A washing device (1) has in a washing piece receptacle (2), which is closed on at least one side with a sponge material (5) having sponge material (5) to the outside, a washing piece (3), which at least as a foaming substance and as the main component a synthetic surfactant.

Description

The invention relates to a washing device with a preferably closed to the outside of the washing piece receptacle and with a washing piece used in the washing piece, wherein the washing piece receptacle is closed on at least one side with a pore-containing sponge material to the outside.

Such washing devices are known in different embodiments and are used for example for body cleansing. The purpose of these washing devices is, at the same time as the mechanical cleaning process in which the washing device is rubbed over a body part, also to deliver a detergent substance, preferably with foaming, to the body.

The object of the invention is to improve the performance characteristics of the previously known from the prior art washing devices of the type mentioned.

This object is achieved in the washing device defined above by the means and features of claim 1 and in particular characterized in that the washing piece contains as foaming substance and as the main component at least one synthetic surfactant.

It has been found that in the case of washing pieces which contain at least one synthetic surfactant as the foaming substance and as the main constituent, foaming takes place already by mere contact of the washing piece with water and air occurs without friction being required for foaming.

In contrast, for example, in soaps that are typically used, it is necessary to froth the soap by friction between the soap and a surface, such as a body part to be cleaned, or a sponge or washcloth. However, this can be disadvantageous because the foaming of a soap is relatively difficult to set in motion.

When using the washing device according to the invention, there is now the advantage that a mere ingress of water through the pores of the sponge material into the wash piece receptacle and the associated contact of the wash piece with water and air suffice to develop the foam which is pleasant for body cleansing. This foam, which thus arises within the washing device in the washing piece receptacle, can be conveyed through the pores of the foam material, through which water and air have previously penetrated into the washing piece receptacle, and is then available for a washing or cleaning process.

If the washing piece is captively trapped in its use position within the washing piece receptacle, it can not fall out of the washing device even if it loses volume in the course of use of the washing device and the progressive consumption of the washing piece. An exchange of the washing piece can be prevented in this way.

It is particularly favorable if the washing piece consists of at least 50%, preferably at least 80%, particularly preferably at least 95%, of the at least one synthetic surfactant. If the washing piece only from the at least one synthetic surfactant or only synthetic surfactants it can also be called a syndet.

In a washing device according to the invention, which is suitable for a particularly skin-friendly cleaning, the washing piece can be formed soap-free. Soap-free cleaning of the skin is to be preferred in particular for sensitive persons. Soap-free can be characterized, for example, by the fact that no alkali metal salts of carboxylic acids are present.

Furthermore, it is possible that the washing piece is designed as a Combar. As Combars are referred to such washes containing both soap and Syndetanteile.

Thus, it is possible to provide a washing device in which the washing piece of the washing device according to the invention in addition to a Syndetanteil also has a soap content with a soap.

Furthermore, the syndet component and the soap component may be inseparably mixed. Thus, a homogeneous distribution of Syndetanteils in the wash piece can be achieved.

In one embodiment of the invention, it may be provided that the pores of the sponge material are substantially free of surfactant prior to use of the washing device, for example in relation to a total length of a pore or the pores, or completely.

For ventilation and / or humidification of the washing piece from the outside, it is advantageous if the pores are air and / or water permeable. In this way, it is possible that a necessary for the wetting of the washing piece and for the foaming of the wash-forming substances necessary amount Water and air can pass through the pores to the wash piece. In addition, it is possible that the foam formed in the Waschstückaufnahme can escape through the pores again.

In an advantageous embodiment of the washing device, the washing piece can be surrounded on all sides with sponge material.

Furthermore, it is possible for the washing device to have two halves which can be connected to one another and which enclose the washing piece and / or the washing piece receptacle in the connected position of use. In this case, one of the halves or both halves can at least partially consist of the sponge material.

It may also be expedient if one half of the washing device has, on its side facing the other half in the use position, a recess forming the washing piece receptacle into which the washing piece is inserted in the position of use.

