     BACKGROUND OF THE PRESENT INVENTION 
     1. Field of the Present Invention 
     The present invention relates generally to edible animal medicine containers, and in particular, to edible animal medicine containers that seal or partially seal a designated quantity of medicine or other ingestible material inside. 
     2. Background 
     A problem encountered by nearly pet owner and many other animal caretakers is the administration of oral medications and other ingestible materials to an animal. Animals frequently object to the taste, smell, texture, or the like of the material, or are generally distrustful of the person administrating the material or the manner in which it is administered. 
     A variety of techniques have been utilized to accomplish such administration. Simple techniques include disguising the pill or other material within a food that the animal is known to eat readily. For example, many dog and/or cat owners have hidden pills within a serving of peanut butter or rolled or buried within a slice of cheese or meat. 
     For administration of liquid medicines to animals, there are various syringes, spoons, sprayers and the like that are inserted into the animal&#39;s mouth and used to squirt or dispense such liquids into the animal&#39;s mouth. Unfortunately, animals tend to dislike these approaches for many reasons, including the feeling of being force fed, the taste of the medicine being dispensed, and the smell of the medicine. 
     More recently, edible food containers or carriers have been developed for such a purpose. Examples of such containers or carriers are describe, for example, in U.S. Pat. No. 5,792,470 (issued Aug. 11, 1998 to Baumgardner, Sr. and titled “EDIBLE CONTAINER FOR ADMINISTERING MEDICATION TO ANIMALS”), U.S. Pat. No. 6,143,316 (issued Nov. 7, 2000 to Hayden et al and titled “DIGESTIBLE POUCH AND METHOD FOR ADMINISTERING MEDICATIONS TO AN ANIMAL”), U.S. Pat. No. 8,501,218 (issued Aug. 6, 2013 to Hurwitz and titled “EDIBLE CHEW PILL JACKET”), and U.S. Patent Publication No. US2011/0256208 A1 (issued Oct. 20, 2011 to Ling and titled “EDIBLE CARRIER FOR ANIMAL MEDICATION”), each of which is incorporated its entirety by reference and a copy of each of which is attached hereto as an appendix. However, these devices suffer from various shortcomings, including inability to disguise or contain the smell of the pills or medicine contained therein, inability to assist in measuring a volume or quantity of medicine or other material, not being watertight or water sealed, and the like. Smell, in particular, has recently gained notice as a significant factor in whether an animal such as a dog or cat is willing to ingest a particular medicine, pill or other substance, as a dog&#39;s sense of smell is upwards of 40 times as acute as a human&#39;s, and non-watertight or water sealed containers fail to potentially prevent a dog from being able to pick up the scent of medicines or other ingestible materials disposed inside. 
     Thus, a need exists for further improvement in edible animal medicine containers, such as but not limited to means for easier measuring and loading.

     DETAILED DESCRIPTION 
     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. As should be understood, any embodiment may incorporate only one or a plurality of the above-disclosed aspects of the invention and may further incorporate only one or a plurality of the above-disclosed features. 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. 
     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. 
     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. 
     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. 
     Regarding applicability of 35 U.S.C. §112, ¶6, no claim element is intended to be read in accordance with this statutory provision unless the explicit phrase “means for” or “step for” is actually used in such claim element, whereupon this statutory provision is intended to apply in the interpretation of such claim element. 
     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.” 
     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.” 
     Referring now to the drawings, in which like numerals represent like components throughout the several views, one or more preferred embodiments of the present invention are next described. The following description of one or more preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses. 
       FIG. 1  is a perspective view of a man  12  feeding medicine or other ingestible material contained in an edible animal medicine container  10  to a pet  14  in accordance with one or more preferred embodiments of the present invention. The container  10  serves as a delivery device or mechanism for an ingestible material contained inside. The ingestible material may be a medicine, drug, pharmaceutical, vitamin, supplement, herb, x-ray dye, butter, paste, gel, powder, or the like. The medicine may be in the form of a hard (e.g. pill) or soft (e.g. paste, gel, or the like) solid, a liquid, a powder material, a granular material, or the like, and the container  10  may be flavored, scented, colored, and/or otherwise designed to appeal to a pet. As described below, the container  10  thus provides an effective way to ensure and encourage the ingestion of the medicine, in whatever form, by a pet or other animal. 
