Abstract
Disclosed is a fluid dispensing system useful for applying lotions and the like comprising a substantially rigid body having a hollow interior space and a discharge hole accessing the hollow interior space. A collapsible bag, disposed within the interior space and containing a fluid to be dispensed, has an open end in fluid communication with the discharge hole where an applicator is also engaged to permit the fluid to flow from the applicator. A pressure pump for increasing the pressure within the interior space to displace the fluid out of the bag and through the discharge hole thereby causing the fluid to flow from the applicator, is attached to the body. In another practice, the fluid dispensing system comprises a squeezable body having at least one vent hole.
Claims24
A fluid dispensing system comprising:
- a squeezable body having a hollow interior space and an open end at a first location, the open end accessing the hollow interior space;
- an annular collar attached to the open end;
- a plurality of pressure sensitive containers selected from:
- (a) a plurality of collapsible bags, or
- (b) a plurality of elastic balloons, or
- (c) a combination of at least one collapsible bag and at least one elastic balloon,
- each of (a) the plurality of collapsible bags or each of (b) the plurality of elastic balloons or each of (c) the combination of at least one collapsible bag and at least one elastic balloon contains a respective fluid to be dispensed, and
- each of (a) the plurality of collapsible bags or each of (b) the plurality of elastic balloons or each of (c) the combination of at least one collapsible bag and at least one elastic balloon are disposed within the interior space, and each of (a) the plurality of collapsible bags or each (b) the plurality of elastic balloons or each of (c) the combination of at least one collapsible bag and at least one elastic balloon individually having:
- a discharge end portion,
- an outer tube disposed over the discharge end portion,
- an inner tube disposed within the discharge end portion, the inner tube in fluid communication with the respective fluid to be dispensed, the inner tube having (i) an inner tube inlet located within the respective pressure sensitive container for intake of the respective fluid to be dispensed, and (ii) an inner tube outlet from which the respective fluid to be dispensed is dispensed, the inner tube outlet disposed within the annular collar or extending above the annular collar, the outer tube configured to provide a flush fit of the discharge end portion between it and the outside surface of the inner tube.
