Abstract: A sealing lid is disclosed that includes a flexible annular closure membrane surrounded by a heavier annular rim member that is preferably adapted to hold the lid in place on a container to define a first position. The closure membrane can be axially flexed from the first position to a second position using a single hand. In the second position, the membrane axially depresses to lower down the pressure in the container and forms a hermetic vacuum seal with the container. The heavier rim member has a weight that is substantially greater than the weight of the membrane that is adapted to press down the lid over the container. The heavier rim member supports hermetic sealing by facilitating intimate contact between the lid and the container.

Abstract: A measuring device is disclosed that includes a plurality of measuring cups connected through a ring. Each measuring cup has a lobed sidewall defining a plurality of lobes of an epicycloidal configuration. Each lobe of smaller cup contacts an inner surface of the sidewall of the larger cup to define a void between the cups that facilitates air to flow between the cups. The flow of air prevents suction between the cups. The epicycloidal configuration defines a plurality of longitudinally raised portions that are adapted to stop an axial inward movement of the next smaller cup and hold next smaller cup in position. The epicycloidal configuration of the sidewall defines a plurality of channels that form a plurality of spouts within the container portion to permit drip-free pouring. The channels facilitate minimum inter-surface contact between the cups to prevent sticking of their surfaces.
