Cartridge for preparation of drinks
The present invention relates to a cartridge for the preparation of beverages and, in particular, to a sealed cartridges, which are formed from essentially airtight and waterproof materials and contain one or more ingredients to prepare drinks.
Previously been proposed to seal the ingredients to prepare drinks in a separate airtight packaging. For example, the known cartridges or capsules containing compacted ground coffee for use in some machines for making coffee, usually called machines espresso. When preparing coffee using these machines cartridge with coffee is placed in the cooking chamber and the hot water passes through the cartridge at a relatively high pressure, thus removing the aromatic components of the ground coffee with getting a coffee drink. Typically, such machines operate at pressures above 6 x 105PA. Machines of the type described in the present time are relatively expensive, since the details of such a machine, such as water pumps and seals must withstand high pressure.
In the application WO 01/58786 described cartridge for the preparation of drinks, which operates at a pressure generally in the range from 0.7 to 2.0 x 105PA. However, the cartridge is designed for use in machines for preparing beverages for Torgo the CSO or the industrial market and is relatively expensive. Therefore, the cartridge for the preparation of drinks, there is a requirement that the cartridges and the machine for making the drink should be acceptable for the domestic market from the point of view of cost, performance and reliability.
The cartridge WO 01/58786 has an essentially rectangular shape. Therefore, layer ingredients of the drink is essentially rectangular in shape. Water enters the compartment containing the beverage ingredients through slots located down the long sides of the branch. Brewed drink prepared from the ingredients of the drink is collected in the chamber, placed at one end of the cartridge. Found that the portion of water flowing through the cartridge, are layered drink ingredients different times depending on through which slit the water was admitted to the Department. This can result in uneven extraction and the output of the ingredients of the drink and within a single cartridge and between the cartridge, following each other. In addition, at the stage of preliminary wetting, when the water is injected in the Department to impregnate the ingredients of the drink, the degree of wetting can be varied along the length of the cartridge.
In JP 2000093309 described A cartridge with a cylindrical wall, a closed upper and lower ends of the aluminum foil. When used in the top of the foil about the scarfing inlet, in order to inject water into the Central column from which water flows down through the layer of coffee, and then through filter paper into a cylindrical chamber for collection. The final hole for a drink form the perforation of the bottom film. This cartridge is relatively complex, in particular because it requires the camera to collect, which must have size at least equal to the size of the filter paper. Requirement gathering chamber at the lower end of the cartridge also increases the overall size of the cartridge. In addition, the use of the cartridge is relatively complex, since the input and output openings of the cartridge must be formed at the opposite ends of the cartridge.
Accordingly, the present invention provides a cartridge containing one or more ingredients for the drink and formed from essentially air - and water-impermeable materials, the cartridge contains or may form at least one inlet for supplying aqueous medium into the cartridge, and at least one outlet, and the aqueous medium through the cartridge runs mainly radially downward from at least one inlet to the at least one exhaust hole.
It is clear that under used herein, the term "cartridge" refers to any package, pin is iner, package, cassette, which contains one or more beverage ingredients as described. The cartridge may be rigid, semi-rigid or flexible.
The cartridge according to the invention contains one or more ingredients suitable for the formation of a drink. The drink can be, for example, coffee, tea, chocolate or drink based on milk containing milk. Ingredients for the beverage can be powdered, blended on the basis of leaf or liquid. Ingredients for the beverage can be insoluble or soluble. Examples include roasted coffee beans, ground coffee, leaf tea, dry and liquid cocoa powder, liquid milk-based drinks and concentrated fruit juices.
The cartridge may include a chamber containing one or more ingredients for the drink. This camera can contain at least one inlet opening, inward.
Radial direction of the flow in this chamber provides increased efficiency of extraction of the ingredients of the drink with the passage of the water environment. Preferably, the cartridge has a disk shape. Preferably, an inlet for feed water medium in the cartridge is located at the periphery of the cartridge or around it. Peripheral collector allows aqueous medium to enter the chamber containing the ingredients for the drink, simultaneously from multiple sites, the pre is respectfully equidistant from each other around the circumference of the disc-shaped cartridge. Preferably, the cartridge further contains peripheral reservoir, separated from the camera storage wall containing many inward openings. Preferably, the many inward openings directed radially inward. The cartridge may contain an opening through which one or more beverage ingredients may enter the camera hole is closed by a lid, which, when used, can pierce to take the inflowing stream of water environment and stemming the flow of the beverage resulting from interaction of the aqueous medium and one or more beverage ingredients in the above-mentioned chamber.
Peripheral collector preferably is located on the edge of the cartridge and communicated with the inlet. Therefore, the ingredients of the drink faster wetted in the initial stages of the business cycle and, in addition, the aquatic environment is more effectively used at the stage of wetting. In addition, the length of the flow path through the chamber in a generally constant, regardless of the openings through which water enters the chamber. It is expected that this will lead to improved consistency and strength of the extract and faster workflow. In addition, the length of the flow path through the chamber is minimized for a given volume compared to rectangular CT the ridge. This leads to minimize the back pressure generated in the cartridge, since the length of the flow path is relatively short compared to the rectangular chamber of the same volume and thickness.
