Abstract
Abstract An extruder head for differently coloured streams of an ice cream product feeds these streams through a series of interlaced tubes and subtubes to a mould over which a carton is placed to receive a block of the product. The mould is divided into a series of compartments that depict a desired pattern of different colours for the block.
Description
~ ~ ~V ~7 ~
Extruder head for making a patterned block of an ice cream _________._________________________________________________ product _ ___ _ _ _ Field of the Invention ______________________ The invention relates to an extruder head for extruding streams of an ice cream product of at least two (preferably three) colours into a carton to form a patterned block of the product in such carton. The resulting block will have a substantially uniform cross-section throughout its length, such cross-section defining a pattern of different colours. As a result, this same pattern will appear wherever the block is later subject to a transverse cut.
Prior Art It is known to package ice cream by extrusion into a carton to form a block. Moreover, it is known to use more than one colour, for example to form a block in the so-called Neopolitan style, in which three colours of ice cream are layered in a single block.
Summary of the Invention ________________________ The present invention enables the formation of a block of ice cream or related frozen product (referred to herein generally as an "ice cream product") in which a more complex pattern of colours is formed.
The pattern may depict an animal, as in the example described below, or any other object, animate or inanimate, ~ ~90~4 such as a person, a p]ant, a scene, a building, a flag or other emblem, a trophy, one or more letters or words, a trade mark, or any other distinctive representation that may or may not be partially or wholly surrounded by a border portion of the pattern.
To this end, the invention provides an extruder head consisting of (a) an elongate mould having (i) an outer peripheral wall conforming to the cross-sectional shape of the carton for receiving the carton thereon, and (ii) inner wall portions within said peripheral wall, said inner wall portions dividing the mould into a plurality of separate compartments defining said pattern, and (b) tube means for conveying streams of an ice cream product of at least two (preferably three) different colours to an inner end face of said mould for travel along said mould into the carton when said carton is mounted on the outer peripheal wall of the mould, whereby to form said block, (c) said tube means comprising (i) a main tube for conveying each of said streams from a respective ice cream product making machine, and (ii) a plurality of subtubes extending from each main tube to said inner end face of the mould, (iii) said sub-tubes being so sized and directed as to feed into each respective said compartment a said stream of the colour required for forming said pattern in an amount required to occupy the cross-sectional area of said compartment.
The extruder head will preferably be designed for three different colours of an ice cream product, and can even extend to a fourth or further colours, if desired.
Nevertheless, the invention can be used to form a pattern having only two colours, for example a representation of the Canadian flag. The invention enables the formation of a pattern of this type in which the colours are not simply placed side-by-side, as in the Neopo]itan style of packaging mentioned above, but are interwoven in a more complex pattern. Usually, but not necessary, one or more ~ 3~
colours w;]l surround, or nearly surround, another colour.
Apart from patterns like the Canadian flag where a central white bar portion will completely surround a central red portion depicting the maple leaf, the outline of many patterns will often be best set off by a peripheral surround or near-surround of another colour, as will be evident from the specific embodiment described below.

Description of the Embodiment _____________________________ The extruder head ~ receives an ice cream product in three different colours A, B and C from conventional ice cream making machines (not shown). The extruder head H
includes an elongate mould M over which in the conventional manner an empty carton (not shown) is placed to receive the extruded ice cream in the form of a block. The ~ ;~9~)~37!~
rectanqular shape of the mould M, as best seen in Figure 5, complements that of the carton which ~its slidingly over the outer periphery of the mould M as defined by an outer peripheral wall 10. Inside this outer wall 10 the mould is furnished with a main inner wall portion 11 that is shaped to define the outline of the required represent-ation, which, in the example shown, is the outline of a Panda bear. Within the main inner wall portion 11 there are various subsidiary inner walls portions 12 that serve 10 to divide the pattern into a plurality of separate compartments. In addition, inner wall portions 13, 14 and 15 form tubes that serve further to define small parts of the pattern.
All the wall portions 10 - 15, which together define 15 the pattern of colours to appear in the ice cream product block, continue in the same relationship to one a~other from the mouth 16 of the mould to a plate P3 that defines the inner end face of the mould, i.e. the cross-section of the mould remains uniform from its inner end to its mouth.
As indicated above, the invention is not limited to any particular pat~ern. By the same token the outer wall 10 of the mould need not necessarily be rectangular, but can be circular or any other shape that will fit the carton into which the ice cream is to be extruded.
