Description

Technical Field

[0002] Suction cups create a vacuum chamber by squeezing out the air inside, and utilize the pressure difference between the inside and outside to secure household items to a base surface. They are typically attached to walls, countertops, and other surfaces for hanging items. A commonly used suction cup has a body made of a rubber-coated frame, with a cover attached to the outside. The cup has a connection for hooks, etc. When in use, the cover is squeezed manually, which compresses the cup body and frame, expelling the air inside and creating a vacuum chamber. The rubber coating of the cup adheres tightly to the base surface, securing it in place.
