Apparatus, systems and methods for dispensing drinks, food, and other liquids

A self-emptying container having a plurality of structural elements, the plurality of structural elements comprising:

• a top;
• a bottom;
• a plurality of vertical walls extending between the bottom and the top;
• an inner bag for holding contents to be dispensed;
• a female coupling configured to receive and establish a friction seal with a male coupling of an external device for inserting or extracting the contents to or from the container through a pour spout associated with the female and male couplings after the friction seal is established between the female and male couplings;
• and at least one panel positioned inside the container and configured to move in a first direction away from a center of the container or a second direction towards the center of the container;
• a compressible element associated with the at least one panel wherein during filling of the inner bag the compressible element is compressed and the at least one panel moves in the first direction;
• and wherein during emptying of the inner bag the compressible element is decompressed and the at least one panel moves in the second direction;
• thus causing the at least one panel to exercise pressure onto the inner bag, and thus, helping to empty the inner bag.
