CROSS REFERENCE TO RELATED APPLICATION  
       [0001]     This application is a continuation-in-part of application Ser. No. 10/448,642, filed May 30, 2003, which is incorporated herein by reference. 
     
    
     FIELD  
       [0002]     This application concerns plastic caps and plastic bottles, such as bottles that are placed upside down into a receiving/dispensing tank of a dispenser, to which the caps may be attached, and more particularly, to tamper evident interlocking plastic caps and plastic bottles that hold water, particularly those that hold at least approximately 3 gallons of water.  
       BACKGROUND  
       [0003]     Water companies commonly supply users (in the home or office) with three- or five-gallon bottles to be placed upside down into a dispensing tank or water dispenser These water bottles are typically produced by manufacturers such that the cap presses on to the bottle over a crowned, y-shaped or double collar at the top of the bottle. The caps are typically made of flexible plastic to allow the cap to flex enough to allow it to be pressed over the top of the bottle in a machine bottling operation.  
         [0004]     One problem with such conventional designs is that the caps often do not provide effective sealing. For example, when the bottles are heated, as may occur during transportation or when exposed to the sun for prolonged periods of time, the flexible plastic cap can become quite flexible or expandable. In such conditions, the cap can be removed from, and reattached to, the bottle without breaking the seal of the plastic cap.  
         [0005]     As another example, when a heavy, three- or five-gallon bottle is lifted by grasping the cap, the cap can often accidentally slip off of the water bottle, particularly if the cap is exposed to heat.  
         [0006]     Accordingly, the cap can be intentionally removed in a similar fashion, the bottle contents can be tampered with, and the bottle cap can then be re-installed without providing much, if any, evidence of tampering. In other words, someone could remove a cap having a conventional design from a water bottle, insert a biological agent, such as anthrax, tularemia, botulism, or small pox, or a chemical agent, such as cyanide or mustard gas, and reattach the cap, without any resulting visible sign of tampering provided by the cap or any significant visible alteration of the structure of the cap.  
       SUMMARY  
       [0007]     The applicant believes that he was the first to recognize the deficiencies in conventional prior art three- and five-gallon water bottle caps noted above, particularly the risk of tampering associated with such caps.  
         [0008]     The applicant has invented a cap that can remain mounted to a water bottle container, particularly a conventionally-sized three- or five-gallon water bottle container, even after being exposed to heat, such as commonly occurs in the industry. The cap can be dismounted from the container by pulling a pull tab formed in the cap to severe the tab from the cap. Accordingly, the container of the system cannot be accessed without evidence of such access indicated in an at least partially severed pull tab.  
         [0009]     According to one embodiment, a container cap system includes a cap that has a body with a side wall coupled to a top portion. The side wall defines an interior and an exterior of the cap and has an inner surface proximate the interior and an outer surface proximate the exterior. The system includes a pull tab formed in the side wall that is configured to sever the side wall when pulled.  
         [0010]     At least one cap groove is formed in the inner surface of the side wall. The groove can have a generally v-shape with first and second major surfaces that are angled generally upward toward the top portion.  
         [0011]     The system can also include a container that has a container body and a container neck configured to dispense contents of the container. The container neck can include a neck wall that defines a neck interior and a neck exterior, a mouth that is formed in the container neck wall and at least one container groove formed in the exterior of the container neck wall. The at least one container groove can be generally v-shaped with first and second major surfaces angled generally downward at an angle away from the mouth. One of the first or second major surfaces of the at least one container groove can be configured to interlock with one of the first or second major surfaces of the at least one cap groove without rotation of the cap relative to the container. The pull tab can extend from a base of the cap to a location on the cap above the at least one cap groove and where pulling the pull tab severs the side wall to unseal the contents in the container interior. In some implementations, the pull tab is configured to tear from the side wall severing the side wall through the at last one cap groove enabling the cap to decouple from the container neck.  
         [0012]     In some implementations, the cap side wall and top portion have a generally cylindrical shape. The container neck can include a circumferential ring formed in the container neck wall that is configured to interface with a lower flare portion of the cap formed in the cap side wall opposite the top portion. The circumferential ring and the lower flare portion seal the interior of the container from external contaminants.  
         [0013]     In some implementations, the system includes a flat foam disc disposed in the interior of the cap proximate the top portion. The foam disc provides a seal between the cap top portion and the mouth.  
