AI Technical Summary

Problems solved by technology

Even with the ability to be disassembled for cleaning, some known valves and valve assemblies are prone to soiling
Certain valves and valve assemblies are difficult to disassemble and reassemble because they require precise alignment or orientation
Also, if the cup is disassembled, the small valve or parts of the valve assembly could easily get lost or be a hazard to children

Embodiment Construction

[0047] Referring now to the attached drawings, in particular to the figure 1 and figure 2, a leak-proof drinking cup, generally designated 1 , includes a container, generally designated 3 , and a lid assembly, generally designated 9 . The illustrated container 3 is generally cylindrical and symmetrical about a central axis. The container 3 has a closed bottom 5, an open top 7, and a generally cylindrical side wall 6 extending between the closed bottom and the open top. The cylindrical side wall 6 includes a base portion 8, a top portion 10, and a concave middle portion 12 extending between the base and top portions. The middle portion 12 of the side wall 6 of the illustrated container 3 is concave to facilitate gripping the container and thus the cup 1 . It should be understood, however, that the intermediate portion 12 may be convex or generally straight. The base portion 8 of the side wall 6 includes a plurality of circumferentially spaced protrusions 14 . The top port...

Abstract

A leak resistant drinking cup has a container with an open top and a lid assembly for removable attachment to the container for selectively closing the open top. The lid assembly includes a liquid discharge member for allowing liquid in the container to exit the cup. A closure member is adapted for placement adjacent the open top of the container when the lid assembly is attached to the container. A flexible diaphragm is moveable from a sealed position to unsealed position by a vacuum being applied to the diaphragm by a user sucking on the liquid discharge member. The vacuum causes the diaphragm to flex toward the container and at least in part away from the closure member and thereby move the diaphragm from the sealed position to the unsealed position. The liquid discharge member and sealing member may be formed as one-piece.

Description

technical field [0001] The present invention relates generally to leak-proof drinking cups, and more particularly, to leak-proof drinking cups having a septum movable between a sealed position and a non-sealed position. Background technique [0002] Spill-proof drinking cups are generally suitable for use by young children (eg, infants, toddlers, preschoolers). These types of drinking cups are constructed such that when they are inverted, the liquid in the cup is prevented from spilling out of the cup by a valve or valve assembly. Typically, a cup comprises a container having an open top for receiving and retaining liquid therein and a relatively rigid cover for closing the open top of the container. The spout is usually made in one piece with the rigid closure to allow the child to drink from the cup. The closure may be releasably attached (eg snapped or screwed on) to the container. [0003] A valve or valve assembly is typically disposed between the lid and the contain...
