Definitions

  • THE PRESENT INVENTION relates to an apparatus for dispensing fluid compositions and, particularly to apparatus for dispensing, in desired proportions, two different fluid compositions which cure when mixed together and which have different degrees of compressibility.
  • the present invention is directed to such an apparatus suitable for the storage, shipping, proportioning, mixing and dispensing of at least two such different fluid compositions.
  • Known apparatus for dispensing such fluid compositions suffer from a number of disadvantages. Unlike hydraulic liquids, most single and multicomponent adhesives, sealants and mastics contain a certain amount of entrained air which becomes mixed into the composition or compositions during formation or compounding thereof. The level of such entrained air may be tolerated or controlled for technical and commercial reasons. Additionally, some forms of fillers employed in such compositions may be compressible. Examples of such compressible fillers are microglass spheres or balloons. It is known for fluid components to be loaded, for dispensing, into a suitable cartridge. However, air bubbles may be trapped within a cartridge containing the component or components during loading of the component into the cartridge, and such trapped air bubbles may be compressed and expanded during dispensing cycles. The cartridge body may expand and contract due to supported wall clearances or unsupported wall movement.
  • the more compressible, less hydraulic, composition predominates in the mixed composition, and the extent of this predomination is substantially equal to the volume of the more compressible material which should have been mixed with the less compressible material during the initial starting operation to achieve the desired predetermined proportional ratio.
  • This stopping or final run-off is off-ratio. Assuming that the unit is at rest for a period of time to allow complete decompression to take place, it is likely that the mixer will contain art incorrectly high proportion of the more compressible, less hydraulic composition. Therefore, when pressure again is applied to commence dispensing, a mixture having a high proportion of the more compressible component will initially be discharged, and this will be followed by the discharge of a mixture having a high degree of the less compressible component.
  • the invention provides apparatus for dispensing of at least two different fluid compositions, said apparatus comprising: a cartridge having therein plural separate chambers for containing separate fluid compositions to be dispensed; a neck portion provided at a discharging first end of said cartridge; plural separate passageways extending through said neck portion, each said passageway opening into a separate respective said chamber, the arrangement being such that the simultaneous application of pressure to the fluid compositions in each said separate chamber causes, in cooperation with a back pressure from the restriction of said passageways, compression of the fluid compositions, and thus causes the fluid compositions to be extruded in a predetermined ratio through the respective said passageways; and means for controlling the flow of the fluid compositions through the respective said passageways, for preventing run-on of the fluid compositions through said respective passageways due to decompression of the fluid compositions upon removal of the pressure, and thereby for preventing dispensing of the fluid compositions through said respective passageways in a ratio other than said predetermined ratio, said controlling means comprising a valve member having therethrough plural
  • This arrangement enables the prevention of run-on of any of the fluid compositions.
  • movement of the valve member to the closed position thereof closes the passageways and thereby prevents any run-on whatsoever of any of the fluid compositions.
  • Such closing of the passageways also controls the flow of the fluid compositions through the passageways, and additionally such closing of the passageways prevents uneven run-on of the plural fluid compositions, thereby preventing the occurrence of the above discussed off-ratio dispensed portions.
  • the apparatus has been found to be particularly suitable for dispensing plural fluid compositions having different degrees of compressibility in desired proportions.
  • the chambers have respective volumes selected to achieve extrusion of the respective fluid compositions at the desired predetermined ratio.
  • the neck portion preferably extends forwardly from the first end of the cartridge.
  • the apparatus may include mixing and dispensing means connected to the neck portion for receiving the plural fluid compositions extruded through the respective passageways, for mixing the plural fluid compositions to form a mixed composition, and for dispensing such mixed Composition
  • the mixing and dispensing means may comprise a nozzle structure adapted for removable connection to an outer surface of the neck portion.
  • the nozzle structure may include a nozzle member positioned at the discharge end of the neck portion and having therein a fixed mixing element capable of achieving mixing solely due to the pressure of extrusion of the fluid compositions, and a flanged coupling fitting over a portion of the nozzle member and threaded onto the outer surface of the neck portion, thereby holding the nozzle in position against the neck portion.
  • the valve member is mounted in the neck portion for rotation between said open and closed positions.
  • the neck portion includes an enlarged block portion having therethrough an opening transversely interrupting and intersecting the plural passageways and said valve member includes a stem portion rotatably fitted within such opening, said passage portions comprising parallel holes extending through the stem portion in directions transverse to the rotational axis of the stem portion.
  • the stem portion may have a cylindrical configuration.
  • the valve member may further include a head portion integral with a first end of the stem portion at a location exterior of the block portion and having an irregular configuration enabling engagement thereof by a tool for rotation of the valve member.
  • a second end of the stem portion may have therein a groove at a location exterior of the block portion, and a lock device may fit within the groove for retaining the valve member within the block portion.
  • the plural separate chambers of the cartridge include a cylindrical first chamber and an annular second chamber coaxially surrounding the first chamber.
  • the first and second chambers may respectively contain first and second fluid compositions which cure when mixed together.
  • the drawings illustrate an apparatus for proportioning, a mixing and dispensing two fluid compositions or components which cure when mixed together.
