Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a stick-shaped cosmetic dispensing container such as lipstick.

"Prior Art" As a stick-shaped cosmetic feeding container, generally, a screw cylinder is rotatably fitted to the outer surface of the main cylinder, and a pin is projected from the stick-shaped cosmetic support cylinder fitted in the main cylinder to form the pin. Is inserted into a vertical split groove vertically provided in the main cylinder, and the tip of the pin is engaged with the spiral groove on the inner surface of the screw cylinder, and the knob cylinder formed by the lower part of the main cylinder with respect to the screw cylinder is rotated in both forward and reverse directions. When the screw is turned to, the pin is pushed up and down in the spiral groove, and the support cylinder is moved up and down by being pushed down.

In this conventional container of this type, the knob cylinder has a large outer diameter, and the screw cylinder is fitted to the small outer diameter portion above the knob cylinder, and the pin of the support cylinder stops when reaching the lower end of the screw groove. Therefore, the support cylinder moves up and down only in the cylinder portion with the vertical split groove which stands up from the knob cylinder portion.

"Problems to be solved by the invention" In the conventional feeding container of this type, the pick-up tube portion at the lower end of the container and the portion immediately above the pick-up tube where the stick-shaped cosmetic product support tube is located when the stick-shaped cosmetic product descends are actually It is not used as a storage unit for stick-shaped cosmetics that are consumed by. For this reason, there is a drawback that the container body becomes too long as compared with the length of the stick-shaped cosmetic product.

The present invention makes it possible to increase the length of the bar-shaped cosmetic product storage portion in the container by forming the support cylinder so as to descend into the knob cylinder.

"Means for Solving the Problem" A knob cylinder 4 is erected from the outer periphery of the bottom wall 3 at the lower end of the inner cylinder 2 with a small gap between the inner cylinder 2 and the inner cylinder 2, and vertical split grooves 5, 5 are formed in the inner cylinder. A vertically arranged main cylinder 1 and a lower cylinder portion inserted into the small gap so that the cylinder portion is rotatably fitted to the outer surface of the inner cylinder, and screw threads 8 and 8 are formed on the inner surface of the cylinder portion. The cylinder 9 and the pins 12, 12 protruding from the outer surface of the cylinder part fitted in the inner surface of the inner cylinder 2 so as to be vertically movable
And a support tube 11 for a bar-shaped cosmetic which is inserted into the vertical groove and has the tip of the pin engaged in the screw groove, and the vertical groove 5, 5 and the screw groove 8, 8 are provided in the inner cylinder 2. The screw cylinder 9 is drilled to the respective lower end portions, and the vertical split grooves 5 and 5 are opened to extend to the lower surface of the bottom wall 3.

[Operation] In the state of FIG. 1, the support cylinder 11 for fitting the stick-shaped cosmetic product is located in the lower part of the container, the cap 14 is removed from this state, and the knob cylinder 4 is moved in the forward direction with respect to the screw cylinder 9. The support cylinder 11 rises by turning, and the support cylinder descends by turning in the opposite direction from the raised state.

[Example] The container of the present invention has a main cylinder, a screw cylinder, and a support cylinder for stick-shaped cosmetics.

The main cylinder 1 stands up from the outer periphery of the bottom wall 3 at the lower end of the inner cylinder 2 with a knob cylinder 4 standing with a small gap between the main cylinder 1 and the inner cylinder 2, and vertical split grooves 5, 5 are formed on the left and right sides of the inner cylinder 2. Are installed vertically. These vertical split grooves are extended to the lower surface of the bottom wall, and a through hole 6 is formed in the center of the bottom wall.
Has been drilled. Protrusions 7, 7 are attached to the outer surfaces of the left and right sides of the upper end of the inner cylinder to prevent the screw cylinder from being pulled out.

On the outer surface of the inner cylinder 2, a screw cylinder 9 having screw grooves 8, 8 on the inner surface.
Is rotatably fitted. The lower portion of the tubular portion forming the screw cylinder is fitted into the gap between the inner barrel 2 and the knob barrel 4, and the lower end of the tubular portion is placed on the bottom wall of the main barrel, The lower surface of the pull-out preventing projection 7 is engaged with the upper surface of the projection 10 provided around the inner surface of the upper portion.

Into the inner cylinder 2 described above, the support cylinder 11 for fitting the lower part of the stick-shaped cosmetic product is worn.
Is fitted so that it can move up and down. The support cylinder has pins 12 and 12 projecting from the outer surface of its cylindrical portion, and the pins are inserted into the above-described vertical dividing grooves 5 and 5 so that the tips thereof are slidably engaged with the inner surfaces of the screw grooves 8 and 8. ing. In addition, projections 13 and 13 for locking the stick-shaped cosmetics are projected inward from the inner surface of the cylindrical portion.

Reference numeral 14 denotes a cap, in which a peripheral wall 16 vertically extending from the periphery of the top wall 15 is fitted to the outer surface of the screw cylinder 9 and a cylindrical portion 17 vertically extending from the back surface of the top wall to the upper inner surface of the inner cylinder 2 is provided. There is.

[Advantage of the Invention] In the present invention, a small gap is formed between the inner cylinder 2 and the knob cylinder 4 of the main cylinder described above, and the lower cylinder portion is fitted into the small clearance to screw the outer cylinder to the outer surface of the inner cylinder 2. 9 is fitted, and the vertical split grooves 5 and 5 and the spiral grooves 8 and 8 are drilled to the lower ends of the inner cylinder and the screw cylinder, so that the support cylinder is lowered to the lower limit of the container. Since the support cylinder 11 is positioned inside the cylinder, the entire container portion above the knob cylinder can be used as the storage portion for the stick-shaped cosmetic product that is actually consumed. Can be formed compactly. The two vertical split grooves 5 and 5 formed on both the left and right sides of the inner cylinder 2 are normally closed at the upper end of one of the grooves to prevent the support cylinder 11 from being pulled out as shown in FIG. The lower end is located above the upper end surface of the pick-up cylinder 4, and the groove forming die is pulled out in the lateral direction to form the main cylinder 1. However, if the lower end of the groove is bored to the lower end of the inner cylinder 2 as described above, the mold cannot be removed laterally because of the gripping cylinder 4, so that such integral molding of the main cylinder 1 is impossible or impossible. It would be extremely difficult. However, since the lower ends of the vertical split grooves 5 and 5 are opened to the lower surface of the bottom wall 3 in the present proposal, it is only necessary to pull out the mold below the bottom wall 3, which makes it difficult to integrally form the main cylinder 1. Absent.
