Description

[0001] The invention relates to a pouring device. Such a pouring device comprises a spout that is connected to, or at least connectable to, a container and that has a hollow pouring spout with a dispensing opening. The hollow pouring spout serves as a dispensing channel or also for filling the container.

[0002] The pouring device further comprises a cap with which the pouring spout is closed in its original state. The cap wall extends circumferentially around a pivot axis passing through and around the pouring spout, and axially along the pivot axis between a cap lid at the upper end and a cap rim at the lower open end. The open end of the cap rests on the pouring spout and surrounds it in its original state or later when closed.

[0003] Furthermore, the pouring device comprises a first locking element on the outer surface of the pouring spout and at least a second locking element on the inner surface of the cap wall, by means of which the cap and the pouring spout can be separated from each other by rotating the cap about the axis of rotation. Such locking elements can be formed, for example, by respective threaded sections, such as at least one external threaded section on the pouring spout and at least one internal threaded section in the cap. It is also possible to implement other types of interacting locking elements, such as at least one bayonet lug, particularly in the cap, and at least one guide cam, particularly on the pouring spout, if the connection between the cap and the spout is realized via a bayonet connection.

[0004] Preferably, such cooperating closure elements are provided which, during an opening rotary movement, cause the closure cap to be moved away from the spout in the axial direction of the axis of rotation, and during a closing rotary movement cause the closure cap and spout to be brought closer together, in particular until the seal is tight.

[0005] The dispensing device further comprises a tamper-evident feature, which is arranged and, in particular, attached to the cap in the area of ​​the cap rim, especially at the open end, preferably as a single piece, particularly in injection molding. Such a tamper-evident feature is provided to distinguish the dispensing device from its original, sealed state (original state), especially after filling by the manufacturer, from the state of a first opening.

[0006] The tamper-evident arrangement comprises at least one movable indicator element which, in its original state, is held detachably in an original position by means of a breakable bridge and, by interaction with a stop element on the spout, in particular on the spout nozzle, can be separated from the bridge and moved out of the original position.

[0007] Such an interaction between the at least one indicator element and a respective stop element associated with it is usually generated by an opening rotary movement, in which the indicator element comes into contact with the stop element and is moved out of the original position during further rotation of the closure cap, which can then be visually perceived by a user as an open state and distinguished from the original state.

[0008] Pouring devices of this type are generally known, e.g. from publication DE 10 2013 004 466 A1, and are used, for example, in containers designed as foil bags, e.g. for holding pasty or liquid foods.

[0009] For connection with a foil bag, a fastening part, in particular a boat-shaped fastening part, can be provided at the end of the spout facing away from the dispensing opening of the pouring spout, which is attached between two layers of foil of the foil bag, e.g. by welding / heat sealing or similar known measures.

[0010] A pouring device according to the preamble of claim 1 is known from US8528757B2.

[0011] The invention preferably relates to pouring devices with a mounting area on the spout suitable for attachment to a foil bag, but is not limited to this embodiment. The invention also relates to spouts that are already attached to a container of any kind.

[0012] In the aforementioned prior art, it is customary for a display element to be pivoted about an axis parallel to the axis of rotation when the display element is moved from its original position. In doing so, the free end of the display element is moved radially inwards.

[0013] Such a position is problematic because it makes the free end of the display element freely accessible, e.g. to children who could tear off and swallow the display element with their fingers or teeth.

[0014] The aforementioned state of the art therefore provides for the display element to be folded over by almost 180 degrees and held in place behind a projection. However, even in this case, it cannot be ruled out that – for example, during reclosing – the display element may be released from its fixed position and subsequently protrude freely radially inwards. This can occur because the stop element and the display element also move past each other during the closing movement. Thus, the aforementioned risks arise again if the device is opened again.

[0015] Folding the display element 180 degrees, possibly several times, is also problematic because this puts a lot of stress on the material in the joint area and can cause it to break quickly.

[0016] Against this background, it is an object of the invention to provide a pouring device of the type mentioned above in which access to a display element moved from its original position is made more difficult. Preferably, it is also a further object to ensure that the display element remains in its previously assumed position during a closing rotary movement.

