  • This invention relates to pressurized, hand-held dispensers, and more particularly to mixing dispensers of this type having inner and outer containers wherein several different liquids, normally isolated in the dispenser, are mixed during the discharge operation to produce specific results such as heated shaving lather,
  • a collapsible inner container whose walls are subjected to collapsing pressures by another kind of liquid (usually pressurized by a propellant) disposed in the space between the inner and outer container walls.
  • the collapsible inner container has a neck through which its contents are discharged, said neck being pressed onto an inward projecting nipple of a valve housing that is located in the outlet opening of the outer dispenser container or can for the purpose of controlling the dispensing.
  • a related object of the invention is to provide an improved multicontainer mixing dispenser as above set forth, wherein the failure-resistant connection is especially simple, easily effected, and economical to produce.
  • the inner container is still provided with a neck portion that is slipped over a tubular downward extension or nipple of the valve housing, but the said nipple is extended a greater distance, so as to project into the inner container past the neck thereof an appreciable amount.
  • a hollow retainer cap within the inner container, so as to securely maintain the neck thereof on the nipple, said cap having a through passage to enable liquid from the inner container to pass out through the nipple in the usual or required manner.
  • the hollow cap is preferably molded of plastic substance similar to that of the valve housing, and in the illustrated embodiments of the invention is provided with a deep annular groove or recess which is concentric with a central bore, said recess being adapted to receive and securely grip the projecting or terminal portion of the nipple that is located within the inner container.
  • the retainer cap is slightly tapered so that the initial engagement of the parts is easily effected.
  • the hollow cap is double ended, that is, identical at its two ends whereby either end may be applied to the projecting or terminal portion of the nipple. Also, cooperable annular beads and grooves are provided on the nipple and cap to obtain an interlocking effect by which the retention is still more securely effected.
  • FIG. 1 is an axial sectional view of a mixing-type dispenser embodying the invention, the parts being shown in the non-discharging condition.
  • FIG. 2 is a top plan view of the retainer cap of the dispenser.
  • FIG. 3 is a botton plan view of the retainer cap.
  • FIG. 4 is a fragmentary axial sectional view illustrating another embodiment of the invention, wherein the retainer cap is double-ended and wherein the cap and nipple are provided with interlocking annular bead and groove formations to render more secure the attachment of the cap to the nipple.
  • the present improved mixing dispenser comprises a relatively rigid, metal outer container or can 10 of a usual type, having a top shoulder 12 and neck portion 14, the latter being spanned by a usual type of metal mounting cup 16.
  • the cup 16 has a raised central portion 18 of inverted cup-like configuration, provided with a central opening 20 in its transverse or top wall, the said opening having an upwardly drifted edge 22 and being of a size to slidably receive a vertical valve stem designated generally by the numeral 24.
  • a tubular molded plastic valve housing 26 having a stepped central bore 28, and having at its upper end an annular exterior mounting flange 30 which is snugly received in the portion 18 of the mounting cup, and is retained therein by inwardly offset portions 32 of the cup.
  • a resilient diaphragm or valve washer 36 Clamped between the top wall 34 of the cup portion 18 and the upper end of the valve housing 26 is a resilient diaphragm or valve washer 36, having a central opening through which the valve stem 24 extends.
  • the upper portion of the valve stem 24 carries a usual type of depress button 38 having a discharge nozzle 40, said button being guided in a stationary body 42 attached to the upper portion of the container 10.
  • valve stem 24 and housing 26 with the valve washer or seat 36 are so consituted as to comprise a dual mixing valve including a positive shut-off poppet whereby, in conjunction with a flexible and collapsible tube or compartment provided in the container 10, there is effected in the housing 26 either a separation or else a mixing of two liquids, one from the container contents and the other from the enclosed compartment or tube.
  • the flexible and collapsible compartment or tube is designated 44 and has a neck portion 46 which is disposed around the lower reduced-diameter or nipple portion 27 of the valve housing 26 so that the bore 28 of the nipple communicates with the interior of the tube 44.