         [0014]     In certain implementations, the first and second major surfaces of the at least one cap groove are angled generally upward at an angle between approximately 5 degrees and 45 degrees toward the top portion. Similarly, the first and second major surfaces of the at least one container groove are angled generally downward at an angle between approximately 5 degrees and 45 degrees away from the mouth. The at least one cap groove can include at least six cap grooves and the at least one container groove can include at least six container grooves.  
         [0015]     According to one embodiment, a tamper indicating cap for sealing a water container includes a cylindrical hollow body having a closed top portion and an open bottom. The tamper indicating cap also includes a first annular tooth formed in the body proximate the closed top portion and extending from the body toward an interior of the body. The first annular tooth can have an upper surface and a lower surface that converge in a direction extending away from the body such that the lower surface is substantially parallel with the top portion and the top surface is downwardly angled in a direction extending away from the body.  
         [0016]     The tamper indicating cap can also include a second annular tooth formed in the body and positioned below the first annular tooth. The second annular tooth extends from the body toward an interior of the body and can have an upper surface and a lower surface that converge in a direction extending away from the body. The upper surface is downwardly angled away from the top portion in a direction extending away from the body and the lower surface is upwardly angled toward the top portion in a direction extending away from the body. A notch can be formed in the body proximate a location on the body where the lower surface of the second annular tooth adjoins the cylindrical hollow body.  
         [0017]     The tamper indicating cap can include a pull tab formed in the side wall that extends from the open bottom upward toward the top portion and circumferentially across the body between the first annular tooth and the second annular tooth.  
         [0018]     The first annular tooth and the second annular tooth of the tamper indicating cap are configured to contain a lip portion of the water container therebetween to seal the body to the container. The notch facilitates an upward directed biasing force against the lip portion of the water container. The container can be unsealed by severing the pull tab from the body.  
         [0019]     A method of using a container cap system includes aligning a container cap with a container where the container cap has a body that includes a side wall coupled to a top portion to define an interior and an exterior. The side wall has an inner surface proximate the interior and an outer surface proximate the exterior. The container cap can also have a pull tab formed in the side wall that is configured to sever the side wall. At least one cap groove having a generally v-shape and at least one cap tooth adjacent the at least one cap groove can be formed in the inner surface of the side wall.  
         [0020]     The method can further include pressing the container cap onto the water bottle container. The container can include a body and a container neck configured to dispense contents of the container, the container neck including a neck wall defining a neck interior and a neck exterior. The container can further include a mouth formed in the container neck wall distal from the container body where the mouth is configured to communicate with a container interior and a container exterior defined by the container body. At least one container groove having a generally v-shape and at least one container tooth adjacent the at least one container groove are formed in the exterior of the container neck wall. The at least one container groove can, if desired, interlock with the at least one cap tooth and the at least one cap groove can be configured to interlock with the at least one container tooth without rotation of the cap relative to the container. The cap is configured to demountably couple with the container neck and configured to seal the contents in the container interior.  
         [0021]     Alternatively, the water bottle container may have a conventional configuration, including of its neck. A cap having a cap tooth can nevertheless be installed on such a conventional water bottle using conventional bottling equipment. A single cap design may thus be utilized in conjunction not only with existing bottling machinery but also with both newly made bottles, which may have a mating configuration and thus be more reliably sealed via the cap, and with older or in any event differing water bottle neck structures not having a mating groove, for example. The single cap design may thus be backwardly compatible with the large pre-existing number of three- or five-gallon water bottles already in the market place for use and, often, for re-use without modification of the structure of the bottles.  
         [0022]     The method further includes interlocking the at least one cap groove with the at last one container tooth and the at least one container groove with the at least one cap tooth, and sealing the contents in the container exterior.  
         [0023]     The foregoing is a brief summary of aspects of the various embodiments disclosed in this specification. There are additional aspects that will become apparent as this specification proceeds. In addition, it is to be understood that embodiments of the invention need include all such aspects or address all issues in the prior art noted above.

       [0033]     In the following detailed description, various spacially orienting terms are used such as “upwardly” and “downwardly.” It is to be understood that such terms are used for convenience in association with the drawings and not themselves limiting or requiring of any absolute orientation in space.  
