Description

Technical Field

[0001] The present invention is in the field of household and industrial appliances for producing liquid emulsions, such as liquid beverages, creams, sauces, etc., particularly of the type that can be consumed by humans as food or drink. In particular, the present invention relates to a filter beaker for producing liquid emulsions and related kits and devices for producing liquid emulsions using such a filter beaker. Background Art

[0002] A device for beverage production developed by the inventors is known from WO 2013 / 120813 A1. Figure 1 The device shown in is configured for producing beverages using a blending element such as a handheld blender and comprises a filter beaker 2 having at least a filtration area 3 and a pestle 6. As detailed in the cited document, the operation of the device described therein consists in inserting the filter beaker 2 into a suitable receiving beaker 1 and receiving ingredients to be used for producing a beverage (e.g., fruit or nuts) in the filter beaker 2. The blender can then be inserted into the filter beaker 2 and used to comminute the ingredients received in the filter beaker 2, thereby obtaining a liquid extract that is filtered through the filtration area 3 of the filter beaker 2 and collected in the receiving beaker 1.

[0003] After the action of the blending element is completed, the solid residue of the crushed ingredients remains in the filter beaker 1, which is then pressed using the pestle 6 in order to dry it and obtain as much liquid extract as possible from the original ingredients of the beverage. After the process is completed and the final beverage is obtained, the dry solid residue of the crushed and pressed ingredients remains in the filter beaker and must therefore be disposed of in order to prepare the device for use again.

[0004] The filtration area of ​​the device disclosed in WO 2013 / 120813 A1 comprises filter holes or a filter mesh with a given opening size, and the degree of filtration of the final beverage depends on the opening size used, which is fixed for a given device when the device is manufactured. Summary of the Invention

[0005] The inventors have made several technical improvements to the filter beaker and device disclosed in WO 2013 / 120813 A1, resulting in the present invention, which aims to increase the versatility and usability of the filter beaker and device while reducing costs both for the user and the manufacturer. This technical object is achieved by a filter beaker according to claim 1, a kit according to claim 13, and a device according to claim 15. Preferred embodiments of the invention are described in the dependent claims.

[0006] A first aspect of the present invention relates to a filter beaker for producing a liquid emulsion, specifically by the action of a blending device. The filter beaker can be used as a household appliance, as an industrial tool in the food industry, and / or as an appliance for food / beverage preparation in a hotel business. "Liquid emulsion" can specifically refer to a liquid mixture or blend of at least one solid ingredient and at least one liquid ingredient in this article, such as a plant beverage made from seeds, beans, cereals and / or nuts (solid ingredients) and water (liquid ingredients) or a broth made from meat and / or fish (solid ingredients) and water (liquid ingredients), but can also refer to a juice or extract made from fruit or other liquid-containing foods, such as in the case of fruit, using its pulp (solid ingredients) and the water (liquid ingredients) contained in fruit or milk. Although the term "liquid" emulsion is used herein, it can also refer to a viscous emulsion, such as cream and / or thick sauces, such as mayonnaise, which can be more or less "liquid" according to their viscosity. A liquid emulsion can, for example, be an ultrafine emulsion, a pasty emulsion, or even a dough-like emulsion.

[0007] The filter beaker comprises a body with a tubular geometry, which can be specifically configured to receive a blending device for producing a liquid emulsion therein, such as a hand-held mixer, which may or may not be an electric device. "Tubular geometry" in this article can specifically refer to a substantially hollow geometry formed by one or more side walls that surround an interior space and separate it laterally from an exterior space. The hollow interior volume of the tubular body can specifically be free of any obstructions. One or more side walls can extend longitudinally (axially) between a first longitudinal end (top) and a second longitudinal end (bottom) of the body, which can specifically be an open longitudinal end that connects the interior space surrounded by the one or more side walls to the outside of the body.

[0008] The filter beaker can, for example, have a substantially cylindrical geometry with a substantially circular cross-section, so that manufacturing the body can, for example, involve cutting a piece of tubular material, such as metal or plastic, at two different axial cutting locations, wherein the distance between the two cutting locations determines the longitudinal extension of the body, and so that a plurality of bodies can be obtained from the initial piece of tubular material. However, other geometries besides cylindrical and other cross-sections besides circular are also possible in the filter beaker according to the invention, such as oval, square, or polygonal.

[0009] In some embodiments, the cross-section of the body can be constant throughout its entire longitudinal (axial) extension. In other embodiments, the cross-section of the body can vary over its longitudinal extension. For example, the body can have a substantially circular cross-section, and its diameter remains constant over at least a portion of the longitudinal extension of the body, or specifically increases or decreases continuously from one longitudinal end toward the other longitudinal end. In an exemplary embodiment, the body can have a substantially circular cross-section of a first diameter at its first longitudinal end, and this first diameter continuously decreases to a second diameter smaller than the first diameter over a portion of the longitudinal extension of the body toward its second longitudinal end, thereby forming a widened portion of the body at the first longitudinal end, so that the body can have a frustoconical geometry over at least a portion of its longitudinal (axial) extension. The widened portion of the body at its first longitudinal end defines a larger cross-section through which the ingredients can be introduced into the filter beaker, and thus can simplify the task of introducing the ingredients into the filter beaker without the risk of lacking the cross-section of the filter beaker.

[0010] The body can be configured to receive therein a blending device for producing a liquid emulsion. "Blending device" herein may refer to a device suitable for blending, crushing, squeezing, and / or mixing at least one solid component with preferably at least one liquid component, possibly by the action of rotating blades. The blending device can be, for example, or include, a conventional household hand-held mixer, but can also be or include a non-electrical device, such as a mechanical hand-operated device.

[0011] The geometric shape of the main body can be such that it allows the blending device to be inserted into the inner space of the main body so that the blending device can be used to produce liquid emulsions as will be explained below. The main body specifically can have an internal diameter of 5cm to 40cm, preferably 6cm to 20cm, more preferably 7cm to 15cm correspondingly at its one open longitudinal end, and the blending device can be introduced into the filter beaker by the open longitudinal end, and cross a part of the longitudinal (axial) extension length of the main body from the open longitudinal end. The internal diameter with the above-mentioned range ensures that the filter beaker is suitable for receiving most blending devices available on the market, and most blending devices available on the market usually have a maximum diameter of 6cm to 6.5cm in the case of a domestic blending device and in the case of the professional blending device used in the hotel business (such as restaurants) and the food production industry at the mixing head including a blade.

[0012] The filter beaker further comprises a filter body. The filter body has a geometry that matches the tubular geometry of the main body, at least at its connecting portion (and possibly over at least a portion or the entire longitudinal extension of the filter body). The filter body can have a geometry that matches the tubular geometry of the main body, in particular a tubular or disc-shaped geometry, at its connecting portion or over its entire longitudinal extension.

[0013] The filter body is removably attached to the main body via a connecting portion of the filter body. The filter body has, at least at the connecting portion, a geometry that matches or corresponds to the geometry of the main body, in particular for the purpose of being attachable to the main body.

[0014] As used herein, “a geometry matching the tubular geometry of the body” may mean that the filter body may have and / or cover a cross-section (particularly an inner cross-section) that is the same or at least similar to the cross-section (particularly an inner cross-section) of the body when the filter body is attached to the body.

[0015] In some embodiments, the entire cross-section of the filter body can match the cross-section of the main body, i.e., the main body and the filter body can have geometries that match both internally and externally, such that the filter body can form a longitudinal (axial) extension of the main body at least at the connection portion, but can also form a longitudinal (axial) extension of the main body over a longer part of the longitudinal extension of the filter body, for example over the entire longitudinal extension of the filter body. For example, the filter body can have a tubular geometry, and the tubular peripheral contour and / or cross-section of the filter body can match the tubular peripheral contour and / or cross-section of the main body, in particular at the connection portion by which the filter body and the main body can be attached to each other, said connection portion can in particular correspond to a longitudinal end of the filter body.

[0016] However, as used herein, "a geometry that matches the tubular geometry of the body" may also mean that the filter body can be integrated and / or received within the tubular geometry of the body. For example, the filter body can be disc-shaped and can be configured to be received within and / or connected to the tubular body, wherein the perimeter of the filter body corresponds to the perimeter of the body.

[0017] However, the fact that the filter body has a geometry that matches the tubular geometry of the main body at least at the connecting portion does not necessarily mean that the geometry of the main body and the geometry of the filter body have to be identical.

