(57) A six-sided or parallelepiped carton and a blank (11) therefor is disclosed. The
carton is formed by folding the die-cut blank of a generally rigid, unitary blank
of a polymeric material, in wich a major portion of the thickness of the blank preferably
comprises an expanded polymeric material, at least some of the corners at one end
of such carton being self-sealed by webbed areas or gussets (35, 36, 37 and 39), which
comprise portions of such blank but which may be of reduced thickness relative to
the major portions of the remainder thereof, and a die-cut blank which is adapted
to be formed into such a carton.
The gussets are formed in areas at the closed ends of slots (31, 32, 33 and 34) extending
partially between flaps (22, 23, 24 and 25) connected to main panels (12, 13, 14 and
15) of the carton and blank at fold lines (26, 27, 28 and 29 respectively).
The other end of the arton may be similarly formed and sealed or may conveniently
be provided with a reclosable pour-out spout.
