CROSS REFERENCE TO RELATED APPLICATIONS

   TECHNICAL FIELD 
   The present invention generally relates to fluid dispensing apparatus and more particularly to a portable manually operated fluid dispenser and applicator for the selective application of a specific fluid to a desired location. 
   BACKGROUND OF INVENTION 
   There are a variety of fluid dispensers in the prior art. Fluid dispenser components typically comprise: a reservoir, a means for regulating fluid flow, and an applicator. The reservoir contains a fluid and also has a means for motivating the fluid to communicate into the means for regulating the fluid flow and further communicating to the applicator. The means for motivating the fluid out of the reservoir can be anything from simply using gravity to having a means for increasing the pressure of the fluid in the reservoir thus motivating the fluid to flow out of the reservoir through the means for regulating the fluid flow and onward to the applicator. The means for motivating the fluid out of the reservoir outside of simply using gravity can include using a movable piston inside of a close fitting bore such as in a hypodermic needle, or having a reservoir constructed of a resilient material wherein the reservoir is compressed in some manner to reduce its interior volume thus raising the pressure of the fluid in the reservoir. The means for regulating the fluid flow can include simply having a selectively sized fluid flow passageway, or a valve of some type. The applicator portion of the fluid dispenser can include a pen quill, a hollow needle being a cannula with a lumen, a brush with bristles, or a sponge type material, and the like. 
   There are many issues surrounding the fluid dispenser, such as accurate controlling of the measured volumes of the fluid dispensed, how to handle the many different types of fluids and their properties, such as viscosity, miscibility of the various fluid components, and the drying or hardening characteristics of the fluid as it flows through the applicator and onto the desired surface, area, or volumemetric cavity at the desired location. Other issues for fluid dispensers would include fluid waste, spillage, leakage, and reuse of the fluid dispenser after a period of inactivity wherein the fluid may dry or harden in or on any of the fluid dispenser components. Typically, once the fluid leaves the sealed reservoir it is exposed to atmospheric air wherein the fluid&#39;s volatile compounds start to evaporate and initiate the fluid drying or hardening process which may cause fluid communication problems for the fluid dispenser components being the means to regulate fluid flow and the applicator as the fluid viscosity greatly increases and can essentially cause the fluid dispenser to become inoperative. Also, another issue is the communication of the fluid to the applicator itself, such as with a conventional brush that is dipped into a fluid wherein the fluid is deposited all over the brush which typically causes an excess amount of fluid on the brush requiring at least one brush stroke to remove excess fluid from the brush before use, with typically only one side of the brush which will be applied to the surface and the like. In addition, reservoir breakage and accidental discharge of the fluid can be problems while the fluid dispenser is in use. 
   In addressing the above-identified issues that are common to fluid dispensers, the prior art discloses a number of different types of apparatus. Starting with the at accurate controlling of the measured volume of fluid to be dispensed, a common solution is to utilize a movable piston in a close fitting bore while closely controlling the axial movement of the piston with graduations marked on the outside of a translucent of clear bore, thus controlling the axial displacement or volume reduction in the reservoir as is common with a hypodermic needle assembly. Another method of controlling the volume of the fluid to be dispensed is to simply size the reservoir volumetrically to contain the desired volume of fluid to be dispensed, which would make the reservoir a single use system that may be disposable if it is not refillable, such as with a common eyedropper assembly. A further method of controlling the volume of fluid to be dispensed is to use a resilient reservoir having an additional apparatus of mechanical stops or a control upon the amount of resilient reservoir volume reduction, such as disclosed in U.S. Pat. No. 5,186,563 to Gebhard et al. and U.S. Pat. No. 4,944,625 to Futter et al. The complexity of the apparatus to control the volume of fluid to be dispensed depends to a large degree upon the volumetric accuracy required, with the piston and bore apparatus being substantially the most accurate, however, having a higher cost to manufacture and also having the attendant disadvantage of requiring a close fitting dynamic fluid seal between the piston and the bore. Also, utilizing a specifically sized volume of reservoir to dispense a selected amount of fluid can result in material waste in the form of making the reservoirs&#39; individually disposable for a single use, or adding additional apparatus to make the reservoir refillable for multiple uses from one reservoir. The use of a resilient reservoir is appealing due to lower cost and simplicity; however, the addition of apparatus to create some sort of mechanical stop or stops can also add complexity and cost to the fluid dispenser assembly. 
   Further, looking to the fluid dispenser issue of controlling or the regulating the flow of the fluid as it exits the reservoir and communicates to the applicator, the prior art typically utilizes a valve of some type as is typically disclosed in U.S. Pat. No. 4,470,715 to Reuchlin et al., U.S. Pat. No. 6,056,470 to Nchashi et al., and U.S. Pat. No. 6,402,410 to Hall et al. Alternatively, a fluid flow restriction such as an orifice or the lumen inside of the cannula wherein the fluid dispensed must flow through the orifice or the lumen inside of the cannula is disclosed in U.S. Pat. No. 1,945,957 to Salmon and U.S. Pat. No. 1,935,639 to Keeshan. Obviously, for simplicity the orifice or the lumen would be the most attractive apparatus use for controlling and regulating the flow of fluid, however, the disadvantage of the orifice or the lumen would be the lack of the ability to substantially stop the flow of a fluid when it is desired to prevent spillage or leakage. The use of a valve can accommodate this requirement, however, a valve adds a degree of mechanical complexity that is generally undesirable. The prior art has recognized this problem and has attempted to solve it by making the reservoir and the means for controlling and regulating the flow of fluid as separable pieces, creating the ability to separately clean the means for controlling and regulating the flow of fluid, such as typically disclosed in U.S. Pat. No. 4,447,169 to Vartoughian. Adding the requirement that if the means for controlling and regulating the flow of fluid were removed from the reservoir requires that the reservoir outlet would have to be sealable, which of course again requires a valve or cap to substantially seal reservoir outlet as disclosed in U.S. Pat. No. 3,969,028 to Negreiros, U.S. Pat. No. 3,592,202 to Jones, and U.S. Pat. No. 5,975,088 to Stehman. This causes the attendant problems of when the fluid dries or hardens after exposure to atmospheric air, the valve or the cap will tend to gum up or stick causing difficulty in initiating reuse of the fluid dispenser for having the fluid flow out of the reservoir outlet and into the means for regulating fluid flow, and finally to the applicator. 
