Description

Title of the invention: A closure unit intended to be connected to a water bottle or cup, in particular an insulated cup. SCOPE OF THE INVENTION

[0001] The invention relates to a closure unit intended to be connected to a water bottle 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 insulated container for hot beverages. DE102019128302B3 describes a bottle cap for a bottle with a narrow neck. Both solutions offer a high level of sealing because they incorporate two independent sealing surfaces. This ensures not only a high level of leakage protection when the container is tipped over, but also a high level of sealing in the case of carbonated beverages, which result in high internal pressure within the container. Leaking of residual liquid after the cap is closed is also prevented. The major drawback of sophisticated bottle caps is that they require two-handed operation and / or significant force to press the release button.The button for opening or closing the bottle cap must always be operated directly against the spring force of a spring. This spring force must be sufficient to apply adequate pressure to the sealing elements against their contact surfaces, maintaining a tight seal in all positions. Therefore, one-handed operation is only possible for those who can hold the bottle by the cap and simultaneously press the button. Description of the invention

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

[0004] As is usually the case for closure units known for insulated bottles, insulated cups and water 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 able to be closed via a sealing element.

[0005] In the case of the closure element according to the invention, the spout element is not directly connected to the bottle or cup; rather, a complementary base element is provided, which is arranged between the bottle or cup and must be fixedly connected to it. The spout element is mounted and movably guided within the base element so that it can be slid along the central axis of the closure unit or parallel to it 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, one-handed operation of the locking unit is facilitated by the presence of a pivoting cover that counteracts the high spring force, which is also necessary for the locking unit according to the invention to ensure a seal. However, it is also possible to conveniently use one or more fingers on the upper side of the cover to perform the pivoting action, which is easier than axially pushing down on a central actuation button, particularly when simultaneously holding the locking unit with the same hand.

[0007] During the opening movement, the cover slides along the edge of the elastically mounted spout element. In doing so, only the sliding friction force needs to be overcome. During the closing movement, the cover again slides along the edge of the elastically mounted spout element. In doing so, in addition to overcoming the sliding friction force, the spring element must also be preloaded. Since the pivotally mounted cover is pivoted through a large radius and the increasing spring tension during closing is maintained at each intermediate position by the fixedly mounted cover against the base element, the one-handed closing movement can also be achieved 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, thereby pushing at least one sealing element present on the spout element or the base element onto at least one pouring opening against the other respective element. If the spout element is then raised again by the spring force, the seal is broken.

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

[0010] According to another possibility, the sealing element can be fixedly arranged in the spout element, so that in the case where a spout element is lowered down to 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 bias of the closing of the cover against the force of the spring element inserted between the two. In doing so, the spring element is pre-stressed, so that the spout element is automatically lifted from the base element when later the cover is opened by pivoting and no further force is exerted.

[0012] This is why a stop device is also provided to hold the spout element in the lowered position relative to the base element and against the force of the preloaded spring element. Preferably, the stop device is formed with the cover, which simultaneously covers the upward-opening area of ​​the spout element and thereby protects it from soiling.

[0013] A particularly advantageous design of the invention provides for a spring element that is designed in the form of a pipe section and is made of an elastomeric plastic material, in particular silicone. In so doing, several advantages can be obtained simultaneously: - The silicone spring element stores enough spring energy in the compressed state to be able to subsequently lift the spout element from the base element again, even if drink residue were to cause occasional sticking. - It is food-safe and can come into direct contact with the beverage 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 that surrounds the sealing element, the spout opening of the base element, and the spout opening of the spout element. The spring element connects with its ends to the lower side of the spout element and the upper side of the base element, so that a completely closed space is formed inside the sealing element as soon as the sealing element is pressed against the spout opening.

[0015] It is also possible to manufacture in one piece the sealing element intended for closing the pouring opening and a spring element made of elastomer, in that for example an outer wall is provided which stores the spring force when the spout and base elements come together, 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 the closure of the discharge opening, which is compressible in itself and in so doing 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 axes. It can be moved aside by pivoting it to the side, thereby extending the spring element and lifting the spout element, thereby releasing the pouring opening.

[0018] To allow pivoting, the contours of the upper edges at the level of the base element and the spout element are adapted to the pivoting trajectory falling from top to bottom, and fall towards the side towards which the lid element pivots.

[0019] According to another possibility, the cover may include a bracket that is pivotally mounted against the base element, and a lid element that is movablely mounted against the bracket. To hold the lid element on the upper side of the closure unit and prevent unintentional pivoting of the bracket, the lid element may have, on its lower side, an actuating button with at least one cam, which is fixed by form cooperation 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 within the base element. For this purpose, at least one inlet tube is provided, which surrounds the spout opening of the spout element and connects to the lower side of the spout element. It further extends through the sealing tunnel, if present, and through at least one spout opening of the base element to the neck area of ​​the bottle or cup.

