专利说明:
The invention relates to a marking system with a marking tape, e.g. on the wrist of a person for the safe identification of the person can be created. Secure identification and identification of persons is required in different areas, e.g. in the healthcare system. This can be done with the help of an identification tape. Such a marking tape is known from WO 99/18 817 A1. The identification band can be printed or described with information in printed and / or data-coded form before it is applied to a person. From this text or the data information can determine the identity of the person. Furthermore, specific personal data such as e.g. the blood type, allergies, drug dependencies, key codes, drug intolerances, group affiliations, etc. are stored and retrieved when needed. Already recorded and data-technically stored personal data can be e.g. by means of commercially available EDP printer and print software on the label tape transfer or print. The text printed on the label tape, or e.g. Information coded as bar code can be read or interpreted visually or technically. In order to create the well-known from WO 99/18 817 A1 identification tape, two parts must be folded, which is somewhat cumbersome. It is easier to handle the labeling tape disclosed in DE 20 2008 004 986 U1. It consists of a flexible composite material and has an elongated basic shape, with a first end and a second end. At the top is a writable and / or printable cover layer made of plastic, below which is an adhesive layer and below it a base layer made of plastic. The base layer does not extend to the second end of the marker tape, with exposed adhesive in the region of the second end of the marker tape covered with a peelable cover. The tag band may be surrounded by a carrier from which it can be released. After removal of the cover, the exposed adhesive allows the identification band placed around the wrist of a person to be quickly and easily glued together to form a ring. However, the production of this identification tape is relatively complex. It is an object of the invention to provide a marking system with an identification band, which can be produced inexpensively and easy to handle. This object is achieved by a marking system having the features of claim 1. Advantageous embodiments of the invention will become apparent from the dependent claims. The inventive marking system has at least one identification band, which has an elongated basic shape with an upper side and a lower side and with a first end and a second end. Furthermore, a carrier is provided with an upper side and a lower side, which laterally surrounds the identification band. The carrier holds the identification tape by means of an adhesive on its underside glued adhesive tape, from which the label strip is removable. The marking tape can be fixed in a closed mold by means of a splice, which is arranged on its upper side in the region of its first end and is preferably covered by a removable cover layer in the delivery state of the marking system. As long as the marking tape is arranged on the carrier, it can e.g. printed or inscribed with a laser printer or a computerized printer using a different technique. In particular, the identification band can be e.g. with prepared data, e.g. the name of a patient, a barcode, etc. as known in the art. Thereafter, the identification tape is removed from the carrier by peeling it from the adhesive film, and e.g. placed around the wrist or ankle of a person to be marked. With the help of the splice, which may still have to be exposed by removing the cover, the identification band is fixed. In this case, a stepless adjustment of the circumference of the identification band is possible in order to make an adaptation, e.g. to allow for the size of the person's wrist. The inventive marking tape can be handled easily and safely. Its production is relatively inexpensive because of the favorable for the production arrangement of the adhesive areas (adhered to the underside adhesive film, splice on the top). As already mentioned, the splice at the top of the marking tape is preferably covered in the delivery state of the marking system of a removable cover layer, e.g. a piece of silicone paper. In advantageous embodiments, the carrier and the identification tape on a common material from which the identification tape is punched along a punching line, wherein the punching line does not penetrate the adhesive film. Because the marker tape is held by the adhesive sheet, the die line can be continuous. However, it is also conceivable that the punching line is interrupted so that short material connections between the marking tape and the carrier remain. The common material of the carrier and the identification tape is preferably designed as a composite material, which has a top side of the identification band and the carrier forming, writable and / or printable cover layer and a base layer. The cover layer and the base layer are connected to each other directly or via at least one intermediate layer, e.g. glued, welded or coextruded, or one of the two layers is applied to the other layer in a viscous form (donated) and solidifies afterwards. Advantageous materials for the cover layer are plastics such as polyester (in particular PET), polyethylene or surface-treated polyethylene (the surface treatment facilitates the printing or labeling). Plastics such as polyester (especially PET) or even soft polypropylene are suitable for the base layer. Particularly suitable is soft PET. If the base layer lying against the skin when using the marking tape is soft, it usually does not interfere with wearing. A harder top layer, on the other hand, makes printing easier and makes the labeling tape less