Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a feeding mechanism for a rod-shaped cosmetic container.

[Conventional technology]

Traditionally, it has been possible to reduce the outer diameter of the dispenser-type cosmetic bar container, which has a dispensing mechanism built into the lower part of the cosmetic bar, but the overall length of the container is more than twice the length of the cosmetic bar. Because it is necessary to
If the bar-shaped cosmetic was made longer, the container would also become longer.

Therefore, as seen in Japanese Utility Model Publication No. 52-16932, when the base tube is rotated while holding the sliding tube, the inner plate containing the bar-shaped cosmetic material rises while the bar-shaped cosmetic material is covered. A structure has been proposed in which a sliding tube is lowered to dispense a bar-shaped cosmetic with a length twice the length of the dispensing mechanism.

[Problem that the invention attempts to solve]

However, because the inner wall of the sliding tube has a keyway carved into it to stop the rotation of the inner plate, the thickness of the sliding tube becomes thicker, resulting in an ungainly container. Shimatsuta. In addition, the base cylinder is a double cylinder with a spiral groove threaded on the inner wall and an inner cylinder with a counter-rotating spiral groove threaded on the inner wall.
It had a complex structure and was difficult to manufacture.

[Means for solving problems]

The threaded cylinder 7 is provided with a tail plug part 11 for fixing the base cylinder 10 at the lower end thereof, and a right upward spiral groove 8 and a left upward spiral groove 8' are screwed to intersect with each other on the outer wall thereof.

The leg tube 3 that hangs down from the inner plate 2 that fits and holds the bar-shaped cosmetic 1 has a screwing piece 9' that screws into the left upward spiral groove 8' screwed into the threaded tube 7 at the lower end of the inner wall, and a screwing piece 9' that is screwed into the outer wall. Engagement protrusions 5 are provided protrudingly from the lower ends. Further, an engagement groove 6' is formed in the vertical direction from the lower end.

The sliding tube 4 which slidably accommodates the inner plate 2 and the leg tube 3 passes through the engagement groove 6' of the leg tube 3 at the lower end of the inner wall and is screwed into the right upward spiral groove 8 of the threaded tube 7. A screwing piece 9 is provided protrudingly. Further, an engagement groove 6 into which the engagement protrusion 5 of the leg tube 3 engages is vertically bored from the lower end. The sliding tube 4 is slidably and rotatably inserted into the base tube 10.

The present invention has the above configuration.

[Effect]

When in use, when the base tube 10 is rotated clockwise while holding the sliding tube 4, the screwing piece 9 of the sliding tube 4 passes through the engagement groove 6' of the leg tube 3 and forms the right-up spiral groove 8. Since it is screwed together, the leg tube 3 and the inner plate 2 are lowered while rotating together. At this time, the leg tube 3, which is rotating in conjunction with the sliding tube 4, also moves up because the threaded piece 9' at the lower end is screwed into the left-up spiral groove 8' of the threaded tube 7, and becomes rod-shaped. The cosmetic 1 is dispensed.

Incidentally, when the sliding tube 4 and the leg tube 3 move more than halfway along the threaded tube 7, the threaded piece 9 of the sliding tube 4 escapes from the engagement groove 6' of the leg tube 3. However, since the engagement protrusion 5 of the leg tube 3 engages with the engagement groove 6 of the sliding tube 4 earlier than the escape of the screwing piece 9, the leg tube 3 always rotates together with the sliding tube 4. .

As the rotation continues, the sliding tube 4 comes into contact with the tail plug 11, and the engaging protrusion 5 of the leg tube 3 also comes into contact with the sliding tube 4.
When it comes into contact with the upper end of the engagement groove 6, the feeding operation can no longer be performed, and the respective threaded pieces 9, 9' will not come off from the threaded cylinder 7.

Further, when the base tube 10 is rotated in the opposite direction, the sliding tube 4 rises, and the leg tube 3 descends to lower the bar-shaped cosmetic material 1 and store it in the sliding tube 4.

〔Example〕

An inner plate 2 that accommodates and holds a bar-shaped cosmetic 1 has a leg tube 3 hanging down from its lower end. An engaging protrusion 5 is provided on the outer wall of the lower end of the leg tube 3, and a threaded engagement piece 9' is provided on the inner wall thereof. Further, on the opposite side of the engaging protrusion 5 and the screwing piece 9', an engaging groove 6' is vertically bored above the lower end. And the above medium plate 2
is slidably housed in the sliding tube 4.

The sliding tube 4 has a threaded engagement piece 9 protruding from the inner wall at the lower end that slidably engages with the engagement protrusion 5 of the leg tube 3, and on the opposite side thereof a screw engagement piece 9 that engages vertically upward from the lower end. A matching groove 6 is bored. A threaded piece 9' of the leg tube 3 is slidably passed through the engagement groove 6.

The screw tube 7 inserted from the lower end of the leg tube 3 and the sliding tube 4 has a threaded piece 9 of the sliding tube 4 on the outer wall.
A right upward spiral groove 8 is screwed into the groove. Furthermore, this outer wall is provided with a left-handed spiral groove 8' which intersects with the right-handed spiral groove 8 and into which the threaded engagement piece 9' of the leg tube 3 is screwed. In addition, the length a of each screwing piece 9, 9' is the right upward spiral groove 8 of the threaded cylinder 7.
At the intersection of the upper left spiral groove 8' and the upper left spiral groove 8', the groove is configured to be longer than the spiral groove width b so as to prevent the groove from protruding into the opposite side. A tail plug part 1 is attached to the lower end of the threaded cylinder 7.
1 is provided, and a base cylinder 10 is fixedly attached to this tail plug part 11.

[Effect of idea]

As described above, the present invention provides that even if the two spiral grooves 8, 8' intersecting the outer wall of one threaded cylinder 7 are threaded, the threaded parts of the sliding cylinder 4 and the leg cylinder 3 that are screwed together, respectively. There is no problem with the screwing action of 9 and 9'.
Further, since the threaded cylinder 7 has spiral grooves 8, 8' threaded on its outer wall, it is easy to manufacture.

If the engaging groove 6 is drilled in the sliding tube 4 from the time when the bar-shaped cosmetic 1 is exposed halfway, then the engaging groove 6' drilled in the leg tube 3 will stop the rotation. Therefore, it is not necessary to drill a keyway corresponding to the entire stroke in the sliding tube 4, and the sliding tube 4 can be constructed with a thin wall, making it possible to use a rod-shaped cosmetic container with a thin outer diameter. To provide a payout type cosmetic bar container which can be constructed and has a longer length of the cosmetic bar by one length than the length of the container.
