Problems solved by technology

In either case, premature rupture of a water-soluble unit-dose product can adversely affect the dosing experience, as the contents of the ruptured unit-dose product can contaminate other unbroken unit-dose product products
As a result, users may find the dosing experience 'messy' and inconvenient
[0007] Additionally, seal failure may occur during the unit dose product manufacturing process
[0008] This failure results in wasted resources and time due to the need to discard the ruptured bag

Embodiment

[0161] The following unit dose articles were prepared according to the protocol described herein and the unit dose articles were tested for seal strength. The comparative unit dose articles outside the scope of the invention were made from a single film type, whereas the example unit dose articles according to the invention were made according to the invention from two different films with different water capacity values.

[0162]A multi-compartment water soluble unit dose article having a footprint of 41 mm x 43 mm, a cavity depth of 20.1 mm and a cavity volume of 25 ml was prepared by thermo / vacuum forming. For the dual film example unit dose articles, Film A and Film C were deformed under vacuum while Film B and Film D were respectively used as occlusive films. The standard cleanser composition of Fairynon-Bio in the bottom compartment of the 3 in 1 water soluble unit dose product product as marketed in the UK in January 2016 was enclosed in these unit dose products.

Abstract

The present invention relates to the use of a first water-soluble film and a second water-soluble film to make a unit dose article and the use of said unit dose article.

Description

[0001] Cross References to Related Applications [0002] The benefit of U.S. Provisional Patent Application No. 62 / 349,639, filed June 13, 2016, is hereby claimed under 35 U.S.C. § 119(e), the disclosure of which is incorporated herein by reference. [0003] unit dose product technical field [0004] The present invention relates to the use of a first water-soluble film and a second water-soluble film for the preparation of a unit dose product and the use of said unit dose product. Background technique [0005] Water-soluble cleanser unit dose articles are preferred by users because they are a convenient, efficient and clean way of dosing a composition, such as a cleanser during a laundering process. The water soluble unit dosage form means that the user does not have to measure doses himself or encounter accidental spills of the composition which some users find messy and inconvenient. [0006] However, such water-soluble unit dose products may suffer from premature ruptu...
