Abstract

Another embodiment of the present invention describes a dome lid having two drink openings on the rim portion, one with an ordinary opening and the other with a narrow opening equipped with a cooling chamber to regulate hot drink before reaches the mouth. The dome lids have an added future recessed cup holder to securely hold a second cup placed on top of the dome lid which prevent falls and spills. In addition, the cup is equipped with bellowed walls in horizontal four stripes in symmetry creating four vertical walls to strengthen the cup pressure from the above, at the same time reduce fingers touching cup sidewall area heated by hot liquids.

Claims

exact text as granted — not AI-modified
1 . A disposable dome lid for placement onto a drinking cup having a narrow drink opening and a larger drink opening on opposite side on a circular planar top rim surface;
 wherein said circular top planar rim surface is extended downwardly to form inner circular side wall and outer circular side wall;   wherein said outer circular side wall extends downwardly from said top rim surface, and form circular cup rim gripper and outer circular apron;   wherein said inner circular side wall extends downwardly from said top rim surface to slightly above the cup rim gripping recess region to form a circular planar top surface;   wherein said narrow drink opening equips with a cooling chamber;   wherein said cooling chamber is created by a plastic sheet, equipped with multiple small puncture holes, forming a chamber with said outer, inner circular walls and with said circular planar top rim to cover said narrow drink opening from inside;   wherein said cooling chamber equips with external air take small holes on said inner circular wall on both side away from said narrow drink opening in symmetry.   
     
     
         2 . The disposable dome lid of  claim 1 , wherein said circular planar top surface forms cup bottom holding recess in between said inner circular sidewall and the plural cup bottom locking stubs positioned evenly around said circular planar top surface to grip a secondary cup bottom. 
     
     
         3 . The disposable cup bottom forms to fit securely on to said cup bottom holding recess of  claim 2 . 
     
     
         4 . The disposable cup of  claim 3  forms evenly placed sectional horizontally bellowed regions at the bottom section of cup wall where fingers generally touch and away from the cup wall lapped member, creating plain wall among said sectional horizontal bellowed regions to maintain said cup wall strength from pressure above.
