CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a Continuation in Part of U.S. application Ser. No. 12/877,502, filed Sep. 8, 2010 which claims the benefit of U.S. Provisional Application No. 61/249,335, filed Oct. 7, 2009, the disclosures of which are hereby incorporated by reference herein in their entireties all commonly owned.

FIELD OF THE INVENTION

The present invention is directed toward a system and method for filling balloons with a liquid. More specifically, the invention relates to a portable balloon filling station that allows users to easily fill balloons with liquid contained within the system.

BACKGROUND OF THE INVENTION

Filling balloons with liquid, typically water, for recreational purposes is a popular pastime activity, yet filling balloons with liquid is often cumbersome, messy, and sometimes painful.

A fixed water source such as a kitchen faucet or garden hose often has a relatively large opening that stretches the mouth of a water balloon beyond the breaking point. These sources also often suffer from sharp edges and threads that also promote balloon breakage.

Many devices exist that help to fill balloons with liquid by adapting a fixed water source into a balloon filling station. These sources suffer from additional limitations, such as not being portable and not providing water in a pressure range conducive to filling balloons. A high residential water pressure also leads to broken balloons, resulting in unwanted mess, wasted water, and the potential for injury when balloons break in a filler's hands.

These sources are also stationary, therefore necessitating multiple trips to the water source. This is often impracticable due to large distances between recreation sites and the fixed water source, resulting in long times spent away from the recreational site, a disincentive to engage in balloon-filling activities, and severely limiting the locations of recreational sites.

Accordingly, there is a need for a balloon filling device that is portable, safe, efficacious, and easy to use. Specifically, there is a need for a portable balloon filling system with a self-contained fluid reservoir that is capable of being pressurized, capable of repeatedly filling a balloon with fluid, yet does not promote balloon breakage.

SUMMARY OF THE INVENTION

In view of the foregoing background, it is therefore an object of the present invention to provide a balloon filling device, comprising a container capable of being pressurized by a fluid, wherein the container includes an opening, a filling head of a sufficient size and dimension to be secured to the opening of the container, a pump assembly attached proximate the filling head which extends into the opening of the container, a pump handle in communication with the pump assembly, a nozzle, having a first end and a second end, and having an internal conduit traversing from the first end to the second end that is in communication with the filling head, wherein the nozzle is sufficient to engage and maintain a balloon to be filled with the fluid, and a trigger mechanism in communication with the nozzle that controls the release of pressurized fluid from the container into the nozzle. The fill head is secured to the container with a screw thread.

The gasket is placed between the fill head and the container to prevent fluid leaks wherein the gasket material is selected from the group consisting of paper, rubber, silicone, compressed fiber, grease, metal, plastic, cork, felt, neoprene, nitrile rubber, polytetrafluoroethylene, and combinations thereof.

The nozzle includes at least one barb of a sufficient size and dimension to prevent a balloon from disengaging the barb while the balloon is being filled with fluid.

In addition, the device includes a pickup tube having one end that communicates with the nozzle and a second end that contacts liquid in the container. A screen is secured to the second end of the pickup tube to reduce clogging the pickup tube, trigger mechanism, and nozzle with foreign objects.

The pump assembly comprises a substantially rigid, substantially cylindrical tube having an inside surface, an outside surface, a substantially open first end, a second end, and a middle portion between the first and second ends, a pump shaft passing through the first end of the tube comprising a rigid rod having a first end, a second end, and a middle portion between the first and second ends, for reciprocating substantially within the confines of the tube, a piston secured to the first end of the pump shaft comprising a flexible ring that engages the inside surface of the tube forming a seal and defining an inner tube cavity, a pump handle secured to the second end of the pump shaft for gripping the pump shaft for manually reciprocating the pump shaft to expel air from the inner tube cavity, and a one way check valve communicating with the second end of the tube that allows air to be forced out of the inner tube cavity when the pump shaft plunges towards the second end of the tube, yet prevents air from returning into the tube cavity through the second end.

The balloon pump may, alternatively, comprise an electro-mechanical pump to pressurize the container.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout. Alternate embodiments of an element are notated with lowercase letters.

