Total Claims: 5
Claim 1
Independent Claim
164 words
A coaster comprising a base member defining a circular cavity and an upwardly directed opening to said cavity, said base member having an elongated support extending only along a single axis through the center of said cavity and extending substantially across said cavity, a projection extending into said opening to said cavity at a location higher than said elongated support, and a pair of edge supports on opposite sides of said elongated support at the same height as said elongated support, and a support plate removably mounted in said cavity so as to support a vessel on its exposed upper surface, said plate being supported by said elongated support and said edge supports, said plate having a notch adapted to pass by said projection without interference as said plate is moved through said opening, said plate being mounted for rotatable movement when below said projection to move a portion of said plate under said projection so as to interfere with removal of said plate.
