ABSTRACT:
A liquid collection apparatus includes a container for storing a liquid sample removably connected to a lid. The lid includes an opening therethrough to permit liquid to pass into the container for storage. A closure disk is operably mounted on the lid to selectively close the opening after a predetermined amount of liquid has entered the container. The closure disk is biased towards the closed position, and is retained in an open position by an operable latch which is connected to the bottom of the lid. A trigger operably mounted on the bottom of the lid has a float connected thereto which will pivot a trigger arm as the level of liquid within the container raises, thereby operating the latch to disengage from the closure disk and permit the closure disk to rotate to a closed position, thereby sealing the sample within the container. The container is supported in an upright orientation within a holder frame which is selectively and adjustably mounted to a ground engaging post, thereby permitting the container to be positioned at the desired position above the ground.
