Description

  The present invention relates to a cartridge for preparing a beverage, and in particular, a seal formed of a material that is substantially impermeable to air and moisture and containing one or more ingredients for beverage preparation. Relates to a used cartridge.

It has heretofore been proposed to seal beverage preparation ingredients in individual packages that are impermeable to air. For example, cartridges and capsules that compress and store ground coffee are known for use in certain coffee brewing machines, commonly referred to as “espresso” machines. In the production of coffee using such a brewing machine, a coffee cartridge is placed in the brewing chamber, and hot water passes through the cartridge at a relatively high pressure to extract ground coffee components from the ground coffee. Produce coffee drinks. Usually such machines operate at pressures in excess of 6 × 10 5 Pa. This type of preparation machine has heretofore been relatively expensive because components such as the water pump and seals it must withstand high pressures.

Patent Document 1 describes a beverage preparation cartridge that generally operates at 0.7 to 2.0 × 10 5 Pa. However, this cartridge is designed for use in beverage brewers for commercial or industrial markets and is relatively expensive. Accordingly, there is a need for a beverage preparation cartridge that makes the cartridge and beverage preparation machine particularly suitable for the home market in terms of price, performance and reliability.

  It has also proved difficult to sterilize beverage cartridges of the type described above due to the narrow and serpentine passages formed in the cartridge body. For example, sterilization by exposing the cartridge to the above is not effective against the serpentine passage. This is because the surface tension characteristics of the cartridge prevent the vapor from entering the serpentine passage, and therefore the entire component surface cannot be exposed to the vapor.

  Beverage cartridges are prone to splatter and splash problems, and as the beverage is served from the cartridge, the beverage is sprayed or splashed out of the rim of the container. This occurs especially when the beverage is served at a relatively high pressure. Attempts have been made to alleviate this problem by providing the beverage preparation machine with a dispensing probe that guides the beverage into the container. However, the dispensing probe tends to become contaminated with beverage residues over time and is difficult to clean. In addition, there is a risk of cross-contamination between different beverages.

  In addition, in the cartridge of Patent Document 1, a beverage jet is formed by passing a beverage through an aperture. It has proven difficult to accurately dimension and position this type of aperture. It is very important to accurately dimension and position the aperture. This is because it is important that air bubbles are properly entrained in the final beverage. It is particularly difficult to form a small diameter aperture in an injection molded component when the aperture is placed inside and surrounded by other parts of the component. A conventional method of forming the aperture is to use mold pins that are sized to the required diameter of the aperture. However, the aperture formed by the mold pin is usually only towards the opening of the component (this opening allows the mold pin to access the component during molding). As a result, in the beverage cartridge, since the beverage is guided as it is toward the outlet, it is supplied from the opening at a very high speed of 12 to 16 m / s.

International Publication No. 01/58786

  One factor in cartridge reliability is its ability to withstand internal pressure. Accordingly, it is an object of the present invention to provide a beverage cartridge having an improved ability to withstand internal pressure.

  In order to make such a cartridge inexpensive, it is desired to manufacture the cartridge by a simple and reliable method. In particular, it is desirable to reduce the level of manual handling of cartridge components during manufacture and to reduce the total number of components.

  Accordingly, the present invention is a cartridge that contains one or more types of beverage ingredients and is formed of a material that is substantially impermeable to air and moisture, wherein the cartridge uses an aqueous medium as its cartridge. An inner portion comprising an inlet for introduction into the outlet and an outlet for discharging a beverage produced from the one or more types of beverage ingredients, wherein the cartridge is coupled and assembled to the outer member. And wherein the inner portion comprises a spout forming the outlet of the cartridge.

  The cartridge of the present invention is easily assembled with the main components being the inner and outer members. By using separate components as the inner member and the outer member and combining them together, the production of each component can be optimized. This is particularly advantageous in the cartridges of the present invention where very small tolerances are desired because the beverage flow path through the cartridge is formed by the interface between the outer member and the inner member. In addition, the inner and outer member components can be easily sterilized when in a separated state prior to assembly. When these components are combined, several serpentine serpentine paths are formed that cannot be effectively sterilized in a known manner. The ability to sterilize components is a particularly advantageous feature when the cartridge is used to supply a beverage based on milk. In addition, by using separate components to be joined, there is no need to invert the cartridge during assembly. This is because the bonding of the lid, such as the bonding of the inner member and the additional filter, the filling of the beverage ingredients and the lamination, can all be performed by one posture of the outer member.

  The advantage is that the inner member has a spout. The spout serves to guide the spilled beverage to a container such as a cup. The spout is useful for preventing extra splashing of the beverage and adjusting the flow characteristics to allow the beverage to move from the cartridge to the container. For example, by defining the shape of the spout so as to reduce the degree of turbulent flow applied to the beverage, it is possible to prevent the foam contained in the beverage from being reduced more than necessary. Also, the advantage is that the cartridge itself has a spout rather than providing a separate spout in the beverage preparation machine. Thus, there is no risk of cross-contamination between different beverages in the supply cycle. Each spout is used only once and is disposed of with the rest of the cartridge. It is also preferred that the beverage flowing out of the spout does not come into contact with the outlet mechanism of the beverage preparation machine. This prevents the beverage preparation machine from being soiled by beverage residues. Preferably, the spout is integral with the inner member. The advantage is that the spout and inner member are a single unit integrated by mold or other method, reducing the manufacturing cost of the cartridge and the number of components that need to be assembled. It is.

  In one embodiment, the spout includes a tapered portion. In other embodiments, the spout comprises a cylindrical portion. In a further optional variant, the spout comprises a partition that extends at least in part along its length. The partition reduces splashing of the spilled beverage.

  Preferably, a snap fit structure is provided for joining the outer member and the inner member. Typically, the snap-fit structure includes cooperating formations on the inner and outer members. The snap-fit structure not only provides for quick assembly of the inner and outer members, but is a way to ensure coupling. The advantage is that no adhesive is required inside the cartridge that will be exposed to the beverage ingredients.

  Preferably, the outer member comprises a closed first end and an open second end, with the spout outlet facing the open second end in the inner member coupled to the outer member. Also preferably, the inlet is directed to the open second end of the outer member. The inlet and outlet are thus facing the same side of the cartridge. This allows the cartridge to be used in a low-profile machine, and in use allows the perforation means to form the inlet and outlet to protrude from a single surface of the beverage conditioning machine.

  Preferably, the outer member and the inner member are joined at or near the closed first end portion of the outer member. Therefore, the inner member and the outer member are joined at a position away from the open end of the outer member, that is, the mouth. The advantage is that the coupling step can be performed prior to filling the cartridge with beverage ingredients and prior to sealing the open end or mouth of the cartridge. This allows the inner and outer members to be joined first to form a subassembly and then transferred to the filling station of the packing line to contain one or more beverage ingredients, thus simplifying the assembly process. Become. Next, the filled cartridge is sealed. This is done, for example, by heat welding the laminate sheet to the open end of the outer member. This assembly process eliminates the difficult task of aligning and maintaining the alignment of the outer member, inner member and laminate through the thermal welding step.

  Preferably, the outer member has an inwardly extending portion and is received at the proximal end of the spout when the outer member and the inner member are joined.

  In one embodiment, the inner member comprises a frame on which a filter is provided. Preferably, one or more passages are formed between the closed first end of the outer member and the frame when the inner member and the outer member are joined. Further, the one or more passages are defined by a web extending upward from the frame to the closed first end of the outer member. Preferably, the one or more passages are inclined downwardly toward the spout.

  In other embodiments, the inner member comprises a skirt surrounding the spout. Preferably, the skirt has an upper extension to contact the closed first end of the cartridge when the cartridge is assembled. Preferably, the upper rim of the upper extension engages with a cooperating formation on the outer member to provide a snap-fit structure for coupling the inner member to the outer member. Typically, the outer member cooperating formation is an inward extension.

