Description

The invention relates to a lid unit for a drinking container according to the preamble of claim 1. The lid unit has a lid body with two openings, one of which is a large diameter compared to the other. The large-diameter opening is provided for coupling with a drinking container, while the other, small-diameter opening is prepared for receiving a crown cap. The crown cap in turn is intended, in a state in which the lid is coupled to the drinking container, preferably to be placed on the lid by an industrial plant.

Furthermore, part of the invention is a drinking container unit, which is composed of a drinking container and a lid unit.

The invention further relates to a method for placing a crown cap on a lid body which is placed on a drinking container.

After production, consumable liquids, such as beverages, are transferred to containers / bottled in a bottling plant to enable logistically efficient delivery of the beverages to various locations. Frequently, a beverage in the bottle is transferred to a drinking container, such as a glass / cup / etc., before being consumed. The reason for this is, inter alia, that a glass generally has a further drinking opening than a bottle, which allows for increased drinking pleasure.

Beverages, especially carbonated beverages, such as beer, are bottled in industrial bottling plants, as are well known in the art. Here, at the end of the filling process, the closure of the container with a closure element. As a particularly advantageous closure element, especially in beers, a crown cork has crystallized out.

As a further development, it can be observed that glass as a material for a container is increasingly losing importance. The reason for this is on the one hand the slight fragility, which carries a high risk of injury and a security risk. Another disadvantage of glass as the material of a container is the high mass, which requires, for example, a higher energy input during transport. In the end, glass also loses its importance because, for example, high temperatures are required for melting. These aspects challenge the perceived ecological balance of glass.

From the prior art generic cover units are known. Thus, the European patent discloses EP 2 161 206 B1 a dome-shaped attachment, which is prepared for receiving a crown cap and further clamped onto a body. A cover flange is in this case mechanically aufklemmen on an upper edge of the body that they are rigidly coupled together. The high forces acting on the attachment when placing the crown cork can therefore be absorbed by that device, since they are metal components.

So that plastic containers are closable by means of a crown cap, various approaches are disclosed in the prior art. One of them is from the international patent application WO 2014/096869 A1 known. Here, a part of a bottleneck made of glass is so coupled with a projection of a plastic neck that the final bottleneck consists partly of glass and partly of plastic. The force acting on the bottleneck when placing the crown cap is thus absorbed by glass.

Also the German publication DE 1 607 950 A1 is aimed at sealing plastic bottles. Here, a thick-walled configuration of a plastic bottle, which would be necessary to compensate for the force acting on the bottle neck when placing the crown cap, bypassed so that the first crown cap is placed on the bottle head separated from the bottle before the unit from the bottle head and crown cap is welded to an opening edge of the bottle.

Furthermore, the publications are DE 10 2010 015 017 A1 such as WO 2012/022 475 A1 to settle on the state of the art.

The present invention is in view of this prior art, the object to disclose a cover unit, which is reversibly coupled with a large diameter drinking container, so that after removal of the lid increased drinking pleasure whether the wide opening of the drinking container allows. On the other hand, the object to be fulfilled is that the cover unit can be closed with a crown cap in order to be able to profit from the advantages of the crown cork. Finally, the invention is also exposed to the task of revealing a light as possible and easily recyclable cover unit. In addition to the cover unit itself, the invention is further based on the object of disclosing a method for placing a crown cap on a lid body, which is already coupled to a drinking container, as well as a resulting drinking container unit.

This object is achieved by means of a cover unit with the features of claim 1, by means of a method having the features of claim 9 and by means of a drinking container unit having the features of claim 10. Advantageous embodiments are the subject of the dependent claims.