   What is needed is a fluid dispenser that overcomes the previously identified issues related to fluid dispensers, being selectable volumes of fluid to dispense from the reservoir, the means of controlling or regulating the fluid flow, having reduced susceptibility to the fluid drying or hardening from exposure to atmospheric air, the method of applying the fluid to the applicator, and having the reservoir separable from the means of controlling the regulating the fluid flow. While at the same time keeping the objectives of simplicity, function and minimal manufacturing cost paramount. This requires a reservoir that has an easily controllable interior volume adjustment with reduced risk of rupture, breakage, or leakage of the reservoir fluid and with the reservoir having a resealable outlet that minimizes the problems of the fluid drying or hardening that would restrict the fluid communicating from the reservoir outlet that is caused from the fluid being exposed to atmospheric air while the same time reducing the risk of accidental spillage of the fluid from the reservoir. Also, this would require that the means of controlling and regulating the fluid flow would deposit the fluid to an interior portion of the applicator thus minimizing the need for removal of excess fluid from the applicator prior to use.

   DETAILED DESCRIPTION 
   With initial reference to  FIGS. 1 and 2 ,  FIG. 1  shows a perspective view of the fluid dispenser  20  assembly from the applicator  47  side and  FIG. 2  shows a perspective view of the fluid dispenser assembly  20  from the first end sealing cap  28  side. The fluid dispenser  20  is designed to allow the user to manually apply a selected fluid to a desired location by the user and comprises two major elements, being a reservoir assembly  22  and the applicator assembly  47 . The reservoir assembly  22  that is able to contain the selected fluid includes a resilient body portion  24  that has a resilient body portion first end  25  and a resilient body portion second end  31 . The reservoir assembly  22  also includes a first end sealing cap  28  and a second end sealing cap assembly  33  that includes a second end-sealing cap  30  that acts in conjunction with the resilient body portion  24  to define a reservoir interior that is not shown in  FIGS. 1 and 2 . The resilient body portion  24  has a bellows  26  that is oriented to retract or extend the resilient body portion  24  between the resilient body portion first end  25  and the resilient body portion second end  31  with the result that a variable reservoir interior volume is possible. The second end-sealing cap  30  also includes a penetrable elastomeric member retainer  34 , a penetrable elastomeric member support  32 , and a penetrable elastomeric member that is not shown in  FIGS. 1 and 2 . The fluid dispenser assembly  20  also includes the applicator assembly  47  that is comprised of a proximal end  98  and a distal end  100 . The proximal end  98  includes a penetrating non-coring cannula adapter assembly  37  that also includes a penetrating non-coring cannula, a penetrating and non-coring cannula adapter body rim  48 , and a non-coring cannula with a lumen that is not shown in  FIGS. 1 and 2 . The distal end  100  includes an application element cannula body  52  and an application element assembly  51 . The application element assembly  51  is comprised of an application element retainer  60 , an application element  62  that is depicted in  FIGS. 1 and 2  as an application element in the form of a brush element  96  with brush element bristles  97 . 
   Turning next to  FIG. 3  shown is an exploded cross sectional view of the fluid dispenser assembly  20  elements, broadly being the reservoir assembly  22  and an applicator assembly  47  that includes the penetrating non coring cannula adapter assembly  37  and the application element assembly  51 .  FIG. 7  shows the exploded cross section view of  FIG. 3  assembled comprising the fluid dispenser assembly  20 . The reservoir assembly  22  that is able to contain the selected fluid includes a resilient body portion  24  that has a resilient body portion first end  25  and a resilient body portion second end  31 . The reservoir assembly  22  also includes a first end sealing cap  28  and a second end sealing cap assembly  33  that includes a second end sealing cap  30  that acts in conjunction with the resilient body portion  24  to define a reservoir interior  35 . The resilient body portion  24  has a bellows  26  that is oriented to retract or extend the resilient body portion  24  between the resilient body portion first end  25  and the resilience body portion second end  31  with the result that a variable reservoir interior volume  35  is possible. As shown in  FIGS. 3 and 7  the bellows  26  is in a bellows extended position state  27 . The second end sealing cap  30  also includes a penetrable elastomeric member retainer  34 , a penetrable elastomeric member support  32 , and a penetrable elastomeric member  36 . There is also included an applicator support element  88  that is secured between the reservoir assembly  22  and the applicator assembly  47 . The applicator support element  88  is intended to provide additional support to the applicator assembly  47  attachment to the reservoir assembly  22  being secured between the reservoir assembly  22  and the applicator assembly  47 , wherein the interface of the penetrating non coring cannula body  38  and the penetrable elastomeric member  36  after the penetrating non coring cannula body  38  has been inserted and penetrated through the penetrable elastomeric member  36  provides an inadequately rigid attachment between the applicator assembly  47  and the reservoir assembly  22 . The form of the applicator support element  88  can be either internal or external to the reservoir assembly  22 .  FIGS. 3 and 7  show the applicator support element  88  to be internally mounted, thus residing in the reservoir interior  35 , with the applicator support element  88  having a slidable or removable engagement with the penetrating non coring cannula body  38 , thus providing extra support rigidity for the attachment between the reservoir assembly  22  and the applicator assembly  47 . However, the applicator support element  88  could just as well be mounted on the exterior of the reservoir assembly  22  being secured between the second end sealing cap assembly  33  and the penetrating non coring cannula adapter assembly  37  of the applicator assembly  47 , wherein the applicator support element  88  would be removably engagable on either or both the second end the sealing cap assembly  33  and the penetrating non coring cannula adapter assembly  37  of the applicator assembly  47 . 
   The materials of construction for the resilient body portion  24  are preferably a resilient synthetic plastic, however, the resilience synthetic plastic could be constructed of materials selected from a group consisting essentially of polyethylene, polypropylene, or polyurethane materials all of which would be preferably compatible with the selected fluid. It may also be desirable for the resilient body portion  24  to be constructed of a translucent or clear material to allow the selected fluid that is contained in the reservoir assembly  22  interior volume  35  to be viewed by the user of the fluid dispenser assembly  20 , thus allowing the user to ascertain both the quantity of selected fluid in the interior volume  35  and the color of the selected fluid in the interior volume  35 . The materials of construction for the first end sealing cap  28 , the second end sealing cap  30 , penetrable elastomeric member support  32 , applicator support element  88 , and penetrable elastomeric member retainer  34  can be constructed of any material that is preferably compatible with the selected fluid. The materials of construction for the penetrable elastomeric member  36  should be in addition to being preferably compatible with the selected fluid have a resiliency to allow for a substantially fluid tight seal between the penetrable elastomeric member  36  and a penetrating non coring cannula body  38  when a penetrating non coring cannula body  38  with the penetrating non coring cannula insertion end  43  is inserted and penetrated through the penetrable elastomeric member  36  and protruding into the reservoir interior  35 . In addition, the materials of construction for the penetrable elastomeric member  36  should allow for a substantially fluid tight seal when the penetrating non-coring cannula insertion end  43  is removed from the penetrable elastomeric member  36 . In total, the materials of construction for the reservoir assembly are also preferably non-breakable thus helping to preclude a user accidentally breaking or rupturing the reservoir assembly  22  thus spilling the selected fluid. 
