Description

Technical Field

[0001] The utility model relates to a core in a cosmetic container, in particular to a core for a two-color stick-shaped cosmetic container such as a lipstick, a lip balm, a stick-shaped eyeshadow, a stick-shaped foundation, a perfume bottle, a lotion, an eyeliner, a mascara brush, a makeup brush, etc. Background Art

[0002] The contents of existing storage containers for lipsticks, etc. generally have only one color. If consumers need to use lipsticks of different colors, they have to buy multiple lipsticks, which increases the purchase cost and also causes waste of resources, and is not conducive to environmental protection and recycling.

[0003] To solve this problem, two-color lipsticks have emerged on the market, but the two-color lipsticks on the market have the following disadvantages:

[0004] As Figure 1 shown, one is to simply connect the bottoms of two lipsticks (a) and (b) of different colors together or share a bottom cover. The components of this lipstick (c) are doubled. For example, two more lids (d) are added, which does not fundamentally solve the problem of waste of resources, and the length is also doubled, which is not conducive to carrying.

[0005] As Figure 2 shown, the other is to drive the relative rotation of two driven gears (e) and (g) with a driving gear (f) to achieve the effect of one of the two middle containers (h) and (i) rising and the other falling. However, in this structure, when the two middle containers are simultaneously received into the container, they need to be kept at the same height as much as possible, which is not easy to operate. And the structure is complex, which is not conducive to cost reduction and is also easy to damage. Summary of the Invention

[0006] The technical problem to be solved by the utility model is to provide a core for a two-color stick-shaped cosmetic container with a simple structure, reliable quality and convenient operation, in order to overcome the deficiencies of the prior art.

[0007] The technical solution adopted by the present utility model is as follows: A middle core in a two-color rod-shaped cosmetic container, comprising a cosmetic storage component for storing cosmetics, and a rotating mechanism for guiding the cosmetic storage component to lift and lower with the cosmetics. The rotating mechanism is sleeved outside the cosmetic storage component and fixed by a bottom plug component. The cosmetic storage component is a cosmetic storage component having a first middle dish component and a second middle dish component for storing different-color cosmetics. The rotating mechanism is composed of an upper rotating cylinder member and a lower rotating cylinder member formed with an inner spiral groove. The lower part of the upper rotating cylinder member is fixedly connected to the upper part of the lower rotating cylinder member. Among them, the upper rotating cylinder member is connected to the first middle dish component in the cosmetic storage component for driving the lifting of the first middle dish component, and the lower rotating cylinder member is connected to the second middle dish component in the cosmetic storage component for driving the lifting of the second middle dish component.

[0008] The cosmetic storage component includes an inner cylinder member, and a first middle dish component and a second middle dish component inserted into the inner cylinder member. The first middle dish component is located at the upper end of the second middle dish component. The second middle dish component can penetrate through the first middle dish component. An integrally formed first guiding pin column protrudes outward on the outer side wall of the first middle dish component, and a second guiding pin column protrudes outward at the lower part of the outer side wall of the second middle dish component. An upper guiding groove capable of penetrating through the first guiding pin column and guiding the first guiding pin column is formed on the cylinder wall of the inner cylinder member, and a lower guiding groove capable of penetrating through the second guiding pin column and guiding the second guiding pin column is formed.

[0009] The middle core in a two-color rod-shaped cosmetic container of the present utility model has a simple production structure, reliable quality, is easy to operate, does not require a large increase in the number of components, is convenient to carry, and does not significantly increase the cost.

[0034] The following will make a detailed description of the middle core of a two - color rod - shaped cosmetic container of the present utility model in combination with the embodiments and the drawings.

[0035] As Figure 3As shown in the figure, a core in a two-color rod-shaped cosmetic container of the present utility model includes a cosmetic storage component for storing cosmetics and a rotating mechanism for guiding the cosmetic storage component to lift and lower with the cosmetics. The rotating mechanism is sleeved outside the cosmetic storage component and fixed by a bottom plug component H. The cosmetic storage component is a cosmetic storage component having a first middle dish component E and a second middle dish component F for storing different-color cosmetics. The rotating mechanism is composed of an upper rotating cylinder part and a lower rotating cylinder part formed with inner spiral grooves. The lower part of the upper rotating cylinder part is fixedly connected to the upper part of the lower rotating cylinder part. Among them, the upper rotating cylinder part is connected to the first middle dish component E in the cosmetic storage component for driving the lifting of the first middle dish component E, and the lower rotating cylinder part is connected to the second middle dish component F in the cosmetic storage component for driving the lifting of the second middle dish component F.

