Description

BACKGROUND

The present invention relates generally to refilling a fluid dispenser bottle, and more particularly to adapters, systems, and methods that can be used to refill a dispenser bottle.
There are a wide variety of fluids that are dispensed from dispenser bottles. Such fluids include edible fluids such as ketchup, mustard, barbeque sauce, mayonnaise, etc., as well as a many other fluids. These other fluids include both viscous and non-viscous fluids. Exemplary viscous fluids include ultrasound gels used to ultrasonically couple ultrasound transducers (e.g., an imaging transducer, a therapeutic transducer) with a patient.
Existing dispenser bottles include dispenser bottles configured to be hand held. Such a hand-held dispenser bottle is often flexible so that the fluid can be dispensed by squeezing the bottle to discharge the fluid through a dispenser nozzle. The amount of fluid held in such a dispenser bottle may be, however, relatively modest given weight and size constraints consistent with ease of use. As a result, a large number of such dispenser bottles, following dispensing of the fluid there from, become emptied of the fluid to a point that inhibits further effective dispensing of the fluid without refilling of the dispenser bottle.
Unfortunately, existing approaches used to refill dispenser bottles may be less than desirable due to being time consuming, messy, expensive, and/or inconvenient. For example, some ultrasound gels are relatively viscous and can be somewhat sticky, thereby making it a more difficult and time consuming effort to refill a dispenser bottle with such an ultrasound gel. In many applications, such as medical applications employing ultrasound gels, the expense associated with refilling a dispenser bottle is greater due to the high cost of the personnel involved. As a result, it may be more economical to just discard the dispenser bottle once it becomes depleted rather than incur the expense associated with refilling the dispenser bottle. Such an approach, however, results in a good deal of wasted material (e.g., the dispenser bottle, any residual fluid in the dispenser bottle) as well as associated disposal issues and expense.
Accordingly, improved approaches for refilling dispenser bottles are desirable. Such improved approaches should provide for convenient and economical refilling of dispenser bottles, especially where viscous and possible sticky fluids such as some ultrasound gels are involved.

BRIEF SUMMARY

The following presents a simplified summary of some embodiments of the invention in order to provide a basic understanding of the invention. This summary is not an extensive overview of the invention. It is not intended to identify key/critical elements of the invention or to delineate the scope of the invention. Its sole purpose is to present some embodiments of the invention in a simplified form as a prelude to the more detailed description that is presented later.
Adapters, systems, and methods are provided that can be used to refill a dispenser bottle. The disclosed adapters, systems, and methods provide for convenient and economical refilling of dispenser bottles, and can be particularly beneficial when used in conjunction with refilling dispenser bottles used to dispense a viscous and/or somewhat sticky fluid, such as an ultrasound coupling gel. While embodiments of the adapters, systems, and methods disclosed herein are described primarily in conjunction with ultrasound coupling gels, such adapters, systems, and methods can be used in conjunction with any suitable fluid, both edible and non-edible.
Thus, in one aspect, an adapter is provided for connecting a fluid package to a dispenser bottle. The adapter includes a duct, a fluid package coupler, a dispenser bottle coupler, and at least one orifice. The duct is configured to convey a fluid being transferred from the fluid package to the dispenser bottle. The fluid package coupler is coupled with the duct and configured to couple with the fluid package so as to place the duct in fluid communication with the fluid package. The dispenser bottle coupler is coupled with the duct and configured to couple with the dispenser bottle so as to place the duct in fluid communication with the dispenser bottle. And the at least one orifice is disposed offset from the duct. The at least one orifice vents the dispenser bottle when fluid is transferred from the fluid package to the dispenser bottle.
In many embodiments, the duct is configured to discharge the transferred fluid into the dispenser bottle so that the discharged fluid does not inhibit the venting of the dispenser bottle through the at least one orifice. For example, the duct can be configured to discharge fluid transferred from the fluid package to the dispenser bottle offset from the at least one orifice. The duct can extend beyond both ends of the at least one orifice. And the duct can extend into the dispenser bottle when the dispenser bottle coupler is coupled with the dispenser bottle. The duct can have a discharge cross section from which fluid transferred from the fluid package to the dispenser bottle is discharged, the discharge cross section having an area less than an area of a receiving cross section of the dispenser bottle across which the discharge fluid passes.
