Alternatively, the removal device may include a sleeve tube with two stopper webs at the end of the sleeve facing the bag end, wherein a ring is formed near the stopper web and above the stopper web, and A handle web extending in the axial direction is scattered along the circumferential direction above the ring. purpose

Therefore, the object of the present invention is to provide a drinking straw and a beverage package, which enables the drinking straw to be retained in the beverage package. The solution

This purpose is solved by the beverage packaging as in claim 1. Preferred specific examples and further developments are disclosed in the attached claims.

A beverage package for containing liquid products includes an insertion area for inserting a drinking straw and the drinking straw. The drinking straw includes a tubular straw member, which includes a straw wall, an inlet placed in the beverage package, and an outlet placed outside the beverage package. The outer surface of the straw wall is provided with at least one locking member, which is connected to the outer surface of the straw wall toward the inlet and is spaced apart from the outer surface of the straw wall toward the outlet. The distance between the at least one locking member and the entrance along the longitudinal axis of the drinking straw is at most 30% of the length of the drinking straw.

Providing at least one locking member at the lower part of the drinking straw can prevent the drinking straw from being lost after being placed in the beverage package, but the drinking straw can still move up and down within a relatively large range to facilitate the removal of the liquid.

An acute angle can be sandwiched between the locking member and the longitudinal axis.

The at least one locking element can be arranged such that when the drinking straw passes through the insertion area and is inserted into the beverage package through the insertion area, the at least one locking element can be reversibly pressed against the straw wall, that is, the drinking straw Straw components. When passing through the insertion area, there is no or almost no distance between the at least one locking member and the outer surface of the straw wall.

After the at least one locking member passes through the insertion area, that is, completely inside the beverage package, the at least one locking member can return to its original position relative to the outer surface of the straw wall.

If an attempt is made to pull the drinking straw out of the beverage package after inserting the at least one locking element into the beverage package, the at least one locking element can be in contact with the inside of the beverage package in the area around the insertion area. The surface interacts so that it can be pressed against the inner surface by pulling the drinking straw. For example, the distance from the outer surface of the straw wall can be partially increased or kept constant. The at least one locking member can act like a barb and prevent the drinking straw from being pulled out of the beverage package again.

The at least one locking member can be an expanded portion of the straw wall. The locking member can be manufactured by a three-sided cut-out of the straw wall, so that the straw wall can have an opening corresponding to the locking member in size; for example, if the lock The surface of the tight element is expanded into a flat surface, and its shape can be rectangular or trapezoidal. Alternatively, the locking member can be manufactured by performing a two-sided cut in the straw wall, for example, by placing the cutting device at an angle relative to the straw wall, such as The longitudinal axis is at an acute angle, and the straw wall is cut in the direction of the entrance. Then, for example, if the surface of the locking member is expanded into a flat surface, the surface may be triangular. If you try to pull the drinking straw out of the beverage package after the locking members cut on both sides of the straw wall are inserted into the beverage package, the locking member may be in contact with the area around the insertion area on the inner surface of the beverage package. The interaction causes the locking member to press against the inner surface of the beverage package by the pulling of the drinking straw, thereby twisting the area below the drinking straw (that is, toward the entrance). The drinking straw protruding from the beverage package, the kinked part and the locking member form a T shape that can effectively prevent the drinking straw from being pulled out.

Preferably, in each specific example, the size of the opening and therefore the locking member is designed such that the liquid outlet from the inside of the straw member through the opening does not negatively affect the function of the drinking straw. In the above specific example, the locking member may be connected to the straw wall on one side of the opening (the fourth side of the rectangle or trapezoid or the third side of the triangle). For example, the end of the locking member pointing to the outlet may additionally include a curved portion away from the longitudinal axis, such as a claw-like, while the remaining part of the locking member does not include this curved portion, for example.

The at least one locking member can be an element inserted and fixed in the cutout of the straw wall. An acute angle can be sandwiched between the locking member and the longitudinal axis. The cut in the wall of the straw may extend across, for example perpendicular to, the longitudinal extension of the drinking straw, that is, for example, extend along the circumferential area of the straw wall.

