Description

Title of the invention: Closure unit intended to be connected to a flask or a cup, in particular an insulated cup FIELD OF THE INVENTION

[0001] The invention relates to a closure unit intended to be connected to a flask or a cup, in particular an insulated cup. STATE OF THE ART

[0002] DE 20 2017 100 771 U1 discloses a bottle cap for an insulating container for hot drinks. DE102019128302B3 describes a bottle cap for a bottle with a narrow bottle neck. Both solutions have in common that they offer a high level of tightness because they provide two independent sealing planes. This not only ensures high safety against leakage when the container is tilted, but also provides high tightness in the case of carbonated drinks resulting in high internal container pressure. Leakage of residual quantities of liquid after closing the cap is also prevented. The major disadvantage of sophisticated bottle caps is that handling with two hands is necessary and / or a high force is required to press the actuation button.The actuating button for opening or closing the bottle cap must always be actuated directly against the spring force of a spring, whereby the spring force must be sufficiently high so that there is a sufficiently high application pressure of the sealing elements against their contact surfaces and the sealing effect is maintained in all operating positions. Therefore, one-handed operation is only possible for persons who hold the bottle by the bottle cap and can also press the actuating button at the same time. Statement of the invention

[0003] The objective of the invention is therefore to provide a closure unit intended to be connected to a flask or a cup, which allows easy handling with one hand.

[0004] As is customary for known closure units for insulated bottles, insulated cups and drinking bottles for the mobile transport of beverages, a spout element is provided with a spout edge which surrounds at least one pouring opening, the pouring opening being closable via a sealing element.

[0005] In the case of the closure element according to the invention, however, the spout element is not directly connected to the drinking bottle or cup; rather, a complementary base element is provided, which is arranged between the drinking bottle or cup and is to be fixedly connected thereto. The spout element is mounted and movably guided in the base element so that it can be slid along the central axis of the closure unit or parallel thereto and can thus be lifted from the base element. At least one spring element is provided for lifting the spout element from the base element.

[0006] According to the invention, single-handed operation of the closure unit is facilitated by the fact that a pivoting cover is provided which counteracts the high spring force, which is also required for the closure unit according to the invention in order to ensure sealing. In doing so, however, it is convenient to use one or more fingers at the upper side of the cover to carry out the pivoting, which is easier than pressing a central actuating button axially downwards, especially when holding the closure unit with the same hand at the same time.

[0007] During the opening movement, the cover slides over the edge of the elastically mounted spout element. In doing so, only the sliding friction force has to be overcome. During the closing movement, the cover slides again over the edge of the elastically mounted spout element. In doing so, in addition to overcoming the sliding friction force, the spring element also has to be pre-tensioned. Since the pivotally mounted cover is pivoted through a large radius and the increasing spring tension during closing is held in each intermediate position by the cover fixedly mounted against the base element, the closing movement with one hand can also be carried out with less force compared to a known closing unit with a central actuating button.

[0008] The sealing of the pouring opening is achieved by pushing the movable spout element onto the base element and thereby pushing at least one sealing element present at the spout element or the base element onto at least one pouring opening against the respective other element. If the spout element is raised again by the spring force, the seal is then released.

[0009] In doing so, the sealing element can be fixedly arranged in the base element, so that in the event that a pouring spout element is lowered onto the base element, the pouring opening of the pouring spout element is closed.

[0010] Alternatively, the sealing element may be fixedly arranged in the spout element, so that in the event that a spout element is lowered onto the base element, the discharge opening is closed against the base element.

[0011] The user must apply the spout element against the base element by the by closing the cover against the force of the spring element inserted between the two. In doing so, the spring element is pre-tensioned, so that the spout element is automatically lifted from the base element when the cover is later pivoted apart and no further force is exerted.

[0012] For this reason, a locking device is also provided to hold the spout element in the lowered position relative to the base element and against the force of the pre-stressed spring element. Preferably, the locking device is formed with the cover, with which the upwardly open area of ​​the spout element can at the same time be covered and thereby protected against soiling.

[0013] A particularly advantageous design of the invention provides a spring element which is designed in the form of a pipe section and is made of an elastomeric plastic material, in particular silicone. In doing so, several advantages can thus be simultaneously achieved: - The silicone spring element stores sufficient spring energy in the compressed state to be able to lift the spout element from the base element again at a later date, even if beverage residues cause occasional sticking. - It is food safe and can come into direct contact with drinking liquid.

