Abstract
A system is provided for automatic consecutive opening and dispensing thermoplastic grocery or retail product bags of the T-shirt type while providing for supporting consecutive bags in an open position and for facilitating easy removal of the consecutive loaded bags. The system includes a pack of bags and a rack of the type having outwardly extending support arms and a retaining means for receiving the bag pack by mounting the bag handles on the support arms of the rack through apertures therein and mounting a detachable bag mounting tab on the rack retaining means. Each of the bags has disengageable adhesive between each bag which has a predetermined severance strength greater than the severance strength of the mounting tabs. The rack support arms define a predetermined resistive force in laterally-extending outer portions against sliding of the bags therealong which is greater than the severance strength of the adhesive. Upon removal of each loaded bag from the rack, (1) the adhesive will detach between the rear wall of the loaded bag in the front wall of the next consecutive bag since the resistive force against sliding of the bags along the outer portions of the support arms is greater than the severance strength of the adhesive between the bags and (2) the adhesive before detaching will pull the next consecutive bag from the bag pack into an open loading position on the support arms by severing the mounting tab on the front wall portion of the next consecutive bag since the severance strength of the adhesive is greater than the severance strength of the mounting tabs.