  Preferably, the cartridge is disk shaped. The cartridge may further comprise means for generating a beverage jet, the means having an aperture in the beverage flow path between the inlet and the outlet. Preferably the inlet and / or outlet is covered with a substantially air and water impermeable material prior to forming the cartridge inlet and / or outlet for use. For example, the inlet and / or outlet are covered with a substantially air and water impermeable laminate. The laminate may be polypropylene. The outer member and / or the inner member can be made of polypropylene, for example. Alternatively, the outer member and / or the inner member can be formed of a biodegradable polymer.

  Preferably, the inner member forms a load-bearing member.

  Preferably, a plurality of cartridges as described above are provided so that the percentage yield of the beverage produced from one or more beverage ingredients stored in the cartridge is within a standard deviation of 1.0.

  In addition, the present invention is a cartridge that contains one or more types of beverage ingredients and is formed of a material that is substantially impermeable to air and moisture, and the cartridge uses an aqueous medium as the cartridge. An inlet for introduction into the outlet, and an outlet for discharging a beverage produced from the one or more types of beverage ingredients, wherein the cartridge is inserted into the outer member, and an inner portion inserted into the outer member; Means for generating a jet of the beverage, the jet generating means having an aperture in the beverage channel for connecting the inlet to the outlet, the aperture being the inner member and the outer A cartridge characterized by being defined by an interface between members.

  The cartridge of the present invention produces a beverage jet that can change the look and characteristics of the beverage provided. For example, a large number of small bubbles can be generated in the provided beverage by mixing air into the beverage jet. The cartridge of the present invention is easily assembled with the main components being the inner and outer members. By using separate components as the inner member and the outer member and combining them together, the manufacture of each component and the assembly of the cartridge can be optimized. This is particularly advantageous in the cartridges of the present invention where very small tolerances are desired for the size and placement of the apertures that generate the jets and for the rest of the beverage flow path through the cartridge. In addition, by setting the aperture in a direction perpendicular to the overall direction of the flow path, the beverage can collide with the wall surface of the cartridge and be decelerated prior to supply. As mentioned above, it is difficult for injection molded components to refine and orient the aperture. According to the present invention, such difficulty is achieved by defining the aperture using the interface between the inner member and the outer member, rather than forming the entire aperture in a single component, for example by mold pins. Is resolved.

  One of the inner member or the outer member has an opening, and the other of the inner member or the outer member has an obstruction, and when the inner member is inserted into the outer member, the obstruction partially occludes the opening. An aperture is defined.

The advantage is that it is easier to create separate openings and occlusions that are combined to define the aperture. Preferably, the opening comprises an elongated slot, which can be provided in the inner member. In this case, the outer member has a blocking portion. Preferably, the closing portion includes an extending portion of the outer member, and at least a part thereof protrudes into the inner member. An elongated slot can be formed in the cylindrical wall of the inner member. Preferably, the elongated slot extends to the upper edge of the cylindrical wall. In one embodiment, the extension of the outer member is a cylindrical extension and is received in a sliding fit within the cylindrical wall of the inner member. Typically, the aperture has a cross-sectional area of 0.4-0.7 mm 2.

  Preferably, the cartridge further comprises at least one air inlet and means for creating a pressure drop in the beverage jet, wherein in use, the plurality of small bubbles from the at least one air inlet into the beverage. To be introduced. Preferably, at least one air inlet is provided in the inner member downstream from the aperture. The inner member may comprise a spout that forms an outlet. Preferably, the beverage jet provided by the aperture is directed to the spout so that it can impinge on the surface of the spout while being introduced from the aperture and exiting the outlet. Preferably, the surface is a concave wall of the spout. The concave wall is preferably arranged at the part of the spout opposite to the aperture. Preferably, the aperture guides the beverage to flow at an angle substantially perpendicular to the beverage flow exiting the outlet. Thus, the beverage is deflected before it can leave the cartridge, so that the beverage slows down. This is desirable for preventing scattering of the container.

  The components of the inner member and outer member can be more easily sterilized when in a separated state prior to assembly. When these components are combined, several serpentine serpentine paths are formed that cannot be effectively sterilized in a known manner. The ability to sterilize components is a particularly advantageous feature when the cartridge is used to supply a beverage based on milk.

  The advantage is that the spout is integrated into the inner member. The spout serves to guide the spilled beverage to a container such as a cup. The spout is useful for preventing extra splashing of the beverage and adjusting the flow characteristics to allow the beverage to move from the cartridge to the container. For example, by defining the shape of the spout so as to reduce the degree of turbulent flow applied to the beverage, it is possible to prevent the foam contained in the beverage from being reduced more than necessary. Also, the advantage is that the cartridge itself has a spout rather than providing a separate spout in the beverage preparation machine. Thus, there is no risk of cross-contamination between different beverages in the supply cycle. Each spout is used only once and is disposed of with the rest of the cartridge. It is also preferred that the beverage flowing out of the spout does not come into contact with the outlet mechanism of the beverage preparation machine. This prevents the beverage preparation machine from being soiled by beverage residues. The advantage is that the spout and inner member are a single unit integrated by mold or other method, reducing the manufacturing cost of the cartridge and the number of components that need to be assembled. It is.

  Preferably, the cartridge is disk shaped. The outer member and / or the inner member can be made of polypropylene, for example. It is also possible to form the cartridge with a biodegradable polymer.

  In addition, the present invention is a cartridge that contains one or more types of beverage ingredients and is formed of a material that is substantially impermeable to air and moisture. A compartment for containing a plurality of types of beverage ingredients, the compartment for introducing a water medium therein, a plurality of inlet apertures, and a beverage produced from the one or more types of beverage ingredients And a part of the aqueous medium entering the compartment through the inlet aperture is forcibly circulated in the compartment by shifting the part of the inlet aperture and the outlet aperture. And then exiting the compartment through the outlet aperture, the plurality of inlet apertures being disposed around the compartment. To provide a cartridge.

  An advantage is that the cartridge of the present invention comprises an inlet aperture and an outlet aperture that is at least partially offset. Thereby, it is possible to prevent the aqueous medium entering the compartment storing the beverage ingredients from passing from the entrance aperture to the exit aperture as it is. Rather than passing through, the aqueous medium is forced to circulate within the compartment before leaving the outlet aperture. Thereby, since almost all of the beverage ingredients in the compartment are in contact with the aqueous medium flow path, the degree of mixing of the aqueous medium and the beverage ingredients is increased.

  Preferably, the inlet apertures can be arranged at equal intervals around the compartment. Preferably, with respect to the entrance aperture, the exit aperture is arranged towards the center of the compartment. The exit apertures can be equally spaced around the center of the compartment. By equally spaced the inlet and outlet apertures, a more uniform flow within the compartment is provided, thereby providing a more reliable mixing of the beverage ingredients and the aqueous medium.

  Preferably, the cartridge comprises 3-10 inlet apertures. In one embodiment, four inlet apertures are provided.

  Preferably, the cartridge comprises 3 to 10 exit apertures. In one embodiment, five exit apertures are provided.

  Preferably, the number of entrance apertures is not equal to the number of exit apertures.

  Preferably, the number of entrance apertures and the number of exit apertures are given by the following formula:

Xo = Xi + C
Where Xi = number of entrance apertures
Xo = number of exit apertures
C = 0 or set of integers not including nXi
n = any integer The advantage is that the number of inlet and outlet apertures is selected according to the above formula. This is particularly advantageous when the cartridge is disk-shaped and the apertures are equally spaced around the disk. This is because it is not necessary to pay attention to the alignment of the components of the cartridge including the inlet and outlet apertures during assembly. Whatever the component orientation, at least some of the entrance and exit apertures will be misaligned. For example, if there are 4 inlet apertures and 5 outlet apertures, all spaced equally, no matter how the cartridge components including the inlet and outlet apertures are aligned, two or more inlets It is impossible to align the aperture with the exit aperture. As a result, the assembly procedure can be performed more quickly and easily. Alternatively, the cartridge may include an equal number of inlet apertures and outlet apertures, but spaced apart to ensure that at least some of the inlet and outlet apertures are offset.

