An exemplary reusable mist sprayer according to the present invention includes a container with an opening which has double walls that is vacuum sealed between the walls to provide insulation from the atmosphere. The exemplary sprayer also includes a plunger to pump atmospheric air into the container. The plunger respectively has a hole and hollow opening at the opposing ends, the hole provides a path for atmospheric air to enter the interior space of the plunger. Enclosing the opening of the container is a removable dispenser mechanism having a protruding end adapted to receive the hollow opening of the plunger, and a flange adapted to removably seal the opening of the container. A one-way valve is associated with the protruding end, which only opens to allow the air within the interior space of the plunger to enter the container as the plunger is being pressed relative to the protruding end. A plug is associated with the hole such that the plug engages with the hole as the plunger is being pressed relative to the protruding end, and the plug disengages with the hole as the plunger is being pulled relative to the protruding end. As such, air within the plunger is trapped to be injected into the container through the one-way valve when the plunger is pressed relative to the protruding end, but when the plunger is pulled relative to the protruding end the hole is open to relieve the vacuum within the interior space of the plunger to make it easier for a user to pull the plunger.
