Description

Technical Field

[0001] The present disclosure generally relates to an electrically operated beverage or food preparation system by which a beverage or food is prepared from pre-portioned capsules. Background Art

[0002] A system for preparing a beverage comprises a beverage preparation machine and a capsule. The capsule comprises a single serving of a beverage forming precursor material, for example ground coffee or tea. The beverage preparation machine is arranged to perform a beverage preparation process on the capsule, typically by exposing pressurized, heated water to the precursor material. Processing the capsule in this manner causes the precursor material to be at least partially extracted from the capsule as a beverage.

[0003] This configuration of beverage preparation machines is increasingly popular due to: 1) enhanced user convenience compared to conventional beverage preparation machines (e.g., compared to manually operated stovetop espresso machines), and 2) enhanced beverage preparation processes, wherein: preparation information encoded by a code on a capsule is read by the machine to define a recipe; and the recipe is used by the machine to optimize the preparation process in a capsule-specific manner. Specifically, the encoded preparation information may include operating parameters selected in the beverage preparation process, including: fluid temperature; fluid pressure; preparation duration; and fluid volume.

[0004] EP 2594171 A1 discloses a machine for reading a code from the underside of a flange of a capsule. A disadvantage is that the code cannot be applied to more flexible parts of the capsule (e.g., a closing member) because the code can only be read from a rigid support. Furthermore, the code is configured to be read based on its formation on an optically opaque carrier material.

[0005] Thus, despite the effort that has been put into developing the described systems, further improvements are needed. Summary of the invention

[0006] The present disclosure provides a container for use with a machine for preparing beverages and / or food products. In an embodiment, the container comprises a body portion including a storage portion for containing a precursor material.

[0007] In an embodiment, the container includes a closure member to close the storage portion (e.g., for a container arranged as a capsule). In an embodiment, the closure member overlaps the precursor material contained in the storage portion. As used herein, the term "overlap" about the closure member and the precursor material may refer to a plane with the closure member having a normal that intersects with the precursor material. For example, the normal may be in the depth direction, and the closure member may extend on a plane defined by the transverse direction and the longitudinal direction. In an embodiment, the storage portion includes a cavity extending in the depth direction from the closure member. In an embodiment, the main body includes a flange portion connecting the storage portion and the closure member. In an embodiment, the flange portion and / or the closure member extend in a plane defined by the transverse direction and the longitudinal direction. The cavity of the storage portion extends in the depth direction from the flange. In an embodiment, the flange is planar. As used herein, the term "planar" about the flange may refer to a flange being arranged to extend completely in the transverse direction and the longitudinal direction, or extending substantially in the direction (e.g., having a main component in these directions opposite to the depth direction).

[0008] In an embodiment, the body portion is formed from walls that are joined and / or folded at seams (eg, for a container arranged as a pouch).

[0009] The container includes a code for (e.g., configured to) store preparation information. The preparation information can be used by the machine to process precursor materials. In an embodiment, the code is configured to be read by the code reading system of the machine, and the code reading system includes an illumination system (e.g., by illumination) that projects emitted light to the code for reading, and a camera system (e.g., for obtaining a digital image of the code when subjected to the emitted light) may be included. The preparation information can be related to the container, for example, it is selected to correspond to the precursor material and / or the container size, so that the processing unit of the machine can be controlled in a process that is particularly suitable for a specific container. In an embodiment, the closed member includes a code, for example, formed as one or more layers thereof. As used herein, the term "code" can refer to one or more repetitions of a code, each code storing preparation information and being individually readable. In an embodiment, the code and the associated layer extend in a plane defined by a transverse direction and a longitudinal direction, and have a penetration thickness in a depth direction.

[0010] In an embodiment, the code is arranged to overlap with the precursor material (e.g., the normal of the plane in which the code is arranged extends into the precursor material so that the emitted light from the illumination system is projected into the precursor material). For example, it is arranged on the closure member or on the wall of the pouch. In an embodiment, the code is arranged not to overlap with the precursor material. For example, it is arranged on a flange portion or a seam of the pouch.

[0011] In an embodiment, the emitted light from the illumination system has a wavelength greater than 700nm or 800nm. The emitted light may be substantially within the infrared wavelength. The emitted light may have a peak value between 800nm ​​and 1000nm, with a HWHM of ±100nm or 50nm or 25nm. The camera system may be configured accordingly to obtain digital images within the band. The camera system may include a high pass filter to pass wavelengths above 700nm or 800nm. The emitted light and / or the camera system may operate at a maximum wavelength of 1200nm or 1500nm.

[0012] [Support layer transparent to emitted light]

[0013] In an embodiment, the container includes a support layer that supports the code. In an embodiment, the support layer is made of a material that is at least partially transparent to (e.g., at least partially transparent to) emitted light from the lighting system (e.g., such that some or all of the emitted light can pass through the support layer). In an embodiment, the code includes: an absorption layer configured to absorb the emitted light; and a reflective layer configured to reflect the emitted light, the reflective layer being arranged to reflect the emitted light before the emitted light is transmitted to the support layer.

[0014] By implementing a transparent support layer (the support layer is made of a material that is at least partially transparent to the emitted light from the illumination system), the support layer can be thin so that it can support the layers forming the closed member while being penetrable by a machine (for processing of the precursor material), and / or the support layer can be made of a biodegradable material (which is typically optically transparent). Examples include paper or biodegradable plastics. The reflective layer can compensate for the transparency of the support layer by reflecting the emitted light before it reaches the support layer, while the absorbing layer can absorb the emitted light, the combination of these two layers allowing the identification of cells of the code against a contrasting background. In examples without a reflective layer, the emitted light may otherwise be transmitted through the support member and absorbed by the precursor material, which may not form a suitable contrast with the absorbing layer.

[0015] In an embodiment, the reflective layer is continuous.By realizing the reflective layer arranged as one piece (eg, over an area comprising the absorbent layer), a large uniform reflection of the emitted light below the absorbent layer can be achieved, which can improve the readability of the code.

[0016] In an embodiment, the reflective layer is connected (including directly connected or connected via an adhesive or other connection means) to the support layer to abut the support layer. By connecting the reflective layer to the support layer, it can be ensured that the emitted light is reflected before being transmitted through the support layer.

[0017] In an embodiment, the support layer extends in a plane defined by the transverse direction and the longitudinal direction and has a through thickness in a depth direction extending from an outer surface (e.g., an outer surface of a closure member, or in other embodiments, a portion of a container comprising the code. The outer surface may comprise an exposed surface of a protective layer, or in embodiments without a protective layer, the code comprises an exposed surface of an absorbent layer.

[0018] In an embodiment, the reflective layer is arranged to overlap the entire support layer when viewed in said plane.By arranging the reflective layer to overlap the entire support layer (eg in the region of the absorbing layer comprising the code), it can be ensured that the emitted light is reflected before being transmitted through the support layer.

[0019] In an embodiment, the absorption layer is arranged between the reflective layer and the outer surface in the depth direction, so that the absorption layer is closest to the outer surface relative to the reflective layer, and the reflective layer is arranged between the support layer and the outer surface in the depth direction. By arranging the absorption layer closest to the outer surface, it can absorb the emission light that is not interrupted by the reflective layer, wherein the reflective layer is arranged to then reflect the emission light and prevent the emission light from being absorbed by the support layer and / or the precursor material.

[0020] In an embodiment, the portion of the container including the support layer and the code (and other layers, when present, including barrier layers and protective layers, such as the entire closure member) is configured to be penetrated by one or more penetrators when subjected to a force greater than a threshold value, each penetrator having a tip of 70 to 30 degrees. The tip can apply a full circle, the radius of which corresponds to the tip angle. The threshold force of each penetrator can be 7N to 10N or 5N to 15N. Alternatively, the threshold can be a combined force of 700N (± 20% or ± 30%) applied to all penetrators, for example, there can be 88 or 50 to 150 penetrators in total.

[0021] By achieving penetration at the threshold, the support layer can be penetrated by the machine during processing, but will not be accidentally penetrated when subjected to treatment. In an embodiment, the support layer is a primary support layer, for example, it is capable of resisting a higher tensile strength than the other layers. In an embodiment, the support layer has a thickness of 50 microns to 150 microns.

[0022] In an embodiment, the support layer is transparent to at least 30% to 80% of the emitted light from the lighting system. Due to the transparency to the emitted light, the support layer can be thin, so that the support layer can be machine-penetrable and / or biodegradable. In an embodiment, the precursor material can absorb at least 60% of the emitted light from the lighting system. In an embodiment, the support layer includes one or more of the following: paper-based; aluminum-based; plastic-based.

