Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a container into which cosmetics such as lipstick can be dispensed.

[Conventional technology]

A container for storing stick-shaped cosmetics such as lipstick generally has an inner tube, an outer tube that is attached to the inner tube so that it can rotate freely and cannot be removed, and the cosmetic is attached to the tip, and the container slides into the inner tube. It is composed of a saucer body that is assembled freely but not mutually rotatable, and a gripping cylinder that is assembled and fixed to the lower end of the inner cylinder, and the saucer body is assembled by mutually rotating the inner cylinder and the outer cylinder. The container is moved up and down, forward and backward, and at the forward limit of the tray body, the cosmetic is protruded from the inner cylinder for use, and is stored and held by retreating into the inner cylinder.

Mutual rotation between the inner cylinder and the outer cylinder is specifically achieved by gripping the grip cylinder and the outer cylinder, and a threaded piece protruding from the saucer body is bored into the inner cylinder. The threaded piece passes through a vertical guide hole and is threaded into a threaded groove carved on the inner circumferential surface of the outer cylinder, and the threaded piece is guided by the mutual rotation of the inner and outer cylinders, allowing the saucer body to move up and down. It achieves backward movement.

[Problem that the invention attempts to solve]

By the way, for containers with this kind of configuration,
The structure of each member is complicated, and the assembly of each member requires time and effort such as positioning and alignment, and there is a problem that automatic assembly processing using a machine cannot be performed.

In other words, in conventional containers of this type, the inner cylinder is integrally formed with the gripping part, so the outer cylinder, which is attached to the inner cylinder in a mutually rotatable manner and cannot be removed, is attached to the inner cylinder. Since the inner cylinder is fitted and assembled from above, the guide hole must be formed into a vertical groove shape from the upper end in order to enable insertion and assembly of the outer cylinder. , and a locking flange is provided on the outer peripheral surface of the upper end of the inner cylinder to prevent the outer cylinder from slipping out from the inner cylinder.
In order to assemble the outer cylinder to the inner cylinder, it was necessary to elastically deform the upper end portion of the inner cylinder.

As described above, the upper end portion of the inner cylinder is extremely easily deformed due to the guide longitudinal groove, and when the outer cylinder is assembled to the inner cylinder, the inner cylinder must be elastically deformed. It is difficult to assemble the cylinder automatically using a machine, and the assembling operation has to be carried out manually by feeling the permissible elastic deformation of the inner cylinder with the tips of the fingers.

In addition, since the guide hole is molded to the top of the inner cylinder, the guide hole will be exposed at the top of the cylinder of the completed container, and this exposed guide hole will give an unpleasant appearance to the container. There were many times when I felt that way.

The present invention relates to a bar-shaped cosmetic dispensing container devised to solve the above-mentioned conventional problems, drawbacks, and inconveniences, and aims to facilitate assembly of each member.

[Means for solving problems]

The rod-shaped cosmetic dispensing container of the present invention has an inner cylindrical body 1
, an outer cylindrical body 5, a saucer body 10, and a grip body 14.

First, the inner cylindrical body 1 has a structure in which a locking collar 3 is provided around the outer circumference of the upper end of a cylindrical wall 2 having a linear cylindrical shape, and a longitudinal guide hole 4 is opened from the upper end to the lower end of the cylindrical wall 2. The outer cylindrical body 5 is externally assembled to the cylindrical wall 2 except for the lower part of the inner cylindrical body 1 described above so as to be mutually rotatable, and the inner circumferential surface of the peripheral wall 6 is provided with a screw groove 7,
A cylinder piece 8 is erected at the upper end of this peripheral wall 6,
A step portion 9 is formed on the inner circumferential surface of the upper portion and is engaged with the above-mentioned locking collar 3 from below.

A receiving tray body 10 for assembling and holding cosmetics is inserted into the inner cylinder body 1 so as to be slidable up and down, and the outer circumferential surface thereof is provided with a guide hole 4 of the inner cylinder body 1 passing through the guide hole 4 of the outer cylinder body 5. A threaded piece 12 that threads into the threaded groove 7 is provided in a protruding manner.

