Description

[0001] Filter insert, jug insert and table water jug

[0002] The present invention relates to a filter insert for a table water jug, wherein the filter insert is designed for insertion into a jug container of the table water jug, wherein the filter insert comprises a housing with a housing opening and a housing cover for closing the housing opening in a filtering position and wherein the housing forms a housing receptacle for receiving a filter element.

[0003] Furthermore, the present invention relates to a jug insert for insertion into a jug container of a table water jug ​​in a defined manner, wherein the jug insert is designed to receive a filter insert in an insertion position in a defined manner.

[0004] Furthermore, the present invention relates to a table water jug ​​comprising a jug container with a jug container opening for filling with water and a spout for pouring out water, wherein the jug container is designed to receive a filter insert for filtering water received in the jug container.

[0005] Filter inserts, jug inserts, and table water jugs of the type described above are known in various designs. Such table water jugs are used in particular to treat tap water, for example, to filter and / or demineralize it.

[0006] To replace a used filter element, the filter insert must be opened. This typically involves moving the housing cover relative to the housing to release the housing receptacle, allowing access to the filter element contained within. Handling conventional filter inserts is often complicated. Therefore, intuitive operation for the user is particularly desirable.

[0007] US 2007 / 0151979 A1 discloses a water jug ​​and a lid therefor. WO 2022 / 152497 A1 relates to a filter device.

[0008] It is therefore an object of the present invention to improve a filter insert, a jug insert and a table water jug ​​of the type described above so that they are easier to handle.

[0009] This object is achieved according to the invention in a filter insert of the type described at the outset in that the filter insert comprises a housing cover guide device for guiding a movement of the housing cover relative to the housing when transferring the filter insert from an insertion position, in which the housing cover is completely separated from the housing, into the filter position.

[0010] Such a housing lid guide device makes it possible, in particular, to place the housing lid onto the housing in a defined manner and then to transfer it into the filter position. With a corresponding design of the housing lid guide device, it is then possible for a user to handle the filter insert by simply grasping the housing lid. In other words, the filter insert can be grasped by a user exclusively by the housing lid when, for example, it is inserted into the table water jug, in particular a jug insert thereof. This can in particular prevent the housing from becoming detached from the housing lid if a user grasps and handles the filter insert exclusively by the housing lid.

[0011] It is advantageous if the housing cover guide device comprises a slotted guide for guiding a movement of the housing cover relative to the housing along a guide track. Such a configuration makes it possible, in particular, to separate directions of movement from one another, for example, for a movement of the housing cover toward the housing for first engaging them with one another and then for moving the housing cover relative to the housing to transfer it into the filter position, in which the housing cover can optionally be locked to the housing or is locked. This prevents, in particular, unintentional detachment of the housing cover from the housing if the filter insert is handled by a user exclusively by the housing cover.

[0012] It is advantageous if the guideway is straight or curved. In particular, it can be L-shaped or U-shaped. L-shaped or U-shaped guideways enable separation of movement in different directions, as described above. This allows for safe handling of the filter insert on the housing cover, as explained.

[0013] For reliable guidance of the housing cover on the housing, it is advantageous if the slotted guide comprises at least two, in particular four, guide grooves and if the guide grooves define the guide path.

[0014] The slotted guide preferably comprises at least two, in particular four, guide members that interact with and engage in the guide grooves. Thus, the slotted guide can serve both to guide a relative movement of the housing cover and the housing and to connect or couple them to one another in a defined manner.

[0015] In order to prevent the housing cover from becoming accidentally detached from the housing, it is advantageous if each guide link is locked into the associated guide track in the filter position.

[0016] Locking or latching the housing cover to the housing in the filter position can be achieved particularly easily if a locking recess is formed on each guide track, into which the associated guide member engages or snaps when the filter position is reached. Such a locking or snapping action provides the user with haptic feedback that the housing cover has reached the desired filter position.

[0017] It is advantageous if each guide member is arranged on a spring element that deforms from a basic position toward the housing receptacle upon insertion into the guide track and springs back to its basic position when locked into the locking recess in the direction away from the housing receptacle. Such a design of the filter insert enables, in particular, a simple locking of the housing cover with the housing in the filter position.

[0018] In order to avoid the formation of undesirable projections on the housing, which could in particular damage a filter insert when it is inserted into the housing receptacle, it is advantageous if the at least two guide members are arranged or formed on the housing cover.

[0019] Advantageously, the filter insert comprises a housing cover locking device for locking the housing cover to the housing in the filtering position. This ensures, in particular, that the housing cover cannot be removed from the housing without overcoming the housing cover locking device.

[0020] The filter insert can be designed particularly simply and compactly if the housing cover locking device comprises the at least two guide members and the locking recesses on the at least two guide points. In other words, the at least two guide members and the locking recesses associated with them form housing cover locking device elements that interact, particularly in the filter position, namely, they engage in a force-locking and / or positive-locking manner.

[0021] It is advantageous if at least one water inlet is formed on the housing cover, and at least one water outlet is formed on the housing. This allows water to flow through the housing cover into the housing receptacle and out of the housing through the at least one water outlet. Thus, water can be filtered and / or demineralized as it flows through the filter insert by means of a filter element accommodated in the housing receptacle.

[0022] In particular, to prevent the filter element or parts thereof from escaping from the housing, it is advantageous if at least one water outlet is sealed by a mesh filter. If the filter element comprises filter particles, such as beads, contained in a bag-like container, this can prevent such beads from escaping from the housing through the water outlet in the event of damage to the container.

[0023] The housing can be designed in a simple manner if at least one water outlet is circular.

[0024] Furthermore, it is advantageous if the housing tapers from a housing top, which encompasses the housing opening, to a housing bottom, which encompasses the at least one water outlet. Such a design makes it possible, in particular, to insert the filter insert into a correspondingly tapered jug insert of a tabletop water jug. In particular, this allows for a simple, form-fitting reception of the filter insert in the jug container or in the jug insert of the tabletop water jug.

[0025] To simplify the insertion of a filter element into the housing receptacle, it is advantageous if the housing cover is designed to be completely detachable from the housing. It can then be completely removed to load the housing with the filter element.

[0026] According to a further preferred embodiment, the housing opening can be delimited by a housing opening edge, and a circumferential edge flange extends from the housing opening edge away from the housing opening. Such a configuration can be used, in particular, to place the housing cover in a defined manner on the housing for closing the same. The circumferential edge flange can thus, in particular, limit movement of the housing cover toward the housing.

[0027] Furthermore, it may be advantageous if the housing opening edge comprises two rectilinear housing opening edge sections that run parallel to each other, and if the rectilinear housing opening edge sections run parallel to a preferred housing axis. The rectilinear housing opening edge sections can, in particular, guide a movement of the housing cover relative to the housing, supporting the guide link. They can, in particular, form part of the housing cover guide device to guide the housing cover into the filter position for a final movement relative to the housing.

[0028] Furthermore, it can be advantageous if the housing opening edge comprises two convexly curved housing opening edge sections pointing away from the housing opening, and if the curved housing opening edge sections connect the two rectilinear housing opening edge sections. This allows an overall elongated, oval housing opening edge to be formed. In particular, the shape of the curved housing opening edge sections can be adapted to an inner contour of a jug insert in order to seal the filter insert relative to the jug insert. This can ensure, for example, that unfiltered water poured into the jug insert must flow through the filter insert to exit the jug insert.

[0029] It is advantageous if the slotted guide is designed such that the housing cover touches the housing when the at least two guide members and the at least two guide grooves come into contact in the region of one of the two curved housing opening edge sections, and touches the other of the two curved housing opening edge sections in the filter position. Such a design makes it possible, in particular, for a user to immediately recognize whether the housing cover on the housing is already in the filter position or not. This can be indicated to the user in particular by a marking being applied in the region of one of the housing opening edge sections, which marking is only visible when the housing cover and the housing are in the filter position, in particular when they are locked in this position.

