The present disclosure relates generally to fluid dispensing systems. More particularly, the present disclosure relates to dispensing manifolds that provide a single container having a single exit with one or more outlets from which a fluid can be controllably dispensed; a system having a force generation mechanism, a container holding a fluid or substance, and dispensing mechanisms all on one machine, i.e., a carrier; a system that may also include a pressurized air source that assists a flow of a fluid; and a system that allows for a continuous flow a substance.
Containers are used to hold liquids until it is desired to dispense such liquids. A force is applied to the outside of the container to deform the container and dispense the liquid. However, such deformation of a container to dispense a liquid is random and causes undesired consequences. For example, in a sausage caulking gun or similar operation, a seal between the dispensing components is difficult to maintain and the flexible wall of the container is able to slip between a plate and an inside wall of a vessel the container is within. This condition is often referred to as “blow by” and causes a significant portion of the liquid to be stuck within the blown by portion of the container. This significant portion of the liquid is then unable to be dispensed.
Force generation systems produce a force which acts on a container holding a substance to dispense the substance from the container. Force generation systems need to be able to stop a flow of the substance when desired. Conventional systems have containers, force generation systems, and dispensing portions that do not form integral systems and that are separate and apart from each other.
The present disclosure provides a variety of dispensing manifolds which are removable connectable to a single deformable container having a single exit portion. The dispensing manifolds of the present disclosure provide a single deformable container having a single exit with one or more outlets from which a fluid can be controllably dispensed.
The present disclosure also provides a single force generation mechanism, a deformable container holding a fluid or substance, and dispensing mechanisms all on one machine, i.e., a carrier. A carrier of the present disclosure conveniently holds the components of a fluid dispensing system of the present disclosure so that a user is able to conveniently apply multiple beads of a substance simultaneously to a substrate. The carrier of the present disclosure allows a user to be able to conveniently and easily maneuver a fluid dispensing system of the present disclosure to apply a single bead or pattern or multiple beads or patterns of a fluid or substance simultaneously to a substrate.
The present disclosure also provides a system that may also include a pressurized air source that assists a flow of a fluid. The present disclosure also provides a system that allows for a continuous flow a substance.

In one exemplary embodiment, a single force generation system 90, such as a hydraulic pump, is mounted on the carrier 17 in a convenient location to be out of the way of the functionality of the dispensing system. Referring to
The frame of the present disclosure must be sufficient in structural integrity to resist the forces necessary to dispense fluids as described herein. The outer structure of the frame must be reinforced. Conventional dispensing tools utilize a rack or frame to hold canisters. The force resistance design requirements of prior art and/or conventional frames have been minimal due to the low pressure at which a friction fit seal fails. Friction fit canisters and caulking type packaging can only withstand about 40 pounds of pressure before the seal will fail and blow-by will occur. Some very well constructed canisters may withstand up to 70 pounds of pressure before the fluid spurts out of the slidable friction seal and onto the plunger plate. For this reason, conventional dispensing technology has been limited to about 3″ inch diameter. 70 pounds of pressure in a 3″ inch diameter container requires a dispensing force of only about 500 pounds. This force can easily be constrained with a simple frame such as a thin metal caulking gun or other material holding rack. The goal of the present disclosure is to dispense fluids in multiple configurations such as hoses and manifolds that utilize a deformable container to prevent blow-by. The dispensing forces required to press out fluids necessitate a structure to withstand the advancing forces of the actuator. For example, the force required to create internal fluid pressures of 300 psi in a deformable container of about 10″ inch diameter is over 23,000 pounds. When dispensing 2 deformable containers, for applications such as epoxies, the force requirement doubles to over 46,000 pounds. A holding rack or flimsy caulking gun cannot withstand these forces. The force resistance structure 190 of the present disclosure must be designed to not only hold the container and store the fluid, but it must also have sufficient reinforcement to constrain the force. The force resistant structure must be strong enough to not yield to the pushing force of the actuator and at the same time restrain the confinement structure during dispensing. Conventional racks fail to provide the structure to accomplish this force resistance. The force generation method of the present disclosure utilizes a recirculating valve hydraulic method. The valve's pressure settings can be adjusted to allow the operator controlled dispensing options thereby increasing or decreasing the speed and volume of fluid being applied to a work area.
When the confinement structure 12 is slid over the deformable container 14 then the second end 42 of the deformable container 14 is sized and shaped to provide precise linear alignment with the confinement structure 12. The deformable container 14 does not require additional securement. The confinement structure 12, with the deformable container 14 inside, can then be slid into position on the force resistance structure 190 and is held in place by gravity. The size and shape of the force resistance structure 190 is fashioned to precisely locate the confinement structure 12 and thereby the deformable container 14 in linear alignment with the actuation member 16. As the carrier 17 is relocated to a position appropriate for dispensing, the force resistance structure 190, confinement structure 12, deformable container 14, and actuation member 16 are also moved accordingly.
If the deformable container 14 were to be placed into the force resistance structure 190 without the confinement structure 12 the deformable container 14 would neither be aligned with the actuation member 16 nor would it deform as desired. The confinement structure 12 is a necessary component of dispensing from a deformable container 14.

