CROSS REFERENCE TO A RELATED APPLICATION 
       [0001]    This is a utility patent application derived from, relating to and incorporating by reference U.S. Patent Application Ser. No. 61/990,599 entitled Container Throat Dispensing Adapter and Method, filed on May 8, 2014 for which priority is claimed. 
     
    
     BACKGROUND 
       [0002]    In the automotive industry, servicing driveline fluids has become more complex. With a multitude of different blends, viscosities and retail container packaging, pouring required lubrication fluids into a funnel to reach a service fill port is no longer a convenient or simple task. Most service applications do not involve a dipstick or similar means of checking fluid levels that require service. Most service fill ports are accessed at locations underneath the vehicle and are difficult to reach or obstructed by body or vehicle frame components. Typical transmissions and axle differentials can only be serviced with some type of fluid transfer pumping method to replenish the fluid since they cannot be filled by gravity flow. 
         [0003]    Present alternative methods have drawbacks. For example, some retail package squeeze type fluid bottles have a tapered spout cap and one must invert the container to remove it contents by grasping and squeezing the bottle and or attaching a length of flexible hose to reach inaccessible service port. This method creates numerous problems. (1) The flexible hose usually has a poor fit on the smooth tapered container spout and slides off. (2) The length of flexible hose may have a smaller inside diameter than the tapered container spout precluding a positive connection to the spout. With the smaller diameter length of hose, fluid transfer is restricted and requires more internal bottle pressure by squeezing and/or by a clamping device on such container. (3) With higher internal bottle pressure required for transferring such fluid, the poor fit of a flexible hose installed on a tapered spout leads to a very high percentage of the hose disconnecting from the spout end. (4) When the hose connection fails and the fluid being transferred is a lubricant, not only may leak that needs attention may result, but also the spout end becomes lubricated, which complicates the retaining of the flexible hose connection to the spout end. (5) The tapered spout cap design, does not allow use of some type of a hose retaining/clamping device. (6) When the service fill port is located at a higher location and obstructed, for example, by a structural frame member, a longer flexible hose is required to reach the service fill port. This compounds the existing problems of fluid transfer. Further, because the container still needs to be inverted to remove all contents, which usually requires even a longer flexible hose. This compounds fluid transfer resistance. (7) Most squeeze type lubricant fluid bottles in the retail market have a foil gasket seal of some type under the threaded spout cap. This gasket prevents fluid content leakage until used by the end consumer and must be removed prior to usage. If the gasket seal is not completely removed from the bottle throat top, the spout cap will not create a liquid impervious seal and leakage may then occur when increasing internal bottle pressure to pump fluid contents. Even with all of the gasket seal removed, bottle manufacturing tolerances are inconsistent and a poor fit to a bottle throat by a spout cap may result in leakage. (8) When such a task is done, the length of flexible hose needs to be cleaned so if used again with a different type of fluid, contamination will not occur. 
         [0004]    One solution enabling use of an original factory package (container/vessel) is to provide an additional pump mechanism that threads onto the bottle. This method creates numerous problems also: (1) It may require a hand pump that threads onto the container with a long length of flexible hose to reach the service fill port. (2) The pump mechanism needs to be designed exclusively for the bottle thread pitch and depth. (3) Holding the container/bottle with one hand and operating a hand pump with the other hand may cause the flexible hose to become loose and not retained in a service port and possibly disconnect thereby creating leakage. (4) Most pumps are poorly made and leak around the pump seal handle after a few usages. (5) After usage, cleanup of such pump assemblies are very difficult and time consuming. Cleaning solvents to completely remove all fluid contaminates for the next usage may be required. Cleaning solvents may be harsh and attack the pump components and increase the rate of pump seal and hose failure. (6) Upon usage over time, the flexible hose may become stiff or rigid due to being subjected to chemicals, which makes use and cleaning difficult. (7) When not in use, storage of such pump and hose assemblies requires some type of residue leakage containment. 
