Apparatus for supporting and opening plastic bags

Abstract

Abstract Apparatus for both supporting a plurality of plastic bags and for facilitating the automatic opening of the bags one at a time to permit the filling of each bag. Each of the bags is provided with generally aligned apertures in its front and back bag walls. Preferably the apertures are circular and with one of larger diameter than the other. A plurality of the bags is supported on an inclined rod having a diameter only slightly less than the aperture of smaller diameter in the opposed bag walls. At the dispensing end of the support rod a flange is provided which is of such size that the aperture of larger diameter in the opposed bag walls can quite readily pass over such flange, but the opposing bag wall is held by the flange and can be removed therefrom only by distorting and distending the smaller aperture. The plurality of bags on the rod is urged toward the flange by reason of the downward sloping inclination of the support rod. Air under pressure may be fed into the support rod and issued therefrom adjacent the flange, the resulting air jet facilitating the opening of the bag.
