Description

L. H. BLOOM STRIPING DISPENSER Filed April 19, 1957 Nov. 8, 1960 INVENTOR. fr H. BzaoM United States Patent() "vice srRrPiNG DISPENSER Lee H. Bloom, Larchmont, N. assignor to Lever Brothers Company, New York, N.Y., a corporation of Maine Filed Apr. 19, 1957, Ser. No. 653,821

2 Claims. (Cl. 222-94) The invention relates to an improvement in devices for dispensing fluent or paste-like materials of different character and particularly to improvements in dispensing two or more paste-like materials of different color.

In one aspect of the invention, it is particularly applicable to coaxial collapsible dispensing tubes for producing a striped tooth paste product. The coaxial collapsible dispensing tubes heretofore known have been concerned with maintaining two chemically reactive ingredients in separation until they are dispensed. When such devices are attempted to be used to produce a striped tooth paste product, it has been found that they are virtually inoperative to produce such a product which is commercially acceptable.

One of the principal disadvantages in the use of the dual coaxial tube arrangement for producing a striped tooth paste product is that the space between the inner tube and the outer tube, which space contains the striping material, must be so small to contain the small amount of striping material needed to form only a thin surface stripe without spreading over the remaining surface of the paste stream that considerable ditliculty is experienced in filling this space. The problem, therefore, is to provide a structure for utilizing the total amount of striping paste which is contained in this space commensurate with ease in filling.

In another aspect of the invention, it is applicable to the single tube type dispenser. In this arrangement the invention operates in the same manneras it does with the coaxial tube dispenser. Sufficient paste material to furnish the striping is provided by extending the main discharge passage into the interior of the tube a short distance, surrounding it with striping paste material, and providing additional discharge passages or ports therefor. This arrangement likewise would utilize only a very small and critical amount of striping paste if only a thin surface stripe is to be provided.

Accordingly, it is a principal object of the present invention to provide a structure for producing a striped tooth paste product which permits the striping material to extend substantially to the center of the stream of tooth paste.

Another object of the invention is to provide a construction for dispensing striped `tooth paste. Y Y

A further object of the invention is to providea striped tooth paste product utilizing paste material of two different characteristics without having one paste material be exhausted before the other.

It is also an object of the invention to provide a construction for utilizing paste material of two different characteristics to produce a unitary stream.

Generally, the invention includes a plurality of circumferentially disposed pie-shaped or substantially triangular outlet passageways at the inner end of the discharge passageway of a collapsible tube dispensing container. Paste material from a body of one characteristic will be extruded through each of these pie-shaped pas` sageways into the discharge passage to provide a portion The various novel features of construction, combina-4 tion and relation of parts by which the foregoing and other objects are attained are set forth in detail in the following specification.

The drawing accompanying and'forming part of the, specification illustrates one practical commercial embodi ment of the invention as applied to a paste dispensing- It should be understood, however, that the inven tion is not limited to this use or to this particular for-m tube.

of structure or dispenser as will appear from the scope of the appended claims.

. In the drawing:

Figure 1 is a View partially in section showing the construction of the invention for a single tube type of,

dispenser;

Figure 2 is an end view of the construction shown in Figure 1;

Figure 3 is a view partially in section showing the construction of the invention for a dual tube type of dispenser; and

Figure 4 is a perspective view of the insert used withk one form of the single tube type of dispenser and provided with pie-shaped outlet passageways according to one embodiment ofy the invention.

For the purposes of this description, it will be assumed that the dispensing device is to be used to dispense toothpaste which presents the appearance of being striped, it being understood that the invention is not limited totooth paste or to the specific characteristics of the structure described. i I

Referring first to the single tube type dispenser, Figure 1 of the drawings shows a conventional disposable aluminum tube dispensing container 10 with a sloping forward end 11 terminating in a head end 12. The outer surface of the head end 12 is provided with a plurality of threads 13 for securing a cap (not shown). The discharge passageway 14 of the tube 10 extends from a discharge port 15 at the outer end to a plurality of pie-shaped outlet passageways 16 at the inner end. The outlet passageways 16 may be formed in one. end of an insert 17 as shown in Figure 4, or they may be formed integrally with the discharge passageway 14 and, therefore, separate from the insert 17.

