4 Claims.
The present invention relatesto containers
which are particularly adapted for the packing
wardly tapered edges. The side walls 3 and l
are provided respectively at their ends with ?aps
3a., 3b and 4a, 4b. These ?aps are formed with
of ice cream and other edible materials which are
intended to be made up in individual packages , conventional interlocking portions which engage
with each other to retain the container in as- 5

sembled or set-up condition, see particularly Fig. l
One object of the invention is to provide a rel
atively liquid-tight container capable of being
' manufactured in complete form at the box plant
so that the container may be set up by the user

without requiring any special machinery or

without use of fastening devices other than the
partsof the container itself.
A further object of'the invention is to pro
vide asimple and effective construction of con

stance, ?rst folded inwardly in assembling the
container so that they will lie inside of the as- .
sembled interlocking ?aps 3a, 6a; and 3b, 41). Due 10
to the construction just described it is apparent
that the container may be set up and retained
in condition to effectively hold the material.
Other conventional means could, if. desired, be
employed to retain the side walls in container 15