[0023] In an embodiment, the absorbing layer comprises carbon black and the reflecting layer does not comprise carbon black. The supporting layer may also not comprise carbon black. In an embodiment, the absorbing layer is formed by a black ink comprising carbon black and the reflecting layer is formed by one or more inks (e.g., white ink) that do not comprise carbon black. By using carbon black as an absorber and an ink lacking carbon black as a reflector, the code can be conveniently read in the infrared spectrum. These layers can also be conveniently formed by printing using inks.

[0024] In an embodiment, the reflective layer is configured to diffusely reflect the emitted light. The reflectivity of the emitted light can be at least 70%. By diffusely reflecting the light, a convenient uniform background (e.g., white) can be provided for the code (because another case of specular reflection may be read as a saturated white light spot). In an embodiment, the absorbing layer has a reflectivity of less than 10%. When reading the code, the low reflectivity compared to the reflective layer can provide sufficient contrast between the layers. In an embodiment, the thickness of the absorbing layer and / or the reflective layer is 1 micron to 5 microns.

[0025] [Support layer with specular reflection]

[0026] In an embodiment, the support layer is configured for specular reflection of emitted light from the illumination system, and the code comprises an absorption layer configured to absorb the emitted light and a reflective layer configured to diffusely reflect the emitted light, the reflective layer being arranged to reflect the emitted light before the emitted light is transmitted to the support layer.

[0027] By implementing the support layer for specular reflection (e.g., such that at least 50%, or 70%, or 80% of the light reflected from the support layer is specularly reflected), a specific surface finish can be provided. The specular reflection can also illuminate the code to improve reading, however the reflective layer can reflect a large portion of the emitted light before it is transmitted to the support layer, and also reflect any emitted light reflected from the support layer so that the code reader does not see the specular reflection, which otherwise may cause the digital image of the code to be saturated. The specular reflection can be achieved by a specific smoothness or other surface finish, such as aluminum or other polished / smooth metal.

[0028] In an embodiment, the reflective layer is continuous, the reflective layer is connected to the supporting layer to be adjacent to the supporting layer; and the supporting layer extends in a plane defined by the lateral direction and the longitudinal direction and has a through thickness in the depth direction, and wherein the reflective layer overlaps the entire supporting layer when viewed in said plane.

[0029] In an embodiment, the support layer extends in a plane defined by the transverse direction and the longitudinal direction, and has a through thickness in a depth direction extending from the outer surface, and: the absorption layer is arranged between the reflective layer and the outer surface in the depth direction so that the absorption layer is closest to the outer surface relative to the reflective layer; and the reflective layer is arranged between the support layer and the outer surface in the depth direction. In an embodiment, the absorption layer is arranged to overlap the entire reflective layer when viewed in the plane.

[0030] In an embodiment, the support layer is configured to provide at least 60%, 80%, or 90% of the tensile strength of the associated laminate including the support layer, the reflective layer, and the absorbing layer (and any other layers that may be optionally present, such as protective layers and barrier layers). By implementing the support layer to provide the primary structural support in a tensile state compared to the other layers present, the support layer can provide structural strength to resist accidental penetration through handling, and provide suitable support to enable, for example, reading of the supported code without deformation. In an embodiment, the support layer has a thickness of 2 microns to 50 microns or 5 microns to 10 microns.

[0031] In an embodiment, the support layer has a reflectivity of at least 70%.By implementing the support layer to reflect a significant amount of incident emitted light, the code can be illuminated for more convenient reading.In an embodiment, the support layer is optically opaque.

[0032] In an embodiment, the reflective layer is configured to diffusely reflect the emitted light. The reflectivity of the emitted light can be at least 70% or 80%. By diffusely reflecting the light, a convenient uniform background (e.g., white) can be provided for the code (because another case of specular reflection may be read as a saturated white light spot). In an embodiment, the absorbing layer has a reflectivity of less than 10%. When reading the code, the low reflectivity compared to the reflective layer can provide sufficient contrast between the layers. In an embodiment, the thickness of the absorbing layer and / or the reflective layer is 1 micron to 5 microns. The reflective layer can have a white surface. The reflective layer can be configured for diffuse reflection, for example, with a surface finish to diffusely reflect the wavelength of the emitted light, such as a rough matte surface.

[0033] In an embodiment, the reflective layer is configured to diffusely reflect the emitted light. At least 60% or 70% or 80% of the emitted light may be reflected as diffuse light. Diffuse light may be defined as light of substantially uniform intensity due to scattering caused by the surface of the reflective layer.

[0034] In embodiments, the reflective layer may be partially transparent to the emitted light, including being transparent to less than 20% or 30% of the emitted light, including an optional minimum transparency of 5% or 10%. By enabling a portion of the emitted light to be transmitted through the reflective layer, the transmitted light may be transmitted to the support layer. For a mirrored support layer, such transparency may enable the surface finish of the support layer to be observed through the code. Such transparency may be achieved by printing with white ink.

[0035] In embodiments, the absorbing layer has a reflectivity of less than 10% or 30%.

[0036] In an embodiment, the support layer is aluminum based. The aluminum support layer may be food safe and / or provide a barrier to moisture and / or oxygen. The aluminum base may include aluminum polymers, for example including PET12u / Alu30 / BOPP30.

[0037] [Precursor material for the absorbent layer]

[0038] In an embodiment, the container includes: a code arranged to overlap with a precursor material; and a support layer supporting the code, the support layer being at least partially transparent to emitted light from an illumination system, wherein the code includes a reflective layer configured to reflect the emitted light before it is transmitted to the support layer, and the precursor material is arranged to absorb the emitted light.

[0039] By implementing a support layer transparent to the emitted light and a precursor material absorbing said emitted light, the precursor material can be visible in the digital image as a dark surround, and the reflective layer forms cells of the code which are visible as light areas on the dark surround. Dedicated absorbing layers in the code or other components of the container (e.g. a closing member) can be omitted, which can make the code more convenient to form.

[0040] In an embodiment, the precursor material may absorb at least 60% of the emitted light from the illumination system.By implementing the precursor material to absorb a majority of the emitted light, such as 50% or 70% or more, the precursor material may provide a uniform, relatively dark background in the image.

[0041] In an embodiment, the precursor material comprises ground coffee. Ground coffee has been found to have a high absorptivity for the selected wavelengths of emitted light disclosed herein due to its high carbon black content.

[0042] In an embodiment, the reflective layer is configured to diffusely reflect the emitted light. By implementing the reflector to substantially diffusely reflect the emitted light, the cells of the code can be precisely readable, for example, as opposed to specular reflections that may cause saturation of the digital image. The diffuse reflection can be uniform across the reflective layer, including having minimal specular reflection (e.g., less than 10% or 5% is specular reflection).

[0043] In an embodiment, the reflective layer is configured to have a reflectivity of at least 60% or 70% or 80% of the emitted light.By implementing the reflective layer to have a relatively high reflectivity to the precursor material, there can be a suitable contrast between the reflective layer and the precursor material in the image.

[0044] In an embodiment, the reflective layer is formed from one or more inks that do not contain carbon black, and the precursor material contains carbon black. By implementing the reflective layer so as not to contain carbon black, the presence of carbon black in the precursor material can be used to improve the contrast of the reflective layer when subjected to emitted light from a light source having a wavelength greater than 700nm or 800nm, and the camera system is arranged to sense light of said wavelength.

[0045] [Information Carrying Layer]

[0046] In an embodiment, the code is readable by a code reading system of a machine, the code reading system comprising: an illumination system for projecting emitted light greater than 700nm or 800nm ​​onto the code; and a camera system for obtaining a digital image of the code operating at a wavelength greater than or 700nm or 800nm, the code being arranged to absorb and / or reflect the emitted light so as to capture the digital image by the camera system; and an information bearing layer comprising container information visible at visible wavelengths and having a relatively low absorptivity and / or reflectivity to the emitted light, wherein the information bearing layer is arranged to be effectively close to the code layer to conceal the code. The container information of the information bearing layer can be arranged to be readable by a user.

[0047] By implementing the code to be readable at a substantially infrared wavelength (e.g., above 700 nm and up to 100 μm), the reading of the code can be uninterrupted by the information bearing layer, which is visible at a visible wavelength (e.g., 380 nm to 700 nm) but does not absorb (including substantially absorb) or reflect (including substantially reflect) the wavelength. In addition, since the information bearing layer is visible in the visible band, it can be used to present information to the user while reducing the visibility of the code in the visible band.

[0048] As used herein, the term "container information" may refer to information related to the container and / or precursor material, for example, it may include one or more of the following: an identifier used by a user to identify the container or a beverage prepared therefrom; information used by a user to select operating parameters of the machine, such as a portion of milk and / or milk conditioning parameters, or the volume of water required by the container for the preparation process (and which must be present in the machine), or the volume of the prepared beverage, so that the user can select a suitable cup size; information identifying the manufacturer of the container; expiration information; and other information.

