The present invention is further illustrated by the following examples, which are not to be construed in any way as imposing limitations upon the scope thereof. On the contrary, it is to be clearly understood that resort may be had to various other embodiments, modifications, and equivalents thereof which, after reading the description herein, may suggest themselves to those skilled in the art without departing from the spirit of the present invention and/or the scope of the appended claims.


EXAMPLE 1
Preparation of Trailer Hitch Attachable Coolers
Exemplary Trailer Hitch Attachable Coolers as Shown in FIGS. 1-11 were Prepared

It should be understood that although the above-described trailer hitch attachable coolers and/or methods are described as “comprising” one or more components or steps, the above-described trailer hitch attachable coolers and/or methods may “comprise,” “consists of,” or “consist essentially of” the above-described components, features or steps of the trailer hitch attachable coolers and/or methods. Consequently, where the present invention, or a portion thereof, has been described with an open-ended term such as “comprising,” it should be readily understood that (unless otherwise stated) the description of the present invention, or the portion thereof, should also be interpreted to describe the present invention, or a portion thereof, using the terms “consisting essentially of” or “consisting of” or variations thereof as discussed below.


As used herein, the terms “comprises,” “comprising,” “includes,” “including,” “has,” “having,” “contains”, “containing,” “characterized by” or any other variation thereof, are intended to encompass a non-exclusive inclusion, subject to any limitation explicitly indicated otherwise, of the recited components. For example, a trailer hitch attachable cooler and/or method that “comprises” a list of elements (e.g., components, features, or steps) is not necessarily limited to only those elements (or components or steps), but may include other elements (or components or steps) not expressly listed or inherent to the trailer hitch attachable cooler and/or method.


As used herein, the transitional phrases “consists of” and “consisting of” exclude any element, step, or component not specified. For example, “consists of” or “consisting of” used in a claim would limit the claim to the components, materials or steps specifically recited in the claim except for impurities ordinarily associated therewith (i.e., impurities within a given component). When the phrase “consists of” or “consisting of” appears in a clause of the body of a claim, rather than immediately following the preamble, the phrase “consists of” or “consisting of” limits only the elements (or components or steps) set forth in that clause; other elements (or components) are not excluded from the claim as a whole.


As used herein, the transitional phrases “consists essentially of” and “consisting essentially of” are used to define a trailer hitch attachable cooler and/or method that includes materials, steps, features, components, or elements, in addition to those literally disclosed, provided that these additional materials, steps, features, components, or elements do not materially affect the basic and novel characteristic(s) of the claimed invention. The term “consisting essentially of” occupies a middle ground between “comprising” and “consisting of”.


Further, it should be understood that the herein-described trailer hitch attachable coolers and/or methods may comprise, consist essentially of, or consist of any of the herein-described components, features and steps, as shown in the figures with or without any feature(s) not shown in the figures. In other words, in some embodiments, the trailer hitch attachable coolers and/or methods of the present invention do not have any additional features other than those shown in the figures, and such additional features, not shown in the figures, are specifically excluded from the trailer hitch attachable coolers and/or methods. In other embodiments, the trailer hitch attachable coolers and/or methods of the present invention do have one or more additional features that are not shown in the figures. For example, although not shown in the figures, the trailer hitch attachable coolers of the present invention may further comprise one or more of the following additional features: a bottle opener positioned along an outer surface (e.g., along a surface of the fishing rod holder, along a surface of the platform such as a rear surface, etc.) of the cooler; a knife and/or pliers holder cut into the fishing rod holder accessory; grab handles molded into the cooler.


While the specification has been described in detail with respect to specific embodiments thereof, it will be appreciated that those skilled in the art, upon attaining an understanding of the foregoing, may readily conceive of alterations to, variations of, and equivalents to these embodiments. Accordingly, the scope of the present invention should be assessed as that of the appended claims and any equivalents thereto.
