Woven mesh and uses

Abstract

The present invention relates to a woven mesh. The woven mesh comprises polyester such as poly(ethylene terephthalate). The present invention also relates to associated uses and systems of the woven mesh.

1 . A device to produce multiple serves of a consumable liquid, wherein the device comprises woven mesh substantially comprising polyester. 
     
     
         2 . The device of  claim 1 , wherein the polyester comprises at least one of Polyglycolide, Polyglycolic acid, Polylactic acid, Polycaprolactone, Polyethylene adipate, Polyhydroxyalkanoate, Poly(ethylene terephthalate) (PET), Polybutylene terephthalate, Polytrimethylene terephthalate, Polyethylene naphthalate and Vectran. 
     
     
         3 . The device of  claim 2 , wherein the polyester is PET. 
     
     
         4 . The device of  claim 3  wherein the device is in the form of a filter or a pillowpack. 
     
     
         5 . The device of  claim 4 , wherein the pillowpack seals a select material. 
     
     
         6 . The device of  claim 5 , wherein the select material is any plant part that is infused to produce the consumable liquid. 
     
     
         7 . The device of  claim 6 , wherein the plant part is seeds, leaves, dried herbs, flowers, fruits, berries or any combination thereof. 
     
     
         8 . The device of  claim 7 , wherein the seeds are coffee beans in the form of coffee grinds. 
     
     
         9 . The device of  claim 7 , wherein the leaves are tea leaves. 
     
     
         10 . The device of  claim 5 , wherein the mesh is sealed by sealing means. 
     
     
         11 . The device of  claim 10 , wherein means to seal the mesh is via ultrasonic welding and/or direct heat. 
     
     
         12 . The device of  claim 11 , wherein ultrasonic welding comprises high frequency low amplitude vibration wherein the high frequency is within the range of about 15 kHz to about 40 kHz. 
     
     
         13 . The device of  claim 11 , wherein the temperature to directly heat seal the mesh is in a range between about 50 and about 200 degrees Celsius or in a range between about 100 to about 150 degrees Celsius or the temperature is about 125 degrees Celsius. 
     
     
         14 . The device of  claim 5 , wherein dimensions of the mesh comprise a width and length of about 50 millimetres (mm) to about 200 millimetres (mm) or a width and length of about 90 millimetres (mm) to about 120 millimetres (mm). 
     
     
         15 . A method of manufacturing a device, wherein the device comprises woven mesh substantially comprising polyester, wherein the method comprises
 (1) placing select material into the woven mesh; and   (2) sealing the woven mesh so that the select material remains in the mesh during immersion.   
     
     
         16 . A method of making multiple serves of a consumable liquid comprising:
 (1) placing the device of  claim 5  into a Bodum® or brewer or any apparatus in which the purpose of using the apparatus is to produce the consumable liquid;   (2) immersing the device into hot or cold liquid for a time and under conditions for infusion to occur wherein a consumable liquid is produced by the infusion in an amount that allows for multiple serves; and   (3) collecting the consumable liquid for multiple serve consumption.   
     
     
         17 . The method according to  claim 16 , wherein the consumable liquid is selected from the group consisting of tea, coffee and another infusion.
