As shown in fig. 1 to 3, an environment-friendly plastic bottle includes:

the bottle comprises a bottle body 1, a bottle cap 2 and a plastic film 3, wherein the bottle body 1 is of a cylindrical structure, the plastic film 3 is sleeved in the bottle body 1, an accommodating space 4 is formed between the plastic film 3 and the inner wall of the bottle body 1, and colored gas is filled in the accommodating space 4.

Some beverages, medicine need the light-resistant to be handled, therefore, when filling the beverage of light-resistant, during the medicine, the plastic bottle is dark, the sepia, be not convenient for the user to observe the beverage in the plastic bottle, the surplus of medicine, perhaps when the user pours liquid into the plastic bottle of dark, also be inconvenient for observe the liquid level in the plastic bottle, consequently, when accommodation space 4 between plastic film 3 and the inner wall of body 1 fills colored gas, the liquid that holds in the plastic bottle extrudes plastic film 3, and make plastic film 3 contradict with the inner wall of plastic bottle, colored gas is extrudeed in accommodation space 4, through observing the position of colored gas, thereby can judge the height of liquid level in the plastic bottle.

The working principle is as follows:

the utility model discloses in the use, when accommodation space 4 between the inner wall of plastic film 3 and body 1 fills colored gas, hold liquid extrusion plastic film 3 in the plastic bottle to make plastic film 3 contradict with the inner wall of plastic bottle, colored gas is extruded in accommodation space 4, through observing the position of colored gas, thereby can judge the height of liquid level in the plastic bottle.

It should be understood that the above-described embodiments are merely illustrative of the preferred embodiments of the present invention and the technical principles thereof.
