Description

Technical Field

[0001] The present invention relates to a closed unit having the features of the preamble of claim 1 for connection with a drinking bottle or a cup, especially a thermos. Background Technology

[0002] DE 20 2017 100 771 U1 discloses a bottle closure for an insulated container of hot beverages. DE 10 2019 128 302 B3 describes a bottle closure for a drinking bottle with a narrow neck. Both solutions share the characteristic of providing a high degree of sealing due to their two independent sealing levels. This results in high spill-proof safety not only when the container is tilted but also in the case of carbonated beverages that cause high internal pressure. Furthermore, leakage of any remaining liquid after the closure is closed is prevented. The only drawback of this highly developed bottle closure is that it requires two hands to operate and / or a large force to press the actuation button. The actuation button for opening or closing the bottle closure must always be actuated directly against the spring force, whereby the spring force must be so large that there is a sufficiently large clamping pressure on the sealing element's abutment surface and the sealing effect is maintained in all positions of use. Therefore, it can be operated with one hand only for a person who holds the bottle on the sealed part of the bottle and can also press the actuation button at the same time.

[0003] This type of sealing unit is known from CN 205114003 U. This sealing unit is advantageous in terms of ergonomics because the pouring element is positioned upwards and therefore easily accessible during drinking. However, the pouring element is more precisely a drinking nozzle that must be surrounded by the lip, rather than a pouring element with a pouring edge where the lip simply needs to be placed for drinking. Furthermore, the base element and the pouring element are only sealed relative to each other at the upper, retracted position of the pouring element. Therefore, residual liquid may accumulate and reach the space below the cap through the sealing element that closes the pouring opening. This space is not liquid-tightly sealed. Therefore, contamination may occur if the drinking bottle with the sealing unit is transported flat in a bag after use. Summary of the Invention

[0004] Therefore, the object of the present invention is to provide a sealing unit for connection with a drinking bottle or a cup, which enables easy one-handed operation.

[0005] This objective is achieved by a closed unit having the features of claim 1.

[0006] The use of closure units is described below, particularly in connection with drinking bottles. This includes both insulated and non-insulated drinking bottles, drinking cups, or other beverage containers. As is common in known closure units for insulated bottles, insulated cups, and portable beverage containers, a pouring element is provided with a pouring edge that surrounds at least one pouring opening, which can be closed by a sealing element.

[0007] However, in the closure element according to the invention, the pouring element is not directly connected to the drinking bottle or cup, but is provided with an additional base element arranged between and securely connected to the drinking bottle or cup. The pouring element is movably supported and guided in the base element, so that the pouring element can be displaced along or parallel to the central axis of the closure unit and thus can be lifted from the base element. At least one spring element is provided to lift the pouring element from the base element.

[0008] According to the invention, single-handed operation of the closure unit is facilitated by the presence of a pivotable cover that overcomes the large spring force required to establish a seal in the closure unit according to the invention. However, pivoting can be comfortably performed by placing one or more fingers on the upper side of the cover, which is easier than pressing the center actuation button axially downwards, especially when the closure unit is held with the same hand simultaneously.

[0009] During the opening movement, the cover slides on the edge of the elastically supported outlet element. Only sliding friction needs to be overcome here. During the closing movement, the cover slides again onto the edge of the elastically supported outlet element. Here, in addition to overcoming sliding friction, the spring element must also be pre-tensioned. Because the pivotally supported cover pivots at a large radius and the gradually increasing spring tension during closing is maintained at each intermediate position by the cover firmly supported at the base element, a less force can be used to perform the one-handed closing movement compared to known closing units with a centrally actuated button.

[0010] The sealing of the discharge opening is achieved by pressing the movable discharge element against the base element, thereby pressing at least one sealing element present on the discharge element or the base element against at least one discharge opening on the corresponding other element. If the discharge element is lifted again by spring force, the seal is also released.

[0011] Here, the sealing element can be securely arranged in the base element so that the discharge opening of the discharge element is closed when the discharge element descends onto the base element.

[0012] As an alternative, a sealing element can be securely arranged in the dispensing element so that the dispensing opening on the base element is closed when the dispensing element descends onto the base element.

[0013] The user must close the cover to overcome the force of the spring element engaged therein and press the dispensing element against the base element. The spring element is pre-tensioned here so that if the cover is later pivoted away and no force is applied, the dispensing element will automatically lift off the base element.

