CONVENTIONALLY PRICED LIQUID CONTAINER WITH UNIQUE OPTICAL PROPERTIES

Abstract

Method and apparatus for creating highly articulated lenses and lens arrays from the combined effect of a clear-sided container of clear liquid whose sides are of uniform, conventional thickness, and may therefore be manufactured with conventional methods at conventional prices. The container's sides are shaped into the form of the surface of a lens or lens array, and in combination with the clear fluid within, whose index of refraction is close to that of the container wall, performs the function normally performed by a single lens of glass or plastic and focuses light on a plane within, or outside of said container. Such a container can be used both as an enhanced labeling display for clear fluid containers such as water, soda, liquors, liquid soap and many other liquid products, as well for as a display device only, enabling otherwise impractically thick and expensive lenses.

10. The container according to claim 1, in which a flat or curved, substantially planar, liquid-filled container functions primarily as a display lens or lens array, rather than as an ordinary practical fluid container, being substantially thinner in respect to its width and height.

23. The container according to claim 15, wherein the label location region is defined by an indented area within the container.

24. The container according to claim 22, wherein the label contains an image printed with insoluble inks and wherein the label is a thin flexible substrate which is adapted to be inserted through mouth of the container.

25. The container according to claim 24, wherein the substrate is folded to be inserted through the container mouth, becomes unfolded after insertion to be essentially planar and dispersed at the focal plane.

26. The container according to claim 25, wherein the container has spaces which locate the substrate at the focal plane.

27. The container according to claim 15, wherein the lenses with contained fluid define a focal plane within the container.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Several embodiments of the invention will be described, but the invention is not limited to these embodiments.

[0020] FIG. 1 shows a perspective view of a substantially rectangular container A, whose front, or first side is formed in the shape of the surface of a lens array, which, acting in combination with the clear fluid inside of it which completes its lens effect, has a focal plane at the outside surface of its rear, opposed or second side, at which plane is affixed a label with a corresponding image.

[0021] FIG. 2 shows a double-container, made from two, attached containers, whose labels just fit in the combined, indented space between them, at the focal planes of the outer sides, which double container can hold two distinct liquids, such as oil and vinegar or shampoo and conditioner, wherein each of the two containers are accessible only from its own container mouth. The indented spaces may be made in such a way as to allow either affixed labels, or a double-sided label, inserted after assembly.

[0022] FIG. 3 shows a single-formed version of the two attached containers, wherein the interior spaces of the two containers are joined and having a single mouth with a single, double-sided label inserted as in the double container of FIG. 2.

[0023] FIG. 4 shows a container whose lensed sides focus within the container at the plane of an inserted image, printed on a flexible substrate, which is rolled or otherwise compressed, so as to be able to be inserted through the container mouth, and subsequently springs open, disposing itself at the focal plane of the lensed sides, by means of spacers formed into the flexible image or the container.

[0024] FIG. 5. shows an enlarged view of a single lens element within an array, and the paths taken by light rays in a fluid-filled versus an empty container. The container wall A is of a uniform thickness, which, in a plastic bottle may be as thin as about 0.005. If the container, as shown in area B, is empty, the light rays, D will pass through the wall with little deviation to their direction, since the change in refractive index of 1 from the outer air, to very approximately 1.5 of the glass or plastic (somewhat higher for PET plastic, commonly used in plastic bottles) is reversed when the rays pass from the wall back to air inside the container. The result is that the rays do not focus.

[0025] However, when the container is filled with a substantially index-matching liquid, as shown in area C, the thin, curved surface of the container wall acts in conjunction with the contained fluid as a single lens, much like a doublet lens made of two types of glass, and the light rays focus as determined by the radius of curvature of the container surface. The container's label E on the side opposite the lens array, and whose image corresponds to the lens array and faces inward, lies at the array's focal plane. For the sake of the illustration the light rays are shown traveling into the container, but of course travel in both directions and an observer on the array-side of the container will see label's inner image as an optical display showing three-dimensionality, motion, or any of those properties commonly associated with such lens arrays.

[0026] Although several embodiments have been described, the present invention is not limited to these embodiments, and other variations and modifications can be made as will occur to those in the art. The scope of the invention is defined only by way of the following claims.
