Morroffino INVENTOR.

www, ,awww/@ l ATTORNEYS United States My invention relates to devices for dispensing pastelike materials and provides a means for dispensing two or more paste-like materials of different character, for example, diierent color, in the form of a striped stream.

The device of my invention comprises an elongated hollow tube the outside dimension -of which is sized :to tit into the discharge port of a container designed for dispensing paste-like material. The hollow tube is of suiiicient length to extend from the discharge port back into the container. Between the outer surface of the hollow tube and the inner surface of the discharge port of the container are at least one and preferably a plurality of lateral passages which run approximately lengthwise of the hollow tube. These lateral passages terminate at the head end just before the outer end of the central discharge passage delined through the center of the hollow tube and discharge port of the container. Each lateral passage opens at its inner, i. e., tail, end into the dispensing container. The head end of each lateral passage communicates inwardly with the central discharge passage through a striping port adjacent to the outer end of the central discharge passage which is directed transversely to the direction of the central discharge passage.

The dispensing container is iilled with the materials to be dispensed in the form of a striped stream by rst charging into the dispensing container the material which is to form the stripes. This material is charged into the head end of the dispensing container around the hollow tube in a quantity such that it does not fill the dispens-` ing container beyond the point to which the tail end of the hollow tube extends into the container. The base material which is to form the body of the striped stream and to -carry the stripes is then charged into the dispensing container to fill the balance of the container spacet When my device is used, the pressure applied to the dispensing container to dispense a stream of material forces the base material which forms the body of the dispensed stream out through the central discharge passage inside of the hollow tube and the discharge'port. The pressure applied to the container and thereby to the base material is transmitted by the base material to the striping material which is packed within the head end of the dispensing container around the outside of the hollow tube. As a consequence of this pressure the striping material is forced through the lateral passages toward the head end of the tube and thus to the striping ports. The striping material is forced through the striping ports transversely into the stream of base material passing through the central discharge passage. In this manner, the striping material is made part of a solid lstream of both materials emerging from the discharge passage of the dispensing container in the form of a striped stream.

In a particularly advantageous embodiment of my invention, the hollow tube is provided with its own separate container for the striping material so that theoperation of lling the dispensing container is greatly simplied. In such an embodiment, the lstriping material conatent back toward the tail end of the tube andtsurrounds the tube for a portion of its length to provide space for the striping material. The striping material container *is filled with the striping material and the surface of the striping material may be covered with a protective` coatlA ing, for example, wax or' the like, toprevent -inixin`g of` the striping material and the base material. The hollow tube and associated striping material container assembly" is then positioned in the dispensing container by placingthe head end of the hollow tube in the discharge port 0fthe dispensing container.` The base'material is thenl charged to the dispensing container to iillthe balance of the dispensing container space. l By` employing 4 this embodiment of my invention, the llingoperatio'n is` greatly simplified, for the only deviationfrom accom-f ventional filling operation employing 'a single material would be the insertion of the hollow tube and -lled= strip ing material container assembly into thedispensing 'con-l tainer prior to charging the base material. 'When emi-` ployed in conjunction with conventional paste containers, i. e., disposable aluminum tube dispensing containers, the container for thel striping material` .is advantageously? formed from an aluminum blank in the samemanner, as? the conventional aluminum tube and shaped'andtsized to iit snugly within the head of the conventional alumi-S num tube. When employed with* other dispensing containers, the shape of the striping material container should conform to the internal contour of the head end-ofthe dispensing container with which it is totbe used.

ln the application of the device of my 'invention to two or more materials differing in color, the stripedtstreanA which is produced by my device presents thedispensedA materials to the consumer in a very appealingform.'

This is particularly true when my device is used todis-i pense a consumer product such as toothpaste. p Toothpaste dispensed in a striped stream, for example, awhite' base material with red striping to resemble peppermint candy, is a particularly appealing form for children. fThe` `striping material may be` simply base'material'to which color has been added, or it may be an activeingredinb in the resulting striped stream. For example, `my'device may be used to dispense a stream of white toothpasteT carrying green stripes of chlorophyll. #Mydevice alsoV be degraded by prolonged contact with each otherig4 In` such a case, my device allows the incompatible materials to be packaged together, separated by a'layer of Waxtor the like, and dispensed together by the consumer, but pre-M vents `any prolonged contact of the materialsrom ,the time of packaging to the time of actual use.

