Claims
- 1. A reclosable flexible bag cartridge for containing a fluid comprising:
- a) a nozzle having a substantially flat top surface and a continuous outer portion adjacent said top surface, said nozzle also having an orifice extending therethrough, said orifice having an orifice axis, an outermost end, and a reclosable closure located at said outermost end;
- b) a thermoformed bag having an inside, a sidewall, a bottom, and a flanged end, said bag being open at said flanged end, said flanged end having a flange extending substantially radially outward from said sidewall, said flange being continuous and in a plane except at a nozzle-fitting portion whereat said flange is shaped to wrap around said continuous outer portion of said nozzle, said flange at said nozzle-fitting portion being bonded to said continuous outer portion of said nozzle such that said top surface of said nozzle resides substantially within said plane of said flange; and
- c) a substantially flat piece of film bonded to said flange and to said top surface of said nozzle such that said cartridge is sealed closed by said piece of film, said orifice in said nozzle providing exclusive fluid communication with said inside of said bag.
- 2. The flexible bag cartridge of claim 1 wherein said orifice axis is substantially parallel to said plane of said flange.
- 3. The flexible bag cartridge of claim 1 wherein said sidewall of said bag is thin enough and large enough in diameter that said bag is emptied by inverting said bag.
- 4. The flexible bag cartridge of claim 1 wherein said bag is made of a laminated structure capable of providing barrier properties to said bag.
- 5. The flexible bag cartridge of claim 1 wherein said bag is handled by grasping said nozzle.
- 6. The flexible bag cartridge of claim 1 wherein said reclosable closure is a flip-top cap.
- 7. The flexible bag cartridge of claim 1 wherein a fluid is placed into said bag, said fluid having a level just below said plane of said flange.
- 8. The flexible bag cartridge of claim 1 wherein said thermoformed bag is filled prior to bonding said flat piece of film to said flange of said bag.
- 9. The flexible bag cartridge of claim 1 wherein said bag is filled through an opening different than said orifice in said nozzle.
