Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a cap device that is assembled into a container body such as a bottle container or a tube container, and more specifically, it relates to a cap device that can be opened and closed with a single touch. The purpose is to

[Conventional technology]

Screw caps have generally been used as opening/closing cap devices attached to the mouthpiece of containers such as bottles and tube containers, or screw caps are screwed onto and removed from the mouthpiece of the container body. Therefore, in order to attach and detach the screw cap, it is necessary to rotate the screw cap by more than one rotation relative to the opening of the container body, which has resulted in the dissatisfaction that opening and closing operations are troublesome.

[Problem that the invention seeks to solve]

In order to solve this dissatisfaction, various cap devices have been produced in the past, but each of them has caused some kind of dissatisfaction.

For example, a cap device consisting of an assembly part and a rotating stopper part, which is opened and closed by the rotating action of the turnable stopper part, has been relatively popular. It can only be used as a containment container and has a relatively complex structure.
In addition, since high sealing performance is required for the sliding parts, it is necessary to mold them with high molding accuracy, which results in a high incidence of defective products, and furthermore, the sealing performance deteriorates as the number of uses increases. There were shortcomings and complaints.

In addition, in the case of a cap device that uses a hinge mechanism and an engagement mechanism, in order to open the cap, it is necessary to hook the fingertip on the lid body and release a relatively large engagement, so the opening operation requires a large amount of effort. requires power,
In addition, since the fingertips are directly hooked on the lid, the portion where the fingertips are hooked tends to become dirty, resulting in dissatisfaction and drawbacks such as being unhygienic.

[Means for solving problems]

The present invention was devised in order to eliminate the drawbacks and dissatisfaction in the conventional examples described above, and includes a cap device that includes an assembly body that is a part that is attached to a container body;
It is composed of a lid body that opens and closes the spout formed in the assembled body, and the engagement portion between the assembled body and the lid body when the spout is closed, and the lid body that rides on the assembled body. By elastically deforming the assembled body, the fixed height positional relationship with the lid part is changed, and the lid body can be moved with one touch without touching the lid body. The structure is such that it can be opened and closed.

Hereinafter, a cap device according to the present invention will be explained with reference to the drawings showing one embodiment thereof.

The cap device 1 according to the present invention has an outer cylindrical body 4 which is a part to which a fingertip force is applied from the outer peripheral edge of the lower surface of the top plate 5, which has a donut flat disk shape by opening a spout 9' in the center. Then, assembling inner cylinder pieces 3 that provide a part for assembling the container body 15 to the spout 16 from the inner circumferential end of the lower surface of the top plate 5 are respectively provided hanging down, and near the outer circumferential edge of the upper surface of the top plate 5 are attached. Stopper 7
An assembled body 2 made of thermoplastic synthetic resin capable of elastic deformation, comprising a pair of protruding locking bodies 6 erected in opposing positions with the spout 9' narrowed in position.
In this state, a peripheral wall 12 is suspended from the disk-shaped top wall 11 and the outer peripheral end of the lower surface, and the lower end of the peripheral wall 12 is in contact with the mounting peripheral end surface 8, which is the outer peripheral end of the upper surface of the top plate 5. A lid body 1 is provided with a locking protrusion 13 that climbs over the locking piece 7 and locks from below.
0, and a hinge body 14 that hinges the assembled body 2 and the lid body 10 together.

The assembled body 2 includes a cap device 1 attached to a container body 15.
This is a part for assembling and fixing, and the assembling of the assembled body 2 to the mouth pipe 16 of the container body 15 is achieved by the assembled inner cylinder piece 3.

The outer cylindrical body 4, which surrounds the assembled inner cylinder piece 3 and is provided with a gap of a sufficiently large width between it and the assembled inner cylinder piece 3, is capable of applying an external force to open the lid body 10. It is designed so that when the top plate 5 is deformed by the action of an external force, the internal stress caused by this deformation is sufficiently applied to the top plate 5.

That is, the top plate 5 has a donut-like flat disk shape.
The wall thickness etc. are set so that when the outer cylinder piece 4 is deformed in the direction of being flattened by a fingertip, it easily deforms into a saddle shape according to the deformation of the outer cylinder piece 4. be.

