ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the invention
The invention pertains generally to devices for dispensing fluids such as liquids or loose materials. In particular, the invention relates to a device for dispensing measured quantities of a fluid from a container that forms a metering container when using such a device.
2. Description of the related art
Devices for dispensing measured quantities of a fluid from a bottle and metering bottles are well known in the art. Donoghue, U.S Pat. No. 3,581,953, discloses a refillable and flexible walled container that has first and second integrally formed chambers arranged one above the other, with an integrally formed separating wall therebetween. A tubular plug is threadably received in an insert fixed in an opening defined by said separating wall, and access to the plug is provided through a dispensing opening in the upper or second chamber. The plug carries a tube or conduit, through which liquid can be forced by squeezing the lower or first chamber-defining portion. Also, the plug has a laterally open passageway for directing the liquid toward the side of the second chamber to permit filling of the latter to a desired level, after which the container can be inverted to dispense only that liquid in said second chamber.
Zipper, U.S. Pat. No. 3,796,348, describes liquid metering and counting and dispensing means where a liquid pourer is attached to a bottle for automatically dispensing a predetermined amount of liquor each time the bottle is tilted to pouring position. The number of such tilts or dispensing operations appears as a count. The count is read from a sleeve, which is advanced one count. Such sleeve has saw-toothed type projections at each of its ends cooperating with complementary projections to assure advancement of the sleeve only one count for each dispensing operation. The amount of liquor dispensed is metered using a plunger assembly having apertured portions therethrough, which are covered by a valve element movable on the plunger assembly. The position of the plunger assembly is adjustable to adjust the amount of liquor dispensed. To prevent dispensing of liquor unless the bottle is in substantially an upright, inverted position, a so-called antimilking device is associated with the pouring spout. It involves a spool-shaped valve element carrying a locking ring, which is engageable with an abutment on the pouring cap to prevent this valve element from uncovering openings in the pouring spout unless the bottle is in substantially a completely inverted position. Thus, complete advancement of the counting sleeve prior to dispensing of liquor is assured.
Guala, U.S. Pat. No. 3,894,661, discloses a liquid measuring and dispensing bottle closure device for attachment to the neck of a bottle. It is formed as a cylindrical hollow body with a metering control chamber located concentrically in the chamber and a central air inlet tube which projects into the metering control chamber. When the pourer is attached to a bottle, the central air inlet tube communicates with the interior of the bottle, where a transverse diaphragm having a plurality of openings is provided. Through those openings, the liquid must flow to pass from the bottle. The openings are sufficiently small to be spanned by a film of the liquid due to surface tension, once wetted thereby, so as to prevent the inflow of air to the bottle by the liquid exit route. In this way, the airflow into the bottle only via the air inlet tube is controlled.
Donoghue, U.S. Pat. No. 4,077,547, discloses a measuring and dispensing apparatus for use with a flexible-wall container. The apparatus is a combination of a dispensing means, wall means and a tube. The dispensing means has an enlarged cylindrical base portion with container engaging means thereon and an upstanding portion. The upstanding portion has an upper end and a lower end, the lower end being disposed on the enlarged base portion. The upstanding portion also has a bore and an outlet orifice disposed proximate the upper end and in fluid communication with the bore. The wall means is disposed around the dispensing means and forms, with the enlarged base portion a fluid measuring chamber. The chamber has an upper end having a fluid outlet. The tube has an inlet end and an outlet end, and is arranged so that the outlet end is disposed in the bore in the upstanding portion of the dispensing means and in fluid communication therewith, whereas the inlet end is adapted to be disposed in the flexible-wall container.
Morris, Jr., U.S. Pat. No. 4,105,142, discloses a device for dispensing fluid substances. The device includes a dispensing container for holding a metered amount of the fluid substance in it immediately prior to dispensing, a hollow adapter and a valving system within the adapter. The dispensing container includes a primary opening in its top edge, which is adapted to be capped during filling of the dispensing container and which is adapted to be opened when it is desired that the metered amount of fluid substance be dispensed from the container. The dispensing container also includes a secondary opening in its lower section, which may be substantially smaller than the primary opening. The hollow adapter is secured to the secondary opening of the dispensing container and adapted to be secured to the neck of a bottle or other source of the fluid substance to be dispensed. The hollow adapter includes a dispensing collar adapted to be secured to the secondary opening of the dispensing container and a holder collar adapted to be secured to the neck of a bottle or holder of the fluid substance. Also, the hollow adapter includes a collapsible and expandable sleeve, which is hollow and interconnects the two caps of the adapter to provide a path of fluid flow communication between the holder of the fluid substance and the interior of the dispensing container. The valving system within the adapter meters the amount of fluid substance flowing into the dispensing container. The valving system may include a rubber plug member adapted to be placed within the secondary opening of the dispensing container to prevent fluid flow communication through this opening, The positioning of the plug within the secondary opening is responsive to the expanding or collapsing of the sleeve of the adapter.
Donoghue, U.S. Pat. No. 4,106,673, describes a liquid measuring and dispensing apparatus that represents the combination of a reservoir container having a flexible wall and measuring and dispensing means disposed on the reservoir container. The measuring and dispensing means comprises an outer wall member and an inner wall member. The inner wall member is disposed within the outer wall member and spaced therefrom to define liquid passage means between the outer wall member and the inner wall member. The inner wall member defines a measuring chamber within the outer wall member. Liquid passage means are provided in liquid communication with the liquid passage and the measuring chamber, and conduit means are disposed in the reservoir container and in liquid communication with the liquid passage means.
Coetzee, U.S. Pat. No. 4,180,106, presents a dispensing and metering device, which can be attached to the neck of a bottle. The device has a housing defining a chamber having an inlet and an outlet. The chamber can be filled through the inlet with liquid from a bottle secured to the device by an attachment element and can be drained through the outlet. A valve arrangement includes an outlet nozzle extending generally away from the outlet. The arrangement is movable from a first condition, in which it closes the inlet and opens the outlet, through a second condition, in which it closes both the inlet and the outlet, to a third condition, in which it closes the outlet and opens the inlet. A flow path is defined at least partly within the valve arrangement for introducing air into the chamber via the nozzle and the outlet. The air replaces liquid flowing from the outlet when the outlet is open. The valve arrangement is resiliently biased to th
