1. A refillable spray dispenser comprises:
a bottle having a spray assembly and a compartment in fluid communication with the spray assembly; the bottle further having a bottom portion comprising:
a hollow injection rod comprising a rod fill hole, a rod injection hole, and a groove along the hollow injection rod;bottom portion walls;a first seal and a second seal;a bottom opening;a portion injection hole and a portion exhaust hole provided in the bottom portion walls; anda passage extending from the portion exhaust hole to the bottom opening, wherein, when the hollow injection rod is at a resting position, the first seal seals the passage, preventing communication of gas from the compartment to the bottom opening, and the second seal seals the rod injection hole, preventing communication of liquid from the rod fill hole to the compartment, wherein, when the hollow injection rod is in an extended position and the dispenser is being refilled, the first seal allows communication of gas from the compartment, via the portion exhaust hole and the passage to the bottom opening, and the second seal allows communication of liquid from the rod fill hole, via the rod injection hole, to the compartment, and wherein said groove allows gas to bypass said first seal since the first seal grips the entire circumference of the hollow injection rod and cannot seal the groove in the extended position. |
