Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a dispensing container that dispenses a bar-shaped cosmetic and is replaceable in a cartridge type manner.

[Conventional technology]

BACKGROUND ART Conventionally, a dispensing container has been proposed in which a bar-shaped cosmetic is detachably connected to the dispensing container, and the container can be replaced like a cartridge. One example is the one described in Japanese Utility Model Application Publication No. 163020/1983, which was previously filed by the present applicant.

Its structure is as shown in FIG.
A cartridge 20 is detachably attached inside the container body 1, and a joint tube 41 is fitted and fixed in the tip of the container body 1, and the cartridge 20 is inserted into the joint tube 41. Cartridge body 2
A tail plug 24 fitted and fixed to the base end of the spiral tube 3
It is rotatably supported on the inner surface of the cartridge supporting cylindrical body 9 at the tip of the cartridge. When the container body 1 rotates, the spiral tube 3 fitted and fixed to the inner surface of the container body 1 rotates, causing the push rod 4 inside the spiral tube 3 to advance in the axial direction. Then, when the push rod 4 advances,
The tip of the push rod 4 pushes the core chuck 22 in the advancing direction against the biasing force of the spring 23. The rod-shaped cosmetic 30 attached to the core chuck 22 is used by protruding from the tip of the cartridge body 21.

[The problem that the idea attempts to solve]

However, in the conventional example shown in FIG.
After using the bar-shaped cosmetic 30, unless the container body 1 is rotated by hand, the push rod 4 will not move back and the bar-shaped cosmetic 30 will not be stored in the cartridge 20.

When replacing the cartridge 20 with the bar-shaped cosmetic material 30 protruding, the push rod 4 also remains in the extended state, so the new cartridge 2 is replaced.
0 into the container body 1, the bar-shaped cosmetic 30
Since the bar-shaped cosmetic material 30 protrudes, it is necessary to rotate the container body 1 each time to store the bar-shaped cosmetic material 30 in the cartridge 20.

The present invention was developed in view of the above-mentioned matters, and when the cartridge 20 is removed after using the bar-shaped cosmetic 30, the push rod 4 that has been advanced automatically returns and a new cartridge 20 is inserted into the container body 1. To provide a technology that enables a cartridge type cosmetic bar dispensing container in which a cartridge 20 is attached with a cosmetic bar 30 stored therein to be formed with a simple structure and without having to have a large diameter. This will be a major issue.

[Means to solve the problem]

The present invention has the following configuration in order to solve the above technical problem.

That is, the spiral tube 3 is fitted into the cylindrical container body 1,
A push rod 4 is screwed into the spiral tube 3, and the push rod 4 is urged in a backward direction by a spring 7, and a cartridge supporting cylindrical body 9 is provided at the tip of the spiral tube 3. , the container body 1 includes:
The base of the cartridge 20 is rotatably fitted,
This cartridge 20 has a cylindrical tail plug 24 fitted and fixed to the base end of a cartridge body 21, and this cylindrical tail plug 24 is provided with a through hole 26.
6 is provided with a locking portion 27 formed in the vertical direction, and inside the cartridge body 21 is a bar-shaped cosmetic 30 for mounting, which is biased in a backward direction by an elastic spring 23. The core chuck 22 is inserted so as to be slidable back and forth, and the cylindrical tail plug 24 of the cartridge 20 inserted into the container body 1 is rotatably inserted into the cartridge supporting cylindrical body 9. The push rod 4, which is fitted in such a way that it cannot be slid forward or backward, and which is inserted into the cylindrical tail plug 24, is locked by the locking portion 27 provided in the longitudinal direction.
The cartridge type rod-shaped cosmetic dispensing container is made non-rotatable and slidably inserted.

[Effect]

When inserting and attaching the base of the cartridge 20 into the container body 1, insert the cylindrical tail plug 24, which is fitted and secured to the base end of the cartridge body 21, into the container body 1 first. A cylindrical tail plug 24 is inserted into the cartridge supporting cylindrical body 9 at the tip of the cylinder 3, and is fitted so that the cylindrical tail plug 24 can rotate but cannot slide forward or backward. When the cylindrical tail plug 24 is inserted into the cartridge supporting cylindrical body 9, the push rod 4
is inserted into the cylindrical tail plug 24 and comes into contact with the end surface of the core chuck 22.

When feeding out the bar-shaped cosmetic material 30, the cartridge body 21 is held and fixed, and when the container body 1 is rotated, the push rod 4 screwed into the spiral tube 3 advances in the axial direction against the biased spring 7. , core chuck 2
Press the end face of 2. Then, as the push rod 4 advances, the core chuck 22 advances against the biased spring 23. And bar-shaped cosmetics 30
is fed out from the cartridge body 21 and ready for use.

Note that when the cartridge 20 is removed from the container body 1 while the push rod 4 is extended, the cylindrical tail plug 24 is removed from the push rod 4, so that the push rod 4 becomes rotatable. Since the push rod 4 is biased in the backward direction by the spring 7, it automatically moves backward while rotating. Therefore, when a new cartridge 20 is attached to the container body 1, the cartridge 20 can be attached with the bar-shaped cosmetic 30 housed in the cartridge body 21.

This cartridge-type, rod-shaped cosmetic dispensing container has a locking portion 27 formed in the vertical direction on the inner surface of the through hole 26 of the cylindrical tail plug 24 that is fitted and fixed to the cartridge main body 21, and a locking portion 27 formed in the vertical direction. tail plug 24
The push rod 4 is rotatably and non-slidably fitted into the cartridge supporting cylindrical body, and the push rod 4 inserted into the cylindrical tail plug 24 is connected to the lock provided in the longitudinal direction. Due to part 27, it cannot be rotated,
Slidably inserted.

Then, the rotational force of the cartridge body 21 is transmitted from the cartridge body 21 to the cylindrical tail plug 24,
It is transmitted directly from the cylindrical tail plug 24 to the push rod 4 and rotates the push rod.

Therefore, the cartridge-type rod-shaped cosmetic dispensing container of the present invention has a simple structure for the rotational force transmission mechanism, which is the most complicated structure, and can be formed without increasing the diameter of the container body 1.