[0030] It is advantageous if, in the filter position, an edge contact surface of the housing opening edge is at least partially visible in the region of one of the two curved edge sections of the housing opening edge, which contact surface contacts the housing cover when the at least two guide elements and the at least two guide grooves come into contact. As already explained, this allows a user to be immediately informed that the filter insert is in the filter position, meaning that the housing cover is positioned relative to the housing in such a way that it is secured to the housing in a defined manner.

[0031] It is advantageous to have a directional arrow on the visible area of ​​the edge support surface in the filter position. This arrow indicates the direction of movement of the housing cover relative to the housing for transferring the filter insert from the filter position to the insertion position. This allows the user to immediately see in which direction the housing cover must be moved to remove it from the housing.

[0032] According to a further preferred embodiment, it can be provided that the housing opening edge comprises a can insert contact edge extending away from the housing receptacle and transversely to the edge support surface, which, in an insertion position in which the filter insert is inserted flat into the can insert, rests flat against a circumferential can insert wall tapering from a can container opening in the direction of a container base of the can container. This configuration makes it possible, in particular, to seal the filter insert relative to the can insert using the filter insert, in particular the can insert contact edge. In particular, it can be prevented that water filled into the can insert can flow past the filter insert. Rather, it can be achieved that water filled into the can insert must necessarily flow through the filter insert in order to get out of the can insert.

[0033] Preferably, the can insert contact edge is inclined at an angle relative to a can insert's longitudinal axis. This configuration can, in particular, create a type of conical sealing surface, both on the filter insert and on the can insert. This allows for a reliable seal between the filter insert and the can insert in the inserted position.

[0034] The angle of inclination is advantageously in a range of approximately 3° to approximately 12°. This can prevent self-locking when the filter insert and the jug insert are engaged, particularly with the appropriate choice of materials.

[0035] Advantageously, the housing opening edge has an edge contact surface facing away from the underside of the housing. This allows, in particular, the housing cover to be brought into contact with the housing in a defined manner.

[0036] In order to be able to specify a defined positioning of the housing cover on the housing, it is advantageous if the housing cover rests on the edge support surface in the filter position.

[0037] It is advantageous if the housing cover comprises an outer, circumferential cover rim, and if the cover rim comprises a cover edge surface that rests on the edge support surface in the filter position. This design makes it possible, in particular, to seal the housing cover against the housing in the area of ​​the circumferential cover rim by means of the adjacent edge support and cover edge surfaces.

[0038] Preferably, the guide rail is designed such that when the housing cover moves relative to the housing, the edge support surface and the cover edge surface remain parallel to each other. This makes it easy to prevent, in particular, the housing cover from tilting relative to the housing.

[0039] It is advantageous if the housing opening defines a preferred housing axis and if the housing cover resting on the edge support surface can be moved parallel or substantially parallel to the preferred housing axis. This allows, in particular, a simple and user-recognizable displacement movement to be specified for moving the housing cover relative to the housing into the filter position.

[0040] A parallel movement of the housing cover and the housing to the edge support surface can be achieved in a simple manner by the guideway comprising a guideway section that runs parallel to the edge support surface.

[0041] It is advantageous if the at least two guide grooves are formed, starting from the edge support surface, in a wall surface of the housing facing the housing receptacle. In particular, the at least two guide grooves can form recesses in the edge support surface. Such a configuration makes it particularly easy to engage the housing cover and the housing. For example, the guide members can be placed on the edge support surface and the housing cover can be moved relative to the housing until the guide members engage in the guide grooves. It is then possible to guide a movement of the housing cover relative to the housing by means of the guide grooves of the slotted guide. According to a further preferred embodiment, it can be provided that at least one support web for the filter element is formed on a housing underside, protruding in the direction of the housing receptacle.Such a design makes it possible, in particular, to position the filter element slightly away from the water outlet. This simplifies and improves the flow through the filter insert.

[0042] Advantageously, the at least one support web extends transversely, particularly perpendicularly, to the preferred axis of the housing. This allows the support webs to be kept as short as possible. Furthermore, they can support a filter element particularly reliably and stably.

[0043] To facilitate handling of the filter insert, it is advantageous for the operator if the housing cover has at least one recessed grip pointing away from the housing mount. This can be used, for example, to grasp or manipulate the housing cover, for example, by moving it relative to the housing.

[0044] Advantageously, the at least one water outlet is located in the area of ​​the at least one recessed grip. This ensures, in particular, that water can flow reliably through the filter insert and prevents unwanted standing water from forming, where movement through the filter insert is no longer possible.

[0045] The housing preferably has a housing base and a housing foot protruding from the base. Such a housing base can serve the purpose in particular of setting down the filter insert in the desired manner. It can also have a centering function, for example to center the filter insert in a jug insert. For this purpose, a corresponding recess or opening can be provided on the jug insert, for example, into which the housing base can engage when the filter insert is inserted into the jug insert as intended. It is advantageous if at least one water outlet is formed on the housing base. If the housing base forms the lowest point of the filter insert, water can reliably escape from the filter insert.

[0046] In order to keep a filter element spaced from the housing base, it is advantageous if at least one support web is formed on the housing base.

[0047] According to a further preferred embodiment, the filter insert can comprise a filter element with a flexible, fluid-permeable filter bag, and a filter material can be accommodated in the filter bag. The filter material can, in particular, be granular or spherical, so that it is securely held in the filter bag and cannot escape from it in an undesired manner. The filter material can, in particular, be designed to filter out suspended matter and / or to demineralize water, for example, to descale.

[0048] For ease of manufacture and handling, it is advantageous if the housing cover defines a preferred housing axis and is designed symmetrically with respect to two mutually perpendicular mirror planes and if one of the two mirror planes contains the preferred housing axis.

[0049] Furthermore, it is advantageous for the manufacture and handling of the filter insert if the housing is designed to be mirror-symmetrical with respect to a mirror plane containing the preferred axis of the housing. In particular, it can only be designed to be mirror-symmetrical with respect to this one mirror plane. This ensures, in particular, that there is only one way to couple the housing cover to the housing.

[0050] The object posed at the outset is further achieved according to the invention in a jug insert of the type described at the outset in that the filter insert is designed in the form of one of the advantageous embodiments of filter inserts described above. Developing a jug insert of the type described at the outset in this way then has, in particular, the advantages described above in connection with preferred embodiments of filter inserts. Such a jug insert can, in particular, divide a jug container into two regions, namely a region enclosed by the jug insert and a region between the jug insert and the jug container.In particular, unfiltered or untreated water can be poured into the jug insert and filtered or treated by the filter insert inserted in the jug insert. It can then flow from the jug insert through the filter insert into the area of ​​the jug container, which is bordered on one side by the jug container and on the other by the jug insert. This area then contains filtered or treated water, for example, demineralized water.

[0051] Advantageously, the jug insert has a jug insert base with a jug insert base opening. This makes it possible, in particular, to position the filter insert so that water can only exit through the jug insert base opening after it has previously flowed through the filter insert. This allows untreated water to be collected in the jug insert and then, after filtering or demineralization, flow through the jug insert base opening into the area of ​​the jug container where treated water is collected.

[0052] To create the slimmest possible jug container, it is best to have an elongated oval opening at the bottom of the jug insert. This makes it possible to open almost the entire jug insert base, achieving a high filtration rate.

[0053] It is advantageous if at least one guide rib is formed on an inner wall surface of the jug insert, extending from the jug insert base, to center the filter insert when inserted into the jug insert. This prevents the filter insert from becoming jammed in the jug insert or from assuming an undefined position. In particular, this ensures that the water outlet provided on the filter insert is positioned in a defined manner in the area of ​​the jug insert base opening. This ensures, in particular, the reliable function of the table water jug.

[0054] Advantageously, several guide ribs are provided that rest flat against the outside of the housing when the filter insert is inserted into the jug insert. In other words, the filter insert can be supported by the guide ribs. At the same time, the guide ribs position it in the desired position within the jug insert.