       FIG. 2  is a perspective view of an edible pet medicine container  10  of the type shown in  FIG. 1 , shown in a closed configuration, and  FIG. 3  is a perspective view of the edible pet medicine container  10  of  FIG. 2 , shown in a partially open configuration. As shown therein, the container  10  includes a housing  20 , defining an interior  16 , and a hinge or tether  30 . The housing  20  includes an upper shell  22  and a lower shell  24 , which at least for convenience may be referred to herein as an upper half and a lower half. The housing halves are shaped such that when closed, the housing is somewhat egg-shaped. The rounded exterior of such housing shape advantageously avoids corners and edges that might be unappealing to the animal ingesting the container  10 , but it will be appreciated that other shapes, including simple shapes, such as spherical, oblong, pill-shaped, or the like, and complex shapes, such as “bone”-shaped, animal-shaped (full scale or miniature, and including a cat shape, a bird shape, a rabbit shape, a squirrel shape, and/or a bear shape) may alternatively be utilized. The exterior surface of the housing  20  may be smooth or rough, and/or may have contours and texturing that mimics various other materials. For example, in various embodiments, the exterior surface of the housing  20  may mimic wood grain, corn kernels, pine cone or walnuts. In this regard, the shape of the housing  20  may be selected to match the texture, so that the overall container resembles an object such as a pine cone, a walnut, or any of various types of seeds. 
       FIG. 4  is a side cross-sectional view of the edible pet medicine container  10  of  FIG. 2 . As shown therein, the two halves  22 , 24  are designed to be interlocked or otherwise coupled together so as to provide a closed, sealed or semi-sealed interior in which medicines, vitamins, or other materials may be filled, loaded or otherwise disposed for ingestion by an animal. For example,  FIG. 5  is a side cross-sectional view of the edible pet medicine container  10  of  FIG. 2 , shown with a pill  18  disposed inside. Such an interlock or coupling advantageously prevents or discourages the container  10  from being opened while it is still in the animal&#39;s mouth (i.e., before it has been swallowed). It advantageously also serves to deter the animal from eating only the container  10  and spitting out the pill or medicine contained inside. 
     A variety of structures may be used to interlock or otherwise couple the two halves  22 , 24  together. The connection established between the two halves  22 , 24  is preferably strong enough to maintain the two halves  22 , 24  in the closed configuration until the container  10  is safely placed in the mouth of the animal  14 , and more preferably is strong enough to maintain the two halves  22 , 24  in the closed configuration until the animal  14  swallows the container  10 . One set of structures achieving such a connection is illustrated in  FIGS. 4-8 , wherein  FIG. 6  is a side cross-sectional view of the edible pet medicine container  10  of  FIG. 4 , shown in an open configuration;  FIG. 7  is an enlarged, fragmentary side cross-sectional view of the edible pet medicine container  10  of  FIG. 6 ; and  FIG. 8  is a side view of the edible pet medicine container  10  of  FIG. 2 , shown in a fully open configuration. As shown therein, a rim  32  of the upper half  22  is shaped and sized so as to fit within a rim  34  of the lower half  24  when the two halves  22 , 24  are manipulated from the open configuration to the closed configuration. When fully closed, the rim  32  of the upper half  22  is seated on a ledge  38  within the rim  34  of the lower half  24 , and the rim  34  of the lower half  24  is seated against a ledge  36  around the rim  32  of the upper half  22 . The respective rims and ledges are thereby coupled together and retained in place via snap fit, friction fit, or the like. 
     The hinge or tether  30  permits the two halves  22 , 24  to be separated but kept close together so as to avoid dropping, losing or misplacing one of the halves while manipulating the other one. In at least some embodiments, the hinge may also provide assistance in holding the two halves together when placed in the closed configuration, and/or the hinge may also provide assistance in guiding the two halves together when manipulating the halves from the open configuration into the closed configuration. In at least some embodiments, the hinge or tether  30  is a living hinge that is flexible enough to provide a hinge function without degrading while the medicine or other ingestible is being loaded into the container  10  and administered to the animal  14 . 
     In at least some embodiments, the container  10 , including the housing halves  22 , 24  and the hinge or tether  30 , is constructed from an edible base, such as a potato-based food material. The edible base is produced in the form of a hard or semi-hard shell structure created from a mixture. An appropriate mixture may be created and molded or otherwise formed into the desired shape and baked or allowed to dry according to conventional food preparation processes. The shell structure can be made via various high-volume food manufacturing processes such as molding, injection molding, stamping and the like. The hinge or tether  30  may be formed as part of the housing  20  or may be formed separately and added to the hinge halves  22 , 24 . Additives, including preservatives, seasonings, and flavorings, may be added to the mixture, surface-coated onto the hardened shell, or the like. In one particular embodiment, the housing  20  is naturally or artificially bacon-flavored, beef flavored or chicken flavored. 
