DETAILED DESCRIPTION The present disclosure is directed to an apparatus and method for facilitating the washing of containers, such as those used in the laboratory setting. In general, the apparatus of the present disclosure is directed to a series of interconnected conduits and fluid delivery members for transferring a fluid to a nozzle, whereby the fluid may be dispersed from the nozzle to facilitate washing of an interior space of a container. The apparatus may comprise one or more valves to regulate fluid flow throughout the apparatus. The apparatus may also be part of a system which comprises one or more of timers, sensors, pumps, a control module, and/or a computer. The apparatus of the present disclosure may thus be controlled manually or may be automated. In some embodiments, the containers are those used in the laboratory setting and contain various chemicals, solutions, and/or reagents. Examples of containers include carboys, 3L bottles and 6L bottles. The containers generally have a volume ranging between about 1L to about 50L. Containers suitable for use herein may be made out of any material, including but not limited to plastic (polymers, copolymers, polymer blends, copolymer blends), silicones, composites, fiberglass, metal, Pyrex®, and glass etc. The containers may comprise an opening through which a delivery conduit and nozzle may be inserted to facilitate washing of an interior space of the container (see Figure 3 herein). The containers may have any size or shape, and the container's opening may have any diameter.

Figure 1 depicts a first non-limiting embodiment of an apparatus 1 of the present disclosure comprising an array of interconnected fluid delivery members 50A. Each fluid delivery member 50A comprises a nozzle 10 and a delivery conduit 40.

In some embodiments, the delivery conduit 40 comprises at least one valve 15 for regulating fluid flow (or pressure) to the nozzle 10.

The interconnected fluid delivery members 50A together constitute manifold 80 which, together with delivery conduits 40 and nozzles 10, is in fluidic communication with two support conduits 60 and 61. The fluid delivery members

50A may be spaced at regular intervals from each other or, alternatively, each may be spaced at different intervals from each other. In some embodiments, the fluid delivery members are directly connected to each other, while in other embodiments they are connected through interconnect conduits 62. The support conduits 60 are arranged parallel to each other but perpendicular to the manifold 80. The conduits

60 and 61 are attached to the manifold with interconnect conduits 62. In some embodiments, the conduits 60 and 61 are constructed from two or more conduit segments 63, where each conduit segment is joined with an interconnect conduit 62. The skilled artisan will appreciate that any support conduit 60 or 61, conduit segment 63, or interconnect conduit 62 may comprise one or more valves (manual or electrically actuated) to regulate fluid flow through that conduit piece.

In some embodiments, conduit segment 63 further comprises an additional port, which may be used to deliver a different fluid into the apparatus than that introduced at the inlet 30. In some embodiments, the additional port allows a second fluid to mix with a primary fluid. For example, and as discussed further herein, a disinfectant or decontamination fluid may be introduced in a concentrated form and allowed to mix with the fluid introduced at inlet 30 such that a fluid mixture, having a certain concentration, may be dispersed from the nozzles. The amount of fluid entering from the port may be separately regulated so as to vary the amount of fluid that enters from that location and thus the overall concentration of the mixture introduced into the system. In some embodiments, the fluid introduced at the port is reduced over time, e.g. tapered gradually or reduced in a step-wise manner. The manifold may have any length, but generally will be sized to fit the width of a sink or other wash basin. In some embodiments, the manifold ranges from between about 16 inches (40.64 cm) to about 36 inches (91.44 cm) in length. The support conduits, like the manifold, may have any length and are generally sized to fit the depth of a sink or other wash basin. In some embodiments, the support conduits range in size from about 8 inches (20.32 cm) to about 24 inches (60.96 cm). In some embodiments, additional structure is incorporated into the apparatus such that the manifold, fluid delivery members, and containers (see Figure 3) are posited over the sink or wash basin, and structural members (which may be in fluidic communication with the apparatus) are positioned on a counter or laboratory bench top to support and/or suspend the apparatus.

