Description

Detailed Description of the Invention

FIELD OF THE INVENTION The present invention relates to sachets having at least two compartments, the sachets comprising a composition comprising a solid component and a liquid component, the solid and liquid components being contained in different compartments.

BACKGROUND OF THE INVENTION Laundry detergent products are currently available on the market in various forms such as solid granular compositions and tablets, or liquid compositions. This allows the consumer to choose which detergent products to use.

Certain detergent ingredients currently used in the laundry industry are preferably manufactured and processed in solid form, for example, these ingredients are water insoluble and are included in liquid detergent compositions. Because of the difficulty or expense, or because these materials are shipped and supplied, preferably in solid form, they require extra processing steps to be included in a liquid detergent composition. Such detergent ingredients include surfactants, which require extra processing steps to ensure their inclusion in a liquid detergent composition. Also, some components, such as certain enzyme globules, are formed in granular form for stability reasons and are supplied and processed in solid form.

Current methods of incorporating 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 small amounts of these solid ingredients. For example, if a dispersant or emulsifier is used, the liquid detergent component may include only small amounts of certain water-insoluble constituents such as aluminosilicates or water-insoluble fabric softeners such as clay.

However, it is desirable to include a substantial amount of liquid detergent ingredients in the detergent composition along with a high concentration of water-insoluble solid ingredients such as water-insoluble constituents. It is also possible to mix detergent ingredients, which are typically shipped in solid form, including surfactant-containing granules, into detergent ingredients that contain substantial amounts of liquid ingredients without extra expense and difficult processing steps. desirable.

By using multi-compartment water-soluble sachets containing at least two separate compartments, the inventors have found that water-insoluble solid detergent ingredients do not require difficult and costly manufacturing and processing steps. It has been found that it can be incorporated into detergent compositions that include other liquid detergent ingredients. 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 high concentration of a water-insoluble solid detergent component such as a water-insoluble constituent together with the liquid detergent component.

We use a multi-compartment water-soluble pouch containing at least two separate compartments to deliver and deliver detergent ingredients to detergent manufacture in a normally solid form, such as aggregates containing surfactants. It has also been found that can be incorporated into detergent compositions containing substantial amounts of liquid detergent ingredients without the need for difficult and costly manufacturing and processing steps. The solid detergent component is contained in one compartment of a multi-compartment water-soluble pouch, while the liquid detergent component is contained in the other compartments of the pouch.

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, and preferably two compartments.

The pouches herein are typically of closed construction and include a volumetric space made of the materials described below and separated into at least two compartments. The pouch contains a composition that includes a liquid component and a solid component. The pouches and their volume are of any form, shape and substance suitable for holding the composition, for example the composition is not released from the pouch before it comes into contact with water. You can Exact execution is
For example, the type and amount of the sachet composition, the number of compartments in the sachet, holding the composition from the sachet,
It depends on the properties required to protect and carry or release. Preferably, the pouch has a spheroidal shape.

The pouch is sized to conveniently contain either the unit dose of the composition herein suitable for the required operation, eg, a single wash, or only a partial dose. It may give the consumer the flexibility to vary the amount used, for example depending on the size of the item to be washed and / or the degree of soiling.

The pouch is made from a water-soluble film that contains an internal volume, which internal volume is divided into compartments of the pouch.

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

The solid component or liquid component contained in the compartment of the sachet is contained in the volume space of the compartment,
Separated from the external environment by a water-soluble film.

In addition, one or more detergent compositions other than the detergent composition contained in the multi-compartment pouch can be used during the washing process, and the detergent composition contained in the multi-compartment pouch can be used as a pre-treatment during the washing process, It may be used as a treatment, a post treatment or a combination thereof.

Example I A piece of plastic is placed in a mold to act as a temporary bottom.
The mold is cylindrical and has a diameter of 45 mm and a depth of 25 mm. A 1 mm thick rubber is present around the edges of the mold. The mold has several holes in the mold material for applying a vacuum. The depth of the mold with the installed temporary bottom is 12 mm. A piece of Chris-Craft M-8630 film is placed on top of the mold and secured there. A vacuum is applied to pull the film into the mold, pulling it snugly over the mold as well as the interior surface of the temporary bottom. Liquid component of detergent composition 5m
Pour l into the mold. Then, a second piece of Chris-Craft M-8630 film was placed on top of the mold with the liquid components and an annular piece of flat metal with an internal diameter of 46 mm was applied to the annular part at the edge of the mold. The first piece of film is sealed by heating the metal under moderate pressure on rubber, thereby heat sealing the two pieces of film to form a compartment containing the liquid component. The metal ring is typically heated at a temperature of 135 ° C to 150 ° C and applied for up to 5 seconds.

The compartment containing the liquid compartment is removed from the mold and the plastic piece that acts as a temporary bottom is removed from the mold. A third piece of Chris-Craft M-8630 film is placed on top of the mold and secured there. A vacuum is applied to pull the film into the mold so that it is flush with the inner surface of the mold. Pour 40 g of the solid ingredients of the detergent composition into a mold. Next, a compartment containing the liquid component is placed on top of the mold with the solid component, an annular piece of flat metal with an internal diameter of 46 mm is applied and the metal is heated under moderate pressure in the annular rubber at the edge of the mold. Thereby sealing the third layer of film, thereby heat sealing the piece of film to form a pouch containing two compartments, wherein the first compartment contains the liquid component of the detergent composition and the second compartment is It includes the solid components of the detergent composition. The metal ring is typically heated at a temperature of 135 ° C to 150 ° C and applied for up to 5 seconds.
