Abstract:
An improved pressurizing sprayer removably attaches to the threaded neck of a container and includes a main body having a handle portion and a head portion. The handle includes a top portion with an exposed trigger and an inside portion in which a hand operated squeeze bulb pump is fitted. The head portion houses a pinch valve which is interconnected in-between a spray nozzle and a fluid conduit. Manually squeezing the pump delivers air into the container. Manually pressing the trigger continuously or intermittently opens the pinch valve allowing the fluid to flow through the conduit and out of the spray nozzle in the form of a pre selected spray pattern. Relatively few pump strokes are required to pressurize the sprayer. The tasks of aiming, spraying, and pressurizing can be completed simultaneously and with the use of only one hand.

This patent application also claims priority from provisional patent application No. 60/429,096 having a filing date of Nov. 26, 2002 
     
    
     FIELD OF THE INVENTION  
       [0002]     This invention relates to pressurizing devices for fluid containers, and particularly to a pressurizing dispenser device adapted for removable or permanent attachment to a fluid container.  
       DISCUSSION OF THE RELATED ART  
       [0003]     Many beverages, and particularly soft drinks, are impregnated with carbon dioxide gas in order to provide a refreshing effervescence which has a pleasant appeal when consuming the beverage. Often carbonated beverages are sold in two or three liter beverage containers in order to reduce the cost per ounce to the consumer. Many people find these larger size beverage containers to be more economical and convenient compared to cans because they can be recapped and stored if the beverage is not entirely consumed after the bottle is initially opened.  
         [0004]     Notwithstanding, larger size carbonated beverage containers do present some problems to the user. In particular, it is well known that the carbonation has a tendency to escape into the atmosphere if the beverage is not contained under pressure. Because a closed beverage bottle, when half full, contains a large sealed open air space, the gas in the beverage is able to escape into this open space even when the cap is tightly secured to the bottle. Once the cap is removed, the carbonation gas in this space releases into the atmosphere. When carbon dioxide gas escapes from a carbonated beverage, the desirable sparkling effervescence is lost and cannot be replaced. Once this happens, the carbonated beverage become flat, leaving an undesirable taste with no refreshing appeal to the consumer. In this instance, the carbonated beverage will most likely be discarded or thrown away, thereby effectively increasing the cost per used ounce to the consumer. This certainly defeats the primary purpose of purchasing carbonated beverages in larger containers, which is to provide a greater volume of product to the consumer at a lower cost per ounce.  
         [0005]     Additionally, it would be desirable to pressurize containers containing other types of fluid without requiring the use of toxic and dangerous (e.g., flammable) propellants. For example, many types of cleaning solutions are sold in a bottle having a trigger-pump type sprayer. To apply the fluid using a trigger-pump type sprayer, the user typically aims the bottle at the surface to be cleaned and pumps several blasts of cleaning solution onto the dirty surface. However, the area that is actually wetted by the cleaning solution is limited only to those areas wetted by the blasts. Other areas remain substantially dry until a cloth or sponge is used to spread the solution around. The result is that the areas receiving the initial blasts are thoroughly cleaned, but other areas may not receive enough of the cleaning solution to be effectively cleaned. It would be desirable to provide a continuous stream of a cleaning fluid so that all areas of a dirty surface are wetted by the solution without requiring the use of toxic and dangerous (e.g., flammable) propellants.  
         [0006]     The same holds true for other types of fluids, such as cooking oils, paints, etc.  
         [0007]     Pumping devices have been proposed for pressurizing the open volume within a carbonated beverage bottle with ambient air. It is also known to combine a closure cap and pressurizing pump for insertion in the neck of a container. U.S. Pat. No. 718,163 to Sherrard (1903) discloses a bottle tap for corked bottles. Air pressure is created in order to facilitate the discharge of the liquid therefrom. U.S. Pat. No. 2,853,207 to Yingst (1954) discloses a device for dispensing liquids. Both Sherrard&#39;s invention and Yingst&#39;s invention function to dispense a liquid from a bottle through a narrow tube which is inserted into the bottle.  
         [0008]     The Ballas U.S. Pat. No. 4,768,665, discloses a hand operated pump which uses a cylinder and piston. The Ballas pump is attachable to a threaded bottle neck. Likewise, U.S. Pat. No. 4,723,670 to Robinson discloses a hand operated pump which attaches to a threaded bottle neck and which uses a cylinder and piston.  
         [0009]     My prior invention, as described in U.S. Pat. No. 5,738,254, addresses many shortcomings of the prior art devices. Notwithstanding, I have conceived of several improvements which eliminate potential problems that may occur in the use of my prior invention. Specifically, the upper end of the squeeze bulb has been specifically structured and configured to provide a multi-sided surface for congruent, keyed engagement within notched cut-outs of the handle to prevent spinning or rotation of the squeeze bulb relative to the handle. Spinning or rotational movement of the squeeze bulb relative to the handle is not desirable because it results in twisting and kinking of the flexible hose which delivers air to the bottle interior. Further, the present invention provides for an improved airtight seal between the ball-shaped member of the valve spout and the valve seat. Accordingly, my present invention provides for improvements to the structure and function of my earlier invention along with new embodiments.  
