Bionic leakage-proof package bottle

Abstract

The invention discloses a bionic leakage-proof package bottle which comprises a bottle body and a bottle cap. The bionic leakage-proof package bottle is characterized in that the bottle cap comprises a cap body seat, a surface cap capable of being overturned to be open is hinged to the cap body seat through a hinge piece, the cap body seat is provided with an opening, and the opening is provided with a sealing switch device capable o being turned on to form a channel when the cap body seat is extruded. The bottle body comprises a PE inner layer, wherein a PP outer layer is arranged outside the PE inner layer, the upper end face of the bottle body is provided with a bottle opening communicated with the inner cavity of the bottle body, a limiting convex block is arranged on the outer wall of the bottle opening, and a connecting ring for being connected with the bottle cap is arranged on the outer wall of the bottle opening above the limiting convex block. The invention aims at overcoming the shortcomings in the prior art, and the bionic leakage-proof package bottle is simple in structure, convenient to use, low in production cost and good in leakage-proof effect.

Description

technical field [0001] The invention relates to a bionic leak-proof packaging bottle. Background technique [0002] The traditional bottle cap generally includes a bottle cap seat and a cap body hinged on the bottle cap seat. After the cap body and the bottle cap seat are opened, if the bottle body is tipped or inverted, the liquid contained in the bottle body will be under the action of gravity. It flows out through the opening of the bottle cap, which causes waste and a lot of inconvenience to the user agent. [0003] The outer surface of the existing blow-molded bottle is basically glossy, and the high-gloss bottles in the market are produced by co-extrusion of multiple layers of different materials; the structure is complex and the production cost is relatively high. Moreover, due to the design defects of the existing high-gloss bottle, liquid leakage often occurs after being connected with the bottle cap. [0004] Therefore, the existing packaging bottles need to be f...

Problems solved by technology

[0002] The traditional bottle cap generally includes a bottle cap seat and a cover body hinged on the bottle cap seat. After the cover body and the bottle cap seat are opened, if the bottle body is tipped over or stands upside down, the liquid contained in the bottle body will fall under the action of gravity. down through the opening of the bottle cap, which causes waste and inconvenience to the user agent

[0003] The outer surface of the existing blow-molded bottles is basically glossy, and the high-gloss surface bottles available on the market are all produced by co-extruding multiple layers of different materials; their structures are complex and their production costs are relatively high

Moreover, the existing high-gloss bottle often leaks after being connected with the bottle cap due to design defects.
