Description

The present invention relates to a beverage packaging according to claim 1.

State of the art

EP 1 431 209 B1 discloses a liquid removal device in a flexible packaging with a straw element which comprises a mouth end and a bag end, and with a locking element which is formed by a truncated cone tapering towards the bag end. A ring is arranged between the mouth end and the latching element, through whose ring surface facing the bag end a stop is formed. The distance between the stop and an annular surface of the latching element facing the mouth end is dimensioned such that a sleeve of a beverage bag, not shown, can be accommodated between the stop and the annular surface.

Alternatively, a plurality of detent webs which are separate from one another can be arranged on a sleeve in which the removal device is accommodated and at the end of which the detent elements are located. The distance between the ring surface of the latching element facing the mouth end and the stop is selected such that when the removal device is pushed back and forth between these two surfaces, the inner film sealingly against the straw element is not displaced relative to the straw element. After the beverage bag has been emptied, the removal device can be pulled out of it.

Alternatively, the removal device can comprise a sleeve, which has two latching webs at its end directed towards the end of the bag, a ring being formed adjacent to the latching webs and above the latching webs, and handle webs extending axially extending above the ring are distributed in the circumferential direction.

task

The invention is therefore based on the object of providing a drinking straw and a beverage packaging which enables the drinking straw to remain in a beverage packaging.

solution

This object is achieved by the beverage packaging according to claim 1. Preferred embodiments and developments are disclosed in the subclaims.

The beverage packaging for holding liquid product includes an insertion area for inserting a drinking straw and the drinking straw. The drinking straw includes a tubular one Culm element which comprises a culm wall, an inlet to be placed in the beverage packaging and an outlet to be placed outside the beverage packaging. At least one latching lug is provided on an outer surface of the culm wall, which is connected to the outer surface of the culm wall towards the inlet and which is spaced from the outer surface of the culm wall towards the outlet. The at least one locking lug is at a distance from the inlet along a longitudinal axis of the drinking straw of at most 30% of a length of the drinking straw.

The provision of at least one locking lug in the lower region of a drinking straw prevents the drinking straw from being lost after it has been introduced into the beverage packaging, but the drinking straw can still be moved up and down to a considerable extent, which simplifies the removal of liquid.

An acute angle can be included between the locking lug and the longitudinal axis.

The at least one latching lug can be provided in such a way that when the drinking straw is introduced through the insertion area into the beverage packaging, when it passes through the insertion area, it reversibly touches the straw wall, i.e. the straw element, can be pressed. When passing through the insertion area, there may be little or no spacing of the at least one latching lug from the outer surface of the stem wall.

After the at least one latching lug has passed the insertion area, that is to say is located entirely within the beverage packaging, the at least one latching lug can return to its starting position relative to the outer surface of the straw wall.

If an attempt is made to pull the drinking straw out of the beverage packaging again after the at least one latching lug has been introduced into the beverage packaging, the at least one latching lug can interact with the inner surface of the beverage packaging in an area around the insertion area such that they pull against the drinking straw the inner surface can be pressed. For example, their spacing from the outer surface of the stalk wall can be partially increased or else remain the same. The at least one locking lug can function like a barb and prevent the drinking straw from being pulled out of the beverage packaging again.

The at least one latching lug can be a spread-apart part of the stalk wall. The locking lug can be produced by a three-sided cutout in the stalk wall, so that the stalk wall can have an opening which can correspond in its dimensions to the locking lug; For example, when a surface is spread out as a flat surface, the latching lug can be rectangular or trapezoidal. Alternatively, the locking lug can be produced by a two-sided cut in the stalk wall, for example in that a cutting device is attached to the stalk wall obliquely, for example at an acute angle with respect to the longitudinal axis, and a cut is made in the stalk wall in the direction of the inlet. Then, for example, a surface of this latch can be triangular when it is spread out as a flat surface. If an attempt is made to pull a drinking straw out of the beverage packaging after inserting the locking lug, which was produced by a double-sided cut in the straw wall, the locking lug can interact with the inner surface of the beverage packaging in an area around an insertion area such that the locking lug is pressed against the inner surface of the beverage packaging by pulling on the drinking straw, as a result of which an area of the drinking straw bends below, ie towards the inlet. The straw that protrudes from the beverage packaging, the kinked part and the latching nose form a T-shape that effectively prevents the straw from being pulled out.

