Description

State of the art

[0001] The invention relates to a device for removing liquids from a bag-in-box bag according to claim 1.

[0002] Bag-in-box solutions are well-known in the art and offer practical packaging for larger quantities of liquids. They are particularly suitable for fruit juices, wine, oil, or other consumable liquids. The bag-in-box bag provides a stable, lightweight, and flexible packaging for the liquid, ensuring its long-lasting storage.

[0003] Conventional devices or boxes for holding the bag-in-box usually consist of a rectangular cardboard box. The box often has an opening designed to allow a stopcock for the bag-in-box to protrude from the box when the bag-in-box is inserted into the box. Figure 11The present drawings show such a device according to the prior art by way of example. Typically, the box in the prior art comprises a flat and straight support base for the bag-in-box. The simple rectangular geometry of the box with the flat support base does allow the bag-in-box to be easily inserted and removed from the box and offers practical stacking options, but it has significant disadvantages when it comes to removing liquid. When the bag-in-box is inserted into the box, it is not possible to empty it completely, so that a residue of liquid always remains in the bag. In order to empty the bag completely, a user must first remove the bag-in-box from the box and manually squeeze the remaining liquid out of the bag. This is very cumbersome and time-consuming for the user.

[0004] The object of the present invention is, in particular, to provide a generic device for withdrawing liquids from a bag-in-box bag with improved properties in terms of user comfort and efficiency. This object is achieved according to the invention by the features of claim 1, while advantageous embodiments and further developments of the invention can be found in the subclaims. Advantages of the invention

[0005] According to the invention, a device for removing liquids from a bag-in-box bag is proposed, comprising a housing comprising at least one side wall which, in a state of use, is aligned at least substantially in the vertical direction, delimits an interior of the housing in sections and defines an upper housing opening, via which the bag-in-box bag can be inserted in the vertical direction into the interior of the housing, and comprising an intermediate floor which is arranged in the interior and forms a support surface for the bag-in-box bag, wherein the side wall has a lateral housing opening through which a dosing unit of the bag-in-box bag can be led out of the interior at least partially, wherein the support surface has an inclined central section, wherein an imaginary straight line running along a main extension direction of the inclined central section,runs through the side housing opening and forms an angle of less than 90° with the vertical direction.

[0006] Such a design makes it possible to remove liquid from a bag-in-box more efficient, user-friendly, and easier. Advantageously, the proposed device enables at least substantially complete removal of liquid from the bag-in-box. This increases user comfort and eliminates the need for laborious separate emptying of the bag-in-box when not in use with the device. By means of the inventive design of the inclined central section, the guidance of liquid to the dosing unit of the bag-in-box can be made more uniform and efficient in the application state, so that the user can completely empty the bag-in-box of liquid by actuating the dosing unit. Furthermore, the efficiency of the device in terms of use, application, and application can be increased.Furthermore, resource efficiency can be advantageously increased by enabling at least essentially complete removal of liquid from the bag-in-box bag, even for those users who have previously disposed of bag-in-box bags with residual liquid because separate emptying was too laborious, now easily and without any additional effort. Furthermore, resource efficiency can be increased in that the device can be refilled multiple times with new bag-in-box bags. Advantageously, the user can only purchase the bag-in-box bag for refilling, without the box previously known in the prior art. This makes it possible to provide a particularly sustainable device. Furthermore, packaging materials and costs can be saved, and a resource-saving bag-in-box system can be enabled.

[0007] In particular, the device and the bag-in-box bag are part of a bag-in-box bag system. The bag-in-box bag can be designed to hold larger quantities of liquids, for example at least three, advantageously at least five, particularly advantageously at least ten liters of liquid, and to store them leak-proof. The liquid can be, for example, fruit juice, wine, oil, or other consumable liquids. Preferably, the liquid is edible / intended for consumption. Alternatively, non-edible liquids such as soap, detergents, or cleaning agents are also conceivable. In particular, the device is intended to hold the bag-in-box bag at least partially, preferably completely. The bag-in-box bag can be inserted / inserted into the housing in the vertical direction via the upper housing opening.The bag-in-box can preferably be inserted into the housing without damage and removed from the housing again without damage, particularly preferably without tools. For use, a user can insert the bag-in-box bag into the interior of the housing via the upper housing opening in the vertical direction and position it in the interior. In an inserted state, the bag-in-box bag, in particular at least one bag unit of the bag-in-box bag, can be arranged at least partially, preferably completely, in the interior of the housing. In particular, the bag unit of the bag-in-box bag is intended to absorb liquid and store it in a leak-proof manner. In particular, the inserted state of the bag-in-box bag prevails in the use state. The bag-in-box bag, in particular the bag unit, can advantageously be positioned on the intermediate floor.The intermediate floor preferably delimits the interior of the housing at least partially or at least largely downwards, viewed in the vertical direction. The intermediate floor can be part of the housing and formed integrally, in particular in one piece, with at least the side wall. Preferably, the bag-in-box bag, in particular the bag unit, rests on the intermediate floor, in particular the support surface, in the used state and makes direct contact with it. The term "largely" in this document is understood to mean at least 55%, advantageously at least 65%, preferably at least 75%, particularly preferably at least 85%, and particularly advantageously at most 95% of an area, volume, and / or mass fraction.