         [0005]    Additional alternate methods of fluid replacement include transfer of fluid lubricant into a separate container or pumping device to reach a service port. This coincides with recent changes of lubrication fluids and packaging. Most factory retail packaging has changed bottle design of throat size and thread pitch. This requires an additional external container to be filled first with the original fluid contents, and then dispensed by some type of pumping method. 
         [0006]    These alternative methods have created numerous problems also: Method (ONE) The use of a hand suction pump or a push pull pump with multiple flexible hoses. (1) Requires the hose of the suction cylinder to be inserted into fluid container to pull fluid into the suction cylinder, and then pump into the service port. This type of method creates residue on the external part of the hose which, in turn creates a mess. (2) Requires use of both hands to operate, leaving the hose loose in the service port for possible leakage. (3) Most hand suction pumps are difficult to use with higher viscosity/thicker fluids. (4) Most hand suction pumps leak after a few usages. (5) Usage over time may cause, the flexible hose to become stiff or rigid due to being subjected to chemicals. (6) When operating a push/pull pump, one end of a hose is inserted into the fluid container and the other end is inserted to the service port. Both hose ends are loose in their perspective ports. The most common failure is that the fluid supply bottle is not being secured thereby tipping the fluid container due to hose movement while pumping. (7) Once service of fluid is completed, the amount of fluid residue in the hoses leaks until transferred to the next container or cleaned for storage. 
         [0007]    Alternate Method (TWO) In-line hand powered, electric or pneumatically powered rotary pumps require use of both hands to operate the pump with two long flexible hoses, one on each end. The same problems as alternate method (ONE &amp; TWO) are observed. 
         [0008]    Alternate Method (THREE) Air pressurized container to push fluid through a flexible hose to service port, (1) Requires service fluid to be transferred first to a vessel/container. Then the container is pressurized by means of a hand air pump or compressor. (2) A length of flexible hose from pressurized container to reach the service port location is required. (3) Some type of shut off valve when servicing is required to stop fluid dispensing. (4) Man of the same problems as observed for methods ONE and TWO are observed. (5) Cleanup is more complicated and time consuming. (6) System is not a cost effective for the end user. 
       BRIEF SUMMARY OF THE INVENTION 
       [0009]    It is therefore an objective of the present invention to provide an improved method for removal of fluid from the original manufactured retail package squeeze type fluid bottle where pressure is required to transfer such fluid. With the container throat dispensing adapter disclosed and installed on an original retail bottle, the bottle will become the fluid container and a pump mechanism to dispense such fluid. 
         [0010]    In accordance with a first aspect of the invention, the tapered adapter or plug can be inserted into a bottle throat opening against the interior wall thereof. The tapered adapter will create a liquid impervious seal between the internal part of the bottle throat interior wall opening and a tapered adapter. Then a plastic extension tube assembly may insert through a center bore of the adapter. Upon continuing to push the extension tube assembly through the tapered adapter, contact is made with the inside base of the bottle. This will allow all the fluid in the bottle to be removed through the extension tube assembly by creating internal bottle pressure by means of grasping and repeatedly squeezing the bottle to pump the fluid outward from the bottle to the service port location. 
         [0011]    According to a second aspect of the invention, a threaded cap adapter may include multiple diameter threads which consist of two or more separate sizes to enable engagement with multiple bottle throat sizes. The threaded adapter replaces a bottle cap and screws onto the bottle throat opening where the original threaded twist off cap was located. Also a cylindrical spout in the threaded cap with a bore receiving a plastic extension tube assembly may be inserted into the bottle to reach the bottle fluid contents. This will allow all the fluid in the bottle to be removed through the extension tube assembly by causing internal bottle pressure by means of grasping and squeezing the bottle to pump the fluid outward and, if necessary, upward to the service port location. 
         [0012]    According to a third aspect of the invention, a threaded cap adapter may employ two or more separate sizes. The smaller cap adapter fits a smaller bottle throat size and the larger cap adapter fits a larger bottle throat size. The adapters screw on to the bottle throat opening where the original threaded twist off cap was located. Both small and large cap style adapters include a cylindrical spout and a throughbore into which the plastic extension tube assembly can be inserted and extend to reach the bottle fluid contents. This will allow all the fluid in the bottle to be removed through the extension tube assembly by creating internal bottle pressure by means of grasping, and repeatedly squeezing the bottle to pump the fluid outward and upward, if necessary, to a service port location. 