The head H receives the ice cream product in colours A, B and C, in respective main tubes Al, Bl, Cl. These tubes are then each subdivided a number of times and appropriately interlaced to convey respective streams of the ice cream product to the inner end face P3 of the 30 mould M. For example, tube Al is joined by a removable clamp A2 to a further tube A3 (Figure la) which is then divided (Figure lb) into subtubes A4 - A9 that feed to respective holes A4 - A9 in the plate P3 as seen in Figure 5. Similarly, the tube Bl is divided into tubes B2 and B3.
35 Tube 82 is connected by a removable clamp B4 (Figure 3a) to a further tube B5 which is then divided into subtubes B6 -B10 (Figures lb and 3b) that feed to respective holes B6 -B10 in the plate P3 (Figure 5). The tube B3 is connected by a removable clamp Bll to a further tube B12 (Figure 4a) which is then divided into subtubes B13 - sl5 (Figures lb and 2b) that feed to respective holes B13 - B15 in the plate P3 (Figure 5). ~imilarly, the tube Cl is divided into tubes C2 and C3. The tube C2 is connected by a removable clamp C4 to a further tube C5 (Figure 4a) which is then further divided into subtubes C6 - C10 (Figure 3b) that feed to respective holes C6 - C10 in the plate P3 (Figure 5). The tube C3 is connected by a removable clamp Cll to a further tube C12 (Figure la) which is then divided into subtubes C13, C14 and C15 (Figure lb or 3b) that feed to respective holes C13, C14 and C15 in the plate P3 tFigure 5).
The tubes A3, B5, B12, C5 and C12 are supported in the orientation shown by a plate Pl, and the plates Pl and P3 are interconnected by a plate P2 to furnish the device with the necessary strength and rigidity.
The removable clamps play no part in the function of the device, being provided to enable it to be at least partially dismantled for cleaning. The tubes and subtubes will preferably be made of stainless steel.
Let us assume that colour A will be white, e.g.
vanilla; that colour B will be dark, e.g. chocolate; and that colour C will be red, e.g. strawberry. It will be seen from Fig~re 5, and from the finish product shown in Figure 6, that, in these circumstances, the rear back portion A10 of the bear pattern, which is formed in a compartment All of the mould fed by holes A4, A5 and A7, will be white. Also white will be the head portion A12 of the bear formed in a compartment A13 fed by holes A6, A8 and A9.
A forward portion B16 of the pattern, which is formed in a compartment B17 fed by holes B6, B7, B8 and B10, will ~0'37 be dark. A rear leg portion Bl8, which is formed in a compartment Bl9 fed by hole B9 will also be dark. In addition a dark ear portion s20 is formed in a compartment B21 supplied by the hole sl3, a dark eye portion B22 is formed in a compartment B23 supplied by the hole B14, and a dark nose portion B24 is formed in a compartment B25 supplied by the hole Bl5.
The remaining colour, red, will be supplied to border portions of the pattern formed respectively in compartments Cl7 and Cl8. The compartment Cl7 is supplied through holes C6 - ClO, and the compartment C18 is supplied through holes C13 to Cl5.
The diameters of the tubes, especially of the subtubes, and the cross-sections of the holes in the plate P3 through which they feed the ice cream product, together with the number and distribution of the holes in each of the compartments of the mould, are so adjusted, having regard to the shape and cross-sectional area of each compartment, that the correct quantity of ice cream product of each colour stream is fed to each compartment to form the finished product with little or no tendency for the stream in one portion of the pattern to flow laterally into an adjacent portion of the pattern.
If desired, the tubes leading to the mould, and especially the smaller subtubes, and/or the mould itself, can be externally chilled by suitable means (not shown) for maintaining the product at the best temperature for performing the extrusion process and forming the final block that is the objective.
The apparatus as described above will exert a certain amount of "back pressure" on the streams, i.e. a resistance to flow, resulting from the relatively small diameters of some of the tubes. The conventional wisdom in the art of ice cream packaging holds that such back pressure should be minimised to avoid loss of the air trapped in the ~ ~3U~:37~
product. It has been found, however, when operating an extruder head as illustrated in the drawings, that the degree of back pressure involved is not in fact a serious problem, and that a very satis~actory final product of S good quality can be obtained notwithstandin~ the relatively small diameter tubes through which the streams must be forced by an incoming pressure provided by the ice cream making machines.
