Description

FIELD OF THE INVENTION

[0001] Consumer product comprising a package and at least one water-soluble unit dose article.

BACKGROUND OF THE INVENTION

[0002] Water-soluble unit dose articles are liked by consumers due to their convenience and ease of use. Water-soluble unit dose articles comprise a water-soluble film shaped to form at least one internal compartment which houses a single use dose of a detergent. Upon addition of the water-soluble unit dose article to water, the water-soluble film dissolves and/or disintegrates releasing the detergent into the surrounding water to produce a wash liquor.

[0003] Such water-soluble unit dose articles are generally stored and transported in rigid plastic containers or plastic bags. However, such rigid or flexible plastic containers may be undesirable for various reasons, including concerns for environmental sustainability and lack of consumer appeal.

[0004] Therefore, there is a need for a consumer product comprising a package, that protects the water-s0luble unit dose articles and is environmentally friendly.

BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The embodiments set forth in the drawings are illustrative in nature and not intended to limit the invention defined by the claims. The following detailed description of the illustrative embodiments can be understood when read in conjunction with the following drawings, and in which:
Figure 1 illustrates an embodiment of the opening mechanism according to the present disclosure. Particularly, the opening mechanism as shown is a perforation pattern which comprises 6 lines of v shape.

[0051] The detergent composition may be a laundry detergent composition, an automatic dishwashing composition, a hard surface cleaning composition, or a combination thereof. The detergent composition is a perfumed detergent composition. By `perfumed detergent composition' we mean that free perfume has been added to the detergent composition. By `free perfume' we herein mean perfume compounds are added directly to the detergent composition and are not present on encapsulates or on carrier materials. The composition might also comprise secondary perfume sources such as perfume capsule and/or pro-perfume e.g. perfume bound to a carrier material technology. The detergent composition may comprise a solid, a liquid or a mixture thereof. The term liquid includes a gel, a solution, a dispersion, a paste, or a mixture thereof.

[0052] The solid may be a powder. By powder we herein mean the detergent composition may comprise solid particulates or may be a single homogenous solid. Preferably, the powder detergent composition comprises particles. This means the powder detergent composition comprises individual solid particles as opposed to the solid being a single homogenous solid. The particles may be free-flowing or may be compacted, preferably free-flowing.

Alternatively the non-soap anionic surfactant system may be free of alkoxylated alkyl sulphate, more preferably the non-soap anionic surfactant consists of linear alkylbenzene sulphonate anionic surfactant.

[0058] Exemplary linear alkylbenzene sulphonates are C₁₀-C₁₆ alkyl benzene sulfonic acids, or C₁₁-C₁₄ alkyl benzene sulfonic acids. By `linear', we herein mean the alkyl group is linear. Alkyl benzene sulfonates are well known in the art.

[0059] The alkyl sulphate anionic surfactant may comprise alkoxylated alkyl sulphate or nonalkoxylated alkyl sulphate or a mixture thereof. The alkoxylated alkyl sulphate anionic surfactant preferably is an ethoxylated alkyl sulphate anionic surfactant.

[0069] The laundry detergent composition comprises a perfume, more specifically a free perfume. Those skilled in the art will know of possible free perfumes to be formulated inside a liquid laundry detergent composition to be formulated inside a water-soluble unit dose article. These free perfume compositions are composed of a broad range of individual perfume raw materials which are carefully balanced to create a desired perfumed character, perfume deposition and perfume longevity profile, and this across the different stages of the wash and wear process, e.g. upon dosing of the detergent composition, upon removal of the wet fabrics from the laundry washing machine or upon hand-washing, upon line-drying or at the end of tumble drying process, upon storage of the fabrics in consumers' wardrobe and upon wearing the fabrics. This balanced selection of individual perfume materials typically considers, in addition to the perfume character of an individual raw material, also its polarity, volatility and perceived intensity. The detergent composition preferably comprises between 0.01 and 10%, preferably between 0.1% and 5%, more preferably between 0.5% and 3% of free perfume. In addition to free perfume also a secondary source of perfume can be present, more particularly the detergent composition might also comprise encapsulated perfumes or pro-perfume technologies, or a mixture thereof. Preferably, the laundry detergent composition comprises an adjunct ingredient selected from the group comprising builders including enzymes, citrate, bleach, bleach catalyst, dye, hueing dye, brightener, cleaning polymers including alkoxylated polyamines and polyethyleneimines, soil release polymer, surfactant, solvent, dye transfer inhibitors, chelant, encapsulated perfume, polycarboxylates, structurant, pH trimming agents, and mixtures thereof.

[0071] When liquid, the laundry detergent composition may be Newtonian or non-Newtonian. Preferably, the liquid laundry detergent composition is non-Newtonian. Without wishing to be bound by theory, a non-Newtonian liquid has properties that differ from those of a Newtonian liquid, more specifically, the viscosity of non-Newtonian liquids is dependent on shear rate, while a Newtonian liquid has a constant viscosity independent of the applied shear rate. The decreased viscosity upon shear application for non-Newtonian liquids is thought to further facilitate liquid detergent dissolution. The liquid laundry detergent composition described herein can have any suitable viscosity depending on factors such as formulated ingredients and purpose of the composition.

[0072] Those skilled in the art will know how to formulate and make a suitable detergent composition using known knowledge and techniques.
