The invention relates to a diaper fastening tape which is Z-folded in a ready state and has the features of the preamble of claims 1, 9, 10 and 11. The invention also relates to a semifinished product strip for producing such a diaper fastening tape and a diaper with such a diaper fastening tape.

Generic diaper fastening tapes are, for example, from the WO 2018/142255 A1 , of the EP 1 214 034 Bl, the EP 2 162 108 , B1, the EP 1 424 976 B1 , of the WO 2017/180702 A1 , of the JP 40596988 , of the JP 4243111 or from the JP 4244297 known.

It is an object of the present invention to provide a diaper fastening tape which can be stably attached to a diaper in a structurally relatively simple manner and yet can be deployed reliably.

The object of the invention is achieved by diaper fastening tapes, semifinished product strips and diapers with the features of the independent claims. Further, possibly also independent, advantageous configurations can be found in the subclaims and the following description.

In order to provide a diaper fastening tape which can be attached to a diaper in a structurally relatively simple manner and which can nevertheless be deployed in a reliable manner, a Z-folded diaper fastening tape with a folded ready state and with an unfolded closed state for closing a diaper which has a user tape section releasably attaching the diaper fastening tape to the diaper or to a diaper section, a deployment tape section for unfolding the diaper fastening tape and a permanent tape section for permanently fastening the diaper fastening tape to the diaper or to a diaper section, wherein a user-side fold is arranged between the user tape section and the unfolding tape section and between the Unfolding tape section and the permanent tape section is arranged a permanent folding, the permanent tape section having a permanent side with a Includes a permanent tape section inner surface and a side opposite the permanent side, wherein on the permanent tape section inner surface there is an adhesive area on the permanent tape section side and the adhesive area comprises a permanent adhesive layer, the user tape section comprising a user tape section inner surface oriented in the direction of the permanent side, a first adhesive area and on the user tape section inner surface a second adhesive area is arranged, the first adhesive area comprising a first user adhesive layer and the second adhesive area comprising a second user adhesive layer, the unfolding tape section in the provision state comprising an unfolding tape section inner surface oriented in the direction of the permanent side, an adhesive area being arranged on the unfolding tape section inner surface, wherein the adhesive area is a deployment adhesive layer t comprises, wherein a finger lift is arranged on one end of the user tape section facing away from the user-side folding on the user tape section inner surface, characterized in that the diaper fastening tape comprises an anchor tape section that extends the permanent tape section via the permanent-side folding for permanently fastening the diaper fastening tape to the diaper or to the diaper section, wherein the anchor band section comprises an anchor band section inner surface oriented in the direction of the permanent side, an adhesive region on the anchor band section inner surface being arranged and an area which is non-adhesive in the direction of the permanent side being provided between the anchor band section side adhesive region and the permanent band section side adhesive region.

In addition to the permanent part, which in itself serves for the permanent fastening of the diaper fastening tape, the anchor part can provide additional permanent acting adhesion, so that the permanent adhesion of the diaper fastening tape can be strengthened overall.

In a correspondingly advantageous embodiment, the non-adhesive region can achieve a particularly high stability of the overall arrangement. Forces can be better distributed through the non-adhesive area to the adjacent adhesive areas, so that the application of force can be optimized, since corresponding forces are then introduced more evenly in the area of the non-adhesive area, which can be found between the anchor tape and the permanent tape can be. In this way, possible forces that could impair the stability of the overall system can be prevented.

Preferably at least 90% of the distance along the user band section is formed from a user part, at least 90% of the distance along the unfolding band section is formed from an unfolding part, at least 90% of the distance along the permanent band section is formed from a permanent part or at least 90% of the distance along the anchor band section out formed an anchor part. In this way, a user part for releasably fastening the diaper fastening tape, an unfolding part for unfolding the diaper fastening tape, a permanent part for permanently fastening the diaper fastening tape and an anchor part for additionally permanently fastening the diaper fastening tape can be provided.

Since it may not be necessary for each of the individual band sections mentioned to perform the task of releasable fastening, unfolding or permanent fastening over their full length, but rather a small part of the individual sections can serve other purposes, such as, for example, connecting the band sections to one another in each case only at least 90% of the distance along the individual belt sections can be formed from the corresponding parts in order to fulfill the corresponding task. The remaining areas can be formed, for example, by other assemblies or can be used for other purposes, for example the connection to other assemblies and the like.