  Typically, the inlet aperture is provided in the outer member of the cartridge and the outlet aperture is provided in the inner member of the cartridge. Preferably, the inner member comprises a spout that communicates with the outlet aperture.

  In the preferred embodiment, the cartridge is disk-shaped. Preferably, the aqueous medium flowing into the compartment through the inlet aperture is directed radially inward toward the center of the cartridge.

  As a special application example of the cartridge, it can be seen that it is used for a liquid material in the form of a viscous liquid, ie, a gel. In one application, a liquid chocolate ingredient is housed in the cartridge 1, which has a viscosity of 1700-3900 mPa at ambient temperature, 5000-10000 mPa at 0 ° C., and 67 solids refractive solids. The degree is ± 3. In another application, the cartridge 1 contains liquid coffee, which has a viscosity of 70-2000 mPa at ambient temperature, 80-5000 mPa at 0 ° C., and a total solid content of 40-70%. .

  When using soluble beverage ingredients such as viscous liquids or gels, it is particularly problematic that the ingredients do not mix thoroughly with the aqueous medium. In particular, in a cartridge containing such a product, a channel connecting the inlet and the outlet of the cartridge may be quickly generated due to local dissolution of the raw material. Then, the channel forms a flow path having a relatively low resistance with respect to the remaining aqueous medium, and does not pass through the remaining undissolved high viscosity raw material in the compartment, but easily flows along the channel. The cartridge of the present invention mainly solves this problem, and not only dissolves most of the raw materials by forcibly recirculating the aqueous medium in the compartment, but also creates turbulence in the compartment. It acts to promote the mixing of the remaining raw materials and prevents the generation and maintenance of a low-resistance flow path connecting the inlet aperture and the outlet aperture.

  The outer member and / or inner member can be made of polypropylene and can be injection molded. In one embodiment, the outer member and / or inner member is formed of a biodegradable polymer.

  The present invention is a cartridge that contains one or more types of beverage ingredients and is formed of a material that is substantially impermeable to air and moisture, the cartridge being said one type or a plurality of types. An outer member defining a storage chamber for storing the beverage ingredients, and an inner member having a spout that forms an outlet for spilling beverages generated from the one or more kinds of beverage ingredients, The cartridge is characterized in that the inner member forms a load receiving member.

  The cartridge of the present invention comprises a robust mechanism for dispensing beverages. In particular, the inner member serves as a load receiving member and can withstand a relatively high compressive load during use. This allows the cartridge to be used in a beverage preparation machine that applies a compressive load to the cartridge prior to beginning the dispensing cycle. This reduces the risk of damage to the cartridge when the interior is pressurized. In addition, the action of the compression load on the cartridge ensures that the cartridge components are held in place.

  Preferably, the inner member and the outer member are separate components that are combined when the cartridge is assembled.

  Preferably, the cartridge further comprises a filter coupled to the inner member.

  In one embodiment, the inner member is formed of polypropylene. In other forms, the outer member and / or the inner member are formed of a biodegradable polymer.

  The advantage is that the inner member has a spout. The spout serves to guide the spilled beverage to a container such as a cup. The spout is useful for preventing extra splashing of the beverage and adjusting the flow characteristics to allow the beverage to move from the cartridge to the container. For example, by defining the shape of the spout so as to reduce the degree of turbulent flow applied to the beverage, it is possible to prevent the foam contained in the beverage from being reduced more than necessary.

  Preferably, the inner member and the spout are formed as an integral member (piece).

  The present invention is also a cartridge that contains one or more beverage ingredients and is formed of a material that is substantially impermeable to air and moisture, the cartridge being closed first.

  Preferably, the load receiving member is disposed at or near the center of the cartridge.

  Preferably, the inner member is sufficiently rigid so that the cartridge can withstand compressive loads in excess of 130N. More preferably, the load receiving member is sufficiently rigid so that the cartridge can withstand a compressive load in excess of 200N. Preferably, the load receiving member has sufficient rigidity so that the load receiving member itself can withstand a compressive load exceeding 130N.

An outer member defining a storage chamber for storing the beverage ingredients, an inner member having a spout for forming an outlet for the beverage generated from the one or more types of beverage ingredients, and the storage chamber And a filter disposed between the spouts, wherein the inner member and the filter are coupled to the outer member in one operation by at least one weld. To do.

  The advantage is that the cartridge of the present invention is assembled in a reliable manner with minimal manual manipulation of the components. In addition, since the outer member, the inner member, and the filter can be assembled as a partial assembly first, it can be easily transported without causing the filter to drop off. As a result, the outer member, the inner member, and the filter can be assembled at a remote location, and the cartridge can be filled and sealed.

  Preferably, the outer member has an opening for accessing the storage chamber, and the inner member and the filter are coupled to the outer member at a base portion remote from the opening.

  Preferably, the inner member, the outer member and the filter are annular.

  Preferably, the weld is substantially circular.

  In one embodiment, the inner member and the outer member are plastic materials, and the at least one weld is formed by ultrasonic welding.

  In one example, the inner member comprises a frame and the at least one weld is formed around the frame. The welded portion prevents the beverage from flowing out of a portion of the storage chamber other than the filter. Preferably, the frame includes a plurality of webs extending upwardly from the frame toward the closed first end of the outer member, and defines one or more passages between the frame and the closed first end of the outer member.

  As used herein, the term “cartridge” is intended to include any package, container, sachet, or container that contains one or more beverage ingredients in the manner described. The cartridge may be rigid, semi-rigid, or flexible.

  The cartridge of the present invention contains one or more kinds of beverage ingredients suitable for refining beverage products. Examples of the beverage include beverages made from milk containing coffee, tea, chocolate or milk. The beverage ingredients can be powdered, ground, leaf-based, or liquid. The beverage ingredients may be insoluble or soluble. Examples include roasted and ground coffee, leaf tea, powdered chocolate and soups, liquid milk-based beverages and concentrated fruit juices.

  The present invention also provides a cartridge that contains one or more types of beverage ingredients and is formed of a material that is substantially impermeable to air and moisture, the cartridge containing an aqueous medium in the cartridge. And an outlet for allowing the beverage produced from the one or more types of beverage ingredients to flow out, and the cartridge is coupled to the outer member and assembled to the outer member. An inner portion that forms the outlet of the cartridge, and a snap-fitting structure is provided for coupling the outer portion and the inner portion during assembly of the cartridge. A cartridge is provided.

  The cartridge of the present invention is easily assembled with the main components being the inner and outer members. By using separate components as the inner member and the outer member, and combining them by a snap-fitting structure, the manufacture of each component and the assembly of the cartridge can be optimized. This is particularly advantageous in the cartridges of the present invention where very small tolerances are desired because the beverage flow path through the cartridge is formed by the interface between the outer member and the inner member. In addition, the components of the inner and outer members can be easily sterilized when in a separated state prior to assembly. When these components are snapped together, a number of serpentine serpentine paths are formed that cannot be effectively sterilized in a known manner. The ability to sterilize components is a particularly advantageous feature when the cartridge is used to supply a beverage based on milk. A snap-fit structure not only provides for quick assembly, but is a way to ensure coupling. The advantage is that no adhesive is required inside the cartridge that will be exposed to the beverage ingredients.

  Typically, the snap-fit structure includes cooperating formations on the inner and outer members. Preferably, the outer member has a closed first end and an open second end, and the outlet of the inner member snap-fit with the outer member is directed to the open second end. Also preferably, the inlet is directed to the open second end of the outer member. The inlet and outlet are thus facing the same side of the cartridge.