sensitive to damage. The construction of the marking tape as well as the materials used are safe for use on living people. The label tape can be easily attached to a person without health risks. Furthermore, it is stable and durable and insensitive to mechanical and chemical attack, e.g. by water, soap, alcohols or disinfectants. The adhesive film on the underside of the carrier is preferably provided with a pressure-sensitive adhesive, with which it is adhered on the one hand to the underside of the carrier and on the other hand holds the identification tape. As a material for the adhesive sheet is suitable, for. a transparent polyester. But it is also conceivable that the adhesive film, for. Paper as a base material, despite the use of the term "film", which is therefore also explicitly include paper materials. The carrier preferably has a rectangular basic shape, so that it is e.g. easily passable through a printer (also in the form of a tape or fanfold which has a number of sequentially arranged marking systems which are subsequently separated from each other). The adhesive film on the underside of the carrier may have a smaller area than the carrier. In advantageous embodiments of the invention, the bond formed by the adhesive bonding of the marking tape to a closed form is tamper-proof. For this purpose, the marking tape can be provided in the region of the splice with cutting punches, between which only material connections with low tear resistance remain. As a result, a closure is formed which destroys itself in an attempt to release the bond. Because these bodies break in, and the manipulation attempt becomes visually recognizable. The identification band may have a broadening, which preferably begins in the central region of the identification band and preferably extends to the second end of the identification band. If the broadening extends to the second end of the marking tape, it may be provided there with an opening, preferably a transverse to the longitudinal axis of the marking tape slot through which the first end of the marking tape can be passed. The broadening provides a relatively large area that can be printed or labeled with information. If the first end of the marking tape is passed through this slot prior to bonding to a closed mold, the fixation of the two end portions of the marking tape to each other is particularly secure. Embodiments of the identification system are also conceivable in which, in addition to the already described (first) identification band, a second identification band is provided which has an elongated basic shape with an upper side and a lower side and with a first end and a second end. In this case, the second identification band is arranged next to the first identification band on the carrier, which also surrounds the second identification band and holds by means of an adhered to its underside adhesive film (which may be identical to the adhesive film for the first identification band). The second identification band is also provided on its upper side in the region of its first end with a splice and detachable from the adhesive film and fixable by means of the splice in a closed form. The two identification bands may be of the same shape and size, but may also be designed differently (for example, adapted to a baby and his mother so as to be able to confidently associate mother and child with each other). Optionally, the labeling system may have other components, e.g. an identification tag or a label, which are all arranged on the same carrier in the delivery condition and therefore can be jointly printed or labeled. In advantageous embodiments of the invention, a label field is arranged next to the carrier, which has at least one removable from a pad adhesive label. Adhesive labels provided with the label field can be used, for example, for medical documentation and sample labeling. For example, the carrier with the marker tape and label panel may together hold an A4 size sheet which may conveniently be printed by a commercial printer, particularly a laser or ink jet printer, with specific information (also in the form of a bar code, for example). The printing process performed on the entire sheet ensures that both the identification tape and the adhesive labels are printed with associated data so that confusion is largely ruled out. When the adhesive labels are to be used, they are removed from the backing and adhered to an article to be marked, e.g. a sample tube or an index card. If the carrier and the marking tape have a common composite material with cover layer and base layer, as explained above, the cover layer of the material composite may extend beyond the carrier in the label field and form the base material of the at least one adhesive label. The at least one adhesive label is punched out along punching lines of this base material and has an adhesive layer in addition to the base material on its underside. In the production of the marking system, the underside of the base material in the area of the adhesive labels can be provided with a partial glue layer, which forms the adhesive layer and is then covered by the base. As a base is for example a silicone paper. Preferably, a number of adhesive labels is provided, which are separated from each other by cutting punches, wherein the punching lines do not cut through the pad. By vertically stacking punched lines, the adhesive labels can be arranged clearly arranged in several columns and rows, even in different sizes. It may be advantageous if the area occupied by the adhesive labels is still surrounded by an edge, which is also made of the base material and on which the base is glued with its edge region. Embodiments without a peripheral edge are also