Definitions

  • a discharge spout unit on one of said members operatively connected to both members is adapted to dispense the mixed contents of both containers, whereby the contents are simultaneously discharged from both containers, mixed and dispensed from the spout unit when said cooperating structure is associated in said second dispensing position and the members and their respective containers have been moved toward each other.
  • the containers may for example contain respectively fluid shave cream and a material adapted for exothermic interaction therewith for dispensing self-heated warm lather from the discharge spout.
  • the invention relates primarily to a package including a special connecting device for the simultaneous dispensing and mixing of ingredients from two aerosol-type containers.
  • a particular application is the production of warm shave cream lather by the exothermic interaction of a shave cream containing a sulflte dispensed from one container and an oxidizing agent such as hydrogen peroxide dispensed from another container into a mixing chamber section of a common discharge member.
  • the present invention provides a connecting device that may be used for the same purposes as any hitherto proposed. It is of novel construction consisting essentially of two relatively movable members each adapted for releasable connection to a discharge valve stem of a disposable aerosol container of conventional construction. The valve stems are automatically connected to a mixing chamber section of a discharge spout unit and they remain so connected as the members and respective associated containers undergo relative movement during dispensing.

  • FIG. 16 is a fragmentary plan view showing a modified slotshape.
  • the invention comprises a novel assembly wherein opposed containers 11 and 12 of the aerosol-type are interconnected through a connecting device indicated at 13 to provide for comingled discharge of their contents.
  • Container 11 is of the usual type having an axially project ing depressible hollow discharge stem 14 which when depressed into the container actuates an internal valve to discharge the container contents through bore 15.
  • container 12 is of the usual type having an axially depressible hollow discharge stem 16 which when depressed into the con' tainer actuates an internal valve to discharge the container contents through bore 17.
  • Valve stems l4 and 16 are associated within their respective containers with suitable discharge valves (not shown) that are preferably of the type disclosed in Ablaplanalp U.S. Pat. No. 2,631,812 dated Mar. 17, I953.
  • Containers 11 and 12 are formed adjacent their discharge ends with rounded annular beads 18 and 19 respectively, such being conventional structure.
  • Connecting device 13 is preferably a two part assembly consisting of integral molded plastic members 21 and 22.
  • Member 21 comprises a transverse annular top wall 23 from the outer periphery of which depends at right angles a cylindrical outer skirt 24. At the inner periphery of wall 23 depends at right angles an inner cylindrical skirt 25 that is inturned at its lower end to form a continuous flange 26 adapted to fit under container bead 18.
  • the material of skirt 25 is of such inherent resiliency and the inclined lower edge 27 of flange 26 is such that, when member 21 is forced axially onto the top of container 11, flange 26 will resiliently cam over and slip under bead 18 to retain member 21 on container 11.
  • the outer skirt 24 is preferably of such axial length that its tapered lower edge 28 fits snugly with the container wall as shown in FIG. 2. Thus member 21 is axially releasably attached to container 11.
  • the top wall 23 is formed with a plurality of identical parallel edge arcuate slots 31.
  • Four equally circumferentially spaced slots 31 are shown, and the radially inner edge of each slot at a corresponding end is recessed inwardly at 32 to define a region of enlarged width.
  • slots 31, which are of uniform width except at region 32; are preferably concentric with the centers of skirts 24 and 25 indicated at 30 in FIG. 8.
  • a relatively short lug 33 projects upwardly from wall 23 at the inner edge of each enlarged slot region at 32.
  • slots 31 are about 45 in arcuate extent, although this is not critical.
  • Member 22 comprises an annular transverse wall 34 that has around its inner periphery an upstanding right-angle cylindrical inner skirt 35 that is inturned along its upper edge to define a flange 36 having an inclined camming surface 37.
  • flange 36 cams over the rounded bead 19 to snap fit under bead l9 and thereby axially releasably attach member 22 to container 12.
  • the diameter of inner skirt 35 is preferably about the same as that of inner skirt 25 of member 21.
  • the inner and outer skirts of each member are concentric.
