ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a novel and useful liquid containing optical device.
Containers holding material such as liquids, are typically used at entertainment events such as sports arenas, music concerts, political gatherings, and like activities. Due to large number of persons attending such events, it is often necessary to carry a pair of binoculars, or a telescope to see the subjects providing such entertainment or persons conducting the activity. It is also common to consume food and drink at such activities. The latter is often contained or carried in a bottle, which is typically molded from plastic material such as polystyrene, polypropylene, and the like. When the contents of the bottle have been consumed, the bottle is often discarded creating a burden in the collection and disposal of the same.
An optical device which possess liquid carrying capabilities would be a notable advance in the field of useful articles.
BRIEF SUMMARY OF THE INVENTION
In accordance with the present invention a novel and useful liquid containing optical device is herein provided.
The device of the present invention utilizes a housing having a bottom, and a side which sealingly engages the bottom. The side extends outwardly from the bottom and forms an open chamber. An exterior portion lies opposite the chamber on the housing outer surface. The side terminates in a mouth forming an entrance to an inner chamber. The chamber is capable of holding a material such as a liquid, solid, or gas, for use by the bearer of the optical device.
A cap is also found in the present invention and extends transversely relative to the mouth of the housing open chamber. The cap is capable of closing the chamber to prevent liquid from egressing from the open chamber through the mouth of the housing. The cap is removably held to the side of the housing to permit the user to gain access to the liquid in the open chamber.
In addition to the liquid containing capabilities of the optical device of the present invention, the device may be employed to adjust a visual angle of an object adjacent to the housing. That is to say, the material containing optical device may be formed into a telescope, microscope, and the like. In this regard, a first optical element is located in the bottom of the housing. Where a Galilean telescope is being formed, the first optical element may be an objective lens of the double convex type. The first optical element may be imbedded in the bottom of the housing or molded contiguously during the formation of the housing. In such a case, the housing may be tinted or rendered opaque, leaving the first optical element in the bottom with a clear disposition.
The second optical element is located in the cap. Again, second optical element may take the form of an ocular lens of the double concave or divergent type. Of course, other configurations may be used with the objective and ocular elements found in the bottom and cap, respectively to form other types of telescopes, microscopes or the like. Further, the second optical elements may be imbedded or molded into place in the same manner as the first optical element, hereinabove described. The first and second optical elements would be aligned to allow a user to peer through the first and second optical elements and observe an object adjacent the housing in a magnified state i.e. with an adjusted visual angle.
It should be noted that the cap may have a threaded portion which threadingly engages the threaded portion of the housing at the mouth region. In this manner, the cap possessing the second optical element is adjustable in distance relative to the first optical element in the bottom of the housing. Such adjustment serves as a focus for the optical device of the present invention.
It may be apparent that a novel and useful optical device has been herein above described.
It is therefore an object of the present invention to provide a liquid containing optical device that serves as a container of liquid and as a telescope or microscope when the liquid is removed from the container.
Another object of the present invention is to provide a liquid containing optical device which obviates the need to carry a pair of binoculars, telescope, and the like to an entertainment event.
Another object of the present invention is to provide a liquid containing optical device which prevents the need to dispose of liquid containers formed in a conventional manner.
A further object of the present invention is to provide a liquid containing optical device which is easily transported and concealed for use in either mode.
The invention possesses other objects and advantages especially as concerns particular characteristics and features thereof which will become apparent as the specification continues.