       DETAILED DESCRIPTION  
       [0034]     One embodiment of a tamper resistant or tamper evident cap container system includes a resilient cap having a pull tab that is mountable on a water bottle container, preferably a conventional three- or five-gallon water bottle container, such as water bottle container  180  shown in  FIG. 7 . As one example, a conventional five-gallon water bottle container can be made of plastic, can be approximately 17 inches in height and 11 inches in diameter, and can weigh approximately 40 pounds when filled with water. Although three- or five-gallon water bottle containers are preferred, it is recognized that water bottle containers of other shapes and sizes can also be used.  
         [0035]     The cap usually should remain mountably sealed to a container opening unless the pull tab has been at least partially severed from the cap. In any event, severance or partial severance of the pull tab from the cap visually indicates whether the cap has been tampered with. The cap includes at least one tooth and groove combination to interlock with the container to seal the cap to the container. In one exemplary implementation, the container includes at least one tooth and groove combination corresponding with the at least one tooth and groove combination of the cap to facilitate interlocking of the cap and the container.  
         [0036]     In general, the teeth of the disclosed embodiments have a generally tooth-shaped cross section, where the cap teeth extend circumferentially across an interior portion of the cap and the container teeth extend circumferentially across an exterior portion of the container. Similarly, the grooves of the disclosed embodiments extend circumferentially across the interior of the cap in the case of cap grooves and the exterior of the container in the case of container grooves. Although preferably the teeth and grooves extend seamlessly across the cap or container, it is recognized that the teeth and grooves can be partitioned or non-continuous as they extend circumferentially across the cap or container.  
         [0037]     Referring to  FIGS. 1 through 4 , according to one embodiment, a container cap system  10  includes an improved tamper evident cap  12  to be used with a container, such as container  14 , which can be a three- or five-gallon water bottle. The cap  12  can be pressed onto the container  14  using standard bottling machinery. As best shown in  FIG. 2 , the cap  12  includes a body having a side wall  16  and a top portion  18 . The side wall  16  and top portion  18  define an interior  20  and an exterior  22  of the cap  12 . The side wall  16  has an inner surface  24  adjacent the interior  20  and an outer surface  26  the exterior  22 .  
         [0038]     The cap  16  includes a plurality of cap grooves, with exemplary grooves indicated at  32 , each having a generally v-shape and a corresponding plurality of teeth  33 , with exemplary teeth indicated at  33 , each having a generally v-shape and positioned adjacent to at least one groove  32 . A lower surface of the cap grooves  32  can extend in an inward direction, i.e., a direction moving away from a sidewall of the cap toward the interior of the cap, at a predetermined angle  34  relative to horizontal, as shown in  FIG. 2 , toward the top portion  18  of the cap  12 . As used herein, horizontal refers to a plane generally parallel to an upper surface of the container where the upper surface is generally parallel to the ground when the container is uprightly resting on the ground. In some specific implementations, the angle  34  can be approximately five degrees. In other implementations, the angle  34  can be less than or more than five degrees. In an exemplary embodiment, six cap grooves  30  are formed in the side wall  16 . Of course, the cap  16  can have more or less than six cap grooves.  
         [0039]     One type of three- or five-gallon water gallon container  14  can include a container body  42  and a container neck  44  having a neck wall  46  defining neck interior  48  and a neck exterior  50 . A plurality of container grooves, exemplary grooves being indicated at  58 , each having a generally v-shape in cross-section and a plurality of corresponding teeth, exemplary teeth being indicated at  59 , each having a generally v-shape in cross-section and positioned adjacent to at least one groove  58 , are formed in the neck wall  46  adjacent the neck exterior  50 . An upper surface of the container grooves  58  can be formed to extend in an outward direction, i.e., a direction moving away from a sidewall of the container toward the exterior of the container, at a predetermined angle  60  relative to horizontal, as shown in  FIG. 3 , away from the mouth  52  when extending in an outward direction. Preferably, the angle  60  is approximately equal to the angle  34 . In some specific implementations, the angle  60  can be approximately five degrees. In other implementations, the angle  60  can be less than or more than five degrees. In the illustrated embodiment shown in  FIGS. 1 through 4 , there are six container grooves  58 . Of course, the container  14  can have more or less than six container grooves.  