  • the contents of the container 44 and. must of necessity be kept effectively isolated at all times. During non-use of the dispenser this can be done by means of a simple slide-type valve.
  • valve washer 36 Cooperable with the valve washer 36 is an annular exterior shoulder or poppet portion 48 provided intermediate the ends of the valve stem 24, said stem having an upper portion 50 of tubular configuration located above the shoulder 48, and having a side passage 52 in the wall of the portion 50, immediately adjacent the valve shoulder.
  • a valve return spring 54 engages the shoulder 48 and also an interior annular shoulder 56 in the valve housing, thereby to bias the valve stem 24 upward as viewed in FIG. 1, maintaining the shoulder 48 in engagement with the valve washer 36 whereby the valve is closed, preventing egress of the contents of the container 10 and tube 44.
  • Adjoining the shoulder 56 in the valve housing 26 is an annular valve seat or slide-valve portion in the form of an integral bead 58, which is engageable with a lower cylindrical slide valve or portion 60 of the valve stem 24, thereby to close off the bore of the valve housing at said point and prevent passage of liquid upward from the flexible tube 44.
  • the valve stem 24 has a side depression 62 located above the cylindrical slide valve portion 60 as seen in FIG. 1, which is adapted to be disposed within the annular valve seat or bead 58 when the valve stern is depressed or forced inward as illustrated in FIG. 2.
  • the side passage 52 of the tubular portion 50 of the valve stern 24 will be disposed within the valve housing 26, and accordingly a passage is thus provided whereby the contents of the flexible tube 44 can be discharged upward through the housing 26, past the lower portion of the valve stem 24, inwardly through the side passage 52 thereof and up through the tubular upper portion 50 of the stem, to be discharged from the nozzle portion 40 of the depress button 38.
  • the valve housing 26 also has a side passage 62a carrying a dip tube 66 by which communication is established between the interior of the container 10 and the interior of the valve housing 26. Accordingly, when the valve stem 24 is depressed, the contents of the container 10 may also be discharged, such contents flowing inward through the tube 66 and side passage 62a into the interior of the valve housing 26 and (at such location) mixing with the liquid which is flowing upward from the flexible tube 44.
  • the flexible tube 44 may contain hydrogen peroxide.
  • a lathering mixture may be provided in the container 10, made up of various ingredients.
  • Such lathering mixture in addition to soaping, foaming and softening agents, may contain as an example sodium hypophosphite; or instead it may contain potassium sulfite.
  • Such substances when mixing with the hydrogen peroxide flowing upward from the flexible tube 44, causes a chemical reaction which results in an exothermic non-explosive decomposition of the hydrogen peroxide whereby heat is produced and supplied to the mixture so that the discharge from the nozzle 40 of the depress button 38 is in the form of a heated foam or lather.
  • the contents of the container 10 may be pressurized by the addition of any suitable non-reactive, pressurizing agent, as for example a 40/60 mixture of dichlorofluoromethane and symmetrical dichlorotetratluoroethane.
  • suitable non-reactive, pressurizing agent as for example a 40/60 mixture of dichlorofluoromethane and symmetrical dichlorotetratluoroethane.
  • Other propellant substances may be used, as well, their use being well known in the art.
  • the contents of the container 10 will effect a pressurizing of the same, and such pressure will be transmitted to the flexible tube 44, causing a collapsing action of the same and effecting an internal pressure to which the hydrogen peroxide in the tube if subjected.
  • the valve stem 24 is depressed as illustrated in FIG. 2
  • the pressurized liquids in the container 10 and tube 44 will result in the contents thereof being discharged through the valve housing 26, upper valve stem portion 50 and discharge nozzle 40.
  • the neck portion 46 of the inner container or tube 44 has an external annular flange 70 which provides a certain amount of reinforcement and strengthening, thereby tending to maintain the neck portion properly positioned on the nipple 27.