       SUMMARY OF THE INVENTION  
       [0010]     One embodiment of the present invention is directed to a pressurizing beverage dispenser which removably attaches to the threaded neck of a carbonated beverage container. The dispenser includes a main body which is molded to include an integral handle portion and head portion. A seal mechanism within the head portion provide an air and liquid tight seal between the dispenser device and the discharge opening of the beverage container and include a cap and a valve assembly. The cap is fitted within the head portion and includes interior threads for threaded engagement and attachment to the threaded neck of the beverage container. A central opening through the top of the cap aligns with the discharge opening of the container. The valve assembly includes a pivotal valve spout on the head portion which is moveable between a closed position and an open position. A ball-shaped portion of the valve spout is disposed in mating, sealing engagement with a dish-shaped valve seat. The valve seat is preferably formed of an elastomeric, resilient material such as silicone. An opening in the dish-shaped valve seat aligns with the central opening of the cap and the discharge opening of the beverage container. When the pivotal valve spout is in the closed position, the ball-shaped portion is disposed in blocking, sealing relation to the central opening and discharge opening so that gas and fluid are contained within the beverage container. Movement of the valve spout to the open position serves to rotate the ball-shaped portion relative to the valve seat until a bore formed through the valve spout, defining a fluid passage, aligns with the central opening of the cap, thereby permitting the beverage contents of the container to be poured from the valve spout.  
         [0011]     A pressurizing mechanism is provided for pressurizing the air space of the container after moving the valve spout from the open position to the closed, sealed position. The pressurizing mechanism includes a hand-operated squeeze bulb pump fitted to the handle portion. The squeeze bulb has a central hollow body surrounding a compressible interior air chamber, a first end portion and a second end portion. The first end portion of the squeeze bulb is fitted with a one-directional air intake valve member which is structured and disposed to draw air into the compressible interior chamber of the squeeze bulb as the central hollow body is released from the compressed state and returned to a normally relaxed, full shape. The second end portion of the squeeze bulb is fitted with a one-directional air exhaust valve member which directs air outwardly from the squeeze bulb interior chamber upon compressing the hollow body. A flexible hose connects between the exhaust valve member on the squeeze bulb and the seal mechanism in the head portion, in air flow communication with the interior air space of the beverage container. A mechanism is provided for preventing rotation of the squeeze bulb relative to the handle portion. This prevents the flexible hose from becoming twisted and kinked, which would result in blockage of airflow between the squeeze bulb interior air chamber and the air space within the beverage container interior.  
         [0012]     When the dispenser device of the present invention is threadably fastened to the neck of the beverage container, a charge of air is introduced into the bottle interior by repeatedly squeezing and releasing the hand operated squeeze bulb pump on the handle portion until the interior air space within the container is fully pressurized. The fully pressurized condition will be realized when there is increased resistance in compressing the squeeze bulb pump. Mating engagement of the ball-shaped portion of the valve spout against the valve seat provides an air and liquid tight seal, holding the air pressure and liquid contents within the beverage container. A integral lever extending from the valve spout facilitates ease of movement of the valve between the closed and open positions. When the valve spout is moved to the open position, the charge of pressurized air is released from the bottle. While maintaining the valve spout in the open position, the carbonated beverage within the container may be poured by tilting the container so that the neck is angled downwardly, thus allowing the beverage contents to flow through the passage of the valve spout and into a glass or other drinking vessel.  
         [0013]     Yet another embodiment of the present invention is directed to a portable manual sprayer which may be interconnected and integrally formed to a pump handle that is attachable to a container such as a bottle. Squeezing the pump handle will direct air into the bottle of the sprayer. A trigger may be fixed to one of two points to include the bottom or top portion of the handle. The trigger is connected to a valve. The pump handle has an air tube connected to a bottle of the sprayer. The bottle of the sprayer has an internal tube that is indirectly connected to the valve. Pressing the trigger will open the valve allowing the liquid to flow out of the spray nozzle. Releasing or depressing the trigger will close the valve. A spray volume control is located on the nozzle for selection between mist and stream. The pump handle may include a bulb style air pump that is partially exposed and firmly secured within an ambidextrous handle in a way as to prevent the pump from rotating or spinning thereby avoiding blockage or kinking of the air tube through which air is pumped into the container. One clear advantage of the pump handle is that a user can pump air, spray liquid, hold and maintain manual control of the sprayer all at the same time, with the use of one hand.  
         [0014]     The pump handle can serve a multitude of uses. The pump handle can be interconnected and formed integrally for use with many host devices. These devices would include any device that requires a handle and air to flow into the device. The pump handle can also be interconnected and formed integrally for use with devices which require a handle and air to flow into the device with a trigger fitted to perform a specific task or action such as closing and opening a valve. Other attributes of the pump handle sprayer include an ambidextrous handle, pump and trigger; a precise and directional spray control; relatively few pumps will dispense several ounces of liquid; and a compact and portable but yet fairly simple design. Few parts make it highly reliable and simple to produce and manufacture.  
         [0015]     In addition, the pump handle equipped sprayer may be pressurized in advance of use by pumping the air pump. Then the user only needs to press the trigger of the pressurized sprayer to dispense liquid. This function would be suitable for barber shops and the like, to spray water on hair. The barber would pressurize the sprayer in advance of a customer being seated by pumping the handle a few times. When it is time for use, the barber needs only to hold the sprayer by the handle and depress the trigger for continuous spray or mist without the need to pump repeatedly.  
