Abstract

The invention relates to a squeezing device for a container for storing liquid and belongs to the field of daily life. The squeezing device comprises a container body, an upper cover, a bottom cover, a second piston, a second one-way valve, a pressing rod mechanism, an air inflow bin and a liquid storage bin. The upper cover is connected with an opening of the container body. The bottom cover is connected to the bottom of the container body. The second piston is arranged in the container body. The second one-way valve is connected with the container body. The pressing rod mechanism comprises a hollow pressing rod, a liquid outlet and a first one-way valve. One end of the hollow pressing rod is connected with the first one-way valve. The other end of the hollow pressing rod is connected with the second one-way valve. The liquid outlet is communicated with the first one-way valve. An air inflow hole is arranged on the bottom cover. The air inflow bin is formed between the bottom cover and the second piston. The liquid storage bin is formed between the second piston and the second one-way valve. The squeezing device is reasonable in structure, convenient to use, low in cost, capable of guaranteeing that liquid in the container does not make contact with air, safe and reliable.

Description

technical field [0001] The invention relates to a device, in particular to a squeezing device for storing liquid in a volume, which belongs to the field of daily life. Background technique [0002] In daily life, there are many items, such as fresh milk, cough syrup, antipyretic Merrill Lynch, shampoo, body wash, etc., all have different shelf life, but the existing packaging has the same problem, for example, antipyretic The shelf life of Merrill Lynch is three years. Before it is opened and used, there is no problem in using it within the three-year shelf life. However, after a bottle of newly produced antipyretic medicine Merrill Lynch is opened and eaten, the medicine in the bottle will be directly damaged by opening the bottle cap. In contact with the air, if the bottle of antipyretic medicine Merrill Lynch is not used up in a short time, it needs to be consumed after half a year or a year. Whether you can continue to eat it, if you throw it away, it will cause a certa...