[0017] This problem is solved by mounting the at least one display element in the originality arrangement so that it is displaceable around the axis of rotation, particularly at least in a partial area, especially after prior separation from the bridge, during interaction between the display element and the stop element. With this type of movement, the display element is thus not displaced, or at least not significantly displaced, in its radial position, and in particular is not pivoted about an axis parallel to the axis of rotation. It therefore preferably does not enter a radially inward-pointing position, as in the prior art. According to the invention, the movement of the display element takes place at least substantially in the circumferential direction around the axis of rotation, or at least partially at least substantially perpendicular to the radius vector pointing towards the axis of rotation.

[0018] Where directional terms such as "top" and "bottom" or "above" and "below" are used in the following description, they refer to a typical operating position of a pouring device on a container, i.e., the pouring device is located at the top of the container, which is assumed to be upright. The directions "axial," "radial," and "circumferential" refer to the axis of rotation around which the cap can be rotated.

[0019] Preferably the movement is such that the display element is displaceable at least partially within a plane, or within an axial area around a plane that is perpendicular to the axis of rotation / to the spout, in particular wherein the axial area is smaller than the axial height of the display element.

[0020] In the movement according to the invention, the display element preferably changes its circumferential angular position about the axis of rotation. The radial position of the display element, i.e., its distance to the axis of rotation or to the cap wall, is preferably not changed during the movement or is changed only within an insignificant radial range, in particular within a range that is smaller than the radial width of the display element, and more preferably smaller than the radial distance of the display element from the cap wall in its original state. Thus, there is effectively no relevant radial displacement during the movement, so that the display element cannot come into contact with fingers or teeth.

[0021] InIn a preferred embodiment, the aforementioned breakable bridge, which releasably holds the indicator element, projects radially outwards from the outer surface of the cap wall. This securely holds the indicator element in its original position. The bridge may be designed as a projection that tapers with increasing distance from the surface of the cap wall. This ensures that the bridge breaks close to the indicator element. The bridge defines the radial distance between the outer surface of the cap wall and the indicator element in its original position.

[0022] A particularly preferred embodiment provides that the tamper-evident device comprises at least one cover wall, preferably a cylindrical cover wall, extending axially away from the edge of the cap, particularly at least partially. This cover wall thus extends downwards from the cap, at least partially, and in particular away from the lid element of the cap or towards the container to which the pouring device is or will be attached.

[0023] The cover wall extends circumferentially around the axis of rotation and is connected to the cap wall by means of at least one connecting web projecting radially outwards in the area of ​​the cap edge on the cap wall, in particular in one piece, wherein the indicator element is arranged radially inside the cover wall.

[0024] The cover wall can, for example, be formed by a ring wall extending a full 360 degrees around the axis of rotation. Alternatively, the cover wall can be formed by at least two ring segments, each extending partially around the axis of rotation. The cover wall thus forms an inner surface assigned to the display element and an outer surface visible to a user.

[0025] Preferably, the cover plate is higher in axial height than the axial height of the display element. This ensures that the display element is covered by the cover plate, at least when it is moved from its original position.

[0026] It is further preferred that the at least one connecting web is attached to the cap wall at an axial distance from the cap edge or the end face of the cap wall in the direction of the cover element. This axial spacing from the cap edge or the end face of the cap wall ensures that the cover wall overlaps the cap wall in an axial area, particularly near the cap edge. The cover wall is thus partially overlapping the cap wall above (in the direction of the cover element) the cap edge and partially extending away from the cap wall and below the cap edge without overlap, particularly in the direction of the flange surface with the at least one stop element or towards the container. This creates an annular space between the cover wall and the cap wall under the at least one connecting web, in which the indicator element is guided in a radial direction.In this case, the radial displacement of the display element from its original position is limited by the radial width of the annular space on both sides of the display element. Preferably, the annular space has a radial width that is greater than the radial width of the display element but less than 150% of the radial width of the display element.

[0027] Preferably, the cover plate has a radial opening at the location of the original position of the display element. Through such an opening, the display element is visible to a user in its original position. The invention can then provide that the display element can be at least partially slid behind the cover plate out of view. Viewed from the radial outside, the display element can thus be moved at least partially out of the radial projection of the opening. The user can then infer the status of the dispensing device from the relative positioning of the display element to the opening.

