Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a synthetic resin positioning cap that can be attached to and detached from a bottle with a single touch. Its purpose is to prevent the decline.

[Prior Art] As a cap that is attached to a bottle whose body part is in the shape of a rectangular tube, attachment and detachment from the bottle can be achieved with one touch using an undercut mechanism, and the upper surface of the shoulder of the bottle can be attached and removed with one touch. The cap has a tapered surface structure, and the inclination of the tapered surface is used to achieve alignment of the assembled cap with respect to the bottle, and the cap is detached from the bottle by a simple rotational movement. There is something.

The specific structure of the above-mentioned conventional example is that a bottle is provided with a locking strip on the outer circumferential surface of the mouthpiece, and the cap part that is crowned with the mouthpiece is engaged by going over the locking strip. A bullet wall piece having a locking protrusion on its inner peripheral surface is formed into a tongue shape, and by utilizing the elastic deformation of this bullet wall piece, it is possible to cross over and cross over the locking shape of the locking protrusion. The lock is released, and the locking protrusion is kept locked to the locking strip.

[Problem that the invention attempts to solve]

This positioning cap described above has the excellent advantage of being easy to handle, but it also allows the assembled posture of the cap, which seals the bottle, to be adjusted to the bottle using only the elasticity of the bullet wall piece. This requires a relatively strong elasticity for this bullet wall piece, and on the other hand, the opening of the bottle is achieved against the elasticity of this bullet wall piece.
The stronger the elasticity of this bullet wall piece, the more difficult it becomes to open and close the bottle.

For this reason, it is impossible to make the elasticity of the bullet wall piece extremely strong, so when the bottle is closed,
The bullet wall piece is in a state in which elasticity is applied in the direction of maintaining the locking of the locking projection piece to the locking strip, and the elasticity of the bullet wall piece is effective for retaining the cap assembled to the bottle body. This makes it possible to make it work.

In this way, as long as the cap holds the bottle closed, the bullet wall piece is in a deformed state that exerts its elasticity, causing premature deformation due to material fatigue. This causes a serious inconvenience in that the cap cannot exert an effective assembly holding force against the bottle body.

In other words, the synthetic resin material used to form the cap for opening and closing the bottle does not have sufficient physical properties to exhibit the elasticity required for the bullet wall piece in the cap over a long period of time. This type of cap either lacks the ability to maintain the closed state or loses its ability to maintain the closed state at an early stage.

As a means of resolving the lack of elasticity of the bullet wall piece that is integrally molded into the synthetic resin cap body, only this bullet wall piece is molded separately from an elastic material with excellent elasticity, and the bullet wall piece made of this elastic material is It is conceivable that the bullet wall piece be assembled into the cap body, but if only the bullet wall piece is made a separate piece, not only will it be troublesome to assemble the bullet wall piece to the cap body, but the bullet wall piece, which is a separate piece, will be difficult to assemble. The structure of the cap body for assembly becomes complicated, which unnecessarily increases the manufacturing cost of the cap body.

The present invention was devised to solve the above-mentioned problems in the conventional example, and the bullet wall piece is integrally molded with the main body of the cap, and the elasticity exerted by the bullet wall piece is appropriately improved. The technical challenge is to make this possible.

[Means for solving problems]

The means of the present invention includes a locking strip 5 on the outer peripheral surface of the upper end of the body 2 in the shape of a rectangular cylinder with a bottom.
It is assembled to the mouthpiece 4 of a bottle body 1 (see Fig. 1), which is constructed by connecting a short cylindrical mouthpiece 4 with a protrusion and a pyramidal cylinder-shaped top plate 3 standing upright from the center. The positioning cap 9 (see FIG. 1) whose lower end comes into contact with the tapered inclined surface of the top plate 3 and is pushed up to separate from the mouth tube 4 when rotated in any direction;
An inner cylinder wall 1 having a short cylindrical shape with a crown and covering a mouth cylinder 4
1 (See Figures 2, 3, 4 and 7)
A short cylindrical outer cylinder wall 12 (second
, 3, 4 and 7), and the inner cylinder wall 1 facing the corner of the outer cylinder wall 12.
It has a bullet wall piece 15 formed into a tongue shape by providing a notch 14 in one part (see FIGS. 3 and 7), and is provided protrudingly on the inner circumferential surface of the bullet wall piece 15 for locking. The bullet wall piece 15 has a locking protrusion 16 (see FIGS. 3 and 7) that crosses over the strip 5 and locks from below. 15 and the outer cylinder wall 12 (see FIGS. 2 and 7).

[Effect]

The inner cylinder wall 11 and the outer cylinder wall 12 constitute an integrally molded double cylinder structure, but the inner cylinder wall 1 on the inside
1 has a cylindrical shape, while the outer outer cylinder wall 12
Since it has a rectangular tube shape, a gap is formed at the corner of the outer tube wall 12 at least between the inner tube wall 11 and the outer tube wall 12. The cushion material 17 is
It is inserted into the gap inevitably formed between the inner cylinder wall 11 and the outer cylinder wall 12, and therefore a cut is made in the part of the inner cylinder wall 11 opposite to the corner of the outer cylinder wall 12. It is located opposite to the bullet wall piece 15 formed by forming the notch 14 .

