Definitions

  • the present invention relates generally to an apparatus for containing and dispensing a fluid under pressure and, more particularly, to such an apparatus which utilizes an expandable container member to provide a compression force on the fluid and which does not employ aerosol propellants.
  • the present invention comprises an improved apparatus for containing and dispensing a fluid under pressure which is as effective as the devices disclosed in the aforementioned patents, yet it is simpler and more economical to produce, thereby making it economically feasible for use in dispensing a wider range of fluids.
  • the present invention comprises an improved apparatus for containing and dispensing a fluid under pressure, comprising a generally rigid body member having an open top end and a bottom end with a central axis extending generally between the top and bottom ends.
  • a generally rigid elongated mandrel member extends generally along the central axis through the open top end of the body, member opening and into at least a portion of the body member.
  • An elastomeric, expandable, substantially inert fluid container member is disposed around the mandrel member.
  • the container member is generally cylindrical when unexpanded, with open top and bottom ends.
  • the container member is sealingly secured to the mandrel member proximate the top and bottom ends so that the container member is adapted to expand upon being filled with the fluid under pressure.
  • Valve means are connected to the top end of the mandrel member.
  • the valve means include a valve control passageway adapted for inserting fluid under pressure into the container member and for the selective flow of fluid from the interior of the container member to the outside of the apparatus upon actuation of the valve.
  • the improvement comprises fastener means comprised of a polymeric material for sealingly securing the container member to the mandrel member.
  • the fastener means is comprised of elongated strips of polypropylene material which are tightly wound around the outside of the container member and sonically welded. In another embodiment, the fastener means is comprised of strands of polyester yarn material which are tightly wound around the outside of the container member and t ack welded.
  • the apparatus l0 for containing and dispensing a fluid under pressure.
  • the apparatus l0 includes an outer, generally rigid body member l2, preferably formed of a molded plastic or similar material.
  • the body member l2 is generally cylindrical in shape and has a generally open top end l4 and a bottom end l6 which may be open or closed as shown but which is preferably closed.
  • a central axis (not shown) extends generally along the axial center of the body member l2 between the top and bottom ends l4 and l6.
  • the top end l4 of the body member l2 includes an annular rib or shoulder l8 having a relatively sharp edge which is adapted to receive and support the lower portion of a generally cylindrical valve means or valve assembly 20.
  • a cover member 22 of the type which is generally well known in the art and having an interior fluid passageway 24 is movably secured around the valve assembly 20.
  • the cover member 22 is rotatable with respect to the valve assembly 20 into a locked position and an open position. In the locked position, the cover member 22 is prevented from being depressed, thereby blocking actuation of the valve (not shown) within the valve assembly 20.
  • depression of the cover member 22 toward the body member l2 actuates the valve for the dispensing of fluid through the fluid passageway 24 in a manner which is well known in the art. It will be appreciated by those skilled in the art that while a particular type of cover member 22 and valve assembly 20 is presently preferred, any other suitable type of valve assembly, with or without a cover member may alternatively be employed in connection with the apparatus l0.
  • a generally rigid elongated mandrel member 26 is secured to the valve assembly 20 and extends generally downwardly from the valve assembly 20.
  • the mandrel member 26 extends generally through the open top end l4 of the body member l2 and into at least a portion of the body member l2, generally along the central axis (not shown).
  • the mandrel member 26 is formed of a molded plastic or similar material and is generally cylindrical in cross section.
  • the mandrel member 26 includes a plurality of ribs and elongated openings symmetrically arranged to form at least one flow path (not shown) therebetween to allow for the flow of fluid material therethrough.
  • a m ore detailed explanation of the structure and operation of the mandrel member 26 may be obtained from U. S. patent No. 3,876,ll5, the disclosure of which is hereby incorporated herein by reference.
  • An elastomeric, expandable membrane or fluid container member 28 is disposed around the mandrel member 26.