In particular, the following advantages can be derived from this embodiment of the cover unit and the drinking container unit according to the invention:

• - Due to the two openings, which has the lid unit, a beverage can be emptied both via a small diameter, sealed with a crown cap opening, as well as a large diameter opening.
• - The lid unit is rigidly coupled to the drinking container via the thread at any time or detachable from this.
• - After the coupling between the lid unit and the drinking container, the drinking container unit can be filled in a bottling plant and then closed by a crown cap.
• - The cover unit is detachable via a screw from a consumer without much effort from the drinking container.
• - After loosening the cover unit results in a drinking pleasure for the consumer, which otherwise results only in a glass, which in particular, when it comes to the container contents to wheat beer, has great taste in terms of taste.
• - The drinking container is designed so that it meets the requirements specified in the standard DIN 6075: 1997-05 outside dimensions and thus can be conveyed in conventional filling equipment.
• - The upper end section of the cover unit has the dimensions required by the standard DIN EN ISO 12821: 2015-08, which means that it can be filled with conventional filling systems.
• For a consumer, a drinking-glass geometry, which is oriented towards a beer glass, creates a drinking sensation identical to that of a conventional beer glass.
• - The cover unit is not dependent on such features in terms of their geometry that would cause a screw.

The subject of the invention is therefore a cover unit with a lid body, which can be coupled to a large-diameter lower end portion with a drinking container and which is prepared at a small-diameter upper end portion for receiving a crown cork. According to the invention, the lower end portion has a thread, so that the lid body can be screwed onto the drinking container. The lid body can also be unscrewed from the drinking container by means of the thread. Thus, the screw connection between the two components entails a reversible closure of the drinking container, so that a consumer reacting to all circumstances has either a drinking container with a wide opening or a closed container unit.

It is also advantageous if the lid body is materially / integrally made of a plastic material such as polyethylene terephthalate (PET), polylactide (PLA), styrene-acrylonitrile (SAN), high density polyethylene (HDPE) or other food grade plastics. Thus it is possible to produce the lid body by means of an injection molding process. Here, a plastic is liquefied and injected into a mold corresponding to the negative of the lid body, under pressure. In this way, high quantities can be produced under high precision, with no or virtually no waste produced.

The thread is prepared to forward a force introduced into the drinking container when the crown cap is placed on the lid body in the upper end section. Thus, the thread according to the invention, in addition to the task of carrying out a reversible coupling between the cover unit and the drinking container, fulfills the additional function of force transmission in the crown capping method. Thus, the thread is dimensioned such that the high forces acting on Kronkorkenaufsetzverfahren be transferred to the drinking container. This requires that the lid body is already placed on the drinking container when the bottle cap is placed, which is the case according to the invention.

The lid body according to the invention is also exposed to high forces before and during a filling process during which a beverage is filled into the drinking container, ie before Kronkorkenaufsetzverfahren. These result from the fact that before the filling process inside the unit of drinking container and lid body, an overpressure is build up to prevent or at least mitigate foaming during the filling process. In order for this pressure in the unit of drinking container and lid body is adjustable, the unit is exposed to additional clamping. This entails a stress on the unit, which is compensated by the inventive design of the lid of this. Thus, the unit of drinking container and lid body is dimensioned such that not only the high forces acting during the Kronkorkenaufsetzverfahrens, but also compensates for the forces resulting from the Überdruckeinstellverfahren.

As soon as the outer diameter of the lid body between the upper end portion and the lower end portion increases continuously from top to bottom, preferably progressively, it is possible to that the lid body without any plastic deformation of the force acting on it in Kronkorkenaufsetzverfahren, passes on to the drinking container. The portion between the upper and lower end portions is referred to as a connecting portion. The length of the connecting portion along the longitudinal axis of the lid unit exceeds the respective lengths of the upper end portion and the lower end portion. Thus, the ratio of the length of the connecting portion to the diameter extension, which is made by the connecting portion is greater than 0.5, preferably greater than 1. Under diameter extension is understood here as the difference between the diameter of the large diameter lower end portion and the small diameter upper end portion. From the terminology outside diameter also shows that the lid body is configured rotationally symmetrical.