         [0040]     The water bottle container grooves and teeth interlock with the cap teeth and grooves as the cap is inserted onto the container without rotation of the cap relative to the container, e.g., by press-fit of the cap  16  onto the container  14 . More specifically, as shown in  FIG. 4 , teeth  59  in the container  14  are nestably inserted into corresponding grooves  32  in the cap  12  and teeth  33  in the cap are nestably inserted into corresponding grooves  58  in the container. When interlocked, the container grooves  58  and cap grooves  32  form a seal, which can help prevent leakage of the contents from the container  14  as well as prevent undesired tampering with the contents of the container  14 .  
         [0041]     The interlocking configuration of the teeth and grooves also can provide resistance to heat expansion and, in any event, tampering (even in the event of heat expansion) of the cap  16  or portions of it. The container grooves  58  being angled downwardly with respect to horizontal and the cap grooves  32  being angled upwardly with respect to horizontal, interact with the cap teeth  33  and the container teeth  59 , respectively, to resist movement of the cap  12  upwardly, i.e., vertically, with respect to the container. The respective cap and container teeth are preferably made from a plastic, such as polyethylene, that is sufficiently rigid such that the teeth do not disengage the respective container and cap grooves as the cap is pulled upwardly away from the container even if the cap and container are in a heated environment. In this way, the cap  12  cannot be removed from the container  14  by pulling on the cap relative to the container  14 .  
         [0042]     The angles of the upper and lower surfaces of the teeth and grooves of the embodiments of the cap container system described herein can be predetermined based on the desired level of resistance to upward directed pulling on the cap relative to the container. In other words, for example, in certain high-heat or high-security applications or environments, it may be desirable to have greater resistance to unevidenced tampering of the system by pulling the cap off of the container. In these applications, the predetermined angles of the teeth and grooves can be increased to increase the resistance. In other applications where little resistance is sufficient, the predetermined angles of the teeth and grooves can be less than for high-resistance applications.  
         [0043]     The cap is removable and tampering can be shown by use of a pull tab. The cap  12  has a pull tab  28  formed at least partially adjacent the side wall  16  to facilitate selective removal of a portion of the cap  12 . The pull tab  28  includes scored edges  30  and a handle portion  29  configured to allow for easy tearing of the pull tab away from the side wall  16  by grasping and pulling the handle portion outwardly and upwardly away from a lower edge of the sidewall such that the pull tab tears along the scored edges.  
         [0044]     Once installed on the container  14 , the water bottle cap  12  cannot be removed without pulling the tab  28  and severing the side wall  16 . Accordingly, any tearing of the pull tab  28  away from the side wall  16  of the cap  12  will reveal tampering of the container cap system  10 , i.e., removal or attempted removal of the cap from the container.  
         [0045]     In some embodiments, the top portion  18  of the cap  12  includes rounded edges  36  at the interface with the side wall  16 . The cap side wall  16  includes a lower flare portion  38  opposite the top portion  18 . The lower flare portion  38  can promote proper alignment of the cap  12  and the container  14  as well as provide for a sealing surface. In some embodiments, a foam disc  40  is disposed in the interior  20  of the cap  16  near the top  18 . The foam disc  40  is configured to seal between the cap  16  and the container  14 .  
         [0046]     The container  14  includes a circumferential ring  62  formed in the neck  44  proximate the container body  42 . The circumferential ring  62  is configured to interface with the lower flare portion  38  of the cap  12  in order to seal the interior  54  of the container from external contamination and leakage to the exterior  56 . The container includes a mouth  52  formed in the container neck  44  distal from the container body  42  and configured to communicate with a container interior  54  and a container exterior  56  formed by the container body  42 . The top of the mouth  52  of the bottle  14  also has a slight rounded top  64 , to facilitate lining up the cap in the bottling process.  
         [0047]     As a result, the cap  12  can, if desired, be used in conjunction with standard bottling equipment, preventing the need to invest in new machinery and allowing the bottler to use, and if desired, re-use conventional prior art three- or five-gallon water bottles. The bottler can therefore commence using the cap  12  with water containers having mating, tamper resistant structure as described herein but without having to abandon or alter the bottler&#39;s existing machinery and system of use of the machinery with conventional prior art caps.  
         [0048]     With regard to the present bottle container of  FIG. 3 , however, the mouth  52  of the container  14  includes a rounded outer edge  64  configured to facilitate alignment of the cap  12  with the container neck  44 . The container neck  44  is configured to dispense contents within the container  14 . In an exemplary embodiment, the container neck  44  is a right circular cylinder. Generally, the cap  12  is a straight cylinder having diameter just wide enough to allow a relatively tight fit on the bottle  14 .  
