<p>A bag dispenser, for separating and dispensing a series of plastic bags where one end is attached to the top of the next bag by perforation lines with a slot therebetween. The series of bags are dispensed from a device comprising a wire frame formed into channels to support the core that the series of bags are rolled onto. The channels allow the core to rotate in place but restrict its linear movement to the vertical direction. The dispenser has two braking devices, a braking bar underneath the roll of bags and a pair of fingers that are attached to the channels to engage the core. The braking bar is positioned transversely to the series of bags so that it supports them. The pair of fingers does not engage the core until the number of bags on the core has decreased and the core has begun to descend. The two braking devices work in combination to retard the rotation and dispensing of the bags and thus to apply a tension to the series of bags. Attached to the frame is a separator with, preferably, a symmetric projection on its end. The projection will engage the slot regardless of whether the bags are drawn over or under the projection. Additionally, the separator is preferably coiled in its midsection to function as a spring. As the user pulls on the bags, a tension is created by the braking devices and the user to deflect the separator which remains deflected until the projection engages the slot. Thus, when the separator engages the slot, the separator recoils through its normal position to facilitate the separation of the two bags.</p> |