In a further embodiment, the length of the connecting portion is also shorter than disclosed by the above-mentioned conditions. By means of the use of struts, which are described in more detail in the context of this application and / or an increase in the material thickness of the lid body, it is thus possible that the connecting portion is designed shorter in length than the upper and / or the lower end portion.

In a further advantageous embodiment, the lid body has at least one strut in the interior, which preferably extends exclusively along the longitudinal axis of the lid unit and which is prepared to increase the rigidity of the lid unit. The brace is adapted to the geometry of the connecting portion and that of the lower end portion such that it acts as a stabilizer in the crown capping method. Advantageously, the strut is designed as a kind of rib, which receives on the one hand an axial force, on the other hand in the radial direction is at least partially compliant. Thus, a placement of the lid body on the drinking container without much effort is possible and it is timely avoided the risk of buckling Kronerkorkenaufsetzverfahren.

In particular, when the strut in a plane along the longitudinal axis of the cover unit, ie the frontal plane of the cover unit, substantially has a triangular shape, the strut fulfills its stabilizing function reliably with low material usage. Here, the hypotenuse of that triangular shape of the brace is primarily responsible for converting the compressive force acting during the crown capping process from axial to radial force. This radial force can be forwarded by means of the thread according to the invention to the drinking vessel, which in turn emits it to the environment, so that the power flow is closed.

It is also advantageous if several struts are arranged equidistantly in the circumferential direction. Thus, an even distribution of the force of the Kronkorkenaufsetzverfahrens is feasible, which prevents the occurrence of local stress peaks and thus increases the life of the cover unit.

In particular, when the introduced during the placement of the crown cap on the lid body in the upper end portion force is at least partially introduced in the axial direction acting on an upper bracing portion in the brace and at least partially discharged in the radial direction of the brace by a lower bracing portion, the brace allows a Efficient force transfer, which increases the strength of the entire lid body. The upper and lower bracing sections are more rigid in the axial direction than in the radial direction. This allows for the inclusion of high crown corking process forces with radial compliance.

Advantageously, the lower end portion has an inner lip which is prepared to be disposed inside the drinking container and has an outer lip which is prepared to be located outside of the drinking container. Accordingly, a drinking circulation edge of the drinking container is arranged in the corresponding state between these two lips. Thus, the two lips define a gap in which preferably a seal is arranged, which allows a fluid-tight sealing between the interior of the drinking container and the environment. The two lips are pivoted to each other in a certain angular range, whereby the lid body increases in its overall stability. For example, if such a high force is introduced to the upper end portion, that the inner lip is moved radially outward due to the force diversion of the strut, the outer lip counteracts this radial movement and thus stabilizes the cover unit.

Once the inner lip has the thread according to the invention as an external thread that is prepared to be in contact with an internal thread of the drinking container and / or as soon as the outer lip is prepared to at least partially in contact with the drinking container to stabilize on the To act drinking container, the corresponding design of the respective lip has a positive effect on the strength of the lid body. Likewise, in this embodiment calls the introduced during the placement of the crown cap on the lid body in the upper end portion force at least temporarily a radial movement of the inner lip, which is compensated / blocked by the drinking container and the outer lip. As an alternative to the internal thread, it is within the scope of the inventive idea also possible to design an external thread for receiving the lid body on the drinking container. In this embodiment, in order to further facilitate the coupling between the lid unit and the drinking container, the corresponding mating thread of the lid unit is formed as an internal thread on the outer lip.

In particular, when the outer lip is drawn along the longitudinal axis and exceeds in its length along the longitudinal axis the length of the inner lip, the stabilization according to the invention by the two lips can be realized efficiently.

In this case, it is furthermore advantageous according to the invention if the lid body is configured in the form of a step inside, wherein the inner lip represents a first step, which is connected via an angled intermediate region in the connecting section to a second step, which is formed by the upper end region. Thus, the cover shape, which can be described approximately as a bell shape, has defined edges which can be configured such that they can withstand high loads. Thus, those edges are explicitly designed to perform force direction redirections, which is reflected in a particular embodiment of the corresponding edges.

