Single anchor closure

Abstract

An apparatus and methods are provided for a container closure for sealing contents within an interior of a container. The container closure comprises a closure portion that is coupled to a tamper evidence band by a single anchor. The anchor is configured to keep the closure portion coupled with the tamper evidence band. The closure portion threadably engages with a finish portion of the container and seals contents in the interior of the container. The tamper evidence band remains engaged with the finish portion when the closure portion is removed from the finish portion. A multiplicity of thin connections between the tamper evidence band and the closure portion break apart when the closure portion is untightened from the finish portion. The anchor remains unbroken and allows the closure portion to be tilted away from the finish portion.

1 . A closure for sealing contents within an interior of a container, the closure comprising:
 a closure portion having a closed end, a sidewall extending from the closed end, and an open end defined by a sidewall perimeter, wherein an axis extends through a central portion of the closed end normal thereto, the closure portion configured for threadably engaging with a finish portion of the container;   a tamper evidence band for engaging with the finish portion; and   an anchor coupling the tamper evidence band to the sidewall, the anchor defining a first edge and a second edge spaced circumferentially from the first edge, the first and second edges extending parallel to the axis, the anchor configured to remain coupled to the closure portion and to the tamper evidence band subsequent to the closure portion being removed from the finish portion.   
     
     
         2 . The closure of  claim 1 , wherein the sidewall includes a multiplicity of circumferentially spaced thin connections coupling the tamper evidence band to the closure portion and configured to separate from one of the closure portion or tamper evidence band in response to loosening of the closure portion from the finish portion. 
     
     
         3 . The closure of  claim 2 , wherein the tamper evidence band is configured to remain engaged with the finish portion subsequent to the closure portion being removed from the finish portion. 
     
     
         4 . The closure of  claim 2 , wherein the anchor is configured such that only the thin connections separate from one of the closure portion or the tamper evidence band during loosening of the closure portion. 
     
     
         5 . The closure of  claim 4 , wherein the anchor is formed during injection-molding by allowing material comprising the closure to remain disposed between a pair of adjacent thin connections. 
     
     
         6 . The closure of  claim 1 , wherein the anchor comprises a single piece of material in continuous communication with the sidewall and the tamper evidence band to directly couple the tamper evidence band and the closure portion. 
     
     
         7 . (canceled) 
     
     
         8 . The closure of  claim 1 , wherein the closure portion is pivotable with respect to the tamper evidence band about a single pivot point positioned between the first and second edges of the anchor. 
     
     
         9 . (canceled) 
     
     
         10 . A method for a closure to seal contents within an interior of a container, the method comprising:
 forming a closure including a closure portion having a closed end, a sidewall extending from the closed end, an open end defined by a sidewall perimeter, and a tamper evidence band for engaging with a finish portion of the container, wherein an axis extends through a central portion of the closed end normal thereto, and wherein the closure portion is threadably engaged with the finish portion of the container;   forming a plurality of spaces in a circumferential direction between the closure portion and the tamper evidence band to define a multiplicity of thin connections and an anchor, wherein the thin connections are configured to separate from one of the closure portion or tamper evidence band in response to loosening of the closure portion from the finish portion, and wherein the anchor is formed by not forming a plurality of spaces in a predefined area in the circumferential direction between the closure portion and the tamper evidence band.   
     
     
         11 . The method of  claim 10 , wherein forming includes configuring the anchor to keep the closure portion attached to the finish portion subsequent to the closure portion being removed from the finish portion. 
     
     
         12 . The method of  claim 10 , wherein forming includes configuring the closure portion to be pivotable with respect to the tamper evidence band about a single pivot point. 
     
     
         13 . The method of  claim 10 , wherein forming includes forming the anchor as a single piece of material in continuous communication with the tamper evidence band and the sidewall. 
     
     
         14 . (canceled) 
     
     
         15 . (canceled) 
     
     
         16 . (canceled) 
     
     
         17 . (canceled) 
     
     
         18 . (canceled) 
     
     
         19 . A closure for sealing contents within an interior of a container, the closure comprising:
 a closure portion having a closed end, a sidewall extending from the closed end, and an open end defined by a sidewall perimeter, wherein an axis extends through a central portion of the closed end normal thereto, the closure portion configured for threadably engaging with a finish portion of the container;   a tamper evidence band for engaging with the finish portion;   a multiplicity of circumferentially spaced thin connections coupling the tamper evidence band to the closure portion;   a single anchor coupling the tamper evidence band to the sidewall, the anchor defining a first edge and a second edge spaced circumferentially from the first edge; and   a plurality of apertures formed in the circumferential direction between the closure portion and the tamper evidence band to separate the anchor and each of the thin connections, the apertures being uniformly spaced between the first edge and second edge of the anchor at a uniform height relative to the closed end of the closure portion.   
     
     
         20 . The closure of  claim 19 , wherein the first and second edges of the anchor extend parallel to the axis. 
     
     
         21 . The closure of  claim 19 , wherein each aperture is identical to each other aperture. 
     
     
         22 . The closure of  claim 19 , wherein the anchor comprises a single piece of material in continuous communication with the sidewall and the tamper evidence band to directly couple the tamper evidence band and the closure portion. 
     
     
         23 . The closure of  claim 19 , wherein the closure portion is pivotable with respect to the tamper evidence band about a single pivot point.
