Description

Technical Field

[0001] This utility model relates to the field of cosmetic packaging, and in particular to a lip balm tube. Background Technology

[0002] Lip balm is an indispensable part of cosmetics. To make it convenient to use and carry, the balm is usually contained in a rotating tube. The tube can be rotated to raise or lower the balm. Rotating the tube forward will reveal the balm, while rotating it backward will hide the balm.

[0003] In some existing lip balms, the guide rail is located between the cup and the inner tube. If the cup rises too far and extends beyond the inner tube, the guide rail between the cup and the inner tube separates and can no longer guide the cup, causing the cup to fall out of the inner tube. The balm contained in the cup may not be fully utilized. Utility Model Content

[0004] The purpose of this utility model is to provide a lip balm tube in which the screw and the cup inside the tube are detachably installed. The screw can lift the cup out of the inner tube port, so that the balm inside the cup can be fully used. Secondly, the cup extends beyond the inner tube port, making it easy to disassemble and replace, facilitating resource recycling and saving resources.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lip balm tube includes a base, an inner tube, a fixing seat, a screw, and a cup. The lower end of the fixing seat is fixedly installed at the bottom of the inner cavity of the base, and the inner tube is fitted inside the base and rotatably connected to the fixing seat.

[0007] An annular baffle is integrally connected to the middle section of the inner tube. A limiting hole is provided in the center of the baffle. The limiting hole is square and penetrates the baffle.

[0008] The screw passes through the inner circumference of the fixed base and is threaded to the upper end of the fixed base. The upper end of the screw is inserted into and passes through the limiting hole one. The outer circumference of the screw slides with the limiting hole one and achieves axial rotation limiting.

[0009] A cup is installed at the upper end of the screw, and the cup is used to hold the paste.

[0010] The base is integrally connected to a base plate, and an opening is provided in the middle of the base plate. The lower end of the screw can extend through the opening to the lower side of the base plate.

[0011] An extension cylinder is fixedly connected to the lower outer periphery of the opening, and the lower end of the screw can extend into the extension cylinder.

[0012] The lip balm tube in this solution also includes a lower housing, the base is installed in the inner cavity of the lower housing, a relief groove is opened at the bottom of the inner cavity of the lower housing, and the extension tube can be partially embedded in the relief groove.

[0013] The upper end of the fixed base is provided with a threaded guide part, which is embedded in the lower end of the inner tube. A guide protrusion is integrally connected inside the threaded guide part, and a threaded groove is opened on the surface of the screw. The guide protrusion is adapted to the threaded groove.

[0014] The guide protrusions are provided in two and are aligned, and the threaded grooves are provided in two ways, which are matched with the two guide protrusions.

[0015] The cup body is detachably installed on the upper end of the screw.

[0016] The bottom of the cup body is integrally connected to a connecting part, and the surface of the connecting part is provided with parallel annular protrusions; the upper end of the screw has a limiting hole two that matches the connecting part, and the inside of the limiting hole two has an annular groove that matches the annular protrusions. The connecting part is inserted into the limiting hole two and is limited by the annular protrusions embedding into the annular groove.

[0017] The lip balm tube in this solution also includes an upper shell, an inner cover fixedly installed inside the upper shell, and the upper shell can be rotatably fastened to the upper end of the base.

[0018] The beneficial effects of this utility model are:

[0019] This invention uses a screw to rotate and push the cup body to achieve lifting and lowering, and the cup body can extend out of the inner cylinder to fully utilize the paste inside the cup body.

[0020] By using a screw with a roughly square cross-section to slide and adapt to the baffle of the inner tube, the vertical lifting guide can be realized, eliminating the lifting guide structure between the cup containing the paste and the inner tube. This allows the cup to extend out of the inner tube and continue to achieve normal lifting and adjusting.

[0021] Secondly, the screw and the cup body are detachably installed, which facilitates replacement and reuse, saving resources. Attached Figure Description
