A recloseable package for holding one or more articles, the package being repeatedly configurable between a closed position and an open position, the package comprising:
- a backing card having a front surface, two side edges and a bend line, the bend line dividing the backing card into a card upper portion and a card lower portion, the bend line defining an axis of rotation, the backing card defining a first plane when the package is in the closed position;
- and
- a one piece blister adhered to the backing card and comprising a blister body and a flange extending laterally away from a periphery of the blister body, the flange having a width and terminating in a flange edge, the blister having a planar cutline located entirely within a second plane perpendicular to and intersecting the first plane at the bend line when the package is in the closed position, the cutline extending substantially continuously across the blister body, the cutline dividing the blister into a blister upper portion and a blister lower portion;
- the flange comprising a flange upper portion extending laterally from the blister upper portion and a flange lower portion extending laterally from the blister lower portion, the blister and the backing card defining an interior for holding the one or more articles, the flange comprising a formed hinge located on either lateral side of the blister body, each formed hinge comprising a three-dimensional contoured body extending longitudinally the width of the flange and tapering from a first end located at the flange edge to a second end located at the blister sidewall, the blister upper portion and the blister lower portion being connected at the formed hinges in both the closed and open configurations;
- wherein
- in the closed position, the blister upper portion is adhered to the card upper portion, the blister lower portion is adhered to the card lower portion, and the lower edge of the blister upper portion and the top edge of the blister lower portion abut along the cutline;
- and
- in the open position, the backing card remains intact but is in the bent position, the blister upper portion remains adhered to the card upper portion, the blister lower portion remains adhered to the card lower portion, and the lower edge of the blister upper portion and the top edge of the blister lower portion are spaced apart to allow access to the one or more articles.