[0014] Therefore, a stop device is also provided to hold the dispensing element in a descending position relative to the base element, overcoming the force of the pre-tensioned spring element. Preferably, the stop device is formed together with a cover portion, which can simultaneously cover the upwardly open area of ​​the dispensing element and thus protect it from contamination.

[0015] A particular advantage of this invention lies in the spring element constructed in the form of a flexible hose segment and made of elastomeric plastic, especially silicone. This allows for the simultaneous achievement of several advantages: - The silicone spring element stores enough spring energy in the compressed state to lift the pouring element from the base element again later, even if there is local adhesion due to residual beverage; - The spring element is food-grade and can come into direct contact with the beverage liquid. Specifically, a sealing channel is constructed by this flexible spring element positioned between the base element and the pouring element, which surrounds the sealing element, the pouring opening of the base element, and the pouring opening of the pouring element. The silicone spring element forms a deformable, variable-length portion of the flow path between the base element and the upwardly movable pouring element, which is the part of the closure unit securely connected to the beverage container.

[0016] The spring element is connected at its end to the lower side of the discharge element and the upper side of the base element, so that once the sealing element abuts against the discharge opening, a space that is completely closed outward is formed within the sealing element.

[0017] Alternatively, it is feasible to manufacture the sealing element and the elastomeric spring element for closing the pouring opening in one piece, for example, by providing an outer wall and a sealing element for closing the center of the pouring opening, wherein the outer wall stores spring force when the pouring element and the base element approach each other, and the sealing element is attached to the outer wall by radial spokes.

[0018] It is also conceivable to provide only a single sealing element for closing the center of the pouring opening, which is itself compressible and can therefore also function as a spring element.

[0019] Alternatively, it is feasible to reinforce the elastomeric spring element with a helical compression spring. An additional helical compression spring is particularly advantageous if residual sugary beverages cause adhesion between the folds of the compressed elastomeric spring element, making the restoring force achievable solely through the sealed channels of the elastomer insufficient.

[0020] In the first embodiment, the cover includes only one cover element, which is connected to the base element via a pivot. This cover element can pivot away from the side, thereby expanding the spring element and lifting the dispensing element, thus releasing the dispensing opening.

[0021] In order to enable pivoting, the contours of the upper edges of the base element and the pouring element are adapted to the pivoting trajectory that slopes from top to bottom and are tilted toward the side toward which the cover element pivots.

[0022] Alternatively, the cover may include a clamp and a cover element, the clamp being pivotally supported on a base element and the cover element itself being movably supported on the clamp. To hold the cover element on the upper side of the closure unit and prevent unwanted pivoting of the clamp, the cover element may have an actuation button with at least one cam on its underside, the cam being form-fitted onto the inner edge of the pouring edge at the closed position of the closure unit.

[0023] Furthermore, it is advantageous to guide the movement of the pouring element within the base element. For this purpose, at least one inlet pipe is provided, which surrounds the pouring opening of the pouring element and connects to the underside of the pouring element. Additionally, the inlet pipe extends through a sealing channel (if present) and through at least one pouring opening of the base element until it enters the area of ​​the neck of the drinking bottle or cup.

[0024] Specifically, the inflow nozzle is formed by multiple segments, each of which extends through a portion of the outlet opening of the base element.

[0025] Another advantage is that at least one of the segments has a removable form-fitting fixing portion between it and the base element, which limits the displacement stroke of the dispensing element. This can be achieved by having at least one segment elastically attached to the dispensing element, and at least one protrusion formed on the segment, which form-fits into a recess on the base element or below a recess on the base element.

[0026] Furthermore, it can be specified that the inlet connector has a pair of tabs at at least two radially opposite positions on its inner wall, with a fluid-guiding chamber constructed between the tabs. The tabs extend radially inward to the outer circumference of the sealing element, thus constructing a centrally open chamber. This allows liquid to be guided through one chamber and air through another during drinking, resulting in a uniform liquid flow and preventing surging liquid outflow.

[0027] In the case of a cup with a larger cross-sectional area covered by a base element, it is advantageous to have a vent pipe with a vent opening located away from the pouring opening, and a vent sealing element tightly fastened to the underside of the pouring element. When the pouring element descends onto the base element, the vent opening in the base element automatically closes.