[0055] Preferably, the at least one guide rib has a sliding surface that interacts with the housing. Such a sliding surface facilitates, in particular, the insertion of the filter insert into the jug insert. The sliding surface can be shaped such that it can guide the movement of the filter insert along a desired path when inserted into the jug insert.

[0056] For this purpose, it is particularly advantageous if the sliding surface is partially straight and partially convexly curved toward the housing receptacle. This design makes it possible, especially when multiple guide ribs are provided, to center the filter insert, initially inserted unguided into the jug insert, using curved sections of the sliding surface and then bring it into its final insertion position.

[0057] Furthermore, it is advantageous if the housing base of the filter insert is immersed in the jug insert base opening when the filter insert is accommodated in the jug insert. In particular, if the at least one water outlet encompassed by the filter insert is arranged or formed on the housing base, a virtually unhindered flow of the water to be treated through the filter insert, starting from the jug insert, through the jug insert base opening into the jug container, can be achieved. The object stated at the outset is further achieved according to the invention in a table water jug ​​of the type described at the outset in that it comprises a filter insert which is designed in the form of one of the advantageous embodiments of filter inserts described above.

[0058] A table water jug ​​designed in this way has in particular the advantages already described above in connection with preferred embodiments of filter inserts.

[0059] Furthermore, it is advantageous if the jug container comprises a jug insert for holding unfiltered water, and if the jug insert is accommodated in a jug insert position within the jug container to separate container areas for untreated and treated water. As already explained, the jug insert can be filled with untreated water. If the filter insert is accommodated in the jug insert and positioned so that water can only flow out of the jug insert after flowing through the filter insert through the opening in the base of the jug insert, untreated and treated water can be separated from each other in a defined and hygienic manner.

[0060] Preferably, the jug insert is designed in the form of one of the preferred embodiments of jug inserts described above. The table water jug ​​then also has the advantages already described above in connection with preferred embodiments of jug inserts.

[0061] Furthermore, it is advantageous if the table water jug ​​comprises a container lid for closing the jug container opening in a closed position. This can in particular prevent dirt from penetrating the table water jug. It is advantageous if the container lid is designed in the form of a lid device, if the lid device comprises a lid with a filling opening, in particular for filling the jug container with the lid device in place, and a filling opening lid for closing the filling opening in a closed position, and if the filling opening lid can be moved from the closed position into a filling position, in which it at least partially exposes the filling opening, and vice versa. Such a configuration makes it possible, in particular, to fill the table water jug ​​with untreated water without having to remove the container lid.To do this, the filling opening cover only needs to be moved from the closed position to the filling position to release the filling opening.

[0062] For a simple connection of the lid device to the jug container or jug ​​insert, it is advantageous if the table water jug ​​includes a lid coupling device for force-fitting and / or positive coupling of the lid device to the jug container or jug ​​insert in the closed position. It is particularly conceivable to couple the lid device to the jug container on the one hand or the jug insert on the other hand in the closed position.

[0063] The table water jug ​​is easy to handle if the lid coupling device is designed in the form of a first locking or snap-on connection device. The container lid can thus be easily snapped or snapped onto the jug container or jug ​​insert by a user.

[0064] The lid device preferably comprises a lid holding device without undercuts for holding the filling opening lid on the lid in a holding position by purely force-fitting means. A lid device designed in this way makes it possible, in particular, to easily lift the filling opening lid from the lid. Undercuts do not need to be disengaged in this design. Furthermore, it is advantageous if the filling opening lid is designed to be movable from the holding position into a separation position, in which the filling opening lid is removed and separated from the lid. In this way, the lid and the filling opening lid can be easily separated from one another, for example, for cleaning.

[0065] For ease of use, the water jug's filling opening lid is designed to slide smoothly on the lid when moving from the closed position to the filling position and vice versa. The user then only needs to apply a slight actuating force to move the filling opening lid from the closed position to the filling position and vice versa.

[0066] Furthermore, it may be advantageous if the lid device comprises a locking mechanism for locking the filling opening lid in at least one locking position. Such a configuration has the particular advantage that the filling opening lid can then be locked in a defined position on the lid. For example, this can be the closed position, the filling position, or any other position. This can ensure, for example, that the filling opening cannot be accidentally closed by the filling opening lid when filling the table water jug ​​with water.

[0067] Preferably, the at least one locking position defines the closed position and / or the filling position. In this way, the filling opening cover can be secured to the cover, particularly in the closed position and / or the filling position. Moving it out of the locking position then requires additional force.

[0068] The lid device can be formed in a simple manner if the locking device comprises cooperating first and second locking elements which are arranged or formed on the one hand on the lid and on the other hand on the filling opening lid, and if the cooperating first and second locking elements are in force-locking and / or positive-locking engagement in the at least one locking position.

[0069] A contactless locking mechanism can be achieved, in particular, by the first and second locking elements, which interact in at least one locking position, engaging through magnetic interaction. The locking elements are thus held in the locking position by a magnetic force. For example, the locking elements can comprise two magnets or be formed by magnets that are aligned in the locking position such that the south pole of one magnet and the north pole of the other magnet are directly opposite each other and thus attract each other.

[0070] Furthermore, it may be advantageous if the lid holding device comprises a magnetic holding device for magnetically holding the filling opening lid on the lid in the holding position by means of magnetic force. In particular, this can be achieved exclusively by means of magnetic force. Such a design makes it possible, in particular, to completely dispense with undercuts for coupling the filling opening lid to the lid. The filling opening lid can then be removed from the lid simply by a user overcoming the magnetic attraction force and lifting the filling opening lid off the lid.

[0071] The magnetic holding device preferably comprises at least two cooperating holding elements, which are arranged or formed on the one hand on the filling opening cover and on the other hand on the cover. They can attract each other, in particular through acting magnetic forces, and thus hold the filling opening cover to the cover. Conveniently, at least one of the at least two cooperating holding elements is magnetic. For example, it can be designed in the form of a magnet. Such a holding element can cooperate, in particular, with another magnet or with a magnetizable holding element to hold the filling opening cover in the holding position on the cover.

[0072] The table water jug ​​can be designed in a simple and compact manner if at least one magnetic holding element is arranged or formed on the filling opening lid.

[0073] According to a further preferred embodiment, the container lid can be provided to close the jug insert in the closed position. Such a configuration allows, in particular, the option of leaving the jug container partially open. In particular, the spout can remain free.

[0074] Preferably, the container lid releases the spout when closed. This allows treated water to be drawn from the tabletop water jug ​​by pouring it out of the spout, even when the container lid is covering the jug insert.

[0075] Conveniently, the tabletop water jug ​​is designed as a tabletop water filter jug ​​for filtering water. As already described, untreated water can be poured into the jug insert. With appropriate positioning, it can then flow through the filter insert to reach a collection area in the jug container, from which it can then be removed or poured out through the spout.

[0076] Preferably, the jug insert borders on the spout in the jug insert position and exposes the latter. This enables easy handling of the table water jug, in particular the removal of treated water from the same, specifically by simply pouring it out of the spout. According to a further preferred embodiment, it can be provided that the jug container comprises an insert coupling device for the force-fitting and / or form-fitting coupling of the jug container and the jug insert in the jug insert position. This configuration makes it possible, in particular, to position the jug insert in a defined manner in the jug container. Furthermore, it can be prevented, in particular, that the jug insert can move in an undesired manner in the jug container, for example when filling with water or when pouring water from the table water jug.

[0077] The table water jug ​​can be designed in a particularly simple manner if the insert coupling device is designed in the form of a second locking or snap-in connection device.