  • wall 34 At its outer periphery wall 34 is formed with an upstanding cylindrical outer skirt 38 preferably having about the same diameter as outer skirt 24 of member 21. As shown in FIG. 4, wall 34 and skirt 38 are cut out to form a series of equally circumferentially spaced edge recesses 39, and depending from the inner edge of each recess 39 is a rectangular cross section leg 41, There are four legs 41, one for each slot 31 in the lower element.
  • Legs 41 are parallel to each other and extend at right angles to wall 34.
  • the lower end of each leg 41 see FIG. '7, is formed on its inner side with a downwardly facing flat ledge 42.
  • Each leg is formed on its outer side a small distance below ledge 42 with an upwardly facing flat ledge 43.
  • Preferably the lower end of each leg is beveled inwardly from just below ledge 43 as shown at 44.
  • the distance d between flat parallel ledges 42 and 43 is about equal to or preferably slightly greater than the thickness of wall 34.
  • Each leg between ledges 42 and 43 has a reduced section 40 sized to the radial width of slot 31.
  • the legs above ledge 42 have a radial width equal to the enlarged slot sections 32.
  • wall 34 is formed with a relatively wide radial edge slot 45 (FIG. 5) which at its outer end (FIG. 3) extends up into skirt 38 to form a downwardly open recess 46 therein. At its inner end slot 45 extends up into inner skirt 35 to form the axially slotted region 47 therein.
  • a hollow discharge spout unit 51 having a rigid inlet structure 50 centrally within member 22 projects from the interior of element 22 radially outwardly through the space provided by slot 45 and, as shown in FIG. 5 its upper edge is integrally joined to skirt 38 at the upper edge of recess 46,, the juncture being indicated at 52 in FIG. 6.
  • the outer end of spout 51 is beveled at 53 for flow direction control.
  • the inlet 51 is formed with upwardly and downwardly extending hollow bosses 54 and 55 provided with oppositely open bores 56 and 57 that are interconnected by a common coaxial passage 58 that is intersected at right angles by the discharge passage 59 through the spout.
  • Passage 58 is effectively a mixing chamber wherein the ingredients of the respective containers Intermix turbulently.
  • valve stems 14 and 16 respectively fit snugly into adapter bores 57 and 56 for end abutment with the bottom of these bores in the assembly, with their open ends aligned with passage 58.
  • the containers 11 and 12 are placed in assembly interconnected by device 13 by pushing them axially into the releasable retainer sockets provided by skirts 25 and 35 as shown in FIG. 2.
  • the valve stems 14 and 16 respectively will be bottomed in bores 57 and 56.
  • the flexible pivotal connection between the spout 51 and member 22 will permit the inlet end of the spout to shift to compensate for dimensional differences in the valve stems and bores.
  • the operator In order to effect discharge of the contents of the containers, the operator merely rotates the containers relatively on their common axis (as by rotating lower container 11 coun' terclockwise as shown by the arrow in FIG. as permitted by slots 31 and then pushes them toward each other when the legs 41 reach the wide regions 32 of the slots. During this turning movement ledges 42 and 43 slide along the opposite surfaces of wall 34 and prevent relative tilting of the members while retaining them in axial assembly.
  • FIGS. 10 and 12 show the relationship of parts when the legs have been disposed in the wide parts of the slots. While ledges 43 remain in slidable contact with undersurface 62 of wall 34, to prevent axial separation of members 21 and 22, ledges 42 are now clear of surface 61 and disposed above the wide region of the slot. It will be noted that lugs 33 abut the rear sides of legs 41 to prevent legs 41 from moving radially inwardly when the legs reach the FIG. 10 position, which insures that ledges 42 will be maintained clear of the top surface of wall 34.
  • container 12 may contain an oxidizing fluid such as hydrogen peroxide under pressure which will admix with the composition in an exothermic interaction which will not change the effective properties of the shave cream but will result in discharge of warm lather from the outer end of the spout.
  • an oxidizing fluid such as hydrogen peroxide under pressure which will admix with the composition in an exothermic interaction which will not change the effective properties of the shave cream but will result in discharge of warm lather from the outer end of the spout.
