       BACKGROUND OF THE INVENTION  
         [0002]    The present invention is directed to methods and apparatus for dispensing liquids, and more particularly is directed to dispensing liquid from a tamper-proof container. More specifically the present invention relates to dispensing cleaning products from a tamper-proof container suitable for use in jail, correctional facility, school, public facility, or any other location subject to abuse or vandalism.  
           [0003]    Liquid and soap dispensers have been used for many years. These dispensers are used in a number of applications, including: soap dispensers in restrooms, beverage dispensers, liquid dispensers at gas stations, etc. For example U.S. Pat. No. 4,911,212 discloses a device used to dispense water or other liquids into a reusable container. U.S. Pat. No. 5,088,621 discloses a dispenser to be used at a gas station. The &#39;621 patent discloses an apparatus used to dispense a predetermined amount of liquid from a reservoir mounted on the dispenser. These devices although suitable in many applications do not provide a tamper-proof dispenser.  
           [0004]    Therefore there is a need for a tamper-proof dispenser that can be used in correctional facilities, prisons, jails, public restrooms, schools and other facilities or institutions where the dispenser is susceptible to abuse or vandalism.  
         SUMMARY OF THE INVENTION  
         [0005]    The present invention advantageously addresses the needs above as well as other needs by providing a tamper-proof apparatus for dispensing liquid including a chamber, a supply reservoir, a plunger, a output tube, an outlet, an outlet shield, a lockable door, a lockable flap, a hole in the top of the chamber and a horizontal plate.  
           [0006]    The present invention can be characterized in one embodiment as a tamper-proof apparatus for dispensing a liquid comprising a chamber; a lockable door making up at least a part of one side of the chamber; a supply reservoir within the chamber; a plunger coupled to the supply reservoir; a hole in the chamber; and a actuator coupled within the chamber adjacent to the hole; wherein the actuator is within the chamber, such that if pressure is applied to the actuator the plunger is actuated.  
           [0007]    In another embodiment the present invention can be characterized as a tamper-proof apparatus for dispensing a liquid comprising a chamber for storing the liquid; an outlet in the chamber for dispensing the liquid; and an outlet shield protecting the outlet from damage.  
           [0008]    In yet another embodiment the present invention can be characterized as a method of dispensing liquid from a dispensing unit comprising storing a liquid in a supply reservoir within a lockable chamber; applying pressure to an actuator within the lockable chamber through a hole in the lockable chamber; and dispensing the liquid through an outlet in the lockable chamber, the outlet being covered by an outlet shield to protect the outlet from damage.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0025]    The following description of the presently contemplated best mode of practicing the invention is not to be taken in a limiting sense, but is made merely for the purpose of describing the general principles of the invention. The scope of the invention should be determined with reference to the claims.  
         [0026]    Referring first to FIG. 1 shown is a perspective view of a dispensing unit  10  for use with a liquid, such as soap and other cleaning or chemical materials. Shown is the dispensing unit  10 , a supply reservoir  12 , an output hose  14 , a lockable door  16 , a door frame  18 , an overhang  20 , a first door hasp  22 , a second door hasp  24 , a door hinge  26 , a top  28 , a base  30 , a lockable flap  32 , a flap hole  34 , a top hasp  36 , a side hasp  38 , a flap hinge  40 , a door lock  52 , and a flap lock  42 .  
         [0027]    The dispensing unit  10  has the lockable door  16  on the front. Above the lockable door  16  is the overhang  20 , further described with reference to FIG. 2. The lockable door  16  is attached to the dispensing unit  10  by the door hinge  26 , which is recessed such that a hinge pin  78 , shown in FIG. 7, is covered by the top  28  of the dispensing unit  10  or the base  30  of the dispensing unit  10 . Advantageously, the lockable door  16  and the overhang  20  could also be positioned on the side of the dispensing unit  10 .  
         [0028]    Shown is the lockable door  16  in an open position, such that there is access to the supply reservoir  12 . The flap  32  is shown in the closed position, such that the dispensing unit  10  cannot be used. The flap  32  is locked in the closed position to the top hasp  36  with the flap lock  42 .  
         [0029]    The operation and function of the supply reservoir  12  and output hose  14  will be further described with reference to FIGS. 2 and 3. The operation and function of the flap  32  will be further described with reference to FIGS. 4, 5, and  8 .  
         [0030]    Referring to FIG. 2 shown is a side partial cross-sectional view of the dispensing unit  10  of FIG. 1. Shown is the dispensing unit  10 , the overhang  20 , the output hose  14 , an outlet  44 , a plunger  46 , a supply reservoir cap  48 , the supply reservoir  12 , a horizontal plate  50 , the door lock  52 , the first door hasp  22 , the second door hasp  24 , the flap hinge  40 , the flap  32 , the top hasp  36 , the side hasp  38 , the flap hole  34 , and the flap lock  42 .  
         [0031]    The supply reservoir  12  is contained within the dispensing unit  10  to protect it from vandalism or being damaged. The supply reservoir cap  48  is screwed on the top of the supply reservoir  12 . The plunger  46  goes through a hole in the supply reservoir cap  48  and down into the supply reservoir  12 . The supply reservoir  12 , the supply reservoir cap  48 , and the plunger  46  are commonly know in the art. The output hose  14  is coupled to the plunger  46  at one end and to the outlet  44  at the other end. The outlet  44  is a hole in the overhang  20 . Advantageously, the outlet  44  can be a metal feed-through to which the output hose  14  is coupled. Shown is the flap  32  locked in the open position to the side hasp  38 . This allows the dispensing unit  10  to be operated.  
