Description

Technical Field

[0001] This invention relates to an apparatus for producing personal care products, cosmetics or household products, particularly suitable for ready-to-use, non-industrial-scale, dosage products commonly found in homes. Background Technology

[0002] In home (i.e., private use, non-industrial) mixing and blending, existing techniques typically involve the use of a permanently mounted agitator directly connected to a motor via a drive shaft extending into the mixing vessel. The agitator used usually consists of a series of blades designed to break up coarse-particle components or mix liquids of varying densities. Such an agitator is described, for example, in document DE10053319A1. However, such agitators are unsuitable for dispersing small quantities of product, typically around 50 ml, because the components of the product to be manufactured tend to adhere to the rigidly mounted agitator and, due to the high rotational speed, become finely distributed within the vessel, and, particularly due to the high centrifugal force, adhere to the walls of the mixing vessel, making further mixing impossible. This results in considerable losses for small quantities, necessitating the production of far more than required to achieve the target yield.

[0003] Another problem arises particularly when the final product becomes very viscous after cooling in the mixing vessel. This necessitates removing the mixing equipment at specific points in time while the product is still liquid. This is impossible for permanently installed mixers.

[0004] U.S. Patent 10,631,686B1 discloses an impeller for food processing that uses a magnetically driven stirring device. The impeller includes a base that forms a transition portion between the stirring device and the magnetic drive, creating a gap.

[0005] In the production of personal care products, cosmetics, or household products, waxes or heat-labile substances are frequently used, requiring gentle heating. If, as specified in document DE10019126A1, a resistance heating element with wires applied to a dielectric is placed at the bottom of the mixing vessel, this element produces relatively localized heating, making it impossible to achieve adequate gentle heating in all cases. Localized heating can cause denaturation of the processed substances. To avoid such effects, water bath heating is used in laboratories or homes, but this method is both expensive and cumbersome in a home environment. Summary of the Invention

[0006] Therefore, the object of the present invention is to provide an apparatus, or a corresponding method, for producing personal care products, cosmetics, or household products, to solve or at least mitigate the aforementioned problems.

[0007] The above objective is achieved by a device having the features of claim 1 and a method having the features of claim 12.

[0008] Specifically, the objective is achieved by an apparatus for producing personal care products, cosmetics, or household products from at least two specified components, wherein the apparatus includes: A container, accessible on one side for containing the components, and having a container bottom. A heating device that surrounds the container from the outside, the heating device being adapted to the external shape of the container and in contact with the container to heat the components added to the container, and, An insert, which may be disposed inside the container near the bottom of the container. The insert includes a perforated stirring cage and a magnetic stirrer; the perforated stirring cage is fixed and / or rotated relative to the container at a predetermined position; the magnetic stirrer is rotatable relative to the stirring cage about a rotation axis, wherein the stirring cage at least partially surrounds the magnetic stirrer, and wherein the magnetic stirrer, in conjunction with the stirring cage and at least partially with the heating device, is configured to homogenize, disperse, emulsify, soften, melt, and / or pulverize components added to the container, and the magnetic stirrer can be driven by a magnetic or electromagnetic field penetrating the container wall, causing it to rotate relative to the bottom of the container, for example by a magnetic or electromagnetic actuator that can be disposed at the bottom of the container and driven by a motor, or by a coil assembly disposed near the bottom of the container and having multiple electromagnetic coils.

[0009] The aforementioned equipment can be used to produce personal care products, cosmetics, or household products for home use. For this purpose, the equipment homogenizes, disperses, emulsifies, softens, melts, and / or pulverizes at least two specified components (substances) in a container. The personal care products, cosmetics, or household products (hereinafter referred to as "products") can be made from solid components (including gels), powdered components, and / or liquid components, wherein any combination of these component types can be used. Another advantage of this equipment is its portability, as it is lightweight, small in size, and easily movable without the need for additional auxiliary equipment.

[0010] Furthermore, the advantage of the device of the present invention is that, due to the driving force of the magnetic stirrer and its interaction with the stirring cage, which will be described in more detail below, the rotational speed of the magnetic stirrer can be lower compared to the stirring equipment in conventional devices, which has a positive impact on, for example, the service life of the magnetic stirrer. As described below, the magnetic stirrer can have various shapes and sizes, which has the advantage that the magnetic stirrer can be replaced according to the quantity and properties of the components to be processed. For example, a smaller magnetic stirrer can be used when producing small quantities of personal care products, cosmetics, or household products, while a larger magnetic stirrer can be used when producing larger quantities of products.

[0011] In this application, personal care products are understood to include, for example, creams, lotions, shampoos, conditioners and similar products; cosmetics are understood to include, for example, blush, nail polish, lipstick and similar products; and household products are understood to include, for example, any type of cleaner, room fragrance or similar product used in the home.

[0012] The container (in which components for manufacturing a product can be introduced) has a rigid, robust shape (e.g., a hollow cylinder) with walls and a bottom that seals the container's base. Containers with rotationally symmetric cavities (e.g., cylindrical cavities) are advantageous because the magnetic stirrer within the container rotates about an axis of rotation relative to the stirring cage for product production. The container may comprise vertically extending cylindrical surface walls, or substantially cylindrical surface walls with further annular structures (e.g., annular partial notches or protrusions). In one embodiment, the container is open on the side opposite the bottom, allowing components to be inserted into this opening. This opening makes the container accessible and can be permanently, temporarily, or partially closed, for example, with a lid. In one embodiment, the inner side of the wall is in contact with the upper side of the bottom, where the inner side of the wall and the upper side of the bottom form the interior of the container.

[0013] In one embodiment, the container (stirring container) is made of at least one material selected from the group consisting of glass, aluminum, aluminum alloys, Teflon, stainless steel, and ceramics. In particular, glass can be advantageously used as the stirring container. This material allows for good product evaluation during the production process. The use of this material is feasible because a direct connection between the shaft and the drive motor is not required when using magnetic drive.

[0014] The exterior of the container is formed by the outer side of the walls (outer surface) and the lower side of the bottom. To ensure good contact with the container and the components to be treated within it, the heating device is configured to fit the external shape of the container. For example, the heating device may be at least partially in the shape of a hollow cylinder, wherein the heating device is in close contact with the exterior of the container, particularly in direct contact with the outer surface of the container, to achieve good direct heat transfer to the container material. The heating device completely surrounds the exterior of the container, or covers at least 50% of the outer surface of the container, to achieve a uniform temperature distribution. The heating device may surround only the walls of the container, or surround both the walls and the bottom. In one embodiment, the heating device may be directly arranged (e.g., as a heating wire, such as copper wire, or heating foil) on the outer surface of the container walls and / or the lower side of the container bottom (e.g., by adhesive). The heating device may optionally include at least one through-hole (e.g., a through-slot) through which a temperature measuring element can measure / observe the temperature of the container and / or the temperature of the components disposed within the container. Therefore, and to achieve the predetermined temperature profile well and quickly, the container wall is composed of or contains a material with good thermal conductivity, wherein the material includes at least one material selected from glass, aluminum, aluminum alloys, polytetrafluoroethylene, stainless steel, and ceramics. The heating device is used to bring the components to a predetermined temperature (i.e., heat or cool them) to achieve optimal homogenization, dispersion, or emulsification of the components. The heating device can be configured to achieve at least one predetermined temperature profile, which includes raising, holding, and / or lowering the temperature within respective predetermined time periods. The construction of such heating devices will be described in detail below.

