Abstract: A consumer product or toy suction cup ensemble includes a housing, a suction cup formation, and a relief valve formation. A collar element may be included in certain embodiments. The housing includes a stem-letting aperture. The suction cup formation includes a collapsible cup portion and a stem portion. The stem portion includes a valve-letting passage. The stem-letting aperture receives the stem section. The relief valve formation includes a valve stem and a valve upper portion. The valve stem includes opposed valve stem grooves that extend from a valve stem end and have a groove length lesser than the valve stem thereby forming a valve-sealing portion. The valve stem is receivable in the valve-letting passage. The collar element of certain embodiments includes an outer collar periphery and an inner slot portion. The inner slot portion accepts the collar-receiving stem section and the outer collar periphery is wider than stem-letting aperture.