It is advantageous if the anchor part is arranged on the end face on the side of the permanent-side fold opposite the permanent part, since on the one hand the anchor part can be arranged on the permanent part as simply as possible in terms of process technology. On the other hand, an optimal distribution of forces between the anchor part and the permanent part can take place.

In order to provide a firm connection between the anchor part and the permanent part, the anchor part can be connected to the permanent part by means of a lamination or fastening tape. Such a connection is particularly easy to implement in terms of process technology. In this way, a uniform distribution of forces between the anchor part and the permanent part can also take place. The power transmission to the anchor part and the permanent part itself can also take place via this laminating or fastening tape. A non-adhesive area can also be provided by a lamination tape provided at this point, regardless of whether this is used as a fastening tape, by arranging it accordingly. Regardless of the use of a lamination tape, the fastening tape serves to provide a connection between the anchor part and the permanent part, so as to create a stable connection which stabilizes the connection to a diaper or a diaper ear if the non-adhesive area can be provided in another way.

In addition, the lamination or fastening tape itself can be used to implement the non-adhesive region between the adhesive area on the anchor tape section side and the adhesive area on the permanent tape section side. It goes without saying that for this purpose the laminating or fastening tape can be arranged on the adhesive area on the permanent tape section side.

Advantageously, the lamination or fastening tape partly adheres to the anchor part and partly to the permanent part or conceals the two parts, as a result of which the anchor part and the permanent part can be fastened to one another and in favor of the strongest possible permanent adhesion and good force transmission to the two parts can be.

It is advantageous if the adhesive region on the anchor tape section side comprises an anchor adhesive layer and the anchor adhesive layer and the permanent adhesive layer are formed continuously. In this way, the best possible adhesive properties can be achieved for the anchor adhesive layer, which are crucial for permanent adhesion. It goes without saying that, in different embodiments, discontinuously formed adhesive layers are also possible in addition to continuously formed adhesive layers. The latter also have non-adhesive areas in their adhesive layer, while only adhesive areas are provided in the case of a continuously formed adhesive layer. Also, regardless of the other features of the present invention, it is easy to provide a continuous adhesive layer, since then there is no need to pay attention to any accuracies.

An intimate and thus also stable connection between the unfolding part on the one hand and the permanent part or the user part on the other hand can be ensured if the user band section and / or the permanent band section is at least partially formed from the unfolding part, which then accordingly in the respective band section, i.e. in the user band section or the permanent band section, where a corresponding connection can then be provided. The unfolding part then preferably has a kink line at the transition to the respective band section, so that the basic structure can be ensured in a simple and compact manner and nevertheless with a secure connection. An intimate and thus also stable connection between the deployment part on the one hand and the permanent part or the user part on the other hand can alternatively or cumulatively be ensured by the deployment band section being at least partially formed from the permanent part or the user part. This enables the permanent part or the user part to extend into the unfolding band section and then there to be connected accordingly to the unfolding part. This also enables a simple and compact construction with a secure connection, it then being advantageous if the permanent or user parts reaching into the unfolding band section are correspondingly bent at the transition of the respective band section.

It goes without saying that the parts, that is to say the permanent part, the user part, the unfolding part and / or the anchor part, should each be formed separately as individual parts which are then connected accordingly, in order to identify the respective parts as separate parts. In particular, such a configuration enables the parts to be made from different materials and, if appropriate, also to be coated in a process-technically simple manner with different coatings, for example with different adhesives adapted for the respective purpose of the corresponding part.

In order to provide a diaper fastening tape which can be stably attached to a diaper in a structurally relatively simple manner and which can nevertheless be deployed in a reliable manner, a Z-folded diaper fastening tape with a folded ready state and with an unfolded closed state for closing a diaper, which one User tape section for releasably attaching the diaper fastening tape to the diaper or to a diaper section, a deployment tape section for unfolding the diaper fastening tape and a permanent tape section for permanently attaching the diaper fastening tape to the diaper or to a diaper section, a user-side fold being arranged between the user tape section and the unfolding tape section and a permanent folding is arranged between the unfolding band section and the permanent band section, the permanent band section having a permanent side with a r comprises an inner surface of the permanent tape section and a side opposite the permanent side, wherein an adhesive area is arranged on the permanent tape section inner surface and the adhesive area comprises a permanent adhesive layer, the user tape section comprising a user tape section inner surface oriented in the direction of the permanent side, a first adhesive area on the user tape section inner surface and a second adhesive area are arranged, the first adhesive area comprising a first user adhesive layer and the second adhesive area comprising a second user adhesive layer, the unfolding tape section in the provision state comprising an unfolding tape section inner surface oriented in the direction of the permanent side, an adhesive area being arranged on the unfolding tape section inner surface, wherein the adhesive area is a deployment adhesive ski ct, wherein a finger lift is arranged on the end of the user band section facing away from the user-side folding on the user band section inner surface, characterized in that at least 90% of the route along the user band section is formed from a user part made of non-woven, at least 90% of the route along the unfolding band section a deployment part is made of film, at least 90% of the distance along the permanent band section is made of a permanent part made of film and the finger lift is made of film or nonwoven.