[0050] As used herein, the term "hidden code" may refer to an information bearing layer arranged to reduce the visibility of the code in the visible band compared to a code without the information bearing layer, which may be achieved by making the object of the information bearing layer have a reference size (which may be the largest size of the object) at least 2 to 10 times the reference size of the code (which may be the side length or diameter of the code). The reference size of the object may be a maximum of 30 times the reference size of the code.

[0051] In an embodiment, the code is not readable at visible wavelengths due to the presence of the information bearing layer in the digital image. Such an arrangement may define the code as hidden.

[0052] In an embodiment, the information bearing layer has an absorptivity of less than 20% for the emitted light and a reflectivity of less than 30% for the emitted light. By implementing the information bearing layer to have such low absorptivity and low reflectivity for the emitted light and / or wavelengths at which the camera system operates, the information bearing layer can have a reduced appearance / no appearance in the digital image and therefore have low / no interference with code reading.

[0053] In an embodiment, the information bearing layer is continuous. By implementing the information bearing layer arranged as one piece (e.g., over an area including an absorbent layer), the information carrying capacity can be large while conveniently hiding the code. In an embodiment, the information bearing layer is adjacent to the code. By implementing the information bearing layer as directly adjacent to the code (e.g., its absorbent layer and / or reflective layer), the code can be appropriately hidden.

[0054] In an embodiment, the information bearing layer extends in a plane defined by the transverse direction and the longitudinal direction and has a through thickness in a depth direction extending from the outer surface. In an embodiment, the information bearing layer is arranged to overlap the entire code when viewed in said plane. By implementing the information bearing layer to overlap the code (e.g., its absorbing layer and / or reflecting layer), the code can be appropriately hidden.

[0055] In an embodiment, the code (eg, its absorbent layer) is closest to the outer surface relative to the information bearing layer. By arranging the code (eg, the absorbent layer) closer to the outer surface than the information bearing layer, the code can be read with minimal interference from the information bearing layer.

[0056] In an embodiment, the code includes an absorption layer configured to absorb emitted light and a reflective layer configured to reflect emitted light; the reflective layer is configured to reflect visible wavelengths; the information bearing layer is arranged between the reflective layer and the outer surface of the closed member in the depth direction; and the absorption layer is arranged between the reflective layer and the outer surface of the closed member in the depth direction. By implementing the reflective layer to reflect visible wavelengths including all visible wavelengths (as well as visible wavelengths of emitted light from the illumination system), so that it appears white, a uniform background can be provided for the information bearing layer to be observed thereon.

[0057] In an embodiment, the reflective layer extends in a plane defined by the transverse direction and the longitudinal direction and has a through thickness in the depth direction, and: the reflective layer is continuous and overlaps the information bearing layer in said plane.

[0058] In an embodiment, the information bearing layer includes one or more objects that provide the information. The objects can be formed of one or more different colors. The objects can provide information to the user while hiding the code. Multiple colors (e.g., formed of cyan, magenta, and yellow inks) can increase the information carrying capacity.

[0059] In an embodiment, the container includes a color layer arranged to impart a background color. In an embodiment, the color layer is arranged between the reflective layer and the outer surface in the depth direction. In an embodiment, the color layer is arranged between the reflective layer and the information bearing layer in the depth direction. With this arrangement, the color layer can impart a background color (e.g., brown) different from the reflective layer (which can be white) to the information bearing layer. In an embodiment, the color layer is continuous (e.g., a piece on the reflective layer and / or the information bearing layer). In an embodiment, the color layer is formed by one or more inks that do not contain carbon black. In an embodiment, the information color layer is arranged to overlap with the entire information bearing layer when viewed in the plane.

[0060] In an embodiment, the container comprises a protective layer through which the code can be read by a code reading system. In an embodiment, the protective layer is transparent (including substantially transparent) to the emitted light from the illumination system and the emitted light reflected from the reflective layer, i.e., is made of a material that is at least partially transparent to the emitted light from the illumination system.

[0061] In an embodiment, the protective layer is moisture resistant and / or oxygen resistant. By implementing the protective layer to provide a barrier to moisture and / or oxygen, the code can be protected from degradation and / or food safety can be ensured.

[0062] In an embodiment, the protective layer comprises a layer formed from regenerated cellulose, such as cellophane DN 22. The regenerated cellulose may be biodegradable, while being food safe and suitably optically transparent.

[0063] In an embodiment, the code (e.g., the absorption layer and / or the reflective layer) is formed by printing on the protective layer (including printing on the protective layer directly or via an intermediate layer). By printing the layer of the code directly onto the protective layer with a printing device, the closing member (or in other embodiments, other parts of the container including the code) can be conveniently formed with high precision.

[0064] In an embodiment, the container includes a barrier layer arranged to confine the precursor material, wherein the barrier layer is moisture and / or oxygen resistant and may include a biodegradable polymer. The barrier layer may provide isolation of the precursor material from the support layer and / or other component layers, which may improve food safety and / or increase the life of the layer.

[0135] refer to Figure 4 and Figure 5A first example of a container handling unit 20 is for handling containers arranged as capsules 6 (a suitable example of a capsule is shown in Figure 7 The container handling unit 20 is configured as an extraction unit 32 to extract the beverage from the capsule 6. The extraction unit 32 includes a capsule holding portion 34 and a closing portion 36. The extraction unit 32 can be moved to a capsule receiving position ( Figure 4 ), in which the capsule receiving position, the capsule holding portion 34 and the closing portion 36 are arranged to receive the capsule 6 therebetween. The extraction unit 32 can be moved to the capsule extraction position ( Figure 5 ), in which capsule extraction position the capsule holding portion 34 and the closing portion 36 form a seal around the capsule 6 and beverage can be extracted from the capsule 6. The extraction unit 32 may be actuator driven or manually movable between said positions.

[0136] The outlet 30 of the fluid conditioning system 22 is arranged as an injection head 38 on the capsule holding part 34 to inject the conditioned fluid into the capsule 6 (usually under high pressure) at the capsule extraction position. The beverage outlet 40 on the closing part 36 is arranged to capture the extracted beverage and convey the extracted beverage from the extraction unit 32.

[0137] The extraction unit 32 is arranged to prepare a beverage by applying a pressurized (e.g., 10 to 20 bar), heated (e.g., 50 to 98 degrees Celsius) fluid to the precursor material within the capsule 6. The pressure increases over a predetermined amount of time until it exceeds the rupture portion of the capsule 6 (at Figure 4 and Figure 5 This causes the portion to rupture and dispense the beverage into the beverage outlet 40.

[0138] In a variant embodiment not shown, although the injection head and the beverage outlet are shown as being arranged on the capsule holding part and the closing part, respectively, they may be arranged alternatively, including: the injection head and the beverage outlet are arranged on the closing part capsule holding part and; or both are arranged on the same part. In addition, the extraction unit may include two parts arranged as the capsule holding part, for example for a capsule symmetrical around a flange, including Professional capsules. Examples of suitable extraction units are provided in EP 1472156 A1 and in EP 1784344 A1 and provide hydraulically sealed extraction units.

[0139] In a second example of a container handling unit (not illustrated), an extraction unit similar to the first example is provided, however, the extraction unit operates at a lower pressure and by centrifugation. Examples of suitable capsules are Vertuo capsules. A suitable example is provided in EP 2594171 A1. In such an example (or indeed other examples), the guide portion may be omitted and the container manually loaded into the extraction unit.

[0140] In a third example (not illustrated), the capsule processing unit operates by dissolving a beverage precursor selected to dissolve under high pressure and temperature fluid. The extraction unit is arranged similarly to the first and second examples, however, the pressure is lower and therefore a sealed extraction unit is not required. Specifically, the fluid may be injected into the cover of the capsule and the rupture portion is located in the base of the storage portion of the capsule. Examples of suitable capsules are Dolce Gusto capsules. Examples of suitable extraction units are disclosed in EP 1472156 A1 and in EP 1784344 A1.

[0141] In a fourth example (not illustrated) in which the container is arranged as a sac, the container handling unit implements an extraction unit operable to receive a sac and inject a fluid from a fluid conditioning system at an inlet of the sac. The injected fluid mixes with a precursor material within the sac to at least partially prepare a beverage, which leaves the sac via an outlet of the sac. An example of such an arrangement is provided in WO2014125123 A1.

[0142] In a fifth example (not illustrated), the container processing unit is arranged as a mixing unit to prepare a beverage or food precursor stored in a container, which is a container for consumption from an end user. The mixing unit includes an agitator (e.g., a planetary mixer; a spiral mixer; a vertical cutting mixer) to mix the beverage or food precursor in the container; and a heat exchanger to heat / cool the beverage or food precursor. The fluid supply system can also supply fluid to the container. An example of such an arrangement is provided in WO2014067987A1.

The distribution and dissolving unit is arranged to extract a single portion of a beverage or food precursor from the storage portion of the machine (which may include any multi-portioned container, which includes a pouch or box). The distribution and dissolving unit is arranged to mix the extracted single portion with the conditioned fluid from the fluid conditioning system, and the beverage or food is distributed in a container. The example of this type of arrangement is provided in EP14167344A.

