Co., Rockford, 111., a corporation of Illinois Filed Mar. 22, 1965, Ser. No. 441,707 18 Claims. (Cl. 141105) ABSTRACT OF THE DISCLOSURE Apparatus for dispensing a striped stream of comestible into containers and having a stationary nozzle with a discharge opening. A composite stream of ice cream and syrup is discharged from the stationary nozzle, and a rotary nozzle adjacent the discharge opening dispenses a plurality of oblique stripes of syrup on the surface of the composite stream.

This invention relates generally to a material dispensing apparatus and more particularly to a nozzle apparatus for dispensing multiple materials such as an ice cream and a syrup.

With the advent of the use of semi-transparent plastics for packaging, the consumer has been able to observe the contents and make his selection based on color and the like. Thus, when dispensing a material comprising a combination such as ice cream and syrup, it is desirable to have a quantity of the syrup adjacent the side of the package to be seen by the consumer.

An important object of this invention, therefore, is to provide an improved nozzle apparatus for dispensing a stream comprising a multiple of materials, in which the periphery of the stream shows visual evidence of said multiple materials.

Another object of this invention is to provide an improved nozzle apparatus for dispensing a plastic comestible and a syrup in which both are dispensed through a single discharge opening.

Still another object of this invention is to provide an improved nozzle apparatus for dispensing a stream of plastic comestible and syrup and for applying an oblique strip of syrup to said stream of material.

A more particular object of this invention is to provide an improved nozzle apparatus for dispensing a plastic comestible and a syrup and including a rotary nozzle which is mounted for rotation about the periphery of said stream of material and has a plurality of ports for applying a plurality of oblique stripes on the stream of material as the rotary nozzle is rotated.

Yet another object of this invention is to provide an improved nozzle apparatus in accordance with the above objects and which includes a rotary nozzle which may be readily removed for cleaning and maintenance.

These, together with various ancillary objects and advantages of this invention will be more readily appreciated as the same becomes better understood by reference to the following detailed description when taken in connection with the accompanying drawings wherein:

FIG. 11 is a side view of a container filled by the material dispensing apparatus of FIG. 5 with the container shown in section to illustrate a typical pattern of the ma terial dispensed.

In general, the nozzle apparatus in accordance with the present invention, contemplates a first nozzle for dispensing or emitting a first material and a second nozzle for dispensing or emitting a second material on the periphery of the first material. The first material may be of any kind which can be dispensed through the nozzle and may be a plurality of materials, such as a mixture of plastic comestibles. In its preferred form, the nozzle apparatus is utilized to dispense a first material comprising a mixture of ice cream and syrup; however, this has been done by way of example and it is contemplated that other types of materials may be used in conjunction with the present invention. The second material is preferably a liquid or semi liquid, for example a syrup, and it is contemplated that the second material be discharged or emitted by the second nozzle onto the surface of the first material. It is also contemplated that the second nozzle have a port or orifice which is substantially smaller than the periphery of the material passing through the first nozzle whereby the second material is dispensed in a stripe on the first material. Means is provided to move the first and second nozzles relative to each other whereby the stripe of second material is dispensed in a generally oblique pattern. As used herein, the term syrup comprises liquids or semiliquids at normal room temperature which may include solid materials such as nuts, fruits, candies and the like.

Reference is now made more specifically to the accompanying drawings wherein one embodiment is illustrated in FIGS. 1-4. FIG. 1 illustrates a nozzle apparatus, generally designated by the figure 15, mounted on a container filling machine 16. One suitable filling machine is disclosed in detail in Patent No. 2,765,601 issued to Ralph F. Andreson. In general, the filling machine disclosed in the aforementioned patent includes an ice cream dispensing apparatus 17 which is adapted to measure a predetermined quantity of the material supplied thereto and to dispense the same into containers 18 which are presented thereto by a conveyor 19. The filling machine also includes a syrup dispenser 20 which has been modified to dispense a predetermined amount of syrup simultaneously with the ice cream dispenser 17 and feed the same into the nozzle apparatus 15 by means of conduit 21, shown in dashed lines in FIG. 1. The dispensing mechanism 17 includes a measuring chamber 22 and a valve assembly 24. As described in the aforementioned patent, the valve assembly 24 comprises a valve body 26, a cylindrical discharge element 28, and a cylindrical by-pass valve element 29, as best illustrated in FIG. 2, which operates to control the flow of material for measuring and for discharge.