The user part is touched by the user when using the diaper fastening tape, whereby a user part made of NonWoven can be perceived by the user as particularly pleasant in terms of appearance and feel. Since the finger lift is also intended for direct contact with the user, it can also be made of non-woven material due to the optically and haptically pleasant properties for the user, alternatively the finger lift can also be made of film, which then delimits it in particular easily distinguishable from the user part, in particular easily distinguishable in terms of haptics, so that it can be easily grasped. Because the unfolding part and the permanent part are essentially insignificant to the user in terms of haptics, these parts can be formed from a less expensive film, which is easier and less expensive to adapt to the interaction with the adhesive, particularly with regard to contact with adhesive, than NonWoven.

Insofar as, as already described above, parts such as the user part, the permanent part or the unfolding part can overlap into adjacent sections, it is conceivable not to design the entire sections accordingly, but only to provide a 90% distance, so that a a corresponding overlap appears to be possible, the remaining 10% not being noticed in such a way that the overall properties of the respective section are influenced in a particularly disadvantageous manner. It goes without saying that a smaller overlap is also conceivable.

In addition, in order to provide a diaper fastener tape which can be stably attached to a diaper in a structurally relatively simple manner and yet can be deployed in a reliable manner, a Z-folded diaper fastener tape with a folded ready state and with one unfolded Closing state for closing a diaper, which comprises a user band section for releasably attaching the diaper fastening tape to the diaper or to a diaper section, a deployment band section for unfolding the diaper fastening tape and a permanent band section for permanently fastening the diaper fastening tape to the diaper or to a diaper section, wherein between the user band section and a user-side fold is arranged on the unfolding tape section and a permanent-side fold is arranged between the unfolding tape section and the permanent tape section, the permanent tape section comprising a permanent side with a permanent tape section inner surface and a side opposite the permanent side, wherein an adhesive area is arranged on the permanent tape section inner surface and the adhesive area comprises a permanent adhesive layer, the user tape section in the ready state comprises a user tape section inner surface oriented in the direction of the permanent side, a first adhesive area and a second adhesive area being arranged on the user tape section inner surface, the first adhesive area comprising a first user adhesive layer and the second adhesive area including a second user adhesive layer, the unfolding tape section in the ready state comprises an unfolding band section inner surface oriented in the direction of the permanent side, an adhesive region being arranged on the unfolding band section inner surface, the adhesive region comprising a unfolding adhesive layer, a finger lift being arranged on an end of the user band section facing away from the user on the user band section inner surface, characterized in that Diaper fastening tape exclusively adhesive functional areas for holding in the ready state and to interact with the diaper.

This makes it possible, for example, to dispense with hooking connection elements or other connections, such as welds and the like. By using exclusively adhesive functional areas, with a suitable design, both the manufacture and the provision of the diaper fastening tape can be simplified, which in the end also minimizes the costs.

In this context, it should be emphasized that the term “functional area” in the present case describes the area of the diaper fastening tape, to which those attaching it to the diaper, be it a releasable or permanent fastening, or holding the diaper fastening tape in its folded ready state, have a functional meaning a connection function to the diaper or a holding function of the individual diaper fastening tape sections to one another.

With a suitable design, the restriction to adhesive or adhesive functional areas in addition to simple manufacture also enables a particularly flat and compact structure, which in turn has a cost-saving effect with regard to the selection of the adhesives and the materials for the individual tape sections.