The gripping body 14 is a double cylinder with a bottom and has an outer wall 15 and an inner wall 16, and the lower part of the inner cylinder 1 is fitted and fixed between the outer wall 15 and the inner wall 16.
Further, an assembly cylinder 18 is formed at the upper end of the outer wall 15, the upper end surface of which contacts the lower end surface of the outer cylinder 5 assembled to the inner cylinder 1, and into which the outer cap 21 is externally assembled. .

The cylindrical piece 8 erected at the upper end of the outer cylindrical body 5 has a height equal to the height and width of the locking collar 3, so that the outer cylindrical body 5 stands up from the grip body 14 and has an exposed inner cylinder. This will cover the entire outer peripheral surface of the body 1.

Furthermore, the assembly tube 18 erected on the upper end of the outer wall 15 of the gripping body 14 is formed by extending the inner surface of the outer wall 15 upward, and its inner diameter is approximately the same as the inner diameter of the outer tube 5. The values are equal.

Therefore, by bringing the screwing piece 12 into contact with the upper end surface of the assembly tube 18, the lowering limit of the saucer body 10 is set, and the screwing piece 12 comes out of the screw groove 7. is now being prevented.

Therefore, the inner cylinder 1 is integrally combined with the gripper 14, and by mutually rotating the outer cylinder 5 and the gripper 14, the inner cylinder 1 and the outer cylinder 5 can be rotated relative to each other. This mutual rotation causes the screwing piece 12 to be guided by the guide vertical hole 4 and the screw groove 7, and the saucer body 10 to slide up and down within the inner cylinder body 1.

Further, the upper end of the outer cylinder 5 has a step portion 9 and a locking collar 3.
The lower end of the assembly cylinder 18 of the grip body 14 is
By coming into contact with the upper end, the outer cap 21 is reliably prevented from coming off, and furthermore, since the outer cap 21 is externally assembled to the assembly cylinder 18, the inner cylinder body 1 and the outer cylinder body 5 can be mutually rotated when not in use. There is no risk of movement, and the so-called phenomenon of the cosmetics sticking to the top does not occur.

[Effect]

In the above-described configuration, each member is assembled in the following manner.

That is, hold the locking collar 3 portion which is the upper end of the inner cylinder 1, fit the outer cylinder 5 from the lower end of the inner cylinder 1, insert the saucer body 10 into the inner cylinder 1, and tighten the screws. The mating piece 12 is engaged with the guide vertical hole 4 and the screw groove 7, and the lower part of the inner cylinder body 1 is connected to the outer wall 15 of the grip body 14 and the inner wall 1.
It is fitted and fixed between 6 and 6.

In this case, the outer circumferential body 5 is externally fitted and assembled from above to the inner cylinder 1 held in an inverted state, and then the inner cylinder 1, that is, the upper end opening of the upright inner cylinder 1, insert the saucer body 10 until its threaded piece 12 fits into the guide vertical hole 4 and abuts against the lower end surface of the outer cylinder 5. Assemble.

When the threaded piece 12 abuts against the lower end surface of the outer peripheral body 5, the outer cylinder 5 is rotated relative to the inner cylinder 1 while applying a slight pressing force to the saucer body 10. By doing so, the screwing piece 12 is screwed into the screw groove 7, and the inner cylinder body 1, the outer cylinder body 5, and the saucer body 10 are assembled.

Once the threaded engagement piece 12 of the saucer body 10 has been threaded into the threaded groove 7, the gripping body is held against this combination of the inverted inner cylinder body 1, outer cylinder body 5, and saucer body 10. 1
4 from above, the lower end portion of the inner cylinder 1 is firmly fitted between the outer wall 15 and the inner wall 16 of the gripper 14, and the assembly of the container body is completed.

In the above-described assembly operation, the outer cylinder body 5, the saucer body 10, and the grip body 14 are sequentially assembled to the inner cylinder body 1 held in an inverted position, and the assembly is simply a fitting assembly. Therefore, each assembly operation is extremely simple, and automatic assembly by a machine can therefore be carried out easily.

Further, since the upper end of the guide vertical hole 4 in the inner cylinder body 1 is closed, the saucer body 10 that has moved upward cannot escape from inside the inner cylinder body 1. There is no need to provide the inner cylinder 1 with a special structure for preventing it from slipping out, and the structure of the inner cylinder 1 can be made that much simpler.

