No spill device

Abstract

A no spill device for a container is disclosed. The no-spill device includes a container and a lid. An example of the no-spill device is a cup containing liquid provided with a cup lid. The no spill function is attained by rendering the container and the lid to be communicating chambers via the liquid in the container. When the container is tilted, the level of the liquid is lower than the top of a liquid channel within the lid. The lid is configured as a chamber by providing a channel covered by a channel cover with an inlet and outlet for the liquid divided by a partition wall.

What is claimed is: 
     
         1 . A no-spill lid for a container, comprising
 a lid configured to be secured onto the container, an integrated channel within the lid forming a secondary chamber,   an inlet within the lid for receiving liquid from the container into the integrated channel,   an outlet positioned within the lid for dispensing liquid, a partition wall separating the inlet from the outlet to regulate liquid flow,   wherein the integrated channel prevents liquid from spilling through the outlet unless the liquid level within the container reaches a predetermined threshold.   
     
     
         2 . A no spill device, comprising
 a container having an interior space holding a liquid,
 a lid sealing against a top of the container, said lid having an inlet facing the interior space and an outlet for dispensing the liquid, and 
 a channel disposed in the lid and connected between the inlet and the outlet and defining a flow path for the liquid which forces the liquid through the circumferentially extending channel between the inlet and the outlet. 
   
     
     
         3 . The no spill device of  claim 1 , the circumferentially extending channel further comprising a partition wall which prevents the liquid from flowing directly between the inlet and the outlet, without flowing through the circumferentially extending channel. 
     
     
         4 . The no spill device of  claim 1 , wherein to prevent spillage through the outlet, a liquid level in the container is adjusted to stay below a top point of the circumferentially extending channel. 
     
     
         5 . The no spill device of  claim 1 , wherein the channel comprises an inner tube connected between the inlet and the outlet. 
     
     
         6 . The no spill device of  claim 4 , wherein the inner tube is inserted in a groove of the lid. 
     
     
         7 . The no spill device of  claim 4 , wherein the inner tube is covered by an inner tube cover. 
     
     
         8 . A no spill device, comprising
 a container having an interior space holding a liquid,   a lid sealing against a top of the container, said lid having an inlet facing the interior space and an outlet for dispensing the liquid, and   a straw extending through the lid and defining a flow path for the liquid which forces the liquid through a spiral section between the inlet and the outlet and prevents spillage of the liquid, unless a liquid level in the container is high enough to pass through a top point of the spiral section of the straw.   
     
     
         9 . The no-spill lid of  claim 1 , wherein the integrated channel is enclosed by a channel cover attached to the lid. 
     
     
         10 . The no-spill lid of  claim 2 , wherein the channel cover is affixed to the lid through molding, adhesive bonding, or mechanical fastening. 
     
     
         11 . The no-spill lid of  claim 1 , wherein the lid and the integrated channel are designed to maintain liquid equilibrium between the container and the channel, preventing spillage under normal tilting conditions. 
     
     
         12 . The no-spill lid of  claim 1 , further comprising a straw extending through the lid, wherein the straw includes a spiral section that forms a secondary chamber to prevent spillage. 
     
     
         13 . The no-spill lid of  claim 5 , wherein the spiral section of the straw is configured such that liquid within the straw does not reach the outlet unless the liquid level in the container exceeds a defined horizontal threshold. 
     
     
         14 . The no-spill lid of  claim 1 , wherein the lid is made from a molded plastic material and is designed for single-use or reusable applications. 
     
     
         15 . The no-spill lid of  claim 1 , wherein the container and lid together form a two-chamber system in fluid communication, ensuring controlled liquid flow. 
     
     
         16 . A method of preventing liquid spillage from a container, comprising:
 securing a no-spill lid onto the container, the lid having an integrated channel with an inlet and an outlet;   allowing liquid from the container to enter the integrated channel through the inlet;   restricting the liquid from exiting through the outlet unless the liquid level in the container exceeds a predetermined height;   utilizing a partition wall within the integrated channel to separate the inlet from the outlet to control liquid flow.   
     
     
         17 . A no-spill drinking system, comprising:
 a container for holding a liquid;   a lid configured to be secured onto the container;   an integrated channel within the lid forming a secondary chamber;   a straw extending through the lid, the straw having a curved or spiral section that functions as a secondary chamber;   
       wherein liquid flows through the system in a controlled manner to prevent spillage when the container is tilted or moved.
