Abstract

A laminate comprising a honeycomb layer (3), the lower holes of which are closed through base layer (2), and the upper holes through top layer (4) with formation of honeycomb chambers.

Description

The invention relates to a layer material according to the preamble of claim 1.

Layer materials are in different compositions tongues known. In this case, they are preferably layered Materials such as B. foils with different properties combined for special effects the exchange of air and vapors. The known layered materials in use, white However, it does not have a storage effect with which it for example, it would be possible to add certain substances or substances to transport the composition specifically to a place of action ren or hand in there.

The invention is therefore based on the object Offering layered material that multifunctional own associated with a metered delivery of active ingredient fen. If necessary, this layer material also have pressure-damping properties.

The problem is solved with the characteristic part of claim 1.

Advantageous further developments are in the subclaims given.  

The layer material according to the invention consists of a Wa layer, the lower honeycomb openings through a base layer and the upper honeycomb openings through a deck layer closed to form honeycomb chambers are. The layer material according to the invention enables as required continuously or specifically z. B. Liquid to deliver from or into individual honeycomb chambers take. The honeycomb shape is preferably selected here, to achieve better pressure resistance. Indeed are other forms of training these chambers think bar. The individual layers of the layer according to the invention materials are arranged so that they are layered over lie to each other. Depending on the effect to be achieved and the materials used can build the film be strong or much thicker.

It is intended to combine active ingredients in the honeycomb chambers settlements, if necessary connected with fillers. The honeycomb chambers consist of an elastic special membrane bran. These adapt to the volume of the filling material, which ensures constant contact with the side walls and a Vapor or liquid exchange between the chambers is made possible. Due to this material arrangement, a Prevents drying of individual honeycomb chambers and a bes distribution when ingesting or dispensing liquid guaranteed. An exchange of solids between the Honeycomb chambers are not possible or only possible to a small extent Lich.

One advantage of the honeycomb system is that that even drug delivery or fluid recording on the entire surface is made possible. Also then when only certain areas of the surface ge be pressed or used. The chambers adapt to the Vo lumen of the filling material and enables a steam or Liquid exchange between the chambers. So will  enables an even distribution of the liquids, even if only parts of the surface are used become.

The active ingredient-storing filler consists, for. B. from egg swellable polysaccharide or a natural, semi-synthetic or synthetic polymer. Products with these properties are u. a. from the company BASF at the trade name HySorb. After the inclusion of These materials swell in a short time by a factor of 8 to 125.

The layer material according to the invention can be used industrially as Be manufactured by the meter. In a fusion welding process drive, whereby the side edges are firmly connected different shapes can be produced become. The storage material is e.g. B. already as granules embedded in the yard goods. The amount is to be measured that even after adding the active ingredient, taking into account swelling effect of the granules, sufficient space is in the chambers.

It is possible to change the chambers after consumption of the active ingredient to fog up again with an active ingredient. But it is questionable whether this increased workload is worthwhile. By inexpensive mass production it is more economical to replace the used product with a new one.

The layer material according to the invention is suitable for fol fields of application:  

Decontamination and disinfection of surfaces

The most important route of transmission of pathogens of all Kind are the hands; approx. 80% of all infections are diagnosed transferred this way. Decontamination and disinfection on or even a reduction in pathogens On frequently used areas, it is desirable to use this over to interrupt or at least slow down the chain men.

One area of application is e.g. B. a cover for: door handles, Light switches, push buttons and. a. Depending on the active ingredient can decontaminate the development after each touch, or reduce the transmission of germs.

An inexpensive production of the invention in the below different shapes and variations are possible. An on sentence of the invention with a disinfectant agent appears in all facilities in which the transmission area is particularly large, such as in Schools, kindergartens, restaurants, hospitals sern, telephone booths, public transport, offices, Medical practices etc. make sense.

If the volume in the Chambers has decreased enough and thus the effect subsides, the z. B. blue colored memory material (filler) no longer due to the overlying Layers seem. Another option is to add a dye to the storage material the color of an active ingredient or loss of moisture changed. In this way, the user can see whether the desired one  Effect is sufficient or when a change to a fresh area becomes necessary.

For the application described above, it is proposed that these interchangeable spaces can also be used as advertising media Zen.

Targeted delivery of active ingredients in the application areas in medicine or in personal care

A top layer in foil form which is an "automatic" It is proposed that drug delivery be enabled.

Referring to FIG. 1, layer material of the invention from an adhesive layer 1, a base layer 2, a honeycomb layer 3 and a cover layer 4.

As shown in Fig. 2, the layers mentioned are firmly connected to one another in the inventive layer material. The individual layers can be connected by gluing, but also by welding.

Fig. 3 shows a honeycomb chamber 9, which is bounded by a chamber wall 8 with a lower honeycomb hole 6 and an upper honeycomb hole 7. This honeycomb chamber 9 is part of the honeycomb layer 3 . The base layer 2 and the cover layer 4 close the lower honeycomb opening 6 and the upper Wa ben opening 7th The honeycomb chamber 9 contains the active substance composition with or without fillers.

In Fig. 5 of the invention, in a further development, the non-connected adhesive layer 1, undercoating layer 2, the honeycomb layer 3 top layer 4 and a nonwoven layer 5 Darge represents wherein the nonwoven layer 5 lung a grid-shaped distri comprises of nubs 10th

In Fig. 6, all of the layers mentioned are connected to one another.