Preferably, the peripheral manifold is located on the edge of the cartridge. Preferably, the wall contains 3-40 holes. In one embodiment, the wall contains 3-5 holes. In another embodiment, the wall contains 35-40 mentioned holes.
Preferably, each hole has a cross-sectional area from 0.45 to 0.65 mm2.
Preferably, the cartridge includes an inlet chamber, a chamber connected with the peripheral manifold. Preferably, the inlet chamber communicates with the peripheral manifold through one or more apertures formed in the wall of the intake chamber.
In one embodiment, the cartridge further comprises a filter positioned between the storage chamber and at least part of the bottom side of the top of the cartridge, between the filter and the top of the cartridge is formed of one or more passages that communicate with the outlet, the flow path of the beverage from the inlet to the outlet passes up through the filter in one or more passes.
Preferably, the cartridge includes an outer element and an inner element connected during Assembly with the outer element and the inner and the deposits of the element forms the outlet of the cartridge. Preferably, the inner element contains the discharge spout forming a discharge outlet.
The inlet and/or outlet may be closed essentially airtight and waterproof material before formation when using the inlet and/or outlet openings in the cartridge. Preferably, the inlet and/or outlet is closed essentially airtight or waterproof laminated material.
The external and/or internal element can be formed from high density polyethylene. The external and/or internal element can be formed by injection molding.
It is also possible to cassette, containing a number of cartridges, where each cartridge is made as described above, while the percentage output of the beverage produced from one or more of the ingredients contained in the cartridge, is in the range of 1.0 standard deviation.
Preferably, the wall contains 3-40 holes. In one embodiment, the wall contains 3-5 holes. In another embodiment, the wall contains 35-40 mentioned holes.
The cartridge may contain an inlet chamber, a chamber connected with the inlet and peripheral manifold. Preferably, muskateer reported with peripheral reservoir through one or more apertures, formed in the wall of the intake chamber.
The cartridge, in addition, may contain a filter disposed between the camera and at least part of the bottom side of the top of the cartridge, and between the filter and the top of the cartridge is formed of one or more passages communicated with the outlet, the flow path of the beverage from the inlet to the outlet passes up through the filter in one or more passes.
The cartridge preferably includes an outer element and an inner element connected during Assembly with the outer element, the inner element forms the outlet of the cartridge.
Details of the internal element and the external element is easier to sterilize before Assembly, when they are separated. When the parts are assembled, there is formed a series of meandering channels with a small hole that cannot be effectively sterilized by known methods. The sterilization of the parts is of particular advantage when cartridges are used to issue milk-based drinks. Can be used in the locking device, which provides a fast and secure way to connect the inner element and the outer element. Its advantage is that the locking device eliminates the use of glue or other adhesive in the inner hour and a cartridge which will contact the ingredients of the drink.
Preferably, the inner element contains the discharge spout forming the outlet. Preferably, the inner element contains the discharge spout. The discharge spout serves to guide pour drink into a receiver, such as a Cup. The discharge spout allows you to avoid unnecessary spraying or splashing of the beverage and is also useful for control of flow of the beverage when it is moved from the cartridge into the receiver. For example, the discharge spout may be in the form of reducing the degree of turbulence reported to drink, to avoid a possible decrease in the number of bubbles contained in the drink. Also preferably, the cartridge contains the discharge spout, and is not provided with a separate discharge spout in the car to make the drink. Thus, there is no danger of mutual contamination of one drink another drink between work cycles, because each outlet spout will only be used once and then replaced with the cartridge. Also preferably, the beverage is discharged through the outlet spout will not contact with the exhaust mechanism of the machine for preparing beverages, thereby eliminating contamination of the machine for preparing a drink. Preferably, the discharge spout issue is lnen in one piece with the inner element. Preferably, the outlet spout and the inner element is molded or otherwise executed in a single node, which reduces the manufacturing cost of the cartridge and reduces the number of parts required for Assembly.

The inlet 121 and outlet 122 original sealed laminated material 5 and is opened when using due to perforation or cutting of the laminated material 5. The path of flow of the beverage is determined by the spatial relationship between the outer element 2, inner member 3 and the laminated material 5, as discussed below.
The first version of the cartridge 1, described below, is shown in figure 1-11. The first version of the cartridge 1, in particular, is intended for use when issuing such filtered products, such as roast and ground coffee or leaves the th tea. However, this variant of the cartridge 1 and the other options described below can be used with other products, such as chocolate, coffee, tea, sweeteners, spices, alcoholic drinks, flavoured milk, fruit juices, fruit drinks, sauces and desserts.
As can be seen from figure 5, the cartridge 1 has a General circular or disc shape, and the diameter of the cartridge 1 is significantly larger than its height. The major axis X passes through the center of the outer member, as shown in figure 1. Usually, the overall diameter of the outer member 2 is 74,5 mm+20%, and its total height is 16 mm+3 mm is Usually the volume of the assembled cartridge is 30.2 ml+20%.
The external element 2 usually contains a Cup-shaped housing 10 with the curved annular wall 13, a closed upper part 11 and an open bottom 12. The outer diameter of the element 2 in the upper part 11 is smaller than the diameter of the lower part 12 extending downward annular wall 13 as it moves from the closed top 11 to the open bottom 12. The annular wall 13 and a closed upper portion 11 together define a receiver with an internal space 34.