         [0032]    The overhang  20  is above the lockable door  16  on the front of the dispensing unit  10 . The outlet  44 , preferably a metal feed-through, is coupled to the output hose  14 . The outlet  44  comes through the overhang  20  at the front of the dispensing unit  10  above the lockable door  16 . While the overhang  20  extends the width of the dispensing unit  10 , the overhang  20  could also be less than or greater than the width of the dispensing unit  10 .  
         [0033]    Referring to FIG. 3 shown is a partial front cross-sectional view of the dispensing unit  10  of FIG. 1. Shown is the dispensing unit  10 , the overhang  20 , the output hose  14 , the flap hinge  40 , the flap  32 , the side hasp  38 , the top hasp  36 , the lockable door  16 , the first door hasp  22 , the door hinge  26 , the supply reservoir  12 , the supply reservoir cap  48 , the plunger  46 , the horizontal plate  50 , a first security screw  54 , a second security screw  56 , a first spacer  58 , a second spacer  60 , a first nut  62 , a second nut  64 , the outlet  44 , and the door lock  52 .  
         [0034]    A security screw, e.g., a prison screw, is a screw that requires a special tool to remove it from the nut. Because the special tool is required there is much less of a chance the screw can be removed, preventing the dispensing unit  10  from being dismantled and preventing the screw from being furnished into a weapon. A prison screw is a one type of security screw. Prison screws are a screws that comprise a hexagonal indentation in their upper surface or head, and further include a pin located in a center of the hexagonal indentation, such that they cannot be removed with an ordinary hexagonal wrench, but rather require a special tool, such as a hexagonal wrench with a center bore at one end, so as to accommodate the pin located in the center of the hexagonal indentation, and thereby allow insertion of the special tool to be inserted into the hexagonal indentation, so that it can engage such indentation and thereby allow the prison screw to be rotated by the special tool, and thereby inserted or removed, i.e., screwed in or unscrewed.  
         [0035]    The top  28  of the dispensing unit  10  has the first security screw  54 , the second security screw  56 , a third security screw  68 , and a fourth security screw  70  through it. The first security screw  54  goes through the horizontal plate  50  and through the first spacer  58 . The first security screw  54  is then coupled to the first nut  62 . The second security screw  56 , the third security screw  68 , and the fourth security screw  70  are similarly configured.  
         [0036]    The horizontal plate  50  rests on top of the plunger  46 . Shown is the horizontal plate  50  depressed, such that it is on top of the first spacer  58 , the second spacer  60 , a third spacer, and a fourth spacer  108 . This prevents the horizontal plate  50  from being further depressed. The top hole  66 , shown in FIG. 4, in the top  28  of the dispensing unit  10  is above the horizontal plate  50 , preferably at the center of the horizontal plate  50 . The top hasp  36  is welded to the top  28  of the dispensing unit  10 . The flap  32  has the flap hole  34  which the top hasp  36  can go through. The flap  32  is coupled to the flap hinge  40 . The side of the dispensing unit  10  also has the side hasp  38  welded to the dispensing unit  10 . The side hasp  38  can also go through the flap hole  34  in the flap  32 . The flap lock  42  can lock on either the side hasp  38  or the top hasp  36 .  
         [0037]    When the flap  32  is locked in the open position, thus allowing access to the top hole  66 , the dispensing unit  10  can be used to dispense a liquid, such as soap. A user can push down on the horizontal plate  50  through the top hole  66 . The horizontal plate  50  rests on top of the plunger  46 , thus when the horizontal plate  50  is pushed down the plunger  46  is also pushed down. The spacers below the horizontal plate  50  will limit the distance the plunger  46  can be depressed. When the horizontal plate  50  no longer has pressure being put upon it the plunger  46  and horizontal plate  50  will move upward. The plunger includes, for example, a spring that causes the plunger to return to a upward position, thus, causing the plate to return to the upward position. The plunger includes, for example, a spring that causes the plunger to return to an upward position, thus, causing the plate to return to the upward position. Liquid travels through the output hose  14  and through the outlet  44  when the plunger  46  is being depressed. The plunger  46  and supply reservoir  12  are commonly known in the art. Advantageously, the height of the spacers determines how much liquid per depression will be dispensed from the dispensing unit  10 . The shorter the height of the spacers the more the plunger  46  can be depressed causing more liquid to be dispensed through the outlet  44  each time the plate is depressed. Advantageously, if only a small amount of liquid is needed, tall spacers can be inserted to allow only a small movement of the plunger  46 . Placing tall spacers beneath the horizontal plate  50 , helps reduce the amount of waste, as only a small amount of liquid will be dispensed per depression. Preferably, the liquid being dispensed is hand soap, body soap, or dishwashing soap.  
