Abstract

A blister and package system made of a blister card and an outer package with unique interacting locking mechanisms. The blister card or strip is inserted into the outer package or sleeve and locks immediately without having to further process the outer package or the blister card or strip. The user is able to expose the blisters from the outer package by disengaging the lock. The blister card or strip includes a formable, pliable sheet material, into which one or more individual cavities or blisters are formed. The separated cavities are loaded with product and sealed with one or more layers of puncturable or tearable sheet material, such as aluminum foil. The blister card or strip contains a plastic rivet assembly that forms an interference mechanism. The rivet is trapped by an internally formed panel and stopped by a catch flap included in the outer package.
