Definitions

• the location of piercing of the lid to accommodate the inflow and outflow is such that aqueous medium passing through the cartridge moves generally inwardly from the inlet to the outlet.
• Figure 14 is a perspective view from above of the inner member of Figure 12;
• Figure 15 is a perspective view from above of the inner member of Figure 12 in an inverted orientation;
• Figure 40 is another perspective view of the cartridge head of the machine of Figure 35 with some parts omitted for clarity;
• Figure 45 is a plan view of a beverage of the present invention comprising a barcode.
• the inner hub 52 is located at a lower position than the outer rim 51, resulting in the annular frame 41 having a sloping lower profile.
• the aluminium layer is 0.06 mm and the polypropylene layer is 0.025 mm thick.
• This laminate is particularly advantageous as it has a high resistance to curling during assembly.
• the laminate 5 may be pre-cut to the correct size and shape and subsequently transferred to the assembly station on the production line without undergoing distortion. Consequently, the laminate 5 is particularly well suited to welding.
• Other laminate materials may be used including PET/Aluminium/PP, PE/EVOH/PP, PET/metallised/PP and Aluminium/PP laminates.
• Roll laminate stock may be used instead of die cut stock.
• Assembly of the cartridge 1 involves the following steps : a) the inner member 3 is inserted into the outer member 2 ; b) the filter 4 is cut to shape and placed onto the inner member 3 so to be received over the cylindrical funnel 40 and come to rest against the annular frame 41; c) the inner member 3, outer member 2 and filter 4 are joined by ultrasonic welding; d) the cartridge 1 is filled with one or more beverage ingredients; e) the laminate 5 is affixed to the outer member 2. These steps will be discussed in greater detail below.
• the outer member 2 is orientated with the open bottom
• the laminate 5 is then affixed to the outer member 2 by forming a weld 126 around the periphery of the laminate 5 to join the laminate 5 to the lower surface of the outwardly extending flange 35.
• the ⁇ weld 126 is extended to seal the laminate 5 against the lower edge of the cylindrical wall 27 of the inlet chamber 26.
• a weld 125 is formed between the laminate 5 and the lower edge of the outer tube 42 of the cylindrical funnel 40.
• the laminate 5 forms the lower wall of the filtration chamber 130 and also seals the inlet chamber 26 and cylindrical funnel 40.
• a small gap 123 exists prior to dispensation between the laminate 5 and the lower edge of the discharge spout 43.
• a variety of welding methods may be used, such as heat and ultrasonic welding, depending on the material characteristics of the laminate 5.
• the aperture size is fixed plus or minus 0.02 mm 2 .
• Hairs, fibrils or other surface irregularities can be provided within or at . the exit of the eductor to increase the effective cross-sectional area which has been found to increase the degree of air entrainment .
• the hollow inwardly directed cylindrical extension 18 of the outer member 2 of the third version has a larger overall diameter as shown in Figure 20.
• the diameter of the first portion 19 is typically between 16 and 18 mm compared to 13.2 mm for the outer member 2 of the previous versions.
• the first portion 19 is provided with a convex outer surface 19a, or bulge, as most clearly shown in Figure 20, the function of which will be described below.
• the diameter of the third portions 21 of the cartridges 1 are however the same resulting in the area of the shoulder 32 being greater in this, the third version of the cartridge 1.
• the volume of the cartridge 1 when assembled is 32.5 ml ⁇ 20%.
• the construction of the cylindrical funnel 40 of the inner member 3 is the same as in the first version of cartridge 1 with an outer tube 42, discharge spout 45, annular flange 47 and support webs 49 being provided.
• the discharge spout 45 is shaped with an upper frusto-conical section 92 and a lower cylindrical section 93.
• the annular frame 41 is replaced by a skirt portion 80 which surrounds the cylindrical funnel 40 and is joined thereto by means of eight radial struts 87 which adjoin the cylindrical funnel 40 at or near the annular flange 47.
• a cylindrical extension 81 of the skirt portion 80 extends upwardly from the struts 87 to define a chamber 90 with an open upper face.
• liquid coffee is contained in the cartridge 1 with a viscosity of between 70 and 2000mPa at ambient and between 80 and 5000mPa at 0°C where the coffee has a total solids level of between 40 and 70%.
• a fourth version of cartridge 1 is shown in Figures 30 to 34.
• the fourth version of the cartridge 1 is particularly designed for use in dispensing liquid products such as concentrated liquid milk.
• Many of the features of the fourth version of the cartridge 1 are the same as in the previous versions and like numerals have been used to reference like features. In the following description the differences between the fourth and previous versions will be discussed. Common features which function in the same manner" will not be discussed in detail.
• Fresh semi-skimmed milk contains approximately 1.6% fat and 10% total solids.
• the concentrated liquid milk preparations of the present invention contain between 3 and 10% fat and 25 to 40% total solids. In a typical example, the preparation contains 4% fat and 30% total solids.
• the concentrated milk preparations are suitable for foaming using a low pressure preparation machine as will be described below. In particular, foaming of the milk is achieved at pressures below 2 bar, preferably approximately 1.5 bar using the cartridge of the fourth embodiment described above .
• the cartridge of the fourth embodiment is also advantageous in dispensing liquid coffee products.
• the materials of the cartridges described above may be provided with a barrier coating to improve their resistance to oxygen and/or moisture and/or other contaminant ingress .
• the barrier coating may also improve the resistance to leakage of the beverage ingredients from within the cartridges and/or reduce the degree of leaching of extractibles from the cartridge materials which might adversely affect the beverage ingredients.
• the barrier coating may be of a material selected from the group of PET, Polyamide, EVOH, PVDC or a metallised material.
• the barrier coating may be applied by a number of mechanisms including but not limited to vapour deposition, vacuum deposition, plasma coating, co-extrusion, in-mould labelling and two/multi-stage moulding.
• the variables for the operational parameters are stored in the memory.
• the cartridge 1 comprises a code provided on or in the cartridge 1 representing the operational parameters required for optimal dispensation of the beverage in that cartridge 1.
• the code is in binary format and comprises a plurality of data bits corresponding to the variables stored in the control processor memory. Table 3 illustrates how 13 bits of data can be used to represent the necessary variables for the operational parameters described above .
• the resilient sleeves 282c provide a resistance to re-opening of the upper part 256 since a minimum force is required to compress the sleeves 282c sufficiently to move the third pivot points 286 back into line with the datum line joining the first and second pivot points 283, 285.
• the interengagement of the- hook members 287 and the bosses 259 prevents separation of the upper and lower parts other than by rotation of the clamping lever. This is useful in preventing opening of the cartridge head 250 during operation when the cartridge head 250 is subject to internal pressurisation.
• the operating cycle comprises the steps of cartridge recognition and the discharge cycle.
• Cartridge recognition is performed by the optical cartridge recognition means 252 as described above assuming that the outputs from the cartridge sensor and lock sensor are satisfactory.
• the operational parameters of the machine 201 are adjusted by the control processor.
• the discharge cycle is then automatically commenced.
