Abstract: A flat, collapsible blank which is assembled to form a box of suitable thickness and sufficient rigidity. Four panels of the same size and shape are hinged serially. Each has folding end flaps with diagonally opposed tabs and opposing bevelled corners. Further, each end flap has a slot situated such that it cooperates with and is joined by the tab on the end flap of the adjacent panel. Hence, the interlocking box has interlapping end flaps which when taken together form the top and bottom panels of the box. Additionally, each corner tab has a meshed area on the exterior surface thereof, and each slot has a meshed area on the interior surface thereof, such that the two meshed areas cooperate. These meshed areas are used to add rigidity and support to the top and bottom panels when each end flap is folded in its configuration during use. The box can also be used by children as a toy or plaything, being large enough for them to climb into.

Abstract: A carton having a tubular body with a pair of opposed sidewalls and a pair of opposed endwalls, with end panels and side panels for a closure extending therefrom. At least one end panel is hinged to an endwall and has a free edge defining a pair of spaced notches with a retention flap therebetween, thereby forming a pair of locking tabs, one at each free corner of the end panel. At least one hinged tab is struck out from each side panel. The hinged tab includes a tab hinge line and a double-ended severing line extending to spaced apart portions of the tab hinge line so as to form a tab which is swingable out of the plane of the side panel, thereby exposing a locking edge of the side panel formed by the severing line. The locking tabs of the end panel deflect the hinge tabs into the interior of the carton to form recesses in the side panels into which the locking tabs are inserted so that the locking edge of the tab engages the locking edge of the side panel.

Abstract: A medical specimen bag is made of three or more overlying sheets of clear pliable plastic material joined along three common edges to make at least two separate pockets open along a fourth edge of the sheets. One of the sheets includes an adhesive flap foldable against the exposed fourth edges of the remaining sheets for sealing all the pockets. The sealed end of the bag is torn off to regain access to all pockets.

Abstract: A blank and carton and method of carton construction for packaging ice cream or the like. The blank includes a front, bottom, rear, cover and closure flap hingedly connected in the order named. Each front bottom rear cover and closure flap includes right and left end flaps hingedly connected to its respective panel. Membrane flaps are hingedly connected to the right and left end flaps of the bottom panel for forming a lip when the carton is constructed to prevent the accidental escape of liquid from the interior of the carton.

Abstract: The polymer coated exterior of a paperboard container used to package liquid products is selectively treated with a flame or corona to raise the surface tension in the areas which are intended to accept ink while eliminating or canceling any surface treatment in the region where a pour spout fitment is to be bonded to the container.

Abstract: In a paperboard food container, especially the clamshell type used in the fast food industry, a releasably interlocking means between the container and a lid. The interlocking means includes a slot formed in the container which not only leaves a continuous, coplanar shoulder around the circumference of the container which allows complete sealing with a lid structure, but additionally provides a tab which extends above the slot, allowing the lid structure to have either a flange extending under the container tab or, in addition to the flange, a tab inserting into the slot.

Abstract: A paperboard carton of multiple compartments and leakproofness for packaging separate food items is provided. Adjacent side panels and bottom panels merge to form the corners. Diagonal divider panels extend from the corners to the opposite side panel and along the bottom panels. A pair of gusset panels are provided to reinforce the corners and to connect the side panels. Each gusset panel extends from a side panel and the adjacent divider panel. The gusset panels are overlapped and folded around the corner and sealed with thermoplastic adhesive against the adjacent side panel. The divider panel is doubled forming an inverted V. The two divider panels provide miror image triangular compartments and a trapezoidal central compartment. A cover hinged along the side panel of the central compartment between the reinforced corners is sealed to the carton along sealing flanges to close and complete the carton.

Abstract: A reusable shipping container is formed of corrugated plastic material and includes shallow, open-ended, rectangular boxes forming a bottom and a cover. The end walls and side walls of the container are formed of inner and outer sheets of corrugated plastic material in the shape of rectangular panels. The corrugations of the panels extend vertically when the container is assembled. A total of six panels form the box, two of the opposing panels form ends of the container, and on each side, two equal-sized panels are used. The panels for the sides each have a length which is less than the length of the end panels. Corrugated plastic hinge members permit the side panels to fold inwardly to overlie one another, between the first and second end panels, in a storage position of the container member; so that the container may be placed inside the base or the top for storage.
