ABSTRACT:
A flap positioning assembly of the type primarily designed to dispose the inner flap in substantially conventional containers into a position relative to the exterior flap so that stapling or otherwise securing of the flaps may be facilitated. A support frame includes a base plate and outwardly extending support arms having a clamp arm movable relative thereto by means of an orienting shaft capable of being manipulated to allow the clamp arm to be positioned in a clamped and non-clamped relation to the flaps of the container. Connecting linkage elements movably interconnect the orienting shaft to the base plate and a biasing element is interconnected to the plurality of linkage elements in a manner which biases the orienting shaft and the connecting clamp arm into either its clamped or non-clamped position so as to accomplish a substantially locking facility of the clamp into clamped relation with the flaps of the container wherein the flaps are disposed between the undersurface of the base plate and the clamp arm.