[0008] In particular, the dosing unit is arranged on the bag unit and is intended to dose the withdrawal of liquid from the bag unit. The dosing unit can have at least one tap, in particular a shut-off tap, which can be actuated by the user to withdraw the liquid from the bag unit. When the bag-in-box bag is inserted into the housing, the dosing unit, in particular at least the tap, can be led out of the interior at least partially, preferably at least to a large extent, through the lateral housing opening. Preferably, in the inserted state, in particular the application state, the bag unit is arranged entirely in the housing, in particular the interior, and at least the tap of the dosing unit is arranged at least partially outside the housing, in particular the interior.

[0009] The device can have a cover unit which is intended to cover the upper housing opening at least partially, at least largely or completely. When the bag-in-box bag is inserted, the cover unit can close the upper housing opening and thus cover at least the bag unit of the bag-in-box bag at least partially, preferably completely, in the direction of the upper housing opening. In particular, the cover unit is designed as a lid. The cover unit could be fastened to the housing by means of a positive and / or non-positive connection, such as a snap-in connection and / or plug-in connection and / or rotary connection and / or clamp connection and / or Velcro connection. For example, the cover unit can be arranged on the housing by means of a hinge and thus mounted so as to be pivotable relative to the upper housing opening.Alternatively, the cover unit can be designed without any connecting units to the housing and can be removed and replaced by the user. In addition to covering the bag-in-box bag in its inserted state, the cover unit enables convenient and user-friendly stacking of the device.

[0010] The device is preferably a container or a box. The housing can be made at least partially, at least largely, or entirely from a mineral, for example, glass or stone, and / or from a renewable raw material, such as wood, and / or from a fibrous material, for example, paper or cardboard, and / or from plastic and / or from metal, such as stainless steel, and / or from a composite material. The housing can be formed in one piece, preferably in one piece. "Integral" is understood to mean at least materially connected, for example, by an adhesive process, an injection molding process, and / or a welding process, and / or another process deemed appropriate by a person skilled in the art. "One-piece" is understood to mean formed in one piece.Preferably, this one piece is produced from a single blank, a mass and / or a casting, particularly preferably in an injection molding process and / or in a stamping process and / or in a sheet metal bending process and / or in a printing process, for example a 3D printing process, and / or another process that appears appropriate to the person skilled in the art.

[0011] For user-friendly handling, the device can have at least one handle unit on the housing. The handle unit could be an element formed separately from the housing and arranged on at least one side wall, in particular the aforementioned side wall, of the housing. Alternatively, the handle unit can be a handle opening in the side wall of the housing. Preferably, the device has at least two handle units, each arranged on opposite sides of the housing.

[0012] It would be conceivable for the housing to have a round or oval geometry when viewed in the circumferential direction. The housing could, for example, be cylindrical. Preferably, the housing has an angular geometry when viewed in the circumferential direction. For example, the housing can have at least four, six, or eight corners when viewed in the circumferential direction. The side wall can define precisely one side of the housing, which, when viewed in the circumferential direction of the housing, extends in particular between two corners of the housing. Alternatively, the side wall could extend over the entire lateral circumference of the housing.

[0013] In the use state, the housing is preferably placed on a surface and stored upright, for example, on a table, shelf, or floor. In particular, in the use state, a vertical direction of the housing extends parallel to the vertical direction. Preferably, the side wall is aligned parallel to the vertical direction in the use state. However, it would also be conceivable for the side wall to be aligned obliquely to the vertical direction in the use state. An intersection angle between the vertical direction and a main extension direction of the side wall could be at least 5°, advantageously at least 10°, and preferably at most 45°.