[0028] A breakthrough can be formed, for example, by an opening in a 360-degree ring wall or by a space between two ring segments.

[0029] A further preferred embodiment provides that a radially inwardly projecting retaining element is arranged on the cover wall in an area axially below the display element and / or below its subsequently named mounting area and / or below the subsequently named joint area.

[0030] This retaining element can be arranged, for example, in the area of ​​the free edge of the cover wall, in particular flush with the edge end face of the cover wall. The retaining element can also be arranged at an axial distance from the edge end face, i.e., offset axially from the edge end face in the direction of the indicator element.

[0031] The retaining element prevents the indicator element, in particular the indicator element detached from the bridge, from falling under the retaining element or under the edge of the cover wall after being displaced in an axial direction.

[0032] Preferably, the retaining element, viewed axially, at least partially covers the display element. For this purpose, the retaining element can project radially inwards from the inside of the cover wall by an amount greater than the radial distance of the display element from the inside of the cover wall, particularly in its original position and / or in a position shifted from it.

[0033] In a preferred embodiment, the adjustability of the display element can be achieved by mounting it slidably via a hinge area. Preferably, the display element is mounted via the hinge area on the cap wall or on a radially extended connecting web to which the aforementioned cover wall is attached.

[0034] The joint area is preferably designed to allow articulation around a joint axis that is at least substantially radial. The joint area is preferably shortenable in the circumferential direction. This allows the display element to assume a reduced distance in the circumferential direction from its mounting point in the original arrangement when moved.

[0035] Preferably, the joint area comprises a first joint arm and a second joint arm, which are pivotally connected to each other about a joint axis extending at least substantially in the radial direction. The first joint arm is attached to the cap wall or to a radially extending connecting web to which the aforementioned cover wall is attached, and the second joint arm is attached to the display element, in particular to a mounting area of ​​the display element. The mounting points of the joint arms in the direction of the cap wall / connecting web or the display element can also be pivotally designed.

[0036] The articulated connection, at least between the articulated arms, can preferably be formed by a solid-state joint or a film joint, in particular by a material-reduced joint groove. The articulated connection is thus formed by the material of the articulated arms. In particular, it can be produced by injection molding.

[0037] The articulated connection between the articulated arms, with a substantially radial axis of rotation, ensures that this joint is axially movable within the originality assembly. This allows the ends of the articulated arms extending away from the joint to move circumferentially, or at least in a direction perpendicular to the radius vector of the axis of rotation. Accordingly, the display element, which is attached to the originality assembly via the joint, is displaceable in this direction.

[0038] It is particularly preferred that, in the original position of the display element, the first and second articulated arms enclose an angle of less than 180 degrees, preferably less than 160 degrees, preferably less than 140 degrees, but particularly greater than 90 degrees, wherein the angle can be reduced by displacing the display element from its original position. The axial displacement direction of the articulated connection between the articulated arms when the display element is displaced is thereby reliably predefined, particularly in the direction of the cover element of the closure cap.

[0039] InIn a further development, particularly for the aforementioned embodiment, it may be provided that a circumferentially extending opening is provided between two connecting webs with which the cover wall is attached to the cap wall, through which the articulated arms pass at least partially in the axial direction towards the cover element, in particular with the articulated connection area. Between such openings, the respective connecting web may extend circumferentially over a flat surface, in particular forming a closed surface in each case.

[0040] The movableness of the display element can preferably be designed such that, both in its original position, which is held stably by the bridge, and even after being moved from this original position, the display element lies within the axial projection of the aforementioned opening between two connecting webs. The movement thus preferably occurs from the original position after separation from the bridge within the axial projection of the aforementioned opening.

[0041] It is preferably true for all possible embodiments of the invention, including those which may not realize the aforementioned breakthrough, that the movement of the display element according to the invention takes place in an area around the axis of rotation, or in an area extending around the axis of rotation.

