Secure Resealable Container Closure

Abstract

A closure including a crown member, a base member attached to the crown member, the base member having a partially frangible member and a tap member retained by the crown member and base member. The crown member is configured to move axially with respect to the base member.

1 . A method of opening a closure comprising:
 rotating a crown member of a closure;   depressing the crown member toward a base member of the closure; and   piercing at least one frangible segment of a partially frangible member of the base member.   
   
   
       2 . The method of  claim 1 , wherein a content of a container is released through a passage resulting from at least piercing the at least one frangible segment. 
   
   
       3 . The method of  claim 2 , wherein the resulting passage is resealable. 
   
   
       4 . The method of  claim 1 , wherein the crown member is rotated with respect to the base member to allow form axial movement of the crown member. 
   
   
       5 . The method of  claim 4 , wherein rotating the crown member disengages locking mechanisms of the crown and base members. 
   
   
       6 . The method of  claim 1 , wherein piercing the partially frangible member of the base member comprises impacting the crown on a surface. 
   
   
       7 . The method of  claim 1 , wherein a tap member is driven by the crown member to pierce the partially frangible member. 
   
   
       8 . The method of  claim 1 , wherein the crown member pierces the partially frangible member. 
   
   
       9 . A closure comprising:
 a crown member;   a base member attached to the crown member, the base member having a partially frangible member; and   a tap member retained by the crown member and base member;   wherein the crown member is configured to move axially with respect to the base member.   
   
   
       10 . The closure of  claim 9 , wherein the crown member is further configured to drive the tap member through the partially frangible member. 
   
   
       11 . The closure of  claim 9 , wherein the crown member is configured to pierce the partially frangible member. 
   
   
       12 . The closure of  claim 9 , wherein the frangible member includes segments hingably attached to the base member. 
   
   
       13 . The closure of  claim 9 , wherein the crown member further comprises an outer frangible or deformable skirt portion for minimizing unintentional actuation of the crown member. 
   
   
       14 . The closure of  claim 9 , wherein a skirt of the base member engages a container for removably attaching the closure to the container, the skirt having contact portions to provide seal(s) between the closure and the container. 
   
   
       15 . The closure of  claim 9 , wherein the closure is configured so the crown member remains engaged with the base member after actuation to prevent a content of an attached container from escaping through the closure. 
   
   
       16 . The closure of  claim 9 , wherein the crown and base members each include locking mechanisms which when engaged minimize unintentional actuation of the crown member. 
   
   
       17 . A closure comprising:
 a base member; and   a crown member slidably engaged with the base member, the crown member being configured to drive a tap member through a partially frangible member of the base member.   
   
   
       18 . The container closure of  claim 17 , wherein the tap member is slidably engaged within a cavity of the base member and retained by the crown member, the tap member being configured to snap into a groove of the base member for retaining the tap member upon actuation of the crown and tap members. 
   
   
       19 . The closure of  claim 17 , wherein the frangible member includes segments hingably attached to the base member. 
   
   
       20 . The closure of  claim 17 , wherein the crown member further comprises an outer frangible or deformable skirt portion for minimizing unintentional actuation of the crown member. 
   
   
       21 . The closure of  claim 17 , wherein axial movement of the crown member after actuation interacts with the tap member to prevent or allow passage of the content of the attached container to pass through the closure. 
   
   
       22 . The closure of  claim 17 , wherein a skirt of the base member engages a container for removably attaching the closure to the container, the skirt having contact portions to provide seal(s) between the closure and the container.