[0014] In particular, this type of spring element, which is placed between the base element and the spout element, also makes it possible to design a sealing tunnel which surrounds the sealing element, the pouring opening of the base element and the pouring opening of the spout element. The spring element connects with its ends to the underside of the spout element and to the upper side of the base element, so that a space completely closed to the outside is formed inside the closure element as soon as the sealing element bears against the pouring opening.

[0015] It is also possible to manufacture the sealing element provided for closing the pouring opening and an elastomer spring element in one piece, in that for example an outer wall is provided which stores the spring force when the spout and base elements approach each other, and a central sealing element for closing the pouring opening which is connected to the outer wall via radial spokes.

[0016] It is also conceivable to provide only a central sealing element for closing the discharge opening, which is compressible in itself and in doing so can at the same time act as a spring element.

[0017] In a first embodiment, the cover comprises only a lid element which is connected to the base element via pivot pins. It can be pivoted aside, whereby an extension of the spring element occurs and the pouring spout element is lifted, whereby the pouring opening is released in turn.

[0018] To enable pivoting, the contours of the upper edges at the base member and the spout member are adapted to the pivoting path falling from top to bottom, and fall toward the side toward which the lid member pivots.

[0019] Alternatively, the cover may comprise a bracket which is pivotally mounted against the base element, and a cover element which in turn is movably mounted against the bracket. In order to hold the cover element on the upper side of the closure unit and to prevent unintentional pivoting of the bracket, the cover element may have on its underside an actuating button with at least one cam, which is fixed by positive engagement against the inner edge of the spout edge in a closed position of the closure unit.

[0020] It is also advantageous to guide the movement of the spout element in the base element. For this purpose, at least one inlet nozzle is provided, which surrounds the pouring opening of the spout element and connects to the underside of the spout element. It further extends through the sealing tunnel, if present, and through the at least one pouring opening of the base element into the area of ​​the neck of the drinking bottle or cup.

[0021] It is in particular provided that the inlet pipe is formed from several segments, each of which extends through a partial area of ​​the discharge opening of the base element.

[0022] It is also advantageous to provide, at least between one of the segments and the base element, a form-fitting fastening that can be removed, by which the sliding stroke of the spout element is limited. This can be achieved in that at least one segment is elastically connected to the spout element and in that at least one projection is formed against the segment, which engages form-fittingly in a recess or under a recess at the base element.

[0023] It may further be provided that the inlet pipe has against its inner wall and in several positions, at least in at least two diametrically opposite, respectively a pair of ribs between which a fluid-conducting chamber is designed, the ribs extending radially inwards to the outer periphery of the sealing element, so that a chamber open towards the centre is respectively designed. In this way, when drinking, the liquid can be conducted through one chamber and the air through another chamber, whereby the liquid flows out evenly and a jerky liquid outlet is avoided.

[0024] In the case of a cup with a larger cross-sectional area and covered by the base element, it is advantageous to design a ventilation nozzle with a ventilation opening away from the pouring opening and to fix a ventilation closing element at the underside of the spout element. The ventilation opening in the base element is automatically closed when the spout element is lowered onto the base element.

[0025] Thus, the present disclosure relates to a closure unit for connection to a drinking bottle or a cup, in particular an insulated cup, with at least one pouring spout element with a pouring spout edge which surrounds at least one pouring opening, in which the pouring opening can be closed via a sealing element,

[0026] in which: - a base element separate from the spout element is provided with at least one pouring opening to be fixedly connected to the drinking bottle or cup; - the spout element is guided in a vertically movable manner in or against the base element, wherein the spout element can be lifted from the base element via a spring element; - the sealing element closes at least one of the pouring openings in the event that the spout element is lowered onto the base element; and - a stopping device is provided, with which the spout element can be stopped in the lowered position relative to the base element and against the force of the spring element.

[0027] According to one embodiment, the sealing element is fixedly arranged in the base element and, in the case where the spout element is lowered onto the base element, the pouring opening is closed against the spout element.

[0060] [Fig.l] shows, in a perspective view, a closable insulated cup, composed of a cup-shaped insulated beverage container 200 and a unit closure unit 100 screwed thereon. The closure unit 100 comprises a base element 20 which is directly connected to the beverage container 200 and a pivotable cover 30 which is pivotally connected to the base element 20 via pivot pins 31.

[0061] [Fig. 2] shows, in another perspective view, the beverage container composed of the beverage container 200 and the closure unit 100. The cover 30 is pivoted downwards about the pivot axes 31.