[0042] A preferred embodiment provides that a locking projection is arranged on the cap wall, projecting radially outwards and axially above the joint area, particularly in the original position axially above the articulated connection point of the first and second articulated arms, and in particular that the second articulated arm can be engaged behind it. It may be provided that, viewed axially, the locking projection does not cover the first and / or second articulated arm, preferably the articulated connection point between them, or only partially covers it. In particular, partial coverage may be provided only for the second articulated arm.

[0043] The invention may provide that the first articulated arm is arranged under the projection when the display element is moved and / or can be moved past it without contact, in particular so that only the second articulated arm locks into the projection.

[0044] Preferably, the radial distance of the first articulated arm from the cap wall is greater than the radial elevation of the locking projection above the cap wall, and the radial distance of the second articulated arm from the cap wall is smaller than the radial elevation of the locking projection above the cap wall.

[0045] The locking projection can be adapted on its axial underside, which faces the joint connection of both articulated arms, to the contour of the axial upper side in the area of ​​the articulated connection of the first and second articulated arms. In particular, this can simplify manufacturing by injection molding.

[0046] Furthermore, it is preferred if the detent projection has a ramp onto which the second articulated arm can run, particularly when the indicator element is moved. In this way, the ramp pushes the second articulated arm radially outwards during movement, and it then moves behind the detent projection, where it is held against backward movement.

[0047] A preferred embodiment provides that the indicator element has a mounting area for attachment to the second articulated arm and a free head area, the head area extending from the mounting area towards a flange surface surrounding the spout, on which the stop element is arranged. In the head area, the axial height of the indicator element is thus increased compared to the mounting area. This significantly limits the axial movement away from the cap. Thus, axial movement when displacing the indicator element away from the cap in an outward direction is prevented.

[0048] It is further preferred that the transition from the mounting area to the head area forms a chamfer for the stop element, particularly during a closing rotary movement. During the closing rotary movement, if the stop element on the spout and the indicator element make contact, the indicator element would be axially lifted but not moved back to its original position. The stop element thus passes under the indicator element. Therefore, the indicator element remains securely in its position after the initial opening.

[0049] The invention may, in all embodiments, preferably additionally provide that the display element and / or the joint area is at least partially radially wider than axially tall. This generally results in folding movements of the display element and / or the joint area about radial axes being preferable to folding movements about axes parallel to the axis of rotation.

[0050] The invention can provide that a handle is arranged radially outside the closure cap by means of radially extended struts, in particular wherein the tamper-evident device is arranged axially at least partially below the lower edge of the handle. In this way, the closure cap is essentially swallow-proof for children or, in the event of ingestion, allows the child to breathe through it.

[0051] In all possible configurations, the number of display elements in the originality arrangement is fundamentally arbitrary. For example, only one display element may be provided. Preferably, at least two, and in particular exactly two, display elements are provided. The preceding descriptions apply to each display element and to all related elements.

[0052] An exemplary embodiment is described with reference to the following figures. All figures show at least essentially the same embodiment from different perspectives.

[0053] The Figure 1 Figure 1 shows a perspective overview of a pouring device according to the invention. This device comprises a spout 1 with a mounting area 1a for foil bags below a pouring spout covered by the closure cap 2. A handle 3 is arranged radially around the closure cap via ribs.

[0054] The originality arrangement comprises a display element 4, which is visible through an opening 6a in a cover wall 6 extending in a ring shape around the axis of rotation 5. Figure 1 Display element 4 is shown in its original position, representing a state originally sealed by the manufacturer.

[0055] The Figure 2Figure 1 shows only the spout 1 of the pouring device with lower mounting area 1a and the hollow pouring nozzle 1b adjoining it upwards, which has, for example, an external thread on its outer surface for interaction with a corresponding internal thread on the inner surface of the cap wall of the closure cap 2. On a flange surface 7, which is formed around the pouring nozzle and lies in a plane perpendicular to the axis of rotation 5, a number of stop elements 8 corresponding to the number of indicator elements are arranged, each of which interacts with an indicator element 4.

[0056] Each stop element 8 can, in any version, project radially outwards from the pouring spout and axially upwards from the flange surface 7 towards the dispensing opening 9, regardless of the one shown here.

[0057] When the closure cap 2 is rotated, the indicator element 4 comes into contact with the stop element 8 from its originality arrangement and is thereby moved.

