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. 11 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, when using such a conventional dispensing container, there are problems due to the force of pressing the bar-shaped cosmetic 6 against the application surface or vibrations when carrying it. There is a risk that the screws may come loose, and in this case, there is a risk that the cosmetic bar 6 may be difficult to use, or that the cosmetic bar 6 may 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 is to provide a dispensing container that can securely attach the holder to the saucer without impairing operability when exchanging bar-shaped cosmetics, has a loosening effect, and can prevent the bar-shaped cosmetics from being damaged. This is what I am trying to do.

"Means for Solving the Problems" The present invention connects the base end of a bar-shaped cosmetic to a saucer provided in a cylinder via a holder, and moves the saucer back and forth within the cylinder, thereby allowing the bar-shaped cosmetic to be delivered. In the feeding container for loading and unloading, a female thread is formed on the inner peripheral surface of the saucer, a male thread is provided on the outer peripheral surface of the holder to be screwed into the female thread, and at least one of the saucer and the holder is provided with a lower end thereof. A bullet plate part is provided with elasticity by a slit extending from the plate, and a locking part is formed on the inner circumferential surface of the saucer,
A retaining portion is provided on the outer circumferential surface of the holder to engage with the retaining portion at the end point of the holder's screw movement and restrict the upward movement of the holder, and the retaining portion or retainer is attached to the bullet plate portion. It was formed so that the

"Operation" To attach the bar-shaped cosmetic to the tray inside the cylinder, move the tray to the highest position of the cylinder, insert the holder that holds the base end of the bar-shaped cosmetic into the tray, and tighten the holder. All you have to do is rotate it. By this operation, the holder advances into the saucer, and during its spiral movement, the retaining portion of the holder comes into elastic contact with the locking portion of the saucer, and the resistance force against the rotational operation begins to increase. When the holder is further rotated against this resistance, the bullet plate part is elastically deformed in accordance with the rotation operation, and the retaining part overcomes the locking part and engages with the holder at the end of the spiral movement.

In this way, when the bar-shaped cosmetic is attached to the tray, the retaining part and the locking part are in elastic contact with each other, so even if a force is applied to rotate the holder in the direction of loosening it. , rotation is prevented, and phenomena such as spontaneous loosening do not occur.

It is configured to be rotatably supported by the spiral tube 23 by engaging with an engagement step 23b formed on the inner circumferential surface of the tube 23. Note that escape holes 25a extending in the circumferential direction are formed at the upper and lower ends of the elongated hole 25, respectively.

To further explain the saucer 21, it is formed into a bottomed cylindrical shape having an outer diameter slightly smaller than the inner diameter of the guide cylinder 24 as a whole, and has elongated holes 25 at opposing positions on the upper part of the outer periphery. A protrusion 21a is provided to protrude and engage with the spiral groove 23a via the protrusion 21a. In addition, a female thread 21 is provided on the inner peripheral surface of the saucer 21.
b is formed, and a through hole 26 having a diameter slightly smaller than the inner diameter of the female thread 21b is provided in the bottom plate portion of the saucer 21, and the peripheral edge of the through hole 26 serves as a locking portion 27 that engages with the holder 22. There is.

Further, the holder 22 is formed into a cylindrical shape that is longer than the length of the saucer 21, and its length is such that at least the upper half of the saucer 21 protrudes outward at the highest position of the saucer 21. Set.
Further, a flange portion 22a that contacts the upper end of the saucer 21 is formed on the outer periphery of this holder 22, and the female thread 2 is provided below the flange portion 22a.
A male thread 22b is formed to be screwed into the holder 1b, and a resilient plate portion 29 is provided below the male thread 22b, which is made elastic by a slit 28 extending from the lower end of the holder 22. A retaining portion 30 that engages with the locking portion 27 is provided on the outer peripheral surface of the bullet plate portion 29, and the retaining portion 30
At the end point of the spiral movement of the holder 22, the saucer 2
It is set to engage with the locking portion 27 of No. 1.

Further, when the holder 22 and the bar-shaped cosmetic 6 held in the holder 22 are separated from the saucer 21, they are accommodated in a capsule 35, as shown in FIG. 5, for example. The capsule 35 is mainly composed of a support plate 36 that vertically supports the bar-shaped cosmetic 6 and a cap 37 that is fitted into the support plate 36. 22b
A female thread 36a is provided to be screwed together. In this embodiment, the capsule 35 is configured to store one bar-shaped cosmetic 6, but the capsule 35 is not limited to this, and may also be configured to store a plurality of bar-shaped cosmetics 6. Also good.

In addition, the male screw 22b of the holder 22, the saucer 2
1 female screw 21b and support plate 3 of capsule 35
If the female threads 36a of No. 6 are each multi-thread threads,
This is preferable because the number of rotations when screwing the holder 22 together can be reduced.

In addition, what is indicated by the reference numeral 40 in FIG. 4 is a cap.

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

The spiral cylinder 23 and guide cylinder 24 shown in FIG. 1 are assembled as shown in FIG. 6 is attached and the spiral tube 23 is rotated clockwise, the spiral groove 23a is rotated clockwise and pushes the protrusion 21a of the saucer 21, the saucer 21 is moved upward, and the bar-shaped cosmetic 6 is fed out. If there is no cap 40, the feeding action will be performed until the protrusion 21a of the saucer 21 abuts against the tip of the elongated hole 25, as shown in FIG.

In addition, when the bar-shaped cosmetic 6 is in use, the retaining part 30 of the holder 22 is engaged with the locking part 27 of the saucer 21, so the force pressing the application surface is applied to the bar-shaped cosmetic 6. via holder 22
There is no risk that this screw connection will loosen even if the device is exposed to mechanical forces, so it can be used in a stable state.

