Description

[Detailed description of the invention] This invention relates to an improvement of a roll-up cosmetic bar that allows the cosmetic bar to be attached from the tip.More specifically, the cosmetic bar is made into a cartridge, and this cartridge can be attached and removed from the tip. This invention relates to a flexible rod-shaped cosmetic container.

Conventionally, this type of rod-shaped cosmetic container was produced in Utility Model Publication in 1973-52.
521 is publicly known.

In this known cosmetic container, a rod-shaped cosmetic is housed in a cylindrical body, a disk is fitted into the rear end of the cosmetic to form a cosmetic cartridge, and this disk is screwed into the tip of a threaded rod of a feeding mechanism. I try to do that.

However, in this known cosmetic container, when installing the cartridge, the sleeve tube cap at the tip of the container is removed, the cartridge is inserted from the tip side, and while holding the tube with one hand, the threaded rod is drawn out and screwed into the disc. After
It was necessary to reattach the cylinder cap, making cartridge installation relatively troublesome.

In addition, the cylindrical body of this cartridge is rotatably fitted loosely inside the tip of the container, so when the threaded rod is rotated and screwed into the disc, the entire cartridge rotates and this screwing can be done smoothly. There was a flaw that said it was not fixed.

The present invention is intended to improve the above-mentioned conventional defects, and its purpose is to provide a rod-shaped cosmetic container that is extremely convenient to use and allows a cosmetic cartridge to be installed extremely easily with a one-touch operation.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes the rear cylinder of the lifting container, and the cylinder 1 has a rectangular hole 1a with a polygonal cross section formed at the rear inside thereof, and an annular groove 1b formed in front of the square hole 1a.

A threaded rod 2 is fitted into this cylinder 1, and a polygonal portion 2a formed at the rear end of this threaded rod fits into the square hole 1a, allowing movement of the threaded rod 2 in the axial direction. However, this rotation is not allowed.

A middle cylinder 3 is further fitted into the front part of this cylinder 1.
An annular projection 3a formed on the outer periphery of the cylinder body 1 is loosely fitted into the annular groove 1b of the cylinder body 1, so that the cylinder body 1 is rotatable with respect to the middle cylinder 3.

Further, a projecting piece 3b is formed on the inner surface of the rear end of the middle cylinder 3, and this projecting piece 3b is configured to engage with the thread groove 2b of the threaded rod 2 when the middle cylinder 3 is inserted into the cylinder body 1. Therefore, when the cylinder body 1 is rotated relative to the middle cylinder 3, the threaded rod 2 is configured to be raised or lowered while rotating along the axis of the cylinder body 1 by engagement with the protruding piece 3b. .

In the present invention, an inner plate 5 that receives a rod-shaped cosmetic material 4 and has a thread 5a formed on the rear outer circumferential surface, a small cylinder 6 that has an internal thread 6a that is removably screwed into the thread 5a of the inner plate 5, Bar-shaped cosmetics 4
A sleeve cylinder body 7 that encloses and tightly fits around the outer periphery of the small cylinder 6.
A cosmetic cartridge 8 was constructed from the above, and the cartridge 8 was made detachable from the above-mentioned container.

In this specific embodiment, an axial blind hole 5b is formed inside the rear end of the inner plate 5, and a plurality of grooves are formed on the inner surface of the blind hole 5b. It is designed to tightly fit into the protrusion formed on the portion 2C.

Further, the small cylinder 6 has a seat ring 6b at its inner end, and a knurled portion 6C is formed on its outer peripheral surface.
C is adapted to engage with a knurled portion 7a formed on the inner circumferential surface of the rear end of the sleeve cylinder body 7.

Moreover, the pitch of the thread 5a of the inner plate 5 and the inner thread 6a of the small cylinder 6 that is threaded therewith is equal to the pitch of the thread groove 2b formed on the outer periphery of the threaded rod 2, so that when the threaded rod 2 is advanced, When the inner plate 5 rotates with the rotation of the threaded rod 2,
The thread 5a of the inner plate 5 is configured to be drawn out while rotating along the internal thread 6a of the small cylinder 6.

