Claim:
An instrument for applying a predetermined amount of fluid material to a surface comprising: a fluid insert for housing fluid material having a first end and a second end, and a protruding ridge arranged on an exterior of said fluid insert between said first end and said second end; an outer casing having a hollow interior for receiving said fluid insert therein, said outer casing having a first end and a second end, and a pump actuating surface, said outer casing further including an applicator tip integrally formed with said outer casing at said first end for dispensing fluid material from said outer casing, and an interior ridge arranged within said hollow interior between said first end and said second end for securing said fluid insert within said outer casing when said protruding ridge of said fluid insert is positioned between said interior ridge of said outer casing and said first end of said outer casing; a pump arranged at said first end of said fluid insert having a pump body and a pump tip; and said fluid insert constructed and arranged to be movable within said outer casing between a stationary position and an actuated position, said pump being in an extended position when said fluid insert is in said stationary position, and said pump being in a retracted position within said pump body as a result of said pump tip being in engagement with said pump actuating surface of said outer casing when said fluid insert is in said actuated position, and said pump being operative to dispense a predetermined amount of fluid material as said fluid insert is moved from said stationary position to said actuated position within said outer casing.
