EP1555644A1 - Label for sealing a junction between axially different cross sections - Google Patents

Abstract

The label has two at least partly self-adhesive strip parts (1,2) that are separated from each other over most of their length and that are continued in a common base part (5). When the label is laid out in flat form the longitudinal edges (10,10b) of the first strip part (1) are at least partly curved. An independent claim is also included for a container with an inventive label.

Description

The present invention relates to a label for over-sealing a transition between axially different cross sections, in particular a label for over-sealing a cylindrical-conical transition, further comprising a container which has such a Label has. By over-sealing a transition between axially different Cross-sections is understood that two coaxially arranged body with each other are sealed, whose cross-sections in perpendicular to the common axis standing levels to partially deviate from each other.

Labels of the type mentioned are used, for example, if a in substantially cylindrical container with a conical container closure or to be sealed to the conical part of a container closure.

With simple, strip-shaped, self-adhesive labels with naturally in essential rectangular shape is basically not such a seal wrinkle-free possible. In particular, at the transition between the cylindrical part and the conical closure part, but also on the conical closure part form due to the change in diameter disturbing wrinkles and kinks. The problem strengthens when at the transition between cylinder and cone Diameter jump, i. there is a step-like taper in the axial direction.

A similar problem already occurs when a diameter jump between two cylinders, for example in a cylindrical container, its likewise cylindrical cap a slightly larger or smaller diameter than the rest of the container.

As an alternative in the cases mentioned, the seal would always be included a shrink label (sleeve label), which tubular over the zu pulled over the transitory transition and then under heat is shrunk. The geometry of the label adjusts itself by the Shrink film, of which it consists, contracts as far as it Container geometry allowed.

However, sealing by shrink label can be problematic. On the one hand one is strongly restricted in the material selection, since only foils with corresponding shrinkage properties come into question. On the other hand there is Labels labeled the problem that the font due to shrinkage unpleasant. For containers with pharmaceutical content prohibits the Seal by means of shrink label already often due to the release of the Shrinking required heat effect, since many drugs strong are sensitive to heat.

The present invention is in view of the above problems The object is to provide a label for sealing a transition between axially different cross sections, in particular the transition between a cylindrical container and its conical closure part to create, which without Heat and yet wrinkle-free can be applied.

This object is achieved according to an aspect of the invention by a label for Sealing a transition between axially different cross sections, which two over the vast majority of their length separated from each other next to each other in a common base part continuing, at least partially sebstklebende strip parts, solved.

Wrinkling is avoided by removing strip parts over the majority Their length by a cut or a punching are separated from each other, so that each strip part can individually follow a different form of backing.

The common base part represents the connection between the two strip parts and thus ensures the function of Übersiegelns.

Due to the self-adhesive design, which by means of at least part of the surface of the Bottom of the label provided pressure-sensitive adhesive layer must be achieved In contrast to a shrink label, applying no heat introduced become. The analog readability of preferably provided imprints or Labels, does not change when applying, because no distortion due to Wrinkling or shrinkage occur. Barcodes (Pharmacodes) stay in fully functional, so machine by scanner readable.

In the case of Übersiegelns a cylindrical-conical transition, it is special advantageous if the longitudinal edges of the first strip part, which at intended use on conical surface rises, at least Sectionally arcuate when the label is just spread. Under arcuate is in connection with the present invention, in particular the Understood form of a partial circle, but also approximations to this form, for example, by polygons. Preferably, the longitudinal edges of the second run Strip portion at least partially rectilinear parallel, so that at least partially arcuately extending longitudinal edges of the first strip part a widening gap between the first and second strip part exists, and the Label has a bifurcated shape. The first, in essentially rectangular, Streifenteil then corresponds geometrically in about the settlement of a part of a Kegelmantels, the second strip part of the settlement of a part of a Cylinder jacket. Due to the gap between the first and second strip part leave Thus, not only wrinkle-free, the first strip part on a conical surface and glue the second strip part onto a coaxially adjacent cylindrical base, but it is also achieved a good donation.