As best shown in figure 2, the cylindrical protruding frequent the 18 includes a stepped profile with the first, the second and third sections 19, 20 and 21. The first section 19 has a right circular cylindrical shape. The second section 20 has the shape of a truncated cone and tapers down. The third section 21 is another right circular cylinder and a closed bottom end 31. The diameter of the first, second and third sections 19, 20 and 21 speed decreases so that the diameter of the cylindrical protruding part 18 is reduced as it moves from the upper part 11 to the closed bottom end 31 of the cylindrical protruding part 18. On the cylindrical protruding part 18 at the connection point between the second and third sections 20 and 21 formed essentially horizontal shoulder 32.
On the external element 2 are closer to the bottom 12 is formed continuing to the outside shoulder 33. Continuing outward shoulder 33 forms a secondary wall 15, a coaxial annular wall 13 so as to define the boundaries of the ring road, which forms the collector 16 between the secondary wall 15 and the annular wall 13. Collector 16 passes around the circumference of the outer member 2. In the annular wall 13 includes a number of slots 17 on the same level with the reservoir 16 to provide communication for gas and liquid between the collector 16 and the inner space 34 of the outer member 2. As shown in figure 3, the slits 17 are made in the form of vertical slots in the annular wall 13. Provided by from 2 to 40 slots. In the illustrated embodiment, thirty-seven slots 17 are essentially equidistant from each other around the circumference of the manifold 16. Slit 17 preferably have a length between the 1.4 and 1.8 mm is Usually the length of each slit is 1.6 mm, which is 10 % of the total height of the outer member 2. The width of each slit is from 0.25 to 0.35 mm is Usually the width of each gap is 0.3 mm, the Width of the slits 17 is small enough to prevent the passage through it of the ingredients of the beverage in the reservoir 16 during storage or use.
Intake chamber 26 formed in the outer element 2 at the periphery of the outer member 2. Provided by cylindrical wall 27, as best seen in figure 5, which forms inside the inlet chamber 26 and separates the inlet chamber 26 from the inner space 34 of the outer member 2. Cylindrical wall 27 has a closed upper end 28, which is formed on a plane perpendicular to the major axis X, and an open lower end 29, coplanar lower part 12 of the outer member 2. Intake chamber 26 communicates with the reservoir 16 through the two slots 30, as shown in figure 1. Alternatively, communication between manifold 16 m inlet chamber 26 can be used from one to four slits.
The lower end protruding outward of the shoulder 33 provided with protruding outward flange 35, which passes perpe dicosmo major axis X. Typically, the flange 35 has a width of between 2 and 4 mm portion of the flange 35 is increased for forming a handle 24 which may be used to hold the outer member 2. The handle 24 is equipped directed upward edge 25 for better grip.
The outer member 2 is made in a single piece of high-density polyethylene, polypropylene, polystyrene, polyester or laminated material from one or two of these materials. A suitable polypropylene is the number of polymers available from DSM UK Limited (Redditch, UK). The outer element may be opaque, transparent or translucent. The method of manufacture may be injection molding.
The internal element 3, as shown in Fig.7-10, contains an annular frame 41 and protruding downward cylindrical funnel 40. The major axis X passes through the center of the inner element 3, as shown in Fig.7.
As best seen in Fig, the annular frame 41 includes an external rim 51 and the inner sleeve 52, United ten located at equal distance apart radial ridges 53. The inner sleeve 52 made in one piece with the cylindrical funnel 40 and acts from it. Filtration openings 55 formed in the annular frame 41 between the radial ridges 53. The filter 4 is located on the annular frame 41 so as to close the filtration openings 55. The filter preferably is accomplished from a material with high strength in the wet state, for example, from non-woven fibrous material of polyester. Can be used and other materials, including waterproof pulp material, such as cellulosic material containing-woven paper fibers. Woven paper fibers can be mixed with the fibers of polypropylene, polyvinyl chloride and/or polyethylene. The inclusion of these plastics in the cellulosic material makes this cellulose material thermovalve. The filter 4 can also be treated or coated with a material that is activated by heat and/or pressure so that it can be firmly attached thus to the annular frame 41.
As shown in section 7, the inner sleeve 52 is located below the outer rim 51, causing the annular frame 41 is inclined down the profile.
The upper surface of each jumper 53 provided with a vertical partition 54 which divides the free space above the annular frame 41 on many passages 57. Each passage 57 is bordered on each side by a partition wall 54 and the bottom surface with the filter 4. The passages 57 pass from the outer rim 51 down to the cylindrical funnel 40 and open it in the holes 56, bounded by the inner ends of the partitions 54.
The cylindrical funnel 40 includes an outer tube 42 surrounding the inner discharge spout 43. The outer tube 42 of the will formed the outer part of the cylindrical funnel 40. The discharge spout 43 is connected to the outer tube 42 on the upper end of the discharge spout 43 through the annular flange 47. The discharge spout 43 contains an inlet opening 45 at the upper end of which communicates with the holes 56 of the passages 57, and the exhaust port 44 at the lower end, through which the beverage is poured into a Cup or other receiver. The discharge spout 43 contains a plot 48 in the form of a truncated cone at the upper end and the cylindrical section 58 at the lower end. The cylindrical section 58 may have a slight constriction, such that it tapers to the outlet 44. Section 48 in the form of a truncated cone helps towards drink from the passages 57 down to the exhaust hole 44 without the occurrence of turbulence in the drink. The upper surface 48 in the form of a truncated cone provided with four supporting walls 49, reversename around the circumference of the cylindrical funnel 40. Reference partitions 49 define the boundaries of the channels 50 between them. The upper edge of the supporting partitions 49 are on the same level with each other and perpendicular to the major axis X.