         [0016]     The pump handle equipped sprayer is well suited for spraying chemicals like cleaning solutions, weed killers, insecticides, etc. With the spray nozzle on one end and the handle on the opposing far end, there is less chance of the hand coming into contact with hazardous chemicals being sprayed. Since the pump sprayer requires relatively low number of pumps, the risk for a repetitive work injury is diminished. Further, the pump handle can be attached to the container to create a disposable unit that cannot be opened without damage to the unit, thereby rendering the unit relatively spill-proof and child-proof. These health and safety features give the pump sprayer a plethora of commercial uses.  
         [0017]     Funnels are often used to refill conventional sprayers. Conventional sprayers are constructed with the handle incorporated into the neck of the bottle; this restricts the diameter of the bottle neck rim to a relatively small size. A bottle neck rim with a larger diameter is desirable because the need for a funnel is eliminated. Since the handle of the pump handle sprayer is located on the outside of the bottle, there are no restrictions to the diameter size of the bottle neck rim.  
         [0018]     The pump handle may also be interconnected and formed integral with other devices including a toy water pistol. The water tank of the water pistol is filled with water, and then squeezing the handle a few times will result in pressurization of the water tank. To spray the water, the trigger is pressed. When the trigger is released the water stops spraying. One novel feature of the water pistol pump handle is that the user may pump, spray, and hold the device with only one hand. Conventional water pistols require the use of both hands, one hand to hold the handle and the second hand to pump a piston pump. A user may hold two water pistols, one in each hand, while pumping and spraying simultaneously.

       DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0075]     The following description is the best mode presently contemplated for carrying out the present invention. This description is made for the purpose of illustrating the general principles of the present invention and is not meant to limit the inventive concepts claimed herein.  
         [0076]     Referring to the several views of the drawings, a pressurizing beverage dispenser device according to one embodiment is shown and is generally indicated as  10 . The device  10  is particularly suited for attachment to a bottle B containing a carbonated beverage, such as a soft drink product. The pressurizing beverage dispenser device  10  removably attaches to the threaded neck N of the carbonated beverage container. The device  10  is particularly suited for use on two-liter and three-liter carbonated beverage containers, of the type shown in  FIGS. 1 and 2  and indicated as B. Beverage containers of this nature are known to include a threaded neck which terminates at a discharge opening surrounded by a top rim. A cap is normally screwed on to the threaded neck to cover the discharge opening in order to preserve the beverage contents therein. When the beverage is consumed, the cap is removed so that the carbonated beverage contents can be poured from the discharge opening and into a glass or other drinking vessel.  
         [0077]     The pressurizing beverage dispenser device of the present invention removably attaches to the threaded neck N of the carbonated beverage container and replaces the conventional cap which is fastened to the neck N of the bottle B when the beverage product is purchased. The device  10  includes a main body  12  which is molded to include an integral handle portion  14  and a head portion  16 . In a preferred embodiment, the main body  12  is formed of a plastic composition and is molded as a two-piece structure, including a first half  20  and a second half  22 . The two halves  20 ,  22 , mate together, as illustrated in  FIG. 5 , to form the integral handle portion  14  and head portion  16  as well as to contain the remaining component elements of the device. Screws  24  can be used to secure the two halves  20 ,  22  together. The screws pass through apertures  26  formed through the first half  20  and into threaded engagement with aligned threaded bosses  28  on the interfacing side of the second half  22  of the main body  12 .  
         [0078]     When the beverage container B is initially opened, after purchase, by removing the conventional cap from the threaded neck N, the conventional cap is discarded and the device  10  is fastened to the threaded neck N. A seal mechanism within the head portion  16  provide an air and liquid tight seal between the dispenser device  10  and the discharge opening of the beverage container B in order to contain and preserve the beverage contents therein. The seal mechanism includes a cap  30  and a valve assembly  48 . The cap  30  is fitted within the head portion and includes interior threads  36  for threaded engagement and attachment to the threaded neck N of the beverage container B until the top rim of the beverage container neck surrounding the discharge opening mates against an inner cap end surface  37 . A central opening  38  through the top of the cap aligns with the discharge opening of the beverage container B. An annular ring  40  is formed on the top of the cap, surrounding the central opening  38 , and is provided with a slotted opening  42 . Wing members  44  are provided on opposite sides of an annular collar  34  of the cap, extending upwardly from a base flange  32 . The wing members  44  are specifically structured to prevent rotation of the cap relative to the main body  12  when the cap  30  is threadably secured to the neck N of the beverage container B to effectively secure the device  10  to the beverage container B.  
         [0079]     As seen in  FIG. 5 , the entire valve assembly  48 , including the cap  30  is held within the head portion  16  of the device  10  between the two halves  20 ,  22 .  
         [0080]     The valve assembly  48  further includes a pivotal valve spout  50  moveably secured to the head portion and operable between a closed, sealed position and an open position. The pivotal valve spout  50  is defined primarily by a ball-shaped portion  52  and a lever  54  extending outwardly from the top half of the ball-shaped portion  52 . A fluid flow passage  55  is formed through the ball-shaped portion  52  and is specifically structured and disposed for permitting flow of the beverage contents of the bottle B therethrough when pouring the beverage product from the bottle. Hinge stubs  56  on opposite sides of the ball-shaped portion  52  are structured and disposed for captivated, freely rotatable receipt within correspondingly aligned apertures  57  on the first and second halves  20 ,  22  of the head portion  16 . Receipt of the hinge stubs  56  within the apertures  57  serves to secure the valve spout  50  to the head portion  16 , while providing for selective, pivotal movement of the valve spout  50  between the closed, sealed position, as seen in  FIG. 1 , and the open position as seen in  FIG. 2 . The extending lever portion  54  facilitates ease of movement between the closed, sealed position and the open position. A front lip  58  on the head portion  16  provides a stop member to limit downward movement of the valve spout at the closed, sealed position. Similarly,, a back edge  59  on the head portion  16  provides a stop member to limit movement of the valve spout  50  at the fully open position, as seen in  FIG. 2 .  