A first support conduit 60 terminates at a fluid inlet 30 which is in fluidic communication with a fluid source. The fluid inlet 30 may comprise a fitting for coupling to tubing or other conduits such that the apparatus may be connected to a fluid source (or another apparatus, e.g. an upstream washing apparatus). The inlet may also comprise a valve 31 so as to regulate fluid fluid from the inlet. A second support conduit 61 terminates with an end member 35. In some embodiments, the end member 35 may be a cap that maintains fluid pressure throughout the apparatus 1. In some embodiments, the end member 35 may comprise a valve to facilitate the discharge of fluid from the apparatus or to regulate pressure or fluid flow. In other embodiments, the end member may comprise a fitting which allows it to couple to another tube or conduit so that multiple washing apparatuses 1 or 2 (or the apparatus depicted in Figure 5) may be linked together. The skilled artisan will recognize that the apparatus of the present disclosure may comprise more than one inlet (e.g. so as to provide a mixture of different fluids from different sources), and any inlet may be provided at any part of the apparatus.

In operation, a fluid enters the support conduit 60 through inlet 30. The fluid is then transferred from the support conduit 60 to the manifold 80. From the manifold 80, the fluid may enter each fluid delivery member 50A. From the fluid delivery member 5 OA, the fluid enters the delivery conduit 40 and is dispersed from nozzle 10.

While Figure 1 depicts the apparatus 1 as comprising seven fluid delivery members 50A, the apparatus 1 may have any number of fluid delivery members. In some embodiments, the number of fluid delivery members range from between 1 to 12. In other embodiments, the number of fluid delivery members ranges from between 2 to 8.

The fluid delivery members 50A of Figure 1 are fixed in position. While Figure 1 depicts that each fluid delivery member 50A is arranged at a 90 degree angle relative to the plane of manifold 80 and support conduits 60 and 61, the fluid delivery members 50A may be independently set at any angle relative to the plane (x,y), so as to accommodate containers having different shapes or having openings at different positions. For example, three of the fluid delivery members may be oriented such that they are positioned at a 90 degree angle relative to the plane of the manifold, while three other fluid delivery members may be oriented such that they are positioned at a 70 degree angle relative to the plane of the transfer conduit.

The embodiment depicted in Figure 2 is similar to that illustrated and described with regard to Figure 1. As such, any components described for the embodiment of Figure 1 may also be applied to the embodiment of Figure 2. Figure 2 depicts a second non- limiting embodiment of an apparatus 2 of the present disclosure, again comprising an array of interconnected fluid delivery members 50B. Each fluid delivery member 50B comprises a nozzle 10, a delivery conduit 40, and optionally a valve 15, including a pressure regulating valve. The interconnected fluid delivery members 50B together constitute manifold 80 which, together with delivery conduits 40 and nozzles 10, is in fluidic communication with two support conduits

60 and 61. The fluid delivery members 50B may be spaced at regular intervals from each other or, alternatively, each may be spaced at different intervals from each other. As with the embodiment depicted in Figure 1 , a first support conduit

61 terminates at a fluid inlet 30, which is in fluidic communication with a fluid source. A second support conduit 61 terminates with an end member, which may comprise a valve, a fitting, and/or a cap. In operation, an aqueous fluid enters the support conduit 60 through inlet 30. The aqueous fluid is then transferred from the support conduit 60 to the manifold 80, where it enters the delivery conduits 40 and is dispersed from nozzles 10. The fluid delivery members 50B are rotatable around the axis of the manifold.

While Figure 2 depicts that each fluid delivery member 50B is arranged at a 90 degree angle relative to the plane of the manifold 80 and support conduits 60, the fluid delivery members 50B may be independently set (and dynamically changed) at any angle relative to the plane (x,y), so as to accommodate containers having different shapes or having openings at different positions. For example, three of the fluid delivery members may be oriented such that they are positioned at a 90 degree angle relative to the plane of the manifold, while three other fluid delivery members may be oriented such that they are positioned at a 60 degree angle relative to the plane of the transfer conduit. The apparatus depicted in Figures 1 and 2 further comprises at least one cross- member 20. The cross-member 20 is believed to increase the rigidity of the apparatus such that the apparatus may support the weight of containers placed thereon or to help support the conduits. The cross-member is arranged such that it bridges support conduits 60 and 61. The cross-member 20 may be any rigid support, brace, pipe, or tube that connects the two opposing support conduits 60 and 61 of the apparatus. In some embodiments, the cross-member 20 is comprised of a plastic, metal, or composite bar that may be solid or hollow and which is connected to the conduit via a fastener or clamp (see, for example, Figure 2). In other embodiments, the cross-member 20 is itself a conduit and is in fluidic communication with support conduits 60 and 61, by way of an interconnect conduit