   The fluid dispenser assembly  20  also includes the applicator assembly  47  that is comprised of a proximal end  98  and a distal end  100 . The proximal end  98  includes a penetrating non-coring cannula adapter assembly  37  that includes a penetrating non-coring cannula assembly  39 . The penetrating non-coring cannula assembly  39  comprises a penetrating non-coring cannula body  38  with a penetrating non-coring cannula lumen  44 , and a penetrating non-coring cannula insertion end  43 . The penetrating non coring cannula insertion end  43  is adapted to insert and penetrate through the penetrable elastomeric member  36  and protrude into the reservoir interior  35  to enable fluid communication between the reservoir interior  35  and the non coring cannula lumen  44 . The side of the penetrating non coring cannula body  38  opposite of the penetrating non coring cannula insertion end  43  has a penetrating non coring cannula adapter body  46  that terminates in a penetrating non coring cannula adapter body rim  48  and a penetrating non coring cannula adapter aperture  50  that is in fluid communication with the penetrating non coring cannula lumen  44 . The distal end  100  includes an application element cannula body  52  with an application element cannula lumen  58  with the application element cannula body  52  including an application element cannula adapter end  54  and an application element cannula discharge end  56 . The application element cannula discharge end  56  includes an application element retainer  60  and an application element  62 , which in  FIG. 3  is an application element in the form of a brush element  96  with brush element bristles  97 . The penetrating non-coring cannula adapter aperture  50  is in fluid communication with the application element cannula lumen  58  that is in fluid communication with the application element  62 . 
   The materials of construction for the penetrating non coring cannula body  38 , the penetrating non coring cannula adapter body  46 , the penetrating non coring cannula adapter body rim  48 , the application element cannula body  52 , the application element retainer  60 , and application element  62  can be constructed of any material that is preferably compatible with the selected fluid. 
   Although  FIG. 3  shows the applicator assembly  47  in two separable pieces being the penetrating non coring cannula adapter assembly  37  and the application element assembly  51 , it is possible that the applicator assembly  47  could be a single piece having a continuous fluid communication from the penetrating non coring cannula lumen  44  to the application element cannula lumen  58 . As shown in  FIG. 3  with the applicator assembly  47  being in two separable pieces, being the penetrating non coring cannula adapter assembly  37  and the application element assembly  51 , the application element cannula adapter end  54  and the penetrating non coring cannula adapter aperture  50  are matingly engagable in a substantially fluid type manner. This is to allow the application element assembly  51  to be interchangeable. 
   Further, to  FIGS. 4 ,  5 , and  6  shown are detailed cross section views and a perspective view of the penetrating non-coring cannula assembly  39 , specifically detailing the penetrating non-coring cannula insertion end  43 . The penetrating non coring cannula body  38  includes a penetrating non coring cannula lumen  44 , a longitudinal axis of the lumen  45 , a penetrating non coring cannula aperture  42 , a penetrating non coring cannula taper  41 , and a penetrating non coring cannula nose tip  40 . The penetrating non coring cannula taper  41  goes from the penetrating non coring cannula body  38  to the penetrating non coring cannula nose tip  40 . The purpose of the penetrating non coring cannula assembly  39 , specifically detailing the penetrating of the non coring cannula insertion end  43  is to prevent cutting and or coring of the penetrable elastomeric member  36  when the penetrating non coring cannula insertion end  43  is inserted and penetrated through the penetrable elastomeric member  36 . This prevents removal of material from the penetrable elastomeric member  36  that could interfere with the ability of the penetrable elastomeric member  36  being able to substantially form a fluid tight seal when the penetrating non coring cannula insertion end  43  of the penetrating non coring cannula assembly  39  is removed from the penetrable elastomeric member  36 . In addition, if the penetrating non coring cannula insertion end  43  generated debris from cutting and or coring of the penetrable elastomeric member  36  when the penetrating non coring cannula insertion end  43  is inserted and penetrated through the and penetrable elastomeric member  36  there is a risk that these debris could lodge in the penetrating non coring cannula lumen  44  and potentially obstruct flow of the selected fluid in the penetrating non coring cannula lumen  44 . 
   Also, there is an inherent degree of additional safety with the penetrating non coring cannula insertion end  43  having the penetrating non coring cannula nose tip  40  being blunt and not sharp to minimize risk to the user of accidentally pricking a finger and the like. The penetrating non coring cannula aperture  42  is oriented substantially transverse to the longitudinal axis of the lumen  45  with the penetrating non coring cannula aperture  42  and the penetrating non coring cannula lumen  44  being in fluid communication. The penetrating non coring cannula aperture  42  is positioned within the penetrating non coring cannula insertion end  43  or being inboard of the penetrating non coring cannula nose tip  40 . This is to create a blunt solid cannula nose tip  40  on the penetrating non coring cannula insertion end  43  with the effect of the penetrating non coring cannula lumen  44  terminating inboard of the penetrating non coring cannula nose tip  40  to prevent cutting and coring of the penetrable elastomeric member  36 , while the penetrating non coring cannula insertion end  43  is inserted and penetrated through the penetrable elastomeric member  36 . 
   As the penetrating non coring cannula insertion end  43  has the penetrating non coring cannula nose tip  40  being blunt and not sharp creates the requirement that the penetrable elastomeric member  36  be pre pierced to accommodate the penetrating non coring cannula insertion end  43  and the penetrating non coring cannula nose tip  40  being able to insert and penetrate the penetrable elastomeric member  36  without removal of material from the penetrable elastomeric member  36 . The pre piercing of the penetrable elastomeric member  36  is preferably accomplished by producing a slit in the penetrable elastomeric member  36  therethrough, with the size of the slit being slightly larger than the outside diameter of the penetrating non coring cannula body  38  which will allow passage of the penetrating non coring cannula insertion end  43  to allow fluid communication between the reservoir interior  35  and the penetrating non coring cannula aperture  42  while maintaining a substantially fluid tight seal between the penetrable elastomeric member  36  and the outside diameter of the penetrating non coring cannula body  38 . Also, with the penetrable elastomeric member  36  maintaining a substantially fluid tight seal at the slit with the penetrating non coring cannula insertion end  43  and penetrating non coring cannula body  38  removed from the penetrable elastomeric member  36 . This allows multiple insertions and removals&#39; of the penetrating non coring cannula assembly  39  into and from the penetrable elastomeric member  36  while maintaining either fluid communication from the reservoir interior  35  through the penetrating non coring cannula aperture  42  and into the penetrating non coring cannula lumen  44  or having the reservoir interior  35  reseal at the slit that is within the penetrable elastomeric member  36  respectively with the penetrating non coring cannula assembly  39  is removed from the penetrable elastomeric member  36 . 