The invention likewise relates to a method for placing a crown cap on a lid body, so that a drinking container unit is formed, which is composed of a drinking container and a lid unit according to the invention. The method has various steps, which are preferably sequential in time. First, the lid body is coupled to the drinking container. According to the invention, the connection between the two components is realized by means of a screw cap. It is possible in this case that the lid body is pressed onto the drinking container, bypassing the screwing movement. For this purpose, a certain elasticity of the inner lip of the lid body is required.

After the lid body is coupled / connected / screwed to the drinking container, the crown cork is placed by means of pressure force on the upper end portion. Thus, the drinking container unit is completely formed after placing the crown cap and it requires no further step. When placing the crown cap, the pressure force on the lid body is transferred to the lower end portion. From there, the force via the thread, which is preferably designed as an external thread on the inner lip, forwarded to the drinking container. This passes on the pressure force about a floor to the environment, so that the power flow is closed. As an alternative to the ground, the force can also be absorbed by the filling installation via a gripping arm which engages at any point of the drinking container.

Between the step of coupling the lid unit and the drinking container and the step of placing the crown cork is preferably a filling step. This consists in that a beverage, preferably beer, is filled into the assembly consisting of lid body and drinking container. In addition to beer, other beverages such as wine, carbonated soft drinks, cider, alcoholic mixed drinks and / or non-alcoholic malt beverages are possible as container contents of the drinking container unit according to the invention. Here, the geometries according to the invention are designed such that conventional filling systems with their routes and gripping arms are not adapted to special geometries.

The invention is further directed to a drinking container unit, which is composed of a drinking container and a screwed onto this lid unit. Such a drinking-container unit can be produced by means of an injection-molding process, except for the crown cork, and has the advantages presented above.

It should also be mentioned that the term "crown cork" is understood to mean, in particular, a closure element which is designed according to DIN standard 6099. The corresponding cover-side counterpart to the crown cap, so the upper end portion is described in terms of its geometry in DIN 6094, wherein the lid according to the invention or the upper end portion is advantageously made of plastic. Such a crown cap is pressed onto the counterpart with a force of the order of 2,000N. Accordingly, the counterpart, which is formed according to the invention of the lid, must have a sufficiently high rigidity. This is achieved by the embodiments of the invention presented above.

Crown caps have a seal on the inside and preferably have an inner diameter between 26mm and 27mm, about 26.75mm and an outer diameter between 32mm and 33mm, about 32.1mm. The height of a crown cap is between 5mm and 7mm, about 6mm. The crown cap is at least partially made of sheet metal having a thickness between 0.2mm and 0.3mm, about 0.235mm.

The invention will be explained in more detail with reference to figures, in which context, various embodiments are explained. These show:

1 a perspective view of a lid unit according to the invention, consisting of a lid body and a crown cap;

2 a side view of the cover unit 1 ;

3 a side view of the lid body with a drawn cut line;

4 : a sectional drawing along the cutting line 3 ;

5 a perspective view of the lid body;

6 : a bottom view of the lid body 5 ;

7 : a drinking container according to the invention, on which the lid body is placed, in a perspective view;

8th : A side view of the drinking container with attached lid body with marked cut line; and

9 : a sectional drawing along the cutting line 8th ,

The drawings are merely schematic in nature and are for the sole purpose of understanding the invention. The individual reference numbers can be interchanged.

In 1 is a lid unit 1 shown. This has a lid body 2 with a large diameter lower end section 3 and a small diameter upper end portion 4 on. While the lower end section 3 a related to 4 further described thread / external thread 5 has, is the upper end portion 4 prepared for receiving a cap. The cap is as a bottle cap 6 formed and forms with the lid body 2 the lid unit 1 ,