conceivable. In an advantageous embodiment of the invention, the label field along a perforation line is separable from the carrier, so that if necessary, the label field and the carrier with the identification band can be easily separated from each other, preferably after printing. In the following the invention will be further explained by means of embodiments. The drawings show in<Tb> FIG. 1 <SEP> is a plan view of an embodiment of the marking system according to the invention,<Tb> FIG. 2 <SEP> a longitudinal section through the marking system according to FIG. 1 along the axis L in greatly exaggerated and not to scale representation,<Tb> FIG. 3 <SEP> in the parts 3a to 3e an illustration of different successive steps in the application of the embodiment according to FIG. 1,<Tb> FIG. FIG. 4 shows a plan view of a further embodiment of the marking system according to the invention, which additionally has adhesive labels, and FIG<Tb> FIG. FIG. 5 shows a longitudinal section through the marking system according to FIG. 4 along the axis L in a greatly exaggerated and not to scale representation. In Fig. 1, an embodiment of a marking system 1 is shown in plan view. The marking system 1 includes an identification tape 2 and a carrier 4 surrounding the identification tape 2. The carrier 4 and the marking tape 2 have a common material, the side of which, referred to hereinafter, is designated by the reference numeral 6 and its underside referred to below by the reference numeral 7, see also FIG. 2. In the exemplary embodiment, the carrier 4 is designed rectangular. On the bottom 7, an adhesive film 8 is glued over the entire surface, which is also rectangular, but has a smaller footprint than the carrier 4. In Fig. 1, the periphery of the adhesive film 8 is shown as a dashed line 9. The common material of the carrier 4 and the marking tape 2 is designed in the embodiment as a composite material containing a cover layer 10 and a base layer 12. In the exemplary embodiment, the cover layer 10 consists of a highly durable polyester film of 100 microns thickness. The base layer 12 is designed as a so-called soft-touch film and consists of soft polyester (PET) of 50 microns in thickness. The cover layer 10 gives the identification tape 2 high strength and can be printed or labeled. The base layer 12 is soft and hypoallergenic, so that the identification band 2 practically does not interfere with wear. In the exemplary embodiment, in the production of the composite material, the base layer 12 is applied in liquid form to the cover layer 10 (applied) and then solidifies. The adhesive film 8 is in the embodiment of a 85 micron thick transparent polyester film, which is glued to the underside 7 of the base layer 12 with a pressure-sensitive acrylate adhesive. The marking tape 2 is punched out of the carrier 4 along a circumferential punching line 14. As can be seen in FIG. 2, the punching line 14 does not penetrate the adhesive film 8. Therefore, the adhesive sheet 8 holds the identification tape 2 on the support 4, but the identification tape 2 is easily peeled off from the adhesive sheet 8 (see below) to detach it from the support 4. With its given by the punching line 14 contour, the marking tape 2 extends from a first end 16 to a second end 17. In the region of the first end 16, a splice 20 is provided on the upper side 6 of the marking tape 2 (in FIG. 1 hatched), which is covered by a cover 22 in the delivery state of the marking system 1. In the exemplary embodiment, the cover 22 consists of a silicone paper, which is coated on one side with a transfer adhesive. This transfer adhesive adheres better to the cover layer 10 than to the cover 22 and forms the splice 20. In the production of the marking system 1, the cover 22 is applied together with the transfer adhesive in the region of the first end 16 of the marking tape 2 on the top 6. In the application of the identification system 1 explained below with reference to FIG. 3, the cover 22 can be easily removed, the transfer adhesive remaining on the upper side 6. Instead of an adhesive element based on a transfer adhesive, a double-sided adhesive tape with a one-sided silicone cover can be used for the splice. This tape has a strong adhesive and water-resistant acrylic adhesive. Such a material configuration is particularly appropriate when using the marking tape in the permanent wet area. In the central region of the marking tape 2 begins a broadening 24, which extends to the second end 17 of the marking tape 2. Near the second end 17 is a prepunched slot 26. Further, the identification tape 2 is provided on the upper side 6 in a zone which extends from the central region of the identification tape 2 to the splice 20, with a number of marks 28. In the exemplary embodiment, the labeling system 1 is prepared by first glued to the bottom 7 of the composite material of cover layer 10 and base layer 12, the adhesive film 8 and then the cover 22 is applied to the upper surface 6 with the adhesive 20 forming transfer adhesive. Subsequently, the upper side 6 and possibly also the underside 7 are printed in multiple colors, for example with the markings 28 and other details which are not shown in Fig. 1. Finally, the marking tape 2 is punched along the punching line 14, as well as the slot 26. The punching line 14 also penetrates the splice 20 and the cover 22, but not the adhesive film. 8 Instead of a continuous punching line 14 and a broken punching line is conceivable, remain in the narrow material bridges between the marking tape 2 and the carrier 4. FIG. 3 illustrates an example of the application of the identification system 1 explained with reference to FIGS. 1 and 2. First, the top side 6 of the identification tape 2 is printed with information that is specific to the person who is to wear the identification tape 2. In particular, the widening 24 provides a sufficiently large area. As information, for example, the name of the person or information in coded form, for example, as a barcode, in question. The printing is performed as long as the marker tape 2 is disposed on the support 4, and is performed with, for example, a commercial laser printer. Other types of printers are also conceivable. 