         [0013]    According to a fourth aspect of the invention, a threaded cap adapter comprises a large size that fits a larger bottle throat size. The large size cap adapter typically includes a cylindrical spout and a throughbore through which a plastic extension tube assembly inserted to reach the larger size bottle fluid contents. A smaller adapter has internal and external threads with a larger throughbore. This smaller threaded adapter can be threaded into the larger cap adapter and reduces the adapter cap assembly to fit the smaller bottle throat size. These adapters screw on to the threaded bottle throat opening where the original threaded twist off cap was located. This will allow all the fluid in the bottle to be removed through the extension tube assembly by creating internal bottle pressure by means of grasping and squeezing the bottle to pump the fluid upward to the service port location. 
         [0014]    According to a still further aspect of the invention, the adapters enable repositioning the pick-up extension tube in the adapter cap throughbore and dispensing of fluid with the bottle angled or inverted to reach a lower service port location. This allows dispensing of some or all the fluid from the bottle into an obstructed reservoir service fill port without the use of a funnel. 
         [0015]    According to yet another aspect of the invention, a step-by-step process and method enables use of a retail package squeeze type fluid bottle by modifying the original bottle cap spout to accept an internal extension tube assembly and to cooperate with multiple size bottle openings. 
         [0016]    These and other objects, aspects, advantages and features of the invention and the embodiments are set forth in the following detailed description.

       DETAILED DESCRIPTION 
       [0053]    A universal, tapered, multiple section, rubber or elastic adapter or plug with a throughbore is designed to fit multiple types of industry standard sizes of squeeze type fluid bottle dimensions and throat openings available in the retail market. Since an embodiment of the stepped, tapered, rubber adapter may be inserted into the inside of a bottle opening or throat interior wall, it does not rely upon the external bottle threads to make a liquid impervious seal similar to a threaded screw on cap. Referring to  FIGS. 1-3 , the stepped tapered adapter is typically comprised of medium softness and elastic urethane. This allows a snug, positive fit of the adapter or plug to conform or mold itself to the internal wall at the bottle throat opening. The tapered adapter comprising a pliable material provides a liquid impervious seal obviating manufacturing distortion that can be a factor in a threaded cap or bottle opening. When a plastic extension tube is inserted through the bore in the plug or adapter, the adapter may be expanded or radially outwardly compressed with a sealing force on the throat interior or wall of the bottle opening. Continuing, to insert the plastic extension tube through to make contact with the base of the fluid container, allows vertical dispensing of fluid, such as lubricant, by using the original retail bottle as a pumping device. Grasping and squeezing the flexible material bottle creates a positive pressure inside the bottle forcing fluid out through the extension tube. Upon releasing pressure or squeezing of the bottle, the pliable plastic bottle container will assume its original shape and allow air to enter the bottle through the extension tube to replace the fluid contents forced out thereby enabling a further cycle of compressing the container for continued dispensing of lubricant or fluid. Elbow tube adapters can be attached to the discharge end of the extension tube to access service fill ports in a vertical or a horizontal position. 
         [0054]      FIG. 5  and  FIG. 6  depict different sizes of common squeeze type fluid containers or lubrication bottles  36 ,  38  that have a smaller or a large throat diameter or opening and other different physical designs.  FIG. 5  depicts a tapered step adapter or plug  12 , used in the position of a larger diameter section  48 , shown in  FIG. 4  of a two or dual tapered size plug  12  in combination with an extension tube  14  that extends substantially to the inside base  38  of the bottle  36 .  FIG. 6  depicts the tapered step adapter  12 , used in the position of the smaller diameter section  52  of the two tapered sections  48 ,  52  of  FIG. 4  along with an extension tube  14  extended the inside to the base of the bottle  36  and incorporating an elbow tube adapter  20  at the discharge end of tube  20 . 
