Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a dispensing container that dispenses bar-shaped cosmetics such as lipstick and is replaceable like a cartridge.

"Prior Art" Conventionally, dispensing containers have been proposed in which rod-shaped cosmetics in the dispensing container are detachably connected and can be replaced in a cartridge type manner. The purpose of this is to use the same dispensing container again by replacing it with another cosmetic bar, and for users, it is an easy way to use the relatively expensive container repeatedly without disposing of it as waste. In addition, for manufacturers, even if cosmetics are damaged during filling, there is no need to dispose of the entire container as a defective product, and the rate of defective products can be reduced. It has advantages such as:

FIG. 14 shows an example of the structure of such a conventional dispensing container (see Utility Model Application Publication No. 51-46571, etc.). This has a helical tube 2 having a helical groove 1 on its inner circumferential surface, a cylindrical portion 3 rotatably supported within the helical tube 2, and a long hole 4 extending along the axial direction on the peripheral wall of the cylindrical portion 3. A cylindrical body 7 that covers the outer periphery of a bar-shaped cosmetic 6 such as a lipstick is formed by the guide cylinder 5 having a guide tube 5 formed therein, and the elongated hole 4 is inserted into the cylindrical body 7 and engaged with the spiral groove 1. A saucer 10 having a protrusion 9 is provided,
The base end of the bar-shaped cosmetic 6 is screwed into the saucer 10 via a holder 11, and the bar-shaped cosmetic 6 is fed out by relative rotation between the spiral tube 2 and the guide tube 5.

"Problems to be solved by the invention" However, in such a conventional dispensing container, the holder 11 is rotated to place the bar-shaped cosmetic 6 into the saucer 10.
On the other hand, since the amount of protrusion T of the holder 11 from the saucer 10 (that is, the length of the upper part of the holder 11 than the male thread 11a) is small, it is difficult to turn the holder 11 when replacing the cosmetic bar 6. Due to these problems, it was difficult to securely tighten the holder 11 to the end. In addition, in order to solve such problems, increasing the protrusion amount T of the holder 11 makes it easier to turn the holder 11, but it has been said that as the protrusion amount T increases, the beauty of the entire dispensing container is impaired. Dissatisfaction arises.

On the other hand, apart from such problems, the holder 11
When using a dispensing container that has a structure in which the cosmetic bar 6 is screwed into the saucer 10, there is a risk that the screw connection may loosen due to the force of pressing the cosmetic bar 6 against the application surface or vibrations when carrying the cosmetic product. At this time, there was a risk that the cosmetic bar 6 would be difficult to use, or that the cosmetic bar 6 would come into contact with the top plate of the cap (not shown) and be damaged.

This invention was made in view of the above circumstances,
The purpose of this is to prevent the holder from detracting from its aesthetic appearance during use due to its large protrusion, to improve operability when replacing bar-shaped cosmetics, and to securely place the holder in the saucer. It is an object of the present invention to provide a dispensing container that can be attached, has an effect of preventing loosening, and can prevent a bar-shaped cosmetic from being damaged.

``Means for Solving the Problems'' The present invention consists of a spiral tube with a spiral groove formed on its inner circumferential surface, and a long hole that is rotatably inserted into the spiral tube and extends in the axial direction in the peripheral wall. a guide tube, a saucer which is inserted into the guide tube so as to be movable up and down and has a protrusion formed on its outer circumferential surface that engages with the spiral groove through the elongated hole, and a base of the bar-shaped cosmetic which is screwed into the tray. The dispensing container is provided with a holder for holding an end thereof, and the holder is connected so as to protrude outward together with the bar-shaped cosmetic material at the highest position of the saucer, and the dispensing container is provided with a holder for holding an end of the container, and the holder is connected to protrude outward together with the bar-shaped cosmetic material at the highest position of the saucer. , an engaging part is provided that engages with a protrusion of the saucer to restrict upward movement of the saucer, and a locking protrusion is provided on one of the inner circumferential surface of the saucer and the outer circumferential surface of the holder, and the engaging protrusion is provided on the other. The locking grooves that engage with the locking protrusions are formed above the female threads of the saucer or the male threads of the holder, and these locking protrusions and grooves are connected to each other at the end point of the holder's spiral movement. It is set to engage.

"Operation" When the spiral cylinder and guide cylinder are rotated relative to each other and the saucer is raised, the protrusion of the saucer rises along the elongated hole.
During its ascent, it is engaged with the engaging portion of the elongated hole, increasing the resistance to rotational operation. By this operation, the holder attached to the saucer and the cosmetic bar are raised together with the saucer, and the cosmetic bar is ready for use with the cosmetic bar protruding outward by the amount of rise of the saucer.

