The spacers are joined to the base layer via the self-adhering coating.

Description

The present invention relates to a label for Übersiegeln a transition between axially different cross-sections, as well as a coaxial arrangement of two separable body whose transition is sealed with such a label.

An example of the Übersiegelung a transition between axially different cross-sections is the sealing of a container with a cap with respect to the rest of the container different outer diameter. Another example is the sealing of a syringe assembly having a syringe body and a protective cap attached to the syringe body. The latter often has a much smaller circumference than the syringe body.

By the seal must be ensured that the syringe assembly remains closed until it is used by means of the protective cap, or that it can be seen from an intact seal that the syringe assembly has remained closed so far. If the seal is damaged, however, this is an indication that the cap could have been opened in the meantime. The syringe assembly must then no longer be used because the concealed by the cap needle could be contaminated or even a manipulation of the filling of the syringe body may have occurred.

With simple, strip-shaped, self-adhesive labels, such a seal is basically not wrinkle-free. In addition, there is the problem that conventional labels by means of a conventional dispensing device due to the large Diameter difference can not be raised so that they rest on both bodies, ie syringe body and protective cap. For labeling machines can not reach the area below the syringe body.

As an alternative in the cases mentioned, the seal would generally be provided with a shrink label (sleeve label), which is pulled in a tube over the transition to be sealed and then shrunk under the action of heat. In this case, the geometry of the label adjusts itself by the shrink film, of which it consists, contracts as far as it allows the predetermined geometry of the body to be sealed.

However, sealing by shrink label can be problematic. On the one hand, one is severely restricted in the selection of materials, since only films with corresponding shrinkage properties come into question. On the other hand there is the problem with labeled labels that the font warps ugly due to the shrinkage. In the case of containers with pharmaceutical content, in particular syringe bodies with active ingredient-containing infusion solutions, the seal by means of shrink label often already prohibits due to the heat required to trigger the shrinking process, since many active pharmaceutical ingredients are extremely sensitive to heat.

The present invention is in view of the above-described problem, the object of providing a label for safely sealing a transition between axially different cross-sections, in particular the transition between a syringe body and an associated cap to create, which can be applied without heat and yet wrinkle-free. Furthermore, the machine dispensing should be possible.

Further, the present invention seeks to provide a coaxial arrangement of two separable body with cylindrical and / or prismatic areas, wherein the body in the region of their transition to each other have different cross-sections, in particular a syringe body and protective cap having arrangement to provide which a secure seal having the transition between the bodies.

The term cylindrical and / or prismatic below also refers to these shapes approximate geometries, i. essentially all bodies with at least partially axially parallel generatrices.

According to one aspect of the invention, the object is achieved by a label according to claim 1. Preferably, the label is designed for tangential dispensing. Advantageous embodiments of the invention may be designed according to one of claims 2-18.

The spacer or the preferably provided plurality of spacers advantageously at least partially equalize the cross-sectional difference of the bodies, but are preferably dimensioned so that they rest on the body with the smaller cross-section in the region of the transition when the label is attached as intended.

A sealing effect can be advantageously achieved by proper attachment of the label, that the spacers are adhesive side underside and therefore with that body with the smaller cross-section in the transition area. Furthermore, a sealing effect can advantageously also be achieved in that the spacers in normal use with a projection, such as a protruding edge, or a depression on the body with the smaller cross-section in the transition area are engaged.

To improve a defined unsealing advantageously differently arranged perforation and / or punching lines, tear threads and the like can be provided more.

An advantageous alternative to the use of multiple spacers is the use of a single wide spacer with a large width (in the dispensing direction), which is preferably notched one or more times transverse to the dispensing direction in order to follow the bending of the surface of the body to be sealed.

Advantageously, a part of the preferably provided gripping tab can be designed to be slightly adhesive or non-adhesive, so that a gripping area results for unsealing. This can also be achieved in the case of self-overlapping adhesive bonding, in that the region of the label on which the flap comes to rest as intended is coated in adhesive-repellent manner.

