1. A resealable pack comprising:
- a gusseted bag, having an open end at its top, within a relatively rigid outer envelope in the form of a box having a bottom and at least two sets of opposing sidewalls having bottom edges affixed to the box bottom;
a first movable part having a top edge, two side edges and a bottom edge, and an inner and an outer face surface, the bottom edge being affixed to a top edge of a first of said sidewalls of the box;
a second movable part having a top edge, two side edges and a bottom edge, and an inner and an outer face surface, the bottom edge being affixed to a top edge of a second of said sidewalls of the box which opposes the first sidewall;
a first and a second moveable member each having two outer faces and two edges, one edge of the first and second movable members being affixed to the first and second movable parts, respectively, the other edge of the first and second movable members being affixed to the first and second sidewalls, respectively, such that when each movable member is in a closed position, the outer faces, sidewall and movable part define a deformable parallelogram, one face of each movable member being bonded to an outer face of the open end of the gusseted bag at a distance below the top of the bag, the faces of each movable member being of a length such that said one face of each closes and seals the bag when in a closed position; and
a movable flap having a top edge and a bottom edge, the bottom edge being affixed to and extending from the top edge of the first movable part, the flap being of a length such that when in a closed position and folded over it extends to the bottom edge of the second movable part.

2. A resealable pack comprising a relatively rigid outer envelope encompassing a flexible gusseted inner bag having an open end wherein the outer envelope comprises:
-
a first wall and a second opposing wall, each wall having an inner face and an outer face and a top edge and a bottom edge; a base bottom interconnecting the bottom edge of each wall; two open lateral sides between the walls, the walls being movable such that the top edges of each wall are capable of being in proximate communication one with the other in a closed position such that the top edge of the second wall is in communication with the inner face of the first wall with the bag therebetween; an elongated reciprocably movable flap portion extending from the top edge of the first wall having an inner face to which an outer face of the open end of the bag is bonded such that when the walls are brought into proximate communication, the flap is turned down and the bag is folded over the outer face of the second wall such that the flap folds and squeezes the faces of the bag together over the outer face of the second wall, the flap further having an extension protruding downward and outward from the interface between the flap and the first wall at the top edge of the first wall; and a reciprocably movable element portion extending upwardly from the outer face of the first wall and below the extent of the extension of the flap such that the flap extension and flexible element cooperate to keep the flap in open and closed positions. - View Dependent Claims (3, 4, 5, 6)