For example, with the dispensing manifold 19 connected to the second end 42 of the container 14, the first exit 110 of the dispensing manifold 19 is an outlet for a first bead or pattern 120 of the fluid 50 and the second exit 112 of the dispensing manifold 19 is an outlet for a second bead or pattern 122 of the fluid 50. In this manner, the first exit 110 and the second exit 112 of the dispensing manifold 19 simultaneously dispense the first bead 120 and the second bead 122 on a surface. Additionally, with the dispensing manifold 19 connected to the second end 42 of the container 14, the third exit 114 of the dispensing manifold 19 is an outlet for a third bead or pattern 124 of the fluid 50 and the fourth exit 116 of the dispensing manifold 19 is an outlet for a fourth bead or pattern 126 of the fluid 50. In this manner, the first exit 110, the second exit 112, the third exit 114, and the fourth exit 116 of the dispensing manifold 19 simultaneously dispense the first bead 120, the second bead 122, the third bead 124, and the fourth bead 126 on a surface. Advantageously, the dispensing manifold 19 of the present disclosure is designed such that the first bead 120, the second bead 122, the third bead 124, and the fourth bead 126 flow evenly to the first exit 110, the second exit 112, the third exit 114, and the fourth exit 116, respectively.
Connecting a dispensing manifold 19 to the second end 42 of the deformable container 14 provides several benefits.
Furthermore, referring to
The present disclosure provides a monolithic deformable container that contains all the fluid inside the container preventing contamination of the confinement structure 12 and the actuator 16. This complete and accurate dispensing also allows for two component fluids to be dispensed with an accurate ratio. The seal 996 of the present disclosure utilizes the wall of the deformable container to prevent leakage of the fluid. This method allows the outer diameter of the actuation member to be less than the inner diameter of the deformable container which has an outer diameter that is less than the inner diameter the confinement structure. This gap is one of the numerous advantages of the present disclosure that differentiates the present disclosure from conventional systems (
Connecting a manifold 19 directly to a deformable container 14 of the present disclosure also eliminates extra fittings. It is common for flexible packaging and even some rigid packaging to have a second part or piece of a structural member with threads to provide a connecting means to a manifold. Having a connecting means as part of a deformable container 14 has the benefit of sealing the deformable container 14 for shipment to a jobsite with a lid. Many packages have to add a secondary seal for shipment. These seals are often foil that has to be punctured prior to use, or are crimped in place seals that must be cut off. The connecting means on the deformable container can be utilized for both shipment sealing and dispensing connections.
Once the connection is made to the manifold 19 a fluid can be dispensed as desired. The proper manifold can be selected to coordinate with the requirements of fluid application specifications. A single outlet manifold can be selected for caulking concrete construction joints or single bead adhesive applications. A simple wye manifold can split the flow of the fluid for either a two bead application or two separate hoses can be attached. Four bead application is common for insulation adhesives. The spacing of the manifold apertures will necessarily determine the spacing of the beads for the application. Six (6) or twelve (12) inch spacing is common. Seven bead application is also a common configuration. The manifold can also be fitted with ball valves to selectively provide various bead applications during construction process.
Dispensing directly from a deformable container 14 to a manifold 19 has a significant advantage over dispensing out of a container and through a hose. As a fluid passes through a hose friction reduces both the pressure and the speed of flow. This is often not a problem for fluids of less than about 10,000 centipoise, but as viscosity increases flow decreases. A fluid that is 1,000,000 centipoise and is pressurized to about 200 psi may only travel about 15 feet through a 1″ hose. A fluid that is about 500,000 centipoise at the same 200 psi may travel 30′ through a 1″ hose. The fluid flow comes to a complete stop. When using a manifold 19 directly connected to a deformable container 14 the distance of travel is only about 12″ to 18″. At this shorter distance, the same 500,000 centipoise fluid will dispense out of a multiple port manifold at about ½ gallon per minute operating under the same 200 psi.
Attaching a manifold 19 directly to a deformable container 14 that is in a confinement structure 12 and is being deformed by an actuation member 16 which is moved by a single force generation system and supported by a force resistance structure 190 all moving over a substrate on a carrier 17 allows the carrier 17 to be situated directly at the location of the desired fluid application. Additionally, an operator of the carrier 17 can also simultaneously be dispensing the fluid. When operating a hose the carrier 17 must be moved by one operator and the hose by a second person. Pulling the entire dispensing system and manifold on a carrier 17 allows the operator to apply parallel lines of fluid to a substrate as the carrier is being pulled along.

