BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stick-out cosmetics container for storing stick-shaped cosmetics such as lipsticks and eye shadows, which prevents accidental stick-out of stick-shaped cosmetics.

[0002]

2. Description of the Related Art Conventionally, a container for storing a stick-shaped cosmetic material such as lipstick and eye shadow has a holding cylinder in which the stick-shaped cosmetic material is fitted and held, and the holding cylinder is guided so as to be non-rotatably slidable up and down. The spiral feeding mechanism, which is composed of a member having a guide groove engraved therein and a member having a spiral groove into which the holding cylinder is screwed, is internally provided, and the member engraved with the guide groove and the spiral groove are screwed together. The holding cylinder is slid up and down by a screwing action by rotating the provided member relatively. Then, a sleeve, an outer cylinder, and the like, which are exterior bodies, are fixed to the spiral feeding mechanism,
It constituted a stick-shaped cosmetics feeding container.

[0003]

However, when a stick-shaped cosmetic container of this kind is carried in a handbag or the like and is carried, the stick-shaped cosmetic container is not vibrated or impacted with the dispensing opening facing downward. There was a possibility to join. In this case, due to the impact and vibration, and the weight of the stick cosmetic,
When the cap is fitted, the spiral feeding mechanism is activated to feed the stick-shaped cosmetic, and the tip of the stick-shaped cosmetic may be damaged.

[0004] Further, when producing a stick-shaped cosmetic feed container, after assembling the container in a container assembly factory, it is transported to a stick-shaped cosmetic filling factory and filled with the stick-shaped cosmetic. In order to easily fill the stick-shaped cosmetics at the stick-shaped cosmetic filling factory, the stick-shaped cosmetic feeding container was shipped in a state of being pushed up to the top dead center. Therefore, there is a risk that the elevating cylinder on which the stick-shaped cosmetic material is mounted may be lowered due to vibration during transportation and the filling may not be possible when the stick-shaped cosmetic material is filled.

[0005]

Means for Solving the Problems An elevating cylinder 2 in which a stick-shaped cosmetic material 1 is fitted and held has a screwing piece 6 protruding from a side wall. A leg cylinder 3 is hung at the lower end of the elevating cylinder 2, and a side wall of the leg cylinder 3 is provided with an inwardly elastic and bendable sensitive protrusion 4.
The screwing piece 6 and the sensitive protrusion 4 are arranged parallel to the axis.
The elevating cylinder 2 is installed inside the guide cylinder 7 so as to be vertically slidable. On the side wall of the guide cylinder 7, there is provided a guide groove 8 which extends through the screwing piece 6 of the elevating cylinder 2 and guides the elevating cylinder 2 so as to be non-rotatably vertically slidable, and which is horizontal at the upper and lower ends. Part 9,
10 is provided and drilled. Below this upper horizontal part 9,
When the screwing piece 6 of the elevating cylinder 2 comes into contact with the end of the horizontal portion 9, an engaging hole 11 with which the sensitive protrusion 4 is engaged is formed. Guide groove 8
On the inner wall of the lower end, there is provided a protrusion groove 12 into which the sensitive protrusion 4 protrudes when the screwing piece 6 abuts on the lower end of the guide groove 8.
On the lower inner wall of 0, an engaging groove 13 into which the sensitive protrusion 4 is inserted when the screwing piece 6 is brought into contact with the end of the lower horizontal portion 10 is formed in parallel with the above-mentioned protrusion groove 12. Below the guide groove 8, a holding portion 15 holding a sliding contact ring 18 having an enlarged outer diameter and elasticity is provided, and below the holding portion 15, a base portion 16 having an even larger outer diameter is provided. This guide cylinder 7 is a spiral cylinder 19
Is rotatably held so as not to fall off. On the inner wall of the spiral cylinder 19, a spiral groove 22 into which the screwing piece 6 of the elevating cylinder 2 is screwed.
Screw. At the lower end of the spiral cylinder 19, a holding portion 15 of the guide cylinder 7 is covered, and a sliding contact portion 21 with which the sliding contact ring 18 has elastic contact with the inner wall is provided.