[0144] [Code reading system]

[0145] refer to Figure 4 and Figure 5The code reading system 18 is arranged to read a code 44 arranged on the cover of the container 6. The code reading system 18 is integrated with the extraction unit 32 of the first example of the container handling unit 20. The code 44 is read by the extraction unit 32 at the capsule extraction position (e.g. Figure 4 shown).

[0146] The code reading system 18 includes a code reader 46 having an image capture unit and a read head that houses the image capture unit for capturing a digital image of the code 44. The image capture unit includes an illumination system and a camera system. Examples of suitable image capture units include the Sonix SN9S102; Snap Sensor S2 imager; oversampled binary image sensor; other similar systems.

[0147] The electrical circuitry 18 includes image processing circuitry (not illustrated) to identify codes in digital images and extract preparation information. An example of image processing circuitry is a Texas InstrumentsTMS320C5517 processor running a code processing program.

[0148] In a variant embodiment not illustrated, the code reading system is separated from the container handling unit, including: the code reading system is arranged in a channel in which a user places a container and conveys the container to the container handling unit; the code reading system is arranged to read a code on a container positioned to receive a beverage from a beverage outlet of the dispensing and dissolving unit. In another variant embodiment not illustrated, the code reading system is arranged to read a code at a different position of the container (e.g., on a flange of a restraining portion). In another variant embodiment not illustrated, the code is a one-dimensional code and is read by relative movement between a code reader and the code to generate a code signal.

[0149] [Control electrical circuit system]

[0150] refer to Figure 6 , the electrical circuit system 16 is implemented to control the electrical circuit system 48 to control the processing unit 14 to perform the preparation process. Figure 6 In the embodiment of the present invention, for illustrative purposes, the processing unit 14 is illustrated as a first example, and the processing unit includes a container processing unit 20 and a fluid supply unit 22.

[0151] The electrical circuit systems 16, 48 at least partially implement (e.g., in combination with hardware): an input unit 50 for receiving input from a user confirming that the machine 4 will perform a preparation process; a processor 52 for receiving input from the input unit 50 and providing a control output to the processing unit 14; and a feedback system 54 for providing feedback from the processing unit 54 during the preparation process, which feedback can be used to control the preparation process.

[0152] The input unit 50 is implemented as a user interface, which may include one or more of the following: a button, such as a joystick button or a push button; a joystick; an LED; a graphic or character LDC; a graphic screen with touch sensing and / or screen edge buttons; other similar devices; a sensor for determining whether a container has been supplied to the machine by a user.

[0153] The feedback system 54 may implement one or more of the following or other feedback control-based operations:

[0154] A flow sensor is used to determine the outlet 30 (at Figure 3 Flow rate / volume of the fluid (shown in ), which can be used to meter the correct amount of fluid to the container 6 and thus adjust the power to the pump 26;

[0155] a temperature sensor to determine the temperature of the fluid to the outlet 30 of the fluid supply unit 22, which temperature sensor may be used to ensure that the temperature of the fluid to the container 6 is correct and to regulate the power to the heat exchanger 28 accordingly);

[0156] a level sensor to determine whether the level of fluid in the reservoir 24 is sufficient for the preparation process;

[0157] A position sensor, the position sensor is used to determine the position of the extraction unit 32 (eg, a capsule extraction position or a capsule receiving position).

[0158] It will be appreciated that the electrical circuit system 16, 44 is suitably adapted to other examples of the processing unit 14, such as for the second example of a container processing system, where the feedback system may be used to control the rotational speed of the capsule.

The flange portion 60 is disposed at the junction of the storage portion 58 and the closure member 56 and comprises a planar extension of the storage portion 58 that overlaps a portion of the closure member secured thereto to hermetically seal the precursor material. The flange portion 60 extends in a plane defined by the transverse direction 102 and the longitudinal direction 100. Thus, the closure member is planar in said plane.

[0166] The capsule 6 is of circular cross-section, making it rotationally symmetrical about the axis 108. In this way, the user can present the capsule to the machine 2 in any orientation about the axis 108. The capsule 6 has a diameter of 53 mm, measured across the outer periphery or the inner periphery of the flange portion 60 in the plane of the flange portion 60. The capsule 6 can be configured to have different sizes, characterized by different depths, for example: 7 mm; 12 mm; 15 mm; 18 mm; and 21 mm.

[0167] In a variant embodiment not illustrated, the closing member may be arranged to be convex or concave relative to the storage portion. For example, for a convex arrangement, the center of the closing member may extend into the storage portion by up to 1 mm ± 10% or 20% in the depth direction. The minimum depression may be 0.2 mm. For example, for a concave arrangement, the center of the closing member may extend away from the storage portion by up to 4 mm ± 10% or 20% in the reverse depth direction. The minimum depression may be 0.5 mm.

[0168] In non-illustrated variant embodiments: the main body portion includes a flange portion that is not integrally formed with the storage portion and connected to the storage portion; the main body portion includes an omitted flange portion, for example, the closing member is wrapped around the storage portion; the container can be a non-rotationally symmetrical shape, such as a square cross-section or other shape; the capsule is alternatively sized to include an outer circumference or inner circumference across the flange portion of 40mm to 70mm or 53mm±10% or 20%, and a depth of any of the described depths±10% or 20%; the thickness of the storage portion may have a thickness of 0.1mm to 0.4mm or 0.2±20% or 30%; the thickness of the closing member may have a thickness of 0.05mm to 0.3mm or 0.15±20% or 30%; and the storage portion and / or the closing member may be made of or include different materials, for example, including plastic or aluminum-based materials.

[0169] [Code layout]

[0170] refer to Figure 7 The code 44 may be arranged on the outer surface of the container 6 at any suitable location such that the code can be read by the code reading system 18 .

[0171] In a first example, the code 44 is arranged at a central area of ​​the closure member 56. Thus, the code can be read by any code reader aligned with the center of the container. In a second example, the code is replicated throughout the closure member so that it can be read from any external location on the closure member 56. With such an arrangement, the closure member does not require any specific alignment with the storage portion, which simplifies the cutting and assembly process of the container 6.

[0172] In a variant embodiment not illustrated, the code may be arranged on the flange portion 60 (including on either side) and on the storage portion 58. The code may also be arranged on the closing member, but not on the intermediate area.

[0173] [Process for preparing beverages]

[0174] refer to Figure 8 , illustrating a process for preparing a beverage / food from a precursor material:

[0175] Box 70 : The user supplies the container 6 to the machine 4 .

[0176] Box 72: The electrical circuit system 16 (eg, the input unit 50 thereof) receives a user instruction to prepare a beverage / foodstuff from a precursor, and the electrical circuit system 16 (eg, the processor 52) initiates the process.

[0177] Box 74: The electrical circuit system 16 controls the processing unit 14 to process the container (eg, in the first example of the container processing unit 20, the extraction unit 32 receives the capsule from the location ( Figure 4 )Move to the capsule extraction position ( Figure 5 )).

[0178] Box 76: The electrical circuit system 16 controls the code reading system 18 to provide a digital image of the code 6 of the container.

[0179] Block 78: The code processing circuitry of the electrical circuitry 16 processes the digital image to extract the preparation information.

[0180] Box 80: The electrical circuit system 16 executes the preparation process based on the preparation information by controlling the processing unit 14. In the first example of a processing unit, this includes controlling the fluid conditioning system 22 to supply fluid to the container processing unit 20 at the temperature, pressure and duration specified in the preparation information.

[0181] The electrical circuit system 16 then controls the container handling unit 20 to move from the capsule extraction portion through the capsule ejection position to eject the container 6 and back to the capsule receiving position.

[0182] In alternative embodiments not shown: the above-mentioned frames may be executed in a different order, for example, frame 72 may be executed before frame 70 or frame 76 may be executed before frame 74; a frame may be omitted, for example, frame 70 may be omitted when the machine stores capsule boxes.

[0183] Box 76 and box 78 may refer to code reading and processing. Box 80 may be referred to as a preparation process. Electrical circuit system 16 includes instructions for the preparation process (or multiple preparation processes), for example as program code. In an embodiment, processor 52 implements instructions stored on a memory (not shown).

[0184] As part of the preparation process, electrical circuit system 16 may obtain additional preparation information from server system 8 and / or peripheral device 10 via computer network 12 using a communication interface (not illustrated) of the machine.

[0185] [General description of code]

[0186] refer to Fig. 9, the code 44 is formed by a plurality of circular cells 80 arranged on a surround 82. The cells 80 are dark in color (e.g., one of the following colors: black, dark blue, purple, dark green), and the surround 82 is a relatively light color (e.g., one of the following colors: white, light blue, yellow, light green), so that the contrast is sufficient for the image capture unit 46 to distinguish them.