[0021] In particular, the inlet tube is provided to be formed of 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-cooperative fastening that can be removed, thereby limiting the sliding stroke of the spout element. This can be achieved by having at least one segment elastically connected to the spout element and by having at least one projection formed against the segment, which engages by form cooperation in a recess or under a recess in the base element.

[0023] It may also be provided that the inlet pipe is present against its inner wall in several positions, at least in at least two diametrically opposed positions Opposite each other, a pair of ribs forms a fluid-conducting chamber between them. The ribs extend radially inward to the outer periphery of the sealing element, creating a chamber open towards the center. This design allows liquid to be conducted through one chamber and air through another when drinking, ensuring a smooth flow and preventing jerky sipping.

[0024] In the case of a cup with a larger cross-sectional area covered by the base element, it is advantageous to design a vent tube with a vent opening located away from the spout opening and to attach a vent closure element to the lower side of the spout element. The vent 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 intended to be connected to a water bottle or cup, in particular an insulated cup, with at least one spout element having a spout edge that surrounds at least one pouring opening, in which the pouring opening can be closed via a sealing element,

[0026] in which: - a separate base element from the spout element is provided with at least one pouring opening to be fixedly connected to the bottle or cup; - the spout element is guided in a vertically movable manner in or against the base element, in which 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 down 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 down onto the base element, the pouring opening is closed against the spout element.

[0028] According to one embodiment, the sealing element is fixedly arranged in the spout element and, in the case where the spout element is lowered down onto the base element, the pouring opening is closed against the base element.

[0060] [Fig. 1] shows, in a perspective view, a closed insulated cup, consisting of an insulated 200-liter cup-shaped beverage container and a unit The closure unit 100 is screwed onto it. The closure unit 100 comprises a base element 20 which is directly connected to the beverage container 200 and a pivoting cover 30 which is pivotally connected to the base element 20 via pivot axes 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 elastically mounted inside the base element 20 is no longer held by cooperation of form, so that it was 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. On the side opposite 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 so doing, follows the pivoting path of the cover 30. This allows the cover 30 to slide over the spout edge 12 during subsequent closure and, in so doing, to push the spout element 10 further into the base element 20 against the force of the internal 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 stop device.

[0065] Figure 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 an inlet tube 11 projecting downwards. The base element 20 has a rib 22 with an upper border whose contour runs analogously to the contour of the upper border 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 spillway opening in The spout element 10. The sealing element 51 consists of an elastomeric material.

[0068] In addition, a spring element 52 is provided, which is also made of an elastomeric material, in particular silicone, and which has the shape of a short section of pipe. Inside the spring element 52 is a tunnel through which the inlet tube 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 moved apart by pivoting.

[0069] Another elastomeric component is a vent closure element 16 which is fixed to the lower side 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 down onto the base element 20.

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

[0071] In the lid area 23, a support for the sealing element 24 is formed in which the sealing element 51 is held. The support for the sealing element 24 has radii or a support bridge extending transversely to hold the sealing element 51 in the center, the radii or support bridge extending beyond a discharge 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 identified, which forms within its interior a sealing tunnel 53 through which the inlet tube 11 extends. At the upper end of the inlet tube 11 is a discharge chamber 14 whose cross-section is larger than the cross-section of a discharge opening 15. The spout element 10 also has, in addition to the peripheral spout edge 12, a cover area 13 that covers the cross-section inside the spout edge 12. A housing for the closing element is provided on the lower side of the cover area 13. ventilation 16. This presses from above on a ventilation tube 26 against the base element with a ventilation opening located inside.

[0074] Figure 5 shows, also in a perspective cross-sectional view, the fully assembled, closed beverage container with the closure unit. The closure unit 100 is screwed onto the beverage container 200. The spout element 10 is in a lower position relative to the base element 20. This compresses the spring element 52 and the vent closure element 16 rests on the vent tube 26. With its mushroom-shaped head 51.1 against the upper side, the sealing element 51 presses against the spout element 10 in the pouring chamber 14.

[0075] The cover 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 spout element 10.

[0076] The inlet tube 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] Figure 6 shows the opening process of the closing unit 100. A user applies a force perpendicular to the central axis with their thumb 1 on the cover 30, causing it to lift from the upper edge of the rib 22 and the spout edge 12. The cover 30 pivots to the side due to its connection with the base element 20 against the pivot bearing. With the cover pivoting open, 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 eliminated, so that the pouring opening 15 is released. At the same time, the vent closure element 16 is lifted from the vent tube 26.

[0078] Figure 7 shows a perspective cross-sectional representation through the open closure unit 100 with the beverage container 200. The spring element 52 is fully extended, and the spout element 10 is raised to its 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 tube 11. The flow occurs through pouring openings 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 spillage 15 into the upper zone delimited by the spillage edge 12 against the spout element 10.