         [0038]    Advantageously, as shown in FIGS. 2 and 3, the outlet  44  is above the plunger  46  to minimize the amount of liquid that can drip from the outlet  44 . When the plunger  46  is depressed liquid will be forced through the output hose  14  and out the outlet  44 . However, when the plunger  46  is then released, excess liquid will naturally be drawn by gravity back to the plunger  46 , instead of to the outlet  44 . This keeps excess liquid from dripping onto, for example, the floor. Additionally, a short output hose  14  is used such that as little excess liquid remains in the output hose  14 . Even if the outlet  44  is positioned below the plunger  46 , the short output hose would allow only a minimal amount of liquid to drip out the outlet  44 .  
         [0039]    The horizontal plate  50  protects the supply reservoir  12 , the plunger  46  and the output hose  14  from vandalism. The horizontal plate  50  allows the plunger  46  to be depressed without giving access to the supply reservoir  12 . For example, an inmate in a correctional facility operating the dispensing unit  10  could not reach inside and get their fingers below the horizontal plate  50 . If the horizontal plate  50  was not present the inmate would have direct access to the plunger  46  and the output hose  14  through the top hole  66 . Furthermore, the horizontal plate  50 , in conjunction with the spacers  58 ,  60 , serves to limit the amount of liquid dispensed per depression, as described above.  
         [0040]    The output hose  14  is coupled to the outlet  44  such that access to the output hose  14  is limited to when the lockable door  16  is unlocked and open. When the lockable door  16  is locked the output hose  14  is entirely enclosed in the dispensing unit  10 . This prevents an inmate or other vandal from pulling on the output hose  14  and damaging the output hose  14 , the supply reservoir  12 , or the plunger  46 . Advantageously, the outlet  44  can be a welded in metal feed-through to which the output hose  14  is coupled on the inside of the dispensing unit  10 . The welded in metal feed-through is welded to the dispensing unit  10 , beneath the overhang  20 , this prevents the output hose  14  from being pulled upon from the outside of the dispensing unit  10 .  
         [0041]    The flap  32  on top  28  of the dispensing unit  10  can be locked in either the open or closed position. When the flap  32  is locked in the open position, it is locked to the side hasp  38  and the horizontal plate  50  can be depressed. When the flap  32  is locked in the closed position, it is locked to the top hasp  36  and covers the top hole  66  in the top  28  of the dispensing unit  10 . Advantageously, this prevents the dispensing unit  10  from being used at improper times. This also limits the amount of liquid being dispensed and prevents needless waist of liquid, such as soap. When the flap  32  is locked in the open position, this prevents the flap  32  from being damaged or vandalized during normal operation. For example, in a correctional facility, an inmate using the dispensing unit  10  could not move the flap  32  around or attempt to remove the flap  32  as easily because it is locked to the side of the dispensing unit  10 . The flap  32  is further shown in FIG. 8.  
         [0042]    Advantageously, the lockable door  16  is recessed in the front of the dispensing unit  10  such that a hinge pin  78 , shown in FIG. 7, cannot be slid out of the door hinge  26 . FIG. 7 further shows this feature. The lockable door  16  can be opened to change or fill the supply reservoir  12  or any other damaged parts, although it is normally locked to prevent access to the inside of the dispensing unit  10 .  
         [0043]    The first door hasp  22  is welded to the lockable door  16 . The second door hasp  24  is welded to the side of the dispensing unit  10 , such that the hole in the first door hasp and the hole in the second door hasp line up when the lockable door  16  is closed. The door lock  52  can be put through the holes and closed to lock the door. The first door hasp  22  and the second door hasp  24  are advantageously welded to the dispensing unit  10 . The first door hasp  22  and the second door hasp  24  could be screwed to the dispensing unit  10 , however, this may allow for the possible removal of the screws if precautions, such as using security screws, were not taken.  
         [0044]    Referring to FIG. 4 shown is a partial top cross-sectional view of the dispensing unit  10  of FIG. 1. Shown is the top  28  of the dispensing unit  10 , the top hole  66 , the first security screw  54 , the second security screw  56 , the third security screw  68 , the fourth security screw  70 , the horizontal plate  50 , the flap  32 , the flap hinge  40 , the flap hole  34 , the first hinge screw  72 , the second hinge screw  74 , the third hinge screw  76 , and the top hasp  36 .  
         [0045]    Shown is the top  28  of the dispensing unit  10  when the flap  32  is in the open position. This allows access to the top hole  66  so the dispensing unit  10  can be used. The first hinge screw  72 , the second hinge screw  74 , and the third hinge screw  76 , secure the flap  32  to the top  28  of the dispensing unit  10 . Advantageously, the first hinge screw  72 , the second hinge screw  74 , and the third hinge screw  76  are safety or prison screws. This is further described and shown in FIG. 8. Shown is the top hole  66  over the center of the horizontal plate  50 .  
         [0046]    Referring to FIG. 5 shown is a partial top cross-sectional view of the dispensing unit  10  of FIG. 1 with the flap  32  locked in the closed position. Shown is the top  28  of the dispensing unit  10 , the flap  32 , the flap hinge  40 , the flap hole  34 , the flap lock  42 , the side hasp  38 , and the top hasp  36 .  
         [0047]    Shown is the top  28  of the dispensing unit  10  when the flap  32  is locked, such that the dispensing unit  10  cannot be used. The flap  32  covers the top hole  66 , such that the horizontal plate  50  is not exposed. Thus, the horizontal plate  50  cannot be depressed and liquid will not be dispensed from the dispensing unit  10 . Advantageously the flap  32  is welded to or integral with the flap hinge  40  such that it is not necessary to have nuts exposed on the outside of the dispensing unit  10 . This is further described and shown in FIG. 8.  
