Definitions

  • a portable dispenser which comprises a container holding a gaseous or gasifiable liquid propellant, in the open top of which is mounted a head structure having a valve which normally prevents outflow of the pressurized propellant but, on being opened, permits flow of propellant in gaseous (vapor) form to an ejector near the discharge port.
  • a separate product flow line is provided which communicates with the exterior of the container, and extends through the container and head structure to the ejector.
  • the ejector (sometimes called a venturi)to which separate flow lines from the product container and the propellant container are respectively connected, the outflow of the propellant when the valve is opened, reduces the pressure in the product flow line and a simultaneous outflow of the product is brought about.
  • atomization of the product commonly is effected and a spray discharge is produced.
  • the subject invention comprises a dispenser of the type described above having a product flow line member, usually extending from the bottom of the dispenser, which product flow line member is capable of piercing a hermetically sealed product container.
  • the dispenser has means for venting the product container to the atmosphere.
  • FIG. 1 is a vertical section of the dispenser and associated product flow line member.
  • FIG. 2 is an enlarged plan view along the line AA of FIG. 1.
  • the dispenser 10 holds under pressure a propellant that is either a gas or, preferably (as shown), a vaporizable liquid 11 of high volatility such as is commonly used in aerosol dispensers, e.g., a fluorinatedchlorinated hydrocarbon such as those sold under the names Freon and Genetron.
  • a propellant container is of metal.
  • a mounting cup 14 of conventional configuration is seamed at its upturned rim 15 to the bead 13 by rolling the rim 15 over the bead 13.
  • the head structure 12 includes the mounting cup 14, a valve means for control of propellant discharge, a valve actuator, an ejector-atomizer, and a dip tube 16, all of which are described below.
  • the head structure 12 as here illustrated is basically of the type described in Abplanal United States Patent No. 2,631,814 insofar as concerns the valve unit proper, its
  • the mounting cup 14, seamed to the bead 13 of the propellant container 10, has a conventional central upstanding collar 17 that in a known way mounts a valve unit.
  • the collar 17 surrounds the cylindrical plastic housing 18 of the valve unit and also, by its inturned upper flange 19, holds the outer part of the annular valve gasket 20 in place against the upper rim of the valve housing 18.
  • the valve housing 18 has a central opening 21 in its bottom wall to provide open communication with the propellant container 10 beneath; and this bottom wall serves also in a known way as the fixed abutment for a biasing spring 22 that holds the vertically movable valve body 23, at its upper shoulder, against the underside of the inboard part of the valve gasket 20,
  • the hollow valve stem 24 is of smaller external diameter than the valve body 23, and has a neck portion, of still smaller diameter, just above the top shoulder of the valve body 23, this reduced-diameter neck portion being of greater height (at the circle defined by the diameter of the valve stem) than the initial thickness of the valve gasket 20.
  • the upper part of this neck is tapered in known fashion.
  • the hollow valve stem 24 has a side port 26, extending through its Wall. That port 26 normally is closed by the inner face of a central opening in the gasket, that opening being of smaller diameter than the neck of the valve stem in order to efifect a tight closure for the side port. There is also a seal where the upper shoulder of the valve body 23 is pressed against the underside of the gasket.
  • valve gasket 20 prevents flow of the propellant into the interior of the hollow valve stem, and also prevents escape of propellant to the atmosphere past the gasket 20.
  • the valve stem is depressed, the inner part of the annular gasket 20 is bent or warped downwardly until the side port 26 in the valve stem 24 is uncovered I and a flow passage is opened between the gasket 20 and the upper shoulder of the valve body 23. Propellant then flows through the side port 26 into the interior of the hollow valve stem 24, and flows upwardly in the annular space 27 surrounding the specially provided inner tube 25, the role of which is now described.
  • This tube 25 extending through the valve stem and valve body and movable therewith, forms a part of the flow line for discharge of the product to be dispensed.
  • An extension 16 of the tube 25 passes through the central opening 21 in the bottom wall of the valve housing 18, and passes through the propellant container 10 to exit at the lower part of the propellant container 10.
  • the product flow fitment generally designated as 30, has a socket portion 31 for snugly receiving a centrally disposed tubular extension 29 of the bottom wall of the propellant container 10.
  • the base of the socket 31 has an annular shoulder 32 having a central perforation 33,
  • said shoulder 32 acting as a stop for the edge of the tubular extension 29 and the tube 16.
  • Extending from the socket 31 and shoulder 32 is a hollow member 34 which tapers to a diameter suitable for puncturing a hermetically sealed product container (not shown).
  • the outer wall of the hollow member 34 may be longitudinal splines 35 to provide a means for venting the product container during actuation of the dispenser and consequently maintain the pressure within the product container at atmospheric pressure. Without such a vent, and absent a pressure-generating product, dispensing of product will produce a decrease in pressure within the product container.
  • the actuator 40 has the overall configuration and size of a conventional aerosol button used with known dispensers in which the product and the propellant are held in a single container and are discharged together through the hollow valve stem when the valve stem is depressed by manual pressure on the button.
  • the detailed construction of the actuator is described in US. application Ser. No. 524,527 filed Feb. 2, 1966, in the name of Robert Henry Abplanalp, which application is made a part of the disclosure herein.
  • Two separated flow lines, for propellant and product respectively, are established by passages through the molded part of the head structure 12 extending from its lower end (the end that closes the open end of the propellant container up to the discharge ejector in the actuator 40 where the two streams first come together.
  • the lower end of each of the two product lines lies within the area of the top opening of the propellant container.
  • the propellant flow line to the ejector is established through the opening 21 and passage, the port 26, the annular space 27, the passages 41 and 42 to the annular nozzle passage 43'.
  • the product flow line to the ejector includes the hollow member 34, the tube 16 and the passage 25 which communicates at its upper end with the discharge nozzle 43.
  • the dispenser and fitment is inserted diaphragm with a self-closing slit, or may be a container with a resilient flap valve which is a flattened tube depending into the container such that upon removal of the needle, the tube will reclose.
  • the product flow line member may be attached to the propellant container by means other than the friction fit shown in the drawing.
  • the inside wall of the socket could be threaded to screw onto a suitably threaded nipple on the bottom wall of the propellant container.
  • the critical construction is that a relatively air-tight seal be made between the dip tube within the propellant container and the wall defining the opening in the tapered tube so that a partial vacuum. is formed in the product passage of the tapered tube.
  • a dispenser for use in discharging contents of a hermetically sealed product container, comprising a propellant container having an open top, a head structure joined to said propellant container to close its open top, said head structure comprising (a) a discharge ejector, (b) separate passages establishing flow lines to the discharge ejector from the lower end of said head structure within the area of the open top of said propellant container, one of said lines being in open communication at its lower end with said propellant container to permit propellant fiow therethrough, and (c) manually operable valve means for said propellant flow line, a product fiow line within the propellant container being in open communication at its upper end with the other flow line in the head structure and at its lower end extending through the wall of the propellant container and a hollow needle-like member suitable for piercing a hermetically sealed product container attached to the propellant container in a manner such that one end of the hollow needle-like member is in open communication with the product flow line at the place where it emerges from the propellant container.