[0014] According to a general definition known to those skilled in the art, the vertical direction is the local direction of gravitational acceleration, which always points downward in the direction of the gravitational force. Viewed in the vertical direction of the housing, an upper edge of the side wall at least partially defines the upper housing opening. If the housing has multiple side walls, for example, at least two or four side walls, the upper edges of the side walls can jointly define the upper housing opening, at least partially or completely, viewed in the vertical direction of the housing.

[0015] The lateral housing opening could be angular. Advantageously, the lateral housing opening has a circular or oval shape. Preferably, the lateral housing opening has at least one passage area and one holding area. The passage area can have a round, circular shape, wherein a diameter of the passage area is advantageously larger than a diameter of the dosing unit. Preferably, the dosing unit has a fastening element provided for attaching the tap to the lateral housing opening. In particular, the diameter of the passage area is larger than a diameter of the fastening element.

[0016] When inserting the bag-in-box bag into the device, the dosing unit can be at least partially guided out of the interior through the feed-through region. In particular, the holding region directly borders the feed-through region and, viewed in the vertical direction and particularly in the application state, is arranged below the feed-through region. The holding region can have a round, circular geometry, wherein a diameter of the holding region is advantageously smaller than a diameter of the dosing unit, in particular of the fastening element. Furthermore, the diameter of the holding region can be smaller than the diameter of the feed-through region. The diameter of the holding region can be at least 5%, advantageously at least 10%, and particularly advantageously at least 25% smaller than the diameter of the feed-through region.Particularly advantageously, the holding region and the feed-through region form two circles arranged next to one another and at least partially overlapping. In the inserted state, the dosing unit can be arranged at least partially in the holding region. In particular, in the inserted state, the dosing unit is inserted / arranged / fixed in the holding region with a form-fitting fit. The fastening element preferably has a first fastening section and a second fastening section opposite the first fastening section and running parallel thereto. Particularly preferably, the diameter of the holding region is smaller than a diameter of the first fastening section and the second fastening section of the fastening element.In the inserted state, the first fastening section can be arranged outside the interior, specifically on an outer side of the side wall, and the second fastening section can be arranged inside the interior, specifically on an inner side of the side wall. Preferably, in the inserted state, the holding region of the lateral housing opening is located between the first fastening section and the second fastening section of the fastening element.

[0017] It would also be conceivable for the device to comprise a fixing unit designed to additionally fix the dosing unit in the lateral housing opening, particularly in the holding area, by means of a positive and / or non-positive connection. The fixing unit can, for example, be designed to fix the dosing unit in the lateral housing opening by means of a snap-in connection, a sliding connection, a clamping connection, and / or a plug-in connection, and / or the like.

[0018] The angle of intersection of the imaginary straight line and the perpendicular direction can be at least 80°, advantageously at least 70°, and particularly advantageously at least 60°. The imaginary straight line running along the main extension direction of the inclined central section could run through the passage area of the lateral housing opening. Preferably, the imaginary straight line runs through the holding area of the lateral housing opening. A "main extension direction" of an object is understood here to mean a direction that runs parallel to a longest edge of a smallest geometric cuboid that just completely encloses the object. In particular, the main extension direction of the object extends within a main extension plane of the object.In this context, a "main extension plane" of an object is understood to mean a plane that is aligned parallel to the largest side surface of the smallest imaginary cuboid that just completely encloses the object, and in particular, passes through the center of the cuboid. Furthermore, "intended" here and below is understood to mean specially designed, configured, designed, and / or equipped.

[0019] It would be conceivable for the intermediate floor to completely delimit the interior of the housing at the bottom, viewed in the vertical direction. The intermediate floor could extend over the entire floor area of the housing in the interior. However, in order to be able to provide a functionally reliable arrangement of the bag-in-box bag in the device with the proposed embodiment, to increase user comfort and to advantageously position the dosing unit of the bag-in-box bag efficiently and functionally reliably on the device, in particular the lateral housing opening, it is proposed that the intermediate floor have a recess which is arranged between the inclined central section and the lateral housing opening. By means of the recess, the dosing unit can be guided at least partially through the lateral housing opening and functionally reliably fastened to it.In particular, the recess extends, viewed perpendicular to the vertical direction, between the inclined central section and the lateral housing opening, in particular at least the passage area of the lateral housing opening. A distance of the recess between the lateral housing opening and the inclined central section, in particular a depth extension of the recess, can be at least 35 mm, advantageously at least 45 mm, particularly advantageously at least 55 mm, and preferably at most 80 mm, particularly preferably at most 70 mm.

