Description

[0001] The invention relates to a method for closing a container containing fibers with a closure in a closure position, a container containing fibers which is closed with a closure in a closure position and a device for carrying out the method according to the independent claims. State of the art

[0002] WO 2022 / 096887 A1 discloses a two-part pulp bottle in which the head for attaching a closure is a separate component. The head must first be connected to the actual bottle in order to attach a closure after filling. Task

[0003] The object of the invention is to provide a method for closing a fiber-containing container with a closure in a closure position, a fiber-containing container which is closed with a closure in a closure position, and a device for carrying out the method, which can enable a secure closure of the fiber-containing container, for example without a weakening seam in the container, and a recyclability of the fiber-containing container. Solution

[0004] The problem is solved by the method for closing a fiber-containing container with a closure in a closing position, the fiber-containing container which is closed with a closure in a closing position, and the device for carrying out the method according to the independent claims. Further embodiments are disclosed in the dependent claims.

[0005] The inventive method for closing a fiber-containing container with a closure in a closure position comprises providing a fiber-containing container filled with product and comprising a neck region with an inner surface and an outer surface and with an opening. The method further comprises arranging a closure on the container. The closure comprises a cavity with a round cross-section for insertion into the opening and for being at least partially adjacent to the inner surface of the neck region, and an outer wall region spaced apart from the cavity for being at least partially adjacent to the outer surface of the neck region. The cavity is inserted into the opening and is thereby arranged at least partially adjacent to the inner surface of the neck region.In this process, the outer wall area, spaced away from the cavity, is positioned at least partially adjacent to the outer surface of the neck area. The method further comprises connecting the closure to the fiber-containing container to seal the container. This connection includes a form-fit, force-fit, and / or material-fit connection.

[0006] The fibers can include lignin, banana leaves, quinine, glass fibers, metal threads, and / or surgical sutures. For example, the fibers can be from conifers, deciduous trees, and / or plane trees, and / or from grasses, reeds, and / or bamboo, or the like. Lignin can provide structural support to the pulp and may also be suitable for transparent applications. Banana leaves may be suitable for larger containers, such as disposable tableware. Strength can be improved by embedding glass fibers, metal threads, and / or surgical sutures.

[0007] The fibers can include silk threads, spider silk, algae, natural fibers (such as cup plant fibers, hemp, corn, cotton), banana peels, orange peels, grass, straw, potato starch, or processed cow dung. Cellulose fibers produced through an artificial cultivation process can also be used. These alternative materials can completely or partially replace wood as the base material for a fluidized mass containing fibers in cases of material shortages.

[0008] Due to their natural origin, the fibers can be biodegradable. Furthermore, they can be sustainable and renewable.

[0009] The fibers can be used to produce a pulp, from which the fiber-containing containers can then be made, for example by forming them in a mold and for example by drying processes during or after forming.

[0010] The process may further include, prior to arranging the closure on the container, applying an adhesive to a first part of the inner surface and / or to a second part of the outer surface of the neck area and / or to a third part and / or to a fourth part of the closure. This may result in a material bond between the closure and the container.

[0011] The amount of adhesive applied to a second part of the outer surface of the neck area can be measured in such a way that a material-bonded connection is achieved by wetting the contacting surface areas of the outer surface of the neck area and the inner surface.

[0012] Alternatively, the amount of adhesive applied to the outer surface of the neck area can be such that it wets the contacting surface areas of the outer surface of the neck area and the inner surface, resulting in a material-bonded connection, and that it can also seal a boundary area between the outer surface of the neck area and an end area of ​​the inner surface.

[0013] The amount of adhesive applied to a first part of the inner surface of the neck area can be measured in such a way that no adhesive can come into contact with the product contained in the container.

[0014] The third part of the closure can include an area of ​​the wall to the cavity or the wall to the cavity.

[0015] The fourth part of the closure can encompass an area of ​​the outer wall or the outer wall area.

[0016] Connecting the closure to the container can further include inserting a circular cylindrical mandrel with a smooth outer surface into the cavity of the closure and positioning at least one pair of thread rollers and flanging rollers on an outer surface of the outer wall area of ​​the closure, followed by rolling and radially pressing the at least one pair of thread rollers and flanging rollers in the direction of the longitudinal axis of the container, thereby forming an external thread on the neck area of ​​the container and an external thread on the outer wall area of ​​the closure, and extracting the circular cylindrical mandrel from the cavity.

[0017] The outer surface can be the lateral surface of the circular cylindrical mandrel or encompass it.

[0018] "Smooth" in relation to the outer surface of the mandrel can, for example, mean profileless, such as without external threads.