     As noted previously, the container  10  may preferably accept medicines and other animal-edible materials in various forms, including pill or other solid form, powder or granular form, liquid form, gel form, paste form, and the like. For example,  FIG. 5  illustrated the disposition of a single pill  18  within a container  10 . As another example,  FIG. 9  is a side perspective view of an alternative edible pet medicine container  110 , in accordance with one or more preferred embodiments of the present invention, shown being loaded with a medicine  118  or other ingestible in liquid form, and  FIG. 10  is a side perspective view of the edible pet medicine container  110  of  FIG. 9 , shown being closed. As shown in  FIGS. 9 and 10 , the container  110  includes a housing  120 , defining an interior  116 , and a hinge or tether  130 . The housing  120  includes an upper shell  122  and a lower shell  124 , which at least for convenience may be referred to herein as an upper half and a lower half. In some embodiments, the housing  120  and hinge or tether  130  are of similar construction to the housing  20  and hinge or tether  30  of  FIGS. 1-8 , but in at least some embodiments, the housing  120  may be designed to hold a liquid  118 , without dripping or soaking through, for at least a period of time sufficient to facilitate filling the lower half  124  and safe placement of the container  110  the mouth of the animal  14 . Preferably, however, the housing  120  is still able to dissolve quickly once the container  110  enters the animal&#39;s digestive tract. In  FIG. 9 , the container  110  is shown with an appropriate amount of a liquid medicine  118  being measured out and poured or dripped into at least one half  124  thereof, and in  FIG. 10 , the container  110  is shown being closed by rotating the upper half  122  up and over the top of the lower half  124 , enclosing the liquid  118  therein. 
     In at least some embodiments, one or both halves of a container have a volumetric capacity of a standard predetermined size so as to facilitate measurement of a desired volume of medicine or other ingestible material. For example, each half  122 , 124  of the container  110  of  FIGS. 9 and 10  may be sized to receive a tablespoon of liquid, powder, granular, or soft solid material. In some embodiments, the two halves may not be equal in size, and each “half” is sized to accommodate a different predetermined volume. For example,  FIGS. 11 and 12  are side cross-sectional views of another alternative edible pet medicine container  220  in accordance with one or more preferred embodiments of the present invention, wherein the left or top shell or half  222  has a capacity of one U.S. teaspoon while the right or bottom shell or half  224  has a capacity of one U.S. tablespoon. Furthermore, in some embodiments, one or both halves may include subdivided markings to make it possible to fill such half to a known quantity other than the full amount. For example, in  FIGS. 11 and 12 , the right or bottom half  224 , which has a one tablespoon capacity, also has markings subdividing the overall capacity into one and two teaspoon increments. It will be appreciated, however, that other measurement increments and scales may additionally or alternatively be utilized without departing from the scope of the present invention. Such increments and scales may include, without limitation, milliliters, culinary units, weights (e.g., grams), and the like. 
       FIG. 13  is a perspective view of another alternative edible pet medicine container  310  in accordance with one or more preferred embodiments of the present invention, and  FIG. 14  is a side view of the edible pet medicine container  310  of  FIG. 6 . As shown therein, the container  310  includes a housing  320 , defining an interior  316 , and a hinge or tether  330 . The housing  320  includes an upper shell  322  and a lower shell  324 , which at least for convenience may be referred to herein as an upper half and a lower half. The container  310  of  FIG. 13  also includes a latch  340  for holding the two halves  322 , 324  together. The latch  340  includes a prong  342  on the upper half  322  and a receptacle  344  on the lower half  324 , wherein the prong  342  may be forced into the receptacle  344  and retained there via snap fit, friction fit, or the like. Like the other portions of the container  310 , the latch  340  is made from an edible base. It will be appreciated that other latch types may be substituted for the latch  340  shown in  FIGS. 13 and 14 . Such latch types may include, without limitation, rivets, one-way snaps, locking closures, and the like. Such a latch or locking mechanism advantageously prevents or discourages the container  310  from being opened while it is still in the animal&#39;s mouth (i.e., before it has been swallowed). It advantageously also serves to deter the animal  14  from eating only the container  310  and spitting out the pill or medicine contained inside. 
       FIG. 15  is a perspective view of another alternative edible pet medicine container  410  in accordance with one or more preferred embodiments of the present invention. As shown therein, the container  410  takes the shape of a bone, although such shape need not be anatomically correct. Furthermore, the bone shape is only representative; the shape of the container may be of any desired shape, designed for the purposes herein. As shown in  FIG. 15 , the container  410  includes a housing  420 , defining an interior  416 , and a hinge or tether  430 . The housing  420  includes a left portion  422  and a right portion  424 , which at least for convenience may be referred to herein as a left half and a right half. In addition to having a unique shape, the container  410  of  FIG. 15  also incorporates a threaded design for holding the two halves  422 , 424  together. In particular, a hollow male portion  434 , having exterior threads  444 , extends from the right half  424 , while a female portion  432 , having interior threads (not visible), forms a part of the left half  422 . Once one or both of the halves  422 , 424  are filled with medicine or other ingestible material, they may be screwed together to retain the medicine inside. Such a threaded connection system advantageously prevents or discourages the container  410  from being opened while it is still in the animal&#39;s mouth (i.e., before it has been swallowed). It advantageously also serves to deter the animal  14  from eating only the container  410  and spitting out the pill or medicine contained inside. As with the other containers, all of the components of this container  410  may be made from an edible base. 
