Description

[0001] The invention relates to a packaging tube closure comprising a means of providing a first-opening guarantee.

[0002] Packaging tube closures or heads for cosmetic products, pharmaceutical products or foodstuffs are usually equipped with tamper-evident devices to provide a user or consumer with reliable proof of the integrity of the original packaging.

[0003] Various solutions are known from the prior art. For example, a film, such as an aluminum or plastic film, can be attached or affixed to the tube's outlet opening, which must be removed or pierced before the first dose of product. While this solution provides clear, irreversible protection of the tube opening and thus unambiguous proof of the original packaging's integrity, it requires not only an additional step for removing or piercing the film but also the disposal of the film residue by the consumer.

[0004] Furthermore, product labels or stickers with integrated perforated tear lines are known, which are applied across the cap of the tube's outlet opening and tear when the cap is first opened. This solution eliminates a separate step for the user to open the tube's outlet and the need to dispose of film remnants; however, after opening, label edges typically remain protruding and therefore bothersome on the cap or tube head. Moreover, because of the label remaining on the tube head, clear visual proof of initial opening is usually not guaranteed.

[0005] Also known are closure elements with integrated bridges or ridges, which are molded from plastic using an injection molding process and break irreversibly upon first opening the tube's outlet cap. While this eliminates the need for additional covering with foil or a label, the break points themselves are usually difficult to detect and therefore often do not provide clear visual proof of tampering. Furthermore, this solution is generally not feasible for tube closures manufactured in an open state, i.e., where the tube outlet cap is produced in the open position and only then closed.

[0006] Based on the aforementioned prior art, the object of the present invention is to provide an improved tube head with integrated means for tamper detection, which addresses the aforementioned disadvantages of the prior art. In particular, means for tamper detection are to be provided which do not produce any separable parts or waste upon initial opening and ensure clear visibility of the initial opening.

[0007] This problem is solved by the subject matter of the independent claims. The dependent claims further describe advantageous embodiments of the invention. Furthermore, the subject matter of the invention addresses additional problems, as will be evident from the following description. Advantageous embodiments are the subject of the following description, the description of the figures, the figures themselves, and the dependent claims.

[0008] In a first aspect, the invention relates to a tube head for an arrangement on a packaging tube, comprising a shoulder for connection to a packaging tube, an outlet opening integrated into the tube head, and a lid connected to the shoulder via a hinge for selectively closing the outlet opening. The tube head includes a thin-walled cover element for indicating initial opening, in particular in the form of a label, having one or more predetermined breaking points for the defined initial opening of the cover element. According to the invention, the at least one predetermined breaking point is arranged relative to a circumferential contour of the lid such that at least one partial region of the cover element adjacent to the predetermined breaking point is concealed by the lid after initial opening, in particular concealed below the lid.

[0009] The design according to the invention guarantees highly reliable visibility of the initial opening of the tube head and thus of the associated packaging tube, while simultaneously preventing the formation of separable parts or waste during the initial opening. Furthermore, this solution is particularly advantageous for tube closures that are manufactured in an open state, i.e., where the cap of the tube outlet opening is manufactured in the open position and only subsequently closed.

[0010] The term "concealed by the lid" is understood here to mean that the corresponding sub-region of the cover element, when viewed from above, is covered by the lid after it has been closed following the initial opening and is therefore no longer visible. Advantageously, the lid covers the sub-region located beneath it when closed.

[0011] In a preferred embodiment, the predetermined breaking point comprises at least one predetermined breaking line, which is arranged to overlap the circumferential contour of the cap at least partially. This enables an optically and functionally advantageous integration of the predetermined breaking point into the design of the tube head. Furthermore, a controlled, clean separation can be ensured upon initial opening.

[0012] The predetermined breaking point advantageously comprises at least one predetermined breaking line, which extends from a lateral section or end face of the tube head, across the circumferential contour of the cap, and back to the lateral section or end face of the tube head. A predetermined breaking line of this design enables a circumferential or partially circumferential connection of the covering element around the cap, which is separated in a defined manner upon initial opening. The line's shape can be adapted to the specific cap shape.

[0013] Furthermore, the predetermined breaking point can advantageously include at least one or more simple or multiple bent, curved, or meandering predetermined breaking line. The mechanical stability of the predetermined breaking point can be specifically adjusted by the chosen line shape. For example, a meandering or bent structure can increase opening resistance and thereby prevent unintentional tearing, such as during transport. At the same time, such a shape can create a decorative or brand-defining contour.

