  • Patent number: 9403632
    Abstract: A fluid dispenser; in one non-limiting embodiment the fluid dispenser of the invention comprises: a housing, a hand pump, at least one bag, and a stem stabilizer. The housing defines an interior chamber and a housing wall. The housing wall defines at least one air-vent hole for ingress of air. The hand pump has a stem which extends downward into the interior chamber of the housing. The at least one bag is located in the interior chamber and is sealed except for being connected to the at least one air-vent hole. Negative pressure is created in the interior chamber when fluid is extracted from the interior chamber via the hand pump, this causes air to flow into the at least one air bag and thus the fluid inside the interior chamber is kept separate from the air entering the at least one air bag.

  • Patent number: 8727184
    Abstract: A container and associated dispenser for liquid is configured to dispense residual liquid from the container after the bulk of liquid has been dispensed from the container. This is accomplished by having a conical projection on the bottom of the container which causes residual liquid to flow into a gutter defined by the wall of the container and the surface of the conical projection. A dip-tube is connected to the dispenser and is rotatable in order to revolve the open free end of the dip-tube to access any circumferential location in the gutter in order to pick up residual liquid.

    Abstract: Traditional hand pump dispenser found in common household cannot dispense 100% of the product it contains in the container. This invention relates to devices, systems and methods for dispensing, distributing or delivering a substance from the dispensing container. More particularly, the invention relates to a device and method for dispensing a liquid (e.g., a cleaner, disinfectant, deodorizer, moisturizer, medication, etc.) more effectively. Furthermore, the invention allows users to access the dispensing material when the hand pump cannot be primed due to the level of the fluid in the container. This new dispensing bottle will eliminate waste to almost zero.

  • Patent number: 8286837
    Abstract: A power assembly for dispensing product from a container includes a pump mechanism and an energy storage mechanism. The pump mechanism includes a rotatable actuating collar connected through an escapement mechanism with a drive screw with an externally threaded shaft engaged with internal threads in a piston. Rotation of the collar reciprocates the piston to store energy in the energy storage mechanism and to draw product into a pump chamber from which the product is dispensed. An actuator is connected with a stem valve to open it when the actuator is depressed, enabling the energy storage mechanism to push the piston back to its at-rest position to force product from the pump chamber and ready it for another dispensing cycle. Disengagement of the escapement mechanism when the actuator is depressed prevents rotation of the actuating collar. Different energy storage mechanisms can be interchangeably attached to the pump mechanism.

  • Patent number: 6708852
    Abstract: A mechanically pressurized aerosol dispensing system comprising a cap which houses a piston, an actuator moveably attached to the cap, forming together with the cap a dispensing head assembly, and an expandable elastic reservoir. The system is fitted over a standard container holding a liquid product, and includes a dip tube assembly to draw liquid into the dispensing head assembly, where the contents are released through the dispensing head assembly, via the aerosol nozzle and valve. A twist of the threaded cap raises a piston, thereby opening a charging chamber within the dispensing head assembly. This creates a vacuum with the resulting suction pulling the product up through the dip tube to fill the charging chamber. Twisting the cap in the opposite direction lowers the piston in a downstroke which closes the charging chamber, forcing the product into the expandable elastic reservoir where it is then discharged through the nozzle.
