4 Claims. (Cl. 222-94) This invention relates to improvement in devices for dispensingfluent materials of different character and particularly to improvement indispensing devices whereby greater simplicity and economy in manufacture are realized.

-Generally, the invention contemplates a construction whereby greater ease in fabrication permits a substantial saving in manufacturing costs. By providing an arrangement ,of the various parts in accordance with, for example, the embodiment to be described presently, the head end or nozzle of the dispensing device may be made in one piece as, for example, by stamping or molding. The single unit nozzle is then pressed orotherwise attached to the bodyof the dispenser.

Accordingly, it is a principal object ofthis invention to 7 provide a dispensing device to contain two fluent or pastelike materials which device is easier and less costly to produce.

Another important object, of the invention is to provide a dispenser for producing astripedproduct wherein the head end of the dispenser is constructed to permit fabricaseparate nozzle construction which may be attached to a collapsible tube type of dispenser for creating two zones to contain materials of two different characteristics.

The invention provides a new and improved nozzle construction for a collapsible tube dispenser wherein the greater portion of the nozzle is hollow and a hollow tubular member extends from a main discharge port back into the container for a predetermined distance. At leastone and preferably a plurality of small apertures are disposed about the main discharge port such that fluent material contained within the nozzle about the hollow tubular member will be extruded onto the main stream emerging from the maindischarge port. A preferred embodiment of such a construction will be described in greater detail hereinafter for illustrative purposes only.

With these and other objects in view, the nature of which will become more apparent, the invention will be more fully understood by reference to the drawing, the accompanying detailed description, and the appended claims.

In the drawing:

Figure 1 shows a single-tube type of dispenser partly in section taken along the line 11 in Figure 2;

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

Figure 3 shows the nozzle construction partly in section for one form of the invention; and

.Figure 4 is a sectional view taken along the line 4-4 in Figure 3.

For simplicity in describing the invention, it is assumed that the dispensing device is to be used to dispense tooth paste in a striped form,'it being understood that the invention is not limited to tooth paste but has other applications in the art.

Referring now to Figures 1 and 2 of the drawing, the numeral 10 refers to a conventional collapsible tube dis]- pensing container which is provided with a sloping forward end 11 terminating in a head end or nozzle 12. A plurality of threads 13 are formed about the outer end of the nozzle 12 for securing a cap (not shown). Form'ed integrallywith an end surface 14 and extending back into the container 10 is an extension 16 .which defines a discharge passageway 17 therethrough. The end surface 14 of the nozzle 12 has a centrally disposed main discharge port 15 for communicating the discharge passageway 17 externally of the container 10. Disposed about the main discharge port 15 in the end surface 14 is a plurality of striping ports18 each of which is shovtm in the drawing as being formed with a slight slope for directing each striping stream against the main stream. It is to be understood, however, that the invention is in no way limited to a construction wherein thestriping ports are formed with a slope. Striping ports which have their axis substantially parallel to the axis of the main discharge port are equally .applicableto the invention. V V

Although the end surface 14 and the extension'16 are shown in Figure 1 as being formed separately from the nozzle 12, it is to be understood that these elements may be formed integrally with each other as for example by form of construction is shown in Figure 1 ofthe drawing.

With a construction in accordance with the invention,

the chamber 19 which is formed within the head end or 1 nozzle 12 about the extension 16 may be separated from the chamber 20 by a partition or diaphragm 21, if desired. The diaphragm 21 may be formed of any suitable material as for example rubber or plastic. It is desirable that the diaphragm 21, if used, must be extremely pliable so as to present negligible resistance to the transmission of pressure from the tooth paste in the chamber 20 to the striping material in the chamber 19. However, it is essential to note that such a partition is only used where desired and, as such, forms no part of the present invention.

One specific construction of the head end or nozzle 12 is shown in Figures 3 and 4 of the drawing. In this view the elements including the nozzle 12, the front surface 14 and the extension 16 are all formed integrally. In addition, a shoulder 22 extends circumferentially about the inner end of the nozzle 12 and is provided along the outer periphery thereof with a plurality of knurls 23 which form a good gripping surface for a connection with the sloping end 11 of the tubular container 10. The inner surface of the shoulder 22 is chamfered as shown at 24 to form a smooth transition from the sloping end 11 such that the chamber 19 is uniformly extended from the container 10 to the head end or nozzle 12.

Assembly of this form of construction is relatively simplified in view of the fact that the nozzle 12 and the extension 16 are molded integrally with each other. The sloping end 11 of the tube 10 is initially terminated inan open end 26, the end 25 being initially straight. The nozzle unit 12 is inserted within space 26 against a shoulder 27 and the end 25 is then pressed over the shoulder 22 to grip the nozzle 12 firmly.

The tube is filled first with the material which is to form the stripes but not past the inner end of the extension 16. The diaphragm 21, if used, is then placed about the extension 16 over the striping material in the chamber 19. Nowthe balance of the. container 10 forming the chamber is filled with the tooth paste which is, to be the main Stream and the container 10 is sealed in the usual manner.

-In operation, pressure is applied to the container 10 in the customary manner. This pressure is transmitted longitudinally in a forward direction to extrude the tooth paste in the chamber 20 through the discharge passageway 17 and out the port 15. The pressure applied to the container 10 is transmitted through the tooth paste in chamber 20 to the striping material in the chamber 19 which extrudes the striping material through the striping ports 18 onto the stream of tooth paste emerging from'the dischargeport 15.

It isto be understood that the above-described arrangements aresimply illustrative of the application of the principlesof the invention. Numerous other arrangementsnrnay be devised readily by those skilled in the art which willembody the principles of the invention and fall within the spirit and scope of the appended claims.
