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, regarding this type of container with a cap,
The "container cap" proposed in Japanese Utility Model Publication No. 60-142743 and the "container with cap" proposed in Japanese Utility Model Application Publication No. 60-118647 are known.

The former proposes a cap opening mechanism built into the cap itself, and when the engaging protrusion on the cap side is moved upward and separated from the engaging protrusion formed on the mouth and neck of the container body, A push button having an engagement slope provided on the cap side is pushed radially inward into the container body. On this occasion,
Since the engaging protrusion on the cap side is formed on the engaging body installed inside the cap, the upward movement force of the engaging body can be obtained by pushing the engaging slope of the push button below the lower end of the engaging body. By doing so, the engaging protrusions are disengaged from each other.

In this prior art, a push button having an engagement slope that generates a push-up force and an engagement body that is to be moved upward in response to the push-up force are connected to each other at the top plate. was.

On the other hand, the latter has a structure in which a flexible cylindrical body is attached to a cap body, and at least one of the contact surfaces between the lower end of the flexible cylindrical body 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. could be removed from the container.

In this prior art, the cap opening mechanism is configured by a combination of a cap and a container, that is, a structure is adopted in which the container and the flexible cylindrical body are brought into direct sliding contact.

<<Problems to be solved by the invention>> By the way, in the former prior art, there is an engaging body having an engaging protrusion on the cap side that should go over the engaging protrusion on the container side, and an engaging body that should push up this engaging body. A push button with an engagement slope is connected at the top plate, and the engagement body that needs to move upward when the engagement protrusion on the cap side overcomes the engagement protrusion on the container body has a movement reaction force. It has a structure that does not permit relative displacement (relative movement) to the push button, which must be held in position in order to give a signal. Therefore, with this technique, it was not possible to ensure a smooth opening operation of the cap. In short, in this prior art, the above-mentioned problems arose as a result of trying to obtain even the push-up reaction force with the cap.

On the other hand, the latter conventional technology adopts a structure in which the container and the flexible cylindrical body are in direct sliding contact, so there is a problem that the sliding friction that affects the opening operation of the cap is affected by the material of the container. It was hot.

This idea was created in view of the problems of the conventional caps mentioned above, and its purpose is to suitably configure the cap opening mechanism as a built-in type, and to do so without affecting the opening operation of the cap. To provide a container with a cap that can appropriately set the applied sliding friction etc. only in the cap constituent members without depending on the material of the container, and can ensure a smooth opening operation of the cap.

《Means for solving the problem》 In order to achieve the above purpose, in this invention,
A container with a cap, in which the cap is attached to the container in a vertically removable manner by elastic fitting, and the cap is constructed by sandwiching a flexible ring between an upper lid and a lower frame, and the upper lid is provided with a locking protrusion that can be freely engaged with and detached from the neck portion formed on the container, and the lower frame is provided on the upper surface of the main body of the container that extends radially outward from the neck portion of the container. The upper lid and the lower frame are in contact with each other, and are provided with retaining means for restricting separation from each other while allowing the upper lid to move relative to the lower frame in the vertical direction. Slides between vertically opposing opposing surfaces of the upper lid and the lower frame via at least one of these opposing surfaces and an inclined surface so as to be pushed inward in the radial direction of the container. It is characterized by being freely installed.

《Function》 To describe the function of the present invention, the cap is
Consists of an upper lid that can be freely engaged and detached from the neck of the container, a lower frame that comes into contact with the upper surface of the main body of the container, and a flexible ring that is sandwiched between the upper lid and the lower frame via at least one inclined surface. In addition, since the upper cover and the lower frame are provided with retaining means for restricting their separation from each other while allowing the upper cover to move relative to the lower frame in the vertical direction, the cap opening mechanism can be built into the cap itself.

Then, when the flexible ring is pushed inward in the radial direction of the container, this pressing force pushes up the top lid through the inclined surface while taking a reaction force to the bottom frame side that is in contact with the top surface of the main body of the container. This causes the cap to come off the container.

In particular, regarding the upward movement of the upper cover at this time, the movement is smooth because the upper cover is allowed to move relative to the lower frame, which serves as a reaction force receiver, by the retaining means.

Moreover, the integrity of the upper cover, lower frame, and flexible ring is always maintained by employing the above-described retaining means.

Furthermore, since the cap can be opened only by sliding movement between the upper lid, lower frame, and flexible rings that make up the cap, smooth cap opening operation is ensured regardless of the material of the container. be able to.