Overview of the Device

Referring initially to FIG. 1 and FIG. 2, in one embodiment of the invention, the two central components of the balloon pump 10, are a container 12 capable of being pressurized, and a filling head 14. The filling head 14 is capable of being sealedly secured to the container 12 so that the container, once pressurized, is able to maintain a pressurized state.

The container 12, is a vessel capable of attachment to the filling head 14. The preferred embodiment of attachment comprises a set of complimentary screw threads 16, 18 with a first set of threads 16 molded into the filling head 12, and the complimentary second set of threads 18 molded into the container 14. Additionally, a compliant o-ring or gasket 20 is situated between the container 12 and the filling head 14 to promote a fluid-tight seal at the filling head-container junction 22. The container 12 is made of a material chosen from the group consisting of high density polyethylene, low density polyethylene, polyethylene terephthalate, polyvinyl chloride, polypropylene, polystyrene, post-consumer resin, K-resin, epoxy resin, phenolic formaldehyde resin, stainless steel, aluminum, and any other material known in the art. The filling head 14 is made from a material chosen from the group consisting of high density polyethylene, low density polyethylene, polyethylene terephthalate, polyvinyl chloride, polypropylene, polystyrene, post-consumer resin, K-resin, epoxy resin, phenolic formaldehyde resin, stainless steel, aluminum, and any other material known in the art. The preferred materials for the container 12 are polymeric alloys suitable for blow molding, and the preferred material for the filling head 14 are polymeric alloys suitable for injection-molding. The gasket 20 material is selected from the group consisting of paper, rubber, silicone, compressed fiber, grease, metal, plastic, cork, felt, neoprene, nitrile rubber, polytetrafluoroethylene, and combinations thereof.

In one embodiment, a handle 24 is in communication with the filling head 14. The handle 24 may outwardly project from the filling head to promote the easy handling and gripping of the balloon pump 10. The handle comprises a series of undulatory recesses 25 that compliment gripping. However, with the handle 24 removed, as in FIG. 3, the balloon pump 10 is still easily gripped and handled, but through the gripping and handling of a handle-less filling head 14a instead of a handle 24.

FIG. 4 illustrates a hollow nozzle 26, having a tip 27 and a proximal end, is in communication with the filling head 14. In one embodiment, a hollow extension tube 28 is a boss, having a distal end and a proximal end, which projects from the filling head 14 and is in communication with the nozzle 26. The extension tube 28 may be molded into the filling head 14. Alternatively, the extension tube 28 may be fastened to the filling head 14 with pressure, threads, rivets, a twist-lock connector, or any other fastening means known in the art. In another embodiment, a hollow nozzle adapter 30, having a proximal end and a distal end, communicates with the extension tube 28 which in turn communicates with the nozzle 26. In this embodiment, the extension tube 28 comprises a first set of threads 32 on the distal end of the extension tube 28 that are complimentary with a second set of threads 34 situated on the proximal end of the nozzle adaptor 30.

The nozzle 26 serves two primary functions: first, to engage a balloon 36 to the balloon pump 10, and to provide a route for fluid to enter the balloon 36. The nozzle 26 comprises at least one barb of a sufficient size and dimension to prevent the balloon from disengaging the nozzle. In a preferred embodiment, the tip 27 of the nozzle is situated distally to the first barb, and the first barb 38 is situated distally to a second barb 40. The tip 27 is a sufficient size and shape to allow a balloon 36 to easily slide on the nozzle 26 without tearing. The tip 27 outwardly tapers, towards the proximal end of the nozzle 26, until reaching the first barb 38 which is the point where the taper diameter is greatest. The first barb 38 comprises a radiused apical ring 39 that inwardly tapers, towards the proximal end of the nozzle 26, the size and shape of which securely engages a balloon 36 yet does not comprise sharp edges that would otherwise promote the tearing of an engaged balloon 36. The second barb 40 comprises a radiused apical ring 41 that inwardly tapers, towards the proximal end of the nozzle 26, the size and shape of which securely engages a balloon 36 yet does not comprise sharp edges that would otherwise promote the tearing of an engaged balloon 36. The radius of the second barb 40 is larger than the first barb 38 so that a majority of commercially available water balloons will securely engage the nozzle 26 using at least one of the first barb 38 and second barb 40. Proximal to the second barb 40, the nozzle 26 comprises a radiused ringed ridge 42 that forms a channel 44 (FIG. 5) where the nozzle 26 abuts the nozzle adaptor 30. The channel 44 aids in securely engaging a balloon 36 to the nozzle 26. The nozzle 26 comprises an internal conduit 46 traversing from the tip 27 to the proximal end of the nozzle 26. Fluid passes through the nozzle 26, entering the conduit 46 at the proximal end of the nozzle 26, and exiting the tip 27 to enter the balloon 36. The nozzle 26 also comprises at least one raised ridge 43 that aids in securing the nozzle 26 to the nozzle adaptor 30 by engaging at least one complimentary channel 45 in the nozzle adaptor 30.