Valve element 28 is provided with a segmented slot 34 which, in a fill position (not shown) passes material from inlet connection 36 through the inlet passage 38, segmental slot 34 and passage 39 to the measuring chamber 22. In such a fill position, wherein the segmental slot 34 is in a substantially horizontal position, the segmental slot also communicates with a passage 48 that communicates with the by-pass valve element 29. Valve element 28 is rotatable through substantially 90 to a dispense position such as shown in FIG. 2, wherein the valve element closes the inlet passage 38 and connects the measuring chamber 22 with a discharge passage 42 to dispense material from the measuring chamber. Material is intermittently dispensed from the measuring chamber 22 in response to actuation of a switch 43 by extension of piston rod 44 attached to a piston in the measuring chamber when the latter is filled. The switch operates a drive mechanism (not shown) which reciprocates the arm 44 and slide 41 to drive the piston in the measuring chamber downward in a dispensing stroke, and which drive mechanism also moves the valve 28 to the dispense position. A container detector in the form of an engaging finger 30 detects the presence of a container 18 at the filling station and controls operation of the valves 28 and 29 to bypass the material from the measuring chamber 22 in the absence of a container. The container detector also controls a syrup valve (not shown) to open the same only if a container is in filling position at the nozzle. More exact descriptions of all the above elements and their functions are given in the aforementioned patent to Ralph F. Anderson and further description herein is deemed unnecessary.

The nozzle apparatus is disposed beneath the discharge passage 42 and may be attached to the valve body by any convenient means which will allOW convenient removal of the nozzle apparatus for cleaning and maintenance and, as herein shown, this attachment is accompanied by means of fasteners such as bolts 45 and 45 which extend through holes 46 and 46' respectively (FIG. 3). Nozzle apparatus 15 includes a first nozzle means and a second nozzle means. In the embodiment illustrated, the first nozzle means is a stationary nozzle 50 and second nozzle means is a rotary nozzle 51. As best seen in FIG. 2, stationary nozzle 50 includes a lower member and an upper member 56. These two members have a throat 52 which is substantially coaxial with discharge passage 42 and terminates in a substantially circular downwardly facing discharge opening 53. A material feed means shown in the form of a duct 58 extends into the general area of throat 52 and has a downwardly facing orifice 59 substantially centered on throat 52. Duct 58 is communicated with syrup conduit 21 by means of passage 60 in valve body 26. In this manner, a second material, such as syrup, may be fed into the center of the throat 52 as illustrated in the dashed lines in FIG. 2. When a first material, such as ice cream, is dispensed through discharge passage 42 and throat 52, and syrup is fed through orifice 59 and duct 58, a stream of material dispensed from discharge opening 53 will be a combination of the aforementioned materials.

Interposed between the upper and lower members of stationary nozzle 50, is rotary nozzle 51 having a generally smooth inner wall 64 substantially concentric with throat 52. Thus, rotary nozzle 51 includes an annular member extending around the stream of material dispensed. O-rings 73 and 74 are interposed between the rotary nozzle and upper member 56 and lower member 55 respectively to provide a seal and thereby retain the stream of material in the throat 52. A plurality of ports 65 are arranged in the inner wall 64 and ducts such as 66 connect the ports with a generally circular channel 67 in lower member 55. Syrup is retained in the channel by the aforementioned O-ring 74 and O-ring 75 between the rotary nozzle and the lower member. Channel 67 is connected to syrup conduit 21 by means of passages 60, 68

and 69. Passage 68, which extends through lower member 55 and valve body 26, conveniently has an O-ring 76 to provide a seal at the junction of the two parts. Syrup may thus be fed to ports 65 and dispensed therethrough. The ports have a size substantially smaller than the size of the stream of material thereby dispensing the syrup in a stripe on the surface of the stream of material. Means is provided for feeding the syrup to the ports and for dispensing the same therethrough and, as illustrated, this function is performed by syrup dispenser 20. It is contemplated that means he provided for moving the rotary nozzle 51 thereby moving the ports 64 along the periphery of the stream in a direction crosswise of the direction of fiow to deposit the stripes in an oblique pattern on the surface thereof. In this manner, the stripe will be prominent in generally transparent container 18 as shown by stripe S in FIG. 2. In the embodiment illustrated, gear means, such as worm gear 70 on drive shaft 72 is provided for this purpose. Accordingly, rotary member 51 has a geared outer edge 71 to be driven by worm gear 70. A motor (not shown) is operatively connected to the shaft 72 to drive the rotary nozzle member. Since material dispensing apparatus 16 is an intermittent discharge type machine, it is contemplated that the syrup dispensed through ports 64 and orifice 59 also be intermittently discharged substantially simultaneously with the discharge of material through discharge passage 42 as disclosed in the aforementioned patent. However, it is contemplated that an additional quantity of syrup could be dispensed on top of the material contained in container 18 to conveniently provide a topping, if desired.

