ABSTRACT:
A pet waste pickup device having an elongated tubular member with a pair of jaws at a lower end of the tubular member. An upper sleeve on the tubular member acts through an elongated rod passing through the tubular member to open and close the jaws by a scissor-like action. A plunger extends through the tubular member and is operable by a lower sleeve to extend between an extended and retracted position. A bag is clipped into a forward end of the plunger. A skirt portion of the bag is internally coated with an adhesive material and is provided with a strippable tape thereon. The skirt portion is folded over the blades of the jaws and the tape is removed. After the waste material is scooped up into the bag by closing the blades of the jaws, the plunger is moved upwardly to its retracted position, thereby unfolding the skirt portion of the bag from the blades and simultaneously sealing the bag. The sealed bag is then disposed of by releasing it from the forward end of the plunger.