The element may include a first portion extending into the inner region of the straw member and a second portion extending to the outside of the straw member, for example, the first portion may include a cutout suitable for passing liquid through the inner region of the straw member (cut-out). An acute angle can be sandwiched between the locking member and the longitudinal axis. When trying to pull the drinking straw out of the beverage package again, the fact that the locking member extends into the inside of the straw member improves the stability of the locking member in terms of bending.

The at least one locking member may include a first part that can be fastened to the outer surface of the straw wall, and a second part of the locking member that can extend from the first part, and the second part can be connected to the outer surface of the straw wall. The surface is spaced towards the outlet. An acute angle can be sandwiched between the locking member and the longitudinal axis. The locking member can be fixed to the outer surface in a simple manner.

The first part may start from the inlet and extend from the inlet to the outlet. For example, the first part may start from the insertion tip of the inlet.

The inlet may include an insertion tip.

The at least one locking member can be manufactured by injection molding, for example, manufactured separately from the straw member. The locking member can then be fixed to the straw member in a suitable manner, or inserted into it and then fixed with a liquid-resistant adhesive, for example, by clamping, welding or sealing. It can also be clamped without using liquid-resistant adhesives.

The drinking straw or straw member can be manufactured by injection molding. Therefore, the straw member and the locking member can be made into one piece. The straw member and the locking member can also be manufactured separately. In the case of separate manufacture, the locking member can be at least partially connected to the straw member by clamping, welding or sealing.

The cross section of the straw member can be circular, oval, triangular or square.

Considering the wall thickness of the straw wall, the cross-sectional area of the insertion area and the cross-sectional area of the straw member can be similar. Considering the wall thickness of the straw wall, the cross-sectional area of the insertion area is larger than the cross-sectional area of the straw member. The area is 1% to 100% larger (or even 30% to 70%). Considering the wall thickness may mean adding the wall cross section to the inner cross section of the straw member. In the case where the internal cross section of the straw member is circular, the wall cross section of the circular ring may have a ring width corresponding to the wall thickness.

The insertion area can be surrounded by a reinforced part. Therefore, when trying to pull the drinking straw out of the beverage package again, tearing into the insertion area can be prevented.

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

Figure 1A shows an oblique view of the beverage container 51 from above, showing the front part removed for clarity, so that the inserted drinking straw 1 of the first specific example can be seen (see also Figure 1C). An insertion device 53 having a first cross-sectional area 54 is arranged on the upper side 52 of the beverage container 51, and a drinking straw 1 having a second cross-sectional area 7, also referred to as a cross-section 7 for short, is inserted into the insertion device 53. The first cross-sectional area 54 is similar to the second cross-sectional area 7 (in a mathematical sense), that is, the two cross-sectional areas 7, 54 have the same shape, but the first cross-sectional area 54 is larger than the second cross-sectional area. Sectional area 7. However, the first and second cross-sectional areas may also have the same size.

In the first specific example, the drinking straw 1 includes the locking member 2 and a tubular straw member 3, and the tubular straw member 3 includes the straw wall 4, the inlet 5 placed in the beverage package, and the beverage package Outer exit 6. In this illustration, the straw member 3 has a circular cross section 7.

The insertion area 53 is surrounded by a reinforcement 55 which is here designed as an annular ring and extends from the insertion area over the width of the ring.

Fig. 1B shows a schematic diagram of the foil bag 64 with the drinking straw 1 inserted in the first specific example (see also Fig. 1C). On one side of the bag 65 is an insertion device 66 having a first cross-sectional area 67, and a drinking straw 1 having a second cross-sectional area 7, also referred to as cross-section 7 for short, is inserted into the first cross-sectional area 67 . The first cross-sectional area 67 (in a mathematical sense) is similar to the second cross-sectional area 7, that is, the two cross-sectional areas 7, 67 have the same shape, wherein the first cross-sectional area 67 is larger than the second cross-sectional area 7. The insertion area 66 is surrounded by a reinforcement area 68 which is formed here as a ring and extends from the insertion area over the width of the ring. However, the first and second cross-sectional areas may also have the same size.

