Abstract
A collapsible container comprising a flexible bag including a spout having an opening through which liquid is fed into and dispensed from the bag, and a liquid passage member inside of the bag in liquid communication with the spout opening for aiding in the dispensing of liquid from the bag. The liquid passage member is preferably integral with a wall of the bag.
Claims26
A method for producing a disposable flexible bag for use in containing and dispensing a liquid and including a spout having an opening through which the bag is to be filled and emptied, and said bag also including a liquid passage member inside of said bag having at least one elongated liquid channel in liquid flow communication with said spout opening as said bag progressively collapses against said liquid passage member, said method comprising:
- a) providing a pair of flexible bag walls;
- b) providing a spout in one of said bag walls having an opening therethrough and a longitudinal axis substantially perpendicular to said bag wall;
- c) positioning said liquid passage member having said liquid channel inside of said bag walls prior to forming said bag walls into said bag;
- d) positioning said liquid passage member inside of said bag walls such that when said bag walls are formed into said bag having no liquid contained therein, said liquid channel of said liquid passage member will be in liquid flow communication with said spout opening and disposed substantially perpendicular to said longitudinal axis of said spout;
- and
- e) forming said bag walls into said bag with said spout being connected through one of said bag walls.
The method as recited in claim 11 wherein said liquid passage member comprises at least one rib that defines said liquid channel and that prevents said bag walls from blocking liquid flow through said liquid channel when said bag walls have collapsed against said liquid passage member.
A method for producing a disposable, flexible bag for use in containing and dispensing a liquid, comprising:
- a) providing a pair of rectangular bag walls;
- b) heat sealing a spout having a longitudinal axis and a spout opening therethrough to one of said bag walls with the longitudinal axis thereof substantially perpendicular to said bag wall;
- c) positioning a flexible, flat, elongated liquid passage member between said pair of bag walls and adjacent to said spout prior to sealing said bag walls together to form said bag, said liquid passage member having at least one liquid channel therealong in liquid flow communication with said spout opening as said bag empties and progressively collapses against said liquid passage member;
- d) heat sealing said bag walls together to form said bag with said liquid passage member positioned in-between said walls;
- and
- e) securing said liquid passage member in said bag with said channel substantially perpendicular to said longitudinal axis of said spout when said bag is in an unfilled condition.
A disposable, flexible bag for use in containing and dispensing a liquid comprising:
- a) a pair of rectangular bag walls heat sealed together at their peripheries to form a flat rectangular unfilled bag;
- b) a spout having a longitudinal axis and a spout opening therethrough and heat sealed to one of said bag walls with said longitudinal axis substantially perpendicular to said bag wall;
- c) a flexible, flat, elongated liquid passage member positioned inside of said flat bag and having at least one liquid channel formed along at least a portion thereof;
- and
- d) said liquid passage member being secured in said bag and being located in liquid flow communication with said spout opening and with said liquid passage member being disposed substantially perpendicular to said longitudinal axis of said spout when said bag is in an unfilled condition.
