Definitions

  • FIG.3 DISPENSER WITH HEAT EXCHANGER AT ITS DISCHARGE OUTLET Filed Sept. 1, 1964 FIG.3
  • FIG. 1 A first figure.
  • This invention also relates to heat exchange devices which are especially adapted for use in the foregoing method and more particularly to a heat exchanger especially adapted for use on a dispenser of flowable substance whereby the temperature of the substance may be changed, as the substance is being dispensed, from that temperature at which the substance is contained during storage to either a higher or lower temperature which is more suitable to the end use of the substance.
  • a heat exchanger especially adapted for use on a dispenser of flowable substance whereby the temperature of the substance may be changed, as the substance is being dispensed, from that temperature at which the substance is contained during storage to either a higher or lower temperature which is more suitable to the end use of the substance.
  • the contained substance is dispensed at substantially the same temperature as that at which the container has been stored even though the substance should be or may more desirably be used or applied at a substantially different This disparity cannot be eliminated in most cases simply by storing the container at the most desirable temperature-especially not a temperature substantially above ordinary room temperaturebecause of the unsafe effect on the pressure of the aerosol propellant.
  • Numerous means are known for cooling or heating packaged or contained substances dispensed from a container so that the contents of the container or some part of it, may be delivered from the container to a utilization site at a temperature which is substantially different from the normal temperature of the container. Many of these heat the container, or some part of it, and its contents. Other means heat the dispensed substance in some reservoir outside the container itself and the'heated substance is then dispensed from the reservoir to the site of actual use. The heat is sometimes obtained from built-in chemical or electric sources; in other instances external sources of heat are utilized. None of these known means is entirely suitable for altering the temperature of substances dispensed from aerosol-type containers because of the charracteristics of containers and their contents and because of their inherent portability and manner of use.
  • our method is for changing the temperature of a flowable substance as it is dispensed from a container having an outlet and having means at the outlet for controlling the flow of substance there-through.
  • the method comprises the steps of providing an elongated conduit bounded along its length by material having substantial thermal capacity and good heat transfer characteristics.
  • the conduit is provided with an inlet in communication with the outlet of said container and is also provided with an outlet.
  • a thermal transfer substance is flowed in thermal contact with the material bounding the conduit to cause the temperature of the material to approach the temperature of the transfer substance.
  • a quantity of the flowable substance is then released from the container by means of the outlet valve and flowed through the conduit -to a utilization site beyond the outlet of the conduit.
  • a heat exchange device which is especially adapted for use in accordance with the foregoing method;
  • This heat exchange device comprises, in combination with a dispensing container for flowable substance and having means for propelling said substance from the container and further having a discharge valve for controlling the flow of substance from within said container to a region external thereto, comprises a body of material for substantial thermal capacity and good heat transfer properties, the body is provided with a tortuous conduit therethrough from an inlet connected to the discharge valve of the container to an outlet for delivering the substance to a utilization site. The external surfaces of the body are exposed.
  • the temperature of a quantity of the substance may be altered during its delivery from the container to a utilization site simply by flowing over the exposed surfaces of the body a heatable fluid at a temperature different from that of the body and then opening the discharge valve of the container to discharge substance into and through the conduit.
  • a conduit having a tortuous course in accordance with our invention permits a heating conduit of extended length to be contained in a body having a mass which is relatively large compared to the volume of the device. This enhances its convenience and efficiency.
  • the tortuous course which the conduit describes is a spiral path in a substantially cylindrical body.
  • An additional feature of our invention is a means for improving the transfer of heat from the thermal transfer substance to the heat exchanger and it comprises a shroud element fabricated of plastic or metal.
  • This shroud substantially surrounds the body of the heat exchanger and is generally spaced from it.
  • These openings are at spaced locations so that transfer substance directed into one of them is directed by the walls of the shroud around and in good thermal contact with the external surfaces of the exchanger itself before it reaches another of theopenings from whence the transfer substance may leave the shroud.
  • At least one such opening may be located in a wall of the shroud at a position diametrically opposed to the outlet of the heat exchanger conduit. At least one other such opening may be conveniently located in a wall of the shroud adjacent to the outlet of the conduit.
  • thermal transfer substance either hot or cold as may be desired, is flowed through the shroud opening located diametrically opposite the outlet of the conduit and into the space between the Walls of the shroud and the body of the heat exchanger while within the space the shroud directs the transfer substance over the external surfaces of the body of the heat exchanger to add or subtract heat and thereby raise or lower the temperature of the body.
  • the transfer substance then flows out of the space through the shroud opening adjacent the outlet of the conduit. As the flow of transfer substance continues, the temperature of the body approaches that of the transfer substance.
  • the discharge valve of the container may be actuated so that a quantity of the substance in the container is released to flow through the conduit in the heat exchanger in contact with the peripheral walls of the conduit so that heat is transferred between the body of the heat exchanger and the substance being dispensed from the container.
  • the substance emerging from the outlet of the conduit will thus be at a temperature which approaches the temperature of the transfer substance flowed over the exposed surfaces of the heat exchanger body and is then ready for use.
