Closure for Dispensing Additive

Abstract

A closure including a base member, a top member slidably engaged with the base member, the top member having a spigot member. A crown member is slidably engaged with the top member. The base member and top member form at least one reservoir.

1 . A method for introducing reservoir contents from a closure into a content of an attached container comprising: 
 fracturing a frangible membrane of a base member of the closure with a protrusion of a top member of the closure; and    introducing the reservoir contents to the container contents through the fractured frangible membrane.    
   
   
       2 . The method of  claim 1 , further comprising fracturing a frangible membrane of the top member of the closure so that the contents of the container are released through a resulting passage through the closure.  
   
   
       3 . The method of  claim 2 , wherein the resulting passage is resealable.  
   
   
       4 . The method of  claim 1 , further comprising rotating the top member of the closure with respect to the base member of the closure to allow for a axial movement of the top member.  
   
   
       5 . The method of  claim 4 , wherein rotating the top member disengages locking mechanisms of the top and base members.  
   
   
       6 . The method of  claim 1 , wherein breaking the frangible membrane of the base member comprises exerting a force on a top of the closure.  
   
   
       7 . The method of  claim 1 , wherein the closure and the attached container are of unitary construction.  
   
   
       8 . A method for introducing reservoir contents from a closure into a content of an attached container comprising: 
 fracturing a frangible membrane of a top member of the closure with a protrusion on a spigot or crown member of the closure;    fracturing a frangible membrane of a base member of the closure with a protrusion of the top member of the closure; and    introducing the reservoir contents to the container contents through the fractured frangible membrane of the base member.    
   
   
       9 . The method of  claim 8 , wherein segments of the frangible membrane of the top member remain hingably attached to the top member after being fractured.  
   
   
       10 . The method of  claim 8 , wherein at least the frangible membranes of the top and base members contain the reservoir contents before an actuation of the closure.  
   
   
       11 . The method of  claim 8 , further comprising passing a content of the attached container through the container closure via the broken frangible membranes of the top and base members.  
   
   
       12 . The method of  claim 8 , wherein the closure and the attached container are of unitary construction.  
   
   
       13 . A closure system comprising: 
 a top member including at least one protrusion on an interior of the top member; and    a base member attached to the top member, where the top and base members form at least one reservoir for containing at least one substance;    wherein the top member is configured to move axially with respect to the base member.    
   
   
       14 . The closure system of  claim 13 , wherein the at least one protrusion on an interior of the top member is configured to fracture a frangible membrane of the base member, wherein the substance is released when the frangible membrane is fractured.  
   
   
       15 . The closure system of  claim 14 , wherein the frangible membrane includes segments hingably attached to the base member.  
   
   
       16 . The closure system of  claim 13 , wherein the top member further comprises an outer frangible or deformable skirt portion for minimizing unintentional actuation of the top member.  
   
   
       17 . The closure system of  claim 13 , 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.  
   
   
       18 . The closure system of  claim 13 , wherein the closure is configured so the top member remains engaged with the base member after actuation to prevent a content of an attached container from escaping through the closure.  
   
   
       19 . The closure system of  claim 13 , wherein the top and base members each include locking mechanisms which when engaged minimize unintentional actuation of the top member.  
   
   
       20 . The closure system of  claim 13 , wherein the base member is of unitary construction with a container into which the at least one substance is released.  
   
   
       21 . A closure system comprising: 
 a base member;    a top member slidably engaged with the base member, the top member having a spigot member; and    a crown member slidably engaged with the top member;    wherein the base member and top member form at least one reservoir.    
   
   
       22 . The closure system of  claim 21 , wherein the spigot member is slidably engaged within a cavity of the top member and retained by the crown member, the spigot member being configured to snap into a groove of the top member for retaining the spigot member upon actuation of the crown and spigot members.  
   
   
       23 . The closure system of  claim 21 , wherein when actuated, the spigot member pierces a frangible membrane on a top surface of the top member and a protrusion of the top member pierces a frangible membrane of the base member, wherein a content of the at least one reservoir is released into an attached container when the frangible membrane of the base member is broken.  
   
   
       24 . The closure system of  claim 21 , wherein when actuated, the crown member pierces a frangible membrane on a top surface of the top member and a protrusion of the top member pierces a frangible membrane of the base member, wherein a content of the at least one reservoir is released into an attached container when the frangible membrane of the base member is broken.  
   
   
       25 . The closure system of  claim 21 , wherein axial movement of the crown member after actuation interacts with the spigot member to prevent or allow passage of a content of an attached container to pass through the closure.  
   
   
       26 . The closure system of  claim 21 , wherein the base member is of unitary construction with a container into which a content of the at least one reservoir is released.  
   
   
       27 . A method of releasing a content of a reservoir comprising: 
 rotating a top member of the reservoir relative to a bottom member of the reservoir;    axially driving the top member of the reservoir so that a protrusion of the top member fractures a frangible membrane of the bottom member; and    releasing the content of the reservoir through the fractured frangible membrane.