[0018] In embodiments where the filter body has a tubular geometry, when the filter body is attached to the main body, one or more side walls of the filter body can smoothly connect to one or more side walls of the main body at the connection portion, such that, for example, the geometry of the filter beaker, as viewed from the outside, can be substantially free of any surface irregularities or longitudinal steps. For example, if the main body has a circular cross-section, then the geometry of the filter body "matching the tubular geometry of the main body" can mean that, at least at the connection portion where the filter body can be attached to the main body, the filter body can also have a circular cross-section having a diameter corresponding to the diameter of the circular cross-section of the main body at its corresponding longitudinal end. The filter body and the main body can have the same cross-section throughout their respective longitudinal (axial) extensions. In other related embodiments, the filter body can, for example, have a substantially constant cross-section throughout its entire longitudinal extension, while the main body can have a variable cross-section over its longitudinal extension or a portion thereof, specifically, the cross-section increasing in size with increasing distance from the filter body over at least a portion of the longitudinal extension of the main body.

[0019] When the filter body is attached to the main body, the filter body can be arranged next to and below the main body and / or arranged in the main body so that the blending device received in the filter beaker can be received in whole or in part in the main body. For example, if the filter body has a tubular geometry, the upper portion of the blending device can be received in the main body, and the lower portion of the blending device can be received in the filter body, and the lower portion can specifically include a rotating blade. The connecting portion can correspond to or include the open longitudinal end (top) of the tubular filter body. When attached to the main body, the blending device can be, for example, received in the filter beaker by extending over the entire longitudinal extension length of the main body and by partially or completely extending into the filter body.

[0020] However, some embodiments may contemplate the operation of the blending device being received solely within the body of the filter beaker. For example, if the filter body has a disc-shaped geometry, the blending device received within the filter beaker may be completely received within the body. The connecting portion may then correspond to or include the perimeter of the disc-shaped filter body, by which the filter body can be attached to the tubular body.

[0021] As used herein, "removably attached" may mean that the filter body can be mechanically connected to the main body to form a stable mechanical connection capable of withstanding the effects of a blending device received within a filter beaker, particularly where movement of the filter body and main body relative to each other is not required, but can be selectively removed when desired, particularly without affecting the integrity and functionality of the main body or filter beaker. In other words, the filter body and main body can be repeatedly attached and detached from each other multiple times while maintaining full functionality for the purposes of the present invention.

[0022] When the filter body and the main body are attached to each other, the mechanical connection between the filter body and the main body can be specifically fluid-tight. In some embodiments, the filter beaker can include a sealing element, such as a sealing ring, which can be disposed between the filter body and the main body, particularly at the connection portion of the filter body, when the filter body and the main body are attached to each other. The sealing element can ensure that the mechanical connection between the filter body and the main body is fluid-tight when attached to each other, even during operation of the blending device received in the filter beaker, thereby improving its functionality and reliability.

[0023] According to some embodiments, the filter body can be removably attached to the main body by means of a releasable coupling mechanism, and the releasable coupling mechanism is preferably a threaded mechanism or a clamping mechanism. For example, the main body can include a threaded concave profile to be attached to the filter body at its longitudinal end, and the filter body can include a corresponding threaded convex profile that matches the threaded concave profile of the main body at its open longitudinal end (e.g., top). It is also possible to foresee the opposite configuration, i.e., the threaded concave profile in the filter body and the threaded convex profile in the main body. It is also possible to foresee other types of mechanisms such as clamping mechanisms, snap mechanisms or bayonet mechanisms as releasable coupling mechanisms according to relevant embodiments. The releasable coupling mechanism allows the filter body to be disassembled from the main body in a simple manner while ensuring that the filter body and the main body are mechanically stable, reliable and fluid-tightly connected when the filter body and the main body are attached to each other.

[0024] The filter body is or includes a base covering the cross-section of the filter beaker. Although the main body has open ends at both of its longitudinal ends, the filter body (especially if configured with a tubular geometry) can have an open longitudinal (axial) end, which includes (or is) a connecting portion and the filter body can be attached to the main body at this open longitudinal (axial) end, but can be closed at least in cross section by the base. In some embodiments, the base can be arranged at a longitudinal (axial) position that can correspond to the connecting portion or be longitudinally (axially) spaced apart from the connecting portion. In some embodiments, the base can correspond to a closed longitudinal end of the tubular filter body, and at least one side wall of the tubular filter body can terminate at this closed longitudinal end.

[0025] Thus, the base of the cross-section of the filter body that covers the filter beaker can be disposed at one longitudinal (axial) end of the tubular filter body, but this need not be the case. In some embodiments, the base of the cross-section of the filter body that covers the filter beaker can be disposed longitudinally (axially) between the two longitudinal (axial) ends of the tubular filter body. For example, at least one sidewall of the tubular filter body can extend longitudinally (axially) from the connection portion of the filter body (which can be formed at one open longitudinal end of the tubular filter body) to the longitudinal (axial) position of the base of the filter body, and may extend beyond the longitudinal (axial) position of the base of the filter body.

[0026] In some embodiments, the filter body can be a base that covers the cross-section of the filter beaker. The filter body can, for example, have a disc-shaped geometry configured to cover the cross-section of the main body when the filter body (base) is attached to the main body, for example, using a clamping mechanism. In such embodiments, the filter body (base) can be attachable to the main body at the bottom axial end of the main body and / or arranged between the two axial ends of the main body at an intermediate axial position within the main body.

[0027] The base of the filter body may completely cover the cross-section of the filter body, thereby geometrically closing the interior space of the filter beaker from below when the main body and the filter body are attached to each other. Thus, the interior space of the filter beaker can be laterally closed by the side walls of the main body, and possibly also by longitudinal portions of the side walls of the filter body (for example, if the filter body has a tubular geometry), and can be surrounded from below by the base, while remaining open from above at the longitudinal end of the main body remote from the filter body. It is worth noting that the fact that the base of the filter body can geometrically close the interior space of the filter beaker from below does not necessarily mean that the base of the filter body fluid-tightly closes the interior space of the filter beaker from below. As will be explained later, in some embodiments of the present invention, although a geometric closure of the interior space of the filter beaker is provided from below, the base of the filter body can be configured to allow liquid and / or (some) solids to pass through.

[0028] According to the present invention, the filter beaker (specifically, the filter body) includes at least one filtration zone for filtering and emulsifying the liquid emulsion produced using the filter beaker, specifically through the action of a blending device received therein. It is noteworthy that the "liquid emulsion being produced" refers to the liquid emulsion that is in the process of being produced using the filter beaker of the present invention and may be different from the final liquid emulsion. As the mixing process progresses, the properties of the "liquid emulsion being produced," such as uniformity, clarity, or viscosity, may evolve due to the action of the blending device received in the filter beaker until the "liquid emulsion being produced" becomes a final liquid emulsion suitable for human consumption and / or having desired properties.

[0029] According to some embodiments, at least one filter area may include, for example, a filter screen, a filter bag and / or a plurality of filter holes. Specifically, at least one filter area may include at least one filter screen that covers one or more windows in the filter body and / or the main body and / or a plurality of filter openings formed in the filter body and / or the main body. In the case of a filter screen, the filter screen may be formed by interwoven mesh wires, for example, made of fabric and / or metal (such as steel or iron), and the filter size may be defined by the mesh size (i.e., the distance between adjacent mesh wires). The filter bag may be arranged to cover one or more openings in the filter body, thereby forming at least one filter area. In the case of filter holes, the filter holes may, for example, have a circular shape, and the filter size may correspond to the diameter of each filter hole or at least to the largest filter hole. The filter holes may, for example, be formed directly on the surface of the filter body and / or the main body, for example, configured as a micro-perforated plastic and / or metal surface of the filter body and / or the main body. "Filter size" in this article may refer to the maximum pore size or diameter of the filter hole and / or filter screen. In other words, a "filtration size" X may mean that particles up to a size of X can move through the at least one filtration region, while particles larger than a size of X are not allowed to pass through the at least one filtration region.

[0030] Due to the presence of at least one filtration zone, the blending device can have a twofold effect:

[0031] As a first effect, at least one of the filtration zones has an emulsifying effect: driven by a blending device (e.g. a hand mixer) received in the filter beaker, the ingredients being mixed are centrifuged through the filtration zone with a turbulent flow into and out of the filter beaker, which results in the formation of a homogeneous and smooth final liquid emulsion in which the ingredients used are mixed, in particular homogeneously mixed.