But it is also possible that both halves of the washing device each have a recess on their side facing the other half in the use position. These two recesses can then together in the connected position of use of the two halves form the Waschstückaufnahme, in which the washing piece is inserted in the use position. Thus, a tension-free connection of the two halves are made possible, in which a joint between the two halves is little or no load. This can promote the durability of the connection and extend the useful life of the washing device.

For connecting the two halves of the washing device can be provided that the two halves of the washing device, in particular after the introduction of the washing piece into the washing piece receptacle, are glued together. It may be particularly advantageous if this is done with a label-free adhesive.

Label-free adhesives or adhesives are those adhesives or adhesives that are harmless to health due to their composition and therefore freely available. Such adhesives or adhesives are therefore particularly suitable for use in the washing device according to the invention, since they can come into contact with skin when used as intended, ie could be referred to as a cosmetic product. In this way, washing devices according to the invention can be provided, which are also suitable for use in infants or babies, who experience has a more sensitive skin than adult persons.

It can also be advantageous if the washing piece is prefabricated with suitable format for insertion into the washing piece receptacle, in particular is pre-cut. In particular, the punching of the wash piece from a blank can be regarded as a particularly simple and therefore efficient way of manufacturing. Compared to the previously known from the prior art washing devices in which the detergent substance is injected or inserted into a cavity and / or pores of the sponge material of these devices, the washing piece can be inserted in the washing device according to the invention in its pre-punched format in the washing piece receptacle , This results in the significant improvement that the fixed shape of the wash piece can lead to a significantly longer shelf life of the wash and thus the washing device itself, since the surface is smaller by the punched shape and the water so on a smaller area at the same time with the wash responding. At an injection of washing active In contrast, substances in the pores would not form a uniform shape of a lump, and the water would react simultaneously at all points, thus leading to a very rapid consumption of the washing-active substances and / or of the washing piece.

In particular, when the washing device has two halves which are completely glued together at their contact surfaces, there is no possibility to refill the washing device with a syndethaltigen piece of laundry, should the used in the production of the washing device washup be used up.

When the washing piece has a smooth surface, on the one hand, it is possible to dissolve a sufficient amount of synthetic surfactant for a good effect of the washing device by wetting or flushing the surface of the washing piece with water from the washing piece and, on the other hand, to limit the amount of dispensing of synthetic surfactant to achieve a sufficient period of use of the washing device, within which the detergent-active substance can be delivered with foaming.

The washing device may be particularly suitable for use with sensitive persons and / or allergy sufferers if the at least one synthetic surfactant is disodium lauryl sulfosuccinate. The wash piece may also contain anionic and / or cationic substances, for example sulfoacetates, in particular disodium laureth sulfosuccinates.

For a comfortable handling and also storage of the washing device according to the invention, this can have at least one suspension device. Such a suspension device can be designed in particular as a cord, hook, eyelet and / or loop.

The sponge material of the washing device may consist of synthetic sponge, foam and / or natural sponge. A mixture of the aforementioned materials is of course also conceivable. The sponge material can be punched or cut as desired to give the washing device any shape. As a result, the washing device and in particular the sponge material of the washing device can be given, for example, an animal form or any fantasy shape.

Suitable artificial sponges or foams are, for example, foams of polyethylene (PE), polyolefin (PO), so-called hydro-foam, ether foams and / or ester foams.

Various variants of the washing device according to the invention are conceivable. Thus it can be provided in a washing device that the washing device, in particular a half of the washing device, a handle and / or a glove and / or a cloth and / or a towel and / or a washing brush and / or arranged or formed on a washing brush is.

Thus, the particularly advantageous mode of action of the washing device according to the invention can be combined with other, effective cleaning effective functions.

Furthermore, it is possible that the washing piece also contains at least one washing-active substance which contains no surfactants. Such detergent substances may be, for example, polish agents and / or a solid rinse.
