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 all the way 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.

Furthermore, in the case of inner cylinders and saucers, their vertical relationships can be easily and accurately determined visually and mechanically based on their appearance and external structure. Although it is possible to accurately judge the vertical relationship and align the trays in a set posture, the vertical positioning is difficult because the upper end of the spiral groove carved into the inner circumferential surface has a structural part that prevents the tray body from slipping out. Since the necessary external cylinder has a simple cylindrical appearance, it is extremely difficult to visually and mechanically determine its vertical relationship.For this reason, automatic assembly using a machine is difficult. This is completely impossible, and has been a major obstacle to automatic assembly of this type of dispensing container.

The present invention relates to a bar-shaped cosmetic dispensing container devised to solve the above-mentioned conventional problems, drawbacks, and inconveniences, and an object of the present invention is 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 8 , and a grip body 12 .

First, the inner cylindrical body 1 has a structure in which a locking collar 3 is provided on the outer periphery of the upper end of a linear cylindrical wall 2, 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 has the above-described locking collar 3 on the cylindrical wall 2 except for the lower part of the inner cylindrical body 1, and has an upper end surface.
They are externally assembled so that they can rotate freely relative to each other in a position where they abut and lock against the lower surface from below, and a screw groove 7 is carved on the inner peripheral surface of the peripheral wall 6 over the entire length.

The tray body 8 for assembling and holding cosmetics is connected to the inner cylindrical body 1.
It is inserted into the interior so that it can slide up and down, and on its outer surface,
A threaded engagement piece 13 is provided to protrude through the guide vertical hole 4 of the inner tubular body 1 and threaded into the threaded groove 7 of the outer tubular body 5.

The gripping body 12 is a double cylinder with a bottom and has an outer wall 13 and an inner wall 14.
The lower part of the inner cylindrical body 1 is fitted and fixed between the inner cylindrical body 1 and the outer cap. 1
An assembly cylinder 16 is formed in which the assembly 9 is externally assembled.

The assembly tube 16 erected on the upper end of the outer wall 13 of the gripping body 12 is formed by extending the inner circumferential surface of the outer wall 13 upward, and its inner diameter is the same as the inner diameter of the outer tube 5. The values are almost equal.

Therefore, by bringing the screwing piece 10 of the saucer body 8 into contact with the upper end surface of the assembly tube 16,
The lowering limit is set, and the screwing piece 10 is prevented from slipping out from the screw groove 7.

Therefore, the inner cylinder 1 is integrally combined with the gripper 12, and by mutually rotating the outer cylinder 5 and the gripper 12, the inner cylinder 1 and the outer cylinder 5 can be rotated relative to each other. This mutual rotation causes the screwing piece 10 to be guided by the vertical guide hole 4 and the screw groove 7, and the saucer body 8 to slide up and down within the inner cylinder body 1.

Further, the upper end of the outer cylinder body 5 is locked to the locking collar 3,
Since the lower end of the gripper 12 comes into contact with the upper end of the assembly cylinder 16, it is reliably prevented from coming off.Furthermore, since the outer cap 19 is externally assembled to the assembly cylinder 16, the inner cylinder can be removed when not in use. 1 and the outer cylindrical body 5 do not rotate relative to each other, and the so-called top sticking phenomenon of cosmetics does not occur.

[Effect]

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

That is, hold the locking flange 3 portion at 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 8 into the inner cylinder 1, and tighten the screws. The mating piece 10 is engaged with the guide vertical hole 4 and the threaded groove 7, and the lower part of the inner cylinder body 1 is connected to the outer wall 13 and inner wall 14 of the grip body 12.
It is fitted and fixed between the two.

The outer cap 19 is externally assembled to the assembly cylinder 16 of the gripping body 12, and its upper end abuts the lower end of the outer cylinder 5 assembled to the inner cylinder 1.

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 inverted inner cylinder 1, insert the saucer body 8 until its threaded piece 10 fits into the guide vertical hole 4 and abuts against the lower end surface of the outer cylinder 5. Assemble.

When the screwing piece 10 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 8, and held. By doing so, the screwing piece 10 is screwed into the screw groove 7, and the inner cylinder 1, the outer cylinder 5, and the saucer body 8 are assembled.