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

This embodiment is basically a container with a cap in which the cap 1 is attached to the container 19 in a vertically removable manner by elastic fitting.
is constructed by sandwiching a flexible ring 9 between an upper lid 2 and a lower frame 12, and the upper lid 2 is provided with a locking protrusion 7 that can be freely engaged with and detached from a neck portion 22 formed on the container 19. , the lower frame 12 is brought into contact with the upper surface 21 of the main body of the container 19 that extends outward in the radial direction from the neck portion 22 of the container 19. The flexible ring 9 is inserted into the upper lid 2 so as to be pushed inward in the radial direction of the container 19. Between the opposing surfaces 4 and 17 that face each other in the vertical direction with respect to the lower frame 12, at least one surface of these opposing surfaces 4 and 17 and the inclined surface 1
0 and 11 in a slidable manner.

First, the first aspect of the present invention shown in FIGS.
In the container with a cap according to the embodiment, the cap 1
It is composed of an upper lid 2 made of synthetic resin, a flexible ring 9, and a lower frame 12. The upper lid 2 has a circular ceiling surface 3 having approximately the same diameter as the outer diameter of the container 19, and an inclined surface 4 of a predetermined length that slopes downward and inward from the outer periphery of the ceiling surface 3. A horizontal surface 5 is formed from the end of the surface 4, and a slit is bored in a cylindrical portion hanging down from the horizontal surface 5 to form a flexible claw piece 6. The flexible claw piece 6 has a locking protrusion 7 protruding from its inner circumferential side, and the flexible claw piece 6
A retaining protrusion 8 that protrudes toward the outer circumference is formed at the lower end. Further, a packing 25 is provided on the lower surface of the ceiling inside the flexible claw piece 6. The flexible ring 9 has an outer diameter slightly larger than the outer diameter of the container 19, an inner diameter slightly smaller than the outer diameter of the container 19, and a cross section formed in a substantially semicircular arc shape.
The ring 9 is formed inwardly in the radial direction so as to be easily bent, but not easily bent against a compressive force perpendicular to the ring 9. An inclined surface 10 is provided at a location where the upper lid 2 contacts the inclined surface 4, and an inclined surface 1 of the lower frame 12, which will be described later.
An inclined surface 11 is formed at a location where it contacts 7.

The lower frame 12 has a cylindrical portion 14, an upper surface 13, and a lower stand 15. The inner diameter of the upper surface 13 is approximately the same as the outer diameter of the claw piece 6 of the upper lid 2, and the outer diameter of the lower stand 15 is the same as that of the container 19. The outer diameter is approximately the same. Cylinder part 1
The upper surface 13 of 4 is stepped and horizontally protrudes inward, and the lower surface thereof constitutes a retaining surface 16. And these retaining surfaces 16 of the lower frame 12
and the above-mentioned retaining protrusion 8 of the upper lid 2,
A retaining means is configured to allow the upper lid 2 to move relative to the lower frame 12 in the vertical direction while restricting their separation from each other. The lower stand 15 is formed with an inclined surface 17 that slopes inward and upward from its outer periphery. Note that a channel-shaped groove 18 is formed between the inclined surface 17 and the cylindrical portion 14.

The cap 1 is configured with the upper lid 2, flexible ring 9, and lower frame 12 as described below.

First, the flexible ring 9 is placed on the lower frame 12.
At this time, the inclined surface 11 of the flexible ring 9 is connected to the lower frame 12.
It is located at the lower end of the inclined surface 17 of. Next, top lid 2
The claw piece 6 is inserted into the inner diameter of the upper surface 13 of the lower frame 12 by elastically bending inward so that the outer diameter of the retaining projection 8 becomes smaller than the inner diameter of the upper surface 13 of the lower frame 12. When the upper cover 2 is inserted into the lower frame 12, the inclined surface 10 of the flexible ring 9 is aligned with the inclined surface 4 of the upper cover 2.
The upper surface 13 of the lower frame 12 contacts the horizontal surface 5 of the upper lid 2, and the inner surface of the upper surface 13 of the lower frame 12 contacts the outer surface of the flexible claw piece 6 of the upper lid 2. . The retaining protrusion 8 of the flexible claw piece 6 is
It is housed in the lower frame 12 facing the retaining surface 16 of the lower frame 12 with a predetermined distance therebetween. Therefore, even if the upper cover 2 is lifted upward, the retaining protrusion 8 comes into contact with the retaining surface 16 of the lower frame 12, so that it does not easily come off when the upper cover 2 is raised by the distance between the opposing positions. .

On the other hand, the container 19 has a cylindrical main body portion 20 and a main body upper surface 21, and a cylindrical neck portion 22 having a smaller diameter than the main body portion 20 and raised from the main body upper surface 21. A substantially trapezoidal locking protrusion 24 is formed on the outer periphery of the neck portion 22 from its upper surface 23 . The lower base 15 of the lower frame 12 of the cap 1 is brought into contact with the upper surface 21 of the main body of the container.