[0036] The cosmetic storage component includes an inner cylinder component G and a first middle dish component E and a second middle dish component F inserted into the inner cylinder component G. The first middle dish component E is located at the upper end of the second middle dish component F. The second middle dish component F can penetrate through the first middle dish component E. The cosmetics stored in the first middle dish component E and the second middle dish component F are one of lipstick, lip balm, rod-shaped eyeshadow, rod-shaped foundation, perfume bottle, lotion, and eyeliner, eyelash brush, and makeup brush. An integrally formed first guiding pin E1 protrudes outward on the outer sidewall of the first middle dish component E, and a second guiding pin F1 protrudes outward on the lower part of the outer sidewall of the second middle dish component F. An upper guiding groove G1 that can penetrate through the first guiding pin E1 and guide the first guiding pin E1 is formed on the cylinder wall of the inner cylinder component G, and a lower guiding groove G2 that can penetrate through the second guiding pin F1 and guide the second guiding pin F1 is formed. The upper guiding groove G1 is located above and communicated with the lower guiding groove G2. The upper guiding groove G1 and the lower guiding groove G2 are connected by a communicating groove with a width smaller than the widths of the upper guiding groove G1 and the lower guiding groove G2.

[0037] The first middle dish component E includes a first main middle dish E3. A first cosmetic tray E4 for storing a kind of color cosmetics is formed convexly upward on the upper end surface of the first main middle dish E3. A through hole E2 that penetrates up and down and can penetrate through the second cosmetic tray F2 in the second middle dish component F is formed on the upper end surface of the first main middle dish E3 on one side of the first cosmetic tray E4. The first guiding pin E1 protrudes outward on the outer side surface of the first main middle dish E3. The first guiding pin E1 penetrates through the upper guiding groove G1 and is embedded in the first inner spiral groove B1 of the upper rotating cylinder part.

[0038] The second middle dish component F includes a second main body middle dish F3, and a second cosmetic tray F2 is formed on the upper end surface of the second main body middle dish F3 and can penetrate the through hole E2 on the first main body middle dish E3. The second guide pin F1 is formed on the outer surface of the second main body middle dish F3 and protrudes outward. The second guide pin F1 penetrates the lower guide groove G2 and is embedded in the second inner spiral groove C1 of the lower rotating cylinder.

[0039] The upper rotating cylinder member includes an outer cylinder member and a middle cylinder member B. A circle of anti-slip convex ribs A1 protruding inwardly are formed on the inner side of the middle part of the outer cylinder member A, and a circle of anti-slip grooves B2 recessed inwardly are formed on the outer side of the lower periphery of the middle cylinder member B. When the middle cylinder member B passes through the inner side of the outer cylinder member A, the anti-slip convex ribs A1 on the inner side of the outer cylinder member A are embedded in the anti-slip grooves B2 on the outer side of the lower periphery of the middle cylinder member B, so that the middle cylinder member B can only rotate in the outer cylinder member A and cannot be separated from the outer cylinder member A upward. The inner circumferential surface of the middle cylinder member B is formed with a first inner spiral groove B1 capable of embedding a first guide pin E1 formed on the first middle dish member E. When the middle cylinder member B rotates, the first guide pin E1 moves up and down along the upper guide groove G1 formed on the inner cylinder member G under the drive of the first inner spiral groove B1, thereby driving the first middle dish member E to move up and down along the middle cylinder member B.

[0040] The lower rotating cylinder member includes a lower cylinder member C and a connecting member D, the connecting member D is sleeved on the upper part of the outer side of the lower cylinder member C, and the two are interference fit, and the upper ports of the lower cylinder member C and the connecting member D are aligned, and the inner side surface of the lower cylinder member C is formed with a second inner spiral groove C1 that can be embedded in the second guide pin F1 formed on the second middle dish member F. When the lower cylinder member C rotates, the second guide pin F1 moves up and down along the lower guide groove G2 formed on the inner cylinder member G under the drive of the second inner spiral groove C1, thereby driving the second middle dish member F to move up and down along the lower cylinder member C, and the lower rotating cylinder member is fixedly connected by inserting the upper connecting member D into the outer cylinder member A and forming an interference fit with the outer cylinder member A.

[0041] The middle cylinder component B and the outer cylinder component A can rotate freely relative to each other, and because the outer cylinder component A is fixed to the connecting component D, the middle cylinder component B and the lower cylinder component C can rotate freely relative to each other. When the middle cylinder component B rotates, the lifting and lowering of the first middle dish component E can be controlled. When the outer cylinder component A rotates, the lifting and lowering of the second middle dish component F can be controlled.

[0042] The fixedly connected upper rotating cylinder part and lower rotating cylinder part are sleeved outside the inner cylinder part G, wherein the inner peripheral surface of the lower cylinder part C in the lower rotating cylinder part and the outer peripheral surface of the bottom plug part H connected to the bottom end of the inner cylinder part G are in interference fit. The lower part of the lower cylinder part C is fixedly connected to the bottom plug part H, so that the inner cylinder part G cannot be disengaged from below the lower cylinder part C.

[0043] The first middle dish part E, the second middle dish part F, the outer cylinder part A, the middle cylinder part B, the lower cylinder part C, the inner cylinder part G, the connecting part D and the bottom plug part H are made of metal materials or resin materials.

[0044] An O-ring I for increasing or eliminating the adjustment of the rotation value and for sensory use is provided between the rotating parts, and the material of the O-ring I is one of resin, rubber, silica gel and metal.

[0045] As Figure 4 shown, it is a schematic diagram of the overall structure of a two-color rod-shaped cosmetic container of the present utility model in which a cosmetic is stored in a middle core.