  • FIG. 1 is a front elevation of a shrouded heat exchanger in accordance with the invention and mounted directly on an aerosol-type container-dispenser.
  • FIG. 2 is a plan view of the shrouded heat exchanger shown in FIG. 1.
  • FIG. 3 is a rear elevation of the shroud heat exchanger shown in FIG. 1.
  • FIG. 4 is an enlarged sectional view, taken along the line 44 of FIG. 2, of the shrouded heat exchanger shown in FIGS. 1-3.
  • FIG. 5 is an enlarged sectional view taken along the line 55 of FIG. 4.
  • FIGS. 1, 2 and 3 we illustrate a conventional aerosol-type container-dispenser of, for example, shaving lather.
  • Shaving lather which is packaged in this form has achieved great popularity in recent years. It has achieved this popularity even though, contrary to the dictates of long standing tradition and maximum comfort, it has had to be applied to the users face at room tem perature, which is the temperature usually assumed by the container.
  • aerosol-type contamer-dispensers should not be stored at or subjected to even moderately elevated temperatures for a time that would be long enough to raise the temperature of the shaving lather in the container substantially above room temperature.
  • the heat exchanger device we have invented makes it possible for the first time to quickly and easily dispense from an aerosol container-dispenser a quantity of heated shaving lather sufficient for one shave.
  • an external heat exchanger adapted to an aerosol container-dispenser of shaving lather is operated in accordance with our new method, it is a simple matter to dispense heated shaving lather without subjecting the container itself to any increase in temperature at all.
  • a heat exchanger device is directly adapted to a conventional aerosol-type container 1.
  • a container is provided with a dispensing valve built into the top of the container and the valve is normally spring-biased to the closed position so that any suitable quantity of the lather may be dispensed from the container merely by exerting pressure on a control member, usually an exposed part of the valve outlet.
  • a control member usually an exposed part of the valve outlet.
  • Such valves are well known and in the drawing the valve outlet and control member is generally illustrated at 2.
  • the heat exchanger comprises a body 3 of material having substantial thermal capacity and good heat transfer characteristics. Suitable materials for the body of the heat exchanger are copper and aluminum, although other materials Will also serve these purposes.
  • the heat exchanger body consists of a cup-shaped member 3 and a cover member 4.
  • the bottom of the cup-shaped member 3 is provided with a central recess 5 which is proportioned to fit snugly over the valve outlet member 2.
  • This recess has an inlet aperture 6 through which shaving lather flows from the valve outlet into the body of the heat exchanger.
  • the heat exchanger body is also provided with an outlet aperture 7 in the peripheral wall of the cup 3.
  • a spout 8 which may be formed integrally with the cup leads away from the outlet aperture 7 so that shaving lather dispensed through the heat exchanger may be conveniently and neatly delivered to the hand or face of the user.
  • the body of the heat exchanger has an elongated tortuous conduit 9 extending through the body from the inlet aperture 6 to the outlet aperture 7 and spout 8.
  • the tortuous path is a spiral and the conduit is formed by a spirally'wound strip 10 of a material having the same good thermal characteristics as the material from which the cup 3 is formed, for the strip 10 combines with the cup 3 and the cover 4 to form the body of the heat exchanger.
  • the strip 10 has several characteristics each one of which contributes to the efficiency of operation of the heat exchanger as a whole.
  • the strip is wound with several turns so that the innermost turn terminates adjacent the inlet aperture 6 and is braced against the recess 5. From there each turn of the strip is generally spaced from the next innermost turn by a progressively greater distance so that the cross sectional area of the conduit formed by the combination of the spirally wound strip 10, the bottom wall of the cup 3 and the cover member 4 increases from the inlet 6 to the outlet 7.
  • the width of the spiralv strip is equal to the depth of the cup 3 between the bottom wall and the cover member 4 so that there is good thermal contact between the top and bottom of the body of the heat exchanger and the several turns of the spiral strip itself.
  • the strip is not bonded to the cup or cover in any way; therefore, a close mechanical fit between the parts is desirable to insure that heat is conducted to all parts of the strip so that it, too, absorbs heat from the transfer substance and passes the heat on the lather.
  • it is desirable to form the outer .end of the strip so that a substantial area near the end bears directly against the peripheral wall of the cup 3.
  • the cup member may be drawn from a relatively thin aluminum sheet.
  • the cover member 4 is simply stamped from a sheet of the same material and the spiral strip is wound from a strip of the same material.
  • the spiral strip need only be positioned within the cup as shown in FIG. 5 and it is generally not necessary to fasten it in place for the natural tendency of the spiral to expand will usually result in a frictional fit between the outer turn of the spiral and the peripheral walls of the cup which is sufficient to hold the spiral in place.
  • the cover memher 4 may be crimped to the top edges of the peripheral walls of the cup as illustrated :at 11 in FIG. 4.
  • the heat exchanger described above together with a conventional aerosol container-dispenser, is sufiicient in and of itself to perform in accordance with the invention.
  • a quantity of shaving lather may be dispensed from the container and heated by the following simple method.