In many embodiments, the adapter includes one or more threaded interfaces. For example, the fluid package coupler can include a threaded interface configured to couple with a complimentarily configured threaded interface of the fluid package. And the fluid package coupler can include a female coupler configured to couple with a male coupler of the fluid package. The dispenser bottle coupler can include a threaded interface configured to couple with a complementarily configured threaded interface of the dispenser bottle. And the dispenser bottle coupler can include a female coupler configured to couple with a male coupler of the dispenser bottle.
In many embodiments, the adapter includes multiple orifices, which are used to vent the dispenser bottle during refilling. For example, the adapter can include a plurality of orifices, each of the orifices being disposed offset from the duct. In many embodiments, the adapter includes four orifices. And in many embodiments, the orifices are uniformly distributed around the duct.
The adapter can include a fluid control valve that can be used to control fluid flow between the fluid package and the dispenser bottle. For example, the adapter can include a one-way valve configured to inhibit fluid flow from the dispenser bottle to the fluid package. The adapter can include a valve operable to control flow of the fluid through the duct. And the adapter can include a rotary valve operable to control flow of the fluid through the duct.
In another aspect, a system is provided for refilling a dispenser bottle with a fluid. The system includes a reservoir for storing a quantity of the fluid and an adapter configured to couple the reservoir with the dispenser bottle. The adapter includes a duct, a reservoir coupler, a dispenser bottle coupler, and at least one orifice. The duct is configured to convey a quantity of the fluid being transferred from the reservoir to the dispenser bottle. The reservoir coupler is coupled with the duct and is configured to couple with the reservoir so as to place the duct in fluid communication with the reservoir. The dispenser bottle coupler is coupled with the duct and is configured to couple with the dispenser bottle so as to place the duct in fluid communication with the dispenser bottle. And the at least one orifice is disposed offset from the duct. The at least one orifice vents the dispenser bottle when the quantity of the fluid is transferred from the reservoir into the dispenser bottle. The system can include a valve operable to control flow of the fluid through the duct. And the system can include a rotary valve operable to control flow of the fluid through the duct.
In many embodiments, the reservoir is flexible so that it can be deformed using hand pressure to increase pressure within the reservoir to promote transfer of fluid from the reservoir to the dispenser bottle. The reservoir can include a plurality of impermeable membrane panels that are bonded together to form a flexible fluid retaining body. The membrane panels can include, for example, two or more bottom panels that form a gusseted base configured so that the reservoir will remain in an upright orientation when placed on a horizontal support surface.
The reservoir can include other suitable features. For example, the reservoir can include an inlet/outlet port configured to couple with the reservoir coupler so as to place the reservoir in fluid communication with the duct. The reservoir can include at least one hanging feature, such as at least one hanging opening that is configured to receive a support member so that the reservoir can be suspended in an inverted orientation in which the inlet/outlet port is oriented to discharge fluid downward into the dispenser bottle. And the reservoir can include a carrying handle, such as a carrying handle opening disposed in an area having a top panel of the reservoir bonded to a side panel of the reservoir.
In another aspect, a method is provided for refilling a dispenser bottle with a fluid. The method includes coupling an adapter fitting to the dispenser bottle; coupling the adapter fitting to a reservoir containing the fluid; transferring a quantity of the fluid from the reservoir, through the adapter fitting, and into the dispenser bottle; and venting the dispenser bottle via at least one orifice in the adapter fitting during the transfer of the quantity of the fluid into the dispenser bottle.
The method can further include acts used to promote the transfer of the fluid from the reservoir to the dispenser bottle. For example, the method can include deforming the reservoir so as to increase pressure in the reservoir to promote the transfer of the quantity of the fluid into the dispenser bottle. The method can include orienting the reservoir in an inverted orientation and orienting the dispenser bottle in an upright orientation so that the quantity of the fluid is transferred in a downward direction from the reservoir into the dispenser bottle. And the method can include hanging the reservoir in the inverted orientation.