  Preferably, the outer member and the inner member are snap-fitted at or near the closed first end portion of the outer member. Therefore, the inner member and the outer member are joined at a position away from the open end of the outer member, that is, the mouth. The advantage is that a snap-fit step can be performed prior to filling the beverage ingredients into the cartridge and prior to sealing the open end or mouth of the cartridge. This allows the inner and outer members to first snap fit to form a cartridge sub-assembly, which can then be transferred to the filling station of the packing line to contain one or more beverage ingredients so that the assembly process It will be easy. Next, the filled cartridge is sealed. This is done, for example, by thermally welding a laminate sheet to the open end of the outer member. This assembly process eliminates the difficult task of aligning and maintaining the alignment of the outer member, inner member and laminate through the thermal welding step.

  An advantage is that a water tight seal is formed by a snap fit of the inner and outer members.

  In one embodiment, the inner member further comprises a skirt surrounding the outlet. The skirt has an upper extension that has an upper rim that engages the cooperating formation of the outer member when the cartridge is assembled to couple the inner member to the outer member Snap fitting structure to make it. Typically, the outer member cooperating formation is an inward extension.

  Preferably, the outer member has an inward extension and is received at the proximal end of the spout when the outer member and inner member are joined.

  The advantage is that the inner member has a spout. The spout serves to guide the spilled beverage to a container such as a cup. The spout is useful for preventing extra splashing of the beverage and adjusting the flow characteristics to allow the beverage to move from the cartridge to the container. For example, by defining the shape of the spout so as to reduce the degree of turbulent flow applied to the beverage, it is possible to prevent the foam contained in the beverage from being reduced more than necessary. Also, the advantage is that the cartridge itself has a spout rather than providing a separate spout in the beverage preparation machine. Thus, there is no risk of cross-contamination between different beverages in the supply cycle. Each spout is used only once and is disposed of with the rest of the cartridge. It is also preferred that the beverage flowing out of the spout does not come into contact with the outlet mechanism of the beverage preparation machine. This prevents the beverage preparation machine from being soiled. Preferably, the spout is integral with the inner member. The advantage is that the spout and inner member are a single unit integrated by mold or other method, reducing the manufacturing cost of the cartridge and the number of components that need to be assembled. It is.

  In one embodiment, the spout includes a tapered portion. In other embodiments, the spout comprises a cylindrical portion. In a further optional variant, the spout comprises a partition that extends at least in part along its length. The partition reduces splashing of the spilled beverage.

  Preferably, the cartridge is disk shaped. The cartridge may further comprise means for generating a beverage jet, the means having an aperture in the beverage flow path between the inlet and the outlet. The outer member and / or the inner member can be made of polypropylene, for example.

  Embodiments of the present invention will be described with reference to the accompanying drawings. However, this is an example.

  As shown in FIG. 11, the cartridge 1 of the present invention mainly includes an outer member 2, an inner member 3, and a laminate 5. Combining the outer member 2, the inner member 3 and the laminate 5 connects the interior 120 for storing one or more kinds of beverage ingredients, the inlet 121, the outlet 122, and the inlet 121 to the outlet 122. Thus, the cartridge 1 having the beverage flow path penetrating the interior 120 is formed. The inlet 121 and the outlet 122 are initially sealed with the laminate 5, but are opened by drilling or cutting the laminate 5 in use. The beverage flow path is defined by the spatial interrelationship between the outer member 2, the inner member 3 and the laminate 5 as will be described below. In addition, components such as a filter 4 can optionally be included in the cartridge 1 as further described below.

  Next, a first type of cartridge 1 described as background knowledge is shown in FIGS. The first type of cartridge 1 is specifically designed for use in supplying filtered products such as roasted and ground coffee and leaf tea. However, this type of cartridge 1 and the other types described below are cocoa, coffee, tea, sweeteners, tonics, seasonings, alcoholic beverages, seasoned milk, fruit juices, squash, sauces And other products such as desserts can also be used.

  As can be seen from FIG. 5, the overall shape of the cartridge 1 is a substantially circular or disk shape whose diameter is significantly larger than the height. The major axis X passes through the center of the outer member as shown in FIG. Usually, the entire diameter of the outer member 2 is 74.5 mm ± 6 mm and the entire height is 16 mm ± 3 mm. Usually, the volume of the cartridge 1 is 30.2 ml ± 20%.

  The outer member 2 mainly includes a ball-shaped shell 10 having a curved annular wall 13, a closed top 11 and an open bottom 12. Since the annular wall 13 extends from the closed top portion 11 to the open bottom portion 12, the diameter of the outer member 2 is smaller at the top portion 11 than the diameter of the bottom portion 12. The annular wall 13 and the closed bottom 11 together define a container having an interior 34.

  A hollow, inwardly extending columnar extension 18 is provided on the top 11 closed about the major axis X. As can be seen better in FIG. 2, the cylindrical extension 18 includes a stepped profile having first, second and third portions 19, 20 and 21. The first portion 19 has a right cylindrical shape. The second portion 20 has a truncated conical shape and tapers inwardly. The third portion 21 is another right circular cylinder and is closed by the lower surface 31. The diameters of the first, second and third portions 19, 20 and 21 are such that the diameter of the cylindrical extension 18 narrows from the top 11 of the cylindrical extension 18 to the closed lower surface 31. It is getting smaller. A substantially horizontal shoulder 32 is formed in the cylindrical extension 18 at the joint between the second portion 20 and the third portion 21.

  An outwardly extending shoulder 33 is formed on the outer member 2 toward the bottom 12. This outwardly extending shoulder 33 forms a secondary wall 15 that is coaxial with the annular wall 13, thereby forming a manifold 16 between the secondary wall 15 and the annular wall 13. It has come to define. The manifold 16 passes around the periphery of the outer member 2. A series of slots 17 are provided in the annular wall 13 at the same height as the manifold 16, whereby the manifold 16 and the interior 34 of the outer member 2 are in gas and liquid communication. As shown in FIG. 3, the slot 17 includes a vertical slit formed in the annular wall 13. 20 to 40 slits are provided. In the illustrated embodiment, 37 slots 17 are provided around the manifold 16 at approximately equal intervals. The slot 17 is preferably 1.4 to 1.8 mm long. Usually, the length of each slot is 1.6 mm which is 10% of the entire height of the outer member 2. The width of each slot is 0.25 to 0.35 mm. Usually, the width of each slot is 0.3 mm. The width of the slot 17 is sufficiently narrow so that beverage ingredients do not pass through the manifold 16 either during storage or use.

  An inlet chamber 26 is formed in the outer member 2 around the outer member 2. As best seen in FIG. 5, a cylindrical wall 27 is provided which defines an inlet chamber 26 in the interior 34 of the outer member 2 and at the same time partitions the inlet chamber 26 from the interior 34 of the outer member 2. Yes. The columnar wall 27 has a closed upper surface 28 formed on one plane perpendicular to the long axis X, and an open lower end 29 on the same plane as the bottom 12 of the outer member 2. The inlet chamber 26 communicates with the manifold 16 through two slots 30 as shown in FIG. Alternatively, 1 to 4 slots may be used to communicate between the manifold 16 and the inlet chamber 26.

  A flange 35 that extends outward perpendicular to the long axis X is provided at the lower end of the shoulder 33 that extends outward. Usually, the width of the flange 35 is 2 to 4 mm. A portion of the flange 35 is expanded to form the handle 24 by holding the outer member 2. The handle 24 is provided with a rim 25 with the tip facing upward for easy gripping.

  The outer member 2 is formed as a single piece from high-density polyethylene, polypropylene, polystyrene, polyester, or a laminate of two or more thereof. Suitable polypropylene is a series of polymers available from DSM UK Limited (Redditch, UK). This outer member may be opaque, transparent or translucent. This manufacturing process can be injection molding.

  As shown in FIGS. 7 to 10, the inner member 3 includes an annular frame 41 and a cylindrical funnel 40 extending downward. As shown in FIG. 7, the long axis X passes through the center of the inner member 3.

