Abstract
Description
Technical Field
[0001] The invention relates to a twist-off closure system for a container, preferably a drinking container, comprising a closure which is designed to close an opening of the container, can be sealingly fixed to a rim region of the container and is arranged between a fixedly mounted ring device and a rotatably mounted ring device by means of a threaded mechanism, so that a rotational movement of the rotatably mounted ring device is converted into a vertical movement of the closure, so that one or more openings in the closure can thereby be opened and closed again. Background Art
[0002] Capping devices for covering openings in drinking vessels, in particular glasses or cups, which consist of lids / covers that can be placed on the openings in the drinking vessels are known and are used, for example, in outdoor beverage services. Also known are various covers for disposable and reusable bottles. These are, for example, plastic / plastic covers with an internal thread. Due to various environmental protection requirements, the latter must be fixed to the bottle with a tether (tethered caps) in order not to burden the environment as a separate cover and to be disposed of with the bottle as a mandatory disposal.
[0003] Despite this, plastic / plastic caps or closures are still often discarded into the environment after use, further exacerbating plastic pollution. Therefore, the European Union (EU) has issued a new directive called "Tethered Caps". The directive stipulates that from July 3, 2024, all single-use beverage packaging made entirely or partially of plastic and with a capacity of no more than three liters must be equipped with so-called "Tethered Caps".
[0004] When these drinks are consumed outdoors during the summer months, for example in beer gardens or at sporting events, contaminants often enter the drinking vessels which have not yet been emptied and then have to be removed laboriously. Insects in particular, especially bees or wasps which like to inhabit drinking vessels filled with sweetened drinks, can pose a health hazard.
[0005] Also known are closures with a button / slide mechanism, for example for insulated bottles and insulated cups. Most existing closure systems have such complex mechanical structures that they cannot be cleaned or cannot be cleaned adequately. In addition, existing systems are often subject to wear and tear and / or are expensive to produce.
[0006] To solve this problem, for example, DE 202013010450 U1 describes a closure device for closing a drinking vessel, which comprises a lid part, which is hinged to a clamping device by means of a hinge, and the clamping device is used to releasably fasten the lid to the upper edge of the drinking vessel. The lid also has an opening through which a drinking straw is guided.
[0007] US 9,038,850 B1 has also disclosed such a closure device for closing a drinking vessel, in which an articulated joint is fixed to the drinking vessel by means of a clamping device which rests only against the periphery of the drinking vessel and avoids the upper edge of the drinking vessel. Since the lid usually rests only on the edge area of the drinking vessel, no seal can be achieved, which means that liquid can spill when the drinking vessel is moved, for example during walking.
[0008] In addition, capping devices are also used for disposable hot beverage cups, such as those often provided to customers by beverage and restaurant stalls to take away. These hot beverage cups are filled with warm hot beverages such as coffee or tea. During transportation, it is necessary that the beverage does not spill, so it is often provided with a lid.
[0009] Since such disposable drinking cups are often carried while walking or in a moving motor vehicle and drinking from the disposable drinking cup with the disposable drinking cup cover placed thereon is also done through the corresponding opening, the cup cover serves as a splash guard to prevent the drink from splashing, in particular when the disposable drinking cup is being transported.
[0010] According to DE 202014003467 U1, in order to close the lid, it is pushed over the rim of the cup so that the circumferential groove receives the upper rim of the cup flush.
[0011] The insulated cup is used for hot or cold drinks and has, for example, a disposable insulated cup with a wall made of expanded polystyrene and a separate lid.
[0012] Furthermore, GB 2420265 A discloses a one-piece combination of a drinking vessel and a closure element, wherein a connection in the manner of an integral hinge allows the desired pivoting movement.
[0013] DE 20118188 U1 describes a drinking cup, which has a detachable lid or a pivotally connected lid to the drinking cup and a disk located below the lid, wherein the lid and the disk close the interior of the drinking cup from above in a closed position, the lid and the disk are implemented in two parts, the disk can be detached from the drinking cup or pivotally connected to the drinking cup, the disk has at least one opening, and the lid has at least one closable drinking opening, and the lid and the disk can be twisted relative to each other in order to open or close the drinking opening, so that for opening, at least one opening in the disk can be placed in alignment with the at least one drinking opening so as to release the interior space of the drinking cup to the outside.