Next, when the spiral tube 23 is rotated in the opposite direction while the protrusion 21a is engaged with the relief hole 25a,
Since the spiral groove 23a pushes the protrusion 21a of the saucer 21 downward, the protrusion 21a of the saucer 21 is removed from the relief hole 25a and guided downward, and the bar-shaped cosmetic 6 integrally attached to the saucer 21 via the holder 22 is removed. It is returned toward the lower end and stored in the guide tube 24.

Also, to explain the case of exchanging the bar-shaped cosmetic 6, the protrusion 21a of the saucer 21 is inserted into the escape hole 25a at the upper part of the elongated hole 25, and the saucer 21 is positioned at its highest position.

Next, hold the protruding part of the holder 22 between your fingers and turn it strongly against the resistance force when the retaining part 30 rides on the locking part 27, and if you continue to rotate it, the holder 22 will be separated from the saucer 21. Therefore, in this state, as shown in FIG. 3, if another bar-shaped cosmetic 6 is taken out from the capsule 35 and attached to the saucer 21 along with the holder 22 according to the following procedure, this bar-shaped cosmetic 6 will disappear. Become free. In order to attach the holder 22 to the tray 21, the holder 22 is inserted into the tray 21 and rotated in a direction to tighten it. By this operation, the holder 22 enters into the saucer 21, and in the middle of its screwing, the retaining part 30 of the holder 22
comes into elastic contact with the locking part 27 of the saucer 21, and the holder 2
In accordance with the rotation operation in step 2, the bullet plate portion 29 is elastically deformed, and the bullet plate portion 29 is overcome and engaged at the end point of the spiral movement. Note that the cut-off bar-shaped cosmetic 6 is stored in a capsule 35 as shown in FIG.

In addition, the rod-shaped cosmetic 6 is manufactured by separating the holder 22 from the saucer 21.
For example, as shown in another embodiment of FIG. 6, through holes 45a and 45b are formed in the bottoms of the guide tube 24 and the outer tube 47, respectively. Then, a so-called back-filling method may be used in which a nozzle is inserted through these through-holes 45a and 45b to fill the filling capsule 46 attached to the holder 22 with the cosmetic stock solution. In this case, a seal or the like is pasted on the bottom of the outer cylinder 47 fitted on the outer periphery of the guide cylinder 24 to close the through holes 45a and 45b.
Also, a decorated cap is attached via the connecting tube 48.

Further, FIG. 7 shows another embodiment of the present invention, in which a cylindrical portion 50 is protruded from the inner surface of the bottom plate of the guide tube 24 to make elastic contact with the inner circumferential surface of the holder 22, and the lower limit of the holder 22 is lowered. At this position, the holder 22 is pressed outward by the cylindrical portion 50.

With this configuration, the holder 22 is held firmly pressed against the tray 21 when the bar-shaped cosmetic 6 is stored, so that loosening of the holder 22 can be more reliably prevented.

Further, another embodiment of the present invention will be explained with reference to FIG. 8. 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 55 having a bottomed cylindrical shape having a spiral groove 55a, and a long hole 25 in the lower half, which is longer than the spiral tube 55.
A long cylindrical body 54 is formed with a guide cylinder 56 having a handle, and a protrusion 57a that is operated by the cylindrical body 54 is formed inside the cylindrical body 54, and a locking portion 27 is formed on the inner peripheral surface. The bar-shaped cosmetic 6 is attached to the tray 57 via the holder 22. Note that even with such a configuration, the same effects as those of the above-mentioned embodiment can be achieved.

FIG. 9 shows an example in which an engaging part 60 is provided in the middle of the elongated hole 25 that guides the protrusion 21a of the saucer 21 to engage with the protrusion 21a and restrict its upward movement. The position of the cosmetic 6 is changed when it is used and when it is replaced. That is, the engaging portion 60 is formed on the left side (left side in FIG. 9) of the elongated hole 25 near the upper end.
In the illustrated example, the engagement portion 60 is an engagement groove formed to communicate with the elongated hole 25, and its upper peripheral edge 60a slopes upward at an angle θ toward the upper side of the elongated hole 25. The lower peripheral edge 60b is horizontal and intersects the elongated hole 25 at right angles.

Note that here, the upper peripheral edge 60a of the engaging portion 60
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 21a of the saucer 21 is reciprocated between the lower end of the elongated hole 25 and the engaging part 60). Protrusion 21a of tray 21
is set at an angle such that it will not rise unless a certain amount of force is applied, and the engagement groove 60 and relief groove 2
The distance L between the holders 5a and 5a is set to approximately half the length of the holder 22, and when the saucer 21 rises through this distance L, the upper half of the holder 22 protrudes.

In addition, when the engaging part 60 is provided in the elongated hole 25 in this way, the holder 22 does not protrude during normal use, so that the aesthetic appearance of the dispensing container during use can be improved. Note that the structure of the engaging portion that engages the protrusion of the saucer is not limited to this illustrated example, and the structure is arbitrary.

Further, in the above-mentioned embodiment, the slit 28 is formed in the holder 22 and the bullet plate part 29 is provided, but as shown in FIG. 21 may be provided with a bullet plate portion 29.

"Effects of the Invention" As explained above, according to the present invention, in a dispensing container in which a holder for holding 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. With this provision, the holder does not come loose due to vibrations during transportation, and the bar-shaped cosmetic can be prevented from being damaged. Moreover, since the holder does not loosen even when using the bar-shaped cosmetic, the usability can be improved.
Furthermore, since at least one of the retaining part and the locking part constituting the locking part of the holder is provided on the elastically deformable elastic plate part, the engagement of the retaining part and the locking part can be made elastic. Another advantage is that it can be carried out while the holder is being held, and the rotational operation of the holder is not impaired.
