Shutter assembly using a resilient material

摘要

There is disclosed a shutter assembly including: (a) a surface defining a surface opening; (b) a housing associated with the surface which defines a passageway in communication with the surface opening, wherein the housing surface defining the passageway includes a housing hole; and (c) a resilient material defining an end surface, which is disposed in the passageway and covers the housing hole, wherein the size of the end surface permits the application of an external force against the end surface to compress the resilient material to uncover the housing hole, and whereby the resilient material spontaneously expands to cover the housing hole when the external force ends.
