Abstract
A rectangular tubular carton of foldable sheet material having a sealed end closure which comprises end closure panels hinged on oppositely disposed sidewalls, which are of a size to close the open end, with the innermost one having a narrow hinged panel on its free edge which is adhesively secured to the inside face of the outermost closure panel and folded into engagement with the innermost panel and hinged dust flaps on the other two sidewalls which are notched out along the one edge to accommodate the edge panel when it is folded back onto the innermost closure panel, the dust flaps being interposed between the closure panels. In a modified form, small end panels are hinged to the outermost closure panel and secured against the outside top margins of the sidewalls which have the dust flaps.