         [0081]     The valve assembly  48  further includes a seal assembly  60  for maintaining an air tight and liquid tight seal between the valve spout  50  and the central opening  38  of the cap  30  in order to contain the beverage within the bottle B and to maintain the pressurized state of the air space within the bottle B when the valve spout  50  is in the closed position. The seal assembly  60  is comprised of a two-piece structure, including a flexible resilient seal member  62  and a rigid ring member  64 . In a preferred embodiment, the flexible resilient seal member  62  is formed of an elastomeric composition, such as silicon. The rigid ring member  64  may be formed of a rigid plastic composition similar to that of the cap  30 . The flexible resilient seal member  62  includes an upper portion  66 , a lower portion  68  and a neck  70  defined by a section of reduced diameter extending between the upper and lower portions. A dish-shaped concave annular surface  72  is formed on the upper portion  66  in surrounding relation to an opening  73 . The dish-shaped concave portion  72  defines a valve seat for mating engagement with the ball-shaped portion  52  of the valve spout  50 . The flexible resilient seal member  62  is fitted to the rigid ring member  64  during assembly of the device  10 . Specifically, the lower portion  68  of the seal member  62  is passed through an opening  78  of the ring member  64 . The opening  78  is surrounded by an inner rim  74  having a top rim surface  76 . When the seal member  62  is properly fitted to the ring member  64 , the lower portion  68  of the seal member  62  is maintained below the inner rim  74  and the upper portion  66  of the seal member is maintained above the inner rim  74 . The inner rim  74  surrounds the neck  70  of the seal member  72  so that an aperture  84  formed through the neck  70  aligns with an inner open end of a hollow stem  80  extending from the ring member  64 . The hollow stem  80  includes an enlarged head  82  at the free distal end. The combined seal member  62  and rigid ring member  64  of the seal assembly  60  sits on the top of the cap  30  so that an underside of the lower portion  68  of the seal member  62  mates firmly with the top surface  31  of the cap  30 , thereby providing an air and liquid tight seal between the seal assembly  60  and the cap  30 . When the seal assembly  60  and cap  30  are properly positioned and secured within the head portion  16  between the two halves  20 ,  22 , the slotted opening  42  aligns with the aperture  84  and hollow stem  80  to provide air flow communication between the open distal end at the enlarged head  82  of the hollow stem  80  and the central opening  38  of the cap which communicates with the discharge opening and interior of the beverage container B.  
         [0082]     An air pump mechanism  90  is provided for introducing air into the interior air space of the beverage container, between the surface of the liquid beverage and the discharge opening of the container B in order to pressurize the air space when the valve assembly  48  is in the closed, sealed position, thereby maintaining the carbonated gas within the liquid beverage. The air pump mechanism  90  includes a hand-operated squeeze bulb pump  92  secured to the handle portion  14 . The squeeze bulb pump  92  includes a central hollow body  94  surrounding a compressible interior air chamber, a first end portion  96  and an opposite second end portion  98 . The second end portion of the squeeze bulb pump is provided with a multi-sided outer surface for keyed receipt within congruent shaped notches  112  formed in the mating first and second halves  20 ,  22 . In a preferred embodiment, the multi-sided outer surface of the second end portion includes four sides  99   a,    99   b,    99   c,  and  99   d  as best seen in  FIG. 4 . Specifically, the four sides  99   a - 99   d  are arranged to define a generally square configuration to the second end portion  98 .  
         [0083]     The first end portion  96  of the squeeze bulb pump  92  is fitted with a one-directional air intake valve member  100  which is structured and disposed to draw air into the compressible interior chamber of the squeeze bulb as the central hollow body is released from a compressed state and returned to a normally, relaxed full shape. The second end portion  98  of the squeeze bulb pump  92  is fitted with a one-directional air exhaust valve member  102  which directs air outwardly from the squeeze bulb interior chamber when compressing and collapsing the hollow body. A hollow needle stem  104  extends from the exhaust valve member  102  to facilitate connection of a flexible air hose  106  which extends between the exhaust valve member  102  and the hollow stem  80 . More specifically, the needle stem  104  is received within one end of the flexible hose  106  while the enlarged head  82  of the hollow stem is inserted within the opposite end of the hose  106 , so that the flexible hose  106  remains connected in airflow transfer relation between the exhaust valve member  102  and the hollow stem  80 , thereby providing airflow communication between the compressible interior air chamber of the squeeze bulb pump and the interior air space within the beverage container B.  
