Problems solved by technology

The lipstick is embedded in the lipstick tube, which can be turned in or out by rotation. The existing lipstick tube is not well sealed, and it is easy to cause the lipstick to deteriorate due to long-term contact with the air. At the same time, the protective sleeve on the lipstick tube is connected stably. Insufficient resistance, it is easy to fall off by itself during the carrying process, causing the lipstick to become dirty and affecting the user experience; the lipstick tube does not have enough protection for the internal lipstick paste, and it is easy to break the lipstick paste when it is dropped

Abstract

The invention belongs to the field of lipstick processing, and particularly discloses a preparation method of an integrally-formed lipstick tube. The lipstick tube comprises a rotating sleeve, a lifting sleeve and a protective sleeve. A circle of clamping groove of a sunken structure is formed in the opening end face of the rotating sleeve, a circle of clamping ring of a protruding structure is arranged on the opening end face of the protective sleeve, and the clamping ring is adaptively embedded into the clamping groove and is in threaded connection with the clamping groove. A counterweight structure and a buffer structure are arranged at the bottom of the rotating sleeve. According to the preparation method, the protective sleeve is not prone to falling off automatically, meanwhile, under the action of thread tightening, sealing rings on the joint faces of the rotating sleeve and the protective sleeve can be mutually squeezed and jacked tightly, a good sealing effect is guaranteed, and contact between lipstick paste and external air is effectively reduced; the gravity center of the whole lipstick is transferred to the bottom of the rotating sleeve, when the lipstick falls off, the buffer structure at the bottom of a counterweight bottom block touches the ground firstly, and the buffer performance is good; and the whole lipstick tube has a good antibacterial effect.

Description

technical field [0001] The invention relates to the field of lipstick processing, in particular to a method for preparing an integrally formed lipstick tube. Background technique [0002] Lipstick is a kind of lip beauty cosmetics. The main function of lipstick is to give the lips tone, emphasize or change the contours of the lips, and show more vitality and vitality. The lipstick is embedded in the lipstick tube, which can be turned in or out by rotation. The existing lipstick tube is not well sealed, and it is easy to cause the lipstick to deteriorate due to long-term contact with the air. At the same time, the protective sleeve on the lipstick tube is connected stably. Insufficient resistance, it is easy to fall off by itself during the carrying process, causing the lipstick to become dirty and affecting the user experience; the lipstick tube does not have enough protection for the internal lipstick paste, and it is easy to break the lipstick paste when it is dropped. ...