A pair of locking bodies 6 erected near the outer periphery of the upper surface of the top plate 5 on which the assembled inner cylinder piece 3 and outer cylinder piece 4 are suspended are locking bodies 6 for locking and holding the lid body 10 on the top plate 5. Although it has a stopper 7, its height is not a large value, but is basically set to a small value when molded.

When the peripheral wall 12 of the lid body 10 is in its "closed" state, its entire lower end surface is in contact with the mounting peripheral end surface 8 of the top plate 5, so that the slight deformation of the top plate 5 causes , it is possible to receive a push-up force from this top plate 5.

[Effect]

Since the cap device 1 according to the present invention has the above-described structure, in the "closed" state shown in FIG. 1, a crushing force is applied to the outer cylinder piece 4 as shown by the arrow in FIG. When the outer cylinder piece 4 is deformed into a flat shape by the deformation of the outer cylinder piece 4,
As shown in FIGS. 3 and 4, the top plate 5 has a portion of the mounting circumferential end surface 8 located in the direction in which the crushing force was applied, which is displaced downward, and a center angle of 90° is shifted from this portion. The portion of the riding circumferential end surface 8 that is located is deformed into a substantially saddle shape that is upwardly displaced.

Due to this deformation of the top plate 5, on the assembled body 2,
The lid 10, which was positioned with the entire lower end surface of the peripheral wall 12 in contact with the mounting peripheral wall surface 8, receives a pushing force from the upwardly displaced top plate 5, and is forced to open. The state will be changed.

That is, when the outer cylinder 4 is deformed into a flattened form, the top plate 5 is deformed into a shape resembling a saddle shape due to this deformation, and the portion of the mounting peripheral end surface 8 that is upwardly displaced due to the deformation of the top plate 5 deforms. The lid 10 is then pushed up, and the lid 10 is switched from the "closed" state to the "open" state.

〔Example〕

In the case of the illustrated embodiment, a thread is cut into the inner circumferential surface of the assembled inner cylinder piece 3, and it is configured to be assembled by screwing into a mouthpiece 16 having a thread cut into the outer circumference.

The inner diameter of this assembled inner cylindrical piece 3 is set to a value slightly larger than the diameter of the spout 9'. The inner circumferential end portion is a portion that is positioned in close contact with the upper end surface of the mouth tube 16.

The locking body 6 is formed into a short cylindrical shape, and locking pieces 7 are attached in the form of horizontal protrusions at the upper end portions of the outer peripheral surface of the portions located on both front and rear sides of the short cylindrical locking body 6. There is.

A spout tube piece 9 stands up from the upper surface of the inner circumferential end of the top plate 5 on which a spout 9' is formed, and forms a spout passage for the contents stored in the container body 15, and also serves as a lid. This makes it easy to achieve a hermetic seal of 10.

The locking protrusion 13 provided on the lid body 10 is connected to the peripheral wall 12.
It is formed in the shape of a circumferential protrusion on the inner peripheral surface.

The hinge body 14 is integrally connected and molded between the rear upper end of the assembled body 2 and the rear upper end of the lid body 10, but this hinge body 14 always exerts its elasticity in the "open" direction. Advantageously, it is configured to allow

In this illustrated embodiment, as shown in FIG.
When the lid body 10 is in the “closed” state with the locking protrusion 13 locked to the locking piece 7 from below, the opening upper end surface of the spouting tube piece 9 is on the lower surface of the top wall 11 all around. Since they are in close contact, the container body 15 is kept hermetically sealed by the lid body 10.

Now, from the "closed" state shown in FIG. 1, crushing force is applied to the outer cylinder piece 4 from both sides as shown by the arrows in FIG. When the outer cylindrical piece 4 is deformed to the closed position, the top plate 5 upwardly displaces the mounting circumferential end surfaces 8 located before and after it (see Fig. 3), and the mounting circumferences located on both sides thereof. Downward displacement of 8 parts of the end face (see Figure 4)
The lid body 10 is then deformed almost into a saddle shape, and the lid body 10 is pushed up by the front and rear portions of the mounting circumferential end surface 8 that is displaced upward.