In all applications of my device, it functions. ast

metering device, mixing the materials` in the proportions dictated by the relative sizes of the inside ofthe hollow tube and the striping ports a-s well' as byvthenumber of lateral passages and associated stripingpor-t's; `The inside diameter ofthe hollow tube, thel'diameter of the* striping and. the size of the lateral passages assodegrade by Acon-tact with the paste-lilre materials to be dispensed; V'Plastics lare the most suitable materials from the' s tandpointof ease of fabrication and over all cost, but aluminum, Stainless steel, or other metals are also suitable. Tube stock of a suitable plastic, such as cellulose lacetate or polyethylene, may be used and the necessary. ports 4and .passages formed therein, or the hollow tube of my device may be molded from a suitable plastic anchas cellulose acetate or polyethylene. Where a striping material container. is used in association with the hollowtube, such striping material container may be formed of Va suitable plastic by molding or the like, or it may be formed from aluminum blanks in the same Vmanner as conventional disposable aluminum tube dispensing' containers are made, and then assembled with the hollow tube by; force tting the two pieces together. .The .structure of several embodiments of my device will be described in connection with the accompanying drawings in which:v

In the drawings, Figure l is an illustration of a hollow tube and associated striping material container assembly in which the striping material container is shaped to fit snugly within the head end'of a conventional disposable aluminum tube dispensing container. In this illustration, the hollow tube 10 is provided with grooves 11 which terminate close to the head end 10a of the hollow tube 10 in holes 12 which pass through the wall 13 of the tube 10 and so connect the grooves 11 and the inside of the tube 1t). The striping material container 14 is formed of a truncated conical portion 15 and a cylindrical portion 16. The small end of the truncated conical portion 15 is sized for a force iit over the hollow tube 10. The striping material container 14 is positioned on the hollow tube 1t) a suicient distance from the head end 10a of the tube 19 so that the head end of the hollow tube 10 can be inserted into the discharge port of a dispensing container. The striping material container 14 should be sized to fit snugly into the head end of the dispensing container with which it is to be used both to aid in holding the hollow tube 1l) in place and to prevent the base material charged to the dispensing container from leaking by the outside surface of the striping material container 14 and contaminating the striping material passing to holes 12 through grooves 11. In the illus tration in Figure l, the hollow tube 10 and associated striping material container 14 assembly is shown in a form for use with conventional disposable aluminum tube dispensing containers such as are commonly used for paste-like materials, e. g. toothpaste and the like, and therefore, the striping material container 14 is formed of the truncated conical portion 15 and the cylindrical portion 16. When used with any other type dispensing container the outside surface of the striping material container 14 should be shaped to iit the internal contour of the head end of the dispensing container and the head end 10a of the hollow tube 1u would extend a suicient distance beyond the striping material container 14 to extend into the discharge port of the particular dispensing container employed.

When the hollow tube 1u and associated striping material container 14 assembly are to be employed with a dispensing container, the striping material container 14 is first lled with striping material and a layer of wax or the likelmay be lapplied over the surface of the striping material to prevent mixing of the striping material and base material within the dispensing container. The hollow tube 10 and'associated striping material container 14 assembly is then placed within the dispensing container with the head end 10a of the tube 10 extending into the discharge p'ort of the dispensing container. Base mate- `rial is then charged to the dispensing container to fill the balance of the container space, and the dispensing container is ready to dispense a striped stream of material.

Figures 2 and 3 show the hollow tube 1t) and's-triping material container 14 assembly of Figure l in place in the head end of. a conventional screw top disposable aluminum'tube dispensing container 17.