In one embodiment exemplified by FIG. 5, the hollow extension tube 28 houses a valve 48 that controls the release of fluid from the container 12 into the balloon 36. The valve 48 is a shaft having a seating end 50 and an engaging end 52 connected by a center section of the shaft. Proximate the seating end is a flange 54 upon which a spring 56 makes pressured contact. The spring 56, which is laterally bound within the hollow extension tube 28, has a first end and second end. The first end of the spring 56 seats against the filling head 14, and the second end of the spring 56 seating against the flange 54. A valve seat 58 engages the seating end 50 of the valve 48. The valve seat 58 is a cylindrical disc that comprises a hole that communicates between the conduit 46 of the nozzle 26 and the interior cavity of the hollow extension tube 28. The valve seat 58 engages a distal lip 60 of the extension tube 28 thereby capturing the valve seat 58, valve 48, and spring 56 within the extension tube 28. The size and dimension of the spring 56 is such that the valve 48 is under spring tension, forcibly pressing against the hole in the valve seat 58, when the valve seat 58, valve 48, and spring 56 are installed within the extension tube 28. A trigger 62 communicates with the filling head 14 that also communicates with the engaging end 52 of the valve 48. When the trigger 62 is actuated, the spring tension is overcome, and the seating end 50 of the valve 48 unseats from the valve seat 58. If pressurized fluid is present in the hollow cavity of the extension tube 28, it exits the balloon pump 10 by flowing from the container 12 into the hollow extension tube 28, through the hole in the valve seat 58, through the nozzle 26, entering the conduit 46 at the proximal end of the nozzle 26, and exiting the tip 27 to enter a balloon 36 engaged to the nozzle 26.

FIG. 6 and FIG. 7 illustrate an embodiment of the filling head 14 that comprises a pumping mechanism that is manually pumped to pressurize the container 12. The pump assembly comprises a substantially rigid, substantially cylindrical pump tube 64 having an inside surface, an outside surface, a substantially open proximal end, a distal end, and a middle portion between the proximal and distal ends. The pump tube 64 attaches to the filling head 14. In one embodiment illustrated in FIG. 5, the pump tube 64 comprises a first set of threads 70 on the proximal end of the pump tube 64 that are complimentary with a second set of threads 72 situated on the filling head 14. The pump tube 64 is made from a material chosen from the group consisting of high density polyethylene, low density polyethylene, polyethylene terephthalate, polyvinyl chloride, polypropylene, polystyrene, post-consumer resin, K-resin, epoxy resin, phenolic formaldehyde resin, stainless steel, aluminum, and any other material known in the art. The preferred materials for the tube 64 are polymeric alloys suitable for injection-molding.

A pump shaft 66, comprising a rigid rod having a first end, a second end, and a middle portion between the first and second ends, that passes through a pump channel 68 in the filling head 14 and into the pump tube 64 through the proximal end of the pump tube 64. The pump shaft 66 is made from metal or a hard polymer. A pump handle 74 attaches to the first end 76 of the pump shaft 66. A piston assembly 78 is secured to the second end 80 of the pump shaft 66. The piston assembly 78 comprises a flexible ring 82 that engages the inside surface of the tube forming a movable seal and defining an inner tube cavity 84. The pump handle 74 aids in gripping the pump shaft 66 for the purpose of manually reciprocating the pump shaft 66 to expel air from the inner tube cavity 84 into the container 12. Alternate embodiments of the pump handle 74a, 74b are illustrated in FIG. 8 and FIG. 9 respectively.

