Abstract
A carton for packaging two layers of stacked flanged tubs. A top panel overlies the tops of the upper tubs and a layer board lies between the two layers. Reinforcing flaps connected to the layer board are adhered to the side panels of the carton. The side panels contain openings through which portions of the tub flanges protrude. The bottom edge of the lower openings engage the underside of the tub flanges when lifting the package to thereby support the lower tubs.
Claims8
A package, comprising:
- upper and lower aligned articles, each article having a bottom portion, a top portion and a flange extending outwardly from the top portion;
- a layer board between the upper and lower articles, the layer board being in contact with the bottom portion of the upper article and the top portion of the lower article;
- a top panel connected to opposite side panels by fold lines, said side panels terminating at a location below the flange of the lower article and above the bottom of the lower article;
- the side panels including upper and lower openings through which portions of the flanges of the upper and lower articles extend;
- said top panel including outwardly extending tabs at least partially covering the outwardly extending flange of the upper article and said layer board including outwardly extending tabs at least partially covering the outwardly extending flange of the lower article, the tabs of said layer board extending through the lower openings in the side panels;
- and
- means for connecting the side panels to the layer board.

A two-piece blank for forming a carton for packaging upper and lower aligned articles, each article having a bottom portion, a top portion and a flange extending outwardly from the top portion, comprising:
- one of the blank pieces being comprised of a central top panel section connected by fold lines to side panel sections, the side panel sections containing openings located so as to receive portions of the flange of the lower article in a carton formed from the blank, said side panel sections being dimensioned to terminate below the flange portion of a lower article in a carton formed from the blank and above the bottom of said lower article in a carton formed from the blank;
- the top panel section fold lines being interrupted by outwardly extending slits which, when the top panel section is folded along the top panel section fold lines, create openings In the side panel sections located so as to receive portions of the flange of the upper article in a carton formed from the blank;
- the other blank piece being comprised of a central layer board section connected by fold lines to reinforcing flaps, the layer board section being designed to lie between the upper and lower articles in a carton formed from the blank, in contact with the bottom portion of the upper article and the top portion of the lower article;
- and
- the layer board section fold lines being interrupted by outwardly extending slits which, when the layer board section is folded along the layer board section fold lines, create openings in the reinforcing flaps located so as to receive portions of the flange of the lower article in a carton formed from the blank, said top panel section including outwardly extending tabs at least partially covering the outwardly extending flange of an upper article in a carton formed from the blank and said layer board section including outwardly extending tabs at least partially covering the outwardly extending flange of a lower article in a carton formed from the blank, the tabs of said layer board section extending through the openings for the lower article flanges in said side panel section in a carton formed from said blank.
