Insect-repelling beverage receptacle attachment

Abstract

A rubberized food-grade device temporarily attaches to a beverage receptacle, preventing insects from entering the beverage but allowing individuals to drink from the receptacle freely. Different devices are contemplated for attachment to bottles, cans, or drinking glasses and are shaped in novel ways.

What is claimed is: 
     
         1 . A snugly fitting attachable device for a beverage receptacle that has:
 a perforated opening intended to prevent insects from entering the receptacle but allowing liquid to exit the receptacle,   said attachable device being temporarily affixed to the beverage receptacle after opening or filling the receptacle.   
     
     
         2 . The system of  claim 1 , wherein the attachable device affixes to an opened beverage bottle. 
     
     
         3 . The system of  claim 1 , wherein the attachable device affixes to an opened beverage can. 
     
     
         4 . The system of  claim 1 , wherein the attachable device affixes to a drinking glass filled with beverage to be consumed. 
     
     
         5 . The system of  claim 1 , wherein the perforated opening comprises curved or straight vanes crossing a hole. 
     
     
         6 . The system of  claim 1 , wherein the perforated opening comprises a mesh crossing a hole. 
     
     
         7 . The system of  claim 1 , wherein the perforated opening comprises a plurality of small holes. 
     
     
         8 . The system of  claim 1 , wherein the attachable device is comprised of silicone rubber. 
     
     
         9 . The system of  claim 1 , wherein the attachable device is comprised of flexible plastic such as ABS. 
     
     
         10 . The system of  claim 1 , wherein the attachable device is comprised of biodegradable material such as PLA. 
     
     
         11 . The system of  claim 1 , wherein the perforated opening is contoured and sized to promote laminar instead of turbulent flow as the beverage exits. 
     
     
         12 . The system of  claim 1 , wherein the perforated opening is contoured and sized to promote turbulent flow instead of laminar flow as the beverage exits. 
     
     
         13 . The system of  claim 1 , wherein the perforated opening is shaped and sized to prevent unwanted insertion of drugs or other contaminants into the open beverage. 
     
     
         14 . The system of  claim 1 , wherein a tab is present to attach a tether for securing the attachable device to the user's clothing, the receptacle itself, or other accessory. 
     
     
         15 . The system of  claim 1 , wherein each attachable device in a group of the attachable devices is colored or marked to allow easy identification of each individual's drink. 
     
     
         16 . The system of  claim 1 , wherein the attachable device has a flattened and/or lightened region on which a name or other identifier may be temporarily marked. 
     
     
         17 . The system of  claim 2 , wherein the attachable device affixing to a bottle is itself shaped like the spout of a bottle. 
     
     
         18 . The system of  claim 3 , wherein the attachable device affixes to a can but an extended portion is shaped like the spout of a bottle. 
     
     
         19 . The system of  claim 1 , wherein the attachable device has a novel shape representing a recognizable inanimate object, plant, part of a plant, animal, or part of an animal. 
     
     
         20 . The system of  claim 1 , wherein a cap is removably attached to the mouth-side opening of the attachable device to re-seal the beverage receptacle temporarily.