The internal element 3 can be made in a single piece of polypropylene or similar material, as described above, and by injection molding in the same way as an external item 2.
Alternatively, the inner element 3 and/or external e is ement 2 can be made of biodegradable polymer. Examples of suitable materials include biodegradable polyethylene (for example, SPITEK company Symphony Environmental, Borehamwood, UK), the biodegradable polyetherimide (for example, BAK 1095 company Symphony Environmental), polylactic acid (PLA firm Cargil, Minnesota, USA), polymers based on starch, cellulose derivatives and polypeptides.
Laminated material 5 is formed from two layers, the first layer of aluminum and a second layer of cast polypropylene. The aluminum layer has a thickness of between 0.02 and 0.07 mm Layer of cast polypropylene has a thickness of between 0.025 and 0,065 mm In the embodiment, the aluminum layer has a thickness of 0.06 mm, and a layer of cast polypropylene has a thickness of 0.025 mm, This laminated material is particularly preferred because it has a high resistance to twisting during Assembly. In the laminated material 5 can be pre-cut to the correct size and shape, and then submitted to the Assembly station of the production line, without subjecting it to deformation. Therefore, the laminated material 5 is particularly suitable for welding. Can be used and other laminated materials, including polyethylene terephthalate PET/Aluminum/polypropylene PP, polyethylene PE/Vinyl ethylene EVOH/ polypropylene PP, polyethylene terephthalate PET/metalized/ polypropylene PP and Aluminum/ polypropylene PP layers. Instead what about the cut blanks can be used a roll of the laminated material.
The cartridge 1 can be closed by a rigid or semi-rigid cover instead of the laminated material.
The cartridge Assembly 1 includes the following stages:
the internal element 3 is inserted into the outer element;
cut off filter 4 desired shape and placed on the inner element 3 so as to position it over the cylindrical funnel 40 and supported on the annular frame 41;
the internal element 3, the outer member 2 and the filter 4 are combined by ultrasonic welding;
the cartridge 1 is filled by one or more beverage ingredients;
laminated material 5 is attached to the outer element 2.
These stages more discussed below.
The outer member 2 are oriented so that the open bottom portion 12 facing up. Then, the inner element 3 is inserted into the outer element 2 so that the outer rim 51 came with a loose fit in the axial continuation of the 14 top 11 of the cartridge 1. The cylindrical protruding portion 18 of the outer member 2 at the same time placed in the upper part of the cylindrical funnel 40 of the inner element 3. The third section 21 of the cylindrical protruding part 18 is located inside the cylindrical funnel 40 with a closed bottom surface 31 of the cylindrical protruding part 18, leaning on walls 49 of the inner element 3. The filter 4 is then placed over the inner element 3 thus, Thu the filter material is in contact with the annular rim 51. Then, using ultrasonic welding filter 4 is attached to the inner element 3 and at the same time, on the same stage, the internal element 3 is attached to the outer element 2. The internal element 3 and the filter 4 are welded together along the outer rim 51. The internal element 3 and the outer member 2 are held together by welded seams on the outer rim 41, and the upper edges of the partitions 54.
As better shown in 11, the outer member 2 and the inner element 3, when they are connected, define the boundaries of the space 130 in the internal space 120 under the annular flange 41 and the outside cylindrical funnel 40, forming the filtration chamber. Filtration chamber 130 and the passages 57 above annular frame 41 is divided by the filter paper 4.
Filtration chamber 130 contains one or more ingredients 200 drink. One or more beverage ingredients packaged (sealed) in the filtration chamber 130. Drink filtered type this ingredient is usually roasted and ground coffee or leaf tea. The stuffing ingredients of the drink in the filtration chamber 130 may vary as desired. Usually to get coffee filtration chamber contains from 5.0 to 10.2 grams of roasted and ground coffee in the filter layer thickness is usually from 5 to 14 mm Inner space 120 may contain od is about or more bodies, such as balls, move freely in the internal space 120 to facilitate mixing, creating turbulence and destroying the sediment drink ingredients during the production of the beverage.
Laminated material 5 is then affixed to the outer element 2 through the formation of a welded joint on the periphery of the laminated material 5 for its accession to the bottom surface of the protruding outward flange 35. Welded connection 126 is located so as to tightly attach the laminated material 5 to the lower edge of cylindrical wall 27 of the inlet chamber 26. In addition, the welded joint 125 is formed between the laminated material 5 and the bottom edge of the outer tube 42 of the cylindrical funnel 40. Laminated material 5 forms the lower wall of the filtration chamber 130 and seals the inlet chamber 26 and the cylindrical funnel 40. However, between the laminated material 5 and the lower edge of the discharge spout 43 to issue exists a small gap 123. Can be used in a variety of welding methods, such as welding by heat and ultrasonic welding, depending on the characteristics of the laminated material 5.
