Abstract:
A hand operated air pump apparatus comprising an internal bellows in communication with an outer bellows wherein variable force on air pump forces compressed air through a discharge valve into a annulus between a bottle and a flexible bladder wherein said pump is attached upon a container or bottle like vessel wherein pumping action forces from bottle highly viscous substances, that may contain solid or abrasive particles, through a discharge spout without internal substance being contaminated by air or other environmental factors thus allowing for an improved method of removing all contents within a container with greater ease.

Description:
BACKGROUND OF THE INVENTION 
   1.) Field of the Invention 
   This invention relates generally to jars, bottles, and tubes of highly viscous and or thixotropic liquids, such as hand lotions, toothpaste, greases, and expensive cosmetic lotions to be dispensed and more specifically details an improved novel method of pumping these liquids that may contain solids or abrasive particles from their containers. 
   One problem with existing dispensers is that most hand lotion bottles come with vertical reciprocating hand pumps that will pump the viscous liquid while the bottle is full. As the level of the lotion, or viscous liquid, drops in the bottle the hydrostatic head pressure on the suction side of the pump decreases and the pump quits pumping efficiently, leaving expensive liquid in the bottle which is wasteful to the consumer. 
   A second problem is that vertical reciprocation hand pumps only allow the viscous liquid to be pumped while the container bottle is in a vertical position. 
   A third problem is that vertical reciprocation hand pumps allow atmospheric air to be exposed to the viscous liquid in the lotion bottle drying it out. 
   A fourth problem is that vertical reciprocation hand pumps allow atmospheric air to be exposed to the viscous liquid in a bottle contaminating the sterilized viscous liquid. 
   A fifth problem is that many expensive cosmetic lotions, or viscous liquids, require chemical extenders, thinning agents, and or plasticizers, in various expensive combinations, to reduce the viscosity of the liquid so that it may be pumped. This adds to the cost of the viscous liquid and requires a larger bottle that must be purchased, filled, handled, labeled, stored, &amp; transported which is wasteful. 
   A sixth problem is that viscous liquids produced in squeeze bottles or tubes are effected by atmospheric pressure and temperature changes which may cause the viscous liquid to be inadvertently expelled from the tube or bottle which is wasteful. 
   A seventh problem is that highly viscous and or thixotropic liquids offered in open topped jars with snap on or screwable lids are open to the atmosphere while being dispensed contaminating the sterilized viscous liquid. 
   A eight problem is that weak, arthritic, elderly, or physically challenged people sometimes have a very difficult time generating sufficient hand forces to squeezing tubes of highly viscous materials or generating a sufficient twisting motions to remove and replace screwable lids containing needed material. 
   Therefore, the primary objective of this novel invention is to eliminate all of the above problems by using compressed air generated by a small air pump on the container bottles to squeeze a bladder forcing the highly viscous and or thixotropic liquids non contaminated liquid from the bottle in any attitude, vertical horizontal, or rotated at any angle. 
   A second object of this invention is to allow an individual to operate the lotion pump with one finger or hand. 
   A third object of this invention is to release the hand-pumped up compressed air, by stopping the pumping action and removing the hand or finger from the lotion pump, which will stop the dispensing of the vicious liquid. 
   2.) Description of the Related Art 
   U.S. Pat. No. 7,137,531 B2 Relates to a flexible bag commonly called a “bag-in-a-Box”, in the art, that is used to displace fluids such as wine and liquid soaps. The bag is not compressed by external pressure to discharge the liquids and does not relate to this invention. 
   U.S. Pat. No. 6,460,739 B2 relates to a dispenser for viscous or viscous products, liquids, which has a closure, which closure automatically closes the dispenser exit and relates to closures which this invention does not specifically relate to. 
   U.S. Pat. No. 6,073,804 relates to a device for packaging and dispensing a fluid that includes a shrinkable bag suitable for shrinking as the quantity of viscous fluid contained inside it diminishes, and an extraction means opening out to the inside of the bag. The bag is shrunk or squeezed by a propellant gas that as we know is hazardous to fill, transport and store and sometimes harmful to the environment. U.S. Pat. Nos. 4,793,522; 4,872,596; and 4,890,733 all relate to pumping viscous products that use a floating piston that is driven into the displaced product by atmospheric pressure. The product being displaced by a positive displacement pump relies on the seal of the floating piston to keep the suction side of the pump primed. We all know that sliding seals of any kind eventually leak which renders these types of dispensers for viscous liquids ineffective. 
