[0192] Table 1 is a non-limiting example of compositions suitable for dosing according to the methods and systems described herein. The composition is dosed into a chamber comprising a web made of a water soluble film according to those disclosed in U.S. Patent Application 2011 / 0188784A1, and comprising a M8630 water soluble film (available from MonoSol LLC (Merrillville, Indiana). , USA)) on the web.

Abstract
The present disclosure relates to methods, and corresponding systems, for filling cavities (110, 111, 112) with a composition (300) into said cavities (110, 111, 112) of a web (100) that continuously moves in a machine direction (MD), said method comprising the steps of: providing a web (100) comprising a water-soluble film, typically disposed on a continuously moveable surface (116) in a machine direction (MD), said web (100) comprising at least two thermoformable cavities (110, 111, 112) aligned in said machine direction (MD); providing a filling apparatus (200) comprising at least two nozzles (210, 211, 212) aligned in said machine direction (MD), positioned to dispense a household care composition (300), into said cavities (210, 211, 212); dispensing said composition (300) from said at least two nozzles (210, 211, 212) into said at least two cavities (110, 111, 112) while said at least two nozzles (210, 211, 212) move from a first position (FP) to a second position (SP); and returning said at least two nozzles (210, 211, 212) to said first position (FP).
Description
technical field [0001] The present disclosure relates to methods and systems for dispensing compositions. Background technique [0002] Unit dose articles filled with compositions, particularly household care compositions such as laundry detergents, are becoming increasingly popular with consumers. Generally, such articles are made in part by forming cavities in a web, such as a water-soluble film web, filling the cavities with the composition, and then forming a complete unit dose article, such as by sealing and compartmentalizing the article. [0003] Accordingly, manufacturers are constantly seeking ways to improve the speed and efficiency of the process of filling cavities with compositions. The web is typically placed on a moving surface and the cavities are filled as it moves past a filling device, such as a filling nozzle. A start-stop fill process in which the cavity stops below the nozzle as it is filled with the composition keeps the nozzle stationary but slows d...
