Abstract: An improved water gun toy or like device having a cylindrical body substantially closed at one end thereof to form a body chamber, a piston of cylindrical shape slidably and sealably positioned within said body chamber for axial movement therein, the piston and the body including the closed end thereof defining a liquid receiving reservoir of substantial capacity. The piston is slidable from one axial end of the body chamber to the other axial end thereof. A conduit in fluid communication at one end with the reservoir and having an outlet orifice on the opposite downstream end thereof from which liquid can be ejected and manual actuating device operatively connected to the piston and operable to cause axial movement of the piston from one axial end of the chamber to the other axial end thereof is provided whereby substantially all of the liquid in said reservoir may be ejected through the orifice in a continuous stream.

Abstract: In a manually operated dispenser especially suited for striped toothpaste products and the like the reciprocable pumping piston is provided with a concave, product-engaging face that gently, yet forcibly, directs the product in a smooth, laminar flow out of the pump chamber and into the discharge spout when the piston is depressed through a pumping stroke so that stripes in the ribbon of toothpaste issuing from the spout are well defined and maintained in an aesthetically pleasing manner. The cooperating floating takeup piston at the opposite end of the chamber from the pumping piston is provided with a convex dome that becomes complementally received within the concavity of the pumping piston when the contents of the dispenser are nearly depleted, thereby maximizing the degree to which the dispenser is emptied.

Abstract: A seeding device to dispense seed suspended in a gel or other carrier medium in either a continuous stream or discrete pulses. A coulter opens a furrow of earth to the proper depth and seed carried in a gel or other suspension medium is delivered in a pulsed or continuous stream into the furrow which is then covered with earth by a trailing coverer. An auger delivers the seed in suspension and the speed of the auger is controlled to vary the volume of seed and gel or other suspension medium delivered. Circumferentially spaced cam lobes on a drive wheel control the frequency and therefore the row spacing of the seed suspension medium distributed in the pulse delivery mode.

Abstract: Serrations on the upper end of the pump body are disposed for interlocking engagement with depending portions of the pump collar so that when the plunger is rotated in a counterclockwise direction to unlock the same from the collar in preparation for reciprocal operation, the collar is held securely by the body against rotation to assure unlocking. The serrations take the form of a plurality of equally circumferentially spaced ramps which are inclined in the direction of locking rotation of the plunger to thereby permit the collar to yieldably override the serrations when the locked plunger and collar are rotated as a unit in the locking direction relative to the body to orient a spout of the plunger in a desired location for factory packaging efficiency.

Abstract: A dispenser for paste-like products comprising a preferably cylindrical container for the product to be dispensed is provided with delivery device in the form of a delivery piston (6), the surface area of which is substantially equal to the interior cross-sectional area of the container (7). Connected to this piston is a dispensing structure (2) including a valve (4). The delivery piston is disposed within the upper end portion of the container and is designed for manual operation.

Abstract: A dispensing container having a sloped bottom wall, into a lowermost portion of which, a feed tube is extended and connects to a dispensing spout on a top of the container, and the feed tube in one design thereof including a conical fitting in a flared lower end thereof for controlling flow therethrough, and in another design the tube including a floatation member to sufficiently lift the tube lower end off the bottom wall so to allow entry of dispensing material thereinto.

Abstract: In a dispensing device for filling boreholes with a single or multi-component adhesive, filler, sealer or primer, the material is conveyed from storage containers holding the individual components through a supply pipe and an outlet nozzle which dispenses the material directly into the borehole. By manually operating a handle lever, material is displaced out of the storage container into the supply pipe. Further, an actuating unit operated by the handle lever is connected to the outlet nozzle for telescoping it relative to the supply pipe whereby material is displaced out of the supply pipe through the outlet nozzle into the borehole.

Abstract: A container for holding a viscous liquid medium and from which the same may be selectively dispensed in a desired amount includes a rigid body having a deformable top portion and carrying a dispensing mouthpiece. The application of an inwardly-directed force to the mouthpiece deforms the container top portion and causes displacement of the mouthpiece partially into the container interior such that valve openings in the mouthpiece that are normally disposed sealingly within a valve body in the interior of the container are carried to a position remote from and clear of the valve body to clear the valve openings and permit a dispensing flow of liquid through the mouthpiece and thereby out of the container body.

Abstract: A liquid-dispensing pump arrangement permits positive setting into various full-stroke, stroke limited, and off positions by rotation of the dispensing head thereof. The arrangement includes a reciprocating pump having a dip tube, a pump body, and a depressible stem and which is supported in a screw cap or other closure. A pedestal on the screw cap has longitudinal detents on a circumferential surface thereof, and also has a helical ramp thereon extending at least part way around the stem. A finger-depressible push-button dispensing head atop the stem has a radial outlet nozzle and a depending skirt which overlaps the circumferential surface of the pedestal. Fins or vanes on the skirt are spaced apart and engage the detents on the pedestal. The vanes are resiliently flexible and normally engage the cutout detents to establish each rotational position, but can be deflected by manually turning the dispenser head so that the latter can be easily rotated to another desired position.

Abstract: A controllable volume dosing device for providing a measured dose of material. The volume dosing device comprises a cylinder having a piston movably mounted therein for movement between a first end position and a second end position, and drive device for moving the piston between the two end positions. A valve is provided associated with the cylinder and which is positionable in a first valve position in which material may be introduced into the cylinder and a second valve position in which material may be expelled from the cylinder. The displacement of the piston within the cylinder between the first and second end positions controls the volume of the dose of such material. An adjustable stop member associated with the piston is provided for defining the first end position of the piston.

Abstract: A dispensing device for applying a pasty substance, for example to a human hair, comprises a cup-shaped cylindrical container and a piston located therein and displaceable within the container. The container is sealingly connected to an operating extension having a cylindrical passage terminated with a dispensing nozzle which is selectively closed by a sealing cap. The piston is formed with two sealing lips spaced from one another in the axial direction and outwardly and angularly extending from the periphery of the piston so that one of the lips sealingly connects the piston to the internal wall of the container whereby the second lip is adapted to reliably guide said piston within the container.

Abstract: A container for fluid products having telescoping parts and operable by outside manual pressure is provided. The container assembly includes a base cup, a plunger cup telescopingly received in the base cup and relatively slidable therein, a nozzle in direct communication with each of the cups, and a pair of slidable pistons, one located in the base cup and relatively fixed with respect to the plunger cup and the other located in the plunger cup relatively fixed with respect to the base cup, for forcing product from the cups to the nozzle upon telescoping movement of the cups together. An air intake is provided to admit air from the surrounding atmosphere between the cups into an interior space adajcent to the slidable pistons to avoid a vacuum in the container and prevent seepage of the products from the cups. A set of locking threads is formed on each of the cups for locking the cups in an extended relationship to prevent undesired telescoping movement in the filling and handling of the container.

Abstract: A container for fluid products having telescoping parts and operable by outside manual pressure is provided. A base cup open at the top receives a plunger cup that is slidable therein with product being filled in both cups. A slidable piston in the plunger cup dispenses product from the plunger cup concurrently with the dispensing of the same or different product by the plunger from the base cup. A dispensing nozzle is provided in one of the cups with a transfer tube connecting the nozzle to the other cup. The container assembly includes four injection molded plastic parts, namely, (1) the base cup, (2) the plunger cup, (3) the piston and (4) the cap and nozzle assembly; these parts snapping together during the combined filling and assembling process. Integral snap rings and snap beads are used to lock the parts together. Once assembled, the piston locks the plunger cup against either in or out telescoping movement to prevent accidental dispensing during shipping and handling.
