Description

Background of the invention

[0001] The invention relates to a connection system comprising a first adhesive element, which has a plurality of adhesive elements, and a carrier element, wherein the first adhesive element has a first free end and is pivotably arranged or formed on the carrier element at a connection area spaced apart from the first free end, wherein a first pivotable part of the first adhesive element has a length L from the first free end of the first adhesive element to the beginning of the connection area. The invention also relates to a hygiene article and a method for releasing an adhesive connection.

[0002] Adhesive bonding systems, particularly manually releasable bonds, often feature flat adhesives with numerous adhesive elements that can be intuitively handled by a user, even a small child. To release such a bond, the user typically grasps a free end of one of the adhesives and peels it away from the other. The user will intuitively choose this peeling method, as the force required is largely determined by the width of the peeling front. The force required is considerably less than if the user were to attempt to separate the adhesives by pushing or lifting them vertically, in which case the force required is largely determined by the surface area of ​​the bonded areas.It follows that the release of a corresponding adhesive bond usually occurs by disposing of a free end of one of the adhesives or of a carrier element connected to one of the adhesives in the direction of the (still) adhering areas of the adhesives.

[0003] The generic patent EP 2 244 599 B1 describes a detachable fastening arrangement, for example in the form of a hook-and-loop fastener, wherein a flexible flap is formed within an adhesive. The flexible flap, as well as the areas surrounding the flap, carries adhesive elements and can pivot out of the plane of the adhesive. When the adhesive bond is separated by peeling, whereby a peeling front moves in one direction from a free end of the flap to an attached end of the same, the flap initially remains adhered while being traversed by the peeling front. Subsequently, a tensile force is exerted on the flap due to the attached end, but it is not peeled off the corresponding adhesive, but rather pulled off.The resulting peel resistance of the entire fastening assembly, and thus the force required to release the corresponding adhesive bond, can therefore be adjusted based on the design of the flap. In particular, the resulting peel resistance can be increased and / or discrete discontinuities in the peel resistance can be provided in certain areas.

[0004] US Patent 8,685,194 B2 describes a method for manufacturing adhesive closures. In one embodiment, the method involves forming discrete anti-peel flaps in an adhesive by means of a plurality of slits. The flaps are pivotable relative to a plane of a carrier material, for example, and are suitable for producing the effect described above of converting a peel principle into a push principle during the detachment process of the adhesive from a corresponding counterpart. In some cases, the slits are formed on free edges of the adhesive. Object of the invention

[0005] The object of the invention is to create a bonding system which, by utilizing the known principle of the dependence of the force required to release an adhesive bond on a peel angle or a pull-off direction, offers expanded application possibilities compared to the prior art. It is further an object of the invention to provide a hygiene product and a method for releasing an adhesive bond. Description of the invention

[0006] This problem is solved by a connection system according to claim 1, a hygiene article according to claim 12, and a method according to claim 13. The dependent claims describe preferred further developments.

[0007] If a connection system of the type mentioned above is in a state in which a first pivotable part of a first adhesive is not angled relative to a bonding area of ​​the first adhesive on a support element, then free edges of the first pivotable part are not directly surrounded by adhesive elements.

[0008] In other words, this means that, even when the first adhesive element is not pivoted relative to a principal plane of the planar support element and / or a part of the first adhesive element attached to the support element, no further adhesive elements are directly adjacent to the free edges of the first pivotable part on either side along the extent of the free edges. Thus, at least on one side of each edge, no adhesive elements are present within a distance that is less than or equal to the average distance between a plurality of the adhesive elements of the first adhesive element.

[0009] Preferably, the first pivotable part has an at least approximately rectangular shape, with three of the sides of the approximate rectangle forming free edges, the edge opposite the bonding area simultaneously representing a first free end of the first adhesive. However, a differently shaped first pivotable part is also conceivable. For example, the first free end can be rounded, which may result in a single curved free edge. However, this curved edge, along its length, reflects the free edges of the approximate rectangular arrangement and is therefore considered, in this context, as 'multiple free edges with a smooth transition'. Furthermore, the first free end can be frayed or have multiple points, resulting in a plurality of free edges.