[0078] Furthermore, it is advantageous if the insert coupling device comprises cooperating first and second insert coupling elements, which are arranged or formed on the one hand on the jug container and on the other hand on the jug insert, and if the first and second insert coupling elements engage in a force-locking and / or positive-locking manner in the jug insert position. Such an insert coupling device enables, in particular, easy handling by a user. Furthermore, the table water jug ​​can be manufactured in this way in a simple manner.

[0079] Preferably, the first and second insert coupling elements are designed as second locking or snap-on connection elements. These can engage in a force-locking and / or positive-locking manner, particularly in the can insertion position.

[0080] Furthermore, it can be advantageous if the jug insert can be removed from the jug container when closed. This makes it possible, in particular, to leave the container lid on the jug insert while still removing the jug insert from the jug container. In other words, the container lid does not have to be removed from the tabletop water jug ​​to remove the jug insert.

[0113] Figure 33: a view similar to Figure 32, with the water jug ​​in the closed position; and

[0114] Figure 34: a sectional view along line 34-34 in Figure 32. Figures 1 to 27 schematically show an embodiment of a table water jug, designated overall by the reference numeral 10.

[0115] The table water jug ​​10 is designed as a table water filter jug ​​12 for treating, in particular for filtering, water.

[0116] The table water jug ​​10 comprises a jug container 14, a jug insert 16, a lid device 18 and a filter insert 20. The above-mentioned components are described in detail below, in particular their interaction.

[0117] The jug container 14 has an elongated oval shape, as clearly visible in the top view in Figures 7 and 8. A circumferential edge protrudes from a bottom 22, forming a base. A circumferential wall 28 protrudes from the bottom 22, which, when the table water jug ​​is used as intended, extends against the direction of gravity, symbolized by arrow 26 in Figure 2. The wall 28 extends to an upper edge 30 of the jug container 14.

[0118] A spout 32 is formed on the jug container 14, specifically by a lateral bulge 34 of the wall 28 on a semi-hollow-cylindrical wall section 36. The wall section 36 connects two parallel, flat wall sections 38 and 40. Opposite the wall section 36, along a center line 42 extending between the wall sections 36 and 38, which moreover runs in a plane of symmetry of the table water jug ​​10, another semi-hollow-cylindrical wall section 44 is formed, which also connects the wall sections 38 and 40.

[0119] The table water jug ​​10 comprises a jug handle 46, which is arranged on the wall section 44. It comprises two curved sections that are integrally formed on the wall section 44 and connected to one another via a handle section 48 running parallel to the wall section 28. Overall, a substantially U-shaped jug handle 46 is thus formed. The jug handle 46 serves to hold the table water jug ​​10 with one hand. As described, it is arranged or formed laterally on the jug container 14. The spout 32 and jug handle 46 elements, formed on the one hand on the wall section 36 and on the other hand on the wall section 44, point in opposite directions and each away from the jug container 14.

[0120] The spout 32 formed on the side of the jug container 14 extends to the upper edge 30. In Figure 3 it can be clearly seen that the spout 32 forms a bulge 34 on the edge 30.

[0121] The can container 14 defines a can container opening 50 in the region of the upper edge 30. The lid device 18 forming a container lid 52 serves to close the opening. In this exemplary embodiment, the container lid 42 is not coupled directly to the can container 14, but indirectly via the can insert 16. A lid coupling device 54 serves to couple the container lid 52 to the can container 14. It is designed for the force-fitting and / or form-fitting coupling of the lid device 18 to the can container 14, specifically indirectly via the can insert 16.

[0122] The lid coupling device 54 is designed in the form of a first locking or snap-in connection device 56. The lid coupling device 54 comprises cooperating first and second lid coupling elements 58 and 60, which are arranged or formed on the one hand on the can insert 16 and thus indirectly on the can container 14, and on the other hand on the container lid 52.

[0123] In a closed position, in which the container lid 52 closes the can container opening 50, the first and second lid coupling elements 58, 60 are engaged in a force-locking and / or positive-locking manner, as can be clearly seen in Figure 12. Figure 1 also shows the closed position. The first and second lid coupling elements 58 and 60 are designed in the form of a lid coupling element projection 62 on the container lid 52 and a lid coupling element recess 64 corresponding thereto.

[0124] The first and second lid coupling elements 58 and 60 are designed as first and second locking or snap-in connection elements. The first lid coupling element forms a first locking element 66 in the form of a locking recess, and the second lid coupling element 60 forms a first locking or snap-in connection element in the form of a locking lug that engages the locking recess in the closed position. This can be clearly seen in Figure 12.

[0125] The first lid coupling elements 58 are formed on the jug insert 16 in the form of recesses that open toward one another. They are formed adjacent to the spout 32 on the one hand and adjacent to the jug handle 46 on the other. Thus, two first lid coupling elements 58 are formed on the jug insert 16, and two second lid coupling elements 60 are formed on the container lid 52.

[0126] As shown in Figure 4, the can insert 16 is received in the can container 14 in an inserted position. In the closed position, the container lid 52 closes the can insert 16, as can be clearly seen in Figure 2. In the closed position, the container lid 52 exposes the spout 32. As can be clearly seen in Figure 4, the can insert 16 also exposes the spout 32 in the inserted position. However, it borders on the spout, which is also clearly visible in the sectional view of Figure 2.

[0127] The table water jug ​​10 further comprises an insert coupling device 70 for force-fitting and / or positive-locking coupling of the jug container 14 and the jug insert 16 in the insert position. The insert coupling device 70 is designed in the form of a second locking or snap-in connection device 72.

[0128] The insert coupling device 70 comprises first insert coupling elements 74 and second insert coupling elements 76, which are arranged or formed on the one hand on the can container 14 and on the other hand on the can insert 16. In the inserted position, the first and second insert coupling elements 74 and 76 are engaged in a force-fitting and / or positive-locking manner. The first and second insert coupling elements 74 and 76 are designed as second locking or snap-in connection elements 78 and 80, respectively. They are engaged in the inserted position, as can be clearly seen in Figures 5 and 6.

[0129] The insert coupling device 70 comprises a total of four first insert coupling elements 74 and four corresponding second insert coupling elements 76. The four first insert coupling elements 74 are arranged or formed in the transition region between the wall sections 36 and 38 or 40 and 44, respectively, in the form of depressions which are formed slightly below the edge 30 in an inner wall surface 82 of the wall 28.

[0130] The second insert coupling elements 76 are designed as short ribs 84 that extend parallel to an upper edge 86 of the jug insert 16. The edge 86 is circumferential and, viewed from above, has an elongated oval shape. It fits snugly against the wall 28 in the region of the edge 30, but does not follow the bulge 34. Thus, the spout 32 remains free.

[0131] As clearly shown in Figure 3, the can insert 16 can be removed from the can container 14 in the closed position, i.e., with the container lid 52 coupled to the can insert 16. Therefore, the container lid 52 does not need to be removed from the can insert 16. Conversely, the can insert 16 can also be inserted into the can container 14 with the container lid 52 in place.

[0132] Slightly set back from the edge 86, the can insert 16 tapers towards the underside 22, as can be clearly seen in Figure 2, when the can insert 16 is accommodated in the can container 14 as intended.

[0133] The further design of the jug insert 16 will be explained in more detail later in connection with the description of the filter insert 20.

[0134] The design of the cover device 18 will now be explained in more detail.

[0135] The lid device 18 comprises a lid 88 with a filling opening 90. It serves, in particular, the purpose of filling the can container 14 with the lid device 18 in place. To close the filling opening, the lid device 18 comprises a filling opening cover 92. The filling opening cover 92 can be moved from a closed position, in which it closes the filling opening 90, for example, as shown in Figure 8, into a filling position, in which it at least partially exposes the filling opening 90. The filling position is shown schematically in Figure 7.