The opening and thus also the latching lug in the various embodiments are preferably dimensioned such that the liquid outlet from the inside of the straw element through the opening does not adversely affect the functionality of the drinking straw. Accordingly, in the previously mentioned exemplary embodiments, the latching lug can still be connected to the stem wall on one side of the opening (the fourth side of the rectangle or trapezoid or the third side of the triangle). For example, an end region of the locking lug that points towards the outlet can additionally bend away, e.g. claw-like, from the longitudinal axis, while, for example, the rest of the latch does not include such a bend.

The at least one latching lug can be an element which is inserted and fastened into a section of the stalk wall. An acute angle can be included between the locking lug and the longitudinal axis. The cut in the straw wall can be transverse, for example perpendicular, to the longitudinal direction of the drinking straw, i.e. extend, for example, along a peripheral region of the stalk wall.

The element may comprise a first part which extends into an inner region of the stem element and a second part which extends outside of the stem element, wherein, for example, the first part can comprise a cutout which is designed to allow a liquid passage in the inner region of the stem element to enable. An acute angle can be included between the locking lug and the longitudinal axis. Because the latch extends into the inside of the straw element, the stability of the locking lug with respect to bending can be improved when trying to pull the straw out of the beverage packaging again.

The at least one latching lug can comprise a first part which can be fastened on the outer surface of the stalk wall and from which a second part of the latching lug can extend, which can be spaced from the outer surface of the stalk wall towards the outlet. An acute angle can be included between the locking lug and the longitudinal axis. The latch can be attached to the outer surface in a simple manner.

The first part can start at the inlet and extend from the inlet towards the outlet. For example, the first part can start at an insertion tip of the inlet.

The inlet may include an insertion tip.

The at least one locking lug can be produced using an injection molding process, for example separately from the straw element. The latching lug can then be fastened in a suitable manner to the straw element or inserted into it and then fastened, for example by means of a liquid-resistant adhesive, for example by means of clipping, welding or sealing. It can also be clipped on without using a liquid-resistant adhesive.

The drinking straw or the straw element can be manufactured using an injection molding process. The straw element and the locking lug or the locking lugs can thus be produced in one piece. The straw element and the locking lug or the locking lugs can also be produced separately. In the case of a separate production, the locking lug or the locking lugs can be at least partially connected to the stalk element by means of clipping on, welding on or sealing on.

A cross section of the stalk element can be round, oval, triangular or square.

A cross-sectional area of the insertion area and a cross-sectional area of the stem element, taking into account a wall thickness of the stem wall, can be similar, the cross-sectional area of the insertion area being 1% to 100%, (or also 30% to 70%) larger than the cross-sectional area of the stem element, taking into account the wall thickness of the stalk wall. Taking into account the wall thickness can mean that to the inner cross section the cross section of the wall element is added. In the case of a round inner cross section of the stem element, the wall cross section of a circular ring can have a ring width which corresponds to the wall thickness.

The insertion area can be surrounded by a reinforced area. In this way, entering the plug-in area can be protected from tearing when trying to pull the straw out of the beverage packaging.

The beverage packaging can be designed as a beverage carton, as a foil bag or as a stand-up pouch.

