Multi-piece snap-together cap

Abstract

A multi-piece snap together cap generally comprises a molded base cap and a covercap intended to be used on a flexible-walled container and in an inverted position. Neither the covercap nor the base cap require special orientation during the assembly process of the multi pieces. To assemble, the top open ring of the covercap is lowered onto the base cap. The ring is molded with a one-way negative snap-in void area that is formed with an undercut, insuring the top positive overlapping snap ring in locked in place after assembly. The top cap covercap piece is unique in its construction and combines several functional features. For instance, it is molded in the open position and connected to the top open snap ring with a living hinge, forming a single piece. When the lid is in the open position, the living hinge keeps it out of the way when product is dispensed. The top lid and snap ring also includes a second open/close friction snap ring, which keeps the top lid in a down position during storage and the internal product fresh. The top lid also provides an overhang tab so that the consumer may easily unsnap the lid with a fingertip.

1 . A closure for selective dispensing of product from a flexible-walled container, said closure comprising: 
 a base cap for attachment to said container;    a cover cap for attachment to the base cap;    a structure for retaining the cover cap in a locked position.    
     
     
         2 . The closure of  claim 1 , further comprising a circumscribing member on the cover cap to be fitted onto the base cap.  
     
     
         3 . The closure of  claim 1 , wherein said circumscribing member is expandable to be retained on the base cap.  
     
     
         4 . The closure of  claim 1 , wherein said circumscribing member is rotatable on the base cap and does not require special orientation during the assembly process of the base and cover caps.  
     
     
         5 . The closure of  claim 1 , further comprising a tab on the cover cap to facilitate the opening of the cap merely by one's finger.  
     
     
         6 . The closure of  claim 1 , wherein said cover cap further comprises a living hinge connecting a lid of the cover cap to said circumscribing member.  
     
     
         7 . The closure of  claim 6 , wherein said cover cap stays distal from the product when dispensed.  
     
     
         8 . The closure of  claim 6 , further comprising a second open/close friction snap ring which keeps the in a down position during storage and the internal product fresh.  
     
     
         9 . The closure of  claim 1 , wherein said cover cap has a different visual characteristic from the base cap or container.  
     
     
         10 . The closure of  claim 9 , wherein said different visual characteristic is color.  
     
     
         11 . The closure of  claim 1 , wherein at least a portion thereof is made from polypropylene.  
     
     
         12 . The closure of  claim 1 , further comprising an area for trapping liquid or products of differing viscosities in a channel.