FIG. 1C shows a schematic oblique view of the first specific example of the drinking straw 1 with the locking member 2. The locking member 2 is formed by three-sided cuts in the straw wall 4, so the straw wall 4 has an opening 9 with a size corresponding to the locking member 2. On one side 10 of the opening 9, the locking member 2 is still connected to the straw wall 4. The locking member 2 can be regarded as the unfolded part of the straw wall 4.

The locking member 2 is arranged on the outer surface of the straw wall 4. In the direction of the inlet 5, the locking member 2 is connected to the outer surface of the straw wall 4, and in the direction of the outlet 6, the distance between the locking member 2 and the outer surface of the straw wall 4 gradually increases.

The distance d between the locking member 2 along the longitudinal axis 8 of the drinking straw 1 and the inlet 5 is at most 30% of the length l of the drinking straw 1. The drinking straw 1 shown includes an insertion tip 11.

FIG. 1D shows a schematic oblique view from the front of a part of the insertion tip 11 of the drinking straw 1, and FIG. 1E shows a schematic oblique view from the back of a part of the insertion tip 11 of the drinking straw 1.

Figure 1F shows how the locking member 2 of the drinking straw 1 is deformed if one tries to take out the drinking straw 1 from the beverage package 51. If an attempt is made to pull the drinking straw 1 out of the beverage package 51 after the locking member 2 is inserted into the beverage package 51, the locking member 2 and the inner surface 56 of the beverage package 51 are in the area surrounding the insertion area 53 The interaction between the locking member 2 is caused by pulling the drinking straw 1 to press against the inner surface 56 so that the distance between the locking member 2 and the outer surface of the straw wall 4 is locally increased. This local increase in the distance occurs when the locking member 2 is not connected to the outer surface of the straw wall 4. The locking member 2 can therefore expand from the outer surface of the straw wall 4 and act like a barb and can prevent the drinking straw 1 from being pulled out of the beverage package 51 again.

Figure 1G shows how the locking member 2 of the drinking straw 1 deforms when trying to take out the drinking straw 1 from the foil bag 64. If one tries to pull the drinking straw 1 out of the foil bag 64 after the locking member 2 has been inserted into the foil bag 64, the locking member 2 and the inner surface 69 of the foil bag 64 are in the area surrounding the insertion area 66 In this way, the locking member 2 is pressed against the inner surface 69 by pulling the drinking straw 1 so that the distance between it and the outer surface of the straw wall 4 is locally increased. This local increase in the distance occurs when the locking member 2 is not connected to the outer surface of the straw wall 4. The locking member 2 can therefore expand from the outer surface of the straw wall 4 and act like a barb and can prevent the drinking straw 1 from being pulled out of the foil bag 64 again. Generally, the distance between at least one locking member in different specific examples of drinking straws and the inlet along the longitudinal axis of the drinking straw is at most 30% of the length of the drinking straw.

FIG. 2 schematically shows a drinking straw 57 whose inlet 58 has an insertion tip 59. From the insertion tip 59 to the outlet 60, the drinking straw 57 has a length l1. The designated area on the straw wall 61 is shaded and the height extending on the side surface is 0% of the length l1 to 30% of the length l1. For example, it may be specified that a plane passing through the region of the locking member farthest from the entrance and perpendicular to the longitudinal axis 62 (for example, the edge of the locking member or the tip of the locking member), at a distance from the insertion tip 59 Cut the drinking straw at the height h of, and the height h is less than or equal to 30% of the length l1. Alternatively, it may be provided that the plane of the area passing through the locking member 63 that starts to protrude from the outer surface of the straw wall 61 and is perpendicular to the longitudinal axis 62 meets the drinking straw at a height h1 from the insertion tip 59, the The height h1 is less than or equal to 30% of the length l1.

FIG. 3 shows a schematic oblique view of a second specific example of the drinking straw 12 with two locking members 13. The drinking straw 12 is for the beverage package, and includes a tubular straw member 14 that includes a straw wall 15, an inlet 16 placed in the beverage package, and an outlet (not shown) placed outside the beverage package . In this illustration, the straw member 14 exemplarily has a circular cross section 95.