[0032] As a secondary effect, the at least one filter area performs a filtering function: particles or residues of solid components used to produce the liquid emulsion, which are received in the filter beaker and have a size larger than the filter size of the at least one filter area, are retained by the at least one filter area in the filter beaker and are thus prevented from being present in the final liquid emulsion that can be collected outside the filter beaker, in particular in a container in which the filter beaker can be received (which can be a specially designed container or a conventional container such as a glass or a jar). However, liquid and particles or residues of the solid components having a size smaller than or up to the filter size can pass through the filter area and thus be present in the final liquid emulsion.

[0033] In a preferred embodiment of the present invention, the filtration size of at least one filtration zone can be 0.1 mm to 5 mm, preferably 0.1 mm to 3 mm, and more preferably 0.1 mm to 0.8 mm. A filtration size within the above range optimizes the combined effect of the two effects of the at least one filtration zone. The filtration size can be adapted to the specific application depending on the ingredients to be emulsified. Specifically, at least one filtration zone can have a filtration size of 0.1 mm to 0.25 mm, for example 0.15 mm, for producing a liquid emulsion from water and seeds such as soybeans or tiger peas. A filtration size of 0.25 mm to 0.45 mm, for example 0.3 mm, can be used to produce a liquid emulsion from water and grains such as rice or oats. A filtration size of 0.45 mm to 0.8 mm, for example 0.5 mm, can be used to produce a liquid emulsion from water and nuts such as peanuts, hazelnuts, or cashews. A filtration size of 0.6 mm to 1.5 mm, for example 0.8 mm, can be used to produce a liquid emulsion from fruits and / or vegetables, optionally with milk and / or water. A filter size of 1 mm to 5 mm, eg 2 mm or 3 mm, can be used for producing liquid emulsions from meat, vegetables and / or fish and water, eg for producing bouillons, creams, soups, purees and / or sauces.

[0034] Unlike the filter beaker previously developed by the present inventors and described in WO 2013 / 120813 A1 as a one-piece filter beaker, the filter beaker according to the present invention comprises two components: a main body and a filter body. These components can be securely and stably attached to each other, but can also be selectively detached from each other. This offers several advantages for both operation and manufacture of the device.

[0035] On the user's side, the ability to detach the filter body from the main body can greatly simplify the task of handling solid residues remaining in the filter beaker after being used to obtain a liquid emulsion (and possibly after being pressed using a pestle, etc. and / or the blending device itself). With the closed-end, single-piece filter beaker disclosed in WO 2013 / 120813 A1, due to the filter beaker having an irremovable closed bottom end, extracting solid residues from the interior of the filter beaker may require using a spoon, etc., rotating the filter beaker up and down, and / or violently banging the filter beaker against a hard substrate. In contrast, the filter beaker according to the present invention allows solid residues to be easily removed from the interior of the filter beaker by detaching the filter body from the main body, thereby allowing them to be handled by simply pushing the solid residues within the main body out of the main body, for example, using a spoon, pestle, or piston and / or possibly the blending device itself. Any additional solid residues present in or on the filter body can also be easily handled, particularly in embodiments where the longitudinal extension of the main body can be greater than the longitudinal extension of the filter body. The inventors have found that, due to the action of the blending device, most of the solid residues tend to accumulate on the side walls of the main body and / or filter body and can therefore be easily removed from the interior of the filter beaker once the base of the filter beaker is removed, i.e. once the filter body is detached from the main body.

[0036] Furthermore, since the filtration size is determined by at least one filtration area, which can be formed in the filter body, and the filter body can be detached from the main body, it is possible for the user of the filter beaker of the present invention to use a main body with different versions or models of filter bodies, for example, depending on the requirements of the liquid emulsion to be produced. For example, the user can choose from filter bodies with different filtration sizes, making it easy and quick to adapt the filter beaker to a specific application. Thus, the filter beaker of the present invention can be configured for use with a single main body and a set of replaceable filter bodies.

[0037] On the manufacturing side, the structural independence of the filter body and main body of the filter beaker from one another allows for their production lines to be separated. This is advantageous because manufacturing a filter body, which may specifically include at least one filtration zone, can be more complex and expensive than manufacturing a main body, which may have a relatively simple geometry and structure and require less involved industrial equipment and / or machinery. Therefore, due to the structural independence of the main body and filter body, the filter beaker according to the present invention can be manufactured with increased efficiency, reduced complexity, and reduced costs, as the more complex parts can be manufactured independently of the less complex parts. Since the same main body can be used in combination with different types of filter bodies, manufacturers of the filter beakers according to the present invention can benefit from economies of scale in the production of the main body.

[0038] In a preferred embodiment of the invention, at least one filtration area may be arranged at the base of the filter body and / or at least one side wall of the filter beaker, in particular the filter body. The main body may preferably be free of any filtration area, and the entirety of the at least one filtration area of ​​the filter beaker may be arranged at the base of the filter body and / or at least one side wall thereof. In some embodiments, the at least one filtration area may be entirely arranged at the base of the filter body, and at least one side wall of the filter body may not be free of any filtration area. In embodiments in which all or some of the at least one filtration area is arranged at the base of the filter body, a downward flow driven by the rotational movement of the blending device received in the filter beaker, in particular by rotating its blades, may be used to enhance the emulsification effect, which may also be supported by filtration areas arranged on the filter body and / or at least one side wall of the main body.

[0039] However, in some embodiments, at least one sidewall of the main body, particularly its bottom portion and / or a portion thereof adjacent to the filter body and / or base, may include one or more additional filter areas, preferably configured and constructed similarly to the one or more filter areas of the filter body. The one or more additional filter areas may, for example, include a filter mesh, a filter bag, and / or a plurality of filter holes. In embodiments in which the filter body (particularly at the base and / or at least one sidewall of the filter body) includes one or more filter areas, and the main body (particularly at least one sidewall of the main body, preferably at its bottom portion and / or in a portion thereof adjacent to the filter body) includes at least one or more additional filter areas, the filter size of the one or more filter areas included in the filter body may be different (preferably greater) than the filter size of the one or more additional filter areas included in the main body. Therefore, the filter size of the filter body may be decisive for the effective filter size of the filter beaker, as it defines the maximum filter size and may be positioned closest to the blades of the blending device used to produce the liquid emulsion. The additional filter area in the main body may facilitate better flow conditions for the one or more liquid components used to produce the liquid emulsion from the interior to the exterior of the filter beaker, and vice versa.

[0040] According to a preferred embodiment of the present invention, the longitudinal (axial) extension of the main body can correspond to at least 1.2 times, preferably at least 1.5 times, and more preferably at least 2 times the longitudinal extension of the filter body. This particularly applies to filter bodies having a tubular geometry and / or embodiments in which the filter body is arranged below and adjacent to the main body (in the axial or longitudinal direction) when the filter body is attached to the main body. Therefore, the longitudinal (axial) extension of the main body can be at least 20%, preferably at least 50%, and more preferably at least 100% greater than the longitudinal (axial) extension of the filter body. In some embodiments, the main body can have an even greater longitudinal (axial) extension than the filter body, for example at least 5 or 10 times the longitudinal extension of the filter body, for example when the filter body is the base of the cross-section covering the filter beaker. The blending, crushing, squeezing and / or mixing effect of the blending device received in the filter beaker can mainly originate from the bottom end of the blending device, at which, for example, rotating blades can be arranged. Therefore, it may be sufficient, in particular according to the aforementioned ratio range, for the filter body, including the at least one filter area, to have a reduced longitudinal extension compared to the main body, since a large portion of the blending, comminuting, squeezing, and / or mixing effect of the blending device can be concentrated within the filter body within this reduced longitudinal extension. A main body with a greater longitudinal extension means that a larger portion of the filter beaker according to the present invention has a simple structure and geometry and is therefore easier to manufacture at reduced cost with less industrial equipment and / or machinery involved, whereby the overall production cost and manufacturing complexity of the filter beaker according to the present invention can be significantly reduced.

[0041] In some embodiments, the main body may include or be made of one or more first materials, and the filter body may include or be made of one or more second materials, wherein the one or more second materials may be different from the one or more first materials. Due to the structural independence of the main body and the filter body, the possibility of manufacturing the main body and the filter body separately from each other makes it possible to use different materials for the main body and the filter body, respectively. For example, the first material may be or include plastic and metal, and the second material may be metal, such as steel, specifically stainless steel. The opposite situation is also possible, that is, the first material may be metal, such as steel, specifically stainless steel, and the second material may be plastic. However, in some embodiments, the first material and the second material may be or include the same material, for example plastic or metal, such as steel, specifically stainless steel.

