Surface energy modification for wetting substances

Abstract

A container comprising a finish, a sidewall portion extending from the finish, a base portion extending from the sidewall portion and enclosing the sidewall portion to form a volume therein for retaining a commodity, and a coating disposed along at least a portion of the finish, the sidewall portion, or the base portion for providing a low-energy surface for improved dispensing of the commodity.

1 . A container comprising:
 a finish;   a sidewall portion extending from said finish;   a base portion extending from said sidewall portion and enclosing said sidewall portion to form a volume therein for retaining a commodity;   a coating disposed along at least a portion of said finish, said sidewall portion, or said base portion for providing a low-energy surface for improved dispensing of the commodity.   
     
     
         2 . The container according to  claim 1  wherein said coating is disposed within said volume. 
     
     
         3 . The container according to  claim 1  wherein said coating comprises a first layer. 
     
     
         4 . The container according to  claim 3  wherein said first layer is made of hexamethyldisilazane. 
     
     
         5 . The container according to  claim 1  wherein said coating comprises:
 a first layer; 
 a second layer adhered to said first layer; and 
 a third layer adhered to said second layer. 
 
     
     
         6 . The container according to  claim 5  wherein said first layer is made of hexamethyldisilazane, said second layer is made of hexamethyldisiloxane, and said third layer is made of hexamethyldisilazane. 
     
     
         7 . The container according to  claim 1  wherein said coating is made of a recyclable material. 
     
     
         8 . A container comprising:
 a finish;   a sidewall portion extending from said finish;   a base portion extending from said sidewall portion and enclosing said sidewall portion to form a volume therein for retaining a commodity;   a multi-layer coating disposed along at least a portion of said finish, said sidewall portion, or said base portion for providing a low-energy surface for improved dispensing of the commodity.   
     
     
         9 . The container according to  claim 8  wherein at least one of the layers of said multi-layer coating comprises hexamethyldisilazane. 
     
     
         10 . The container according to  claim 8  wherein said multi-layer coating comprises hexamethyldisilazane and hexamethyldisiloxane. 
     
     
         11 . The container according to  claim 8  wherein said multi-layer coating is made of recyclable material. 
     
     
         12 . A container comprising:
 a finish;   a sidewall portion extending from said finish;   a base portion extending from said sidewall portion and enclosing said sidewall portion to form a volume therein for retaining a commodity;   a coating disposed along said sidewall portion and said base portion for providing a low-energy surface for improved dispensing of the commodity.   
     
     
         13 . The container according to  claim 12  wherein said coating is a multi-layer coating. 
     
     
         14 . The container according to  claim 12  wherein said coating comprises hexamethyldisilazane. 
     
     
         15 . The container according to  claim 12  wherein said coating comprises hexamethyldisilazane and hexamethyldisiloxane. 
     
     
         16 . The container according to  claim 12  wherein said coating is made of recyclable material.
