Claim:
An assembly for packaging a product, said assembly comprising: a carton having a top, a bottom, and a side extending between the top and the bottom, wherein at least one of the top, the bottom, and the side comprises a movable section that is movable between a first position and a second position, the movable section being biased to the first position, the carton extends a height measured between the top and bottom of the carton, the side comprises a plurality of sides, the movable section comprises a movable section on each of the plurality of sides, each of the movable sections comprises an upper extension extending from an upper portion of the respective side along an upper fold line, and a lower extension extending from a lower portion of the respective side along a lower fold line and joined to the upper extension of the respective side along a central fold line, and each of the movable section central fold lines are located along a central longitudinal axis of the carton at a generally equal distance from the top of the carton, the central fold lines of the movable sections being spaced a greater radial distance from the central longitudinal axis of the carton in the first position than in the second position, wherein the movable sections are movable from the first position to the second position by bending the upper and lower extensions along the upper, lower, and central fold lines to move the central fold lines generally radially toward the central longitudinal axis of the carton to reduce a cross-sectional area of the carton defined between the movable sections; and a heat-shrinkable layer overlapping at least a portion of the carton for forming the carton, the heat-shrinkable layer moves the movable section from the first position to the second position when the heat-shrinkable layer is heated to come into contact with the portion of the carton.
