Description

[Detailed description of the invention] This invention relates to a stick-shaped cosmetic container that can be fed out from both ends, and more specifically, to a stick-shaped cosmetic container that can selectively feed out stick-shaped cosmetics of two colors from both ends. It is.

As for the conventional bar-shaped cosmetic container as mentioned above,
0-10932 and Utility Model Application Publication No. 50-102569 are publicly known.

However, in these known rod-shaped cosmetic containers, a screw frame or a screw tube is attached to each of the cosmetic-accommodating members disposed on both sides, and these extend to the center of the container and are rotatably provided. The threaded frame or threaded barrel is provided with a groove so as to be screwed into the female threaded hole of the cap, and to be drawn out by rotation of the cap, so as to engage with the retaining protrusion. .

Therefore, each screw frame or screw tube is provided with a threaded portion and an engaging portion with the engaging protrusion, and since these screw frames or screw tubes are formed relatively elongated, the operation of feeding out the cosmetic is easy. It doesn't happen smoothly.

In addition, special care must be taken to prevent the screw frame and/or screw tube from interfering with each other in the center of the container, so there is a problem in that assembly is relatively troublesome.

The present invention has been made to solve the above-mentioned problems, and its purpose is to provide a rod-shaped cosmetic container with both ends that can be easily assembled and has fewer threaded parts, allowing for smooth dispensing operations.

The present invention will now be described in detail with reference to the accompanying drawings, which illustrate preferred embodiments of the present invention.

In the figure, a spiral tube 1 is located in the center of the rod-shaped cosmetic container, and a screw thread 1a is formed on the inner wall surface of the spiral tube 1, and annular flanges 1b-- 1b
This collar 1b1b is rotatably fitted into the annular recesses 2a, -2a of the pair of middle cylinders 2-2.

A fixed tube 3 is disposed inside this spiral tube 1, and both ends 3a-3a of this fixed tube 3 are polygonal, and the middle tube 2
-2 is fitted and fixed to the polygonal elements 2b-2b formed on the inner wall surface.

Also, a pair of slits) 3b- are provided in the axial direction of the wall surface of the fixed cylinder 3.
3b are formed facing each other.

A slide rod 4 made of a magnetic material is slidably disposed inside the fixed cylinder 3, and a pair of projecting pieces 4a-4a are provided on both end sides of the slide rod 4 to protrude in opposite directions. )3b-3b protrudes outward, and this protruding piece 4a-4
a is engaged with the thread 1a of the spiral tube 1.

With such a structure, when the spiral tube 1 is rotated, the slide rod 4 slides back and forth within the fixed tube 3, and one end of the slide rod 4 plunges deeply into one of the middle tubes 2.

An annular rib 2C is formed on the substantially central inner wall surface of each middle cylinder 2, into which a cylinder 5 made of a magnetic material and having an annular wall surface 5a is fitted.

Further, a cylinder cap 6 is fitted to the outer end of each inner cylinder 2, and a bar-shaped cosmetic 7 is housed therein by being attached to an inner plate 8, and a disk-shaped A permanent magnet 9 is fixedly attached.

Therefore, due to the magnetic attraction between the magnetic cylinder 5 and the permanent magnet 9, the inner tray 8 and the rod-shaped cosmetic 7 accommodated therein are
is biased toward the magnetic cylinder 5, and when the slide rod 4 is on the left side of the center and the right end of the slide rod 4 is separated from the permanent magnet 9 on the right side as shown in FIG. A permanent magnet 9 is attracted to the magnetic cylinder 5, so that the bar-shaped cosmetic material 7 on the right side is housed within the cylinder cap 6 and is not exposed to the outside.

When the spiral tube 1 is rotated clockwise or counterclockwise, the interior thereof and the slide rod 4 slide forward or forward.

As a result, when one end of the slide rod 4, for example, the left end as shown in FIG. The rod-shaped cosmetic material 7 housed in the container is moved to the left side, and the rod-shaped cosmetic material 7 is projected to the outside from the tube cap 6 to be used.

On the other hand, when the spiral tube 1 is rotated in the opposite direction to the above case, the slide rod 4 moves to the right from the position shown in FIG.

At this time, since the slide rod 4 is made of a magnetic material, the permanent magnet 9 on the left inner tray is attracted to it, and as the slide rod 4 moves to the right, the rod-shaped cosmetic 7 on the left side is attracted to the slide rod 4.
is also moved to the right side and stored inside the cylinder cap 6.

Thereafter, when the spiral tube 1 continues to be rotated further, the right end of the slide rod 4 shown in FIG. is projected outward and made available for use.

As is clear from the above description, in the dispensing structure of the rod-shaped cosmetic container of the present invention, the slide rod 4 that slides back and forth within the spiral tube 1 is formed of a magnetic material, and both ends of the slide rod 4 are connected to the rod-shaped cosmetic container. The rod-shaped cosmetic material 7 -7 is fixed at a predetermined extended position, and the structure for storing and fixing it inside from this extended position is simple.Furthermore, in this extended structure, the threaded portion is the spiral tube 1 and the slide rod 4. Therefore, it is possible to achieve reliable operation and low cost.

Further, a fixed cylinder 3 is arranged inside the spiral cylinder 1, a slide rod 4 is slidably arranged inside the fixed cylinder 3, and protrusions 4a-4a are provided at both ends of the slide rod 4. When the slits are made to protrude from the pair of opposing slits 3b-3b formed in the fixed cylinder 3 and engage with the thread 1a of the spiral cylinder 1,
The axial movement of the elongated slide rod 4 becomes stable, and as a result, the rod-shaped cosmetic material 7-7 is smoothly fed out.