[0020] In order to further improve the arrangement of the dosing unit of the bag-in-box bag at the lateral housing opening and to make it more stable, the device can have a fixing element on the inside of the side wall of the housing. This can advantageously prevent the dosing unit from tipping over or falling out when inserted. The fixing element can be arranged at least in sections at the lateral housing opening on the inside of the side wall. In particular, the inside of the side wall faces the interior. The fixing element could extend on the inside of the side wall along the feed-through area and / or the holding area. Preferably, the fixing element extends at least in sections along the holding area. Particularly preferably, the fixing element extends along an entire circumference of the holding area on the inside of the side wall in the form of a circular section.In particular, the fixing element has a consistent material thickness. In particular, the fixing element is intended to fix the dosing unit to the lateral housing opening in the inserted state, in particular the application state, and to prevent the dosing unit from tipping over. Preferably, the second fastening section of the fastening element of the dosing unit contacts the fixing element on the inside of the side wall in the inserted state.

[0021] It is further proposed that the support surface have at least a first inclined wing section and at least a second inclined wing section, wherein the main extension planes of the two inclined wing sections have a common intersection line which runs at least substantially parallel to the imaginary straight line. This makes it possible to optimize the support and reception of the bag-in-box bag in the device and further improve the design of the device. In addition, by means of the wing sections designed according to the invention, optimal liquid guidance towards the inclined central section can be enabled and thus the efficiency in removing liquid from the bag-in-box bag can be increased, which in turn increases user comfort. The intersection line is a line of intersection, known to those skilled in the art by definition, of two planes that are not parallel to one another.Preferably, the intersection line lies below the imaginary line, viewed in the vertical direction. The intersection line and the imaginary line running at least "essentially parallel" to each other is understood here to mean that the directions of the intersection line and the imaginary line deviate by less than 5°, advantageously less than 3°, and particularly advantageously less than 1°.

[0022] Furthermore, in this document, numerals such as "first" and "second," which precede certain terms, serve only to distinguish between objects and / or to assign objects to one another and do not imply a total number and / or ranking of the objects. In particular, a "second" object does not necessarily imply the presence of a "first" object.

[0023] In order to further improve the insertion and arrangement of the dosing unit of the bag-in-box bag at the lateral housing opening and to increase the efficiency with regard to the removal of liquid from the bag-in-box bag in the application state, it is proposed that the recess be defined at least in sections by the inclined wing sections. In particular, the inclined central cut and the two inclined wing sections together define the recess. Preferably, the inclined central cut, the two inclined wing sections and the side wall together delimit the recess. A distance of the recess between the first inclined wing section and the second inclined wing section, in particular a width extension of the recess, can be at least 60 mm, advantageously at least 70 mm, particularly advantageously at least 80 mm and preferably at most 120 mm, particularly preferably at most 100 mm.

[0024] Furthermore, it is proposed that the inclined central section be arranged between the inclined wing sections and contact them in sections. This can increase the efficiency of fluid flow and improve the design of the intermediate floor. Furthermore, the adjacent wing sections can ensure optimal fluid flow toward the inclined central section, thus optimizing user-friendliness and comfort when removing fluid from the bag-in-box.

[0025] In particular, the inclined central section directly contacts the two inclined wing sections. "Direct" contact should be understood to mean that no further objects, components and / or structural units are arranged between a first object and a second object, which are in direct contact. Preferably, the direct contact is direct surface contact between a surface of the first object and a surface of the second object. The inclined central section could contact the inclined wing sections along a distance which corresponds to at least 30%, advantageously at least 50% and particularly advantageously at least 80% of its main extension. Preferably, the inclined central section contacts the two inclined wing sections equally along its entire main extension.Particularly preferably, the inclined central section is formed integrally, in particular in one piece, with the two inclined wing sections.

[0026] It is also proposed that the support surface have at least one inclined front section which contacts the side wall and has a main extension plane which forms an angle of greater than 90° with the vertical direction. This allows a design of the device, in particular of the intermediate base, to be further optimized and efficiency with regard to liquid guidance for removing liquid from the bag-in-box bag to be increased. Furthermore, by means of at least the front section designed according to the invention, liquid can be efficiently guided from a front edge region of the bag-in-box bag in the use state to the dosing unit, thus enabling at least substantially complete removal of liquid from the bag-in-box bag.