In another aspect, a method is provided for refilling a dispenser bottle with a viscous fluid. The method includes providing a flexible reservoir containing the viscous fluid, the flexible reservoir formed from a plurality of flexible membrane panels including two or more bottom panels that form a gusseted base configured to support the flexible reservoir in an upright orientation when placed on a horizontal support surface; placing the flexible reservoir in an inverted orientation, wherein the viscous fluid does not flow out of the flexible reservoir through an open orifice in the flexible reservoir; and deforming the flexible reservoir so as to increase pressure in the flexible reservoir to eject a quantity of the viscous fluid through the open orifice into the dispenser bottle.
For a fuller understanding of the nature and advantages of the present invention, reference should be made to the ensuing detailed description and accompanying drawings.

DETAILED DESCRIPTION

In the following description, various embodiments of the present invention will be described. For purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the embodiments. However, it will also be apparent to one skilled in the art that the present invention can be practiced without the specific details. Furthermore, well-known features may be omitted or simplified in order not to obscure the embodiment being described.
Referring now to the drawings, in which like reference numerals represent like parts throughout the several views, FIG. 1 shows a system 10 for refilling a dispenser bottle 12, in accordance with many embodiments. The system 10 includes a fluid package 14 that can be suspended in an inverted orientation as illustrated in FIG. 1, and an adapter fitting 16 that is used to couple the fluid package 14 with the dispenser bottle 12.
The fluid package 14 includes a flexible reservoir 18, an inlet/outlet port 20, a carrying handle opening 22, and two hanging openings 24. The flexible reservoir 18 is formed from a plurality of impermeable membrane panels that are bonded together along perimeter portions of the panels. The impermeable membrane panels include two bottom panels 26 that form a base to support the fluid package in an upright orientation when the fluid package is placed on a horizontal support surface. Each of the two bottom panels 26 is bonded into both a side panel of the flexible reservoir 18 and to the other bottom panel, thereby forming a base that includes two bonded strips between the bottom panels 26 and a respective side panel of the flexible reservoir 18 and a bonded strip between the two bottom panels 26. These three bonded strips provide a stable gusseted base that supports the fluid package 14 in the upright orientation when the fluid package 14 is placed on a horizontal support surface. The two hanging openings 24 are disposed at the bottom of the fluid package in a perimeter portion of the bottom panel 26, which is bonded to a perimeter portion of a side panel of the flexible reservoir 18. While two bottom panels 26 are shown forming the gusseted base, more than two bottom panels can also be used to form a stable gusseted base, thereby providing additional bonded strips.
The inlet/outlet port 20 is disposed at the top of the flexible reservoir 18 adjacent to the carrying handle opening 22. The top of the flexible reservoir 18 can include a top panel that is bonded to side panels of the flexible reservoir 18 along perimeter portions of the top and side panels. The inlet/outlet port 20 can be bonded into the flexible reservoir 18. For example, a length of the top panel perimeter portion can be bonded around a perimeter portion of the inlet/outlet port 20 and a length of a side panel perimeter portion can be bonded around the remaining perimeter portion of the inlet/outlet port 20. The inlet/outlet port 20 provides a fluid path through which the flexible reservoir 18 can be filled with fluid and through which fluid can be transferred from the flexible reservoir 18 to refill the dispenser bottle 12. The carrying handle opening can be disposed in a perimeter portion of a side panel. And for added strength, the carrying handle opening can be disposed in an area where a perimeter portion of the side panel is bonded to a perimeter portion of the top panel.
While the fluid package 14 is described as having the flexible reservoir 18, any suitable type of reservoir can be used. For example, a suitable non-flexible reservoir can be used. When a non-flexible reservoir is used, a means for increasing pressure within the non-flexible reservoir can be used to promote transfer of fluid from the non-flexible reservoir to the dispenser bottle 12 during the refilling of the dispenser bottle 12.
In FIG. 1, the fluid package 14 is shown in an inverted orientation that can be used to promote transfer of fluid from the flexible reservoir 18 into the dispenser bottle 12. The fluid package 14 is suspended in the inverted orientation from support members 28 that engage the hanging openings 24. The dispenser bottle 12 is suspended from the adapter fitting 16, which is suspended from the fluid package 14.