  As best seen in FIG. 8, the annular frame 41 includes an outer rim 51 and an inner hub 52 joined by ten radial spokes 53 provided at equal intervals. The inner hub 52 is integral with the cylindrical funnel 40 and extends from the cylindrical funnel 40. A filtration aperture 55 is formed in the annular frame 41 between the radial spokes 53. The filter 4 is disposed on the annular frame 41 so as to cover the filtration aperture 55. The filter is preferably made of a material with high wet strength, such as polyester, a nonwoven fiber material. Other materials that can be used include moisture-impermeable cellulose materials such as cellulose materials containing woven paper fibers. The woven paper fibers can be mixed with polypropylene, polyvinyl chloride and / or polyethylene fibers. When such a plastic material is combined in a cellulose material, the cellulose material can be heat sealed. The filter 4 may be treated or coated with a heat and / or pressure activated material so that it can be sealed to the annular frame 41 by heat and / or pressure.

  As shown in the cross-sectional profile of FIG. 7, the inner hub 52 is disposed at a position below the outer rim 51, so that the profile of the annular frame 41 is inclined downward.

  An upright web 54 is provided on the upper surface of each spoke 53. This web divides the gap above the annular frame 41 into a plurality of passages 57. Each passage 57 is in a state in which the boundary is in contact with both sides divided by the web 54 and the lower surface of the filter 4. A passage 57 extends downwardly from the outer rim 51 toward the cylindrical funnel 40 and opens into the cylindrical funnel 40 at an opening 56 defined by the inner end of the web 54.

  The cylindrical funnel 40 includes an outer tube 42 that surrounds an inner spout 43. This outer tube 42 forms the outer surface of the cylindrical funnel 40. The spout 43 is joined to the outer tube 42 at its upper end by an annular flange 47. The spout 43 is located at the upper end thereof and communicates with the opening 56 of the passage 57, and at the lower end thereof, the outlet 44 through which the prepared beverage is passed and poured into a cup or other container. Including. The spout 43 includes a generally frustoconical portion 48 at its upper end and a cylindrical portion 58 at its lower end. The cylindrical portion 58 may be provided with a slightly inclined portion so that the width decreases toward the outlet 44. By providing the substantially truncated conical portion 48, the beverage can easily flow downward from the passage 57 toward the outlet 44 without causing turbulence in the beverage. A support web 49 is provided on the upper surface of the substantially frustoconical portion 48 at equal intervals around the cylindrical funnel 40. A plurality of channels 50 are defined between the support webs 49. The upper edges of the support webs 49 are at the same height and are perpendicular to the long axis X.

  As described above, the inner member 3 can be formed as a single piece by injection molding from polypropylene or a material similar to the same as the outer member 2.

  Alternatively, the inner member 3 and / or the outer member 2 may be made of a biodegradable polymer. Examples of suitable materials include degradable polyethylene (e.g., Symphony Environmental, SPITEK from Borehamwood, UK), biodegradable polyesteramide (e.g., Symphony Environmental, BAK1095), polylactic acid (PLG from Cargil, Minnesota, USA), starch series Examples include polymers, cellulose derivatives, and polypeptides.

  The laminate 5 is formed from two layers, a first layer made of aluminum and a second layer made of unstretched polypropylene. This aluminum layer is 0.02 to 0.07 mm thick. The unstretched polypropylene layer is 0.025 to 0.065 mm thick. In one embodiment, the aluminum layer is 0.06 mm thick and the polypropylene layer is 0.025 mm thick. This laminate is particularly advantageous because it has a high resistance to entrainment during assembly. For this reason, the laminate 5 can be cut into a correct size and shape in advance without causing distortion, and then transferred to the assembly station of the production line. This laminate 5 is therefore particularly suitable for welding. Other laminate materials can also be used, examples being PET / aluminum / PP, PE / EVOH / PP, PET / metallization / PP, and aluminum / PP laminates. You may use the stock by roll lamination instead of the punched stock.

  The cartridge 1 may be closed with a rigid or semi-rigid lid instead of a flexible laminate.

Assembling the cartridge 1
a) inserting the inner member 3 into the outer member 2;
b) cutting the filter 4 into a fixed shape, placing it on the inner member 3 and receiving it on the cylindrical funnel 40 so as to be in a position facing the annular frame 41;
c) joining the inner member 3, the outer member 2 and the filter 4 by ultrasonic welding;
d) filling the cartridge 1 with one or more types of beverage ingredients;
e) attaching the laminate 5 to the outer member 2.

  The above steps are described in further detail below.

  The outer member 2 is oriented with its open bottom 12 facing up. Next, the inner member 3 is inserted into the outer member 2 so that the outer rim 51 can be received loosely in the axial extension 14 at the top 11 of the cartridge 1. At the same time, the cylindrical extension 18 of the outer member 2 is received in the upper part of the cylindrical funnel 40 of the inner member 3. The third portion 21 of the cylindrical extension 18 is accommodated in the cylindrical funnel 40 in a state where the closed lower surface 31 of the cylindrical extension 18 is in contact with the support web 49 of the inner member 3. Next, the filter 4 is placed on the inner member 3 such that the filter material contacts the annular rim 51. The filter 4 is joined to the inner member 3 by an ultrasonic welding process, and at the same time, the inner member 3 is joined to the outer member 2 in the same processing step. The inner member 3 and the filter 4 are welded along the outer rim 51. The inner member 3 and the outer member 2 are joined by a weld line along the upper edge of the outer rim 51 and the web 54.

  As best seen in FIG. 11, when the outer member 2 and the inner member 3 are joined together, a hole space 130 in the interior 120 is created below the annular flange 41 and outside the cylindrical funnel 40, which becomes the filtration chamber. . The filter paper 4 separates the filtration chamber 130 and the passage 57 above the annular frame 41.

  One or more types of beverage ingredients 200 are stored in the filtration chamber 130. One or more types of beverage ingredients are packaged in the filtration chamber 130. In the case of a filtered beverage, this ingredient is usually roasted and ground coffee or leaf tea. The packaging density of the beverage ingredients in the filtration chamber 130 can be changed as desired. Typically, for filtered coffee products, this filtration chamber contains 5.0 to 10.2 grams of roast and ground coffee in a filter bed, typically 5 to 14 mm thick. In addition, one or more kinds of objects such as spheres are placed in the interior 120 so that they can move freely in the interior 120, causing turbulence when the beverage is poured, and crushing the precipitate of the beverage ingredients. To facilitate mixing.

  Next, the laminate 5 is attached to the outer member 2 by forming a welded portion 126 around the laminate 5 in order to join the laminate 5 to the lower surface of the flange 35 extending outward. The weld 126 extends to seal the laminate 5 against the lower edge of the cylindrical wall 27 of the inlet chamber 26. Further, the welded portion 125 is formed between the laminate 5 and the lower edge portion of the outer tube 42 of the cylindrical funnel 40 so that the inner member 3 is bridged between the outer member 2 and the laminate 5. This laminate 5 becomes the lower wall of the filtration chamber 130 and seals the inlet chamber 26 and the cylindrical funnel 40. However, a small gap 123 is formed between the laminate 5 and the lower edge of the spout 43 before supply. Depending on the material properties of the laminate 5, various welding methods such as heat and ultrasonic welding can be used.

  Advantageously, there is an inner member 3 between the outer member 2 and the laminate 5. The inner member 3 is formed of a relatively hard material such as polypropylene. As a result, the inner member 3 becomes a load-bearing member that acts to maintain the space between the laminate 5 and the outer member 2 even when the cartridge 1 is compressed. In use, it is preferable that the compression load received by the cartridge 1 is 130 to 280N. The compressive load acts on the beverage preparation machine where the cartridge is inserted. However, depending on the cartridge and machine arrangement, the lower limit of the force can exceed 50N. The compressive force acts to prevent the cartridge from being damaged under internal pressure, and at the same time plays the role of bringing the inner member 3 and the outer member 2 together. This ensures that the inner dimensions of the passage and aperture in the cartridge 1 are fixed and do not change even when the cartridge 1 is pressurized.