[0006]

When the spiral cylinder 19 and the base 16 of the guide cylinder 7 are held and the spiral cylinder 19 and the guide cylinder 7 are rotated relative to each other, the lifting cylinder 2 in which the screwing piece 6 penetrates the guide groove 8 of the guide cylinder 7 also spirals. It rotates relative to the cylinder 19. As a result, since the screwing piece 6 of the elevating barrel 2 is screwed into the spiral groove 22 of the spiral barrel 19 that rotates relative to each other, a screwing action occurs, and the elevating barrel 2 and the bar-shaped cosmetic 1 move up and down. When the spiral cylinder 19 and the guide cylinder 7 rotate relative to each other, the sliding contact ring 18 fitted to the holding portion 15 of the guide cylinder 7 elastically and slidably contacts the guide cylinder 7 and the spiral cylinder 19, respectively. Therefore, sliding resistance occurs. This sliding resistance makes the operation feeling good during the rotating operation.

Further, the elevating cylinder 2 is at the bottom dead center, that is, the screwing piece 6
Is in contact with the end of the lower horizontal portion 10 of the guide groove 8, the sensitive protrusion 4 projects into the engaging groove 13 formed in the inner wall of the guide cylinder 7. Here, when you perform the feeding operation,
The screwing piece 6 of the elevating cylinder 2 projects into the guide groove 8 from the horizontal portion 10, and the elevating cylinder 2 moves up and down. At the same time, the sensitive protrusion 4 comes out of the engagement groove 13, rides over the inner wall of the guide cylinder 7, and enters the protrusion groove 12. Further, when the elevating cylinder 2 rises, the sensing protrusion 4 also protrudes into the guide groove 8 from the protrusion groove 12 and rises along the guide groove 8 so that the screwing piece 6 rises in the guide groove 8. Then, when the elevating cylinder 2 reaches the top dead center, the screwing piece 6 projects into the upper horizontal portion 9. At the same time, the sensitive protrusion 4 comes out of the guide groove 8, goes over the inner wall of the guide cylinder 7, and is inserted into the engaging hole 11 and is engaged therewith. Therefore, the elevating cylinder 2 rises,
That is, in order for the screwing piece 6 to project into the guide groove 8 bored in the axial direction, it is necessary for the sensitive protrusion 4 to ride over the inner wall of the guide cylinder 7, and this climbing resistance causes the lifting cylinder 2 to engage at the top and bottom dead center. It is supposed to stop.

[0008]

EXAMPLE An elevating cylinder 2 in which a stick-shaped cosmetic material 1 such as lipstick and eye shadow is fitted and held has a leg cylinder 3 hung at its lower end. On the outer side wall of the leg cylinder 3, a pair of sensitive protrusions 4 are provided at opposite positions. A pair of notches 5 is provided from the lower end on both sides of the sensitive protrusion 4, and the sensitive protrusion 4 is configured to be elastically bendable inward. Further, on the outer wall of the elevating cylinder 2, a pair of screwing pieces 6 are projected at opposite positions. The screwing piece 6 and the sensitive protrusion 4 are arranged vertically in parallel with the axis.

The elevating cylinder 2 is mounted inside a guide cylinder 7 so as to be vertically slidable. On the side wall of the guide cylinder 7, a pair of guide grooves 8 through which the screwing piece 6 of the elevating cylinder 2 penetrates and the sensitive protrusion 4 engages are formed at opposite positions in the axial direction long. Horizontal portions 9 and 10 into which the screwing pieces 6 project when the elevating cylinder 2 is at the top dead center or the bottom dead center are continuously provided at the upper end and the lower end of the guide groove 8. Further, below the tip of the horizontal portion 9 on the upper end side, there is an engagement hole 11 with which the sensitive protrusion 4 engages in a state where the screwing piece 6 of the elevating cylinder 2 is in contact with the tip of the horizontal portion 9 on the upper end side. Has been drilled. Further, from the lower end of the guide groove 8, a thrust groove 12 into which the sensitive protrusion 4 is thrust when the elevating cylinder 2 is positioned at the bottom dead center is carved in series with the guide groove 8 on the inner wall. Further, an engaging groove 13 is formed in parallel with the protrusion groove 12 on the lower inner wall at the tip of the horizontal portion 10 on the lower end side. Since the sensitive protrusion 4 is configured to be elastic and bendable inward, the guide groove 8 or the thrust groove 1 is formed.
2, it is possible to ride over the inner wall of the guide cylinder 7 and engage with the engagement hole 11 or the engagement groove 13.

An engagement rib 14 projects from the upper end of the guide cylinder 7 in the outer peripheral direction. Further, below the lower horizontal portion 10, the outer diameter is enlarged to form a holding portion 15. Below the holding portion 15, the outer diameter is further enlarged to form a base portion 16. A fitting groove 17 is formed on the side wall of the holding portion 15. A sliding contact ring 18 having elasticity such as an O-ring is fitted in the fitting groove 17.