In the state shown in FIG. 2A, the cap 1 is completely fitted into the container 19. In other words, the locking protrusion 7 having the flexible claw piece 6 of the upper lid 2 constituting the cap 1
The cap 1 elastically overcomes the locking protrusion 24 of the container 19 and is fitted together, and the packing 25 of the top lid 2 is in contact with the top surface 23 of the neck portion 22 of the container 19, so that the cap 1 is not attached to the container 19. is positioned in the correct closed position. In this state, ring 9
The upper and lower inclined surfaces 10 and 11 of the container 1 are in contact with the outermost inclined surfaces 4 and 17 of the upper lid 2 and lower frame 12 of the cap 1, and the lower stand 15 of the lower frame 12 is in contact with the upper surface 21 of the main body of the container 19. come into contact with

To remove the cap 1 from the above condition, press the flexible ring 9 inward with your finger as shown in FIG. 2B. At this time, the inclined surface 4 of the upper lid 2 and the lower frame 12
Since the inclined surface 17 of the flexible ring 9 is arranged inwardly in a wedge-shaped cross-sectional shape and the upper cover 2 is movable upward, the inclined surface 17 of the lower surface of the flexible ring 9
1 slides up the inclined surface 17 of the lower frame 12,
Moreover, the inclined surface 10 on the upper surface pushes up the upper lid 2 upward along the inclined surface 4 of the upper lid 2.

This is the same as the wedge action when driving a wedge, but in this case, the lower frame 12 is in contact with the top surface 21 of the main body of the container 19, so it cannot press the flexible ring 9 inward. As a result, the force with which the flexible ring 9 pushes the top lid 2 upward becomes larger. Therefore, the locking protrusion 7 of the flexible claw piece 6 of the upper lid 2 elastically rides over the locking protrusion 24 of the container 19, and the cap 1 is easily removed from the container 19. Note that even if the cap 1 comes off the container 19, the retaining protrusion 8 of the claw piece 6 will prevent the cap from coming off the retaining surface 16 of the lower frame 12.
Since the upper cover 2 is configured to come into contact with the lower frame 12, the upper cover 2 will not come off the lower frame 12.

According to this embodiment as described above, the cap 1
The upper lid 2 is removably connected to the neck portion 22 of the container 19, the lower frame 12 is in contact with the upper surface 21 of the main body of the container 19, and the inclined surfaces 10 and 11 are interposed between the upper lid 2 and the lower frame 12. The upper cover 2 and the lower frame 12 are provided with retaining means 8 and 16, which are configured of a flexible ring 9 that is sandwiched between the upper cover 2 and the lower frame 12, and which prevent the upper cover 2 from separating from the upper cover 2 and the lower frame 12 while allowing the upper cover 2 to move relative to the lower frame 12 in the vertical direction. Since the cap opening mechanism is provided with the cap opening mechanism, the cap opening mechanism can be built into the cap 1 itself.

In particular, regarding the upward movement of the top cover 2 at this time,
Since the upper cover 2 is allowed to move relative to the lower frame 12, which serves as a reaction force receiver, by the retaining means 8 and 16, this movement can be carried out smoothly.

In addition, the upper lid 2, the lower frame 12 and the flexible ring 9
Also, by employing the above-mentioned retaining means 8 and 16, the integrity of these is always maintained.

Furthermore, an upper lid 2 and a lower frame 1 constituting the cap 1 are
Since the cap 1 can be opened only by the sliding movement between the cap 1 and the flexible ring 9, the opening operation of the cap 1 can be influenced by appropriately selecting the materials of the members constituting the cap 1. The applied sliding friction, etc. can be set appropriately, and a smooth cap opening operation can be ensured regardless of the material of the container 19.

Another advantage is that the material for the cap 1 can be freely selected to give it a luxurious feel.

Since the inclined surfaces 10 and 11 are built into the cap 1, the container with the cap can be made more compact, and there is no need to provide an inclined surface shoulder on the container 19, so that the applications of the one-touch cap can be expanded.

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

In this embodiment, the top cover of the cap is located at the ceiling surface 3'.
An inclined surface 4' whose slope increases as it goes inward and downward from the outer periphery, and a flexible claw piece 6' suspended from this inclined surface 4' are formed. The flexible claw piece 6' has a retaining protrusion 8' projecting toward the inner circumferential side of its lower end. A horizontal surface 5' is formed inside from the upper end of the flexible claw piece 6', and a protrusion 26 projecting downward is provided at an intermediate position of this horizontal surface 5' for the purpose of packing. Furthermore, this horizontal plane 5'
A cylindrical stopper 27 is suspended downward from the inner end of the stopper. This cylindrical stopper 27 is located at the center of the lower surface of the upper lid, and a locking protrusion 28 having a substantially trapezoidal cross section is formed at the middle portion of the cylindrical stopper 27 and projecting outward from the circumference.