  In order to use the cartridge 1, first, it is inserted into the beverage preparation machine, and the inlet 121 and the outlet 122 are opened by the piercing member of the beverage preparation machine. The perforating member perforates the laminate 5 and turns it back. A pressurized aqueous medium (usually water) is placed in the cartridge 1 at a pressure of 0.1 to 2.0 bar and passed from the inlet 121 into the inlet chamber 26. From here, the water passes through the slot 30 and around the manifold 16 and enters the filtration chamber 130 of the cartridge 1 through the plurality of slots 17. The water is pushed inward in the radial direction through the filtration chamber 130 and is mixed with the beverage ingredients 200 stored therein. This water is simultaneously pushed up through the beverage ingredient. The beverage formed by the water passing through the beverage ingredient in this way passes through the filter 4 and the filtration aperture 55 and enters the passage 57 located above the annular frame 41. Since the filter 4 is sealed to the spokes 53 and the rim 51 is welded to the outer member 2 and there is no other outlet, all of this beverage will surely pass through the filter 4.

  The beverage then flows downward along a radial passage 57 formed between the webs 54 and passes through the opening 56 into the cylindrical funnel 40. Subsequently, it passes between the support webs 47 along the channel 50 and falls from the spout 43 to the lower outlet 44, whereby the beverage is poured into a container such as a cup.

  Preferably, the beverage preparation machine includes an air purge capability so that the compressed beverage is forced into the cartridge 1 at the end of the operating cycle so that the residual beverage flows out into the container.

  12 to 18 show a second type of cartridge 1. The second type of cartridge 1 is used to formulate espresso type products such as roasted and ground coffee when it is desired to produce a beverage with fine bubble foam known as crema. Is specifically designed to do. Since many of the features of the second type cartridge 1 are the same as those of the first type, like reference numerals are used for like features. In the following description, the difference between the first model and the second model will be described. Detailed descriptions of common features that function in the same manner will be omitted below.

  The structure of the outer member 2 is provided in the first type cartridge 1 and is the same as that shown in FIGS.

  The annular frame 41 of the inner member 3 is the same as that of the first type. In addition, the filter 4 is disposed on the annular frame 41 so as to cover the filtration aperture 55. The outer tube 42 of the cylindrical funnel 40 is the same as in the first case. However, the inner member 2 of the second type has some differences compared to the case of the first type. As shown in FIG. 16, the spout 43 is provided with a partition 65 that partially extends from the outlet 44 toward the spout 43. By providing this partition 65, it becomes easy to prevent the beverage from splashing and / or splashing when leaving the spout 43. The profile of the spout 43 is also different, and this spout 43 includes a stepped profile with a clear bend 66 near the upper end of the tube 43.

  A rim 67 is provided upright from the annular flange 47 to connect the outer tube 42 and the spout 43. The rim 67 surrounds the inlet 45 to the spout 43 and defines an annular channel 69 between the rim 67 and the upper portion of the outer tube 42. The rim 67 is provided with an inward shoulder 68. At one location around the rim 67, an aperture 70 is provided in the form of a slot, which is slightly more than the height of the shoulder 68 from the upper edge of the rim 67, as best seen in FIGS. It extends to the lower part. The width of this slot is 0.64 mm.

  As shown in FIGS. 16 and 17, the annular flange 47 is provided with an air inlet 71 aligned with the aperture 70 in the circumferential direction. The air inlet 71 includes an aperture penetrating the flange 47 so that an upper portion of the flange 47 and a gap below the flange 47 are circulated between the outer tube 42 and the spout 43. Preferably, as shown, the air inlet 71 includes an upper frustoconical portion 73 and a lower cylindrical portion 72. The air inlet 71 is usually formed by a forming tool such as a pin. When the air inlet 71 has a tapered shape, the forming tool can be easily taken out from the forming raw material. The wall of the outer tube 42 that is proximal to the air inlet 71 is shaped to form a chute 75 that leads from the air inlet 71 to the inlet 45 of the spout 43. As shown in FIG. 17, a slanted shoulder 74 is formed between the air inlet 71 and the chute 75 so that the beverage sprayed from the slot 70 directly over the top surface of the flange 47 just proximal to the air inlet 71. I try not to get it dirty.

  As in the first embodiment, the inner member 3 acts as a load receiving member.

  The procedure for assembling the second type cartridge 1 is the same as that for the first type assembly. However, there are some differences. As shown in FIG. 18, the third portion 21 of the cylindrical extension 18 is not within the support web but within the support rim 67. The shoulder 32 of the cylindrical extension 18 located between the second portion 20 and the third portion 21 hits the upper edge included in the support rim 67 of the inner member 3. In this way, an interfacial zone 124 is formed between the inner member 3 and the outer member 2 that extends substantially the entire circumference of the cartridge 1 and includes a face seal between the cylindrical extension 18 and the support rim 67. Is done. However, since the slot 70 formed in the support rim 67 extends downward through the support rim 67 to a position slightly below the shoulder 68, the seal between the cylindrical extension 18 and the support rim 67 is eliminated. Is not fluid tight. Therefore, when the interface between the cylindrical extension 18 and the support rim 67 is fitted, the slot 70 is changed to the aperture 128, and gas and liquid are communicated between the annular channel 69 and the spout 43. ing. This aperture is typically 0.64 mm wide and 0.69 mm long.

The operation of supplying the beverage with the second type cartridge 1 is similar to the first type, but differs in several respects. Beverage in the radial passage 57 flows downwardly through the passage 57 formed between the webs 54 and enters the annular channel 69 of the cylindrical funnel 40 through the opening 56. After entering the annular channel 69, the beverage is extruded from the aperture 128 under pressure by the back pressure of the beverage collected in the filtration chamber 130 and passage 57. Thus, the beverage is jetted from the aperture 128 and pushed into the expansion chamber formed by the upper end of the spout 43. As shown in FIG. 18, this beverage injection passes through the air inlet 71 as it is. As the beverage enters the spout 43, the beverage jet pressure drops. As a result, air is drawn into the beverage stream as a large number of small bubbles at the same time that air is drawn through the air inlet 71. Beverage jets coming out of the aperture 128 flow downward and gather and reach the outlet 44, where they are poured into a container such as a cup and the bubbles become the desired crema. Thus, both the aperture 128 and the air inlet 71 provide an eductor that acts to take air into the beverage. The beverage flow into the eductor must be kept as smooth as possible to reduce pressure loss. Preferably, the wall of the eductor has a concave surface so that loss due to “wall effect” friction is reduced. The dimensional tolerance of the aperture 128 is small. Preferably, the size for this aperture is set to around 0.02 mm 2 . Hair, fibers or other surface irregularities may be provided in the eductor or near the outlet of the eductor to increase the effective cross-sectional area known to increase air intake.

  19 to 29 show a third type of cartridge 1. A third type of cartridge 1 is specifically designed for use in supplying a soluble product that may be in the form of a powder, liquid, syrup, gel or the like. When an aqueous medium such as water passes through the cartridge 1 during use, the soluble product is dissolved by the aqueous medium or forms a suspension in the aqueous medium. Examples of this beverage include chocolate, coffee, milk, tea, soup, or other products that are reconstituted with water or water-soluble products. Since many of the features of the third type cartridge 1 are the same as those of the first and second types, the same reference numerals are used to indicate the same features. In the following description, differences between the third model, the first model, and the second model will be described. Detailed descriptions of common features that function in the same manner will be omitted below.

