Background technique

Washing bottles are required in some mineral processing, chemistry, biology and other laboratories, as well as in primary and secondary school chemistry laboratories for routine experiments. At present, the commonly used washing bottle is generally a polyethylene washing bottle, which is composed of a bottle cap, a bottle body, a cleaning tube, a nozzle, etc. When the bottle is used for a long time, the bottle needs to be squeezed, so that the water flow will enter the nozzle along the cleaning tube for washing. There are following deficiencies in the flushing of this extrusion method. One is that it is difficult to effectively flush by extrusion when the amount of water in the bottle is small. Sometimes it is necessary to squeeze the bottle body to deform before flushing with water. The mouth is easy to leak air, which affects the normal flushing; the second is to use the extrusion method, the rebound ability of the plastic bottle will be reduced after a certain period of use, and the use effect is far inferior to that of the new bottle, which will affect the normal flushing.