         [0049]     The container neck  44  can also have a generally straight cylindrical shape. As shown in  FIG. 3 , the neck  44  of the container  14  is vertically straight below the rounded top  64  of its mouth  52 . The grooves  58  and teeth  59  are also formed in the neck wall  46  of the neck above a circumferential ring  62  formed in the neck. The circumferential ring  62  interfaces with the lower flare of the cap  38  to provide a barrier against contaminants intermixing with the contents of the container.  
         [0050]     Referring now to  FIG. 5 , an alternative embodiment of a cap container system  100  is shown with a cap  102  mounted to a container  104 . The cap  102  includes a first lower cap tooth  106   a , a second lower cap tooth  106   b , a lower container lip gripping tooth  108 , and an upper container lip gripping tooth  110  formed in a side wall  138  of the cap.  
         [0051]     The first lower cap tooth  106   a  is positioned on the cap between a circumferential ring receiving groove  112  and a second container tooth receiving groove  114 . The second lower cap tooth  106   b  is positioned on the cap between the second container tooth receiving groove  114  and a first container tooth receiving groove  116 . Each lower cap tooth  106   a ,  106   b  can have an upper surface and a lower surface that converge as the tooth extends away from the side wall  138 . Both the upper surface and the lower surfaces of the teeth  106   a ,  106   b  are upwardly angled toward a top portion  120  of the cap  102  in the inward direction. In one specific implementation, the upper surfaces of the teeth  106   a ,  106   b  are upwardly angled approximately five degrees from horizontal in  FIG. 5 . In other implementations, the angle of the upper surfaces can be more or less than five degrees depending on the desired level of resistance to upward directed pulling on the cap relative to the container.  
         [0052]     The lower container lip gripping tooth  108  is intermediate the first container tooth receiving groove  116  and a container lip receiving groove  118 . The tooth  108  includes converging upper and lower surfaces extending inwardly, with the upper surface angled downwardly away from top portion  120  and the lower surface angled upwardly toward the top portion. In one specific implementation, the upper surface of the tooth  108  is downwardly angled at approximately 5 degrees. In other implementations, the angle of the upper surface of the tooth  108  can be more or less than 5 degrees.  
         [0053]     The upper container lip gripping tooth  110  is intermediate the container lip receiving groove  118  and the top portion  120  of the cap  102 . The tooth  110  also has converging upper and lower surfaces. In one specific implementation, the upper surface extends generally transverse to the top portion  120 , and the lower surface extending inwardly in a direction approximately parallel with the top portion of the cap. In other implementations, the upper surface can be angled downwardly and the lower surface can be angled upwardly relative to horizontal.  
         [0054]     The container  104  includes an upper thickened container lip  122 , a radially outwardly projecting first container tooth  124  below the upper thickened container lip  122 , a radially outwardly projecting second container tooth  126  below the first container tooth  124 , and a radially outwardly extending circumferential ring  128  below the second container tooth  126 .  
         [0055]     The container lip  122  is positioned on an uppermost portion of a neck  130  of the container  104  and adjacent a lower container lip gripping tooth receiving groove  132 . The lip  122  can have a generally rounded circumferential uppermost edge to facilitate mounting of the cap  102  to the container  104  as shown in  FIG. 5 .  
         [0056]     The first container tooth  124  is positioned on the neck  130  between the groove  132  and a second lower cap tooth receiving groove  134 . The tooth  124  has converging upper and lower surfaces extending in the outward direction with the upper and lower surfaces angled downwardly away from the lip  122 . In one specific implementation, the upper surface is angled downwardly 60 degrees and the lower surface is angled downwardly approximately 5 degrees with respect to horizontal. In other implementations, the upper surface can be angled at more or less than 60 degrees and the lower surface can be angled at more or less than 5 degrees.  
         [0057]     The second container tooth  126  has converging upper and lower surfaces extending in the outward direction with the upper and lower surfaces angled downwardly away from the lip  122 . In one specific implementation, the upper surface is angled downwardly at approximately 45 degrees and the lower surface is angled downwardly approximately five degrees with respect to horizontal. In other implementations, the upper surface of the second container tooth  126  can be angled at more or less than 45 degrees and the lower surface can be angled at more or less than 5 degrees.  