[0042] According to a preferred embodiment of the present invention, the filter beaker may further include one or more upright portions configured to support the filter beaker on a base plate when the filter beaker is placed upright on the base plate. The base plate may specifically correspond to the bottom of a container in which the filter beaker can be received to produce a liquid emulsion, which can then accumulate in the container. The one or more upright portions may extend in the longitudinal (axial) direction of the filter beaker, maintaining a gap between the base plate and the filter body and / or between the base plate and the base when the filter beaker is placed upright on the base plate. Thus, due to the one or more upright portions, when the filter beaker is placed upright on the bottom of the container, the base and / or filter body, particularly its bottom longitudinal (axial) end, does not directly contact the bottom of the container. Instead, the one or more upright portions create an intermediate gap between the bottom of the container and the filter body and / or base. Thus, the one or more upright portions serve as upright legs for the filter beaker, thereby maintaining the filter body and / or base of the filter beaker elevated relative to the bottom of the container in which the filter beaker is placed. This gap or spacing between the filter body and / or base and the bottom (base plate) of the container allows the turbulent flow driven by the blending device received in the filter beaker to be directed axially downwards towards the bottom of the container through one or more filtration areas arranged on the base of the filter body within the gap or spacing. Thus, an improved emulsification effect can be achieved and the usability of the filter beaker can be improved.

[0043] According to a preferred embodiment of the present invention, one or more upright portions may correspond to portions of at least one side wall of the filter beaker (i.e., the main body and / or the filter body), and one or more openings may be formed in at least one side wall of the filter beaker, i.e., at least one side wall of the main body and / or at least one side wall of the filter body. The one or more openings may extend upward from the bottom end of the filter beaker, i.e., from the bottom end of the main body and / or from the bottom end of the filter body in the longitudinal direction of the filter body. The opening may extend upward from the bottom end of the filter beaker to a height H. Thus, the upright portion is formed between the one or more openings.

[0044] Alternatively, the one or more openings may all have the same extent in a circumferential direction perpendicular to the longitudinal direction (e.g., may all cover the same angle in a cylindrical coordinate system). More preferably, the one or more openings and the upright portion may all have the same extent in a circumferential direction perpendicular to the longitudinal direction. In some embodiments, the height H may correspond to the distance in the longitudinal direction between the bottom end of the filter body and the longitudinal position of the base of the filter body, such that the upright portion of at least one side wall of the filter body may extend longitudinally beyond the base of the filter body, and the one or more openings may extend longitudinally from the bottom end of the filter body to the base.

[0045] The spatial region enclosed by the upright portion of at least one side wall of the filter body is in fluid communication with the exterior thereof via one or more openings. Thus, the base of the filter body can longitudinally separate the interior of the filter beaker from the aforementioned spatial region enclosed by the upright portion of at least one side wall of the filter body.

[0046] As previously explained, when the filter beaker is received in a container for producing a liquid emulsion to be collected in the container, the upright portion can be used to allow the filter beaker to rest on the bottom of the container, such that the upright portion rests against the bottom of the container and acts as a "standing leg" for the filter beaker. Due to the upright portion, when the filter beaker rests on the bottom of the container, a vertical gap remains between the base of the filter portion and the bottom of the container receiving the filter beaker. The gap can have a longitudinal extension length equal to or greater than the height H. This gap can allow the turbulent flow driven by the blending device received in the filter beaker to be guided through one or more filtration areas arranged on the base of the filter body, first axially downward from the interior space of the filter beaker toward the bottom of the container into the spatial area enclosed by the upright portion, and then radially outward through the one or more openings. As a result, an improved emulsification effect can be achieved and the usability of the filter beaker can be improved.

[0047] The one or more openings of the filter body may have a circular, square, and / or polygonal shape. The one or more openings may be formed as longitudinal recesses or notches in at least one side wall of the filter body, arranged between adjacent upright portions. For example, the side wall of a substantially cylindrical filter body may have a sawtooth structure, wherein each of the one or more openings may be formed as a quadrilateral perforation or recessed portion of an upright portion and may be evenly spaced such that each of the one or more openings is arranged between two adjacent non-recessed portions (merlons) corresponding to the upright portions of the side wall of the filter body.

[0048] In some preferred embodiments, particularly when the filter body has a tubular geometry, the base of the filter body can be or include a filter element, which includes one or more of the at least one filter area. The filter element can be removably attached to the rest of the filter body. The one or more filter areas arranged in the filter element can be configured as a filter screen and / or a plurality of filter holes. The filter element can, for example, be or include a filter disc, which includes a disc-shaped filter screen.

[0049] The filter element can be removably attached to at least one side wall of the filter body by means of corresponding fastening means, which can, for example, comprise a clamping means, a snap-fit ​​means, etc., and can comprise one or more sealing elements, such as sealing rings, for achieving fluid-tightness in the connection between the filter element and the rest of the filter body. In particular, the sealing elements arranged between the filter element and the rest of the filter body and / or between the filter element and the main body can ensure that the connection between the filter element and the filter body and / or the main body is fluid-tight, even when the blending device received in the filter beaker is in an active state, so that no liquid can leak through the connection and can instead flow through.

[0050] The filter body may include a retaining portion for retaining the filter element. For example, the filter body may include a recess formed as one or more radial protrusions that extend radially over a portion of the radial extension (thickness) of the filter body, thereby forming a stepped profile and / or retaining points on which a filter element, such as a filter disc, may be arranged and secured in place by corresponding fastening means. In some embodiments, the filter element may include at least one of the one or more filter areas, while the remainder of the body and / or filter body (except for the filter element) may be free of any filter area.

[0051] The configuration of the filter beaker with the filter element described in this embodiment further enhances the aforementioned advantages achieved by the filter beaker of the present invention. Flexibility of use is enhanced, as the filter size of the filter beaker can be selectively adapted by replacing only the filter element, without having to replace the remaining components of the filter beaker. This allows for filter elements with different filter sizes. Furthermore, the complexity of manufacturing the at least one filter area can be concentrated in the manufacture of the filter element, thereby further simplifying the manufacture of the main body and, if applicable, the remaining components of the filter body.

[0052] According to some embodiments, the filter beaker may include one or more radial protrusions configured to act as a stopper, thereby preventing the piston or pestle from pressing directly against the base when inserted into the filter beaker to press the solid components received therein. The one or more radial protrusions may specifically protrude radially inwardly from at least one sidewall of the body or the filter beaker.

[0053] In some preferred embodiments, the filter beaker (particularly the main body) may include a handle for holding the filter beaker.

[0054] A second aspect of the invention relates to a kit for producing a liquid emulsion, the kit comprising a filter beaker according to any embodiment of the first aspect of the invention, i.e. a filter beaker having a main body and at least one filter body according to any of the previously discussed embodiments. The kit may comprise a plurality of different filter bodies, each filter body comprising at least one filter area and being removably attached to the main body. Additionally or alternatively, the kit may comprise a plurality of different bases of the filter body configured as different filter elements, each base comprising at least one filter area and being removably attached to the remainder of (one) filter body of the filter beaker. The filter sizes of different filter bodies in the plurality of filter bodies and / or different filter elements in the plurality of filter elements may be different from each other. Thus, the user of the kit according to the invention can always use the same main body and select, depending on the desired use, the (entire) filter body and / or the base of the filter body having a filter area with a selected filter size.

[0055] A third aspect of the present invention relates to a device for producing a liquid emulsion, the device comprising a filter beaker according to any embodiment of the first aspect of the present invention and / or a filter kit according to any embodiment of the second aspect of the present invention.

[0056] The device according to the third aspect of the present invention may further comprise a piston configured to be received in a filter beaker and to at least partially, preferably completely, cover the internal cross-section of the filter beaker. Specifically, the piston may be a handheld piston having an elongated gripping portion and a piston head, wherein the piston head of the piston may have a cross-section corresponding to the internal cross-section of the filter beaker (specifically its body). In the case where the filter beaker may have a cross-section that varies along its longitudinal direction, the head portion of the piston may have a cross-section corresponding to the minimum internal cross-section of the filter beaker (specifically its body). The piston may be used to remove solid residues from the interior of the filter beaker, specifically by dragging the solid residues out of the body after the filter body is disassembled from the body, for example, by using a spoon, a pestle or the piston and / or the blending device itself. The longitudinal extension length of the elongated gripping portion of the piston may be greater than or equal to the longitudinal extension length of the body of the filter beaker.