A hollow tube 10 without the associated striping material container yis shown in place in a conventional Screw top disposable aluminum tube dispensing container 17 in Figures 4 and 5. The hollow tube 10 is positioned by a force fit in the discharge port formed by the inside surface of cylindrical wall 18 of the dispensing container 17. The outside of the cylindrical wall 18 is provided with external threads l?. In this embodiment, the striping material would be packed within the container 17 to ll the container space yaround the hollow tube 10, and the balancejof the container would 'be filled with -base material. `Such an arrangement is not as advantageous as that illustrated in Figures 1, 2 and 3 because the filling operation is' complicated by the requirement of charging two different materials to the dispensing container thus requiring two separate filling operations, and the quantity d of striping material charged to the dispensing container .ansehen cannot exceed thatV requiredA topll the dispensing' conf' tainer to the level of the tailr end b of the hollow tube yIn previous illustrations, 4the hollow tube has been shown as positioned in the ydischarge port of the dispensing container by sizing the hollow tube so as to provide for a force tit of thehollow tube into the discharge port. An alternative means of positioning `the hollow tube in the discharge port of the dispensing container is illustrated in Figure 6. In this illustration, the hollow tube 10 is provided with a cap 20 which is rigidly fastened to the head end 4of the hollow tube 10. The cap is sized so that the cylindical side which extends back over the tube 10 from the head end 10a has an inside diameter greater than the outside diameter of the tube 10 by an `amount sufficient to accommodate between the outside surface of the tube lttand the inside surface of the cylindrical side of the capr20 the wall forming the discharge port of a dispensing container, for example, the cylindrical wall 18 of the dispensing container 17 illustrated in Figure 4. The cylindrical side of cap 20 is formed with internal threads 21 and external threads 22. In this form the hollow tube 10 is inserted into the discharge port of a dispensing container provided with` of the discharge port of the dispensing container fas a.

closure.

`A slightly modified hollow tube 10 is illustrated in.

Figure ln this illustration, Ithe tail end of the hollow tube lit `which when in place in the discharge port of anassociated dispensing container extends into the dispensing container is flared outwardly as shown vat 23 to ease the flow of base material entering the hollow tube from the dispensing container as pressure is applied to the container to dispense a stream of material. In the hollow tube 1t) illustrated in Figure 7 the grooves 11 Vas shown do not extend all the way to the tail -end of the hollow tube itl. It is not necessary in any of the hollow tubes illustrated in the drawings that the grooves 11 extend to the tail end of the hollow tube. The only requirement is that these grooves connect' the body of paste-like striping material and the holes 12 through the wall of the tube 19 so as to 'allow striping material to enter and join the stream of base material passing through the hollow tube. However, the hollow tubes are usually more easily fabricated with the grooves extending to the tail end of the tube 10 and this added length of these grooves is some aid in easing the ow of striping material to the holes 12.

A modified hollow tube 10 yand associated striping material container 14 assembly such as shown in Figure 1 is illustrated in Figure 8 with the cylindrical portion 16 of the striping material container 14 of Figure 1 cut away to show more clearly the added partitions 24 and 25 which divide the striping material container 14 into two separate compartments. This form allows twodiferent `striping materials to be employed to produce a striped stream made up of a 'base material and two dilerent striping materials. As illustrated in Figure 8, two grooves 1 1 are positioned in each of the separate stripingmaterial containers. The partitions 24 and 25 separating the striping material container 14 into two compartments` vwhile the above descrpun is dirctdffef-themes-t part to dispensing containers of the conventional disposable aluminum tube type, it will be readily apparent that other types of dispensing containers for paste-like materials can be modified to dispense two or more materails in the form of a striped stream by employing a hollow tube or a hollow tube and associated striping material container assembly having the general characteristics described above and adapted to be used with a particular dispensing container. For example, cake decorators of the plunger type can be so modied very readily.

Referring to Figures 9 and 10, a cake decorator 30 having an elongated cylindrical body 31 is shown. The tail end of body 31 is crimped to form threads 32 which engage a threaded cap 33. Cap 33 is provided with a central aperture 34 through which an elongated rod 35 freely extends.

and centrally supports a transversely positioned piston 37 which is aixed to rod 35 by a pair of nuts 38 which are threaded upon rod 35, one onV each side of pistonform threads 39 which engage a similarly threaded por,

tion of a conical cap 40. The apex of cap 40 is provided with a cylindrical extension 41 which forms a discharge port for the contents of decorator 30. The

head end of extension 41 is provided with an internal.

annular flange 42 and is externally threaded at 43 to engage a shaping cap 44. Shaping cap 44 has a central bore 45 registering at its inner yend with the central open portion of lange 42 and tapering at its outer end to an orifice 46 of any desired shape to control the transverse dimensions of the extruded stream of decorating paste.

