Patent number: 4924922Abstract: A heat insulated coffee carafe for placement at the brewed coffee outlet of a coffee maker is provided with a securely fitting lid through which the coffee passes directly into the carafe without removal of the lid. When the carafe and its lid are placed in the coffee maker, mutual pressure between the lid and the coffee maker causes seals in the lid to open and permits the coffee to enter the carafe without removing the lid and with a minimal loss of heat and coffee aroma. Removal of the carafe and lid from the coffee maker automatically closes the seals to retain the heat and aroma in the carafe for long periods of use. In another embodiment a positive drip-stop seal in the coffee maker is closed automatically when the carafe is removed, whereby dripping from the coffee maker is prevented. In a further embodiment, a drip-stop seal in the coffee maker and a seal in the lid are both opened when the carafe is installed in the coffee maker.Type: GrantFiled: October 17, 1988Date of Patent: May 15, 1990Assignee: Black & Decker, Inc.Inventor: Paul D.

Patent number: 4909289Abstract: A valve (20) has a valve housing (22) with a central passage (28) extending axially through the valve housing (22). Aperture (40) in the valve housing connect a second passage (38) to the central passage (28) to extend through the valve housing. A poppet valve member (24) is configured for sealing engagement of the central passage (28). The valve member (24) is urged into sealing engagement with the central passage (28) by internal pressure in a container (36) on which the valve (20) is provided. The valve member (24) and the valve housing (22) are configured so that the valve member (24) will drop away from sealing the central passage (28) when the pressure in the container (36) is insufficient to hold the valve member (24) in sealing position against the central passage (28) to leave the valve (20) in a permanently open state. An annular valve member (26) seals the second passage (38 ) in the same manner.Type: GrantFiled: July 2, 1987Date of Patent: March 20, 1990Assignee: Jopado BaderiInventors: Richard J.

Patent number: 4877160Abstract: A valve unit to be used in a packing machine of the type which manufactures filled and sealed non-returnable packages for dairy products such as milk, yogurt and the like from prefabricated blanks. The packages are filled one at a time by a metering pump and the liquid is fed from the pump to the package via the valve unit. The valve unit includes a check valve and a flexible nozzle which co-operate so as to prevent any after-dripping between pumping strokes. This is achieved in that the check valve with the help of a piston component, after the completed pumping stroke, creates a vacuum in the liquid filled valve unit. This vacuum affects the flexible nozzle so that it closes rapidly and effectively.Type: GrantFiled: March 29, 1989Date of Patent: October 31, 1989Assignee: Tetra Pak International ABInventor: Jackie Derving

Patent number: 4834151Abstract: A fluid conduit attached at one end to a container of fluid is provided at the other end with a fluid discharge opening through which fluid can be transferred into a receiving vessel. A slide valve on the exterior of the conduit is biased into a closed position, precluding any fluid flow from the conduit until the discharge opening is inside the receiving vessel. The slide valve coacts with the receiving vessel to open and permit fluid flow. An air vent tube within the conduit communicates with an air vent opening in the vicinity of the discharge opening. The air vent tube includes one or more capillary sections of reduced inner diameter relative that of the air vent tube. The air bent tube admits air into the container to facilitate fluid flow, while the capillary section limits the rate at which the air enters, thereby reducing the pressure of air in the container below ambient pressure when fluid flows from the conduit.Type: GrantFiled: March 16, 1987Date of Patent: May 30, 1989Assignee: VEMCOInventor: Verl Law