[0014] Furthermore, the predetermined breaking point can be advantageously formed by perforations and / or indentations in the material of the cover element. This allows for simple manufacturing of the predetermined breaking point, as perforations and / or indentations can be produced using simple stamping or embossing processes. Moreover, a defined weakening of the material and thus a reproducible fracture behavior can be achieved, particularly by varying the number and / or depth of the perforations and / or indentations.

[0015] Advantageously, the section of the cover element located below the lid after initial opening comprises one or more essentially triangular or curved geometric segments. This ensures, on the one hand, a uniform tearing of the material along the predetermined breaking line. Optionally, this can also create a visually appealing effect for initial opening verification.

[0016] In a preferred embodiment, the tube head and the cap element have different colors. This makes it even clearer when the tube has been opened.

[0017] A further advantage is that the tube head lid is designed as a hinged lid, which is pivotally attached to the tube head by means of a hinge and, in the closed position, is arranged in a lid recess provided in the tube head, preferably flush with the surface. It is also advantageous that, in the closed position, the back of the lid is flush with a surface surrounding the lid, in particular the end face, of the tube head. Such a hinged lid allows for convenient one-handed operation and reduces the risk of losing separate lid parts. The preferably flush arrangement in the lid recess also contributes to a compact and hygienic overall design of the tube head.

[0018] A further advantage is the lid's circumferential contour, which is essentially U-shaped. This allows for an ergonomic lid design and simplified opening. It also facilitates easier interaction between the lid and the cover element during initial opening.

[0019] In a preferred embodiment, the tube head and / or the cap includes a recess located at least partially below the respective predetermined breaking point for at least partially receiving the portion of the cover element after initial opening. Advantageously, the recess is located in a transition area between the tube head and the cap and is spanned by the respective predetermined breaking point of the cover element in a lateral sectional view.

[0020] Such a design enables a clean and orderly collection of the torn-off part of the cover element, whereby in particular a negative influence on the lid closing process by the torn-off part and / or a disturbing protrusion of material residues after the initial opening is avoided.

[0021] Advantageously, the lid is designed and arranged in such a way that, in the closed state, it seals the outlet opening fluid-tight by means of a sealing element projecting from the lid, and in an open position, it allows the tube contents to be dispensed through the outlet opening.

[0022] A further advantage is that the cover element on the cap and a surrounding surface of the tube head is arranged in such a way that, except for the portion concealed after initial opening, the remaining cover element remains visible to the user. This provides a clear visual indication of initial opening. Furthermore, the remaining cover element can be used as a decorative or branding element.

[0023] The cover element is advantageously attached to the lid and a surrounding surface by gluing and / or welding. Gluing or welding creates a permanent and tamper-proof bond. The choice of fastening method can be adapted to the material used and the manufacturing process, thus ensuring a high level of production reliability.

[0024] Furthermore, the cover element is advantageously made of plastic, especially HDPE, and / or fibrous material, especially paper. This choice of material allows for adaptation to different recycling and sustainability requirements. While HDPE offers high density and dimensional stability, fibrous material enables a more environmentally friendly design and can also be printed or embossed to incorporate product information or brand logos.

[0025] In a further aspect, and particularly as an alternative to the embodiment described above, the invention relates to a tube head for arrangement on a packaging tube, comprising a shoulder for connection to a packaging tube, an outlet opening integrated into the tube head, and a lid connected to the shoulder via a hinge for selectively closing the outlet opening. The tube head has a projecting locking element, preferably a projecting pin, which is designed to interact with a recess arranged on the lid, having an integrated predetermined breaking point to detect initial opening. According to the invention, the predetermined breaking point of the recess is located in a separation zone that differs from the contact area of ​​the recess against which the locking element bears in a force-transmitting manner when the lid is closed.