   Further, referencing ahead to  FIGS. 17 ,  18 , and  19  shown is an alternative cannula with a lumen therethrough for use with the fluid dispenser assembly  20 , that is detailed in cross section views and a perspective view of the penetrating non-coring cannula body with lumen therethrough assembly  116 , specifically detailing the penetrating non-coring cannula body with lumen therethrough insertion end  118 . The penetrating non coring cannula body with lumen therethrough  106  includes a penetrating non coring cannula lumen therethrough  108 , a longitudinal axis of the lumen therethrough  114 , a penetrating non coring cannula with lumen therethrough body taper  112 , and a penetrating non coring cannula with lumen therethrough rounded nose ridge  110 . The penetrating non coring cannula with lumen therethrough body taper  112  goes from the penetrating non coring cannula body with lumen therethrough  106  to the penetrating non coring cannula with lumen therethrough rounded nose ridge  110 . The purpose of the penetrating non-coring cannula body with lumen therethrough assembly  116 , specifically detailing the penetrating of the penetrating non coring cannula with lumen therethrough rounded nose ridge  110  is to prevent cutting and or coring of the penetrable elastomeric member  36  when the penetrating non-coring cannula body with lumen therethrough insertion end  118  is inserted and penetrated through the penetrable elastomeric member  36 . This prevents removal of material from the penetrable elastomeric member  36  that could interfere with the ability of the penetrable elastomeric member  36  being able to substantially form a fluid tight seal when the penetrating non-coring cannula body with lumen therethrough insertion end  118  of the penetrating non-coring cannula body with lumen therethrough assembly  116  is removed from the penetrable elastomeric member  36 . In addition, if the penetrating non-coring cannula body with lumen therethrough insertion end  118  generated debris from cutting and or coring of the penetrable elastomeric member  36  when the penetrating non-coring cannula body with lumen therethrough insertion end  118  is inserted and penetrated through the and penetrable elastomeric member  36  there is a risk that these debris could lodge in the penetrating non coring cannula lumen therethrough  108  and potentially obstruct flow of the selected fluid in the penetrating non coring cannula lumen therethrough  108 . 
   Also, there is an inherent degree of additional safety with the penetrating non-coring cannula body with lumen therethrough insertion end  118  having the penetrating non coring cannula with lumen therethrough rounded nose ridge  110  being blunt and not sharp to minimize risk to the user of accidentally pricking a finger and the like. 
   As the penetrating non-coring cannula body with lumen therethrough insertion end  118  has the penetrating non coring cannula with lumen therethrough rounded nose ridge  110  being blunt and not sharp creates the requirement that the penetrable elastomeric member  36  be pre pierced to accommodate the penetrating non-coring cannula body with lumen therethrough insertion end  118  and the penetrating non coring cannula with lumen therethrough rounded nose ridge  110  being able to insert and penetrate the penetrable elastomeric member  36  without removal of material from the penetrable elastomeric member  36 . The pre piercing of the penetrable elastomeric member  36  is preferably accomplished by producing a slit in the penetrable elastomeric member  36  therethrough, with the size of the slit being slightly larger than the outside diameter of the penetrating non coring cannula body with lumen therethrough  106  which will allow passage of the penetrating non-coring cannula body with lumen therethrough insertion end  118  to allow fluid communication between the reservoir interior  35  and the penetrating non coring cannula lumen therethrough  108  while maintaining a substantially fluid tight seal between the penetrable elastomeric member  36  and the penetrating non coring cannula body with lumen therethrough  106 . Also, with the penetrable elastomeric member  36  maintaining a substantially fluid tight seal at the slit with the penetrating non-coring cannula body with lumen therethrough insertion end  118  and penetrating non coring cannula body with lumen therethrough  106  removed from the penetrable elastomeric member  36 . This allows multiple insertions and removals&#39; of the penetrating non-coring cannula body with lumen therethrough assembly  116  into and from the penetrable elastomeric member  36  while maintaining either fluid communication from the reservoir interior  35  through the penetrating non coring cannula lumen therethrough  108  or having the reservoir interior  35  reseal at the slit that is within the penetrable elastomeric member  36  respectively with the penetrating non-coring cannula body with lumen therethrough assembly  116  is removed from the penetrable elastomeric member  36 . 
   Next, further to  FIG. 8  shown is a cross section view of the fluid dispenser assembly  20  in use with a selected fluid  64  communicating from the reservoir assembly  22  to the applicator assembly  47  that includes an application element assembly  51  with the application element in the form of a brush element  96 . The reservoir assembly  22  that is able to contain the selected fluid  64  includes a resilient body portion  24  that has a resilient body portion first end  25  and a resilient body portion second end  31 . The reservoir assembly  22  also includes a first end sealing cap  28  and a second end sealing cap assembly  33  that includes a second end sealing cap  30  that acts in conjunction with the resilient body portion  24  to define a reservoir interior  35 . The resilient body portion  24  has a bellows  26  that is oriented to retract or extend the resilient body portion  24  between the resilient body portion first end  25  and the resilience body portion second end  31  with the result that a variable reservoir interior volume  35  is possible. The bellows  26  is in a bellows retracted position state  29 . The second end sealing cap  30  also includes a penetrable elastomeric member retainer  34 , a penetrable elastomeric member support  32 , and a penetrable elastomeric member  36 . 