  • the container member 28 is formed of a substantially inert material to provide for the containment and storage of different types of fluids for an acceptable shelf-life period, without permitting the migration or permeation of the contained fluid through the container member 28.
  • Complete details regarding specific types of material which can be employed in producing the container member may be obtained from U. S. patent No. 3,876,ll5.
  • the container member 28 is generally cylindrical when unexpanded in its unfilled state, with generally open top and bottom ends, which permits the container member 28 to be conveniently installed around the mandrel member 26.
  • the inner diameter of the contained member 28 is preferably about the same as or slightly less than the outer diameter of the mandrel member 26 so the container member 28 fits snugly around the mandrel member 26.
  • the container member 28 is also sealingly secured to the mandrel member 26 proximate the top and bottom ends of the container member 28 in a manner which will hereinafter be described.
  • the container member 28 is adapted to expand, as shown in Fig. l, when filled with a fluid under pressure.
  • a fluid may be inserted under pressure into the container member 28 through the fluid passageway 24 and the mandrel member 26.
  • the pressure applied in inserting the fluid causes the container member 28 to expand as the fluid is received, as shown in Fig. l.
  • the valve When the valve is actuated by depressing the cover member 22 in the open position, fluid from the interior of the container member 28 flows through the mandrel member 26, through the valve and through the fluid passageway 24 and is expelled to the outside of the apparatus l0.
  • the elastomeric nature of the container member 28 provides the compression force required to propel the fluid out of the apparatus l0.
  • the apparatus l0 also includes means for restricting the outward expansion of the container member 28 to be primarily transversely to the central axis.
  • the means for restricting the expansion of the container member 28 comprises a stabilizer sleeve 30 disposed around the container member 28.
  • the stabilizer sleeve 30 is comprised of a plurality of generally parallel elastic strands extending generally circumferentially with respect to the central axis and a plurality of non-elastic strands extending generally parallel to the central axis. The elastic and non-elastic strands are interengaged to form a net-like or mesh-like structure.
  • the elastic strands permit the stabilizer sleeve 30 and the container member 28 to stretch, generally transversely to the central axis, while the non-elastic strands prevent the stabilizer sleeve 30 and the container member 28 from stretching in a direction generally parallel to the central axis.
  • the stabilizer sleeve 30 is generally cylindrical, with open top and bottom ends to facilitate installation of the stabilizer sleeve 30 around the container member 28.
  • the inner diameter of the stabilizer sleeve 30 when unstretched is about the same as or slightly, less than the outer diameter of the container member 28 so the stabilizer sleeve 30 fits snugly around the container member 28.
  • the stabilizer sleeve 30 is secured to the container member 28 proximate the top and bottom ends of the container member 28 in a manner described below.
  • both the stabilizer sleeve 30 and the container member 28 are secured to the mandrel member 26 by the same fastener means.
  • the fastener means comprises elongated fastener strips 32 and 34, one of the strips 32 positioned proximate the top end of the container member 28, and the other strip 34 positioned proximate the bottom end of the container member 28.
  • the strips 32 and 34 are formed of a high-strength polymeric material, preferably polypropylene.
  • Each of the strips 32 and 34 is tightly wound around the outside of the stabilizer sleeve 30 and is pulled tightly to force the container member 28 into firm engagement with the mandrel member 26 providing a tightly sealed connection between the container member 28 and the mandrel member 26 proximate the top and bottom ends of the container member 28.
  • the action of the strips forces the interior of the container member 28 into sealing engagement with a plurality of threads or ridges 27 on the mandrel member 26. Portions of the container member 28 conform to the mandrel ridges 27 to form a fluid tight seal.
  • Each tightly wound strip 32 and 34 is secured to itself, utilizing a suitable securing method.
  • each of the polypropylene strips 32 and 34 is secured to itself by sonic welding. In this manner, when fluid under pressure is inserted into the container member 28 in the manner described above, the portion of the container member between the two fastener strips 32 and 34 expands outwardly, as shown in Fig. l, while the portions of the container member beneath the fastener strips 32 and 34 form tight seals to prevent leakage of the fluid out of the ends of the container member 28.