A one way check valve 86 communicates with the distal end of the pump tube 64 that allows air to be forced out of the inner tube cavity 84 when the pump shaft 66 plunges towards the distal end of the tube, yet prevents air from returning into the tube cavity through the distal end of the pump tube 64. The check valve 84 comprises a compliant flap that abuts a sealing lip 88 proximate the distal end of the pump tube 64. The sealing lip 88 engages the edge of the check valve 86 when the pressure inside the container 12 is greater than or equal to the pressure in the inner tube cavity 84 therefore preventing fluid back flow into the inner tube cavity 84.

When the pump shaft 66 is manually reciprocated, air in the inner tube cavity 84 is expelled during a pumping down-stroke (when the pump handle 74 is travelling towards the filling head 14) causing air in the inner tube cavity 84 to break the seal between the sealing lip 88 and the edge of the check valve 86 and to travel into the container 12, causing an increase in the container pressure. When the pump shaft 66 is manually reciprocated during a pumping up-stroke (when the pump handle 74 is travelling away from the filling head 14), the sealing lip 88 and the edge of the check valve 86 sealedly engages to prevent fluid from the container 12 from entering the inner tube cavity 84, so air travels from without the balloon pump 10, through the pump channel 68, into the proximal end of the pump tube 64, and into the inner tube cavity 84.

A pickup tube 90, having a proximal and distal end, is attached to the filling head 14 at the proximal end of the pickup tube 90. The interior of the pickup tube 90 communicates with a duct 92 in the filling head that communicates with the hollow interior cavity of the extension tube 28. The distal end of the pickup tube 90 is attached to a screen 94 that prevents debris from entering the pickup tube 90. The pickup tube 90 is made from a material chosen from the group consisting of high density polyethylene, low density polyethylene, polyethylene terephthalate, polyvinyl chloride, polypropylene, polystyrene, post-consumer resin, K-resin, epoxy resin, phenolic formaldehyde resin, stainless steel, aluminum, and any other material known in the art. The screen 94 is made from a material chosen from the group consisting of high density polyethylene, low density polyethylene, polyethylene terephthalate, polyvinyl chloride, polypropylene, polystyrene, post-consumer resin, K-resin, epoxy resin, phenolic formaldehyde resin, stainless steel, aluminum, brass, and any other material known in the art. Pressurized fluid in the container 12 is forced past the screen 94, into the pickup tube 90, and travels through the duct 92 and into the hollow interior cavity of the extension tube 28.

In one embodiment, the manual pump assembly is replaced by an electromechanical pump. In this embodiment, a switch communicating with the electromechanical pump actuates the electromechanical pump to pressurize the container 12.

Overview of the Method

FIG. 10 exemplifies a method of filling a balloon 36 with fluid. The method comprising the steps of placing a fluid into a container 12 through an opening in the container, and securing a filling head 14 to the container. A user then pumps a pump assembly FIG. 10 and FIG. 11, wherein the pump assembly is attached proximate the filling head 14, extending into the opening of the container to pressurize the container 12.

In order to fill a balloon with fluid, a user engages a balloon 36 onto a nozzle 26. FIG. 12 illustrates a user actuating a trigger mechanism 62 to relieve the pressure of the container, thereby forcibly evacuating the container 12 of fluid and filling the balloon 36 with liquid. In particular, pressure is increased in the container 12 as a result of repeated pumping of air into the container 12. Pressurized fluid in the container 12 is forced past the screen 94, into the pickup tube 90, and travels through the duct 92 and into the hollow interior cavity of the extension tube 28. Pressurized fluid present in the hollow cavity of the extension tube 28 exits the balloon pump 10 by flowing from the container 12 into the hollow extension tube 28, through the hole in the valve seat 58, through the nozzle 26, entering the conduit 46 at the proximal end of the nozzle 26, and exiting the tip 27 of the nozzle 26 to enter a balloon 36 engaging the nozzle 26. In a preferred embodiment, the fluid entering the balloon 36 is at least one of air and water.