[0027] Advantageously, the front section directly contacts the side wall. The angle between the main extension plane of the inclined front section and the vertical direction can be at least 100°, advantageously at least 110°, preferably at least 120°, and particularly advantageously at least 140°. In particular, said angle is the opposite angle to an intersection angle of the main extension plane of the inclined front section and the vertical direction. In particular, said front section is a first inclined front section. The support surface can have further front sections, specifically at least a second inclined front section. The first inclined front section can, in particular on a side opposite the side turn of the first inclined front section, preferably directly contact the first inclined wing section.Preferably, the second inclined front section is structurally identical to the first inclined front section, so that the explanations and descriptions for the first inclined front section can also be applied to the second inclined front section. The second inclined front section can contact the side wall and have a main extension plane which forms an angle of greater than 90° with the vertical direction. Particularly preferably, both angles of the first and second inclined front sections have at least substantially identical values. Furthermore, the first inclined front section can contact the second inclined wing section, preferably directly, in particular on a side of the second inclined front section opposite the side wall.In this document, "at least substantially" is understood to mean that a deviation from a predetermined value and / or direction and / or orientation is less than 10%, preferably less than 5%, and particularly preferably less than 2% of the predetermined value and / or direction and / or orientation.

[0028] In order to further improve the design of the device and the liquid guide for removing liquid from the bag-in-box bag, it is proposed that the main extension plane of the inclined front section and the main extension plane of the first inclined wing section have a common intersection line and enclose an angle of inclination of greater than 90°. This allows liquid to be efficiently guided between the inclined front section and wing section to the dosing unit, enabling faster removal of liquid from the bag-in-box bag. In particular, the angle of inclination is the opposite angle to the angle of intersection of the main extension plane of the inclined front section, in particular of the first inclined front section, and the main extension plane of the first inclined wing section.The angle of inclination of the main extension plane of the inclined front section, in particular of the first inclined front section, and the main extension plane of the first inclined wing section can be at least 110°, advantageously at least 120°, preferably at least 140°, and particularly advantageously at least 150°. Advantageously, the main extension plane of the second inclined front section and the main extension plane of the second inclined wing section have a common intersection line and enclose an angle of inclination of greater than 90°. Particularly preferably, both angles of inclination between the main extension plane of the first inclined front section and the main extension plane of the first inclined wing section, as well as between the main extension plane of the second inclined front section and the main extension plane of the second inclined wing section, have at least substantially identical values.

[0029] It is also proposed that the inclined central section have a trough-shaped depression along its main extension direction. This makes it easier and more efficient to guide liquid in the use state. Advantageously, the liquid in the Bax-in-Box bag, in particular in the bag unit of the Bax-in-Box bag, can thus be guided in a controlled manner to the lateral housing opening, in particular the dosing unit of the Bax-in-Box bag, so that a liquid backup or blockage in the liquid flow can be advantageously prevented. Viewed in the main extension direction of the inclined central section, the trough-shaped depression could only extend in sections along the main extension of the inclined central section. Preferably, the trough-shaped depression extends along the entire main extension of the inclined central section.The trough-shaped depression can form a kind of channel for the liquid. The trough-shaped depression can have a curvature whose radius of curvature is at least 5 mm, advantageously at least 10 mm, and preferably at least 20 mm.

[0030] It is further proposed that the imaginary straight line lie in an imaginary plane running parallel to the perpendicular direction, which divides the interior into two equal parts. To increase efficiency with regard to design, manufacture, and handling of the device, it is also proposed that the imaginary plane be a plane of symmetry. This can increase manufacturing, design, and cost efficiency and, in particular, reduce manufacturing effort. At the same time, it is advantageous to enable designs of the device that are particularly visually appealing to the user. Due to the symmetry, a uniform withdrawal of liquid from the bag-in-box can also be ensured.

[0031] Furthermore, it is proposed that the device include a drip tray for placement on the side wall below the lateral housing opening, particularly when viewed in the vertical direction. This improves user comfort and facilitates handling. Advantageously, unwanted dripping when withdrawing liquid from the bag-in-box bag can be collected below the dosing unit, thus reducing, and preferably preventing, contamination of a surface. Furthermore, the drip tray can provide a place for a container, thus enabling the user to withdraw liquid with one hand.

[0032] The drip tray is preferably located below the dosing unit, viewed in the vertical direction and in the inserted state of the bag-in-box bag. The drip tray can be reversibly arranged on the side wall and preferably removable from the side wall without causing damage, for example for cleaning purposes and / or emptying. A positive and / or non-positive connection between the drip tray and the side wall would be conceivable, such as a plug-in, snap-in and / or clamp connection. In particular, the drip tray is intended to collect, in particular, unwanted liquid escaping from the dosing unit. The drip tray can have at least one drip plate, which can be intended to form a support surface for a container, such as a glass or a cup.When withdrawing liquid from the bag-in-box in the application state, the user could position the container on the drip tray, in particular the drip plate. The drip plate is preferably located below the dosing unit, viewed vertically.

