Wrap around lenticular lenses and fabrication method for clear walled containers
View Patent ↗A container for producing a graphical image within the container. The container includes a container wall with a front portion and a rear portion. A label is included that extends about the circumference of the container with an inner surface contacting an exterior surface of the rear portion of the container wall and contacting an exterior surface of the front portion of the container wall. The label includes a lenticular lens array integral with the label to include a plurality of lenses formed, such as through embossing, on the outer surface of the label. The lenses have a focal point on or about the rear portion of the container wall with the lenticular lens array positioned near the front portion of the container wall. A printed image is provided and positioned proximal to the focal point on the inner surface of the label.
1. A container adapted for producing a graphical image observable by a viewer external to the container, comprising:
a container wall having a front portion and a rear portion separated by a distance, the container wall defining an interior space for receiving a volume of a liquid;
a label extending about the entire circumference of the container with an inner surface contacting an exterior surface of the rear portion and an exterior surface of the front portion of the container wall, wherein the label further comprises a lenticular lens array integral with the label including a plurality of lenses formed on an outer surface of the label with a focal point on or about the rear portion of the container wall and wherein the label is positioned with the lenticular lens array positioned proximal the front portion of the container wall; and
a printed image proximal to the focal point;
wherein the label is applied to the container wall by heat shrinking the label, the lenticular lens array being configured prior to the heat shrinking to produce the plurality of lenses with the focal point after distortion of material in the label created in the heat shrinking, whereby no adhesive is positioned between the lenticular lens array and the container wall or between the printed image and the lenticular lens array.
2. The container of claim 1 , wherein the container has a circular cross section and the container wall defines a diameter of the container and wherein the lenticular lens array is configured for the container diameter to focus on the focal point, and wherein the label has a thickness between about 2 mils and about 16 mils.
3. The container of claim 2 , wherein the plurality of lenses are embossed onto the outer surface of the label.
4. The container of claim 3 , wherein the embossing comprises heating the label to a temperature higher than about 300° F. and wherein the embossing is performed using a chill roller, an engraved or etched embossing plate or roller, a flat letterpress embossing die, a cylinder letterpress, or flexo plates.