62, and thus facilitates the transfer of fluid through the apparatus. This type of cross-member may contain a valve to regulate fluid flow. In some embodiments, the cross-member 20 is adjustable, such that when modular fluid delivery members (see Figure 4) are assembled into a manifold, a single cross-member may be used to accommodate many different configurations. In some embodiments, the cross- member is a telescoping support or brace whose size may be adjusted dynamically. The skilled artisan will appreciate that any of the conduits or fluid delivery members, may be further reinforced with supports or braces to introduce rigidity into the apparatus and to facilitate movement of the apparatus. Figure 3 depicts a third embodiment of the present disclosure, comprising the apparatus depicted within Figure 2. Figure 3, however, illustrates the placement of differently sized containers 100 and 110 onto the apparatus. The apparatus depicted in Figure 3 may be constructed so as to accommodate any number of containers in any configuration, and to accommodate any container having any volume, shape, size, or weight. While not illustrated in Figure 3, each of the containers 100 and 110 have an opening through which the delivery conduit 40 (and nozzle 10) is inserted. In operation, the aqueous fluid is delivered from nozzles 10 to facilitate delivery of the fluid to the interior space of the containers. As the fluid is delivered into the container, it washes the interior of the container, and the aqueous fluid, along with any residues present within the container prior to washing, is allowed to drain out of the container opening. Figure 3 also depicts that the cross-member 20 may be utilized to support the various containers installed onto the apparatus.

Figure 4 illustrates a fluid delivery member 50B having a delivery conduit 40, a nozzle 10, and a valve 15. The fluid delivery member member 50B comprises a junction inlet 51 and a junction outlet 53 such that the fluid delivery member 50B may be connected to other fluid delivery members (fixed or rotatable), conduits, interconnects, "quick connects", or spacers to form a manifold comprising a series of interconnected fluid delivery members. The modular fluid delivery member 50B allows for one of skill in the art to assemble a washing apparatus having any desired number of fluid delivery members to facilitate washing of any desired number of containers and to fit any desired workspace (e.g. a sink or other laboratory basin).

Figure 5 illustrates an alternate embodiment of a washing apparatus which is configured to accommodate larger sized containers, such as those containers having a size of 20L or greater (e.g. carboys). The washing apparatus of Figure 5 comprises an inlet 30 (and an optional valve 31) which is in f uidic communication, by way of an interconnect conduit 62, with conduits 65 and 70. A delivery conduit 40, comprising a nozzle 10, is connected to conduit 70 and in fluidic communication with conduits 65 and 70 such that an aqueous fluid may be delivered through the inlet 30 and to the nozzle 10. The delivery conduit comprises an optional valve 15 to regulate fluid flow to the nozzle 10. The conduit 70 comprises two end members 35. In some embodiments, the end member 35 may be a cap that maintains fluid pressure throughout the apparatus 3. In some embodiments, the end member 35 may comprise a valve to facilitate the discharge of fluid from the apparatus. In some embodiments, the end member may comprise a fitting which allows it to couple to another tube or conduit so that multiple washing apparatuses 3 may be linked together.

The fluid delivery members, while depicted as being serially connected to one another in Figures 1, 2, and 3 may also be connected in various other ways as will be appreciated by those of ordinary skill in the art. For example, each fluid delivery member may be connected in a "parallel" arrangement as depicted in Figures 6 A and 6B.

The conduits and fluid delivery members may independently have any size and shape. For example, the delivery conduits 40 may have a size ranging from between 0.75 inches (1.905 cm) and 6.5 inches (16.51 cm) in length. By way of further example, the delivery conduits may have a diameter ranging from between 0.25 inches (0.635 cm) to about 1.5 inches (3.81 cm) and may vary depending on the size of the opening of the container being washed. In some embodiments, some delivery conduits may have a first size while other delivery conduits may have a second size (length and/or conduit diameter). Any of the conduits may have any size and one of skill in the art will select an appropriate length of conduit such that fluid delivery members are spaced at desired intervals from each other (e.g. to accommodate containers having different volumes and/or sizes). The conduits may have any interior shape or diameter to accommodate different volumes and/or flow rates of aqueous fluid. For example, a cross-section of any conduit may be circular, oval, square, etc. The skilled artisan will appreciate that given a constant flow rate at an inlet, the velocity of the aqueous fluid moving through the conduit may be altered based on the interior diameter of the conduit. In some embodiments, the conduit may have a variable interior diameter that changes as the distance from the inlet increases so as to maintain a constant flow of fluid (and/or pressure) throughout the apparatus.