[0033] It is also proposed that, viewed along the vertical direction, a distance between the lateral housing opening and a bottom edge of the housing corresponds at least to a distance between the lateral housing opening and the upper housing opening. This can increase user comfort and make handling when using the device and removing liquid from the bag-in-box bag more convenient and user-friendly. This advantageously makes it possible to position a container, for example a glass or a cup, below the lateral housing opening in the use state. This allows the liquid to be poured directly from the bag-in-box bag into the container in the use state, with the container itself being supported upright on a base.The distance between the lateral housing opening, in particular the holding region, and the bottom edge of the housing and the distance between the lateral housing opening, in particular the feed-through region, and the upper housing opening can have at least substantially the same value. Preferably, the distance between the lateral housing opening and the bottom edge of the housing is greater than the distance between the lateral housing opening and the upper housing opening, in particular by at least 5%, advantageously by at least 10%, and particularly advantageously by at least 15%. The distance between the lateral housing opening and the bottom edge of the housing could be at least 120 mm, preferably at least 150 mm, preferably at least 180 mm, and particularly preferably at least 200 mm.

[0034] The device for extracting liquids from a bag-in-box bag is not intended to be limited to the application and embodiment described above. In particular, the device may have a number of individual elements, components, and / or units that differs from the number stated herein to fulfill a function described herein. Furthermore, in the value ranges / value scales specified in this document, values within the stated limits / scaled values are also considered disclosed and can be used arbitrarily. drawing

In this exemplary embodiment, the housing 14a has at least two handle units 84a, which are arranged on opposite sides of the housing 14a (not explicitly shown).

[0038] Viewed in the vertical direction 90a, the housing 14a has an upper housing opening 22a. At least the side wall 16a defines the upper housing opening 22a. The upper housing opening 22a allows access to the interior 20a of the housing 14a. The upper housing opening 22a of the housing 14a is in Figure 1covered with a cover unit 80a of the device 10a. The cover unit 80a could cover only a portion of the upper housing opening 22a. In the present case, the cover unit 80a completely covers the upper housing opening 22a. In this exemplary embodiment, the cover unit 80a is designed to be completely detachable from the housing 14a and is free of hinges or other connecting units. To insert the bag-in-box bag 12a into the device 10a, the cover unit 80a can be removed from the upper housing opening 22a by a user, so that the bag-in-box bag 12a can be inserted through the upper housing opening 22a into the interior space 20a of the housing 14a in the vertical direction 18a. Furthermore, the bag-in-box bag 12a can be inserted into the housing 14a without destruction and removed from the housing 14a without destruction, and without tools.

[0039] In Figure 21 shows an inserted state of the bag-in-box bag 12a in the device 10a, wherein the cover unit 80a has been omitted for clarity. The bag-in-box bag 12a has a bag unit 82a. In the inserted state, specifically in the use state, the bag unit 82a is arranged in the interior space 20a. In the present case, the bag unit 82a is arranged completely in the interior space 20a in the use state. In the use state, the bag unit 82a contacts the intermediate floor 26a and rests thereon. For dosing a liquid withdrawal, the bag-in-box bag 12a has a dosing unit 30a. In the present case, the dosing unit 30a is designed as a shut-off valve and is intended to be operated by the user when withdrawing the liquid.

[0040] In the inserted state, the dosing unit 30a is arranged at least partially outside the interior space 20a (cf. Figure 2). The side wall 16a has a lateral housing opening 24a through which the dosing unit 30a can be at least partially led out of the interior 20a. The lateral housing opening 24a has a lead-through region 86a and a holding region 88a. The lead-through region 86a has a round, circular geometry, wherein a diameter of the lead-through region 86a is greater than a diameter of the dosing unit 30a. When the bag-in-box bag 12a is inserted into the device 10a, the dosing unit 30a can be led out of the interior 20a through the lead-through region 86a. The holding region 88a directly borders on the lead-through region 86a and, viewed in the vertical direction 18a, is arranged below the lead-through region 86a (cf. Figures 1 and 2). The holding area 88a has a round, circular geometry, wherein a diameter of the holding area 88a is smaller than the diameter of the dosing unit 30a. Furthermore, the diameter of the holding area 88a is smaller than the diameter of the feed-through area 86a. In the present case, the lateral housing opening has a keyhole-like shape. In the inserted state, the dosing unit 30a is at least partially arranged in the holding area 88a. In the present case, the dosing unit 30a is at least partially inserted in a form-fitting manner in the holding area 88a. It would be conceivable for the device 10a to comprise a fixing unit which is provided to additionally fix the dosing unit 30a in the holding area 88a by means of a form-fitting and / or force-fitting connection.