[0028] An advantageous embodiment of the invention specifies that the cap is designed such that the fitting can be form-fitted to and released from the cap without adversely increasing the structural height of the cap or creating openings in the cap through which residual liquid could drain or contaminants could enter. The sealing unit provides at least one mating area in which the coupling element of the fitting can be form-fitted to and released from the cap without adversely increasing the structural height of the cap or creating openings in the cap through which residual liquid could drain or contaminants could enter, even if no coupling element is inserted in the mating area.

[0029] Therefore, the following is specifically stipulated: - The cover has a mating area for fastening fittings, through which a cover wall with at least one recess is passed. A coupling element can be inserted into the recess for fastening the fittings, and the coupling element can be form-fitted to the cover by rotational movement; and - An elastic diaphragm is arranged below the recess, which covers the recess. The diaphragm is designed such that it shifts due to elastic deformation when the coupling element is introduced into the recess and abuts against the coupling element after a rotational motion is performed.

[0030] The component, made of an elastomeric material, is considered a diaphragm. This component preferably has a small thickness relative to its planar extension to allow for easy deformation, and it is preferably fastened to the cover at its edge. The deformability should be chosen to allow the coupling element to be inserted into the recess without requiring significant force. The planar extension of the diaphragm is at least large enough that the recess and the edge region surrounding it are completely covered. Preferably, the diaphragm is designed like a rubber sheet with a layer thickness of 1 mm to 2 mm in the annular region between the central recess and its edge fastening portion.

[0031] The diaphragm ensures that the recess required for the conductive coupling element always remains closed toward the interior space of the cover, and more precisely, regardless of whether the coupling element is actually inserted.

[0032] The main advantage of the embodiment with a mating area for fittings is that, since the mating area is provided by covering the recess with a diaphragm, it does not visually interfere with the fit, and the mating area does not require any additional structural height in the cover. Therefore, the mating area can also be provided in a very flat cover structure.

[0033] Since the installation of the accessories is carried out through the combined insertion and rotational movements of the coupling elements, the removal is also carried out in the same way. After the accessories are installed, the pre-tightened diaphragm abutting against the coupling element below is additionally fixed by friction, so that additional, difficult-to-overcome locking connectors are not required in the shape-fit connection between the coupling element and the cover, so as to fix the installed accessories to the closed unit.

[0034] In addition, it can be stipulated that: - The cover has a receiving bracket below the recess, the diaphragm is held in the receiving bracket, and the coupling element or its components can be form-fitted in the receiving bracket by rotational movement; - A closure element is provided, which is connected to an elastic diaphragm, and the closure element is placed within the circumference of the recess as long as no coupling element is inserted; - The sealing element and the diaphragm are constructed as a single piece; - The diaphragm has at least one pin on its underside, which is also formed of an elastomer, and the diaphragm uses the pin to support itself on other sturdy components in the cover; - The diaphragm has at least one deformable pin on its underside, which is also formed of an elastomer and / or constructed as a single piece with the diaphragm, and the diaphragm uses the pin to support itself on other robust components in the enclosed unit. - The closure unit includes at least one fitting that can be coupled in the docking area, the fitting having a coupling element having a locking element that can be guided through the recess and engaged under the cover after rotational movement; - The recess and the locking element are both elongated holes, and the receiving bracket has a guide groove for the locking element, in which the locking element is rotatably guided at an angle of less than 360°; - Similarly, the elongated sealing element is connected to or formed onto the diaphragm, and the guide groove is configured such that the locking element, which is guided through the recess, can rotate 90° until it enters the end position, where the sealing element is arranged transversely to the locking element and the locking element has a gap on its underside, into which the sealing element is fitted. - Accessories include retaining loops or rings that connect to the coupling element.

[0035] Advantageous implementation methods relating to feasible solutions for the installation of accessories are described in more detail below.

[0036] Because the docking area is advantageously positioned at the center of the cylindrical cap, the receiving support for the diaphragm can remain completely beneath the lower side of the cap. With the cap closed, only a few sections protruding downwards from the cap wall are within the deepened area surrounding the dispensing opening, enclosed by the dispensing edge on the sealing unit.

[0037] The coupling element can be used, for example, to mount a retaining loop or retaining ring. This facilitates the portable use of a drinking bottle equipped with the closure unit according to the invention. The coupling element can also be securely connected to a backpack to secure the drinking bottle, drinking cup, or other beverage container to it. Furthermore, decorative elements such as toy figures can be attached to the cap via the coupling element.

