Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a dispenser cosmetic stick container.

[Conventional technology]

Conventionally, a dispensing container with an internal mechanism for dispensing cosmetic sticks below the cosmetic stick has a structure that utilizes the screwing action of a set of screws. Therefore, increasing the length of the cosmetic stick would increase the overall length of the container, making it ungainly.

In view of this, cosmetic stick containers have been proposed that have a mechanism for extending the cosmetic stick by overlapping and screwing together a number of screws having different outer diameters. With this configuration, the length of the mechanism for extending the cosmetic stick has been shortened.

[Problem that the invention attempts to solve]

However, this feeding mechanism has the disadvantage that the outer diameter is increased because a rotation prevention mechanism is required for each screw.

[Means for solving problems]

The inner plate 12 which holds the cosmetic rod is cut at the bottom, has an engaging projection 14 protruding from the lower end of the outer wall, and has a leg tube 13 with a screw-fitting piece 10' protruding from the lower end of the inner wall hanging down.

A sleeve 9 that slidably houses this inner plate 12
In this case, an engagement groove 15 that engages with the engagement protrusion 14 of the leg tube 13 is vertically bored.

Middle cylinder 11 inserted and fixed into this sleeve 9
A cutout 17 is provided into which the leg tube 13 enters when the inner plate 12 is lowered, and a screwing piece 10 is provided protruding from the lower end of the inner wall.

The threaded cylinder 7 has a threaded piece 1 of the middle cylinder 11 on its outer wall.
0 and the upper right spiral groove 5 and the leg tube 13
The left upward spiral groove 6 which is screwed into the screwing piece 10' is intersected and screwed to form a rotation stopper engagement hole 16.

The rotation stopper engagement rod 4, which is slidably but unrotatably inserted into the rotation stop engagement hole 16, penetrates the bottom of the middle cylinder 11 at its lower end and rotatably holds the middle cylinder 11. A cylindrical fastening part 8 that is inserted into the tail plug 2 and fastened thereto is provided.

The tail plug 2 is fixed to the base tube 1.

[Effect]

When the sleeve 9 is held and the base cylinder 1 is rotated,
The rotation stopper engagement groove 4, which is fixed to the tail plug 2 which is inserted into the base cylinder 1 and fixed thereto, by the cylindrical fastening portion 8, also rotates. Then, the threaded cylinder 7 interlocks with the base cylinder 1 because the rotation stopper engagement rod 4 is inserted into and engaged with the rotation stopper engagement hole 16. At this time, the threaded piece 10 protruding from the upper end of the middle cylinder 11 fixed in the held sleeve 9 is screwed into the right upward spiral groove 5 of the threaded cylinder 7, so that the threaded cylinder 7 is It is something that rises.

On the other hand, when the leg tube 13 is in a state where the engagement protrusion 14 engages with the engagement groove 15 of the sleeve 9 and the rotation is prevented, the threaded piece 10' protruding from the inner wall of the lower end is attached to the left side of the threaded tube 7. Since it is screwed into the spiral groove 6, it rises together with the inner plate 12.

That is, the inner plate 12 that accommodates and holds the decorative stick rises due to the threaded engagement of the leg tube 13 hanging from the bottom with the threaded tube 7, and the rise of the threaded tube 7 due to the screwed engagement of the middle tube 11 and the threaded tube 7. Due to the action of the two screws, it moves at twice the pitch of the spiral groove threaded into the threaded tube 7.

〔Example〕

The tail plug 2, which is inserted and fixed into the base tube 1, is fixed with a cylindrical fastening part 8 provided at the lower end of a hexagonal pillar-shaped rotation stopper engagement rod 4. At this time, the cylindrical fastening part 8
penetrates the bottom of the middle tube 11 and holds the middle tube 11 so as to be rotatable but not to fall off. This middle cylinder 11
A pair of cut portions 17 are provided on the side wall, and a screwing piece 10 is further provided protruding from the inner wall at the upper end. Further, the rotation stopper engagement rod 4 is inserted into a threaded cylinder 7 having a rotation stopper engagement hole 16 having a hexagonal cross section, and is engaged to make the screw cylinder 7 slidable and unrotatable. There is. A right upward spiral groove 5 and a left upward spiral groove 6 are spirally provided on the outer wall of the threaded cylinder 7. Among these, the upper right spiral groove 5 has the middle cylinder 11
The screw pieces 10 are screwed together.

The middle cylinder 11 is inserted and fixed from the lower end of the sleeve 9. This sleeve 9 has an engagement groove 15 formed in the side wall in the vertical direction. Moreover, an inner plate 12 for holding a cosmetic stick is slidably housed inside the sleeve 9. A cut leg tube 13 hangs down from this inner plate 12. An engagement protrusion 14 is protruded from the outer wall of the lower end of the leg tube 13, and the engagement protrusion 14 engages with the engagement groove 15 of the sleeve 9, making the inner plate 12 unrotatable. I have to. Further, on the inner wall of the lower end of the leg tube 13, a threaded engagement piece 10' that is threadedly engaged with the left upward spiral groove 6 of the threaded tube 7 is provided protrudingly.

Note that the leg tube 13 and the middle tube 11 are configured so that when the leg tube 13 descends inside the sleeve 9, the leg tube 13 enters into the cut portion 17 of the middle tube 11. In addition, the length a of the threaded part of the middle cylinder 11 and the leg cylinder 13 is determined by the width of each spiral groove so that it does not enter the opposite side at the intersection of the right-up spiral groove 5 and the left-up spiral groove 6 of the threaded cylinder 7. It is necessary to configure it to be longer than b.

[Effect of idea]

The present invention is the above-described dispensed cosmetic stick container, in which the threaded cylinder 7 is threaded with an intersecting spiral, the threaded cylinder 7 itself is raised by one spiral groove, and the leg cylinder 13 hanging down from the inner plate 12 is attached to the other side. It is designed to be raised by threading it into a spiral groove.

That is, one threaded tube 7 performs two screwing operations, only one rotation prevention mechanism is required for the threaded tube 7 itself, and a dispensed cosmetic stick container is provided that has a small diameter and can have a long dispensing stroke. It is something.

Incidentally, since the length a of the threaded engagement pieces 10 and 10' is longer than the width b of the spiral groove, there is no possibility that the engagement pieces 10 and 10' will intrude into the other spiral groove at the intersection of the spiral grooves.
