Drinking glass with a removable magnetic marker

Abstract

Drinking glasses are used to drink water and wine. A glass has a cup and a base. A wine glass has a cup portion, a stem and a circular base. A magnet that is attached to the drinking glass. A marker has a magnet and an ornamental side. The marker is held in place against an outer surface of the glass by the magnetic attraction of the cup magnet and the marker magnet.

1 . A drinking glass comprising:
 a cup having an inner surface for containing a beverage and an outer surface;   a cup magnet that is attached to the cup; and   a marker that includes a marker magnet;   
     wherein the marker is attached the outer surface of the cup by a magnetic attraction of the marker magnet to the cup magnet. 
   
   
       2 . The drinking glass of  claim 1  wherein the cup magnet has a thickness less than ¼ inch. 
   
   
       3 . The drinking glass of  claim 1  wherein the marker magnet has a thickness less than ¼ inch. 
   
   
       4 . The drinking glass of  claim 1  further comprising;
 an indentation in the outer surface of the cup; and   an external feature of the marker;   
     wherein the external feature of the marker engages the indentation when the marker is held against the outer surface of the cup. 
   
   
       5 . The drinking glass of  claim 4  wherein the feature of the marker is a protrusion. 
   
   
       6 . The drinking glass of  claim 1  wherein the cup magnet is mounted in or below an indentation in the outer surface of the cup. 
   
   
       7 . The drinking glass of  claim 1  wherein the cup magnet is embedded within the cup. 
   
   
       8 . The drinking glass of  claim 1  further comprising a plurality of cup magnets that are attached to the cup. 
   
   
       9 . A drinking glass comprising:
 a cup having an inner surface for containing a beverage and an outer surface;   a stem that is attached to the bottom of the cup;   a base that is attached to the bottom of the stem; and   a cup magnet that is attached to the cup, the stem or the base; and   a marker having a marker magnet;   
     wherein the marker is attached to the drinking glass by the magnetic attraction of the marker magnet and the cup magnet. 
   
   
       10 . The drinking glass of  claim 9  wherein the cup magnet is mounted in or below an indentation in the outer surface of the cup. 
   
   
       11 . The drinking glass of  claim 9  wherein the cup magnet is embedded within the cup. 
   
   
       12 . The drinking glass of  claim 9  further comprising a plurality of cup magnets that are attached to the cup. 
   
   
       13 . A drinking glass comprising:
 a cup having an inner surface for containing a beverage and an outer surface;   a magnetic material that is attached to the cup; and   a marker that includes a marker magnet;   
     wherein the marker is attached to the outer surface of the cup by a magnetic attraction of the marker magnet to the magnetic material. 
   
   
       14 . The drinking glass of  claim 13  wherein the magnetic material has a thickness less than ¼ inch. 
   
   
       15 . The drinking glass of  claim 13  wherein the magnetic material has a thickness less than ¼ inch. 
   
   
       16 . The drinking glass of  claim 13  further comprising;
 an indentation in the outer surface of the cup; and   an external feature of the marker;   
     wherein the external feature of the marker engages the indentation when the marker is held against the outer surface of the cup. 
   
   
       17 . The drinking glass of  claim 13  wherein the feature of the marker is a protrusion. 
   
   
       18 . The drinking glass of  claim 17  wherein the magnetic material is mounted in or below an indentation in the outer surface of the cup. 
   
   
       19 . The drinking glass of  claim 13  wherein the magnetic material is embedded within the cup. 
   
   
       20 . The drinking glass of  claim 13  further comprising a plurality of magnetic material pieces that are attached to the cup.
