DETAILED DESCRIPTION OF THE INVENTION

Referring now to FIGS. 1-4 , a beverage container 10 constructed in accordance with this invention consists of a body 12 having a cylindrical sidewall 14 , a top end wall 16 and a bottom end wall 18 . The bottom end wall 18 is usually bowed inwardly leaving a concave space under the container 10 . Disposed around the sidewall 14 is a sleeve 20 .

As shown in FIG. 2 , the sleeve 20 has two ends 22 , 24 that are joined seamlessly when slipped over body 12 . A display 26 is formed on the sleeve 20 . Preferably the display 26 is made of a flexible material such as light emitting polymer (LEP) available from Cambridge Display Technology of Cambridge, U.K. Between display 26 and one end 22 , the sleeve 20 may be provided with a zone 28 . This zone (as well as a zone adjacent to end 24 , not shown) may be reserved for standard printed matter containing the identification of the manufacturer, the contents of the container 10 and so on. This printed matter is provided in case the display 26 fails. Alternatively, the display 26 may extend continuously all around the body 12 and the printed matter may be provided on either the top wall 16 or the bottom wall 18 .

As shown in FIG. 3 , the display 26 is preferably composed of three layers: a plastic base 32 which is used to provide strength and dimensional stability to the sleeve 20 , the LEP layer 34 (including the associated drive conductors), and a protective layer 36 . The protective layer 36 is also made of a plastic material and is transparent or at least translucent so that the images formed by the LEP are clearly visible.

A control circuit together with a battery is incorporated into a case 38 disposed, for instance, in the space formed by the bottom wall 18 , or on top wall 16 as shown in FIG. 1 at 38 ′.

Referring now to FIG. 4 , the control circuit 42 includes a microprocessor 44 , a memory 46 , an external interface 62 and a display driver 48 . The memory 46 is used to store digital data for various images. The microprocessor 44 retrieves this data and uses the same to generate commands to the display driver 48 . The display driver 48 generates electrical signals in response to the commands from the microprocessor 44 . These electrical signals are sent to display 26 . Power to the control circuit 42 is provided by a battery 52 .

Also associated with the control circuit 42 are three sensors 52 , 54 , 56 . These sensors detect when certain predetermined conditions exist as described below.

When the container 10 is disposed in a closed box for shipping, or inside a refrigerator, there is no need for any images to be generated and accordingly the display may be turned off to save energy thereby extending the life of battery 50 . Sensor 52 comprises a light detector. As soon as it detects light, it sends a corresponding signal to microprocessor 44 . The microprocessor 44 is then primed to show images on the display 26 as discussed more fully below.

As seen in FIG. 1 , top wall 16 of container 10 is provided with a closing tab 40 . This tab 40 is removed or lifted by a customer to open the container 10 . If the container 10 is pressurized, for example, if it holds beer or soda, its body 12 undergoes a slight distortion when the tab 40 is opened. Sensor 54 could be a stress sensor (for example, a piezoelectric transducer) which detects a flexure of body 12 . Alternatively, the sensor 54 may be a standard miniature switch which senses when tab 40 is opened or removed. In response to the opening of the tab 40 , the sensor 54 sends a corresponding signal to the microprocessor 44 .

Sensor 56 may comprise an activating switch 56 A such as a mechanical switch which may be selectively activated by a customer. The switch 56 A may be attached to the sleeve 20 , as shown in FIGS. 1 and 2 . Alternatively, the sensor 56 may be a touch sensitive sensor embedded into the sleeve which is activated when a customer lifts the container. For example, the touch sensitive sensor may overlap the zone 28 shown in FIG. 2 .

To improve the dynamic nature of the container 10 , image, sound or other data may be transferred between it and an external source 64 . For this purpose, an external interface 62 is provided which may be, for example, a serial or parallel port, an IR, RF coupler, or other similar hard-wired coupling. Alternatively, the interface 62 could be a wireless modem capable of exchanging data with the external source 64 over an Intranet- or Internet-based network.