[0014] WO 2010 / 003259 A1 describes a closure for a beverage container, wherein the closure has an insertion element and a closure body that can be inserted into the closure opening of the insertion element. The first engagement structure installed on the inner side of the insertion element can be connected to a second engagement structure arranged outside the closure body. The insertion element also has a funnel area above the first engagement structure. The closure body also has a closed top surface, a gripping element and a skirt with an outlet opening. These engagement structures are formed so that the closure body can move between a first position and a second position in a vertical direction relative to the insertion element, in which the closure body seals the closure opening and in which the outlet opening is a liquid release channel.
[0015] DE 202020106281 U1 in turn describes a drinking container for storing, transporting and dosing (in particular drinking) liquids, the drinking container having: a drinking vessel that can be filled with liquid via an opening and wherein the drinking vessel has an opening and a vessel thread; and a closure device for completely opening and closing as well as partially opening the drinking vessel, the closure device comprising: a cover element forming a closure surface to prevent liquid from passing through, wherein the cover element has a sealing area for being placed at the edge of the drinking vessel so that it is possible to place the sealing area at the edge of the drinking vessel in a liquid-tight manner; at least one fixing element for releasably fixing the closure device, which wherein the at least one fixing element is connected to the cover element, and wherein the at least one fixing element has a closing thread which is formed so as to establish a mechanical connection with the drinking vessel in such a way that it meshes with the vessel thread so as to be releasably fixed, wherein the closure device is formed so as to be moved relative to the drinking vessel by loosening the at least one fixing element at the closing thread or the vessel thread in such a way that a through opening for the passage of liquid is formed, the through opening forming a transition between the interior and the exterior of the drinking vessel via a sealing area, wherein in the closed state the interior of the drinking vessel forms a continuous volume, characterised in that the through opening is limited only by the cover element and the drinking vessel.
[0016] The capping systems known from the prior art often have the disadvantage of being cumbersome to operate, especially for hot drinks. Moreover, in practical applications, a movable connection between the drinking vessel and the lid is almost impossible to achieve. Even if such a movable connection can be achieved, it is usually not smooth and inconvenient for the user to use. Furthermore, there is no known sufficiently complete twist capping system in the prior art that can be simultaneously applied to a variety of media in different physical states, such as liquid, crystal, powder, oily and viscous media.
[0017] In addition, existing insulated cups in the prior art generally include a cup body and a cup cover arranged at the mouth of the cup body. When the cup cover is located at the mouth of the cup body, a closed space is formed in the insulated cup. The cup cover is generally screwed onto the cup body or fastened accordingly. The cup cover can be closed by pressing the cup cover downward, and opened by pressing a button switch. However, when the cup cover is opened by pressing the button, the cup cover is completely opened. When the cup cover of the insulated cup containing boiling water is opened, the steam in the insulated cup is ejected upward. As a result, consumers may be scalded during use, which endangers consumer safety. Summary of the invention
[0018] The object of the present invention is to provide an improved closure system for containers, in particular drinking containers, which on the one hand is suitable for containers filled with hot or cold liquids and on the other hand overcomes the above-mentioned disadvantages.