[0015] Furthermore, the device includes an insert that can be disposed inside the container near the bottom of the container, wherein the insert is positioned near the bottom of the container. For example, the distance between the lower end of the insert and the bottom of the container is at most 1 cm, preferably at most 5 mm, wherein the insert can also be disposed directly on the bottom of the container without gaps. The insert can be inserted and removed through an opening in the container. Additionally, the insert can be attached (secured) to the container in a manner that is at least temporarily in a predetermined position relative to the container. The insert can extend from a position near the bottom to an area on the upper edge of the container via a linkage mechanism and / or a chassis and / or at least two connecting pillars (e.g., three connecting pillars), as described below, so that the magnetic stirrer and stirring cage can be accessed from above / outside the container. The linkage mechanism, chassis, or connecting pillars are connected to or integrally formed with the stirring cage, for example. In one embodiment, a handle may be provided at the upper end of the chassis, linkage mechanism, and / or connecting pillars protruding from the container, and a retaining element may be disposed on the handle. This allows the magnetic stirrer and stirring cage to be removed without reaching into the container or the device. Because the entire mixing system is externally accessible, personal care products, cosmetics, or household products are protected from contamination by bacteria from the user's skin microbiota. Alternatively, the insert can rotate relative to the container, wherein the magnetic stirrer and the mixing cage can rotate relative to the container individually or simultaneously, and / or rotate in the same or opposite directions of rotation. The attachment of the insert to the container can be permanent or detachable, for example, by a locking element (locking slider) that can move from an open (unlocked) position to a locked position in a handle disposed on the container or connected to the mixing cage. In the locked position, the locking element can engage with the shape of the container. In the open position, the insert can rotate within the container, thereby improving mixing performance when the mixing container is full. In one embodiment, the mixing cage and / or the mixing cage and a chassis fixedly connected to the mixing cage and / or a linkage mechanism fixedly connected to the mixing cage and / or at least two connecting struts fixedly connected to the mixing cage are configured to rotate relative to the container. In another embodiment, a retaining element, such as an annular one, is arranged axially on the insert at the end opposite the stirring cage and may include, for example, a flange resting on the edge of the container. The retaining element rotates relative to the container together with the stirring cage, the chassis and / or linkage mechanism and / or at least two connecting struts, because it is fixedly connected to, for example, the chassis and / or linkage mechanism and / or at least two connecting struts. Conversely, in the locked position, the insert, particularly the stirring cage (and, if applicable, the chassis / linkage mechanism / at least two connecting struts attached to the stirring cage, and, if applicable, the retaining element attached to these components), is fixed in the container and therefore immovable relative to the container; however, the magnetic stirrer can rotate relative to the stirring cage (and the container). In one embodiment, the chassis and / or linkage mechanism and / or at least two connecting struts may be configured to resist torsion.The chassis and / or linkage mechanism and / or at least two connecting struts may, for example, be connected to the retaining element via rubber adapters at their upper ends opposite the insert, the rubber adapters being inserted into the container and forming a clamping connection, for example, with the upper end of the container opening. If the insert is fully inserted into the container, the retaining element may, for example, have a stop surface / flange resting on the upper edge of the container opening. In this position, the rubber adapters may be pressed against the upper end of the container's inner wall via an interference fit, thereby securing the insert in place. In one embodiment, the rubber adapters may be provided with a bellows seal to absorb forces transmitted from the magnetic stirrer through the chassis to the retaining element. Furthermore, the retaining element may be closed from above by a cap.

[0016] According to the invention, the insert includes a stirring cage and a magnetic stirrer, wherein the magnetic stirrer is rotatable about a rotational axis extending relative to the stirring cage. For this purpose, the stirring cage may include, for example, a protruding mandrel or similar pivot bearing, which may be placed in (and possibly fixed in) a corresponding opening in the magnetic stirrer, such that the magnetic stirrer is rotatable about a fixed rotational axis formed by the mandrel. Alternatively, the magnetic stirrer may also rotate without being mounted on a mandrel, i.e., freely and relative to the stirring cage, and perform a rotational motion (oscillating motion) with a fixed or varying rotational axis. The magnetic stirrer is driven non-contactly by a corresponding rotating magnetic or electromagnetic field penetrating the container wall, which may be generated, for example, by an electric motor and a magnetic or electromagnetic actuator connected to the motor below the container. The magnetic or electromagnetic actuator is arranged outside the container and generates a rotating (electromagnetic) magnetic field that drives the magnetic stirrer located inside the container. Alternatively, a coil assembly comprising multiple electromagnetic coils may be provided arranged near the bottom of the container. The coil assembly may be rotatable or fixed to the device. In the latter alternative, the rotating (electromagnetic) magnetic field used to drive the magnetic stirrer is generated by appropriate excitation of an electromagnetic coil, which may be arranged, for example, in a ring shape. In both cases, motion relative to the stirring cage is generated. Therefore, a drive shaft penetrating the bottom of the container, as in the static actuator described above, is not required. If the container is arranged in a specified manner, the rotation axis of the magnetic stirrer may extend vertically, for example. The magnetic stirrer includes at least one permanent magnet (e.g., rod-shaped), which is integrally formed with the magnetic stirrer or can be inserted into a corresponding closable recess in the magnetic stirrer. The permanent magnet is driven by an electromagnetic or magnetic field applied from the outside and penetrating the bottom of the container. The stirring cage has a perforated structure and at least partially surrounds the magnetic stirrer. For example, the stirring cage has a disc-shaped bottom with a through hole, wherein the bottom is arranged between the magnetic stirrer and the bottom of the container. Furthermore, the stirring cage may include at least one edge configured to extend around the rotation axis of the magnetic stirrer. This edge may be formed, for example, on a protrusion projecting from the stirring cage parallel to the rotation axis of the magnetic stirrer, for example, projecting upward from a circular edge at the bottom (parallel to the rotation axis). These protrusions can be formed, for example, by corresponding flanges.

