Referring to the Figures, the beverage container 1, in accordance with an embodiment of the invention, comprises a substantially cylindrical outer layer 10 and a substantially cylindrical inner layer 30. The outer layer may comprise at least one aperture 20 that may be filled by a transparent window 21. At least a portion of the inner layer may be transparent 31 and may be configured to interlock the inner layer 30 and the outer layer 10 via the transparent window 21.

With respect to the substantially cylindrical outer layer 10, in one embodiment, the outer layer 10 may be made of plastic. Suitable plastics include polycarbonate, polyethylene, polyethylene terephthalate, polypropylene, polystyrene, polyvinyl chloride and mixtures thereof. In other embodiments, the outer layer 10 may be made of glass, aluminum, carbon fiber, stainless steel, ceramic or other suitable material(s). In addition, the outer layer may 10 comprise at least one aperture 20. The aperture(s) 20 may be positioned in various locations in the outer layer 10. Moreover, the size and shape of the aperture(s) 20 may vary. For example, as shown in the Figures, the aperture 20 may be in the shape of an elongated slit extending vertically down a side of the outer layer 10.

Referring to the transparent window 21, in one embodiment, the transparent window 21 may be made of plastic. Suitable plastics include polycarbonate, polyethylene, polyethylene terephthalate, polypropylene, polystyrene, polyvinyl chloride and mixtures thereof. In another embodiment, the transparent window 21 may be made of glass. The transparent window 21 may also vary in size and shape. However, at least a portion of the transparent window 21 should correspond in size and shape to the aperture 20 in the outer layer 10. For example, the transparent window 21 may be in the shape of an elongated rod that extends the same length vertically and same width horizontally as the aperture 20 in the outer layer 10. If desired, the transparent window 21 may be attached to the inside of the outer layer 10 using a suitable adhesive, e.g., glue.

With respect to the substantially cylindrical inner layer 30, in some embodiments, the inner layer 30 may be made of plastic. Representative plastics include polycarbonate, polyethylene, polyethylene terephthalate, polypropylene, polystyrene, polyvinyl chloride and mixtures thereof. In other embodiments, the inner layer 30 may be made of glass, aluminum, carbon fiber, stainless steel, ceramic or other suitable material(s). Whatever material is used, at least a portion of the inner layer 31 may be transparent. The portion of the inner layer that is transparent 31 may vary in shape and size. For example, as shown in the Figures, the portion of the inner layer that is transparent may be in the shape of an elongated bar extending vertically down a side of the inner layer 30. Alternatively, the entire inner layer 30 may be transparent.

In addition, the inner layer 30 may be configured to interlock the inner layer 30 and the outer layer 10 via the transparent window 21. Such a configuration may be achieved in various ways. For example, the inner layer 30 may comprise at least one projection 32 on the outside of the inner layer 30 that may be configured to interlock the inner layer 30 and the outer layer 10 via the transparent window 21 when the beverage container 1 is fully assembled. The configuration of the projection 32 may also vary. For example, the projection 32 may be in a shape similar to that of the transparent window 21 so that the projection 32 fits securely around the outer perimeter of the transparent window 21 when the beverage container 1 is fully assembled. The size and shape of the projection(s) 32 may vary. For example, as shown in FIG. 4, the projection 32 may shaped like an elongated U.

When the beverage container 1 is being assembled, the transparent window 21 may be aligned with a transparent portion 31 of the inner layer 30. This allows for the amount of liquid inside the beverage container to be easily observed from the outside. If the beverage container also comprises a top cover, the top cover may not have to be removed to determine the quantity of liquid in the beverage container. In addition, by not having to remove the top cover, the spilling and splashing of the liquid contained in the beverage container may be minimized.

In one embodiment, at least a portion of the top of the inner layer 33 extends beyond the upper edge of the outer layer 11. In another embodiment, at least a portion of the top of the inner layer extending beyond the upper edge of the outer layer may be configured to engage the upper edge of the outer layer 11. Such a configuration may be achieved in various ways. For example, at least a portion of the top of the inner layer extending beyond the upper edge of the outer layer 33 may comprise a substantially cylindrical peripheral lip 34 configured to engage the upper edge of the outer layer 11. The substantially cylindrical peripheral lip 34 may also be configured in various ways. For instance, the substantially cylindrical peripheral lip 34 may extend out from the inner layer 30 so that the peripheral lip 34 rests on the top of the upper edge of the outer layer 11 when the beverage container 1 is fully assembled.