When replacing the holder, move the saucer to its highest position so that the holder protrudes outward, hold the holder in this state, unscrew it from the saucer, and separate the holder from the saucer. Then, when a holder holding a new bar-shaped cosmetic is inserted into the saucer and screwed together, the locking protrusion and the locking groove are engaged at the end point of the screw, and the bar-shaped cosmetic becomes freely retractable. In addition, when the holder is screwed with the saucer, the locking protrusion and the locking groove are engaged, so there is no risk that the screwing between the holder and the saucer will loosen. .

"Embodiment" Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 8.

In these figures, the reference numeral 20 indicates a spiral tube, the reference numeral 21 indicates a guide tube, and the reference numeral 22
What is shown by these spiral tubes 20 and guide tubes 2
The saucer 1 operated by reference numeral 23 is a holder that can be attached to and detached from the saucer 22, and these symbols 20 to 23 constitute the main components of this embodiment.

The spiral tube 20 has a spiral groove 20a formed on its inner circumferential surface, and an engagement step 20b on its upper inner circumferential surface.

On the other hand, the guide tube 21 has a cylindrical shape with a bottom, and a small diameter cylindrical portion 2 fitted into the spiral tube 20 is attached to the upper part of the guide tube 21.
1a, and a circumferential protrusion 21b is formed at the upper end of the small diameter cylindrical portion 21a. By engaging the circumferential protrusion 21b with the engagement stepped portion 20b of the helical tube 20, the spiral It is configured to be rotatably supported by the tube 20.

Further, as shown in FIG. 2, etc., a long hole 24 is formed in the peripheral wall of the small diameter cylindrical portion 21a along the axial direction, and the left side near the upper end of the long hole 24 (left side in FIG. 2) On the periphery, there is a protrusion 22 of the saucer 22.
An engaging portion 25 is formed that engages with a and restricts its upward movement. In the embodiment, the engaging portion 25 is an engaging groove formed in a form that communicates with the long hole 24, and the upper peripheral edge 25a thereof is inclined upward at an angle θ toward the upper side of the long hole 24. The lower peripheral edge 25b is horizontal and intersects the elongated hole 24 at right angles. Moreover, the upper part of this engaging part (hereinafter referred to as an engaging groove) 25, that is, the elongated hole 2
A horizontal groove 26 is formed at the upper end of the groove 4 so as to communicate with the elongated hole 24 and into which the protrusion 22a of the saucer 22 is inserted.

Incidentally, here, the upper peripheral edge 25a of the locking groove 25
The inclination angle θ is determined by the inclination angle θ when the bar-shaped cosmetic 6 is normally used (that is, when the protrusion 22a of the saucer 22 is reciprocated between the lower end of the elongated hole 24 and the engagement groove 25). Protrusion 22a of tray 22
is set at an angle such that it will not rise unless a certain amount of force is applied. In addition, the engagement groove 25 and the lateral groove 2
The distance L between 6 and 6 is set to approximately half the length of the holder 23, and when the saucer 22 moves up this distance L, the upper half of the holder 23 protrudes.

Now, to add an explanation about the saucer 22,
This is formed into a bottomed cylindrical shape having an outer diameter slightly smaller than the inner diameter of the guide cylinder 21 as a whole, and is engaged with the spiral groove 20a through a long hole 24 at opposing positions on the upper part of the outer periphery. A protrusion 22a is provided to protrude. Further, a female thread 22b is formed on the inner peripheral surface of the saucer 22, and this female thread 22b
A locking groove 27 that goes around the circumferential direction is provided at an upper portion.

Further, the holder 23 is formed in a cylindrical shape longer than the length of the saucer 22, and its size is as follows.
The length is set such that at least the upper half of the tray 22 protrudes outward at the highest position. Further, a male thread 23a that is screwed into the female thread 22b of the saucer 22 is formed on the lower outer periphery of this holder 23, and the upper outer periphery (that is, the upper outer periphery than the male thread 23a).
A locking protrusion 28 that engages with the locking groove 27 is provided in a protruding manner. Note that in this embodiment, the saucer 2
The locking groove 27 is formed on the holder 23, and the locking protrusion 28 is formed on the holder 23, but these may be formed on either side.
and the locking protrusion 28 are set to engage with each other at the end point of the spiral movement of the holder 23.