Another embodiment, one suitable for a continuous dispensing of material, is illustrated in FIGS. 5-11. FIG. 5 illustrates a nozzle apparatus, generally designated by the figure 80 rigidly mounted on a material dispensing apparatus 81 as by an arm 82 and a column 83. One suitable dispensing apparatus is disclosed in more detail in Patent No. 3,124,916 issued to Ralph F. Anderson and Robert P. Sorensen. In general, the material dispensing apparatus disclosed in the aforementioned patent includes a conduit 84 for feeding a plastic material to a nozzle apparatus. The containers 18 are elevated into telescoping relationship with the nozzle apparatus 80 by a container elevating apparatus 86 and are supported by a support apparatus 87 during filling of the containers 18. The containers are conveniently advanced onto the elevating apparatus 86 by means of an inlet conveyor 88 and removed from the area beneath the nozzle apparatus after filling by means of a container engaging arm 89 which moves the containers 18 onto a second conveyor 90. More exact descriptions of the above listed elements and their functions are given in the aforementinoed patent to Ralph F. Anderson and Robert P. Sorensen and further description herein is deemed unnecessary. It should be understood, however, that said filling machine is indicated by way of example and the present invention may be utilized on other such machines without departing from the spirit of this invention.

The aforementioned patent contemplates that the container 18 be elevated into telescoping relationship with the nozzle apparatus and then moved downward under the weight of the material dispensed and the pressure on the stream from the nozzle apparatus. When the container 18 is filled, the mouth of the container is disposed adjacent the lower end of the nozzle and the container is then moved crosswise of the nozzle to shear the material in the container from the stream of material in the nozzle apparatus. In this manner, a continuous stream of material from the nozzle apparatus can be utilized since a second container will have been moved into position on a container elevating platform of the container elevating apparatus 86.

Nozzle apparatus 80 comprises a first nozzle means and a second nozzle means. In the embodiment illustrated, the first nozzle means is a stationary nozzle 91 and second nozzle means is a rotary nozzle 92. As best seen in FIG. 6, stationary nozzle 91 includes a generally upright stationary inner member 93 defining a throat having a downwardly facing circular discharge opening 94 which has a cross section somewhat smaller than the cross section of the container to be filled. A generally upright stationary outer member 95 substantially encircles inner member 93 but is spaced therefrom for purposes which will hereinafter become apparent. Outer member 95 has an outer size generally approximating the inside diameter of the container for generally engaging the same in telescoping relationship as described supra. Outer member 95 has a generally smooth lower edge 96 disposed at a level somewhat below the discharge opening 94 to provide a substantially smooth stationary shear edge to shear the material in the container from the stream of mate rial being dispensed from the nozzle apparatus.

Interposed between inner member 93 and outer member 95 is rotary nozzle 92 which includes an annular member 125 extending around the stream of material dispensed. A plurality of ports 126 are arranged in the annular member for discharging a quantity of a second material onto the periphery of the stream of material. Each port includes a protuberance 127 extending in an inwardly direction toward the flow of material being dispensed. Ducts such as 123 communicate with the ports 126 and with a generally circular channel 130 in the annular member. Channel 130 is connected to conduit 132 to receive a quantity of the second material, such as syrup, therethrough. In this manner, syrup is fed to ports 126 and dispensed therethrough. The ports have a size substantially smaller than the size of the stream of material and thereby dispense the syrup in a stripe on the surface of the stream of material. It is contemplated that means be provided for moving the rotary nozzle 92 thereby moving the ports 126 crosswise of the stream of material and depositing the stripes in an oblique pattern on the surface thereof. In this manner, the stripe will be prominent in container 18 as shown at S in FIG. 11.