According to a particularly preferred embodiment, in the base part a Schwächungsline provided, which between the continuation of the first Streifenteils forming area and the continuation of the second strip part forming region of the base part is arranged. The weakening line is preferably as perforation line or as one or more punches resp. stampings educated. If the label is attached in accordance with the order, then the Line of weakness where the two zusammenzusiegelnden body, ie for example, cylindrical container body and conical cap, abut. Become the two sealed bodies of each other separated, the label tears along the line of weakness, and through the label thus caused sealing is clearly broken open. Due to the defined tear along the line of weakness is the continuation of the first portion forming portion of the base part after the seal break on the a body, and the continuation of the second strip part forming region of Base part on the other body. Furthermore, the unsealing, depending on the design of the Labels can also be achieved by removing one of the strip parts so far until the base part breaks along the line of weakness.

Insists on the transition between the two bodies sealed together Diameter jump, i. a step-like rejuvenation, so prevents one preferably provided additional film layer, which exclusively in the Continuation of the portion forming a strip portion of the base part is arranged, as Height compensation the formation of kinks and folds in the area of the base part. This Height compensation is thus advantageously arranged in the region of the base part, the intended use of the label on the body with a lesser Diameter rests.

According to a particularly preferred embodiment, a strip part has a protruding tab on the side facing the other strip part. Preferably, this tab is at the end or. near the opposite of the base part remote end of the corresponding strip part arranged. Is the tab self-adhesive, it provides for a proper attachment for a additional sealing.

Preferably, at the point where the tab of one strip portion is on the other Strips part or its continuation rests, provided a Voidfolienaufbau, i. one multilayer, a color layer having film structure with local different adhesion between the color layer and adjacent Film layers. Due to the locally different detachment behavior remain so Peel off the tab parts of the paint layer on the strip part (or on its Continued) on which the tab was glued, and other parts of the Color coat on the tab itself. By appropriate arrangement of the local different adherent areas results in a characteristic, the seal break indicating pattern or a characteristic indicating the seal breakage Lettering. Before sticking, the void film assembly can either be on the tab or be arranged on the area on which the tab according to the Use comes to lie. In principle, a variant is also conceivable in which individual layers of void film construction on the flap and other layers of the film Voidfolienaufbau are arranged on the corresponding counterpart, so that the Voidfolienaufbauerstbeim the proper sticking of the label arises.

Advantageously, a portion of the tab may be low tack or non-stick be executed, so that there is a Anfaßbereich for unsealing. This can too be achieved in that a part of the area on which the tab is intended to lie, is coated adhesive repellent.

In general, if the unsealing is done by one of the strip parts until the base part is at the transition of the body to be sealed tears, a weak adhesive grip area provided on the corresponding strip part be.

In principle, most of the materials used for the label according to the invention common film materials in question, in particular conventional plastic films, wherein einund multilayer designs are conceivable. Also when selecting suitable adhesives can be applied to the usual in the field of conventional labels adhesives, in particular Pressure-sensitive adhesives, are used.

As already indicated, according to another aspect of the invention, the underlying task by a container with a closure member with, at Consider coaxial planes, from the rest of the container at least partially deviating cross section and solved with a label of the type described above, wherein the first strip part with the closure part and the second strip part with the remaining container or. a part of it is glued. The label can advantageously be designed as described above.

According to a particularly preferred embodiment, the dimensions of Container or its closure part and the label so matched to each other, that over-round labeling is achieved. That means the length of the respective strip portion plus the length of its continuation forming region of the strip Base part are larger than the circumference of the corresponding Behäterteils, so that the Label itself overlaps. The overlap can be in the range of one or in the range Both strip parts occur.

Such a round-robin design offers the advantage of a safer hold a surface finish of the container or its closure part, which no optimal adhesion conditions for the self-adhesive coating of the label offers. Furthermore, the Überrundum-labeling is the entire Behälterum catch as an information surface, i. for imprints, labels and the like Available.