         [0084]     The keyed fitting of the multi-sided exterior surface configuration of the second end portion of the squeeze bulb pump within the congruently configured notches  112  in the handle portion prevent the squeeze bulb pump  92  from spinning or rotating relative to the handle portion  92  when operating the squeeze bulb pump. Specifically, upon compressing and releasing the body of the squeeze bulb pump, the opposite first and second end portions  96 ,  98  of the squeeze bulb pump remain stationary relative to the main body  12  of the device. Specifically, the keyed fitting of the second end portion  98  to the handle portion  14  prevents spinning or rotation of the squeeze bulb pump  92  relative to the handle portion  14 , thereby preventing the flexible hose from becoming twisted and/or kinked during use of the device  10 , which may otherwise result in blockage of airflow between the squeeze bulb pump and the air space within the beverage container interior. A collar  110  formed on the end of the handle portion  14  of each of the first and second halves  20 ,  22  surrounds and grasps the first end portion  96  of the squeeze bulb pump  92  to firmly secure the first end portion thereto. Accordingly, the squeeze bulb pump  92  is held as an integral component of the handle portion  14 .  
         [0085]     Alternative mechanisms for preventing rotation of the squeeze bulb include an adhesive, coupling to a rigid or semi-rigid tube, etc.  
         [0086]     In use, the dispenser device  10  of the present invention is threadably fastened to the neck N of the beverage container B. With the valve spout  50  moved to the closed position, as shown in  FIG. 1 , a charge of air is introduced into the interior air space of the bottle B by repeatedly squeezing and releasing the hand-operated squeeze bulb pump  92  on the handle portion  14  until the air space within the container B is fully pressurized. The fully pressurized condition will be realized when there is increased resistance in compressing the squeeze bulb pump. Mating engagement of the ball-shaped portion  52  of the valve spout  50  against the valve seat  72  provides an air tight and liquid tight seal, holding the air pressure and liquid beverage contents within the beverage container B. When the valve spout is moved to the open position, as seen in  FIG. 2 , by grasping the lever portion  54  and lifting upwardly to rotate the valve spout approximately 90 degrees, the charge of pressurized air is released from the bottle B. While maintaining the valve spout in the open position, the carbonated beverage product within the container B may be poured by tilting the container so that the neck N is angled downwardly, thus allowing the beverage contents to flow through the passage  55  of the valve spout  50  and into a glass or other drinking vessel. After pouring the beverage, the valve spout  50  is again closed to seal the interior of the bottle and the hand-operated squeeze bulb pump is repeatedly squeezed and released to repressurize the bottle interior air space.  
         [0087]     Referring to  FIG. 6 , an alternative embodiment of the present invention is shown wherein the handle portion  14  and air pump mechanism  90  are incorporated within a siphon dispenser device  10 ′. In this embodiment, the handle portion  14  is integrally formed as part of a main body  12 ′ having a mechanism for threadable attachment to the top of a carbonated beverage container B′. The handle portion  14  and air pump mechanism  90  are identical to that which was described in connection with the embodiment of  FIGS. 1-5 . Specifically, the air pump mechanism  90  includes a hand operated squeeze bulb pump  92  secured to the handle portion  14 . The squeeze bulb pump  92  includes a central hollow body  94  surrounding a compressible interior air chamber, a first end portion  96  and an opposite second end portion  98 . The first end portion  96  is fitted with a one-directional air intake valve member  100  and the second end portion  98  is fitted with a one-directional air exhaust valve member  102 , the valve members  100 ,  102  functioning as described above. A hollow needle stem  104  extends from the exhaust valve member  102  to facilitate connection of a flexible air hose  106  which extends from the exhaust valve member  102  and connects for a fitting for air flow communication with the hollow interior of the beverage container B′. The collar  110  formed on the handle portion  14  surrounds and grasps the first end portion  96  of the squeeze bulb pump  92  to firmly secure the first end portion thereto. While not shown in  FIG. 6 , the second end portion  98  is keyed to the handle portion  14  in the same manner as described in connection with the embodiment of  FIGS. 1-5 , so that the squeeze bulb pump is unable to rotate relative to the handle portion  14 , thereby preventing twisting and kinking of the flexible hose  106 .  
         [0088]     To operate the siphon device  10 ′ of  FIG. 6 , the squeeze bulb pump  92  is compressed and relaxed through several cycles in order to introduce air, under pressure, into the interior air space of the beverage container B′. This serves to force the liquid contents upwardly through hollow tube  120  which has an open end disposed in close spaced relation to the bottom of the interior of the beverage container B′. The liquid beverage flows upwardly to valve member  122  which, when operated towards a fully open position, permits passage of the liquid beverage, under force, through the discharge opening  124 .  
         [0000]     Water Pistols  
         [0089]      FIGS. 7 and 8  illustrate yet another embodiment of the present invention, wherein the handle portion  14  and air pump mechanism  90  are incorporated within water pistols  200 . The structure of the handle portion  14  and air pump mechanism  90  are similar to the above-described embodiments of  FIGS. 1-6 . In this particular embodiment, the handle portion  14  is integrally formed with the body of water pistol  200 . The one-directional air exhaust valve member  102  on the second end portion  98  of the pump  92  connects with air hose  106 . The opposite end of the air hose  106  is connected in airflow communication with water tank  210  which is filled with water by removing fill cap  212 . In operation, the squeeze bulb pump  92  is operated by compressing and releasing the squeeze bulb to direct forced air into the water tank  210  through hose  106 , thereby causing the air tank to become pressurized. A discharge hose or conduit  214  leads from the bottom of the water tank  210  to conduit  220  and is interrupted by a valve  216 . The valve  216  is operable by a trigger  218  and is normally disposed in a relaxed, closed position, to block water flow from hose  214  to conduit  220 . Upon operating the trigger  218  with the index finger or thumb, the valve  216  is opened, permitting fluid flow passage of the water, under pressure, from the water tank  210  through hose  214  and through conduit  220  and exiting in a stream through discharge opening  224 . It should be noted that the trigger  218  in the pistol  200  of  FIG. 8  has been relocated from the position shown in  FIG. 7 , so as to be more accessible to actuation by the thumb of the user, thereby enabling the user to maintain a grip on the handle  14  while squeezing the squeeze bulb pump  92  and operating the trigger  218 . In either embodiment, the pump  92  and trigger  218  may be used independently or at the same time, while grasping handle  14  for control of spray direction. These actions can be done ambidextrously and at the same time using only one hand.  
