       BACKGROUND OF THE PRESENT INVENTION 
       [0003]    1. Field of the Present Invention 
         [0004]    The present invention relates generally to the field of waste containment system for storing waste, and, more particularly to a toddler-deterrent containment system for a waste scoop. 
         [0005]    2. Background 
         [0006]    The use of indoor litter boxes to collect pet waste, including feces and urine (sometimes referred to collectively herein as “excrement”), is very well established. Although many people tend to associate cats with using a litter box, there exist various other household pets trained to use a litter box, including, for example, ferrets, rabbits, and even some dogs. The tool most often used to sift through a litter box and remove pet waste from a litter box is commonly referred to as a “litter scoop.” The removal of the feces and urine from a litter scoop is often referred to as “cleaning” the litter box. However, sifting through a litter box with a litter scoop further contaminates all the litter in the litter box with potential disease-causing pathogens. Disease-causing pathogens may include, but are not limited to, bacteria, parasites, fungus, toxoplasmosis,  escherichia coli,  and  salmonella,  all of which have been associated with exposure to animal excrement. 
         [0007]    Certain products are known to be marketed as cat litter scoop retainers, holders, holsters, scoops with removable liners, or containers. For example, U.S. Pat. No. 7,047,907 to Johnston, U.S. Pat. No. 6,976,661 to Lipscomb et al., U.S. Pat. No. 5,782,203 to Tennen, and U.S. Pat. No. 5,460,293 to Erickson each of which disclose a replaceable scoop head, a holder or housing for a cat litter scoop. The scoop may be fully exposed or partially contained within the holder. These known holders may be structured to minimize the release of the odor from the holder. Other holders permit air to pass therethrough to facilitate drying of the waste. However, the structures of such holders afford no means of deterring or prohibiting a toddler or others from unnecessarily touching a contaminated scoop and handle. 
         [0008]    Accordingly, it is believed that a need exists for an improved waste scoop containment system, which is toddler-deterrent. Additionally, it is believed that a need exists for the safe storage of a waste scoop. It is believed that one or more of these needs and other needs are addressed by one or more aspects and features of the present invention.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0025]    As a preliminary matter, it will readily be understood by one having ordinary skill in the relevant art (“Ordinary Artisan”) that the present invention has broad utility and application. Furthermore, any embodiment discussed and identified as being “preferred” is considered to be part of a best mode contemplated for carrying out the present invention. Other embodiments also may be discussed for additional illustrative purposes in providing a full and enabling disclosure of the present invention. Moreover, many embodiments, such as adaptations, variations, modifications, and equivalent arrangements, will be implicitly disclosed by the embodiments described herein and fall within the scope of the present invention. 
         [0026]    Accordingly, while the present invention is described herein in detail in relation to one or more embodiments, it is to be understood that this disclosure is illustrative and exemplary of the present invention, and is made merely for the purposes of providing a full and enabling disclosure of the present invention. The detailed disclosure herein of one or more embodiments is not intended, nor is to be construed to limit the scope of patent protection afforded the present invention, which scope is to be defined by the claims and the equivalents thereof. It is not intended that the scope of patent protection afforded the present invention be defined by reading into any claim a limitation found herein that does not explicitly appear in the claim itself. 
         [0027]    Thus, for example, any sequence(s) and/or temporal order of steps of various processes or methods that are described herein are illustrative and not restrictive. Accordingly, it should be understood that, although steps of various processes or methods may be shown and described as being in a sequence or temporal order, the steps of any such processes or methods are not limited to being carried out in any particular sequence or order, absent an indication otherwise. Indeed, the steps in such processes or methods generally may be carried out in various different sequences and orders while still falling within the scope of the present invention. Accordingly, it is intended that the scope of patent protection afforded the present invention is to be defined by the appended claims rather than the description set forth herein. 
         [0028]    Additionally, it is important to note that each term used herein refers to that which the Ordinary Artisan would understand such term to mean based on the contextual use of such term herein. To the extent that the meaning of a term used herein—as understood by the Ordinary Artisan based on the contextual use of such term—differs in any way from any particular dictionary definition of such term, it is intended that the meaning of the term as understood by the Ordinary Artisan should prevail. 
         [0029]    Furthermore, it is important to note that, as used herein, “a” and “an” each generally denotes “at least one,” but does not exclude a plurality unless the contextual use dictates otherwise. Thus, reference to “a picnic basket having an apple” describes “a picnic basket having at least one apple” as well as “a picnic basket having apples.” In contrast, reference to “a picnic basket having a single apple” describes “a picnic basket having only one apple.” 
         [0030]    When used herein to join a list of items, “or” denotes “at least one of the items,” but does not exclude a plurality of items of the list. Thus, reference to “a picnic basket having cheese or crackers” describes “a picnic basket having cheese without crackers”, “a picnic basket having crackers without cheese”, and “a picnic basket having both cheese and crackers.” Finally, when used herein to join a list of items, “and” denotes “all of the items of the list.” Thus, reference to “a picnic basket having cheese and crackers” describes “a picnic basket having cheese, wherein the picnic basket further has crackers,” as well as describes “a picnic basket having crackers, wherein the picnic basket further has cheese.” 
         [0031]    Referring now to the drawings, in which like numerals represent like components throughout the several views, the preferred embodiments of the present invention are next described.
