Abstract

A label for a product, or a promotional device, including a flexible light emitting polymer screen.

Description

LABELS AND PROMOTIONAL DEVICES

The present invention relate to labels and promotional devices which include a display device and in particular to a display device for incorporation into or onto products for displaying information to a user or purchaser of the product e . g. for promotional purposes or for conveying statutory information such as instructions for use.

There have been developments over recent years in devices for conveying information to a user or purchaser of a product and in promotional devices, for example in competitions. Leaflet labels have been known for a number of years and such leaflet labels consist of a self-adhesive label incorporating a folded booklet or leaflet for attachment to a product. The leaflet label, when unfolded, reveals a large amount of information which is printed on the leaflet or booklet, and the printed area of the leaflet label is significantly larger than the footprint area of the leaflet label which is required for labelling the product. In this way, a large amount of information can be incorporated into a relatively small labelling area. Examples of leaflet labels, in particular overlaminated leaflet labels incorporating a self-adhesive plastics overlaminate for protecting the leaflet label, retaining the label in its closed configuration and permitting reliable repeated access to the information in the label are disclosed in my European Patent Nos . EP-A-0594560 and EP-A-0628941.

It is also known to incorporate into products electronic devices for conveying information to the user or purchaser of a product. This information may relate to the intended use of the product or safety information, or alternatively it may relate to a promotion concerning the product, for example a competition, a lottery or a money off promotion. For example, my EP-A- 0233077 relates to a container for a product which incorporates a removable closure and wherein removal of the closure from the container triggers the generation of audible speech from a speech synthesiser associated with the container. Such an invention has been used commercially in promotions of products, for example in competitions wherein a small number of winning containers in a competition include the speech synthesiser in accordance with my earlier invention to indicate a winning product when the container is opened. The container may be, for example, a drinks can or a packet of dry goods, such as a breakfast cereal.

There is a generally increasing need to display information on and in relation to products. Such information relates not only to promotional purposes, but also to the provision of statutory information, such as safety information and product warnings. There is also a need to display in relation to a product information which can be variable, and in particular can be updated readily over time.

The present invention aims to meet these needs .

Accordingly the present invention provides a label for a product, or a promotional device, including a flexible light emitting polymer screen.

The label may incorporate, or be interconnected with, an audible generator for emitting sound through the screen or a speaker, in conjunction with an image displayed by the screen.

The present invention will now be described, by way of example only, with reference to the accompanying drawings, in which: -

Figure 1 is a perspective view of a container labelled with a label in accordance with a first embodiment of the present invention;

Figure 2 is a perspective view of a box for a compact disc which is labelled with a label in accordance with a second embodiment of the present invention;

Figure 3 is a perspective view of a leaflet label incorporating a flexible light imaging polymer screen in accordance with a third embodiment of the present invention;

Figure 4 is a perspective view of a label comprising a cover for a printed publication in accordance with a fourth embodiment of the present invention;

Figure 5 is a perspective view of a promotional device in accordance with a fifth embodiment of the present invention; and

Figure 6 is a perspective view of a container labelled with a label in accordance with a sixth embodiment of the present invention.

Referring to Figure 1 there is shown a container 2 in the form of a bottle which is labelled with a tubular sleeve-type label 4 in accordance with a first embodiment of the present invention. The label 4 comprises a flexible light emitting polymer screen 6 which is carried on an underlying substrate 8, for example a plastics layer covered on its rear face which a pressure-sensitive adhesive so that the substrate is self- adhesive. The flexible light emitting polymer screen 6 is connected to a power and control device, indicated generally at 10, for providing the screen with electrical power in a controlled way to ensure that the correct image is displayed by the light emitting polymer screen 6. The power and control device 10 includes a source of electrical power, for example a battery or a solar cell. The power and control device 10 may include a switching mechanism for switching on and off the light emitting polymer screen 6. For example, the switching device may be operated by detecting light, sound, temperature, humidity or water or other climatic factors or by touch thereby to switch on the screen to display a desired image. The desired image may be preformed in the screen. Alternatively, the image may be a variable image, with a display being pre-programmed into a microprocessor of the power and control device 10. The displayed image may comprise text and/or pictures which may be static or moving, i.e. a video image. The image may be coloured or in black and white. The screen could incorporate a hologram. The screen could be divided into a plurality of areas so that multiple images can be displayed. Flexible light emitting polymer screens are known in the art. Such screens consist of a transparent substrate on which has been deposited, in turn, an electrode layer, two light emitting polymer layers, and a grid of electrodes. When a forward voltage is applied across the two light emitting polymer layers, the light emitting polymer layers are illuminated and the grid of electrodes is patterned so as define grid cells which can make up an image. When only a single image is to be displayed by the light emitted polymer screen, the patterned grid of electrodes is defined and connected to the power and driving control device 10 whereby only selected grid cells are illuminated when the light emitting polymer screen 6 is switched on. In this way, the selective image may be displayed. When the screen 6 is intended to display an active changing image, then each grid cell which is defined by a respective part of the grid of electrodes requires a self-contained transistor associated therewith which can be controlled to switch on or off the respective grid cell on receiving a signal from the power and control device 10, which typically then includes a microprocessor .

The screen may be adapted to be a touch screen or audibly sensitive, for example being voice activated.

In the embodiment of Figure 1, the container is also provided with a closure 12 incorporating a speech synthesis device 14 as disclosed in my EP-A-0233077. Alternatively, any other audible generator could be employed. For example, the audible generator may include a speaker and/or may be integrated into or behind the screen 6.

In accordance with the invention disclosed and claimed in EP-A-0233077, the closure of the container, is provided therein or in association therewith with a speech processor which is triggered to generate synthesised speech when the closure 12 is removed from the container 2. The speech synthesiser may be driven by a common power source with that of the light emitting polymer screen 6. The disclosures of EP-A-0233077 are incorporated herein by reference thereto.

Referring to Figure 2, a second embodiment of the present invention comprises a light emitting polymer screen 16 in the form of a self-adhesive label which is adhered to a product 18, such as, in the illustrated embodiment, a plastics box for a compact disc. Alternatively, the product 18 may comprise a cigarette carton, or a case for packing a number of products. As for the embodiment of Figure 1, the label is self-adhesive, with the adhesive being permanent or removable. The package of Figure 2 may additionally be provided with a speech synthesis generator, similar to that described hereinabove with reference to Figure 1, for generating synthesized speech when, for example the box is opened. A power and control device 20 for the screen 16 may be disposed within the box 18.