   There is also included an applicator support element  88  that is secured between the reservoir assembly  22  and the applicator assembly  47 . The applicator support element  88  is intended to provide additional support to the applicator assembly  47  attachment to the reservoir assembly  22  being secured between the reservoir assembly  22  and the applicator assembly  47 . Wherein the interface of the penetrating non coring cannula body  38  and the penetrable elastomeric member  36  after the penetrating non coring cannula body  38  has been inserted and penetrated through the penetrable elastomeric member  36  provides an inadequately rigid attachment between the applicator assembly  47  and the reservoir assembly  22 . The form of the applicator support element  88  can be either internal or external to the reservoir assembly  22 .  FIG. 8  shows the applicator support element  88  to be internally mounted, thus residing in the reservoir interior  35 , with the applicator support element  88  having a slidable or removable engagement with the penetrating non coring cannula body  38 , thus providing extra support rigidity for the attachment between the reservoir assembly  22  and the applicator assembly  47 . However, the applicator support element  88  could just as well be mounted on the exterior of the reservoir assembly  22  being secured between the second end sealing cap assembly  33  and the penetrating non coring cannula adapter assembly  37  of the applicator assembly  47 , wherein the applicator support element  88  would be removably engagable on either or both the second end the sealing cap assembly  33  and the penetrating non coring cannula adapter assembly  37  of the applicator assembly  47 . 
   The materials of construction for the resilient body portion  24  are preferably a resilient synthetic plastic, however, the resilient synthetic plastic could be constructed of materials selected from a group consisting essentially of polyethylene, polypropylene, or polyurethane materials all of which would be preferably compatible with the selected fluid  64 . It may also be desirable for the resilient body portion  24  to be constructed of a translucent or clear material to allow the selected fluid  64  that is contained in the reservoir assembly  22  interior volume  35  to be viewed by the user of the fluid dispenser assembly  20 , thus allowing the user to ascertain both the quantity of selected fluid in the interior volume  35  and the color of the selected fluid in the interior volume  35 . The materials of construction for the first end sealing cap  28 , the second end sealing cap  30 , penetrable elastomeric member support  32 , applicator support element  88 , and penetrable elastomeric member retainer  34  can be constructed of any material that is preferably compatible with the selected fluid  64 . The materials of construction for the penetrable elastomeric member  36  should be in addition to being preferably compatible with the selected fluid  64  have a resiliency to allow for a substantially fluid tight seal between the penetrable elastomeric member  36  and the penetrating non coring cannula body  38  when the penetrating non coring cannula body  38  penetrating non coring cannula insertion end  43  is inserted and penetrated through the penetrable elastomeric member  36  and protrudes into the reservoir interior  35 . In addition, the materials of construction for the penetrable elastomeric member  36  should allow for a substantially fluid tight seal when the penetrating non-coring cannula insertion end  43  is removed from the penetrable elastomeric member  36 . 
   In use, the reservoir assembly  22  may be supplied to the user without the selected fluid  64 , in other words the reservoir interior  35  would be emptied being devoid of the selected fluid  64 . Alternatively, the reservoir assembly  22  may have the reservoir interior volume  35  sized to the pre filled with the selected fluid  64  allowing the user to insert the applicator assembly  47  into the penetrable elastomeric member  36  and subsequently having multiple uses of the fluid dispenser  20 , which may be with a single insertion of the applicator assembly  47  into the penetrable elastomeric member  36  or with multiple insertions and removals&#39; of the applicator assembly  47  into and out of the penetrable elastomeric member  36 , that would allow cleaning or changing of the applicator assembly  47 . This helps to keep the selected fluid  64  from drying out or hardening in the reservoir assembly  22 , and also helps in preventing spills and leakage of the selected fluid  64  from the reservoir assembly  22 . Also, the reservoir assembly  22  may have the reservoir interior volume  35  sized to be prefilled with a specific volume of the selected fluid  64  allowing the user to insert the applicator assembly  47  into the penetrable elastomeric member  36  and subsequently having a single use of the fluid dispenser  20 . The fluid dispenser assembly  20  may be set up for multiple uses with a cleanable applicator assembly  47  or multiple applicator assemblies  47 , or may be set up for and single use with either the applicator assembly  47  being disposable, the reservoir assembly  22  being disposable or both the applicator assembly  47  and the reservoir assembly  22  being disposable. 
   The fluid dispenser assembly  20  also includes the applicator assembly  47  that is comprised of a proximal end  98  and a distal end  100 . The proximal end  98  includes a penetrating non-coring cannula adapter assembly  37  that includes a penetrating non-coring cannula assembly  39 . The penetrating non-coring cannula assembly  39  comprises a penetrating non-coring cannula body  38  with a penetrating non-coring cannula lumen  44 , and a penetrating non-coring cannula insertion end  43 . The penetrating non coring cannula insertion end  43  is adapted to insert and penetrate through the penetrable elastomeric member  36  and protrude into the reservoir interior  35  to enable fluid communication between the reservoir interior  35  and the non coring cannula lumen  44 . The flowrate of the selected fluid  64  may be controlled by the non coring cannula lumen  44  that can be sized by a flow restriction through either controlling the inside diameter of the non coring cannula lumen  44  or by the use of an orifice restriction positioned adjacent to and in fluid communication with the non coring cannula lumen  44  using generally known flow restriction and orifice fluid flow calculations depending upon the selected fluid  64  properties such as density, viscosity, and the like. The side of the penetrating non coring cannula body  38  opposite of the penetrating non coring cannula insertion end  43  has a penetrating non coring cannula adapter body  46  that terminates in a penetrating non coring cannula adapter body rim  48  and a penetrating non coring cannula adapter aperture  50  that is in fluid communication with the penetrating non coring cannula lumen  44 . The distal end  100  includes an application element cannula body  52  with an application element cannula lumen  58  with the application element cannula body  52  including an application element cannula adapter end  54  and an application element cannula discharge end  56 . The application element cannula discharge end  56  includes an application element retainer  60  and an application element  62  which in  FIG. 8  is an application element in the form of a brush element  96  with brush element bristles  97 . The penetrating non-coring cannula adapter aperture  50  is in fluid communication with the application element cannula lumen  58  that is in fluid communication with the application element  62 . 
   The materials of construction for the penetrating non coring cannula body  38 , the penetrating non coring cannula adapter body  46 , the penetrating non coring cannula adapter body rim  48 , the application element cannula body  52 , the application element retainer  60 , and application element  62  can be constructed of any material that is preferably compatible with the selected fluid  64 . 
   Although  FIG. 8  shows the applicator assembly  47  in two separable matingly engagable pieces being the penetrating non coring cannula adapter assembly  37  and the application element assembly  51 , it is possible that the applicator assembly  47  could be a single piece having a continuous fluid communication from the penetrating non coring cannula lumen  44  to the application element cannula lumen  58 . As shown in  FIG. 8  with the applicator assembly  47  being in two separable pieces being the penetrating non coring cannula adapter assembly  37  and the application element assembly  51 , the application element cannula adapter end  54  and the penetrating non coring cannula adapter aperture  50  are matingly engagable in a substantially fluid type manner. This is to allow the application element assembly  51  to be interchangeable. 
