    Abstract: The present disclosure relates to a temperature regulated, pressure activated liquid scent dispenser. The pressure in the interior of the container may increase as ambient temperature increases. A release structure of the container may release a portion of the liquid scent once a threshold pressure or threshold amount of pressure build-up is reached in the interior of the container. A method comprises filling the interior volume with a liquid scent so that the interior volume also includes a volume of air, suspending the dispenser over a ground surface, and dispensing the liquid scent from the interior volume through the release structure. Due to an increase of pressure of the volume of air, and upon reaching a threshold air pressure, the release structure releases a portion of the liquid scent from the interior volume. Applications may include dispensing animal attractant or repellent.

The container has a body that has a storage chamber for storing the substance and a head portion for holding the valve assembly. The valve assembly includes a valve body and a valve seat surrounded by a flexible outer cover that includes a valve portion. A seam between the valve portion and valve seat form a one-way release valve wherein a portion of the seam remains closed when the substance is dispensed. To dispense the substance, pressure is applied to the body forcing the substance into the valve assembly, which in turn, controls the flow and release of the substance without exposing the remaining substance to the external atmosphere; thus, the sterility of the storage chamber and remaining substance is maintained, and the shelf life of the substance is increased.
