Abstract
Abstract An integral web on a double suction cup vacuum holder includes the axis of a stem connecting the two suction cups. When the web is pressed inward, toward the stem, the lip of one or both of the suction cups is raised, thus spoiling the vacuum therein and releasing the holder. A diametrical hole through the stem, normal to the webs, provides convenient attachment means for inserting a pole or strap or other item. Additional items are readily attached to the pole or strap.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
144 words
In a vacuum holder having a. an arcuate suction cup with a spherical concavity, a flexible circular lip peripherally surrounding the concavity, and b. an integral stem, extending from the side of the cup opposite the spherical concavity c. the stem coaxial with the cup and the spherical cavity d. attachment means on the stem for attaching items thereto; e. An IMPROVED VACUUM BREAKER COMPRISING: f. a web of planar configuration having one edge integral with said stem and extending radially therefrom, another edge of said web extending from the intersection of said stem and said cup to said lip of said cup and being integral with said cup, g. the web aligned with the axis of the stem, h. so that when the web is pushed toward the stem it lifts the lip of the cup thus breakinng the vacuum of the cup.