   SUMMARY OF THE INVENTION 
   In accordance with the invention a small hand operated air pump is mounted on a dispenser bottle. By application of a variable pumping force on the top of the air pump, the air pump pumps compressed air into an annulus, between the dispenser bottle, and flexible bladder that contains the viscous liquid, that may contain solid or abrasive particles, squeezing the flexible bladder. 
   Squeezing the flexible bladder, with compressed air in the annulus, forces the viscous liquid, up a dispenser tube, through the discharge spout, through a flex disk, and into a receiving vessel or a hand. 
   From the foregoing, it will be apparent that the present invention provides for a novel and unique means for dispensing viscous substance with the added benefit of keeping the substance contaminate free. 
   Whereas the present invention has been described in particular relationship to the drawings attached hereto, it should be understood that other and further modifications apart from those shown or suggested herein may be made within the scope of the invention and its claims.

   DETAILED DESCRIPTION OF THE INVENTION 
   Referring now to  FIG. 1 . The portion of the invention above line B-B is referred to as the air pump  162 . The portion of the invention below line B-B is referred to as the container bottle  130 . The invention is shown in the “at rest” position which is explained below in  FIG. 4 . 
   Referring now to  FIG. 2 .  FIG. 2  is a top view of  FIG. 1 . Line A-A is a section line that shows arrowheads indicating the direction of views described in detail in the figures below. Line B-B is a section line that shows arrowheads indicating the direction of views described in detail in the figures below. 
   Referring now to  FIG. 3  is an overview of the invention. The air pump  162  is shown in on its downward “pumping stroke” position in  FIG. 3 . By application of a variable pumping force  163 , the air pump  162  (described in detail in  FIGS. 4 ,  5 , &amp;  6 ) pumps compressed air into the annulus  161 , between the container bottle  130 , and flexible bladder  140 , that contains the viscous liquid  160 , that may contain solid or abrasive particles (not shown), squeezing the flexible bladder  140 . 
   Still referring to  FIG. 3 . Squeezing the flexible bladder  140 , with compressed air in the annulus  161 , forces the viscous liquid  160 , up the tube  120 , in the direction of arrows A, through the discharge spout  90 , through the flex disk  100 , and into a receiving vessel or a hand (not shown). 
   Referring now to detailed description of the air pump  162  using  FIGS. 4 ,  5 , &amp;  6 . 
   Referring now to  FIG. 4 .  FIG. 4  shows the air pump  162  in its up “at rest” position. The top cap  10 , is in it&#39;s “at rest” up position as there is no downward variable pumping force  163  ( FIG. 3 ), in the up “at rest” position. The interior bellows  40 , has been so designed, spaced &amp; constructed that in the air pumps up “at rest” position, a residual bellows force  168  is generated by the interior bellows  40  trying to expand further upward but can&#39;t as it is restrained by the top cap  10  and the fully expanded exterior bellows  30 . The residual bellows force  168  is held, restrained, by the guide fingers  12  ( FIG. 9 ) of the top cap  10 , acting on the bottom  21  of the pump top  20  ( FIG. 7 ). 
   Still referring to  FIG. 4 . The exterior bellows  30  has been glued or welded to the interior surface  24  of the outside ring  22  of the pump top  20  ( FIG. 7 ) which is air tight. 
   Still referring to  FIG. 4 . The exterior bellows  30  has been glued or welded to the interior surface  57  of the outside ring  53  of the pump bottom  50  ( FIG. 8 ) which is air tight. 
   Still referring to  FIG. 4 . The interior bellows  40  has been glued or welded to the outside surface  16  of the inner ring  15  of the top cap  10  ( FIG. 9 ) which is air tight. 
