FEEDING CUP Russian patent published in 2010 - IPC A61J9/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine and food processing industry. A feeding cup adapted to integration with a feeding container comprises a mouthpiece with a spring-loaded valve to overlap a consumption manifold tube. A mouthpiece body represents an open bottom cylinder cup 1. The valve is a piston 2 movable in the body. In its front end on top, the cup has a transverse truncated V-notch 3 formed by three planes, one of which is perpendicular to a longitudinal axis of the cup 1, the other is inclined to this axis with forming a chamfer directed to the mouthpiece end, and the third is parallel to the axis. In its front part below, the piston has longitudinal flat forming an outlet 4; besides it comprises a long guide slot 5, and in the cup 1, there is a pin 6 that inhibits the rotation and fall-out of the piston 2 from the cup 1. In its back part below, the cup 1 has an external longitudinal flat used as a passage way 7 to supply the contents from a feed tube 9 to the outlet 4 of the piston 2. At the bottom, the cup 1 has a lock spring 8 which pushes the piston 2 forward and separates the passage way 7 and the outlet 4 of the mouthpiece. The same as the cup 1, the piston in its front end on top has a transverse truncated V-notch 10 also formed by three planes, one of which is perpendicular to the longitudinal axis of the piston 2, the other has a reverse inclination to this axis in comparison with the notch 3 in the cup 1, also forming a chamfer, but directed to the start piece of the mouthpiece, and the third one is parallel to this axis. The notches in the cup 1 and the piston 2 are matched, and their opposed chamfers are crossed.

EFFECT: invention provides cleanness and availability of a beverage when using the feeding cup with the use of fewer details in comparison with an analogue; the offered device can be applied for carbonated beverages as well.