[0041] To illustrate a design of the interior 20a, the Figure 3A cutaway view of the housing 14a. The device 10a has an intermediate floor 26a, which is arranged in the interior space 20a. The intermediate floor 26a delimits the interior space 20a at least partially downwards, as viewed in the vertical direction 18a. The intermediate floor 26a forms a support surface 28a for the bag-in-box bag 12a. In the inserted state, the bag-in-box bag 12a, specifically the bag unit 82a, is arranged on the support surface 28a and makes direct contact with it.

[0042] Based on the Figures 3 to 8 The geometry and design of the intermediate floor 26a will be explained in more detail below. In particular, the Figure 4 shows a detailed view of the intermediate floor 26a.

[0043] The support surface 28a of the intermediate base 26a has an inclined central section 32a. An imaginary straight line 34a running along a main extension direction of the inclined central section 32a runs through the lateral housing opening 24a and forms an intersection angle 36a of less than 90° with the vertical direction 18a (cf. Figures 7 and 8 ). In the present exemplary embodiment, the intersection angle 36a is at least 70°. The imaginary straight line 34a runs through the holding area 88a of the lateral housing opening 24a (cf. Figures 7 and 8 ). For efficient fluid guidance, the inclined central section 32a has a trough-shaped depression 60a along its main extension direction (cf. Figures 3 , 4 and 6). This makes it easier to guide liquid in the application state, and the liquid in the bag unit 82a of the Bax-in-Box bag 12a can be guided in a controlled manner to the lateral housing opening 24a, specifically the dosing unit 30a of the Bax-in-Box bag 12a, so that a build-up of liquid or a blockage in the liquid flow can be prevented.

[0044] Figure 4 illustrates that the trough-shaped depression 60a, viewed in the main extension direction of the inclined central section 32a, extends along the entire main extension of the inclined central section 32a. Figure 3It is clear that the imaginary straight line 34a lies in an imaginary plane 62a running parallel to the perpendicular direction 18a. This plane 62a divides the interior space 20a into two equal parts. In this case, the imaginary plane 62a is a plane of symmetry. The interior space 20a is symmetrical, in particular mirror-symmetrical, with respect to the plane 62a.

[0045] Furthermore, the support surface 28a has at least one first inclined wing section 40a and at least one second inclined wing section 42a. The inclined central section 32a is arranged between the inclined wing sections 40a, 42a and contacts them in sections (see. Figures 3 and 4 ). In the present embodiment, the central section 32a, viewed along the main extension direction of the central section 32a, contacts the two inclined wing sections 40a, 42a completely along its entire main extension.

[0046] In Figure 4 It is schematically shown that the main extension planes of the two inclined wing sections 40a, 42a have a common intersection line 44a, which runs parallel to the imaginary line 34a. Viewed in the vertical direction 18a, the intersection line 44a is positioned below the imaginary line 34a.

[0047] The support surface 28a has at least one inclined front section 46a, which contacts the side wall 16a (cf. Figures 3 , 4 , 6 and 7 ). The front section 46a is referred to herein as the first inclined front section 46a. Figure 7shows that a main extension plane of the first inclined front section 46a forms an angle 52a of greater than 90° with the vertical direction 18a. In this case, the angle 52a is at least 114°. The first inclined front section 46a directly contacts the side wall 16a. Furthermore, the first inclined front section 46a directly contacts the first inclined wing section 40a. Figures 7 and 8 illustrate that the main extension plane of the first inclined front section 46a and the main extension plane of the first inclined wing section 40a have a common intersection line 54a, enclosing an angle of inclination 56a of greater than 90°. In this exemplary embodiment, the angle of inclination is at least 140°.

[0048] In this case, the support surface 28a also has at least a second inclined front section 48a. In this embodiment, the second inclined front section 48a is structurally identical to the first inclined front section 46a, so that the explanations and descriptions for the first inclined front section 46a can also be applied to the second inclined front section 48a. The second inclined front section 48a directly contacts the side wall 16a and the second inclined wing section 42a (cf. Figure 5 ).