[0136] The lid device 18 further comprises a lid holding device 94. It is free of undercuts and designed to hold the filling opening cover 92 on the cover 88 purely by force. This design makes it possible to move the filling opening cover 92 from a holding position, in which the filling opening cover 92 is held on the cover 88, as shown schematically in Figure 10, for example, into a separating position, in which the filling opening cover 92 is removed and separated from the cover 88. Figure 9 shows such a situation. The exploded view in Figure 9, particularly in the area of ​​the filling opening cover 92, shows the coupling to the cover 88 without an undercut. The filling opening cover 92 is designed to slide on the cover 88 when transferred from the closed position to the filling position and vice versa. For this purpose, the lid device 18 comprises a plurality of sliding elements 96. They are designed in the form of sliding projections 98.In the embodiment of Figures 1 to 27, the sliding elements 96 are arranged or formed on the filling opening cover 92.

[0137] The sliding projections 98 are knob-like and protrude from an underside 100 of the filling opening cover. A total of four sliding elements 96 are formed on the filling opening cover 92 and are positioned near a circumferential edge 102. A sliding surface 104, which is arranged or formed on the cover 88, interacts with the sliding elements 96. The sliding surface 104 is flat and laterally delimits the filling opening 90 in sections. The sliding elements 96 rest against the sliding surface 104 when the filling opening cover 92 is moved from the closed position to the filling position and vice versa. This can be seen particularly clearly in Figures 13 and 14. Figure 13 shows the filling position, Figure 14 the closed position.

[0138] The lid device 18 comprises a locking device 106 for locking the filling opening lid 92 in at least one locking position. In the exemplary embodiment illustrated in Figures 1 to 27, the filling opening lid 92 is locked in both the closed position and the filling position, as will be explained in more detail below. Thus, both the closed position and the filling position each define a locking position. In alternative exemplary embodiments, it is also conceivable to lock either only the closed position or only the filling position.

[0139] The locking device 106 comprises cooperating first and second locking elements 108 and 110, which are arranged or formed on the one hand on the cover 88 and on the other hand on the filling opening cover 92. The cooperating first and second locking elements 108 and 110 are engaged in a force-locking and / or positive-locking manner in at least one locking position.

[0140] In Figures 7 and 8, it can be clearly seen that the first and second locking elements 108 and 110 form cooperating locking projections 112 and locking receptacles 114. Two locking elements 108 are arranged in pairs opposite one another on an elongated guide receptacle, specifically on a circumferential guide receptacle edge 118 that delimits the guide receptacle.

[0141] The guide receptacle 116 is groove-shaped on the lid 88 and, relative to the sliding surface 104, is set back toward an interior space 120 of the can container 14. The first locking elements 108 are in the form of locking knobs 122. They are arranged adjacent to a free end 124 of the guide receptacle 116 in such a way that the second locking element 110, which is in the form of a locking projection 112 projecting from the filling opening lid 92 beyond the underside 100, can engage.

[0142] The free end 124 is formed adjacent to the filling opening 90; opposite it, another free end 126 of the guide receptacle 116 is delimited by the guide receptacle edge 118. Two locking studs 122 are also positioned adjacent here. The locking studs 122, each of which interacts with one of the two ends 124 and 126, are positioned such that the locking projection 112 can engage or snap into the locking receptacles 114 delimited by the locking studs 122 and the ends 124 and 126, respectively.

[0143] Figure 7 shows the locking projection 112 in cooperation with the

[0144] End 126. The locked locking projection 112 thus defines the filling position of the lid device 18. The locking projection 112 locked between the two locking knobs 122 and the end 124 defines the closed position of the lid device 18.

[0145] A circumferential inner edge surface 128 is formed on the cover 88. The edge surface 128 defines stops 130 and 132 acting in opposite directions for the filling opening cover 92. In the closed position, the filling opening cover 92 rests against the stop 130 adjacent to the filling opening 90. In the filling position, the edge 102 of the filling opening cover 92 rests against the stop 132.

[0146] The edge surface 128 extends transversely, in the embodiment shown in the figures vertically, away from the sliding surface 104.

[0147] A contour of the edge surface 128 corresponds to an outer contour, thus the edge 102, of the filling opening cover 92 such that the filling opening cover 92 and the edge surface 128 lie flat against each other, or essentially flat, both in the filling position and in the closed position. This is particularly clearly visible in Figures 7 and 8, as well as 13 and 14.

[0148] In the embodiment illustrated in the figures, the lid holding device 94 comprises a magnetic holding device 134 for magnetically holding the filling opening lid 92 on the lid 88 in the holding position by means of magnetic force. In the present embodiment, the filling opening lid 92 is held on the lid 88 exclusively by means of magnetic force.

[0149] The magnetic holding device 134 comprises two cooperating holding elements 136 and 138. The holding element 136 is arranged or formed on the filling opening cover 92, and the holding element 138 is arranged or formed on the cover 88. The holding element 136 is magnetic. It is designed in the form of a magnet 140. The magnetic holding element 136 is rotationally symmetrical with respect to a holding element longitudinal axis 142. It comprises a holding flange 144 projecting radially relative to the holding element longitudinal axis 142.

[0150] The holding element 136 is held in a holding element receptacle 146. The holding element receptacle 146 is formed in the form of a recess on the locking projection 112. The holding element receptacle 146 is rotationally symmetrical with respect to the holding element longitudinal axis 142. It comprises an annular surface 148 facing away from the underside 100, against which the holding flange 144 rests. In order to hold the holding element 136 in the holding element receptacle 146, the holding device 134 comprises a holding member 150. It is sleeve-shaped and has a retaining flange 152 projecting in the radial direction relative to the holding element longitudinal axis 142. Detent lugs 154 protrude from a sleeve-shaped outer side and engage in detent recesses 156 on the holding element receptacle 146. An end face 158 at the end of the holding member 150 facing away from the retaining flange 152 bears against the holding flange 144.

[0151] To mount the magnet 140 on the filling opening cover 92, proceed as schematically shown in Figures 16 and 17. The magnet 140 is inserted with the retaining flange 144 first into the retaining element receptacle 146 parallel to the retaining element longitudinal axis 142. To fix the magnet 140, in the next step, the retaining member 150 is inserted into the retaining element receptacle 146 with the end face first, which is interrupted in the circumferential direction relative to the retaining element longitudinal axis 142 and is therefore only formed at individual spring tabs 160, surrounding the magnet 140, until the end face 158 abuts the retaining flange 144. The locking lugs 154 slide into the locking recesses 156 and thus establish a locking connection between the retaining member 150 and the retaining element receptacle 146. The holding member 150 serves to hold the holding element 136 in the holding element receptacle 146 in a force-fitting and / or form-fitting manner.As described, the holding member 150 and the holding element receptacle 146 are latchingly connected to one another when they hold the holding element 136 in the holding element receptacle 146.

[0152] The filling opening cover 92 is designed to be mirror-symmetrical with respect to a mirror plane 162 containing the holding element longitudinal axis.

[0153] For handling the filling opening cover 92, a rib 164 extending in the mirror plane 162 is formed on an upper side of the filling opening cover 92.

[0154] In the embodiment illustrated in the figures, the second holding element 138 is designed to be magnetizable. It is formed at least partially from a magnetizable material. This is a metallic material containing iron, cobalt, and / or nickel.

[0155] The magnetizable holding element 138 is designed in the form of a holding strip 166. A holder 168 for the holding strip 166 is formed on an underside of the cover 88. It comprises two laterally open grooves 170 facing one another, into which the holding strip 166 can be inserted parallel to the groove-shaped guide receptacle 116.

[0156] A cover 172, which forms a retaining element receptacle 174, serves to protect the retaining strip 166, which is made of a non-corrosive material, from corrosion. Once the retaining strip 166 has been inserted into the holder 168, the cover 172 can be pushed over the holder 168 in a next assembly step. To support the retaining strip 166 along its extension, two guide webs 176, each with a recess 178, are arranged on an inner side of the cover 172, into which the retaining strip 166 engages when the cover 172 is placed on the holder 168. In this regard, particular reference is made to Figures 13, 14 and 19. The retaining strip 166 extends in a displacement direction 180. This is defined in particular by a longitudinal axis of the guide receptacle 116. The retaining strip 166 thus extends in the displacement direction 180 of the filling lid 92.