[0062] Due to the pivoting of the cover 30, a spout element 10 resiliently mounted inside the base element 20 is no longer held by form cooperation, so that it has been propelled vertically upwards due to the force of a spring acting between the base element 20 and the spout element 10.

[0063] As can also be seen in [Fig. 2], a particular contour of a spout edge 12 is provided against the spout element 10. In the side facing away from the cover 30, the spout edge 12 unfolds with its upper edge in a horizontal plane relative to which the central axis unfolds as a normal. Conversely, the upper edge of the spout edge 12 falls on the side facing the cover 30 and in doing so follows the pivoting path of the cover 30. This allows the cover 30 to slide over the spout edge 12 upon subsequent closing and in doing so to press the spout element 10 deeper into the base element 20 again against the force of the inner spring element.

[0064] When the cover 30 is in the closed position shown in the figure, the elastically mounted spout element 10 is thereby also held in its lowered position. The cover 30 therefore constitutes a stopping device.

[0065] [Fig. 3] is an exploded perspective view of the beverage container 200 with the closure unit 100. In the upper area, the spout element 10 with its spout edge 12 can be seen. It has a downwardly projecting inlet nozzle 11. The base element 20 has a rib 22 with an upper edge whose contour runs analogously to the contour of the upper edge of the spout edge 12 against the spout element 10, so that the two together form a single edge when the spout element 10 is lowered into the base element 20.

[0066] The base element 20 has bearings 21 for the pivot axes of the cover 30. A bottle neck seal 55 is inserted between the neck 210 of the beverage container 200 and the base element 20 to seal the connection between them.

[0067] A mushroom-shaped sealing element 51 is fixedly positioned in the base element 20 and serves to seal a discharge opening in the spout element 10. The sealing element 51 is made of an elastomeric material.

[0068] Furthermore, a spring element 52 is provided, which also consists of an elastomeric material, in particular silicone, and which has the shape of a short pipe section. Inside the spring element 52, a tunnel is actually designed through which the inlet nozzle 11 of the base element is guided. Furthermore, the spring element 52 can be compressed axially in the direction of its central axis, so that an elastic deformation occurs which allows the spout element 10 to be lifted vertically relative to the base element 20 as soon as the cover 30 has been laterally pivoted apart.

[0069] Another elastomeric component is a vent closure element 16 which is secured at the underside of the spout element 10 and which closes a vent opening, not visible here, in the base element 20 when the spout element 10 is lowered onto the base element 20.

[0070] [Fig.4] shows the parts before assembly in a cross-sectional representation in perspective. The base element 20 has a broadly cylindrical outer contour with an upwardly rising cylindrical rib 22 and a cover area 23 inserted approximately halfway up and closing the cross-section inside the rib 22. By its inner diameter, the rib 22 rising upwards above the cover area 23 matches the outer diameter of the spout element 10.

[0071] In the cover region 23 a sealing element holder 24 is formed in which the sealing element 51 is held. The sealing element holder 24 has transversely extending spokes or support bridge for holding the sealing element 51 in the center, the spokes or support bridge extending beyond a pouring opening without completely closing it.

[0072] In the lower area, the base element 20 has a threaded section 29 with an internal thread over which it is screwed onto the neck section 201 of the beverage container 200. In doing so, the neck seal 55 is compressed between the base element 20 and the upper edge of the neck section 201 and seals the connection.

[0073] At the base element 20, the spring element 52 is recognizable, which forms in its interior a sealing tunnel 53 through which the inlet nozzle 11 extends. At the upper end of the inlet nozzle 11 there is a discharge chamber 14 whose cross-section is larger than the cross-section of a pouring opening 15. The spout element 10 also has, in addition to the circumferential spout edge 12, a cover region 13 which covers the cross-section inside the spout edge 12. At the underside of the cover region 13 a receptacle for the closure element is provided ventilation 16. This presses from above on a ventilation pipe 26 against the base element with a ventilation opening located inside.

[0074] [Fig. 5] also shows in a perspective sectional view the closed, fully assembled beverage container with the closure unit. The closure unit 100 is screwed onto the beverage container 200. The spout element 10 is in a lowered position relative to the base element 20. In doing so, the spring element 52 is compressed and the ventilation closure element 16 rests on the ventilation nozzle 26. With its mushroom-shaped head 51.1 against the upper side, the sealing element 51 presses against the spout element 10 into the pouring chamber 14.

[0075] The covering 30 completes the outer contour of the closure unit 100 predefined by the rib 22 and covers at the upper side the open area of ​​the pouring spout element 10.

