Description

DETAILED DESCRIPTION OF THE INVENTION The present invention aims to provide a cartridge-type rod-shaped cosmetic container in which a cartridge tube can be easily and reliably attached to and removed from a container body with a single touch. In this structure, the container body has a hakama tube fitted and fixed on the outside of a rotating tube having a spiral groove on its inner surface, and a pin of an elevating shaft inserted into the rotating tube is engaged with the spiral groove. The elevating shaft is moved up and down by the rotation of the rotary tube, and the collection chuck, which is fitted and fixed to the hakama tube, is installed at the top of the rotary tube. The cosmetic tray and body barrel are inserted into each other to prevent rotation of the cosmetic tray by making the cosmetic tray and body barrel into shapes other than perfect circles, and a collection chuck is integrally attached to the bottom of the cosmetic tray, and a cartridge barrel is attached to the container body. When inserted, the collector chuck on the container body side engages with the annular groove formed on the outside of the lower part of the cartridge cylinder, and the collet chuck on the cartridge cylinder side engages with the small diameter flange formed on the upper part of the lifting shaft, and the cartridge cylinder side The collection chuck is compressed in the closing direction by the inner wall surface of the barrel, causing the chuck's claws to close, and the large diameter portion formed in the lower part of the barrel releases the pressure, allowing the chuck's claws to open. In addition, the collection chuck on the container body side opens when the taper surface of the large diameter flange protruding in the middle of the lifting shaft comes into pressure contact with the inner surface of the chuck, and when the pressure contact on the tapered surface is released. The gist of this is a structure in which the claws of the chuck can be closed.

The details of the present invention will be described below with reference to an embodiment shown in the drawings. A is a container body, b is a cartridge tube, and this cartridge tube b is detachably connected to the container body a, and after the bar-shaped cosmetic is used, it is A novel cartridge cylinder is coupled to the container body so that the container body a can be used repeatedly and continuously. 1 is a rotary tube having a spiral groove 2 on its inner peripheral surface; 3 is a hakama tube fitted and fixed on the outside of the rotary tube 1;
4 is an elevating shaft inserted into the rotary cylinder 1, and a pin 5
is engaged with the spiral groove 2, and the rotation of the rotary cylinder 1 causes the lifting shaft 4 to move up and down. 6 is rotating cylinder 1
This split washer is installed at the open end of the spiral groove 2 and serves as a stopper to prevent the pin 5 from slipping out from the upper end of the spiral groove 2 during the upward stroke of the lifting shaft 4. Reference numeral 7 denotes a collection chuck placed on the split washer 6, with a seat ring 7' integrally formed at the lower part thereof being fitted and fixed into the hakama tube 3, and the chuck 7 having vertical splits in several places. Nail 7″ at the tip
, and a tapered surface 7 is formed on the inside. Reference numeral 8 denotes an annular large-diameter flange projecting from the upper part of the lifting shaft 4, and has a tapered surface 8' on the lower side.
By pressing against the chuck, the tip of the chuck opens. 9 is a small-diameter flange formed on the upper part of the lifting shaft 4; 10 is a fitting protrusion that is fitted into a connecting hole formed in the cosmetic tray of the cartridge tube b; 11 is a middle fitting that is fitted and fixed to the hakama tube 3; Reference numeral 12 denotes a barrel of the cartridge barrel b, into which a cosmetic tray 13 is inserted, and the outer shape of the cosmetic tray 13 and the inner shape of the barrel 12 are made into elliptical shapes to prevent rotation of the cosmetic tray 13. cosmetics plate 1
A downward collecting chuck 14 is integrally attached to the lower part of the cosmetic tray 13, and the chuck 14 has several vertical splits and claws 14' formed at the lower end. It has been drilled. 1
6 is a large diameter part formed inside the lower part of the body barrel 12, and when the collection chuck 14 is located inside the large diameter part 16, the claw 14' of the chuck 14 is open and the cosmetic tray 13 is raised. Then, the chuck 14 is compressed by the inner wall surface of the body barrel 12, and the claw 1
4' is now closed.

Then, when the lifting shaft 4 is lowered to the lowest position and then strongly lowered one step further, the tapered surface 8' of the large-diameter flange 8 is brought into contact with the inner tapered surface 7 of the collection chuck 7.
, and the claws 7'' of the chuck 7 are in an open state. At this stage, when the cartridge cylinder b is inserted into the container body a and the lifting shaft 4 is slightly raised to release the pressure contact by the tapered surface 8', When the claws of the chuck 7 close and engage with the annular groove 17 formed on the outer circumferential surface of the lower part of the body barrel 12, the container body a and the cartridge barrel b are completely connected, and the lifting shaft 4 is raised. As it rises, the collection chuck 14 moves into the barrel 12, and the chuck 14 is compressed by the inner wall of the barrel 12, and the claw 14' is engaged with the lower side of the small diameter flange 9, that is, the chuck 14 When the cosmetic tray 13 is in the body case 12, the claw 14' is always engaged with the small diameter flange 9, so that the cosmetic tray 13 can be reliably lowered by lowering the lifting shaft 4. When replacing the cartridge cylinder b, the lifting shaft 4 is completely lowered, the chuck 14 of the cosmetic tray 13 is positioned at the large diameter portion 16, and when the lifting shaft 4 is lowered one step further, the chuck is removed by pressure contact of the tapered surface 8'. 7's claw 7'' and body barrel 12
The engagement relationship with the annular groove 17 is released, and the cartridge cylinder b can be easily removed.
In this state, when another new cartridge cylinder b is inserted into the container main body a and the lifting shaft 4 is raised one step, the claw 7'' of the chuck engages with the annular groove 17 of the body cylinder 12, and the cosmetics are continuously moved. The plate 13 can now be moved up and down.

As described above, in the present invention, when the cartridge cylinder b is inserted into the container body a, the body cylinder 1 of the cartridge cylinder b
The claws 7'' of the chuck 7 are engaged with the annular groove 17 formed in the cosmetic tray 2, and the claws 14' of the chuck 14 provided at the bottom of the cosmetic tray 13 are engaged with the small diameter flange 9 formed on the upper part of the lifting shaft 4, respectively. This makes it easy to connect the cartridge barrel b to the container body a, and moreover, as the cosmetic tray 13 rises, the claw 14' of the chuck 14 is firmly engaged with the small diameter flange 9 due to the pressure of the body barrel 12. The cosmetic tray 13 can be reliably lowered by lowering the lifting shaft 4, and the cartridge cylinder b can be easily connected to the container body a, and the cosmetic tray 13 can be moved up and down smoothly. This has the effect of providing a cartridge-type cosmetic container that is extremely convenient for use.
