Abstract
A reclosable hinged blister card package wherein peripheral flanges on the clear plastic blister are adhered to a paperboard card which in one embodiment is suitably cut-scored along the adhered areas to allow defined ply separation of the card for opening the blister. A hinge line is formed in the card above the bottom flange to allow hinged opening of the blister. An opening tab formed on the blister overlays an opening in the card. Locking ears on the opening tab are adapted to be pushed through the cut-out opening to lock the blister in reclosed position. Another version of the package provides reclosure and locking with pressure sensitive adhesive on the side peripheral flanges of the blister which adheres to adhesive on the underlying portions of the card.
Claims12
A reclosable hinged blister card package, comprising:
- (a) a paperboard card having a front surface and a back surface, bottom, top and side edges, and an internal edge defining an opening in said card;
- (b) a plastic blister having a raised product holding portion having bottom and side edges, and a peripheral flange at the sides and bottom of said product holding portion, said peripheral flange being adhered to the front surface of said card;
- (c) opening tab means on said plastic blister and extending over at least a portion of said opening in said card and adapted to be pushed through said opening when said blister is reclosed for locking said blister in its reclosed position;
- (d) cut score lines in the front surface of said card and extending partially through the thickness of said card along the inner and outer edges of the portions of said peripheral flange at the sides of said product holding portion, whereby said blister may be lifted by said opening tab means with confined ply separation of the paperboard card at the portions thereof which are adhered to the side portions of said peripheral flange without breaking the bond between said flange and the front surface of said paperboard card;
- and
- (e) a hinge line in said card formed along the bottom edge of said product holding portion and extending to the outside edges of said peripheral flange, and cuts formed in said card extending along the outside edges of said side peripheral flange portions from the bottom edge of said card to the ends of said hinge line, whereby said plastic blister can be swung open about said hinge line.

A reclosable hinged blister card package, comprising:
- (a) a paperboard card having a front surface and a back surface, bottom, top and side edges, and an internal edge defining an opening in said card;
- (b) a plastic blister having a raised product holding portion having bottom and side edges, and a peripheral flange at the sides and bottom of said product holding portion, said peripheral flange being adhered to the front surface of said card with one side edge of said flange at one of the side edges of said card;
- (c) opening tab means on said plastic blister and extending over at least a portion of said opening in said card and adapted to be pushed through said opening when said blister is reclosed for locking said blister in its reclosed position;
- (d) cut score lines in the front surface of said card and extending partially through the thickness of said card along the inner and outer edges of the portions of said peripheral flange at the sides of said product holding portion except along the one side edge of said flange which is at one of the side edges of said card, whereby said blister may be lifted by said opening tab means with confined ply separation of said paperboard card at the portions thereof which are adhered to said peripheral flange without breaking the bond between said flange and the front surface of said paperboard card;
- and
- (e) a hinge line in said card formed along the bottom edge of said product holding portion and extending to the outside edges of said peripheral flange, and a cut formed in said card along the outside edge of said side peripheral flange portion not at the edge of said card, said cut extending from the bottom edge of said card to the end of said hinge line, whereby said plastic blister can be swung open about said hinge line.
