CONTAINER CLOSURE HAVING A SPOUT AND MEANS FOR INTRODUCING AN ADDITIVE INTO THE CONTENTS OF THE CONTAINER
First Claim
1. A closure device for use with a container having a main liquid compartment and an opening with a neck,the closure device comprising a cap member defining a fluid chamber and a plug member having a first plug portion sealingly engageable in an aperture in a bottom wall of the fluid chamber and a second plug portion sealingly engageable in a spout aperture,wherein the cap member is movable relative to the plug member to raise the cap memberfrom a closed position in which the first plug portion closes the bottom wall aperture and the second plug portion closes the spout aperture,through a first open position in which the first plug portion is at least partially withdrawn from the bottom wall aperture to provide a communication path in use from the fluid chamber to the main liquid compartment and in which the second plug portion closes the spout aperture,to a second open position in which the second plug portion is at least partially withdrawn from the spout aperture.

Abstract
A closure device which includes a fluid chamber containing an additive such as a liquid and a housing having a plug member. The cap member is provided with a primary engagement means, such as an internal thread, which engages with a corresponding primary engagement means provided on the housing, such as an external thread, to allow the cap member to be lifted relative to the housing from a closed position in which the plug member closes a bottom aperture and a spout aperture in the fluid chamber, through a first open position in which the plug member is at least partially withdrawn from the bottom aperture while still closing the spout aperture, thereby allowing the additive to pass from the fluid chamber, and to a second open position in which the spout aperture is at least partially open.

1. A closure device for use with a container having a main liquid compartment and an opening with a neck,
the closure device comprising a cap member defining a fluid chamber and a plug member having a first plug portion sealingly engageable in an aperture in a bottom wall of the fluid chamber and a second plug portion sealingly engageable in a spout aperture, wherein the cap member is movable relative to the plug member to raise the cap member from a closed position in which the first plug portion closes the bottom wall aperture and the second plug portion closes the spout aperture, through a first open position in which the first plug portion is at least partially withdrawn from the bottom wall aperture to provide a communication path in use from the fluid chamber to the main liquid compartment and in which the second plug portion closes the spout aperture, to a second open position in which the second plug portion is at least partially withdrawn from the spout aperture.

19. A container having a main liquid compartment, an opening having a neck, and a closure device closing said opening,
wherein the closure device comprises a cap member defining a fluid chamber and plug member provided in the neck of the container, the plug member having a first plug portion sealingly engageable in an aperture in a bottom wall of the fluid chamber and a second plug portion sealingly engageable in a spout aperture, wherein the cap member is moveable relative to the plug member to raise the cap member from a closed position in which the first plug portion closes the bottom wall aperture and the second plug portion closes the spout aperture, through a first open position in which the first plug portion is at least partially withdrawn from the bottom wall aperture to provide a communication path from the fluid chamber to the main liquid compartment and in which the second plug portion closes the spout aperture, to a second open position in which the second plug portion is at least partially withdrawn from the spout aperture.

39. A method of introducing an additive liquid into a main liquid compartment of a container having an opening with a neck, the method comprising the steps of
raising a cap member of a closure device and a fluid chamber defined by said cap member relative to a plug member from a closed position, in which an aperture provided in a bottom wall of said fluid chamber is closed by a first plug portion of said plug member and a spout aperture provided in said fluid chamber is closed by a second plug portion of said plug member, to a first open position, in which said first plug portion is at least partially withdrawn from said bottom wall aperture to provide a communication path from said fluid chamber to said main liquid compartment and in which said spout aperture remains closed by said second plug portion, releasing pressurised additive liquid from said fluid chamber along said communication path into said main liquid compartment, and raising said cap member further relative to said plug member to a second open position, in which said second plug portion is at least partially withdrawn from said spout aperture to provide a communication path from said fluid chamber through said spout aperture.
