Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a container for dispensing stick-shaped cosmetics such as lipstick, and more specifically, a container for dispensing a suitable amount of cosmetics using a combination of a knob dispensing mechanism and a rotary dispensing mechanism. Regarding containers.

[Conventional technology]

BACKGROUND ART Many proposals have been made in the past as containers for dispensing stick-shaped cosmetic pencil leads using a knocking method or containers using a rotating method, including one made by the applicant of the present invention. One of the technical problems common to both the knock-out and rotary-feeding methods is that when the core that has been fed out is pushed back into the container body or cartridge, the core may break or be pushed. There is a problem with it being crushed. This problem is particularly noticeable in the case of cosmetics with soft cores.

For example, the goal of solving this problem is the 10th
There is a knock type rod-shaped cosmetic dispensing container described in Japanese Patent Application Laid-Open No. 58-67207 as shown in FIGS. 58 and 11. In the case of this dispensing container, after the rod-shaped cosmetic 1 that is the core is dispensed and used, it is stored in the container main body side again by the knock operation without touching the cosmetic 1, and as a result, when it is returned as before, It is said that it is possible to eliminate problems caused by the cosmetic material 1 being bent or crushed due to the pushing force of the cosmetic material 1.

That is, the general structure of this dispensing container is such that a cartridge 2, which dispenses the cosmetic 1 from its tip, is detachably attached to a shaft cylinder 3 of the container body. From the state shown in FIG. 9, which shows the cross section containing the cosmetic 1, the rear push pipe 4
When the cosmetic material 1 is pushed into the shaft cylinder 3 by a click operation, it is pushed out by the push shaft 5 moving in the axial direction, and a predetermined amount of the cosmetic material 1 is drawn out from the tip of the cartridge 2.

After use, when putting the cosmetic 1 back into the cartridge 2, push the push button 6 that protrudes from the barrel surface of the barrel 3 so that it can freely move in and out. The biasing force is released,
By returning and retreating the feeding mechanism to the normal position, the cosmetic 1 is pulled back by the amount of the retreat.

[Problem that the invention attempts to solve]

However, in the case of this dispensing container, the push button 6
The return amount of the cosmetic 1 due to the operation is uniformly determined by the feed stroke L of the sliding tube 7. As a result, if an excessive amount of the cosmetic 1 is dispensed from the cartridge 2 due to several careless notch dispensing operations at the beginning of dispensing, it is difficult to restore the amount to a suitable amount for use, or to correct the excessive dispensing amount. When using it as is and then returning it, the amount of cosmetic 1 returned is naturally determined by the amount of 1 that is returned by pressing the push button 6.
It is only for the stroke L. Therefore, in many cases, a portion of the cosmetic 1 that cannot be accommodated will remain outside the cartridge 2. However,
With this feeding container mechanism, there is no way to completely accommodate this unaccommodated portion, and the cosmetic
There is a problem in the past that it is necessary to forcefully push the cartridge into the cartridge 2, and if the unaccommodated portion is left and stored until the next use, there are hygiene problems.

The present invention was made to solve the problems of the conventional methods, and it makes it easy to dispense the desired amount of cosmetics and the amount suitable for use, and makes it easier to dispense cosmetics inadvertently or intentionally. To enable the excess amount to be accurately returned even when an excessive amount of cosmetic is initially fed out, and to ensure that the rod-shaped cosmetic is always supported with substantially constant elasticity when the rod-shaped cosmetic is used. The purpose is to provide a container for dispensing bar-shaped cosmetics.

[Means for solving problems]

In order to achieve this objective, the stick-shaped cosmetic dispensing container according to the present invention has the following configuration.

That is, in this dispensing container, the cylindrical sleeve 12 protruding forward from within the cylindrical body 10 is relatively rotatable around the longitudinal axis within the cylindrical body 10, and
In the axial direction, the cylinder body 1 is held back by the return spring 20.
It is relatively slidable while being biased in the direction of protruding outward.

A sliding holder 14 is provided within the sleeve 12 to hold a rod-shaped cosmetic 13, and an extrusion rod 16 is provided which is coupled to the holder 14 and reciprocates on the axis within the cylinder body 10.

Moreover, in the cylinder body 10, by rotating the cylinder body 10 with respect to the sleeve 12, the cosmetic material 10 can be removed.
A rotary feeding mechanism is incorporated to linearly move the extrusion rod 16 so that the rod 3 can be fed out or drawn in to a desired length.

Further, inside the cylinder body 10, there is a sleeve 12.
A knock-out mechanism is provided for linearly moving the extrusion rod 16 so that the cosmetic material 13 is fed out or drawn in by a predetermined length L by a push-knocking operation on the cylinder body 10.

