Title:
LEAK PROOF COLLAPSIBLE CUP
Document Type and Number:
WIPO Patent Application WO/2012/107861
Kind Code:
A2
Abstract:
Provided are collapsible compact cups and sealing cup lids for everyday use. The cups are designed with two or more rigid portions that are used to engage with the cup lids and support the cup. The rigid portions are interconnected by one or more flexible middle portions configured to support the upper rigid portion when the cup is in the upper operational position. At the same time, the flexible portion may bend under a certain force exerted by the user during collapsing of the cup and may allow one rigid portion to slide over another rigid portion. Even in this lower collapsed position, all rigid and flexible portions of the cup may remain connected to each other, thereby preventing any spills from the cups (e.g., residual liquids) creating a pocket sized cup with a sealing lid.