FIG. 2 illustrates an exploded perspective view of components of the system 10. An inlet/outlet port cap 30 can be coupled with the inlet/outlet port 20 to prevent fluid from escaping the fluid package 14 when the fluid package 14 is not being used to refill the dispenser bottle 12. The inlet/outlet port cap 30 can have an internal thread configured to interface with a complementarily configured external thread of the inlet/outlet port 20. The adapter fitting 16 includes a fluid package coupler 32 that is configured similar to the inlet/outlet port cap 30 so that the fluid package coupler 32 can be attached to the inlet/outlet port 20.
The adapter fitting 16 includes a dispenser bottle coupler 34. The dispenser bottle coupler 34 is configured to couple to the dispenser bottle 12. For example, the dispenser bottle coupler 34 can have an internal thread configured to interface with a complementarily configured external threaded portion of the dispenser bottle 12.
The system 10 can optionally include a valve 35 that is operable to control flow of the fluid from the fluid package 14. The valve 35 can be incorporated in any suitable way. For example, the valve 35 can be added in-line between the inlet/outlet port 20 and the adapter fitting 16 by coupling one end of the valve 35 to the inlet/outlet port 20 and the other end of the valve 35 to the adapter fitting 16. As another example, the valve 35 can be an integral part of the adapter fitting 16. Any suitable type of valve can be used as the valve 35. For example, the valve 35 can be a rotary valve, for example, a ball valve. Inclusion of the valve 35 may be especially beneficial where the fluid in the fluid package 14 is substantially non-viscous.
FIG. 3 shows a perspective view of the adapter fitting 16. The adapter fitting 16 includes four orifices 36 (three shown and one hidden from view), which vent the dispenser bottle 12 when fluid is transferred from the fluid package 14 to the dispenser bottle 12. The orifices 36 place the inside of the dispenser bottle 12 in fluid communication with the atmosphere, thereby providing a venting path for the discharge of air from the dispenser bottle 12 during the refilling of the dispenser bottle 12.
FIG. 4 shows a cross-sectional view of another adapter fitting 38, in accordance with many embodiments. The adapter fitting 38 includes a fluid package coupler 40, a duct 42 attached to the fluid package coupler 40, a dispenser bottle coupler 44, and a partition 46 that attaches the dispenser bottle coupler 44 to the duct 42. The partition 46 has multiple orifices 48 distributed around the duct 42.
The fluid package coupler 40 has internal threads configured to interface with complimentarily configured external threads of the fluid package. When the fluid package coupler 40 is coupled to the input/output port 20, the duct 42 is placed in fluid communication with the fluid reservoir of the fluid package. While a threaded interface is shown, any other suitable known coupling interface can be used to couple the adapter fitting 38 to the input/output port 20.
The duct 42 extends beyond both ends of the orifices 48. A discharge cross section 50 of the duct 42 is offset from the orifices 48, which may help to keep the fluid being transferred away from the orifices 48 and thereby avoid plugging the orifices 48 or escaping through the orifices 48. The discharge cross section 50 has a cross-sectional area that is less than an area of a receiving cross section of the dispenser bottle across which fluid discharged from the duct 42 passes. The discharge cross section 50 is also offset laterally from the orifices, which also serves to keep the fluid that is discharged from the duct from plugging the orifices and/or escaping from the orifices.
The extended duct 42 includes external male threads that match the external male threads of the input/output port 20 so that the inlet/outlet port cap 30 can be coupled with the extended duct 42. Such a configuration allows the adapter fitting 38 to remain attached to the fluid package 14 while also preventing fluid from escaping the fluid package 14 when the fluid package 14 is not being used to refill the dispenser bottle 12. While a threaded interface is shown, any other suitable known coupling interface can be used to couple the inlet/outlet port cap 30 to the extended duct 42.
FIG. 5 shows a cross-sectional view of another adapter fitting 52, in accordance with many embodiments. The adapter fitting 52 is configured similar to the adapter fitting 38, but has a duct 54 that, while not extending beyond both ends of the orifices 48 as in the adapter fitting 38, is offset from the orifices 48 and has a discharge cross section 56 that has a cross-sectional area that is less than an area of a receiving cross section of the dispenser bottle 12 across which fluid discharged from the duct 54 passes.