In one embodiment, the beverage container 1 may further comprise a base cap 40. In another embodiment, at least a portion of the bottom of the inner layer 35 may extend beyond the base edge of the outer layer 12. In some embodiments, at least a portion of the bottom of the inner layer, including the portion that extends beyond the base edge of the outer layer 35, or the outer layer may comprise threads 36 that allow for the base cap 40 and either the inner layer 30 or the outer layer 10 to be joined so as to form a seal between the base cap 40 and the outer layer 10. In other embodiments, the base cap 40 may comprise threads 41 that allow for the base cap 40 and either the inner layer 30 or the outer layer 10 to be joined so as to form a seal between the base cap 40 and the outer layer 10. In still other embodiments, the base cap 40 may snap onto the bottom of either the inner layer 30 or the outer layer 10. To ensure a good seal between the base cap 40 and the outer layer 10, the base cap 40 may include an O-ring. When the beverage container 1 is fully assembled, the O-ring may be positioned between the outer layer 10 and the base cap 40. The base cap 40 may be comprised of any suitable material(s), e.g., plastic. Moreover, the color of the base cap 40 may vary.

In one embodiment, the beverage container 1 may further comprise a removable top cover 50. In another embodiment, at least a portion of the top of the inner layer 33 may comprise threads 37 that allow for the removable top cover 50 and the inner layer 30 to be joined. In another embodiment, the removable cover 50 may have threads 51 that allow for the removable top cover 50 and the inner layer 30 to be joined. In still another embodiment, the removable top cover 50 may snap onto the upper portion of the inner layer 30.

To enable an individual to drink from the covered beverage container, the removable top cover may include a dispensing aperture 52 and a ventilation aperture 53. The removable top cover 50 may also comprise a mechanism that opens and closes the dispensing aperture 52. There are various mechanisms that may be utilized. One example is shown in FIGS. 5 and 6, wherein the mechanism may comprise two pieces, an upper piece 54 and a lower piece 55 which are located on the top and bottom of the removable top cover 50, respectively. To open and close the dispensing aperture 52, the upper piece 54 is manually moved towards or away from the dispensing aperture 52. The lower piece 55 moves with the upper piece 54 and includes a portion 56 that slides to either open or close the dispensing aperture 52. The aforementioned features may make the beverage container more suitable for carrying around and help prevent the spilling of the liquids inside the beverage container. Like the base cap 40, the removable top cover 50 may be comprised of any suitable material(s), e.g., plastic. Moreover, as with the base cap 40, the color of the removable top cover 50 may vary. The ability to vary the color of the base cap 40 and/or the removable top cover 50 may make the beverage container more aesthetically pleasing and/or allow for the matching of the color scheme of the beverage container to a business' logo.

In some embodiments, an ornamental design may be applied to either or both the inner layer 30 and the outer layer 10. The design may be applied using any suitable technique, e.g., silk-screening. Furthermore, the design may be comprised of one or more portions. Suitable ornamental designs include business logos, pictures, phrases and drawings.

In other embodiments, the beverage container 1 may further comprise a grip structure. Various grip structures may be utilized. One example is a plastic or leather piece attached to the outside of the outer layer 10. By attaching a plastic or leather piece to the outside of the outer layer 10, an individual may be able to more easily the grab and hold the beverage container. Suitable plastics include polycarbonate, polyethylene, polyethylene terephthalate, polypropylene, polystyrene, polyvinyl chloride and mixtures thereof. The position, size, shape and color of the piece(s) may vary. In addition, the piece(s) may be adhered to the outside of the outer layer 10 using a suitable adhesive, e.g., glue. Alternatively, the outer layer 10 itself may be manufactured to include a raised ridge that would function as a grip structure. The grip structure may also be a handle attached to the beverage container.