On the other hand, this holder 23 and the bar-shaped cosmetic 6 are
When separated from the saucer 22, it is housed in a capsule 30, as shown in FIG. 5, for example. The capsule 30 is mainly composed of a support plate 31 that vertically supports the bar-shaped cosmetic 6 and a cap 32 that is fitted into the support plate 31.
A female thread 31a is provided to which the male thread 23a of No. 3 is screwed. In addition, in this example, the capsule 30
Although the capsule 30 is configured to accommodate one bar-shaped cosmetic 6, the capsule 30 is not limited to this, and may be configured to accommodate a plurality of bar-shaped cosmetics 6.

In addition, the male screw 23a of the holder 23, the saucer 2
2 female screw 22b and support plate 3 of capsule 30
If each female thread 31a of No. 1 is a multi-thread thread,
This is preferable because the number of rotations when screwing the holder 23 together can be reduced.

Next, the operation of the dispensing container of this embodiment configured as described above will be explained.

When the spiral tube 20 is rotated clockwise in the assembled state as shown in FIGS. 3 and 4,
The spiral groove 20a rotates clockwise and the protrusion 22a of the saucer 22
is pressed, and the saucer 22 is moved upward. By this operation, the holder 23 and the cosmetic bar 6 attached to the saucer 22 are moved upward together with the saucer 22, the cosmetic bar 6 protrudes from the upper end of the spiral tube 20, and the protrusion 22a of the saucer 22 is moved upward. The state inserted into the engagement groove 25, that is, the spiral tube 20
The resistance force against the rotational operation of the tray 22 increases, and the tray 22 is used in a state where its upward movement is restricted.

When the bar-shaped cosmetic 6 is in use, the holder 23 slightly protrudes outward, but since its upper half does not protrude, the beauty of the container as a whole is not impaired. Further, since the locking protrusion 28 of the holder 23 is engaged with the locking groove 27 of the saucer 22, there is no fear that the screwing of the holder 23 will loosen, and the holder 23 can be used in a stable state.

On the other hand, when the spiral tube 20 is rotated counterclockwise, the spiral groove 20a pushes the protrusion 22a of the saucer 22 downward, so that the rod-shaped cosmetic 6 integrally attached to the saucer 22 via the holder 23 returns toward the lower end. and is stored in the guide tube 21.

Next, to explain the case where the bar-shaped cosmetic 6 is replaced, the protrusion 22a of the saucer 22 is inserted into the engagement groove 25.
The helical tube 20 is further rotated clockwise against the resistance force against the rotation operation of the helical tube 20. By this operation, the protrusion 22a is moved into the engagement groove 25.
It rises by a length L along the upper peripheral edge 25a as shown by the arrow in FIG. 2, and is inserted into the horizontal groove 26 at the upper end of the elongated hole 24, so that the upper half of the holder 23 is held in a protruding state.

Then, hold the protruding part of the holder 23 between your fingers and turn it to separate the holder 23 from the saucer 22. In this state, as shown in FIGS. 5 to 7, another bar-shaped cosmetic 6 is inserted into the capsule 30. If the bar-shaped cosmetic 6 is taken out from the container and placed in the tray 22 along with the holder 23, the bar-shaped cosmetic 6 can be retracted and retracted. In addition,
Adding an explanation to the operation of mounting the holder 23, this operation involves inserting the holder 23 into the saucer 22 and turning it in the tightening direction. By this operation, the saucer 22 is screwed forward, and at the end of the screw movement, the locking protrusion 28 and the locking groove 27 engage with each other, and the upward movement of the holder 23 is held in a restricted state. Ru. Further, during this operation, since the locking protrusion 28 and the locking groove 27 are located above the male thread 23a and the female thread 22b, respectively, the holder 2 can be visually inspected.
3 can be confirmed, and the engagement between the locking protrusion 28 and the locking groove 27 can be performed reliably. That is, the locking protrusion 28 is connected to the external thread 23a of the holder 23.
Since the locking protrusion 28 is located above the saucer 22
When the locking protrusion 28 is screwed into the male thread 23a,
Since the holder 23 will be inserted into and engaged with the tray 22 later than the above, while watching the progress of the holder 23,
The engagement of the engagement protrusion 28 can be confirmed. Therefore, in addition to feeling a sense of resistance when the locking protrusion 28 engages with the locking groove 27, the engagement can be confirmed, making it easier to use.

Note that the cut-off bar-shaped cosmetic 6 is stored in a capsule 30 as shown in FIG. In addition, the bar-shaped cosmetic 6 is manufactured by, for example, a so-called back-filling method using a filled capsule.
Other manufacturing methods may also be used.

