PE plastic bottle

Abstract

The invention discloses a PE plastic bottle. The invention provides the PE plastic bottle capable of judging whether the bottle is screwed. The bottle comprises a bottle cap and a bottle body, the bottle cap is provided with a bottle cap mark, the bottle body is provided with a bottle body mark, and when the bottle cap is screwed tightly on the screw body, the bottle cap mark corresponds to the bottle body mark. By pre-setting the bottle cap mark and the bottle body mark on the bottle cap and the bottle body, after the bottle cap is screwed and the resistance is felt, the bottle cap is screwedto make the bottle cap mark correspond to the bottle body mark so that the right degree of tightness can be achieved, and the degree of sealing is well grasped during packaging and using. A pluralityof the bottle body marks and the bottle cap marks can be set to form a region to correspond, thereby satisfying a buffer region of thread screwing.

Description

technical field [0001] The invention relates to a PE plastic bottle. Background technique [0002] Most of the current beverages and liquids used in daily use are packaged and stored in PE plastic bottles, and the bottle caps need to be tightened during packaging and use to prevent the liquid from leaking out. Due to the characteristics of the thread fit between the bottle cap and the bottle body, if it is too tight, it will easily damage the thread, and if it is too loose, the liquid will easily leak out, so the bottle cap needs to be screwed just right. When packaging, the bottle cap is mainly tightened by the machine. The machine itself has the exact torque, while the ordinary PE plastic bottle has no reference point for the twist angle, which makes the machine unable to judge whether the cap is tightened under the corresponding torque; usually people are screwing the cap When it is used, it can only be determined by the feeling of tightness. Therefore, after receiving r...

Problems solved by technology

Due to the characteristics of the thread fit between the bottle cap and the bottle body, if it is too tight, it will easily damage the thread, and if it is too loose, the liquid will easily leak out, so the bottle cap needs to be screwed just right.

When packaging, the bottle cap is mainly tightened by the machine. The machine itself has the exact torque, while the ordinary PE plastic bottle has no reference point for the twist angle, which makes the machine unable to judge whether the cap is tightened under the corresponding torque; usually people are screwing the cap When it is used, it can only be determined by the feeling of tightness. Therefore, after receiving resistance, some people choose to continue to tighten, while others do not, resulting in over-tightening or over-loosening.

Therefore, ordinary PE plastic bottles lack a reference for judging