[0038] Preferably, the diaphragm includes a closure element on its upper side, the closure element being formed such that when the diaphragm is in a relaxed initial state, the closure element is engaged from below into a recess in the cover. The recess can be closed above, such that the closure element is flush with the outer surface of the cover and visually appears only as a decorative element. If a coupling element is introduced into the recess, the closure element springs open, wherein the diaphragm elastically expands. Preferably, the closure element and the diaphragm are constructed as a single piece. However, the closure element may also be a rigid plastic component connected to the diaphragm, for example, by adhesive.

[0039] According to another embodiment of the invention, the closure element on the diaphragm is fitted from below into the opening in the locking element, causing an additional form-fit connection. This additional form-fit connection prevents accidental twisting of the coupling element. The additional form-fit connection is released by elastic deformation, i.e., by the user rotating the coupling element in the opposite direction to the unlocked position.

[0040] According to another embodiment, the recess in the cover and the locking element are both elongated holes, wherein their outlines are similar in geometry. A gap is left between the outer contour of the locking element and the inner contour of the recess. The locking element is inserted through the recess and fitted into a receiving bracket below the recess. The form-fit connection is achieved by a 90° rotational movement of the coupling element. Here, the locking element is guided in a guide groove in the receiving bracket until it abuts against a fixed stop that limits the angle.

[0041] A connection can also be established by rotating the locking element at a larger angle; however, this angle should be less than 360° so that a fixed stop can be set so that the locking element occupies an angular position relative to the cover element, at which a durable, form-fit connection is ensured.

[0042] In another preferred embodiment, the fitting includes a coupling element comprising a disc-shaped support plate and a connecting pin below it, which is radially reduced in size compared to the support plate. A locking element is connected to the connecting pin and has an elongated, hole-shaped outer profile. A guide cam is located on the upper side of the locking element, which guides the fitting during rotation for a form-fitting fixation in the cover.

[0043] Furthermore, it is advantageous that the diaphragm has at least one particularly centrally located pin on its underside in the region of the closure element located above it. This pin is also formed of an elastomer, and the diaphragm uses this pin to support itself on another robust member within the cover. Thus, the diaphragm can be held in the recess by the closure element not only due to its internal stress, but also by the pin pushing the attachment upwards. Once the coupling element is inserted from above, the pin compresses or bends, thereby maintaining the diaphragm's free movement during coupling.

[0044] As an alternative or additional solution, such support can be achieved by having at least one downwardly extending crimp on its underside in the region of the outer edge of the diaphragm, the crimp also being formed of an elastomer, and the diaphragm using the crimp to support itself on another sturdy member in the cover.

Detailed Implementation

[0046] Figure 1A sealable insulated mug is shown in perspective. The mug consists of an insulated, cup-shaped beverage container 200 and a closure unit 100 screwed onto the beverage container 200. The closure unit 100 includes a base element 20 and a pivotable cover 30. The base element 20 is directly connected to the beverage container 200, and the cover 30 is pivotally connected to the base element 20 via a pivot shaft 31.

[0047] Figure 2 Another perspective view shows the insulated cup consisting of a beverage container 200 and a sealing unit 100. The cover 30 pivots downward about the pivot axis 31.

[0048] As the covering portion 30 pivots, the pouring element 10, which is elastically supported within the base element 20 in a form-fitting manner, is no longer pivoted. As a result, the pouring element 10 is pushed vertically upward by the force of the spring acting between the base element 20 and the pouring element 10.

[0049] As in Figure 2 As can also be seen, the pouring element 10 has a distinctive profile for the pouring edge 12. On the side facing away from the cover portion 30, the pouring edge 12 extends in a horizontal plane with its upper edge, and its central axis extends relative to this horizontal plane as a normal. Conversely, the upper edge of the pouring edge 12 slopes on the side facing the cover portion 30 and follows the pivoting trajectory of the cover portion 30. This allows the cover portion 30 to slide on the pouring edge 12 when it is later closed, and here again overcomes the force of the internal spring element to press the pouring element 10 deeper into the base element 20.

[0050] If the cover portion 30 is in the closed position shown in the figure, the resiliently supported pouring element 10 is also held in its lowered position. Therefore, the cover portion 30 forms a stop device.

[0051] Figure 3 This is an exploded perspective view of the beverage container 200 together with the closure unit 100. The pouring element 10 and its pouring edge 12 are visible in the upper region. The pouring element 10 has a downwardly projecting inlet pipe 11. The base element 20 has a tab 22 with an upper edge whose contour extends similarly to the upper edge of the pouring edge 12 on the pouring element 10, so that when the pouring element 10 descends into the base element 20, the two together form a unified edge.