In the figure, reference numeral 9 indicates a gripping outer cylinder, which is press-fitted onto the outer periphery of the cylinder 1 so that the cylinder 1 also rotates as the outer cylinder 9 rotates.

In assembling the cosmetic cartridge 8 of the rod-shaped cosmetic container having the above structure, as shown in FIGS. 2a-C,
First, the small cylinder 6 is screwed onto the inner plate 5, and the cosmetic bar 4 is inserted into the front hole of the inner plate 5 and fixed.Then, the cosmetic bar 4 is covered with the sleeve cylinder 7, and the cosmetic bar 4 is wrapped in the sleeve cylinder 7. Knurling part 7
a into the knurled portion 6C of the small cylinder 6.

Next, in order to attach this cosmetic cartridge 8 to the refill container, insert this cartridge 8 into the inner tube 3, push the rear end blind hole 5b of the inner tray 5 into the tip 2C of the threaded rod 2, and fit tightly. Just let it happen.

After the cosmetic cartridge 8 is attached to the container in this manner, when the outer cylinder 9 is rotated, the internal threaded rod 2 is also rotated as described above.

An inner plate 5 is fixed to the tip 2C of this threaded rod 2 and rotates at the same time, but since the small cylinder 6 is fixed to the sleeve cylinder body 7, the inner plate 5 is fixed to the inner thread 6a of the small cylinder 6. It moves forward from the small cylinder 6 while rotating along the axis, whereby the bar-shaped cosmetic 4 housed in the inner tray 5 is drawn out from the sleeve cylinder body 7 and ready for use.

Further, when the outer cylinder 9 is rotated in the opposite direction to the above case, the threaded rod 2 and the inner plate 5 fixed thereto move backward while rotating, and the inner plate 5 is screwed into the inside of the small cylinder 6 and deepens. enter,
The bar-shaped cosmetic material 4 is lowered into the inside of the sleeve cylinder body 7.

Further, when the bar-shaped cosmetic decreases as a result of use and needs to be replaced, the sleeve cylinder body 7 is pulled out from the inner cylinder 3 and the cosmetic cartridge 8 is removed.

Next, a new cosmetic cartridge 8 constructed in the same manner as described above is inserted into the tip of the inner tube 3 of the dispenser container, and can be used again.

As described above, in the bar-shaped cosmetic container of the present invention, the retractable container and the cosmetic cartridge 8 for storing the bar-shaped cosmetic 4 are formed separately so as to be detachable.
The cosmetic can be easily attached, removed and replaced without touching the bar-shaped cosmetic 4 inside by holding the sleeve cylindrical body 7, and is hygienic and there is no fear that the cosmetic will bend.

The cosmetic cartridge 8 also includes an inner plate 5 that receives a bar-shaped cosmetic and has a thread 5a formed on its outer peripheral surface, and a small cylinder 6 with an inner screw 6a that is removably screwed into the thread 5a of the inner plate 5. and a sleeve cylinder body 7 which encloses the bar-shaped cosmetic material 4 and tightly fits around the outer periphery of this small cylinder 6, so this cartridge 8 is pushed into the middle cylinder 3 from the front of the container. The incorporation of the Toridine 8 into the lifting container is completed with a one-touch operation of securing and fixing the dish 5 and the tip 2C of the threaded rod 2, which greatly simplifies the replacement of the bar-shaped cosmetic 4. .

Further, a knurled portion 6C is formed on the outer circumferential surface of the small cylinder 6, and a knurled portion 7a is formed on the inner circumferential surface of the rear end of the sleeve cylinder 7, so that the sleeve cylinder 7 is connected to the small cylinder 6 by the double-ended portion.
Since the small cylinder 6 is firmly fixed to the sleeve cylinder body 7 against the rotation of the inner plate 5, the operation of dispensing the bar-shaped cosmetic can be carried out smoothly and reliably. can.