[0010] The maximum extension of a line from the first free end of the first adhesive element, in its longitudinal direction, to the beginning of the bonding area determines the length L of the first pivotable part of the first adhesive element. The maximum extension of the first adhesive element perpendicular to the length L determines its width B. Preferably, the support element has the same width or a greater width than the first adhesive element.

[0011] The first adhesive has the majority of the adhesive elements, wherein at least one of the adhesive elements, but preferably several of the adhesive elements, is / are arranged or formed on the first pivotable part.

[0012] The carrier element is preferably designed as a flexible band. In particular, the carrier element also has a free end. If the first adhesive is attached to a second adhesive, the adhesive bond can be broken by grasping the carrier element. A user will intuitively attempt to break the adhesive bond by peeling off the carrier element. However, until the bonding area is reached, only the carrier element is moved during this peeling attempt. If the peeling of the carrier element continues, a tensile force is exerted on the first adhesive once an imaginary peeling front reaches the bonding area. The force required to break the adhesive bond is considerably greater than the force that would be needed to actually peel off the first adhesive.

[0013] To achieve the actual peeling action, the user must pull the free end of the carrier element in the opposite direction to the intuitively chosen peeling direction. The applied force is then transferred along a free length of the carrier element to the bonding area, where a peeling front begins. Due to the contrast between the intended method for separating the adhesive and the intuitively obvious method, the connection system possesses a safety feature. This prevents the adhesive bond from being carelessly loosened, especially by small children. Furthermore, implementing this safety feature is straightforward from a production standpoint.

[0014] In a preferred embodiment of the connection system, the entirety of the adhesive elements of the first adhesive is arranged or formed on the first pivotable part of the first adhesive and / or on a second pivotable part of the first adhesive. The second pivotable part is used in a further development of the invention, which will be explained later.

[0015] To avoid encountering additional resistance to a peeling front beginning at the transition between the connection area and the first pivotable part, it can be advantageous if the connection area is not covered with adhesive elements. However, design variants are also conceivable in which the connection area, or a portion thereof, has adhesive elements. If the entire connection area has adhesive elements with the same surface density as the first pivotable part, it can be advantageous to minimize the area of ​​the connection area compared to the area of ​​the first pivotable part.

[0016] Preferably, the first pivotable part of the first adhesive is a planar strip, wherein the ratio of the length L to the width B is in the range between 0.1:1 and 4:1, in particular between 0.2:1 and 2:1.

[0017] The bonding of the first adhesive to the carrier element can be achieved in particular by means of a suitable adhesive or a thermal joining process.

[0018] The adhesive elements of the first adhesive can be, in particular, hook elements, mushroom-shaped adhesive elements, or palm-shaped adhesive elements of a hook-and-loop or clip fastener. It is equally conceivable that the first adhesive element comprises loops and / or fibers of a loop tape, velour tape, non-woven fabric, or a woven, knitted, or crocheted fabric.

[0019] In another embodiment, the first adhesive can have nano- and / or microstructures. In particular, the first adhesive can have protrusions with an areal density of 10,000 to 100,000 protrusions per cm². 2These surface densities result in a strong adhesive force on a sufficiently smooth mating surface. The projections can have a height of at least 20 µm, at least 30 µm, or at least 40 µm. The projections typically have a height not exceeding 800 µm, and in particular not exceeding 150 µm. The aspect ratio of the projections, i.e., the ratio of the height to the width of the projections, is preferably between 0.1 and 3.0.

[0020] Preferably, the first adhesive and / or the carrier element comprises / comprise a plastic. Suitable examples include polypropylene, polyamide, polyethylene, polyurethane, polysiloxane, and / or a thermoplastic elastomer. Particularly preferably, the carrier element and / or the first adhesive comprises / comprises a bio-based and / or biodegradable plastic material. Suitable examples include polycaprolactone, polybutyrate, polybutylene succinate, cellulose acetate, bio-based polyethylene, polyethylene furanoate, bio-based polyamide, bio-based polyethylene terephthalate, bio-based polypropylene, polylactide, starch-based plastic, and / or polyhydroxalkanoate.

[0021] The maximum extent of a line extending from the free end of the support element, along its longitudinal direction, to the beginning of the connection area determines the free length T of the support element. The length T can preferably be up to 500% of the length L of the first pivotable part of the first adhesive. If the length L is to be greater than the length T, the length L can alternatively be up to 500% of the length T. Preferably, the length T lies within a range of ± 20% of the length L of the first pivotable part of the first adhesive.