[0019] This object is achieved according to the invention by a twist-off closure system having the features of claim 1. Further embodiments and advantageous embodiments of the invention are to be found in the dependent claims. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Figure 1A container (4) is shown, which is suitable, for example, for storing and / or transporting liquids or powders. The container (4) is closed by a twist-off capping system according to the invention. For this purpose, a rotationally fixed and thus fixedly mounted holding device (1) is first placed on the container (4) in a releasable manner. In one embodiment, the holding device can also be fixed on the container (4) in a suitable manner. The rotationally fixed holding device (1) is connected to a ring device (2) that can be rotated from the outside, for example, via a thread (10). Between the rotationally fixed holding device (1) and the ring device (2) that can be rotated from the outside, a threaded spindle (3) as the actual axially movable cap is surrounded in such a way that the first external rotational movement of the rotatable ring device (2) is mechanically transmitted to the threaded spindle, so that the threaded spindle moves upward along the longitudinal axis (15), for example gradually, thereby exposing one or more through openings (11). This allows, for example, liquid to flow from the container through the interior of the threaded spindle (3) and then to flow to the user's mouth via the through opening (11). The drinking flow can be advantageously assisted, for example, by a funnel-shaped geometry (6) of the rotationally fixed retaining device (1) facing the inside of the threaded spindle. The rotational movement of the threaded spindle (3) in the opposite direction causes the threaded spindle (3) to move downward again as a closure, which leads to a closure, for example a gradual closure, of the one or more through-openings (11). For this purpose, a suitable thread structure (7) is provided between the ring device (2) which can be rotated from the outside and the threaded spindle (3). For example, by means of a suitable system consisting of a spring (8) and a groove (9), the twist-off capping system according to the invention ensures that the threaded spindle (3) can only be moved up and down or forward and backward to a limited extent in the axial direction. This mechanism can be assisted by means of a suitable structure for locking the threaded spindle (3) in the fully open state and in the fully closed state (12). In addition, one or more seals (14) can further seal the twist-off capping system according to the invention at suitable points. The drinking area itself can be basin-shaped (13), as shown here, or flat. In any case, the top surface of the thread spindle (3) ends in a form-fitting manner with the drinking area. Figure 1 In an embodiment, all components are arranged so as to form a common rotational axis and / or longitudinal axis (15) about which the mechanism moves. In an alternative embodiment, the top surface of the threaded spindle (3) is shaped to fit the rim of the twist-off closure system and terminates completely, so that in this case no basin-shaped or flat drinking area is formed. On the contrary, in this embodiment, the user drinks directly from the rim area of the threaded spindle closure; this depends on the extent to which the corresponding opening of the threaded spindle is opened outwards and thus released.
[0045] Figure 2A container (4) is shown, which is suitable, for example, for storing and / or transporting liquids or powders. The container (4) is closed by a twist-off closure system according to the invention; however, another embodiment of the invention is used here. In this case, a rotationally fixed and thus fixedly mounted holding device (1) is first placed on the container (4) in a releasable manner. In one embodiment, the holding device can also be fixed to the container (4) in a suitable manner. The rotationally fixed holding device (1) is in turn connected, for example, via a thread (10) to a ring device (2) that can be rotated from the outside. Between the rotationally fixed holding device (1) and the ring device (2) that can be rotated from the outside, a thread spindle (3) as the actual axially movable closure is surrounded in such a way that a first external rotational movement of the rotatable ring device (2) is mechanically transmitted to the thread spindle, so that the thread spindle moves upwards along the longitudinal axis (15), for example gradually, thereby exposing one or more through-openings (11). This allows, for example, liquid to flow from the container (4) through the interior of the thread spindle (3) and then through the through-opening (11) to the mouth of the user. The drinking flow can be advantageously assisted, for example, by a funnel-shaped geometry (6) of the rotationally fixed retaining device (1) facing the inside of the threaded spindle (3). A rotational movement of the threaded spindle (3) in the opposite direction in turn causes the threaded spindle to move downwards again as a closure, which results in a closure, for example a gradual closure, of the one or more through-openings (11). For this purpose, a suitable threaded structure (7) is provided between the ring device (2) which can be rotated from the outside and the threaded spindle (3). For example, with the aid of a suitable system consisting of a spring (8) and a groove (9), the twist-off closure system according to the invention ensures that the threaded spindle (3) can only move up and down or forward and backward to a limited extent in the axial direction. In addition, one or more seals (14) can further seal the twist-off closure system according to the invention at suitable points. The drinking area itself can be basin-shaped (13), as shown here, or flat. In any case, the top surface of the threaded spindle (3) terminates in a form-fitting manner with the drinking area. In Figure 2 In an embodiment, all components are arranged so as to form a common rotation axis and / or longitudinal axis (15), about which the mechanism moves.
[0046] Figure 3 A to Figure 3 D shows a schematic perspective plan view of the basic mechanism of the twist closure system according to the present invention. Figure 3 A shows as an example that the anti-clockwise rotation of the ring device (2) which can be rotated from the outside leads to the opening of the central thread spindle (3), i.e. the actual closure. The process of slowly opening the closure, i.e. the thread spindle (3), upwards is shown in FIG. Figure 3B, wherein the one or more through-openings (11) are open to the outside and allow, for example, drinking to the user. When the ring device (2) which can be rotated from the outside is rotated in the opposite direction, in this case in the clockwise direction, the cover in the form of the threaded spindle (3) is retracted again and the through-openings (11) are closed again, for example gradually; see Figure 3 C. From Figure 3 The subsequently completely closed state of the closure cap / thread spindle (3) can be seen in D. The top surface of the closure cap / thread spindle (3) is form-fitted to the drinking surface and sealed.