In an exemplary embodiment of the present disclosure, the second end 42 of the container 14 is rigid. Advantageously, a container 14 of the present disclosure having a rigid second end 42 allows for the above described quick connection mechanisms to allow for easy, quick and secure connections between a connection portion 102 of a dispensing manifold 19 of the present disclosure with a rigid second end 42 of the container 14 of the present disclosure.

Examples of single bead applications include caulking concrete joints, serpentine patterns for adhesives, and applying a flood coat on a substrate such as a concrete floor coating. On the exterior of buildings single beads work well around window, metal seams, and screw heads. Single bead applications are also used to apply adhesives in manufacturing processes. It is desirable to apply multiple beads for applications that either require a flood coat of material or when 3′ to 4′ wide rolls, sheet goods, or boards are to be adhered by applying spaced out beads. The distance between the outlets determines the distance of the beads.
As discussed above, in other exemplary embodiments, it is contemplated that a dispensing manifold 19 of the present disclosure may include any number of configurations and any number of outlets for a particular application. For example,

Advantages of using a hose 170 with a system of the present disclosure includes not just the advantages associated with the hose 170 itself, but also with the advantages associated with the entire system of the present disclosure allowing a hose 170 to be used in new ways. Conventional dispensing through a hose has been accomplished by creating a force of either air pressure that is generally less than 150 psi or by utilizing a fluid pump to generate fluid pressures of 3,000 to 7,000 psi material pressure. Thin fluids such as primers, and some paints can be moved by pressurizing a container that holds a liquid. Thicker viscosity materials such as high solid sealants, coatings, and caulks do not move through a hose at these lower pressures. Additionally, air pressure can compress, thereby making flow control difficult. When utilizing a fluid pump some materials flow well, but the pump is touching the fluid being dispensed. This contamination of the parts of a pump requires specialized training and a keen awareness to prevent materials from curing inside the system. Additionally, pumps tend to aerate fluids into particles that become airborne and land in undesirable locations. Switching between materials is not quick nor easy as it requires a full flush of the pump, fittings and other components. The systems of the present disclosure can extrude heavier viscosity adhesives, sealants and coatings of about 150,000 centipoise through hoses of 20′ to 200′. This hose length is very workable in most applications of these products. The hose itself is less expensive than the hoses that are several thousand psi ratings. This lower cost allows switching out of hoses to a new container with a different adhesive, sealant, or coating without a high financial barrier. Many applications such as flooring, siding, and roofing require a sealant be applied prior to a coating application and several different types, colors and viscosities of materials may need to be applied. The hose application with a pump or air pressure system is just not practical to accomplish all these different functions. The systems of the present disclosure provide a simple and cost effective solution for this array of application requirements. Once the fluid reaches the outlet of the hose a variety of application tools can be utilized. In exemplary embodiments, referring to

