CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a Continuation-in-Part Application of, under 35 U.S.C. §121, and claims priority to, under 35 U.S.C. §121, U.S. Non-Provisional application Ser. No. 11/278,776, entitled Spray Bottle System, by C. Justin McFarland, filed on Apr. 5, 2006.

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to spray bottle assemblies, more specifically a spray bottle assembly that maintains a constant access of fluid to the spray pump.
2. Description of the Related Art
In the related art, it has been known to use devices for spraying various liquids. Spray devices have been developed for applying cleaning products, pesticides, and aromatics to name a few. Such spray devices have allowed for convenience and portable spraying of many surfaces but have previously been limited in the direction and scope of their ability to spray surfaces from any direction without interruption. Certain spray devices containing an inner reservoir incorporate holes in the outer bottle exposing the inner reservoir to accidental or intentional tampering thus compromising the integrity of the spray device. Further, contemporary spray devices have been unable to discharge completely the various products they contain. Therefore there is a need to effectively spray apply solutions to difficult to reach surfaces without interruption of liquid flow from the spray device, enabling the contents of the spray device to be discharged completely, as well as to provide a tamperproof inner reservoir version of the same.
The inventions referenced have numerous disadvantages including unreliability, limited spray direction and scope, sporadically interrupted spray flow, exposure to tampering, and inability to use the entire contents of the spray bottle.
What is needed is a spray bottle assembly that overcomes one or more of the deficiencies described herein and/or any additional deficiencies that may be realized by someone who is skilled in the art as they become familiar with this specification.

FIGS. 1 and 2 illustrate a spray bottle system 100 capable of discharging substantially all of the liquid contents, is refillable, and can operate over all spray angles of typical interest.
A molded spray bottle container (or protective outer enclosure) 102 provides housing and protection for a refillable content bladder (or inner collapsible reservoir) 114. In one embodiment of the invention, the spray bottle container 102 includes threads 106 located on its neck. The liquid content bladder 114 contains a seal 118 used to seal the bladder 114 with the bottle neck 106. The seal 118 contains threads 122 for mating with the threaded collar 138 of a spray head 134.
As more liquid is displaced, the bladder 114 contracts around the suction tube (or conduit) 126 until almost all the liquid contents have been expelled. To eliminate the inherent vacuum that would form between the bladder and the inside wall of the spray bottle, several air ports 110 are formed or drilled through the wall of the spray bottle. The purpose of the air portals is to equalize the air pressure on both sides of the spray bottle wall, and thus eliminate an internal vacuum.
To allow the spray bottle system to operate at a myriad of tilt angles, the suction tube 126 contains several tube holes 130 along its length. This allows the bladder liquid to enter the suction tube at various locations, and not be limited to the tube end. The tube holes 130 are believed to facilitate capillary action to help remove all of the liquid from the bladder, regardless of the bottle tilt angle.
In one embodiment of the invention, the bladder 114 contains a refilling port 154, which can be exposed to the outside through a refilling port opening 152. As a matter of design choice, the refilling port and the refilling port opening can be affixed, although this need not be the case. The refilling port 154 can also be as simple as a one way valve. In such a case, a rigid or semi-rigid refilling tube can be inserted into the bladder via the refilling port. The refilling tube can be connected to a refill bulb or refill bladder, which when squeezed, forces liquid content into the liquid content bladder 114.
The bladder 114 need not be attached to the spray bottle container in the manner described above. In fact, it may be sealed to the bottle neck during manufacturing. Also, other mechanisms beside the specific seal (118) embodiment can be used.
In one embodiment of the invention of the spray bottle system is illustrated in FIG. 2. The system 200 is the same as the system 100, except that a simple bladder seal 218 replaces the seal 118 and threads 122. In this simpler version, the bladder seal 218 fits on the top of the bottle neck 106 and is mated directly to the spray head 134 by screwing the spray head onto the bottle neck to provide a vacuum seal. The bladder seal can be of any suitable material, but is preferably non-rigid, such as rubber, flexible plastic, and the like to provide a suitable seal.
FIGS. 3 and 4 illustrate a vented retaining ring 30 having a flat solid top edge 32 and an interior cylindrical wall 34 configured to be fluid impermeable from the top edge of the interior wall 36 to the bottom edge of the interior wall 38. The vented retaining ring 30 includes an outer cylindrical wall 40 having a series of radial slots (or channels) 42 extending through a portion of the outer wall 40 and also through a portion of the bottom edge of the interior wall 38. The radial slots 42 are configured to form vents when assembled and is positioned adjacent to a protective outer enclosure. The slots 42 are adjacent a support member configured to structurally support the channel and a sealing member shaped and positioned to provide a fluid tight seal between the bladder and the spray head.
FIG. 5 illustrates a spray bottle assembly, according to one embodiment of the invention. The spray bottle assembly 10 includes an integrally assembled vented retaining ring 30 and an inner collapsible reservoir 50 within a protective outer enclosure 52. As shown in FIG. 5, the spray bottle assembly 10 forms a double walled reservoir and is sealed to and combined with a trigger pump 54 having a shroud 56 that covers the vented retaining ring 30 without substantially restricting fluid, or air, communication there through. The shroud 56 covers the vented retaining ring 30 thereby closing off the inner collapsible reservoir 50 from being compromised by intentional tampering or accidental puncturing through a slot 42 of the retaining ring 30. The slots 42 of the retaining ring 30 are sized to permit fluid communication there through, between the interior and exterior of the protective outer enclosure 52; thus preventing a vacuum between the exterior of the inner collapsible reservoir 50 and an interior of the protective outer enclosure 52, and allowing the general extended use of the spray bottle assembly 10. The inner collapsible reservoir 50 is sealed to the trigger pump 54 preventing air from entering into the interior of the collapsible reservoir 50.
FIG. 5 illustrated a spray bottle assembly, according to one embodiment of the invention. The spray bottle assembly 10 includes an inner reservoir 50 that collapses around a cylindrical screened conduit 60 as the fluid contents of the inner collapsible reservoir 50 are discharged through the trigger pump 54. As the inner reservoir 50 collapses around the cylindrical screened conduit 60, fluid is forced into contact with the conduit 60 making the fluid available to the trigger pump 54 at all times and in any orientation of the spray bottle assembly 10. The rigid cylindrical screened conduit 60 maintains an inner open conduit area within the inner collapsible reservoir 50 from the top of the assembly 58 to the bottom of the assembly 59.
FIG. 6 illustrates a partial cross-sectional view of an assembly of the vented retaining ring 30 adjacent to the opening of the protective outer enclosure 52 and the inner collapsible reservoir 50, according to one embodiment of the invention. The inner collapsible reservoir 50 is not selectably removable from the vented retaining ring 30. A slot 42 on the underside of the retaining ring 30 permits fluid, or air, communication between an interior wall 66 and an exterior wall 62 of the protective outer enclosure 52.
FIG. 7 illustrates an assembly of the vented retaining ring 30 and the inner collapsible reservoir 50, according to one embodiment of the invention. The collapsible reservoir is not selectably removable from the vented retaining ring 30.
FIG. 8 illustrates a conduit, according to one embodiment of the invention. The conduit 60 is composed of a rigid outer cylindrical screen 38 having a lattice of apertures 70 which allow fluid within an inner collapsible reservoir to freely pass through into an interior of the conduit 60 maintaining a constant availability of fluid to a trigger pump of the spray bottle assembly.