The components of the apparatus of the present disclosure may be constructed of any material. In some embodiments, the components are constructed of materials that are resistant to the fluids used in operation of the apparatus. In other embodiments, the components are constructed of rust-proof materials or materials which have been treated with rust-proof or rust-resistant coatings. In yet other embodiments, the components are constructed of polymers, polymer blends, copolymers, and co-polymer blends as known to those of ordinary skill in the art. In yet further embodiments, components are constructed from synthetic rubbers, phenol formaldehyde resins, nylons, polyvinyl chloride (PVC or vinyl), polystyrene, polyethylene, polypropylene, polyacrylonitrile, polyvinyl butyral ("PVB"), silicone, polyoxymethylene ("acetal"), acrylonitrile butadiene styrene ("ABS"), and any combination thereof. The fluid delivery members 50A and 50B may contain one or more valves. For example, the fluid delivery members 50A and 50B may contain a valve which regulates fluid flow through the fluid delivery member, to the delivery conduit 40, and/or between interconnected fluid delivery members. By "regulating fluid flow" it is meant that the flow of fluid through the fluid delivery member, and hence the volume of fluid passing through the fluid delivery member, may be reduced or completely stopped. In some embodiments, a valve 15 is provided within the delivery conduit 40 to regulate fluid flow or pressure flow directly to nozzle 10. In some embodiments, the valves may serve to turn off particular nozzles in a washing apparatus or to scale back the volume of fluid being delivered from any particular nozzle (e.g. to accommodate containers having larger or smaller sizes and volumes). The valves employed may be manually operable, self-regulating, or electronically actuated.

In some embodiments, a valve operated by a timer (e.g. manual or electronic) is inserted between the inlet 30 and the fluid source so as to reduce or stop fluid flow through the apparatus after a pre-determined amount of time has passed. It is believed that incorporation of such a valve and timer means allows for the unsupervised use of the washing apparatus and/or prevents the unnecessary waste of aqueous fluid. The timer may be set such that the valve closes after a predetermined period of operation. For example, the timer may command the valve to close after fluid flows through the apparatus for a time period ranging from between about 2 minutes to about 30 minutes. In some embodiments, the time period ranges from about 5 minutes to about 20 minutes. In some embodiments, the fluid valve may comprise a built in timer.

The apparatus of the present disclosure is connected to a fluid source. The apparatus may be directly connected to a source that provides for fluid flow (e.g. a sink). Alternatively, the apparatus may be connected to a pump or other means to actively deliver fluid to the apparatus while allowing for recirculation of the fluid. Of course, the skilled artisan will recognize that any number of different fluid pumps may be utilized and regulated to provide the desired fluid flow rate and volume. The pump may comprise control logic, sensors, or meters which monitor the fluid flow rate and fluid flow volume through the system. In some embodiments, the pump may deliver a pre-determined volume of fluid through the apparatus. In some embodiments, the pre-determined volume of fluid ranges from between about 10L to about 100L. In other embodiments, the pre-determined volume ranges from between about 15L to about 50L.

In some embodiments, the fluid for washing is an aqueous fluid. In some embodiments, the fluid is distilled and/or deionized water (hereinafter "water"). In other embodiments, the fluid is a mixture of water and a surfactant. In yet other embodiments, the fluid is a mixture of water and at least one of an antibacterial agent or an antifungal agent. In other embodiments, the fluid is a mixture of water and a disinfectant, such as a quaternary ammonium disinfectant (e.g. Lysol®). The skilled artisan will also recognize that the system may be adapted for use of any fluid or solution, whether it is aqueous or non-aqueous (including acidic and basic solutions), and may be further adapted for the use of solvents or solvent systems (including volatile organic solvents) as needed. In some embodiments, multiple fluid sources are present and each are in communication (e.g. connected to) the apparatus of the present disclosure. In these embodiments, valves may control which fluids are provided to the apparatus and may also regulate the concentration of any fluid provided to the apparatus so that mixtures of fluids (having various concentrations) may be delivered to the containers.