   Still referring to  FIG. 4 . The interior bellows  40  has been glued or welded to the outside surface  58  of the inside ring  54  of the pump bottom  50  ( FIG. 8 ) which is air tight. 
   Still referring to  FIG. 4 . In the “at rest” position the discharge valve  70  has its sealing surface  71  ( FIG. 10 ) sealing against the sealing surface  55  of the pump bottom  50  closing off the annulus discharge holes  60  ( FIG. 8 ). 
   Still referring to  FIG. 4 . The discharge valve  70  is so constructed that it&#39;s outside sealing surface  71  ( FIG. 10 ) is slightly larger, on the diameter, than the inside sealing surface  55  of the pump bottom  50  ( FIG. 8 ) and is therefore slightly preloaded in the closed sealing position as shown in  FIG. 4 , the “at rest” position. 
   Still referring to  FIG. 4 . In the “at rest” position the suction valves  110  outside sealing surface  111  ( FIG. 11 ) is sealing against the sealing surface  56  of the pump bottom  50  ( FIG. 8 ) closing off the suction air holes  51  ( FIG. 8 ). 
   Still referring to  FIG. 4 . The suction valve  110  is so constructed that it&#39;s outside sealing surface  111  ( FIG. 11 ) is slightly larger than the inner sealing surface  56  of the pump bottom  50  ( FIG. 8 ) and is therefore slightly preloaded in the closed sealing position as shown in  FIG. 4  the “at rest position.” 
   Still referring to  FIG. 4 . As may be seen in  FIG. 4  the air pump  162  ( FIG. 1 ) discharge hole  52  of the pump bottom  50  ( FIG. 8 ) is open to the atmosphere through the interior space  166  of the interior bellows  40 , through the inside of the top cap  10  through the air bleed holes  11  of the top cap  10  ( FIG. 9 ) so that ambient temperature fluctuations will not expand or contract any trapped air causing it to expand or contract against the outside of the flexible bladder  140  ( FIG. 3 ), possibly causing the viscous liquid  160  to be discharged from the container bottle  130  ( FIG. 3 ). 
   Still referring to  FIG. 4 . As may be seen in  FIG. 4  the air suction holes  51  of the pump bottom  50  ( FIG. 8 ) seals off the bellows annulus  165  when the air suction valve  110  ( FIG. 11 ) is in its closed position as shown. 
   Still referring to  FIG. 4 . Ambient temperature fluctuations acting on the trapped air in the bellows annulus  165  will, if the temperature increases, cause the trapped air to expand which will slightly open the discharge valve  70  ( FIG. 10 ) relieving any trapped air pressure through the air bleed holes  11  in the top cap  10  ( FIG. 9 ). If the ambient air temperature decreases, the trapped air in the bellows annulus  165  will decrease in volume and slightly open the suction valve  110  equalizing the air pressure. Therefore, ambient temperature swings will not cause the trapped air in the bellows annulus  165 , or the air trapped in the interior space  166  to act on the flexible bladder  140  in any manner. 
   Referring now to  FIG. 5 .  FIG. 5  shows the air pump  162  on its “pumping stroke” which requires a sufficient air pressure to be generated to pump the viscous liquid  160  ( FIG. 3 ). The required air pressure requires that a sufficient variable pumping force  163  be generated as shown. 
   Still referring to  FIG. 5 . At the beginning of the “pumping stroke” the bottom  13  of the top cap  10  ( FIG. 9 ) is pushed against the top  23  of the pump top  20  ( FIG. 7 ) overcoming the residual bellows force  168  ( FIG. 4 ) which seals off the air bleed holes  11  ( FIG. 9 ) and traps the air pressure generated by the variable pumping force  163 . 
   Still referring to  FIG. 5 . The required downward variable pumping force  163  is generated (by a hand or finger—not shown) to produce the required air pressure to pump the viscous liquid  160  ( FIG. 3 ). 