Fig. 7 shows a sole for the heel area of a shoe in two parts.

In connection with FIG. 8, the cover layer 2 and the honeycomb layer 3 are arranged on the adhesive layer 1 . The honeycomb layer 3 is closed off at the top by the cover layer 4 . The two-part of the sole for the heel area makes it possible to advantageously achieve a different pressure sensitivity in individual areas of the heel.

The adhesive layer 1 consists of adhesive, Velcro fasteners, magnetic film or other materials which make it possible to attach the layer material according to the invention to or on the most diverse surfaces and also to remove it easily after use. Rubber or plastic film or a material with similar properties are particularly suitable for the base layer 2 . It serves as a carrier material for the adhesive layer 1 . It is possible to color the base layer 2 with a contrast dye in order to support an indicator effect when the content in the chamber 9 has decreased.

The material composition of the honeycomb chambers 9 is designed in such a way that they adapt in height and width to their content and a material exchange between the honeycomb chambers 9 is possible. This can be achieved, inter alia, by introducing a perforation into the chamber wall 8 of the honeycomb chamber 9 . The honeycomb layer 3 is glued to the base layer 2 or connected by thermal fusion.

The honeycomb chambers 9 are filled with a colored liquid, a powder or a gel. The coloring of the filler can also be used as an indicator with which it can be seen whether there is still sufficient active ingredient composition in the layer structure. The less the dye is present, the lower the filling volume and therefore the longer the effect. Should the content of the active ingredient composition in the honeycomb chambers 9 be completely used up, the color impression would also have changed due to the transparent cover layer 4 .

The exchange or transport of the active ingredient in the active ingredient composition takes place through the chamber walls 8 . The size of the honeycomb chamber 9 is selected according to the required volume of the active ingredient composition. In order to enable controlled leakage of the contents from the honeycomb chambers, these are glued to a perforated or special membrane film or to a material which has similar properties, or are bonded to the side walls by thermal fusion. This film used as cover layer 4 should be transparent in order to enable the indicator effect already described by color changes.

By sticking the cover layer 4 onto the chamber walls 8 , adhesive points have arisen which can no longer soak up the active ingredients. The consequence of this is that, for example, a disinfectant effect cannot be guaranteed across the entire surface. For this reason, a fleece layer 5 is applied to the cover layer 4 . The fleece layer 5 supports the skin-friendly properties of the layer material. Furthermore, this also ensures a tactile softness of the surface. It is held in place by the welded side walls of the layer structure. When the layer material is used, for example when used as a disinfectant coating on door handles, light switches, etc., this non-woven layer slips and thus wets the active substance underneath. In order to avoid wetting when not in use, 5 individual, grid-like knobs 10 are applied as spacers on the underside of the fleece layer. These can, for example, be printed using a special screen printing technique. The knobs 10 consist of a liquid-permeable material, for example of a hot-melt adhesive specially developed for this process, such as that used by hot-melt adhesive with the designation Lunatac D014Bg2 or BD4 from Fuller. A commercially available ethylene / vinyl acetate polymer dispersion is also suitable. A pimple diameter of 0.6 mm and a number of 120 pimples per cm ² seem sensible. The grid-like arrangement of the knobs 10 leaves areas in which the open fiber structure of the fleece layer 5 is retained. The areas located between the knobs 10 thus form passage areas for ei nen drug outlet.

The use of the fleece layer 5 is not necessary for all applications.

The active ingredient composition, which is brought into the honeycomb chambers 9 in the form of liquids, powders, gels or vapors, can be combined with swellable polysaccharides or natural, semisynthetic or synthetic polymers. It is important here that the active substance composition is in constant contact with the chamber walls 8 .

The layer material according to the invention and also the individual layers can be produced in a wide variety of forms. The control of the amount or the speed of the active ingredient delivery from the honeycomb chambers 9 is achieved by a targeted selection of the material.

The layered material according to the invention is particularly suitable as an advertising medium. It can be made in a wide variety of colors. The chambers designed here as honeycombs can also be formed from other shapes. The honeycomb layer 3 also contains inlets and outlets or a valve system.

Even when forming a pressure-sensitive layer material according to the invention, honeycomb chambers 9 should preferably be provided in the honeycomb layer 3 in order to achieve better pressure resistance. Are here too, as in FIG. 7 and FIG. 8 can be seen, the layers one above the other.

The use of the pressure-sensitive material according to the invention is not limited to shoe soles but also as pressure damping layers in prostheses, mattress supports, e.g. B. in the treatment of decobitus. The pressure-damping layer structure consists of a very stable and elastic material, which should have similar properties to rubber, e.g. B. Polyurethane. If the layer material is pressed together in certain areas of the honeycomb layer 3 , the gel-like filling material, for example, can only escape sluggishly through the chamber walls 8 . This material behavior enables a uniform damping effect on the entire surface. The cushioning effect of the layered material according to the invention can also be produced by introducing gas, moisture or steam into the system of chamber chambers 9 from the outside via a valve system, thereby enabling targeted control of the internal pressure. This structure of the layered material coupled with a valve system is suitable, among other things, for use as a cushioning mattress pad to treat various complaints.
