Abstract
A child resistant package is made from paperboard, cardboard or other foldable sheet material. The package includes an outer sleeve having a closed end and an opposed open end and an inner sleeve, telescopically received within the outer sleeve. The inner sleeve has a closed end adjacent the open end of the outer sleeve. The inner sleeve is joined to the outer sleeve by a frangible connection. The package further includes a selectively releasable lock between the inner sleeve and the outer sleeve for preventing withdrawal of the inner sleeve from the outer sleeve after the frangible connection between the inner sleeve and the outer sleeve has been broken. An opening tab is formed in the outer sleeve and is configured to break the frangible connection between the inner and outer sleeves when the tab is released from the outer sleeve and to provide an opening in the outer sleeve to provide access to the inner sleeve such that the inner sleeve may be pressed inwardly in order to release the releasable lock between the inner and outer sleeves.