         [0048]    Referring next to FIG. 6, shown is an end of the door hinge  26 . Shown is the door hinge  26 , the hinge pin  78 , and crimps  80 .  
         [0049]    The crimps  80  in the door hinge  26  secure the hinge pin  78  to the door hinge  26 . The door hinge  26  is crimped only on alternative sections so as to allow the lockable door  16  to open while not allowing the hinge pin  78  to slide out of the door hinge  26 . Advantageously, this does not allow an inmate in a jail or prison to remove the hinge pin  78  and finish it into a weapon.  
         [0050]    Referring to FIG. 7, a top view is shown of the door hinge  26 . Shown is the door hinge  26 , the lockable door  16 , the door frame  18 , the hinge pin  78 , a first door hinge screw  81 , a second door hinge screw  82 , a first safety bar  84 , a second safety bar  86 , a first lock nut  88 , and a second lock nut  90 .  
         [0051]    The door hinge  26  is recessed, so that the hinge pin  78  will not clear a frame of the lockable door  16 , and thus cannot be removed from the door hinge  26 , even if the crimps  80  in the door hinge  26  are loosened. The top  28 , shown in FIG. 4, of the dispensing unit  10  will always be on top  28  of the hinge pin  78 , whether the lockable door  16  is open or closed, thus preventing the hinge pin  78  from sliding out of the door hinge  26 . The hinge pin  78  may also be optionally welded to the door hinge  26  at its ends, to further make difficult its removal.  
         [0052]    The dashed line in FIG. 7, extending from the lockable door  16  to the door frame  18 , represents the top  28  of the dispensing unit  10 . The hinge pin  78  is underneath the top  28  of the dispensing unit  10 , with very little space between the lockable door  16  and the top  28  of the dispensing unit  10  (better shown in FIG. 3). In order for the hinge pin  78  to slide out of the door hinge  26  the hinge pin  78  needs adequate space above the hinge pin  78 . For example, the space between the hinge pin and the top of the dispensing unit  10  is small enough such that the hinge pin  78  could not be partially slid out of the door hinge  26  and then bent allowing for the hinge pin  78  to be further slid out of the door hinge  26 , which eventually could lead to the hinge pin  78  being completely removed. Thus, because of the small space between the top  28  of the dispensing unit  10  and the hinge pin  78 , if the hinge pin were attempted to be removed it would simply hit the top  28  of the dispensing unit  10  before it could be bent and its removal would be prevented. Even when the lockable door  16  is open, the hinge pin  78  has not moved out from underneath the top  28  of the dispensing unit, only the door has rotated, therefore, whether the lockable door  16  is open or closed, the hinge pin  78  will not be removable as it will still be underneath the top  28  of the dispensing unit  10 . The bottom of the dispensing unit  10  functions in the same manner for a hinge pin  78  located at the bottom of the door hinge  26 .  
         [0053]    The door hinge  26  is secured to the lockable door  16  using the first door hinge screw  81 , which is preferably a prison screw or other difficult to remove fastener. The first door hinge screw  81  passes through the door hinge  26 , through the lockable door  16 , and through the first safety bar  84  to the first lock nut  88 , i.e., a hex nut including a nylon insert. Advantageously, the first safety bar  84  is aligned parallel to the door hinge  26  with the door frame  18  interposed between the safety bar  84  and the door hinge  26 , and is threaded, such that even in the event the first lock nut  88  is removed, the first door hinge screw  81  is not readily removable from the door hinge  26 . The first safety bar  84  and second safety bar  86  are strips of metal with threaded holes that are positioned along the safety bars so that they can be aligned with and juxtaposed against screw holes in the lockable door  16  and the door frame  18 , respectively, and engaged by the first door hinge screw  81  and the second door hinge screw  82 . The first door hinge screw  81  and the second door hinge screw  82  advantageously can be safety screws, e.g., prison screws. Both sides of the door hinge  26  are secured, respectively, to the door frame or the lockable door  16 .  
         [0054]    The second door hinge screw  82 , which is also preferably a prison screw or other difficult to remove fastener passes through the door hinge  26 , through the door frame and through the second safety bar  86 . The second door hinge screw  82  is then inserted into the second lock nut  90  i.e., a hex nut including a nylon insert. The second safety bar  86  is also threaded, such that even in the event the second lock nut  90  is removed, the second door hinge screw  82  is not readily removable. When the first door hinge screw  81  and second door hinge screw  82  are prison screws a special tool is needed to remove them, which helps prevent an inmate from easily removing the screws. Advantageously, the screws are only accessible when the lockable door  16  is unlocked and open, further preventing their removal. This is important in a jail or correctional facility where a screw can be finished into a weapon.  
         [0055]    Referring to FIG. 8 shown is an enlarged view of the flap hinge  40  shown in FIG. 3. Shown is the top  28 , the flap hinge  40 , the flap  32 , a safety bar  92 , a hinge nut  94 , a flap hinge pin  96 , and the first hinge screw  72 .  