Here, as the rotational feeding mechanism, a spiral tube 22 is fitted into the tube body 10, a vertical groove 22c is provided on the outer periphery of the spiral tube 22, and the groove 22c is provided in the outer circumference of the spiral tube 22.
The sliding protrusion 11b provided in the longitudinal direction of the inner circumferential surface of the inner cylinder member 11 is fitted into c, so that the spiral cylinder 22 is slidable within the cylinder body 10, and the spiral cylinder 22 and the cylinder body are connected. 10 is fitted so as to be able to rotate integrally around an axis, and a threaded protrusion 16a provided at the rear end of the extrusion rod 16 is screwed into a spiral groove 22a provided on the inner circumferential surface of the spiral tube 22. ing. By this,
The extrusion rod 16 is movable in forward and backward directions by the propulsive force generated by the integral rotation of the cylinder body 10 and the spiral cylinder 22. These extrusion rods 16 and spiral tubes 22
The pushing rod 16 is biased by the biasing spring 23 so that both members integrally move from the return home position in the forward direction.
And the spiral tube 22 can be moved forward and backward within the distance of the predetermined length L.

On the other hand, the above-mentioned knock-out mechanism is provided with a cam-clutch section C which is switched and activated by the knocking operation of the sleeve 12, and the operation of this cam-clutch section C causes the push-out rod 16 and The forward movement prevention means for the spiral tube 22 is released and the biasing spring 2 is released.
3 to advance the predetermined length L, and to move the same distance L back to the home position against the biasing spring 23.

[Effect]

When the cosmetic 13 is initially used and the cosmetic 13 is dispensed in an amount equivalent to a predetermined length L, the sleeve 1
2 into the cylinder body 10 and perform the knotting operation. This knocking operation switches and activates the cam clutch portion C in the knocking mechanism, releases the clutch of the blocking means, and advances the extrusion rod 16 and helical tube 22 together by the urging force of the urging spring 23. By moving forward by a predetermined length L of 16, the holder 14
The upper cosmetic material 13 is made to protrude by a predetermined length L from the tip of the sleeve 12.

After dispensing this initial amount, if it is desired to further dispensing or dispensing an arbitrary amount of the cosmetic material 13, the cylinder body 10 and the sleeve 12 are rotated in a relative direction to each other, and the spiral cylinder on the rotation dispensing mechanism side is rotated. 22 rotates together with the cylinder main body 22, and the extrusion rod 6 receives a propulsive force and moves on the axis by a distance commensurate with the amount of rotation of the spiral cylinder 22. That is, the desired amount of the cosmetic 13 on the holder 14 is fed out or fed in.

Here, if the knocking operation is performed again without operating the rotational feeding mechanism after the initial amount has been fed out as described above, the cam clutch section C is switched, and the cam clutch part C is switched, and The extrusion rod 6 and the spiral tube 22 integrally return to their normal positions by a predetermined length L that is the same as the forward distance.
The cosmetic material 13 on the holder 14 is drawn in and housed in the sleeve 12.

Since the cosmetics 13 are fed out one after another as described above, when the cosmetics 13 are used and become short, the extrusion rod 16 is fed out, the helical tube 22 does not move forward, and the biasing spring 23 does not extend. The biasing spring 23 always maintains a substantially constant biasing force.

Therefore, when the cosmetic 13 is pressed against the application area for makeup, the cosmetic 13 is always supported with a substantially constant elasticity regardless of its length.

〔Example〕

EMBODIMENT OF THE INVENTION Hereinafter, one embodiment of the dispenser for a bar-shaped cosmetic according to the present invention will be described with reference to the drawings.

1 to 9, an inner cylindrical member 11 is integrally fixed and fitted on the inner circumferential surface of the cylindrical body 10 of the container with a portion protruding from the tip. A long sleeve 1 protrudes forward from the
2 is slidably fitted. A rod-shaped cosmetic 13 such as lipstick is accommodated in the sleeve 12 so as to be freely drawn out and retracted, and this cosmetic 13 is supported by a holder 14 so that it can be moved within the sleeve 12.

A rod guide portion 1 is provided on the rear inner peripheral surface of the sleeve 12.
5 are integrally fixed and fitted, and the extruded rod 16 is inserted into the rod guide cylinder 15 and is inserted into the cylinder body 10.
It is movable along the inner longitudinal axis in the left and right directions in the figure. This pushing rod 16 serves as a transmission member for both the rotary feeding mechanism and the knock feeding mechanism. The extruded rod 16 is formed into a long spline shaft with a large number of grooves formed in the longitudinal direction of its circumference, and is slidably fitted into a spline groove 15a provided in the rod guide cylinder 15.
Movement in the axial direction is free, but rotation around the axis is prevented. The tip of this extrusion rod 16 is connected to the holder 14,
The reciprocating motion on the axis brings the holder 14 together and the cosmetic 1
It is transmitted as 3.