[0019] The starting motion can be performed along a control curve.

[0020] Connecting the closure to the container can further include inserting a crimping head with an external thread into the cavity of the closure and positioning at least one crimping roller on an outer surface of the outer wall area of ​​the closure, then crimping and radially pressing the crimping roller in the direction of the longitudinal axis of the container, forming an external thread and an internal thread on the neck area of ​​the container, forming an external thread on the outer wall area of ​​the closure and an internal thread on the cavity of the closure, and unscrewing the crimping head from the cavity along the internal thread on the neck area.

[0021] The rolling head can have a round or substantially round cross-section. The rolling action can occur along a control curve.

[0022] Connecting the closure to the container can further include inserting and positioning a first flanging roller into and within the cavity of the closure, positioning a pair of threaded rollers and flanging rollers on an outer surface of the outer wall region of the closure, then rolling and radially pressing the first flanging roller away from a longitudinal axis of the container, and rolling and radially pressing the pair of threaded rollers and flanging rollers towards the longitudinal axis, thereby forming an external thread on the neck region and an internal thread on the neck region of the container, forming an external thread on the outer wall region of the closure and an internal thread on the cavity of the closure, and removing the first flanging roller from the cavity.

[0023] Furthermore, a fiber-containing container is provided, which is closed by a closure in a closed position. The closure comprises a cavity with a round cross-section and an outer wall region spaced apart from the cavity, wherein the cavity is inserted into an opening of the fiber-containing container and is arranged at least partially adjacent to an inner surface of a neck region of the fiber-containing container, and wherein the outer wall region spaced apart from the cavity is arranged at least partially adjacent to an outer surface of the neck region, and wherein the closure is connected to the container by a form-fit, force-fit, and / or material-fit connection.

[0024] The closure may contain metal, such as aluminum.

[0025] The closure may contain fibers. The information already provided above or below may apply to the fibers. The closure and the container may contain the same fibers or the same fiber mixture, or they may contain different fibers or different fiber mixtures.

[0026] The closure may include a locking ring. The locking ring may be designed to indicate, when intact, that the container has not yet been opened for the first time.

[0027] The closure may also or alternatively include a loss-proof mechanism, which allows it to be securely attached to the container.

[0028] An adhesive can be applied to a first part of the inner surface and / or to a second part of the outer surface of the neck area and / or to a third part and / or to a fourth part of the closure. This allows, as mentioned above, a material-bonded connection between the closure and the container to be achieved.

[0029] An external thread may be formed at the neck of the fiber-enclosing container, and an external thread may be formed on the outer wall of the closure.

[0030] This can be achieved, for example, in a closing process by inserting a circular cylindrical mandrel with a smooth outer surface into the cavity of the closure and positioning at least one pair of thread rollers and flanging rollers on an outer surface of the outer wall region of the closure, then rolling and radially pressing the at least one pair of thread rollers and flanging rollers in the direction of the longitudinal axis of the container, thereby forming an external thread on the neck region of the container and an external thread on the outer wall region of the closure and removing the circular cylindrical mandrel from the cavity.

[0031] An external thread and an internal thread may be formed at the neck area of ​​the fiber-enclosing container, and an external thread and an internal thread may be formed at the outer wall area of ​​the closure.

[0032] This can be achieved, for example, in a closing process by inserting a crimping head with an external thread into the cavity of the closure and positioning at least one crimping roller on an outer surface of the outer wall area of ​​the closure, then crimping and radially pressing the crimping roller in the direction of the longitudinal axis of the container, forming an external thread and an internal thread at the neck area of ​​the container, forming an external thread at the outer wall area of ​​the closure and an internal thread at the cavity of the closure, and unscrewing the crimping head from the cavity along the internal thread at the neck area.

[0033] An external thread and an internal thread may be formed at the neck area of ​​the fiber-enclosing container, and an external thread and an internal thread may be formed at the outer wall area of ​​the closure.

[0034] This can be achieved, for example, in a closing process by introducing and positioning a first flanging roller into and within the cavity of the closure, positioning a pair of threaded rollers and flanging rollers on an outer surface of the outer wall region of the closure, then rolling and radially pressing the first flanging roller away from a longitudinal axis of the container, and rolling and radially pressing the pair of threaded rollers and flanging rollers towards the longitudinal axis, thereby forming an external thread on the neck region and an internal thread on the neck region of the container, forming an external thread on the outer wall region of the closure and an internal thread on the cavity of the closure, and ejecting the first flanging roller from the cavity.

[0035] The container containing the fibers must have been sealed using one of the methods described above or below.