[0047] for Figure 4 , applicable is the same as above Figure 2 The same reference numerals and descriptions are not repeated here for the sake of brevity. Figure 4 Additionally shown is a detachable locking element (16) for the threaded spindle (3) according to the invention, in order to prevent the threaded spindle (3) from being unintentionally screwed out.
[0048] for Figure 5 , applicable is the same as above Figure 1 The same reference numerals and descriptions are used herein for the exemplary drinking bottle or reusable bottle and are not repeated here for the sake of brevity. Figure 5 A further embodiment of the present invention is additionally shown without the basin-shaped drinking area (13) for a simple drinking bottle. In this case, the closing surface of the thread spindle (3) ends in a close fit with the edge of the bottle neck. Figure 5 The left figure shows the threaded spindle (3) in the closed state as a cover. Figure 5 The right figure shows the open state of the threaded spindle (3) of the cover; the vertical movement direction is indicated by the upward arrow.
[0049] for Figure 6 , applicable is the same as above Figure 1 and Figure 5 The same reference numerals and descriptions are used herein for the exemplary drinking bottle or reusable bottle and are not repeated here for the sake of brevity. Figure 6A further embodiment of the present invention is additionally shown: in this case, the function of the rotationally fixed holding device (1) is assumed by the design of the container (4) itself in the bottleneck area. This means that the bottleneck is designed to replace the function of the rotationally fixed holding device (1). Therefore, the ring device (2) that can be rotated from the outside can rotate directly around the bottleneck. This is accompanied by at least the following technical advantages: this allows a more inexpensive production of the twist-on capping system according to the present invention and can be implemented in an environmentally friendly manner, for example, directly in a reusable bottle. Therefore, the twist-on capping system is non-detachable and remains at the bottle. This ensures that the cap will not be lost and will not exist in nature as plastic / plastic waste. This meets the requirements of the EU for a capping system fixedly connected to a bottle. In addition, in certain embodiments, the capping system according to the present invention can be designed in terms of material so that the capping system can be frequently cleaned and reused in a reusable sense. Figure 6 The left figure shows the threaded spindle (3) in the closed state as a cover. Figure 6 The right figure shows the open state of the threaded spindle (3) of the cover; the vertical movement direction is indicated by the upward arrow.
[0050] for Figure 7 , applicable is the same as above Figure 1 and Figure 5 The same reference numerals and descriptions are used herein for the exemplary drinking bottle or reusable bottle and are not repeated here for the sake of brevity. Figure 7 A further embodiment of the present invention as a closure for a drinking bottle or a reusable bottle is additionally shown: in this case, the threaded spindle (3) is designed as an elongated strip as a closure element, and its closure surface (similar to a lid) is placed on a ring device (2) that can be rotated from the outside. The closure surface ends flush with the bottleneck end of the drinking bottle shown. This brings at least the following technical advantages: the entire area in contact with the liquid is completely covered by the threaded spindle (3) in the closed state (left figure), so dust and dirt cannot accumulate in this area. This generally improves the hygiene of drinking. Any liquid residue at the edge of the closure is completely covered by the threaded spindle after closure and will not dry and / or spread to form stains. This again improves the hygiene of drinking. Figure 7 The left figure shows the threaded spindle (3) in the closed state as a cover. Figure 7 The right figure shows the open state of the threaded spindle (3) of the cover; the vertical movement direction is indicated by the upward arrow.
[0051] In a further embodiment, the twist closure system according to the invention has means for acting as an original closure. This means that, for example, a material layer is installed in the twist closure system in a suitable manner so that it is torn or otherwise destroyed when the twist closure is used for the first time, in order to prove to the user that the closed container was indeed closed before this. It is conceivable that, for example, the material layer is in the thread of the twist closure system according to the invention and / or around the thread spindle. It is also conceivable to install the material layer in and / or around a rotatable ring device, wherein the first manipulation thereof changes or destroys its integrity, preferably accompanied by a sound, indicating to the user the originality of the closure.

[0091] 29. The twist closure system according to any of the preceding embodiments 14 to 26, characterized in that the closure (3) is recessed in a form-fitting manner into a planar surface, preferably a drinking surface.