       FIG. 16  is a perspective view of another alternative edible pet medicine container  510  in accordance with one or more preferred embodiments of the present invention. As shown therein, the container  510  includes a housing  520 , defining an interior  516 , and a hinge or tether  530 . The housing  520  includes an upper shell  522  and a lower shell  524 , which at least for convenience may be referred to herein as an upper half and a lower half. The hinge or tether  530  of the container  510  of  FIG. 16  takes the form of a neck or bridge that may or may not be flexible, but which may be easily broken to permit the upper half  522  to be manipulated into place on the lower half  524 , as shown in  FIG. 17 , and the closed container  510 , with the medicine inside it, may be fed or otherwise administered to the animal  14  as shown in  FIG. 18 . As with the other containers, all of the components of this container  510  may be made from an edible base. The two halves  522 , 524  may utilize any of the coupling or connection structures described herein, or may use other conventional coupling or connection structures to facilitate the halves  522 , 524  being coupled together. 
       FIGS. 19 and 20  are a perspective view and a side view, respectively, of another alternative edible pet medicine container  610 , shown in a closed state, in accordance with one or more preferred embodiments of the present invention;  FIGS. 21 and 22  are a bottom perspective view and top perspective view, respectively, of the edible pet medicine container  610  of  FIG. 19 , shown in an open state; and  FIGS. 23 and 24  are a bottom view and a top view, respectively, of the edible pet medicine container  610  of  FIG. 21 . As shown therein, the container  610  includes a housing  620 , defining an interior  616 , and a hinge or tether  630 . The housing  620  includes an upper shell  622  and a lower shell  624 , which at least for convenience may be referred to herein as an upper half and a lower half. As perhaps best illustrated in  FIG. 22 , the open face of each half  622 , 624  has a respective peripheral ledge  632 , 634  and a central hollow  626 , 628 . Surrounding the central hollow  626  of the upper half  622 , but interior from the peripheral ledge  632 , is a recessed ledge  636 , while surrounding the central hollow  628  of the lower half  624 , but interior from the peripheral ledge  634 , is a standing wall or higher-level ledge  638 . The various ledges are shaped and sized to fit together as described below. 
       FIG. 25  is an end cross-sectional view of the edible pet medicine container  610  of  FIG. 22 , taken along line  25 - 25 ;  FIG. 26  is an enlarged fragmentary portion of the edible pet medicine container  610  of  FIG. 25 . The various ledges may be seen more clearly in  FIG. 25 , with some additional detail visible in  FIG. 26 . The two halves  622 , 624  may be fit together as shown in  FIG. 27 , which is a side cross-sectional view of the edible pet medicine container  610  of  FIG. 19 , taken along line  27 - 27 . As shown therein, the standing wall or higher-level ledge  638  of the lower half  624  fits neatly into the recessed ledge  636  on the upper half  622 , with the peripheral ledges  632 , 634  meeting one another. In this closed state, the central hollows  626 , 628  together form an interior  616 . 
     Due to the slightly flexible nature of the material from which the two halves  622 , 624  are made, the respective ledges are thereby coupled together and retained in place via friction fit, thereby providing a closed and sealed or semi-sealed interior in which medicines, vitamins, or other materials may be filled, loaded or otherwise disposed for ingestion by an animal  14 . For example,  FIG. 28  is a side cross-sectional view of the edible pet medicine container  610  of  FIG. 27 , shown with a pill  18  loaded inside. Such an interlock or coupling advantageously prevents or discourages the container  610  from being opened while it is still in the animal&#39;s mouth (i.e., before it has been swallowed). It advantageously also serves to deter the animal  14  from eating only the container  610  and spitting out the pill or medicine contained inside. 
     Notably, the peripheral ledges  632 , 634  of the upper and lower halves  622 , 624  are each flared outward relative to the rest of the body of the respective shell  622 , 624 . This may perhaps be best seen in the profile views shown in  FIGS. 20 and 25-28 . Such flaring provides additional surface area for the ledges  632 , 634  and thus additional areas of contact (and perhaps better sealing) between such ledges, provides additional thickness for the walls of the shells  622 , 624  and thus additional width or thickness (and greater strength) to the various ledges, and provides additional contouring (and thus makes the exterior shape less artificial, more organic, and more appealing to a target animal) to the exterior of the container  610 . 
