Structure and design principle of child resistant cap

Child resistant caps are common child resistant screw caps and pull-on caps. It is mainly a functional bottle cap designed for the contents of bottle packaging containers that are not suitable for children to touch or eat.

The structure design of the child resistant cap is based on the intelligence and strength characteristics of children under the age of five, so that it is difficult for children to master the method of opening the cap in a short time, or know how to open the cap, but it is difficult to open the cap due to insufficient hand strength. . The purpose of designing the child resistant cap is to prevent ordinary children under the age of 5 from opening the package within a certain period of time from the packaging structure, so as to prevent children from accidentally taking certain drugs,

Accidents in which household chemicals and chemical products damage health or even endanger life occur. The obvious feature of the structure of the child resistant cap is that it can prevent children from opening the bottle cap with a simple structure and low cost, and is convenient for adults to use.

Design principle of child resistant bottle cap:

1. The structure requires a more complex opening action that is difficult for children to complete in a short time (usually 5 minutes). Such as 2 linked actions, a set of combined actions.

2. This structure requires a certain strength, that is, the strength that children under the age of 5 do not have, such as children's grip strength is only about 140N. The durability of the force is also poor, so it is difficult to open those bottle cap structures that require sufficient grip or a certain endurance to open.

3. The bottle cap is marked with text to indicate the opening method, while children under the age of 5 have almost no ability to recognize text, and adults can open it smoothly through prompts.
