Definitions

  • ABSTRACT A single dose dispensing device for aspirating a product located in a replaceable container by means of compressed air is disclosed.
  • the device includes a piston-cylinder assemblyhaving a movable member and a fixed member and has a compressed air flow path therethrough with an aperture at the free end of the fixed member.
  • a product dispensing member also having a compressed air flow path therethrough is connected to the piston-cylinder assembly, the respective compressed airflow paths being in communication with one another.
  • the dispensing member further includes a product storing chamber and anaspirating means in communication with both the product storing chamber and the compressed air flow path.
  • a diaphragm member normally blocks the compressed air flow path and is adapted to open when the movable member substantially completes a compression stroke,
  • the invention relates to a dispenser and particularly to a device for dispensing a single dose of material preferably powder, by means of aspiration using compressed air, and in which the supply of dispensed material is readily replaceable.
  • fluorocarbon propellants e.g. Freon which is a commonly used propellant
  • Freon which is a commonly used propellant
  • Pharmaceutical marketers would thus prefer to have the product dispensed by air instead of the chemical vapor conventionally used as a propellant.
  • a further disadvantage of the prior art dispensing devices is leakage of propellant from the propellant car tridge during storage, which reduces the shelf life of the dispenser. Additionally, the problem of exactly matching the amount of propellant with the amount of material to be dispensed is often difficult because of leakage problem. Also because of differences between the various materials being dispensed a proper amount of propellant for the material will not suffice or will be in excess of that necessary for dispensing all of another material. In the first instance, part of the product is wasted and in the second instance part of the propellant is wasted.
  • a further disadvantage is that, with compressed gas type propellants when the propellant is running low, the dispensing of the last of the material to be dispensed can be carried out only at a very slow rate, as compared to when the dispenser is initially filled with propellant, when dispensing takes place rapidly.
  • the diaphragm member seals the compressed air flow path when product is not being dispensed.
  • a dispensing device having a piston-cylinder assembly defining a compressed air flow path therethrough and having a piston slidable therein.
  • a single dose, replaceable product dispensing member having aspirating means is removably connected to the piston-cylinder assmbly such that the aspirating means communicates with the compressed air flow path therein.
  • the product dispensing member has adiaphragm member operatively positioned across the compressed air flow path.
  • the pistoncylinder assembly preferably has a cylinder around the compressed air flow path and has a piston slidable therein.
  • a piston rod is connected to the piston for moving the piston into the cylinder.
  • FIG. 1 is a side view of the device constructed in accordance with a subject disclosure
  • FIG. 2 is a sectional elevation view of the device of 5 FIG. 1 with the parts in the rest or non-dispensing position.
  • FIG. 1 a side view of a configuration of the subject invention is disclosed.
  • a single dose, replaceable product dispensing member is inserted within and retained by a dispenser l2 and operatively communicates therewith.
  • the dispenser 12 has a piston which is operated by means of piston rod 18 to produce a compressed air supply which is fed to the product dispensing member 10 for aspiration ofthe material, preferably powder, contained in the member.
  • FIG. 2 discloses a cross sectional elevation view of the device of FIG. 1, the compressed air is generated by an air compressing pistoncylinder means which may be a hollow cylinder 14 having an aperture at one end and an aperture in the lateral surface of the cylinder at the opposite end thereof.
  • a piston member 16 is slidably positioned within the cylinder l4 and the piston rod 18 is an extension thereof which extends through the end aperture of the cylinder 14.
  • the piston member 16 has a piston face 20, the piston being slidably retained within the cylinder by means of retaining cap 22.
  • the cylinder further includes a partition member 24 having an aperture 26 therein.
  • a probe member 28 protrudes from the face of the piston in alignment with the aperture 26.
  • Compression ring 30 seals the piston head in its movement within the cylinder 14 and a return spring 32 within the cylinder normally urges the piston away from the partition member 24.
  • the piston, the partition and the cylinder define a chamber 34 for compressing air.
  • Product dispensing member 10 is a sepa'rate replaceable body which is insertable through the first lateral aperture in the cylinder as shown.
  • the dispensing end of the member 10 has an outer annular channel 36 and an inner recessed region 38 having a central passageway 39 extending from the recessed region 38 and intersecting a lateral opening 40 of a larger diameter which opens laterally out of the member 10.
  • a Venturi nozzle insert 42 is seated in the inner recessed region 38 and an aperture cover 44 sits within the annular channel 36 and fits over the Venturi nozzle insert 42; an elongated extension 46 fitting tightly against the peripheral wall 48 of the dispensing member 10.
  • a tab seal 50 is provided over an aperture in the cover and the Venturi nozzle and is removed prior to operation of the device.'This tab seal insures that the product will not become contaminated and also prevents the unintentional egress of product from the device.
  • the Venturi nozzle 42, cover 44 and member 10 define a supply chamber 45 from which passages 47 open into the central passage of nozzle 42.
  • Supply chamber 45 can be filled by loading a preferably powdered product through material supply passageway 52 which communicates with the supply chamber.
  • a thumb knockout pin 54 may optionally be provided on the dispensing member.
  • the cylinder 14 has a second lateral aperture 56 through which extends the thumb knockout pin 54.
  • An air tight seal 58 is provided over the back of member 10 to prevent leakage of compressed air, to seal the supply passageway 52, to protect the .product contained in the supply chamber from contamination and to retain the product therein.
  • the air flow path-which begins at the passageway 39 is normally blocked by solid, breakable diaphragm member 60 which is preferably seated in a recessed region of the dispensing member 10 in coaxial relationship with lateral opening 40.
  • the diaphragm member may be constructed of paper, plastic or the like and fits snugly within the recess to block the compressed air flow path.
  • the diaphragm member initially acts, in combination with the partition member 24, as an end of a compression chamber; the other end being formed member is broken, compressed air surges through passageway 39 and into the Venturi nozzle 42 and the material in supply chamber 45 is aspirated therefrom and dispensed through theVenturi nozzle 42.
  • the memberlO contains a single dose of product and may be removed, for instanceby pressing the thumb knockout pin 54, from the dispenser and a new capsule may be coupled thereto in preparation'for the next dispensing operation.
  • the piston 16, upon release, returns to its initial position due to the force exerted by the spring 32.
  • a single dose replaceable product supply dispensing device comprising: I v a piston-cylinder means having a movable member and a fixed member having a compressed air flow path therethrough with an aperture at thelend remote from said movable member;
  • a single dose replaceable product dispensing member having a product dispensing aperture and adapted to be operatively connected to said fixed member and having a compressed air fiow path therethrough, said fiow path being operatively positioned relative to said compressed air flow path of said piston-cylinder means when said product dispensing member is connected to said fixed member for communication therebetween, said dispensing member further having a product supply chamber, and aspirating means in said compressed air flow path communicating with said product supply chamber for dispensing said product via said product dispensing aperture;
