    Abstract: The invention relates to a method for filling and evacuating a dispenser unit for paste-like, foam-form or liquid media. In the known methods, a storage container is evacuated via a suction pump, which otherwise serves for the delivery of the medium, after filling. The risk exists hereby that medium is drawn in. In order to make the drawing-off process more effective and more reliable, a method and a filling insert for a dispenser unit are proposed according to the invention, wherein at least one air duct is provided parallel to the suction pump. The evacuation takes place by the application of a pressure difference between storage container and the environment, which is just so great that air can in fact be drawn through the air duct but no viscous medium can be drawn.

  • Publication number: 20130189404
    Abstract: The invention proposes an improved method and system for carrying a solvent. To this end, the system (10) for carrying a solvent (20) according to the invention comprises: a container (30) for containing said solvent, a tube (40) placed in said container, said tube having a first extremity (41) placed in the proximity of a bottom part (36) of said container, and a second extremity (42) extending up to an upper part of said container, and an air pump (50) for generating an air flow exiting at said bottom part, such that at least part of said air flow can enter the tube at said first extremity, for carrying said solvent in said tube from said first extremity to said second extremity. By generating an air flow by means of an air pump instead of vapor bubbles naturally generated by locally boiling solvent, solvent can reach the second extremity of the tube while having a much lower temperature than the boiling temperature of the solvent.

  • Publication number: 20130168420
    Abstract: The present invention is a fuel transfer pump for use with standard portable containers of various sizes, shapes, manufacturers and configurations. The fuel transfer pump allows the user to fuel objects higher or lower than the portable container, quickly, without the need to lift the portable container. The core components of the invention are a wheeled framework (cart), clear flexible tubing, fill handle/nozzle (shut-off valve), double-action air pump with hose, and connector sleeve, which, generally speaking, are configured as follows: the connector sleeve attaches and seals the portable container outlet to the tubing, which extends down to the bottom of the container on one end and has the fill handle/nozzle (shut-off valve) at the other end; the sleeve also has a port to attach and seal to the air pump hose to enable pressurizing the container, inducing fuel flow.

  • Publication number: 20130043283
    Abstract: A foam pump has a spring isolated from a flow path. Due to the arrangement of inner tube and outer tube of the pressing head and a spring installed between the inner tube and the outer tube, in the suction process, the liquid (or emulation) in the bottle flows through the inner channel of the inner tube and thus it does not contact with the outer tube so that the foams will not be polluted by the material spring. The spring is isolated with the foaming flow path so that it does not resist the flow of the foams; the liquid (or emulsion) does not contact the foams so that the foams are not polluted and thus the liquid in a bottle is retained purely; the liquid is not chemically reacted with the material of the spring and thus no harmful object generates.

  • Publication number: 20120318829
    Abstract: This invention disclosed herein relates to a pump apparatus for use with a liquid container for transferring liquid from a liquid container. It comprises a pump means comprising a manually-operable pump for pumping liquid and formed with a pump chamber through which liquid can be pumped by the pump. It also has an inlet opening for receiving liquid into the pump chamber and an outlet opening for dispensing liquid out of the pump chamber when liquid is pumped through the chamber using the pump. There is a coupling means for mounting the pump means to the opening of a liquid container to permit the gravitational flow of liquid into the pump chamber through the inlet opening when the mounted pump means is placed on ground level and the pump pumped.

  • Patent number: 8313010
    Abstract: A bifurcated foam pump assembly for use in foam dispensers. A liquid dispensing portion of the foam pump assembly is attached to and disposable/replaceable with a liquid cartridge for the dispenser. The air compressor or air pump portion of the foam pump assembly comprises a portion of the dispenser itself and is attached to the dispenser housing. Upon replacement of a cartridge, the two portions mate and are operative as a foam pump generator. The liquid portion of the foam pump is received within a liquid chamber by gravity, and is subsequently driven from that chamber by air from the air compressor, which drives both the air and liquid through a foam generating member, such as a sponge or mesh. This foam generating member is a part of the liquid portion of the pump, and is replaced with the cartridge.

  • Patent number: 8297480
    Abstract: An air-pump type discharger capable of discharging a dose of contents, such as toothpaste, using pneumatic pressure and a dispenser for daily necessaries including the same are disclosed. The air-pump type discharger includes a housing inserted in a dispenser body, and provided with a plurality of air vent holes around a piston receiving portion formed on a bottom surface of the housing; a piston having a pushing part with an opened lower portion and inserted in an upper opening of the housing, and a connector extending from a bottom surface of the pushing part, inserted in the piston receiving portion, and contacting the bottom surface of the housing, in which an air passage is formed in the pushing part and the connector, through which air passes; and a spring, installed within the housing, for resiliently supporting the piston upwards. Since the discharger is easily detached from the dispenser body, the assembling workability and the recycle of resources can be improved.

  • Patent number: 8172929
    Abstract: Various embodiments of the present invention are directed to limiting a presence of air bubbles in fluidic media in a reservoir. Air passages may allow air to escape from fluidic media in a reservoir. Membranes may allow for trapping air bubbles in fluidic media before fluidic media enters a reservoir. A membrane may allow air to flow from a first reservoir containing fluidic media to a second reservoir while plunger heads within each of the reservoirs are moved within the reservoirs. An inner reservoir with a membrane may be moveable within an outer reservoir to allow air to move from the outer reservoir to the inner reservoir. An inner reservoir containing pressurized gas may allow fluidic media to be transferred to an outer reservoir.

  • Patent number: 8172115
    Abstract: A dispenser for hair building solids can be readily operated and aimed with one hand. A bulb that provides air for suspending the solids is located directly on top of a dispenser body. The bulb can be depressed by a single finger when the device is held in one hand. When the compressed air exits the bulb, it follows a direct straight downward pathway to the surface of the hair building solids. Air exiting the bulb passes through an air injecting orifice that is directed towards the surface of a mass of hair building solids suspending the solids within the turbulently pressurized container, which solids are then directed smoothly by the domed undersurface of the dispenser body into the straight bore of a short nozzle. The path followed by the solids is without bends thereby avoiding clogging.
