Label and the like

The present invention is a label which is characterized in that it is whole or partly from at least one, one or both sides transparent, colorless or transparently colored double-walled plastic film, which is closed on all sides and contains a filling, which, depending on the temperature, are reversible from colorless or from a certain color to a or changes to another color or changes into several colors one after the other.

The new label is intended in particular for beverage containers, such as bottles and drinking glasses, for example, and shows a special aesthetic effect that is due to the temperature of the beverage in the container. In addition, it also allows the consumer to optically determine the correct beverage temperature range.

The subject of the application also includes label-like objects such as stylized seals, as e.g. can be used for spirits bottles and drinking glasses, as well as badges, e.g. to clip on.

In a preferred embodiment, the label is made wholly or partially made of a transparent, colorless or transparent tinted on at least one side, on all sides sealed plastic film, which by adhesive, but especially welded connections, in several of each other separate chambers is subdivided, which, optionally only partially, contain the filling, wherein preferably the fillings in the individual chambers have a color change or an appearance of color in each case show different temperatures and may be different in color.

The filling preferably consists of at least one, in particular cholesteric, liquid crystal, if appropriate in the form of a paste; it can contain further additives, in particular customary dyes and / or pigments.

Depending on the type of beverage for whose container the label is intended, for example, the fillings show one or more color changes or the appearance of color at certain temperatures in the temperature range from about -5 to about 20 C.

For example, red wine bottle labels, if necessary only partially, can consist of one or more double-walled Plastic sheets with a filling are made that

309839/0062

The aforementioned with a rising temperature in the above temperature range, e.g. at approx ⁰ C shows a color change from, for example, red to green. The consumer can then see that the wine is heated properly, when both chambers or parts of the label film having a red color, since this then has a temperature between about 10 ⁰ C and about 1 * J ° C.

Bottle labels for, for example, grain brandy, on the other hand, can include, for example, only a single part, which consists of such a plastic film, with a filling that changes color, for example from green to red, when heated ^ .B. 5 ⁰ C, and vice versa when cooling below 5 ° C shows than. a plurality of such parts with color various fillings, which show a color change or appearance of color at different temperatures, and. in the form of ornaments, images or characters, and the like are integral parts of the label, which ¹ the latter is flexible or more or less can be rigid.

In a further preferred embodiment, the label consists of a more or less rigid plastic part of substantially round or oval shape, which is designed as a seal or badge, on which or within which the filled, preferably in several chambers of different shapes and / or sizes subdivided double-walled plastic film is arranged, wherein, if the plastic film is arranged within the plastic part, the latter at least in the area

309839/0062

- Il -

the plastic film and is transparent on one side at the top.

Since the flexibly designed new labels, which are made from the aforementioned double-walled plastic film, which is preferably divided into several, in particular letter or number-shaped chambers, beetehen or at least include such a film in They can usually be firmly attached to the container, especially for drinks, e.g. by gluing expediently have a self-adhesive layer on their back.

More or less rigid, e.g. designed as a seal; Labels, however, in which one or more such Filled double-walled plastic films are only an, e.g., an ornamental component, are in usually not firmly attached to the container but only more or less loosely connected to it. For example Such a label in the form of a seal can be attached to a cord, e.g. by means of a loop around the neck of the bottle, attached to a bottle. Such labels in the form A seal or the like can also be permanently attached to everyday objects such as drinking glasses will.

Badges, e.g. for sticking on, in which one or more such plastic films, preferably individual filled chambers in the form of characters, such as letters, numbers and / or symbols, such as symbols,

309839/0062

on the other hand, have a known, e.g., needle-like fastening means their back on.

Black, white or colored characters can be placed on the double-walled film, for example by printing on the inside or outside of the. upper foil wall. If the writing is black, then in the case of a colorless film it is generally always recognizable, regardless of the thickness of the filling in the film. In a preferred embodiment, the eg printed character has any color which corresponds to the color of the background, whereby the character can no longer be recognized or only becomes recognizable at a certain temperature that can be determined by the type of filling. For example, a "red" typeface only appears when the filling of the film changes from red to, for example, yellow at, for example, k ° C. In the case of a colorless filling, the background is formed by the lower film wall, which is opaque; Filling - whereby the lower film wall is usually not colored opaque - it is formed by this filling before and after its temperature-related color change.

In summary, this results in the following possible combinations of lettering and its background :

1. Black font, colorless filling, black background: font becomes visible when the color changes in all areas;

309839/0062

2. Text red, filling red, any background: text becomes visible when the color changes to green, blue;

3. Font green / blue, filling red, any background: font visible before color change, on cover green / blue invisible;

4. Font green / blue, filling color lime, background black:

Text visible before the color change, visible with red, becomes invisible with green / blue change.

The subject matter of the invention is exemplified on the basis of Figures showing schematically special embodiments represent, described in more detail.

Fig. La shows a plan view and Fig. Ib in a section through the plane EF of Fig Welded connections (3) is closed, which is divided into several chambers (2a, b, c, d) by further in particular welded connections (3), of which the chambers (2b) and (2c) formed as letters in the present case have a filling (1 ), preferably comprised of a liquid crystal, in particular a cholesteric liquid crystal, which, depending on the temperature, changes from colorless or a certain color to one or another color or changes to several colors one after the other. The label can have a self-adhesive layer on its back. The filling (1) of the chambers (2b) and (2c) can be the same or different in color and an appearance of color or a change in color with the same or different

309839/0062

Show temperature. Of course, the chambers (2a) and (2d) can also have such a filling (1) or contain a filling made of conventional pigments or dyes.