[0022] In a further development of the invention, the first adhesive has a second free end opposite the first free end, with the bonding area located between the first and second free ends. The first adhesive has this second pivotable part. In this further development, simply peeling off the adhered first adhesive along length L using the carrier element is no longer possible, as a peeling front would have to extend from the bonding area in two opposite directions. Thus, in this further development, a particularly difficult-to-release adhesive bond can be created. This bond can advantageously be released, in particular, by pulling it transversely (along width B), although even in this case a relatively high force is required, since the force applied when pulling the carrier element transversely is not entirely sufficient to form a peeling front.

[0023] The same effect can be achieved by arranging or forming a further first adhesive on the carrier element, wherein the further first adhesive is rotated by 180° in a plane of the carrier element relative to the first adhesive, wherein the bonding area of ​​the first adhesive and a further bonding area of ​​the further first adhesive are closer to each other than the respective first free ends of the two first adhesives.

[0024] The length of the connection area and, if applicable, the further connection area, is preferably in the range of 0.1 mm to 10 mm. If the further connection area is present, the distance between the connection areas is preferably in the range of 0.1 mm to 100 mm.

[0025] The bonding system preferably further comprises a second adhesive, wherein the second adhesive is suitable for forming an adhesive bond with the first adhesive and / or the second first adhesive. For this purpose, it may, in particular, comprise hook elements, mushroom-shaped adhesive elements, or palm-shaped adhesive elements, or fibers and / or loops of a hook-and-loop tape, velour tape, nonwoven fabric, or a woven, knitted, or crocheted fabric. In the event that the first adhesive and / or the second first adhesive has nano- and / or microstructures, the second adhesive may preferably have a sufficiently smooth surface, for example, in the form of a film, to interact with the first adhesive.

[0026] The closure of a hygiene product, particularly a diaper, can be advantageously achieved using the connection system. An end of the carrier element opposite its free end is attached to the hygiene product. This attachment of the carrier element to the hygiene product can preferably be achieved using an adhesive or a thermal joining process. In particular, the assembly of the hygiene product, the carrier element, and the first adhesive (and optionally, the second first adhesive) can be carried out in a single production step. It is also conceivable that the carrier element is formed as an integral part of the hygiene product, with the attached end of the carrier element being marked by the transition between the main body of the hygiene product and the carrier element. Alternatively, the carrier element can be sewn to the main body of the hygiene product.

[0027] The carrier element, in conjunction with the first adhesive (and, if applicable, the second first adhesive), forms a closure flap of the hygiene product. Preferably, the hygiene product also includes the second adhesive.

[0028] The fastening flap can be located directly on the body of the hygiene product. In particular, the fastening flap can be located directly on the diaper body. Alternatively, the fastening flap can be located on the body of the hygiene product via another layer, especially in the form of a so-called ear, i.e., an ear-shaped layer. For example, the fastening flap can be located on the diaper body via a diaper ear.

[0029] The problem is further solved by a method for breaking an adhesive bond in a connection system comprising the first adhesive (and, if applicable, the second first adhesive) and the second adhesive. The method involves displacing the free end of the carrier element in a direction from the bonded end of the carrier element towards the free end of the carrier element, i.e., pulling the carrier element away from the bonded end, in order to peel the first adhesive from the second adhesive. This corresponds to the counterintuitive approach described above for breaking an adhesive bond of this type. In particular, if peeling is completely prevented or hindered by a corresponding design of the first adhesive and / or the second first adhesive in the aforementioned direction, the method involves pulling the carrier element perpendicular to this direction. This causes the first adhesive and / or, if applicable, the second adhesive to be peeled away from the first adhesive.the first adhesive is separated from the second adhesive.

[0030] Further advantages of the invention will become apparent from the description and the drawing. Likewise, the features mentioned above and those described in more detail below can each be used individually or in any combination according to the invention.

Detailed description of the invention and drawing

[0032] Fig. Figure 1a shows a perspective view of a connection system 10 with a first adhesive element 12, which has three free edges 11, 13, and 15. The free edge 13 also forms a first free end 20 of the first adhesive element 12. The first adhesive element 12 is arranged in a connection area 16 on a support element 14. A first pivotable part 24 of the first adhesive element 12 adjoins the connection area 16.

