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 in a cartridge type manner.

``Prior Art'' Conventionally, as a container for storing bar-shaped solid cosmetics, such as lipstick and blush, a saucer to which the base end of the bar-shaped cosmetic is attached is moved back and forth (up and down) inside a cylinder.
These cosmetics have the advantage of being able to be used until the end, even if they are relatively expensive, since they can be used by rolling out the bar-shaped solid cosmetics when using them. Ta. On the other hand, since most of the cosmetic is exposed, great care must be taken to prevent damage when storing the cosmetic-filled tray in a container. For this reason, when assembling the container, the container with the cosmetic is often housed manually, resulting in poor work efficiency.

On the other hand, in order to prevent cosmetics from being damaged and to improve workability, a method is used in which a mold cylinder is fitted in advance to a tray in the inner cylinder, the cosmetics are filled through a window hole in the bottom plate of the tray, and the cosmetics are solidified and supported in the tray. However, most containers do not have a means to replace the bar-shaped cosmetic itself, so if the filled cosmetic is defective, the entire container has to be rejected. There is.

``Purpose of the invention'' The present invention was proposed based on this background, and aims to prevent damage when storing bar-shaped cosmetics, to make it easy to operate and to replace the bar-shaped cosmetics. The purpose is to provide a dispensing container that can be used for

"Structure of the invention" The present invention provides a dispensing container in which the bar-shaped cosmetic is filled and supported in a tray through a window hole at the bottom of the inner cylinder, and the bar-shaped cosmetic is taken in and out by moving the tray up and down within the inner cylinder. A mold for filling cosmetics is removably provided on the tray via a holder that holds the base end of the cosmetic, and the outer diameter of the mold is set to be slightly larger than the inner diameter of the inner cylinder, and the length of the inner cylinder is A guide groove for guiding the protrusion of the saucer further upward than the elongated hole is communicated with the upper part of the hole, and the lower end of the mold cylinder is located above the upper end of the inner cylinder at the highest position of the protrusion.

``Embodiment'' Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 5. In the figures, reference numeral 1 denotes a helical cylinder having a helical groove 2 on the inner peripheral surface, and numeral 3 denotes the helical cylinder. 1, an inner cylinder 4 is inserted into the inner cylinder 1 and is movable vertically (up and down in FIG. 1) by rotating the spiral cylinder 1; 5 is a tray; This is a holder that is detachably attached to the container 4 and holds the base end of the cosmetic bar 6, and these reference numerals 1 to 5 constitute the main members of the dispensing container. Further, a mold cylinder 7 for filling cosmetics is removably fitted into the outer periphery of the tip of the holder 5, and when the mold cylinder 7 is fitted into the tray 4 via the holder 5, it is inserted into the inner cylinder. 3
The basic structure is such that a molten cosmetic is filled into the mold tube 7 through the window hole 3a at the bottom and through the window hole 4a of the saucer 4.

A decorative tube 8 is fixedly fitted onto the outer periphery of the spiral tube 1. Further, the inner cylinder 3 has elongated holes 9 extending in the axial direction formed at opposing positions on its circumferential wall, and a circumferential protrusion 10 is formed at the upper end, and a gripping portion between the circumferential protrusion 10 and the inner cylinder 3 is formed. By fitting the helical tube 1 between the helical tube 11 and the helical tube 11, the helical tube 1 is rotatably supported. On the other hand, a horizontal groove 12 is formed in the upper part of the peripheral wall of the inner cylinder 3 and extends horizontally along the circumferential direction so as to communicate with the elongated hole 9.
A guide groove 1 extending vertically upward from the tip of the
3 is provided, and the protrusion 14 of the receiving tray 4 is guided further upward to position the lower end of the mold cylinder 7 above the upper end of the inner cylinder 3.