[0157] In the exemplary embodiment described in the figures, the retaining strip 166 has a length such that it interacts with the magnet 140 in any position of the filling opening cover 92 relative to the cover 88, i.e., both in the filling position and in the closed position, and in any other position between these two extreme positions. Thus, whenever the filling opening cover 92 is placed on the cover 88 as intended, the retaining element 136 magnetically interacts with the retaining strip 166. The retaining strip 166 is attracted by the magnet 140. Since the magnet 140 is held on the filling opening cover 92, the filling opening cover 92 is pulled against the cover 88.

[0158] The hood 142 is welded to the cover 88, ensuring that the retaining element receptacle 174 is sealed fluid-tight. The retaining strip 166 is thus protected against corrosion.

[0159] The lid device 18 further comprises a guide device 182 for guiding a movement of the filling opening lid 82 from the closed position to the filling position and vice versa. The guide device 182 comprises cooperating first and second guide elements 184 and 186. The first and second guide elements 184 and 186 are arranged or formed on the one hand on the filling opening lid 92 and on the other hand on the lid 88. In a guide position, they are engaged, in particular in a form-fitting manner. It is particularly noteworthy that the cooperating first and second guide elements 184 and 186 are engaged without undercuts. The first and second guide elements 184 and 186 are designed in the form of a guide projection 188 and the guide receptacle 116 corresponding to the guide projection.The guide projection 188, which thus also forms the locking projection 112, engages in the guide receptacle 116 in the guide position and guides a movement of the filling opening cover 92 from the closed position into the filling position and vice versa.

[0160] As already explained, the guide projection 188 protrudes from the underside 100 of the filling opening cover 92. In this embodiment, the guide projection 188 encompasses the holding element receptacle 146.

[0161] As explained, the holding element 136 in the form of the magnet 140 is arranged or formed on the guide projection 188. At least one locking element 108 cooperating with the guide projection 188 is arranged or formed on the guide receptacle 116 for locking the filling opening cover 92 to the cover 88 in the manner described in the closed position and in the filling position. The locking elements 108 are arranged or formed on the circumferential guide receptacle edge 118 delimiting the guide receptacle 116, specifically in the form of locking knobs 122.

[0162] The holding strip 166 extends parallel to the groove-shaped guide receptacle 116. Thus, in this embodiment, the first and second holding elements 136 and 138 are assigned to the first and second guide elements 184 and 186.

[0163] The first and second guide elements 184 and 186 are separated from each other in the guide position by a narrow air gap 190. The interacting guide elements 184 and 186 are virtually contact-free, thus enabling virtually frictionless guidance of the movement of the cover 88 and the filling opening cover relative to each other. As already explained, one of the two guide elements 184 and 186, namely the guide element 184, also forms the second locking element 110 of the locking device 106.

[0164] Adjacent to the hood 172, on the underside of the cover 88, is a change indicator 192. The change indicator 192 comprises a rotatable wheel 194, which is divided into twelve equal sectors labeled with numbers from 1 to 12. A marking 196 in the form of a short groove is formed on the hood 172, extending in the direction of the displacement direction 180. When the filter insert 20 is changed, the respective month can be set on the change indicator 192 by aligning the number corresponding to the month with the marking 196. This allows a user to immediately see when the filter insert 20 was last changed.

[0165] The can insert 16 and the filter insert 20 are described in more detail below. As already explained, the can insert 16 can be inserted into the can container 14 in a defined manner. Figure 2 schematically shows that the can insert 16 is designed to accommodate the filter insert 20 in the inserted position.

[0166] The can insert 16, coupled to the can container 14 by means of the insert coupling device 70, has a circumferential can insert wall 198 which extends in a funnel shape from the edge 86 to a can insert base 200. When the can insert 16 is received in the can container 14, the can insert base 100 is spaced from the underside 22 of the can container 10. A distance 202 of the can insert base 200 from the underside 22 amounts to approximately one-third of the total height of the can container 14, which is predetermined by a distance between the edges 24 and 30. The can insert 16 tapers geometrically similar to the shape of the edge 86, so that any section through the can insert 16 parallel to a plane defined by the edge 86 is each elongated oval-shaped.

[0167] A can insert base opening 204 is formed on the can insert base 200, which is also elongated oval-shaped.

[0168] On an inner wall surface 206 of the jug insert 16, several guide ribs 208 are arranged or formed, extending from the jug insert base 200. They serve, in particular, to center the filter insert 20 when inserting it into the jug insert 16.

[0169] In the exemplary embodiment of the can insert 16 illustrated in the figures, a total of six guide ribs 208 are provided. They each extend into a can insert space 210 defined by the can insert 16 and protrude transversely, in particular perpendicularly, from the inner wall surface 206. The guide ribs 208 are flat and have a sliding surface 212 extending into the can insert space 210. This sliding surface serves to guide the filter insert 20 into a filter insert position, as illustrated by way of example in Figures 2 and 25, when inserted into the can insert 16.

[0170] The sliding surface 212 is partially rectilinear and partially convexly curved toward the can insert space 210. Figure 25 shows a rectilinear section 214 and a curved section 216. The rectilinear section 214 extends from the can insert base 200 toward the edge 30. It then transitions into the convexly curved section 126, which points toward the can insert space 210 and ends at the inner wall surface 206.

[0171] The guide ribs 208 are designed such that, when the filter insert 20 is received in the jug insert 16, they rest flatly against the outside of the filter insert. The filter insert 20 comprises a trough-shaped housing 218 with a housing opening 220 and a housing cover 222 for closing the housing opening 220 in a filtering position. The housing 218 forms a housing receptacle 224 for receiving a filter element 226.

[0172] The filter element 226 comprises a flexible, fluid-permeable filter bag 228 in which a filter material 230 is accommodated. The filter material 230 can optionally be designed to filter out suspended matter and / or to demineralize, in particular to decalcify, water. For example, the filter material 230 can comprise a plurality of beads made of an ion-exchange material.

[0173] The housing 218 defines a housing top 232, on which the housing opening 220 is also formed, and a housing bottom 234. The housing 218 tapers from the housing top 232 to the housing bottom 234, similar to the can insert 16.

[0174] Two water outlets 236 are formed on the housing 218, specifically on the housing bottom 234. The two water outlets 236 are circular and each closed by a mesh filter 238. The mesh filter 238 is, of course, designed to be fluid-permeable.

[0175] A housing base 240 protrudes from the housing bottom 234. The water outlets 236 are formed on the housing base 240, as can be clearly seen in Figures 25 and 26, for example. Several support webs 242 for the filter element 226 are formed on the housing bottom 234. They protrude from the housing base 240 toward the housing receptacle 224. They serve the particular purpose of keeping the filter element 226 spaced apart from the water outlets 236 and the mesh filters 238.

[0176] In the exemplary embodiments illustrated in the figures, three support webs 242 are provided. They extend transversely, namely perpendicularly, to a preferred housing axis 244. This axis is defined in particular as parallel to two rectilinear and mutually parallel housing opening edge sections 246 of a housing opening edge 248 delimiting the housing opening 220.

[0177] When the filter insert 20 is received in the can insert 16, the housing base 240 of the filter insert 20 is inserted into the can insert base opening 204. This insertion is easily facilitated by the guide ribs 208 with their sliding surfaces, which interact with the housing 218 of the filter insert and force it into the can insert base opening. The guide ribs 208 then rest flatly against the outside of the housing 218, as can be clearly seen in Figures 2 and 25.

[0178] The filter insert 20 comprises a housing cover guide device 250 for the defined engagement and closure of the housing 218 with the housing cover 222. It serves to guide a movement of the housing cover 220 relative to the housing when transferring the filter insert 20 from an insertion position, in which the housing cover 222 is completely separated from the housing 218, into the filter position, in which the housing cover 222 closes the housing opening 220 of the housing 218. The insertion position is shown schematically in Figure 26.