In order to provide a diaper fastening tape which can be stably attached to a diaper in a structurally relatively simple manner and which can nevertheless be deployed in a manner that is reliable in operation, a Z-folded diaper fastening tape with a folded ready state and with an unfolded closed state for closing one can alternatively be used Diaper comprising a user tape section for releasably attaching the diaper fastener tape to the diaper or to a diaper section, a deployment tape section for deploying the diaper fastener tape and a permanent tape section for permanently attaching the diaper fastener tape to the diaper or to a diaper section, with a user side between the user tape section and the deployment tape section Folding is arranged and a permanent folding is arranged between the unfolding band section and the permanent band section, the permanent band section e comprises a permanent side with a permanent band section inner surface and a side opposite the permanent side, wherein an adhesive region is arranged on the permanent band section inner surface and the adhesive region comprises a permanent adhesive layer, the user band section comprising a user band section inner surface oriented in the direction of the permanent side, wherein on the user band section inner surface the first adhesive area and a second adhesive area are arranged, the first adhesive area comprising a first user adhesive layer and the second adhesive area comprising a second user adhesive layer, the unfolding tape section comprising an unfolded tape section inner surface oriented in the direction of the permanent side, an adhesive area on the unfolded tape section inner surface is arranged, the adhesive region ei ne unfolding adhesive layer, wherein a finger lift is arranged on one end of the user tape section facing away from the user-side folding on the user tape section inner surface, characterized in that the user tape section between the two adhesive areas one in the direction the permanent side has a non-adhesive area and / or that the unfolding tape section between the unfolding adhesive layer and the user-side fold has a non-adhesive area in the direction of the permanent side.

In both of the above-mentioned designs, there is a discontinuous adhesive coating which aims to save adhesive while making the process simple. In addition, the adhesive-free areas can also serve for easier unfolding when opening, that is to say when pulling off the band section, due to an improved tensile effect. Due to the adhesive not provided at these points, the corresponding band section can easily come loose at these points, so that a further separation of the band sections connected by an adhesive layer can take place in a substantially simpler and more reliable manner with an otherwise favorable design of the diaper closure band.

In addition, the adhesive-free areas can ensure reliable use of the diaper fastening tape. For example, in the absence of the non-adhesive area between the two adhesive areas of the user tape section, deployment difficulties could arise, since, for example, excess adhesive from the other tape sections could penetrate through these tape sections and the diaper fastening tape would be unusable in the event of such an unfavorable incident.

Here, the non-adhesive area of the user tape section is preferably in the area of the permanent folding between the unfolding tape section and the permanent tape section. This means that the user tape section, with its non-adhesive area, cannot attack the permanent fold, which could otherwise lead to excessive loads, which would then lead to problems when opening the fold. This means that any connections between the permanent band section and the unfolding band section can then be made with a correspondingly lower strength and therefore more cost-effectively, or that the # diaper fastening band can be deployed there in a more reliable manner.

In particular, it is advantageous if the non-adhesive area of the user tape section is arranged between the two adhesive areas, since then the adhesive area coming into contact with the unfolding tape is effective and the non-adhesive area nevertheless enables reliable detachment during the The adhesive area of the user band section facing the finger lift naturally does not come into contact with the unfolding band in the folded state and is therefore relatively easy to release. Possibly. lies this adhesive area facing the finger lift on the anchor band section, whereby it does not adhere too much to the anchor band because of the height of the unfolding band and because of the permanent folding, or because the anchor band section is relatively firmly connected to the diaper, it is pulled off well can. Even the non-adhesive region between the adhesive band section-side adhesive region and the permanent band section-side adhesive region can, in a suitable embodiment, facilitate peeling off the finger-lift-side adhesive region of the user band section from the anchor band section, since the anchor band section and the permanent band section close to the transition between anchor band section and permanent section or in can give in a little bit near the permanent fold.

Also in the area of the folding by the user, if the diaper fastening tape is to be unfolded, considerable forces can act in the diaper fastening tape if an adhesive holding down the folding, such as the unfolding adhesive layer, is to be detached. However, if a non-adhesive area is provided between this holding down adhesive, for example the unfolding adhesive layer, and the folding on the user side, the forces which then act as separators can be better introduced into the diaper fastening tape, so that the separation takes place more gently. This also means that, with a suitable design, less expensive materials or adhesives can be used without the risk of damage during an unfolding process becoming too great.