[0057] Additionally or alternatively, an apparatus according to the present invention may include a container configured to receive a filter beaker therein, such that a liquid emulsion produced by the filter beaker through the action of a blending device received within the filter beaker can be collected in the container. In some embodiments, the apparatus may include a securing device for securing the position of the filter beaker relative to the container, specifically to prevent the filter beaker from moving relative to the container under the action of the blending device. The securing device may be included in the filter beaker and / or the container.

[0058] In some preferred embodiments, the receiving beaker may have a cross-section that is larger than the cross-section of the filter beaker, such that when the filter beaker is received in the container, at least one sidewall of the filter beaker is spaced apart from at least one sidewall of the container by a spacing distance. The spacing distance may be 1 cm to 15 cm, preferably 2 cm to 10 cm. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] For the purpose of promoting an understanding of the principles of the present invention, reference will now be made to certain preferred embodiments illustrated in the drawings, and specific language will be used to describe these embodiments. It will be understood, however, that the scope of the invention is not thereby limited, and that changes and further modifications to the illustrated apparatus and further applications of the principles of the invention illustrated therein are believed to be those which would normally occur now or in the future to one skilled in the art to which the invention pertains, within the scope defined by the claims.

[0068] Figure 1 The device for producing beverages known from WO 2013 / 120813 A1 discussed above is shown. The device includes a filter beaker 2 configured as a single-piece device. Therefore, after producing a beverage with solid ingredients using the filter beaker 2, it is difficult to dispose of the solid residue received in the filter beaker 2. Furthermore, the filter area 3 is integrated into the filter beaker 2, making it impossible to select different filter areas (e.g., with different filter sizes) to produce different beverages using the filter beaker 2.

[0069] Figure 2 A schematic perspective view of a filter beaker 10 according to some embodiments of the present invention is shown. The filter beaker 10 includes a tubular body 12 and a filter 14, which in this embodiment is configured as a tubular filter 14. The body 12 has a substantially cylindrical geometry, i.e., a constant, substantially circular cross-section and a sidewall 12w extending axially (longitudinally) between a top end 12t and a bottom end 12b of the body 12. The body 12 is completely hollow. Both the top end 12t and the bottom end 12b are open ends of the body 12.

[0070] The filter body 14 has a tubular geometry that matches the tubular geometry of the main body 12, which in this embodiment means that, like the main body 12, the filter body 14 also has a substantially cylindrical geometry, which has a circular cross-section both inside and outside that is substantially the same shape and size as the circular cross-section of the main body 12.

[0071] Figure 3 express Figure 2 A schematic side view of the filter beaker 10. Figure 3 As shown, the main body 12 has a longitudinal extension L M , i.e. the extension in the axial direction between its top end 12t and bottom end 12b, which corresponds to the longitudinal extension L of the filter beaker 14 F About 2 times of. Figure 3 In the exemplary embodiment shown, the outer diameter D of the main body 12 and the filter body 14 is 9 cm. The longitudinal (axial) direction of the main body 12 and the filter body 14 corresponds to Figure 2 、 Figure 3 、 Figure 4 (as well as Figure 8 、 Figure 9 、 Figure 13 、 Figure 14 、 Figure 17 、 Figure 18 、 Figure 19 、 Figure 20 and Figure 21 ) in the vertical direction on the paper.

[0072] The main body 12 and the filter body 14 may be attached to each other by means of a releasable coupling mechanism 30 which is Figures 2 to 7 In the exemplary embodiment shown, it is realized as a threaded mechanism comprising a male thread profile 11 arranged externally at the bottom end 12b of the main body 12 and a female thread profile arranged internally (at the top end 14t) at the connection portion 15 of the filter body 14. By means of the coupling mechanism 30, the main body 10 can be screwed into the receiving portion 15 of the filter body 14, so that a mechanically stable but still releasable connection is formed between the filter body 14 and the main body 12, which connection can also be fluid-tight.

[0073] In other related embodiments, a similar thread mechanism may include a male thread profile that may be externally disposed at the connection portion 15 of the filter body 14 and a female thread profile that may be internally disposed at the bottom end 12b of the main body 12. In any case, the filter body 14 and the main body 12 may be easily and securely attached to or detached from each other, similar to the upper and lower components of a conventional moka pot.

[0074] Figure 41 shows a schematic perspective view of the filter beaker 10 when the main body 12 and the filter body 14 are attached to each other. Figure 4 As shown, when the main body 12 and the filter body 14 are attached to each other, the sidewalls 12 w of the main body 12 and the sidewalls 14 w of the filter body 14 form a continuous smooth surface because the tubular geometry of the filter body 14 matches the tubular geometry of the main body 12 .

[0075] The filter body 14 comprises a base 17 which completely covers the cross section of the filter body 14. Figures 2 to 7 In the embodiment shown, the base 17 has a circular shape corresponding to the inner circular cross-section of the filter body 14. Figure 3 As shown by the dashed line, the base 17 of the filter body 14 can be arranged at a distance X from the top end 14t of the filter body 14 in the longitudinal direction. The base 17 is arranged in an axial (longitudinal) position between the connecting portion 15 (at the top end 14t of the filter body 14) and the bottom end 14b of the filter body 14. However, in other similar or related embodiments, the base 17 can be arranged at different longitudinal positions, such as at the top end 14t of the filter body 14 or at the bottom end 14b of the filter body 14 (specifically in an embodiment without the opening 19 that will be further described below for this embodiment). In other words, in different embodiments, the value of the distance X can be between substantially 0 and substantially L F within the range between.

[0076] The base 17 geometrically closes the interior space I of the filter beaker 10 at one axial (longitudinal) end (see Figure 4 ), so that the internal space I of the filter beaker 10 is formed by the side wall 12w of the main body 12 and the side wall 14w of the filter body 14. Figure 3 The filter beaker 10 is partially enclosed laterally with an extension X in the longitudinal direction shown, wherein the interior space I is further enclosed from below by the base 17 and is open from above at the top end 12t of the main body 12. Therefore, the total extension of the interior space of the filter beaker 10, which is respectively enclosed by the side walls 12w of the main body 12 and the side walls 14w of the filter body 14, is L M +X, such as Figure 3 shown.

[0077] The base 17 includes a filter area 20, Figures 2 to 6 In the exemplary embodiment shown, the filter area 20 is configured as a filter mesh made of steel wires interwoven to form a grid with openings having a regular pore size of 150 μm. The filter area 20 of the base 17 covers the entire cross-section of the base 17 (and therefore the entire cross-section of the filter body 14) except for a thin peripheral border having a radial extension of, for example, 1 cm or less, by which the base 17 is fixed to the rest of the filter body 14.

[0078] like Figures 2 to 4 As shown, the filter body 14 further includes a plurality of openings 19 formed as curved quadrilateral openings in the side wall 14w of the filter body 14, the openings 19 extending longitudinally upward from the bottom end 14b of the filter body 14 to a height H above the bottom end 14b (see FIG. Figure 3 ). The openings 19 are curved because they are formed in the curved (rounded) side wall 14w of the filter body 14. Figures 2 to 7 In the illustrated embodiment, the height H is less than the distance between the base 17 and the bottom end 14b of the filter body 14. However, in other related embodiments, the height H may substantially correspond to the distance between the base 17 and the bottom end 14b of the filter body 14, such that the opening 19 may extend from the bottom end 14b of the filter body 14 to the longitudinal (axial) position of the base 17. Figures 2 to 7 In the exemplary embodiment shown, the filter body 14 includes three openings 19 , however, other related embodiments may have more or fewer openings, such as one, two, four, five, or more openings.

[0079] Due to the presence of the openings 19, the side wall 14w of the filter body 14 has different extensions in the longitudinal direction at different locations around the periphery of the filter body 14. In those peripheral locations where the openings 19 are formed, the side wall 14w has a longitudinal extension L F -H (see Figure 3 In those peripheral positions where no opening 19 is formed, the side wall 14w has a longitudinal extension L F (See Figure 3 ), and each portion of the side wall 14w extending between adjacent openings 19 forms an upright portion 14p of the side wall 14w of the filter body 14.