Fig. 2a shows a plan view of a label in the form of a seal for beverage bottles according to the invention, which is a round part made of a double-walled plastic film that is transparent, colorless or transparently colored on one side and has four chambers (2e, f, g, h), which is closed to the outside by a further weld seam (3), while the other part (4), which in the present case is round and rigid, consists of plastic. The doppeiwandige plastic film, whose chambers (2e) and (2g), for example, a red below about 10 ⁰ C filling, which turns at about 10 ° C in green, and the chambers (2h) and (2f), for example, a blue at room temperature paint, which turns green at around + 15 ° C, is firmly attached to the plastic part (4), e.g. by gluing or welding, for example, as shown in Fig. 2b in a sectional view along the plane AB of Fig. 2a, in a recess corresponding size in part (4), which can be transparent or opaque. If such a seal-like label is attached firmly or loosely to a liquor bottle, for example by means of a cord connection by means of a loop looped around the neck of the bottle, the consumer can see that the contents of the bottle are at the correct drinking temperature when all chambers (2e to h ) are the same color. In the present example he would see that if all the chambers are yellow,

309839/0062

in the case of brandy as the bottle content, this has the correct drinking temperature, while in the case of red chambers it has the correct drinking temperature (2e) and (2g) recognizes that the bottle contents are too cool, and with blue chambers (2f) and (2h) would recognize that the contents of the bottle are too warm.

The plastic part (Ί), for example made of polystyrene, can in turn consist of 2 parts (4a) and ( ¹ Ib) or ( ¹ Ic) and ( ¹ Id), one of which ( ¹ Ib) or both ( ¹ Ic) and ( ¹ Id) can have a recess (5) for receiving the double-walled plastic film, as shown in Fig. 2c and Fig. 2d in a representation of the section through the diameter of a circular badge. At least a portion of the plastic part can in this case just to the outside (part ¹ Ia of Fig. 2c) or convex (part ¹ Ic of Figure 2d.) But may also be formed in relief and the like. it is transparent at least in the area of the double-walled plastic film underneath, so that the change in color of its filling can be seen.

The two parts ( ¹ Ia) and ( ¹ Ib) or ( ¹ Ic) and ( ¹ Id) are expediently, depending on the type of plastic material they are made of, by gluing or welding, for example thermally using ultrasound, high-frequency welding and like., firmly and permanently connected to each other.

However, the plastic part ⁽¹ O may be also formed seamlessly and containing the plastic film in its interior and it can then be prepared for example by overmolding of the plastic film with a transparent casting resin

309839/0062

will.

Expediently, the one lying on the beverage container Plastic part (4b) or (Md) made thinner than the upper part (4a) or (4c), so that a good heat transfer from the tray contents is guaranteed is.

Fig. 3a shows the top view of another embodiment of a seal-like or plaque-like label, in which the part (4) is a rigid ring made of plastic, in the ring opening of a,. a plurality of chambers (2i, k, 1, m) designed in the form of a number, circular, double-walled plastic film is arranged, the plastic film and the chambers being closed by adhesive, but especially welded connections (3).

In the present example, the chambers (2i) and (2k) contain a filling made of the same liquid crystal, while the chambers (2m) and (21) contain a filling made of a different liquid crystal that of another Temperature shows a color change and possibly has a different basic color. Of course but e.g. the chamber (2k) can have a filling that differs from that of the chambers (2i) and (2m) and (21) in terms of color and / or in terms of their coloring behavior in Depending on the temperature is different.

FIG. 3b is the representation of a section along the plane CD through the seal-like or label-like label according to FIG. 3a.

309839/0062

In plan view, Fig. 4a shows a label with a plastic part ⁽¹ J), which is designed as a rigid rectangular frame opening in which one, arranged rectangular by adhesive, but especially welded joints (3) sealed on all sides, transparent double-walled plastic film (2) is ; on the inside of which letters (6) are printed. From Fig. 4b , which shows a section along the plane GH of Fig. 4a, it can be seen that the frame-shaped plastic part consists of 2 parts (4e) and (4f), which after inserting the film (2) into the recess provided for this purpose for example, by gluing or welding, firmly connected to each other and to the film.

Of course, characters and the like can also be attached to the outside of the transparent film (2), and one wall of the film (2), which Opposite the transparent film wall provided with the characters and the like, opaque be.

Of course, a label can also consist of a double-walled, several filled chambers, e.g. in the form of of plastic film containing letters, on which letters are arranged, e.g. printed, are or include such.

The filled one forming the label or part of it double-walled plastic film can be made by having two thermoplastic films Plastic, after which one of the same, which preferably has small depressions in the form of chambers,

309839/0062

with a layer of the filling, expediently in paste form, e.g. by spraying or brushing on has provided, welded to one another at the edges and at the desired points, e.g. by thermal Welding or by high frequency or ultrasonic welding. ,