   The selected fluid  64  that is used in the fluid dispenser assembly  20  comprises a wide range of different selected fluids  64  wide range of applications as desired by the user. The range of selected fluids can have a wide range in fluid properties, such as density, viscosity, and the like ranging from gases to light liquids, such as water, to heavy gels. Some common examples for the selected fluid  64  would be but not limited to epoxies, glue, various chemical applications, solvents, cosmetically related applications such as lip lacquer, rouge, face makeup, nail polish, nail polish remover, cuticle remover, hair coloring, and shave cream. Other general use fluids for the selected fluid  64  which include ink, paint, stain, correction fluid, shoe polish, foods, sauces, pastry, or medical uses such as, medications, drugs and the like. The desired location of where to apply the selected fluid  64  by the user can include but is not limited to various surfaces, cavities, remote areas, volumes, and the like. 
   Due to the wide range of selected fluids  64  that can be used it is desirable to have a number of options available for the application element  62  to accommodate not only a number of selected fluids  64  but also the variability in the desired locations of where to apply the selected fluid  64 . Thus, in referring to  FIG. 14  shown is an application element in the form of a nozzle element  90  that would be useful for applying for instance a glue or epoxy to a cavity. Additionally, in referring to  FIG. 15  shown is an application element in the form of an open cell foam element  92  that would be useful for applying for instance a paint to a small surface area. 
   Moving to  FIGS. 9 and 10  shown is a cross sectional view of a reservoir assembly for snap bellows  66  that shows the snap bellows resilient body portion in an extended position state  78  in  FIG. 9  and the reservoir assembly for snap bellows  66  that shows the snap bellows resilient body portion in a retracted position state  80  in  FIG. 10 . The reservoir assembly for snap bellows  66  shown in  FIGS. 9 and 10  is similar to the previously described reservoir assembly  22 , wherein a snap bellows resilient body portion  68  replaces the resilient body portion  24  as described in  FIG. 3  in the fluid dispenser assembly  20 . The reservoir assembly for snap bellows  66  that is able to contain the selected fluid includes a snap bellows resilient body portion  68  having a snap billows resilient body portion first end  69  and a snap bellows resilient body portion second end  71 . Also included is the first end-sealing cap  28  and the second end sealing cap assembly  33  of which the second end-sealing cap  30  is shown. The snap bellows resilient body portion  68 , the first end sealing cap  28 , and the second end sealing cap assembly  33  all act in conjunction to define a snap bellows reservoir interior  67 . The snap bellows resilient body portion  68  has bellows that are defined by a plurality of angular segments each having a pair of sides that are of unequal length with a longer side being the snap bellows long side  70  and a shorter side being the snap those bellows short side  72  as shown in the extended position state  78  in  FIG. 9 . The plurality of angular segments each having a pair of sides that are of unequal length is further defined by the angular differences that reside within a single pair of angular segments, as shown in  FIG. 9  by a large snap bellows angle  74  being adjacent to the snap bellows long side  70  and a small snap bellows angle  76  being adjacent to the snap bellows short side  72 . The bellows of the snap bellows resilient body portion  68  are oriented to retract in such a manner that the snap bellows short side  72  of each pair is folded back under the snap bellows long side  70  as shown in  FIG. 10 , with this resulting in the snap bellows resilient body portion  68  retracting between the snap bellows resilient body portion first end  69  and the snap bellows resilient body portion second end  71 . 
   What this results in is that the snap bellows resilient body portion  68  maintains its last selected retracted or extended position, which in turn creates a selectable snap bellows reservoir interior volume  67 . Each one of the angular segments comprising the snap bellows long side  70  and the snap bellows short side  72  is deformed slightly as the snap bellows short side  72  is forced under the snap bellows long side  70  and as the snap bellows short side  72  passes center, it is substantially firmly held in place. The retracted position state  80  of the snap bellows resilient body portion  68  as shown in  FIG. 10  will maintain the retracted position state  80  until the snap bellows resilient body portion  68  is manually forced into an extended position state  78  as shown in  FIG. 9  which will also be maintained until the snap bellows resilient body portion  68  is manually forced into the retracted position state  80 . The ability of the reservoir assembly for snap bellows  66  to maintain the extended or retracted position state can have several benefits, such as a volumetrically metered control of the volume of the selected fluid  64  that is either dispensed or filled into the snap bellows reservoir interior  67 . 
   Additionally, when the reservoir assembly for snap bellows  66  is normally used by the user placing the reservoir assembly for snap bellows  66  into the retracted position state, because the snap bellows resilient body portion  68  maintains the retracted position state thus maintaining a reduced snap bellows reservoir interior  67  interior volume, reduces the need for venting of the snap bellows reservoir interior  67  interior volume to facilitate the selected fluid  64  to flow to the application element  62 . In addition, the maintaining of the retracted position state for the reservoir assembly for snap bellows  66  reduces the tendency of the reservoir assembly for snap bellows  66  to return to the extended position state thus acting to help prevent the draw of excessive atmospheric air into the snap bellows reservoir interior  67  which can cause the selected fluid  64  to prematurely dry out or to entrain atmospheric air bubbles in the selected fluid  64  causing difficulties in applying the selected fluid  64  from the fluid dispenser assembly  20  through the application element  62  to the desired location by the user. 
   The materials of construction for the snap bellows resilient body portion  68  are preferably a resilient synthetic plastic, however, the resilient synthetic plastic could be constructed of materials selected from a group consisting essentially of polyethylene, polypropylene, or polyurethane materials all of which would be preferably compatible with the selected fluid. It may also be desirable for the snap bellows resilient body portion  68  to be constructed of a translucent or clear material to allow the selected fluid that is contained in the snap bellows reservoir assembly  66  interior volume  67  to be viewed by the user of the fluid dispenser assembly  20 , thus allowing the user to ascertain both the quantity of selected fluid in the interior volume  67  and the color of the selected fluid in the interior volume  67 . 
   Further moving to  FIGS. 11 ,  12 , and  13  shown is a perspective view of application element cannula discharge end  56  with a valve  102  shown in a normally urged to close state in  FIG. 11 , with  FIG. 12  showing the valve  102  in a cross section view in the normally urged to close state, and  FIG. 13  showing the valve  102  in a cross section view in a yielded to open state. The valve  102  is positioned to be in fluid communication between the penetrating non-coring cannula lumen  44  and the application element  62 , being adjacent to the application element cannula discharge end  56 . The valve  102  is normally urged to a closed state as shown in  FIGS. 11 and 12 , and is subsequently yieldable to an open state as shown in  FIG. 13  when the valve  102  is exposed to the selected fluid flow from the penetrating non coring cannula lumen  44 , this results in the selected fluid in the penetrating non coring cannula lumen  44  then flowing to the application element  62  when the valve  102  is in the open state as shown in  FIG. 13 . 
