This is the original design of the plastic bottle cap, no wonder some beautiful women can not unscrew it!
How are plastic bottle caps made for pennies each? Is the cap and anti-theft ring integrated when opening beverage bottles or what? Why can't some beautiful women unscrew the cap? The mystery that had been hidden in my heart for so many years was solved!
The cap is fastened on the mouth of the bottle by fitting with the mouth of the bottle, which is to prevent the leakage of the material inside the bottle and the invasion of the outside bacteria. After tightening the cap, the top of the bottle goes deep into the top of the cap to the sealing gasket. The measuring groove of the cap and the thread of the cap are in close contact with each other to provide pressure for the sealing surface. Several sealing structures can effectively avoid leakage or deterioration of substances in the bottle.
The outer edge of the cap also has a lot of strip-like anti-skid grooves, which is easy to increase friction when opening the cap.
One: two kinds of technology of plastic cap production
1. compression moulding-plastic bottle cap production process
compression moulding plastic bottle cap has no material mouth trace, looks more beautiful, processing temperature bottom, shrink, cap size is more accurate.
The upper and lower molds are closed and pressed into bottle cap shape in the mold
The cap is left in the upper mould, the lower mould is removed, the cap passes through the rotating disc, and the cap is removed from the mould in the counterclockwise direction according to the internal thread.
2 . Injection bottle cap production process
The volume of the injection mold is large, and the replacement is troublesome. The pressure of each injection mold is large, and the heating temperature of the material is high, so the energy consumption is higher than that of the plastic cap compression molding machine.
The mixed material is put into the injection molding machine, and the material is heated to about 230 degrees Celsius in the machine to become a semi-plasticized state. The material is injected into the mold cavity of the abrasive tool through pressure, and the mold is cooled and finalized.

Two: anti-theft ring (ring) production
Careful you will find that the cap also includes a security ring (ring) part. It is in the production of a good plastic cap part and then through the cutting anti-theft ring (ring), a complete cap production was completed.
Anti-theft ring (ring), is a small circle below the cap, also known as a one-time breaking anti-theft ring, unscrew the cap anti-theft ring will fall off to stay on the bottle, through this can judge a bottle of water or a bottle of drinks is complete or has been opened.
Usually we would like to think, in the packaging of the cap and the anti-theft ring (ring) is one or connected to the back? The answer is one + cap slitting
The production of a good bottle cap face in a direction of the queue, sent to the ring cut, is a tooth ring cutting knife a pull, made by the point connected with the anti-theft ring ~
Steps are as follows.
The caps are lined up in one direction and sent to the cap slitting path

The reason why the bottle cap can be very firmly sealed is closely related to its manufacturing technology and structure. So, some people ask, why many beautiful women can't unscrew plastic bottle tops?
Some people say it's a ruse. If a girl can unscrew all the bottle tops, then a guy doesn't stand a chance. What do you think? Please punch in the comments section.