The deformable container 14 of the present disclosure combined with the collection of the exit nozzle, the fitting, the confinement structure 12, the uniquely shaped actuation member 16, and the actuator system positioned inside the force resistant structure, and all mounted on a carrier 17 with a single force generation member 90, provide a unique method of dispensing a fluid heretofore unanticipated. The embodiment shown in
Conventional canister dispensing utilizes plungers traveling into the inside of the canister. As the plunger enters into the inside of the canister the interior walls of the canister are exposed and can be observed. In an attempt to minimize the contact of the plunger with the fluid being held inside the canister, a cup is used as a separating member. The exterior of this cup is designed to provide some degree of a seal between the cup and the inside wall of the canister. This friction fit seal frequently fails, especially when the fluid provides resistance from the cold viscous material or from a clog in the exit path of the fluid that is intended to be dispensed out the other end. The leakage of the fluid is not only messy but produces a mismatch in the third fluid. Differing amounts of part A and part B are mixed to become a third fluid that does not meet the manufacturer's specifications.
The deformable containers 14 and the systems of the present disclosure prevent leakage of one component thereby ensuring accuracy of fluid mixtures. The embodiment of the present disclosure shown in
Referring to
A variety of different containers 14 containing various fluids or substances are compatible with the fluid or substance dispensing system 10 of the present disclosure. Actuation member 16 and confinement structure 12 provide a system 10 that allows for controllable deformation of a variety of different containers all on one machine, i.e., a carrier. With a particular container 14 containing a desired fluid or substance 50 to be expelled selected, the container 14 may be positioned within the interior 26 of confinement structure 12, as shown in
In some embodiments, it may be desirable for the substance 50 to exit container 14 adjacent or approximately adjacent exit aperture 32 of confinement structure 12. For example, it may be desirable for the substance 50 within container 14 to be expelled from container 14 not more than approximately three (3) inches from second end 42 of container 14. When a substance 50 such as an adhesive is to be placed on small easily movable parts that are to be assembled, the parts can be moved in close proximity to the exit aperture 32. As the adhesive is expelled, it is applied to the parts being assembled and held together by the adhesive. In some embodiments, this immediate dispensing on to a part that is easily moved to the exit aperture requires no other fitment.
In one embodiment, referring to
In some embodiments, it may be desirable for the substance 50 to exit container 14 and travel through a channel or flexible tubing, such as hose 170, for a distance before being dispensed as shown in

Advantageously, a system of the present disclosure is compatible with additional containers holding additional fluids and additional fluid receiving portions. For example, referring to
Attempting to dispense fluids which exit one container and then travel through a splitting manifold to multiple outlets provides opportunity for unbalanced dispensing. Fluid always take the path of least resistance therefore a small difference in the flow paths of a fluid will result in more fluid flowing out one aperture than another. This is often not a problem with single component fluids, but when dispensing multiple component materials such as epoxies, two part adhesives, or two part coatings, the off ratio mixture is a significant problem. In floor coating for instance, if one container dispensing a first resin component to four separate mixing manifolds this first component liquid resin will flow to the path of least resistance. One gallon of fluid resin may flow out as 1 pint to the first mixing manifold 1½ pints to the second mixing manifold, 2½ pints to the third mixing manifold, and 3 pints to the fourth mixing manifold. As the second container dispenses one gallon of fluid hardener to cure this floor coating the fluid will also flow to the path of least resistance in which case the first mixing manifold may receive 4 pints, the second mixing manifold receiving 1½ pints, the third manifold receives 2 pints, and the fourth mixing manifold receives ½ pint. While both the fluid containers dispensed 1 gallon of material the ratios of fluid resin to fluid hardener would 4:1, 1:1, 1.25:1, and 6:1 respectively. This would make the floor coating very hard very quickly in some areas and possibly never cure in other areas because of the off-ratio mixture. By maintaining a ratio of one deformable container to one mixing manifold and by keeping the containers, plungers, and speed of displacement the same for all containers, the result is four mixed fluid streams that are at a 1:1 ratio. Certainly, one skilled in this art will recognize that specific off ratio applications can be achieved by utilizing containers that are matched with the desired ratio, but the mix will be dispensed as specified not by chance. The advantage of this multiple mixed fluid streams is speed of application over those systems utilizing a single stream of mixed fluid.

