AI Technical Summary

Technical Problem

Existing leak-proof cosmetic pump bottles lack connection stability and sealing performance when subjected to heavy impacts or shaking, and the sealing blocks are inconvenient to replace, leading to cosmetic leakage and material waste.

Method used

The design employs fixed and mounting components. Through the cooperation of sliders and slots, the rebound effect of the first spring is used to improve connection stability. The slider slides in the slot and engages with the slot to prevent the bottle cap from separating. Through the cooperation of insert rods and abutment rods, the compression effect of the second spring is used to facilitate the replacement of the sealing block, saving time and effort.

Benefits of technology

It improves the connection stability and sealing of cosmetic pump bottles, prevents cosmetic leakage, simplifies the replacement process of sealing blocks, and reduces material waste.

Abstract

The utility model relates to the technical field of cosmetics, concretely to a leakproof cosmetic pressing bottle, including pressing bottle main part, the top end of pressing bottle main part is connected with the bottle cap. The utility model discloses, through setting fixed assembly, hold the bottle cap and push, the slider fixed on the inner wall of bottle cap slides in the sliding slot along with the bottle cap, hold the bottle cap and rotate when sliding to the bottom of sliding slot, make the slider move to the depth of sliding slot, the clamping block fixed in the depth of sliding slot produces extrusion under the movement of slider, the first spring drives the clamping block to move in the installation groove along with the extrusion of clamping block, when the clamping groove moves to the clamping block, because the clamping groove is a slot, cannot extrude the clamping block, the first spring loses the rebound of extrusion, make the clamping block connect in the clamping groove, prevent the bottle cap from meeting the heavy impact or the shake and lead to the pressing bottle main part and the bottle cap separation, improved the stability and the leakproofness of connection.