[0017] By using an easily movable magnetic stirrer, the rigid bladed agitator directly connected to the motor can be eliminated. This reduces product material loss. Another advantage is that the insert and magnetic stirrer can be removed from the container at appropriate times to save product material, such as when the product is in a liquid state. This magnetic stirrer is typically completely covered by the product material (components), thus achieving reduced "splattering" and consequently lower product loss. Furthermore, the stirring cage provides guidance and some constraint for the movement of the magnetic stirrer, so its rotation is advantageously conducted in a defined manner and can therefore be controlled in a defined manner. In this way, medium-volume production is possible, especially small and very small batches (e.g., 30 ml to 200 ml).

[0018] In one embodiment described above, at least in the corresponding modes (e.g., in the open or unlocked position of the handle), the stirring cage, along with the chassis and / or linkage and / or at least two connecting struts (if applicable), and the retaining element (if applicable), can rotate relative to the container. Rotation of the stirring cage and its attached elements is advantageous for homogenizing, dispersing, emulsifying, softening, melting, and / or pulverizing components, especially those with high viscosity added to the container from the outset or during production. Rotation can be performed, for example, at maximum speeds of 1000 rpm, 500 rpm, 400 rpm, 300 rpm, or 250 rpm. Using such maximum speeds has proven helpful in achieving good homogenization, dispersion, emulsification, softening, melting, and / or pulverizing effects on such components added to the container. The rotational speed of the stirring cage and its attached elements can be determined, for example, by a proximity sensor arranged above or in the area of ​​the upper edge of the container, and by observing, for example, markings on the chassis and / or linkage and / or one of the at least two connecting struts or the retaining element (optionally on its handle). In one embodiment, the magnetic stirrer and the stirring cage, as well as the elements connected to the stirring cage, may rotate in the same or opposite directions.

[0019] Furthermore, according to the present invention, the interaction between the magnetic stirrer and the surrounding stirring cage enables particularly good homogenization, dispersion, emulsification, softening, melting, and / or pulverization of small amounts of components added to the container at relatively low rotational speeds of the magnetic stirrer. This is because the rotation of the magnetic stirrer causes centrifugal motion of the components outward or towards the bottom of the container. As a result, they are driven towards the stirring cage, whose structure constitutes a motion barrier, thereby particularly supporting the homogenization, dispersion, emulsification, and / or pulverization of the components. The homogenizing effect of the stirring cage also promotes the melting and / or softening of the components.

[0020] In one embodiment of the above-described apparatus, as already described, the stirring cage includes at least one edge disposed in a region that radially surrounds the magnetic stirring body relative to the axis of rotation of the magnetic stirring body. The at least one edge may be blunt or blade-shaped, wherein the edge may extend circumferentially, partially or completely, around the magnetic stirring body at a predetermined radial distance. The edge may include a profile on its top side that supports the crushing of components. For example, the edge may include a wavy profile. In one embodiment of the above-described apparatus, the edge is formed on a protrusion projecting parallel to the direction of rotation, such as a flange extending upward (towards the container opening) from the outer edge of the annular base of the stirring cage.

[0021] In one embodiment of the aforementioned apparatus, the stirring cage includes at least two through-holes, for example, disposed in the bottom of the stirring cage between the magnetic stirrer and the bottom of the container. The openings may be disposed, for example, between the spoke-like elements of the stirring cage and have, for example, a triangular cross-section. In the bottom region of the stirring cage, the spoke-like elements may, for example, connect a spindle for the rotation axis of the magnetic stirrer to an annular element forming an edge. This further facilitates the homogenization, dispersion, emulsification, and / or pulverization of the components.

[0022] In one embodiment of the aforementioned apparatus, the stirring cage includes a surface structure, such as corrugations or bumps, on the surface opposite the magnetic stirrer, enabling the magnetic stirrer to interact more effectively with the surface and rotate the stirring cage. This interaction is particularly beneficial when the magnetic stirrer is not connected to the stirring cage, i.e., when there is no pivot bearing relative to the stirring cage.

[0023] In one embodiment, the mixing cage and / or chassis and / or linkage mechanism and / or at least two connecting struts connected to the mixing cage (if applicable) include a structure at the lower end of its surface opposite the bottom of the container, which also allows for better sliding of the mixing cage and / or chassis and / or linkage mechanism and / or at least two connecting struts connected to the mixing cage (if applicable). Such a structure may, for example, be a disc-shaped protrusion with a flat end face.

[0024] In one embodiment, the drive for rotation of the stirring cage and / or chassis and / or linkage mechanism and / or at least two connecting struts (if applicable) connected to the stirring cage, and optionally the retaining element, is provided by an electromagnetic coil disposed outside the container (e.g., at its upper end). Accordingly, the stirring cage and / or chassis and / or linkage mechanism and / or at least two connecting struts (if applicable) connected to the stirring cage and / or the retaining element (optionally) includes at least one magnetic element (e.g., a permanent magnet) causing the stirring cage and / or the element connected to the stirring cage (e.g., a rotor similar to a synchronous motor) to rotate. Alternatively, the rotational movement of the stirring cage and / or chassis and / or linkage mechanism and / or at least two connecting struts (if applicable) connected to the stirring cage, and optionally the retaining element, can be achieved by a magnetic stirrer that is forcefully engaged (frictionally) with the surface of the stirring cage (e.g., the surface facing the central disc element of the magnetic stirrer or the spoke struts of the stirring cage), and is thereby at least partially driven to rotate.

[0025] In one embodiment of the aforementioned apparatus, the magnetic stirrer includes at least one stirring blade extending obliquely and / or parallel to the axis of rotation, and / or includes at least one rod-shaped element extending parallel to the axis of rotation. The stirring blade may be formed as a straight, slightly curved, or arcuate element, having a blade-like shape on at least one side edge. For example, at least two side edges of the stirring blade are blade-like. Another example is that the stirring blade may protrude from the magnetic stirrer in the direction of and / or radially (relative to the axis of rotation), wherein the protrusion is designed to allow the magnetic stirrer to rotate within the stirring cage. The shape of the stirring blade may facilitate movement of the components toward the stirring cage, such as flow toward the bottom of the stirring cage. The stirring blade may also be configured such that larger fragments contained in the components are pulverized between the stirring blade and the flange when the magnetic stirrer rotates. Due to its shape and edges, the additional structure of the stirring blade further improves the homogenization, dispersion, emulsification, softening, melting, and / or pulverization of the components added to the container. Furthermore, the stirring blades can be shaped such that they apply force to the bottom of the container, pressing the magnetic stirrer against the bottom as it performs magnetically driven rotational motion for homogenizing, dispersing, emulsifying, softening, melting, and / or pulverizing components added to the container. This eliminates the need to attach the magnetic stirrer separately to the mixing cage and makes it easier to remove the magnetic stirrer after product production. Specifically, the force towards the bottom of the container is generated by a circumferentially extending surface on the magnetic stirrer, which slopes downwards against the direction of rotation, i.e., towards the bottom of the container. Therefore, the magnetic stirrer can be easily inserted and replaced by loosely inserting it into the mixing cage without the need for a "locking mechanism." No opening / locking is required because the magnetic stirrer stabilizes itself downwards due to the hydrodynamically designed stirring blades. A rod-shaped element can protrude from the side of the magnetic stirrer opposite the bottom of the container during installation and extends substantially parallel to the axis of rotation. The rod-shaped element ensures good homogenization of the components, even with large quantities.