The transfer of data may be automatic or it may be triggered, for example by an appropriate sensor such as sensors 52 , 54 , 56 or by activating another switch provided for this purpose. The addition of the external interface could serve multiple purposes. For example, a user can generate an image or sound file on his computer (not shown), or download it, for example from the Internet, and then transmit it to the microprocessor 44 via interface 62 . The interface 62 can then store this file in the memory 46 . Similarly, data could be transferred from the container 10 to an external source 62 in response to an advertisement displayed on the container 10 activated by an appropriate sensor such as the stress sensor 54 .

The container 10 may also be provided with several piezoelectric or ceramic speakers 58 . These speakers 58 may be disposed on the sleeve 20 and/or on the top wall 16 as shown. Alternatively, the speakers may be provided in the form of a sheath (not shown) incorporated into sleeve 20 .

The display 26 comprises a number of pixel elements depending, for example, on the size of the container 10 . Even for a large container, a display of 480.times.640 pixels may be sufficient. If memory 46 has a storage capacity of 10 M bytes, and if data compression is used, it can hold data for up to five hundred color images for the display 26 . Alternatively, instead of pixels, the display 26 may comprise several discrete image elements having distinct shapes, the image elements being selectively activated by the microprocessor 44 . The images can be shown one at a time, or may be displayed in a rapid succession to generate moving images. These moving images may be accompanied by appropriate sounds from the speaker 58 .

A typical operation for a container 10 is now described in conjunction with FIG. 5 . In this Figure, initially, the control circuit 42 is in an idle mode (step 100 ). In this mode the light sensor 52 is monitored (step 102 ). If light is sensed, it is assumed that the container has been placed on a shelf in a store and accordingly, a preselected presentation A, consisting, for example, of a plurality of images shown in succession is started in step 104 . In step 106 the presentation A continues to be played until one of several events take place. Alternatively, presentations may be delayed until one of these events occurs.

In step 108 a check is performed to determine if sensor 56 has been activated, by a customer or potential customer. For example, adjacent to switch 56 A, a sign (which may be presented by display 26 at 60 ) may be provided with the legend ‘PRESS HERE TO GET MORE INFORMATION’ If the sensor 56 is a touch sensitive switch, it is automatically activated when the container is lifted, as discussed above.

Returning to FIG. 5 , in step 108 , if the sensor 56 is activated then in step 110 the data for a second presentation B is retrieved from the memory 46 and is shown in step 112 on display 26 . Presentation B may provide further information about the beverage in container 10 . Alternatively, in response to the activation of sensor 56 , a different unrelated presentation may be shown. For example, the legend may indicate that a presentation is available regarding a coming movie attraction. At the end of presentation B, the system recycles to step 100 .

If in step 108 it is determined that sensor 56 has not been activated, then in step 114 a check is performed to determine if sensor 54 has been activated, indicating that the container 10 has been opened. If in step 114 the sensor 54 has been activated, then in step 116 the data for a third presentation C is retrieved from the memory 46 and shown by display 26 in step 118 . This third presentation C may be related to other products made by the same company or promotional data informing the customer of prizes, goods or services associated with the sale of the container 10 . Alternatively, the third presentation C may concern an unrelated product or service. At the end of the third presentation C, the system may recycle to step 100 . Some, or all the presentations A, B, and C may be multimedia presentations consisting of still or moving images combined with sounds emitted from speakers 58 .

If in step 114 it is determined that sensor 54 has not been activated then the system returns to step 106 and continues displaying the first presentation A.

The mode of operation described in FIG. 5 is presented merely as an illustration of the flexibility of the system. The number of presentations, their content and length is limited only by the information storage capability of the memory 46 . Obviously many different types of presentations and modes of operations can be stored and sequenced as well. Moreover, other types of sensors may be added and some or all of the sensors 52 , 54 , 56 may be omitted.

The subject invention has been described in association with a beverage container. One skilled in the art will appreciate that with little or no modification the invention may also be used to show still pictures, moving pictures, or multimedia presentations on various other types of containers as well, such as plastic or glass bottles, cardboard or plastic boxes and other containers used for packaging and dispensing various foods, household and any other types of products.

Numerous modifications may be made to the subject invention without departing from its scope. The present embodiments are therefore to be considered in all aspects as illustrative and not restrictive in any manner.
