Detailed Explanation For The Use of Child Resistant Caps

Function and Principle of CRC:

Child Resistant Caps, also known as child-proof caps, also it’s been called pressure screw caps. Child Resistant Caps(CRC) are generally used for healthcare product packaging, pharmaceutical product packaging, high-end food packaging, chemical packaging, cosmetics packaging, etc.;

As you can say from the name, the child safety cap and the screw cap are specially designed to protect the safety of children under the age of 12 or the elderly over the age of 65 in use, and prevent children from accidentally eating the contents of the bottle and causing injury;

The CR cap structure has a double-layer cap design, an outer cap with an inner cap. The outer top of the inner cap has occlusal teeth, and the inner top of the outer cap has a tooth groove that interlocks with the occlusal teeth of the inner cap, and there is a slight gap between the inner and outer caps. When the user presses down and rotates clockwise, the occlusal teeth and tooth grooves are engaged with each other, and the outer cap drives the inner cap to rotate and gradually tighten on the thread of the bottle mouth, which plays the role of sealing the bottle cap and the bottle mouth.

Popular Models of CRC In The Market:

At present, the popular styles in the market are square, round, triangular, oval, etc.

Common Problems and Standards of CRC:

1. The sealing effect of the screw cap is not good, and it is necessary to check whether the sealing gasket is qualified.

2. The inner and outer layers of the cap do not rotate, since the gap between the inner and outer caps is too small

3. The inner and outer layers of the cap easily fall off since the gap between the inner and outer caps is too large

4. There is a creaking sound when they screw the cap since the occlusal teeth and rodent bites do not match well.

5. There are punctate marks of occlusal teeth on the top of the cap, and the occlusal teeth are designed as a hollow structure
