Abstract

Devices and methods for filtering mixed drinks. In one embodiment, drink ingredients are placed in a mixing container and a cap is placed on top of the mixing container. The cap comprises a closed end connected with an annular open end by a surface, and has a perimeter located at the junction between the annulus and the surface. The annular open end contains perforations formed by holes or fingers that fit inside the rim of the mixing container, with the rim of the mixing container in continuous contact with the perimeter. The drink is poured and filtered by slightly lifting and tilting the cap to allow gravity to pull the liquid through the perforations, thereby filtering the drink and eliminating the need for a separate filter.

1 . A device for filtering drinks comprising
 a cap made from a solid, relatively rigid material wherein the cap comprises a closed end and an open end, wherein the open end comprises an annulus with perforations, wherein the perforations are sized to prevent particles larger than a pre-determined size from passing through,   and wherein the annulus is connected with the closed end by a surface,   and wherein the surface comprises a rigid, solid body with a perimeter that is connected with the annulus, and wherein the perimeter is sized to connect snugly with a mixing container,   and wherein the annulus has a circumference that is smaller than the perimeter.   
   
   
       2 . The device of  claim 1  wherein the perforations are formed by holes located in the annulus and wherein the annulus has a continuous bottom edge. 
   
   
       3 . The device of  claim 1  wherein the perforations comprises a plurality of fingers in the annulus, wherein the fingers project away from the surface, and wherein the annulus lacks a continuous bottom edge. 
   
   
       4 . The device of  claim 1  wherein the perforations are no larger than ⅜ inch. 
   
   
       5 . The device of  claim 1  wherein a gasket is located at the perimeter and wherein the mixing container is in continuous contact with the gasket when the annulus of the cap is inside the mixing container. 
   
   
       6 . The device of  claim 2  wherein a second gasket is located on the continuous bottom edge of the annulus. 
   
   
       7 . The device of  claim 6  wherein a plurality of gaskets are located on the surface. 
   
   
       8 . The device of  claim 1  wherein the mixing container is double walled. 
   
   
       9 . The device of  claim 1  wherein the mixing container is single walled. 
   
   
       10 . A device for filtering drinks comprising
 a mixing container made of a solid, relatively rigid material connected with a rim, wherein the mixing container is sized to receive drink ingredients,   wherein the rim comprises an annulus with perforations, and wherein the perforations are sized to prevent particles larger than a pre-determined size from passing through,   and wherein the annulus is sized to connect snugly with a cap with an open end with a circumference.   
   
   
       11 . The device of  claim 10  wherein the perforations are formed by a plurality of holes in the annulus. 
   
   
       12 . The device of  claim 10  wherein the perforations are formed by a plurality of ridges in the annulus. 
   
   
       13 . The device of  claim 10  wherein the perforations are no larger than ⅜/inch 
   
   
       14 . The device of  claim 10  wherein the cap has a perimeter with a circumference and the perimeter circumference is greater than the circumference of the open end. 
   
   
       15 . A method of preparing a mixed drink comprising
 combining drink ingredients in a mixing container with a rim,   obtaining a cap made from a solid, relatively rigid material wherein the cap comprises a closed end and an open end, wherein the open end comprises an annulus with perforations, wherein the perforations are sized to prevent particles larger than a pre-determined size from passing through, and wherein the annulus is connected with the closed end by a surface, and wherein the surface comprises a rigid, solid body with a perimeter that is connected with the annulus, and wherein the perimeter is sized to connect snugly with a mixing container, and wherein the annulus has a circumference that is smaller than the perimeter,   placing the cap on the mixing container so that the perimeter of the cap connects snugly with rim of the mixing container,   shaking the mixing container connected with the cap to sufficiently mix the drink ingredients,   tilting and slightly lifting the cap from the rim of the mixing container to expose some of the perforations in the annulus while keeping the cap in contact with the mixing container,   tilting the mixing container and cap together to pour the mixed drink ingredients into a receptacle.
