Container illumination device

摘要

A self-contained illumination device (10) for attachment to a container, e.g. to the base of a bottle, comprises a printed circuit board (12), with LEDs (14) attached to the central region of a liquid-impervious flexible pad (11). The central region is surrounded by an annular adhesive region which is arranged to attach the pad to the container in liquid-tight manner. The pad comprises a base layer (32) of plasticized paper or PVC, covered by an adhesive layer (34) and, before attachment to the container, a peripheral layer (36) of a release paper.

1. 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 surfaceswherein:
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, andiii. 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.