To supplement the explanation of the structure of the horizontal groove ₁₂ with reference to FIG. A convex portion 15 protruding downward (downward in FIG. 3) is provided on the upper peripheral edge of the tip. The convex portion 15 locks the protrusion 14 of the saucer 4 and limits its movement, and the portion where the protrusion 14 is locked is the inclined portion 1 that slopes toward the elongated hole 9.
It is considered to be 5a. Note that the width l ₂ between the lower edge of the convex portion 15 and the lower peripheral edge of the horizontal groove 12 is equal to
The length is set to be at least equal to or larger than the outer diameter D of the protrusion 14 . Further, a protrusion 16 is provided on the lower peripheral edge of the base end side of the horizontal groove 12.
An inclined portion 16a is provided on the guide groove 13 side of the protruding portion 16 (left side in FIG. 5) so as to correspond to the inclined portion 15a of the convex portion 15.

Now, to explain the saucer 4 and the holder 5 with reference to FIGS. 2 and 3, the saucer 4 is formed into a bottomed cylindrical shape having an outer diameter slightly smaller than the inner diameter of the inner cylinder 3, and the bottom A filling window hole 4a is provided. In addition, the saucer 4
A protrusion 14 that engages with the spiral groove 2 through the elongated hole 9 is formed at opposing positions on the outer periphery of the protrusion 14, and four elastic engagement pieces 18 are provided at the upper end by a split groove 17 extending from the protrusion 14. It will be done. Note that the elastic engagement piece 1
A protrusion 19 is provided on the inside of the holder 8 so as to fit into the circumferential groove 20 of the holder 5 .

On the other hand, a holder 5 stored in the tray 4
is formed into a cylindrical shape longer than the tray 4, and has a flange portion 21 on its upper outer periphery that abuts the upper end of the tray 4, and a knurled groove 22 is formed on the outer periphery above the flange portion 21.

Further, to explain the details of the mold cylinder 7 for filling cosmetics with reference to FIG. 4, the outer diameter d ₁ of the mold cylinder 7 is set to be slightly larger than the inner diameter d ₂ of the inner cylinder 3. Due to the dimensional difference between d ₁ and d ₂ , the mold tube 7
The lower end of the inner cylinder 3 is locked to the upper end of the inner cylinder 3.

Therefore, in order to load cosmetics into a dispensing container with such a structure, first, as shown in FIG. , fit the cosmetic filling mold cylinder 7 into the holder 5, and insert the mold cylinder 7 into the inner cylinder 3 while elastically deforming the inner cylinder 3 outward in the radial direction, as shown in FIG. Push it into. Next, turn the container upside down and remove the inner cylinder 3 and saucer 4.
The cosmetic material in a molten state is injected into the mold tube 7 through each of the window holes 3a and 4a to be pseudo-solidified, and the mold tube 7 is removed. Note that this mold cylinder 7 is removed as follows. That is, from the state shown in FIG. 4A, the spiral tube 1 is rotated clockwise and raised until the protrusion 14 of the saucer 4 is engaged with the protrusion 15 of the horizontal groove 12. Next, when the protrusion 14 is locked to the convex portion 15, push the mold tube 7 downward once to remove the spiral tube 1.
Rotate clockwise. As a result of this operation, the protrusion 14 locked to the protrusion 15 is lowered, guided under the protrusion 15 by the inclined part 16a of the protrusion 16, and inserted into the guide groove 13 as shown in FIG. 4B. It is locked at its upper end. In this state, the mold cylinder 7
The lower end of is located above the upper end of the inner cylinder 3, and the inner cylinder 3 has been restored to its original state.

In this way, when the projection 14 of the tray 4 is inserted to the upper end of the guide groove 13, the spiral cylinder 1 is then rotated in the reverse direction to lower the tray 4 as shown in FIG.
Air is introduced into the mold tube 7 from 2, and the mold tube 7 is detached from the holder 5. During the downward movement of the tray 4, the projection 14 is pushed downward by the spiral groove 2 and advances, so that it is inserted into the long hole 9 without being stopped by the convex portion 15. Therefore, the fingers rotating the spiral tube 1 do not experience any resistance when the projection 14 gets over the convex portion 15,
The spiral cylinder 1 can be rotated smoothly.