Figure 1A shows an oblique view from above of a beverage container 51, which is shown with the front side removed for the sake of clarity, so that the introduced straw 1 of a first embodiment (see also FIG Figure 1C ) is visible. On an upper side 52 of the beverage container 51, an insertion device 53 with a first cross-sectional area 54 is provided, into which the drinking straw 1 with a second cross-sectional area 7, also referred to as cross-section 7 for short, is introduced. The first cross-sectional area 54 is similar (in a mathematical sense) to the second cross-sectional area 7, ie the two cross-sectional areas 7, 54 have the same shape, but the first cross-sectional area 54 is larger than that second cross-sectional area 7. The first and the second cross-sectional area can also be of the same size.

In the first embodiment, the drinking straw 1 comprises a latching lug 2 and a tubular straw element 3, which comprises a straw wall 4, an inlet 5 to be placed in the beverage packaging and an outlet 6 to be placed outside the beverage packaging. In the illustration, the straw element 3 has a round cross section 7.

The insertion area 53 is surrounded by a reinforced area 55, which is designed here as a circular ring and extends from the insertion area over a ring width.

Figure 1B a schematic view of a film bag 64 with an inserted drinking straw 1 of the first embodiment (see also Figure 1C ). On a bag side 65, an insertion device 66 with a first cross-sectional area 67 is provided, into which the drinking straw 1 with a second cross-sectional area 7, also referred to as cross-section 7 for short, is introduced. The first cross-sectional area 67 is similar (in a mathematical sense) to the second cross-sectional area 7, ie the two cross-sectional areas 7, 67 have the same shape, but the first cross-sectional area 67 is larger than the second cross-sectional area 7. The insertion area 66 is surrounded by a reinforced area 68, which is designed here as a circular ring and extends from the insertion area over a ring width. However, the first and the second cross-sectional area can also be of the same size.

The Figure 1C shows a schematic oblique view of the first embodiment of the drinking straw 1 with a locking lug 2. The locking lug 2 was created by a three-sided cutout in the straw wall 4, so that the straw wall 4 has an opening 9 which corresponds in its dimensions to the locking lug 2. On one side 10 of the opening 9, the locking lug 2 is accordingly still connected to the stalk wall 4. The latching lug 2 can be regarded as a spread-apart part of the culm wall 4.

The locking lug 2 is provided on the outer surface of the stem wall 4. In the direction of the inlet 5, the locking lug 2 is connected to the outer surface of the culm wall 4, and in the direction of the outlet 6, an increasing spacing of the locking lug 2 from the outer surface of the culm wall 4 can be seen.

The latching lug 2 is at a distance d from the inlet 5 along a longitudinal axis 8 of the drinking straw 1 of at most 30% of a length l of the drinking straw 1. The drinking straw 1 shown comprises an insertion tip 11.

The Figure 1D shows a schematic oblique view from the front of a region of the insertion tip 11 of the drinking straw 1 and the Figure 1E shows a schematic view from behind of the area of the insertion tip 11 of the drinking straw 1.

In the Figure 1F it is shown how the catch 2 of the drinking straw 1 can deform when an attempt is made to remove the drinking straw 1 from the beverage packaging 51 again. If an attempt is made to pull the drinking straw 1 out of the beverage packaging 51 after the locking lug 2 has been introduced into the beverage packaging 51, the locking lug 2 interacts with the inner surface 56 of the beverage packaging 51 in an area around the insertion area 53 such that the locking lug 2 through the Pulling on the straw 1 is pressed against the inner surface 56, whereby its spacing from the outer surface of the straw wall 4 is partially increased. This partial enlargement of the spacing takes place where the locking lug 2 is not connected to the outer surface of the stem wall 4. The latching lug 2 can therefore spread apart from the outer surface of the straw wall 4 and thereby function like a barb and can prevent the drinking straw 1 from being pulled out of the beverage packaging 51 again.