[0187] The shape of the cell 80 is circular. As used herein, the term "shape" with respect to a cell may refer to an exact shape or an approximation of the actual shape, which may occur due to printing or other manufacturing precision variations.

[0188] In variant embodiments not illustrated: the unit is light-colored, while the surround is dark-colored; the unit has different shapes, including one or a combination of the following shapes: triangle, polygon, in particular quadrilateral such as square or parallelogram; other suitable shapes.

[0189] The cell 80 typically has a cell length of 50 μm to 200 μm. As used herein, the term "cell length" for the cell 80 may refer to a suitably defined distance of the cell 80, such as: for a circular shape, the diameter; for a square, the side length; for a polygon, the distance between opposite or adjacent vertices; for a triangle, the hypotenuse. The cell 80 is cut with an accuracy of about 1 μm.

[0190] The unit 80 is formed by printing (e.g., by means of an inkjet printer). As an example of printing, the ink may be a conventional printer ink, and the substrate may be: polyethylene terephthalate (PET); aluminum coated with lacquer (as present on Nespresso Classic capsules) or other suitable substrates.

[0191] In variant embodiments not illustrated: the cells are alternatively formed, including by embossing, imprinting or other suitable means, and are alternatively dimensioned, for example, to a cell length of 80 μm to 120 μm.

[0192] [Code Commons]

[0193] Further references Fig. 9 , the unit 80 is organized into a reference portion R (also referred to as reference portion) for locating and determining the orientation of the code 44 and a data portion D for storing preparation information.

[0194] The cells 80 of the code 44 arranged as the reference portion R include three reference cells 84. The reference cells 84 have a unique spatial arrangement in the code 44 to allow the reference portion R to be recognized by the electrical circuit system 16 in the digital image (e.g., having a stored relationship on its memory). The unique spatial arrangement includes the reference cells 84 arranged at three of the vertices of the virtual rectangle around the origin O at the center of the rectangle, with specific distances between the reference cells 84.

[0195] In variant embodiments not illustrated, the reference portion is alternatively implemented to include: different arrangements of reference cells, such as rectangles that are circles or other shapes; different numbers of reference cells, such as 4 or 5; and the reference cells may have a unique shape that can be identified from the shapes of other cells that form the code.

[0196] The arrangement of the reference cells 84 enables a single reference line r to be defined at a particular vector relative to the cells 84. The reference line r is virtual and is determined by the electrical circuit system 16 (eg, having a stored relationship on its memory).

[0197] In this particular example, the reference cells 84 define a first imaginary line (not shown) and a second imaginary line (not shown) using the right-hand rule, where: the thumb represents the first imaginary line intersecting the centers of two of the reference cells 84; the index finger represents the second imaginary line intersecting the centers of two of the reference cells, one of which is common to the first imaginary line; and the second finger enters the plane of the page of the code 44. The reference line r extends from the origin O and is parallel to the first imaginary line and orthogonal to the second imaginary line.

[0198] In variant embodiments not illustrated, the reference line may be alternatively defined: the reference line may comprise an actual line drawn on the code; the reference line may have an alternative geometrical arrangement relative to the reference cell.

[0199] The unit 80 of the code 44 arranged as the data portion D includes a data unit 86. The data unit 86 is arranged on an encoding line E intersecting with a reference line r. The encoding line E is virtual and is determined by the electrical circuit system 16, (e.g., the encoding line has a predetermined radius stored on its memory). The center of the circle of the encoding line E is arranged at the origin O of the reference portion R. Therefore, the reference line r intersects the encoding line E, and the tangent of the encoding line is orthogonal to the reference line r. There are two encoding lines E1, E2, each encoding line having a data unit 86.

[0200] In variant embodiments not illustrated: other numbers of encoding lines are implemented, including 3, 4 or 5; the encoding lines can have non-circular shapes, including rectangular or triangular; the encoding lines include actual lines drawn on the code.

[0201] The encoding line E includes one or more individual data portions, each of which includes a starting position 88 and a data unit 86, which is arranged along the encoding line E at a certain distance d from the starting position 88 as a variable encoding a parameter of the preparation information. The starting position 88 is virtually defined and can be determined by the electrical circuit system 16 (for example, the starting position can be stored in its memory).

[0202] For the first encoding line E1, the data portion includes two separate data portions: for the first separate data portion, the distance d can be any continuous distance from the starting position 88 at the reference line r to the first data unit 86 clockwise from the reference line r; for the second separate data portion, the distance d can be any continuous distance from the starting position 88 at the data unit 86 of the first separate data portion (therefore, the starting position is a variable) to the midpoint m between the subsequent two data units 86 in the clockwise direction.

[0203] For the second encoding line E2, the data portion includes a single data portion for which the distance d can be any one of a plurality of discrete distances, which are illustrated as discrete positions 90 from the starting position 88 at the reference line r, each position being associated with a value of a parameter. In the example, there are 10 discrete positions 90.

[0204] In variant embodiments not illustrated: the starting position may be arranged at any position on the coding line, including being spaced apart from a reference line; there may be multiple starting positions on the coding line, each starting position having an associated data unit; the starting position may be formed as a unit as part of the code rather than being virtually defined; the coding line may include a combination of parameters encoded by continuous distances and discrete positions; more than one or two data units on the coding line may define a parameter, which may be determined as an average of the positions; and the data portion may include any appropriate number of separate data portions.

[0205] The code 44 includes an outer perimeter 92 within which the cells 80 are arranged. The outer perimeter 92 is rectangular in shape and has a base size of 600 μm to 1600 μm, or about 1100 μm. The code 44 may be repeated so that multiple repetitions of the code 44 are arranged within a single digital image so that one or several best captured repetitions of the code may be selected for processing.

[0206] In alternative embodiments not illustrated: the outer perimeter may be alternatively shaped, including circular; the outer perimeter may have alternative sizes, including larger or smaller than the exemplary range.

[0207] In variant embodiments not illustrated, the data portion alternatively encodes the value of the parameter, including as alphanumeric symbols or other arrangements.

[0208] refer to Fig.10 , relative to Fig. 9 The code processing process for extracting the preparation information performed by the electrical circuit system 16 (or its code processing circuit system) includes:

[0209] Step 1 - Identify the location of the code unit

[0210] Box 100 : A digital image of the code 44 is obtained via the code reading system 118 .

[0211] Block 102 : Allocate pixels to dark areas in the digital image that may represent the unit 80 .

[0212] Box 104: If several cells are close to each other, it is determined that the cell 80 exists.

[0213] Block 106: For each determined cell, determine the center of the pixel grouping by, for example, a feature extraction rule to determine the coordinates of the center of the cell.

[0214] In unmodified embodiments not illustrated, alternative processing techniques for determining cells and coordinates may be implemented, including other techniques for locating the center of a cell or identifying a cell as present, for example, a magnification level may be implemented such that a single pixel is determined to be a cell, and the center of a cell may be determined to be the center of a pixel.

[0215] Step 2 - Locate the reference part of the code and the reading angle

[0216] refer to Fig.11 , relative to Fig. 9 The code for code 44 includes:

[0217] Block 108: Locate reference portion R by searching the coordinates of cells 80 of code 44 to identify a unique separation and geometric arrangement of reference cells 84. This may be accomplished by geometric rules including Pythagoras and trigonometry or other suitable rules. The separation and geometric arrangement may be stored on electrical circuit system 16 and accessed during the search.

[0218] Block 110: Using stored relationships to define the positions of origin O and reference line r for the located reference portion R. The arrangement of origin and reference line may be stored on the electrical circuitry 16 and mapped to the coordinates of the located reference portion.

[0219] Block 112: For each cell (except cells of the reference portion), determine which encoding line E the cell belongs to based on the distance from the origin O. The electrical circuit system 16 may store a radius range for each encoding line E and use geometric rules to determine the distance of each cell from the origin O and within which radius range it falls.

[0220] Box 114: For each cell (except the cells of the reference part), determine the angle α1, α2 relative to the reference line r. It should be noted that this angle represents the circumferential distance and can be used interchangeably. The angle can be calculated via the known geometric relationship between the coordinates of the reference line r and the virtual line extending from the origin O and passing through the associated cell.

[0221] Step 3 - Determine the values ​​of the parameters for the preparation information .

[0222] refer to Fig.11 , relative to Fig. 9 The processing of code 44 includes:

[0223] Block 116: Determine the encoding distance d for each individual data portion. This is accomplished by a set of rules for determining the encoding distance d stored by the electrical circuit system 16. This may include one or more of the following: the number of individual data portions on each encoding line; the starting position 88 of each data portion; whether a single cell or multiple cells represent a data unit 86; and other suitable relationships.