Here, the configuration of the rotational feeding mechanism is as follows:
A spiral tube 22 is fitted inside, a slide step 22b is provided on the outer periphery of the spiral tube 22, and a vertical groove 22c is provided in the slide step 22b.
2c is fitted with a sliding protrusion 11b provided in the longitudinal direction of the inner circumferential surface of the inner cylinder member 11, so that the spiral cylinder 22 is slidably movable within the cylinder body 10, and the spiral cylinder 22 and the cylinder body are connected. 10 can rotate integrally around an axis.

Further, a spiral groove 22a is formed on the inner circumferential surface of the spiral tube 22 almost completely in the longitudinal direction. It matches. That is, by rotating the helical tube 22, the extrusion rod 16
A propulsive force is applied to the , which moves the axial line in forward and backward directions.

Further, the extrusion rod 16 and the spiral tube 22 are integrally urged in the forward direction to the left in the figure by the urging spring 23 of the spring member. It is positioned at a predetermined position, and when this positioning means is released, the biasing spring 23 causes it to jump out a distance of the predetermined length L mentioned above and move forward.

On the other hand, the structure of the notch feeding mechanism is such that a plurality of fixed cam protrusions 15b are formed at equal intervals around the rear end of the rod guide cylinder 15.
b constitutes a cam clutch portion C together with another cam cylinder 17 and rotating cam 21.

As shown in FIG. 6, a plurality of deep grooves 17a, protrusions 17b, shallow grooves 17c, and protrusions 17b are formed in this order on the inner peripheral surface of the cam cylinder 17.
The tip portion from b to the shallow groove 17c is a protrusion 17.
It forms an inclined stepped portion 17d which is inclined from b to the shallow groove 17c side. Fixed cam protrusions 15b are provided corresponding to the deep grooves 17a and shallow grooves 17c, respectively, and are slidably engaged in the corresponding deep grooves 17a and shallow grooves 17c. In addition, fixed cam protrusion 1
The tip end surface of 5b is an inclined surface inclined in the same direction as the inclined step portion 17d.

An annular engagement projection 11 a provided on the inner circumferential surface of the internal member 11 on the cylinder body 10 side is engaged with a locking groove 18 provided annularly on the outer periphery of the cam cylinder 17 . As a result, the cam cylinder 17 slides on the inner circumferential surface of the inner cylinder member 11 and can freely rotate around the axis, but is fitted in such a manner that linear movement in the axial direction is prevented.
A return spring 20 is provided between the cam cylinder 17 and the rod guide cylinder 15, which are prevented from moving in the axial direction.
is interposed, and the return spring 20 urges the rod guide cylinder 15 to return to its normal position forward in the left direction in the figure. In other words, the sleeve 12 integrally connected to the rod guide cylinder 15 is attached to the inner cylinder member 11.
It is biased to protrude outward to the left.

Moreover, inside the cam cylinder 17, the rod indoor cylinder 1
5 fixed cam protrusion 15b and annular rotating cam 21
The rotary cam protrusions 21a are arranged facing each other, and the rotary cam protrusions 21a are provided corresponding only to the deep grooves 17a, so that they can freely slide into the deep grooves 17a and can be freely removed from the tips of the deep grooves 17a. Further, the end surface of the rotating cam projection 21a on the fixed cam projection 15b side is an inclined surface in the same direction as the inclined stepped portion 17d. The cam clutch portion C is formed by each of the above members.

The front end surface of the helical tube 22 on the rotary feeding mechanism side comes into contact with the rotary cam 21 of the cam clutch portion C, so that the helical tube 22 and the extrusion rod 1
6 are pushed out together from the rear by a biasing spring 23 and are prevented from moving forward. That is,
The rotating cam 21 serves as a means for preventing the extrusion rod 16 and the spiral tube 22 from moving forward together by a predetermined length L, in other words, it serves as a positioning member for returning both members to their normal positions.

Next, the function and operation mode of the embodiment will be explained.

The operation for dispensing the initial amount of the first cosmetic product is performed in the first step.
Remove the cap 30 from the state shown in Fig. 7,
The outer cylinder 10 is grasped and the sleeve 12 is pushed inward against the return spring 20 (knocking). However, if the notching operation is interrupted and the pushing is released, the sleeve 12 will release the return spring 20.
The robot moves forward again to the original steady position shown in FIG.

In the initial state shown in FIG.
a comes out of the deep groove 17a and is caught on the inclined step portion 17d at the tip of the shallow groove 17c, and is urged toward the fixed cam protrusion 15b by the urging force of the urging spring 23.

