Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a stick-shaped cosmetic dispensing container such as a lipstick. More specifically, the present invention has a function of fitting and holding a stick-shaped cosmetic and protecting the stick-shaped cosmetic. It relates to a lifting cylinder.

[0002]

2. Description of the Related Art Conventionally, a stick-shaped cosmetic dispensing container such as a lipstick is used to raise and lower a rod-shaped cosmetic by screwing an elevating cylinder holding a stick-shaped cosmetic into a spiral dispensing mechanism and performing a rotational dispensing operation. Was moving. The spiral feeding mechanism includes a guide cylinder provided with a guide groove for guiding the elevating cylinder in a vertically slidable manner so as to be non-rotatable, a spiral cylinder provided with a spiral groove in a side wall, and covers the guide cylinder and the spiral cylinder. It was made up of an exterior body. A threaded piece that penetrates the guide groove and is screwed into the spiral groove is provided on the side wall of the lift cylinder, and is configured to move up and down by the relative rotation of the guide cylinder and the spiral cylinder.

[0003]

Therefore, the lifting cylinder has been connected to the feeding mechanism by a screwing piece. In other words, when an impact is applied to the container body, the impact is transmitted to the rod-shaped cosmetic via the threaded piece, and there is a risk that the rod-shaped cosmetic may be damaged or fall off due to the impact. . Further, when the application pressure of the bar-shaped cosmetic is too strong, there is a risk that the bar-shaped cosmetic is broken from the mouth of the elevating cylinder in which the bar-shaped cosmetic is fitted and held.

In particular, in a configuration in which a guide tube or a spiral tube is arranged around a rod-shaped cosmetic, it is impossible to directly fill the container with the rod-shaped cosmetic. It had to be inserted and held. Therefore, a certain amount of gap is generated between the stick-shaped cosmetic and the inner wall of the container. Due to this gap, there is a high risk that the bar-shaped cosmetic is broken.

[0005]

Means for Solving the Problems The present invention provides a stick-shaped cosmetic 2
The lifting cylinder 1, which is fitted and held, and is moved up and down by a feeding mechanism 8, comprising a holding portion 3 for fitting and holding the rod-shaped cosmetic material 2 and a screwing piece 7 screwed to the feeding mechanism 8. The cushion member 6 is arranged between the portion 4 or between the screwing piece 7 and the screwing portion 4, and the cushion member 6 buffers shock, stress, and the like applied to the stick-shaped cosmetic 2.

[0006]

When the feeding mechanism 8 is operated, the feeding mechanism 8 is operated.
Since the screwing piece 7 is screwed into the cylinder, the elevating cylinder 1 moves up and down,
The stick-shaped cosmetic 2 is paid out. Further, when an impact or the like is applied to the container body 9, the cushion member 6 buffers the impact and prevents the rod-shaped cosmetic 2 from being damaged. Similarly, when an excessive application pressure is applied to the stick-shaped cosmetic material 2, the cushion member 6
Buffer the application pressure and prevent breakage of the bar-shaped cosmetic material 2.

[0007]

[Embodiment 1] The elevating cylinder 1 is composed of a holding cylinder 3 and a threaded portion 4.
Has become. The holder 3 holds the stick-shaped cosmetic 2
And screw down the threaded part 4 which has a cylindrical shape from the center of the lower end.
ing. The outer diameter of the screw portion 4 is larger than the outer diameter of the holding portion 3.
It has a small diameter. Also, on the outer wall at the lower end of the threaded portion 4
Is provided with a disk-shaped flange 19 having the same diameter as the outer diameter of the holding portion 3.
Have been. The flange 19 is configured to be able to bend up and down.
And a pair of screwing pieces 7 protruding from its end.
I have. As a result, the flange 19 bends up and down to absorb the impact
Cushion member 6 to be transmitted to the stick-shaped cosmetic material 2.
It is designed to block.

Next, a reciprocating operation for vertically moving the elevating cylinder 1
The container body 9 in which the dispensing mechanism 8 is provided will be described. Lifting
The tube 1 is provided inside the guide tube 10 so as to be slidable up and down.
You. On the side wall of the guide tube 10, the screw 7 of the elevating tube 1 is attached.
Penetrates and raises / lowers cylinder 1 so that it cannot rotate inside guide cylinder 10
A guide groove 11 for sliding downward is slid vertically.
Have been. This guide groove 11 is provided in a pair,
It is provided at a position corresponding to the threaded piece 7 of the tube 1. this
The spiral cylinder 12 is rotatably detached from the outer wall of the guide cylinder 10.
It is held immovably. This spiral cylinder 12 is made of thin metal.
The screwing piece 7 of the lifting cylinder 1 is screwed
Two spiral grooves 13 are provided. This spiral tube 12
Is fixed in the sleeve 14 so that it cannot fall off and cannot rotate.
You. This sleeve 14 covers the upper part of the guide cylinder 10
I have. Then, the lower end of the guide cylinder 10 stops inside the outer cylinder 15.
Is being worn. At the upper end of the outer cylinder 15, a middle cylinder 16 is fixed.
Is being worn. On the upper part of the middle cylinder 16,
Fits when projecting from the end and the cap 17 is fitted when pulled out
A part 18 is provided. As a result, the sleeve 14 is retained.
By rotating the outer cylinder 15 while holding the guide cylinder 1
0 and the helical cylinder 12 rotate relative to each other, forming a rod by screwing action.
The cosmetic 2 is configured to move up and down.

A flange 19 is provided on the outer wall at the lower end of the threaded portion 4.
Instead, it is also possible to directly project the threaded piece 7. This place
In this case, it is necessary to protrude the engagement piece 7 outwardly from the holding portion 3.
You. As a result, the cushion in which the threaded pieces 7 themselves have elasticity
It becomes member 6. The elevating cylinder 1 is connected to the spiral feeding mechanism 8.
Therefore, any structure Tsu der if the structure to be moved up and down
It can also be implemented.

[0010]

[Embodiment 2] An elevating cylinder 1 has a holding part 3 at an upper part and a screw part at a lower part.
A joint 4 is provided. The holder 3 has a stick-shaped makeup
Charge 2 is retained. Also, the lower outer wall of the screw portion 4
Is provided with a pair of threaded pieces 7. This screw is
It is divided vertically into two parts from the tip. As a result, it is split into two
A cushion member in which the threaded piece 7 is bent and absorbs impact.
6 so that the transmission to the stick-shaped cosmetic 2 is stopped.
ing. In addition, the longer the length of this screwing piece 7, the more cushion
The effect is higher. Therefore, the screwing portion 4 is changed as in the second embodiment.
The holding portion 3 is configured to have a smaller diameter than the outer diameter.
A long screwing piece 7 is protruded, and this screwing piece 7 is
If divided, a higher cushioning effect can be expected.
The elevating cylinder 1 is moved up and down by the spiral feeding mechanism 8.
It can be implemented with any configuration
You.

[0011]

As described above, according to the present invention, the rod-shaped cosmetic 2 is fitted and held, and the lifting cylinder 1 which is moved up and down by the feeding mechanism 8 is extended with the holding cylinder 3 which fits and holds the rod-shaped cosmetic 2. A cushion member 6 is disposed between the screw portion 4 provided with a screwing piece 7 screwed to the mechanism 8 or between the screwing piece 7 and the screwing portion 4. Shocks, stresses, etc. Therefore, even if an unexpected stress acts on the stick-shaped cosmetic material 2 when carrying or using the stick-shaped cosmetic material dispensing container such as a lipstick, the cushion member 6 buffers the stress, and the stick-shaped cosmetic material 2 falls off or is damaged. And breakage can be prevented.