FIG. 9 shows another embodiment of the present invention, in which the saucer 22 is improved. That is,
This is a split groove 3 that starts from the upper end of the saucer 22.
A locking protrusion 28 is provided on the upper part of the peripheral wall of the saucer 22 divided by the groove 35, and the saucer 2
A locking groove 27 is formed on the outer periphery of a holder 23 that is screwed into the holder 2. In addition, in this way, the saucer 22
When the groove 35 is formed in the groove 35, the tray 22 itself is set so as to protrude outward together with the holder 23 at its highest position. In the dispensing container configured as described above, when replacing the bar-shaped cosmetic 6, the saucer 22 can be made to protrude and its peripheral wall can be made elastic, so that the holder 23 can be easily attached and detached. In addition, during normal use, the receiving tray 22 is prevented from elastically deforming outward by the inner circumferential wall of the guide tube 21, so that the engagement between the locking groove 27 and the locking protrusion 28 is firmly maintained. This allows the locking effect to be exerted.

Note that FIG. 10 shows another embodiment,
An outer cylinder 40 is inserted into the outer periphery of the spiral cylinder 20, a bottomed decorative cylinder 42 is fitted to the outer periphery of the guide cylinder 21 via a connecting cylinder 41, and a decorated cap 43 is attached. Even with such a configuration, there is no change in the function of the dispensing container, and the overall appearance of the container can be improved and the container can be made more luxurious.

Further, another embodiment of the present invention will be explained with reference to FIG. 11. This is basically the same as the above-mentioned embodiment, but is the first embodiment in that the shapes of the spiral tube, guide tube, and saucer are changed. This example is different from that of the previous example. That is, the dispensing container of this embodiment includes a spiral tube 50 having a bottomed cylindrical shape having a spiral groove 50a, and a long hole 2 in the lower half of the spiral tube 50, which is longer than the spiral tube 50.
4 and a saucer 52 having a length corresponding to the length of the guide barrel 51, and a bar-shaped cosmetic 6 is attached to the saucer 52 via a holder 23. Even with such a configuration, the same effects as those of the above-mentioned embodiments can be achieved. In this way, in this invention,
The shape is not limited to the spiral tube, guide tube, saucer, etc.

Moreover, FIG. 12 shows a modification of the locking part 25, in which a horizontal groove 60 is formed in the upper part of the elongated hole 24, and a vertical groove 61 is provided that extends vertically upward from the tip of the horizontal groove 60. Furthermore, a lateral groove 62 is provided at the tip of this vertical groove 61, extending in the circumferential direction in parallel with the horizontal groove 60. A locking convex portion 63 projecting downward is provided on the upper peripheral edge of the horizontal groove 60, and the width dimension _L2 of this portion is set to be larger than the outer diameter D of the protrusion 22a.

Therefore, in such an embodiment, the protrusion 22a of the saucer 22 passes over the locking protrusion 63, and
It is guided upward and has the same effect as the above-mentioned embodiment.

In each of the embodiments described above, the upper part of the elongated hole 24 has a two-stage structure consisting of the engaging part 25 (engaging groove) and the horizontal groove 26, but as shown in FIG. It is also possible to have a one-stage configuration, and the saucer 22 is connected to the elongated hole 24.
Any other configuration may be used as long as it is configured to stop at the top of the holder.

"Effects of the Invention" As explained above, according to the present invention, the following excellent effects can be achieved.

(1) In a dispensing container that has a structure in which a holder that holds the base end of a bar-shaped cosmetic product is screwed into a saucer, a locking mechanism is provided between the saucer and the holder to prevent the holder from loosening due to vibrations during transportation. This prevents the stick from becoming loose and prevents the bar-shaped cosmetic from being damaged. Moreover, since the holder does not loosen even when using the bar-shaped cosmetic, the usability can be improved. Furthermore, since the locking protrusion is set to be located above the male thread of the holder, in addition to the feeling of resistance due to the engagement between the locking protrusion and the locking groove, you can also check the progress of the holder while locking. It has the advantage that the engagement of the mating protrusions can be confirmed, and the operation when exchanging the holder is easy.

(2) When replacing bar-shaped cosmetics, the holder can be made to protrude further upwards from its normal use position and the holding area of the holder can be enlarged, making it easier to screw the holder into place and making it easier to use in normal use. To reliably and easily replace a bar-shaped cosmetic without spoiling the beauty of a dispensing container.