         [0000]     Pump Handle  
         [0090]      FIG. 9  illustrates another embodiment of the present invention, in which, a bulb style air pump  310  is secured within a handle  311  and permits air to be pumped into bottle  312 . A trigger  313  is located on the top of the handle  311 . The pump handle includes a tube  316  which goes into the bottle  312  and is connected to a fitting  317  on the bottom of a female threaded cap  318 . Cap  318  is threadably engaged to male threads  342 . A collapsible tube  319  is connected to a fitting  320  on the outside of cap  318 . The opposing end of tube  319 , is connected to a fitting  343  of spray nozzle  321 . Pump  310  contains two check valves.  
         [0091]     Note that the terms “threaded,” “threadably engaged” and the like as used herein can refer to traditional threaded engagement (i.e., with a spiral-shaped protrusion extending out from each of the engaging surfaces), and can also refer to other types of attachment mechanisms such as twist locks, snap locks, tongue and groove-type arrangements, etc. of any kind.  
         [0092]     When the pump is squeezed, the top check valve  322  allows air out of the pump in one direction. When the pump returns to its bulb shape the bottom check valve  324  allows air into the pump. One end of tube  325  is connected to a fitting  323  of valve  322 , the opposing end of tube  325  is connected to a fitting  326  of cap  318 . For each pump stroke, air is forced out of check valve  322  into tube  325  and into bottle  312 . As pressure in bottle  312  is increased, the liquid within bottle  312  will seek a means of escape.  
         [0093]     To spray a liquid, as seen in  FIG. 12 , pressing trigger  313  down will pivot the trigger lever  327  at pivot point  328 , allowing tube  319  to open. Then the liquid will travel up tube  316 , through fitting  317 , out through fitting  320 , then through tube  319 , into fitting  343  and dispensed out through a perforation  344  of nozzle  321 .  
         [0094]     To close the valve, as seen in  FIG. 9 , the compression spring  314  expands forcing lever  327  to pivot downward closing valve  315  and collapsing tube  319 . At this point valve  315  is in the closed position.  
         [0095]     To control the flow of and volume of liquid, as seen in  FIG. 9 , turning nozzle  321  in one direction creates a lower volume liquid mist and turning nozzle  321  in the opposite direction creates a liquid stream with more volume.  
         [0096]     The nozzle  321  in this and other embodiments may also form a fan spray, i.e., a generally dove-tail shaped spray stream having a generally oval to rectangular spray pattern, as opposed to the typical round spray pattern formed by a conical spray stream. The fan spray is particularly useful for producing even spray coverage over large areas, and is especially effective because the fluid is discharged under pressure.  
         [0097]     The nozzle  321  in this and other embodiments may also form a foam. An illustrative foaming nozzle is described in U.S. Pat. No. 4,646,973 to Focaracci and is herein incorporated by reference.  
         [0098]     Pump  310  and trigger  313  may be used independently or at the same time, while grasping handle  311  for control of spray direction, these actions can be done ambidextrously and at the same time using only one hand.  
         [0099]     In  FIGS. 10 and 11 , the cube shape top  329  of pump  310  secures the bulb within handle  311  ( FIG. 9 ), and will not allow it to spin or rotate when pumped. If the pump was permitted to spin or rotate, then tube  325  ( FIG. 9 ) would become kinked, blocked, or even disconnected and thus not permitting air to enter into bottle  312  ( FIG. 9 ) resulting in a nonfunctional pump handle.  
         [0100]     Another embodiment of the present invention includes an atomizer. To achieve an aerosol effect for dispensing dense liquids such as cleaning solutions, paint and oils, a pump handle is combined with an atomizer. An atomizer is very effective in achieving a mist when spraying cleaners, food oils and paints. A trigger on the outside center of the handle is engaged to the atomizer spray head. When the trigger is pressed down, the spray head will push down on the atomizer valve and allow the liquid to be propelled through the spray head. The pump and trigger may be used independently or at the same time, while grasping the handle for control of spray direction, these actions can be done ambidextrously and at the same time using only one hand.  
         [0101]     As seen in  FIGS. 9 and 11 , the surface area of pump  310  is generally rounded; the direction of force exerted by the action of pumping may accidentally come from a side angle. If not properly secured, these forces would spin the pump causing twisting of tube  325 . Winding and twisting of tube  325  would cause an air blockage or would cause tube  325  to disconnect from fittings  323  and  326 .  