In the Figure 1G it is shown how the catch 2 of the drinking straw 1 can deform when an attempt is made to remove the drinking straw 1 from the foil bag 64. If an attempt is made to pull the drinking straw 1 out of the film bag 64 after inserting the latch 2 into the film bag 64, the latch 2 interacts with the inner surface 69 of the film bag 64 in an area around the insertion area 66 in such a way that the latch 2 through the Pulling on the straw 1 is pressed against the inner surface 69, which partially increases its spacing from the outer surface of the straw wall 4. This partial enlargement of the spacing takes place where the locking lug 2 is not connected to the outer surface of the stem wall 4. The latching lug 2 can thus spread apart from the outer surface of the straw wall 4 and thereby function like a barb and can prevent the drinking straw 1 from being pulled out of the film bag 64 again. In general, the at least one latching lug of the different embodiments of the drinking straws should have a distance along the longitudinal axis of the drinking straw of at most 30% of a length of the drinking straw from the inlet.

In the Figure 2 this is shown schematically for a drinking straw 57, the inlet 58 of which has an insertion tip 59. Starting from the insertion tip 59 up to an outlet 60, the drinking straw 57 has a length l1. The area on a stalk wall 61, which extends on a lateral surface with a height of 0% of the length l1 up to 30% of the length l1, is shown hatched. For example, it can be provided that a level is the most extensive area of the latching nose which is distant from the inlet (for example an edge of the latching nose or a tip of the latching nose) and which is perpendicular to the longitudinal axis 62, cuts the drinking straw at a height h starting from the insertion tip 59 which is less than or equal to 30% of the length l1. Alternatively, it can be provided that a plane that passes through an area where the latching lug 63 begins to protrude from the outer surface of the stem wall 61 and that is perpendicular to the longitudinal axis 62 intersects the drinking straw at a height h1 starting from the insertion tip 59 that is less than or equal to 30% of length l1.

The Figure 3 shows a schematic oblique view of a second embodiment of a drinking straw 12 with two locking lugs 13. The drinking straw 12 is provided for a beverage packaging and comprises a tubular straw element 14, the straw wall 15, an inlet 16 to be placed in a beverage packaging and one to be placed outside the beverage packaging Outlet (not shown) includes. In the illustration, the straw element 14 has a round cross section 95 as an example.

The two locking lugs 13 are arranged opposite one another and each comprise a first part 17 which is fastened on the outer surface of the stem wall 15 and from which a second part 18 of the locking lug 13 extends, which has an increasing spacing in the direction of the outlet from the outer surface of the stem wall 15. The first part 17 extends from the inlet 16 towards the outlet and the second part 18 extends from an end of the first part 17 which is furthest away from the inlet 16 towards the outlet. The locking lugs 13 can thus be regarded as separate elements of the stem element 14, which are glued with the first parts 17, for example onto the stem wall 15, or are fastened in another liquid-resistant manner, for example by means of welding or sealing.

The Figure 4A shows a schematic view from the front of an area of a plug-in tip 20 of a third embodiment of a drinking straw 19 with a latching lug 21. The drinking straw 19 is provided for a beverage packaging and comprises a tubular straw element 22, a straw wall 23, an inlet to be placed in a beverage packaging 24 and an outlet to be placed outside the beverage packaging (not shown). In the illustration, the stalk element 22 has, for example, a round cross section 25.

The detent 21 comprises a first part 26 which is fastened on the outer surface of the stem wall 23 and from which a second part 27 of the detent 21 extends, which in the direction of the outlet has an increasing spacing from the outer surface of the stem wall 23 having. The first part 26 extends from the insertion tip 20 in the direction of the outlet and the second part 27 extends from one end of the first part 26, which is furthest away from the insertion tip 20, towards the outlet. The latching lug 21 can thus be regarded as separate elements of the straw element 22, which are glued with the first part 26, for example, to the straw wall 23 or fastened in another liquid-resistant manner, for example by means of welding or sealing.

The Figure 4B shows a schematic oblique view of the region of the insertion tip 20 of the drinking straw 19 of FIG Figure 4A .