[0026] In one embodiment of the aforementioned device, the container exterior has a substantially cylindrical shell surface. Furthermore, the heating device comprises a multi-layered structure and is at least partially hollow cylindrical in form. A dielectric heating element is arranged on one inner layer of the heating device, and this element is covered outwards with at least one insulating layer, which is at least partially composed of silicone foam and / or ceramic wool, wherein the thickness of the insulating layer can be at least 1 cm, for example, at least 2 cm. The layer with silicone foam is also referred to as a silicone pad. Other layers of the heating device may include ceramic wool, polytetrafluoroethylene (PTFE), fiberglass fabric, carbon fiber, and molded layers made of plastic materials or metal. The insulating element ensures good thermal insulation between the heating device and the outside, while the dielectric heating element ensures target temperature regulation of the components arranged within the container. The dielectric heating element may, for example, take the form of a serpentine or zigzag heating wire attached to a plastic film. A thin PTFE film may be provided on the inside of the plastic film to prevent the heating device from directly adhering to the outside of the container. Therefore, in relation to this invention, "inner layer" refers to another layer located on the inside, which is the innermost layer or a layer further inside than the outermost layer. This heating element ensures that the components arranged in the container are heated over a large area because the high flexibility of the material means that more than 50% of the container's surface is tightly surrounded by a large area, thus avoiding localized heating. The inner diameter of the heating device corresponds to the outer diameter of the container in this region to ensure a tight fit between the heating device and the container. Alternatively, the heating device can also be disposed directly on the outer surface of the container wall and / or the underside of the container bottom (e.g., glued). In this case, the heating device can be designed, for example, as a dielectric heating element in the form of a serpentine or zigzag heating wire attached to a plastic film.

[0027] In one embodiment of the aforementioned device, it includes an (optical) infrared temperature measuring element (pyrometer) disposed within a through-hole of the heating device and configured to measure the temperature of components located within the container. The temperature measuring element advantageously enables non-contact measurement of the temperature of components disposed within the container, thereby minimizing any impact on the components. Furthermore, such a temperature measuring element requires only a small installation space, which can be achieved through the through-hole described in the heating device, which substantially corresponds to the external dimensions of the temperature measuring element. For example, the temperature measuring element may be arranged to detect the component temperature in the region of a stirring cage and / or a magnetic stirrer. As described in detail below, the heating device can be controlled based on the temperature detected continuously or at predetermined time intervals by the temperature measuring element.

[0028] Alternatively or additionally, a resistance temperature measuring element and / or a diode temperature measuring element may be provided, which utilizes the temperature dependence of the band gap to measure the temperature of a component disposed within a container. This resistance temperature measuring element and / or diode temperature measuring element may be disposed within a through-hole of a heating device or embedded in the material of an insert, such as in the material of a stirring cage and / or a chassis and / or a linkage mechanism and / or one of the connecting pillars connected to the stirring cage. Alternatively or additionally, a pH measuring element may be provided for measuring the pH value of a component located within a container. This pH measuring element may be disposed within a through-hole of a heating device or embedded in the material of an insert, such as in the material of a stirring cage and / or a chassis and / or a linkage mechanism and / or one of the connecting pillars connected to the stirring cage.

[0029] Measurement data from infrared temperature measuring elements and / or resistance temperature measuring elements and / or diode temperature measuring elements and / or pH measuring elements can be transmitted to internal and / or external computing units, for example, via Bluetooth® connection or other wireless connection, wherein the corresponding electronic components (e.g., transmitters / receivers) connected to the temperature measuring element or pH measuring element can be embedded in the corresponding element as well as in elements directly connected to the corresponding element.

[0030] In one embodiment, the temperature measuring element is unaffected by radiant heat from the heat storage unit because the aforementioned silicone pad has only low heat storage characteristics, resulting in a very low proportion of radiant heat. The silicone pad may include a through-slot extending parallel to the axis of rotation, allowing the temperature measuring element to be positioned. The required open space for the temperature measuring element can be easily created by cutting the silicone pad with intervals. This configuration can be used to determine the temperature of the component being processed in real-time online via a non-contact infrared temperature measuring element throughout the production process.

[0031] In one embodiment of the aforementioned device, it includes a weighing platform configured to allow a movable unit, comprising a container with a heating device, an insert, and a motor, to be placed thereon, wherein the weighing platform is configured to measure the weight of the unit. In this embodiment, the device may, for example, include two elements: a movable unit and a weighing platform unit, the weighing platform unit including the weighing platform, and in one embodiment, a base for securely and vertically positioning the weighing platform on a surface (e.g., a tabletop). The movable unit may be arranged at a predetermined position on the weighing platform. The weighing platform is used to measure the weight of components disposed within the container to simplify the process of adding components according to a formulation. In one embodiment, a multi-head scale (e.g., a four-head scale) is used, which achieves accurate results within the weight range of the aforementioned components.

[0032] In one embodiment of the aforementioned device, the device includes an internal computing unit configured to control a motor and / or a heating element, and to receive temperature measured by a temperature measuring element and / or pH value measured by a pH measuring element. The computing unit may, for example, be arranged in the motor area below the container. In one embodiment, the computing unit is connected to the motor and / or heating element and / or temperature measuring element for data and / or control signal transmission. Furthermore, the internal computing unit may be connected to the scale body. Accordingly, the motor (e.g., its rotational speed) and / or heating element (i.e., the applied temperature) may be adjusted or controlled based on temperature and / or weight data determined and transmitted to the internal computing unit. As described above, heating and / or temperature profiles may be implemented, for example.

[0033] In one embodiment of the aforementioned device, the internal computing unit includes a receiver and / or transmitter for exchanging data with a corresponding external computing unit. This can be used to control and / or adjust the device and its aforementioned components / units via the external computing unit (i.e., remotely). Such an external computing unit can be a server or a smartphone. For example, product recipes or production data can be transmitted from a server and then implemented in the device. The recipe includes, for example, information about the quantity of components to be used and / or the timing of adding the corresponding components. Production includes, for example, temperature profiles and information about the motor speed (and thus the magnetic stirrer speed), which can also be represented in curve form. In such a speed profile, it can be determined in which time period the motor continuously increases, decreases, or maintains a constant speed, and in each case, which speed is achieved.

