Description

A portable liquid-filled bottle

technical field

The utility model relates to the field of bottle caps, in particular to a portable liquid-filled bottle for preventing special medicines from being swallowed by children.

Background technique

At present, the commercially available portable liquid bottle is composed of a press (spray head) assembly and a carrying bottle body, which is basically for one-time use. After the liquid in the bottle is used up, the bottle body has no use value and can only be discarded. Most of them are made of plastic materials, and discarding them will easily cause environmental pollution, which is not conducive to environmental protection. Disposable items are inherently uneconomical for both producers and consumers and result in a significant waste of production materials. Although choosing a large bottle of packaging can reduce the above-mentioned disadvantages, when the user chooses a large bottle of liquid for use, it is inconvenient to carry, which is also a headache for users and producers. The utility model with the patent application number 201110219030.8 provides a portable liquid filling bottle for cream, which includes a bottle body and a pressing assembly arranged at the mouth of the bottle. A replenishing mechanism is provided at the bottom of the bottle body. The replenishing mechanism includes a replenishing conduit. The lower port of the conduit leads directly to the outside of the bottle, the upper port of the supplementary conduit leads directly to the inside of the bottle, and there are also servo pistons. This utility model solves the problem of recycling liquid bottles with poor fluidity such as cream, but the components of this utility model are complicated for liquid bottles with strong fluidity, and the vacuum structure of the piston greatly reduces the stability of the bottle. sex.