The Figure 5 is a schematic oblique view of a fourth embodiment of a drinking straw 28 with two locking lugs 29. The drinking straw 28 is provided for a beverage packaging and comprises a tubular straw element 30, the stem wall 31, an inlet 32 to be placed in a beverage packaging and an outlet to be placed outside the beverage packaging (not shown). In the illustration, the straw element 30 has, for example, a round cross section 33 and an insertion tip 34.

The two locking lugs 29 are arranged opposite one another and each comprise a first part 35, which is arranged inside the stem element 30 and extends essentially up to the longitudinal axis 39, and a second part 36, which is arranged outside the stem element 30. The detent 29 is inserted through a cut 38 in the straw wall 31, which runs perpendicular to the longitudinal direction 39 of the drinking straw 28, with the first part 35 into the interior of the straw element 30 such that the first part 35 towards the inlet 32 and the second Part 36 points towards the outlet. An acute angle is enclosed between the locking lug 29 and the longitudinal axis 39. In the area around the cut 38, an adhesive can be provided which connects the latching lug 29 to the straw element 30

The first part 35 has, at the end facing the inlet 32, a recess 37, which is e.g. It is semicircular, that in spite of the two locking lugs 29 introduced into the straw element 30, a liquid can be transported through the interior of the straw element 30.

The Figure 6A shows a schematic oblique view of a fifth embodiment of a drinking straw 40 with two latching noses 41. The drinking straw 40 is provided for a beverage packaging and comprises a tubular straw element 42, a straw wall 43, an inlet 44 to be placed in a beverage packaging and one to be placed outside the beverage packaging Outlet (not shown) includes. In the illustration, the straw element 42 has, by way of example, a round cross section 45 and an insertion tip 46.

The two locking lugs 41 are arranged opposite one another and each comprise a first part 47 which is arranged in the interior of the stalk element 42 and does not extend to the longitudinal axis 48, but e.g. has a minimum distance from the longitudinal axis, which corresponds to half the radius of the drinking straw 40, and a second part 49, which is arranged outside the straw element 43. The detent 41 is inserted through a cut 50 in the straw wall 43, which runs perpendicular to the longitudinal direction 45 of the drinking straw 40, with the first part 47 into the interior of the straw element 42 such that the first part 47 towards the inlet 44 and the second Part 49 points towards the outlet. An acute angle is enclosed between the locking lug 41 and the longitudinal axis 45. In the area around the cut 50, an adhesive can be provided which connects the locking lug 41 to the stalk element 42.

Since the first two parts 47 are spaced apart from the longitudinal axis 45, liquid can be transported through the interior of the stem element 42.

In the Figure 6B shows how the two locking lugs 41 of the drinking straw 40 of the fifth embodiment can deform when an attempt is made to remove the drinking straw 40 again from a beverage packaging 51. If an attempt is made to pull the drinking straw 40 out of the beverage packaging 51 after the locking lugs 41 have been introduced into the beverage packaging 51, the locking lugs 41 each interact with the inner surface 56 of the beverage packaging 51 in an area around the insertion region 53 such that the locking lugs 41 pass through the pull on the drinking straw 40 is pressed against the inner surface 56, whereby the spacing of the second parts 49 of the latching lugs 41 from the outer surface of the straw wall 43 is partially increased. This partial enlargement of the spacing takes place where the second part 49 of the locking lugs 41 is not connected to the outer surface of the stalk wall 43. The locking lugs 41 can thus spread apart from the outer surface of the straw wall 43 and thereby function like barbs and can prevent the drinking straw 40 from being pulled out of the beverage packaging 51 again. The first parts 47 of the latching lugs 41, which are arranged in the interior of the straw element 42, can maintain their shape, ie their shape is not influenced by the interaction of the second parts 49 with the inner surface 56 of the beverage packaging 51.