As materials for the base layer, in principle, the most common film materials in question, in particular conventional plastic films, with one and multi-layer designs are conceivable. An execution of a base layer of paper is possible.

When selecting suitable adhesives, it is possible to resort to adhesives customary in the field of conventional labels, in particular pressure-sensitive adhesives

Also for the spacers a variety of materials are advantageously used. The choice of material is usually made taking into account the diameter difference to be bridged. Especially with large diameter differences at the transition, the choice of a foam may be advantageous. For many materials, it is beneficial to attach the spacer to the base layer by means of the pressure-sensitive adhesive layer on the base layer.

It is particularly advantageous to design the spacer or spacers in the form of a continuous or interrupted intumescent layer, ie a layer of foamable material. This can also be glued to the base layer, or applied by printing directly to the base layer or the pressure-sensitive adhesive coating of the base layer. In particular so-called intumescent paints are suitable for printing as an intumescent layer. Intumescent colors are commercially available under the English term "Puff Ink". Furthermore, additives are offered by various manufacturers under the terms "puff additives" or "puffing agent", to which conventional (in particular screen) printing inks can be added in order to make them foamable, ie to intumescent in the sense of the present invention.

The foaming can either be done by the label manufacturer or by dispensing, i. shortly before, shortly afterwards or during the dispensing. Foaming during dispensing has the advantage that label webs, i. Webs from Abziehmaterial on which labels are generally arranged usually during transport and storage, are better rolled up, as if the labels in the area of spacers are already greatly raised especially when foaming after the actual dispensing process, the latter is probably greatly simplified in the rule.

Furthermore, the pressurized application of an intumescent layer eliminates the sometimes difficult subdivisions, so that this results in a simplification of the production.

The foaming process is usually induced by the action of heat, but in principle it is also conceivable to use different foaming material systems. Depending on the application, the heat can be effected, for example, by microwaves, in the heat chamber or by heat radiation. By laser-absorbing components in the intumescent or a possibly additionally provided, laser radiation absorbing layer, the heat required for foaming can be specifically introduced locally by means of laser without causing unwanted heating of one of the body to be sealed or its contents.

In the embodiment according to claim 16 is a particularly advantageous embodiment of the present invention. The leading part of the label is, for example by means of a dispensing machine, on those of the body to be sealed with the larger cross section in the region of the transition, for example, the syringe body, aufspendbar. With regard to the intended use, the dimensions of the label are chosen such that during further dispensing the follower partially overlaps the leader in the manner of so-called overlapping labeling, but axially in the direction of the body to be oversized with the smaller cross section in the region of the transition survives. In the projecting (ie offset in the transverse direction to the dispensing relative to the lead part) region of the trailing part, the spacer or preferably a plurality of spacers are arranged on the underside of the label.

According to a further preferred embodiment, the label is not forked over most of its extension in the dispensing direction, i. running continuously in the direction transverse to the dispensing direction

According to a further aspect of the invention, the object is achieved by an arrangement according to claim 19. Advantageous embodiments of the invention may be designed according to one of claims 20-26.

The syringe arrangement shown in FIG. 1 has a syringe body 100 with a syringe needle 101, which is covered by the protective cap 102 arranged coaxially with the syringe body 100 with an annular projection 103. Not shown is the syringe plunger. Hidden lines are only partially shown and indicated by dashed lines. Such an arrangement is illustrated by over-sealing the transition between syringe body 100 and protective cap 102 with a label according to the invention to an inventive arrangement, as shown in Fig. 2a.

In FIG. 2a, the syringe arrangement from FIG. 1 is indicated by dashed lines (with a long dash) for the sake of clarity. Hidden lines are indicated by dashed lines with a short dash.