[0224] For example, refer to Fig. 9 , the rule for determining the encoding distance d of the encoding line E1 includes: two separate data parts; the starting position 88 of the first separate data part is at the intersection between the reference line r and the encoding line E1; the starting position 88 of the second separate data part is at the data unit 86 of the first separate data part; the data unit 86 of the first separate data part is represented as a single unit of the code 44; the data unit 86 of the second separate data part is represented as two units of the code 44.

[0225] For example, refer to Fig. 9 , the rules for determining the encoding distance d of the encoding line E2 include: a single individual data portion; the starting position 88 is at the intersection between the reference line r and the encoding line E2; the data unit 86 of the first individual data portion is represented as a single unit of the code 44.

[0226] Box 118 : Convert the encoded distance d for each data portion into a value of the parameter This is achieved by implementing a set of rules for converting distances of values ​​stored by the electrical circuit system 16 .

[0227] For example, for the encoded line E1: the first separate data portion can encode the water volume of the brewing process, where the distance d is any continuous value linearly related to the water volume; and the second separate data portion can encode the time of the brewing process, where the encoded distance d is any continuous value related to the time index.

[0228] For example, for encoding line E2: a single separate data portion may encode the water temperature of the brewing process, where the encoding distance d is a discrete value that changes incrementally by 5 degrees Celsius for each discrete position 90, and the rule specifies which 5 degree increment is closest to the determined encoding distance d.

[0229] In variant embodiments not illustrated, other rules may be implemented, including: other mathematical functions relating the encoding distance to parameter values; and whether the encoding distance is an average of distances of several separate data portions, and other suitable relationships.

[0230] [Closed component]

[0231] refer to Fig.12 , a first example of a closure member 56 including a code 44 is provided. The code 44 is integrally formed within a layer of the closure member 56, as will be discussed. The code 44 is formed integrally within a layer of the closure member 56, as will be discussed. Fig. 9 Arranged as discussed, and arranged in identical repetitions on the closing member 56, so that any one code is readable to obtain the preparation information. In variant embodiments not illustrated, other codes, such as bar codes, may be used, and the code may be repeated only once.

[0232] The code reading system 18 includes an illumination system 110 and a camera system 112. The illumination system 110 emits projected emission light 114 onto the closure member 56. The camera system 112 obtains a digital image of the code 44 from the reflected emission light 116 ( Fig. 9 An example is shown in ), as will be discussed.

[0233] The projected emission light 114 from the illumination system 110 is substantially at an infrared wavelength, such as a wavelength greater than 700nm or 800nm. The emission light may have any peak value between 800nm ​​and 1000nm, with a HWHM of ±100nm or 50nm or 25nm. In an example, the peak value is 850nm and the HWHM is ±30nm.

[0234] The camera system 112 is accordingly configured to obtain the digital image within the wavelength band. This can be achieved by the specific implementation of a filter that passes frequencies above 800nm ​​or 700nm or other suitable values ​​selected to remove any interfering wavelengths from the information bearing layer and the color layer, as will be discussed.

[0235] The closure member 56 is planar and extends in a longitudinal direction 100 and a transverse direction 102, with a depth direction 104 extending through the thickness from an outer surface 118 facing away from the storage portion 58 (at Figure 7 ) extends toward the precursor material stored in the storage portion (shown in Fig.12 Although the closure member 56 is shown as being planar, it may also be flexible and may therefore take different forms (e.g., Figure 7 shown).

[0236] [Protective layer]

[0237] The closure member 56 includes a protective layer 122 through which the code 44 can be read by the code reading system 18. The outer surface of the protective layer 122 is arranged as the outer surface 118. The protective layer 120 provides a barrier for food safety and also provides a protective cover for the code 44. The protective layer 110 is formed of regenerated cellulose. The thickness of the protective layer 110 is 22 microns. The protective layer has a transparency of at least 80% for the projected emission light 114 and the reflected emission light 116, which is selected to enable the code 44 to be read through the protective layer 122.

[0238] The protective layer 122 may be implemented with a matte finish, for example for diffuse light reflection. Examples include matte paint.

[0239] In alternative embodiments not shown, the protective layer is alternatively formed of other materials, including one or more of the following: sulpack white; translucent paper, including parchment or super calendered paper; translucent plastics, including PLA, PET, PE and PP; the protective layer can have an alternative thickness, such as 5 microns to 50 microns; and the protective layer can also be omitted.

[0240] [Absorption layer]

[0241] The code 44 includes an absorption layer 124 configured to absorb the projected emission light 114 and a reflective layer 126 configured to reflect the emission light 114 as reflected emission light 116. The code 44 is supported by a support layer 128 that is substantially transparent to the projected emission light 116. The reflective layer 126 is arranged to reflect the emission light before it is transmitted to the support layer 128, as will be discussed.

[0242] The absorption layer 124 is arranged between the reflection layer 126 and the outer surface 118 in the depth direction 104 so that the absorption layer 124 is closest to the outer surface 118 relative to the reflection layer 126 , and the reflection layer 126 is arranged between the support layer 128 and the outer surface 118 in the depth direction 104 .

[0243] The absorbent layer 124 includes units 80 (such as Fig. 9 4 ), these units together form the individual repeats of the code 44. The absorption layer 124 has a reflectivity of less than 10% and an absorption rate of at least 80% or 90%.

[0244] The unit 80 is formed of an ink having a carbon black color pigment, so the absorbent layer 124 absorbs all wavelengths of the visible spectrum, for example, 390nm to 700nm (as well as the wavelength of the projected emission light 114), so it is desirable to hide the absorbent layer 124, as will be discussed. The absorbent layer 124 has a thickness of 1 micron to 5 microns. As defined herein, the ink is selected to be biodegradable.

[0245] In alternative embodiments not illustrated, the absorbing layer is alternatively formed using non-carbon-based pigments which may include other relatively dark colors such as dark blue; dark purple; dark green; the units are alternatively formed from solid material sheets rather than ink.

[0246] The reflective layer 126 is continuous at a depth below the formation of cells 80 including the absorbent layer 124. With this arrangement, a portion of the projected emission light 114 that passes through the gaps between the cells 80 of the absorbent layer 124 is reflected by the reflective layer 126 and returns through the gaps in the absorbent layer 126 as reflected emission light 116.

[0247] [Reflection layer]

[0248] The reflective layer 126 is configured to diffusely reflect the projected emission light 114 as reflected emission light 116. The reflective layer 126 has a reflectivity of at least 70% for the emission light, and an absorptivity and / or transparency of less than 30% or 20% for the emission light.

[0249] The reflective layer 126 is formed of an ink containing a titanium dioxide (TiO2) based white pigment. The reflective layer 126 diffusely reflects all wavelengths of the visible spectrum, such as 390nm to 700nm (as well as the wavelength of the projected emission light 114), so it appears white when viewed by a user. The thickness of the reflective layer 126 is 1 micron to 5 microns. As defined herein, a biodegradable ink is selected.

[0250] The reflective layer 126 is connected to the support layer 128, such as via a connecting layer (which may be as discussed for the barrier layer) such that it abuts the support layer.

[0251] The reflective layer 126 is arranged to overlap the entire support layer 128 when viewed in a plane defined by the longitudinal direction 100 and the transverse direction 102. In this way, minimal / no projected light emission 114 passing through the support layer 128 is ensured.

[0252] In a variant embodiment not illustrated, the reflective layer is alternatively formed: using a non-titanium oxide based pigment, which may include other relatively lighter colors, such as white; light blue; yellow; light green; the reflective layer is alternatively formed of one or more solid material sheets having the same optical properties instead of ink; the reflective layer is not continuous, for example: the reflective layer is formed as discrete parts, which may be arranged in the depth direction below the absorption layer, or arranged at the same depth as the absorption layer but between units, or a combination of the arrangements, utilizing the reflective layer to reflect the emitted light between the gaps of the units passing through the absorption layer; and the reflective layer is arranged to form units of the code, and the absorber is arranged to absorb the emitted light between the units, in Fig.12 In the example shown in FIG. 5 , the reflective layer and the absorbing layer are interchanged.

[0253] [Support layer]

[0254] The support layer 128 is configured to provide primary structural support to the closure member 56. For example, at least 70%, 80%, or 90% of the tensile strength of the closure member 56 may be provided by the support layer 128.

[0255] The closure member 56 is selected to comply with penetration testing standards.

[0256] In an embodiment, the test criteria include that the closure member 56 is configured to be capable of being penetrated by one or more penetrators (such that it is fully penetrated in the depth direction to create a through hole) when subjected to a force greater than a threshold value.

[0257] The specifications of the penetrator are: the tip portion is angled from 70 degrees to 30 degrees, gradually tapering outward from a penetration point, which is located at the apex of the tip portion; the cross-section of the penetrator is circular (in the transverse and longitudinal planes); the tip portion has a full circle at the apex, and its radius is selected to correspond to the tip angle; the base of the penetrator (e.g., the distal end of the apex) has a diameter of 1.5 mm.