[0080] therefore, Figures 2 to 7 The tubular cylindrical filter body 14 of the illustrated embodiment has a tooth-shaped structure, wherein each of the one or more openings 19 is formed as a hole or recess in the side wall 14 w of the filter body 14 and is arranged between two adjacent non-recessed portions (merlons) of the side wall 14 w of the filter body 14 corresponding to corresponding upright portions 14 p of the filter beaker 10.

[0081] If the filter beaker 10 is placed in a container (such as a glass or a jar) and the upright portion 14p rests on the base of such a container, i.e., serves as the "foot" of the filter beaker 10, the upright portion 14p laterally encloses a spatial region that is also enclosed from above by the base 17 of the filter body 14 and from below by the base of the container. This spatial region is fluidically connected to the outside through the opening 19 and to the interior space I through at least one filtering area 20 of the base 17. When the blending device received in the filter beaker 10 is in operation, its rotating blades can be arranged directly above the base 17 and can generate and drive a turbulent flow directed downward through the filtering area 20 of the base 17 and then radially outward through the opening 19 toward the bottom of the container.

[0082] Figure 5 Shown Figures 2 to 4 The top view of the main body 12 corresponds to the top end 12t of the main body 12 having a circular cross section. Figure 5 The top view shown in FIG. 1 is similar or identical to that shown in FIG. 2 , but the bottom end 12 b of the body 12 is shown instead.

[0083] Figure 6 Shown Figures 2 to 4 14, which corresponds to the top end 14t of the filter body 14 having a circular cross section. From this top view, the base 17 can be seen, which is attached to the side wall 14w of the filter body 14 and includes a filter area 20, the diameter of which is slightly smaller than the diameter of the base 17.

[0084] Figure 7 Shown Figures 2 to 4 14, which corresponds to the bottom end 14b of the filter body 14 having a circular cross-section. From this top view, the filter area 20 of the base 17 can be seen. Three openings 19 and three upright portions 14p formed as part of the side wall of the filter body 14 can also be seen. In the embodiment under consideration, all three openings 19 and all three upright portions 14p cover an equal 60° angle around the center of the circular cross-section of the filter body 14. In other related embodiments, a different number of openings 19 and / or upright portions 14p and / or different angular extensions thereof are also possible. In particular, the openings 19 do not have to have the same angular extension and / or be evenly spaced.

[0085] exist Figures 2 to 7In the illustrated embodiment, the main body 12 and the filter 14 can be made of or include the same plastic material. However, in other embodiments, the main body 12 and the filter 14 can be made of or include different materials. For example, the main body can be made of a food-compatible plastic, while the filter 14 can be made of or include stainless steel. The coupling mechanism 30 can be made of the same material as (or a different material from) the rest of one or both of the main body 12 and the filter 14.

[0086] Figures 8 to 12 A schematic diagram of a filter beaker 10 according to another embodiment of the present invention is shown. The filter beaker shares the above-mentioned Figures 2 to 7 Most of the structural features described in the illustrated embodiment are the same, so the same reference numerals are used to designate the same or related parts. Figures 8 to 12 The filter beaker 10 of the exemplary embodiment shown can be assumed to have the same Figures 2 to 7 The exemplary embodiments described have the same or similar features and characteristics.

[0087] according to Figures 8 to 12 The filter beaker 10 of the exemplary embodiment shown is similar to the filter beaker 10 of the exemplary embodiment shown in FIG. Figures 2 to 7 One of the differences between the filter beakers 10 of the exemplary embodiments described is that Figures 8 to 12 In the exemplary embodiment shown, the filter body 14 does not have openings and upright portions formed therein (see FIG. Figures 2 to 4 ). Thus, the side wall 14w of the filter body 14 has the same extension in the longitudinal direction over its entire circumference.

[0088] Another difference is that in Figures 8 to 12 In the exemplary embodiment shown, the releasable coupling mechanism 30 is configured as a bayonet mechanism comprising a plurality of radial protrusions 15' at the top end 14t of the filter body, the radial protrusions 15' being configured to be received and locked within a corresponding plurality of L-shaped slots 11' formed at the bottom end 12b of the main body 12. In the exemplary embodiment shown, two radial protrusions 15' and two corresponding L-shaped slots 11' are shown, but in other related embodiments, their number may be different, and in particular, may be greater.

[0089] Figures 8 to 12 The filter beaker 10 of the exemplary embodiment shown in FIG includes a sealing ring 9 configured to be arranged between the filter body 14 and the main body 12 when the filter body 14 and the main body 12 are attached to each other, so as to improve the fluid tightness of the mechanical connection between the filter body 14 and the main body 12. The sealing ring 9 can be made of a rubber material.

[0090] Another difference is that in Figures 8 to 12In the exemplary embodiment shown, the base 17 is not arranged at an intermediate longitudinal position between the bottom end 14b and the top end 14t of the filter body 14, but is instead arranged at the bottom end 14b, thereby closing the tubular filter body 14 from below, so that the inner space I of the filter beaker 10 is completely surrounded by the side wall 12w of the main body 12 and the side wall 14w of the tubular filter body 14.

[0091] In addition, Figures 8 to 12 In the exemplary embodiment shown, the filtration area 20 is arranged in the base 17 and also on the side wall 14 w of the filter body 14 and comprises a plurality of filtration holes respectively formed in the base 17 and the side wall 14 w of the filter body 14. The filtration holes of the filtration area 20 may have a diameter of, for example, 150 μm or any other filtration size mentioned above for the filter beaker according to the invention.

The base 17 includes part of the filter holes of the filter area 20, and the remaining filter holes are formed on the side wall 14w of the filter body 14. Figure 12 Also visible in the figure are two radial protrusions 15 of the bayonet mechanism 30 configured to be received and secured within the L-shaped slot 11' of the main body 12. The top view of the filter body 14 will be similar to the Figure 12 The bottom view shown is the same.

The filter beaker 10 shares the above-mentioned Figures 2 to 7 The embodiments shown and / or directed to Figures 8 to 12 Most of the structural features described in the illustrated embodiment are the same, so the same reference numerals are used to designate the same or related parts. Figures 8 to 12The filter beaker 10 of the exemplary embodiment shown can be assumed to have the same Figures 2 to 7 and about Figures 8 to 12 The exemplary embodiments described have the same or similar features and characteristics.

[0096] Figure 13 A schematic perspective view of a filter beaker 10 is shown, and Figure 14 The corresponding schematic side view is shown. Figures 13 to 16 The filter beaker 10 of the exemplary embodiment shown in FIG. Figures 2 to 7 or Figures 8 to 12 One of the differences between the filter beakers 10 of the exemplary embodiments described is that Figures 13 to 16 In the exemplary embodiment shown, the filter area 20 of the filter body 14 is configured as a filter mesh, as described with reference to FIG. Figures 2 to 7 As in the exemplary embodiment discussed above, however, the filter area 20 is now arranged on a base 17 which is arranged at the bottom end 14b of the tubular filter body 14, as described above for Figures 8 to 12 As in the described embodiment, the filter area 20 is also arranged on the side wall 14w of the filter body 14. The filter area 20 arranged on the side wall 14w of the filter body 14 covers the rectangular opening formed in the side wall 14w.

[0097] exist Figures 13 to 16 In the exemplary embodiment shown, the coupling mechanism 30 is configured similar to Figures 2 to 7 The thread mechanism 30 in the exemplary embodiment shown comprises a male thread profile 11 arranged at the bottom end 12 b of the main body, which can be screwed into a female thread profile arranged at the connecting portion 15 (top end 14 t ) of the filter body 14 .

[0098] according to Figures 13 to 16 The filter beaker 10 of the exemplary embodiment shown in FIG. Figures 2 to 7 or Figures 8 to 12 Another difference between the filter beakers 10 of the described exemplary embodiments is that Figures 13 to 16 In the exemplary embodiment shown, the body 12 comprises a flange 52 at its top end 12t, which is configured to serve as a fastening means for fixing the position of the filter beaker 10 relative to a container in which the filter beaker 10 can be received (by receiving the upper edge of the container therein). This flange corresponds functionally to the edge 5 known from the device described in WO 2013 / 120813 A1 (refer to Figure 1 ). Thus, the size and shape of the flange 52 can be adapted accordingly to match the geometry of the rim of a particular container. When the filter beaker 10 is secured to the container via the flange 52, the bottom end 14b of the filter body 14 may or may not rest on the base of the container.

[0099] Figure 15 Shown Figure 13 and Figure 14 FIG. 1 is a top view of the body 12 of the filter beaker 10 , in which the top end 12 t of the body 12 can be seen, and the flange 52 is formed in the top end 12 t of the body 12 .