[0034] In one embodiment, all components of the device may be protected by a hollow cylindrical sleeve that includes a window through which indicator lights can be observed. For example, the indicator lights can be used to display the operating status of the device.

[0035] The aforementioned objective is further achieved by a method for producing cosmetics or cleansing agents from at least two specified components using the aforementioned equipment, wherein an internal computing unit is provided to automatically adjust and / or control: a predetermined rotational speed or predetermined rotational speed profile of a motor driving a magnetic stirrer, or a predetermined excitation of a coil assembly having multiple electromagnetic coils located near the bottom of the container; and a predetermined temperature or predetermined temperature profile of a heating device for homogenizing, dispersing, emulsifying, softening, melting, and / or pulverizing the components added to the container. To achieve this method, the computing unit has a memory containing data regarding rotational speed and temperature, which can be specified as setpoints for adjusting or controlling the motor or heating device. The memory may also contain formulation data, which can be displayed, for example, on a display on the equipment, to inform the user of the amount and quantity of which components should be added to the container at what time.

[0036] In one embodiment, when adjusting the temperature or temperature profile of the heating device and / or adjusting the rotational speed or rotational speed profile, the temperature measured by, for example, an infrared temperature measuring element and / or a resistance temperature measuring element and / or a diode temperature measuring element, and / or the weight value measured by the weighing body and / or the pH value measured by a pH measuring element are taken into consideration. The temperature and / or weight values ​​may be measured continuously or at predetermined intervals and are taken into consideration when adjusting the temperature and / or rotational speed.

[0037] In one embodiment, the total pH value of the product (i.e., the pH value present in the final product) can be determined based on the pH values ​​of the various n components and the amounts of each component added in the production process, and, if applicable, the total pH value is compared with the pH value measured by a pH measuring element. The calculation unit can implement this method for calculating the total pH value of the produced product based on the pH values ​​of the various n components and the weight of each added component. The following calculations are used for this purpose: pH = (w1·p1 + w2·p2 + w3·p3 + ... + wn·pn) / (w1 + w2 + w3 + ...+ wn), Where p1, p2, p3, ..., pn are the pH values ​​of the corresponding components in the n components, and w1, w2, w3, ..., wn are the weights of each individual component in the n components. The pH values ​​of the components (e.g., average pH values) can be stored in memory or input by the user. The total pH value (optionally along with the measured pH value) is then displayed on the aforementioned display for the user. Furthermore, the method can specify the type and amount of components that can be added to the product to achieve a predetermined total pH value (e.g., pH=5.5). The components to be added can be, for example, citric acid to shift the total pH value to a more acidic range, or sodium carbonate to shift the total pH value to a more alkaline range.

[0038] In one embodiment, the computing unit may determine the total price of the produced product based on the price of the components stored in memory and the amount of components added to produce the corresponding product, and optionally display this on a display for the user. Alternatively or additionally, the computing unit may monitor for the user whether the purchased components have been used up and optionally need to be replaced (i.e., repurchased). To this end, the computing unit detects (e.g., via a barcode reader) the purchased components and their corresponding quantities. This information is also captured when the components are used to produce the product through the equipment, thereby determining how much of the corresponding component has been used up or how much of the component remains in stock. If it is determined that the stock of the corresponding component has fallen below a predetermined threshold, the user is notified, for example, via a display, that the corresponding component must be repurchased. In an extended version of the method, in this case, the data for reordering components can be automatically transmitted to the vendors of these components (e.g., via a server and the Internet accessible through the server).

[0039] A computing unit (also referred to as a controller, control device, or control unit) may include a processing unit and a memory (also referred to as a storage unit) storing computer-executable instructions for performing the methods described herein. The processing unit or other described unit may include any suitable device configured to perform a series of steps to implement the methods, such that when the instructions are executed by a computing device or other programmable device, the functions / actions / steps specified in the methods described herein are performed. The processing unit or other unit may include, for example, any type of general-purpose microprocessor or microcontroller, digital signal processor (DSP), central processing unit (CPU), integrated circuit, field-programmable gate array (FPGA), reconfigurable processor, other suitable programmable or programmable logic circuitry, or any combination thereof. The memory may be any suitable known or other machine-readable storage medium. The memory (data carrier) may be a non-volatile computer-readable storage medium, such as an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, or any suitable combination of the foregoing. The memory may include any suitable combination of computer memories, whether located inside or outside the device or computing unit, such as random access memory (RAM), read-only memory (ROM), optical disc read-only memory (CD-ROM), electro-optical memory, magneto-optical memory, erasable programmable read-only memory (EPROM) and electrically erasable programmable read-only memory (EEPROM), ferroelectric RAM (FRAM), etc. The memory may include any storage device (e.g., a device) suitable for retrievably storing computer programs executable by a processing unit. The methods described herein may be implemented in a high-level procedural or object-oriented language or scripting language, or a combination thereof, to communicate with or support the operation of the control device or processing unit. Alternatively, the processes described herein may be implemented in assembly language or machine language. The language may be a compiled language or an interpreted language. Program code used to implement the methods described herein may be stored on a storage medium or device, such as ROM, disk, optical disc, flash drive, or any other suitable storage medium. When the storage medium or device is read by a computer to execute the processes described herein, the program code may be read by a general-purpose or special-purpose programmable computing unit to configure and operate the computer. Computer-executable instructions (computer programs) can take many forms, including program modules that are executed by one or more computers or other devices. Program modules typically include routines, programs, objects, components, data structures, etc., that perform certain tasks or implement certain abstract data types. Generally, the functionality of program modules can be combined or distributed in different embodiments as needed.

[0040] Therefore, the above objective is achieved by a computer program having program code stored on a machine-readable data carrier, which, when read by a computing unit (computer) and executed on the computing unit (computer), performs the method steps according to the above method.

Detailed Implementation

[0043] exist Figures 1 to 8 The first embodiment of a portable device for producing personal care products, cosmetics, or cleaning agents (products) is shown in detail, wherein the product is produced from at least two components. The components may, for example, consist of water, oil, detergent, active ingredients, etc.

[0044] The equipment includes a container 1.1. in which products are produced through homogenization, dispersion, emulsification, softening, melting, and / or pulverization. The entire equipment is protected by a hollow cylindrical sleeve 1.3., which includes an upper part 1.2. An indicator light 1.4.a with an observation window 1.4. is arranged on the lower part opposite the upper part 1.2. This indicator light 1.4.a indicates the operating status of the equipment (e.g., green: ready to run, red: fault). The sleeve 1.3. gives the equipment an attractive appearance, provides an additional layer of thermal insulation, and, thanks to its vertical corrugated structure, provides a good grip when the user wants to remove the sleeve 1.3. or move the entire equipment.