   Still referring to  FIG. 5 . Now, with the variable pumping force  163  acting throughout the limit of the downward stroke the air being compressed in the bellows annulus  165  forces the discharge valve  70  to open. The compressed air in the bellows annulus  165  follows arrow A. The air being compressed in the interior space  166  passes through the interior of the open discharge valve  70 , as shown by arrow B. Both air streams, A &amp; B, pass through the pump discharge hole  52  in the pump bottom  50  ( FIG. 8 ), through the bottle cap  80  ( FIGS. 3 ,  13 , &amp;  15 ) and, into the annulus  161  ( FIG. 3 ) between the container bottle  130  ( FIG. 16 ) and the flexible bladder  140  ( FIG. 19 ). 
   Still referring to  FIG. 5 . When the air pump  162  reaches the limit or bottom of its downward stroke (not shown) the compressed air, from air streams A &amp; B, ceases to flow. The air stream A ceases to flow around the discharge valve  70  and it closes against its sealing surface  55  ( FIG. 8 ). Also, at this instant, the suction valve  110  remains closed against its sealing surface  56  of the pump bottom  50  ( FIG. 8 ) as it has during the downward pumping stroke. The suction valve  110  has been held closed by the air pressure generated in the bellows annulus  165 . No compressed air is flowing at the instant of the end of the pumping stroke as both the suction valve  110  and the discharge valve  70  are closed. 
   Referring now to  FIG. 6 .  FIG. 6  shows the position of the air pump  162  just after the instant of the beginning its upward “suction stroke”. The suction valve  110  opens, as shown, due to the negative pressure generated in the bellows annulus  165  as the air pump  162  moves upward. The discharge valve  70  is held closed by the internal air pressure in the interior space  166  that was generated by the first, and subsequent, downward “pumping strokes”. Also at this instant, and throughout, the upward “suction stroke” the bottom  13  of the top cap  10  ( FIG. 9 ) must be held against the top  23  of the pump top  20  ( FIG. 7 ), which seals off the air bleed holes  11  ( FIG. 9 ), to maintain any previously generated air pressure in the interior space  166  of the air pump  162 . When another downward “pumping stroke” is started the air pump  162  instantly reverts back to the beginning of the downward “pumping stroke as shown and describe in  FIG. 5 . 
   Still referring to  FIG. 6 . By continuing “pumping strokes” ( FIG. 5 ) and “suction strokes” ( FIG. 6 ) of the air pump  162  the total amount of viscous liquid may be expelled from the container bottle  130  at one time, or at several intermediate times. 
   Referring to  FIGS. 1 ,  2 ,  3 ,  4 ,  5 , and  6 . It should be noted that for any given size of a container bottle  130 , for any given size of a flexible bladder  140 , and a any given viscosity of the viscous liquids  160 , at a given ambient temperature and atmospheric pressure, the required volume of air, and the pressure of the air, in the annulus  160 , necessary to collapse the flexible bladder  140 , will be dependent on the diameters and height of the interior and exterior bellows,  40  and  30  respectively. 
   Referring now to  FIG. 7 .  FIG. 7  shows the pump top  20 , the top of the pump top  23 , the outside ring  22 , the interior surface  24 , and the bottom of the pump top  21 . 
   Referring now to  FIG. 8  shows the inside ring  54 , the outside surface of the inner ring  58 , the air suction holes  51 , the annulus discharge holes  60 , the inner surface  57 , the sealing surface  55  of the discharge valve  70  (not shown), the outside ring  53 , the sealing surface  56  of the suction valve  110  (not shown), the inside surface  62 , and the discharge hole  52  of the pump bottom  50 . 
   Referring now to  FIG. 9 .  FIG. 9  shows the air bleed holes  11 , the guide fingers  12 , the outside surface  16 , the inner ring  15 , and the bottom  13  of the top cap  10 . 
   Referring now to  FIG. 10 .  FIG. 10  shows the compression slot  73 , the locating dog  72 , and the sealing surface  71  of the discharge valve  70 . 
   Referring now to  FIG. 11 . The suction valve  110  has a compression slot  113 , and a locating dog  112 , similar to the discharge valve  70 , and is prevented from rotation in the same manner as the discharge valve  70  discussed above in  FIG. 12  but not shown here. 
