Definitions

  • This invention generally relates to dispensing devices and more particularly to a new and improved dispensing device for dispensing fluent products by gaseous pressure.
  • a separate receptacle to hold the liquid propellant is positioned within the product container.
  • Small apertures in the receptacle permit the gas developed by the liquid propellant to boil 011 and create sufficient pressure to dispense the product.
  • the liquid propellant comes into contact with the small apertures resulting in leakage and clogging.
  • a still further object of the invention is to provide a dispensing container of such construction that the small apertures, communicating the gaseous pressure with the product to be dispensed are kept from contact by the liquid propellant.
  • the invention provides a container for dispensing through a valve a fluent product under the pressure of a vaporized liquid propellant.
  • a separate receptacle maintains the liquid propellant out of contact with the fluent product while small apertures permit the gaseous pressure developed by the liquid propellant to pass into the product container for dispensing the product.
  • the structure embodying these small apertures is of such unique configuration as to prevent the liquid propellant from coming into contact with the apertures regardless of the tilt of the container.
  • the numeral 1 indicates generally a can or container of metal or other rigid material.
  • the shape of the container 1 may be of any de sired configuration, it being understood that the invention is not limited to a particular container.
  • a conventional dispensing valve 2 is positioned in a suitable opening in the upper portion of the container 1. Extending from an inlet tube 4 to the valve 2, a tube 3 of any suitable material communicates the valve 2 with the lowermost extremities of the container 1.
  • a receptacle 6 Secured to the tube 3 by means of ties or hands 5 is a receptacle 6 having a closed lower end and an open upper end, which upper end is sealed by means of a plug 7 forming a push fit. Passing through the center of the plug 7 and integral therewith is a tube 8 sealed at both ends with the exception of small pin holes identified by the numerals 9 and 10 formed in the upper and lower ends, respectively,
  • the diameter of the pin hole or holes 9 is at least as great as that of the pin hole or holes 10.
  • the metal can or container 1 contains a fluent or creamlike product 11 such as, for example, toothpaste while the receptacle 6 contains a liquid propellant 12 constituted by, for example, a halogenated hydrocarbon.
  • the device is assembled and filled with the product 11 and the propellant 12 in a manner now to be described.
  • the open container 1 is filled to the desired degree with the product 11.
  • the open receptacle 6 is secured by the ties 5 to the tube 3 which tube 3, in turn, is fitted on the inlet tube 4 of the valve 2.
  • a liquid propellant 12 is fed into the receptacle 6 to the desired amount, the propellant being cooled well below its boiling point.
  • the receptacle 6 is then sealed by the plug 7 with the tube 8 in position and the assembled unit is positioned within the container 1.
  • the valve 2 is sealed to the container 1 as quickly as possible so as to avoid any substantial boiling off of the propellant 12.
  • the product 11 can be dispensed through an outlet 13 of the valve 2 when desired.
  • the vapor pressure above the liquid propellant 12 may be instantaneously lowered to such an extent that the liquid propellant 12 in the receptacle 6 begins to boil and froth. In this instance, some of the boiling liquid 12 may contact the pin hole 10 resulting in a small quantity of the liquid 12 entering the tube 8. However, the correct dimen sions of the pin holes 9 and 10 insures that none of this liquid propellant 12 which has thus succeeded in entering the tube 8 will be able to enter the product container 1.
  • any such liquid 12 which remains in the tube 8 after such inter-dispensing period described above will be volatilised eflectively during the next dispensing operation.
  • the pin hole 9 be at least as large as the pin hole 10 while not so large as to allow any of the product 11 to enter the pin hole 9 it splashed thereon.
  • the assembled receptacle 6 was contained in a receptacle 6 having aninternal volume of 13.25 ccs., thereceptacle 6 having aninternal diameterof 1.5 cms. and an internal height of 7.5 cms., the liquid propellant 12 filling the receptacle 6 to a height of 3 cms.
  • the tube 8 had an internal diameter of 0.32 cm. and a height of 3.75 cms.
