Closure

Abstract

A cap is provided for coupling to a container. The cap includes a closure and an insert that may be coupled together prior to affixing the cap to a container. The insert may include a removable wall coupled to a pull tab, the removable wall detaching from the insert in response to a user pulling on the pull tab.

What is claimed is: 
     
         1 . A method of applying a closure to a container neck, the method comprising:
 providing an overcap comprising a body and a lid pivotally coupled to the body via a hinge;   providing an insert, the insert comprising:
 a first cylindrical wall; and 
 a removable separation wall coupled to a pull tab and detachably coupled to the first cylindrical wall; 
   frictionally engaging the overcap with the insert such that the overcap is biased to remain coupled to the insert, the overcap and the insert sharing a rotational axis;   providing a container comprising a container neck; and   frictionally engaging the insert with the container neck such that the insert blocks fluid communication between an interior of the container and an exterior of the container.   
     
     
         2 . The method of  claim 1 , the insert comprising a second cylindrical wall radially further from the rotational axis than the first cylindrical wall, wherein frictionally engaging the insert with the container neck comprises the second cylindrical wall engaging the container neck. 
     
     
         3 . The method of  claim 1 , comprising sterilizing the insert subsequent to engaging the insert with the container neck. 
     
     
         4 . The method of  claim 1 , comprising engaging the overcap and the insert prior to engaging the insert with the container neck. 
     
     
         5 . The method of  claim 1 , wherein the body comprises an opening that provides fluid communication between the interior of the container and the exterior of the container, the insert comprising a third cylindrical wall that extends away from the container and that extends circumferentially around the rotational axis. 
     
     
         6 . The method of  claim 5 , wherein the insert comprises a spout wall that extends away from the insert, wherein the spout wall is closer to the rotational axis than the third cylindrical wall. 
     
     
         7 . The method of  claim 1 , the body comprising helical threading extending inward towards the rotational axis, the threading engaging the container neck. 
     
     
         8 . The method of  claim 1 , the body comprising a J-band interfacing with the container neck to bias the overcap to remain coupled to the container neck. 
     
     
         9 . The method of  claim 1 , wherein the body comprises an opening that provides fluid communication between the interior of the container and the exterior of the container, the lid actuating between an open position and a closed position with respect to the body such that the lid prevents fluid communication between the interior of the container and the exterior of the container when the lid is in the closed position, and the lid does not prevent fluid communication between the interior of the container and the exterior of the container when the lid is in the open position. 
     
     
         10 . The method of  claim 1 , wherein the overcap is formed from a first material comprising LDPE. 
     
     
         11 . The method of  claim 10 , wherein the container is formed from a second material selected from the group consisting of HDPE and PP. 
     
     
         12 . A method of applying a closure to a container neck, the method comprising:
 providing an overcap comprising a body and a lid pivotally coupled to the body via a hinge, the body comprising a first cylindrical wall and a first protrusion extending inward from the first cylindrical wall;   providing an insert comprising a second cylindrical wall and a second protrusion extending outward from the second cylindrical wall;   engaging the overcap with the insert such that the first protrusion interfacing with the second protrusion biases the overcap to remain coupled to the insert, the overcap and the insert sharing a rotational axis;   providing a container comprising a container neck; and   engaging the insert with the container neck such that the insert blocks fluid communication between an interior of the container and an exterior of the container.   
     
     
         13 . The method of  claim 12 , comprising engaging the overcap and the insert prior to engaging the insert with the container neck. 
     
     
         14 . The method of  claim 12 , wherein the body comprises an opening that provides fluid communication between the interior of the container and the exterior of the container, the body comprising a third cylindrical wall that extends away from the insert and that extends circumferentially around the rotational axis, and wherein the body comprises a spout wall that extends away from the insert, wherein the spout wall is closer to the rotational axis than the third cylindrical wall. 
     
     
         15 . The method of  claim 12 , the body comprising helical threading extending inward towards the rotational axis, the threading engaging the container neck, and the body comprising a J-band interfacing with the container neck to bias the overcap to remain coupled to the container neck. 
     
     
         16 . The method of  claim 12 , wherein the body comprises an opening that provides fluid communication between the interior of the container and the exterior of the container, the lid actuating between an open position and a closed position with respect to the body such that the lid prevents fluid communication between the interior of the container and the exterior of the container when the lid is in the closed position, and the lid does not prevent fluid communication between the interior of the container and the exterior of the container when the lid is in the open position. 
     
     
         17 . The method of  claim 12 , wherein the overcap is formed from a first material comprising LDPE, and wherein the container is formed from a second material selected from the group consisting of HDPE and PP. 
     
     
         18 . A closure comprising:
 an overcap comprising a body and a lid pivotally coupled to the body via a hinge; and   an insert frictionally engaged with the body of the closure, the overcap and insert sharing a rotational axis, the insert configured to engage with a container neck subsequent to the insert engaging with the closure.   
     
     
         19 . The closure of  claim 18 , the body comprising a first cylindrical wall and a first protrusion extending inward from the first cylindrical wall, the insert comprising a second cylindrical wall and a second protrusion extending outward from the second cylindrical wall, wherein the first protrusion interfacing with the second protrusion biases the overcap to remain coupled to the insert. 
     
     
         20 . The closure of  claim 18 , wherein the overcap is formed from a first material comprising LDPE, wherein the container neck is formed from a second material selected from the group consisting of HDPE and PP.
