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'' Traditionally, as containers for bar-shaped cosmetics, such as lipsticks and blushers, so-called dispensing containers have been used, which have a structure in which a saucer to which the base end of the bar-shaped cosmetic is attached is moved back and forth (up and down) within a cylinder. Since these bar-shaped cosmetics can be rolled out and used when applied and used, even relatively expensive cosmetics have the advantage of being able to be used to the end. On the other hand, since most of the cosmetic is exposed, great care must be taken to prevent damage when storing the cosmetic in the cylinder. For this reason, when assembling the dispensing container, the bar-shaped cosmetic is often housed in the cylinder by hand, resulting in poor work efficiency.

On the other hand, many of these types of dispensing containers do not have a means for exchanging the cosmetics (lipsticks) stored therein, and these containers must be disposed of as waste after use. Furthermore, manufacturers have had the problem of having to dispose of defective products in their entire container if lipsticks are damaged or otherwise defective during the cosmetic storage process.

Additionally, containers that do not have a means to exchange the cosmetics themselves are meant to be used only for one cosmetic product (lipstick), so if you want to increase the variety of lipsticks, you will need to use containers for different types of lipsticks. In addition to the dissatisfaction, it was difficult to make the containers more high-quality because it was necessary to ensure that the cost of the containers themselves did not become a burden to the users.

``Problems to be solved by the invention'' The present invention was proposed based on this background, and it improves the applicability to mechanization of the work of applying stick-shaped cosmetics, and also makes it easier to replace the applied stick-shaped cosmetics. It is easy to use and allows you to use different types of cosmetics in the same container.
It is possible to improve the quality of containers, and also aims to reduce the rate of defective products.

"Means for Solving the Problems" The present invention provides a removable holder for holding the base end of a bar-shaped cosmetic on a tray that moves up and down in the inner cylinder by the relative rotation of the spiral cylinder and the inner cylinder. A locking groove is provided in the vicinity of the upper end of the elongated hole formed in the peripheral wall of the inner cylinder to guide the protrusion of the saucer in the vertical direction, and is connected to the elongated hole and restricts upward movement of the protrusion. A horizontal groove is provided above the locking groove and communicates with the elongated hole, into which the projection of the saucer is inserted.

"Operation" The present invention having such a configuration moves the tray higher than in the normal use state, thereby
The holder that holds the base end of the bar-shaped cosmetic sticks out from the tip of the inner cylinder, making it possible to replace the holder, and restricting the downward movement of the saucer when replacing the holder, so that the helical cylinder and the inner cylinder can be separated. It is designed to restrict the relative rotation of the

"Example" The first embodiment of the present invention will be described below in Figures 1 to 4.
To explain with reference to the drawings, in the drawing, reference numeral 1 denotes a helical cylinder, numeral 2 an inner cylinder which is rotatably inserted into the helical cylinder 1, and numeral 3 which is inserted into the inner cylinder 2 and said helical cylinder 1. A saucer operated by relative rotation between the inner cylinder 2 and the inner cylinder 2. Reference numeral 4 is a holder that is detachably attached to the tray 3 and holds the base end of the bar-shaped cosmetic A. It constitutes the main component of the dispensing container.

A spiral groove 5 is formed on the inner peripheral surface of the spiral tube 1, and a decorative tube 6 is fixedly fitted on the outer periphery. A long hole 7 extending in the axial direction is drilled, and a circumferential protrusion 8 is formed at the upper end, and the helical cylinder 1 is fitted between the circumferential protrusion 8 and the gripping part 9 of the inner cylinder 2. The basic structure is rotatably supported by a spiral tube 1.

The tray 3 has a cylindrical shape with a bottom as a whole, and projections 10 that engage with the spiral groove 5 through the elongated hole 7 are located at opposing positions on the upper part of the outer periphery.
is provided in a protruding manner and is configured to move in the vertical direction (in the vertical direction in FIG. 1) by relative rotation between the spiral cylinder 1 and the inner cylinder 2, and the inner circumferential surface thereof has a protrusion 11 that goes around in the circumferential direction. is provided.