  • the lower end of the tube 8v was disposed 3.75 cms. from the bottom of the receptacle 6.
  • the pin holes 9 and 10 had diameters of 0.01 inch, respectively.
  • the propellant receptacle may be disposed within the product can and may take the form of a tube sealed at both ends and provided with a side aperture over which is fitted a valve of the Bunsen type.
  • This valve can take the form of a rubber sleeve fitting tightly over the aperture in the tube and having formed in it an incision which opens up upon the development of a suiliciently strong positive pressure in the tube thereby allowing the passage of propellant vapor from the tube into the product can.
  • the degree of opening of the incision under pressure must never be sufiicient for the actual propellant liquid to escape from the tube.
  • the tube can be arranged to communicate through the Bunsen valve with a chamber which itself communicates with the product can via a further communicating valve, this latter valve being also possibly of a Bunsen type.
  • a modified form of unspillable ink-well type of receptacle may be used to contain the liquid propellant, the receptacle being weighted at the bottom and allowed to float on the surface of the product within the product can so that no matter which way the dispensing container is held the propellant receptacle is always maintained in a substantially vertical position. It should be noted, however, that such an arrangement is only satisfactory when the product is not so viscous as to prevent prompt righting of the propellant receptacle. It will be apparent that numerous modifications may readily be made to the type of propellant receptacle employed, such modifications being well within the scope of the present invention.
  • a construction in accordance with the present invention to dispense in a substantially unaltered and unfoamed form, suitable flowable products, such as toothpaste, and edible products such as, for example, salad cream.
  • suitable flowable products such as toothpaste, and edible products such as, for example, salad cream.
  • the product foamed to a limited degree, i.e. as a high density foam the product can be mixed with a specified amount of a gas under pressure such as carbon dioxide 'or nitrous oxide while the main propellant acts on-the product to ensure its uniform and substantially complete ejection.
  • a dispensing device for dispensing fluent materials by vaporous pressure having a container for enclosing the fluent material to be dispensed, a valve mounted on the container for releasing the fluent material, means to maintain the fluent material under vaporous pressure, said means comprising a receptacle disposed within the container for enclosing a liquid propellant, a tube disposed through the walls of the receptacle and extending into the receptacle a predetermined distance so that the inner end thereof is above the level of liquid propellant when said device is in any position and the outer end is in communication with said container, and said tube having an aperture at each end thereof to communicate the propellant vapor in the receptacle with the fluent material in the container.
  • a dispensing device for dispensing fluent materials by vaporous pressure having a container for enclosing the fluent material to be dispensed, a valve mounted on the container for releasing the fluent material, means to maintain the fluent material under vaporous pressure, said means comprising an open ended receptacle mounted within the container for containing a liquid propellant having a boiling point below room temperature at atmosphen'c pressure, a plug adapted to seal the open end of the receptacle, a tube disposed through the plug in sealed engagement therewith and extending into the receptacle a predetermined distance so that the inner end thereof is above the level of liquid propellant when said device is in any position and the outer end is in communication with said container, and said tube having an aperture at each end thereof to communicate the propellant vapor in the receptacle with the fluent material in the container.
  • a dispensing device wherein a separate tube means extends from the valve means within said container and the propellant receptacle is attached to the separate tube means.
  • a dispensing device according to claim 2 wherein the tube disposed through the plug extends into the propellant receptacle a distance at least equal to the height of liquid propellant contained in the receptacle.
  • a dispensing device for dispensing fluent materials by vaporous pressure comprising a container means for enclosing a fiuent material to be dispensed, value means associated with the container means for releasing the fluent material in desired quantities, receptacle means associated with the container means but positioned therein for maintaining a predetermined quantity of liquid propellant sepa rate from the fluent material.
  • tubular means extending into the receptacle means a distance greater than the height of the liquid propellant so that the inner end thereof is above the level of liquid propellant when said device is in any position and the outer end is in communication with said container, and said tubular means having an aperture at each end thereof communicat ng the space in the receptacle above the liquid propellant with the space in the container means above the fluent material.
