Definitions

  • the dispensing valves In the art of mixing and dispensing pressurized (i.e. aerosol) shaving cream, and particularly the dispensing and mixing of fluids to generate an exothermic reaction for heating the shaving cream, the dispensing valves must be small, economical, compact and yet accurate in their proportional dispensation of the respective fluids to achieve the desired degree of heating of the shave cream while minimizing any dangers of malproportioning of the fluids due to improper valve operation. Some ingredients in the fluid would be injurious to the users face if dispensed in too great a concentration in the shave cream, and if dispensed in too small a quantity the desired heating would not be achieved.
  • valves must be capable of proportional dispensing of a plurality of fluids in such a manner that the two fluids may mix before reaching the outlet of the valve so that exothermic reactions generated by the ingredients in the fluids may take place to provide a hot lather shaving material, or the like.
  • Fluids dispensing valve which are adapted, concurrently and proportionally to dispense a plurality of fluids may have difllculty in accurate proportional dispensation of a plurality of fluids, throughout a range of positions of their valve elements, from a partially open position to a fully opened position.
  • the preferable dispensing valve for the present invention is one in which the flow of fluids is not controlled by the amount by which the valve is open, but rather the valve is open or closed, and the flow of fluids is governed by orifice sizes other than the degree to which the valve is open.
  • the present invention possesses this desirable feature.
  • the present invention is not limited to applications in which a hot composition is dispensed, but is useful in dispensing cool shave cream or the like.
  • one fluid may contain some of the components for a shave cream, and the other fluid may contain the other components for the cream.
  • a superior shave cream is dispensed, or one which was impossible to generate in known shave cream dispensers due to the incompatability of the components when in a single fluid system.
  • Incompatability means inter alia, pH conditions, solubility, dispersion and the like.
  • the present invention relates to a novel fluids dispensing Valve wherein a flexible valve element is provided with opposite sides engaged by a generally annular valve seat and a generally annular poppet respectively; and wherein fluid passage communicate with opposite sides of the flexible valve element outwardly of the peripheral portions of the poppet and the valve seat, such that movement of the poppet away from the flexible valve element permits separate fluids ot flow at opposite sides of said flexible valve element at locations between said opposite sides and said respective poppet and seat.
  • such a flexible valve element with a cooperating stationary seat and movable poppet valve provides for concurrent and accurate proportional dispensation of a plurality of fluids even thou-gh the valve may be partially open or fully open.
  • the fluids dispensing valve of the invention may be very effectively used in connection with the dispensation of a plurality of ingredients as a single composition, such as may be required in exothermic reactions involving hot leather shaving cream dispensed from pressurized containers.
  • the fluid dispensing valve of the invention is very small, compact and economically producible and which may be highly desirable for use in connection with aerosol hot shave lather dispensers, or the like.
  • the fluids dispensing valve of the invention may, however, be used for a great variety of purposes which relate to concurrent proportional dispensing of a plurality of ingredients (normally fluids) by a common valve operation.
  • Another object of the invention is to provide a very simple and economical fluids dispensing valve which is particularly adapted for use in mixing a plurality of fluids and dispensing the mixed fluids as a hot shave lather.
  • Another object of the present invention is to provide a fluids dispensing valve which is particularly adapted for use in accurately and concurrently dispensing proportional amounts of materials to create an exothermic production of hot shave lather.
  • Another object of the invention is to provide a dispensing valve which is particularly adapted for use in dispensing a plurality of separate relatively reactive ingredients and to mix such -without permitting any of the mixed compositions to communicate with the separate ingredients remaining to be dispensed.
  • the reactive ingredients are dispensed or dissolved in a liquid medium and one or more of the liquid media can be pressurized for dispensing the media.
  • One of the media can be pressurized and the other media dispensed by a venturi or suction action created by dispensing the pressurized media.
  • Another object of the invention is to provide a fluids dispensing valve which may be operable either by means of a tilting nozzle structure, or by a rectilinearly reciprocating actuator.
  • Another object of the invention is to provide a novel fluids dispensing valve comprising a flexible valve element having opposite sides which are engageable respectively by a stationary seat and a moveable poppet, and wherein fluid passages communicating with said opposite sides of the flexible valve element; said passages also communicating with two fluid containers, one of which is an outer container adapted to contain pressurized fluid, and the other which is an inner container of collapsible structure, whereby both fluids are pressurized when the inner container collapses in response to fluid pressure within the outer container so that both fluids are under substantially a common pressure differential at opposite sides of the flexible valve element and so that measured dispensation of the fluids relative to each other may occur when the poppet valve member is moved away from the flexible valve element in order that the flexible valve element may seek an intermediate position between the seat and the poppet valve member.
  • Another object of the invention is to provide a novel fluids dispensing valve, wherein a plurality of fluids are concurrently dispensed in accurate proportions relative to each other, and wherein the fluids after being dispensed enter the outlet of the valve and are forced through a tortuous passage means for efficient mixing of the fluids before they finally emerge from the outlet of the valve of the invention.