   When the selected fluid ceases or terminates flow from the penetrating non coring cannula lumen  44  to the valve  102 , the valve  102  is urged to return to the closed state as shown in  FIGS. 11 and 12  with the result that seepage or leakage of the selected fluid from the penetrating non coring cannula lumen  44  onto the application element  62  is substantially reduced. The valve  102  is constructed of a first resilient arcuate wall portion  82  and a second resilient arcuate wall portion  84  that are positioned to be diametrically opposed to one another to define a common discharge passage  104  that terminates in a valve closure  86  therebetween for the selected fluid. The first resilient arcuate wall portion  82  and the second resilient arcuate wall portion  84  are normally urged in a radial inward direction against one another to close the valve  102 , thus placing the valve  102  in a closed state as shown in  FIGS. 11 and 12 . When the valve  102  is exposed to the selected fluid flow from the penetrating non coring cannula lumen  44  the first resilient arcuate wall portion  82  and the second resilient arcuate wall portion  84  are normally urged in a radial outward direction to separate thus to define a common discharge passage  104 , and placing the valve  102  in an open state as shown in  FIG. 13  allowing the selected fluid to flow from the penetrating non coring cannula lumen  44  to the application element  62 . 
   The materials of construction for the valve  102  are preferably comprised of a silicone rubber or other rubber or rubber like material that has a varying resilience depending upon the viscosity of the selected fluid and is also preferably compatible with the selected fluid. 
   Next in looking at  FIG. 16 , shown is a cross section view of the refill fluid dispenser assembly  21  in use to fill the reservoir assembly  22  from an external selected fluid source  94  with the selected fluid  64  communicating from the external selected fluid source  94  to the reservoir assembly  22 . The reservoir assembly  22  that is able to contain the selected fluid  64  includes a resilient body portion  24  that has a resilient body portion first end  25  and a resilient body portion second end  31 . The reservoir assembly  22  also includes a first end sealing cap  28  and a second end sealing cap assembly  33  that includes a second end sealing cap  30  that acts in conjunction with the resilient body portion  24  to define a reservoir interior  35 . The resilient body portion  24  has a bellows  26  that is oriented to retract or extend the resilient body portion  24  between the resilient body portion first end  25  and the resilience body portion second end  31  with the result that a variable reservoir interior volume  35  is possible. The bellows  26  is in a bellows retracted position state  29 . The second end sealing cap  30  also includes a penetrable elastomeric member retainer  34 , a penetrable elastomeric member support  32 , and a penetrable elastomeric member  36 . 
   There is also included an applicator support element  88  that is secured between the reservoir assembly  22  and the penetrating non coring cannula adapter refill assembly  49  that is adapted to removably engage either or both the reservoir assembly  22  and the penetrating non coring cannula adapter refill assembly  49 . The applicator support element  88  is intended to provide additional support to the penetrating non coring cannula adapter refill assembly  49  attachment to the reservoir assembly  22  being secured between the reservoir assembly  22  and the penetrating non coring cannula adapter refill assembly  49 , wherein the interface of the penetrating non coring cannula body  38  and the penetrable elastomeric member  36  after the penetrating non coring cannula body  38  has been inserted and penetrated through the penetrable elastomeric member  36  provides an inadequately rigid attachment between the penetrating non coring cannula adapter refill assembly  49  and the reservoir assembly  22 . The form of the applicator support element  88  can be either internal or external to the reservoir assembly  22 .  FIG. 16  shows the applicator support element  88  to be internally mounted, thus residing in the reservoir interior  35 , with the applicator support element  88  having a slidable or removable engagement with the penetrating non coring cannula body  38 , thus providing extra support rigidity for the attachment between the reservoir assembly  22  and the penetrating non coring cannula adapter refill assembly  49 . However, the applicator support element  88  could just as well be mounted on the exterior of the reservoir assembly  22  being secured between the second end sealing cap assembly  33  and the penetrating non coring cannula adapter refill assembly  49 . Wherein more particularly the applicator support element  88  would be removably engagable on either or both the second end the sealing cap assembly  33  and the penetrating non coring cannula adapter refill assembly  49 . 
   The materials of construction for the resilient body portion  24  are preferably a resilient synthetic plastic, however, the resilient synthetic plastic could be constructed of materials selected from a group consisting essentially of polyethylene, polypropylene, or polyurethane materials all of which would be preferably compatible with the selected fluid  64 . It may also be desirable for the resilient body portion  24  to be constructed of a translucent or clear material to allow the selected fluid  64  that is contained in the reservoir assembly  22  interior volume  35  to be viewed by the user of the refill fluid dispenser assembly  21 , thus allowing the user to ascertain both the quantity of selected fluid in the interior volume  35  and the color of the selected fluid in the interior volume  35 . The materials of construction for the first end sealing cap  28 , the second end sealing cap  30 , penetrable elastomeric member support  32 , applicator support element  88 , and penetrable elastomeric member retainer  34  can be constructed of any material that is preferably compatible with the selected fluid  64 . The materials of construction for the penetrable elastomeric member  36  should be in addition to being preferably compatible with the selected fluid  64  have a resiliency to allow for a substantially fluid tight seal between the penetrable elastomeric member  36  and the penetrating non coring cannula body  38  when the penetrating non coring cannula body  38  penetrating non coring cannula insertion end  43  is inserted and penetrated through the penetrable elastomeric member  36  and protrudes into the reservoir interior  35 . In addition, the materials of construction for the penetrable elastomeric member  36  should allow for a substantially fluid tight seal when the penetrating non-coring cannula insertion end  43  is removed from the penetrable elastomeric member  36 . 
