CHILD-RESISTANT CLOSURE, CARTON PACKAGE, AND METHODS OF PRODUCING THE SAME

Patentradars sammanfattning

Modulpac AB's closure integrates an attachment collar, a circular spout with a circumferential locking track groove, and a rotatably mounted cap arrangement comprising an attachment ring and a hinge-linked flip cap. Child resistance is achieved by requiring simultaneous lateral compression of two opposing depression areas on the cap mantle, which resiliently ovalizes the mantle and drives the interior locking hook radially outward from the groove before the flip cap can be pivoted open. An additional safety layer derives from the cap arrangement's free rotation about the spout axis, mimicking a screw cap and discouraging children from discovering the correct opening sequence. The closure is designed for ultrasonic welding to carton (gable-top) packages and is compatible with existing screw-cap production lines.
