Claim 1
Independent Claim 300 words
A lightweight, portable carton packing station fixture for retaining the side and end bottom flaps of cartons of different sizes in their infolded position without adjustment to facilitate filling of the carton; comprising: (a) a longitudinally extending base plate means; (b) a pair of longitudinally extending flap retaining flange members extending upwardly from the longitudinal center axis of a carton filling portion of said base plate means, said flap retaining flange members include infeed end portions which are wedge shaped and incline downward towards said base plate means, said flap retaining flange members incline downwardly towards the longitudinal axis of said plate means at which point the inner edges thereof turn downward and then outward a short distance so as to form a securing flange portion to secure said flap retaining flange; (c) said flap retaining flange members being spaced a short distance from said base plate means so as to permit receipt and retension of a corresponding side bottom flap therebetween while the upper surfaces of said flap retaining flange members prevent downward movement of a corresponding end bottom flap such that the side and end bottom flaps are retained in their infolded position so as to permit filling of the carton; (d) said flap retaining flange members having infeed ends which terminate a distance from the infeed end of said base plate means so as to form a carton set-up and support portion integral with said base plate means; and (e) a carton set-up plate member rigidly secured to the upper surface of said carton set-up and support portion, said carton set-up plate member having a centering flange extending upward therefrom along the center axis thereof for serving as the sole means for centering of the carton prior to its being received by said flap retaining flange members.