[0179] The housing cover guide device 250 comprises a slotted guide 252 for guiding a movement of the housing cover 222 relative to the housing 218 along a guide track 254. In the embodiment illustrated in the figures, the guide track 254 is L-shaped. Thus, it is curved. Alternatively, the guide track 254 can also be linear or U-shaped.

[0180] The slotted guide 252 comprises at least two guide grooves 256, four in the embodiment shown in the figures. Two of the four guide grooves are identical in design. The guide grooves 256 define the guide track 254. The guide grooves 256 extend into a housing wall 258 of the housing 218 as recesses that are open toward the housing receptacle 224. They interrupt the housing opening edge 248 at an open end 260.

[0181] A circumferential edge flange 262 extends from the housing opening edge 248 away from the housing opening 220. This edge flange 262 is also interrupted by the open ends 260 of the guide grooves 256. The edge flange 262 defines an edge support surface 264. It extends outwardly from the housing opening edge 248.

[0182] A circumferential can insert support edge 266 extends from the edge support surface 264. It points away from the housing receptacle 224. In the inserted position, in which the filter insert 20 is inserted into the can insert 16, the can insert support edge 266 rests flat against the circumferential can insert wall 198, which tapers from the can container opening 50 toward a container bottom 268 of the can container 14. The can insert wall 198 defines the wall surface 206 delimiting the can insert space 210.

[0183] The can insert support edge 266 is inclined by an angle of inclination 274 relative to a can insert longitudinal axis 270. In the embodiment illustrated in the figures, the angle of inclination 274 is in a range from approximately 3° to approximately 12°.

[0184] The can insert contact edge 266 serves in particular to seal the filter insert 20 relative to the can insert 16. The can insert wall 198, like the can insert contact edge 266, is inclined by the angle of inclination 274 relative to the can insert longitudinal axis 272. In the filter insert position, as shown in Figure 2, the can insert contact edge 266 thus divides the can insert space 210 into a region above the can insert contact edge 266 and a region below the can insert contact edge 266. The guide ribs 208 are arranged or formed in the region below the can insert contact edge 266.

[0185] The housing opening edge 248 further has two convexly curved housing opening edge sections 276 and 278 pointing away from the housing opening 220, which connect the two rectilinear housing opening edge sections 246 to one another.

[0186] The can insert support edge 266 does not have a constant width across its circumference. It is formed with a constant width in the region of the rectilinear housing opening edge sections 246 and in the region of the curved housing opening edge section 276. This results in the edge support surface 264, which borders the housing opening edge section 276, widening starting from the area adjacent to the rectilinear housing opening edge sections 246. Opposite, however, the widening can insert support edge 266 in the region of the convexly curved housing opening edge section 278 results in the edge support surface 264 having a constant width, which corresponds to a width of the edge support surface 264 in the region of the rectilinear housing opening edge sections 246.

[0187] This configuration also has an effect on the configuration of the guide track 254. It comprises a first track section 280 extending transversely, almost vertically, from the edge support surface 264 in the region of the rectilinear housing opening edge sections 246 and an adjoining second track section 282 which runs substantially parallel to the edge support surface 264 and points in the direction of the housing opening edge section 278.

[0188] The design of the guide grooves 256 for forming the guide tracks 254, as well as the design of the can insert contact edge 266 and the adjacent edge support surface 264, results in a symmetry break in the filter insert 20. This means that the filter insert is only symmetrical to itself with respect to a single symmetry plane 284 containing the housing preferred axis 244. However, in a plane 286 perpendicular to this plane, the filter insert 20 as a whole is not mirror-symmetrical to itself.

[0189] Guide members 288 are arranged or formed on the housing cover 222, encompassed by the slotted guide 252, interacting with and engaging in the guide grooves 256. Each of the four guide members 288 is arranged on a spring element 290, which deforms slightly toward the housing receptacle 224 when the guide members 288, aligned in pairs facing away from each other, are inserted into the guide track 254 provided for them.

[0190] On each guide groove 256, a locking recess 292 is provided, which extends slightly into a housing wall 294. This enables each guide member 288 to lock with the associated guide track 254 in the filter position, in which the housing cover 222 closes the housing opening 220 in a defined manner. For this purpose, one of the locking recesses 292 is formed on each guide track 254 or guide groove 256, into which the associated guide member 288 locks or snaps upon reaching the filter position. This occurs because, upon locking with the locking recess 292, the spring element 290 springs back into the basic position in the direction away from the housing receptacle 224.

[0191] The filter insert 20 thus comprises a housing cover locking device 296 for locking the housing cover 222 to the housing 218 in the filtering position. The housing cover locking device 296 comprises the guide members 288 and the correspondingly formed locking recesses 292 on the guide grooves 256. Several slot-like water inlets 298 are formed on the housing cover 222, which is designed to be completely separable from the housing 218. They form openings in the housing cover 222. They allow water to flow from the jug insert space 210 above the filter insert 20 into the housing receptacle 224.

[0192] The housing cover 222 is designed in the form of a shallow trough and has a cover base 300 which is interrupted, thus forming an opening 302. A handle element 304 with a U-shaped cross section is formed offset from the cover base 300 in the region of the opening 302. Thus, on both sides of the handle element 304 on the housing cover 222, two recessed grips 306 are formed, opening away from the housing receptacle 224. A user can thus engage with their thumb and middle finger in one of the two recessed grips 306 and grasp the housing cover 222 by the handle element 304. The handle element 304 extends transversely to the housing's preferred axis 244.

[0193] The water inlets 298 are formed both in the area of ​​the two grip recesses 306 and on the handle element 304. Furthermore, the opening 302 also forms a water inlet 298.

[0194] The housing cover 222 comprises an outer circumferential cover edge 308, which defines a cover edge surface 310 pointing toward the housing receptacle 224. The circumferential cover edge 308 is connected to the two grip recesses 306 and the grip element 304 via an inclined circumferential annular wall 312. The housing cover 222 and the housing 218 are coordinated with one another such that the cover edge 308 rests on the edge support surface 264 with the cover edge surface 310 in the filter position. The link guide 252 is further configured such that when the housing cover 222 is moved relative to the housing 218, the edge support surface 264 and the cover edge surface 310 remain aligned parallel to one another. As described, the housing cover 222 rests on the edge support surface 264 in the filter position.The guide grooves 256 of the slotted guide 252 are further arranged and configured such that the housing cover 222 touches the housing 218 when the guide members 288 and the guide grooves 256 come into contact in the region of the curved housing opening edge section 276 and reaches up to the can insert contact edge 266 in this region. The housing cover 222 is initially moved toward the housing receptacle 224 by the predetermined first track section 280 until the cover edge surface 310 rests on the edge support surface 264. The guide members 288 are now located in the transition region between the first and second track sections 280 and 282.

[0195] The housing lid 222 can now be moved parallel to the housing preferred axis 244 in the direction of the curved housing opening edge section 278 until the lid edge 308 abuts the can insert contact edge 266 and then the lid edge surface 310 also touches the edge support surface 264 in the region of the curved housing opening edge section 278. During this movement, the guide members 288 and the locking recesses 292 then engage, as already described.

[0196] Due to the asymmetrical design of the housing 218 with respect to the plane 286, the edge support surface 264 of the housing opening edge 248 is at least partially visible in the filter position in the region of the curved housing opening edge section 276, which touches the housing cover 222 when the guide members 288 and the guide grooves 256 come into contact. A directional arrow 314 is arranged in this visible region of the edge support surface 264, which is visible in the filter position and indicates a direction of displacement of the housing cover 222 relative to the housing 218 for transferring the filter insert 20 from the filter position into the insertion position. The housing preferred axis 244 is also defined by the housing opening 220. As described, the housing cover 222 resting on the edge support surface 264 can be displaced parallel or substantially parallel to the housing preferred axis 244, namely from the insertion position into the filter position.

