15 is formed by cutting out a portion of the inner circumferential side of the lower end of the peripheral wall portion 13, and a substantially trapezoidal locking protrusion 16 is bored in the inner circumferential side of the flexible claw piece 14. Further, a packing 17 is provided on the ceiling surface 12 inside the flexible claw piece 14.

In the state shown in FIG. 2A, the cap 11 is completely fitted into the container 1. In other words, cap 11
The locking projection 16 on the side elastically rides over the locking projection 17 on the container side, and the cap 11 is positioned in the correct closed position with respect to the container 1. This state is
The cap 11 is simply fitted onto the container 1,
Corresponds to the previous structure. In this state, the cutout surface 15 of the peripheral wall of the cap 11 and the lower end surface of the flexible claw piece 14 are in contact with or close to the upper surface of the middle frame 9, and the outermost side of the inclined surface 10 of the middle frame 9 is A flexible ring 8 abuts.

To remove the cap 11 from the above condition,
As shown in FIG. 2B, the flexible ring 8 is pressed inward with a finger. At this time, the flexible ring 8 is pushed inward while slidingly contacting the inclined surface 10 of the middle frame 9, so that the middle frame 9 receives a force from the flexible ring 8 in a direction perpendicular to the inclined surface. This includes the force that pushes the middle frame 9 upward. That is, since at least one of the surfaces where the flexible ring 8 and the middle frame 9 come into sliding contact with each other is an inclined surface 10, when the flexible ring 8 is pushed inward, the middle frame A force that pushes up the cap 11 acts on the cap 9.
Therefore, the middle frame 9 moves upward and pushes up the cap 11, which is in contact with the upper surface of the middle frame 9 and is simply elastically fitted to the container 1, so that the locking protrusion 16 becomes the locking protrusion. 17, and the cap 11 is removed from the container 1.

By the way, in this embodiment, in providing the cap opening mechanism, the cap 11 and the container 1 can be provided without any particular functional or structural modification.
These can be simply formed in their original form, and their manufacturability and assembly workability can be maintained well. The cap opening means of this embodiment is as follows:
The cap 11 and the container 1, which have such an original simple structure, are simply added together, so that the structure can be simplified and the cap-equipped container can be equipped with a cap opening mechanism.

In addition, in this embodiment, container 1 and cap 1
Since the cap can be easily removed even if the strength of the fitting is increased, a container with a cap that has good sealing performance and is easy to use can be obtained. Furthermore, since the fitting strength can be increased, the material can be selected freely, and there is also a degree of freedom in design, so that a luxurious appearance and texture can be obtained.

FIG. 3 shows a second embodiment in which the present invention is applied to a liquid container for perfume, cologne, etc.
Figure A shows the cap fully closed, and Figure 3 B
is synthesized with the operating state when the cap is removed.

In this embodiment, the container 1' has an inner stopper 18 that is fitted into a groove 19 formed on the outer periphery of the opening neck part 6', and this inner stopper 18 is fitted into the inner surface of the neck part 6'. It has a cylindrical portion having a bottom surface at its mating end, and a locking protrusion 20 is protruded from this cylindrical portion. Further, a small circular hole 21 is bored in the bottom of the inner stopper. The flexible ring 8' and the inner stopper 9' are the same as in the first embodiment.

On the other hand, the cap 11' has a cylindrical peripheral wall part 13' that hangs down from the peripheral edge of the ceiling surface 12' and has a cutout surface 15' on the inner peripheral side of the lower end, and a locking protrusion 22 at the center of the lower surface of the ceiling surface 12'. A cylindrical stopper 23 having a diameter is provided in a protruding manner.

In the state shown in FIG. 3A, the cap 11' is completely fitted into the container 1', and the locking protrusion 22 of the cap 11' is positioned over the locking protrusion 20 of the container 1' in the correct closed position. has been done. In this state, the cutout surface 15' of the peripheral wall of the cap and the upper surface of the middle frame 9' are in contact with or close to each other, and the flexible ring 8' is in contact with the outermost side of the inclined surface 10' of the middle frame 9'. ing.

To remove the cap 11' from the above condition,
As shown in Figure 3B, the flexible ring 8' is pressed inward with a finger. At this time, the flexible ring 8' is pushed inward while slidingly contacting the middle frame 9' and the inclined surface 10', so that the middle frame 9' flexibly absorbs the force in the direction perpendicular to the inclined surface 10. This includes the force that pushes the inner frame 9' upward. Therefore, the middle frame 9' moves upward and pushes up the cap 11' which is in contact with the upper surface of the middle frame 9', so that the locking projection 22 gets over the locking projection 20 and the cap 11' is attached to the container. It deviates from 1'.

In the embodiments described above, the inner frames 9, 9' are provided with inclined surfaces 10, 10', and when the flexible rings 8, 8' are pushed in, the inner frames are pushed upward through the inclined surfaces. The configuration is such that a component force acts and the middle frame pushes up the cap,
The present invention is not limited to this, but the flexible ring may be provided with an inclined surface, and the inner frame may be configured to slide into contact with this inclined surface.

<<Effects of the invention>> The container with a cap according to the invention configured as described above has a container and a cap that is detachably attached to the container in the vertical direction by elastic fitting. In the container,
A cap opening means is provided which is engaged and held on the container side and is interposed between the container and the cap, and the cap opening means is slidably provided on the upper surface of the main body of the container opposite to the lower end of the peripheral wall of the cap. a flexible ring which is pushed inward in the radial direction of the container along the upper surface; Since it is composed of a ring-shaped inner frame, when installing a cap opening mechanism, it is possible to simply form the cap or container in its original form without making any special functional or structural changes to the cap or container. This makes it possible to maintain good manufacturability and assembly workability. The cap opening means of the present invention simply adds an overlapping flexible ring and an inner frame to the original simple structure of the cap and container. A cap opening mechanism can be provided.