On the other hand, the holder 4 has a substantially cylindrical shape as a whole, and has a flange portion 12 on its upper outer periphery that abuts the upper end of the tray 3, and a flange portion 12 that comes into contact with the protrusion 11 of the tray 3 on its lower outer periphery. A stop ridge 13 is provided, and a groove 14 extending from the lower end facilitates inward elastic deformation.

Next, to supplement the explanation of the elongated hole 7 of the inner cylinder 2 with reference to FIG. 2, this is because the saucer 3 is raised toward the tip end on the left side periphery near the upper end (left side in FIG. 2). At this time, a locking groove 15 that engages with the protrusion 10 of the saucer 3 to restrict its upward movement.
is formed to communicate with the elongated hole 7, and the upper peripheral edge 15a of the locking groove 15 is inclined upward at an angle θ toward the upper side of the elongated hole 7, and the lower peripheral edge 15b is horizontal and intersects the elongated hole 7 at right angles. In addition, this locking groove 1
A lateral groove 16 is formed above the groove 5 so as to communicate with the upper end of the elongated hole 7 and into which the protrusion 10 of the tray 3 is inserted.

Incidentally, the inclination angle θ of the upper peripheral edge 15a of the locking groove 15 is such that when the bar-shaped cosmetic A is normally used (i.e., when the protrusion 10 of the saucer 3 is connected to the lower side of the elongated hole 7 and the locking groove 1
5), the inclination angle θ is set at such an angle that the protrusion 10 of the saucer 3 will not rise unless a certain amount of force is applied. That is, when the bar-shaped cosmetic A is normally used, the protrusion 10 of the tray 3 is locked to the upper peripheral edge 15a of the locking groove 15 and its upward movement is restricted, but the inclination angle of the upper peripheral edge 15a If θ is large, the helical cylinder 1 and the inner cylinder 2 will rise with slightly larger torque than the torque used to rotate them during normal use, and the function of the locking groove 15 will not be fully exerted, so the protrusion of the saucer 3 will easily The angle θ is set at a torque value that does not cause the locking groove 10 to rise from the locking groove 15.

By the way, in the figure, the reference numeral 17 is a capsule for storing the bar-shaped cosmetic A therein, and the holder 4 is removably fitted into the inner periphery of the proximal end of the capsule. Also,
A fitting cylinder part 18 having an inner diameter larger than the outer diameter of the cosmetic tube 6 is integrally provided on the outer periphery of the proximal end of the capsule 17. As shown, the container body 19, which is a cylinder with a bottom, is removably fitted together to form a cartridge case K that holds the bar-shaped cosmetic A in a stored state.

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

The operation of normally using this dispensing container is similar to that of a general dispensing container. That is, when the helical tube 1 is rotated clockwise in the assembled state as shown in FIG. 3A, the helical groove 5 rotates clockwise and pushes the protrusion 10 of the tray 3, causing the tray 3 to move toward the tip. By this operation, the holder 4 attached to the tray 3 and the cosmetic bar A are moved together with the tray 3 toward the tip, and the cosmetic bar A protrudes from the tip of the inner cylinder 2. Then, the protrusion 10 of the saucer 3 is inserted into the locking groove 15, and the resistance force against the rotational operation of the spiral cylinder 1 increases, so that the saucer 3 is used in a state in which upward movement is restricted.

On the other hand, when the spiral tube 1 is rotated counterclockwise, the spiral groove 5 pushes the protrusion 10 of the saucer 3 toward the proximal end, so that the bar-shaped cosmetic A integrally attached to the saucer 3 via the holder 4 is It is returned to the end direction and housed in the inner cylinder 2.

Next, to explain the case of exchanging the bar-shaped cosmetic A, the protrusion 10 of the saucer 3 is inserted into the locking groove 15, and the spiral tube 1 is further rotated clockwise against the resistance force against the rotation operation of the spiral tube 1. Then, the protrusion 10 rises along the upper peripheral edge 15a of the locking groove 15 as shown by the arrow in FIG. 2, and is inserted into the horizontal groove 16 at the upper end of the elongated hole 7. In this state, the holder 4 and the bar-shaped cosmetic A are extended from the normal use position (that is, the position where the protrusion 10 of the saucer 3 is locked in the locking groove 15) as shown in FIGS. 2 and 3B. Since the holding part for taking out the holder 4 becomes larger, the holding part for taking out the holder 4 can be easily taken out.

Then, pinch the protruding part of the holder 4 with your fingers and pull it out, or insert a capsule 17 or the like into the holder 4, separate the holder 4, and insert another bar-shaped cosmetic A together with the holder 4 into the saucer 3. The locking protrusion 14 of the holder 4 is attached to the protrusion 13 of the saucer 3.
By engaging the two, the bar-shaped cosmetic A can be moved in and out.

In addition, in the exchange operation of the rod-shaped cosmetic A,
The cut-out bar-shaped cosmetic A is stored in a cartridge case K consisting of a capsule 17 and a container body 19, as shown in FIG. In addition, when the bar-shaped cosmetic A is attached to the receiving tray 3, as shown in FIG. After the engagement, the bar-shaped cosmetic A can be reliably prevented from being damaged by lowering the tray 3 and removing it.

By the way, when inserting the holder 4 into the tray 3 when installing the bar-shaped cosmetic A, the insertion of the holder 4 naturally applies a force pushing the tray 3 downward (downward in FIG. 3). However, since the protrusion 10 of the saucer 3 is inserted into the horizontal groove 16, the saucer 3 does not go down and the spiral tube 1
There is no relative rotation between the inner cylinder 2 and the inner cylinder 2. Therefore, when inserting the cosmetic bar A, there is no need to hold down the spiral tube 1 and the inner tube 2 so that they do not rotate relative to each other, so it is particularly useful for manufacturers to mechanize the installation work of the cosmetic bar A. However, its applicability can be improved. That is, the attachment of the bar-shaped cosmetic A is carried out by pushing the cosmetic A stored in the capsule 17 into the receiving tray 3, and since the receiving tray 3 does not descend when pushing the cosmetic A, the cosmetic A is reliably attached. can be installed.

Further, in the case of the dispensing container of this embodiment, when the tray 3 is at its highest position, the upper end of the tray 3 is connected to the inner tube 2.
It does not protrude from the tip of the holder 4.
Since the protrusion 11 that engages with the locking protrusion 13 is formed in the center of the tray 3, there is an advantage that the tray 3 and the holder 4 can be easily centered and pushed into each other.

Note that the cartridge case K for storing the bar-shaped cosmetic A may be, for example, as shown in FIG.
If the shape of the capsule 17 is changed to form the whole into a straight cylindrical shape, and the fitting cylindrical part 18 is integrally extended from the lower outer periphery of the capsule 17',
Since a small gap is created between the rod-shaped cosmetic A and the cosmetic A by the thickness of the holder 4 in the stored state, the cosmetic A can be removed more easily.

FIG. 6 shows still another example of the cartridge case, which includes a cylindrical capsule 20 that surrounds the holder 4 and the cosmetic A, and an upper lid 21 and a lower lid 22 that cover the upper and lower openings of the capsule 20. A cartridge case K is constructed from the capsule 2.
A fitting cylinder 24 for holding the holder 4 is provided on the inner surface of an annular flange portion 23 protruding from the inner circumferential surface of the holder 4.

Next, a second embodiment of the present invention will be explained with reference to FIGS. 7 and 8. In this embodiment, the tray 3 and the holder 4 are respectively modified, and the tray 3' is attached to the upper part by a groove 30 starting from the upper end. Four elastic pieces 31 are formed, and a protrusion 32 is provided protruding from the inner surface of each elastic piece 31. On the other hand, the holder 4' that fits into the tray 3' has a protrusion 3 on the outer periphery of the tray 3'.
A circumferential groove 33 that fits into the circumferential groove 2 is formed, the upper part of the circumferential groove 33 has a larger diameter than the lower part, and a knurled groove 34 extending in the length direction is provided on the outer periphery of the circumferential groove 33.