Preferably, the inner element 3 is located between the outer element 2 and the laminated material 5. The internal element 3 is made of a relatively hard mA is Arial, such as polypropylene. As such, the internal element 3 forms a load bearing element, which holds the laminated material 5 and the outer member 2 at a distance from each other when the cartridge 1 is influenced by pressure. Preferably, when using the cartridge 1 applies pressure between 130 and 280 N. This pressure serves to prevent breakage of the cartridge under the action of internal pressure and to compress the inner element 3 and the outer member 2 together. This ensures the constancy of the internal dimensions of the passages and holes in the cartridge 1 and cannot be modified when the pressure in the cartridge 1.
To use the cartridge 1 is first inserted into the machine for preparing a drink and the inlet 121 and outlet 122 are opened under the action of these elements of the machine for preparing a drink, which pierce and bent laminated material 5. Aqueous medium, usually water, is supplied under pressure into the cartridge 1 through the inlet 121 to the suction chamber 26 under the pressure of 0.1-2.0 bar. From there the water is directed through the slit 30 and the collector 16 in the filtration chamber 130 of the cartridge 1 through the number of gaps 17. Water is directed radially inward through the filter chamber 130 and is mixed with the ingredients 200 drink. Although the NGO water is directed up through the ingredients of the drink. Drink, formed as a result of the passage of water through the ingredients of the beverage passes through the filter 4 and the filter hole 55 in the passages 57 located above annular frame 41. Sealed fastening of the filter 4 on the jumper 53 and the welding of the rim 51 of the external element 2 ensures that the liquid will not find a shorter path and all the beverage passes through the filter 4.
Then the drink is flowing down through the radial passages 57 formed between the partitions 54, and through the openings 56 in the cylindrical funnel 40. The beverage passes through the channels 50 between the support walls 47 and down the exhaust nozzle 43 to the outlet 44 from which the beverage is poured in such a receiver, as a Cup.
Preferably, a machine for making a beverage contains a means for blowing air, which compressed air is supplied through the cartridge 1 at the end of the working cycle, to blow away the rest of the drink into the sink.
The second variant of the cartridge 1 shown in Fig-18. The second variant of the cartridge 1, in particular, is intended for use when issuing products such as espresso, such as roasted and ground coffee, when it is desirable to obtain a beverage with a foam of small bubbles, known as "crumb" (Italian : "foam"). Many of the signs of the second variant of the cartridge 1 are the same as in the first embodiment, and to indicate analogion the x signs used the same position. In the following description will discuss the differences between the first and second options. Common signs that perform similar functions, detail will not be considered.
The external element 2 has the same design as in the first embodiment of the cartridge 1, as shown in Fig.1-6.
The annular frame 41 of the internal element 3 is the same as in the first embodiment. The filter 4 is located on the annular frame 41 so as to close the filtration openings 55. The outer tube 42 of the cylindrical funnel 40 is the same as before. However, there are some differences in the design of the inner element 2 of the second variant in comparison with the first option. As shown in Fig, the discharge spout 43 is equipped with a partition wall 65, which continues up part of the discharge spout 43 from the outlet 44. The partition wall 65 helps to prevent spraying and/or splashing of the beverage, when he comes out of the discharge spout 43. The profile of the discharge spout 54 is also different and represents a stepped profile with a distinct curve 66 at the upper end of the tube 43.
Provides a rim 67, protruding upward from the annular flange 47 which connect the outer tube 42 with the discharge spout 43. Rim 67 surrounds the inlet 45 to the discharge spout 43 and forms an annular channel 69 between the rim 67 and the upper part of the outer tube 42 of the Rim 67 provided inward of the shoulder 68. At one point on the circumference of the rim 67 has a hole 70 in the form of a slit, which extends from the upper edge of the rim 67 to a point slightly below the level of the shoulder 68, as best seen in Fig and 13. The slit has a width of 0.64 mm
In the annular flange 47 has a hole 71 for receiving the air, perifericheskie aligned with the hole 70, as shown in Fig and 17. The hole 71 passes through the flange 47 so as to provide communication between a point above the flange 47 and the free space under the flange 47 between the outer tube 42 and the discharge spout 43. Preferably, and as shown, the hole 71 contains the upper portion 73 in the shape of a truncated cone and the lower cylindrical section 72. The hole 71 is usually arranged through a pin of the mold. Tapering profile of the hole 71 facilitates the separation of the mold from the cast in the shape of the product. The wall of the outer tube 42 near the hole 71 is shaped to form a groove 75, which leads from the opening 71 to the inlet 45 of the discharge spout 43. As shown in Fig, beveled shoulder 74 formed between the hole 71 for air and chute 75, to ensure that the jet of the beverage coming out of the slit 70, will not fall directly on the top surface of the flange 47 in the immediate vicinity of the hole 71 for air.
