Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a replaceable container for storing bar-shaped cosmetics such as eyeliner, eyebrow, eyeshadow, lipstick, etc.

Conventionally, cosmetic containers have often been single-use, disposable containers, which are wasteful, and have disadvantages such as the need for multiple types of cosmetic containers, which are bulky and inconvenient to carry.

This invention improves on these conventional drawbacks by configuring the dispensing part and the holder part to be detachable, thereby eliminating waste by replacing only the dispensing part, and making it possible to connect different types of cosmetics. By doing so, it is possible to carry a variety of cosmetics at the same time in a compact manner, and to provide a cosmetics container that is excellent in protecting fragile cosmetics.

Embodiments of the configuration of the present invention shown in the drawings will be described in detail below.

Figures 1 and 2 show the basic first diagram of this invention.
FIG. 3 shows the second embodiment, and FIGS. 4 to 7 show the third embodiment.

First, to explain the first embodiment, reference numeral 1 is a core cylinder, which has a knob part 2 and an insertion part 3, and has an inner cylinder 4 extending rearward from the tip end on the inner surface. A through hole 5 is bored in this, and four sliding grooves 6 are formed on the circumferential surface of the through hole 5 so as to eliminate the cruciform cross section, one of which opens on the outer surface of the inner cylinder 4. Cut grooves. Reference numeral 7 denotes a cylindrical threaded cylinder, which is fitted onto the outer peripheral surface of the inner cylinder 4 of the core cylinder 1, and has a female thread 8 carved in its inner surface and a coupling hole 10 with a spline 9 carved in its bottom. Further, a ring protrusion 11 is provided on the outer circumferential surface of the core tube 1, and the ring protrusion 11 is inserted into a ring groove 12 formed on the inner wall surface of the core tube 1, so that the threaded tube 7 is rotatably attached. Reference numeral 13 is a core chuck, with four claws 15 protruding forward from the base 14, to which the cosmetic A is sandwiched,
The claw pieces 15 are fitted into the sliding grooves 6, respectively, and are guided by the slide grooves 6 to move forward and backward. In addition, a protrusion 16 is provided on the base 14, and a sliding groove 6 is cut out from the protrusion 16.
It passes through and is screwed into the female thread 8 of the threaded cylinder 7. 17
is a holder with an insertion part 3 for the core tube 1 on the outer peripheral surface.
The outer cylinder 18 is attached so as to be inserted therein, and a connecting rod 19 is provided protruding from the center of the tip, and a rib 20 is formed on the connecting rod 19 to engage with the spline 9 of the coupling hole 10. , this is the holder part.

With this structure, if you select the core tube 1 containing the cosmetic A you want to use and insert its insertion portion 3 into the outer tube 18 of the holder, the holder 17
The connecting rod 19 is fitted into the coupling hole 10 of the threaded cylinder 7,
Since the core tube 1 is integrally connected to the holder part,
When the outer cylinder 18 is rotated by gripping the knob 2 of the core cylinder 1, the connecting rod 19 of the holder 17 and the coupling hole 10 of the threaded cylinder 7 are fixed in the rotational direction by the rib 20 and the spline 9. Since the rotational force of the holder 17 is transmitted to the threaded cylinder 7 and rotates, the protrusion 16 of the core chuck 13 that is engaged with the threaded cylinder 7 has a female thread 8.
The cosmetic material A, which is guided by the sliding groove 6 and clamped by the claws 15 of the core chuck 13, can be made to protrude from the tip of the core tube 1. If the holder 17 is rotated in the opposite direction, the core chuck 13 will move back and the cosmetic A can be stored in the core tube 1 in the opposite direction. Furthermore, when you finish using cosmetic A or when you want to use another cosmetic A,
It is sufficient to remove the core tube 1 from the holder 17 and replace it with another core tube 1.

Next, in the second embodiment shown in FIG. 3, the holder part is improved, and a receiving ring body 23 is rotatably fitted into an outer cylinder 22 attached to a holder 21. The engaging protrusions 24 bulge inward at a plurality of locations. Further, a sleeve 25 is fixed to the tip of the outer cylinder 22 to prevent the receiving ring body 23 from being pulled out.

With this configuration, when the core cylinder 1 is connected to the holder part, the insertion part 3 is connected to the engagement protrusion 2 of the receiving ring body 23.
4, and since the receiving ring body 23 is rotatably attached, the core cylinder 1 can be smoothly rotated with respect to the holder portion.

Further explaining the third embodiment shown in FIGS. 4 to 7, the core tube 31 has a knob portion 32 and an insertion portion 33.
At the same time, an inner cylinder 34 is fitted to the tip of the inner surface, and four sliding grooves 35 are formed in the inner cylinder 34 as in the first embodiment. Further, a coil spring 36 is inserted into the outer circumferential surface of the inner cylinder 34, and the bent portion 37 at the rear end is fitted and fixed into the cut groove 39 of the drive coupling body 38. A ring groove 40 is bored in the drive coupling body 38, and a protrusion 4 on the inner surface of a ring stopper 43 having a cut 44 is provided.
5, and by rotatably fitting the protrusion 46 on the outer surface and the ring groove 47 on the inner surface of the insertion part 33 of the core tube 31, the drive coupling body 38 is aligned with the axis of the core tube 31. It is fixed in the direction and rotatable in the circumferential direction. Further, at the rear end of the drive coupling body 38, a protruding rod 42 having several ribs 41 formed on its outer peripheral surface is provided at the center thereof. The core chuck 48 has a base portion 49, a claw piece 50, and a protrusion 51 as in the first embodiment, and the claw piece 40 is fitted and guided within the sliding groove 35 and moves forward and backward. An outer cylinder 53 is attached to the holder 52 so that the insertion part 33 of the core cylinder 31 is inserted therein, and a connecting rod 54 is protruded from the center of the tip, and a fitting hole 55 is bored in the connecting rod 54. With,
A spline 56 is formed on its inner surface. Further, a shallow groove 57 is formed on the outer peripheral surface of the continuous rod 54, and a ring 59 having a cut 58 is rotatably fitted into the groove.

With this structure, when the core cylinder 31 is connected to the holder part and the holder part is rotated, the connecting rods 54 and the protruding rods 42 are connected to the splines 56 and the ribs 41.
The coil spring 36 can be reliably rotated by the engagement of the ring 59 and the stop ring 43 are rotatably fitted to the connecting rod 54 and the protruding rod 42, so that the coil spring 36 can be rotated reliably. The driving force can be easily transmitted to the coil spring 36.

As described above with respect to each of the embodiments, the cosmetic container of the present invention is used by freely selecting different types of cosmetics and attaching them to the holder.
Since the core tube containing each cosmetic is formed with a short axis, it is more compact than a conventional single cosmetic container and is convenient to carry. Furthermore, since the connecting part with the holder is located inside the core tube, there is no risk of the cosmetics rotating unnecessarily and protruding from the core tube and breaking, and when connecting with the holder, the core tube and outer tube are It can be guided and connected reliably. Furthermore, the use of a core chuck with claw pieces not only provides excellent protection for fragile cosmetics, but also because each claw is guided by a sliding groove, making it possible to reliably make the cosmetics come out and disappear from the core tube. It is something. Furthermore, if connecting portions are provided at both ends of the holder, it has various excellent effects such as being able to use two types of cosmetics at the same time.
