Abstract: A reclosable blister container in which a backing card is slidably and removably retained in the blister without requiring staples or adhesives. The blister includes elongated grooves on opposite sides thereof that slidingly receive the backing card. The blister includes a step that is preferably curved, which facilitates slidable entry of the backing card into the blister. Protrusions may be formed in the blister that extend into corresponding openings in the backing card in order to further retain the backing card within the blister. The present invention provides a more attractive and more economical alternative to prior art “flange-folded” products.
