2 Claims. (01. 229-14)
This invention relates to improvements in car
tons and packages.

~ It is the primary object of the invention to pro
vide a satisfactory carton and package for the
opening of the carton in a manner which will not
break the foil wrapper. Other objects of the in
vention will be more apparent from the follow

The false wall structure provides adequate sup
port for the liner while the molten cheese is being
poured into the carton. As indicated in Fig. 1, 50
the carton has two ply end walls throughout at
the time the cheese is being poured. This is with
out consideration of the foil or ?lm, which does
not contribute to the strength of the package but,
on the contrary, requires support. When the
cheese is poured, the foil or ?lm liner is folded 55
above the cheese and the cover panel i8 is folded
across the top, and the end panels 23 and 28_ and
the front cover panel 19 are glued to the box
ally to the assembly of the package, the wrapper
being wholly depended on, in this suggested or

proper.
