Abstract

Provided are flexible containers for holding a concentrate, the containers comprising: a flexible body holding the concentrate, a spout, a filter element disposed in the spout, the filter element comprising a filter and an attachment element configured to attach to a water source. Also provided are methods of reconstituting concentrated products using the flexible containers.

First claim

What is claimed is:

1. A method of reconstituting a concentrated product comprising:
(a) providing a flexible container holding a concentrate, wherein said concentrate is a concentrate of a consumer product selected from the group consisting of lotions, soaps, shampoos, conditioners, body washes, facial cleansers, moisturizers, astringents, exfoliation products, microdermabrasion and peel products, skin rejuvenation products, anti-aging products, and UV protection products, wherein said flexible container comprises: (1) a flexible body holding said concentrate, (2) a spout, (3) a filter element disposed in said spout, wherein said filter element comprises a filter, wherein said filter is selected from the group consisting of nano-filter media; nano-fibers on micro-glass fiber carries; carbon nano-tubes; and mixtures thereof; and (4) an attachment element configured to attach to a water source;
(b) attaching a water source to the attachment element of the flexible container; and
(c) forcing water through the filter element of the container and into the container to form a reconstituted concentrate.

2. The method of claim 1 wherein said flexible container is in the form of a pouch.

3. The method of claim 2 wherein said water source is a hand held water bottle and said forcing step comprises squeezing said water bottle by hand to push water through the filter element and into said flexible container to reconstitute the concentrate.

4. The method of claim 3 wherein said flexible container is filled within a period of about five minutes or less.

5. The method of claim 4 wherein said container comprises a visible fill indicator and said forcing step comprises forcing sufficient water through the filter element such that the visible fill indicator indicates that the container is full.

6. The method of claim 1 further comprising the step of removing the filter element from said spout to dispense the reconstituted concentrate though said spout.

7. The method of claim 6 wherein said filter element remains attached to said water source when said filter element is removed from said spout.

8. The method of claim 1 wherein said flexible container comprises a second spout and said method further comprises the step of dispensing the reconstituted concentrate through said second spout.

9. The method of claim 1 wherein said concentrate is substantially free of preservatives.

10. The method of claim 1 wherein said forcing step comprises forcing water through said filter at a flow rate of about 10 ml/(min*cm 2 ) or greater.

11. The method of claim 10 wherein said forcing step comprises forcing water through said filter at a flow rate of about 20 ml/(min*cm 2 ) or greater.

12. The method of claim 7 further comprising the step of forcing water from the water source through the filter element removed from the spout to produce filtered water outside of said flexible container.

13. The method of claim 6 wherein said removed filter element is removed from the spout and the water source, optionally cleaned, and then attached to the same or a different water source.

14. The method of claim 12 wherein after said removed filter element is attached to the same or a different water source, water is forced therethrough to produce filtered water.
