Composite containers and methods for sealing the same

A method of sealing a container having a top opening and a bottom opening and defining an interior for storing one or more products, said method comprising;

• sealing a top membrane to the container such that the top membrane closes the top opening;
• depositing one or more products into the interior of the container through the bottom opening;
• connecting a bottom membrane to an end cap, the end cap having a central portion and a skirt;
• closing the bottom opening with the bottom membrane by engaging the end cap with the container such that the bottom membrane is between the central portion of the end cap and the container;
• and
• affixing the bottom membrane to the container such that the end cap is removable from the container independently from the bottom membrane.

A method of packaging and handling a composite container of one or more products, the method comprising:

• forming a tubular body of the container wherein the body defines an interior and includes a top end and a bottom end, and the top end defines a top opening and the bottom end defines a bottom opening;
• sealing a flexible top membrane to the top end so as to close the top opening with the top membrane;
• depositing the one or more products into the interior of the container through the bottom opening;
• engaging an end cap with an attached bottom membrane to the bottom end of the container so as to close the bottom opening and position the bottom membrane between the end cap and the bottom end of the container;
• and
• sealing the bottom membrane to the bottom end.

A method of packaging and handling a composite container of one or more products, the method comprising:

• providing a container having a body that extends from a top end to a bottom end and defines an interior, wherein the top end defines a top opening and the bottom end defines a bottom opening;
• sealing a top membrane to the top end so as to close the top opening with the top membrane;
• depositing the one or more products into the interior of the container through the bottom opening;
• sealing a bottom membrane to the bottom end so as to close the bottom opening with the bottom membrane;
• and
• engaging an end cap with the bottom end such that the end cap is held onto the bottom end and the bottom membrane is between the container and the end cap, wherein the end cap is removable from the bottom end of the container independently from the bottom membrane and is configured to be engaged with the top end of the container to reclose the top opening after removal of the top membrane.
