Low cost spill-resistant cup

Abstract

The improved low cost cup and container for storing and dispensing liquids has a scoop-like-baffle that separates the body of the cup with the mouth opening of the cover. It resists spilling when shaken or vibrated suddenly. When the improved cup and container is tilted for pouring, such that the liquid level inside the storage chamber of the cup chamber is higher than the liquid level at the mouth opening, no liquid pours out of the cup. The liquid starts to flow out of the mouth opening after the cup is tilted beyond a start-to-pour angle. The start-to-pour angle is reached when the cup is tilted permitting the outside air to pass through the scoop-like-baffle and into the storage chamber. The improved cup has a removable cover with a scoop-like-baffle bended downward toward the body of the cup.

1 . A cup for dispensing a liquid with less spilling, the cup comprising: 
 a cover;    a bottom opposite the cover;    a cup body disposed between the cover and the bottom;    the cup body including a liquid storage chamber;    a mouth opening disposed in the cover and a baffle bended downward on the cover projected to form a start-to-pour line and adapted to allow a liquid in the cup to flow out of the cup when the cup is tilted beyond a start-to-pour angle.    
     
     
         2 . The cup of  claim 1  wherein the mouth opening has a lowest point and the baffle has an apex point and both points are located at two different elevation of the cover.  
     
     
         3 . The cup of  claim 1  wherein the baffle is a scoop-like baffle.  
     
     
         4 . The cup of  claim 1  wherein the start-to-pour angle is greater than 45 degrees.  
     
     
         5 . The cup of  claim 1  wherein the start-to-pour angle is greater than 60 degrees.  
     
     
         6 . The cup of  claim 3  wherein the baffle has a curved surface.  
     
     
         7 . The cup of  claim 1  wherein the cover has a pinhole.  
     
     
         8 . A cup for dispensing a liquid with less spilling, the cup comprising: 
 a cover;    a mouth opening with a lowest point disposed on the cover;    a bottom opposite the cover;    a sidewall disposed between the cover and the bottom forms a liquid storage chamber;    a scoop-like-baffle bended downward from the cover forms a liquid flow area with the sidewall having an apex point;    a start-to-pour line may be drawn from the lowest point to the apex point;    the start-to-pour line forms a start-to-pour angle with a horizontal line; and    the mouth opening disposed on the cover and adapted for the liquid in the cup to flow out of the cup when the cup is tilted beyond the start-to-pour angle.    
     
     
         9 . The cup of  claim 8  wherein the liquid flow area connecting the mouth opening to the liquid storage chamber.  
     
     
         10 . The cup of  claim 8  wherein the start-to-pour angle is greater than 45 degrees.  
     
     
         11 . The cup of  claim 8  wherein the start-to-pour angle is greater than 60 degrees.  
     
     
         12 . The cup of  claim 8  wherein the scoop-like-baffle has a curved surface.  
     
     
         13 . The cup of  claim 8  wherein the cover has a pinhole.  
     
     
         14 . A cup for dispensing a liquid with less spilling, the cup comprising: 
 a cover;    a bottom opposite the cover;    a cup body disposed between the cover and the bottom;    a mouth opening in the cover;    the cup body including a liquid storage chamber;    a baffle with an opening and adapted for the liquid in the cup to flow through the baffle opening out of the mouth opening when the cup is tilted beyond a start-to-pour angle.    
     
     
         15 . The cup of  claim 14  wherein the baffle is a scoop-like baffle.  
     
     
         16 . The cup of  claim 14  wherein the start-to-pour angle is greater than 45 degrees.  
     
     
         17 . The cup of  claim 14  wherein the start-to-pour angle is greater than 60 degrees.  
     
     
         18 . The baffle of  claim 15  wherein the scoop-like-baffle has a curved surface.  
     
     
         19 . The cup of  claim 14  wherein the cover has a pinhole.