[0076] The inlet tubing 11 consists of several segments which extend through the pouring openings in the lid area of ​​the base element 20 into the beverage container 200.

[0077] [Fig. 6] shows the opening process of the closure unit 100. A user exerts a force perpendicular to the central axis on the cover 30 with the thumb 1, so that it lifts from the upper edge of the rib 22 and the spout edge 12. The cover 30 performs a pivoting movement to the side due to its connection with the base element 20 against the pivot bearing. With the pivoting separation of the cover, the spout element 10 is no longer fixed against the base element 20 and is propelled upwards by the spring energy stored in the spring element 52 during the previous compression, as soon as the spring element 52 can relax again.When the spout element 10 is slid upwards, the contact of the mushroom-shaped head of the sealing element 51 with the pouring chamber 14 is also removed, so that the pouring opening 15 is released. At the same time, the vent closure element 16 lifts from the vent pipe 26.

[0078] [Fig. 7] shows a perspective sectional representation through the open closure unit 100 with the beverage container 200. The spring element 52 is completely relaxed, and the spout element 10 is raised to the maximum height relative to the base element 20. The lines with arrows in the left-hand area indicate the flow from the beverage container 200 into the inlet nozzle 11. The flow takes place through pouring openings which are located all around the sealing element 51 in the lid area 23 of the base element 20 and finally through the pouring chamber 14 and the opening of spill 15 in the upper area delimited by the spill edge 12 against the spout element 10.

[0079] [Fig. 8] shows how the base element 20 and the spout element 10 can be separated from each other for cleaning purposes. For this purpose, the inlet nozzle 11 consisting of several segments is compressed radially, whereby a form-fitting fixation of the inlet nozzle 11 in the base element 20 is eliminated, so that the spout element 10 can be removed upwards.

[0080] The cover 30 is designed so that in its lowered position it does not prevent the removal of the spout element 10 from the base element 20.

[0081] [Fig. 9] shows another embodiment of a closure unit 100' which is designed for a thin drinking bottle 200', in a perspective view. The closure unit 100' comprises a base element 20', which is directly connected to the drinking bottle 200', and a cover 30'. The cover 30' has a bracket 33', which is pivotally connected to the base element 20' via pivot pins 31', and a lid element 32' which in turn is hingedly connected to the bracket 33'. A release button 34' is integrated in the lid element 32'.

[0082] [Fig. 10] shows, in another perspective view, the combination of the drinking bottle 200' and the closure unit 100' in the open position. The bracket 33' has been pivoted downwards about the pivot axes 31', whereby the lid element 32' has been moved away from the upper side of the base element 20'. In doing so, a spout element 10' resiliently mounted inside the base element 20' is no longer held by positive engagement, so that it has been propelled vertically upwards due to the force of a spring acting between the base element 20' and the spout element 10'. The area surrounded by a spout edge 12' is now free. A pouring opening 15' is freed there. A 51' sealing element can be seen there.

[0083] [Fig. 11] shows parts of the alternative closure unit 100' for the slim 200' drinking bottle. The closure unit 100' comprises a base element 20' and a cover 30' which is pivotally attached thereto against a bearing axis 31'. The closure unit 100' also has a spout element, which is not shown here.

[0084] In the lower region of the base element 20' a threaded section 29' is designed for connection to the thin bottle neck 201 of the bottle. The base element 20' tapers for this purpose from a threaded section 29' upwards to a discharge opening 25'. A support bridge 27' holds a sealing element holder 24' for fixing the sealing element 51' in the center of a discharge opening 25'. The sealing element 51' has at the upper side a mushroom-shaped head 51.1' and at the lower side of its shaft a collar 51.2' enlarged in circumference.

[0085] In the shown example of the closure unit 100', a lid area 23' between a pouring spout edge 22' and the pouring opening 25' is designed very thin and tapers into a trough, which serves to accommodate a cylindrical spring element 52.

[0086] [Fig. 12] shows the closure unit 100' fully assembled in the closed position. In the lower area, an upper section of the bottle 200' with the bottle neck 201' can be seen. The base element 20' is screwed with its threaded section 29' onto the bottle neck 201'. A bottle neck seal 55' inserted between these ensures the seal between the two elements.

[0087] In the upper region of the closure unit 100', a cover 30' is placed and covers the region of the spout element 10' surrounded by the spout edge 12'. The cover element 32' of the cover 30' is mounted against the bracket 33', which in turn is pivotally mounted against the base element 20', as already described above with reference to [Fig.l].