3a shows how a user removes the identification band 2 in the region of its second end 17 from the adhesive film 8 attached to the carrier 4. Since the slot 26 as well as the rest of the punching line 14 is punched out only by the cover layer 10 and the base layer 12, but not by the adhesive film 8, the piece of material 30 filling the slot 26 remains on the adhesive film 8. In Fig. 3b is shown how the user after the complete detachment of the marking tape 2 of the adhesive film 8, the cover 22 peels off the splice 20. In the next step, the user places the identification tape 2 around the wrist of a person to be identified and guides the first end 16 of the identification tape 2 with the exposed splice 20 through the slot 26, see Fig. 3c. When the marker tape 2 is tight enough to the person's wrist, the user kinks the marker tape 2 in the region of its first end 16, see Fig. 3d, and finally presses the glue joint 20 against the top 6 of the marker tape 2, see Fig. 3e. The size of the marking tape 2 in its closed form can be adjusted continuously. When determining the size, the markers 28 help. If the adhesive used for the splice 20 adheres to the top 6 very firmly, the marking tape 2 is virtually tamper-proof. That is, in the attempt to pull the splice 20 apart again, the identification tape 2 is so much kinked and damaged that the manipulation attempt is visible. Should it be necessary, the security against impermissible manipulations can be further increased by providing 2 punched punches in the region of the first end 16 of the marking tape, which punches can be introduced, for example, together with the punching line 14 and the pre-cut of the slot 26. Only material connections with a low tear resistance remain between these cutting punches, so that the marking tape 2 enters the region of its first end 16 when it is attempted to release the splice 20. In further embodiments of the marking system, at least one further identification band may be provided on the carrier in addition to the already described marking tape, which is preferably designed similar to the already described labeling tape, but may also have other dimensions. Preferably, a common adhesive sheet is used to hold these marking tapes to the carrier. Other components, for example a removable label from the adhesive film, are also conceivable. In such a marking system, all components can be printed together, as long as they are still arranged on the carrier in order to virtually exclude confusion, for example, in common characterizing persons such as a mother and a baby. Fig. 4 shows an embodiment of the marking system in which, in addition to a marking tape arranged on a carrier, a number of adhesive labels are provided which can be used, for example, for medical documentation and the labeling of samples. This labeling system is denoted by l. The support 4 with the marking tape 2 is designed in virtually the same way as in the embodiment according to FIGS. 1 to 3, which is why in this area of the identification system l the same reference numerals are used as in the marking system 1. As explained above, show the carrier 4 and the marking tape 2 on a composite material with a cover layer 10 and a base layer. In the embodiment according to FIG. 4, the cover layer 10 has a thickness of 50 μm and the base layer likewise has a thickness of 50 μm. Next to the carrier 4, a label field 50 is arranged, on which in the exemplary embodiment two rows of four larger adhesive labels 52 and four rows of each of seven smaller adhesive labels 53 are provided. An edge 54 surrounds the adhesive labels 52, 53. In the exemplary embodiment, the carrier 4 with the identification tape 2 and the label field 50 together take a sheet in A4 format, which is convenient with a commercial printer, in particular a laser or inkjet printer, with specific Information (also in the form of a barcode, for example) can be printed. The adhesive labels 52, 53 and the edge 54 are made in the embodiment of the material of the cover layer 10 of the carrier 4 and the marking tape 2, which thus forms the base material of the adhesive labels 52, 53 and is also designated 10. In the production of the marking system 1, the underside of the base material 10 in the region of the adhesive labels 52, 53 and a part of the edge 54 is coated with an adhesive 55 (eg an acrylate adhesive), which is covered with a support 56 (eg made of silicone paper), see the longitudinal section of the marking system 1 along the axis L shown in FIG. In Fig. 4, the position of the base 56 is indicated by a dashed line. The adhesive 55 adheres better to the underside of the base material 10 (ie, the underside of the adhesive labels 52, 53) than to the base 56. Therefore, the adhesive labels 52, 53 are easily peeled off the base 56 and adhered to a desired location , The adhesive labels 52, 53 are separated from one another and from the edge 54 by vertical punch lines 58 and 59 which penetrate the base material 10, but not the base 56. In the exemplary embodiment, the label field 50 along a perforation line 60 is separable from the carrier 4, so that if necessary, the label field 50 and the carrier 4 with the identification band 2 can be easily separated from each other, preferably after printing.
