Longitudinal extensions of the outer panel of a double-walled insert closure box form tabs to opposite sides of an open-ended tubular sleeve of a rectangular cross-section having opposed longitudinal spaced end walls within which rectangular, parallelepiped, hollow insert closure boxes are inserted.

Longitudinal extensions of the outer panel of a double-walled insert closure box form tabs to opposite sides of an open-ended tubular sleeve of a rectangular cross-section having opposed longitudinal spaced end walls within which rectangular, parallelepiped, hollow insert closure boxes are inserted. Narrow elongated slots within the sleeve end walls and the box end walls extending parallel to the outer panel, insertably receive an integral lug at the terminal end of the tabs. The lugs have laterally opposed projections forming a barb of a width in excess of the length of the elongated slots to frictionally lock the insert closure box to the tubular sleeve when the extensions are bent at right angles to the outer panel and the lugs bent at right angles thereto and passed through the aligned slots. Insert closure boxes at respective ends of the tubular sleeve, are preferably formed of folded cardboard sheet material precut as a single box blank from a sheet of cardboard. The open-ended tubular sleeve may be formed transparent flexible plastic sheet material.

A tubular display package comprising: an open-ended flexible sheet material sleeve of rectangular cross-section including laterally opposed side walls and longitudinally opposed end walls, at least one outer folded sheet material, hollow insert closure box of rectangular, parallelepiped form defining an outer box section including; spared inner and outer panels of rectangular plan form, laterally opposed side walls and longitudinally opposed end walls, said closed, hollow box inserted within an open end of said sleeve, tabs integral with said insert closure box outer panel and extending longitudinally beyond the outer box section end walls, at opposite ends thereof, and those of said sleeve and overlying the same, and being of a width corresponding to that of the outer box section end walls, said two end walls of said tubular sleeve and said box insert end walls each having a narrow slot therein, proximate to an open end of said tabular sleeve and extending parallel to the outer and inner, panels of said insert closure box, and each of said tabs terminating at an end remote from said insert closure box outer wall in a lug of a width generally equal to the length of said slots, the slots of corresponding box insert end walls and tubular sleeve end walls being aligned each said tab being bent at right angles to the outer box section outer panel, extending parallel to and in contact with the outside surface of the tubular sleeve end wall and said lug being bent at right angles inwardly of said tubular sleeve end wall and passing through said aligned slots and being in frictional engagement at least with said outer box section inner panel end wall bearing said slot, upon passage therethrough.