[0092] 30. A twist cap system according to any one of the preceding embodiments 1 to 29, characterised in that the container (4) is a bottle, in particular a drinking bottle or an insulated bottle; a cup, in particular a drinking cup; a bucket; a basin, in particular a washbasin or a bathtub.
[0093] 31. A twist-off closure system according to any one of embodiments 14 to 30, characterised in that the rotationally fixed holding device (1) itself is an integral part of the container (4).
[0094] 32. The twist capping system according to any one of embodiments 14 to 31 is characterized in that the threaded spindle (3) is designed to be elongated and is placed as a cap on the rotatable ring device (2) or the rotationally fixed retaining device (1).
[0095] In some embodiments of the invention, the threaded spindle can be disassembled from the ring device and the retaining device. In some embodiments, alternatively or additionally, the ring device can be loosened from the retaining device. Thus, all three components: threaded spindle, ring device and retaining device can also be disassembled into individual parts, which can therefore be cleaned particularly advantageously.
[0096] In some embodiments, the threaded spindle is enclosed in a ring arrangement and a retaining arrangement so that it cannot rotate about itself (cannot rotate horizontally), but is locked and can only be moved vertically along the longitudinal axis by movement of the rotatable ring arrangement.
[0097] In one embodiment, the ring device and the retaining device are releasably connected to each other via a suitable bayonet connection.
[0098] In one embodiment, the threaded spindle is enclosed in a retaining device and a ring device in the form of a suitable bayonet connection.
[0099] The preferred material for producing the threaded spindle and / or the ring device and / or the retaining device is polypropylene (PP). This is a low-cost material that just allows all three components to be produced with PP.
[0100] Advantageously, thanks to the twist closure, the invention provides a closure system that is easy to use and can be produced in a cost-effective and environmentally friendly manner.All suitable plastic and / or natural materials are conceivable for producing the twist closure system.
[0101] Furthermore, the twist closure system can be used universally according to the invention. A non-exhaustive list includes: bottles enclosing liquids such as beverages and / or foods such as olive oil, barrels of any type, urns, etc. The twist closure system is also suitable for use as a drain in a washbasin and / or bathtub. Likewise, the twist closure system according to the invention is also suitable for use in dosing ventilation, for example in an aircraft cabin.
[0102] Due to its structural design, the system is easy to clean, or in other words, is not susceptible to dirt. In addition, the unique structure of the system makes it less prone to wear and malfunction.
[0103] According to the invention, the thread formed between the fixedly mounted ring means and the rotatably mounted ring means can be formed as a thread capable of endless rotation or rotation to a limited extent. Only the retaining groove of the closure, its arrangement in the rail system and the positioning of the protrusions for retaining the position are decisive in limiting the vertical movement of the closure.
[0104] Advantageously, the closure itself is formed as a cylindrical hollow body acting as a stopper or plug, which is arranged to be able to move vertically in the twist-closure system. Other forms can be envisaged by those skilled in the art.
[0105] Furthermore, advantageously, the twist closure system according to the invention allows to improve the safety of the transport of media such as water, tea, oil, powder, sugar, pepper, cream, etc. According to the invention, the twist closure system is an absolutely mechanically tight closed twist closure structure. During transport, the twist closure cannot be accidentally opened.
[0106] Another advantage of the twist-off closure according to the invention is that hygiene is improved and the handling is very quick and easy.
[0107] In the above background it should be stressed that the exact arrangement of the fixedly mounted ring means and the rotatably mounted ring means is not critical to the closure system, as long as the formation of the threads for the twisting mechanism and thus the vertical movement thereof for conversion into closure is provided.
[0108] All suitable sealing materials and designs can be used as seals for the twist-off closure system according to the invention. For example, a sealing rubber lining or a rubber ring. Silicone-based seals etc. are also conceivable.
[0109] It should be emphasized once again that universal application is possible for the twist closure system according to the invention. This applies both to the closure of containers such as bottles and cups and also to the closure of washbasins, bathtubs, etc. The invention is not limited in this respect.
[0110] The above description contains many specific details for a complete understanding of the present invention. However, the present invention may also be implemented in other ways different from this description, and therefore this description cannot be understood as limiting the scope of protection of the present invention.
[0111] Although the present invention has been described with reference to the above advantageous embodiments, it is obvious that those skilled in the art may make various changes and modifications without departing from the scope of application of the present invention. Therefore, these changes are covered by the protection scope of the present invention.
