Claims

We claim:

1. A dispenser comprising:

a dispense assembly having a head assembly; and

a collapsible liner that contains a material to be dispensed, the liner detachably secured to the dispense assembly with the head assembly in fluid communication with an interior of the liner, wherein the material in the liner is dispensed out the liner and through the head assembly.

2. The dispenser of clam 1 , further comprising a diptube operably connected with the dispense assembly and in fluid communication with the material to be dispensed.

3. The dispenser of claim 2, wherein the material to be dispensed is dispensed by pumping the material from the liner, through the diptube, and to the head assembly.

4. The dispenser of claim 1, wherein the dispense assembly is operably coupled with a dispense mechanism, the dispense assembly and dispense mechanism causing dispense of the material to be dispensed by introducing a fluid or gas into the liner, thereby forcing the material in the liner out of the liner and to the head assembly.

5. The dispenser of claim 1, wherein the dispense assembly comprises a dispense mechanism, the dispense mechanism causing dispense of the material to be dispensed by introducing a fluid or gas into the liner, thereby forcing the material in the liner out of the liner and to the head assembly.

6. The dispenser of claim 1, further comprising an overpack that holds the liner and that detachably secures to the dispense assembly.

7. The dispenser of claim 6, wherein the dispense assembly is operably coupled with a dispense mechanism, the dispense assembly and dispense mechanism causing dispense of the material to be dispensed by introducing a fluid or gas into an annular space between the liner and the overpack, thereby causing the liner to collapse and forcing the material in the liner out of the liner and to the head assembly.

8. The dispenser of claim 7, wherein the dispense mechanism is remote from the dispense assembly.

9. The dispenser of claim 6, wherein the dispense assembly comprises a dispense mechanism, the dispense mechanism causing dispense of the material to be dispensed by introducing a fluid or gas between into an annular space between the liner and the overpack, thereby causing the liner to collapse and forcing the material in the liner out of the liner and to the head assembly.

10. The dispenser of claim 9, wherein the head assembly comprises a nozzle in fluid communication with an interior of the liner.

1 1. The dispenser of claim 9, wherein the liner is manufactured from recyclable material,

12. The dispenser of claim 1, wherein the liner comprises a fitment having a closure seal providing secure containment of the materials to be dispensed.

13. The dispenser of claim 12, wherein the closure seal is resealable.

14. The dispenser of claim 12, wherein the fitment comprises mating features for detachably securing the liner to the dispense assembly.

15. The dispenser of claim 1, further comprising a second collapsible liner that contains a different material to be dispensed, the second liner detachably secured to the dispense assembly with the head assembly in fluid communication with the second liner, wherein upon dispense of the materials of the collapsible liner and the second collapsible liner, the materials thereof are mixed.

16. A method for portable dispense of contents of a liner, the method comprising:

detachably connecting a portable dispense assembly, comprising a dispense mechanism and a head assembly, to a collapsible liner with the head assembly in fluid communication with an interior of the liner, the liner containing a material to be dispensed; and

causing the dispense mechanism to introduce a fluid or gas into the liner, thereby forcing the material in the liner out of the liner and to the head assembly.

17. A method for portable dispense of contents of a liner, the method comprising:

detachably connecting a portable dispense assembly, comprising a dispense

mechanism and a head assembly, to an overpack and collapsible liner assembly, with the head assembly in fluid communication with the liner, the liner containing a material to be dispensed; and

causing the dispense mechanism to introduce a fluid or gas into an annular space between the liner and the overpack, thereby causing the liner to collapse and forcing the material in the liner out of the liner and to the head assembly.

18. The method of claim 17, wherein dispense is controlled by a timer-controlled valve.

19. The method of claim 18, wherein dispense is triggered by sensing an external event.

20. A containment system comprising:

a head assembly operably connected with a portable vacuum source;

a liner for receiving a material vacuumed via the head assembly, the liner

detachably secured to the head assembly and in fluid communication with an interior of the liner; and

an oveipack that holds the liner and that detachably secures to the head assembly.

21. The containment system of claim 20, wherein the liner comprises a fitment having a closure seal providing secure containment of the materials received by the liner.

22. The dispenser of claim 21, wherein the closure seal is resealable.

23. The containment system of claim 20, further comprising a neutralizing agent for neutralizing the material received.