[0052] The base element 20 has a bearing 21 for the pivot shaft of the cover portion 30. The neck seal portion 55 is engaged between the neck 210 of the beverage container 200 and the base element 20 to seal the connection between them.

[0053] The mushroom-shaped sealing element 51 is securely positioned in the base element 20 and is used to seal the discharge opening in the discharge element 10. The sealing element 51 is made of an elastomeric material.

[0054] In addition, a spring element 52 is provided, which is also made of an elastomeric material, particularly silicone, and has the shape of a short hose section. A sealed channel is constructed within the spring element 52, through which the inlet pipe 11 of the base element is guided. Furthermore, the spring element 52 can be axially compressed along its central axis, thereby causing elastic deformation. Once the cover 30 pivots laterally away, this elastic deformation enables the outlet element 10 to be vertically lifted relative to the base element 20.

[0055] Another elastomeric component is a vent sealing element 16, which is fastened to the underside of the discharge element 10 and closes the vent opening in the base element 20 (not shown here) when the discharge element 10 descends onto the base element 20.

[0056] Figure 4 The components before assembly are shown in a three-dimensional cross-sectional view. The base element 20 has a largely cylindrical outer profile and a cover region 23 that engages at approximately half its height. The outer profile has an upwardly projecting cylindrical tab 22, and the cover region 23 encloses the cross-section within the tab 22. The tab 22, which extends upward beyond the cover region 23, mates with the outer diameter of the ejector element 10.

[0057] A sealing element retainer 24 is formed in the cover region 23, in which the sealing element 51 is held. The sealing element retainer 24 has spokes or laterally extending load-bearing bridging members to hold the sealing element 51 in the center, wherein the spokes or load-bearing bridging members extend over the discharge opening without completely closing the discharge opening.

[0058] In the lower region, the base element 20 has a threaded section 29 with internal threads, through which the base element 20 is screwed onto the neck section 201 of the beverage container 200. Here, the neck seal 55 compresses and seals the connection between the base element 20 and the upper edge of the neck section 201.

[0059] A spring element 52 is visible on the base element 20, which forms a sealing channel 53 within its internal space through which the inlet pipe 11 extends. An outlet chamber 14 is located at the upper end of the inlet pipe 11, the cross-section of which is larger than the cross-section of the outlet opening 15. The outlet element 10, in addition to the surrounding outlet edge 12, also has a cover region 13 that covers the cross-section within the outlet edge 12. A receiving portion for a vent sealing element 16 is provided on the lower side of the cover region 13. This vent sealing element 16 is pressed from above onto a vent pipe 26 on the base element, which has an internal vent opening.

[0060] Figure 5 The assembled, closed beverage container along with the sealing unit is also shown in a three-dimensional cross-sectional view. The sealing unit 100 is screwed onto the beverage container 200. The dispensing element 10 is in a lowered position relative to the base element 20. As a result, the spring element 52 is compressed and the venting sealing element 16 is placed on the venting pipe 26. The sealing element 51, with its mushroom-shaped head 51.1, presses against the dispensing chamber 14 on the dispensing element 10 from its upper side.

[0061] The covering portion 30 supplements the outer contour of the closed unit 100 as specified by the tab 22 and covers the open area of ​​the pouring element 10 on the upper side.

[0062] The inlet pipe 11 consists of multiple segments that extend through the pouring opening in the cap area of ​​the base element 20 until they enter the beverage container 200.

[0063] Figure 6 The opening process of the closure unit 100 is illustrated. A male or female user applies force to the cover 30 perpendicular to the central axis with their thumb 1, causing the cover 30 to lift from the upper edges of the tab 22 and the discharge edge 12. The cover 30 undergoes a pivoting movement toward the side due to its connection to the base element 20 on the pivot bearing. As the cover pivots away, the discharge element 10 is no longer fixed to the base element 20, and once the spring element 52 can re-expand, the discharge element 10 is pushed upward by the spring energy stored in the spring element 52 during the aforementioned compression. As the discharge element 10 is pushed upward, the contact between the mushroom-shaped head of the sealing element 51 and the discharge chamber 14 is also released, thereby releasing the discharge opening 15. Simultaneously, the vent sealing element 16 is lifted from the vent pipe 26.