[0045] In particular, from Figure 3 and Figure 4 As can be seen, a heating device 1.5 with an infrared temperature measuring element 1.6 is provided inside the sleeve 1.3, with the container 1.1 positioned inside the hollow cylindrical heating device 1.5. Below the container 1.1, a magnetic drive body 1.7 (with a permanent magnet) is provided, which is connected to a drive shaft 1.7.a, driven by a motor 1.8 located below it. The device also includes a fan 1.9 on each side of the motor 1.8, which cools the motor during operation.

[0046] All the aforementioned components of the device are arranged on a four-head scale, as shown above, which allows the weight of these components to be determined in area 1.11. The disc and the corresponding four force sensors are not shown here. Since the components are located inside container 1.1, their weights can be determined accordingly using the four-head scale. The device also includes a circular plate-shaped base 1.12.a, which ensures the device is securely and vertically mounted on a support (e.g., a table or workbench) and that the interior of the device is sealed at the bottom. Indicator light 1.4.a is attached to base 1.12.a. Furthermore, a retaining plate 1.12. is provided on base 1.12.a, extending upward parallel to the rotation axis 3 and used for attaching electronic components. For example, an internal calculation unit (not shown) including the aforementioned components is arranged on retaining plate 1.12. The internal calculation unit is connected to the heating element of heating device 1.5, temperature measuring element, four-head scale, and motor 1.8. The computing unit controls the heating element and motor 1.8 based on the measurements from the temperature measuring element and the four-head scale. Furthermore, an energy supply device (e.g., battery, transformer, or power supply unit) is provided on the holding plate 1.12, which is connected to the four-head scale, motor 1.8, temperature measuring element, and heating element of the heating device 1.5, providing the energy required to operate these elements. A transceiver connected to the internal computing unit is also provided on the holding plate 1.12, enabling the exchange of regulation and / or control data and measured values ​​with an external computing unit (e.g., a server or smartphone via Bluetooth).

[0047] To produce this product, insert 2 (see [link to insert 2]) with magnetic stirrer 2.5 and stirring cage 2.6 is inserted. Figure 5The insert 2 is positioned within container 1.1, such that it is only a few millimeters (e.g., 2 mm to 8 mm) from the bottom of container 1.1. The insert 2 is detachably secured within the container by a retaining element 2.1. with an outer diameter corresponding to the inner diameter of container 1.1. For this purpose, the rubber adapter 2.2. has an interference fit on the inner side of the upper end of container 1.1. The rubber adapter 2.2. has the shape of a bellows seal for absorbing forces transmitted from the insert 2 to the chassis 2.2.a during production within the container. The retaining element 2.1. also has a stop surface 2.1.a that rests on the upper edge of container 1.1. when the insert 2 with chassis 2.2.a and retaining element 2.1. is positioned in a predetermined position within the container. The chassis includes three rods 2.2.a, to which the stirring cage 2. is attached. The upper ends of the three rods 2.2.a are connected to the retaining element 2.1. (As follows) Figure 6 As shown, the fixing of each rod is removable, for example, by screws.

[0048] exist Figure 6 As can be seen, the magnetic stirrer 2.5 is essentially a thick rod-shaped component, with two stirring blades 2.3 protruding obliquely from the rod-shaped portion. Furthermore, the magnetic stirrer 2.5 includes two openings 2.4, which are formed transversely to the rotation axis 3 and parallel to each other, each opening for receiving a bar magnet (not shown). The openings 2.4 can be closed and reopened after the corresponding bar magnet is inserted. The stirring cage 2.6 includes a central spike 2.6.b protruding along the rotation axis 3, to which the magnetic stirrer 2.5 is rotatably attached, such that the magnetic stirrer 2.5 rotates relative to the stirring cage 2.6 about the rotation axis 3 in a defined position. Through the rotation of the magnetic stirrer 2.5, the components located in this region of the container 1.1 are moved outward by centrifugal force and other forces exerted by the stirring blades 2.3, thereby abutting against the edge 2.6.a of the stirring cage 2.6 or against the bottom of the container 1.1. The bottom of the stirring cage 2.6. includes spoke-shaped supports 2.6.c and through holes 2.6.d located between them. When the components move in this direction due to the magnetic stirrer 2.5., the spoke-shaped supports 2.6.c and through holes 2.6.d facilitate the homogenization, dispersion, emulsification, softening, melting, and / or pulverization of the components added to the container. The corrugated edge 2.6.a also supports the homogenization, dispersion, emulsification, softening, melting, and / or pulverization of the components added to the container.

[0049] Figure 7 , Figure 8 and Figure 8aA heating element 1.5 of the device is shown. The heating element 1.5 includes a plastic film (not shown in detail) supporting a dielectric heating wire (e.g., copper wire) embedded therein, which extends in a zigzag manner through the entire plastic film. This plastic film is disposed within a heat-dissipating hollow cylindrical first layered element 3.2 having a bottom 3.3 and extends almost entirely along the layered element 3.2. The thickness of the first layered element 3.2 is at least 0.5 cm. Furthermore, a second hollow cylindrical layered element 3.4, made of plastic, aluminum, carbon fiber, or other composite material, surrounds the first layered element 3.2 on the outside. Optionally, a layer of ceramic wool is arranged between the first layered element 3.2 and the second layered element 3.4. A container 1.1 is disposed inside the first layered element 3.2, wherein the first layered element 3.2, carrying at least one heating element, surrounds the container 1.1 in a planar-sealed manner and is in direct contact with the exterior of the container 1.1. The first layered element 3.2 includes a through slot 3.1 extending parallel to the rotation axis 3, through which an infrared temperature measuring element protrudes. A through hole 3.5 for the infrared temperature measuring element is provided in the second layered element 3.4. The infrared temperature measuring element is configured to determine the temperature of the components located within the container 1.1 and transmit it to an internal computing unit.

[0050] Figure 8a An example of the layer structure of the first layered element 3.2. is shown in cross-section, wherein the layer structure can be varied (e.g., the aluminum foil layer can be omitted). From the outside to the inside, the first layered element 3.2. includes an aluminum layer 3.2.a, an aluminum foil 3.2.b, a rubber layer 3.2.c, a silicone foam layer 3.2.d, an electrically insulating plastic layer 3.2.e with an embedded dielectric heating wire, another rubber layer 3.2.f, another aluminum foil 3.2.g, and a polytetrafluoroethylene layer 3.2.h. The outer aluminum layer 3.2.a encloses the other layers of the first layered element in the form of a shell, thus functioning as an outer casing. The layer surrounding the silicone foam layer 3.2.d is designed to hermetically seal the silicone foam layer 3.2.d. The heating wire of layer 3.2.e generates heat and is connected to a power supply unit for this purpose, wherein the power supply is controlled by a computing unit. The inner PTFE layer 3.2.h ensures that the heating device 1.5. does not adhere to the container 1.1., which is positioned inside and heated by the heating device 1.5. when the device is used to produce personal care products, cosmetics, or household products. The bottom 3.3. has the same layer structure as the first layered element 3.2., wherein in the bottom 3.3., the aluminum layer 3.2.a is arranged at the bottommost position and the PTFE layer 3.2.h is arranged at the topmost position, and these layers also have the same function and operating mode as the first layered element. Accordingly, the PTFE layer 3.2.h is lined inside the assembly consisting of the first layered element 3.2. and the bottom 3.3.

