Oil-free, glue-free and easily sliding lipstick pipe

Abstract

The invention discloses an oil-free and glue-free easily slippery lipstick tube, which comprises a fork, an elastic ring, a bead, a shell, and a spiral; the bottom of the fork is attached to the inner surface of the elastic ring; the elastic ring has a hollow structure, and the top has a A plurality of outer elastic shrapnel arranged at intervals, the gap between adjacent shrapnel is divided into upper and lower parts, wherein the size of the upper part and the lower part are different, the top of the shrapnel has an arc surface; the inner surface of the spiral bottom is in line with the above arc The shape and surface fit and form an axial sliding connection; the bead fits inside the fork, and the bead has a guide post, which matches the guide groove on the fork; the inside of the shell has a shell protrusion protruding inward. The invention can solve the technical problem of how to cleverly use the elasticity to design the distance between the helix and the fork, so as to not only satisfy the easy sliding between the helix and the fork, but also improve the service life of the product to improve the quality of the product.

Description

technical field [0001] The invention relates to a lipstick tube, which creatively designs an elastic ring on the lipstick tube. By using the elastic ring and other accessories of the lipstick tube, the effect of easily sliding the lipstick tube out without oil and glue can be realized, thereby improving The quality of the lipstick tube upgrades the lipstick tube from the original life product to a work of art, bringing a unique experience to users. Background technique [0002] Lipstick tubes have a long history. In the past, lipstick tubes were only used as daily necessities. The price was low and the quality was average. Some products even used defective products, which caused the lipstick tube to have a peculiar smell, and often caused jams due to poor fitting precision of parts, resulting in poor user experience. Because the users are women, the development trend of lipstick tubes is gradually becoming refined and high-end. Most of the current lipstick tube manufacturers...

AI Technical Summary

Problems solved by technology

Since the rotation of the fork and the screw requires both a certain torque force and a smooth hand feel, the above-mentioned lipstick tubes generally adopt the method of adding lubricant to increase the flexibility of the fork and the screw rotation, which leads to peculiar smell in the product and increased production costs. , complex process, easy to cause pollution and other deficiencies; in order to avoid the use of lubricating oil, there is a technical solution to use elastic parts to adjust the distance between the screw and the fork, but the elastic parts used are ordinary ring-shaped thin skin structures, which are used during use. Due to the concentration of force in the middle, there are abnormal noises and short service life; at the same time, the fork and the aluminum casing are combined with glue, and the glue currently used cannot guarantee non-toxic and tasteless; these will seriously affect the experience of using the lipstick tube