[0026] The design according to the invention guarantees highly reliable visibility of the initial opening of the tube head and thus of the associated packaging tube, while simultaneously effectively preventing the formation of separable parts or waste during the initial opening. This solution is also particularly advantageous for tube closures that are manufactured in an open state, i.e., where the cap of the tube outlet opening is manufactured in the open position and only subsequently closed, whereby preferably no additional production step is necessary for providing the tamper-evident means. Furthermore, the separation of the contact area and the predetermined breaking point according to the invention ensures effective and reliable resealing of the cap after the initial opening.Furthermore, circumvention of the tamper-evident security measures, for example through deliberate manipulation, is made significantly more difficult compared to solutions known from the state of the art, especially PIN solutions.

[0027] In a preferred embodiment, the predetermined breaking point is arranged in a first plane, preferably perpendicular to the main axis of the tube head, and the contact area between the snap-in element and the cap is arranged in a second plane that is distinct from the first. It is further advantageous that the second plane is arranged parallel to the first plane.

[0028] By arranging the predetermined breaking point and the contact area on different planes, a clear functional separation between the opening mechanism and the holding function is provided. Furthermore, targeted force can be applied to the predetermined breaking point, thus enabling a controlled initial opening at that point.

[0029] Advantageously, the predetermined breaking point comprises a thin-walled material rib positioned between the recess and an outer surface of the lid, particularly in the area of ​​a lid engagement. This thin-walled rib allows for a controlled weakening of the material, enabling the initial opening to be achieved with a defined force. By being located in the area of ​​the lid engagement, the predetermined breaking point is advantageously situated close to the point where a user would apply force to trigger the opening.

[0030] Furthermore, the locking element extends advantageously perpendicular to a rotational axis of the lid's hinge. This perpendicular orientation of the locking element relative to the hinge axis ensures, in particular, a stable locking mechanism when the lid is closed.

[0031] Furthermore, the locking element extends advantageously onto an end face of the tube shoulder, which is covered by the cap when closed. This allows for a concealed and protected arrangement of the locking connection, thus minimizing the introduction of contaminants into the locking area. In addition, a compact and flush design is achieved.

[0032] In a preferred embodiment, a distal region of the locking element is at least partially chamfered. More preferably, the distal region of the locking element is chamfered in side view and / or has a substantially hook-shaped edge. In particular, it can be designed such that when the lid is opened, a force is generated in a horizontal direction towards the tube head and any connected tube, which prevents the locking element from slipping, especially without breaking the predetermined breaking point.

[0033] This design facilitates the locking and unlocking of the lid. In particular, the lid can glide smoothly over the angled design when closing, reducing the locking force and minimizing wear. At the same time, secure closure is ensured, with the locking element providing a barb-like function and thus increased security against tampering.

[0034] Furthermore, the recess advantageously has a star-shaped, heart-shaped, or parallelogram-shaped geometric form. This provides a functional shape with material cutouts at defined points, which can serve, in particular, to provide the predetermined breaking point and, further advantageously, the contact area for the snap-in element. Additionally, an attractive decorative form is provided, which draws the user's attention and, in particular, simplifies the user's initial identification of the opening.

[0035] A further advantage is the recess being formed in a preferably curved edge region of the lid, which extends essentially perpendicularly from a rear side of the lid, preferably located at the front. This allows for a particularly space-saving and functionally advantageous integration into the lid.

[0036] Furthermore, the lid is advantageously designed and arranged in such a way that, in the closed state, it seals the outlet opening fluid-tight by means of a sealing element projecting from the lid, and in an open position, it allows the tube contents to be dispensed through the outlet opening.

[0037] In another aspect, the invention relates to a packaging comprising a packaging tube and a tube head associated therewith as described above.

These show: Fig. Figure 1 shows a perspective view of a first preferred embodiment of the tube head according to the invention in the open state, without a cover element applied; Fig. Figure 2 shows several schematic views of the tube head according to Fig. 1 in top view, first without and with the cover element applied, in the open position at the first opening, as well as in a subsequent closed position; Fig. Figure 3 shows several schematic views of the tube head according to the invention in top view, analogous to Fig. 2, wherein the tube head additionally has at least one recess below the predetermined breaking point.

[0039] The invention is described below with reference to the Fig. 1-12 are described with reference to merely exemplary, preferred embodiments.

[0040] Fig. Figure 1 shows a perspective view of a first embodiment of the tube head 10 for arrangement on a packaging tube 40, in particular for forming a package 50. For better illustration, a cover element or label 5 to be applied was shown first (see Figure 1). Fig. 2) omitted.