[0033] The first pivotable part 24 can be pivoted relative to the support element 14 and the connection area 16 and has a length L from the free edge 13 to the beginning of the connection area 16 and a width B from the free edge 11 to the free edge 15. The support element 14 is shown in section. It has a free end 22, where length T denotes the maximum length of the support element 14 from the free end 22 to the beginning of the connection area 16. In this case, length T is greater than length L.

[0034] In the illustrated embodiment, the first adhesive 12 carries a multitude of mushroom-shaped adhesive elements 18. The adhesive elements 18 occupy both the first pivotable part 24 and the connection area 16. In further embodiments (see Fig. 6a and Fig. 7) The connection area 16 does not have any adhesive elements 18. It is also conceivable that the first pivotable part 24 is designed on the support element 14 in such a way that the connection area 16 is not perceptible as a separate area, i.e., it is part of the material of the support element 14 (not shown). Areas of the support element 14 not connected to the first adhesive element 12 can also be pivoted relative to the first adhesive element 12 in the case of a flexible design of the support element 14.

[0035] Fig. Figure 1b shows another perspective view of the connection system 10. Fig. 1a. The support element 14 is shown in section, and the first pivotable part 24 of the first adhesive 12 is pivoted relative to the support element 14 and the connection area 16. In the illustrated embodiment, the first adhesive is arranged on the support element 14 by means of an adhesive 26.

[0036] Fig. Figure 2a shows a partial view of another variant of a connection system 10, wherein the connection system 10 comprises a first adhesive 12 and a support element 14, which are analogous to the embodiment in the Fig. 1a and Fig. 1b are designed. Furthermore, the connection system 10 has a second adhesive 28, here in the form of a hook and loop fastener 32. Loops 30 of the hook and loop fastener 32 are partially interlocked with mushroom-shaped adhesive elements 18 of the first adhesive 12. In Fig. Figure 2a schematically depicts a state during the separation of the first adhesive 12 from the second adhesive 28. The support element 14 is thereby attached at its free end 22 (see Figure 2). Fig. 1a) grasped, pulled in the direction of the area still attached in the illustration and at the same time lifted off from the second adhesive 28 (corresponds in the illustration to a direction of pull indicated by an arrow 52).

[0037] After the bonding area 16 has been separated from the second adhesive 28, a peeling front with a peeling angle α is formed (compare to this Fig. 2b) In a hypothetical separation attempt by intuitively peeling off the carrier element 14 (along a direction of pull 53), the first adhesive 12 would not peel off the second adhesive 28. Instead, the first adhesive 12 would have to be pulled off the second adhesive 28 over its entire surface with considerable force.

[0038] Fig. Figure 2b shows a simplified relationship between the peel angle α in a range from 180° to 90° and a relationship for removing the first adhesive 12 (see Fig. 2a) of the second adhesive 28 (see Fig. 2a) Initial force F to be applied. Preferably α lies between 160° and 90°.

[0039] Fig. 3, Fig. 4 and Fig. Figure 5 each shows further variants of a connection system 10 in excerpts. The representation includes, in analogy to Fig. 2a each shows a section of a first adhesive 12 and a second adhesive 28, which are partially adhered to each other. The bonding systems 10 differ in the type of adhesives 12 and 28 used. In Fig. 3 has a first adhesive 12 palm-shaped adhesive elements 34, while a second adhesive 28 has loops 30 of a fabric 36. In Fig. 4 has a first adhesive element 12 hook elements 38 for interaction with loops 30 of a bicycle strap 40. In Fig. In contrast, 5 has a first adhesive 12 nano- and / or microstructures 42, while a second adhesive 28 has a smooth surface 44.

[0040] Fig. Figure 6a shows a perspective view of another variant of a connection system 10, wherein a first adhesive element 12 has a first free end 20 and a second free end 21. A support element 14 is again shown in partial view. A connection area 16 of the first adhesive element 12 is located between the first free end 20 and the second free end 21. In the illustrated embodiment, the connection area 16 does not carry any of the mushroom-shaped adhesive elements 18.