[0051] Alternatively, it can be used Figure 9 , Figure 10 and Figure 10a The heating device 3.7 shown replaces heating device 1.5. The advantage of this heating device is that it is easier to manufacture compared to heating device 1.5 because silicone foam is relatively difficult to process. Heating device 3.7 consists of three elements, including an inner layer element 3.8. The inner layer element 3.8 is a metal-sheathed dielectric heating element in the form of a hollow cylindrical sheath, having a continuous groove 3.8.1 extending parallel to the axis, and an angled section 3.8.2 on each side of the continuous groove 3.8.1. Heating device 3.7 also includes a disc-shaped heating element in the form of a bottom 3.10, whose structure and material correspond to the inner layer 3.8. Furthermore, a central insulating layer 3.9 is provided, which may be composed of, for example, ceramic wool, and may also be in the form of a hollow cylindrical shell, having a continuous groove 3.10.1 extending parallel to the longitudinal axis. The heating device 3.7. is surrounded by a covering layer 3.11., which contacts and surrounds the central insulation layer 3.9 on the outside.

[0052] 3.8. Inner layer elements. Figure 10a The layered structure shown in cross-section is variable (e.g., the aluminum layer may be omitted). A first aluminum layer 3.8.a is arranged externally. Subsequently, a ceramic wool layer 3.8.b, a second aluminum layer 3.8.c, an electrically insulating plastic layer 3.8.d with an embedded dielectric heating wire, and a third aluminum layer 3.8.e are arranged sequentially towards the interior. The second aluminum layer 3.8.c and the third aluminum layer 3.8.e form an aluminum shell for layer 3.8.d with the dielectric heating wire. The heating wire in layer 3.8.d generates heat and is connected to a power supply device, wherein the power supply is controlled by a computing unit. The inner aluminum layer 3.2.e prevents the heating device 3.7. from adhering to the container 1.1., which is positioned inside the heating device 3.7. and heated by the heating device 3.7. when the device is used to produce personal care products, cosmetics, or household products. The bottom layer 3.10 has the same layer structure as the inner layer element 3.8, wherein in the bottom layer 3.10, the first aluminum layer 3.8.a is arranged at the bottommost position and the third aluminum layer 3.8.e is arranged at the topmost position, and these layers also have the same functions and operating modes as the inner layer element 3.8.

[0053] In the regions of the overlapping elongated slots 38.1 and 39.1 of the inner layer element 3.8 and the central insulating layer 3.9, there is an angled section 3.11.1 and a U-shaped profile 3.11.2 (e.g., made of aluminum), both extending parallel to the longitudinal axis of the covering layer (originally a hollow cylindrical shell). Similar to the description of the heating device 1.5 above, the infrared temperature measuring element can determine the temperature of the product arranged in the container through the groove in the profile 3.11.2 and the elongated slots 3.8.1 and 3.9.1.

[0054] To produce the product, container 1.1 is positioned within heating device 1.5. The components required for producing the product are then added simultaneously or sequentially to the container opening located at the top. A display provided on the device shows the weight of each component as measured by a four-head scale. When at least some components have been added to container 1.1, an insert 2 with a base 2.2.a and a retaining device 2.1. is inserted into the container opening until the stop surface (flange) 2.1.a rests on the upper edge of container 1.1. At this point, the insert is in the correct position and fixed relative to container 1.1. Subsequently, the heating element of heating device 1.5 and the rotational speed of motor 1.8 are adjusted by a calculation unit to execute a predetermined temperature and rotational speed curve. During this process, the temperature in the container is continuously monitored by a temperature measuring element, and the total weight of the components is measured by the four-head scale and transmitted to the calculation unit for evaluation; this weight data is optionally incorporated into the adjustment logic. Once both curves have been executed, the product is complete, and insert 2 can be removed from container 1.1 without significant loss of components. Subsequently, the finished product (cosmetics or cleaning agent) can also be removed from container 1.1.

[0055] In another embodiment, a display may be provided on the device or connected to the device, on which data related to the formulation of a personal care product, cosmetic, or household product selected by the user of the device may be displayed. This data is determined by the computing unit and transmitted to the display. For example, the user can understand when each component needs to be added and in what quantity. This can be correlated with the temperature and rotation speed curves described above. Furthermore, as described in detail above, the pH value of the produced product and the amount of acidic or alkaline component required for the desired pH value can be calculated and displayed. This greatly facilitates the production of products with the desired pH value. As mentioned above, the computing device may also be configured to determine the price of the product (produced according to the corresponding formulation) and display it on the display. In addition, based on the corresponding calculations of the computing unit, the user can be notified of low inventory quantities of components, and the corresponding ordering possibilities or delivery orders for these components can be transmitted. This is described in detail above.

[0056] Figure 13The magnetic stirrer 22.5 shown includes two rod-shaped elements 22.7, which protrude from one side of the cuboid central portion 22.5.a, facing away from the bottom of the container in the working position within the stirring cage or container. The rod-shaped elements 22.7 extend generally parallel to the rotation axis 22.6.e, shown as a dashed line. The rod-shaped elements 22.7 enable good mixing of components when producing a relatively large quantity of product, thus occupying a large proportion of the container volume. The protruding rod-shaped elements 22.7 also allow for mixing of product areas located further above the bottom of the container.

[0057] Figure 14 The magnetic stirrer 32.5 shown includes an integrated stirring blade 32.3 formed on the radial end of the central portion. This magnetic stirrer 32.5 is extremely compact and particularly suitable for small batches of products with minimal product adhesion. In the rotation direction R, each stirring blade 32.3 includes a circular section 32.3.a on its front side and an inclined tapering section 32.3.b on its back side. In the installed state, the top side of the tapering section 32.3.b extends against the rotation direction R towards the bottom of the container and applies a force towards the bottom of the container. Figure 14 The axis 32.6.e is also shown in dashed lines.

[0058] refer to Figures 15 to 17 A third embodiment of this device is described. Figure 15 The insertion was shown Figure 16 and Figure 17 The insert in container 41.1. Apart from some differences explained below, this device corresponds in its structure and operating principle to... Figures 11 to 12 The second embodiment is shown. Therefore, the same elements use the same reference numerals, but the value of these reference numerals is increased by 30. For example, the holding element 12.1 in the second embodiment corresponds to the holding element 42.1 in the second embodiment.