  Compared with the outer member 2 of the first and second types, as shown in FIG. 20, the diameter of the hollow and inwardly extending cylindrical extension 18 included in the outer member 2 of the third type is large as a whole. It has become. More specifically, the diameter of the first portion 19 is usually 16 to 18 mm, whereas the outer member 2 of the first and second types is 13.2 mm. Further, the first portion 19 is provided with a convex outer surface 19a, that is, a bulge, as best seen in FIG. The function of this bulge is described below. However, the diameter of the third portion 21 of the cartridge 1 is the same. For this reason, the area of the shoulder 32 is wide in the third type cartridge 1. Normally, the volume of the cartridge 1 is 32.5 ml ± 20% at the time of assembly.

  The number and position of the slots provided at the lower end of the annular wall 13 are also different. Three to five slots are provided. As shown in FIG. 23, in this embodiment, four slots 36 are provided around the manifold 16 at equal intervals. This slot 36 is slightly wider than in the case of the first and second types of cartridges 1 and is 0.35 to 0.45 mm, preferably 0.4 mm wide.

  In other respects, the outer member 2 of the cartridge 1 is the same.

  The structure of the cylindrical funnel 40 included in the inner member 3 is the same as that of the first type cartridge 1, and an outer tube 42, a spout 45, an annular flange 47, and a support web 49 are provided. The only difference is the spout 45, which is shaped with an upper frustoconical portion 92 and a lower cylindrical portion 93.

  Compared to the first and second types, the annular frame 41 is replaced with a skirt portion 80 as shown in FIGS. It is connected to the cylindrical funnel 40 by eight radial struts 87 that surround the cylindrical funnel 40 and couple the cylindrical funnel 40 to or near the annular flange 47. From this skirt portion 80, a cylindrical extension portion 81 extends upward from the strut 87 to define a chamber 90 having an open upper surface. As shown in FIG. 26, the upper rim 91 of the cylindrical extension 81 has an inward profile. An annular wall 82 of the skirt portion 80 extends downward from the strut 87 and defines an annular channel 86 between the skirt portion 80 and the outer tube 42.

  The annular wall 82 includes an outer flange 83 positioned perpendicular to the long axis X at the lower end thereof. The rim 84 includes five apertures 85 that hang downward from the lower surface of the flange 83 and are equally spaced along the rim 84 in the circumferential direction. Therefore, the lower part of the rim 84 has a castle shape.

  By providing an aperture 89 between the struts 87, the chamber 90 and the annular channel 86 are communicated with each other.

  As in the first embodiment, the inner member acts as a load receiving member.

  The procedure for assembling the third type cartridge 1 is similar to the first type assembly, but there are also some differences. As shown in FIG. 29, the outer member 2 and the inner member 3 are not welded to each other, but are pressed together and held by a snap-fitting structure. When the two members are joined, the inward cylindrical extension 18 is received inside the upper cylindrical extension 81 of the skirt portion 80. The inner member 3 is formed in the outer member 2 by the frictional engagement of the convex outer surface 19a of the first portion 19 included in the cylindrical extension 18 with the inward rim 91 of the upper cylindrical extension 81. Retained. When the inner member 3 is in the outer member 2, the mixing chamber 134 is defined outside the skirt portion 80. This mixing chamber 134 stores the beverage ingredient 200 before mixing. Note that the four inlets 36 and the five apertures 85 are staggered in the circumferential direction. Regardless of how the inner member 3 and the outer member 2 are positioned relative to each other, the use of the four inlets 36 and the five apertures 85 ensures that a positional deviation occurs between the inlets and the apertures. The radial position of the two components relative to each other may not be determined or fixed during assembly. The entrance and exit apertures may be other numbers given by the following formula:

Xo = Xi + C
Where Xi = number of entrance apertures
Xo = number of exit apertures
C = 0 or set of integers not including nXi
n = any integer Alternatively, it may be ensured that the inlet and outlet apertures are offset by having an equal number of inlet and outlet apertures arranged unevenly around the cartridge.

  One or more types of beverage ingredients are 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.

  Next, the laminate 5 is attached to the inner member 3 and the outer member 2 as described above in the first and second types.

  In use, water enters the mixing chamber 134 through the four slots 36, similar to the first and second types of cartridges. This water is pushed into the mixing chamber radially inward and mixes with the beverage ingredients stored therein. The product is dissolved or mixed in this water to form a beverage in the mixing chamber 134 that is caused to flow from the aperture 85 into the annular channel 86 by the back pressure of the beverage and water in the mixing chamber 134. The four inlet slots 36 and the five apertures 85 are alternately arranged in the circumferential direction so that the water jet does not enter the aperture 85 directly in the radial direction from the inlet slot 36 and is circulated in the mixing chamber 134. Will occur. This greatly increases the degree and stability of product dissolution or mixing. The formed beverage is pushed upward in the annular channel 86 and enters the chamber 90 through the aperture 89 between the struts 87. Next, when entering the spout 43 from the chamber 90 through the inlet 45 between the support webs 49 and reaching the outlet 44, it is poured into a container such as a cup. It has been found that this cartridge can be applied to beverage ingredients in the form of viscous liquids or gels. In one application, the cartridge 1 contains a liquid chocolate material having a viscosity of 1700-3900 mPa at ambient temperature, 5000-10000 mPa at 0 ° C., and a refractive solid content of 67 Brix degrees ± 3. In another application, the cartridge 1 contains liquid coffee having a viscosity of 70 to 2000 mPa at ambient temperature, 80 to 5000 mPa at 0 ° C., and a total solid content of 40 to 70%. This liquid coffee raw material can contain 0.1 to 2.0% by weight, preferably 0.5 to 1.0% by weight of sodium bicarbonate. Sodium bicarbonate acts to maintain a coffee pH level of 4.8 or lower and to provide a shelf life of a coffee filled cartridge of up to 12 months.

  A fourth type of cartridge 1 is shown in FIGS. The fourth type of cartridge 1 is specifically designed for use in the supply of liquid products such as concentrated liquid milk. Since many of the features included in the fourth type cartridge 1 are the same as those of the first to third types, the same reference numerals are used to indicate the same features. In the following description, the difference between the fourth model and the first to third models will be described. Detailed descriptions of common features that function in the same manner will be omitted below.

  The outer member 2 is the same as that shown in FIGS. 19 to 23 of the third type of cartridge 1.

  The cylindrical funnel 40 of the inner member 3 is similar to the second type of cartridge 1 but differs in several respects. As shown in FIG. 30, the spout 43 has a shape including an upper frustoconical portion 106 and a lower cylindrical portion 107. Three axial ribs 105 are provided on the inner surface of the spout 43 to direct the beverage to be supplied downward to the outlet 44 so that the poured beverage does not turn in the spout. Therefore, the rib 105 acts as a baffle. As with the second type of cartridge 1, an air inlet 71 is provided through the annular flange 47. However, the chute 75 below the air inlet 71 is longer than that of the second type.

  A skirt portion 80 is provided similar to that shown in the third type of cartridge 1 described above. Five to twelve apertures 85 are provided in the rim 84. In the third type of cartridge 1, the number is five, but usually ten apertures are provided.

  An annular ball 100 extending from the flange 83 of the skirt portion 80 is provided. The annular ball 100 includes a flare-type main body 101 having an upper opening 104 opened upward. Four feeding apertures 103 shown in FIGS. 30 and 31 are arranged in the main body 101 at or near the lower end of the ball 100 joined to the skirt portion 80. Preferably, the feeding apertures are arranged around the ball 100 at equal intervals.

  As in the first embodiment, the inner member acts as a load receiving member.

  The laminate 5 is of the type described in the previous embodiments.

  The procedure for assembling the fourth type cartridge 1 is the same as that for the third type assembly.

  The assembly procedure of the fourth type cartridge 1 is the same as that of the third type.