     Because the two halves  622 , 624  are of slightly different design (e.g., the upper half  622  has a recessed ledge  636 , while the lower half  624  has a standing ledge  638 ), it is necessary for each container  610  to utilize one upper half  622  and one lower half  624 . The hinge  630  helps the user  12  avoid fumbling for a pair of matching halves  622 , 624  by clearly linking together one upper half  622  and one lower half  624 . The hinge  630 , as well as the two halves  622 , 624 , may be made of materials similar to those of other halves and hinges or tethers described herein. Further, because the two halves  622 , 624  create a sealed or semi-sealed interior  616  when coupled together, this container  610  may be utilized to hold a liquid, such as a liquid medicine, in a manner similar to that of the container  110  of  FIGS. 9 and 10 . Furthermore, at least one half (such as the lower half  624  as perhaps best shown in  FIG. 24 ) may be labeled with the effective volume of the container  610  for purposes of facilitating precise dosing. This may be accomplished, for example, by embossing, stamping, or otherwise marking one or both of the halves  622 , 624  on their interior or exterior. In the embodiment of  FIGS. 19-28 , the interior of the lower half  624  has been embossed with the label “1 TSP” to indicate that the central hollow of the lower shell  624  has a volume of one teaspoon. 
       FIGS. 29 and 30  are a perspective view and a side view, respectively, of another alternative edible pet medicine container  710 , shown in a closed state, in accordance with one or more preferred embodiments of the present invention; and  FIGS. 31 and 32  are a bottom perspective view and a top perspective view, respectively, of the edible pet medicine container  710  of  FIG. 29 , shown in an open state. As shown therein, the container  710  includes a housing  720 , defining an interior  716 , that includes an upper shell  722  and a lower shell  724 , which at least for convenience may be referred to herein as an upper half and a lower half. As perhaps best illustrated in  FIG. 32 , the open face of each half  722 , 724  has a respective peripheral ledge  732 , 734  and a central hollow  726 , 728 . A recessed ledge or slot  736  is arranged in the peripheral ledge  732 , 734  along one lateral side of each half  722 , 724 , while a corresponding standing wall or ledge  738  is disposed on the peripheral ledge  732 , 734  along the opposite lateral side of each half  722 , 724 . The cross-section of the standing wall or ledge  738  is similar to that of the recessed ledge or slot  736  such that the standing wall or ledge  738  of the upper half  722  may be fit snugly inside the recessed ledge or slot  736  of the lower half  724 , and such that the standing wall or ledge  738  of the lower half  724  may be fit snugly inside the recessed ledge or slot  736  of the upper half  722 . In this regard,  FIG. 33  is an end cross-sectional view of the edible pet medicine container  710  of  FIG. 32 , taken along line  33 - 33 . As shown therein, the standing wall or ledges  738  fit neatly into the recessed ledges or slots  736  with the peripheral ledges  732 , 734  meeting one another. In this closed state, the central hollows  726 , 728  together form an interior  716 . 
     Due to the slightly flexible nature of the material from which the two halves  722 , 724  are made, the respective ledges are thereby coupled together and retained in place via friction fit, thereby providing a closed and sealed or semi-sealed interior in which medicines, vitamins, or other materials may be filled, loaded or otherwise disposed for ingestion by an animal  14 . For example,  FIG. 34  is a side cross-sectional view of the edible pet medicine container  710  of  FIG. 33 , shown with a pill  18  loaded inside. Such an interlock or coupling advantageously prevents or discourages the container  710  from being opened while it is still in the animal&#39;s mouth (i.e., before it has been swallowed). It advantageously also serves to deter the animal  14  from eating only the container  710  and spitting out the pill or medicine contained inside. 
     Notably, the peripheral ledges  732 , 734  of the upper and lower halves  722 , 724  are each flared outward relative to the rest of the body of the respective shell  722 , 724 . This may perhaps be best seen in the profile views shown in  FIGS. 29, 33, and 34 . Such flaring provides additional surface area for the ledges  732 , 734  and thus additional areas of contact (and perhaps better sealing) between such ledges, provides additional thickness for the walls of the shells  722 , 724  and thus additional width or thickness (and greater strength) to the various ledges, and provides additional contouring (and thus makes the exterior shape less artificial, more organic, and more appealing to a target animal) to the exterior of the container  710 . 
     Because the two halves  722 , 724  are of identical design (e.g., the upper half  722  has a recessed ledge  736  along one side and a standing wall  738  along the other side, and the lower half  724  likewise has a recessed ledge  736  along one side and a standing wall  738  along the other side), it is not necessary to distinguish upper halves  722  from lower halves  724 . Thus, although it may be useful for other purposes, it is not necessary to tether the upper half  722  to the lower half  724  to make it easier for a user  12  to find matching halves  722 , 724 . 
     In at least some embodiments, because the two halves  722 , 724  create a semi-sealed interior  716  when coupled together, this container  710  may be utilized to hold a liquid, such as a liquid medicine, in a manner similar to that of the container  110  of  FIGS. 9 and 10 . 