[0100] Figure 16 Shown Figure 13 and Figure 14 FIG. 1 is a bottom view of the filter body 14 of the filter beaker 10 , in which the bottom end 14 b of the filter body 14 can be seen. A base 17 configured as a portion of a filter mesh and accommodating a filter area 20 is arranged at the bottom end 14 b of the filter body 14 . The remaining portion of the filter area is formed as a window in the side wall 14 w of the filter body 14 covered by the filter mesh, as shown in FIG. Figure 13 and 14 shown.

[0101] Figures 17 to 20 A schematic diagram of a filter beaker 10 according to another embodiment of the present invention is shown. The filter beaker shares the above-mentioned Figures 2 to 7 、 Figures 8 to 12 as well as Figures 13 to 16 The illustrated embodiments describe some structural features, and thus the same reference numerals are used to designate the same or related components where appropriate.

[0102] according to Figures 17 to 20 One major difference between the filter beaker 10 of the illustrated exemplary embodiment and the filter beaker 10 of the previously described embodiments is that Figures 17 to 20 In the exemplary embodiment shown, the filter body 14 does not have a tubular geometry, but instead has a disc-shaped geometry and is configured as the base of the filter beaker 10. In this embodiment, the body 10 has a tubular geometry and includes a plurality of upright portions 12p at its bottom end 12b, which functionally correspond to Figures 2 to 7 The upstanding portion 14 p of the illustrated embodiment is however formed in the main body 12 as part of the side wall 12 w of the main body 12 rather than in the filter body 14 .

[0103] Upright portion 12p extends in the longitudinal direction of filter beaker 10, and when received in the container, filter beaker 10 can stand on the bottom of the container using upright portion 12p. In this case, the presence of upright portion 12p means that a gap remains between the bottom of the container and filter body 14, which forms the base of filter beaker 10 and covers its cross-section. This gap corresponds to the vertical space between bottom end 12b and filter body 14, which is partially surrounded by upright portions 12p and openings 19 formed between adjacent upright portions 12p.

[0104] The filter body 14 can be removably attached to the main body 12 by means of a clamping mechanism 23. The disc-shaped filter body 14 can be introduced into the main body 12 via the bottom end 12b and moved upward past the biased clamping mechanism 23, which allows the filter body 14 to pass through but locks it in place between the clamping mechanism 23 and a retaining portion 21 of the filter beaker 10, which in the present exemplary embodiment is configured as an inner radial protrusion 21 of the main body 10. A sealing ring 9 is arranged between the filter body 14 and the inner radial protrusion 21.

[0105] like Figure 20 As shown, in this exemplary embodiment, the filter body 14 is arranged at an intermediate longitudinal position between the top end 12t and the bottom end 12b of the main body 12, and the longitudinal extension L of the tubular main body 10 is M Much larger than the longitudinal extension L of the disc-shaped filter body 14 F (L M >20L F ).

[0106] The filter body 14, which forms the base of the filter beaker 10, is received within the body 10 when the filter body 14 is attached to the body 12. The filter body 14 has a disc-shaped geometry that matches the tubular geometry of the body 12, which in this case means that the disc-shaped filter body 14 completely covers the inner circular cross-section of the tubular body 12.

[0107] according to Figures 17 to 20 Another difference between the filter beaker 10 of the illustrated exemplary embodiment and the filter beaker 10 of the previously described embodiments is that Figures 17 to 20 In the exemplary embodiment shown, the main body includes a first filter area 20-1 formed in a portion of the side wall 12w adjacent to and above the filter body 14 (see FIG. Figure 20), and the filter body includes a second filter area 20-2. The first filter area 20-1 has a first filter size, for example, 150 μm, and the second filter area 20-2 has a second filter size larger than the first filter size, for example, 300 μm or 500 μm. In other related embodiments, the first filter area 20-1 formed by the side wall 12w can extend vertically over a larger part of the vertical extension of the side wall 12w, that is, it can extend until it is aligned with the first filter area 20-1. Figures 17 to 20 The exemplary embodiment shown is a point further away from the filter body 14 .

[0108] exist Figures 17 to 20 In the exemplary embodiment shown, the filter beaker 10 further comprises a handle 7 for holding the filter beaker 10 .

[0109] Figure 21 1 shows a schematic perspective view of a kit 50 according to an embodiment of the present invention. The kit 50 includes a filter beaker 10, which includes a filter beaker 10 and a filter beaker 10. Figures 2 to 5 The exemplary bodies shown are identical to the main body 12, the first filter body 14-1 and the second filter body 14-2. Each of the filter bodies 14-1 and 14-2 of the kit 50 is identical to the main body 12, the first filter body 14-1 and the second filter body 14-2. Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 7 The tubular filter body 14 of the illustrated embodiment is similar, but does not have the opening 19 formed in its side wall. Each of the first filter body 14-1 and the second filter body can be removably and replaceably attached to the main body 12 using a corresponding releasable coupling mechanism. In the illustrated embodiment, the coupling mechanism is configured as a threaded mechanism that includes a male thread profile 11 located at the bottom end of the main body 12 and a female thread profile formed at the connecting portion 15 of each of the first filter body 14-1 and the second filter body 14-2, as shown. Figures 2 to 7 and Figures 13 to 16 This is the case with the embodiment shown.

[0110] The first filter body 14-1 and the second filter body 14-2 each include a base portion 17-1 and 17-2. In this embodiment, the base portions 17-1 and 17-2 are arranged at a longitudinal position between the corresponding top end 14t-1 or 14t-2 and the corresponding bottom end 14b-1, 14b-2, and are closer to the corresponding top end 14t-1, 14t-2 than to the corresponding bottom end 14b-1, 14b-2. However, as previously noted, in other embodiments, the longitudinal positions of the base portions 17-1 and 17-2 may differ. For example, in other related embodiments, the base portions 17-1 and 17-2 may be arranged at the bottom end 14b-1 or 14b-2 of the corresponding filter body 14-1, 14-2.

[0111] Each base 17-1, 17-2 includes a corresponding filter area 20-1, 20-1 formed as a filter mesh therein. The structural characteristics of the first filter body 14-1 and the second filter body 14-2 can be substantially identical, differing only in the filtration sizes of the filter areas 20-1 and 20-2. For example, the first filter body 14-1 can have a filter area 20-1 having a first filtration size that is smaller than the second filtration area 20-2 of the second filter body 14-2. In a more specific example, the first filter body 14-1 can have a filter area 20-1 having a filtration size of 150 μm, while the second filter body 14-2 can have a filter area 20-2 having a filtration size of 500 μm. Thus, a user of the filter kit 50 can attach the first filter body 14-1 to the main body 12 for producing a liquid emulsion from water and seeds (such as soybeans or tiger fruit), for which a filter size of 150 μm is more suitable, and can replace the first filter body 14-1 with the second filter body 14-2 by detaching the first filter body 14-1 from the main body and replacing it with the second filter body 14-2 by attaching the second filter body 14-2 to the main body 12 instead for producing a liquid emulsion from water and nuts such as peanuts, hazelnuts or cashews, for which a filter size of 500 μm is more suitable.

[0112] For the sake of simplicity, Figure 21 The exemplary kit 50 shown includes two filter bodies 14 - 1 and 14 - 2 . However, kits according to similar or related embodiments may include a greater number of filter bodies, such as three, four, or five, each of which may have a different filter size.

[0113] Figure 22 1 shows a schematic perspective view of a kit 50 according to another embodiment of the present invention. The kit 50 includes a filter beaker 10 having a main body 12 and a filter body 14, which are similar in structure to the filter beaker 10. Figures 2 to 7 The main body 12 and filter body 14 of the illustrated embodiment are similar. Specifically, the filter body 14 of the kit 50 further includes a plurality of openings 19 , wherein each opening separates two adjacent upright portions 14 p of the side wall 14 w of the filter body 14 .

[0114] However, instead of having a fixed base 17 (refer to Figure 1 ), Figure 22The filter body 14 of the kit 50 includes a first base configured as a first filter element 22-1 and a second base configured as a second filter element 22-2. Each of the first filter element 22-1 and the second filter element 22-2 is removably attached to the rest of the filter body 14 so as to geometrically close the internal space of the filter beaker. To this end, the first filter element 22-1 and the second filter element 22-2 can be configured to be attached to the side wall 14w of the filter body 14, for example, by resting on a step formed in the filter body 14 and / or by being fastened to the rest of the filter body 14 (for example, fastened to its side wall 14w) via an appropriate fastening device such as one or more screws, a clamping mechanism, etc., wherein the step is a radial recess extending completely or partially around the inner periphery of the filter body 14.