At this time, the top plate 5 undergoes a curved deformation with its both ends raised in the front-rear direction, so that the upper ends of both the locking bodies 6, on which the locking pieces 7 are provided, are tilted in a direction toward each other. As a result, the engagement between the locking piece 7 and the locking protrusion 13 becomes extremely weak, or the locking between the locking piece 7 and the locking protrusion 13 is completely released.

Therefore, when the hinge body 14 is given elasticity to rotate the lid body 10 in the "open" direction, the lid body can be moved by crushing and deforming the outer cylinder piece 4 from both sides. 10 is lifted up from above the assembled body 2 by the elasticity of the hinge 14, and then the container body 1
5 releases will be achieved.

Separately from FIGS. 3 and 4, an external force is applied to the outer cylinder piece 4 from the front and rear directions, that is, from the side where both locking pieces 7 are provided, as shown in FIGS. 5 and 6. As shown, when the outer cylinder piece 4 is elastically deformed,
Due to this deformation of the outer cylinder piece 4, the front and rear portions of the mounting circumferential end surface 8 are displaced downward, and both side portions of the mounting circumferential end surface 8 are upwardly displaced, and the mounting circumferential wall surface 8 is displaced upwardly.
Both side portions act on the lid body 10 with a pushing force.

However, as is clear from FIG. 5, due to the downward deformation of the front and rear portions of the mounting circumferential end surface 8, both the locking bodies 6 move in the direction away from each other from the upper ends where the locking pieces are protruded.
That is, since they are inclined outward, the locking force between the locking pieces 7 and the locking protrusions 13 is strengthened.

Therefore, in order to open the lid 10 by the crushing force from the side where both the locking pieces 7 are provided, rather than increasing the engagement force between the locking pieces 7 and the locking protrusion 13,
It is necessary that the pushing up force against the lid body 10 by the mounting circumferential end surface 8 is increased much more strongly and rapidly.

For this purpose, the height of the position where the locking piece 7 is attached to the locking body 6 is made sufficiently low, and the locking body 6 is
However, even if the locking member 6 is tilted in the direction shown in FIG. 5, it is sufficient to prevent the locking piece 7 from being significantly displaced outwardly due to the tilting displacement of the locking body 6.

That is, the attachment position and height of the locking piece 7 are low;
If the amount of outward displacement of the locking piece 7 when the locking body 6 is tilted is set small, the amount of upward displacement of the mounting peripheral end surface 8 portion of the locking piece 7 will be smaller. The increasing strength speed of the displacement becomes much smaller, and as a result, before the locking force between the locking piece 7 and the locking protrusion 13 becomes sufficiently large, the amount of displacement increases from the mounting peripheral end surface 8 to the lid body 10. The pushing up force that acts is much larger than the locking force between the locking piece 7 and the locking protrusion 13, and the locking between the locking piece 7 and the locking protrusion 13 is forcibly released. to open the lid body 10.

At this time, the lid body 10 has the locking piece 7 and the locking protrusion 13.
At the same time as the lock is released, the push-up force from the mounting circumferential end surface 8 causes a vigorous opening rotation.

In order to turn the open lid 10 into a closed state, it is sufficient to simply press the lid 10 from above against the assembled body 2, thereby locking the locking protrusion 13 and the locking piece 7. .

In addition, in the case of the illustrated embodiment, the locking piece 7 is the locking body 6.
Although the locking protrusion 13 is provided protruding from the outer periphery of the locking body 6, it may also be provided on the inner periphery of the locking body 6. Also, the locking protrusion 13 is not provided on the peripheral wall 12, but may be provided independently hanging from the top wall 11. It is a good idea to set it up.

Furthermore, it goes without saying that the hinge body 14 is not limited to one using a hinge piece, and may have a butterfly plate structure.

〔Effect of the invention〕

As is clear from the above description, in the cap device according to the present invention, the lid can be opened by a one-touch operation on the assembled body. There is no risk of inconveniences such as contaminating the lid body, and since the spout formed in the assembled body can be opened as is, the contents that can be stored in the container body are not limited. It can be applied to both liquids and powders, has a simple structure, is easy to manufacture, and can be opened and closed with a simple one-touch operation, making it easy to use and exhibits many excellent effects.
