Antibacterial pressure-resistant double-layer cream bottle and material preparation method thereof

Abstract

The invention relates to an antibacterial pressure-resistant double-layer cream bottle and a material preparation method thereof, which are designed for solving the technical problems that the structural design of a bottle body and a cover body in the existing similar products is not good enough and the material preparation method needs to be improved. A bottle body of the double-layer cream bottle comprises an inner bottle and an outer bottle. The bottle is characterized in that the outer diameter of the inner bottle below the outer threads of the inner bottle is provided with a protruding ring diameter, the outer diameter of the inner bottle below the ring diameter is provided with a buckling ring with the diameter smaller than the ring diameter, the outer diameter of the inner bottle below the buckling ring is provided with outer rotation stopping ribs which are smaller than the buckling ring in diameter and evenly distributed at equal intervals, and the outer diameter of the innerbottle on one side is provided with protruding bottle positioning ribs. A protruding ring buckling rib is arranged on the inner diameter of a bottle opening of the outer bottle, the inner rotation stopping ribs which are evenly distributed at equal intervals are arranged on the inner diameter of the bottom of the outer bottle, a bottle positioning groove is formed in the inner diameter of the outer bottle on one side of each inner rotation stopping rib, and when the bottle positioning ribs of the inner bottle are inserted into the bottle positioning grooves of the outer bottle, the buckling ring of the inner bottle is buckled with the ring buckling ribs of the outer bottle, and the outer rotation stopping ribs of the inner bottle are meshed with the inner rotation stopping ribs of the outer bottle.

Description

technical field [0001] The invention relates to a cream bottle, which is an antibacterial and pressure-resistant double-layer cream bottle and a material preparation method thereof. Background technique [0002] Cream bottle refers to a bottle used for storing and withdrawing body cream or moisturizer. The body and cap of this type of bottle are generally made of plastic, and some of the bottles are made of glass. Existing general cream bottle structure is comparatively simple, is made up of bottle body, bottle cap, and the bottle mouth of bottle body in the bottle cap is provided with cap sheet, and bottle cap comprises outer cap, inner cap and gasket; As disclosed in Chinese patent documents Application number 201910490668.1, application publication date 2019.09.03, invention name "antibacterial degradable cream bottle and its material preparation method". However, the production and assembly of the inner and outer bottle structures of the above-mentioned products and sim...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the above-mentioned deficiencies, the purpose of the present invention is to provide a rotary buckle type antibacterial and pressure-resistant double-layer cream bottle and its material preparation method, so that it can solve the problems of the inner and outer bottles and lids of the existing similar products. The structure design of the inner and outer caps is not good, which makes the production and assembly of the bottle body and the cap body more inconvenient, and the material ratio and preparation method of the bottle body and the cap body need to be improved.
