Dispenser with plural product chambers for separate storage and intermixing of products prior to use, and related method

A dispenser including

• a generally cylindrical sealed chamber for aseptically receiving and storing therein a liquid product,
• a dispensing device, and
• a sealing ring,
• wherein the sealing ring is adapted to engage with the chamber so as to provide a hermetically sealed enclosed mixing space bounded by an end wall of the chamber, a wall of the dispensing device and the sealing ring,
• wherein the enclosed mixing space is adapted to receive an additive for the liquid product and is operable to open the chamber and permit the liquid to mix with the additive in the mixing space and be dispensed to the exterior through the dispensing device,
• wherein at least a portion of the wall of the dispensing device is penetrable by an injection member to form an aperture through which the additive may be introduced into the mixing space, and
• wherein the dispenser is configured for the hermetically sealed enclosed mixing space to be filled when the sealed chamber and the hermetically sealed enclosed mixing space are assembled and hermetically sealed with respect to each other.

A dispenser comprising:

• first means for forming a first hermetically sealed chamber and for aseptically storing therein a first liquid product;
• second means for forming a second hermetically sealed chamber and for aseptically storing therein a second product;
• third means in fluid communication with the second hermetically sealed chamber for receiving a filling member, aseptically filling the second hermetically sealed chamber with a second product therethrough, and resealing after aseptically filling therethrough for hermetically sealing the second product within the second chamber;
• fourth means for moving at least one of the first means and the second means relative to the other between (i) a storage state in which the first and second chambers are hermetically sealed relative to each other for preventing intermixing of the first and second products, and (ii) a dispensing state in which the first and second chambers are in fluid communication with each other for intermixing and dispensing of the intermixed first and second products;
• and
• fifth means in fluid communication with at least one of the first and second chambers in the dispensing state for dispensing the intermixed first and second products therethrough,
• wherein the dispenser is configured for the second hermetically sealed chamber to be filled when the first means and the second means are assembled and the first and second chambers are hermetically sealed relative to each other.

A method comprising the following steps:

• providing a device including a first body portion defining a first chamber;
• a second body portion defining a second hermetically sealed chamber and a second filling portion in fluid communication with the second chamber;
• wherein the first and second chambers define a storage state in which the first and second chambers are hermetically sealed relative to each other, and a dispensing state in which the first and second chambers are in fluid communication with each other, wherein the device is configured for the second hermetically sealed chamber to be filled when the first body portion and the second body portion are assembled and the first and second chambers are hermetically sealed relative to each other;
• hermetically sealing within the first chamber a first liquid product;
• introducing a filling member into the second filling portion and aseptically filling the second hermetically sealed chamber with a second liquid product therethrough;
• and
• removing the filling member from the second filling portion and resealing the second filling portion to hermetically seal the second liquid product therein.
