Abstract: A cover device may include a body with an inner surface and an outer surface, each of the inner surface and the outer surface extending from a first end face of the body to a second end face of the body. The inner surface may define a channel extending through the body from the first end face to the second end face. The body may define a plurality of grooves extending from the first end face to the second end face. Portions of each groove may be defined by the inner surface, the first end face, the outer surface, and the second end face. Each of the body, the inner surface, and the outer surface may be configured to elastically deform relative to at least an axis of the channel.

Abstract: A straw for sipping a liquid that includes a tube, a base that depends from the tube, and protrusions that depend from the base. The base has a primary throughbore that is in fluid communication with the tube and allows the liquid that is below the base to be drawn up therethrough and up through the tube so as to provide a main flow. The base further has at least one secondary throughbore that is independent of both the primary throughbore and the tube and allows the liquid that is above the base to be drawn down therethrough and up through the primary throughbore and up through the tube so as to provide a flow that supplements the main f low. The protrusions are cylindrically-shaped and formed, and separated from each other, by fine grooves that are approximately {fraction (1/64)}″ wide so as to allow the base to crush and mix sugar granules in the liquid.
