Abstract
Abstract A suction cup is configured to assure a permanent attachment of an instrutation package to a surface. A dish shaped body member is provided with an annular lip which resiliently engages this surface. A radially outwardly disposed ring shaped recess contains a highly resilient material, such as gum rubber or adhesive liquid. This material is extruded out of the recess as the annular lip is pressed against the surface to ensure a long term, permanent attachment.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
194 words
An apparatus for attaching an object to a surface comprising: means coupled to the object and defining a cavity for resiliently creating a suction, the creating means is provided with an annular portion resiliently engaging the surface after the cavity has been compressed, the resiliently creating means includes a molded dish shaped shell of a resilient material and the annular portion increases its area of resilient engagement on the surface as the cavity is being compressed; means mounted radially outwardly from the annular portion for defining a ring shaped recess configured to be reduced in size upon the compression of the cavity, the ring shaped recess having a first portion and a second portion integrally formed with the resiliently creating means, the second portion is disposed radially outwardly of the first portion, said first portion moves radially outwardly toward said second portion as the cavity is compressed to compress the ring shaped recess; and means disposed in the ring shaped recess and being extruded therefrom as the cavity and the ring shaped recess are being compressed, thereby creating a second sealing surface outside the annular portion for sealing the annular portion on the surface.