Further, the guide cylinder 7 has a spiral cylinder 19 on the outer circumference.
Is rotatably held. The upper end of this spiral tube 19
The inner diameter is enlarged to form an engaging portion 20 with which the engaging rib 14 of the guide cylinder 7 is engaged. Similarly, the lower end of the spiral cylinder 19 has an enlarged inner diameter to form a sliding contact portion 21 that covers the holding portion 15 of the spiral cylinder 19. The spiral cylinder 19 is the guide cylinder 7.
It is rotatably held between the engaging rib 14 and the holding portion 15 so as not to fall off. In addition, a sliding contact ring 18 fitted in the fitting groove 17 of the guide cylinder 7 has elasticity and slidably contacts the sliding contact portion 21 at the bottom of the spiral cylinder 19. As a result, when the guide cylinder 7 and the spiral cylinder 19 are rotated relative to each other, sliding resistance is generated by the sliding contact ring 18 that is in sliding contact with each other. This sliding resistance improves the feel of the stick-shaped cosmetic material 1 when it is drawn out. Further, between the engaging rib 14 on the inner wall of the spiral cylinder 19 and the sliding contact portion 21, a spiral groove 22 into which the screwing piece 6 of the elevating cylinder 2 that penetrates the guide groove 8 of the guide cylinder 7 is screwed is provided. Has been done.

A cap 23 fitted on the spiral cylinder 19
Has a fitting portion 24 that hangs from the ceiling surface, and the fitting portion 24 is fitted in the upper end of the guide cylinder 7 in a protruding manner.

[0013]

As described above, according to the present invention, in addition to the screwing piece 6 that is screwed into the spiral groove 22 to move the elevating cylinder 2 up and down, the sensitive protrusion 4 is connected to the screwing piece 6 by an axis line. Place them in parallel,
The horizontal portions 9 and 10 into which the screwing pieces 6 project at the top dead center and the bottom dead center of the elevating cylinder 2 are provided, and an engaging hole 11 is provided below the upper horizontal portion 9 and an engaging hole 11 is provided below the lower horizontal portion 10. Grooves 13 are provided respectively, and the elevating cylinder 2 is configured to engage the sensitive protrusions 4 at the top dead center and the bottom dead center positions. The guide groove 8 is provided with the inrush groove 12 parallel to the engaging groove 13. are doing. Therefore, when the screwing piece 6 projects into the guide groove 8 and the up-and-down cylinder 2 slides up and down, the sensitive protrusion 4 moves in the guide groove 8 and the projecting groove 12, and the screwing piece 6 moves. When it enters the horizontal portions 9 and 10 from 8, the sensitive protrusion 4 comes out of the guide groove 8 or the protrusion groove 12, gets over the inner wall of the guide cylinder 7 and engages with the engagement groove 13 or the engagement hole 11. ing. That is, the sensitive protrusion 4 is engaged with the engaging groove 13 or the engaging hole 11 at the top-bottom dead center of the elevating cylinder 2, and the sensitive protrusion 4 is engaged with the engaging groove 13.
Alternatively, the elevating cylinder 2 is prevented from sliding up and down unless a stress for escaping from the engagement hole 11 is exerted. Therefore, if the sensitive protrusion 4 is engaged with the engaging groove 13 or the engaging hole 11, the sliding of the elevating cylinder 2 does not occur unexpectedly. Moreover, since the leg cylinder 3 protruding from the sensitive protrusion 4 is deformed only when getting over the inner wall of the guide cylinder 7, the elasticity of the sensitive protrusion 4 is reduced and the engagement groove 13 and the engagement hole 11 are used for a long period of time. The function of the sensitive protrusion 4 can be maintained semi-permanently without a decrease in the engaging force with.

Further, when the sensitive protrusion 4 crosses over the inner wall of the guide cylinder 7, a crossover resistance is generated.
This overcoming resistance is transmitted to the hand as a feeling during the feeding operation, and the user can be notified as a feeling that the elevating cylinder 2 is locked at the top dead center or the bottom dead center. Therefore,
It is also possible to prevent an accident in which the spiral payout mechanism is damaged due to an excessive force applied to the spiral payout mechanism when the screw is forcibly rotated at the top dead center or the dead center.