The spaces intermediate of the outlet passageways 16. are communicated by means of a plurality of passageways 18 with a zone defined between the sloping forward end 11 and the hollow insert 17. This is illustrated more clearly in Figure 4 which diagrammatically indicates that the passageways 1S communicate with the discharge passageway 14 at the points 19, 20 and Z1 intermediate each of the outlet passageways 16 in the hollow insert 17.

( The dispensing container 10` is first iilled withy the ma-I terials to be dispensed in the form of a striped streamy by first charging into the dispensing container the material which is to give the appearance of the stripes (i.e., a red tooth paste, for example). This material is charged into the head end of the dispensing container 10 about the hollow insert 17 in such a quantity that it does not fill the container beyond the point to which the inner end of the insert 17 extends into the container. The material which is to form what will appear to be the body of the striped tooth paste (i.e., white tooth paste, for example) is then charged into the dispensing container 10 to lill the balance of the container space.

In operation, the pressure applied to the dispensing Patented Nov. 8, 1960 container in the usual manner forces the white tooth paste through the center of-the hollow insert 17 and through each of the pie-shaped outlet passageways 16. The pressure applied to the container is transmitted by the white tooth paste longitudinally in a forward direction to the red t-ooth paste which is packed in the head end' of the dispensing container 10 about the hollow insert 17. As a result of this pressure, the red tooth paste is forced through the passageways 18 to ll the space between each of the streams provided by the outlet passageways 16 thereby forming in the discharge passageway 14 a completed stream of striped `tooth paste. Since the striping material (red tooth paste) forms a substantial part of the unitary striped tooth paste product, the length of the hollow tubular member 17 may extend back into the container 10 past the sloping forward end 11 thereby providing ample space to contain sufficient striping paste for -the total amount of tooth paste contained in the balance of the container 10.

The invention has particular applicability with the dual coaxial type of tube construction. With-this type of construction, ample space may be formed -between the inner tube and the outer tube to permit ease in lling since a substantial amount of the striping paste is used with a construction according to the present invention. As shown particularly in Figure 3 of the drawing, the numeral 30 represents an inner collapsible container of any suitable material such as a conventional disposable aluminum tube dispensing container. Formed coaxially about the inner tube 30 is an outer tube 31 which is formed of the same material. The sloping forward end 32 of the outertube 31 terminates in a head end 33 which is provided with a plurality of threads 34 for securing a cap v(not shown). The inner-surface of the head end 33 is provided with -a plurality of threads 35 into which is threaded the head end 36 of the inner tube 30. Of course the head ends 33 and 36 of the coaxial tubes 31 and 30, respectively, may be attached or positioned by any other suitable means, if desired.

A discharge passageway 37 extends from a discharge port 38 at the forward end of the head end 36 back to a plurality of pie-shaped outlet passageways 39 which are similar to the outlet passageways 16 as shown in Figure 2 of the drawing. A plurality of passageways 40` communicate the spaces intermediate of the outlet passageways 39 with the space between the inner tube 30 and the outer tube 31.

In operation, the tooth paste which is to form onepart of the striped stream is lled into the inner tube 30, as for example, white tooth paste. Tooth paste of another color, as for example, red, is lled within the space between the inner tube 30 and the outer tube 31. By ap# plying pressure to the dispenser in the customary man ner, a plurality of pie-shaped streams of white tooth paste are formed by the outlet passageways 39 and the space between each of these streams is filled by red tooth paste from the passageways 40. Thus, as the stream is extruded out the discharge passageway 37, the resulting product will have the appearance of a striped tooth paste product.

While the invention has been described with reference to the particular construction shown, it is not restricted to the exact details herein disclosed and this application is intended to cover such modications or changes as may come within the purposes of the invention or the scope of the following claims.

I claim:
