Description

[Detailed explanation of the invention] This invention uses rod-shaped cosmetics such as eyeliner, eyebrow, eye shadow, lipstick, etc. of different colors and types to appear and retract from both ends of the barrel, and to be used interchangeably. The present invention relates to a cosmetic container with a thin shaft that can be fed out at both ends.

Conventionally, a device in which two sliding shafts for dispensing cosmetics from both ends of the barrel are installed in series is known as a device that dispenses cosmetics from both ends of the barrel. The disadvantage was that the entire container was long despite the small amount of material. As an alternative to this,
102569 and Utility Model Application Publication No. 57-81714 have been proposed. These containers have a short overall length, but the former uses a screw rod with a semicircular cross section and a female threaded hole in the cap to dispense the cosmetics from both ends. )
Since the threaded rod and the female thread are threaded together in a semicircular area, the threaded rod may escape into the part where they are not threaded in the radial direction, resulting in insufficient threading and the core may not be able to be fed out. In the latter case, one spiral tube is used to dispense the left and right cosmetics, so when dispensing one, it is necessary to keep the dispensing protrusion of the other in a loosely fitted position. The feeding operation is complicated, and furthermore, it is difficult to assemble the parts. Moreover, both had the disadvantage that they could not be used by changing the cosmetics as needed.

This invention was made in view of the above-mentioned drawbacks of the conventional technology.
The sliding bodies are movably fitted into the sliding bodies, and both sliding bodies are movably engaged with screw-based feeding mechanisms in the separately formed shaft cylinders, and at least one of the sliding bodies is inserted into the shaft cylinder. By connecting the core chuck with the cosmetics in the core cylinder, which is removably connected to one end, the dispensing operation is smooth, the entire container is compact, and it is particularly suitable for fine writing such as eyeliner. The object of the present invention is to provide a cosmetic container that is formed into a thin shaft and is easy to use, allowing various cosmetics to be easily exchanged depending on the purpose of use.

A first joint 66 is provided with a connecting hole 69 and a mounting hole 70 on either side of a partition wall 68 having a through hole 67, similar to the first joint of the first embodiment, a leaf spring 71 is press-fitted tightly into the connecting hole 69, and a grooved cylinder 72 having a slide groove 73 is attached to the mounting hole 70. The small diameter portion 74 on the outer periphery is inserted into the mounting hole 63 of the shaft tube 61, and the protrusion 75 is fitted into the ring-shaped recessed groove 61a drilled in the mounting hole 63, so that the two are rotatably connected.
The first sliding body 76 has a pipe-shaped push rod 77 with its tip inserted into the through hole 67 of the partition wall 68, and a slider 78 with a protrusion 79 at its rear end which engages with the screw 62 and the slide groove 73. The cartridge 80 has a bottomed cylindrical middle tube 81 which fits into the connecting hole 69 of the shaft tube 61, and a truncated cone-shaped front tube 82 fitted into it by a recess and small protrusions, and a first core tube 84 with a spring 83 loosely fitted on its outer periphery is sandwiched and fixed between the two tubes 81, 82. The first core tube 84 has four guide grooves 86 drilled into the storage hole 85 so as to form a cross-shaped cross section,
One of them is cut and slit 86a except for the tip, and a core chuck 87 with cosmetic A attached thereto is fitted into said storage hole 85, and four claw pieces 88 of the core chuck 87 are fitted into the guide grooves 86, respectively, and protruding pieces 89 protruding from the claw pieces 88 engage with springs 83 provided on the outer periphery that protrude from the slit 86a, thereby constantly urging the core chuck 87 in a direction in which it abuts against the bottom wall of the inner tube 81.
As in the embodiment, a rectangular through hole 92 with an arc is drilled in the bottom wall 91, and a slit 93 is provided to bisect the longitudinal direction of the through hole 92 so as to reach the side. Furthermore, a protrusion 94 is provided on the outer peripheral surface.
This is fitted into a ring-shaped groove 61a drilled in the mounting hole 65 of the shaft tube 61 to rotatably connect the second joint 90. The second core tube 95 has a small projection and a knurl on its small diameter portion, which are fitted and locked into the recess and knurl in the second joint 90, respectively, to be integrally joined, and four guide grooves 97 are drilled in the inner surface of the housing hole 96 so as to form a cross-shaped cross section.
The sliding body 98 has a rod 101 formed in a rectangular cross section with a flat portion 100 except for a stopper at the rear end where a screw 99 is left, as in the first embodiment, and a core chuck 102 at its tip. The rod 101 is inserted into a rectangular through hole 92 cut in a slit 93 in the bottom wall 91 of the second joint 90, and its tip is inserted into the partition wall 64 of the shaft cylinder 61.
The lead chuck 102 is threadedly engaged with the screw hole 64a engraved in the lead chuck 64, and is further disposed in the pipe of the push rod 77 of the first sliding body 76. The lead chuck 102 has four claw pieces 103, and holds the cosmetic B. The lead chuck 102 is slidably fitted in the guide groove 97 of the second lead cylinder.

With this structure, when the cartridge 80 is fitted and fixed to the first joint 66 and the first joint 66 is rotated with respect to the shaft cylinder 61, the push rod 77 of the first sliding body 76 is inserted into the screw 62 of the slider 78. The tip is pushed out by a protrusion 79 that engages with the slide groove 73, and its tip presses the rear end of the core chuck 87 in the cartridge 80, moves it forward against the tension of the spring 83, and moves from the tip of the front tube 82. Cosmetic A can be used by making it stick out. When retracting the cosmetic A, the first joint 4 is rotated in the opposite direction to the above and the push rod 77 is retracted.
It can be stored immersed inside. Furthermore, when the cartridge 80 is removed from the equiaxial cylinder 61 to be replaced, the core chuck 87 automatically moves to come into contact with the bottom wall of the middle cylinder 81 due to the tension of the spring 83, and the cosmetic A gradually protrudes from the front cylinder 82. Never.
On the other hand, when using cosmetic B, by rotating the second core cylinder 95 with respect to the shaft cylinder 61, the flat part 100 of the second sliding body 98 and the through hole 92 of the second joint fit together, and the screw 99 By screwing into the screw hole 64a, the second sliding body 98 moves forward and backward in accordance with the forward and reverse rotation of the second core cylinder 95.
The cosmetic B attached to the core chuck 102 can be made to appear and disappear from the tip of the second core tube 95.

As detailed above, in each of the embodiments, the second sliding body is further fitted into the pipe-shaped first sliding body disposed in the threaded cylinder, so that the length of the entire container can be reduced. It can be formed short and the first
Since the sliding body and the second sliding body are separately screwed into independent screw bodies, they can be freely selected and used. At this time, since both sliding bodies are not configured with cuts or the like that change the diameter dimension as in the past, both sliding bodies are securely screwed into their respective threaded bodies, and chattering occurs due to changes in diameter dimension during rotation operation. Cosmetics can be applied smoothly without causing any problems. Furthermore, a screw is carved only on the inner surface of the threaded cylinder, and the first sliding body is fed out with this, and a screw is carved in the second sliding body itself, and the second sliding body is placed inside the first sliding body. Therefore, it has the advantage that the shaft diameter of the entire container can be formed into a narrow shaft. In addition, with this invention, both the first and second sliding shafts can be formed to have a small diameter, so they are connected to the core chuck in which the cosmetic material is attached in the core cylinder, and are configured in a cartridge type, so that only one shaft can be used. If a wide variety of cosmetic cartridges are prepared in advance, the user can freely select and replace the cosmetic cartridges and use them, making it easy to apply makeup and having various effects with excellent usability.
