Abstract
A child-resistant apparatus for dispensing articles which comprises a housing for retaining a blister package wherein the housing comprises a dispensing aperture; optionally, but preferably, a blister package comprising at least one blister cell containing an article to be dispensed; and a substantially rigid backing sheet substantially co-extensive with, and substantially blocking, the dispensing aperture, such that pressure exerted on an exposed top edge of the backing sheet imparts arcuate flexure thereto and dislocation thereof from the substantially co-extensive, and substantially blocking position, to a position where the dispensing aperture is unblocked permitting the at least one article contained in the at least one blister cell to be dispensed. Release of pressure on the exposed top edge of the backing sheet relaxes flexure thereof such that the substantially co-extensive, and substantially blocking position, wherein the backing sheet substantially blocks the dispensing aperture, is restored.