[0049] For more comfortable handling, a user-friendly, and more efficient arrangement of the dosing unit 30a in the device, specifically at the lateral housing opening 24a, the intermediate base 24a has a recess 38a arranged between the inclined central section 32a and the lateral housing opening 24a. Viewed perpendicular to the vertical direction 18a, the recess 38a extends between the inclined central section 32a and the lateral housing opening 24a, specifically at least the feedthrough area 86a. In the present case, a distance of the recess 38a between the lateral housing opening 24a and the inclined central section 32a, specifically a depth extension of the recess 38a, is at least 45 mm. Furthermore, the recess 38a is defined at least in sections by the inclined wing sections 40a, 42a. Figure 5shows that the inclined central section 32a and the two inclined wing sections 40a, 42a together define the recess 38a, which is also delimited by the side wall 16a. In the present case, the distance of the recess 38a between the first inclined wing section 40a and the second inclined wing section 42a, namely the width of the recess 38a, is at least 70 mm.

[0050] In order to further improve the arrangement of the dosing unit 30a at the lateral housing opening 24a and to make it more stable, the device 10a has a fixing element 92a on an inner side of the side wall 16a. The fixing element 92a is arranged at least in sections at the lateral housing opening 24a on the inner side of the side wall 16a. The inner side of the side wall 16a faces the interior space 20a. The fixing element 92a extends at least in sections along the holding area 88a. In the present case, the fixing element 92a extends along an entire circumference of the holding area 88a on the inner side of the side wall 16a in the form of a circular segment and has a constant material thickness. In the inserted state, a first fixing section of a fixing element (without reference symbol) of the dosing unit 30a presses against an outer side of the side wall 16a.Furthermore, in the inserted state, a second fastening section of the fastening element (without reference symbol) of the dosing unit 30a presses against the inside of the side wall 16a, specifically against the fixing element 92a. This prevents the dosing unit 30a from tipping over or falling out, thus increasing user comfort.

[0051] In the Figures 8 and 9 A further embodiment of the invention is shown. The following descriptions are essentially limited to the differences between the embodiments, whereby with regard to the same components, features and functions, reference is made to the description of the embodiment of the Figures 1 to 7 To distinguish the embodiments, the letter "a" in the reference numerals of the embodiment in the Figures 1 to 7 by the letter "b" in the reference numerals of the embodiment of the Figures 8 to 9 replaced.

[0052] Figure 8 shows a device 10b for withdrawing liquids from a bag-in-box bag in an alternative embodiment. The device 10b has a housing 14b. The housing 14b comprises at least one side wall 16b, which, in a use state, is oriented in the vertical direction 18b and partially delimits an interior space 20b of the housing 14b (cf. Figure 9 ). Furthermore, the housing 14b has an upper housing opening 22a, through which the bag-in-box bag can be inserted in the vertical direction 18b into the interior 20b of the housing 14b. In Figure 8 A cover unit 80b of the device 10b is shown, which covers the upper housing opening 22a. The cover unit 80b is reversibly detachable from the housing 14b and can be arranged on the housing 14b. Figure 9clarifies with the sectional representation of the device 10b that the interior 20b, namely an intermediate floor 26b of the device 10b with its support surface 28b analogous to the intermediate floor 26a with support surface 28a according to the description in the embodiment "a" according to the Figures 1 to 7 is designed.

[0053] In contrast to exemplary embodiment "a", a distance 66b, viewed in the vertical direction 18b, between the lateral housing opening 24b and a bottom edge 68b of the housing 14b corresponds at least to a distance 70b between the lateral housing opening 24b and the upper housing opening 22b. In the present case, the distance 66b extends between the bottom edge 68b and a holding region 88b of the lateral housing opening 24b. The distance 70b extends between the upper housing opening 22b and a passage region 86b of the lateral housing opening 24b. The distance 66b and the distance 70b could have the same value. In this exemplary embodiment, the distance 66b is greater than the distance 70b. In the present case, the distance 66b is at least 180 mm. The distance 66b is at least 5% greater than the distance 70b. This makes it possible to position a vessel, for example a glass or a cup, below the side housing opening 24b in the application state.This means that in the application state, the liquid can be filled directly from the bag-in-box bag into the container, with the container itself being stored upright on a base.

[0054] To further increase user-friendliness and, in particular, to catch unwanted dripping when removing liquid from the bag-in-box bag and thus prevent contamination of a surface, the device 10b has a drip tray 64b for arrangement on the side wall 16b below the lateral housing opening 24b. The drip tray 64b can be reversibly arranged on the side wall 16b and can be removed from the side wall 16b without causing damage, for example for cleaning purposes. To further increase user comfort and enable the user to remove liquid with one hand, the drip tray 64b in the present embodiment has at least one drip plate which forms a support surface for the container. The container can thus be positioned by the user on the drip tray 64b below the lateral housing opening 24b, as viewed in the vertical direction 18b. Reference symbol