[0258] The threshold force per penetrator is 7 N to 10 N or 5 N to 15 N. Alternatively, the threshold is a combined force of 700 N (±20% or ±30%) applied to all penetrators, for example there may be 88 or 50 to 150 penetrators in total.

[0259] This penetration criterion ensures that the closure member 58 is penetrable by the machine 2 while being sufficiently impermeable to prevent accidental penetration, such as during handling. Since the support layer 128 is the primary structural support for the closure member 56, this criterion can be achieved by appropriately selecting the thickness of the support layer 128.

[0260] In this example, the support layer 128 comprises kraft paper 60 gsm having a thickness of about 96 microns. It has been found that such a thickness range provides adequate structural support while remaining conveniently penetrable by a machine 2. Paper produced by a kraft pulp making process (e.g., with low lignin and less cellulose degradation) provides relatively high elasticity and high tear resistance compared to paper produced by conventional pulping processes. The support layer 128 is selected to be biodegradable as defined herein.

[0261] Due to the requirements of permeability and biodegradability, the support layer 128 is transparent to at least 30% to 80% of the projected emission light 114 from the illumination system 110 .

[0262] In variant embodiments not illustrated: the support layer has an alternative thickness, for example 50 to 150 microns, or 75 to 125 microns, or 2 to 50 microns; the support layer is formed of other materials, for example aluminum-based and / or plastic-based materials, including PET12u / Alu30 / BOPP30; the support layer can be arranged as more than one layer, which together have the desired strength / permeability.

[0263] [Barrier layer]

[0264] See also Fig.12 and Fig.13 , the closure member 56 includes a barrier layer 130 that includes a laminate of the following layers: an inner cover layer 132; a tie layer 134; a sealing layer 136; a tie layer 138; and an outer cover layer 140.

[0265] The outer layer 132 and the inner layer 140 are configured to prevent water from penetrating into the sealing layer, and also prevent oil or similar substances from penetrating from the precursor material. The outer layer 132 and the inner layer 140 contain biodegradable aliphatic polyesters. Examples include one or more of the following: poly (butylene succinate) (PBS); poly butylene terephthalate-succinate (PBST); polyhydroxyalkanoate (PHA); polyhydroxybutyrate (PHB); poly (3-hydroxybutyric acid-co-3-hydroxyvaleric acid) (PHBH); poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV); polycaprolactone (PCL); polylactic acid (PLA); polyglycolic acid (PGA); polybutylene adipate-butylene terephthalate (PBAT). Other suitable ingredients may include: poly (alkylene dicarboxylates); polylactic acid-co-glycolic acid (PLGA); starch. An example is Ecovio, which includes PBAT and PLA.

[0266] The tie layers 134, 136 are configured to interconnect adjacent cover layers and sealing layers. The tie layers 134, 136 include biodegradable aliphatic polyesters, such as one or more of PBS, PBAT and / or PBST. The thickness is 3 to 5 micrometers (μm).

[0267] The sealing layer 136 is configured to provide a barrier to oxygen to increase the life of the container 6 by reducing the amount of oxygen that can be transmitted to the precursor material through the closure member 58. The sealing layer 136 comprises a vinyl alcohol polymer, including copolymers. The vinyl alcohol polymer includes: highly amorphous vinyl alcohol polymer (HAVOH), including copolymers, such as butanediol vinyl alcohol copolymer (BVOH). Examples are referred to as G-polymers.

[0268] In alternative embodiments not illustrated, alternative barrier layers may be implemented: more than one sealing layer may be present; only one of the outer or inner layer may be present; and the barrier layer may be omitted.

[0269] The thickness of barrier layer 120 is in the range of 20 pm to 125 pm. The thickness of connecting layers 124, 126 is micrometers (μm). The thickness of outer layer 122 and inner layer 130 is 20 pm to 50 pm. The thickness of sealing layer 126 is 1.5 pm to 10 pm. Such thickness is selected so that the closure member 56 can be penetrated by the aforementioned penetration test. Due to the thickness, barrier layer 130 is transparent to the projected emission light 114. Barrier layer 120 is selected to be biodegradable as defined herein.

[0270] The barrier layer 130 is connected to the support layer 128 via a tie layer (not shown), which is discussed above with respect to the tie layers 134 , 136 .

[0271] [Information Carrying Layer]

[0272] refer to Fig.12 and Fig.14 , the closure member 56 includes an information bearing layer 142. The information bearing layer 142 is configured to conceal the code 44 from a user when the user is viewing the closure member 56 while the container information is displayed to the user (compared to an embodiment without the information bearing layer 142). The effect is achieved by the effective positioning of the information bearing layer 142 relative to the absorptive layer 124, and the configuration of the reflective layer 126 and the information bearing layer 58, as will be discussed.

[0273] refer to Fig.14 The information bearing layer 142 is configured to provide the container information (as described above) as one or more discrete objects 148 visible to the user, for example, they are visible at a wavelength of 380nm to 750nm and are sized to be observable. The information bearing layer 142 is visible to the user through the protective layer 122 and the absorbing layer 124.

[0274] The information bearing layer 142 has relatively low absorptivity and reflectivity to the projected emission light 114 so that it does not substantially interfere with reading of the code 44 at the aforementioned wavelengths. In an embodiment, the information bearing layer has less than 20% absorptivity to the emission light and less than 30% reflectivity to the emission light.

[0275] To enhance visibility of the objects of the information bearing layer 142, the reflective layer 126 is configured to diffusely reflect all visible wavelengths, e.g., it is visible white (as well as those of the projected emission light 114). In this way, the reflective layer 126 appears as a white luminous background, on which the objects 148 of the information bearing layer 142 are superimposed.

[0276] The object 148 is configured to have a reference dimension L, which is typically the largest dimension of the object 148, for example, L is the side length of the rectangle or the diameter of the circle for a rectangular or circular object 148, or for an object of other shapes, the dimension is the rectangle or circle surrounding the object. The reference dimension L is greater than the reference dimension m of the code 44 discussed previously. In embodiments L>am, where a=2 or 3 or 5, the maximum value is 10 or 20. Fig. 9 In the example of code 44, m is 600 μm to 1600 μm, and L is 4 mm to 15 mm.

[0277] With such a size relationship, it has been found that users focus on the larger length proportions of the object 148 rather than the code 44 .

[0278] In a variant embodiment not illustrated: the object is formed of a plurality of different colors (for example a combination of cyan, magenta and yellow) to enable carrying more information and to enhance the concealment of the code.

[0279] Since both the code 44 and the object 148 exist in the visible spectrum, the code 44 may not be readable in visible wavelengths due to the presence of the information bearing layer 142 in the digital image. Such an arrangement may define the code 44 as hidden.

[0280] The information bearing layer 142 has a thickness of 1 to 5 microns. The information bearing layer 142 is formed of ink, and in particular of ink that does not contain carbon black so as not to interfere with the reading of the code 44 at the wavelength in question. The information bearing layer 142 is selected to be biodegradable as defined herein.

[0281] The information bearing layer 142 is completely overlapped by the reflective layer 126 and is arranged between the reflective layer 126 and the absorptive layer 124. In this way, the reflective layer 126 illuminates the entire information bearing layer 142.

[0282] Projected emission light 114 is projected through information bearing layer 142 in depth direction 104, and reflected emission light 116 is projected through information bearing layer 142 in the opposite depth direction 104. Visible wavelengths are projected in the same manner as the emission wavelengths, but wavelengths of the associated colors are absorbed by information bearing layer 142.

[0283] The information bearing layer 142 completely overlaps the absorbent layer 126. In this way, the code 44 is effectively hidden. The absorbent layer 126 is closest to the outer surface 118 relative to the information bearing layer 142.

[0284] In variant embodiments not illustrated: the information bearing layer is alternatively formed from, for example, a solid sheet of material rather than from ink; the information bearing layer is formed continuously on the reflective layer, for example, rather than as a discrete object; and the information bearing layer is omitted; the information bearing layer is alternatively arranged, including between the absorbing layer and the outer surface, or between units of the absorbing layer, or a combination of said arrangements.

[0285] [Color Layer]

[0286] refer to Fig.12 , the closure member 56 includes a color layer 146 arranged to impart a background color, such as brown, to the closure member 56. The color layer 146 is implemented in conjunction with the information bearing layer 142 to apply the background color to the associated object 144.

[0287] The color layer 146 is continuous and completely overlaps the reflective layer 128 and is arranged between the reflective layer 126 and the information bearing layer 142. In this way, the reflective layer 126 illuminates the entire color layer 146. The projected emission light 114 is projected through the information color layer 146 in the depth direction 104, and the reflected emission light 116 is projected through the color layer 146 in the opposite depth direction 104. The visible wavelengths are projected in the same manner as the emission wavelengths, but the wavelengths of the associated colors are absorbed by the color layer 146.

