Bag clamp
First Claim
1. A clamp for closing a polymer bag, comprising:
- a pair of opposed clamp members wherein said clamp members are movable between a closed and an opened condition, each one of said pair of clamp members having a long axis and an inner and an outer surface;
a hinge attaching said pair of clamp members, said hinge biasing each one of said pair of clamp members into a closed condition; and
means disposed on the inner surface of each one of said clamp members for gripping said bag, said gripping means including a blade disposed on the inner surface of one of said pair of clamp members and an opposed recessed anvil, disposed on the inner surface of the other one of said pair of clamp members, whereby said blade is urged against said recessed anvil to help grip said polymer bag, said gripping means further including a plurality of ribs disposed parallel to said long axis and located on the inner surface of each one of said pair of clamp members.

Abstract
A clamp for closing a polymer bag, including a pair of opposed clamp members wherein said clamp members are movable between a closed and an opened condition, each one of said pair of clamp members having a long axis and an inner and an outer surface. A hinge attaches the pair of clamp members and biases the clamp members into a closed condition. In holding a bag in a closed condition, a blade disposed on the inner surface of one of the clamp members is urged by the hinge against and an opposed recessed anvil, disposed on the inner surface of the other clamp member. In addition, a plurality of ribs disposed parallel to the clamp member long axis and located on the inner surface of each one of said pair of clamp members aid in gripping the bag within the clamp by intercalation of the ribs of one clamp with those of the other clamp. During the bag opening process, the ribs stretch the bag material for effective cutting when the material is moved past the blade.

14. A device for opening a polymer bag, comprising:
-
a pair of clamp members wherein said clamp members are movable between a closed and an opened condition, each one of said pair of clamp members having a lip for engagement of a bag surface, each one of said pair of clamp members further having an inner and an outer surface;
a hinge attaching said pair of clamp members, said hinge biasing each one of said pair of clamp members into a closed condition; and
bag cutting means disposed on the inner surface of each one of said clamp members for cutting a bag, said cutting means including a blade disposed on the inner surface of one of said pair of clamp members and an opposed recessed anvil, wherein said anvil is disposed on the inner surface of the other one of said pair of clamp members whereby said blade abuts said anvil when said clamp members are moved to a closed condition, said blade including an edge for cutting said bag when said bag is drawn through said device. - View Dependent Claims (15, 16, 17)