       FIGS. 35 and 36  are a bottom perspective view and top perspective view, respectively, of another alternative edible pet medicine container  810 , shown in an open state, in accordance with one or more preferred embodiments of the present invention; and  FIG. 37  is an end cross-sectional view of the edible pet medicine container  810  of  FIG. 36 , taken along line  37 - 37 . 
     As shown therein, the container  810  includes a housing  820 , defining an interior  816 , and a connective structure  830 . The housing  820  includes an upper shell  822  and a lower shell  824 , which at least for convenience may be referred to herein as an upper half and a lower half. As perhaps best illustrated in  FIG. 36 , the open face of each half  822 , 824  has a respective peripheral ledge  832 , 834  and a central hollow  826 , 828 . Surrounding the central hollow  826  of the upper half  822 , but interior from the peripheral ledge  832 , is a recessed ledge  836 , while surrounding the central hollow  828  of the lower half  824 , but interior from the peripheral ledge  834 , is a standing wall or higher-level ledge  838 . The various ledges are shaped and sized to fit together as described below. 
     The construction of this container  810  is very similar to that of the container of  FIGS. 19-28  except that the two halves  822 , 824  may be initially provided in a connected state, wherein an edge of the upper half  822  is integrally attached directly to an edge of the lower half  824  via the connective structure  830  rather than a more clearly defined hinge or tether. This connective structure  830  may be a rigid or semi-rigid connection that may easily be snapped and/or broken by a user  12  to enable the two halves  822 , 824  to be fitted together in a manner similar to that shown in  FIG. 27 . In this state, the standing wall or higher-level ledge  838  of the lower half  824  fits neatly into the recessed ledge  836  on the upper half  822 , with the peripheral ledges  832 , 834  meeting one another. In this closed state, the central hollows  826 , 828  together form an interior. 
     Due to the slightly flexible nature of the material from which the two halves  822 , 824  are made, the respective ledges are thereby coupled together and retained in place via friction fit, thereby providing a closed and sealed or semi-sealed interior in which medicines, vitamins, or other materials may be filled, loaded or otherwise disposed for ingestion by an animal  14 . Such an interlock or coupling advantageously prevents or discourages the container  810  from being opened while it is still in the animal&#39;s mouth (i.e., before it has been swallowed). It advantageously also serves to deter the animal  14  from eating only the container  810  and spitting out the pill or medicine contained inside. 
     Notably, the peripheral ledges  832 , 834  of the upper and lower halves  822 , 824  are each flared outward relative to the rest of the body of the respective shell  822 , 824 . Such flaring provides additional surface area for the ledges  832 , 834  and thus additional areas of contact (and perhaps better sealing) between such ledges, provides additional thickness for the walls of the shells  822 , 824  and thus additional width or thickness (and greater strength) to the various ledges, and provides additional contouring (and thus makes the exterior shape less artificial, more organic, and more appealing to a target animal) to the exterior of the container  810 . 
     Because the two halves  822 , 824  are of slightly different design (e.g., the upper half  822  has a recessed ledge  836 , while the lower half  824  has a standing ledge  838 ), it is necessary for each container  810  to utilize one upper half  822  and one lower half  824 . The structural connection  830  helps the user  12  avoid fumbling for a pair of matching halves  822 , 824  by clearly linking together one upper half  822  and one lower half  824 . However, unlike the container  610  of  FIGS. 19-28 , this container  810  lacks a distinct hinge or tether structure, which may help avoid the creation of a sharp or otherwise uncomfortable edge or structure that might otherwise bother an animal  14  that consumes it. The structural connection  830 , as well as the two halves  822 , 824 , may be made of materials similar to those of other halves, hinges and tethers described herein. Further, because the two halves  822 , 824  create a sealed or semi-sealed interior when coupled together, this container  810  may be utilized to hold a liquid, such as a liquid medicine, in a manner similar to that of the container  110  of  FIGS. 9 and 10 . Furthermore, at least one half may be labeled with the effective volume of the container  810  for purposes of facilitating precise dosing. 
       FIG. 38  is a top perspective view of another alternative edible pet medicine container  910 , shown in an open state, in accordance with one or more preferred embodiments of the present invention, while  FIGS. 39 and 40  are a side view and a top view, respectively, of the edible pet medicine container  910  of  FIG. 38 . 
     As shown therein, the container  910  includes a housing  920 , defining an interior  916 , and a connective structure  930 . The housing  920  includes an upper shell  922  and a lower shell  924 , which at least for convenience may be referred to herein as an upper half and a lower half. The open face of each half  922 , 924  has a respective peripheral ledge  932 , 934  and a central hollow  926 , 928 . Spaced around the central hollow  926  of the upper half  922  are a series of cylindrical recesses (recessed ledges)  936  extending into the peripheral ledge  932 , while surrounding the central hollow  928  of the lower half  924  are a series of cylindrical pegs (higher-level ledges)  938  extending or standing from the surface of the peripheral ledge  934 . The various ledges are shaped and sized to fit together as described below. 