In addition, in this second embodiment, the saucer 3'
With the protrusion 10 inserted into the horizontal groove 16 at the upper end of the elongated hole 7, the elastic piece 31 of the tray 3' protrudes from the upper end of the inner cylinder 2, as shown in FIG. Almost the same effects can be achieved, and the knurled grooves 34 allow air to enter the capsule 17 when the capsule 17 is removed, making it easier to separate from the bar-shaped cosmetic A.

Further, FIGS. 9 and 10 show a third embodiment of the present invention, and show still another modification of the tray 3 and the holder 4. The saucer 3'' shown here is formed into a bottomless cylindrical shape, and has an annular protrusion 11 formed at the lower part of the inner periphery, and the holder 4'' is formed into a straight cylindrical shape as a whole, and has the protrusion 11 formed at the lower part. A fitting groove 35 is provided which fits into the fitting groove 35 .

Note that even with the dispensing container of this embodiment, substantially the same effects as those of the previous embodiment can be achieved.

Further, a fourth embodiment of the present invention will be described with reference to FIGS. 11 and 12. The dispensing container shown here includes a helical tube 40 that is a bottomed cylinder having a helical groove 5 on its inner peripheral surface, and an inner tube 41 that is rotatably inserted into the inner circumference of the helical tube 40 and is longer than the helical tube 40.
a tray 42 inserted into the inner tube 41 and moved up and down by relative rotation between the spiral tube 40 and the inner tube 41; and a tray 42 that is detachably attached to the tray 42 and holds the base end of the bar-shaped cosmetic A. holder 43
A long hole 7, a locking groove 15, and a horizontal groove 16 are provided at opposing positions on the lower half circumferential wall of the inner cylinder 41.
Further, a protrusion 1 that engages with the helical groove 5 through the long hole 7 is formed on the outer periphery of the proximal end of the receiving tray 42.
0 is set. Further, an elastic engagement piece 31 is formed at the upper end of the tray 42 by a split groove 30, and a protrusion 32 that engages with the circumferential groove 33 of the holder 43 is protrudingly provided on the inner surface of the elastic engagement piece 31. .

Therefore, even with the dispensing container of this embodiment, the same effects as those of the previous embodiment can be achieved.

In this way, in the present invention, regardless of the shape of the dispensing container, as long as it basically includes the spiral tube 1, the inner tube 2, the receiving tray 3, and the holder 4, it is possible to By forming the stop groove 15 and the lateral groove 16, the unique effects of the present invention can be exhibited.

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

(a) A locking groove that communicates with the long hole and restricts upward movement of the protrusion is provided near the upper end of the long hole formed in the inner cylinder, and a locking groove that is long above the locking groove is provided. Since a horizontal groove is provided in which the protrusion of the saucer is inserted in a form that communicates with the hole, during normal use, the bar-shaped cosmetic can be used by locking the protrusion of the saucer in the locking groove. When replacing the holder, the holder can be lifted further upward from the normal use position by pushing the protrusion up along the upper periphery of the locking groove and locking it in the lateral groove, making it easy to replace the holder. can. Further, during this replacement, since the horizontal groove prevents the protrusion from descending, when the holder is inserted into the receiving tray, the receiving tray does not descend within the inner cylinder, and the holder can be easily installed. Therefore,
It is possible to easily mechanize the operation of applying bar-shaped cosmetics, and work efficiency can be greatly improved.

Moreover, since the protrusion that is locked in the horizontal groove is directly inserted into the elongated hole by the operation of inserting the tray, it is possible to easily shift the bar-shaped cosmetic from the replacement state to the use state.

As a result of the above, bar-shaped cosmetics can be easily replaced, so for users, for example, relatively expensive containers can be used repeatedly without disposing of them as waste, and for manufacturers, it is possible to replace the entire container. There is no need to dispose of the product as a defective product, and the rate of defective products can be reduced, and the container can be made of higher quality.
