such a container blank which is so constructed that the
container may be set up from the blank readily and with

done, the two end members 32 on the front section 16 of

When the top
section 10 or lid of the crate is closed, the end assembly
formed by the two end members 32 at each end of the
crate is supported by the inner faces of the cleats 20 and
22 around all four of its edges, lending considerable
strength to the end assemblies.‘ As will be understood,
the end members ‘32 are incorporated integrally into the
container blank as it is formed in the stapling machine.
They thus add nothing to the time of producing the con

is folded into crate form, in the manner illustrated in

permit their notches ‘50d to be interengaged in the man

From the foregoing description it will be appreciated
that the aforementioned and other desirable objects of the
invention have been achieved. However, it should be
emphasized that the particular embodiments of the inven