This cushion material 17 has its elasticity
5, the bullet wall piece 15 acts inwardly to press it inward, so that when the bottle 1 is in the closed state, the bullet wall piece 15 is pressed toward the outer peripheral surface of the mouthpiece 4. Therefore, the locking force of the locking protrusion 16 with respect to the locking strip 5 is increased.

Further, the cushion material 17 is made of an elastic material completely different from the synthetic resin material from which the cap 9 is molded, and is capable of stably retaining the locking protrusion 16 against the locking strip 5. Locking protrusion 1
When the locking protrusion 6 gets over the locking strip 5, the locking strip 5 of the locking protrusion 16 Even though the locking and holding force against the bottle body 1 is increased, it is possible to obtain a form of elasticity that makes it easy to attach and detach the cap 9 to the bottle body 1.

Furthermore, the cushion material 17 is inserted between a corner of the outer cylinder wall 12 and a bullet wall piece 15 that is a part of the inner cylinder wall 11; Due to the difference in shape between the outer cylinder wall 12 and the inner cylinder wall 11, the space between the bullet wall piece 15 is a space that is almost closed around it, and therefore the cushion material inserted and assembled into this space is 17, without requiring special assembly means and positioning means,
It is assembled and held almost precisely and immovably within this space.

〔Example〕

A bottle body 1 made of a hard material such as glass has a body 2 in the shape of a regular square cylinder, and a top plate 3 has a sloped surface 8 that is tilted upward with its top facing toward the center.
Therefore, there is a fuselage 2 at the connection part of each inclined surface 8.
A ridge line 7 is formed that slopes upward from each corner toward the mouth pipe 2. Further, a flat peripheral surface 6 is formed at the upper peripheral end of the top plate 3, and when the cap 9 is assembled to the bottle body 1, the lower end surface of the cap 9 forms a part on which the cap is placed. ing.

The cap 9 includes an inner cap 10 constituting the main part and an outer cap 30 provided as an outer shell.
The outer cap 30 is simply assembled to the inner cap 10.

The middle cap 10 has a structure in which an inner cylinder wall 11 and an outer cylinder wall 12 in the shape of a short rectangular cylinder, which is one size smaller than the body 2, are connected between their lower ends by a bottom wall 13.

A notch 1 is cut and formed to form a bullet wall piece 15 in a portion of the inner cylinder wall 11 facing a corner of the outer cylinder wall 12.
4 has a sharp U-shape, and therefore the molded bullet wall piece 15 is in the shape of a tongue piece in a hanging position.

A hole 19 for assembly is formed in the top plate 18 that closes the upper end of the inner cylinder wall 11, and a protrusion 20 is provided around the lower end of the opening surface of the hole 19. There is.

As shown in FIG. 7, a packing material 21 made of a soft synthetic resin material is assembled into this hole 19, and the packing material 21 is attached to the inner cylinder wall 11 at the center of the packing material 21. This is achieved by forcibly fitting and assembling the crested short cylindrical portion 22 protruding into the hole 19 from below, and from the lower end peripheral end of the crested short cylindrical portion 22 to the outer peripheral end, the outer peripheral wall 24
By providing a groove 25 on the upper surface thereof, a flange portion 23 is provided around the cap 9. When the cap 9 is assembled to the spout 4, this flange portion 23 is formed on the upper end surface of the spout 4. 23 is facing. Groove 25
A cushion ring 26 is arranged inside so that the packing action of the packing material 21 can be more effectively exerted. 22 into the hole 19 is stably maintained.
A locking strip 27 is provided around the 0 to lock from above.

The outer cylindrical wall 12 has a much smaller height than the inner cylindrical wall 11, and merely forms an assembly holding part for the cushion material 17, and also serves as an attachment part for the inner cap 1.
The outer cap 30 forms an assembly part for the outer cap 30.

That is, the outer cap 30 has a circumferential wall 31 having a rectangular cylindrical shape that is approximately the same as the body 2, and is assembled to the inner cap 10 by fitting the lower end portion of the circumferential wall 31 to the outer cylindrical wall 12. There is. A presser rib 33 is provided at the corner of the peripheral wall 31 of the outer cap 30 in a form that hangs down from the top plate 32. However, this is to prevent unauthorized escape upward from the storage space of the inner cap 10.

To assemble the outer cap 30 to the inner cap 10, first insert a protrusion 35 into the lower end of the inner surface of the peripheral wall 31 of the outer cap 30 to engage the undercut strip 28 provided on the lower part of the outer surface of the outer cylinder wall 12. vertical strips 3 that engage with a plurality of vertical grooves 29 provided on the upper part of the outer peripheral surface of the inner cylinder wall 11 to maintain a constant assembled attitude of the outer cap 30 with respect to the inner cap 10;
A protrusion 4 is provided on the upper end of the inner peripheral surface of the peripheral wall 31.

[Effect of idea]

As is clear from the above explanation, the present invention is designed to apply appropriate elasticity of the cushion material assembled to the cap to the bullet wall piece integrally formed on the cap, which achieves attachment and detachment of the cap to the bottle body. Therefore, the function of keeping the cap in the closed state by the bullet wall piece can be well and stably maintained over a long period of time, and the cap can be smoothly attached and detached from the bottle body. Since the cushion material is placed at the inner corner of the rectangular tube-shaped outer cylinder wall, it is possible to stably attach the cushion material to the cap without requiring a special structure for attaching the cushion material. It exhibits many excellent effects such as being able to achieve and maintain the condition.