[0036] Furthermore, a device for carrying out the method as described above or below is provided. The device comprises a supply device for supplying a fiber-containing container filled with product, which includes a neck region with an inner surface and an outer surface and with an opening, and an arrangement device for arranging a closure on the fiber-containing container. The closure comprises a cavity with a circular cross-section for insertion into the opening and for arranging at least partially adjacent to the inner surface of the neck region, and an outer wall region spaced apart from the cavity for arranging at least partially adjacent to the outer surface of the neck region.The arrangement device is designed to insert the cavity into the opening, positioning it at least partially adjacent to the inner surface of the neck region, and to position the outer wall section, spaced apart from the cavity, at least partially adjacent to the outer surface of the neck region. The device further comprises a connecting device for positive-locking, force-locking, and / or material-locking connection of the closure to the fiber-containing container for sealing the fiber-containing container.

[0037] The device may further include an application device for applying an adhesive to a first part of the inner surface and / or to a second part of the outer surface of the neck area and / or to a third part and / or to a fourth part of the closure.

[0038] The device may further comprise a circular cylindrical mandrel with a smooth outer surface for insertion into and removal from the cavity of the closure, and at least one pair of thread rollers and flanging rollers for positioning on an outer surface of the outer wall region of the closure and for rolling and radially pressing in the direction of the longitudinal axis of the fiber-containing container, thereby forming an external thread on the neck region of the fiber-containing container and an external thread on the outer wall region of the closure.

[0039] The device can further comprise a rolling head with an external thread for insertion into the cavity of the closure and for unscrewing the rolling head from the cavity along an internal thread on the neck region of the fiber-containing container, and at least one flanging roller for positioning on an outer surface of the outer wall region of the closure and for rolling and radially pressing in the direction of the longitudinal axis of the fiber-containing container, thereby forming an external thread and an internal thread on the neck region of the fiber-containing container and forming an external thread on the outer wall region of the closure and an internal thread on the cavity of the closure.

[0040] The device can further comprise a first crimping roller for insertion into and positioning within the cavity of the closure and for removal from the cavity, and a pair of threaded rollers and crimping rollers for positioning on an outer surface of the outer wall region of the closure. The first crimping roller and the pair of threaded rollers and crimping rollers can be further configured to roll and radially press the first crimping roller away from a longitudinal axis of the fiber-containing container, and to roll and radially press the pair of threaded rollers and crimping rollers towards the longitudinal axis, thereby forming an external thread on the neck region and an internal thread on the neck region of the fiber-containing container, and to form an external thread on the outer wall region of the closure and an internal thread on the cavity of the closure.

Detailed character description

[0042] The Fig. Figure 1A shows a schematic oblique view of a closure 1. The closure 1 comprises a circular cylindrical outer wall region 2 having a first diameter D1. The outer wall region 2 is connected at its upper end to an annular wall region 3, which extends from the outer wall region 2 to a second diameter D2 that is smaller than the first diameter D2. From where the annular wall region 3 has the second diameter D2, it is connected to a circular cylindrical wall region 4 of a cavity 5 of the closure 1. The circular cylindrical wall region 4 has the second diameter D2 and is spaced apart from the circular cylindrical outer wall region 2. The space d1 can be determined by the difference between the first diameter D1 and the second diameter D2; the thickness of the closure 1 material can be taken into account here.The circular cylindrical wall area 4 is connected at a lower end to a circular base surface 6, which closes off the cavity 5 at the bottom.

[0043] The height H1 of the closure 1 can be dimensioned such that it is not greater than the height of a neck area of ​​a container that is to be closed with the closure.

[0044] Depending on the container, which may have different sized openings and / or different heights of neck areas, the dimensions of the closure can be designed accordingly.

[0045] The Fig. Figure 1B shows a schematic oblique view of a fiber-containing container 7. The container 7 includes a neck region 8 with a height H2, wherein the neck region 8 comprises an inner surface 9 and an outer surface 10. The neck region 8 includes at its upper end an opening 11, into which the closure 1 emerges from the Fig. 1A can be arranged and can be closed with the closure 1 when the closure 1 is in a closed position. The container 7 comprises a longitudinal axis 12.

[0046] The Fig. Figure 2 shows a cross-section of the closure 1 inserted into the opening 11 of the container 7.

[0047] By inserting the closure 1 into the opening 11, the cavity 5 is inserted into the opening 11 and is thereby arranged at least partially adjacent to the inner surface 9 of the neck region 8, and the outer wall region 2, which is spaced apart from the cavity 5, is arranged at least partially adjacent to the outer surface 10 of the neck region 8.