The lower frame 12' has a cylindrical part 14', an upper surface 13' and a lower stand 15', and the upper surface 13' of the cylindrical part 14' horizontally projects outward and is stepped. It constitutes a stop surface 16'. Similarly, in this embodiment, the retaining surface 16' and the retaining protrusion 8' on the top cover constitute a retaining means. The lower stand 15' is formed with an inclined surface 17' that slopes upwardly inward from its outer periphery.
A channel-shaped groove is formed between 7' and the cylindrical portion 14'.

The flexible ring 9' is the same as in the first embodiment, so a description thereof will be omitted.

The container 19' has a concave groove 29 on the outer periphery of the neck portion 22'.
is formed, and has an inner stopper 31 having a protrusion 30 that fits into this groove 29 and is locked to the container 19'. The inner stopper 31 is connected to the neck part 2 of the container 19'.
A cylindrical portion 32 having a bottom surface at the end that fits into the inner surface of 2′.
A locking protrusion 33 is formed on the inner peripheral side of the cylindrical portion 32 and protrudes inward. In addition, the cylindrical portion 32
A circular small hole 34 is provided at the center of the bottom surface of the holder.

In the state of FIG. 3A, the cap is fully fitted into the container 19'. In other words, the locking protrusion 2 formed on the cylindrical stopper 27 of the upper lid constituting the cap.
8 are fitted over the locking protrusion 33 provided on the cylindrical part 32 of the inner stopper 31 of the neck part 22' of the container 19', and the ring-shaped protrusion 26, which is the packing of the upper lid, is fitted onto the inner stopper 31. The cap is positioned in the correct closed position relative to the container 19'. In this state, the upper and lower inclined surfaces 10' and 11' of the flexible ring 9' are in contact with the outermost sides of the inclined surfaces 4' and 17' of the upper lid and lower frame 12' of the cap, and The lower stand 15' of the container 12' comes into contact with the upper surface 21' of the main body of the container 19'.

To remove the cap from the above condition, use the third
As shown in Figure B, press the flexible ring 9' inward with your fingers. At this time, the inclined surface 4' of the upper cover and the lower frame 1
The inclined surface 17' of the flexible ring 9' is wedge-shaped inward in cross-section, and since the upper cover is movable upward, the inclined surface 11' of the lower surface of the flexible ring 9' is downward. The frame 12' slides upwardly on the sloped surface 17', and the sloped surface 10' of the upper surface pushes the top cover upward along the sloped surface 4' of the top cover. This is the same as for the wedge shape when driving a wedge, but in this case, the lower frame 12' is attached to the upper surface of the main body of the container 19'.
Since the flexible ring 9' is protruded above the cover 1', by pressing the flexible ring 9' inward, the force with which the flexible ring 9' pushes the top cover upward becomes larger.

Therefore, the locking protrusion 28 of the cylindrical stopper 27 of the top lid passes over the locking protrusion 33 of the inner stopper 31, and the cap is removed from the container 19'. Furthermore, even if the cap is removed from the container 19', the retaining protrusion 8' of the claw piece 6' of the upper lid comes into contact with the retaining surface 16' of the lower frame 12'. There is no way to get out of '.

In the embodiment of the present invention described above, sloped surfaces are provided on the upper and lower inner circumferential surfaces of the flexible ring constituting the cap, the lower surface of the outer circumferential surface of the upper lid, and the upper surface of the outer circumferential portion of the lower frame, but the present invention is not limited to this. It is not something that is done, but
By making at least one of the surfaces in sliding contact with each other an inclined surface, the configuration can be configured such that when the flexible ring is pushed inward, a force that pushes the top cover upward is applied. Needless to say.

It goes without saying that the cap of the present invention can also be applied to a container having an inclined shoulder by providing an inclination to the bottom surface of the lower frame.

<<Effects of the invention>> The container with a cap according to this invention provides the following effects.

(1) The cap consists of a top lid that can be freely engaged and detached from the neck of the container, a bottom frame that comes into contact with the top surface of the main body of the container, and a cap that is sandwiched between the top lid and the bottom frame with at least one inclined surface interposed therebetween. The cap opening mechanism is made of a flexible ring, and the upper cover and the lower frame are provided with retaining means that allows relative movement of the upper cover with respect to the lower frame in the vertical direction and restricts them from coming off from each other. It can be configured built into the cap itself.

(2) Regarding the upward movement of the upper cover, since the upper cover is allowed to move relative to the lower frame, which serves as a reaction force receiver, by the retaining means, this movement can be carried out smoothly.

(3) The integrity of the upper cover, lower frame, and flexible ring can be maintained at all times by employing the above-mentioned retaining means.

(4) The cap can be opened simply by sliding the upper cover, lower frame, and flexible rings that make up the cap. Sliding friction, etc. that affect the opening operation of the cap can be set preferably, and a smooth opening operation of the cap can be ensured regardless of the material of the container.
