Abstract: A collapsible food and beverage container, including a body having an open top, a thickened neck connecting the open top to a flexible reservoir having an interior configured to receive food or beverage, the reservoir having a vertical shape with thin and flexible front and rear sidewalls squeezable toward one another to expel food or beverage from the reservoir via the open top, thickened side flanges and a base, the thickened side flanges extending continuously from the base of the reservoir to the neck of the body to support and maintain the vertical shape of the reservoir to enable the reservoir to stand while static and full of food or beverage, and to avoid vertical collapse of the reservoir when the reservoir is squeezed to dispense food or beverage from the container.

Abstract: A barrier system for a container, includes a fluid permeable solids barrier comprising an outer flange surrounding a central fluid permeable sieve; an upper port located at an interior edge of an upper side of the outer flange, a lower port on an opposite lower side of the outer flange in fluid communication with the upper port by a flow path therebetween, and a fluid permeable sieve located in the flow path between the upper port and the lower port. The system also includes a straw having an upper end configured to fittingly engage the lower port of the fluid permeable solids barrier spout; and a spout having a lower port configured to fittingly engage the upper port of the fluid permeable solids barrier.
