An apparatus and method utilizes a forming machine which includes a mandrel and forming plate each shaped to conform the paperboard and/or corrugated material blank passing through the mandrel into the desired configuration for a leak-proof tray. The blank includes a layer of a suitable paperboard and/or corrugated material, and a layer of leak-proof plastic or paper material disposed over one side of the corrugated material. The corrugated material includes cutouts at each corner of the blank that enable the sides and ends of the blank to be folded relative to one another. The paper material continuously overlaps the surface of the corrugated layer and these cutouts to provide a continuous leak-proof barrier layer within the formed tray and at the corners of the blank when folded to form the tray, as the paper material is folded over itself to form a bellows corner in the tray.

A self-contained continuous PDQ package system is provided for shipment and display of products. The PDQ package includes four adjacent sections of preferably corrugated material each with an inner facing and an outer facing surface, with a cut out within the bottom flap panel. Within the cut out, there is a section where an adhesive is placed adhering the inner facing portion of body panel and the inner facing of a section of bottom of the outer panel flap and adjacent mid-section panel. The self-contained continuous PDQ package system also provides an erectable reinforced shoulder to facilitate display of products in a stack of cartons.

A tamper evident feature for a container is provided. The tamper evident feature may include a locking tab connected to a wall panel or cover panel of the container and a receiving slot provided on the opposing cover panel or wall panel of the container. The locking tab may include an outer terminal edge and a slit extending laterally across the locking tab. The slit may provide a cut edge extending partially across an intermediate portion of the locking tab and allow for a tab end portion to bend relative to the remainder of the locking tab. The receiving slot may include a receiving slit defined into the cover panel of the container and configured to receive the locking tab. The receiving slit may provide a receiving edge that engages with the cut edge of the locking tab to secure the cover panel in a closed position.

A packing box including a box body and a cover body is provided. The box body includes a bottom plate and first side plates connected to the bottom plate. The bottom plate and the first side plates collectively encircle an accommodation space. One of the first side plates includes a first tongue piece extending out of the accommodation space. The first tongue piece includes a fixing end and a free end. The cover body includes a top plate and a second side plate. The top plate is pivotally connected to the box body, such that the top plate is adapted to be opened or closed to expose or shield the accommodation space. The second side plate includes a first inner layer and a first outer layer stacked with each other. The first inner layer has a notch, and the notch is close to one side of the top plate and corresponds to the first tongue piece. When the cover body is closed to the box body, the free end strikes the first outer layer of the second side plate to produce a sound.

A re-closable carton device is disclosed for transporting footwear and other articles. The re-closable carton device comprises a pair of opposing side panels, a base panel joined to the side panels and having a pair of opposing side flanges, and a lid closure side panel hingedly attached to the rear side panel. The lid closure side panel comprises female recess areas which engage with the male locking tabs of the front side panel. Specifically, the male locking tabs engage the female recess areas such that the male locking tabs partially enter the female recess areas and press against the female recess areas to distort the front flap of the lid closure side panel and to produce an audible sound or click when the carton device is fully closed to alert a user that the carton device has been reclosed adequately.