[0048] For example, a material-bonded connection of the closure 1 to the container 7 can be achieved if, before the closure 1 is inserted into the opening 11, an adhesive is applied to a first part of the inner surface 9 and / or to a second part of the outer surface 10 of the neck region 8 and / or to a third part and / or to a fourth part of the closure 1. The third part can comprise the wall portion of the outer wall region 2 that can come into contact with the outer surface 10 of the neck region 8. The fourth part can comprise the wall portion of the circular cylindrical wall region 4 of the cavity 5 that can come into contact with the inner surface 9 of the neck region 8.

[0049] The Fig. Figure 3A shows a cross-section of a first embodiment for closing the container 7 with the closure 1 in a closed position. The cavity 5 of the closure 1, which is placed on the container 7 (as, for example, in the Fig. 2 described; where adhesive may or may not be used) a circular cylindrical mandrel 13 with a smooth outer surface 14 is inserted. A pair of thread roller 15 and flanging roller 16 is positioned on an outer surface of the outer wall region 2 of the closure 1.

[0050] By rolling and radially pressing the pair of thread rollers 15 and flanging rollers 16 in the direction of the longitudinal axis 12 of the container 7, an external thread can be formed on the neck region 8 of the container 7 and an external thread on the outer wall region 2 of the closure 1. The rolling can be carried out by rotating about a rotation axis 17 and moving along a control cam.

[0051] Afterwards, the circular cylindrical mandrel 13 can be removed from the cavity 5 and the pair of thread roller 15 and flanging roller 16 can be removed from the outer surface of the outer wall area 2.

[0052] The Fig. Figure 3B shows a cross-section through a formed external thread 18 at the neck area 8 of the container 7 and a formed external thread 19 at the outer wall area 2 of the closure 1.

[0053] The Fig. Figure 4A shows a cross-section of a second embodiment for closing the container 7 with the closure 1 in a closed position. The cavity 5 of the closure 1, which is placed on the container 7 (as, for example, in the Fig. 2 described; where adhesive may or may not be used) a crimping head 20 with an external thread 21 is inserted. Two crimping rollers 22 are positioned on the outer surface of the outer wall area 2 of the closure 1.

[0054] By rolling and radially pressing the two flanging rollers 22 in the direction of the longitudinal axis 12 of the container 7, an external thread and an internal thread can be formed on the neck region 8 of the container 7, an external thread on the outer wall region 2 of the closure 1, and an internal thread on the cavity 5 of the closure 1. The rolling action can be performed by rotating about a respective axis of rotation 23 and moving along a control cam.

[0055] Afterwards, the crimping head 20 can be unscrewed from the cavity 5 along the internal thread on the cavity 5 and the two crimping rollers 22 can be removed from the outer surface of the outer wall area 2 of the closure 1.

[0056] The Fig. Figure 4B shows a cross-section through a formed external thread 24 and a formed internal thread 25 at the neck region 8 of the container 7 and a formed external thread 26 at the outer wall region 2 of the closure 1 and a formed internal thread 27 at the cavity 5 of the closure 1.

[0057] The Fig. Figure 5A shows a cross-section of a third embodiment for closing the container 7 with the closure 1 in a closed position. The cavity 5 of the closure 1, which is placed on the container 7 (as, for example, in the Fig. 2 described (where adhesive may or may not be used) a first flanging roller 28 is inserted and positioned. A pair of threaded roller 29 and flanging roller 30 is positioned on the outer surface of the outer wall area 2 of the closure 1.

[0058] By rolling and radially pressing the first flanging roller 28 away from the longitudinal axis 12 of the container 7, and by rolling and radially pressing the pair of threaded roller 29 and flanging roller 30 towards the longitudinal axis 12, an external thread can be formed on the neck region 8 and an internal thread on the neck region 8 of the container 7, as well as an external thread on the outer wall region 2 of the closure 1 and an internal thread on the cavity 5 of the closure 1. The rolling can be carried out by rotating the first flanging roller 28 about a rotation axis 31 and moving it along a control cam, and by rotating the pair of threaded roller 29 and flanging roller 30 about a rotation axis 32 and moving them along a control cam.

[0059] Afterwards, the first flanging roller 28 can be removed from the cavity 5 and the pair of thread roller 29 and flanging roller 29 can be removed from the outer surface of the outer wall area 2.

[0060] The Fig.Figure 5B shows a cross-section through a formed external thread 33 and a formed internal thread 34 at the neck region 8 of the container 7 and a formed external thread 35 at the outer wall region 2 of the closure 1 and a formed internal thread 36 at the cavity 5 of the closure 1.
