Anti-bacterial pressure-resistant vacuum dropper combination bottle and material preparation method thereof

Abstract

The invention relates to an anti-bacterial pressure-resistant vacuum dropper combination bottle and material preparation method thereof. The anti-bacterial pressure-resistant vacuum dropper combination bottle is designed for solving the technical problems that a dropper bottle and a vacuum bottle are difficult to combine and use individually in existing congeneric products, and the material matching and preparation method of part of parts need to be improved. One end of the combination bottle is a vacuum bottle, the other end of the combination bottle is a dropper bottle, and a large piston isarranged in a vacuum bottle body of the vacuum bottle; according to the key point, a cover ring of an inner cover between the vacuum bottle and the dropper bottle sleeves the edge groove opening of the vacuum bottle body, meanwhile a buckle rib of the inner cover is fastened with a buckle groove of the vacuum bottle body, a vertical rib of the inner cover is fastened with a vertical groove of thevacuum bottle body, the buckle rib and the vertical rib of the inner cover are arranged on the middle ring surface, an upper ring surface is arranged on the upper part of the middle ring surface, thecover ring, the buckle rib and the upper ring surface of the inner cover are sequentially decreased, and the upper ring surface of the dropper bottle is located on the inner wall of the upper part ofthe vertical groove of the vacuum bottle; and the nozzle part of a dropper nozzle of the dropper bottle is in cone convex from the outer ring opening towards the middle, a dropper hole is formed in the middle, and the dropper hole of the dropper nozzle abuts against a gasket of the inner cover.

Description

technical field [0001] The invention relates to a combination bottle for cosmetics in which a vacuum bottle and a dropper bottle are combined, and is an antibacterial and pressure-resistant vacuum dropper combination bottle and a material preparation method thereof. Background technique [0002] The vacuum bottle refers to a container that can isolate the gas from the external temperature or the container that isolates the external bacteria. The vacuum bottle sold on the market is composed of a cylinder into an ellipsoid container and a piston placed at the bottom. Its working principle is to use the contraction force of the spring, and prevent air from entering the bottle to form a vacuum state, and use atmospheric pressure to push the piston at the bottom of the bottle forward. For example, the application number disclosed in the Chinese patent literature is 201720689852.5, the date of authorization announcement is 2018.08.03, and the name of the utility model is "environm...