[0288] The color layer 146 completely overlaps the absorbent layer 126 and the information bearing layer 142. In this way, the code 44 is effectively hidden and the color is applied to the object 144.

[0289] The color layer has the same formation and transparency to emitted light and visible light as the information bearing layer 142, and will not be repeated for the sake of brevity.

[0290] In variant embodiments not illustrated: the color layer is alternatively formed from, for example, a solid sheet of material instead of ink; the color layer is formed at discrete locations on the reflective layer, for example at the locations of the object and / or the absorbing layer; the color layer is omitted; the color layer is alternatively arranged, including between the absorbing layer and the outer surface, or between units of the absorbing layer, or a combination of said arrangements.

[0291] [result]

[0292] refer to Fig.15 , shows a digital image of a laminate obtained by camera system 112, the laminate comprising Fig.12 All the layers of the closure member of the first example are shown, but without the reflective layer 126. The image shows acceptable resolution between cells 80 of the code 44.

[0293] refer to Fig.16 , shows a digital image of the same laminate when placed on a precursor material (not shown). It can be seen that the resolution between cells 80 of the code 44 is significantly reduced to a level that has been found to introduce reading errors.

[0294] refer to Fig.17 , shows that when arranged in a precursor material (which is Fig.13 and Fig.14 The same laminate, but with the addition of a reflective layer 126, Fig.12 A digital image of the closing member 56. It can be seen that Fig.14 Compared with digital images, even Fig.13 Compared to the digital image, the resolution between cells 80 is improved due to the inclusion of reflective layer 126.

[0295] [Precursor material for the absorbent layer]

[0296] refer to Fig.18 , a second example of a closure member 56 is provided, which includes the layers as the first example and associated variations, but the absorbing layer is omitted and the reflective layer 126 has alternatively been moved to the position of the absorbing layer, and the cells 80 of the code 44 are formed.

[0297] The reflective layer 126 reflects the projected emission light 114 as reflected emission light 116 to form a digital image of a code (not shown). Thus, the projected emission light 114 passes between cells formed by the reflective layer 126 and enters a subsequent layer.

[0298] If there is no reflective layer 126 to prevent the projected emission light 114 from being projected onto the support layer 128, the emission light is projected into the support layer 128 and passes through the support layer (and the barrier layer 130), so that the projected emission light 114 passes through the closure member 56. The projected emission light 114 is projected onto the storage portion 58 (see Figure 7 ) and is projected onto the precursor material 150.

[0299] Precursor material 150 serves as an absorbing layer for the first example, which provides a dark background. Cell 80 of code 44 appears as a light cell on the dark background because reflective layer 126 diffusely reflects the emitted light.

[0300] The precursor material 150 may absorb at least 60% of the incident projected emission light 114 from the illumination system 110. By implementing the precursor material to absorb a majority of the incident projected emission light 114, such as 50% or 70% or more, the precursor material 150 provides a uniform, relatively dark background in the image.

[0301] The precursor material 150 includes ground coffee. Ground coffee has been found to have a high absorptivity for the selected wavelengths of emitted light disclosed herein due to its high carbon black content (similar to the ink forming the absorber layer of the first example).

[0302] In alternative embodiments not illustrated: other precursor materials may be used, such as tea; for the first example, the reflective layer may be arranged at different positions in the closed member, including above, below or between the information bearing layer and the color layer, and the reflective layer may also be below the support layer.

[0303] [Specular reflector as support layer]

[0304] refer to Fig.19, a third example of a closure member 56 is provided, which includes layers as the first example and associated variations, but the support layer 128 is alternatively configured for specular reflection of incident projected emission light 114 from the illumination system 110.

[0305] As discussed for the first example, the code 44 includes an absorption layer 124 configured to absorb the emission light 114 and a reflection layer 126 configured to diffusely reflect a portion of the emission light 114. A portion of the emission light 114 that passes through the reflection layer 126 undergoes specular reflection.

[0306] As discussed for the first example, the reflective layer 126 reflects a majority of the emitted light 144 (e.g., the reflectivity of the emitted light is at least 70%) as reflected emitted light 116. Since the reflective layer 116 is diffusely reflective, the reflected emitted light includes diffuse light. The transparency of the emitted light can be less than 20% or 30% of the emitted light, with an optional minimum transparency of 5% or 10%.

[0307] Any remaining portion of the emitted light 144 (not absorbed by the reflective layer 126) is transmitted through the reflective layer 126 to the support layer 128 where it undergoes specular reflection, which can help illuminate the code 44 and / or provide the container with a surface finish that can be viewed through the code (e.g., the metallic finish of an aluminum support layer). The specular reflection can then be diffusely emitted from the reflective layer 126 (and / or transmitted through the reflective layer as a specular reflection).

[0308] With such an arrangement, the code 44 can be formed on a support layer that acts as a specular reflector, which would otherwise reflect the emitted light 114 in a specular manner and cause saturation of the code reader due to the high intensity of the reflected emitted light. For example, the support layer 128 can have a reflectivity of at least 70% or 90%, and a large portion of the emitted light (e.g., at least 70% or 90%) is specularly reflected. The support layer 128 can, for example, be implemented as aluminum or aluminum-based, including aluminum-based polymers, such as PET12u / Alu30 / BOPP30.

[0309] In the first, second and third examples and associated variations, the entire closure member 56 is optionally biodegradable. As used herein, the term "biodegradable" may refer to composability defined by EN 13432:2000 (including anaerobic conditions, decomposition, etc.) or EN 14046:2004 (aerobic conditions).

[0310] In various embodiments, the material of the closure member 56 optionally has a total thickness of 100 microns to 250 microns or 150 microns to 200 microns. It has been found that such a thickness range provides sufficient structural support while remaining conveniently penetrable by the penetrator of the machine 2.

[0311] In alternative embodiments not illustrated, the above-mentioned code and associated layers may be formed on other components of the container (eg, a storage portion), on other containers (eg, as a wall of a sac).

[0312] The protective layer 110, the absorptive layer 124, the reflective layer 126, the information bearing layer 142 and the color layer 146 are formed together as will be discussed and connected to the support layer 128 by a connecting layer (not shown) as described above.

[0313] [Method of forming a closing member]

[0314] refer to Fig.12 The process of forming the closing member 56 of the first example includes the following steps:

[0315] Step 1: Print the absorption layer 124 on the inner side of the protection layer 122 .

[0316] Step 2: The reflective layer 126, the information bearing layer 142 and the color layer 146 are then printed on the absorbent layer 124 and the protective layer 110 obtained from step 1 to form a printed laminate.

[0317] Step 3: The printed laminate from step 2 is bonded to a first side of the support layer 128 via a tie layer (which is configured as discussed for the barrier layer).

[0318] Step 4: Bonding barrier layer 130 to the second side of support layer 128 via a tie layer (configured as discussed for the barrier layer).

[0319] Step 5: Use a cutting tool to cut closure members 56 from the printed laminate of Step 4. Multiple closure members 56 can be formed from the same printed laminate from anywhere on the laminate because the code is repeated throughout the laminate.

[0320] In a variant embodiment: for step 1 and step 2, the printing of the absorption layer and the reflection layer can be completed simultaneously, for example, the reflection layer is formed in the gaps of the units of the absorption layer; the absorption layer, the reflection layer, the information bearing layer and the color layer are printed on the supporting layer code layer, and the laminate is bonded to the protective layer; steps 3 and 4 can be completed in any order, or simultaneously.

[0321] For the second example of a closure member, the layers are printed on a protective layer (or support layer) as in the first example, except that the absorbent layer is omitted. As in the first example, the laminate is then attached to the support layer.

[0322] For example, where the code is formed on other parts of the container, such as the body portion or the wall of the pouch, the layers may be printed directly onto the wall thereof (typically the support layer) and an optional protective layer bonded to the printed layer.

[0323] [How to read the code]

[0324] refer to Fig.10 With the associated foregoing description, for the first example of the closure member 58, block 100 (obtaining a digital image of the code) includes:

[0325] Step 1: Send the code from the code reading system 18 (see Fig.18 )'s projected emitted light 114 is projected through the protective layer 112 of the closing member 56 .

[0326] Step 2: For the projected emission light 114 , a portion of the emission light is absorbed by the absorption layer 124 (or in the second example of the closing member 58 , the precursor material 150 ), and a portion of the emission light is reflected by the reflection layer 126 as reflected emission light 114 .

[0327] Step 3: Capture a digital image of the code under the conditions of step 2.

[0328] The digital image from step 3 can then be processed to extract preparation information, such as for Fig.10 and Fig.11 The code handles the steps discussed.

[0329] The container 6 can then be used as for Figure 8 The process is carried out as discussed above with respect to the steps of, including the steps of perforating the closing member using a perforator of a beverage or food preparation machine and injecting a fluid into a storage portion of a container containing a precursor material.