   Referring now to  FIG. 12 .  FIG. 12  shows the pump bottom  50  in an isometric section along section line B-B as shown in  FIG. 2 . This view is of the pump bottom  50  ( FIG. 8 ) and the discharge valve  70  ( FIG. 10 ) only. The suction valve  110  ( FIG. 11 ) is not shown. The discharge valve  70  is shown “at rest” or closed. 
   Still referring to  FIG. 12 . The locating dog  72  of the discharge valve  70  ( FIG. 10 ) fits into the locating slot  59  of the pump bottom  50 . The locating dog  72  prevents the compression slot  73  ( FIG. 10 ) from rotation with use and lining up with the annulus discharge hole  60  which would cause the air pump  162  to leak and the air pump  162  would not function as designed. 
   Still referring to  FIG. 12 . The suction valve  110  (not shown) has a locating dog  112  (not shown) that fits interior to and adjacent to the air suction holes  51  that has a locating dog  112  (not shown) that operates as does the discharge valve  70  described in the above paragraph. 
   Referring now to  FIG. 13 .  FIG. 13  is composed of two parts, the pump bottom  50  ( FIG. 8 ) and the bottle cap  80  ( FIG. 15 ) that have been joined by glue or welding of the inside surface  62  (not shown) of the lower ring  63  (not shown) of the pump bottom  50  ( FIG. 8 ) and the outer surface  89  (not shown) of the upper ring  81  (not shown) of the bottle cap  80  ( FIG. 15 ). This air tight connection connects the air pump  162  (not shown), which fits above the pump bottom  50  and the container bottle  130  (not shown) which fits below the bottle cap  80 . 
   Still referring to  FIG. 13 .

   Referring now to  FIG. 14 .  FIG. 14  shows the container bottle  130  assembly as defined in  FIG. 1 . The container bottle  130  is constructed from the following parts: the bottle cap  80  ( FIG. 15 ), the container bottle  130  ( FIG. 16 ), the flexible bladder  140  ( FIG. 19 ), the tube  120  ( FIGS. 18 &amp; 24 ), the clip  150  ( FIG. 20 ), the discharge spout  90  ( FIG. 17 ), the flex disk  100  ( FIG. 21 ), and the keep  200  ( FIG. 22 ). 
   Still referring to  FIG. 14 . The bottle cap  80  is screwably attached to the container bottle  130  by the male threads  171  ( FIG. 16 ) of the container bottle  130  ( FIG. 16 ) screwed into the female threads  83  ( FIG. 15 ) of the bottle cap  80  ( FIG. 15 ) engaging the surface  84  of the bottle cap  80  ( FIG. 15 ) with the bottle top  172  of the container bottle  130  ( FIG. 16 ) which forms an air tight seal. 
   Still referring to  FIG. 14 . The discharge spouts  90  outer surface  91  ( FIG. 17 ) is slideably engaged with the hole  85  of the bottle cap  80  to the stop  86  ( FIG. 15 ) and the outer surface  91  ( FIG. 17 ) is glued or welded into the hole  85  ( FIG. 15 ) of the bottle cap  80  in an air tight connection. 
   Still referring to  FIG. 14 . The tubes  120  outer surface  121  (more clearly shown in  FIG. 18 ) is slideably engaged with the hole  87  ( FIG. 15 ) of the bottle cap  80  to the stop  88  ( FIG. 15 ) and the outer surface  121  ( FIG. 18 ) is glued or welded to the hole  87  ( FIG. 15 ) of the bottle cap  80  in an air tight connection. 
   Still referring to  FIG. 14 . The flexible bladder  140  is expanded and slid over the tube  120  until its inner sealing surface  141  ( FIG. 19 ) is opposite the sealing surface  123  ( FIG. 18 ) of the tube  120  and the two female recesses  142  of the flexible bladder  140  ( FIG. 19 ) are positioned over the two male seal ring  124  of the tube  120  ( FIG. 18 ). The inner surface  151  of the clip  150  ( FIG. 20 ) is positioned over the outer surface  143  of the flexible bladder  140  ( FIG. 19 ) between the two female recesses  142  of the flexible bladder  140  ( FIG. 19 ) and crimped in place with a crimping device, somewhat like a pair of pliers, (not shown) squeezing the clip  150  over the flexible bladder  140  ( FIG. 19 ) and sealing it to the tube  120  in an air tight manner. The gap  152  of the clip  150  ( FIG. 20 ) is reduced by this squeezing sealing compression action. 