         [0055]      FIG. 9  illustrates a machinery component such as an automatic transmission and reservoir or pan  40  that requires servicing or filling from a bottom service port location. Servicing requires vertically filling the transmission reservoir  40  through a bottom port until the fluid level reaches the top of a fill port and leaks out to provide the correct fluid level. Typically there is no indicator or reference for this common application such as a dipstick for checking the compliance with proper recommended fluid level. Using the present invention enables filling the reservoir  40  and detection of complete filling. Using the stepped tapered rubber plug or stopper or adapter  12  inserted into the throat of bottle  38  and then inserting the ridged plastic extension tube  14  through the throughbore  58  (in  FIG. 1 ) to contact at or near the base of the bottle  38  and combining this assembly with the depicted arcuate elbow adapter  20  may then be used for filling reservoir or pan  40  to the proper level. The fluid is disbursed by means of creating internal bottle pressure by grasping and squeezing the bottle  38  and then by releasing the squeeze bottle  38 . A further volume of fluid may then be dispensed from the bottle  38  by squeezing the bottle  38  to compress the fluid with air drawn back through the extension tube  40  and discharge elbow  20  assembly. This comprises as a pumping method to dispense fluid. 
         [0056]      FIG. 7  depicts another method to reach a service port that is in a lower location with limited access. A bottle  36  of a different design and a smaller throat or opening size is combined with a shorter plastic extension tube  16  incorporating a different elbow discharge adapter tube  30 . This allows a more calibrated and controlled amount of fluid to be dispensed and is useful when a straight funnel will not access the service fill port. 
         [0057]    The stepped tapered rubber adapter  12  is typically injection-molded or cast urethane with medium shore hardness. An example is depicted in  FIG. 1 ,  FIG. 2  and  FIG. 4 . The stepped tapered adapter typically consists of multiple frusto-conical steps or tapered sections  48 ,  52 . A cylindrical throughbore  58  plug of  12  has a diameter slightly less than the outside diameter of the extension tube  14 . This arrangement creates a liquid impervious seal around the extension tube  14  outer wall and retains the extension tube  14  position in throughbore  58 . When such an extension tube  14  is inserted, the stepped tapered adapter  12  expands slightly larger in overall diameter for more positive sealing force on internal wall at the throat opening of a bottle. The bottom flat surface  56  of the tapered adapter  12  and lesser radius surface  54  of lower end of plug  12  facilitates inserting the tapered adapter  12  into the interior of the smaller bottle throat openings. The adapter  12  thus has slight tapered conical surfaces smaller at the very bottom of plug  12 , with a cylindrical positive expanding taper upward towards the top of the tapered section. This provides a positive sealing force for different bottle throat sizes and compensates for opening manufacturing inconsistencies of bottle openings. Plug section  48  also includes a conical surface diameter section  50  at the bottom, with a positive increasing taper upward towards atop section  44 . The slight cylindrical positive expanding taper upward thereby provides a positive sealing force upon insertion into larger bottle size openings and compensates for manufacturing inconsistencies conical lid section  44  and provides a hand hold for installing and removing the tapered adapter or plug  12 . 
         [0058]      FIG. 4  illustration is a sectional view of a tapered adapter, plug or stopper  12  with extension tube  14 .  FIG. 8  shows the different diameters and configurations of extension tubes and adapters to access different types of service port designs. The tubes are typically made of polyethylene or polypropylene extruded tubing. Bottle extension tubes  14  and  16  are larger diameter to permit flow of high viscosity fluids, such as differential gear oil. Discharge tips or tubes  20 ,  22 ,  24 , and  30  have an expanded connection end that fits over the extension tubes  14  and  16 . This maintains the larger inside diameter for less restrictive flow of fluid. 
         [0059]    Adapter  22  is convoluted or flexible at one end to provide a range of multiple angle requirements. Adapters  26  and  32  have a diameter size which enables placement into the throughbore  58  inside diameter of the larger tubes  14 ,  16 ,  20 ,  22 ,  24   30  with a slight interference fit to create a positive seal between the inner and outer walls. Adapter  18  is straight and has the same outer diameter as adapter  32 . Tube  18  is used to fit inside the larger tubes  14 ,  16 ,  20 ,  22 ,  24 ,  30  as a bushing for adapters  28  and  34 . Also adapters  28  and  34  fit inside adapters  26  and  32 . 