  The operation of the fourth type cartridge 1 is the same as the operation of the third type. As with the first to third types of cartridges, water enters the cartridge 1 and the mixing chamber 134. Here, as described above, water mixes with the liquid product, dilutes it, and is extruded through the aperture 85 under the ball 100 and toward the outlet 44 as described above. As shown in FIG. 34, a certain percentage of the liquid product initially contained in the annular ball 100 is not immediately diluted by water entering the mixing chamber 134. The diluted liquid product in the lower portion of the mixing chamber 134 will exit the aperture 85 rather than being pushed up into the annular ball 100 from the upper port 104. Thus, the liquid product in the annular ball 100 is still relatively concentrated in the first stage of the operating cycle compared to the product in the lower portion of the mixing chamber 134. The liquid product in the annular ball 100 receives gravity and drops from the feed aperture 103 into the product stream that passes through the aperture 85 under the ball 100 in the mixing chamber 134. The annular ball 100 averages the concentration of the diluted liquid product entering the cylindrical funnel 40 by holding a certain amount of concentrated liquid product and periodically pouring it into the liquid flow path during the operating cycle. To act. This is illustrated in FIG. 35a which shows the concentration of milk measured as a percentage of the total solids content during a feed operation cycle of approximately 15 seconds. Line a illustrates the density profile when the ball 100 is provided, and line b illustrates the case of the cartridge without the ball 100. As can be seen from this figure, the concentration profile when the cup 100 is provided is more uniform during the operation cycle, and there is no significant drop in concentration that occurs when the ball 100 is not provided. The initial concentration of this milk is usually 30-35% SS, which is 10% SS at the end of the cycle. Although the dilution rate by this is about 3 times, in this invention, the dilution rate of 1 time-6 times is possible. In the case of other liquid beverage ingredients, this concentration can be changed. For example, in the case of liquid chocolate, the initial concentration is approximately 67% SS, which is 12 to 15% SS at the end of the cycle. Although the dilution rate (ratio of the aqueous medium to the beverage raw material in the blended beverage) is about 5 times, a dilution rate of 2 to 10 times is possible in the present invention. In the case of liquid coffee, the initial concentration is approximately 40 to 67% SS, which is 1 to 2% SS at the end of blending. Although the dilution rate by this is about 20 times-70 times, in this invention, the dilution rate of 10 times-100 times is possible.

  Such beverage is extruded under pressure and passes through the aperture 128 from the annular channel 86 due to the back pressure of the beverage collected in the filtration chamber 134 and chamber 90. Thus, the beverage is jetted from the aperture 128 and pushed into the expansion chamber formed by the upper end of the spout 43. As shown in FIG. 34, this beverage jet passes directly over the air inlet 71. As the beverage enters the spout 43, the beverage jet pressure drops. As a result, air is drawn into the beverage stream as a large number of small bubbles at the same time that air is drawn through the air inlet 71. The beverage jet coming out of the aperture 128 flows downward and gathers, and when it reaches the outlet 44, it is poured into a container such as a cup where the bubbles have a desired foamed appearance.

  Advantageously, the inner member 3, the outer member 2, the laminate 5 and the filter 4 are all separate components and do not individually include meandering passages or narrow gaps so that they can be easily sterilized. Can do. The necessary passages are formed when these components are combined after sterilization. This is particularly important when the beverage ingredient is a product whose main ingredient is a milk ingredient such as a liquid milk concentrate.

  The fourth embodiment of the beverage cartridge is particularly advantageous for the supply of a liquid product whose main ingredient is a concentrated milk ingredient such as liquid milk. In the past, powdered milk products have been provided in the form of sachets, which have been added to pre-prepared beverages. However, in the case of a cappuccino type beverage, it is necessary to whisk the milk. This has been done so far by passing steam through the liquid milk product. However, this requires a steam supply, which increases the cost and complexity of the machine used to prepare this beverage. The use of steam also increases the risk of injury during cartridge operation. Accordingly, the present invention provides a beverage cartridge having therein a liquid product mainly composed of concentrated milk ingredients. It has been found that when the milk product is concentrated, a greater amount of foam can be produced for a specific volume of milk when compared to fresh milk or UHT milk. If this is utilized, the size required for the milk cartridge is reduced. Fresh semi-fat milk contains approximately 1.6% fat and 10% total solids. The concentrated liquid milk preparation according to the invention comprises 0.1 to 12% fat and 25 to 40% total solids. In one exemplary embodiment, the preparation contains 4% fat and 30% total solids. This concentrated milk preparation is suitable for whipping with a low pressure preparation machine as described below. Specifically, this milk frothing is performed using the cartridge of the fourth embodiment described above at a pressure of less than 2 bar, preferably around 1.5 bar.

  Foaming concentrated milk is particularly advantageous for beverages such as cappuccino and milk shakes. Preferably, the milk is passed from the aperture 128 onto the air inlet 71 and optionally the ball 100 is used to be able to froth more than 40%, preferably more than 70% of the milk. In the case of liquid chocolate, foaming in an amount exceeding 70% is possible. In the case of liquid coffee, it is possible to foam more than 70%. The foamability level is measured as the ratio of the foam volume generated to the volume of the formulated liquid beverage ingredient. For example, when 138.3 ml of beverage is prepared and 58.3 ml of the beverage is foamed, the foamability is [58.3 / (138.3-58.3)] × 100 = 72.9%. . The foamability of this milk (and other liquid ingredients) is enhanced by providing balls 100 as can be seen in FIG. 35b. The foamability (line a) of milk prepared by providing the ball 100 is higher than the foamability (line b) of milk prepared without providing the ball. This is because the milk foaminess is directly proportional to the milk concentration, and as shown in FIG. 35a, the ball 100 maintains a high milk concentration for the majority of the operating cycle. It is also known that the foaminess of milk is directly proportional to the temperature of the aqueous medium, as shown in FIG. 35c. Therefore, it is advantageous to provide the balls 100 because more milk remains in the cartridge until near the end of the operating cycle when the aqueous medium is hottest. This further improves foamability.

  The cartridge of the fourth embodiment is also advantageous for formulating a liquid coffee product.

It can be seen that the beverage cartridge embodiment of the present invention can effectively improve the stability of the beverage to be dispensed as compared to the prior art cartridges. Referring to Table 1 below, the yields obtained by brewing 20 samples for each of cartridge A and cartridge B containing roasted and ground coffee are shown. The cartridge A is a beverage cartridge according to the first embodiment of the present invention. The cartridge B is a beverage cartridge according to the prior art described in Patent Document 1 by the present applicant. The refractive index of the brewed beverage is measured in Brix degrees, which is converted to a soluble solids ratio (% SS) using a standard table and formula. In the following examples:
% SS = 0.7774 * (Brix degree value) +0.0569
% Yield = (% SS * decoction amount (g)) / (100 * coffee weight (g))
It is.

  When t-test statistical analysis was performed on the above data, the following results were obtained.

  From this analysis, the yield stability comparable to the decoction concentration is compared to the standard deviation of 2.24% for the cartridge according to the prior art for the cartridge according to the present invention with a standard deviation of 0.88%, It can be seen that it was significantly higher (95% confidence level). This means that the strength of the beverage supplied by the cartridge according to the invention is reproducible and uniform. This is preferable for consumers who want to taste the same beverage over and over and do not want to change the strength of the beverage.

  Although the first and second types of cartridges are assembled by welding, they can be similarly assembled by the snap-fitting structure according to the present invention. For example, the outer member 2 may include a formation that cooperates with the periphery of the annular frame 41 forming the snap fitting portion.

  Barrier coatings may be applied to the cartridge materials described above to improve protection against oxygen and / or moisture and / or other contaminant intrusions. By applying this barrier coating, it is possible to improve the protection against the leakage of beverage ingredients from the cartridge and / or to reduce the extent of extract exudation from the cartridge material that may adversely affect the beverage ingredients. The material of the barrier coating can be selected from the group consisting of PET, polyamide, EVOH, PVDC or metallized material. Several mechanisms are available for the application of barrier coatings, including but not limited to vapor deposition, vacuum deposition, plasma coating, coextrusion, in-mold labeling, and two-stage / Multi-stage molding is exemplified.