  • the two fluid compositions may be components of a known adhesive, sealant or mastic system, as well as other systems the components of which cure when mixed together, as will be apparent to those skilled in the art. It is to be understood however that the present invention is not intended to be limited to a two component system, but is employable for a system capable of proportioning, mixing and dispensing of more than two components. Furthermore, it is intended that the present invention be directed to an apparatus for proportioning and dispensing plural fluid compositions, as well as to an apparatus for proportioning, mixing and dispensing plural fluid compositions.
  • the illustrated apparatus includes a cartridge, generally indicated at 2, having therein a first, for example cylindrical, chamber 4 surrounded by a second, for example annular chamber 6.
  • the two chambers are entirely separate from each other and are adapted to contain respective fluid compositions or components which cure when mixed together and which have different degrees of compressibility.
  • the volume of each chamber may be selected to achieve extrusion of the compositions at a desired ratio.
  • a neck portion 8 extends forwardly from a disdharge end of the cartridge 2.
  • the neck portion 8 has first and second passageways 10, 12 extending therethrough each opening into a respective one of the chambers 4 and 6.
  • the ends of the chambers 4 and 6 opposite to the neck portions 8 are sealed and closed by respective closure members 14 and 16.
  • Suitable means may be provided to apply pressure to the closure members 14 and 16 whereby the compositions may be discharged from the cartridge 2.
  • the fluid compositions Upon simultaneous application of pressure to the closure members 14, 16, and thereby to the fluid compositions in chambers 4, 6 respectively, the fluid compositions are urged toward the discharge end of the cartridge. Due to a back pressure created by the restriction caused by the passageways 10, 12, as well as by a mixing device 36, to be discussed in more detail below, which may be attached to the neck portion 8, the two fluid compositions tend to be compressed. However, as the two compositions have different degrees of compressibility, the less compressible materiall will begin to discharge first through its respective passageway when the passageways 10, 12 are open.
  • Apparatus of the present invention is provided with a structure for controlling the flow of the two fluid compositions through passageways 10, 12 to prevent run-on of the two fluid compositions through the respective passageways 10, 12 due to the different decompression rates of the fluid compositions upon removal of the extrusion pressure, and thereby to prevent dispensing of the two fluid compositions through the respective passageways 10, 12 in ratios other than the desired predetermined ratio.
  • a valve member generally indicated at 18.
  • the valve member 18 includes a stem portion 20, preferably cylindrical in shape, and is rotatably mounted within the neck portion 8.
  • First and second passage portions, in the form of holes 22, 24, respectively, extend through the stem portion 20 which is sealingly rotatable within an opening 26 extending through an enlarged block portion 28 of neck portion 8.
  • the block portion 28 has an opening therethrough that transversely interrupts the passageway 10, 12 and receives the stem portion 20 of the valve member 8. More specifically, the valve member 18 is rotatable with respect to the block portion 28 between an open position, illustrated in Figures I and 3, whereat the passage portions 22, 24 are aligned with respective passageways 10, 12 thereby permitting extrusion of the fluid compositions through the passageways in the desired predetermined ratio, and a closed position, illustrated in Figure 2, whereat the passage portions 22, 24 are out of alignment with the respective passageways 10, 12 and the passageways 10, 12 are blocked by the valve member, thereby preventing any flow of the fluid compositions through the passageways.
  • the valve member has, at a first end thereof, a head portion 30 that is integral with stem portion 20, is located exterior to the block portion 28 and has an irregular configuration, such as a hexagonal configuration, enabling engagement thereof by a suitable tool for rotation of the valve member.
  • An alignment device such as a straight line indicator 32, may be provided on the head portion 30 to indicate the orientation of holes 22, 24 and thereby to provide a visual indication of the position of the valve member.
  • a second end of the stem portion 20 may have therein a groove at a location exterior of the block portion 28, to receive a suitable element, such as a lock ring 34, that may be fitted within such a groove for retaining the valve member 18 within block portion 28.
  • a mixing and dispensing structure shown generally at 36 in Figure I, may be connected to neck portion 8 for receiving the plural fluid compositions extruded through the respective passageways 10, 12 for mixing such plural fluid compositions to form a mixed composition at the desired predetermined ratio, and for dispensing such mixed composition.
  • the mixing and dispensing structure 36 includes a nozzle removably connected to the outer surface of the neck portion 8. Specifically, a nozzle member 38 is positioned at a discharge end of neck portion 8 and fixed mixing elements 40, capable of achieving mixing solely due to the pressure of extrusion of the fluid compositions, are positioned within the nozzle.
  • a flanged coupling 42 fits over a portion of nozzle member 38 and is threaded onto the outer surface of neck portion 8, to hold the nozzle member 38 in position against the neck portion.
  • the mixing and dispensing structure 36 is intended to be an in-line motionless mixing device. It will be apparent from the structure illustrated in Figure I, that the two fluid compositions do not come in contact until they are discharged into the nozzle member 38. Thus, the fluid compositions do not mix and cure in an area that could cause locking of the structure 36 onto the neck portion 8, and the structure 36 may readily be removed when desired. The two fluid compositions never mix within the internal structure of the cartridge 2, the neck portion 8 or the valve member 18.