Once the screwing piece 10 of the saucer body 8 has been screwed into the screw groove 7, the inner cylinder 1 and the outer cylinder 5 are turned upside down.
Push the gripper 12 from above into the combination of the inner cylindrical body 1 and the saucer body 8,
The outer wall 13 and inner wall 14 of No. 2 are firmly fitted to complete the assembly of the container body.

In the above-mentioned assembly operation, it is sufficient to sequentially assemble the outer cylinder body 5, the saucer body 8, and the grip body 12 to the inner cylinder body 1 held in an inverted position, and the assembly is simply a fitting assembly. Since each assembly operation is simple, automatic assembly by a machine can be easily performed.

Further, since the upper end of the guide vertical hole 4 in the inner cylinder body 1 is closed, the saucer body 8 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.

Furthermore, 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 13 and the inner wall 14 of the gripping body 12. Since it is assembled and held by this gripping body 12, 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 also held by the receiving tray body 8. The upper end of the inner cylindrical body 1, which is the entrance and exit for the cosmetics, has a complete ring shape with a locking flange 3, so it can exhibit sufficient strength. The container 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.

In particular, the outer cylindrical body 5 has a simple linear cylindrical shape and has no structural vertical relationship, so there is no need to consider its vertical position when assembling it into the inner cylindrical body 1, so it is automatically mechanized. Assembling work becomes even smoother.

In addition, in the case of the assembled container main body, the outer circumferential surface of the locking collar 3 of the inner cylinder 1 is exposed in a circumferential band shape on the outer cylinder 5, but the color of the inner cylinder 1 is different from that of the outer cylinder. body 5
By setting the color to be different from the color of the container, a band-like pattern of a different color is formed circumferentially at the upper end of the container body, which makes the appearance of the container body more varied and good. Furthermore, if the upper end portion of the outer cap 19 assembled to the locking collar 3 is configured to fit lightly, the assembly of the outer cap 19 to the container body can be made extremely stable. be able to.

〔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 reason why the height and width of the locking collar 3 is made as large as possible to increase the mechanical strength of the upper end of the inner cylinder 1 is that the inner cylinder is used when handling the inner cylinder 1 alone. This is to increase the safety of the body 1 and to facilitate its handling.

The saucer body 8 has a bottom portion 11 with a through hole formed in the center.
and a short cylindrical wall portion 9 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 tray body 8 is provided with protrusions or recesses in order to more strongly and stably hold the rod-shaped cosmetic.

The gripping body 12 has an outer wall 13 and an inner wall 14 that are integrally erected coaxially on the upper surface of a bottom wall 15 that has a through hole in the center. The interval formed between the outer wall 13 and the inner wall 14 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 vertical assembly strips 18 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 13.

In this way, the distance between the outer wall 13 and the inner wall 14 is increased by increasing the wall thickness of the cylindrical wall 2, and instead, a large number of assembly strips 18
The reason why this is shaped on the inner circumferential surface of the outer wall 13 is that it facilitates fitting and assembling the lower end of the inner cylinder 1 between the outer wall 13 and the inner wall 14, and also that this assembling reduces the elasticity of the assembling strip 18. This is to ensure that it is held more firmly.

Furthermore, the assembly cylinder 16 erected from the upper end of the outer wall 13 has an outer diameter smaller than that of the outer cap 1 than the outer wall 13.
By setting the outer cap 19 to be smaller by the wall thickness of the cap 9, a step 17 is formed on the outer peripheral surface of the proximal end connected to the outer wall 13, and this step 17 makes it easier to assemble the outer cap 19 to the gripper 12. I try to set limits.

The locking collar 3 of the inner cylinder 1 is formed to have a protruding height equal to the thickness of the peripheral wall 6 of the outer cylinder 5, so that the outer peripheral surface of the locking collar 3 and the outer peripheral surface of the outer cylinder 5 are However, the protruding height of the locking flange 3 is made larger than the wall thickness of the peripheral wall 6, so that the locking flange 3 protrudes outward from the upper end of the container body. By doing so, the assembly of the outer cap 19 to the container body can be stabilized, and the outer cap 19 can be easily attached and detached.

[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. In addition, it is possible to apply a new color decoration by using the locking flange exposed at the upper end of the outer circumferential surface of the container body, and to improve the assembly of the outer cap to the container body. It has many excellent effects, including the ability to