In the Figure 6C it is shown how the two locking lugs 41 of the drinking straw 40 of the fifth embodiment can deform when an attempt is made to remove the drinking straw 40 again from a foil bag 64. If an attempt is made to pull the drinking straw 40 out of the film bag 64 after the latching lugs 41 have been introduced into the film bag 64, the latching lugs 41 each interact with the inner surface 69 of the film bag 64 in an area around the insertion region 66 such that the latching lugs 41 pass through pulling the straw 40 against the Inner surface 69 are pressed, whereby the spacing of the second parts 49 of the locking lugs 41 from the outer surface of the stalk wall 43 is partially increased. This partial enlargement of the spacing takes place where the second part 49 of the locking lugs 41 is not connected to the outer surface of the stalk wall 43. The locking lugs 41 can thus spread apart from the outer surface of the straw wall 43 and thereby function like barbs and can prevent the drinking straw 40 from being pulled out of the film bag 64 again. The first parts 47 of the latching lugs 41, which are arranged in the interior of the stem element 42, can maintain their shape, ie their shape is not influenced by the interaction of the second parts 49 with the inner surface 69 of the film bag 64.

Figure 7A shows a schematic oblique view of a sixth embodiment of a drinking straw 70 with a locking lug 76. The locking lug 76 was produced by a two-sided cutout in the straw wall 72, so that the straw wall 72 has an opening 77 which corresponds in its dimensions to the locking lug 76. The cut on both sides of the locking lug 76 can be produced by a cutting process in which a knife or a blade or another cutting tool cuts obliquely to a longitudinal axis of the drinking straw 70 into the drinking straw 70 and thereby cuts through the straw wall 72 on both sides of the locking lug. On one side of the opening 77, the locking lug 76 is accordingly still connected to the stalk wall 72. The locking lug 76 can be regarded as a spread-apart part of the culm wall 72. The latching nose 76 comprises a tip 78 which, for example, can additionally include a bend away from a longitudinal axis of the drinking straw, while, for example, the remaining region of the latching nose 76 does not comprise such a bend.

The detent 76 is provided on the outer surface of the stem wall 72. In the direction of the inlet 73, the locking lug 76 is connected to the outer surface of the culm wall 72, and in the direction of the outlet 75 an increasing spacing of the locking lug 76 from the outer surface of the culm wall 72 can be seen.

Such a latch 76, as in Figure 7A has the advantage that when the drinking straw is inserted into the beverage packaging, it can elastically deform inward toward the center of the drinking straw, so that the insertion process is not hindered. This results in particular from the fact that the shape of the opening 77 corresponds to the locking lug 76, so that the locking lug can be pressed elastically completely into the opening. As soon as the locking lug 76 is completely inside the beverage packaging, the locking lug can again elastically deform outwards.

The latching nose 76 is at a distance from the inlet 73 along a longitudinal axis of the drinking straw 70 of at most 30% of a length of the drinking straw 70. The drinking straw 70 shown comprises an insertion tip 79.

Figure 7B shows schematically how the latching nose 76 can deform when an attempt is made to remove the drinking straw 70 from a beverage packaging 51 again. If an attempt is made to pull the drinking straw 70 out of the beverage packaging 51 after the locking lug 76 has been introduced into the beverage packaging 51, the locking lug 76 interacts with the inner surface 56 of the beverage packaging 51 in an area around the insertion area 53 such that the locking lug 76 through the Pulling on straw 70 is pressed against inner surface 56, causing an area of drinking straw 70 below, ie toward inlet 73, to kink. The latching nose 76 can thus spread apart from the outer surface of the straw wall 72 and thereby function like a barb and can prevent the drinking straw 70 from being pulled out of the beverage packaging 51 again. The drinking straw 70 assumes a T-shaped shape, which prevents it from being pulled out very effectively, since the kinked part of the drinking straw and the latching nose come to rest on different sides of the insertion area on the inner surface 68 of the beverage packaging, while the rest of the drinking straw comes out of the Insert area and thus protrudes from the beverage packaging.