         [0056]    Advantageously, the flap hinge  40  is crimped on alternate sections just as the door hinge  26  is crimped (see FIG. 6) such that the flap hinge pin  96  is not readily removable from the flap hinge  40 . The flap hinge  40  is crimped only on alternative sections so the flap hinge  40  is still able to open or close. The flap hinge  40  can also be welded to the flap hinge pin  96  on either or both ends to further make difficult the removal of the flap hinge pin  96 . The flap hinge pin  96  can be finished into a weapon if it is removed, thus it is desirable to make it as difficult as possible to remove.  
         [0057]    The flap  32  is welded to one side of the flap hinge  40 . Advantageously, because the flap  32  is welded to the flap hinge  40  (or integral therewith, i.e., on extension of the flap hinge  40 ) instead of attached through the use of screws, there is a reduced risk of an inmate being able to remove a nut and screw from the dispensing unit  10  and using the screw as a weapon. Alternatively, however, the flap  32  may be attached with security screws, such as prison screws, having the flap  32  welded to the flap hinge  40  is also one way to allow the flap  32  to lay flush against the top  28  of the dispensing unit  10  when in the closed position. The other side of the flap hinge  40  is secured to the top  28  of the dispensing unit  32  through the use of the first hinge screw  72 , the second hinge screw  74 , and the third hinge screw  76 , shown in FIG. 4, all of which may be security screws, such as prison screws. The first hinge screw  72  passes through the flap hinge  40 , through the top  28  of the dispensing unit  10 , through the safety bar  92 , and is coupled to the hinge nut  94 . Advantageously, the safety bar  92  is threaded such that if the hinge nut  94  is removed the first hinge screw  72 , the second hinge screw  74 , and the third hinge screw  76  are not readily removable. The safety bar  92  is a strip of metal with threaded holes that are positioned along the safety bar so that they can be aligned with and juxtaposed against screw holes in the top  28  of the dispensing unit  10 , and engaged by first hinge screw  72 , the second hinge screw  74 , and the third hinge screw  76 . The first hinge screw  72 , the second hinge screw  74 , and the third hinge screw  76  advantageously can be safety screws, e.g., prison screws  
         [0058]    Referring to FIG. 9 shown is a perspective view of a dispensing unit  100  for use with a liquid, such as soap and other cleaning or chemical materials. Shown is the dispensing unit  100 , the supply reservoir  12 , the supply reservoir cap  48 , the plunger  46 , the output hose  14 , an indentation  102  in the lockable door  16 , the door hasp  25 , the top  28 , the top hole  66 , the horizontal plate  50 , the first security screw  54 , the second security screw  56 , the third security screw  68 , the fourth security screw  70 , the first spacer  58 , the second spacer  60 , the first nut  62 , the second nut  64 , and the door hinge  26 .  
         [0059]    The embodiment shown in FIG. 9 is identical in all respects to the embodiment of FIG. 1, except that the flap  32  is not shown in FIG. 9 (although the flap is preferably present in the embodiment of FIG. 9) and the lockable door  16  and outlet  44  are slightly varied. Additionally, the embodiment of FIG. 9 does not have the overhang  20  as the outlet has been moved to the indentation  102  in the lockable door  16 . The indentation  102  in the lockable door  16  will be described in detail with reference to FIG. 11. The output hose  14  is shown decoupled from an outlet  104 , shown in FIG. 11, for illustration purposes.  
         [0060]    The flap  32 , described with reference to FIGS. 4, 5 and  8 , is not shown in the embodiment of FIG. 9, however, it is preferably added to this embodiment. The embodiment shown in FIG. 9 has all the tamper-proof features as the embodiment shown in FIG. 1, and such as are discussed with reference to FIGS.  1 - 8 .  
         [0061]    The supply reservoir  12  is housed within the dispensing unit  100  and is only accessible through the lockable door  16  at the front of the dispensing unit  100 . The supply reservoir  12  is only accessible when the lockable door  16  is open. The supply reservoir cap  48  is coupled to the top of the supply reservoir  12 , e.g. the supply reservoir cap  48  is screwed onto the supply reservoir  12 . The plunger  46 , such as is known in the art, and such as is described above, goes through the supply reservoir cap  48  and is coupled to the output hose  14 . The plunger  46  includes, for example, a spring that allows the plunger to be depressed (in order to pump liquid) and then return, under spring force, to the upward position.  
         [0062]    The lockable door  16  is coupled to the door frame by the door hinge  26 . The lockable door  16  has the indentation  102  formed in the front side. The lockable door  16  also preferably has a hole in the front which is aligned with the door hasp  25 , and through which the door hasp passes when the lockable door is closed, such that the lockable door  16  can be locked by placing a padlock through the door hasp  25  when the lockable door  16  is closed. The door hasp  25  is welded to an inside of the dispensing unit  100 .  
         [0063]    The top  28  of the dispensing unit  100  includes the top hole  66 . Below the top  28 , inside the dispensing unit  100  is the horizontal plate  50 . The first security screw  54 , the second security screw  56 , the third security screw  68 , and the fourth security screw  70  go through the top  28  of the dispensing unit  100  and through the horizontal plate  50 . The horizontal plate  50  is above the first spacer  58 , the second spacer  60 , the third spacer, and the fourth spacer  108  through which the first security screw  54 , the second security screw  56 , the third security screw  68 , and the fourth security screw  70  pass, respectively. The first security screw  54 , the second security screw  56 , the third security screw  68 , and the fourth security screw  70  are then coupled to the first nut  62 , the second nut  64 , a third nut and a fourth nut, respectively. Advantageously, the screws could be prison screws and the nuts could be hex nuts with nylon inserts.  