[0115] Figure 22 The kit 50 also includes a sealing ring 9, which can be arranged between the filter body 14 and the main body 12 and / or between one of the first filter element 22-1 and the second filter element 22-2 and the filter body 14 and / or the main body 12, so as to improve the fluid tightness of the mechanical connection between the filter body 14, the main body 12 and / or the first filter element 22-1 and the second filter element 22-2.

[0116] The first filter element 22-1 has a first filter size, for example, 1 mm, and the second filter element 22-2 has a second filter size different from the first filter size, for example, 300 μm. Figure 22 The user of the filter kit 50 can use the filter beaker 10 having the filter body 14 including the first filter element 22-1 for producing a liquid emulsion from fruits and / or vegetables and optionally milk and / or water, for which case a filter size of 1 mm is more suitable, and can use the filter beaker 10 having the filter body 14 including the second filter element 22-2 for producing a liquid emulsion from water and cereals such as rice or oats, for which case a filter size of 300 μm is more suitable.

[0117] For the sake of simplicity, Figure 22 The exemplary kit 50 shown includes two filter elements 22-1 and 22-2. However, kits according to similar or related embodiments may include a greater number of filter elements, such as three, four, or five, each of which may have a different filter size.

[0118] Figure 23A schematic diagram of an apparatus 100 according to an embodiment of the present invention is shown, comprising a filter beaker 10, a container 60 adapted to receive the filter beaker 10 therein, and a piston 40 adapted to be inserted into the filter beaker 10 so as to partially cover its cross-section. In some embodiments, the filter beaker 10 may be a filter beaker 10 of a kit according to an embodiment of the present invention, for example, according to Figure 21 or Figure 22 The filter beaker 10 of the kit of any of the described embodiments. In any case, as previously described, the filter beaker 10 includes a main body 12 and a filter body 14 removably attached to the main body 12.

[0119] exist Figure 23 In the exemplary device 100 shown, the body 12 of the filter beaker 10 has a widened portion 62 at its top end 12t, where the cross-section and / or diameter of the body 12 corresponds to the cross-section and / or diameter of the container 60, so that the widened portion 62 can serve as a fastening device for fixing the position of the filter beaker 10 relative to the container 60, particularly by a positive fit, when the filter beaker 10 is received in the container 60. In addition, the larger inner cross-section of the filter beaker 10 at the widened portion 62 simplifies the task of introducing the ingredients into the filter beaker 10.

[0120] exist Figure 23 In the exemplary device 100 shown, the container 60 is a substantially cylindrical container, for example made of plastic or glass, having a diameter of 12 cm and a height of 23 cm. Thus, the widened portion 62 of the filter beaker 10 has a diameter of 12 cm at its widest portion. Outside the widened portion 62, the filter beaker 10 (i.e., both the main body 12 and the filter body 14) can have a diameter of, for example, 8 cm. Thus, when the filter beaker 10 is received in the container 60, the filter beaker 10 can be fixed internally to the upper edge of the container by means of the widened portion 62, and the side wall 12 w of the main body 12 and the side wall 14 w of the filter body 14 are separated from the side wall 60 w of the container (excluding the widened portion 62) by a distance d. s However, the container 60 can have other geometric shapes and configurations. For example, a conventional kitchen pot can also be used as the container 60 of the device 100, in which case the spacing distance d s It could be much larger, perhaps 10 cm, 20 cm or more, and in this case the filter beaker 10 could have another type of fastening means (in addition to the widened portion 62) or no fastening means at all.

[0121] The piston 40 can be made of wood, metal, plastic, or any suitable material and has an elongated shape so that it can be inserted into the filter beaker 10. The piston 40 includes a piston head 40p having a cross-section that substantially corresponds to the inner cross-section of the filter beaker 10 (outside of the widened portion 62). The piston 40 also includes a grip portion 40g that can be ergonomically configured for hand-holding by a user.

[0122] Figure 24 Shown Shown Figure 23 Schematic cross-sectional side view of the filter beaker 10 and the container 60 of the device 100, wherein the filter beaker 10 is received in the container 60 and fixed to the container 60 against the inner side wall 60w of the container 60 by the surface fit of the widened portion 62 of the filter beaker 10.

[0123] like Figure 24 As shown, the filter beaker 10 rests on the base 60b of the container 60 with the upright portion 14p of the filter body 14 directly contacting the base 60b. Figure 24 Only one is shown in FIG. 1 , a void is formed within the filter body 14 between the base 60b of the container 60 and the longitudinal (vertical) position of the base 17. The base 17 includes one or more filter areas 20, and the sidewalls 14w of the filter body 14 may include additional filter areas or no filter areas. Figure 24 The figure also shows the spacing distance d between the inner side wall 60w of the container 60 and the side wall 12w of the main body 12 and the side wall 14w of the filter body 14. s . Spacing distance d s It may be 3 cm, for example.

[0124] In order to prepare a liquid emulsion from at least one solid ingredient and a liquid ingredient, at least one solid ingredient (e.g., nuts, seeds, and / or grains) is introduced into the interior space of the filter beaker 10. Then, an appropriate amount of liquid ingredient, such as water, is filled in the container, and the filter beaker 10 containing the at least one solid ingredient is introduced into the container 60, such as Figure 24 A blending device 70 (eg, a conventional hand-held mixer) is then inserted into the filter beaker 10 so that it is received within the main body 12 and filter body 14 .

[0125] When blending device 70 is activated, the rotational motion of the blades of blending device 70 pulverizes the at least one solid component received within filter beaker 10 and generates turbulent flow that mixes the (pulverized) at least one solid component with the surrounding liquid component. This turbulent flow is facilitated by the presence of filtration region 20 of filter body 14 and the vertical gap left by upright portion 14p between base 60b and base 17 of container 60. The flow driven by blending device 70 is directed downward from the interior of filter beaker 10 through filtration region 20 of base 17 of filter beaker 10, into the space enclosed by upright portion 14p and base 60b of container 60, and then deflected radially outward through opening 19. Simultaneously, filtration region 20 of filter body 14 further filters the at least one solid component, so that any particles of the at least one solid component larger than the filtration size of filtration region 20 remain within filter beaker 10 and are not dispersed into the surrounding liquid. After an appropriate mixing time (which may be, for example, between 1 and 3 minutes), the blending device 70 may be closed and removed from the interior of the filter beaker 10. The liquid emulsion is now contained in the container 60.

[0126] When the filter beaker 10 is removed from the interior of the container 60, remnants of at least one solid component remain inside the filter beaker 10, typically accumulating on the inner sidewalls of the main body 12 and / or the filter body 14. In order to completely dry the remnants of the at least one solid component still present in the filter beaker 10, the piston 40 or any other functionally equivalent element (such as a pestle, mortar, etc.) can be used to press the solid residue against the filtration area 20 of the filter body 14, thereby extracting the final liquid extract thereof. The piston can be configured as a heavy-duty piston weighing 2 kg or more (e.g., 5 kg), so that it can be used to press the solid residue by simply introducing it into the filter beaker 10 and letting gravity press the piston on the solid residue.

[0127] The filter body 14 can then be separated from the main body 12, and the residue of at least one solid component still inside the main body 12 can be easily disposed of by pushing the residue out of the main body 12 (e.g., manually) using a spoon or the piston 40 itself, as shown. Figure 25 Shown schematically.

[0128] like Figure 24 and Figure 25As shown, the side wall 12 w of the main body 12 includes an annular radial protrusion 41 that protrudes radially inward from the side wall 12 w of the main body 12. The radial protrusion 41 serves as a stopper for the piston 40. Before separating the filter body 14 from the main body 12, when the piston 40 is inserted into the filter beaker 10 for pressing the residue of at least one solid component still present in the filter beaker 10 after the action of the blending device 70, the radial protrusion 41 prevents the piston 40 from inadvertently damaging the base 17, in particular, the filtration area formed in the base 17.

[0129] Although preferred exemplary embodiments have been shown and described in detail in the drawings and the foregoing description, these should be considered as purely exemplary embodiments and not as limitations of the present invention. In this regard, it should be noted that only preferred exemplary embodiments have been shown and described, and all current or future variations and modifications that fall within the scope of protection of the present invention as defined in the claims should be protected.
