Dual anchor container 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 first anchor and a second anchor. The first and second anchors keep the tamper evidence band coupled with the closure portion. The closure portion threadably engages with a finish portion of the container and seals contents in the interior of the container. Multiple thin connections between the tamper evidence band and the closure portion break apart when the closure portion is untightened from the finish portion. The thin connections may be arranged on opposite sides of the tamper evidence band and between the first and second anchors. The first and second anchors remain unbroken and cause the tamper evidence band to remain attached to the closure portion upon being removed from the finish portion.

What is claimed is: 
     
         1 . A closure for sealing contents within an interior of a container, the closure comprising:
 a closure portion for threadably engaging with a finish portion of the container;   a tamper evidence band for engaging with the finish portion; and   dual anchors for keeping the closure portion attached to the tamper evidence band.   
     
     
         2 . The closure of  claim 1 , wherein a multiplicity of thin connections attach the tamper evidence band to the closure portion and are configured to break apart when the closure portion is untightened from the finish portion. 
     
     
         3 . The closure of  claim 2 , wherein the tamper evidence band is configured to engage with the finish portion when the closure portion is removed from the container so as to cause the multiplicity of thin connections to break apart. 
     
     
         4 . The closure of  claim 2 , wherein the dual anchors are configured such that only the multiplicity of thin connections break apart during loosening of the closure portion. 
     
     
         5 . The closure of  claim 4 , wherein the anchors are configured to ensure that the tamper evidence band remains attached to the closure portion upon being removed from the finish portion while broken thin connections allow portions of the tamper evidence band to separate from the closure portion. 
     
     
         6 . The closure of  claim 4 , wherein the broken thin connections are configured to provide an observational indication that the closure has been unsealed from the finish portion after having been installed by a manufacturer. 
     
     
         7 . The closure of  claim 2 , wherein the dual anchors comprise a first anchor and a second anchor disposed at opposite sides of the circumference of the tamper evidence band. 
     
     
         8 . The closure of  claim 7 , wherein a first group of thin connections is disposed between the first anchor and the second anchor and a second group of thin connections is disposed between the second anchor and the first anchor. 
     
     
         9 . The closure of  claim 7 , wherein a first space separates each of the first anchor and the second anchor from adjacent thin connections. 
     
     
         10 . The closure of  claim 9 , wherein a first angle subtends the center of each of the first anchor and the second anchor and the center of an adjacent thin connection, the first angle taken with respect to the center of the circumference of the tamper evidence band. 
     
     
         11 . The closure of  claim 10 , wherein a second space separates adjacent thin connections. 
     
     
         12 . The closure of  claim 11 , wherein a second angle subtends the centers of adjacent thin connections, the second angle taken with respect to the center of the circumference of the tamper evidence band. 
     
     
         13 . A method for a closure to seal contents within an interior of a container, comprising:
 configuring a closure portion for threadably engaging with a finish portion of the container;   configuring a tamper evidence band for engaging with the finish portion; and   joining the closure portion and the tamper evidence band by way of dual anchors.   
     
     
         14 . The method of  claim 13 , wherein joining includes configuring the dual anchors to keep the closure portion attached to the tamper evidence band after the closure portion is unsealed from the container. 
     
     
         15 . The method of  claim 13 , wherein joining includes coupling the closure portion and the tamper evidence band by way of a multiplicity of thin connections configured to break apart when the closure portion is untightened from the finish portion. 
     
     
         16 . The method of  claim 15 , wherein joining includes configuring the dual anchors such that only the multiplicity of thin connections break apart during loosening of the closure portion. 
     
     
         17 . The method of  claim 13 , wherein joining includes disposing a first anchor and a second anchor at opposite sides of the circumference of the tamper evidence band. 
     
     
         18 . The method of  claim 17 , wherein disposing includes arranging a first group of thin connections between the first anchor and the second anchor along a first side of the circumference. 
     
     
         19 . The method of  claim 18 , wherein disposing further includes arranging a second group of thin connections between the second anchor and the first anchor along a second side of the circumference. 
     
     
         20 . The method of  claim 19 , wherein arranging includes using a first space to separate each of the first anchor and the second anchor from adjacent thin connections and using a second space to separate adjacent thin connections.