2 represents the lid unit 1 out 1 In a side view. It can be clearly seen that it is the crown cork 6 is a standard-compliant bottle cap. Between the lower end section 3 and the upper end portion 4 is a connection section 7 formed. This is in terms of its geometry designed such that it can withstand the high forces that act when the crown cork 6 on the upper end section 4 placed on / pressed / clamped, so to the lower end portion 3 further, that a through and / or buckling, the plastic deformation of the lid body 2 causes, is prevented. Running from top to bottom is the outer diameter of the rotationally symmetrical connection section 7 progressively increasing. The along the axis of rotation 8th of the lid body 2 running length of the connecting portion 7 exceeds the length of the lower end section 3 and also the upper end section 4 ,

The outer diameter of the lower end section 3 indicates the length of the lower end section 3 a substantially constant value. The length of the lower end section 3 exceeds the maximum material thickness of the lid body 2 by a multiple. Preferably, the length of the lower end portion 3 in the range between 0.5cm and 3cm, about 1.2cm. In this way, a grip surface forms 9 , which is sufficiently large to be umgreifbar for a consumer so that the cover unit 1 from one to the other 7 to 9 illustrated drinking container 10 can be reversibly solved.

The upper end section 4 is shaped such that it receives a crown cap 6 is suitable and has the necessary dimensions. The upper end section 4 forms a filling nozzle, through which a drinking container unit according to the invention, consisting of the lid unit 1 and the drinking container 10 is composed, is fillable.

In 3 is the lid body 2 out 2 without the bottle cap 6 shown. Thus, the outer shape of the upper end portion 4 visible, noticeable. The upper end section 4 has a bead 11 on top of the bottle cap 6 is put on in a Aufsetzverfahren. Below the bead 11 has the upper end portion 4 a bulky grandeur 12 on. The grandeur 12 is prepared to gripping the lid body 2 in the bottling plant when he is on the drinking container 10 is set to allow by a gripping arm. The respective geometries of the bead 11 and the grandeur 12 are therefore preferably defined by standards, so that the upper end portion 4 has such dimensions that it does not differ from commercially available filling nozzles, as it is known, for example, from a Euro bottle, an NRW bottle, a Longneck bottle or a Vichy bottle.

Below the upper end section 4 its lower end through the bulbous grandeur 12 is defined, the connection section begins 7 , This points at the transition point to the upper end portion 4 a small diameter, which then up to the transition to the lower end portion 3 steady increases. That increase is preferably progressive. The progressive increase allows forwarding of the force when putting on the crown cork 6 on the lid body 2 acts, to the thread 5 without the lid body 2 is plastically deformed. Thus, the inventive geometry of the connecting portion causes 7 that the bottle cap 6 on the lid body 2 , which is preferably made of a plastic material, can be placed only under slight elastic deformation. For this purpose, the length of the connection section exceeds 7 along the longitudinal axis of the lid body 2 each the length of the upper end portion 4 and the lower end portion 3 ,

In 4 is a sectional view taken along the section line IV-IV 3 shown. Furthermore, in the connection section 7 and in the lower end section 3 struts 13 arranged. These run along the longitudinal direction of the lid body 2 and increase its stiffness. So allow the struts 13 that the force when putting on the crown cork 6 on the lid body 2 acts, by this, at least temporarily recorded. The width of the struts 13 is small compared to its length. Because the braces 13 are not or barely prepared to absorb shear forces, their breadth is not of great importance. The struts 13 are still prepared to in their upper bracing section 24 to absorb an axial force, which they then at their lower strut section 25 to an inner lip 14 predominantly as a radial force. The radial force is inventively on the inner lip 14 attached threads 5 to the drinking container 10 passed.

Furthermore, the lower end portion 3 the inner lip 14 and an outer lip 15 on. These are prepared to a gap 16 define. The gap 16 is prepared to a drinking circulation edge, ie the edge, the opening of the drinking container 10 defined to record. To that connection between the cover unit 1 and the drinking container 10 make such that in the drinking container 10 Existing liquid makes little or no exchange with the environment, is still on the inner lip 14 the thread 5 arranged, which is prepared with an internal thread 23 , this in 9 is shown in detail inside the drinking container 10 to be engaged.