The Assembly procedure of the second variant of the cartridge 1 analogs is ICNA the Assembly of the first option. However, there are a few differences. As shown in Fig, the third section 21 of the cylindrical protruding part 18 is located inside the supporting rim 67 and not on the supporting walls. The shoulder 32 of the cylindrical protruding part 18 between the second portion 20 and the third section 21 rests on the upper edge of the support rim 67 of the inner element 3. Thus is formed a transition zone 124 between the inner member 3 and the outer element 2, which contains the mechanical seal between the cylindrical protruding part 18 and the supporting rim 67, continuing around almost the entire circumference of the cartridge 1. The seal between the cylindrical protruding part 18 and the supporting rim 67 is not tight, since the slit 70 in the bearing rim 67 passes through the supporting rim 67 and down to a point slightly below the shoulder 68. Therefore, the interaction between the cylindrical protruding part 18 and the supporting rim 67 converts the slot 70 in the hole 128, as best shown in Fig, providing the message for gas and liquid between the annular channel 69 and the discharge spout 43. The hole usually has a width of 0.65 mm and a length of 0,69 mm
The second version of the cartridge 1 on the issue of the drink is similar to the first option, but with some differences. As before, the flow of the beverage in the filtration chamber 130 includes a radial component from the input slit 17 of napervile cartridge 1 to the discharge spout 43 in the center of the cartridge 1. Drink in the radial passages 57 flows down the passages 57 formed between the partitions 54, and through the openings 56 in the annular channel 69 of the cylindrical funnel 40. From the annular channel 69 drink is supplied under pressure through the opening 128 through the back pressure of the drink, going in the filtration chamber 130 and the passages 57. The beverage thus ejected through the opening 128 in the form of strong thin stream into the expansion chamber formed by the upper end of the discharge spout 43. As shown in Fig, a jet of the beverage passes directly over the hole 71 for air. Upon receipt of the drink in the discharge spout 43 the pressure of the jet of the beverage falls. As a result, the air is mixed with the jet of the beverage, forming a multitude of small air bubbles as the suction of air through the opening 71. A jet of the beverage coming out of the hole 128 is sent down to the outlet 44, where the drink is poured into the receiver, such as a Cup, and air bubbles form the desired foam. Thus, the hole 128 and the hole 71 together form the ejector entrainment of air into the drink. The flow of beverage into the ejector should be maintained as much as possible homogeneous to reduce pressure losses. Preferably, the walls of the ejector must be made concave to reduce losses due to the "wall" of friction. Admission to RA the measures of the hole 128 is small. Preferably, the hole size is fixed, plus or minus 0.02 mm2. Inside or at the outlet of the ejector may be provided hairs, threads or other surface irregularities to increase the usable square cross-section, which, as it turns out, increases the degree of entrainment of air.
The third variant of the cartridge 1 shown in Fig-29. The third variant of the cartridge 1, in particular, is intended for generation of soluble products which can be in the form of a powder, liquid, syrup, gel, or other similar form. Soluble product is dissolved aqueous medium, such as water, or forms in her suspension, when in use, the water passes through the cartridge 1. Examples of beverages include chocolate, coffee, milk, tea, soup or other dehydrated or water-soluble products. Many features of the third version of the cartridge 1 are the same as in previous versions, for the same signs used in the same position. In the following description will discuss the differences between the third and previous versions. Common signs that function in a similar manner, the details will not be considered.
Compared with the external element 2 previous versions hollow inward protruding portion 18 of the outer member 2 of the third variant has a larger overall diameter than shown is on Fig. In particular, the diameter of the first section 19 is typically from 16 to 18 mm, compared with 13.2 mm in the case of the outer member 2 of the previous options. In addition, the first portion 19 provided with a convex outer surface 19a or bulge, best shown in Fig, the function of which will be described below. The third diameter sections 21 of the cartridge 1, however, is the same that leads to the fact that the area of the shoulder 32 more in this third embodiment, the cartridge 1. Typically, the volume of the cartridge 1 in the assembled state is 32.5 ml+20%.
The number and position of the slits in the lower end of the annular wall 13 is also different. Provided by from 3 to 5 slots. In the variant shown in Fig, there are four slits 36, ravnovesnye around the circumference of the manifold 16. The slit 36 is slightly wider than in previous versions of the cartridge 1, and have a width of between 0.35 and 0.45 mm, preferably of 0.4 mm
In other respects, the external elements 2 cartridges 1 are the same.
The design of the cylindrical funnel 40 of the inner element 3 is the same as in the first embodiment of the cartridge 1 with the outer tube 42, the discharge spout 45, annular flange 47 and the supporting walls 49. The only difference is that the discharge spout 45 is shaped with an upper section 92 in the form of a truncated cone and the lower cylindrical section 93.
In protivopolojna is here previous versions, and as shown in Fig-28, the annular frame 41 is replaced skirt section 80, which surrounds the cylindrical funnel 40 and attached thereto by eight radial arms 87 which are adjacent to the cylindrical funnel 40 at the location of the annular flange 47, or near it. The cylindrical protruding portion 81 skirt section 80 passes upward from the bracket 87, forming a chamber 90 with an open top. The upper rim 91 of the cylindrical protruding part 81 has a curved profile, as shown in Fig. The annular wall 82 of the skirt section 80 passes down from the brackets 87 with the formation of the annular channel 86 between the skirt section 80 and the outer tube 42.
The annular wall 82 includes at the lower end of the outer flange 83, which is perpendicular to the major axis X. the Rim 84 continues downward from the lower surface of the flange 83 and contains five holes 85, rownorzednych circumferentially around the rim 84. Thus the rim 84 fitted with a toothed lower profile.
Between brackets 87 are provided holes 89, providing communication between the chamber 90 and the annular channel 86.