The two locking members 13 are arranged opposite to each other and each includes a first portion 17 fixed to the outer surface of the straw wall 15, and a second portion 18 of the locking member 13 extends from the first portion 17, the second portion The distance between 18 and the outer surface of the straw wall 15 gradually increases toward the outlet. The first portion 17 extends from the inlet 16 to the outlet, and the second portion 18 extends from the end of the first portion 17 farthest from the inlet 16 to the outlet. The locking member 13 can therefore be regarded as an independent element of the straw member 14, which is, for example, adhered to the straw wall 15 by the first part 17 or fixed in another liquid-resistant manner, for example, Welding or sealing.

4A shows a schematic view of the area where the tip 20 is inserted into the third specific example of the drinking straw 19 with the locking member 21 viewed from the front. The drinking straw 19 is for the beverage package and includes a tubular straw member 22 that includes: a straw wall 23, an inlet 24 placed in the beverage package, and an outlet (not shown) placed outside the beverage package . In this illustration, the straw member 22 exemplarily has a circular cross section 25.

The locking member 21 includes a first portion 26 attached to the outer surface of the straw wall 23, and a second portion 27 of the locking member 21 extends from the first portion 26, and the second portion 27 is connected to the straw wall 23 The distance of the outer surface increases toward the outlet. The first portion 26 extends from the insertion tip 20 to the outlet, and the second portion 27 extends from the end of the first portion 26 farthest from the insertion tip 20 to the outlet. Therefore, the locking member 21 can be regarded as an independent component of the straw member 22, for example, the first part 26 is bonded to the straw wall 23, or fixed in another liquid-resistant manner, for example, By welding or sealing.

Fig. 4B shows a schematic oblique view of the area where the tip 20 of the drinking straw 19 of Fig. 4A is inserted.

FIG. 5 shows a schematic oblique view of a fourth specific example of the drinking straw 28 with two locking members 29. The drinking straw 28 is for the beverage package and includes a tubular straw member 30 that includes a straw wall 31, an inlet 32 placed in the beverage package, and an outlet (not shown) placed outside the beverage package . In this illustration, the straw member 30 has an exemplary circular cross section 33 and an insertion tip 34.

The two locking members 29 are arranged opposite to each other and each includes a first part 35 arranged inside the straw member 30 and substantially extending to the longitudinal axis 39 and a second part 36 arranged outside the straw member 30. The locking member 29 is inserted into the inside of the straw member 30 with the first part 35 through the slit 38 in the straw wall 31. The direction of the slit 38 is perpendicular to the longitudinal axis 39 of the drinking straw 28, so that the first part 35 points to the The inlet 32 and the second portion 36 point toward the outlet. An acute angle is formed between the locking member 29 and the longitudinal axis 39. In the area around the cut 38, an adhesive can be applied to connect the locking member 29 to the straw member 30.

The first part 35 has a semicircular recess 37 at the end facing the inlet 32. Although the two locking members 29 are inserted into the straw member 30, liquid can still pass through the straw member 30. Internal transmission.

FIG. 6A shows a schematic oblique view of a fifth specific example of a drinking straw 40 with two locking members 41. The drinking straw 40 is used for beverage packaging and includes a tubular straw member 42 including a straw wall 43, an inlet 44 placed in the beverage package, and an outlet (not shown) placed outside the beverage package. In this illustration, the straw member 42 exemplarily has a circular cross section 45 and an insertion tip 46.

The two locking members 41 are arranged opposite to each other and each includes a first part 47, which is arranged inside the straw member 42 and does not extend to the longitudinal axis 48, but for example, the longitudinal axis has the equivalent of the drinking The minimum distance of half the radius of the straw 40; and the second portion 49, which is arranged outside the straw member 43. The locking member 41 is inserted into the inside of the straw member 42 with the first part 47 through the slit 50 in the straw wall 43, and the direction of the slit 50 is perpendicular to the longitudinal direction 45 of the drinking straw 40, so that the first part 47 points toward the entrance 44 and the second part 49 points to the exit. An acute angle is sandwiched between the locking member 41 and the longitudinal axis 45. In the area around the cut 50, an adhesive can be applied to connect the locking member 41 with the straw member 42.

Since the first two parts 47 are separated from the longitudinal axis 45, liquid can be conveyed through the inside of the straw member 42.