[0064] Figure 7A three-dimensional cross-sectional view of the opened closure unit 100 together with the beverage container 200 is shown. The spring element 52 is fully expanded, and the dispensing element 10 is raised to its maximum height relative to the base element 20. Lines with arrows in the left region indicate flow from the beverage container 200 into the inlet pipe 11. This flow occurs through a dispensing opening located around the sealing element 51 in the cap region 23 of the base element 20 and ultimately through the dispensing chamber 14 and the dispensing opening 15 into the upper region on the dispensing element 10 defined by the dispensing edge 12.

[0065] Figure 8 This illustrates how the base element 20 and the discharge element 10 can be separated from each other for cleaning purposes. To do this, the inlet pipe 11, which consists of multiple segments, is radially compressed, thereby releasing the form-fitting fixation of the inlet pipe 11 in the base element 20, allowing the discharge element 10 to be pulled upwards.

[0066] The cover portion 30 is designed so that it does not obstruct the removal of the pouring element 10 from the base element 20 when it is in its lowered position.

[0067] Figure 9 Another embodiment of a closure unit 100' for an elongated drinking bottle 200' is shown in a perspective view. The closure unit 100' includes a base element 20' and a cover portion 30', the base element 20' being directly connected to the drinking bottle 200'. The cover portion 30' has a clamp 33' and a cap element 32', the clamp 33' being pivotally connected to the base element 20' via a pivot axis 31', and the cap element 32' itself being hinged to the clamp 33'. An unlock button 34' is integrated into the cap element 32'.

[0068] Figure 10 Another perspective view shows the assembly consisting of the drinking bottle 200' and the sealing unit 100' in the open position. The clamp 33' pivots downward about the pivot axis 31', thereby moving the cap element 32' away from the upper side of the base element 20'. Consequently, the pouring element 10', no longer form-fitted and elastically supported within the base element 20', is pushed vertically upward by the force of a spring acting between the base element 20' and the pouring element 10'. The area surrounded by the pouring edge 12' is now exposed. The pouring opening 15' therein is open. The sealing element 51' is visible therein.

[0069] Figure 11Components of an alternative closure unit 100' for an elongated drinking bottle 200' are shown. The closure unit 100' includes a base element 20' and a cover 30', which is pivotally fastened to the base element 20' on a bearing shaft 31'. The closure unit 100' also includes a pouring element, not shown here.

[0070] In the lower region of the base element 20', a threaded section 29' is constructed for connection with the elongated neck of the drinking bottle. For this purpose, the base element 20' tapers upward from the threaded section 29' toward the outlet opening 25'. The support bridging member 27' holds the sealing element retainer 24' for securing the sealing element 51' to the center of the outlet opening 25'. The sealing element 51' has a mushroom-shaped head 51.1' on the upper side of its stem and a flange 51.2' that widens circumferentially on the lower side of its stem.

[0071] The cover region 23' between the pouring edge 22' and the pouring opening 25' is constructed to be very narrow in the example shown for the closing unit 100' and is limited to the groove range for receiving the cylindrical spring element.

[0072] Figure 12 The completed assembly of the closure unit 100' in the closed position is shown. The upper section of the drinking bottle 200' with the neck portion 201' is visible in the lower region. The base element 20' is screwed onto the neck portion 201' with its threaded section 29'. The neck seal portion 55' engaged therebetween provides a seal between the two elements.

[0073] A cover 30' is placed in the area above the closing unit 100', and the cover 30' covers the area of ​​the dispensing element 10' surrounded by the dispensing edge 12'. The cover element 32' is supported on a clamp 33', which is in turn pivotally supported on a base element 20', as previously referenced. Figure 11 As described.

[0074] The cover 30' has an actuation button 34', which has a cam 35' on its underside. The cam 35' is supported on the inner edge of the pouring edge 12' and is thus shaped-fitted and secured. The clamp 33' cannot pivot in the position shown because the cover element 32' is pressed to the left in the pivoting direction against the upper edge of the tab 22', and the cam 35' abuts against the pouring edge 12' in the opposite direction.

[0075] A sealing element 51' is inserted into a sealing element holder 24'. An outlet element 10' is inserted into the space within the tab 22' of the base element 20'. This outlet element 10' surrounds an upwardly open space with an outlet edge 12', and an outlet opening is present on the lower side of this space. Figure 10The location shown is closed by the mushroom-shaped head 51.1' of the sealing element 51'.

