Child Resistant Caps (CR Closures) FAQ

    Why are Child Resistant Caps necessary?


     Some medical products contain material that can be potent if taken by children. For an example, Iron as a food supplement, can be harmful to children if taken in large quantities. For this reason, pharmaceuticals and food supplements that can harm children should be packed in a Child Resistant Packaging. 



    How do Child Resistant Caps work?


    Child-resistant caps are designed to require two actions in order to open them, such as pushing down while turning. This mechanism is difficult for children to perform, while still being relatively easy for adults.



    How Child Resistant Caps are tested to be child resistant? 


     There are two international standards that define the way a child resistant should be tested before it can be sold and defined as child resistant. 

    ISO 8317:2017 is the standard that is commonly used in Europe while FDA 1700 is the American standard. These standards are quite similar and basically they define a test where a group of children of a certain range of age is given the child resistant packaging and observed to see how many children of this group succeeded in opening the packaging. This standard is conducted by a few international laboratories that preform the test on a specific child resistant cap, according to the standard instructions and guidelines. 

    Make sure to ask your caps supplier for a certificate proving their caps to be tested and approved as child resistant, according to one of the above mentioned standards. 


    Are Child Resistant Caps required with tamper resistant band?


    Usually Child Resistant Caps are not required with tamper-resistant band or ring. It should be noted that tamper evident is a different feature than child resistant. While a child resistant cap or packaging is a cap that can not be opened by children. A tamper evident cap or packaging is a cap that has an indication that it has been opened such as: a tear off band, a ring, a liner etc. 

    A child resistant cap usually will not have a tamper evident feature, although some child resistant caps do have that. A tamper evident cap (Such as caps used for beverages) will not necessarily be child resistant. 



    How to open a child resistant cap?


    To open a child-resistant cap, first read the instructions on the label or packaging to determine the specific type of cap and opening mechanism. Then, use the required actions to open the cap, such as pushing down and turning (used mainly in pharmaceutical applications), squeezing and pulling (used mainly in household products).

    When were child resistant caps introduced on bottles?


    Child-resistant caps were first introduced on prescription drug bottles in 1967, following the passage of the Poison Prevention Packaging Act in the United States. The act required that certain household substances and prescription drugs be packaged in child-resistant containers.



    Who invented the child resistant cap?


     The child-resistant cap was invented by Dr. Henry Breault, a toxicologist and researcher at the University of Michigan, in collaboration with the Packaging Corporation of America. The invention was prompted by the rising number of child poisonings from household products in the 1950s and 1960s.
