Abstract
The dispensing bottle includes a dispensing head with an air inlet allowing ambient air to enter an opening of a reservoir portion of the bottle, and a filter member that fits over and seals the opening of the reservoir portion of the bottle for filtering the ambient air entering the bottle to prevent contaminants from entering the reservoir portion of the bottle along with ambient air.
Claims20
A bottle for dispensing a sterile liquid, comprising:
- a reservoir portion having an interior chamber and an opening to the interior chamber;
- a dispensing head that attaches to the opening of the reservoir portion, the dispensing head having a liquid outlet port for dispensing the sterile liquid from the bottle, a dip tube received in the interior chamber of the reservoir portion, the dip tube including a liquid inlet port connected in fluid communication with the liquid outlet port, and an air inlet port for allowing ambient air to enter the opening of the reservoir portion to equalize pressure in the bottle reservoir after liquid is dispensed from the bottle;
- and
- a filter member that fits over and seals the opening of the reservoir portion of the bottle, the filter member having two planar sides, a dip tube hole therethrough for receiving and sealing around the dip tube, and at least one vent hole therethrough, said at least one vent hole of said filter member being covered on at least one of said two planar sides of the filter member by a membrane filter.