[0088] The cover 30' has an actuating button 34' which has a cam 35' at the lower side. This bears against the inner edge of the spout edge 12' and is thus fixed by positive engagement. In the position shown, pivoting of the bracket 33' is not possible because the cover element 32' bears on the upper edge of the rib 22' in a pivoting direction to the left, and in the opposite direction the cam 35' bears against the spout edge 12'.

[0089] The sealing element 51 is inserted into the sealing element holder 24'. A pouring spout element 10' is inserted into the space inside the rib 22' of the base element 20'. This surrounds with the pouring spout edge 12' an upwardly open space, at the lower side of which there is a discharge opening which in the position shown in [Fig. 10] is closed by the mushroom-shaped head 51.1 of the sealing element 51.

[0090] Between the base element 20' and the spout element 10' is inserted an elastomer spring element 52 made of silicone which is formed in the manner of a pipe section. Inside, it forms a sealing tunnel 53 which surrounds the area of ​​the pouring opening in the base element 20' and the inlet nozzle 11' of the spout element 10 and thereby makes the entire intermediate space between the base element 20' and the spout element 10' liquid-tight. For this purpose, both the upper edge area and the lower edge area of ​​the spring element 52 are pressed in a sealing manner into annular grooves in the base element 20' or in the spout element 10'.

[0091] The inlet tubing 11' extends through the areas of a spill opening in the base member 20' which are not locked by the support bridge 27' for the sealing member 51. To bypass the support bridge 27', the inlet tubing 11' is divided into several segments, one or more of which extend respectively through a section of the spill opening.

[0092] [Fig. 17] shows the base element 20' from the lower side. The spill opening 25' is divided into two parts by the support bridge 27' and the sealing element support 24'.

[0093] [Fig. 16] shows the spout element 10' seen from below. In the center of the base element 10' is the pouring opening 15'. In this case, the inlet nozzle 11' consists of two segments 11.2', 11.3', between which there is a gap on either side, in which the support bridge of the base element can be accommodated. If the segment 11.2' is rigidly connected to the base element 10', the other segment 11.3' is, on the other hand, elastically brought against the base element, so that it can be pushed inwards, towards the center. Ribs 11.1' on the inner side of the segments 11.2', 11.3' extend radially somewhat inwardly until the mushroom-shaped head of the sealing element can be positioned centrally. A chamber 11.4' is provided between each pair of ribs 11.1'. This allows liquid or air to pass past the mushroom-shaped head.The fact that several 11.4' chambers are designed around the circumference, in particular in at least two diametrically opposite positions, makes it possible to guide an outgoing liquid and the subsequently inflowing air into separate flow paths. In the case of the 100' closure unit, the typical gurgling noise that occurs when drinking from drinking bottles with a narrow bottle neck is avoided.

[0094] [Fig. 13] shows the start of the opening of the closing unit 100'. This is triggered by pushing the button 34' downwards. In doing so, the cam 35' is disengaged from the spout edge 12' and the stop equipment formed by the cover is thus unlocked. The bracket 33' can now be pivoted in the direction indicated by the arrow.

[0095] In [Fig. 14], the closing unit 100' can be seen completely open. The bracket 33' has been pivoted downwards as far as possible, whereby the cover element 32' has at the same time been brought into a lateral position against the base element 20'. The spring element 52 can relax due to the pivoting of the cover, whereby the spout element 10' is slid vertically upwards, so that a larger gap is created between the spout element 10' and the base element 20'. The central sealing element 51' with its head in the shape of mushroom 51.1' is moved away from the pouring opening 15' by the movement of the pouring spout element 10' and releases it.

[0096] Inside the spring element 52' is formed a sealing tunnel 53' which completely seals the area which is delimited upwards and downwards by the base element 20' and the spout element 10'. The inlet pipe 11' is passed through the sealing tunnel 53.

[0097] [Fig. 15] shows how the spout element 10' can be removed vertically upwards. The segments 11.2', 11.3' of the inlet pipe are pushed against each other. A projection 11.5' is formed against the segment 11.3', which engages under the cover section 23'. As soon as the projection 11.5' is extended, the form-fitting connection is released and the spout element 10' can be removed from the base element 20'.

[0098] In the representation in [Fig. 18], the spout element 10' is removed from the base element 20', including the silicone hose which serves as the spring element 52' and forms the sealing tunnel. Reference signs#:
