As a form of packaging, spray bottles are becoming more and more popular in our daily life. Many toner plastic bottles and cosmetic plastic bottles use nozzle type. Generally, PET plastic bottles and PE plastic bottles are the main ones, which are different from traditional bottle caps. The liquid packaged in the spray bottle is presented in the form of a backlog spray, which greatly facilitates people. For some products that need to be coated, the packaging can be more humanized by spraying.
For a plastic spray bottle, how to judge its advantages? We think there are the following aspects.
First: The nozzle design of the nozzle of the spray bottle packaging. The liquid particles sprayed by a good spray bottle must be fine and uniform, which must be judged first. Especially medical packaging, even spraying, is more scientific and accurate for the control of medication.
Second: At that time, it was whether the nozzle of the spray bottle was convenient to squeeze, because if it took a lot of effort, it would definitely be unpopular with girls.
Third: Whether the tube in the nozzle of the spray bottle can squeeze out the liquid in the spray bottle every time without leaving residue is also a key point.
It turns out that there is a press suction mechanism in the hand sanitizer bottle, which is mainly composed of a catheter, a liquid inlet valve, a spring, an exhaust valve, a piston, a liquid outlet pipe, and a liquid storage barrel.
A spray bottle works the same as a piston pump. Use the movement of the piston to discharge the air in the liquid storage tank, and generate a difference in internal and external air pressure. The liquid rises under the action of air pressure and is discharged from the liquid outlet pipe. When the liquid outlet pipe is pressed by hand, the spring is compressed to close the liquid inlet valve. At the same time, as the piston moves down at this time, the exhaust valve opens, and the liquid in the liquid storage barrel flows out from the liquid outlet pipe; When the spring is released, the spring returns to its original natural state, so that the piston moves upward, the exhaust valve closes and the inlet valve opens. Under the action of external atmospheric pressure, the liquid enters the liquid storage barrel from the catheter through the liquid inlet valve. In this way, the piston reciprocates up and down in the cylinder, constantly sucking out the liquid in the bottle. If it cannot be sprayed out, it is recommended to check whether the small hole at the nozzle is blocked, dredge the hole, or remove the nozzle and soak it in hot water for five minutes before installing it.
The principle of the spray bottle is to pressurize the liquid in the bottle, and spray the liquid into extremely fine water particles under the high pressure system. Therefore, when the spray cannot be sprayed out, do not handle it casually, so as not to cause an explosion and cause an accident. When the spray cannot be sprayed out, it is recommended to follow the steps below:
1. First check whether the nozzle is blocked by foreign matter. If clogged, use a toothpick or needle to unclog the nozzle. Remember to cover the spray after use to prevent dust from sticking to the nozzle.
2. Check the nozzle to see if it is stuck. If the nozzle is pressed too hard, the nozzle may not automatically return to its original position after use. Pull the nozzle to the same height as the original nozzle, and the nozzle can be used again after recovery.
3. If the inside of the nozzle is blocked, you can remove the nozzle, soak it in hot water for about 5 minutes, then install the nozzle and resume normal use.