  • the heat exchanger is held for a short While in any convenient heated substance, in for example, a stream of hot water from a household faucet, until the temperature of the cup 3, the cover member 4 and the spiral strip 10 have been raised to approximately the temperature of the water or other substance.
  • the heat exchanger is then removed from the hot water whereupon it is only necessary to actuate the discharge valve of the container so that shaving lather is propelled from the container into the inlet 6 and through the spiral conduit of the heat exchanger to the outlet aperture 7 and then through the spout 8.
  • the lather As the lather emerges from the outlet member of the discharge valve, it immediately expands to fill the cross section of the spiral conduit and it begins to absorb heat from the surfaces bounding the conduit, namely, the bottom of the cup 3, the cover member 4 and the spiral strip 10.
  • that part of the lather which first entered the heat exchanger is propelled along the spiral conduit and it continues to absorb heat.
  • the heat exchanger having approximately the portions shown in the drawing can, in about 10 seconds, readily absorb enough heat from water at 160 F. to raise by about 25 F. the temperature of a quantity of shaving lather sufiicient for one shave. This increase in temperature of the shaving lather gives that very pleasant sensation which users of aerosol shaving lather will recall from their last shave by a barber.
  • the heated lather also has a markedly improved action during the course of the shave.
  • the bare heat exchange device we have described above performs extremely well. However, it is inevitable that a stream of running water from a household faucet, for example, will tend to splash off the upstream surfaces of the exchanger and contact the downstream surfaces only intermittently, thus requiring that the heat exchange device be held in the stream for a longer time before the entire body of the device approaches the temperature of the water. Therefore, in the preferred embodiment of the invention we provide a shroud 13 for the heat exchange device. As shown in FIGS. 1-4, the shroud surrounds the device and is generally spaced from it. There is an inlet aperture 14 in the wall of the shroud and a diametrically opposite outlet aperture 15 through which the outlet spout 8 protrudes.
  • the bottom of the shroud is open and is provided with a suitable mounting collar 16 which is adapted to fit over the top of the container-dispenser.
  • a suitable mounting collar 16 which is adapted to fit over the top of the container-dispenser.
  • the shroud may be formed of any suitable material such as molded synthetic resin.
  • the heat transfer properties of the shroud itself are immaterial to the functioning of the heat exchanger, although a material having a relatively low specific heat will remove less heat from the water which is intended, after all, to heat the device within the shroud.
  • the use of a shroud material having low specific heat also acts as a thermal insulator to protect the user against direct contact with the heat exchange device which may become uncomfortably warm.
  • a trigger member for indirectly actuating the discharge valve of the container may be molded as an integral part of a plastic shroud provided only that the cured resin has some slight elasticity.
  • a portion 16 of the top of the shroud is separated from the main body of the shroud along the rear and side edges 17 and 18 and is only attached along the front edge 20.
  • This line of attachment acts as an elastic hinge so that the trigger member ;16, although an integral part of the shroud, may move up and down through at least a small angle as indicated by the arrows at 21.
  • digital pressure exerted on the trigger member will actuate the discharge valve of the container, for the pressure on the trigger is transmitted through the stud 22 to the body of the heat exchanger and then to the control member 2 of the discharge valve.
  • the preferred embodiment of our invention is quite efiicient from the thermodynamic point of view. It is also compact and readily adaptable to the valves and contours of conventional aerosol-type container-dispensers. It will, however, be apparent to those skilled in the art that a heat exchanger according to our invention may be embodied in many different forms. For example, a channel having a tortuous path may be embossed or drawn into a metal plate and a second metal plate, either flat or having a reciprocally shaped channel therein, may be used to close the channel to form a conduit in accordance with the invention.
  • a heat exchange device in combination with a dispensing container for flowable substance, said container having control means having an outlet for controlling the flow of substance from within said container to a region external thereto, which heat exchange device comprises (a) a cup-shaped member having a bottom wall and peripheral side walls defining a cavity therein and being formed of material having substantial thermal capacity and good heat transfer properties, the external surfaces of said cup-shaped member being exposed,
  • a channel member consisting of a spirally formed plate, with its upper and lower edges in good thermal contact, respectively, with said closure and bottom wall, and its terminal portion in good thermal contact with said peripheral side walls, said channel member, together with said cup-shaped member and said closure member forming a single elongated conduit,
  • a heat exchange device in combination with a dispensing container for flowable substance said container having control means having an outlet for controlling the flow of substance from within said container to a region external thereto, which heat exchange device comprises 1 (a) a cup-shaped member having a bottom wall and peripheral side walls defining a cavity therein and being formed of material having substantial thermal capacity and good heat transfer properties, the external surfaces of said cup-shaped member being exposed,

  • a heat exchange device in combination with a dispensing container for flowable substance said container having control means having an outlet for controlling the 8 flow of substance from within said container to a region external thereto, which heat exchange device comprises (a) a body of material having substantial thermal capacity and good heat transfer properties,
  • said body having a tortuous conduit therethrough and said conduit having an inlet connected to the outlet of the control means and also having an outlet for delivering the substance to a utilization site,