A label according to the invention with a base layer 3 having a leading part 1 and a trailing part 2 and six spacers 4 is partially applied to the syringe assembly. For the finished affixing of the label, the left half of the trailing part 2, which is left in the illustration, is still adhered to the syringe body 100, wherein the trailing part 2 partially overlaps the leading part 1. Once the label has been glued on, the spacers 4 are distributed uniformly over the circumference of the protective cap 102. The spacers 4 are on the underside of the base layer 3 in the staggered portion 1 of the trailing part 2 by means of the pressure-sensitive adhesive coating (not shown in Fig. 2a-d), which also ensures the adhesion between the base layer 3 and syringe body 100. The spacers 4 may also be coated on the underside with pressure-sensitive adhesive; However, this is not necessary in the illustrated embodiment, since the spacers 4 prevent the removal of the cap 102 already due to the geometry of the arrangement,

The detailed illustration in FIG. 2b, in which only three spacers 4 and the protective cap 102 are shown, shows how the spacers 4 are in engagement with the annular projection 103 of the protective cap 102. In order to remove the protective cap 102 from the syringe body 100, the spacers 4 must be removed from their position. This is possible according to the invention only with destruction of the label. This can be realized in different ways. For example, a perforation may be provided (see embodiment of Fig. 4), which allows a tearing of that part of the label on which the spacers 4 are arranged. Alternatively, provisions may be made which allow shearing of the individual spacers 4 near the base layer 3. Conceivable, for example, a multilayer design of the base layer 3 with a slightly shearing lower layer or conventional measures for a reduced adhesive force of the pressure-sensitive adhesive coating between spacers 4 and base layer 3. A destruction of the label in the manner described or otherwise indicates the seal breakage.

Fig. 2c serves to illustrate Fig. 2a, in which the base layer 3 is shown omitting all other components of the arrangement. Fig. 2d shows the label in a plan view in plan view, wherein the position of the spacers 4 is indicated by dashed lines.

3a shows in a planar representation of an inventive label with a Voidfolienaufbau 5 in the region of the trailing part 2. When appropriate attachment of the trailing part 2 overlaps with his Voidfolienaufbau 5 the leader 1. Both trailing part 2 and supply part 1 therefore have a length which in the area the extent of that of the body to be sealed with the larger one Cross section is. The position of the spacers 4 in the staggered portion 1 of the trailing part 3 is indicated by dashed lines. In the area of the leader 1, the label is provided with an imprint 6.

Fig. 3b-c show sectional views of the label of Fig. 3a, and indeed Fig. 3b in the direction indicated by the dashed line AA 'sectional plane, Fig. 3c in the direction indicated by the dashed line BB' sectional plane, and Fig. 3d in which by Dash line CC 'indicated cutting plane.

The void film assembly 5 can be made as conventional, well-known void films. An example of a suitable void film construction can be seen in FIG. 3c. There is a color layer 7 on the underside of the self-adhesive coating 8, which also serves to attach the base layer 3 on the body to be sealed with the larger cross-section and the attachment of the spacers 4 on the base layer 3. The ink layer 7 is connected via a bonding agent 9 with a piece of film 10, which has an adhesive layer 11 on the underside. Locally the adhesion between ink layer 7 and film piece 10 is reduced by adhesion reducer 12. Otherwise, the adhesion of the ink layer 7 to the film piece 10 (via the adhesion promoter 9) is greater than the adhesion between the color layer 7 and the self-adhesive coating 8.

When intended self-overlapping attachment of the label, the adhesive layer 11 adheres to the top of the lead part 1. Attempting to deduct the trailing part 2 from the leader 1, so separates the Voidfolienaufbau 5 such that the ink layer 7 is subtracted in the region of Adhäsionsverminderer 12, the rest Regions of the ink layer 7, however, remain with the film piece 10 on the second leader part 1. Since the base layer 3 of the label is transparent at least in the region of the void film structure 5, adhering parts of the ink layer 7 are clearly recognizable on the trailing part 2. With a suitable arrangement of the adhesion reducer 12, the parts of the ink layer 7 which adhere to the supply part 2 form a characteristic pattern or a characteristic lettering 13 which irreversibly indicates the seal breakage. As long as the seal is unhurt, the lettering 13 is not visible.

