Fluid delivery mechanism
The present invention provides a fluid transfer fitment for controllably retaining a fluid in a reservoir in a leak-tight manner. This fluid transfer fitment can be used with a variety of fluid delivery mechanisms. The fluid transfer fitment has a cap portion, an engaging segment, a fluid transfer check valve and a vent check valve. The fluid transfer check valve of the fitment is located within the engaging segment of the fitment. The present invention also provides fluid delivery mechanisms, which can be used with a cleaning implement. The fluid delivery mechanisms can be used with a fitment having a cap portion, an engaging segment and a fluid transfer check valve.
1. A fluid transfer fitment, said fitment comprising:
a cap portion having a first fluid transfer opening;
an engaging segment for engaging a receiving member of a fluid delivery mechanism, wherein said engaging segment extends from said first fluid transfer opening of said cap portion and wherein said engaging segment comprises a wall defining a cavity and a second fluid transfer opening in fluid communication with said first fluid transfer opening; and
a fluid transfer check valve for controllably preventing a fluid from flowing through said fitment, wherein said fluid transfer check valve is connected to said engaging segment and wherein at least a portion of said fluid transfer check valve is located within said engaging segment; said fitment comprising a fluid filled reservoir having substantially rigid walls and having a finish portion wherein said cap portion is releasably attached to said finish portion and wherein said fluid filled reservoir is inverted;
wherein said cap portion comprises a vent opening in fluid communication with the outside atmosphere and a vent valve in fluid communication with said vent opening; wherein said fluid transfer check valve controllably closes said first fluid transfer opening in a substantially leak-tight manner;
and wherein said fluid transfer check valve controllably closes said second fluid transfer opening in a substantially leak-tight manner.