The inlet/outlet port 20 and/or the duct 42, 54 can be configured based on the viscosity of the fluid in the fluid package 14 so that the fluid does not flow out of the fluid package 14 without an increase in internal pressure within the fluid package 14. For example, such an increase in pressure can be selectively caused by squeezing or otherwise deforming the fluid package 14 to force the fluid out through the inlet/outlet port and/or the duct 42, 54. With such a configuration, the dispenser bottle need not be coupled to the fluid package 14, but can be held underneath and the fluid selectively squirted into the dispenser bottle by selectively deforming the fluid package 14. Other means of increasing pressure within the fluid package can also be used, such as injecting pressurized air into the fluid package 14.
FIG. 6 shows a cross-sectional view of another adapter fitting 58, in accordance with many embodiments. The adapter fitting 58 is configured similar to the adapter fitting 52 of FIG. 5, but includes a one-way valve 60 that inhibits flow of the fluid from the dispenser bottle 12 into the reservoir 18.
FIG. 7 illustrates venting of the dispenser bottle 12 during refilling of the dispenser bottle 12, in accordance with many embodiments. With the fluid package 24 in the inverted orientation and the dispenser bottle 12 attached to the fluid package 14 via the adapter fitting 16, the reservoir 18 is deformed (e.g., using hand pressure), thereby forcing fluid from the reservoir 18 through the adapter fitting 16 into the dispenser bottle 12. The fluid is discharged from the adapter fitting duct into the dispenser bottle 12 at the discharge cross section of the duct. Because the discharge cross section of the duct has a cross sectional area that is less than the area of the receiving cross section of the dispenser bottle, air in the dispenser bottle that is displaced by the incoming fluid has a pathway to reach the orifices and be vented there from. The configuration of the adapter fitting provides for continuous venting of the displaced air in the dispenser bottle during refilling of the dispenser bottle.
FIG. 8 lists acts of a method 70 for refilling a dispenser bottle with a fluid, in accordance with many embodiments. The method 70 includes coupling an adapter fitting to the dispenser bottle (act 72); coupling the adapter fitting to a reservoir containing the fluid (act 74); transferring a quantity of the fluid from the reservoir, through the adapter, and into the dispenser bottle (act 76); and venting the dispenser bottle via at least one orifice in the adapter fitting during the transfer of the quantity of the fluid into the dispenser bottle (act 78).
FIG. 9 lists additional acts that can be used in the method 70 of FIG. 8, in accordance with many embodiments. As optional acts, the method 70 can also include deforming the reservoir so as to increase pressure in the reservoir to promote the transfer of the quantity of the fluid into the dispenser bottle (act 80); orienting the reservoir in an inverted orientation and orienting the dispenser bottle in an upright orientation so that the quantity of the fluid is transferred in a downward direction from the reservoir into the dispenser bottle (act 82); and hanging the reservoir in the inverted orientation (act 84).
The method 70 can be practiced using any suitable reservoir, adapter fitting, and dispenser bottle. For example, the method 70 can be practiced using the reservoirs, adapter fittings, and dispenser bottles described herein.
FIG. 10 lists acts of a method 90 for refilling a dispenser bottle with a viscous fluid, in accordance with many embodiments. The method 90 includes providing a flexible reservoir containing the viscous fluid, the flexible reservoir formed from a plurality of flexible membrane panels including two or more bottom panels that form a gusseted base configured to support the flexible reservoir in an upright orientation when placed on a horizontal support surface (act 92); placing the flexible reservoir in an inverted orientation, wherein the viscous fluid does not flow out of the flexible reservoir through an open orifice in the flexible reservoir (act 94); and deforming the flexible reservoir so as to increase pressure in the flexible reservoir to eject a quantity of the viscous fluid through the open orifice into the dispenser bottle (act 96). Act 94 can be accomplished by, for example, hanging the flexible reservoir in the inverted orientation.
The method 90 can be practiced using any suitable reservoir and dispenser bottle. For example, the method 90 can be practiced using the reservoirs and dispenser bottles described herein. And method 90 can also be practiced using the adapter fittings described herein.