The Assembly procedure of the third variant of the cartridge is similar to the Assembly of the first option, but with some differences. The outer member 2 and the inner element 3 together tight fit, as shown in Fig, and held together by zaselku is the existing device, instead of welding. After connecting these two elements inward of the cylindrical protruding portion 18 enters the upper cylindrical protruding part 81 skirt section 80. The internal element 3 is held in the outer element 2 through the friction clutch convex outer surface 19a of the first section 19 of the cylindrical protruding part 18 with the bent rim 91 of the upper cylindrical protruding part 81. When the inner element 3 located in the outer element 2, the mixing chamber 134 is located on the outside of skirt section 80. The mixing chamber 134 contains ingredients 200 drink before issuing. It should be noted that the four inputs 36 and five holes 85 are located on the periphery of the offset (staggered) with respect to each other. The radial position of the two parts relative to each other is not required to determine or fix during Assembly, since the use of four inlet holes 36 and five holes 85 ensures that between the inputs and the holes will not match, whatever the relative rotary position of the elements.
One or more beverage ingredients Packed into the mixing chamber 134 of the cartridge. The packing density of the beverage ingredients in the mixing chamber 134 can be changed as desired.
Then, the laminated material 5 is attached to the external the th element 2 and the inner element 3 just as described above in previous versions.
When using water enters the mixing chamber 134 through four slits 36 similarly to the previous versions of the cartridge. Water is supplied radially downward through the mixing chamber and is mixed with the beverage ingredients contained in it. The product is dissolved or mixed in water to form a beverage in the mixing chamber 134 and is then routed through the holes 85 in the annular channel 86 due to the pressure of beverage and water in the mixing chamber 134. Offset arrangement on the periphery of the four inlet slots 36 and five holes 85 ensures that the water jet can not pass directly radially from the inlet slots 36 in the holes 85 without circulation inside the mixing chamber 134. Thus, the degree and consistency of dissolution or mixing of the product is greatly increased. The drink goes up in the annular channel 86 through the openings 89 between the brackets 87 into the chamber 90. Drink passes from the chamber 90 through the inlet openings 45 between the support walls 49 in the discharge spout 43 to the outlet 44 from which the beverage is poured into the receiver, such as a Cup. The cartridge can be used for beverage ingredients in the form of viscous liquids or gels. In one of the applications in the cartridge 1 contains liquid chocolate viscosity 1700-3900 MPa at ambient temperatures is whether 5000-10000 MPa at 0° dry balance BRICs 67+3. In another application in the cartridge 1 contains liquid coffee viscosity 70-2000 MPa at ambient temperature or 80-5000 MPa at 0° when the coffee has a total solids content of 40-70%.
The fourth variant of the cartridge 1 shown in Fig-34. This version of the cartridge 1 is used for delivery of liquid products, such as concentrated liquid milk. Many features of a fourth variant of the cartridge 1 are the same as in the previous embodiments, and similar signs used the same position. In the following description, discuss the differences between the fourth and previous versions. Common signs that have similar functions, detail will not be considered.
The external element 2 is the same as in the third embodiment of the cartridge 1, as shown in Fig-23.
The cylindrical funnel 40 of the inner element 3 similar to those shown for the second variant of the cartridge 1, but with some differences. As shown in Fig, the discharge spout is made with the upper section 106 in the form of a truncated cone and the lower cylindrical section 107. Three axial ribs 105 are provided on the inner surface of the discharge spout 43 to the direction of the received drink down to the outlet 44 and prevent turbulence of the drink inside the trunk. Therefore, the ribs 105 are used as the e of the guide screens. As in the second embodiment of the cartridge 1, the annular flange 47 has a hole 71 for receiving the air. However, the chute 75 under the hole 71 a more elongated than in the second option.
There skirt section 80, similar to that shown for the third variant of the cartridge 1 described above. In the rim 84 is provided from 5 to 12 holes 85.
Usually provided ten holes, and not five, as in the third embodiment, the cartridge 1.
Provided by the annular Cup 100 that extends from the flange 83 skirt section 80 and performed with him for one. Annular Cup 100 includes expanding the housing 101 with an open upper inlet 104 directed upwards. Four feed holes 103, shown in Fig and 31, are placed in the housing 101 at the lower end of the bowl 100 or near where it connects to the skirt section 80. Preferably, the feed holes ravnodusnost on the periphery of the bowl 100.
Laminated material 5 is a material of the same type as described above in previous versions.
The Assembly procedure of the fourth version of cartridge 1 is the same as for the third option.
