A improved bag clamp for closing and cutting a polymer bag, said clamp comprising:
- two opposed clamp members, wherein said clamp members are movable between a closed and open condition, each one of said clamp members having an inner and an outer surface,
- a gripping means disposed on the inner surface of each one of said clamp members for gripping said bag, said gripping means including a plurality of internal ridges disposed on the inner surface of each one of said clamp members,
- each one of said clamp members possessing a mouth end for engagement of a bag surface and a grasping end for grasping by a user,
- a hinge attaching said clamp members to each other, said hinge attached to each clamp member inner surface at a location between said mouth end and said grasping end, the hinge biased by a spring clip, said spring clip possessing increased strength over spring clips in previous applications,
- each of said clamp member mouth ends possessing a lip for aiding in positioning said bag in said clamp,
- said clamp members identified as an upper clamp member and a lower clamp member,
- a cutting means disposed on the inner surface of said upper clamp member, said cutting means comprised of a cutting blade, a springboard button, and a blade guard,
- said cutting blade possessing a characteristic shape and increased sharpness such that cutting efficiency is improved over previous cutting blade designs for this application,
