Water shedding designs for receptacle bottoms

Abstract

A design for water shedding receptacle bottoms is presented in this invention. For ease in understanding, the specific case of a water shedding mug is presented and described in detail. The mug is designed such that water will run off the bottom of the mug when it is inverted in a dishwasher. The design is comprised of a convex bottom, a series of raised curvilinear forms radiating outward from the center of the bottom of the mug, and an associated high point on each curvilinear form at or near the periphery of the inverted mug. The convex bottom and raised curvilinear forms to form flow channels through which water will flow via normal gravitational forces when the mug is inverted in a dishwasher.

1 . A drinking mug comprising an convex external bottom, at least four curvilinear forms radiating outward from the center of the external bottom outward toward the periphery, at least four flow channels formed by the curvilinear forms and said convex external bottom, and a high point at or near the periphery of each such curvilinear form that is slightly higher than the highest point of the inverted convex external bottom, that are so configured such that water runs off the bottom of the external periphery of the mug when the mug is inverted.  
   
   
       2 . A drinking mug as in  claim 1  where the external bottom of the mug is coated with a water repellent material to enhance the flow of water through the flow channels.  
   
   
       3 . A drinking glass comprising an convex external bottom, at least four curvilinear forms radiating outward from the center of the external bottom outward toward the periphery, at least four flow channels formed by the curvilinear forms and said convex external bottom, and a high point at or near the periphery of each such curvilinear form that is slightly higher than the highest point of the inverted convex external bottom, that are so configured such that water runs off the bottom of the external periphery of the drinking glass when the glass is inverted.  
   
   
       4 . A drinking glass as in  claim 3  where the external bottom of the glass is coated with a water repellent material to enhance the flow of water through the flow channels.  
   
   
       5 . A kitchen bowl comprising an convex external bottom, at least four curvilinear forms radiating outward from the center of the external bottom outward toward the periphery, at least four flow channels formed by the curvilinear forms and said convex external bottom, and a high point at or near the periphery of each such curvilinear form that is slightly higher than the highest point of the inverted convex external bottom, that are so configured such that water runs off the bottom of the external periphery of the kitchen bowl when the kitchen bowl is inverted.  
   
   
       6 . A kitchen bowl as in  claim 5  where the external bottom of the mug is coated with a water repellent material to enhance the flow of water through the flow channels.
