Patent ID: 7000491

Claim:
A fully submersible liquid sampling device comprising, in combination, a. a tube having a top and bottom and a hollow inside; b. a slotted sleeve attached to the bottom of the tube and containing at least one slot that allows liquid to enter inside the tube from the bottom; c. a stopper slidably positioned inside the slotted sleeve, where the stopper can be moved from a position that allows liquid to enter the bottom of the tube to a position that prevents liquid from entering the tube; d. a shaft operatively connected to the stopper to control the positioning of the stopper, where the shaft is centrally positioned within the hollow and is slidably associated with at least one cross brace; e. a sampling port is connected near the bottom of the tube and is in liquid communication with hollow inside of the tube; f. flaps connected to the top of the tube that are adapted to automatically close upon retrieval of the sampling device when fully submerged in a body of liquid; g. a first line connected to the tube for lowering of and fully submerging the device in a body of liquid; and h. a second line connected to the shaft for repositioning the stopper within the slotted sleeve.
