Description

Technical Field

[0001] The utility model relates to the technical field of beauty and makeup, in particular to a double-head brush tube. Background Art

[0002] The double-headed brush tube can be configured and sold together with different products according to user needs, such as eyelash grafting glue, removal gel, mascara, eyeliner, etc., which is convenient for eye makeup and removal. The existing double-headed brush tube containers on the market are reverse double tubes, that is, the brushes (or tube bodies) of the double-headed tubes are set in reverse; when placed vertically, the liquid in the upper tube body flows back and back, and it is easy to leak if the lid is not closed tightly. After using the product solution in the current tube body, it is necessary to tighten the lid of the current tube section, and then reverse it to the other end, and let the backflowing side stand for a while before continuing to use it, otherwise it will be easy to accumulate too much solution at the lid and cause overflow, causing inconvenience in use. Therefore, the existing double-headed brush tube is very awkward and inconvenient to use, which violates the natural habits of users in use, and when users view product information, there are also problems such as reversed content and difficulty in identification, which is easy to open and read incorrectly. In addition, since the two ends of the double brush tubes on the market are fixed, users can only passively choose two tubes of solution with fixed combinations, and cannot choose and match the grafting solution suitable for their own eyelashes according to their own needs. Utility Model Content

[0003] The utility model aims to provide a double-head brush tube to solve the problem that when the brush head and brush tube are placed vertically in the prior art, the upper tube body is inverted and liquid leakage is easy to occur.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A double-headed brush tube comprises a first cover, a composite tube section and a second tube body, wherein the first cover, the composite tube section and the second tube body are detachably connected in sequence; the first cover is provided with a first brush head, one end of the composite tube section is provided with a first tube body for storage, the first tube body is used to accommodate the first brush head and is sealedly connected to the first cover; the other end of the composite tube section is provided with a second cover for sealingly connecting to the second tube body, the second cover is provided with a second brush head, and the second brush head is used to extend into the second tube body.

[0006] In the above-mentioned double-headed brush tube, the composite tube section is provided with two functional areas, one is used as the first tube body, which is used to store the product solution like the external second tube body, and the other is used as the sealing cover of the second tube body, with a second brush head; the first cover is used to seal with the end where the first tube body of the composite tube section is located and extend the first brush head into the first tube body; the end where the second cover of the composite tube section is located is used to seal with the second tube body and extend the second brush head into the external second tube body; when the first cover, the composite tube section and the second tube body are connected in sequence, the first brush head and the second brush head are arranged in the same direction, and accordingly, the tube openings at both ends for storing the product solution are also arranged in the same direction.

The joint between the first tube body 21 and the second cover 22 will not rotate with it, and the structure is stable and easy to use. When disassembling, just push or pry it apart in the opposite direction.

[0035] The double-headed brush tube provided in this embodiment has two tubes in the same direction, which avoids the phenomenon of product solution backflow and helps solve the problem of overflow and leakage. At the same time, the double-tube same-direction design conforms to the natural use habit of humans from top to bottom, and there is no need to reverse when using it, which makes it easy to identify product information and provides a good user experience.

[0036] Example 2

[0037] This embodiment 1 also provides a double-headed brush tube. Compared with embodiment 1, the difference of this embodiment mainly lies in the structure of the male and female snap joint at the junction of the first tube body 21 and the second cover 22. Specifically, an annular convex strip 212 is circumferentially arranged on the side wall of the convex head 211 at the bottom of the first tube body 21, and a positioning groove 214 is arranged at the bottom of the convex head 211. The structural shape of the positioning groove 214 can be a triangular prism, a cubic column, a square funnel, etc. In this embodiment, a square funnel shape is preferably set to facilitate guidance and positioning; a positioning column 224 for fitting with the positioning groove 214 is arranged in the groove 221 of the second cover 22, and the positioning column 224 and the positioning groove 214 are connected by mortise and tenon to achieve circumferential limitation, so as to prevent the first tube body 21 and the second cover 22 from rotating relative to each other in the circumferential direction. Furthermore, five card point protrusions 222 are evenly arranged circumferentially on the inner side wall of the groove 221, which are used to fit with the convex strip 212. When assembling the first tube body 21 and the second cover 22, first align the positioning groove 214 at the bottom of the first tube body 21 roughly with the positioning column 224 at the top of the second cover 22, then press the first tube body 21 downward with force, and assemble the convex head 211 into the groove 221. The convex strip 212 on the convex head 211 passes over the clamping point protrusion 222 to lock in place, and the top surface of the positioning column 224 can fit exactly with the bottom surface of the positioning groove 214. When disassembling the composite pipe section 2, the two tube bodies can be directly opened or pried apart.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
