Article comprising a water soluble bag containing a multiple use amount of a pelletized functional material and methods of its use
First Claim
1. A method of dispensing multiple volumes of an aqueous solution of a wash chemical from a dispenser comprising the steps of:
- (a) depositing a sealed water soluble article containing a wash chemical into said dispenser;
(b) repeatedly directing water onto an article contained in said dispenser in response to a concentration monitoring device in order to form a concentrate; and
(c) repeatedly directing said concentrate to a use location wherein said article comprises(i) a sealed water soluble container made of a flexible film, and(ii) a multiple use amount of a pelletized water soluble or dispersible was chemical comprising a silicate, an alkaline metal hydroxide or mixtures thereof contained within said sealed water soluble container made of a flexible film.

Abstract
An article comprising a water soluble container containing a multiple use amount of a pelletized functional composition such as a fabric treatment composition, a warewashing composition, a laundry composition, a pot and pan presoak composition, a silverware presoak composition, a floor cleaner composition, a rinse additive composition, a disinfectant composition, a sanitizer composition, a general purpose cleaner composition, etc. The article may be optionally enclosed in a water impervious outerwrap. A method for using the article by placing the article inside a dispenser wherein the article is contacted with water having a sufficient temperature and pressure to dissolve the water soluble bag and the pelletized functional material contained therein in order to form a solution.

15. A method for delivering an aqueous alkaline wash chemical, the method comprising:
-
(a) removing a water impervious outerwrap from an article comprising; (i) the water impervious outerwrap; (ii) a container comprising a sealed, water-soluble film; and (iii) a multiple use amount of a pelletized, water soluble or dispersible wash chemical comprising a silicate, an alkali metal hydroxide or mixtures thereof contained within the container; (b) placing the article from which the outerwrap has been removed into a dispensing device; (c) directing water onto the article contained within the dispenser to open and to dissolve the film and to form a supply of an alkaline wash concentrate; and (d) directing the supply of alkaline wash concentrate from the dispenser. - View Dependent Claims (16, 17)

18. A method for delivering an aqueous alkaline wash chemical, the method comprising:
-
(a) selecting an article comprising; (i) a moisture impervious barrier material; (ii) a container comprising a sealed, water-soluble film; and (iii) a multiple use amount of a pelletized, water soluble or dispersible wash chemical comprising a silicate, an alkali metal hydroxide or mixtures thereof contained within the container wherein the moisture impervious barrier material sealingly isolates the container from atmospheric moisture; (b) removing the moisture impervious barrier material from the container; (c) placing the article into a dispensing device; (d) directing water onto the article contained within the dispenser to open and to dissolve the film and to form a supply of an alkaline wash concentrate; and (e) directing the supply of alkaline wash concentrate from the dispenser.