  • the apparatus l0 further includes an elastomeric energy member 36 disposed around the stabilizer sleeve 30.
  • the energy member 36 is adapted to expand with the container member 28 and the stabilizer member 30 when the container member 28 is filled with a fluid under pressure. Further, the energy member 36 is adapted to provide an inward compression force on the stabilizer sleeve 30 and the container member 28 to assist in expelling fluid from the container member 28 upon actuation of the valve.
  • the energy member 36 is generally cylindrical when unexpanded with open top and bottom ends to facilitate installation of the energy member 36 around the stabilizer sleeve 30.
  • the, inner diameter of the energy member when unexpanded is about the same as, or slightly less than, the outer diameter of the stabilizer sleeve 30 so that the energy member 36 fits snugly around the stabilizer sleeve 30.
  • the energy member is formed of a natural rubber material or some other material having elastomeric properties similar to that of natural rubber.
  • FIG. 3 there is shown an alternate embodiment of the invention.
  • the embodiment shown in Fig. 3 is the same as that of the embodiment shown in Figs. l and 5, except that the embodiment shown in Fig. 3 does not include an energy member 36.
  • the apparatus relies upon the elastomeric nature of the container member 28 and the stabilizer member 30 to provide the compression force necessary to expel the fluid from the apparatus l0.
  • the container member 28 In fabricating an apparatus l0 of the type shown in Fig. 3, it may be desirable to make the container member 28 greater in thickness than that required in connection with the embodiment of Figs. l and 5. In this manner, the container member 28 will provide additional compressive force.
  • the container member 28 may be of a different material than may be employed with the embodiment of Figs. l and 5.
  • Fig. 2 shows a second alternate embodiment of the present inv ention, also shown generally as l0.
  • the embodiment of Fig. 2 is substantially the same as that of Fig. l, except that the embodiment of Fig. 2 does not include a stabilizer member 30.
  • the embodiment of Fig. 2 includes a container member 28 substantially the same as that employed in the embodiment of Figs. l and 5 and an energy member 36 which is also substantially the same as that of the embodiment shown in Figs. l and 5.
  • the embodiment of Fig. 2 further includes different fastener means for securing the container member 28 to the mandrel member 26.
  • the fastener means comprises strands of a polymeric yarn material 32' and 34' preferably of polyester, one of the strands 32' positioned proximate the top end of the container member 28 and the other strand 34' positioned proximate the bottom end of the container member 28.
  • the polyester strands 32' and 34' are formed of a high strength polyester material of a type well known in the art.
  • Each of the two strands 32' and 34' is tightly wound around the outside of the container member 28 and is pulled tightly to force the container member 28 into sealing engagement with the mandrel member 26 to provide a tightly sealed connection at each end of the container member 28.
  • Each tightly wound strand is secured to itself, utilizing a suitable securing method.
  • the polyester strands 32' and 34' are secured by tack welding, which also prevents the strands 32' and 34' from unraveling.
  • Fig. 4 shows yet another embodiment of the present invention.
  • the embodiment shown in Fig. 4 is substantially the same as that of Fig. 2, except that there is no energy member 36.
  • the container member 28 is employed not only to contain the fluid but also to provide the entire compression force for dispelling the fluid from the apparatus l0.
  • the container member 28 is secured to the mandrel member 26 by fastener means comprised of strands of polyester yarn material 34' (only one shown in Fig. 4).
  • Fig. 6 shows yet another embodiment of the present invention.
  • the embodiment shown in Fig. 6 is substantially the same as the embodiment shown in Figs. l and 5, and includes a container member 28 surrounded by a stabilizer sleeve 30 and an energy member 36.
  • the stabilizer sleeve 30 and container member 28 are sealingly secured to the mandrel member l6 utilizing strands of polyester yarn material 34' (only one shown in Fig. 6).
