Practical bottle neck

Abstract

The invention relates to a practical bottle neck, which comprises a bottle neck body, an air inlet and a liquid outlet, wherein the bottle neck body is provided with a spacer, the air inlet and the air outlet are arranged on the spacer, the lower end of the air inlet is connected with an air inlet pipe, the air inlet hole of the air inlet pipe is communicated with the air inlet. The practical bottle neck has the characteristics of low cost and easiness in controlling the flow rate and the flow of the liquid outlet.

Description

technical field [0001] The invention relates to a bottle mouth, in particular to a practical bottle mouth. Background technique [0002] In today's liquid product packaging and sales market, although the container bottle has undergone great changes and diversification has appeared, the bottle mouth still uses the bottle mouth that was thirty years ago or even longer. At the same time as it is perfect, I have noticed that this kind of bottle mouth that does not keep pace with the times, its various shortcomings are exposed to everyone's eyes, such as: when pouring liquid, the liquid spouts irregularly, the flow rate is uneven, and the flow rate is not easy to control , the residue at the bottle mouth will not flow back into the bottle, but will flow out of the bottle to pollute the environment. In the prior art, in order to overcome the above-mentioned defects, a bottle mouth with an air inlet and a liquid outlet is installed on the mouth of the bottle, and a bottle mouth wi...

[0002] In today's liquid product packaging and sales market, although the container bottle has undergone great changes and diversification has appeared, the bottle mouth still uses the bottle mouth that was thirty years ago or even longer. At the same time as it is perfect, I have noticed that this kind of bottle mouth that does not keep pace with the times, its various shortcomings are exposed to everyone's eyes, such as: when pouring liquid, the liquid spouts irregularly, the flow rate is uneven, and the flow rate is not easy to control , the residue at the mouth of the bottle will not flow back into the bottle, but will flow out of the bottle to pollute the environment

In the prior art, in order to overcome the above-mentioned defects, a bottle mouth with an air inlet and a liquid outlet is installed on the mouth of the bottle, and a bottle mouth with a function similar to a one-way valve is arranged at the air inlet, such as the 201420382617 that the applicant has applied for recently. The scheme recorded in .X, although the above-mentioned technical scheme can avoid the phenomenon that the liquid outlet and the intake air alternately grab the lane, but the structure of the one-way valve is complicated and the cost is high, which is suitable for high-end products, but for ordinary low-end products with fierce competition in the market , which increases the cost of the product, while high energy consumption and high cost are not conducive to marketing and acceptance by consumers