[0058] The Figure 3 Figure 1 shows only the closure cap 2 with the handle 3 arranged around it. Two connecting webs 10 are provided at the lower edge of the cap 2b, axially offset from the end face of the cap 2b in the direction of the cap lid 2c (not shown here). These webs extend radially outwards from the cap wall 2a and also partially around the cap wall 2a in the circumferential direction. At the radial end of the connecting webs 10, the already mentioned Figure 1The cover plate 6 shown, which extends circumferentially around the axis of rotation 5, is held in place. The cover plate 6 has a radial opening 6a for each of the two display elements 4. Through these openings 6a, a user can see the display elements 4, which are located radially inside the cover plate 6, in their original position.

[0059] The Figure 4 Figure 1 shows a cutaway view of the display element 4 and its mounting in the original arrangement in relation to the closure cap 2. The cap wall 2a shown here is closed at the top by the cover element 2c. It is also evident that there is a circumferentially extending opening 10a between two connecting webs 10, through which the articulated arms 12a and 12b can pass axially towards the cover element 2c, at least partially, in particular with their articulated connection area.

[0060] The Figure 5Figure 1 shows the display element 4 and its surroundings in greater detail. The display element 4 is movably attached to the connecting web 10 by means of an articulated section consisting of a first articulated arm 12a and a second articulated arm 12b. The two articulated arms 12a and 12b are articulated to each other by means of an articulated groove 12c, which represents a local reduction in material. The other end of the first articulated arm 12a is also articulated to the connecting web 10, and the other end of the second articulated arm 12b is also articulated to the display element 4. The articulated arms 12a and 12b form an angle between them greater than 90 degrees and less than 180 degrees. By moving the display element 4 circumferentially, the articulated groove 12c is moved axially upwards, and the angle between the articulated arms 12a and 12b is reduced.In this process, the second articulated arm 12b, viewed circumferentially, moves behind the locking projection 13. To facilitate this, it has a ramp 13a.

[0061] The articulated arm 12b, which has a smaller radial distance to the outer surface of the cap wall 2a than the articulated arm 12a, is initially pushed radially away from the cap wall 2a by the ramp until it can retract radially and engage behind the detent projection 13. The detent projection 13 preferably extends radially further from the cap wall 2a than the breakable bridge 11, with which the indicator element 4 is detachably attached to the cap wall 2a in its original position.

[0062] The Figure 6Figure 1 shows the same arrangement in a bottom view. Here it is also evident that the indicator element 4 has a free head area 4a that extends downwards from a mounting area 4b. The transition between the mounting area 4b and the head area 4a is via the chamfer 4c, by means of which the head area 4a can be pushed upwards when the stop element 8 moves past the head area 4a during a closing rotation.

[0063] This view also shows that an annular space is formed between the cover wall 6 and the cap wall 2a at the lower edge of the cap 2b, in which the indicator element 4 is held radially.

[0064] The Figure 6a shows in relation to the Figure 6A possible further development in which the display element 4 is also held in a downward axial direction. For this purpose, particularly in the original position and / or in the position shifted from it, a retaining element 6b projecting radially inwards from the cover wall 6 is provided on the cover wall 6 below the display element 4, especially below its mounting area 4b to which the second articulated arm 12b is attached, and preferably also below the second articulated arm 12b. This retaining element 6b at least partially covers the display element 4 in the axial direction, particularly when it has been shifted from its original position about the axis of rotation 5 after being detached from the bridge 11. Thus, after being detached from the bridge 11, the display element 4 cannot move in the axial direction below the retaining element 6b, and in particular, it cannot move below the free edge of the cover wall 6.Even with the cap removed from the container, this reliably prevents the indicator element 4 from being accessible to children's fingers or teeth. Figure 7 The entire pouring device is shown in an open state, in which the display element has been moved out of the field of vision of the opening 6a and behind the cover wall 6, thus visualizing the open state to the user.

[0065] The Figure 8 The cutaway view shows the displaced display element 4, with the articulated arms 12a and 12b forming a smaller angle to each other compared to the original position. It is clearly visible that the articulated arm 12b is locked behind the detent projection 13, thus securely holding the display element 4 in this position.