Fig. 7

shows a sectional view of the label shown in Fig. 4 along the kinking section line A-A'-A ".

The label shown in Fig. 1 is for over-sealing the transition between the Cap 3 and the container body 4 of the container shown in Fig. 2 certainly. Cap 3 and container body 4 are substantially cylindrical, However, the outer diameter of the cap 3 is slightly larger than that Outer diameter of the container body 4.

The strip parts 1 and 2 are by a punching line 6, which for each of the Strip parts 1, 2 defines a longitudinal edge, over most of its length separated and continue in a common base part 5. By the Separation of the strip parts 1, 2, these can the different circumferential contours the cap 3 and the container body 4 follow without kinks arise. Both strip parts 1, 2, preferably also the base part 5 are at least part-surface coated on the underside with pressure-sensitive adhesive. Because of the connection between the two Strip parts 1, 2, which is formed by the common base part 5, the Sealing function, i. with glued label, as shown in FIG. 3 shown, can cap 3 and container body 4 only destroy the label in the region of the base part 5 from each other. To the label at the seal break defined to be tear, is a line of weakness in the form of a perforation line 7 is provided, which is between the continuation of the first strip part forming area 5a and the continuation of the second strip part forming Area 5b of the base part 5 is located and thus to some extent the continuation of Punching line 6 forms.

To compensate for the difference in diameter between cap 3 and Container body 4 is in the continuation of the second strip portion forming region 5b of the base part 5 on the underside an additional film layer 8 angeordent, which in Fig. 1 and FIG. 3 is indicated by a hatched hatching. This is also for the base part 5 a wrinkle-free dispensing possible.

The common length of the first strip part 1 and its continuation forming Area 5a is slightly larger than the circumference of the cap 3, as is the common length of the second strip part 2 and its continuation forming Area 5b slightly larger than the circumference of the container body 4, so that in each case a self-overlapping arrangement of the label on the respective container part 3, 4th results, as shown in Fig. 3 dargestelt. Thus, a secure hold is guaranteed even then if the surfaces of the cap 3 and the container body 4 are not ideal Form adhesive conditions for the self-adhesive coating of the label.

In Fig. 4, a suitable for the sealing of the container shown in Fig. 5 is suitable Label shown. Fig. 6 shows the container in accordance with the invention sealed state. In Fig. 7 is a section through the label of Fig. 4 along the kinking Section line A-A '-A "shown.

The container is one for infusion or Injection liquids used container body 4 with a closure 3, which a conical closure member 3a and a cylindrical closure member 3b identifies. to Removal of the container contents of the conical closure member 3a is removed. The biggest Taper diameter of the conical closure member 3a is slightly smaller than that Cylinder diameter of the cylindrical closure member 3b. To over-seal is the Transition between conical closure member 3a and cylindrical closure member 3b.

The first strip part 1 is from the second strip part 2 over most of its length separated by the widening gap 9. The longitudinal edges 10a, 10b of the first, for the conical closure member 3a certain strip portion 1 are (in the same expanded state) arcuately curved and approximately in the form concentric circular arcs. Som it has the first strip portion 1 in the shape approximately the settlement of a truncated cone, i. the shape of the settlement of part of the Mantels of the conical closure member 3a. The longitudinal edges 11a, 11b of the second, for the cylindrical closure member 3b certain strip part 2 are (in the same spread state) in a straight line parallel. Thus, the second strip part 2 has in such as the shape of the development of a cylinder, i. the shape of the settlement of a Part of the shell of the cylindrical closure member 3b.

By separating the strip part 1, 2 and their different shape can this the different circumferential contours of the conical closure member 3a and the cylindrical closure member 3b follow without wrinkles arise, as shown in Fig. 6 shown. The inner longitudinal edges 10b, 11a of the strip parts 1, 2 lie in glued state directly next to each other, though by virtue of the different diameter at the transition formed step offset from each other.

