Container and method and apparatus for adding a product to a container

An apparatus for filling a container with a product, the apparatus comprising:

• a filling chamber configured to receive at least a part of the container in an intermediate configuration where an aperture of the container for receiving the product is closed by a seal assembly comprising a seal support member and a seal having a flexible substrate attached to the seal support member by means of a breakable bond to allow separation of the seal support member and seal, the seal assembly being attached to the container via the seal support member;
• a seal assembly handler configured to attach to and move the seal support member relative to the container to separate the seal assembly from the container to open the container for filling of the container with the product and to replace the seal assembly on the container after addition of the product into the container to close the aperture;
• and
• a product supply member configured to add the product to an interior of the container;
• the apparatus being further configured to apply energy to the seal assembly to break the bond to allow separation of the seal support member from the seal, to remove the seal support member, and to create a seal between the seal and the container so that the container adopts a filled configuration sealed by the seal alone without the seal support member present.
