Abstract: A single dose dispensing closure has a main body with an upper skirt portion for measuring and dispensing a predetermined dose of a flowable product from a container. A bottom wall, a rearwardly angled wall extending upwardly from the bottom wall, and an interior surface of the upper skirt together define a measuring reservoir. A port allows a product to flow from a container into the main body. A lid is movable to a closed position in which the lid portion and the main body define a filling chamber. A hinged closure tab seals an exit orifice on the front of the lid portion. When the exit orifice is closed, a user inverts the dispensing closure and container to substantially fill the filling chamber. When the dispensing closure is righted, a predetermined dose of the flowable product is retained in the reservoir, ready to be dispensed through the exit orifice.

Abstract: The invention relates to a device (1) for metering media (2) and comprises at least one storage vessel (3), a measuring vessel (14) and a target vessel (14) that are interconnected to give one unit. By the exertion of force on the media (2) to be metered they can communicate between the storage vessel (3) and the measuring vessel (4) and can then be transferred to the target vessel (14). The metering volume is determined by the geometry of the measuring vessel (4). The target vessel (14) can be separated from the measuring vessel (4) by severing (welding, gluing, cutting) the connection between (14) and (4). The invention also relates to a method for metering media using the device (1) according to the invention. The device is suitable as a disposable unit and for the sterile metering of media in a non-sterile environment.

Abstract: A fluid dispensing device comprises a tube and a holding means. When used with a container, the holding means is connected to a neck of the container and the tube is plunged into an interior of the container. An area on the tube, by which the tube is held by the holding means, defines a distance between a lower end of the tube and the bottom of the container. Consequently, a maximal amount of the fluid for the selected area that can be dispensed from the container upon its tilting is determined. A metering container is formed by combining the dispensing device and a container.

Abstract: A container that can dispense a small amount of the contents has a body (10), a dispenser (20), a tube (30) and a cover (40). A baffle (24) is integrally formed in the dispenser (20) to close the opening between two ends of the dispenser (20). A tubular protrusion (25) integrally protrudes from the baffle (24) to form a passage between the two ends of dispenser (20). The tube (30) is adjustably inserted into the tubular protrusion (25) to define a first passage between the tube (25) and the cover (40). The cover (40) has an outlet (43) defined in the cover (40). A wall (42) extends downward from the cover (40) to define a U-shaped second passage between the first passage with the outlet (43). Consequently, a small amount of the contents can be poured out of the container, and the dispensed quantity of the contents is adjustable.

Abstract: A method and device are disclosed for metering a predetermined amount of a particulate substance in a reliable and exact manner. The claimed invention avoids crushing or packing the material to be metered, and can be utilized with fine particulate substances with poor flow properties such as agglomerates as well as with coarser granulates. The substance to be metered is gravity-fed by a tumbling reservoir and inlet through an unbroken and uninterrupted inflow path which comprises two parts, one which is coaxial with the rotational axis, and a second which is inclined relative to the rotational axis. After passage through the inflow path, the substance enters the metering chamber which accurately and uniformly measures the desired quantity of substance, which then exits through the outflow path. The design of the device prevents inaccurate metering through overfilling or premature emptying of the metering chamber.

The device can measure and dispense a variable amount of material by changing the volume of a variable volume chamber. The device can also be automated to turn by an electric motor or a mechanical device operated by a hand squeezed trigger. The device can be a hand-held tube for dispensing free flowing materials, or it can mount on the top of a container of free flowing materials, and be used to dispense quantities of the free flowing material on demand.

Abstract: By the side of a powdery or granular material stacked in a conical pile on a horizontal surface, a sensor that emits sensor light and, by receiving light reflected from a spot illuminated by the sensor light, detects the distance to the pile of the powdery or granular material is placed with the optical axis of the sensor light horizontal. While the sensor is moved in a horizontal direction perpendicular to the optical axis of the sensor light, the distance to each of a plurality of measurement points arranged horizontally at regular intervals along a line that runs on said pile of the powdery or granular material so as to face the movement path of the sensor. This step is performed every time the sensor is moved vertically a predetermined distance at a time. In each session of the step, a point is extracted that is closest to the sensor, and a function describing a straight line approximating the curve through all of the thus extracted points is determined by the least-squares method.

Abstract: Apparatus for dispensing a measured amount of liquid from a container is adjustable for allowing different measured amounts of liquid to be dispensed from the same container. The apparatus is adaptable for use in the context of two-compartment, squeeze-type containers and two-compartment, inversion-type containers. The latter is a new type of container that allows a measured amount of liquid to be transferred from a storage compartment to a dispensing compartment without the need for an air vent to the outside of the container. The apparatus is designed so that additional liquid from the storage compartment is prevented from entering the dispensing compartment during dispensing of a measured amount of liquid from the container.

Abstract: A dispensing device for dispensing measured doses during each dispensing cycle. A fluid tight bottle is provided with a well at its bottom. A hollow shell fits in the well and includes an opening permitting flow of material from the bottle into the shell. A tubular stem extends from the shell through the top of the bottle and terminates in a dispensing spout. Different embodiments provide different arrangements for supplying air to an air chamber in the top of the bottle so that pressure within the bottle can equalize at the end of each dispensing cycle. If the bottle is not a squeeze bottle, air is supplied to the bottom of the bottle to displace the liquid in the shell which is dispensed through the stem upon inversion of the bottle. Additional embodiments of the invention are specially constructed to dispense powders and to allow the dosage of each dispensing cycle to be adjusted.

Abstract: Technique and apparatus for measuring liquids and granular material comprises a combination including a measuring vessel attached adjacent to the top and communicating with the primary container through the modifying pour spout of the latter. The measuring vessel includes an outwardly directed dispensing mouth having a removable closure, and a second upwardly directed opening vertically aligned with the pour spout of the primary vessel. In a preferred embodiment, the modifying pour spout of the primary container serves as a handle for the combination. After the primary container is filled through a tube extended through the second opening of the measuring vessel, this opening is either sealed, or a manually-operable valve is interposed into the opening. The manually-operable valve may alternatively take the form of a flap valve, or a piston valve, either of which operates to open and close communication through the modifying pour spout between the measuring vessel and the primary container.

Abstract: A fixed volume discharge device adapted to be mounted to a container, and having a first chamber communicating with the interior of the container and a second chamber communicating with the atmosphere, the first chamber and the second chamber communicating with each other through a restricted opening. A liquid or powder stored in the container flows into the first chamber when the container is downwardly inclined, and then flows into the second chamber from the first chamber when the container is returned in its normal attitude. Thus, when the container is again downwardly inclined, the liquid or the powder within the second chamber is discharged while the liquid or the powder in the container flows into the first chamber, thereby a predetermined fixed volume liquid or powder is obtainable through the fixed volume discharge device each time the container is downwardly inclined.