[0041] The tube head 10 comprises a shoulder 1, which is designed for connection with a packaging tube 40, an outlet opening 2 integrated into the tube head, and a lid 4 connected to the shoulder 1 via a hinge 3 for selectively closing the outlet opening 2. The lid 4 is preferably designed as a hinged lid, which is pivotably attached to the tube head 10 by means of the hinge 3 and, in the closed state, is arranged in a lid recess 8 provided in the tube head. In the closed state, a rear side of the lid 4b is preferably flat with a surface 9 surrounding the lid (see figure). Fig. 2), in particular the end face, of the tube head 10. A circumferential contour 4a of the lid 4 advantageously has a substantially U-shaped contour in top view.

[0042] Fig. Figure 2 shows a top view of the tube head 10 in the upper left image according to Fig. 1 and to the right of it the cover element or label 5 to be applied. This is applied to the end face 9 of the tube head 10, for example by gluing or welding. The cover element 5 is designed as a thin-walled cover element 5 to indicate initial opening and advantageously has one or more predetermined breaking points 6a, 6b for the defined initial opening of the cover element 5.

[0043] In the applied state of the cover element 5 (see middle left illustration in Fig. 2) is arranged on the tube head 10 such that the predetermined breaking points 6a, 6b are arranged relative to a circumferential contour 4a of the lid 4 such that at least one partial region 5a of the cover element 5 adjacent to the predetermined breaking point 6a, 6b is opened after initial opening of the lid 4 (see middle right figure in Fig. 2) when the lid 4 is closed again (see bottom illustration of Fig. 2) is concealed by this, in particular concealed below the lid.

[0044] The subregion 5a, 5b of the cover element 5 arranged below the lid 4 after the initial opening can advantageously comprise one or more essentially triangular or curved geometric sections of the cover element 5, cf. the bottom figure of Fig. 2) The cover element 5 is advantageously arranged on the lid 4 and a surrounding surface 9 of the tube head 10 such that, except for the partial region 5a,5b which is concealed after the initial opening, the remaining cover element 5 remains visible to the user after the initial opening.

[0045] The predetermined breaking point 6a, 6b can be formed by perforations and / or indentations in the material of the cover element 5. The predetermined breaking point 6a, 6b advantageously comprises at least one predetermined breaking line, which is arranged to overlap at least partially with the preferably U-shaped circumferential contour 4a of the cover 4. "At least partially overlapping" is advantageously understood to mean that the predetermined breaking line 6a, 6b at least partially crosses the circumferential contour 4a of the cover 4 in plan view.

[0046] The predetermined breaking line 6a, 6b is advantageously arranged such that it extends from a lateral section or end face 7a, 7b of the tube head 10, projecting over the circumferential contour 4a of the cap 4, i.e., projecting into a region of the back of the cap 4b, and back to the lateral section or end face 7a, 7b of the tube head. The predetermined breaking line 6a, 6b can be formed with at least one or more bends, curves, or meanders.

[0047] Fig. 3 and Fig. Figure 4 shows another preferred embodiment of the tube head 10. Here, in Fig. 3 analogous to Fig. Two different views of the tube head 10 are shown before and after the application of the cover element, as well as before and after initial opening. Fig. Figure 4 shows corresponding lateral sectional views of the tube head before (top image) and after initial opening (bottom image).

[0048] According to this embodiment, the tube head 10 and / or the cap 4 can have a recess 12, arranged at least partially below the respective predetermined breaking point 6a, 6b, for at least partially receiving the partial region 5a, 5b of the cover element 5 after initial opening. The recess 12 is advantageously arranged or formed in a transition area between the tube head 10 and the cap 4 and, prior to initial opening, is at least partially spanned by the respective predetermined breaking point 6a, 6b of the cover element 5 in a lateral sectional view.

[0049] This ensures optimized retention of the cover element 5 after initial opening beneath the lid 4 and results in further improved visual confirmation of initial opening. Furthermore, effective initial opening of the cover element 5 is supported because, advantageously, at least in the separation area of ​​the predetermined breaking points 6a, 6b, there is at least partial lack of adhesion to an underlying surface of the lid 4 and / or the tube head 10. Additionally, the cover element 5, in particular the opened or separated sub-regions 5a, 5b, can adhere to a surface 12a of the recess 12 and / or the lid recess 8 after initial opening, advantageously, in particular, by means of an adhesive previously applied over the entire surface of the cover element 5 to bond the cover element 5 to the tube head 10.