The inner lip 14 and the outer lip 15 are relatively pivotable relative to each other in a certain angular range. So if the bottle cap 6 on the lid body 2 is attached to the lid unit 1 Forming, leads the force when putting the crown cork 6 affects, that the inner lip 14 temporarily deformed radially outward. That deformation is caused by the drinking circulation edge of the drinking container 10 taken up, in turn, from the outer lip 15 is supported. So are the two lips 14 . 15 designed such that they stabilize each other and thus increase the overall stability of the lid body.

In 5 is a perspective view of the lid body 2 shown. The struts 13 are evenly distributed over the circumference. In their form are the struts 13 essentially triangular. In this case, the individual edges are preferably designed to be curved, wherein the hypotenuse advantageously has a turning point in order to optimize the power flow. The wording substantially triangular is thus to be construed broadly and to mean that the bracing is fixed at three connectable points. A transitional edge 17 is prepared to transition between the lower end section 3 and the connection section 7 define. The transitional edge 17 thus allows a stepped transition between the two sections. This one is from the bracing 13 so supported that the lid body 2 when putting the crown cork 6 acting forces withstand a design made of plastics.

In 6 is the lid body 2 shown from below. There are preferably six braces 13 evenly distributed around the circumference of the lid body 2 arranged. Alternatively, other numbers of struts, such as 2, 3, 4, 7, 8, 10, 15 or even more are possible. In the radial direction of the lid body 2 each stretches a strut 13 in about half the length of the lid body radius. Since the lid body 2 at the top inside the bead 11 having an opening is thus a large part of the lid body 2 in the radial direction of the struts 13 strengthened. 6 also clarifies about recesses 18 on. These are in the thread 5 appropriate; so that this is a pressure relief thread, the unscrewing of the cover unit 1 from the drinking container 10 allows without the contents of the drinking container 10 overflows.

A gap width 19 that is the width of the gap 16 is preferably wider than a material thickness 20 the outer lip 15 , It can be seen that the lid body 2 is designed substantially thin-walled.

In 7 is the drinking container 10 with attached lid body 2 shown in perspective. The length of the lid body 2 along the longitudinal axis is small compared to the length of the drinking container 10 , The drinking container 10 is variable in shape. In a preferred embodiment, it has the form of a wheat beer glass. This is characterized by a slim shape, which is chosen such that carbon dioxide beads, which are present in the drink, preferably in beer, can rise a long distance through the drink to the top and keep it fresh in this way long. Furthermore, there is a floor 21 of the drinking container 2 designed beaded. This allows a hearty bumping at the bottom of the drinking container 2 so the drinking container 2 Even in a design made of plastic the drinking sensation of a glass material causes.

8th shows the lid body 2 on the drinking container 10 screwed in a side view. The lid body 2 corresponds to the in the 3 to 6 described embodiment. The length of the unit from lid body 2 and drinking vessels 10 is chosen so that the unit can be filled with an industrial bottling plant. After filling, the unit is made of lid body 2 and drinking vessels 10 with the bottle cap 6 locked. The transition between the lid body 2 and the drinking container 10 is designed such that a forming between two components stage 22 has a small height compared to the other dimensions. So is the unit of lid body 2 and drinking vessels 10 easy to handle in the bottling plant.

Along the line IX-IX in 8th is a cut made in 9 is shown. The screw connection between the cover unit 2 and the drinking container 10 is through the thread 5 on the inner lip 14 of the lower end portion 3 is arranged, and the internal thread 23 made in the drinking circulation edge. The lid body is preferred 2 so on the drinking container 10 put on / screwed on until the upper end of the drinking circulation edge in the gap 16 touches the bottom of the gap. The internal thread 23 is therefore designed to be somewhat longer, to avoid geometric overdetermination of the two components lid body 2 and drinking vessels 10 to each other. The material thickness of the drinking container 10 is compared to the length of the drinking container 10 low. It is of the same order of magnitude as the material thickness of the lid body 2 ,