[0076] An elastomeric spring element 52' made of silicone is inserted between the base element 20' and the dispensing element 10'. This spring element 52' is formed as a hose segment. The spring element 52' forms a sealing channel 53' within itself, which surrounds the area of ​​the dispensing opening in the base element 20' and the inlet pipe 11' of the dispensing element 10', thereby liquid-tightly sealing the entire intermediate space between the base element 20' and the dispensing element 10'. For this purpose, not only the upper edge region of the spring element 52' but also the lower edge region is sealed and pressed into the annular groove in the base element 20' or the dispensing element 10'.

[0077] The inlet pipe 11' extends through the area of ​​the outlet opening in the base element 20' that is not blocked by the load-bearing bridge 27' used for sealing element 51'. In order to bypass the load-bearing bridge 27', the inlet pipe 11' is divided into multiple segments, one or more of which extend through the segment of the outlet opening.

[0078] Figure 17 The base element 20' is shown from below. The outflow opening 25' is divided into two parts by the load-bearing bridge 27' and the sealing element retainer 24'.

[0079] Figure 16 The discharge element 10' is shown below. An outlet opening 15' is located at the center of the base element 10'. The inlet connector 11' is, in this case, composed of two segments 11.2' and 11.3', with a spacing on each side between the segments 11.2' and 11.3', in which the carrier bridging member of the base element can be received. Segment 11.2' is rigidly connected to the base element 10', while the other segment 11.3' is elastically mounted on the base element, allowing it to be pressed inward toward the center. The tabs 11.1' on the inner sides of segments 11.2' and 11.3' extend slightly inward radially, and more precisely, to such an extent that the mushroom-shaped head of the sealing element can be positioned in the center. Chambers 11.4' are constructed between each pair of tabs 11.1'. This allows liquid or air to be guided through the mushroom-shaped head. Because multiple chambers 11.4' are constructed circumferentially, especially at at least two radially opposite locations, the outflowing liquid and the subsequent airflow can be guided in separate flow paths. The typical gurgling sound that occurs when drinking from a bottle with a narrow neck is avoided in the enclosed unit 100'.

[0080] exist Figure 13The diagram shows the beginning of opening the closure unit 100'. This opening is initiated by pressing down on the button 34'. This disengages the cam 35' from the pouring edge 12' and thus unlocks the device formed by the stop formed by the cover 30'. The clamp 33' can now be pivoted in the direction indicated by the arrow.

[0081] exist Figure 14 The fully opened closure unit 100' can be seen. Clamp 33' pivots downwards to its maximum extent, thereby simultaneously bringing the cover element 32' to a lateral position on the base element 20'. Due to the pivoting of the cover 30', the spring element 52' expands, thereby pushing the outlet element 10' vertically upwards, thus creating an increased gap between the outlet element 10' and the base element 20'. Due to the movement of the outlet element 10', the central sealing element 51', with its mushroom-shaped head 51.1', moves away from the outlet opening 15' and releases it.

[0082] A sealing channel 53' is continuously formed within the spring element 52', which completely seals the area defined upward and downward by the base element 20' and the outlet element 10'. The inflow pipe 11' is guided through the sealing channel 53'.

[0083] Figure 15 This illustrates how the pouring element 10' can be removed vertically upwards. The segments 11.2' and 11.3' of the inlet pipe are pressed against each other. A protrusion 11.5' is formed on segment 11.3', which engages below the cover segment 23'. Once the protrusion 11.5' pops out, the form fit is released, and the pouring element 10' can be pulled out from the base element 20'.

[0084] exist Figure 18 In the diagram, the pouring element 10' along with the silicone hose is removed from the base element 20'. The silicone hose serves as the spring element 52' and forms the sealing channel 53'.

[0085] Figure 19 A fitting 60 for closing the unit is shown. Besides retaining the latch 64, the fitting 60 includes a coupling element 61 comprising a disc-shaped support plate 63 and a connecting pin 62 below it, which is smaller in diameter than the support plate 63. A locking element 65 is connected to the connecting pin 62 and has an elongated, perforated outer profile. A recess 66 is present on its lower side, and a guide cam 67 is present on its upper side, which induces guidance during rotation for form-fitting fixation in the cover.