[0079] Figure 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 tube 11, composed of several segments, is radially compressed, thereby releasing a form-cooperative attachment of the inlet tube 11 to the base element 20, so that the spout element 10 can be lifted 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] Figure 9 shows another embodiment of a closure unit 100' designed for a slim flask 200', in a perspective view. The closure unit 100' comprises a base element 20', which is directly connected to the flask 200', and a cover 30'. The cover 30' has a bracket 33', which is pivotally connected to the base element 20' via pivot axes 31', and a lid element 32', which is articulated to the bracket 33'. A release button 34' is integrated into the lid element 32'.

[0082] Fig. 10 shows, in another perspective view, the combination of the bottle 200' and the closure unit 100' in the open position. The bracket 33' has been pivoted downwards about the pivot axes 31', thereby moving the lid element 32' away from the upper side of the base element 20'. In doing so, a spout element 10' elastically mounted inside the base element 20' is no longer held in place by shape cooperation, and is thus propelled vertically upwards by the force of a spring acting between the base element 20' and the spout element 10'. The area enclosed by a spout edge 12' is now free. A pouring opening 15' is thus exposed. We can see a 51' sealing element there.

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

[0084] In the lower area of ​​the base element 20', a threaded section 29' is provided for connection with the narrow neck of the flask 201. The base element 20' tapers upwards from this threaded section 29' to a discharge opening 25'. A support bridge 27' holds a sealing element support 24' for attaching the sealing element 51' to the center of a discharge opening 25'. The sealing element 51' has, on its upper side, a mushroom-shaped head 51.1' and at the lower side of its tree a collar 51.2' widened in circumference.

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

[0086] Figure 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 gasket 55' inserted between them ensures a seal between the two elements.

[0087] In the upper area of ​​the closing unit 100', a cover 30' is placed and covers the area of ​​the spout element 10' surrounded by the spout edge 12'. The lid element 32' of the cover 30' is mounted against the bracket 33', the latter being in turn pivotally mounted against the base element 20', as already described previously with reference to [Fig.1].

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

[0089] The sealing element 51 is inserted into the sealing element support 24'. A spout element 10' is inserted into the space inside the rib 22' of the base element 20'. This surrounds, with the spout edge 12', an upwardly open space, at the lower side of which is a drainage 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', a silicone elastomer spring element 52 is inserted, which is shaped like a section of pipe. Inside, it forms a sealing tunnel 53 that surrounds the area of ​​the spout opening in the base element 20' and the inlet tube 11' of the spout element 10, thereby sealing the entire intermediate space between the base element 20' and the spout element 10' against liquids. To this end, both the upper and lower edge areas of the spring element 52 are pressed tightly into annular grooves in the base element 20' or in the spout element 10'.

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

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

[0093] Figure 16 shows the spout element 10' viewed from below. At the center of the base element 10' is the spout opening 15'. In this case, the inlet tube 11' consists of two segments 11.2' and 11.3', between which there is a gap on either side in which the support bridge of the base element can be housed. While segment 11.2' is rigidly connected to the base element 10', the other segment 11.3' is elastically brought against the base element so that it can be pushed inwards, towards the center. Ribs 11.1' on the inner side of segments 11.2' and 11.3' extend radially inwards until the mushroom-shaped head of the sealing element can be positioned at the center. A chamber 11.4' is formed between each pair of ribs 11.1'. This chamber allows liquid or air to pass in front of the mushroom-shaped head.The fact that several 11.4" chambers are designed around the circumference, specifically in at least two diametrically opposed positions, allows for the guidance of outgoing liquid and the air that subsequently flows into separate channels. In the case of the 100" closure unit, this avoids the typical gurgling that occurs when drinking from bottles with a narrow neck.

[0094] Figure 13 shows the beginning of the opening of the closing unit 100'. This is triggered by pushing the button 34' downwards. By doing so, the cam 35' is disengaged from the edge of the spout 12' and the stop mechanism 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 fully open. The bracket 33' has been pivoted downwards as far as it will go, thereby simultaneously bringing the cover element 32' into a lateral position against the base element 20'. The spring element 52 can be released by pivoting the cover, thereby sliding the spout element 10' vertically upwards, thus creating a larger gap between the spout element 10' and the base element 20'. The central sealing element 51' with its head shaped mushroom 51.1' is moved away from the pouring opening 15' by the movement of the 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 tube 11' has passed through the sealing tunnel 53.

[0097] Figure 15 shows how the spout element 10' can be removed vertically upwards. The inlet tube segments 11.2' and 11.3' are pushed against each other. A projection 11.5' is formed against segment 11.3', which engages under the cover section 23'. Once the projection 11.5' is deployed, the form cooperation joint 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 tube which serves as a spring element 52' and forms the sealing tunnel. Reference signs#:
