Tamper-evident dispensing closure with partial breakaway cover

Abstract

A closure structure includes a closure body having a deck and depending sidewall, and a dispensing orifice through said deck. A closure cap has a lid part attached by a hinge to the body, and a cover part frangibly connected to the lid part, on a side of the lid part opposite the hinge. The lid part is latched to the body at lateral positions located between the hinge and the cover part. The cover part covers a lifting lip extending from the lid part. Removal of the cover part exposes the lifting lip for lifting by the user to open the lid part from the closure body.

What is claimed is:  
     
         1 . A closure structure comprising: 
 a closure body having a deck and depending sidewall, and a dispensing orifice through said deck; and    a closure cap having a lid part attached to said body at a hinged attachment, and a cover part frangibly connected to said lid part on a side of said lid part opposite said hinged attachment to said body, said lid part latched to said body at lateral positions located between said hinged attachment and said cover part, said cover part covering a lifting lip extending from said lid part, removal of said cover part exposing said lifting lip.    
     
     
         2 . The closure structure according to  claim 1 , wherein said lid part comprises first side latching beads along side edges thereof, said body comprising second side latching beads along corresponding side edges thereof, said first and second side latching beads of said lid part and said body mutually engaging to latch said lid part to said body.  
     
     
         3 . The closure structure according to  claim 2 , wherein said cover part comprises a first front latching bead and said body comprises a second front latching bead, said first and second front latching beads engageable to latch said cover part to said body.  
     
     
         4 . The closure structure according to  claim 1 , wherein said cover part comprises an upright, partially annular portion, and a horizontal top wall portion.  
     
     
         5 . The closure structure according to  claim 1 , wherein said body comprises side guard walls preventing outward side displacement of said first side latching beads of said lid part.  
     
     
         6 . The closure structure according to  claim 1 , wherein said lid part comprises a first top wall, a depending first partially annular skirt bridged by a substantially planar front wall, and said cover part comprises a second top wall and second partially annular skirt, said first and second partially annular skirts completing a cap annular sidewall and said first and second top walls completing a cap top wall.  
     
     
         7 . The closure structure according to  claim 6 , wherein said lid part comprises a latching formation at opposed side positions on an edge of said first partially annular skirt, and said cover part comprises a coacting latching formation at a front position on an edge of said second partially annular skirt.  
     
     
         8 . The closure structure according to  claim 1 , wherein said cap comprises a top wall and an annular sidewall, and said lid part and said cover part of said cap are frangibly connected by a line of weakness having a top segment extending across the top wall and side segments extending down said annular sidewall from opposite ends of said top segment.  
     
     
         9 . The closure structure according to  claim 1 , wherein said body comprises side channels, said lid part having side edge portions engaged into said side channels, said side edge portions and said side channels having latching elements for latching said side edge portions into said side channels.  
     
     
         10 . The closure structure according to  claim 1 , wherein said cover part comprises a lifting tab and a first front latching element, and said body comprises a second front latching element, said first front latching element for latching said cover part to said second front latching element, said first and second latching elements disengageable by a user-applied lifting force on said tab.  
     
     
         11 . A closure structure comprising: 
 a closure body having a deck with a dispensing orifice through said deck; and    a closure cap mounted on said closure body and having a lid part and a cover part connected together by a frangible feature, said lid part latched to said closure body and having a lid portion arranged to cover said dispensing orifice in a closed position and to open said orifice when said lid part is moved to an open position, said lid part including a lifting lip that is covered by said cover part and is exposed when said cover part is broken along said frangible feature and removed.    
     
     
         12 . The closure structure according to  claim 11 , wherein said cover part is latched to said closure body.  
     
     
         13 . The closure structure according to  claim 11 , wherein said lid part is connected to said closure body at a 0 degree location about a central axis of said closure body, and is connected by latching to said closure body at 90 degrees and 270 degrees locations about a central axis of said closure body, and said cover part is arranged to be lifted at a 180 degrees location about said central axis of said closure body, removal of said cover part allowing prying up of said lifting lip and pivoting of said lid part about the connection at 0 degrees to disengage the latching at 90 degrees and 270 degrees.  
     
     
         14 . The closure structure according to  claim 13 , wherein said connection at 0 degrees comprises a hinge.  
     
     
         15 . The closure structure according to  claim 13 , wherein latching connections at 90 degrees and 270 degrees comprise releasably engageable latching beads.  
     
     
         16 . The closure structure according to  claim 13 , wherein said cover part is releasably latched to said closure body at said connection at said 180 degrees location.