[0059] Figures 15 to 17 The embodiments of the apparatus of the present invention shown are particularly suitable for producing products with higher viscosity. For example... Figure 16 and Figure 17 As shown, the retaining element can be secured in the container 41.1 by means of the arcuate groove 42.1.b provided on the plastic or metal adapter 42.1., via the locking element 41.1.c. This embodiment is capable of generating a vortex effect in very viscous products. While a small magnetic stirrer only produces a vortex effect for small quantities of product, for larger quantities of product, a larger stirrer is required (see, for example...). Figure 13(Example). However, even with larger magnetic stirrers, vortices may not be generated at certain product volumes, especially at very high product viscosities. It has been proven that incorporating a guide rod into the stirring rotation process effectively generates a vortex effect, even at higher viscosities. In this case, the frictional resistance of the magnetic stirring element within the stirring cage causes the stirring cage 42.6, rod 42.2.a, and retaining element 42.1. to rotate together within the viscous product in container 41.1. However, if this function is not required, an arcuate groove 42.1.b can be used to suppress the rotation of the stirring cage 42.6. and rod 42.2.a (see Example). Figure 16 (The image shows the locked position of locking element 41.1.c). This is achieved by engaging locking element 41.1.c with the shaped groove 42.1.b, thereby preventing movement of the insert. This can be easily achieved by the user pushing locking element 41.1.c back and forth in the handle 41.1.b located at the top of the container 41.1. Conversely, Figure 17 The open position of locking element 41.1.c is shown, in which locking element 41.1.c is not engaged with groove 42.1.b. In the open position, the insert can rotate within container 41.1.

[0060] Figures 18 to 20 The fourth embodiment of the apparatus shown (without housing) for producing personal care products, cosmetics, or household products differs from the embodiments described above, particularly in the design of the drive mechanism. Figure 18 and Figure 19 As can be seen from the image, this embodiment has a hollow cylindrical heating device 50.5., in which a container (not shown) for containing components can be arranged within an upwardly open cavity 50.5.a. The container may contain an insert with a rotatable magnetic stirrer and a stirring cage 52.6., wherein the stirring cage 52.6., together with other elements of the insert, forms a... Figures 20 to 22 As shown in the diagram. Below the heating device 50.5 and the four-head scale 50.11, eight electromagnetic coils 50.7 are arranged in a ring (see...). Figure 19 These electromagnetic coils 50.7, through their respective switching / activation, cause a magnetic stirrer arranged in the container and equipped with a permanent magnet to rotate, replacing the rotating permanent magnet driven by an electric motor. Furthermore, the device provides a cuboid housing 53 for accommodating a voltage source (e.g., two batteries) and LED indicator lights 50.4. A ribbed cooling element 55 is provided at the upper end of the heating device 50.5, wherein this cooling element 55 prevents heat generated by the heating device 50.5 from being transferred to the housing of the device (not shown) used for producing personal care products, cosmetics, or household products.

[0061] Figures 20 to 22A fourth embodiment of an apparatus for producing personal care products, cosmetics, or household products is shown, comprising a stirring cage 52.6. The stirring cage 52.6. is integrally formed with a connecting strut 52.2.d projecting upward from the stirring cage 52.6. and an annular retaining element 52.1. connected to the connecting strut 52.2.d at the top, the annular retaining element 52.1. having a handle 52.1.b. The stirring cage 52.6. of this embodiment includes spoke-shaped struts 52.6.c and a through-hole 52.6.d disposed therebetween. Furthermore, the stirring cage 52.6. has an edge 52.6.a that facilitates the homogenization, dispersion, emulsification, softening, melting, and / or pulverization of components added to the container. The stirring cage 52.6. does not include a protruding spindle in the central portion of the connecting spoke-shaped struts 52.6.c, which could serve as a bearing element for the rotational movement of a magnetic stirrer within the stirring cage 52.6. In this embodiment of the stirring cage 52.6, the magnetic stirrer rotates freely under the drive of the coil 50.7, i.e., without a pivot bearing (see...). Figure 19 The stirring cage 52.6. has a fixed or variable axis of rotation. On the surface of the stirring cage 52.6. facing the magnetic stirrer, the stirring cage 52.6. at least partially includes a corrugated or bumped surface structure 52.6.e, which causes the magnetic stirrer to adhere / force-lock to the surface of the stirring cage 52.6. to generate rotation of the stirring cage 52.6. The surface structure 52.6.e is arranged, for example, on the spoke-shaped support 52.6.c and the central portion connecting the support (see...). Figure 20 The retaining element 52.1 includes a flange 52.1.a, which rests on the top side of the container. The handle 52.1.b has a groove, similar to the fourth embodiment, which engages with a locking element to... Figures 20 to 22 The integrated assembly shown (e.g., including the stirring cage 52.6, connecting support 52.2.d, and retaining element 52.1.) is either fixed together to the container or allows them to rotate freely together. Rotation of the integrated assembly is achieved by a surface structure 52.6.e located on the surface of the stirring cage 52.6. facing the magnetic stirrer. As described above, the speed of this rotation can be detected by a proximity sensor 57 (see [link to sensor]). Figure 18 The rotation of the integrated assembly is further defined by corresponding markings on the bottom side of the stirring cage 52.6. and the handle 52.1.b, and is controlled or adjusted by an internal or external computing unit (not shown). In one embodiment, control or adjustment may be provided such that the rotation speed reaches a maximum value of, for example, 250 rpm. The rotation of the integrated assembly is also achieved by the stirring cage 52.6. including a disc-shaped protrusion 52.6.f on its bottom side (i.e., the side facing the bottom of the container) (see...). Figure 21 and Figure 22The end face of the disc-shaped protrusion 52.6.f is flat. The flat design of the end face facing the bottom of the container reduces friction between the bottom of the container and the stirring cage 52.6., thus supporting the rotational movement of the integral assembly within the container.

[0062] Furthermore, curved ribs or webs 52.7 are provided on the inner side of each connecting strut 52.2.d. (See also: [link to specific details]) Figure 21 The rib or web 52.7. protrudes from the inside of the connecting strut 52.2.d. The rib 52.7. has a concave shape in the direction of rotation (here: counterclockwise), which causes the components in the container to be pressed toward the direction of the magnetic stirrer and stirring cage 52.6. (i.e. downward), so that they can be handled better.

[0063] Due to the construction of the insert with a stirring cage and a magnetic stirrer, minimal loss of component proportions was observed. Therefore, the above-described apparatus and method are advantageously suited for preparing small quantities of personal care products, cosmetics, or household products. Furthermore, the apparatus and method are easy to operate.