Internally extension 41 is slightly tapered to permit internal sliding reception of plug 47, the details of which are seen more clearly in the enlarged perspective view in Figure 1l. Plug 47 is formed as an integral, molded piece and includes a hollow tubular portion48 which extends the entire length of plug 47. Pour bosses 49 spaced to define longitudinal slots 50 extend outwardly from and lengthwise along one half of hollow tube 48 at equal arcuate intervals about such half. Tube 48 is grooved slightly at S1, the bottom of each slot 5G, and is provided with a radial end slot 52 at the head end of each such groove S1. Plug 47 is internally received in extension 41 with its end having slots 52 seated on ange" 42. The outer surface of each boss 49 abuts the inner surface of extension 41 and the tail end of hollowltube 48 extends beyond bosses 49 and extension 41 back into body 31.

Cake decorator 30 is employed similarly to the devices previously described. Cap 40 is removed from body 31. Plug 47 is then inserted into extension 41 of cap 40 and striping paste is packed into the space between cap 40 and hollow tube 48. Base material is then packed into `the open end of body 31 and cap 40 is rethreaded over the open end of body 31. A suitable shaping cap 44 is positionedon the head end of the decorator and handle 36 is pushed in to force a main stream of base material through the passage including the open centers of hollow tube 48, ange 42, bore 45 and orifice 46.

At the same time striping material is forced through the passage between slot 50 and the inner wall of extension 41 toward the space between slot 52 and flange 42 through which the lstriping material transversely env Vters the stream of base material as it emerges from hollow tube 48 and passes through ange 42.

A modilication of plug 47 to provide an associated striping material container is shown in Figure l2. In this arrangement a conical skirt 53 is aixed about plug 47 `over the half which is free of bosses, 49. The narrowV end ofskirt 53 is attached to the tail end of" bosses 49,

At its external end, rod 35 is benttoy form a handle 36. The inner end of rod 35 is threaded,

arsaffsi spaced outwardly from. tube 48 so that slots 50 open into the space between skirt S3 and the tail endr of tube 48. Thewide end of skirt 53 carries a short cylindrical portion S4 to conform the outside shape of the container to the conventional shape of collapsible tubes.

The arrangement of Figure 12 is used similarly to that of- Figure l, but is speciiically employed where the discharge port of a collapsible tube or plunger tube has an internal iiange rather than a straight-through bore.

Figures l3 and 14 illustrate the dispensing end of an otherwise conventional collapsible dispensing tube 6i? such as can be used for dispensing toothpaste and the like. The bodyV 61 of dispenser 60 is tapered at its dispensing end to a discharge port 62 formed as a hollow cylindrical projection from the tapered end of body 61. Externally discharge port 62 is provided with threads 63 for receiving and engaging a conventional closure cap (not shown). At its open outer end, discharge port 62 is turned inwardly to form anannular flange 65, the inner surface of, which functions as a seat for a plug 67.

The inner surface of the cylindrical portion of discharge port 62 is tapered slightly inward toward flange 65. and is provided with four grooves 64 running lengthwise of port 62 which at their inner, i. e., tail, ends open into body 61 and which at their outer, i. e., head, ends communicate with four corresponding radial grooves 66 in the inner surface of flange 65. The latter, radial, grooves open into the central aperture defined by annular ange 65.

Plug 67 is formed as an integral molded piece and includes a hollow tubular portion 68 which extends the entirev length of plug 67 and which carries at one end an enlarged head 69 shaped with a slight inward taper toward its outer, head, end such that plug 67 is tightly received at itshead end within discharge port 62. When so positioned, the yend face of head 69 abuts the inner faceV of ange 65 and the lateral surface of head 69 abuts the inner surface of the cylindrical portion of port 62. Tube 68 thus projects back from head 69 into body 61 of dispenser 60 to define a space for receiving striping material.

p In use the dispenser shown in Figures 13 and 14 is filled in substantially the same manner as the dispenser shown in Figures 4y and 5, for example. striped stream of material occurs when body 61 is squeezed since theV grooves 64 and 66 form passages leading from the supply of striping material betweenV the inner wall of. port 62 and outer surface head 69 of plug 67 and discharging into the main stream through the center of tube 68 in a transverse direction to the direction of iiow throughy tube 68.