6B shows how the two locking members 41 of the drinking straw 40 of the fifth specific example can be deformed if one tries to take the drinking straw 40 out of the beverage package 51. If an attempt is made to pull the drinking straw 40 out of the beverage package 51 after the locking member 41 is inserted into the beverage package 51, the locking member 41 and the inner surface 56 of the beverage package 51 are positioned around the insertion area 53 respectively. The interaction in the region causes the locking member 41 to press against the inner surface 56 by pulling the drinking straw 40, so that the distance between the second part 49 of the locking member 41 and the outer surface of the straw wall 43 is partially Enlarged. This local increase in the distance occurs when the second part 49 of the locking member 41 is not connected to the outer surface of the straw wall 43. The locking member 41 can therefore expand from the outer surface of the straw wall 43 and act like a barb and can prevent the drinking straw 40 from being pulled out of the beverage package 51 again. The first part 47 of the locking member 41 arranged inside the straw member 42 can maintain its shape, that is, its shape is not affected by the interaction between the second part 49 and the inner surface 56 of the beverage package 51.

6C shows how the two locking members 41 of the drinking straw 40 of the fifth specific example can be deformed if one tries to take out the drinking straw 40 from the foil bag 64. If an attempt is made to pull the drinking straw 40 out of the foil bag 64 after the locking member 41 is inserted into the foil bag 64, the locking member 41 and the inner surface 69 of the foil bag 64 are in a position surrounding the insertion area 66. The interaction in the region causes the locking member 41 to press against the inner surface 69 by pulling the drinking straw 40, so that the distance between the second part 49 of the locking member 41 and the outer surface of the straw wall 43 is locally Enlarged. This local increase in the distance occurs when the second part 49 of the locking member 41 is not connected to the outer surface of the straw wall 43. Therefore, the locking member 41 can expand from the outer surface of the straw wall 43 and thereby function like a barb and can prevent the drinking straw 40 from being pulled out of the beverage package 51 again. The first part 47 of the locking member 41 arranged inside the straw member 42 can maintain its shape, that is, its shape is not affected by the interaction between the second part 49 and the inner surface 69 of the foil bag 64.

FIG. 7A shows a schematic oblique view of a sixth specific example of the drinking straw 70 with the locking member 76. The locking member 76 is made by cutting two sides of the straw wall 72, so the straw wall 72 has an opening 77 with a size corresponding to the locking member 76. The incisions on both sides of the locking member 76 can be completed by a cutting process, wherein a knife or blade or other cutting tool is obliquely cut into the drinking straw 70 relative to the longitudinal axis of the drinking straw 70, and cuts through the two locking members. Side of the straw wall 72. On one side of the opening 77, the locking member 76 is still connected to the straw wall 72. The locking member 76 can be regarded as an expanded portion of the straw wall 72. The locking member 76 includes a tip 78. The tip 78 may additionally include a bent portion away from the longitudinal axis of the drinking straw, and for example, the rest of the locking member 76 does not include this bent portion.

The locking member 76 is arranged on the outer surface of the straw wall 72. Toward the inlet 73, the locking member 76 is connected to the outer surface of the straw wall 72, and toward the outlet 75, it can be seen that the distance between the locking member 76 and the outer surface of the straw wall 72 gradually increases.

The advantage of the locking member 76 shown in FIG. 7A is that when the drinking straw is inserted into the beverage package, it can be elastically deformed inward according to the central direction of the drinking straw, so the insertion process is not hindered. This is particularly due to the fact that the opening 77 corresponds in shape to the locking member 76, so that the locking member can be completely elastically pressed into the opening. Once the locking member 76 is completely inside the beverage package, the locking member can be elastically deformed outward again.

The distance between the locking member 76 and the inlet 73 along the longitudinal axis of the drinking straw 70 is at most 30% of the length of the drinking straw 70. The drinking straw 70 shown includes an insertion tip 79.