         [0064]    Referring next to FIG. 10, shown is a front partial cross-sectional view of the dispensing unit  100  of FIG. 9. Shown is the dispensing unit  100 , the supply reservoir  12 , the supply reservoir cap  48 , the plunger  46 , the output hose  14 , the indentation  102  in the lockable door  16 , the door hasp  25 , the door lock  52 , the top  28 , the horizontal plate  50 , the first security screw  54 , the second security screw  56 , the first spacer  58 , the second spacer  60 , the first nut  62 , the second nut  64 , and the door hinge  26 .  
         [0065]    Shown is the horizontal plate  50  coupled to the first security screw  54  and the second security screw  56 . The horizontal plate  50  is lying on the top of the plunger  46  such that when the horizontal plate  50  is depressed the plunger  46  is also depressed, thus causing fluid from the supply reservoir  12  to travel through the output hose  14  and out the outlet  104 , shown in FIG. 11. The first spacer  58  and the second spacer  60  are inserted above the first nut  62  and the second nut  64  but below the horizontal plate  50 . This allows the user to change the height of the spacers to adjust the amount of fluid that will be dispensed each time the horizontal plate  50  is depressed. The horizontal plate  50  also limits access to the inside of the dispensing unit  100 , thus protecting the supply reservoir  12 , the plunger  46  and the output hose  14  from vandalism.  
         [0066]    Referring next to FIG. 11, shown is a side partial cross sectional view of the dispensing unit  100  of FIG. 9. Shown is the dispensing unit  100 , the supply reservoir  12 , the supply reservoir cap  48 , the plunger  46 , the output hose  14 , the outlet  104 , the indentation  102  in the lockable door  16 , the door hasp  25 , the door lock  52 , the top  28 , the horizontal plate  50 , the second security screw  56 , the fourth security screw  70 , the second spacer  60 , the fourth spacer  108 , the second nut  64 , and a fourth nut  110 .  
         [0067]    Shown is the outlet  104  in the indentation  102  of the lockable door  16 . Also shown is the door lock  52  in the indentation  102  of the lockable door  16 . Advantageously, the door lock  52  is recessed to make it more tamper resistant. When the door lock  52  is recessed it is less susceptible to being broken. For example, an inmate in a prison trying to break the door lock  52  by striking it would be less likely to actually break the door lock  52  when it is in the recessed position as compared to the door lock  52  being positions against a flat door.  
         [0068]    The output hose  14  is coupled to both the plunger  46  and the outlet  104 . The outlet  104  is preferably a metal feed-through welded to the lockable door  16 . Advantageously the outlet  104  is not aligned vertically, but is angled slightly back toward the inside of the dispensing unit  100  to prevent the filling of large containers that do not fit within the indentation  102 , such as large buckets or garbage cans. The output hose  14  must be long enough such that when the lockable door  16  is opened the output hose  14  does not pull upon the supply reservoir  12  and tip it over. Advantageously, this also prevents excess dripping from the dispensing unit  100  as any excess fluid from the supply reservoir  12  will be caught in the output hose  14  and not drip from the outlet  104 .  
         [0069]    Referring to FIG. 12, shown is a perspective view of a dual outlet dispensing unit  120  for use with a liquid, soap and other cleaning or chemical materials. Shown is the dual outlet dispensing unit  120 , a first top hole  122 , a second top hole  124 , a first outlet  126 , a second outlet  128 , a first output hose  130 , a second output hose  132 , a first outlet shield  134 , a second outlet shield  136 , the lockable door  16 , the first door hasp  22 , the second door hasp  24 , the top hasp  36 , the side hasp  38 , the door lock  52 , the flap  140 , the flap lock  42 , the flap hinge  40 , the flap hole  34 , and an inside panel  138 .  
         [0070]    The dual outlet dispensing unit  120  has all of the tamper-proof features of the dispensing unit  10  of FIG. 1. These features are describe with reference to FIGS. 1 through 8. The dual outlet dispensing unit  120  is larger than the dispensing unit  10  of FIG. 1, as it provides for a first outlet  126 , a second outlet  128 , and two supply reservoirs  12 . Therefore, many of the structural aspects of the dispensing unit  10  of FIG. 1 are present two times in the dual outlet dispensing unit  120 , such as the horizontal plate  50 , the plunger  46 , the supply reservoir cap  48 , the supply reservoir  12 , the top hole  66 , etc.  
         [0071]    As shown there is the first top hole  122  and the second top hole  124  for controlling the output of fluid from the first outlet  126  and the second outlet  128 , respectively. The first outlet shield  134  and the second outlet shield  136  are welded on three sides and left open at the bottom, thus protecting the first outlet  126  and second outlet  128 , respectively, while allowing fluid to be dispensed. The first outlet shield  134  and the second outlet shield  136  protect the first outlet  126  and the second outlet  128  from any impact, such as an inmate kicking the dual outlet dispensing unit  120 . Advantageously, the first outlet shield  134  extends farther down past the end of the first outlet  126 , such that if an inmate placed a finger on the first outlet  126  trying to direct fluid outward from the dual output dispensing unit  120  the fluid would hit the first outlet shield  134  and not project across the room. The second outlet shield  136  acts in the same fashion. The first outlet shield  134  could also be used on the dispensing unit  10  of FIG. 1 in place of the overhang  20 . Additionally, the overhang  20  shown in FIG. 1 could be used on the dual outlet dispensing unit  120  in place of the outlet shields  134  and  136 .  