     Other than the arrangement of the ledges  936 , 938 , the construction of this container  910  is very similar to that of the container  810  of  FIGS. 35-37 . The two halves  922 , 924  may be initially provided in a connected state, wherein an edge of the upper half  922  is integrally attached directly to an edge of the lower half  924  via the connective structure  930  rather than a more clearly defined hinge or tether. This connective structure  930  may be a rigid or semi-rigid connection that may easily be snapped and/or broken by a user  12  to enable the two halves  922 , 924  to be fitted together in a manner similar to that shown in  FIG. 27 . In this state, the pegs or higher-level ledges  938  of the lower half  924  fit neatly into the recesses or recessed ledges  936  in the upper half  922 , with the peripheral ledges  932 , 934  meeting one another. In this closed state, the central hollows  926 , 928  together form an interior. 
     Due to the slightly flexible nature of the material from which the two halves  922 , 924  are made, the respective ledges are thereby coupled together and retained in place via friction fit, thereby providing a closed and sealed or semi-sealed interior in which medicines, vitamins, or other materials may be filled, loaded or otherwise disposed for ingestion by an animal  14 . Such an interlock or coupling advantageously prevents or discourages the container  910  from being opened while it is still in the animal&#39;s mouth (i.e., before it has been swallowed). It advantageously also serves to deter the animal  14  from eating only the container  910  and spitting out the pill or medicine contained inside. 
     Notably, the cylindrical recesses and pegs  936 , 938  of the upper and lower halves  922 , 924  represent just one of a variety of interlocking features that may be utilized to couple and hold the upper and lower halves  922 , 924  together. A larger or smaller number of recesses and pegs  936 , 938  may be utilized, or the shape of the recesses and pegs  936 , 938  may be varied. 
     Because the two halves  922 , 924  are of slightly different design (e.g., the upper half  922  has a plurality of recesses or recessed ledges  936 , while the lower half  924  has a plurality of pegs or standing ledges  938 ), it is necessary for each container  910  to utilize one upper half  922  and one lower half  924 . The structural connection  930  helps the user  12  avoid fumbling for a pair of matching halves  922 , 924  by clearly linking together one upper half  922  and one lower half  924 . However, unlike the container  610  of  FIGS. 19-28 , this container  910  lacks a distinct hinge or tether structure, which may help avoid the creation of a sharp or otherwise uncomfortable edge or structure that might otherwise bother an animal  14  that consumes it. The structural connection  930 , as well as the two halves  922 , 924 , may be made of materials similar to those of other halves, hinges and tethers described herein. Further, because the two halves  922 , 924  create a sealed or semi-sealed interior when coupled together, this container  910  may be utilized to hold a liquid, such as a liquid medicine, in a manner similar to that of the container  110  of  FIGS. 9 and 10 . Furthermore, at least one half may be labeled with the effective volume of the container  910  for purposes of facilitating precise dosing. 
       FIG. 41  is a perspective view of another alternative edible pet medicine container  1010 , shown in an open state, in accordance with one or more preferred embodiments of the present invention, while  FIGS. 42 and 43  are an end view and a top view, respectively, of the edible pet medicine container  1010  of  FIG. 41 . As shown therein, the container  1010  includes two shells or halves  1022 , 1024  that are integrated with one another or connected together to create an interior  1016  that is accessible only via a temporary gap opening  1013 . The interior  1016  is large enough to accommodate a pill  18  or other ingestible material therein. The container halves  1022 , 1024  are produced in such a way as to be softer and more flexible than in some other embodiments such that the halves  1022 , 1024  may be squeezed, pinched, clamped or otherwise adjusted relative to each other to close the gap opening  1013  and entrap the pill  18  or other ingestible material inside. In this regard,  FIG. 44  is a perspective view of the edible pet medicine container  1010  of  FIG. 41 , shown in a closed state. In at least some of these embodiments, squeezing or otherwise adjusting the halves  1022 , 1024  further creates at least a temporary water seal to prevent liquid medicine or the like from leaking out. 
