Description

Technical Field

[0001] The utility model relates to a cosmetic eyeliner pen tube, which is an aluminum-plastic separation eyeliner tube. Background Art

[0002] Liquid eyeliner is a cosmetic product that differs from ordinary eyeliner. It is a makeup application that uses liquid eyeliner to draw the eyeliner, and requires a liquid eyeliner brush. When using it, place the liquid eyeliner brush close to the base of the eyelashes and apply it from the inner corner of the eye to the outer corner. When drawing the upper eyeliner, use the other hand to draw the outer corner of the eye. When drawing the lower eyeliner, use one hand to hold the lower eyelid and draw, and you have a perfect makeup look. Among them, some liquid eyeliner pens use a structure similar to a straight liquid ballpoint pen, such as the one disclosed in the Chinese patent literature with authorization announcement number CN212307114U, authorization announcement date 2021.01.08, and utility model name "Antibacterial and Antistatic Liquid Eyeliner Pen." The liquid eyeliner pen on the other side is similar to liquid lip gloss, nail polish and other cosmetic products, and generally has a bottle body and a stick body, such as the authorization announcement number CN208550331U disclosed in the Chinese patent literature, the authorization announcement date 2019.03.01, and the utility model name "A roller-type liquid eyeliner pen with a liquid storage bottle"; however, the above-mentioned products and similar products rarely use a replacement structure design, and their outer diameter is smaller.

After the lower cover aluminum retaining ring and the aluminum lower cover are connected as one, the bottle, lower cover aluminum retaining ring, and aluminum lower cover are connected as one. The external thread at the bottle mouth extends out of the top cover of the aluminum lower cover. The aluminum upper cover, upper cover aluminum retaining ring, aluminum lower cover, and lower cover aluminum retaining ring are alumina components.

[0005] Positioning teeth are symmetrically provided on both sides of the first step groove on the outer diameter above the buckle rib of the bottle. The top opening of the lower cover aluminum retaining ring is flush with the first step groove of the bottle. At the same time, the positioning teeth of the bottle are engaged with the lower positioning rib on the inner wall of the lower cover aluminum retaining ring to limit the position.

[0006] A second step groove is provided on the outer diameter below the external thread at the bottle mouth of the bottle. When the bottle is fitted and fixed with the aluminum clamping spring of the aluminum lower cover, the top cover of the aluminum lower cover is fitted flush with the second step groove of the bottle.

[0007] The outer diameter below the opening of the end cover of the support bone is provided with a positioning gear ring whose outer diameter is larger than the outer diameter of the opening; the outer diameter of the cover opening of the end cover below the positioning gear ring is provided with a raised limiting edge; the support bone is fixed to the raised stamped upper spring piece in the aluminum retaining spring of the upper cover through interference fit at the opening of the end cover; at the same time, the positioning gear ring of the end cover is engaged with the upper positioning rib on the inner wall of the aluminum retaining spring of the upper cover for limiting position; the bottom cover opening of the aluminum upper cover is flush with the limiting edge of the end cover.

[0008] The utility model has a reasonable structural design, is easy to use, disassemble and replace, has a long service life, is environmentally friendly, has a good feel when used, does not require glue, and is convenient for automated production and assembly; it is suitable for use as an aluminum-plastic separated eyeliner tube, and is a structural improvement of similar products.

[0013] Now, in conjunction with the accompanying drawings, the structure and use of the utility model are further described. Figure 1-Figure 3 As shown, the eyeliner tube includes a bottle body and a rod body, the bottle body includes an inner plug 4, a bottle 5 and a lower cover assembly, the rod body includes a support bone 3 and an upper cover assembly, the end of the rod 301 at one end of the support bone is provided with a brush 6, and the end cap 302 at the other end of the support bone is connected to the external thread at the bottle mouth of the bottle through an internal thread, the bottle mouth is fixed with an inner plug 4, and the rod of the support bone is inserted into the bottle through the inner plug. There are openings symmetrically provided on both sides of the top groove at the end cover of the support bone, and the aluminum upper cover 1 of the upper cover assembly is provided with an upper cover aluminum retaining spring 2 that is fitted and fixed as one. The support bone is fixed to the protruding stamped upper spring piece 201 in the upper cover aluminum retaining spring through the concave surface of the opening of the end cover. After the upper cover aluminum retaining spring is connected to the aluminum upper cover as one, the support bone, the upper cover aluminum retaining spring and the aluminum upper cover are connected as one; the lower cover aluminum retaining spring 7 of the lower cover assembly is fitted and fixed to the bottom of the aluminum lower cover 8, and the outer diameter of the bottom of the bottle is provided with a raised snap rib 501, and the bottle is fixed to the raised stamped lower snap point 701 on the inner wall of the lower cover aluminum retaining spring in the aluminum lower cover through the snap rib. After the lower cover aluminum retaining spring is connected to the aluminum lower cover as one, the bottle, the lower cover aluminum retaining spring and the aluminum lower cover are connected as one, and the external thread at the bottle mouth of the bottle extends out of the top cover opening of the aluminum lower cover.

[0014] Positioning teeth 502 are symmetrically positioned on either side of the first stepped groove above the outer diameter of the bottle's snap rib. The top opening of the lower cover's aluminum retaining ring fits flush with the bottle's first stepped groove, while the bottle's positioning teeth engage with the lower positioning rib 702 on the inner wall of the lower cover's aluminum retaining ring to limit its position. A second stepped groove is provided on the outer diameter below the external thread of the bottle's mouth. As the bottle fits securely within the aluminum retaining ring within the aluminum lower cover, the top opening of the aluminum lower cover fits flush with the second stepped groove. A positioning tooth ring 3021, larger than the outer diameter of the opening, is provided below the end cap opening of the support frame. A raised limiting edge 3022 is provided on the outer diameter of the end cap opening below the positioning tooth ring. The support frame is secured to the raised stamped upper spring leaf within the aluminum retaining ring of the upper cover through the end cap opening. The positioning tooth ring of the end cap engages with the upper positioning rib on the inner wall of the aluminum retaining ring to limit its position, and the bottom opening of the aluminum upper cover fits flush with the limiting edge of the end cap.

[0015] To use, simply twist the wand to remove it and apply eyeliner. Once the liquid in the bottle is used up, firmly pull out the wand's upper and lower caps, then attach them to a new refill. This facilitates recycling of the aluminum and plastic materials in the eyeliner tube, allowing you to purchase a refill after use.