         [0060]      FIG. 10  depicts an embodiment of an assembled perspective design of a threaded adapter cap for a squeeze type fluid bottle. Threaded cap  72  incorporates two different sizes of internal thread sizes.  FIG. 11 ,  FIG. 12  and  FIG. 13  depict sectional views. A spout tip  74  incorporates a smaller inside diameter cylindrical throughbore  80  which accommodates plastic extension tube  14  with an interference fit to retain the extension tube  14  in position. Bore  80  is internally tapered outward from lower end  82  to spout tip  74  to aid insertion of plastic extension tube  14 . This provides a liquid impervious seal to the bore of tubes  74  and  14 . An annular female recess cavity  76  is provided for sealing of a small squeeze type fluid bottle  36  throat top opening. This structure creates a positive sealing force to the bottle top throat when the adapter  72  is threaded on by internal thread  88 .  FIG. 14  shows cap adapter  72  threaded onto the small squeeze type fluid bottle  36  as an assembly incorporating extension tube  14  extended to the base of the bottle  36  and including an adapter elbow  20 . 
         [0061]      FIG. 12  depicts an annular female recess cavity  78  for seating in a larger squeeze type fluid bottle  38  throat top opening using a threaded cap embodiment of the invention. This arrangement creates a positive sealing force to the bottle top throat when the adapter  72  is threaded on by internal thread  86 . The external surface  88  of the inner cap is slightly tapered at the outer bottom of the internal cap to thereby compress against the larger squeeze type fluid bottle internal throat slightly to aid in sealing in the cavity  78  when the adapter cap is threaded thereon.  FIG. 13  depicts a cap adapter  72  threaded onto the larger squeeze type fluid bottle  38  as an assembly incorporating extension tube  14  extended to the base of the bottle&#39;s fluid. Adapter elbow  30  is attached to outer end of tube H. 
         [0062]      FIG. 14  is a sectional view depicting the placement of a threaded cap adapter  72  embodiment in combination with a tube  14  and an extension elbow  20  affixed to a bottle  36  having a small threaded throat opening. The adapter  72  includes an annular threaded section such as depicted as threaded section  84  in  FIG. 11  which is threaded onto the top of the bottle  38  and more particularly to the threads thereof. The annular recess  76  seals the adapter or cap  72  to the bottle opening. In contrast,  FIG. 13  depicts the cap construction of  FIG. 11  wherein the threads  86  are mated with a larger opening of bottle  38 . Again, an annular recess  78  seals the cap into position in the bottle opening of the embodiment as depicted in  FIG. 13 . 
         [0063]      FIG. 15  is another assembled perspective design embodiment of an adapter cap assembly for a smaller squeeze type fluid bottle  36 . A threaded cap  102  incorporates internal thread size for smaller squeeze type fluid bottle  36 .  FIG. 16  and  FIG. 17 , show the sectional views. A spout tip  104  incorporating a smaller inside diameter cylindrical throughbore accommodates plastic extension tube  14  with an interference fit to retain the extension tube  14  in position. Tapered outward sections  106 ,  108  at each end of tip  104  aid in inserting plastic extension tube  14 . This provides a liquid impervious seal to the bore of tip  104  and plastic extension tube  14 . A female recess cavity  110  for the small squeeze type fluid bottle throat top opening  36  creates a seat for a positive sealing force to the bottle top throat when the adapter  102  is threaded on by internal thread  112 .  FIG. 21  shows a cap adapter  102  threaded onto the small squeeze type fluid bottle  36  as an assembly incorporating extension tube  14  extended to the base of the bottle fluid. An adapter elbow  20  is affixed to the outer end of tube  14 . 
         [0064]      FIG. 18  is a perspective view of an assembled embodiment of a adapter cap assembly for a larger squeeze type fluid bottle  38 .