Next, a case where the bar-shaped cosmetic 6 is replaced will be explained. In FIG. 4D, pull out the cosmetic 6 together with the holder 5 from the tray 4 by holding the holder 5, attach the new holder 5 fitted with the mold tube 7 to the tray 4, and as shown in FIG. housed inside,
Cosmetic material may be filled into the mold cylinder 7 according to the procedure described above.

In addition, the operation of normally using this dispensing container is the same as that of a general dispensing container, and when the spiral tube 1 is rotated clockwise in the assembled state as shown in Fig. 4 D, the spiral groove 2 rotates clockwise. Then, the protrusion 14 of the saucer 4 is pushed, and the saucer 4 is moved toward the distal end. By this operation, the holder 5 and the cosmetic bar 6 attached to the saucer 4 are moved toward the tip of the cosmetic bar 6 together with the saucer 4.
protrudes from the tip of the inner cylinder 3. Then, the protrusion 14 is engaged with the convex portion 15 of the horizontal groove 12, and the tray 4 is used in a state where its movement is stopped.

On the other hand, when the spiral tube 1 is rotated counterclockwise, the spiral groove 2 pushes the protrusion 14 of the saucer 4 toward the proximal end, so that the bar-shaped cosmetic 6 integrally attached to the saucer 4 via the holder 5 is It is returned to the end direction and housed in the inner cylinder 3.

FIG. 6 shows another embodiment of the present invention, in which a lateral groove 30 extending along the circumferential direction from the tip (upper end) of the guide groove 13 is formed to communicate with the guide groove 13. With such a structure, the protrusion 14 of the receiving tray 4 is inserted into the horizontal groove 30 at the highest position, so the holder 5 is inserted into the horizontal groove 4.
When inserting the holder 5 into the holder, the tray 4 does not descend due to the insertion of the holder 5, and therefore, relative rotation between the helical cylinder 1 and the inner cylinder 3 does not occur, so the holder can be inserted without fixing them. Fitting can be performed.

"Effects of the Invention" As explained above, according to the dispensing container of the present invention, the bar-shaped cosmetic is filled through the window hole at the bottom of the inner cylinder into the mold cylinder that fits into the receiving tray via the holder, and is solidified. Because of this structure, it is possible to prevent damage during the mounting operation.

Removal (removal) of the cosmetic filling mold tube
This can be done simply by rotating the spiral tube 1, so it is possible to improve work efficiency and prevent damage to the cosmetic material when removing the mold tube.

Since the bar-shaped cosmetic can be easily replaced, if filling with the cosmetic fails, only the cosmetic can be replaced, and there is no need to dispose of the entire container as defective.

In the horizontal groove 12 portion communicating with the upper end of the long hole 9,
Convex portion 15 that limits movement of protrusion 14 of saucer 4
Since the lower end of the mold tube 7 is located at the upper end of the inner tube 7 when the protrusion 14 is positioned at the upper end of the guide groove, the cosmetic material 6 may be larger than necessary in a normal cosmetic dispensing operation. This prevents the holder from falling out, which not only prevents erroneous operations such as accidentally pulling out cosmetics or releasing the mating state between the saucer 4 and the holder 5, but also prevents the holder 6 from being inserted into the inner cylinder. Since it is located and is not exposed to the outside, it is possible to improve the appearance in normal use.

The vertical movement of the tray 4 can be controlled with an extremely simple configuration of simply providing the horizontal groove 12 communicating with the elongated hole 9, the guide groove 13, and the convex portion 15 on the peripheral wall of the inner cylinder 3. Not only the manufacturability of the inner cylinder 3 itself, but also the structure of the container as a whole can be simplified and the manufacturability can be improved.
Moreover, assembly is correspondingly easier.

Since the protrusion 14 that engages with the elongated hole 9 and the spiral groove 2 is provided only on the tray 4, it is not only easy to configure and assemble, but also has almost the same operability during normal use as the conventional one. In the same way, it is possible to configure the structure so that rattling does not occur.

It has various excellent effects such as.