         [0072]    Advantageously, the first outlet shield  134  is made from sheet metal. The first outlet  126  is a piece of metal tubing welded to the lockable door  16 . The first outlet shield  134  is a convex portion of the lockable door  16 . The first outlet shield  134  protrudes from the lockable door  16  above the first outlet  126  and on both sides of the first outlet  126 . This forms a protective shielding around three sides of the first outlet  126 . However, the first outlet shield  134  does extend down past the bottom of the first outlet  126  such that the bottom of the first outlet shield  134  is below the piece of metal tubing making up the first outlet  126 . The first outlet shield  134  is shown extending below the first outlet  126  in FIG. 13. The bottom of the first outlet shield  134  is left open, such that the liquid can flow from the first outlet  126  and into, for example, a bucket. The second outlet shield  136  functions and is structurally the same as the first outlet shield  134 .  
         [0073]    In one embodiment the first outlet shield  134  is a piece of sheet metal that has been welded to the lockable door  16 . The first outlet shield  134  is welded to a portion of the lockable door  16  above and to both sides of the first outlet  126 . The piece of sheet metal creates a convex section in the lockable door  16 . The bottom of the first outlet shield  134  is left detached from the lockable door  16 , such that the liquid can be dispensed from the first outlet  126  into, for example, a hand held container.  
         [0074]    In another embodiment the first outlet shield  134  is in the shape of a section of a hollow cone cut along its vertical axis, as is shown in FIG. 12, however, many different shapes could be used. The inverted section of the cone is welded along both sides down to the vertex. The sides extend below the first outlet  126 , such that the circular portion of the section of the cone is below the first outlet  126 . This forms a protective shield from the top and both sides of the first outlet  126 . This protects the first outlet  126  from vandalism, such as attempting to hit or kick the first outlet  126 .  
         [0075]    The inside panel  138  is welded to the inside of the dual outlet dispensing unit  120 , and separates the two supply reservoirs inside. This prevents the supply reservoirs from being able to tip over. Additionally, the inside panel  138  prevents a larger supply reservoir from being put inside the dual outlet dispensing unit  120 . Although shown with the inside panel  138 , this is an optional feature of the dual outlet dispensing unit  120  and may be omitted, if desired.  
         [0076]    The dual outlet dispensing unit  120  also has the flap  140  that locks either in an open or closed position. The flap  140  will be larger than the flap  32  shown in FIG. 1 so that it covers both the first top hole  122  and second top hole  124 , however it functions exactly the same as the flap  32  described with reference to FIGS. 4, 5, and  8 .  
         [0077]    Referring to FIG. 13, shown is a side partial cross sectional view of the dual outlet dispensing unit  120  of FIG. 12. Shown is the dual outlet dispensing unit  120 , the supply reservoir  12 , the supply reservoir cap  48 , the plunger  46 , the second output hose  132 , the second outlet  128 , the second outlet shield  136 , the horizontal plate  50 , the flap  140 , the flap hinge  40 , the top hasp  36 , the side hasp  38 , the flap lock  42 , the first door hasp  22 , the second door hasp  24 , and the door lock  52 .  
         [0078]    Shown is the second outlet shield  136  in the shape of a nose guard. Advantageously, this allows the second outlet shield  136  to be one continuous sheet of metal welded to the lockable door  16 . However, the second outlet shield  136  could be any shape that protects the second outlet  128  from damage. For example, the second outlet  128  is protected from an inmate kicking or hitting the second outlet  128  by the second outlet shield  136 .  
         [0079]    Referring to FIG. 14, shown is a side partial cross sectional view of a base outlet dispensing unit  150 . Shown is the base outlet dispensing unit  150 , the supply reservoir  12 , the supply reservoir cap  48 , the plunger  46 , the output hose  14 , the outlet  152 , a retaining band  153 , an inner shield  154 , the flap lock  42 , the door lock  52 , the first door hasp  22 , the second door hasp  24 , the horizontal plate  50 , the top hasp  36 , the side hasp  38 , the flap  32 , and the flap hinge  40 .  
         [0080]    The lockable door  16 , the flap  32 , the horizontal plate  50 , the plunger  46 , the supply reservoir cap  48 , and the supply reservoir  12 , are functionally and structurally the same as the embodiment of FIG. 1. The details of these aspects of the embodiment of FIG. 14 are described in detail with reference to FIGS.  1 - 8 .  