       FIG. 45  is a perspective view of another alternative edible pet medicine container  1110 , shown in a closed state, in accordance with one or more preferred embodiments of the present invention, while  FIG. 46  is an end view of the edible pet medicine container  1110  of  FIG. 45 . As shown therein, the container  1110  includes two shells or halves  1122 , 1124  that are integrated with one another or connected together to create an interior  1116  (shown in  FIG. 47 ) that is accessible only via a temporary gap opening  1113  that is initially provided in a closed state. The interior  1116  is large enough to accommodate a pill  18  or other ingestible material therein. The container halves  1122 , 1124  are produced in such a way as to be softer and more flexible than in some other embodiments, but more resilient than the container  1010  of  FIGS. 41-44 , such that ends  1123 , 1125  of the container  1110  may be squeezed, pinched, clamped or otherwise adjusted relative to each other to force the gap opening  1113  to pop open and remain open for as long as force continues to be applied. In this regard,  FIG. 47  is a perspective view of a user  12  squeezing the edible pet medicine container  1110  of  FIG. 45  into an open state. As shown therein, a pill  18  has been inserted through the gap opening  1113  so as to be carried in the interior  1116  of the container  1110 . Once the ends  1123 , 1125  are released, the container  1110  is biased to return to its initial state, as shown in  FIG. 45 , thereby entrapping the pill  18  or other ingestible material inside. 
       FIG. 48  is a side view of another alternative edible pet medicine container  1210 , shown in an initial state, provided in the shape of a whimsical character in accordance with one or more preferred embodiments of the present invention. Functionally, the container  1210  of  FIG. 48  is somewhat similar to the container  810  of  FIGS. 35-37 , wherein two shells  1222 , 1224  are initially connected along one side but may be broken apart and maneuvered relative to one another to enclose a pill  18  or other ingestible material inside. In this regard,  FIG. 49  is a side view of the edible pet medicine container  1210  of  FIG. 48 , shown in a separated state, while  FIG. 50  is a perspective view of the edible pet medicine container  1210  of  FIG. 49 , shown in a closed state. Notably, however, the container  1210  of  FIGS. 48-50  is rendered in a whimsical shape, such as that of the head of a cartoon cat or other figure. Such an arrangement may aid in marketing efforts, consumer adoption, or the like. 
     In at least some embodiments, such as the embodiment of  FIGS. 29-34 , the upper and lower halves are of substantially the same size, while in other embodiments, such as the embodiment of  FIGS. 11 and 12 , the upper and lower shells are of unequal size. In some of these embodiments, the upper and lower shells have different sizes to accommodate different dosage amounts, but different sizes could be used for other purposes as well. In at least some commercial embodiments, edible pet medicine containers may be made commercially available in different sizes for different purposes, such as facilitating the measurement of different dosage amounts, providing different sizes for different size animals  14 , or to imitate different types of pet food or edible pet treats. In some of these commercial embodiments, edible pet medicine containers of different sizes are provided in a single package, while in other commercial embodiments, each package contains edible pet medicine containers of only a single size. 
     In at least one contemplated commercial embodiment, an edible pet medicine container is supplied in the form shown in  FIGS. 19-28  and/or the form shown in  FIGS. 29-34 . Such a container may be approximately 1.3 inches long, 0.75 inches wide, with raised walls or ledges and recessed ledges that are approximately 0.075 inches tall or deep, and each half has a volume of one teaspoon. If the container is supplied in the form shown in  FIGS. 19-28 , the hinge may be approximately 0.20 inches wide, approximately 0.25 inches long, and approximately 0.04 inches thick. 
     One material suitable for use as the base material for the construction of the containers described herein is BEP 100 , available from Biosphere Industries, LLC of Carpinteria, Calif. BEP 100  is a high performance, starch-based molding material that can be baked into rigid shapes similar to the process of making waffles or ice cream cones and is well-suited for molded shape pet treats. Various flavorings, colors, and the like may be added as desired, and products of different flavors, colors, and the like may be included in a commercial product line. Other edible starch-based molding materials can be used, such as potato starch or other edible starches, which then can be formed into molded shapes for pet treats via injection molding. Other materials or ingredients for making and shaping the containers may be used, such as gelatins, corn based, grain, sugar based, candy, flower based, chia seed based, dough based, and the like. Other manufacturing methods and materials for molding and shaping the containers may be used, such as pour molding, dye cut, press molding,  3 D printing, additive manufacturing, and the like. 
     In at least some embodiments, interlocking features (such as the various recesses, ledges, pegs, slots, and the like described herein) are provided so as to create sufficient coupling force to ensure that the various containers using such features are sealed against water leakage, at least to some degree, at least temporarily. More particularly, although various containers may, in at least some cases, be separated by hand by applying sufficient force to overcome the frictional forces holding them together (in the form of the various interlocking features being coupled together), such containers may be designed to withstand leakage of a liquid medicine or other ingestible material when placed inside, at least for a period of time from the moment the two halves are fully coupled together until the closed container is ingested by a pet  14 . Preferably, the coupling is strong enough to withstand internal hydrostatic pressure up to 1 PSI. More preferably, the coupling is strong enough to withstand internal hydrostatic pressure up to 5 PSI. 
     In various embodiments, containers of the present invention may be utilized with dogs and other canines, housecats and other felines, pigs, horses, and a wide variety of other animals, including at least some non-mammals.
