Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a stick-shaped cosmetic container having improved means for assembling a long and slender container.

Problems to be Solved by Conventional Technology and Invention Although the number of parts and the assembling method of the container using the spiral tube in the rotary feeding container have been already established, the long size which has been particularly welcomed by consumers in recent years. In the case of thin containers (especially lipstick containers), there are problems in the spiral tube installation and the effect of preventing the container body from coming off due to strict adherence to slender containers, and these solutions are urgently needed.

The present invention aims to eliminate the above-mentioned drawbacks and to provide a slim stick-shaped cosmetic container having a strong pull-out strength by simplifying assembly.

Means for Solving the Problems The present invention is characterized in that the conventional drawbacks are eliminated by providing a plurality of notches in the upper part of the spiral cylinder, and an annular rib is provided on the outer peripheral surface. A body tube formed by forming a thick tube portion on the upper side and a thin tube portion on the lower side, and a groove formed in the upper inner peripheral surface engages with an annular rib of the body tube and is formed on the inner peripheral surface. A spiral cylinder having a spiral groove, and an outer peripheral surface of the leg cylinder slidably contacting a thick cylinder portion of the body cylinder and hanging downward at a lower portion of the leg cylinder slidably contacting a thin cylinder portion of the body cylinder. A pin projecting from the lower part of the cylinder penetrates a vertical hole formed in the thin cylinder part of the body cylinder and engages with the spiral groove of the spiral cylinder, and an opening is formed in a part of the bottom wall. A hakama, which is drilled and arranged outside the spiral cylinder,
It is made up of a filler tube which is interposed between the hull cylinder and the spiral tube to firmly maintain the integral relationship between the spiral tube and the hail tube, and a plurality of notches are formed in the vertical direction of the upper end of the spiral tube. Split,
The gist is a configuration in which the inner tube comes into close contact with the outside of the spiral tube.

EXAMPLE An example of the present invention will be described below with reference to the drawings. 1 indicates that a single annular rib 2 projects on the outer periphery of the intermediate portion, with the annular rib 2 as a boundary, the upper portion is a thick tubular portion 1a and the lower portion is slightly smaller than this. A body tube 3 formed into a slender thin tube portion 1b is fitted to the lower half portion of the body tube 1, that is, the outer side of the thin tube portion 1b, and has a single groove 4 formed in the upper inner peripheral surface. Is a spiral cylinder having a spiral groove 5 on the inner peripheral surface formed by engaging with the annular rib 2 of the body cylinder 1. The spiral cylinder 3 has a plurality of notches 6 extending in the longitudinal direction at the open end. The openings are provided at intervals so that the opening can be elastically opened and compressed. Reference numeral 7 denotes an inner plate which holds cosmetics, and a leg cylinder 8 which is slidably contacted with the inner peripheral surface of the thick tube portion 1a of the body cylinder 1 and integrally formed on the lower portion of the inner plate 7 is The diameter is slightly reduced, and the pin 9 which is slidably contacted with the inner peripheral surface of the thin tube portion 1b of the body tube 1 and protrudes from the lower portion of the leg tube 8 penetrates the vertical hole 10 formed in the thin tube portion 1b. The spiral groove 5 of the spiral cylinder 3 is engaged. Reference numeral 11 denotes a hull cylinder having an opening 12 formed in a bottom wall thereof, and the middle plate 7 can be filled with a cosmetic material through the opening 12, and 13 denotes the hakama 1
1 and the spiral tube 3 are forcibly inserted into the spiral tube 3, and the insertion of the hollow tube 13 allows the spiral tube 3 and the hollow tube 1 to be inserted.
3 and the three parts of the hakama 11 are firmly held, and the opening of the spiral tube 3 is pressed in the diameter reducing direction by the compression of the inner tube 13 so that the engagement relationship between the annular rib 2 and the concave groove 4 is further secured. As a result, a firm effect of preventing the body tube 1 from coming off can be obtained. Incidentally, 14 is a cap that is detachably engaged with the inner tube 13.

The operation and effect of the invention. Therefore, according to the present invention, when the case 1 is rotated by holding the body tube 1, the inner tube 13 assures the integral relationship between the case 11 and the spiral tube 3, so that the spiral tube 3 as well. The inner tray 7 in the body tube 1 moves up and down as a unit, and the inner tray 7 is placed in the thick tube portion 1a of the body tube 1 and the leg tube 8 is placed in the thin tube portion 1b. Since it moves while slidingly contacting the peripheral surface, it is possible to obtain a very safe and smooth cosmetic product without causing rattling or the like when the inner plate 7 moves up and down, and the body tube 1 is attached to the outer periphery of the middle part. The leg cylinder 8 of the inner tray 7 is necessarily set in the diameter reducing direction by forming the thick tubular portion 1a on the upper side and the thin tubular portion 1b on the lower side with the protruding annular rib 2 as a boundary. There is an advantage that a long and slender smart container can be obtained. In particular, the present invention has a plurality of notches 6 provided in the longitudinal direction of the open end of the spiral tube 3 so as to divide the open part. It is possible to elastically open and compress, and it is easy to assemble parts and reduce extra labor, resulting in a low-cost product and the spiral tube by the inner tube 13 fitted to the outside of the spiral tube 3. The opening of 3 is compressed in the diameter reducing direction, and the engagement relationship between the annular rib 2 and the concave groove 4 is further strengthened, and as a measure for preventing the body barrel 1 from coming off, the rotation action of the spiral barrel 3 is actually prevented. It has an excellent effect.