[0050] Fig. Figure 4a shows a further preferred embodiment based on the embodiment according to Fig. 3, Fig. 4 in side section view, where the recess 12 differs from Fig. 3, Fig. 4 is provided only in the area of ​​the cover 4. In particular, the cover 4 has a recess 12 arranged at least partially below the respective predetermined breaking point 6a, 6b for at least partially receiving the sub-region 5a, 5b of the cover element 5 after the initial opening. Advantageously, the recess 12 is at least partially spanned by the respective predetermined breaking point 6a, 6b of the cover element 5 in a lateral sectional view before the initial opening.

[0051] Fig. Figure 5 shows several preferred embodiments of the predetermined breaking point 6a, 6b in a top view of the tube head 10. The predetermined breaking points 6a, 6b are preferably located opposite each other on a contour 4a of the lid 4 (see Figure 5). Fig. 2, Fig. 3) aligned. The respective predetermined breaking points 6a, 6b can be uniform or different from each other. The predetermined breaking points 6a, 6b can be zigzag-shaped predetermined breaking lines (see upper left figure), several curved, interlocking predetermined breaking lines (see upper right figure), meander-shaped (see lower right figure), or different from each other (see lower left figure).

[0052] Fig. 6 and Fig. Figure 7 shows two preferred embodiments of a tube head 20 according to the invention, which is an alternative to the preceding embodiments.

[0053] The tube head 20 is designed for attachment to a packaging tube 40. The tube head 20 comprises a shoulder 21 for connection to a packaging tube 40, an outlet opening 22 integrated into the tube head, and a lid 24 connected to the shoulder 21 via a hinge 23 for selectively closing the outlet opening 22. The tube head 20 has a projecting locking element 25, preferably a projecting pin, which is designed to interact with a recess 26 arranged on the lid 24, the recess 26 having an integrated predetermined breaking point 26a to detect initial opening. The recess 26 can be heart-shaped (see figure). Fig. 6), a star-shaped (cf. Fig. 7) or have a parallelogram-shaped geometric form.

[0054] The recess 26 is advantageously formed in a preferably curved edge region 24b of the cover 24, which extends substantially perpendicularly from a preferably end-face arranged rear side 24a of the cover.

[0055] The locking element 25 is advantageously arranged on an end-face surface 21a of the tube shoulder 21, which is covered by the lid when closed. The locking element 25 advantageously extends substantially perpendicular to an axis of rotation of the hinge 23 of the lid 24.

[0056] As in Fig. 8 and Fig. As shown in Figure 9, the predetermined breaking point 26a of the recess 26 is located in a separation area 27 that differs from a contact area 28 of the recess 26, against which the locking element 25 rests in a force-transmitting manner in a closed state of the cover 24.

[0057] The predetermined breaking point 26a is further advantageously arranged in a first plane E1, preferably perpendicular to the main axis L of the tube head 20. The contact area 28 between the snap-in element 25 and the lid 24 is further advantageously arranged in a second plane E2, distinct from the first. The second plane E2 can be arranged parallel to the first plane E1.

[0058] The predetermined breaking point 26a advantageously comprises a thin-walled material web which is arranged between the recess 26 and an outer surface of the cover 29, in particular in the area of ​​a cover engagement 31.

[0059] As in Fig. As shown in Figure 10a and the associated detail view 10b, the locking element 25 advantageously extends essentially in a direction perpendicular to the axis of rotation of the hinge 23.

[0060] In Fig. 11 is a file view of the embodiment according to Fig. 6 shown in the open position, with the cover 24 arranged in a 90° pivoted arrangement.

[0061] As especially in the Fig. 12b,c shown, which is a side sectional view (cf. Fig. As shown in Figure 12a), a distal region 25a of the locking element 25 is preferably at least partially chamfered. In particular, the distal region 25a of the locking element 25 can be chamfered in a barb-like manner in side view (see Figure 12a). Fig. 12b) and / or have a substantially hook-shaped form or edge (cf. Fig. 12c). This creates a force (see force F2) in a horizontal direction towards the tube head 20 and a connected tube 40 when the lid 24 is opened (see force F1), which prevents the locking element 25 from slipping, in particular without breaking the predetermined breaking point 26a.