Further, the lower end portion of the inner cylinder 1, whose mechanical strength is reduced by forming the guide vertical hole 4, is firmly fitted between the outer wall 15 and the inner wall 16 of the gripping body 14. Since it is assembled and held by this gripping body 14, there is no problem of lack of mechanical strength due to the presence of this guide vertical hole 4 when it is assembled into a container, and it is held by the receiving tray body 10. Inner cylindrical body 1 which is an entrance/exit for cosmetics
Since the upper end has a complete ring shape with a locking flange 3 attached, it can exhibit sufficient strength, and the assembled container thereby has sufficient mechanical strength.

Since the guide hole 4 does not extend to the upper end of the inner cylindrical body 1, the guide hole 4 is not exposed to a large extent at the upper end of the container body. It is possible to eliminate the unsightly appearance of the container body.

〔Example〕

In the case of the illustrated embodiment, the locking collar 3 is formed with a large height and width, and the mechanical strength of the upper end of the inner cylindrical body 1 forming the guide vertical hole 4 from directly below the locking collar 3 is increased. We're trying to make it as big as possible.

In this way, the mechanical strength of the upper end of the inner cylinder 1 is increased by increasing the height width of the locking collar 3 as much as possible to increase the mechanical strength of the upper end of the inner cylinder 1. This is to improve the safety of the cylindrical body 1 and to facilitate its handling.

The saucer body 10 has a bottom portion 13 with a through hole formed in the center.
and a short cylindrical wall 11 having an outer diameter equal to the inner diameter of the inner cylinder 1. A pair of protrusions are provided.

Further, it goes without saying that the inner surface of the receiving tray body 10 is provided with protrusions or recesses in order to more strongly and stably hold the rod-shaped cosmetic.

The gripping body 14 has an outer wall 15 and an inner wall 16 that are integrally erected coaxially on the upper surface of a bottom wall 17 that has a through hole in the center, and a space between the outer wall 15 and the inner wall 16 that are coaxially arranged. The interval formed between the outer wall 15 and the inner wall 16 is formed to be slightly larger than the wall thickness of the cylindrical wall 2 of the inner cylindrical body 1. A large number of longitudinal assembly strips 20 having a protruding height slightly larger than the difference in wall thickness of the cylindrical wall 2 are provided over substantially the entire height range of the outer wall 15.

In this way, the wall thickness of the cylindrical wall 2 is increased to increase the distance between the outer wall 15 and the inner wall 16, and a large number of assembly strips 20 are used instead.
The reason why the inner circumferential surface of the outer wall 15 is shaped is that it facilitates fitting and assembling the lower end of the inner cylindrical body 1 between the outer wall 15 and the inner wall 16, and that this assembling is facilitated by the assembly strip 20.
This is to ensure that it is held firmly by its elasticity.

Furthermore, the assembly tube 18 erected from the upper end of the outer wall 15 has an outer diameter smaller than that of the outer cap 2 than the outer wall 15.
By setting the wall thickness to be smaller by the wall thickness of I try to set limits.

The cylindrical piece 8 in the outer cylindrical body 5 is formed with an inner diameter larger than the inner diameter of the peripheral wall 6, which has a threaded groove 7 on its inner peripheral surface, by a value equal to the depth and width of the threaded groove 7. The shaping of the grooves 7 is now easier to achieve.

[Effect of idea]

As is clear from the above description, the container for dispensing bar-shaped cosmetics according to the present invention is easy to mold because the structure of each component is simple, and the mutual assembly of each component is a simple fitting assembly. At the same time, the assembly operation is extremely simple because it can be achieved by fitting and assembling from a single direction, and therefore automatic assembly using a machine can be easily carried out, and in the assembled state The lower end of the inner cylinder, which has the weakest mechanical strength, is firmly held by the gripping body, allowing it to maintain a stable shape.Furthermore, since the guide hole is not exposed to a large extent, the deterioration of the appearance due to the guide hole is greatly reduced. It exhibits many excellent effects such as being able to reduce the amount of water used.