[0197] The housing cover 222 is symmetrical with respect to both the plane of symmetry 84 and the plane 286.

[0198] The functionality of the table filter jug ​​is briefly explained below.

[0199] As already mentioned, the table water jug ​​10 is designed as a table water filter jug ​​12. For use, it must be prepared as schematically shown in Figures 1 and 2. The jug insert 16 is inserted into the provided jug container 14 as described above. The filter insert 20 can then be inserted into the jug insert 16. The jug insert 16 is closed with the lid device 18.

[0200] The table water filter jug ​​12 can be filled with water with the container lid 52 in place. To do this, the filling opening lid 92 is moved into the filling position. In the filling position, it is held by the locking device 106 so that it cannot automatically move into the closed position. Untreated water, for example directly from a faucet, can now be poured into the jug insert 16 through the filling opening 90. The added untreated water flows through the water inlets 298 on the housing cover 222 of the filter insert 20 into the latter and flows through the filter element 226. After flowing through the filter element 226, the now treated water exits the jug insert 16 through one of the water outlets 236 and flows into the jug container 14. There it collects and can be poured out of the jug container 14 through the spout 32.Once the filter element 226 is used up, the container lid 52 is removed from the can insert 16 and the filter insert 20 is removed by a user grasping the handle element 304 and thus lifting out the filter insert 20. To open the housing 218, the housing lid 222 is moved in the direction of the directional arrow 314 from the filter position to the insertion position. In the insertion position, the housing lid 222 covers the area of ​​the edge support surface 264 with the directional arrow 314. The guide members 288 are now each in a position in the transition area between the first and second track sections 280, 282. The housing lid 222 can now be lifted off the housing 218 by a movement in the direction of the first track section 280. The filter element 226 can now be removed from the housing receptacle 224 and replaced with a new, unused filter element 226.

[0201] To close the housing 218, proceed in reverse order. The filter insert 20 can then be reinserted into the jug insert 16. The guide ribs 208 ensure that the housing base 240 of the filter insert 20 is guided into the desired position, namely, that it can be inserted into the jug insert base opening 204 without jamming. Finally, the container lid 52 only needs to be placed on the jug insert 16. The tabletop water filter jug ​​12 is now ready to filter or demineralize untreated water again.

[0202] Figures 28 to 30 show a further embodiment of a lid device 18. It differs from the lid device 18 according to the embodiment of Figures 1 to 27 only in the design of the locking device 106. Therefore, only the differences between the two locking devices 106 are explained below. To designate identical or functionally similar elements and components, the same reference numerals are used as in the embodiment of Figures 1 to 27. In the embodiment of Figures 28 to 30, the holding strip 166 is somewhat shorter than in the embodiment of Figures 1 to 27. A locking element 318 in the form of a magnetic holding element 320 is arranged adjacent to a free end 316 of the holding strip 166, which points in the direction of the filling opening 90.The magnetic holding element 320 cooperates with the magnetic holding element 136 on the filling opening cover 92 in the closed position to hold and lock the filling opening cover 92 in the closed position in a defined manner. Figures 28 to 30 each show the cover device 18 in the closed position.

[0203] When the edge 102 rests against the stop 130 in the closed position, the magnet 140 is aligned above the magnetic holding element 320, which is also designed as a magnet 322. The magnets 140 and 322 are arranged such that in the closed position a south pole of one magnet is opposite a north pole of the other magnet, so that the two magnets 140 and 322 attract each other in the closed position. In the closed position, a greater magnetic holding force then acts between the two magnets 140 and 322 than between the magnet 140 and the holding strip 166. This greater holding force in the closed position is noticeable to the user. In order to move the filling opening cover 92 from the closed position to the filling position, the user must therefore apply a somewhat greater force to overcome the magnetic holding force between the two magnets 140 and 322.

[0204] In the embodiment of Figures 28 to 30, the holder 168 is slightly modified compared to the holder 168 in the embodiment of Figures 1 to 27. It has a magnet holder 324 facing the filling opening 90, into which the disc-shaped magnet 322 can be inserted. For this purpose, the magnet holder 324 is designed in a groove-like manner and is open toward the filling opening 90 for insertion of the magnet 322.

[0205] In this embodiment, a cover 172 is also provided, covering the holder 168. In this embodiment, the cover 172 is also glued or welded to the cover 88 to enclose the retaining strip 166 and the magnet 322 in a fluid-tight manner, thus protecting them from corrosion.

[0206] As explained, in the embodiment of Figures 28 to 30, the locking device 106 is only designed to lock the closed position.

[0207] Of course, the locking device 106 can also be designed so that locking is only possible in the filling position. In this case, the magnet 322 would have to be positioned adjacent to the retaining strip 166 at its free end facing away from the filling opening 90.

[0208] If locking by magnetic holding forces is desired both in the closed position and in the filling position, magnetic holding elements 320 must be positioned at both free ends of the holding strip 166 as described.

[0209] In the embodiment of Figures 28 to 30, the locking elements 110 and 318 are thus engaged by magnetic interaction.

[0210] For the sake of clarity, it should be noted that in the embodiment of Figures 28 to 30, no locking knobs 122 are arranged or formed on the guide receptacle edge 118 of the guide receptacle 116. Thus, in this embodiment, no mechanical locking can occur in the filling position and the closed position. Of course, it is conceivable to mechanically lock the position that is not locked by magnetic interaction, as explained in detail in the embodiment of Figures 1 to 27.

[0211] Figures 31 to 34 schematically illustrate a further embodiment of a lid device 18. It again differs from the embodiment of Figures 1 to 27 only in the design of the locking device 106. In the embodiment of Figures 31 to 34, no locking knobs 122 are arranged or formed on the guide receptacle edge 118 of the guide receptacle 116. Nevertheless, in this embodiment too, locking of both the closed position and the filling position is achieved purely mechanically. In this embodiment, the sliding elements 96 form locking projections 326. A total of four sliding elements 96 and thus four locking projections 326 are provided. Two locking receptacles 328 interact with the locking projections 326, which are formed on the lid 88 in the form of sliding surface recesses 330 in the sliding surface 104.

[0212] The functioning of the locking device 106 in the embodiment of Figures 31 to 34 will now be briefly explained.

[0213] When the filling opening cover 92 assumes the closed position, two of the four locking projections 326 engage the locking receptacles 328. To move the filling opening cover 92 into the filling position, the filling opening cover 92 must be moved away from the filling opening 90, as in the other exemplary embodiments. For this purpose, a somewhat increased force must be applied to disengage the locking projections 326 and the locking receptacles 328. Once these are disengaged, the four sliding elements 96 slide on the sliding surface 104, as in the other two exemplary embodiments, until the filling opening cover 92 reaches the filling position.

[0214] The sliding elements 96 are positioned on the filling opening cover 92 such that the other two sliding elements 96 can now snap into the locking receptacles 328 on the cover 88. This snapping or engaging of the filling opening cover 92 on the cover 88 is noticeable to the user. To move the filling opening cover 92 back into the closed position, the procedure must be reversed. Here, too, additional force must first be applied to disengage the locking projections 326 and the locking receptacle 328.

[0215] The lid devices 18 of the exemplary embodiments of Figures 1 to 27, Figures 28 to 30, and Figures 31 to 34 can optionally be connected to the described jug insert 16. The functionality of the table water jug ​​10 otherwise remains unchanged, so reference can be made to the above description.

[0216] The described embodiments of table water jugs 10 enable the simple treatment of water, especially tap water. Furthermore, they are designed for sustainability, because in the described table water jugs 10, used filter elements 226 can be replaced without also having to replace the housing 218 and the associated housing cover 222. Thus, the filter insert 20 is reusable, except for the filter element 226. Therefore, only the component that is actually no longer usable needs to be replaced.
