Description

Container for wet wipes.

Technical field

The present invention relates to a container that can be sealed that contains a substrate that incorporates a composition. The composition comprises a cleaning composition and / or antimicrobial The substrate together with the composition can be used to clean and / or disinfect animated surfaces (e.g., skin human, mouth) and inanimate surfaces including, but not limiting form, hard surfaces such as walls, tiles, tables, glass, bathroom surfaces, kitchen surfaces, dishes as well like fabrics, clothes and carpets.

Background of the invention

Cleaning and / or disinfectant compositions are well known in the art. The compositions are available in many forms, for example, as liquids, sprays and more recently as wet wipes.
you give.

Wet wipes provide a way Easy and quick to clean and / or disinfect any type of surfaces. In fact, wet wipes can be used in a variety of applications both domestic and industrial. From Typically, wet wipes are used to clean and / or disinfect animated surfaces (e.g., human skin, mouth) and inanimate surfaces, including, but not limited to, hard surfaces such as walls, tiles, tables, glass, surfaces of bathrooms, kitchen surfaces, dishes, as well as fabrics, clothes and carpets

In general, said wet wipes consist practically in a substrate that incorporates a composition. From done, the composition used for wet wipes cleaners have to present at least some advantages over The cleaning capacity. Wet disinfectant wipes can be similar to wet wipes, but the composition incorporated therein further comprise a disinfectant material It is generally recognized that a material Disinfectant of this type reduces in large proportion or even eliminates microorganisms, e.g. eg, bacteria, which exist on a surface. In other more preferred disinfectant compositions the residual antimicrobial advantages are released over time (it is say, 12, 24 h) since the application is not clarified.

Wet wipes that consist of a substrate incorporating a composition are already known in the technique. For example, application WO 89/05114 describes wipes disposables for hard surface cleaning that are impregnated with a liquid composition

However, the advantages over capacity cleaner and / or disinfectant of wet wipes currently used can be further improved. In addition, to the advantages of cleaning and / or disinfectant capacity, other key advantages Wanted include reducing the presence of waste during The drying of the composition and improvement of brightness. These benefits may in some cases interfere with each other and this is the constant effort of the manufacturer to provide a better cleaning and / or disinfectant capacity without adversely affecting the residue level remaining and / or brightness.

In addition, an inconvenience associated with the wipes currently used wet is that the liquid that includes the composition incorporated on the substrate can evaporate partially or even completely during storage, what which results in drying of the wipe. The drying of the wipe significantly reduces cleaning capacity and / or disinfectant originally provided by wet wipes. Thus, wet wipes can be packaged in a container that you can close, for example, a plastic box, as described in the applicant's codependent patent application EP 99870131.2. However, evaporation of the composition may still take place even if a container that can be closed is used, This may, for example, be due to insufficient sealing or complete absence of the seal provided by said containers and / or insufficient closing mechanisms of said containers. So, evaporation reduction or inhibition can be further improved of the composition incorporated on a substrate.

It is therefore an objective of the present invention provide a wet wipe cleaner and / or disinfectant that presents better cleaning, shine, inhibition of soaps and less waste during drying and also, in disinfectant embodiments, better efficiency disinfectant and at least maintaining, although preferably improving, the advantage of residual disinfection.

It is another objective of the present invention provide a wet wipe cleaner and / or disinfectant in the that the evaporation of the composition incorporated on the substrate It is reduced or even basically inhibited.

These objectives are met by the recipient that can be sealed that contains a substrate that incorporates a composition comprising a multiple surfactant system, according to the present invention

As described above, the sugar units may be additionally alkoxylated before or after the reaction with the fatty alcohols. Said alkyl polyglycosides are described in detail for example in the application WO 86/05199. Industrial alkyl polyglucosides are generally non-molecularly uniform products, but represent mixtures of alkyl groups and mixtures of monosaccharides and different oligosaccharides.