         [0058]     The cap  102  can be mounted to the container  104  in a manner similar to that described above in relation to the cap container system  10  shown in  FIGS. 1 through 4 . As shown in  FIG. 5 , when the cap  102  is mounted to the container  104 , the first lower cap tooth  106   a , the second lower cap tooth  106   b , and the lower container lip gripping tooth  108  of the cap interlocks with the first lower cap tooth receiving groove  136 , second lower cap tooth receiving groove  134  and the lower container lip gripping tooth receiving groove  132  of the container, respectively. Further, the container lip  122 , the first container tooth  124 , the second container tooth  126  and the circumferential ring  128  interlock with the container lip receiving groove  118 , the first container tooth receiving groove  116 , the second container tooth receiving groove  114  and the circumferential ring receiving groove  112  of the container  104 , respectively. Additionally, the upper container lip gripping tooth  110  interacts with the container lip  122  to provide additional retention of the cap  102  on the container  104 .  
         [0059]     The cap  102  includes a pull tab  172  that has a severable thin-walled perforation extending from a base of the cap upward toward the top portion of the cap and circumferentially across the cap at a notch  140  formed between the lower container lip gripping tooth  108  and the second lower cap tooth  106   b.    
         [0060]     Once mounted to the container  104 , the cap  102  cannot be removed without tearing the pull tab  172  formed in the cap away from the cap, which evidences tampering of the cap and container. This is because the first lower cap tooth  106   a  and the second lower cap tooth  106   b  are upwardly angled toward the top portion  120  of the cap such that when the cap  102  is mounted to the container  104 , with the pull tab  172  intact, the interaction of the teeth  106   a ,  106   b  with the grooves  136 ,  134 , respectively, prevents movement of the cap outwardly away from the container, i.e., dismounting of the cap from the container.  
         [0061]     The lower container lip gripping tooth  108  also provides resistance to dismounting of the cap  102  from the container  104  by interacting with the lower container lip gripping tooth receiving groove  132  of the container.  
         [0062]     Once the pull tab  172  is severed from the cap  102 , the cap can be removed from the container  104 . Further, once removed, the cap  102  can be removably re-mounted to the container  104  by pressing the cap onto the bottle such that the lip portion  122  of the container is effectively clamped by the container lip gripping tooth  108  and the upper container lip gripping tooth  110 .  
         [0063]     In addition to container  104 , which is specifically configured to mate with cap  102 , as shown in  FIGS. 6A, 6B  and  6 C, the cap  102  can also accommodate sealing of conventional container types, in other words, the cap can be backwards compatible to fit existing containers such that old bottles and machinery may continue to be used. For example, as shown in  FIG. 6A , the cap  102  can be removably mounted to a conventional container  160  by pressing the cap onto the container such that a lip portion  170  of the container is positioned in the container lip receiving groove  118  between the lower container lip gripping tooth  108  and the upper container lip gripping tooth  110  to effectively clamp or contain the lip  170  in place.  
         [0064]     Alternatively,  FIGS. 6B and 6C  show the cap  102  being mounted to conventional containers  162  and  164 , respectively. As with the cap  102  and container  160  combination of  FIG. 6A , a lip portion  166 ,  168  of the containers  162 ,  164 , respectively is positioned in the container lip receiving groove  118  of the cap when the cap is mounted to the containers to removably secure the cap to the containers.  
         [0065]     As can be appreciated from the foregoing, when mounted to the modified bottle  104 , the cap  102  is prevented from being removed from the modified bottle without evidencing tampering, i.e., without tearing the pull tab  172  away from the cap, and when mounted to an existing or conventional bottle, the cap can seal and re-seal the existing bottle without requiring modification of the existing bottles or bottle-making machinery.  
         [0066]     The cap container system of the present disclosure can provide the following several advantages: (a) to provide a cap for mounting to a modified three- or five-gallon plastic water bottle, such when the cap is attached to the mouth of a bottle, it locks onto the top of the bottle such that the seal cannot be broken without severing the cap by pulling the plastic tab of the bottle to remove the cap; (b) to provide a cap and bottle of the type disclosed herein that can be used with existing bottling machinery; and (c) to provide a backwards compatible cap container system that can be used on existing conventional water bottles of various sizes and configurations.  
         [0067]     While embodiment and applications of the cap container system have been shown and described, it would be apparent to those skilled in the art that many more modifications than mentioned above are possible without departing from the inventive concepts herein. The disclosure, therefore, is not to be restricted except in the spirit of the appended claims.