In Figure 7C shows how the catch 76 of the drinking straw 70 can deform when an attempt is made to remove the drinking straw 70 from the foil bag 64 again. If an attempt is made to pull the drinking straw 70 out of the film bag 64 after the latch 76 has been introduced into the film bag 64, the latch 76 interacts with the inner surface 69 of the film bag 64 in an area around the insertion area 66 such that the latch 76 through the Pulling on drinking straw 70 is pressed against inner surface 69, causing a region of drinking straw 70 to bend below, ie toward inlet 73. The latching nose 76 can thus spread apart from the outer surface of the straw wall 72 and thereby function like a barb and can prevent the drinking straw 70 from being pulled out of the film bag 64 again. Figure 8A schematically shows a tubular stalk element 80, on which a latching lug can be arranged. The straw element 80 comprises a straw wall 85, an inlet 83 to be placed in a beverage packaging with an inlet tip 84 and an outlet 81 to be placed outside the beverage packaging. The illustrated straw element 80 has a round cross section 82 with a diameter and a longitudinal axis 86. On this longitudinal axis 86 is also in the Figures 8B and 8D referenced to describe the locking lugs that can be arranged on the stalk element 80.

Figure 8B schematically shows a first embodiment of a locking lug 87 produced by means of an injection molding process. The locking lug 87 comprises a first part 88, which is designed here, for example, as an open ring surface, an inner diameter of the ring surface being equal to or up to 10% smaller than an outer diameter of the stem element 80, and a second part 89, which extends from the first part 88 away from the longitudinal axis 86. Due to the difference in diameter, the locking lug can be elastically clamped onto the surface of the stem element 80. However, the inside diameter of the ring surface can also be up to 1% or 5% larger than the outside diameter of the stem element, the latching nose then having to be connected to the drinking straw with additional measures such as welding, sealing or gluing. The first part 88 is designed such that it surrounds the circumference of the stem element 80 by more than half; it is possible to clip the catch 87 onto the stem element 80. The second part 89 is, for example, wing-like, but can also have other forms of a locking lug, such as any form of a barb. The wing-like embodiment has the advantage that when the drinking straw is inserted into the beverage packaging, it lies against the wall of the drinking straw and thus enables the drinking straw to be inserted easily into the beverage packaging.

Figure 8C shows a drinking straw 90, with the straw element 80 from FIG Figure 8A the locking lug 87 from the Figure 8B is arranged. The latching lug 87 can be clipped onto the stalk element by means of the first part 88. It is also possible to use a liquid-resistant adhesive. Then the catch 87 can alternatively also be welded or sealed onto the straw element 80. In other embodiments, more than one locking lug 87 can also be arranged on the straw element 80.

Figure 8D schematically shows a second embodiment of a locking lug 91 produced by means of an injection molding process. The locking lug 91 comprises a first part 92, which is intended to be arranged with the outer surface of the culm wall 85 by welding or sealing, for example using a liquid-resistant adhesive. In the illustration, the first part 92 is designed such that it surrounds the circumference of the stem element 80 by less than half; it is therefore not possible to clip this first part 92 onto the straw element 80. The detent 91 comprises a second part 93, which extends from the first part 92 and extends away from the longitudinal axis 86. The second part 93 is wing-shaped.

Figure 8E shows a drinking straw 94, with the straw element 80 from FIG Figure 8A the latch 91 from the Figure 8D is arranged. The first part 92 of the latching lug 91 can be connected to an outer surface of the culm wall 85 by welding or sealing.

In other embodiments, more than one latching lug 91 can also be arranged on the straw element 80. It is also possible to arrange one or more locking lugs 87 of the first embodiment and one or more locking lugs 91 of the second embodiment on a stalk element 80.

It also applies to the locking lugs produced by means of an injection molding process that they have a distance from the inlet 83 along the longitudinal axis 86 of the stem element 80 of at most 30% of a length of the stem element 80. The length of the straw element 80 and the length of a drinking straw which comprises the straw element 80 and one or more latching lugs correspond to one another, i.e. they are of the same size.
