DE102008020474A1 - Adhesive label for use in sanitary or kitchen objects, has thermochrome coating such that presentation is visible by heating, on surface of sanitary or kitchen object provided for wetting with fluid - Google Patents

Abstract

The adhesive label (2) has a thermochrome coating such that a presentation is visible by heating, on a surface of a sanitary or kitchen object provided for wetting with fluid. The sanitary object is a urinal, a shower, a bathtub, a washbasin, a restroom, a mirror tile, a floor tile or a mirror. The thermochrome coating covers a presentation layer containing the presentation.

Description

The The present invention relates to wet area stickers (Urinals, showers, sinks, bathtubs etc.), which contain thermochromic substances provided by which they can show advertisements or pictures, when using with temperature-intensive (hot or cold) liquids in Come in contact.

Thermochromism is the reversible change of spectral properties on heating or cooling. Usually this change is visible. It is observed in complexed metals, in inorganic and organic materials, in all phases of matter, but mainly in solids or solutions (eg. US 4717710 ). There are thousands of examples in solids and liquids, some new applications are given here.

So far There are several different games in the urinal area to increase the play instinct to challenge the men, such as B. score goals etc. However, through the physicality of these products will be the urine stream is distracted and splashes on walls, floors and the urinating person.

Of the crucial disadvantage is the urinal with one of these games contaminated by small amounts of foreign matter (vomit etc.), clogged very easy. Likewise, the game must be removed from the urinal and getting cleaned. This is a no-brainer and a high health risk for the cleaning staff.

aim The present task was therefore to the prior art enrich and remedy this disadvantage.

The The object is achieved by the use as claimed 1 and the sanitary or kitchen object according to claim 6 solved. Advantageous embodiments are described in the subclaims.

The Stickers can be found in every urinal in every imaginable way Molds are introduced. Due to their thermochromic properties You can use all imaginable pictures, motifs, logos, advertisements etc. show.

The, due to the thermochromic colors or coatings, not yet visible Motives are heated by the warm urine stream and so visible.

Around It has to be able to fully see the motif be completely heated. This event awakens the Curiosity of the urinating, so he will try only in the Urinal to meet to see the motive.

There the motives can be varied from urinal to urinal, no boredom arises for the men. So be all urinals are used evenly. The urinals can not clog as easily as the stickers are no disturbing foreign body.

By Purposeful urination does not urinate urine out of the urinal, whereby walls, floors and clothing of the urinating do not be stained. This provides a time saver and a lower health risk for the cleaning staff there.

There it is in this invention is a sticker, they can be used in and on all previously installed urinals, without costly installations.

One particular advantage of this invention is that through these stickers large new advertising spaces are being created by the industry can be used.

The Use of the stickers is not only applicable in the field of urinals. They can also be used in all other wet areas be such. Showers, bathtubs, sinks, toilets, tile mirrors, Floor tiles, mirrors etc.

The Invention will be described below with reference to embodiments described in more detail with the accompanying drawings. Show it:

1 - Sketch of a urinal in side sectional view with a thermochromic sticker;

2 - perspective view of the urinal on the thermochromic sticker in the cool state;

3 - Perspective view of the urinal on the thermochromic label in the heated state;

4 - sketch of a thermochromic sticker with flat thermochromic layer;

5 - Sketch of a thermochromic sticker with patterned thermochromic layer.

1 leaves a sketch of a urinal 1 recognize in the side sectional view, on a provided for wetting with fluid collecting and deflecting surface with a thermochromic sticker 2 is provided. The urinal 1 is in a conventional manner to a wall 3 screwed.

Of the Thermochromic sticker is designed so that a motif only when heated by the impinging fluid above a predetermined temperature Be visible and after draining the fluid and a cooling phase becomes invisible again.

2 leaves the urinal 1 out 1 recognize in perspective view with a cool sticker. It becomes clear that the sticker 2 except a non-thermosensitive printed lettering no motif shows.

After heating by wetting with a compared to the ambient temperature of about 20 ° C warmer fluid is, as in 3 Outlined, a motive is visible through the warming. The temperature limit from which the thermochromic sticker 2 a motif should be at about 28 ° C to 35 ° C.

4 leaves a sketch of a thermochromic sticker 2 with a base layer 5 recognize, on the one presentation layer 6 is applied with a pattern. The base layer 5 can be printed in a conventional manner, for. B. with a screen printing process. The presentation layer 6 is with a flat thermochromic layer 7 covered, which becomes transparent when heated by impinging fluid below a threshold temperature of z. B. 30 ° C, however, is opaque, so that the subject on the presentation layer 6 then invisible. On the thermochromic layer 7 Optionally, a permanently visible print can be added 8th For example, be applied with a text advertising notice.

5 Leaves a sketch of another embodiment of a thermochromic sticker 2 recognize, which is also a base layer 5 Has. On the base layer is a thermochromic layer 7 applied, which is patterned in the form of the pattern to be displayed. Upon heating by impinging fluid, by selecting the materials for the thermochromic layer 7 In addition, this limit temperature is in the thermochromic layer 7 pattern visible through patterning. Below a limit temperature of z. For example, at 30 ° C, the pattern is invisible and has the same color and / or contrast as the surrounding areas of the pattern. The thermochromic layer 7 including the pattern can z. B. become transparent below the threshold temperature, while when heated only the areas defined by patterning of the layer 7 become opaque and possibly accept defined colors. In this way, a black-and-white motif and possibly color additives make a colored motif recognizable by contrast when wetted with fluid.

The sticker 2 can protect with a protective film 9 be covered.