   The refill fluid dispenser assembly  21  also includes the penetrating non coring cannula adapter refill assembly  49  that is comprised of a penetrating non coring cannula insertion end  43  and an oppositely positioned penetrating non coring cannula adapter  53  for attachment to an external selected fluid source  94 . The penetrating non-coring cannula adapter refill assembly  49  includes a penetrating non-coring cannula assembly  39 . The penetrating non-coring cannula assembly  39  comprises a penetrating non-coring cannula body  38  with a penetrating non-coring cannula lumen  44 , and a penetrating non-coring cannula insertion end  43 . The penetrating non coring cannula insertion end  43  is adapted to insert and penetrate through the penetrable elastomeric member  36  and protrude into the reservoir interior  35  to enable fluid communication between the reservoir interior  35  and the non coring cannula lumen  44 . The flowrate of the selected fluid  64  may be controlled by the non coring cannula lumen  44  that can be sized by a flow restriction through either controlling the inside diameter of the non coring cannula lumen  44  or by the use of an orifice restriction positioned adjacent to and in fluid communication with the non coring cannula lumen  44  using generally known flow restriction and orifice fluid flow calculations depending upon the selected fluid  64  properties such as density, viscosity, and the like. The side of the penetrating non coring cannula body  38  opposite of the penetrating non coring cannula insertion end  43  has a penetrating non coring cannula adapter body  46  that terminates in a penetrating non coring cannula adapter  53 . The penetrating non-coring cannula adapter  53  is adapted for attachment to the external selected fluid source  94 . The penetrating non-coring cannula adapter  53  has a substantially fluid tight matingly engagable attachment to the external selected fluid source  94 . The external selected fluid source  94  can be any type of external reservoir for containing the selected fluid that will usually be of a higher volumetric selected fluid  64  capacity that the reservoir assembly  22 . A penetrating non coring cannula adapter aperture  50  is in fluid communication with the penetrating non coring cannula lumen  44 , additionally the penetrating non coring cannula adapter aperture  50  is in fluid communication with the external selected fluid source  94 , allowing selected fluid communication from the external selected fluid source  94  to the penetrating non coring cannula adapter aperture  50  onward to the penetrating non coring cannula lumen  44  and finally to the interior volume  35  of the reservoir assembly  22 . 
   The materials of construction for the penetrating non coring cannula body  38 , the penetrating non coring cannula adapter body  46 , the penetrating non coring cannula adapter  53 , and external selected fluid source  94  can be constructed of any material that is preferably compatible with the selected fluid  64 . 
   In use the reservoir assembly  22  may be supplied to the user without the selected fluid  64 , in other words the reservoir interior  35  would be emptied being devoid of the selected fluid  64 . Alternatively, the reservoir assembly  22  may have the reservoir interior volume  35  sized to be filled or refilled with the selected fluid  64 . In using the refillable fluid dispenser assembly  21  the user would first grasp the reservoir assembly  22  between the first end sealing cap  28  and the second end sealing cap and compress the resilient body portion  24  bellows  26  into a retracted position state between the resilient body portion first end  25  and the resilient body portion second end  31  with the result in a reduced reservoir interior volume  35  as shown in  FIG. 16 . Next, or secondly, the user inserts the penetrating non coring cannula adapter refill assembly  49  into the penetrable elastomeric member  36  and then attaches the external selected fluid source  94  and then engaging the applicator support element  88  if needed. 
   Further or thirdly, the user would manually place the resilient body portion  24  bellows  26  into the extended position state between the resilient body portion first end  25  and the resilient body portion second end  31  with the result in an increased reservoir interior volume  35 . This will result in accomplishing the subsequent filling or refilling of the fluid dispenser assembly  21  for multiple uses of the fluid dispenser assembly  20 . This may be with a single insertion of the penetrating non coring cannula adapter refill assembly  49  into the penetrable elastomeric member  36  or with multiple insertions and removals&#39; of the penetrating non coring cannula adapter refill assembly  49  into and out of the penetrable elastomeric member  36 , that would allow multiple refills of the reservoir assembly  22  reservoir interior volume  35 . The resealing ability of the elastomeric member  36  helps to keep the selected fluid  64  from drying out or hardening in the reservoir assembly  22 , and also helps in preventing spills and leakage of the selected fluid  64  from the reservoir assembly  22 . The refill fluid dispenser assembly  21  may be set up for multiple refills with a cleanable penetrating non coring cannula adapter refill assembly  49  or the use of multiple penetrating non coring cannula adapter refill assemblies  49  that are each individually disposable. 
   METHOD OF USE 
   Referring back to  FIGS. 8 ,  9 , and  10  showing the fluid dispenser assembly  20  in use, the following method of using is given for the fluid dispenser assembly  20  for manually applying a selected fluid  64  to a desired location comprising various steps for a typical use of the fluid dispenser assembly  20 . Firstly, providing a fluid dispenser assembly  20  that includes a reservoir assembly  66  containing the selected fluid  64 , the reservoir assembly  66  also includes a resilient body portion  68  having a first end  69  and a second end  71 , a first end sealing cap  28 , and a second end sealing cap assembly  33  to define a reservoir interior  67 . The body  68  having bellows that are defined by a plurality of angular segments each having a pair of sides that are of unequal length with a longer side  70  and a shorter side  72 . The bellows are oriented to retract with the shorter side  72  of each pair being folded back under the longer side  70  resulting in the body  68  retracting between the first end  69  and the second end  71  with the body  68  maintaining its last selected retracted or extended position. The second end sealing cap assembly  33  includes a penetrable elastomeric member  36  and an applicator assembly  47  having a proximal end  98  and a distal end  100 . The proximal end  98  includes a non coring cannula  38  with a lumen  44  having an insertion end  43  that is adapted to insert and penetrate through the elastomeric member  36  and protrude into the reservoir interior  67  enabling fluid communication between the reservoir interior  67  and the lumen  44 . The distal end  100  includes an application element  62  that is in fluid communication with the lumen  44 . 
   Secondly, positioning the application element  62  at the desired location of where to apply the selected fluid  64  by the user can include but is not limited to various surfaces, cavities, remote areas, volumes, and the like. Thirdly, manually retracting the reservoir body  68  a sufficient amount to initiate the selected fluid  64  to communicate from the reservoir interior  67  to the lumen  44  and onward to the application element  62 . This is accomplished by manually by placing the user&#39;s thumb and forefinger on the first end sealing cap  28 , and a second end sealing cap  30  respectively, and gently squeezing together the user&#39;s thumb and forefinger thus retracting the body  68  causing the selected fluid  64  to flow from the reservoir interior  67  and into the lumen  44  with the selected fluid  64  which is then deposited onto the application element  62  allowing application of the selected fluid  64  to the desired location. Fourth, the user applying the selected fluid  64  to the desired location by use of the application element  62 . Fifth, retracting the reservoir body  68  further to a retracted position by a single angular segment pair causing the shorter side  72  of the pair being folded back under the longer side  70 , with the body  68  maintaining the retracted position thus continuing the selected fluid  64  communication from the reservoir interior  67  to the lumen  44  and onward to the application element  62 . The user would then sequentially repeat steps four and five until the selected fluid  64  has been completely applied to the desired location.