A transparent trailing part 2 with an otherwise non-transparent label can be achieved, for example, by stamping the label from the continuous transparent base layer 3, which is printed with an opaque layer 14, except in the region of the trailing part 2.

The underside adhesive coating 14 of the spacers 4 may be dispensable (for example when mounted on an arrangement according to FIG. 1).

To facilitate removal of the trailing part 2 during the intended opening of the seal the trailing part 2 is a gripping tab 15 is formed, which is free of adhesive on its underside or has a reduced adhesive force.

Figure 4 shows a similarly designed according to the invention label, wherein instead of a Voidaufbaus 5 a perforation 17 is provided to indicate a seal breakage. The attachment is again analogous to Fig. 2a-c. By further perforation lines 19 separable portions of the trailer part 2 are designed as slip sections 16, which can be archived after separation for documentation purposes. Upon proper self-overlapping attachment of the label, the document sections 16 come to lie on a siliconized or otherwise adhesive repellent coated portion 20 of the leader 1 to be easier to remove without damaging the remaining label or seal. Local recesses 18 in the lower-side pressure-sensitive adhesive coating (not shown in FIG. 4) can serve as gripping areas for the receipt sections 16.

In Fig. 5 a particularly simple and inexpensive embodiment of the present invention is shown. The base layer 3 of the label is dimensioned such that it does not overlap itself when properly applied to that of the body to be sealed with the larger cross section in the transition area, but extends approximately over the entire circumference of said body, so that the spacers. 4 are arranged approximately uniformly over the circumference of the other, coaxially arranged body. The sealing effect is as described above. A perforation line 17 destroys the label when the seal is opened.

Fig. 6a shows a sectional view similar to Fig. 3d by an Ettikett whose spacers 4 are made of a foamable material, which, however, may be constructed as the label shown in Fig. 3a-d otherwise. Fig. 6b shows the same illustration, but after foaming. The spacers 4 are applied by means of the pressure-sensitive adhesive layer 8 on the base layer 3 and in turn provided on the underside with a pressure-sensitive adhesive coating 11.

FIGS. 7a and 7b show analogous dart positions of a similarly structured label, but in contrast to FIGS. 6a and 6b, the spacers 4 are applied directly to the base layer 3 in the form of an interrupted intumescent color layer by printing technology. The pressure-sensitive adhesive layer 8 is applied continuously prior to sticking in essentially one operation on base layer 3 and Intumeszenzfarbschicht. The intumescent paint contains components which absorb radiation (in practice, preferably laser radiation) of a specific wavelength range, so that a targeted local heat input is possible to initiate the foaming process.

Fig. 8a again shows a similar structure as Fig. 7a, however, the spacer 4 forming Intumeszenzfarbschicht is executed throughout, and the pressure-sensitive adhesive layer (not shown in Fig. 8a-d) is located only on the not provided with intumescent underside face of the base layer third

The arrangement shown in FIG. 8b with a greatly exaggerated wall corresponds approximately to the syringe arrangement from FIG. 1. It is a section in the area of the protective cap 102 with a sectional plane parallel to the longitudinal axis of the syringe arrangement. Visible are the out-of-plane walls of the syringe body 100 and the edge 103 of the protective cap 102. Not shown is the syringe needle.

Fig. 8c shows the arrangement of Fig. 8b in the same sectional plane, but after applying the label shown in Fig. 8b. After foaming, the spacer 4 is in engagement with the edge 103 of the protective cap 102, as can be seen in FIG. 8d with reference to the hidden outer contour of the edge 103 shown in dashed lines. As a result, an effective seal is achieved.