         [0102]     To prevent pump  310  from spinning or rotating within handle  311  during manual pumping of pump  310 , in  FIG. 10 , the top of pump  310  is cube shaped  329 . As seen in  FIGS. 13 and 14 , the components which make up the basic pump handle assembly without a trigger are illustrated, a bulb air pump  310  with a top cube shape  329 , internal check valves,  324 ,  322 . Pump  310  with the internal check valves  324  and  322  are partially enclosed within the housing of sections  311 A and  311 B of the handle. Male threaded screws  344  are matted to female threaded holes  345  to secure sections  311 A and  311 B together. A cube shape  346  is internally formed into the inside of sections  311 A and  311 B of the handle and when assembled, is designed to match cube shape  329 . The matching cube shape restricts any rotational movement of pump  310 . Tube  325  connects to fitting  323 . The pump handle assembly as seen in  FIGS. 13 and 14  may be formed and fitted to become integral of a host device.  
         [0103]     The pump handle may have many uses and should not be limited to the embodiments disclosed. The pump handle provides an ambidextrous way to hold, grasp, and manipulate an object with one hand and transfer air into that object using the same hand. With the addition of triggers, the pump handle will allow a user to grasp, pump, and press a trigger with the use of one single hand. There are many devices that can be fitted and formed to be used with the pump handle. These devices include but are not limited to, toys, plant sprayers, water sprayers, chemical sprayers, insecticide sprayers, paint sprayers, food oil misters, hair spray, and the like.

Intake check valve  424  is positioned adjacent to check valve  422 . Lip  474  extends over. When pump  491  is manually squeezed, pump  491  collapses forcing check valve  422  to open as the flow of air is directed out of fitting  423 , check valve  424  remains closed. When pump  491  is manually released, pump  491  will return to its original shape drawing air in as check valve  424  is opened, check valve  422  remains closed. As seen in  FIGS. 21, 22 , and  23 , the top portion of pump  491  may be cube shaped  429 . Pump  491  may be composed of rubber, silicone, or the like.  
         [0107]     As shown in  FIGS. 24-30 , a pump sprayer is threadably engaged to bottle  412 . Male threads  442  of bottle  412  match the female threads of cap  418  to secure the sprayer to bottle  412 . Pump  410  ( FIGS. 24-26 ) is secured within handle  411  and housing  462 . Exhaust check valve  422  is housed within fitting  423  and intake check valve  424  is located at the bottom of pump  410 . The intake check valve  424  can be held in place by the handle  411 , and may be substantially hidden from view by the handle  411 , which then would also act as a shield to the intake valve  422 , protecting the intake valve  422  from dirt or anything that could interfere with proper operation of the pump. Fitting  423  is connected to tube  425  and the opposing end of tube  425  is connected to fitting  420  of threaded cap  418 . Fitting  443  of spray nozzle  421  is connected to a collapsible tube  419  and the opposing end of tube  419  is connected to fitting  426  of threaded cap  418 . Trigger  413  is designed to be used with the index finger. Trigger  413  is formed integral with trigger arm  492  which extends across and is connected to compression spring  414 .

Tube  416  extends into bottle  412  and is attached to the pump sprayer at inside fitting  417  of threaded cap  418 . All the components of the pump sprayer are enclosed within housing  462 . When pump  410  is manually squeezed, check valve  424  closes and check valve  422  opens to allow air flow to enter tube  425  out of fitting  423 . The air flow will then enter bottle  412  through fitting  420 . When pump  410  is manually released, the increased air pressure on the outside of check valve  422  will force check valve  422  to close. As the pump returns to its bulb shape, check valve  424  will open to allow air into the chamber of pump  410 . With each stroke of pump  410 , the air pressure will increase in bottle  412 . The bottle will reach full pressurization when pump  410  feels slightly firm to the touch. As seen in  FIG. 25 , when trigger  413  is manually pressed in, arm  492  will slide back and compress spring  414  to open pinch valve  415 . The air pressure in bottle  412  will force liquid  494  to travel up tube  416  through fittings  417  and  426  then into tube  419 . The liquid will then travel from tube  419  through fitting  443  of nozzle  421  and out of perforation  480  into the ambient atmosphere or desired spray surface. When the trigger is manually released, spring  414  will push arm  492  forward to compress tube  419  and close pinch valve  415 . To spray intermittently, trigger  413  may be pressed repeatedly until all of the air pressure has been released from the bottle. To spray continuously, the trigger may be held pressed in for a longer duration until all of the air pressure has been released from the bottle. As shown in  FIG. 26 , handle  411  is a formed integral with housing  462  and forms a full handle. Handle  411  fully surrounds the bottle neck portion of bottle  412 . Release valve  439  can be used to release air pressure from the bottle  412 .  
         [0108]      FIGS. 27 and 28  illustrate another embodiment in which pump  490  is attached to handle  411 . In this embodiment handle  411  forms a half handle and the bottle neck of bottle  412  forms the rest of the handle. In  FIGS. 19 and 20  pump  491  is attached to housing  462 . In this embodiment the bottle neck of bottle  412  forms handle  411 .  
         [0109]     In the embodiments as shown in  FIGS. 31-33 , pump  491  is located at the top corner of the pump sprayer. As shown in the embodiment in  FIGS. 34 and 35 , pump  491  is located towards the back corner of the pump sprayer. In  FIGS. 36 and 37 , pump  410  is located towards the back corner of the pump sprayer. As seen in  FIGS. 38 and 39 , pump  410  is located towards the back corner of the pump sprayer and held in place by a rigid handle  493 .  
