Patent ID: 8814379

Claim:
A self-contained illumination device for attachment to a container, the device comprising: a. a pad formed of a first layer and a second layer wherein: (1) the first layer: (a) is formed of a liquid-impervious material, (b) is flexible and at least partially foldable, (c) has first and second opposing major surfaces wherein: i. a thickness between the first and second major surfaces is in the range of 0.15 to 0.4 mm, ii. the first major surface has a central region surrounded by an adhesive region, and iii. the second major surface of the pad is printable; (2) the second layer covers and releasably attaches to the adhesive region of the first major surface of the first layer, b. illumination device electrical elements provided on a rigid circuit board, the circuit board being attached to the central region of the first major surface of the first layer, whereby upon removal of the second layer from the adhesive region of the first layer, the adhesive region can be adhered to, and can adopt the contour of, a surface of a container in liquid-tight manner, with the circuit board situated between the container and the central region of the first layer.