The fourth version of the cartridge is similar to the third option. Water enters the cartridge 1 and the mixing chamber 134 in the same way as before. In the chamber the water is mixed with the liquid product and Rabb who made it, and then displaced down the bowl 100 and through the openings 85 to the outlet 44, as described above. Portion of the liquid product initially contained in the circular bowl 100, as shown in Fig, not subject to immediate dilution with water in the mixing chamber 134. Diluted liquid product in the lower portion of the mixing chamber 134 will tend to exit through the holes 85 and not to rise in the annular Cup 100 through the upper inlet opening 104. Therefore, a liquid product in an annular Cup 100 will remain relatively concentrated in the early stages of the business cycle compared with the product in the lower portion of the mixing chamber 134. A liquid product in an annular Cup 100 is dripping through the feed holes 103 under the influence of gravity in the product stream leaving the mixing chamber 134 through openings 85 and down the bowl 100. Ring bowl 100 is used to equalize the concentration of the diluted liquid product flowing in the cylindrical funnel 40, by holding part of the concentrated liquid product and releasing it in the thread facing the liquid continuously during the working cycle, as shown in figa, where the concentration of milk, measured as a percentage of total dry matter, shown during the working cycle duration of approximately 15 C. Line "a" shows the profile is concentratie in the presence of the bowl 100, while the line "b" shows the cartridge without the bowl 100. It is seen that the concentration profile in the presence of the bowl 100 is more uniform during the working cycle and there is an immediate sharp drop in concentration that occurs in the absence of the bowl 100. Initial concentration of milk is usually 30-35% of soluble substances and at the end of the cycle - 10% soluble substances. This leads to the fact that the dilution ratio is about 3 to 1, although in the present invention are possible factors of dilution from 1 : 1 to 6 : 1. For other liquid beverage ingredients concentration can vary. For example, for liquid chocolate initial concentration of approximately 67% of soluble substances, and at the end of the cycle - 12-15% of soluble substances. This leads to the dilution factor (the ratio of the water environment and ingredient of the beverage to be bottled drink) about 5 to 1, although in the present invention are possible factors of dilution from 2 to 1 to 10 to 1. For liquid coffee initial concentration is 40-67%, and the concentration at the end of the spill - 1-2%. As a result, the dilution ratio is from 20 : 1 to 70 : 1, although in the present invention are possible factors of dilution from 10 to 1 to 100 to 1.
From the annular channel 86 beverage under pressure supplied through the opening 128 due to the pressure of the drink is collected in the filtration Cam is re 134 and the chamber 90. The beverage thus fed through a hole 128 in the form of strong narrow jet and into the expansion chamber formed by the upper end of the discharge spout 43. As shown in Fig, a jet of the beverage passes directly over the hole 71 for air. Upon receipt of the drink in the discharge spout 43 the pressure of the jet of the beverage falls. As a result, the air is captured in the flow of the beverage in the form of small air bubbles in the flow of air through the opening 71. A jet of the beverage coming out of the holes 128, outlet down through the funnel to the outlet 44 from which the beverage is poured into the receiver, such as a Cup, in which air bubbles form the desired foam.
Preferably, the inner element 3, the outer member 2, the laminated material 5 and the filter 4 can easily be sterilized due to the fact that these parts are detachable and each individual item does not contain tortuous passages or narrow slits. The necessary passages are formed only after the joining of the parts after they have been sterilized. This is especially important when the ingredient of the drink is a product based on milk, such as liquid milk concentrate.
The fourth option of making a cartridge for a drink especially preferred for the issuance of the concentrated liquid product based on milk, such as liquid Molo is O. Earlier products from powdered milk was provided in the form of small packages to add in the prepared drink. However, for drink type cappuccino need to whisk the milk into foam. This was previously achieved by passing steam through the liquid dairy product. However, for this it is necessary to ensure the supply of steam, which increases the cost and complexity of the machine used for the issuance of a drink. The use of steam also increases the risk of injury during operation of the cartridge. Accordingly, the present invention provides a cartridge for a drink with a concentrated liquid product based on milk. Discovered that by concentrating milk product can be produced significantly more foam from a certain volume of milk compared with fresh or pasteurized milk. This reduces the size required for the print cartridge with milk. Fresh bold milk contains about 1.6% fat and 10% dry matter. The products of the concentrated liquid milk according to the invention contain from 0.1 to 12% fat and 25-40% dry matter. In a typical example, the product contains 4% fat and 30% dry matter. The products of the concentrated liquid milk suitable for foaming using a machine for the preparation of low pressure, as will be described below. In particular, the foaming of the milk produced in the runs at pressures below 2 bar, preferably about 1.5 bar, using a cartridge according to the fourth variant of the implementation described above.
The formation of foam from the concentrated milk is particularly preferable for drinks such as cappuccino and milk shakes. Preferably the passage of milk through the hole 128 and over the hole 71 for air, as well as the possible use of the bowl 100 allows you to reach the level of foaming milk above 40%, preferably above 70%. For liquid chocolate possible levels of spineuniverse above 70%. For liquid coffee possible levels of foaming above 70%. The level of expansion is measured as the ratio of the volume of the resulting foam to the volume of liquid ingredient granted drink. For example, if issued 138,3 ml of drink, of which 58,3 ml represent the foam, the foaming is[58,3/(138,3-58,3)]·100=72,9%. Foaming milk (and other liquid ingredients) increases with the presence of the bowl 100, as can be seen in fig.35b. Milk frothing issued in the presence of the bowl 100 (line "a"), higher than that of milk, given when no bowls (line "b"). This is because the milk frothing is directly dependent on the concentration of milk, and, as shown in figa, the Cup 100 supports a higher concentration of milk during the greater part of the working cycle. It is also known that wspania is their milk is directly dependent on the temperature of the water environment, as shown in figs. Thus, the Cup 100 is preferred because more milk left in the cartridge until almost the end of the working cycle, when the aqueous medium has the highest temperature. It also improves the foaming.
The cartridge according to the fourth variant implementation is also preferred for delivery of liquid coffee products.
