Multiple compartment collapsible bottle
First Claim
1. A collapsible container having an outlet opening and two collapsible tubular compartments,each compartment extending beside the other compartment from a respective open end of each compartment opening into the outlet opening away from the outlet opening to a respective closed end of each compartment,each compartment having a outboard side and an opposed inboard side with the inboard side of one compartment facing the inboard side of the other compartment,each compartment being collapsible from an inflated condition in which the container is filled with fluid toward a collapsed condition by the withdrawn of fluid from the outlet opening,wherein in the inflated condition, the inboard side and outboard side of each compartment are spaced, andwherein in collapsing from the inflated condition toward the collapsed condition the outboard side and inboard side of each compartment move relatively towards each other, a shunt opening through the inboard sides of the compartments placing the two compartments in communication through their inboard sides,the shunt comprises a plurality of shunt passageways bridging between the inboard sides of the compartments placing the two compartments in communication through their inboard sides at a plurality of locations from the open end to their closed end.

1. A collapsible container having an outlet opening and two collapsible tubular compartments,
each compartment extending beside the other compartment from a respective open end of each compartment opening into the outlet opening away from the outlet opening to a respective closed end of each compartment, each compartment having a outboard side and an opposed inboard side with the inboard side of one compartment facing the inboard side of the other compartment, each compartment being collapsible from an inflated condition in which the container is filled with fluid toward a collapsed condition by the withdrawn of fluid from the outlet opening, wherein in the inflated condition, the inboard side and outboard side of each compartment are spaced, and wherein in collapsing from the inflated condition toward the collapsed condition the outboard side and inboard side of each compartment move relatively towards each other, a shunt opening through the inboard sides of the compartments placing the two compartments in communication through their inboard sides, the shunt comprises a plurality of shunt passageways bridging between the inboard sides of the compartments placing the two compartments in communication through their inboard sides at a plurality of locations from the open end to their closed end.

7. A collapsible container having an outlet opening and two collapsible tubular compartments,
each compartment extending beside the other compartment from a respective open end of each compartment opening into the outlet opening away from the outlet opening to a respective closed end of each compartment, each compartment having a outboard side and an opposed inboard side with the inboard side of one compartment facing the inboard side of the other compartment, each compartment being collapsible from an inflated condition in which the container is filled with fluid toward a collapsed condition by the withdrawn of fluid from the outlet opening, wherein in the inflated condition, the inboard side and outboard side of each compartment are spaced, and wherein in collapsing from the inflated condition toward the collapsed condition the outboard side and inboard side of each compartment move relatively towards each other, a shunt opening through the inboard sides of the compartments placing the two compartments in communication through their inboard sides, wherein the shunt provides communication between containers in all conditions of the containers in collapsing from the inflated condition to the collapsed condition and the shunt is not collapsible.

13. A collapsible container having an outlet opening and two collapsible tubular compartments,
each compartment extending beside the other compartment from a respective open end of each compartment opening into the outlet opening away from the outlet opening to a respective closed end of each compartment, each compartment having a outboard side and an opposed inboard side with the inboard side of one compartment facing the inboard side of the other compartment, each compartment being collapsible from an inflated condition in which the container is filled with fluid toward a collapsed condition by the withdrawn of fluid from the outlet opening, wherein in the inflated condition, the inboard side and outboard side of each compartment are spaced, wherein in collapsing from the inflated condition toward the collapsed condition the outboard side and inboard side of each compartment move relatively towards each other, a shunt opening through the inboard sides of the compartments placing the two compartments in communication through their inboard sides, each compartment extends about a longitudinal axis from their open end to their respective closed end with the longitudinal axis of each compartment being parallel, the shunt includes a continuous elongate channelway extending parallel to the longitudinal axis of the compartments between the compartments, the channelway open at one end to the outlet opening, the channelway open on a first side of the channelway through the inboard side of one of the compartment into the one compartment and open on a second side of the channelway through the inboard side of a second of the compartments into the second compartment, wherein the channelway is generally cylindrical about a channelway axis parallel the longitudinal axes of the compartments, a plurality of cylindrical passageways spaced along the channelway, a first set of the passageways extending from a first side of the channelway about an axis transverse to the channelway axis from the channelway through the inboard side of the one compartment into the one compartment, a second set of passageways extending from a second side of the channelway about an axis transverse to the channelway axis from the channelway through the inboard side of the second compartment into the second compartment, the plurality of passageways placing each of the two compartments in communication with the channelway through their inboard sides at a plurality of locations from their open ends substantially to their closed ends.

15. A thin walled collapsible container closed but for an opening from an outlet end,
the outlet end merging with front, rear and two side walls extending longitudinally of the container away from the outlet end to a closed base end, the front wall and rear wall each carrying a respective front and rear valley having side valley walls extending centrally into each front and rear walls toward a respective other of the rear and front wall to a respective front and rear valley valley apex each extending longitudinally of the container, each of the front and rear valley extending continuing from the base end towards the outlet end toward the outlet end, the front and rear valley apex spaced from each other and providing a channelway therebetween along their length from the base end toward the outlet end in all collapsed and uncollapsed conditions of the container, each of the front and rear valley apex comprising a part-cylindrical wall portion about an axis extending longitudinally of the container, each of the part-cylindrical wall portion providing a portion of the channelway longitudinally therein under all collapsed conditions of the container, and, lateral passageways on the interior of the side walls or the valley side walls extending transversely of the channelway and opening at one end into communication with the channelway.