  • the neck portion 46 due to various factors it is possible for the neck portion 46 to become sufficiently loose around the nipple 27 that not only will leakage occur from or into the tube 84 but also it is possible for the tube 44 (specifically the neck portion 46 thereof) to be entirely dislodged from the nipple 27, .thereby rendering the dispenser wholly inoperative for the desired purpose.
  • the neck portion 46 on the nipple 27 is increased in length, so as to have a terminal portion 72 which projects inward into the tube 44 and well past the neck portion 46 thereof.
  • a hollow retainer cap 74 having a central bore 76, a transverse bottom wall 78, an annular outer wall 80 and concentric annular inner wall 82. Between the annular walls 80, 82 there is formed a deep annular recess or groove 84 which is adapted to frictionally receive the lower or terminal portion 72 of the nipple 27.
  • the hollow cap 74 is so constructed that a tight frictional fit is had between the cap and the terminal portion 72 of the nipple.
  • the cap 74 will thereby be securely retained in place, and will effectively and reliably maintain the neck portion 46 of the tube 44 against dislodgement.
  • the cap 74 constitutes an effective seal to prevent leakage.
  • the nipple 27 is provided with an external annular shoulder 86 against which the end or rim of the neck 46 is positioned. When the cap 74 is pressed on the nipple, it will force the neck 46 against the shoulder 86 and maintain it in tight sealing engagement therewith whereby leakage of contents between the inner and outer containers is effectively prevented.
  • the terminal portion 72 of the nipple 27 has a tapered outer wall surface 88 which helps locate the nipple in the annular groove 84 and also enables the parts to be proportioned for a tighter frictional fit.
  • FIG. 4 Another embodiment of the invention is illustrated in FIG. 4, wherein a nipple 27a having a bore 28a and tapered terminal portion 72a is provided with an annular detent bead 90 to be interlockingly received in an annular groove 92 of a hollow cap 74a.
  • the cap 74a is of the double-ended type, that is, one end is identical to the other.
  • the cap 74a has a central bore 76a, an annular outer wall 80a and an annular inner wall 82a, said walls being joined by an annular web portion or transverse wall 78a.
  • the wall 78a is disposed intermediate the ends of the cap 74a, as distinguished from its bottom disposition in the cap 74 of FIGS. 1-3.
  • the double-ended retainer cap 74a has two annular recesses 84a and 94a, which are of identical size and configuration.
  • the outer wall 80a of the cap has a second annular groove 960 which can cooperate with the annular bead 90a if the cap 74a should be reversed end for end prior to being applied to the nipple 27a.
  • the retainer cap is seen to be of especially simple construction whereby it can be economically molded in simple cavities, of suitable plastic substance.
  • the cap can be applied through the bore of the inner container or tube 44 prior to the bottom end of the latter being closed, this being usually effected by a heat-sealing operation.
  • an outer container adapted to carry a pressurized liquid product, said outer container having an outlet opening,
  • means including a valve housing disposed in the outlet opening of the outer container for closing the same, said valve housing having a chamber and a pair of inlet passages communicating with the chamber, and said valve housing further having a projecting nipple with a bore, constituting one of said inlet passages,
  • a collapsible inner container for holding liquid said inner container being located within the outer container and being adapted to be pressurized by the pressure of the latter,
  • said inner container having a tubular neck surrounding and press fitted to said nipple and joining the inner container thereto,
  • said nipple extending into the inner container past the neck thereof and having its terminal portion projecting within the inner container
  • a hollow retainer cap attached and press-fitted to said projecting terminal portion of the nipple within the inner container to thereby lock and retain the inner container and the neck thereof on the nipple, said cap having a through passage to enable liquid from the inner container to pass out through the nipple.
  • the retainer cap comprises inner and outer, concentric annular walls spaced apart by an annular recess in which the terminal portion of the nipple is received,
  • the terminal portion of saidnipple is tapered to facilitate its entry in said annular recess.
  • the retainer cap has a transverse, apertured wall at one end thereof, disposed adjacent the edge of the nipple terminal portion.
  • the retainer cap has a transverse apertured wall intermediate the ends thereof, disposed adjacent the edge of the nipple terminal portion.
