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

Abstract

The invention discloses an oil-free, glue-free and easily sliding lipstick pipe. The lipstick pipe comprises a fork, an elastic ring, a bead, a shell and a screw. The bottom of the fork is fitted withthe inner side surface of the elastic ring; the elastic ring is of a hollow structure, the top of the elastic ring is provided with a plurality of flicking outward elastic sheets arranged at intervals, a gap between adjacent elastic sheets is divided into an upper potion and a lower portion, the upper potion and the lower portion are different in size, and the top of each of the elastic sheets isprovided with an arc-shaped surface; the inner side surface of the bottom of the screw is fitted with and slidably connected with the arc-shaped surface in the radial direction; the bead is sleeved with the interior of the fork, the bead is provided with a guide column, and the guide column is matched with a guide groove in the fork; the interior of the shell is provided with inward shell bulges.The lipstick pipe can achieve the technical purposes of smartly using elasticity to design the distance between the screw and the fork, therefore satisfying easy sliding between the screw and fork, and improving service life of a product; and accordingly product quality is improved.

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