  • juncture 52 constitutes the sole point of attachment of spout 51 to member 22, and thisjuncture because of the inherent flexibility of the plastic from which element 22 is molded comprises an effective resilient pivot connection between the spout 51 and member 22.
  • This pivotal connection enables the inlet end of spout 51 to accommodate and reposition itself to suit varying lengths of valve stems and eliminates the need for accurate determination of the lengths of bores 56 and 57.
  • Spout 51 will merely tilt slightly about pivot 52 to suit the interfit of the valve stems with bores 56 and 57.
  • the invention therefore provides a novel package wherein the containers are conventional and disposable and one or both may be replaced when exhausted. Assembly requires only axial thrust of the containers into the connecting device, and operation for dispensing requires only simple sequential rotary and axial movements of small extent. When the manual pressure urging the containers toward each other for dispensing is relaxed, the internal resilient means in the containers urges them apart toward nondispensing position where the device may be locked by a simple rotary movement.
  • a removable housing structure indicated at 61 in FIG. 1 is mounted to enclose upper container 12, the connecting device 13 and at least the upper part of lower container 11.
  • This housing may be of two axially separable parts 62 and 63 one of which has a slot to pass spout 51 in assembly and in operation, and the housing inner diameter indicated at 64 is sized to a sliding friction slip fit over skirts 38 and 24 and the body container 11, all of which are substantially the same diameter.
  • housing 61 With housing 61 in place the assembly may be operated for dispensing simply by pushing down on the housing which slides upon the skirts and lower container.
  • the peripheral friction fit between container 12 and the reduced upper diameter 65 of the housing is such that rotation of the housing about axis 30 rotates container 12 along with it.
  • An axially separable sliding circular joint 66 is provided between parts 62 and 63.
  • FIGS. 14-16 illustrate a further embodiment wherein there are some differences in structure and a safety device is incorporated to prevent the contents of one container from undesirably entering the other container under certain conditions such as when outlet spout 51 is blocked. It will be noted that normally no dip tube is used for container 12 since it is inverted.
  • the spout inlet structure on lower member 21 is formed above the intersection of passages 58 and 59 with a check valve toprevent undesired discharge of fluid into the interior of container 12.
  • this check valve may comprise a light weight spherical ball 71 disposed in a chamber 70 and adapted to engage an annular seat 72 to block fluid from entering the upper passage section 73. Normally ball 71 rests on ribs 74 in the lower part of chamber 70 so that the chamber is always open to passage 58.
  • plug 75 For purposes of assembly seat 72 and passage portion 73 may be formed on the lower end of a hollow plug 75 press fitted into the inlet structure into a shoulder in alignment with passage 58. Plug 75 has an internal shoulder 76 against which abuts the upper valve stem 16.
  • an outer cylindrical skirt 80 extends up from transverse wall 23 and upper member 22 is formed with an annular transverse flange 82 that is adapted to longitudinally slidably fit within the guide provided by the inner periphery 76 of skirt 74. This helps prevent relative tilting of the containers during operation.
  • Legs 41 here integrally depend from flange 82 and their lower ends are formed as in the FIG. l13 embodiment to project into and coact with slots 77 in wall 23.
  • slots 77 are the same as slots 31 illustrated for for example in FIG. 13 except that the outer arcuate edge 78 has a shoulder 79 which the leg encounters just before entering the wide region 81, so that a positive force is necessary to move the leg past shoulder 79. This prevents unintentional relative displacement of the parts to discharge position.
  • FIGS. 14I6 could be used in the embodiment of FIGS. 1-13.
  • a dispensing package comprising opposed containers each having movable discharge means for discharging the contents-.thereo f, connector means mounting said containers in assembly, said connector means comprising first and second members motinted on the respective containers and connected for relative rotation, cooperating means on said members effective in a first position of relative rotation for preventing relative axial movement between said containers and effective in a second position of relative rotation for permitting relative axial movement between said containers and toward each other, and a discharge spout on said connector means for receiving both said container discharge means and for simultaneously dispensing and mixing the contents of said containers, whereby said contents are dischargeable from said containers through-said spout only when said cooperating means is in said second position and said first and said second members and their respective containers are moved toward each other.