FIG. 7B schematically shows how the two locking members 76 can be deformed when trying to take the drinking straw 70 out of the beverage package 51. If an attempt is made to remove the drinking straw 70 from the beverage package 51 after the locking member 76 is inserted into the beverage package 51, the locking member 76 and the inner surface 56 of the beverage package 51 are in the area surrounding the insertion area 53 The interaction causes the locking member 76 to press against the inner surface 56 by pulling the drinking straw 70, thereby twisting the area below the drinking straw 70 (that is, toward the entrance). The locking member 76 can therefore expand from the outer surface of the straw wall 72 and act like a barb and can prevent the drinking straw 70 from being pulled out of the beverage package 51 again. The drinking straw 70 is T-shaped, which effectively prevents the drinking straw from being pulled out, because the bent portion of the drinking straw and the locking member are stuck on the inner surface of different sides of the insertion area of the beverage package, and the rest of the drinking straw The straw protrudes from the insertion area, thereby protruding from the beverage package.

FIG. 7C shows how the locking member 76 of the drinking straw 70 can be deformed when trying to take out the drinking straw 70 from the foil bag 64. If an attempt is made to pull the drinking straw 70 out of the foil bag 64 after the locking member 76 is inserted into the foil bag 64, the locking member 76 and the inner surface 69 of the foil bag 64 are in the area surrounding the insertion area 66 The middle interaction causes the locking member 76 to press against the inner surface 69 by pulling the drinking straw 70, thereby bending the area below the drinking straw 70 (that is, toward the entrance 73). Therefore, the locking member 76 can expand from the outer surface of the straw wall 72 and act like a barb and can prevent the straw 70 from being pulled out of the foil bag 64 again. Fig. 8A schematically shows the tubular straw member 80 on which the locking member can be arranged. The straw member 80 includes a straw wall 85, an inlet 83 placed in the beverage package and having an inlet tip 84, and an outlet 81 placed outside the beverage package. The illustrated straw member 80 has a circular cross section 82 with a diameter and a longitudinal axis 86. The longitudinal axis 86 is also cited in FIGS. 8B and 8D in order to describe the locking member that can be arranged on the straw member 80.

FIG. 8B schematically shows a first specific example of the locking member 87 by injection molding. The locking member 87 includes a first portion 88 formed here as an example of an open annular surface, the inner diameter of the annular surface is smaller than the outer diameter of the straw member 80 by 10% or at most 10%; and from the first portion 88 The second portion 89 extends away from the longitudinal axis 86. Due to the difference in diameter, the locking member can be elastically clamped on the surface of the drinking straw 80. The inner diameter of the annular surface can also be at most 1% or 5% larger than the outer diameter of the straw member, so that other means (such as welding, sealing or gluing) must then be used to connect the locking member to the drinking straw. The first part 88 is designed such that it surrounds more than half of the circumference of the straw member 80; in this way, the locking member 87 can be clamped on the straw member 80. The second part 89 is wing-shaped, for example, but can also have other forms of locking elements, such as any form of barbs. The advantage of the wing-shaped design is that when the drinking straw is inserted into the beverage package, the drinking straw is placed against the wall of the drinking straw, so that the drinking straw is easily inserted into the beverage package.

Fig. 8C shows a drinking straw 90 in which the locking member 87 of Fig. 8B is arranged on the straw member 80 of Fig. 8A. The first part 88 can be used to clamp the locking member 87 on the drinking straw assembly. Liquid-resistant adhesives can also be used. Then, the locking member 87 can be welded or sealed to the straw member 80 selectively. In other specific examples, more than one locking member 87 may also be arranged on the straw member 80.

FIG. 8D schematically shows a second specific example of the locking member 91 by injection molding. The locking member 91 includes a first portion 92 configured to be used, for example, a liquid-resistant adhesive welded or sealed on the outer surface of the straw wall 85. In this illustration, the first part 92 is designed such that it surrounds less than half of the circumference of the straw member 80; therefore, the first part 92 cannot be clamped on the straw member 80. The locking member 91 includes a second portion 93 extending away from the longitudinal axis 86 from the first portion 92. The second part 93 is wing-shaped.

Fig. 8E shows the drinking straw 94, in which the locking member 91 of Fig. 8D is arranged on the straw member 80 of Fig. 8A. The first part 92 of the locking member 91 can be connected to the outer surface of the straw wall 85 by welding or sealing.

In other specific examples, more than one locking member 91 can also be arranged on the straw member 80. One or more locking members 87 of the first embodiment and one or more locking members 91 of the second embodiment can also be arranged on the straw member 80.
