Description

(Field of Invention)
The present invention relates to a sachet having at least two compartments, the sachet comprising a composition comprising a solid component and a liquid component, wherein the solid and liquid components are contained in different compartments.

(Background of the Invention)
Laundry detergent products can now be found on the market in a variety of forms such as solid granule compositions and tablets, or liquid compositions. This allows the consumer to select a detergent product that can be used.

  Certain detergent ingredients currently used in the laundry industry are preferably manufactured and processed in solid form, for example, these components are water insoluble and difficult or expensive to include in liquid detergent compositions. As such, or these materials are preferably transported and supplied in solid form, thus requiring extra processing steps to include them in the liquid detergent composition. Such detergent components include surfactants, so these surfactants require an extra processing step to ensure inclusion in the liquid detergent composition. Also, certain ingredients, such as certain enzyme globules, are formed in granular form for stability reasons and are supplied and processed in solid form.

  Current methods of mixing components that are typically supplied in solid form, such as water insoluble solid components and surfactants, into liquid detergent compositions include the use of emulsifiers and dispersants. However, these liquid detergent compositions contain only a small amount of these solid components. For example, if a dispersant or emulsifier is used, the liquid detergent component may contain only a small amount of certain water insoluble constituents such as aluminosilicates or water insoluble fabric softeners such as clay.

  However, it is desirable to include a water-insoluble solid component, such as a high concentration of a water-insoluble constituent, with a substantial amount of liquid detergent component in the detergent composition. Detergent ingredients, typically transported in solid form, including surfactant-containing granules, can also be mixed with detergent ingredients containing substantial amounts of liquid ingredients without additional expense and difficult processing steps. desirable.

  By using a multi-compartment water-soluble sachet containing at least two separate compartments, the inventors have found that other water-insoluble solid detergent components are difficult and do not require costly manufacturing and processing steps and other liquids. It has been found that it can be included in detergent compositions containing detergent components. The water-insoluble solid detergent component is contained in one compartment of the multi-compartment water-soluble sachet, while the liquid detergent component is contained in the other compartment of the sachet. The detergent composition contained in the multi-compartment water-soluble sachet by such a method can contain a liquid detergent component and a water-insoluble solid detergent component such as a water-insoluble constituent at a high concentration.

  The inventors have made it difficult for detergent ingredients to be transported and supplied to detergent manufacture in normal solid form, such as agglomerates containing surfactants, by using multi-compartment water-soluble sachets containing at least two separate compartments. It has also been found that it can be included in detergent compositions containing substantial amounts of liquid detergent ingredients without the need for costly manufacturing and processing steps. The solid detergent component is contained in one compartment of the multi-compartment water-soluble sachet, while the liquid detergent component is contained in the other compartment of the sachet.

(Detailed description of the invention)
Multi-compartment sachets and their materials The multi-compartment sachets of the present invention are referred to herein as "sachets" and comprise at least two, preferably two compartments.

  The sachets herein are typically closed structures and include a volume space made from the materials described below and separated into at least two compartments. The pouch includes a composition including a liquid component and a solid component. The sachets and their volume space are suitable for holding the composition, for example, any form, shape, and substance that does not release the composition from the sachet before the sachet contacts the water. Can do. The exact implementation will depend, for example, on the type and amount of sachet composition, the number of sachet compartments, and the properties required to hold, protect and transport or release the composition from the sachet. Preferably, the pouch has a spheroid shape.

  The sachet may be sized to conveniently contain either the required operation, for example, a unit dose of the composition herein suitable for a single wash, or only a partial dose, For example, it gives the consumer the flexibility to change the amount used depending on the size of the item to be cleaned and / or the degree of contamination.

  The sachet is manufactured from a water-soluble film containing an internal volume, which is divided into sachet compartments.

  The sachet compartment herein is a closed structure made from a water-soluble film that typically includes a volume space containing the components of the detergent composition. The volume space of the sachet is preferably encompassed by the water-soluble film in such a way that the volume space is separated from the external environment.

  The solid or liquid component contained in the sachet compartment is contained in the compartment volume and is separated from the external environment by a water-soluble film.

  The term “isolated” is used for purposes of the present invention “physically clearly, if the second component is not contained in the same compartment as the compartment containing the first component, the first component contained in the compartment It means “preventing contact with the second component”.

  The term “external environment” means, for the purposes of the present invention, “anything that cannot pass through the material surrounding the compartment and anything that is not contained in the compartment”.

  The compartment is suitable, for example, to hold the solid or liquid component of the composition without releasing components from the compartment before the sachet comes into contact with water. A compartment can have any form or shape, depending on the properties of the substance of the compartment, the characteristics of the component or composition, the purpose of use and the amount of the ingredient or composition.