         [0081]    A base hole  162 , similar to the one shown in FIG. 15, in the base outlet dispensing unit  150  is where fluid will be dispensed. Shown is the inner shield  154 , welded to the inside of the base outlet dispensing unit  150  between the supply reservoir  12  and the base hole  162 . The inner shield  154  is preferable an “L”-shaped metal piece and is juxtaposed with a corner of the base outlet dispensing unit  150  to form a hollow vertical passage at a base of which is positioned the base hole  162 , which may be round. The outlet  152  is a metal tube that is coupled to the side of the base outlet dispensing unit  150  by the retaining band  153  that holds it in place. The output hose  14  is coupled to the outlet  152  and the plunger  46 . The outlet  152  is aligned directly above the base hole  162 , such that fluid will leave the outlet  152  and fall, by gravity, through the passage formed by the inner shield  154 , and then through the base hole  162 .  
         [0082]    When the horizontal plate  50  is depressed fluid travels through the output hose  14  and out the outlet  152 . The fluid then falls through the base hole  162  and preferably into a mop bucket or other container. The base outlet dispensing unit  150  could also be placed above a sink, such that dishwashing liquid would fall directly into the sink. The outlet  152  is positioned above the supply reservoir  12  such that excess fluid will not drip from the outlet  152 . The air gap between the outlet  152  and the base hole  162  also prevents dripping. If the output hose  14  were to extend the entire length to the base hole  162  excess fluid would drip from the outlet  152  after the desired amount of fluid has already been dispensed.  
         [0083]    The inner shield  154  forms a protective barrier between the base hole  162  and the supply reservoir  12 . The inner shield  154  should be as tall as necessary depending on the application. For example, in a jail or correctional facility, the inner shield  154  should be tall enough such that if an inmate could stick a finger up through the base hole  162 , he or she could not access the supply reservoir  12 . This prevents an inmate who sticks his finger up through the base hole  162  from being able to touch the supply reservoir  12  or output hose  14 , thus preventing harm to the supply reservoir  12  and the output hose  14 .  
         [0084]    Referring to FIG. 15, shown is a perspective view of a combination outlet dispensing unit  160  for use with a liquid, soap and other cleaning or chemical materials. Shown is the combination outlet dispensing unit  160 , the first top hole  122 , the second top hole  124 , the base hole  162 , an outlet shield  172 , a first outlet  168 , a first outlet hose  164 , a second outlet  170 , a second outlet hose  166 , the flap  140 , the flap hinge  40 , the flap lock  42 , the top hasp  36 , the side hasp  38 , the door lock  52 , the first door hasp  22 , the second door hasp  24 , the lockable door  16 , and the inside panel  138 .  
         [0085]    Shown is the combination outlet dispensing unit  160  similar to the dual outlet dispensing unit  120  of FIG. 12. However, one side of the dual outlet dispensing unit  120  has been replaced by the base outlet dispensing unit  150  of FIG. 14. The combination outlet dispensing unit  160  has all the features described with reference to FIGS. 1 through 14. The first outlet  168  is the same as the outlet described in FIG. 14, while the second outlet  170  and the outlet shield  172  are described in detail with reference to FIGS. 12 and 13. The flap  140  is also described with reference to FIG. 12.  
         [0086]    When the horizontal plate  50  below the first top hole  122  is depressed fluid will flow from the first outlet  168  and out through the base hole  162 . If the horizontal plate below the second top hole  124  is depressed fluid will flow from the second outlet  170 .  
         [0087]    Advantageously, the combination outlet dispensing unit  160  could be used to fill both hand held containers and buckets. The base hole  162  could be used to fill buckets or dispense directly into a sink, while the second outlet  170  with the outlet shield  172  could be used for hand soap or to fill hand held containers such as spray bottles with fluid.  
         [0088]    Referring to FIG. 16, shown is a perspective view of a combinational outlet dispensing unit  180  for use with a liquid, soap and other cleaning or chemical materials. Shown is the combination outlet dispensing unit  180 , the first top hole  122 , the second top hole  124 , an outlet shield  172 , a first outlet  174 , a first outlet hose  176 , a second outlet  170 , a second outlet hose  166 , the flap  140 , the flap hinge  40 , the flap lock  42 , the top hasp  36 , the side hasp  38 , the door lock  52 , the first door hasp  22 , the second door hasp  24 , a door indentation  178 , the lockable door  16 , and the inside panel  138 .  
         [0089]    Shown is the combination outlet dispensing unit  180  similar to the dual outlet dispensing unit  120  of FIG. 12. However, one side of the dual outlet dispensing unit  120  has been replace by the outlet system of FIG. 9. The combination outlet dispensing unit  180  has all the features described with reference to FIGS. 1 through 15. The first outlet  174  is the same as the outlet described in FIGS. 9 through 11, while the second outlet  170  and the outlet shield  172  are described in detail with reference to FIGS. 12 and 13. The flap  140  is also described with reference to FIG. 12.  
         [0090]    The combination outlet dispensing unit  180  has the indentation  178  in the lockable door  16  with the first outlet  174  slightly angled toward the back of the indentation  178 . The first outlet and indentation allow a user to fill up a container as long as it fits into the indentation, such as a hand held container. This prevents a user from filling up a large bucket from the first outlet  174 . The indentation  178  is further described with reference to FIGS. 9 through 11. The combination outlet dispensing unit  180  could be used above a sink, such that the second outlet  170  is used for dish or hand soap that could drop directly into the sink and the first outlet  174  would be used to fill small containers.  
         [0091]    While the invention herein disclosed has been described by means of specific embodiments and applications thereof, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope of the invention set forth in the claims.