In the embodiment illustrated, the means for moving is in the form of motor 140 which drives rotary member 92 through belt 139, pulley 138, shaft 136, and gear 134 which communicates with geared outer edge 133 of the rotary member.

Rotary member 92, inner member 93 and outer member 95 are mounted adjacent the lower end of an expansion chamber which receives a first material such as ice cream, through duct 84 as hereinbefo-re described. The expansion chamber has a cross sectional area which is large as compared to the flow area of duct 84 and functions to accumulate the material and reduce the velocity at which the material emerges from the nozzle. In the embodiment illustrated, the expansion chamber includes upper member 120 and lower member 122 which are fastened together as by bolts 123 extending into holes 123'. Rotary member 92, inner mmebr 93 and outer member 95 are detachably mounted on the lower end of lower member 122 as by bolts 118 extending into holes 119 (FIG. 7). O-rings 131 and 131 are interposed between rotary member 92 and lower member 122 and located on either side of channel 130 to provide a seal therefor. It is deemed obvious that these parts may be readily removed for cleaning and maintenance. In its preferred form for use with semi-fiiud or plastic comestibles, lower member 122 is inwardly inclined at the lower portion thereof and communicates with the throat defined by inner member 93, as best seen in FIG. 6. In this manner, a restriction is provided which serves to retain the material in a continuous stream as when one container 18 is being removed and a second one being brought into position from underneath. Thus, the particular shape serves to keep a portion of the flow of material from breaking off during this period of the operation It should be noted that this is particularly advantageous when the nozzle apparatus is being utilized in an operation requir- 6 ing continuous flow of material. It should be understood, however, that the apparatus shown is not limited to this type operation.

In the embodiment illustrated, conduit 84 feeds the first material into the inlet of a T-shaped fitting 99. Fitting 99 is conveniently detachably connected to upper member 120 of the expansion chamber by a coupling 121, as best seen in FIG. 6. A second material is advantageously introduced into the first material and for this purpose, a conduit 102 is mounted on the fitting 99 and extends generally into the center of the chamber formed by the T- shaped fitting. Conduit 102 has an inlet 100 attached to a conduit 103 (FIG. 5) to receive the second material. Adjacent the lower end of conduit 102 are a plurality of orifices 105-112, as best seen in FIGS. '8 and 10, which open at points spaced inwardly from the walls of the chamber in the T-shaped fitting. In this manner, the second material, such as a syrup, may be injected into the body of the first material which is being fed through conduit 100. Adjacent the lower end of the conduit 102 is a paddle 113 affixed thereto by a bayonet-type coupling comprising a pin 114 on paddle shank 116 and an inverted J-slot 115 on conduit 102. Adjacent the upper end of the shank 116 is provision for an O-ring 117 to provide a closure for the end of conduit 102 and thus force the second material through the orifices previously described. Referring now to FIG. 9, it can be seen that the body of the paddle 113 is twisted or inclined through 90", or generally auger shaped, for the purpose of turning the flow of composite material, as ice cream and syrup, to provide a swirl of the syrup in the ice cream as shown at T in FIG. 11. In addition, the orifices 105-112 are conveniently arranged to direct the stream of syrup somewhat tangentially of the flow in the T-fitting 99 to enhance the swirling of the syrup in the ice cream.

It is now deemed obvious that the first nozzle means may be utilized for discharging a flow of material which may be a composite of several materials, that the second nozzle means may be utilized for dispensing a stripe of a second material onto the stream of the material being dispensed, and that the first and second. nozzle means may be moved relative to each other to deposit the stripe in a generally oblique pattern.

The hereinbefore described rotary nozzle 51 (FIG. 2) of one embodiment, and rotary nozzle 92 (FIG. 6) of the other embodiment are preferably constructed of plastic material. The use of plastic has obvious advantages in manufacturing such as in shaping and joining parts together. Additionally, when the nozzle apparatus is used with a material which requires refrigeration, such as ice cream, the insulation quality of plastic protects the second material, such as syrup, from being chilled as it flows through the duct work in the rotary nozzle and thereby prevents coagulation of the syrup in the duct work.

While I have thus illustrated two preferred embodiments of my invention, this has been done by way of illustration to indicate the scope thereof and should not be construed as a limitation thereon. I do not wish to be limited except as required by the appended claims.