By the knotting operation of the sleeve 12, the rod guide cylinder 15 moves to the right in the figure, and the shallow groove 17c
The inner fixed cam protrusion 15b abuts against the rotary cam protrusion 21a, and the rotary cam protrusion 21a (rotary cam 21) is moved back against the biasing spring 23 via the spiral tube 22 whose tip is in contact with the rotary cam 21. . Then, the rotating cam protrusion 21a is connected to the cam cylinder 17.
The biasing spring 23 comes off the inclined stepped portion 17d of the
The rotating cam 2 slides on the inclined surface of the fixed cam protrusion 15b due to the urging force of the fixed cam protrusion 15b, and is rotated and engaged in the adjacent deep groove 17a.
1. The spiral tube 22 is urged by the urging spring 23 and slides forward by a predetermined length L. As a result, the extrusion rods 16 also move forward by the same distance L, and the cosmetic material 13 on the holder 14 is dispensed from the sleeve 12 as an initial amount (second
(Fig. 8).

On the other hand, when such an initial rollout is performed,
Although this dispensed amount does not pose a problem when using cosmetics, if it is desired to dispense an arbitrary amount of the cosmetic 13, the rotating dispensing mechanism is used for dispensing operation.

That is, this time, while gripping the sleeve 2, the tube body 10 is relatively rotated in a predetermined direction, and the internal spiral tube 22 is rotated together with this tube body 10. Since the extrusion rod 16 is prevented from rotating around the axis via the rod guide tube 15 by gripping and fixing the sleeve 12, the rotation of the helical tube 22 is converted into a linear motion of the extrusion rod 16 in the axial direction, and the extrusion rod 16 is rotated in a spiral direction. It moves forward by an arbitrary length distance corresponding to the amount of rotation of the cylinder 22.

To store the cosmetic 13, when the cylinder body 10 is relatively rotated in the opposite direction, the amount of the cosmetic 13 corresponding to the reverse rotation is returned into the sleeve 12 due to the relationship between the extrusion rod 16 and the spiral cylinder 22. . However, at this time, instead of using the rotational feeding mechanism to perform feeding and feeding, these operations can also be performed by the knock feeding mechanism.

That is, as shown in FIGS. 2 and 8, after using the initial amount delivered by one knotting operation, when the cylinder body 10 is gripped and fixed and the sleeve 12 is knotted again, the predetermined length is extended until then. L
The helical tube 22, which had moved forward by a distance of Once pushed back. At this time, the rotating cam protrusion 21a is in the deep groove 17a.
Pushed by the inner fixed cam protrusion 15b, when it exits the deep groove 17a, a rotating force is applied by the biasing force of the biasing spring 23 on the inclined surface of the tip of the fixed cam protrusion 15b, and the adjacent shallow groove with the protrusion 17b in between is applied. 17c
It moves to the side and gets caught on the inclined step part 17d again,
It is fixed in the state shown in FIG. By fixing the rotary cam 21, the retracted spiral cylinder 22 remains at its return home position and is prevented from moving forward. As the helical tube 22 retreats, the extrusion rod 16 itself also retreats by the same distance, and the cosmetic material 13 on the holder 14 is transferred to the sleeve 12.
be carried within.

In addition, when the cosmetic material 13 is fed out and fed in by operating the knock feeding mechanism, it may not necessarily be flush with the tip of the sleeve 12 depending on the consumption amount of the cosmetic material 13 at that time. As a countermeasure for such a case, the cosmetic material 13 is completely accommodated in the sleeve 12 by finely adjusting the rotary delivery mechanism as described above, so that there is no excess or deficiency.

[Effect of idea]

As explained above, the bar-shaped cosmetic dispensing container according to the present invention is equipped with a rotary dispensing mechanism and a knock dispensing mechanism, and the cam clutch section C interposed between these mechanisms allows one of the two mechanisms to be moved from one side to the other. By switching the transmission to and using both mechanisms properly each time, the cosmetics 13 can be quickly and accurately fed out and put in just the right amount.

In other words, the cosmetic 1 that is intentionally or carelessly dispensed excessively as in the case of conventional dispensing containers of this type.
This solves the problem of the extremely troublesome re-operation to adjust the amount of 3 to the appropriate amount, and the fine adjustment is easy to use and highly practical.

In the present invention, the helical tube 22 is biased forward by a biasing spring 23, and the extrusion rod 16 is screwed into the helical tube 22.

Then, when the cosmetic material 13 is used and the length becomes shorter,
The extrusion rod 16 is fed out, and the helical tube 2
2 does not move forward, and the biasing spring 23 does not extend and always maintains a substantially constant biasing force.

Therefore, when the cosmetic 13 is pressed against the application area in order to hold the cosmetic 13, even if the cosmetic 13 is short, the biasing spring 23 always keeps the cosmetic 13 at a substantially constant level. It is supported with elasticity and makes it easy to apply makeup.