Both strip parts 1, 2 continue in the common base part 5 and have (As preferably also the base part 5) at least part of the underside of a side surface self-adhesive coating 12 (see Fig. 7). Because of the connection between two strip parts 1, 2, which is formed by the common base part 5, the sealing function is ensured, i. with the label affixed, as in FIG. 6 shown, the closure parts 3 a, 3 b can only with destruction of the label in Separate area of the base part 5 from each other. To the label at the seal break defined to be tear, is a line of weakness in the form of a perforation line 7 is provided, which is between the continuation of the first strip part forming area 5a and the continuation of the second strip part forming Area 5b of the base part 5 is located and thus to some extent the continuation of Gap 9 forms.

The discontinuous change in diameter at the transition between conical Closure part 3a and cylindrical Verschlüßteil 3b is by, in turn underside coated with pressure-sensitive adhesive 21, additional film layer 8 in the Continuation of the first strip part 1 forming region 5a of the base part. 5 balanced. Thus, the dispensing can also in the area of the base part 5 wrinkle-free respectively. For serving as height compensation additional film layer 8 is suitable especially a soft foam material, especially if larger Diameter differences are to be bleached.

In principle, the procedure can be as follows: The underside coated with pressure-sensitive adhesive 21, additional film layer 8 is on a support Abziehmaterial arranged. There is a punching and grid deduction to the Extension of the film layer 8 on the later continuation of the first strip part. 1 to define forming region 5a of the base part 5. Subsequently, a the Base layer 19 of the label forming plastic film, for example a Polyethylene film, with self-adhesive coating 12 on the underside laminating continuous web before the fork-shaped contour of the label from the Overall composite is punched out.

On its side facing the second strip part 2, the first strip part 1 a tab 13, which on the base part 5 opposite end of the first Strip part 1 is arranged. When properly pasted label is the Lasche 13 via a Voidfoleinaufbau with the continuation of the second Strip part 2 forming portion 5b of the base part 5 glued. This will be done achieved that the second strip part 2 with the continuation forming region 5b of the base part 5 has a common length which is equal to or slightly less than the circumference of the cylindrical closure part 3b is, whereas the first strip part 1 is long enough to the area forming its continuation 5a of the base part 5 overlap.

Alternatively, the second strip part 2 may be made so long that he his Continued overlapping area 5b of the base part 5 overlaps. In this case, the Tab 13 with the overlapping region of the second strip part 2 glued.

The void film construction can be carried out as conventional, well-known Voidfolien. An example of a suitable void film construction is shown in FIG. in the Area of the tab 13 is a color layer 14 on the underside of self-adhesive coating 12. This color layer 14 is via a bonding agent 15 connected to a piece of film 16, which underside an adhesive layer 18th having. Locally, the adhesion between the color layer 14 and piece of film 16 by Adhesion reducer 17 reduced. There, the color layer 14 adheres more strongly to the self-adhesive coating 12 as on the piece of film 16. Otherwise, the liability the color layer 14 on the film piece 16 (via the Haftvermlittler 15) stronger than the adhesion between paint layer 14 and self-adhesive coating 12.

Is the tab 13 on the adhesive layer 18 on the second strip part 2 or whose continuation forming portion 5b of the base member 5 adhered, and trying one to peel off the tab, the Voidfolienaufbau separates so that the Color layer 14 is removed in the region of the adhesion reducer 17, the remaining portions of the ink layer 14 but with the film piece 16 on the second Strip part 2 or on the continuation forming region 5b of the base part. 5 remain. Since the base layer 19 of the label at least in the region of the tab 13th is transparent, the adhering to the tab 13 parts of the ink layer 14 are clear recognizable. With an appropriate arrangement of Adhäsionsverminderer 17 form the on the tab 13 adhering parts of the color layer 14 a characteristic pattern or a characteristic lettering 20 that irreversibly indicates the seal breakage. As long as the seal is not injured, the lettering 20 is not visible.

A transparent tab 13 with otherwise non-transparent label can be for Achieve example by making the label from the continuous transparent Base layer 19 is punched, which except in the region of the flap 13 with an opaque Layer 22 is printed.