The end of the unfolding part facing the user-side folding is preferably folded in the user-side folding and connected to the unfolded user part. In this way, the unfolding part can be connected to the user part in a manner which is particularly advantageous in terms of process technology, so that it is also possible for the diaper fastening tape to be produced inexpensively. This also enables a stable formation of this connection.

Accordingly, it can be advantageous for a process-technically simple and inexpensive production if the end of the permanent part facing the permanent folding is folded and connected to the unfolded unfolding part.

The user tape section is a section of the diaper fastener tape that serves the To fasten the diaper fastening tape releasably to the diaper or to a diaper section and for this purpose is also taken by the user at a given time.

A diaper can generally consist of several elements or have different sections that perform different tasks. It can make sense for the user band section to be releasably attached to a very specific diaper section, for example to a front tape, a landing tape or the like. For example, the diaper section is particularly useful, from which a used diaper can be closed as simply and reliably as possible. In particular if the diaper is designed as diaper pants, it can be advantageous to releasably attach the user band section in an area of the back sheet or, for example, to a landing tape that has already been attached to the diaper in a suitable position, so that the diaper pants or the diaper are then in can be closed in a reliable manner according to a disposal position by the diaper fastening tape.

The user tape section is preferably kept ready when the diaper fastening tape is in a ready state. The user band section can then be gripped by a user, the diaper closure band unfolded and then fastened to the diaper again in an unfolded closed state.

For this purpose, the user tape section has a user tape section inner surface with two adhesive areas which are formed from a user adhesive layer. This user adhesive layer has the corresponding detachable fastening properties for the detachable fastening of the diaper fastening tape to the diaper. In the ready state, the user adhesive layer serves to hold the diaper fastening tape together in the ready state. In the unfolded state, however, the user adhesive layer serves to fasten the diaper fastening tape to the diaper or to a diaper section.

The unfolding tape section also has a unfolding adhesive layer which is arranged on the inside of the unfolding tape section. This serves to hold the diaper fastening tape in the ready state, the unfolding adhesive layer then being connected to the permanent tape section. The unfolding adhesive layer is also designed for a detachable connection so that the diaper fastening tape can be unfolded, the unfolding adhesive layer detaching from the permanent tape section. In the unfolded closed state, the unfolding adhesive layer is no longer of any significant importance, since it is then no longer connected to any other element.

The unfolding band section per se thus enables a construction of the diaper fastener tape, with which a diaper fastener tape can be unfolded from a ready state to a closed state with a very large extension, and thus also the actual Z-fold of the Z-folded diaper fastener tape.

The permanent tape section serves to permanently fasten the diaper fastening tape to the diaper or to a diaper section. Here, an adhesive area is arranged on the inner surface of the permanent tape section, which comprises a permanent adhesive layer. This permanent adhesive layer is designed in such a way that the attachment to the diaper is then non-detachable or is non-destructively detachable.

Since the permanent tape section of the diaper fastening tape is to remain permanently on the diaper, there is also no detachable fastening for the permanent adhesive layer. Such would even be disadvantageous for the actual purpose, since the permanent tape section should not, for example, unintentionally detach from the diaper or a diaper section. Instead, this should remain safely on the diaper. In this way, with a suitable design, it can in particular be ensured that the diaper fastening tape can then be fastened to the diaper with the user tape section by the user in the desired manner even when the diaper is closed, and that the diaper can be closed in a reliable manner.

In order to produce diaper fastening tapes as efficiently as possible, a semifinished product strip for producing a corresponding diaper fastening tape can extend in the machine direction and the diaper fastening tape can be separated perpendicular to the machine direction. A diaper fastening tape separated in this way then preferably extends in its longitudinal direction perpendicular to the machine direction.

It is also advantageous if, in the case of a diaper, the diaper fastening tape is arranged dorsally, ventrally or in the middle of the diaper. In the case of a dorsal arrangement, the diaper fastening tape is provided on the back of the diaper, in the case of a ventral arrangement on the belly of the diaper and in the case of a central arrangement in between. It goes without saying that a plurality of diaper fastening tapes can also be arranged on a diaper, for example only one of these tapes being provided for disposal. Depending on the specific design of the diaper, for example as a pant diaper, but a corresponding diaper fastening tape can be sufficient to close the diaper in a disposal position.

It goes without saying that the features of the solutions described above or in the claims can also be combined, if appropriate, in order to be able to implement the advantages in a correspondingly cumulative manner.