In another embodiment, the nozzles 10 may contain a sensor whereby the nozzle only dispenses fluid if the sensor detects that a container has been placed over the nozzle 10 and/or delivery conduit 40. When the sensor determines that no container has been placed, it sends signals directly to a valve or to a computer or control module that controls the valve to close. Likewise, when the sensor determines that a container has been placed, it sends signals directly to a valve or to a computer or control module that controls the valve to open, and thereby permit fluid flow from the nozzle and into the interior space of the container. In this way, containers may be installed and removed from the apparatus while other containers are being washed, and this allows for increased runtime and efficiency. In some embodiments, rather than utilize an electronic sensor, a lever arm is used to mechanically open and close valves, where the lever arm is actuated by means of the weight of the bottle or container disposed thereon.

The nozzles 10 may be any type of spray nozzle known to those of ordinary skill in the art. In some embodiments, the nozzle is selected from the group consisting of plain-orifice nozzles, shaped-orifice nozzles, surface-impingement single-fluid nozzles, pressure-swirl single-fluid spray nozzles, solid-cone single-fluid nozzles, and compound nozzles. In some embodiments, the nozzles are rotating stream nozzles or pop-up nozzles, as known to those of ordinary skill in the art. The material of construction of the nozzle is selected based on the fluid properties of the fluid that is to be sprayed. Spray nozzles are most commonly fabricated from metals, such as brass, stainless steel, and nickel alloys, but plastics such as polytetrafluoroethylene, polyoxymethylene (acetal), ABS, PVB, and polyvinyl chloride may also used. Each fluid delivery member 50A or 50B may comprise the same or different nozzle. In some embodiments, the nozzles spray 360 degrees within the container. In other embodiments, the nozzles spray less than 360 degrees, e.g. 180 degrees, 90 degrees, etc. In other embodiments, the nozzle is selected such that it dispenses fluid with sufficient pressure and coverage such that all surfaces of the interior of a container are sufficiently wetted with fluid.

In some embodiments, the apparatus may be optionally connected to an air line, such as through a second inlet in one of the conduits, so as to allow filtered air (or an inert gas) to be blown through the apparatus to discharge any remaining water. In other embodiments, the apparatus may be configured such that after a cleaning operation is performed with an aqueous fluid, air is pumped through the apparatus, through the nozzles, and into the containers to facilitate removal of excess aqueous fluid or drying of the containers.

The apparatus may be operated manually or may be automated. For example, the apparatus may be connected to computer, programmable controller (e.g. a programmable logic controller, "PLC"), custom-build controllers, or other control modules (herein "computer") that controls a pump (and pump parameters). In addition, where the apparatus comprises one or more electronically controlled valves, the computer may be programmed to control the operation of those values, where each valve may be controlled independently. In other embodiments, a user may program the computer to provide for a certain pre-determined flow rate or quantity of water to flow through the entire apparatus or any individual fluid delivery member, delivery conduit, and/or or nozzle, such as by regulating fluid flow at the inlet, at a pump, or any of the valves. The skilled artisan will recognize that the parameters for operation may be based on the fluid being introduced into the apparatus, the size of the containers, the cleanliness of the containers, etc. In some embodiments, the system allows for the remote monitoring and/or the remote control of the apparatus and any connected components (e.g. valves, timers, etc.).

A representative system 100 for implementing the invention includes a washing apparatus 120, and computer device 130, which may be a general-purpose or special-purpose computer. For example, computer device 130 may be a personal computer, a notebook computer, a personal digital assistant ("PDA") or other hand- held device, a workstation, a minicomputer, a mainframe, a supercomputer, a multi-processor system, a network computer, a processor-based consumer electronic device, or the like.

Then, the cleaning fluid is washed from the containers by means of the apparatus (or system) and method described herein.

In some embodiments of the method, a single fluid is provided to the apparatus. In other embodiments, multiple different fluids (or the same fluid having a different concentration of one or more components) are introduced into the system, and the different fluids are introduced at different sections of the apparatus or at different times. The skilled artisan will appreciate that, as provided herein, a second concentrated fluid may be introduced at a port different than the inlet valve 30, and the concentrated fluid may be allowed to mix with a first fluid introduced at inlet 30. Of course, the concentration of the mixed fluid may be varied based on the amount of second concentrated fluid introduced or metered into the apparatus. Although the invention herein has been described with reference to particular embodiments, it is to be understood that these embodiments are merely illustrative of the principles and applications of the present invention. It is therefore understood that numerous modifications may be made to the illustrative embodiments and that other arrangements may be devised without departing from the spirit and scope of the present invention as defined by the appended claims. The foregoing written specification is considered to be sufficient to enable one skilled in the art to practice the invention.