[0041] Fig. Figure 6b shows another perspective view of the connection system 10. Fig. 6a. It is evident that the first adhesive 12 has a first pivotable part 24 with a length L and a second pivotable part 25 with a length I. The lengths L and I can be equal, as shown. However, this is not mandatory. The length of the bonding area 16 can be selected depending on the application.

[0042] Fig. Figure 6c shows a section of a connection system 10 in a side view. The connection system 10 features the [missing information]. Fig. 6a and Fig. Figure 6b shows the first adhesive element 12 with the first pivotable part 24 and the second pivotable part 25, as well as the support element 14. The connection system 10 also includes a second adhesive element 28, which is partially adhered to the first adhesive element 12. The second adhesive element 28 comprises fibers 29 of a nonwoven fabric 31.

[0043] Fig. Figure 7 shows a partial perspective view of another variant of a connection system 10. A first adhesive element 12 has a first free end 20, a connection area 16, and a first pivotable part 24. A further first adhesive element 12' is arranged on a support element 14, rotated 180° relative to the first adhesive element 12. Analogous to the first adhesive element 12, this further first adhesive element 12' has a further first free end 20', a further connection area 16', and a further first pivotable part 24'. By means of the arrangement shown, the connection system 10 is designed to be installed in the following configuration: Fig. 6a and Fig. The connection system 10 shown in 6b is functionally replicated. A length L' of the further first pivotable part 24' can be, as shown, the length L (see Fig. 1a) of the first pivotable part 24 correspond to or differ from it. It is also conceivable that the two first adhesive elements 12, 12' differ in their width or with regard to the dimensions of their respective connection areas 16, 16'. Furthermore, it is conceivable that the first adhesive element 12 and the second first adhesive element 12' each have different adhesive elements 18 (compare Fig. 3, Fig. 4 and Fig. 5) are occupied.

[0044] Fig. Figure 8 shows a hygiene article 46, wherein a connection system 10 in one of the presented variants forms a closure flap 48 of the hygiene article 46. A first adhesive 12 (not visible here, see e.g. Fig. 1a) is attached to a hook and loop fastener 32, which in turn is arranged or formed on the hygiene article 46. A carrier element 14 of the connection system 10 has an end 50 attached to the hygiene article 46 and a free end 22. Assuming that the connection system 10 is as described in Fig. As shown in Figure 2a, the locking tab 48 can be easily released by pulling on the free end 22 of the carrier element 14 in a direction from its attached end 50 towards the free end 22. However, if the free end 22 of the carrier element 14 is intuitively peeled back towards the attached end 50, releasing the locking tab 48 is only possible with a comparatively high force.

[0045] Fig. Figure 9 shows a diagram of a method 100 for solving a connection system 10 (see e.g. Fig. 8). Process step i involves drawing a support element 14 (see Fig. 8) in a direction away from a tied end 50 (see Fig. 8) of the support element 14 or, in particular in the case where a second free end 21 (see Fig. 6a) and / or another first free end 20' (see Fig. 7) on a first adhesive 12 (see e.g. Fig. 7) is present, the pulling of the support element 14 transversely in a direction from the bound end 50 of the support element 14 to the free end 22 of the support element 14. This results in the separation of the first adhesive 12 and / or a further first adhesive 12' (see Fig. 7) from a second adhesive 28 (see e.g. Fig. 2a).

[0046] Referring to the figures in the drawing, the invention relates to a connection system 10 with a first adhesive element 12, which has a plurality of adhesive elements 18, 29, 30, 34, 38, 42. The first adhesive element 12 has a first free end 20 and a connection area 16, wherein the connection area 16 is arranged on or formed on a support element 14, preferably designed as a flexible band. A first pivotable part 24 of the first adhesive element 12 is movable relative to the support element 14, in particular pivotable. The first pivotable part 24 has free edges 11, 13, 15. In a state in which the first pivotable part 24 is not pivoted relative to the attachment area 16, i.e. in which both lie in a common plane, the free edges 11, 13, 15 in this plane are not immediately surrounded by adhesive elements 18, 29, 30, 34, 38, 42 of the first adhesive 12.The invention also relates to a method 100 for releasing such a connection system 10, wherein the connection system 10 comprises a second adhesive 28.
