Structure of Plastic Child Resistant Caps

A child resistant cap assembly for a bottle is disclosed comprising an inner cap and outer cap. When an external pressure is applied to the outer cap, the teeth on the outer cap engage with the inner cap. While engaged, the cap assembly is rotated in a counter clockwise direction to unfasten or unscrew the cap assembly from the bottle.

  • An outer cap having hinges extending from a bottom surface of the outer cap to a top of an inner cap, wherein the hinges are vertical inclined projections angled between 45 degree to 60 degree from the bottom surface of the outer cap which form an arc-like shape around the bottom surface of the outer cap positioned every 90 degrees;
  • The hinges provide a distance between the outer cap and inner cap in a resting position;
  • An inner cap having at least one undercut along an inside rim of the inner cap;
  • Inner cap teeth extending in a vertical direction along an outer periphery of the inner cap; and outer cap teeth extending in a vertical direction along an inside of the outer cap inner periphery walls;
  • A ratio of the inner cap teeth to outer cap teeth is 2:1;
  • The inner cap teeth and outer cap teeth have angled edges;
  • The distance is about 3 mm between the bottom surface of the outer cap and the top surface of the inner cap and the distance is reduced to the other distance which is about 1 mm when a pressure is exerted on the cap assembly compressing all of the hinges in an engagement position which engage the inner cap teeth and outer cap teeth.
