  • a second button 135 formed of magnetically attractable material.
  • the magnetically attractable button 135 engages the underside of the bottom wall portion 136 in the well 127, due to the attraction of the magnet 24 which is shown in solid lines positioned directly over the button 135.
  • the switch blade 128, due to its natural resilience, moves to the position shown in phantom lines, separating the contacts 130 and 13-1 to interrupt the circuit between the terminals 115 and 132 and the flow of power applied to the heating means 16.
  • Suitable means is provided to shift the magnet 24 between the off and on positions which positions may be labeled by means of suitable indicia.

  • the switch cover plate 26 has an axially projecting flange 143 which is interfitted within and adhesively joined to the axially directed flange 125 and serves to align the opening 27 in the cover plate with the opening 124 in the center of the wall 123.
  • the clear plastic lens 28 When the clear plastic lens 28 is inserted, it is aligned with the lamp 110 which is positioned in alignment with the opening 124 where it may be easily seen through the lens 28.

Since the bi-metallic element in the thermal switch is cold, the heater contacts 102 and 103 are in the engaged or conducting condition shown in FIG. 3, completing the circuit through the resistance element 83 and causing it to heat. Heat from the shell 80 is transferred to the heat exchanger 18 through the cover plate 76 to the individual spirals on the heat exchange element 74 to elevate the temperature.
  • the contacts 102 and 103 are automatically broken by the button 99 on the bi-metallic element on the thermal switch and the indicating lamp 110* will be illuminated and dispensing may commence. Light downward force may be applied to the cover plate 26 causing the nozzle 65 to move inwardly of the aerosol container 13 to release the contents.
  • the valve arrangement of the container 13 consists of a plunger element 160 formed integral with the nozzle 65.
  • a biasing spring 161 urges the plunger 160 to seat against the top wall 162 to preclude the passage'of fluid out the nozzle 65, however, when the nozzle 65 is depressed, a lateral opening 163 formed in the tubular nozzle 65 is moved past the fixed valve seat 162 permitting communication through the flexible hose 164 which extends to the bottom 165 of the container 13. Fluid may then pass through the hose 164, the spring 161, around the plunger 160 and out the opening 163 into the heat exchanger, where it is expanded into a foam which is continuously forced around the spirally wound heat exchange element to take on heat. As more fluid is released, the heated foam is continuously emitted from the outlet opening through the nozzle 40 where it may be applied to the shavers face in a known manner.
  • valve nozzle 65 and integral plunger are of plastic material which will melt at 500-700 F. This temperature will be reached by the valve well in advance of overheating of the container inasmuch as the nozzle 65 ac tually touches the heat exchanger.
  • the entire dispenser will drop, continue its downward travel until the ends of the guides 43- 46 and an inwardly projecting ledge 47 at the junction of the shells 11 and 12 engage the top of the container base 14. 1f the melting has caused failure of the valve the pressurized product will be released from the containenln the absence of the stops or the failure to engage the base to arrest downward movement to maintain the container 13 and heat exchanger separated, the valve housing 167 in the container being disposed above the outer rim 168 engages the heat exchanger 18 as the nozzle 65 melts to cause further melting of the valve plunger 160 releasing the pressurized product and alleviating any danger.
  • FIG. 11 a modified form of the invention is illustrated with portions of the shell broken away to show the aerosol-type container and attached base in full elevation.
  • the construction Shown in FIGS. 11 and 12 is similar to the dispensing arrangement shown previously and the housing 200, switch 201, switch plate 202, and lens 303 may be identical to those previously described.
  • the housing 200 contains a heating means (not shown) and heat exchanger 204 mounted by a bracket 220' to a mounting ring 205.
  • the mounting ring 205 is substantially identical to the mounting ring shown in the embodiment of FIGS. l-l O with the exception that it is formed with an axially facing spring seat shoulder 206 on the underside portion.
  • the shell sections 211 and 212 are also similar to the shell sections 11 and 12 except that each is provided with an inwardly projecting flange 207 forming a stop for an annular washer 208 in addition to being slightly greater in over-all length.
  • a coil spring 210 has one end received around the circumferential spring guide flange 221 and is bottomed against the spring seat shoulder 206. The opposite end of the spring 210 is in engagement with the washer 208 and includes a centering flange 222.
  • the radial flange 207 retains the spring 210 and washer 208 within the shell 211 and 212 when aerosoltype container 213 is withdrawn by unlocking the base 214 from the shells in the mannerdescribed previously.
  • the washer 208 has an inside diameter 215 which is greater than the diameter of the upper neck 216 of the aerosol-type container but less than the over-all diameter of the body so that the washer seats on the frustoconical surface 217 joining the upper neck 216 and the main body of the aerosol-type container 213..
  • the force developed by the spring 210 is suflicient to maintain the nozzle 218 on the aerosol-type container spaced from the heat exchanger 204 in the absence of external force thus preventing any heat transfer through the nozzle to the container proper.
  • the thermostatically operated heating unit will be set for a maximum temperature which will be suitable for shaving but well below the upper design limits of the aerosoltype container 213 so heat transfer normally is not a problem, however, the spaced arrangement protects against this.
  • downward force is applied to the switch plate 202 causing the nozzle 218 to'enter an opening 220 in the heat exchanger 204.
  • the downward force must be of suflicient magnitude to overcome the combined force effects on the spring 210 and the valve spring (not shown) which is carried internally of the aerosol-type container.
  • the spring 210 returns the dispenser and aerosol-type container to the relative condition shown in FIG. 11, and the valve spring cuts ofi product flow in a well known manner.
  • the spacing between the heat exchanger 204 and the nozzle 218 of the aerosoltype container 213 is sufiicient to prevent heat transfer to the latter. Since the only available heat path is through the shoulder 206, spring 210 and inner diameter of the washer 208, direct heating of the container 213 is possible. Should heat transfer through the spring present a problem, a second flange may be formed integral with the shells 211 and 212 above the flange 207 to provide a longer heat path. In such event, the mounting ring 17 of FIG. 1 may be used in the embodiment of FIGS. 11 and 12.
  • the shoulder 207 arrests the downward travel of the washer 208 maintaining the spring tensioned slightly.

  • the inner construction of the container base 13 is similar to that illustrated in FIG. 3, having flanges 233 and 234 for interlocking wtih the flange 240 the shell sections 241 embracing the aerosol container 235.
  • the container 235 is provided with a concave bottom 236 like that illustrated in the embodiment of FIG. 3, however, the bottom of the container base 230 in FIG. 13 is thickened to engage the concave bottom 236.
  • This change in shape is suflicient to increase the over-all dimension of the container 13 so that the lugs 233 and 234 engage the lower flange 240 on the shell sections 241 and the now convex bottom 236 reacts against the base 230 to press the nozzle against the heat exchanger (not shown).
  • the bottom 236 assumes a convex shape, the seam at the margin of the can slides upwardly in the groove 242 and the nozzle of the container 235 is depressed to release the pressurized product and eliminate the hazard.

  • an attractive compact dispenser is provided which is economical to produce and sufficiently rugged to endure the expected abuse.
  • Changing of the aerosol-type container may be accomplished with unequaled ease by merely twisting the base about one-fourth of a turn to permit the lugs 57-60 to travel down the slots 51-54.
  • the aerosoltype container does not need any special adapter since the conventional nozzle normally supplied with each is fiuidtightly received in the opening 70 in the heat exchanger.
  • said aerosol container having a depressible nozzle portion which operates a valve to release the product from said container
