Description

Territory of invention

These The invention relates to water-soluble Bag.

Background of the invention

The Detergent industry has tried to develop ways that the contact between incompatible Detergent ingredients during the manufacture, transport and storage of detergent products to a minimum before adding to the wash cycle.

One such way is the development of a water-soluble multi-chamber bag for detergents. Incompatible Detergent ingredients become different in this bag Chambers enclosed in such a way that they are with each other not in touch come up to the bag while the washing process in the water dissolves or it disintegrates.

Examples these multi-chamber bags are disclosed in US-A 4,973,416 and US-A 5,224,601 described. The use of chambers, which are different Detergent ingredients are designed to be with storage incompatible Detergent ingredients overcome problems because these ingredients, after being in separate compartments, not in storage during storage Come in contact.

The Inventors have found that there is a risk that detergent leak out of multi-chamber bags and have additionally found that detergent ingredients even more likely from the seals of a multi-chamber bag leak, especially if the chambers because of the poor seal strength at the same time to be sealed. The risk of leakage is greater when a chamber has a liquid includes.

The Inventors have further found that when the chambers are at the same time be sealed, a procedure which requires that the unsealed chambers in fairly close proximity, There is a risk that the ingredients during the sealing process due to the lack of a seal to prevent the exchange of components between the two chambers during the early stages of the sealing process, from an unsealed chamber in the other run. This is all the more true if one or more Ingredients liquid are.

The Inventors herein have found that when using a prior sealed water-soluble Chamber for closing a non-sealed chamber, forming a water-soluble multi-chamber bag, the water-soluble Multi-chamber bag is more stable and a lower risk of leakage the components from the seals of the bag during the Manufacture and storage of the bag is. This is due to the multiple closure used in the above closure method is formed. This is especially true if the before sealed water-soluble Chamber a liquid includes.

B. the release of the composition the bag before the touch of the bag with water. The exact execution will on the type and amount of the composition in the bag, the number of Chambers in the bag, the required properties of the bag for Restraint, for the protection and release or release of the compositions depend.

Of the Bag can be of such a size that he can comfortably take either a single dose of the required Process, such as B. a laundry, suitable composition herein, or only a proportionate one Dose to allow the consumer greater flexibility in changing the quantity as dependent, for example of the size and / or the degree of contamination of the laundry load.

Of the Bag is made of a water-soluble Produced film, wherein the film includes an inner volume, and wherein the internal volume is divided into chambers. The exact procedure for the preparation of the bag is described in more detail hereinafter.

The Chamber of the bag has a closed structure, which made of materials described herein, and a volume space includes, which comprises the components. The volume space is preferably from a water-soluble Foil injected in such a way that the volume space from the outside environment is separated.

Of the Term "separated" means for the purposes this invention "physically separated, in that a first, enclosed by a chamber Component of the touch is prevented with a second ingredient when the second ingredient is not enclosed by the same chamber, which is the first Part encloses ".

Of the Expression "outer environment" means for the purposes this invention "everything, what the water-soluble Foil which encloses the chamber and not from the chamber is enclosed, can not penetrate ".