   Referring now to  FIG. 15 .  FIG. 15  shows the outer surface of the upper ring  89 , the hole  87 , the hole  85 , the stop  86 , the upper ring  81 , the air passage slots  82 , the surface  84 , the female threads  83 , the web  93 , and the stop  88  of the bottle cap  80 . 
   Referring mow to  FIG. 16 .  FIG. 16  shows the bottle top  172 , and the male threads  171  of the container bottle  130 . 
   Referring now to  FIG. 17 .  FIG. 17  shows the outer surface  91 , and the inner ledge  92  of the discharge spout  90 . 
   Referring now to  FIG. 18 .  FIG. 18  is an expanded view of the top portion of the tube  120 . The viscous liquid  160  ( FIG. 3 ) that flows up and out of the container bottle  130  ( FIG. 3 ) is propelled through the tube  120  by the air pressure generated by the air pump  162  (see  FIGS. 3 ,  4 ,  5 , &amp;  6 ) squeezing the flexible bladder  140  ( FIGS. 3 &amp; 19 ) against the viscous liquid  160  ( FIG. 3 ). When almost all of the viscous liquid  160  ( FIG. 3 ) has been displaced by the flexible bladder  140  ( FIGS. 3 &amp; 19 ) the flexible bladder  140  ( FIGS. 3 &amp; 19 ) will eventually come to rest on the outer surface  125  of the ribs  126 . Some viscous liquid  160  ( FIG. 3 ) will be trapped in the annulus  127  between the ribs  126  and the outer surface  125  of the ribs  126  which is the flow path (not shown) of the very last part of the viscous liquid  160  (not shown see  FIG. 3 ) that came in the container bottle  130  ( FIG. 3 ). 
   Referring mow to  FIG. 19 .  FIG. 19  shows inner sealing surface  141 , the female recess  142 , the outer surface  143 , of the flexible bladder  140 . 
   Referring now to  FIG. 20 .  FIG. 20  shows the inner surface  151 , ant the gap  152  of the clip  150 . 
   Referring now to  FIG. 21 .  FIG. 21  shows the flex disk  100  in its up and “closed” position. The slots  103  that are arranged here in a “star” pattern are closed and liquid tight. The outer surface  101  of the flex disk  100  is slid up inside the discharge spout  90  ( FIG. 17 ) until its top ledge  102  comes in contact with the inner ledge  92  of the discharge spout  90  (not shown, see  FIG. 17 ). The retainer  200  ( FIG. 22 ) holds the flex disk  100  in place. 
   Still referring to  FIG. 21 . The flex disk  100 , known in the art, in its present configuration, prevents viscous liquids  160  ( FIG. 3 ) from “drooling” out the discharge spout  90  ( FIG. 17 ). 
   Referring now to  FIG. 22 .  FIG. 22  shows the retainer  200  that holds the flex disk  100  (not shown) to the discharge spout  90  (not shown). 
   Referring now to  FIG. 23 . When the viscous liquid  160  ( FIG. 3 ) is being pumped from the container bottle  130  ( FIG. 3 ) the flex disk  100  is flexing downward and the slots  103  are spread open ( FIGS. 3 &amp; 23 ) allowing the viscous liquid  160  ( FIG. 3 ) to pass through the flex disk  100  and exit the container bottle  130  ( FIG. 3 ). 
   Referring now to  FIG. 24 . This is an view of the lower portion of the tube  120  and flexible bladder  140  as the flexible bladder  140  has partially and almost completely collapsed around the tube  120  due to the air pressure generated by the air pump  162  (not shown) on the outside of the flexible bladder  140  forcing the viscous liquids  160  through the annulus of the ribs  127  ( FIG. 18 ) as the flexible bladder  140  comes to rest on the top of the ribs  125  ( FIG. 18 ) driving the viscous liquids  160  through a plurality of holes  201  and up the tube  120  as shown by arrows A.
