Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mechanism for attaching and detaching a cartridge and a holder, which allows the cartridge and holder to be attached and detached without touching the cartridge.

[Problems to be solved by conventional techniques and ideas]

BACKGROUND ART Conventionally, compact cases have been used that can store and carry a plurality of applicators such as makeup stick containers and makeup brushes. However, it has the disadvantage that the case is long and difficult to carry, and to compensate for this disadvantage, the cosmetic stick container and applicator have been made smaller, making it difficult to use when applying.

[Means to solve problems]

The intermediate cylinder 8 is provided with an engaging protrusion 12 projecting from the lower end of the inner wall. A cam cylinder 10 rotatably and slidably installed below the intermediate cylinder 8 has a heart-shaped cam groove 11 carved in its outer peripheral wall with which the engaging protrusion 12 engages.

The pressing body 14 has a locking body 13 implanted at its lower end that penetrates the cam cylinder 10 and holds the cam cylinder 10 rotatably but not detachably. And this pressing body 14
is installed inside the intermediate cylinder 8 so as to be able to protrude and retract from the upper end.

The outer cylinder 9 into which the intermediate cylinder 8 is inserted and fixed is provided with a holding hole 16 in which a plate-shaped spring 17 is installed in the inner peripheral wall above the intermediate cylinder 8. Furthermore, a coil spring 15 is installed inside to urge the pressing body 14 upward.

The holding hole 16 of the holder 7 is composed of the intermediate cylinder 8, cam cylinder 10, pressing body 14 and outer cylinder 9.
Then, the tail body 2 of the cartridge 3 is inserted and held elastically by the plate spring 17, and the pressing body 14 is brought into contact with the bottom surface.

[Effect]

When the holder 7 exists alone, the engagement protrusion 12 of the intermediate cylinder 8 engages with the lower end of the heart-shaped cam groove 11, and the pressing body 14 protrudes from the upper end of the intermediate cylinder 8. ing.

Here, when the tail body 2 of the cartridge 3 is inserted into the holding hole 16 of the holder 7 and pushed down further against the elastic force of the coil spring 15 with the pressing body 14 in contact with the bottom surface, the intermediate cylinder 8 is Engagement protrusion 12
When the heart-shaped cam groove 11 is moved upward and the pressing is stopped, the engaging protrusion 12 engages with the upper end position of the heart-shaped cam groove 11, the amount of protrusion of the pressing body 14 is reduced, and the cartridge 3 is The tail body 2 is elastically held by the plate spring 17, and the holder 7
The cartridge 3 is now installed.

Then, when the cartridge 3 is pressed down again and then stopped, the pressing body 14 rises due to the elastic force of the coil spring 15, and the engaging protrusion 12 engages with the lower end position of the heart-shaped cam groove 11. In this state, the cartridge 3 is pressed by the pressing body 14 and ejected.

〔Example〕

A bar-shaped cosmetic tool such as a cosmetic stick container or a cosmetic tool is provided with an abutting stepped portion 1 at a lower portion thereof, and a tail body 2 is provided below this abutting step portion 1. Each of the cartridges 3 has an abutting step portion 1 and a tail body 2 of the same shape.
It is becoming.

Inside the case 4 that houses the cartridge 3, a holder 6 is rotatably supported and has a plurality of storage holes 5 for storing and holding the front side of the contact step 1 of the cartridge 3. There is.

Next, the holder 7 into which the tail body 2 of the cartridge 3 is removably fitted will be explained. The intermediate cylinder 8 is
The inner part is fixed inside the outer cylinder 9. A cam cylinder 10 is rotatably and slidably installed below the intermediate cylinder 8. A heart-shaped cam groove 11 is carved in the outer peripheral wall of the cam cylinder 10, and an engaging protrusion 12 protruding from the inner wall of the intermediate cylinder 8 is engaged with the heart-shaped cam groove 11. There is. A locking body 13 rotatably passes through the cam cylinder 10.
This anchoring body 13 is implanted at the lower end of a pressing body 14 that passes through the intermediate cylinder 8 in a vertically slidable manner. As a result, the cam cylinder 10 is rotatably held by the pressing body 14 and the engaging body 13, and the pressing body 14 and the engaging body 13 cannot be detached from the intermediate cylinder 8. Note that this pressing body 14 is configured such that even if the engagement protrusion 12 of the intermediate cylinder 8 engages with the upper end of the heart-shaped cam groove 11 of the cam cylinder 10, the upper end thereof protrudes from the intermediate cylinder 8. . In addition, the attachment body 13 and the outer cylinder 9
A coil spring 15 is installed between the bottom surfaces,
The pressing body 14 is pushed upward. Further, above the intermediate cylinder 8 is a holding hole 16 into which the tail body 2 of the cartridge 3 is inserted. A plate spring 17 is fixed to the inner circumferential wall of the holding hole 16 for elastically holding the tail body 2 of the cartridge 3 from the outer circumference. The elastic holding force of the plate spring 17 is stronger than the holding force of the storage hole 5 of the case 4 and weaker than the elastic force of the coil spring 15. Furthermore, when the tail body 2 of the cartridge 3 is inserted into the holding hole 16, the pressing body 14 is attached to the bottom surface of the tail body 2.
It is configured so that the two are in contact with each other.

Since the present invention has the above structure, when the holder exists as a single unit, the pressing body 14 protrudes to the middle of the holding hole 16, as shown in FIG. Further, as shown in FIG. 3, the engaging protrusion 12 of the intermediate cylinder 8
is engaged with the lower end of the heart-shaped cam groove 11 of the cam cylinder 10.

When the cartridge 3 is mounted on the holder 7, the pressing body 14 is slid by the tail body 2 of the cartridge 3, and the engaging protrusion 12 passes through the groove on the left side of the heart-shaped cam groove 11 to the position shown in FIG. , and is engaged in the position shown in FIG. 7 by the elastic force of the coil spring 15. Most of the pressing body 14 is recessed into the intermediate cylinder 8, the tail body 2 of the cartridge 3 is held by the plate spring 17, and the cartridge 3 is mounted.

Similarly, the cartridge 3 is inserted into the storage hole 5 of the case 4.
When the cartridge 3 is stored, the pressing body 14 is slid by the tail body 2 of the cartridge 3, and the engaging protrusion 12 comes into contact with the heart-shaped cam groove 11 at the position shown in FIG. Heart-shaped cam groove 1
Pass through the groove on the left side of 1 and engage in the position shown in FIG. The cartridge 3 is then pressed by the pressing body 14 and ejected to the outside.

The above operation is performed because the contact step part 1 of the cartridge 3 is in contact with the holding hole 16.
This can be done while the case 4 is housed in the housing hole 5.

[Effect of idea]

As described above, the present invention miniaturizes stick-shaped cosmetic tools such as cosmetic stick containers and cosmetic tools into a cartridge 3.
The disadvantage of making the cartridge easy to carry and making it difficult to use is solved by attaching the cartridge 3 to the holder 7 during use and making it easy to hold.

Also, the cartridge 3 and holder 7 can be attached and detached.
By pressing the holder 7 with the cartridge 3 stored in the case 4, the pressing body 14 moves forward and backward. When the pressing body 14 retreats, the cartridge 3 can be installed, and when the pressing body 14 moves forward, the cartridge 3 can be mounted.
The cartridge can be discharged without touching the cartridge 3 with one hand.