         [0110]     In  FIGS. 40-46 , a pump sprayer is threadably engaged to bottle  412 . Male threads  442  of bottle  412  match the female threads of cap  418  to secure the sprayer to bottle  412 . Pump  491  ( FIGS. 40-42 ) is secured within housing  462 . Exhaust check valve  422  is housed within fitting  423  and intake check valve  424  is adjacent valve  422 . Fitting  423  is connected to tube  425  and the opposing end of tube  425  is connected to female fitting  420  of threaded cap  418 . Fitting  443  of spray nozzle  421  is connected to a collapsible tube  419  and the opposing end of tube  419  is connected to fitting  426  of threaded cap  418 . Trigger  413  is on top and is designed to be used with the thumb. Trigger  413  is formed integral with lever  427  which extends across and pivots up and down at pivot point  428 . Spring  414  forces lever  427  down to collapses tube  419  to form a pinch valve  415 . Tube  416  extends into bottle  412  and is attached to the pump sprayer at female fitting  417  of threaded cap  418 . All the components of the pump sprayer are preferably enclosed within housing  462 . The bottle neck of bottle  412  forms the handle. When pump  491  is manually squeezed, check valve  424  closes and check valve  422  opens to allow air flow to enter tube  425  and out of fitting  423 . The air flow will then enter bottle  412  through female fitting  420 . When pump  491  is manually released, the increased air pressure on the outside of check valve  422  will force check valve  422  to close. As the pump returns to its bulb shape, check valve  424  will open to allow air into the chamber of pump  491 . With each stroke of pump  491 , the air pressure will increase in bottle  412 . The bottle will reach full pressurization when pump  491  feels slightly firm to the touch. As seen in  FIG. 41 , when trigger  413  is manually pressed down, lever  427  will pivot at pivot point  428  compress spring  414  to open pinch valve  415 . The air pressure in bottle  412  will force the liquid to travel up tube  416  through fittings  417  and  426  then into tube  419 . The liquid will then travel from tube  419  through fitting  443  of nozzle  421  and out of perforation  480  into the ambient atmosphere or desired spray surface. When the trigger is manually released, spring  414  will push lever  427  down to compress tube  419  and close pinch valve  415 . To spray intermittently, trigger  413  may be pressed repeatedly until all of the air pressure has been released from the bottle. To spray continuously, the trigger may be held pressed in for a longer duration until all of the air pressure has been released from the bottle. As shown in  FIG. 42 , the bottle neck of bottle  412  forms handle  411 . In the embodiment as shown in  FIGS. 43 and 44 , pump  410  is located towards the front bottom corner and is held in place by housing  462 . As seen in  FIG. 44 , handle  411  is formed integral with housing  462 . In the embodiment as shown in  FIGS. 45 and 46 , pump  490  is located towards the front bottom corner and is held in place by housing  462 . Handle  411  forms a half handle and the bottle neck of bottle  412  forms the rest of the handle.  
         [0111]     In a disposable, single use version, the pump sprayer/container combination could be fashioned such that the container cannot be refilled without damage to at least one of the components that make up the pump sprayer/container combination. This can be accomplished by using one-way snap locks that must be deformed or broken to separate.  
         [0112]      FIGS. 47-49  illustrate another type of pumping mechanism. As shown in  FIG. 47 , the pump includes a collapsible bellows pump  502  coupled to a handle  504 , and also preferably a hinged handle  506  that is biased towards an open position (as shown in  FIG. 47 ). Referring to  FIG. 48 , the bellows pump can have a generally rectangular shape, but can also be formed in other shapes such as triangular, round, etc.  
         [0113]     Referring again to  FIGS. 47 and 49 , an intake valve  508  and exhaust check valve  510  function generally as described above in the prior embodiments to direct air out of the bellows pump  502  upon collapse and into the air tube  512  connected to the interior of the container to which attached.  FIG. 49  illustrates the pumping mechanism with the hinged handle  506  forced towards the handle  504 , thereby compressing the bellows pump  502 .  
         [0114]     In a variation of the pump mechanism shown in  FIGS. 47-49 , a collapsible diaphragm, bulb, etc. instead of a bellows could be positioned between the handle  504  and hinged handle  506 .  
         [0115]     In a further variation of the pump mechanism shown in  FIGS. 47-49 , the hinged handle  506  could be replaced with a moveable handle that does not necessarily pivot when it is pulled back towards the handle  504 . The moveable handle would follow one or more guides (e.g., pegs, channels, etc.) that guide the moveable handle towards the handle  504  to compress a collapsible pump.  
         [0116]      FIGS. 50-53B  depict a spraying device with an alternate trigger mechanism  522  having a lock-open feature. Any of the pump mechanisms described above can be used with this embodiment.  FIG. 50  illustrates the trigger mechanism  522  in a closed position. As shown, the trigger mechanism  522  includes a pinch valve  524  for selectively releasing the contents of the container  526  and a spring  525  for biasing the pinch valve towards the closed position. Other types of valves can also be used. A trigger  528  is actuated by the user to selectively open and close the pinch valve.  FIG. 51  illustrates the pinch valve  524  being open when the trigger  528  is actuated.  
         [0117]     The trigger  528  can preferably be locked in the actuated position by some type of locking mechanism.  FIG. 52  illustrates one type of locking mechanism, where the trigger  528  includes a member  530  that hooks on a lip, peg, etc. In the embodiment shown, a portion of the trigger  528  slides slightly towards the pump to engage the member  530  with a peg  532 . Alternatively, a sliding clip in the handle could engage the trigger to hold the trigger in an open position.  
         [0118]      FIGS. 53A and 53B  illustrate various parts and corresponding subassemblies of the spraying device of  FIGS. 50-52 .
