Bottle with constant liquid pouring device

Abstract

A bottle for dispensing constant liquid is disclosed. Removing a retaining cap from a reservoir and loosening a ring will enable a free rotation of a spout for moving a conduit vertically at a flow regulator as grip means rotates until a top opening of the conduit is flush with a predetermined mark of scale. Fastening the ring and pressing the reservoir will direct liquid to flow upward into a cup through the tube and the conduit until liquid has reached a level higher than the top opening of the conduit. Releasing the pressing will cause liquid above the top opening of the conduit to flow back to the liquid reservoir and store liquid below the top opening of the conduit in the cup. Finally, pressing and turning the reservoir upside down will discharge liquid from the cup.

1 . A bottle, comprising: 
 a flexible liquid reservoir including a neck, a cylindrical ring threadedly secured to the neck, a spout having an annular flange, and a retaining cap secured on the spout, the retaining cap being threadedly secured to the ring;    a constant liquid control device inside the liquid reservoir and comprising a staged cup including a top annular flange rested on the neck, the flange of the cup being urged the flange of the spout against inside of the ring, a scale on an outer surface of the cup, and a narrow bottom adapter, a conduit partly disposed in the cup, and a flow regulator;    a tube fastened at the adapter;    grip means extended downwardly from the spout for slidably holding the conduit,    whereby removing the retaining cap from the liquid reservoir and loosening the ring will enable a free rotation of the spout for moving the conduit upwardly or downwardly at the flow regulator as the grip means rotates until a top opening of the conduit is flush with a predetermined mark of the scale; fastening the ring and pressing the liquid reservoir will direct liquid to flow upward into the cup through the tube and the conduit until liquid has reached a level higher than the top opening of the conduit; releasing the pressing will cause liquid above the top opening of the conduit to flow back to the liquid reservoir through the conduit and the tube and store liquid below the top opening of the conduit in the cup; and pressing the liquid reservoir and turning the liquid reservoir upside down will pour liquid in the cup out of the spout.    
   
   
       2 . The bottle of  claim 1 , wherein the liquid reservoir comprises deformable flat front and rear sides.  
   
   
       3 . The bottle of  claim 1 , wherein the tube comprises an oblique surface at its bottom opening proximate a bottom of the liquid reservoir.  
   
   
       4 . The bottle of  claim 1 , wherein the conduit comprises an upper bent section.  
   
   
       5 . The bottle of  claim 1 , wherein the flow regulator comprises outer threads around the conduit and inner threads inside the adapter threadedly secured to the outer threads.