In such embodiments of the present disclosure, a first deformable container is connected to a first hose and a second deformable container is connected to a second hose whereby both the first deformable container and the second deformable container are in selective fluid communication with a third hose. The first hose has an inline first check valve 422 and the second hose has an inline second check valve 424. The first check valve 422 allows flow of a fluid from the first deformable container and prevents the flow of a fluid from the second or third hoses into the first hose and therefore the first container. The second check valve 424 allows flow of a fluid from the second deformable container and the second hose while preventing flow of a fluid from the first or third hoses into the second hose and therefore the second container. As the first hydraulic cylinder exerts force on the first deformable container the increase of fluid pressure extends from the first hose to the second and third hoses. The increase in pressure on the second hose causes the second check valve 424 to close thereby preventing flow of the fluid to the second container. This blockage of flow into the second hose and the second deformable container allows the second deformable container to be disconnected from the second hose. The empty second deformable container can then be replaced and connected with a full third deformable container. When the first deformable container is fully dispensed of fluid then the second hydraulic cylinder can be actuated to begin dispensing fluid from the second deformable container through the second hose. As the fluid flow moves down the second hose it reaches the second check valve 424 and causes it to open. As fluid pressure extends from the second hose to the first and third hoses the increase in pressure in the first hose causes the first check valve 422 to close thereby preventing flow of the fluid to the first container. This blockage of flow into the first deformable container allows the first deformable container to be disconnected from the first hose. An empty first deformable container can then be replaced and connected with a full forth deformable container. This arrangement eliminates the down time associated with the removal and replacement time of a single deformable container embodiment. Construction sites require much set up time each day to get to the point where actual dispensing of a fluid can occur. The reduction of this dispensing time is extremely valuable. When caulking and sealing side walls and windows for instance, a caulking mechanic is often up in a lift. While it takes time to prepare the operator for safely getting into position, it is also imperative that the operator not be in this precarious position any longer than is necessary. The operator in the lift has the third hose for dispensing the caulking into cracks in a wall and around windows. A second operator stands ready to exchange the empty deformed containers with filled deformable containers. By setting up the deformable containers in this arrangement the time spent on the lift can be reduced and safety increased. Those skilled in the art of such an arrangement will appreciate that the operation of these two separate machines can be automated rather than manual operation by the second operator. This automation would further reduce the downtime associated with the exchange of empty deformed containers for full deformable containers.

In an exemplary embodiment of the present disclosure, the air is added to the stream just prior to exiting an opening. The fluid flow without air may be ¼″ round stream flowing at ½ gallon per minute. Introducing air pressure of about 30 psi will cause the fluid flow to spread out as it exits the aperture. The volume of material would remain at ½ gallon per minute but the pattern of the fluid flow will become random spreading out in droplets about ¼″ to ½″ in diameter over and area of about 8″ in diameter. By increasing the pressure to about 90 psi the fluid flow will remain at ½ gallon per minute and the stream will become smaller droplets of about ⅛″ diameter and create pattern of about 14″ in diameter. This technique is particularly valuable with adhesives where the droplets do not need to be as fine as a high-pressure paint spray, but rather the goal is to generally cover a surface with enough adhesive for mating a second sheet or board to the substrate. This is the case with flooring, roofing, and wall panel applications.
In an exemplary embodiment, a deformable container 14 provides a good flow, 20 to 300 psi, of a fluid or substance 50 which can then be sprayed with the assistance of pressurized air 400. Gravity, low pressure pumps, and pressure pots are used to create substance flow, but these have the disadvantage of limited substance viscosity. Many products require heating the substance to lower its' viscosity for air assisted spray applications. Some two component substances, such as waterproofing materials can be sprayed with air assist but the material quantity is limited because it must be dispensed in a dual cartridge gun. These are generally limited to about 1500 ml. To utilize a larger volume of the substance the material has to be moved from a bulk container through a hose to an air assisted spray gun. A deformable container that can withstand pressures of up to 300 psi has the advantage of moving the substance and eliminating the need for either heating or pumping.
