Abstract: Provided are a collapsible cup and a lid for sealing such cups. A collapsible cup includes a top cylindrical portion having a collapsible part and a sealing edge. The cup also includes a rigid bottom portion attached to the collapsible part and configured to move in and out with respect to the sealing edge by folding the collapsible part. The level of folding of the collapsible part determines different positions of the top portion, such as upper operating position corresponding to the maximum cup height, an intermediate operating position corresponding to an intermediate cup height, and a lower collapsed position corresponding to the minimum cup height. In the lower collapse position, the bottom portion may be substantially enclosed by the top cylindrical portion. The collapsible cup may include a reinforcement insert disposed within the top portion and used for engaging with a lid and providing support to the sealing edge.

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.