[0086] exist Figure 20 The image shows the cover 30'' together with the coupling accessory 60. The cover 30'' basically corresponds to... Figures 1 to 8The embodiment shown, however, has a mating area 80 on its upper side and an annular area extending around it, forming an unlocking button 34'', allowing the cover to be pivotally rotated away from its locked position. The mating area 80 is here constructed within a cover housing, which is manufactured as a separately manufactured component element. Different types of cover housings allow the cover 30'' to be constructed with or without the mating area 80 as an option for connection with the accessory 60.

[0087] The mating area 80 has a centrally located elongated recess 81, which is surrounded by a receiving bracket 82. An elastic diaphragm 70 is tightly fitted in the receiving bracket 82 below the recess 81. The diaphragm 70 rests against the mating area 80 from below with its edge region and covers the recess 81 with its central region.

[0088] The arrows indicate the movements required for coupling the fitting 60: first, downward movement to guide the connecting pin 62 through the recess 81 into the receiving bracket 82, and rotational movement to secure the locking element 65, shaped below the connecting pin 62, to the cover. Removal is performed in the reverse order.

[0089] Figure 21 The accessory 60, already connected to the cover 30, is shown. Figure 22 The marked area is shown in magnification.

[0090] The coupling element 61 rests on a shoulder in the mating region 80 with the edge of its support plate 63, which surrounds the recess 81. The locking element 65 is located in the receiving bracket 82 below it. The elastic diaphragm 70 deforms due to the inserted locking element 65.

[0091] Figure 23 The components of cover 30'' are shown below. Two guide rails, each extending from recess 81, are constructed on the underside of the mating area 80 and include guide cam 67 of coupling element 61 (see below). Figure 19 The coupling element 61 is fitted there and specifies a feasible rotation angle that the coupling element 61 can rotate relative to the mating area 80. A stop element 84 is formed near the end of the guide track of the guide groove 83, and the locking element 62 collides with the stop element at its end position, thereby similarly defining the rotation angle.

[0092] Figure 24 The closed element 100´´ is shown in cross-section, which is similar to Figures 1 to 8 The closed unit 100 shown has a reference. Figures 20 to 23 The described cover is 30´´.

[0093] The base element 20´´ has a largely cylindrical outer profile and a cap region 23´´ that engages at approximately half its height. This outer profile has an upwardly projecting cylindrical tab 22´´, which encloses the cross-section within the tab 22´´. The tab 22´´, extending upward beyond the cap region 23´´, mates with the outer diameter of the pouring element 10´´. A sealing element retainer 24´´ is formed in the cap region 23´´, holding the sealing element 51´´. In the lower region, the base element 20´´ has a threaded section 29´´ with internal threads, through which the base element can be screwed onto the neck section of the beverage container. The neck seal 55´´ is used to seal relative to the beverage container. On the base element 20', a flexible, tubular spring element 52'' can also be seen. This spring element 52'' has a sealed channel 53'' constructed within its internal space, through which the inlet connector 11'' extends. An additional helical pressure spring 56'', made of stainless steel wire, reinforces the elastomeric spring element 52''. The outlet element 10'' is in a lowered position relative to the base element 20''. Thus, the spring elements 52'' and 56'' are compressed.

[0094] An outflow chamber 14'' is located at the upper end of the inflow connector 11'', the cross-section of which is larger than the cross-section of the pouring opening 15''. The pouring element 10'' also has a cover region 13'' in addition to the surrounding pouring edge 12'', which covers the cross-section within the pouring edge 12''. A sealing element 51'' with its mushroom-shaped head presses against the upper side into the pouring chamber 14'' on the pouring element 10''.

[0095] A ventilated sealing element 26'' with a through hole serving as a vent opening is mounted on the base element 20''. A vent pipe 16'' is provided on the underside of the cover area 13'', which is inserted into the ventilated sealing element 26'' when the cover 30'' is closed.

[0096] Figure 25 The sequence of movements is shown when the accessory unit 60 is removed from the cover 30''. In the left-hand illustration, the accessory unit 60 is secured in the mating area 80 on the cover 30''. A portion of the coupling element 61 is positioned above the upper side of the cover 30''.

[0097] In the middle illustration, the fitting unit 60 is rotated 90° relative to the cover 30''. As a result, the elongated locking element is now positioned directly below the similarly shaped recess.

[0098] As shown on the far right of the figure, this cancels the shape-fit connection and allows the locking element 65 of the coupling element 61 to be pulled out. The recess 81 is immediately closed by the diaphragm 70.
