Definitions

  • the invention relates to a security bag made of preferably environmentally friendly polyethylene or polypropylene with an irreversible security closure system according to the preamble of patent claim 1.
  • Such an irreversible security closure system is, for example, with the subject of EP 0 773 889 B1 known. It is a tamper-evident tape and a matching closure.
  • the purpose of the measures is to provide a closable with an adhesive tape closure bag whose unauthorized opening is readily apparent.
  • the cited document provides that the adhesive can only be dissolved under high temperatures, and if such an opening attempt takes place at high temperatures, a thermochromic layer should indicate the unauthorized opening.
  • thermochromic ink composition which has a special thermochromic ink composition, but which is unable to verify the originality of the thermochromic color change.
  • a marking carrier has become known, in particular in the form of a data memory card, with at least one marking overprint, wherein at least in some areas a color layer is provided whose hue irreversibly changes when exposed to heat.
  • a color layer is provided whose hue irreversibly changes when exposed to heat.
  • two different colors can be used for the color layer, which have two different temperature points for the color change, such as 10 ° C and 35 ° C, at which the colors become opaque.
  • the invention is therefore based on the object, starting from the EP 0 773 889 B1 develop a tamper-evident tape and a corresponding closure so that after the occurrence of the thermochromic color change and the originality of the display element can be checked.
  • An essential feature of the invention is that now provided according to the invention that an irreversible color change takes place in a first phase of heating and preferably in a temperature range below 90 ° and greater than the room temperature.
  • thermochromic security element is also stable against chemical attack.
  • it is stable to solvents, and can not be attacked and dissolved by the solvents mentioned.
  • This also serves to secure the security element, because it is therefore stable against chemical attack and if a chemical attack with a chemochromic color change, so that an attack with the chemical solvents readily recognizable.
  • thermochromic usable irreversible color change is additionally assigned a chemochromic color change.
  • thermochromic change of color when exposed to heat and checking an irreversible color change in case of chemical attack on the security strip further improves the safety effect of this security strip.
  • the security strip is protected against thermal attack and against chemical attack and hardened and therefore meets the highest security requirements.
  • the originality can be checked in both cases.
  • a security bag 1 which preferably consists of a polyethylene, polypropylene, and the like, environmentally friendly plastic materials. It has an exemplary thickness of z. B. 20 to 200 .mu.m, in particular 30 to 80 microns.
  • the wearing style is similar to a conventional grocery bag, as it is sold in conventional self-service stores on a large scale.
  • the security pocket is opened in its upper area and forms a back 2 and a front 3 opposite.
  • a security closure system 4 is provided, which in the embodiment shown consists of a security closure band 5, which is provided on the inside with an adhesive layer 6.
  • the peel-off film 7 has non-stick properties and consists for. B. from a siliconized paper or the like.
  • the adhesive region of the release liner 7 is therefore also coated with the adhesive layer 6.
  • the adhesive layer 6 can be colored in any way, for. B. may have a blue hue.
  • the security fastener tape 5 may have a different color than, for example, the color of the security pocket 1 with the backs 2 and the front side 3.
  • a printing can also be provided.
  • the printing is then visible from the outside through the security fastener tape 5.
  • thermochromic security feature 10 is arranged, which narrow rectangular structure extends for example over the entire width of the security pocket 1.
  • thermochromic security feature 10 is applied by pressure through any printing process, in particular by flexographic printing or other means.
  • the area 11 extends over the entire width of the security pocket. 1
  • thermochromic security material 10 in the area 11 is now exactly opposite to the adhesion region 8 of the release liner 7 and that when the release liner 7 is peeled off, the adhesive layer 6 now comes into direct contact with the thermochromic security feature 10 and irreversibly covers it ,
  • thermochromic security feature 10 has an irreversible color change, either from the outside on the back 2 of the security pocket 1 or from the opposite side through the Safety closure band 5 forth is visible. It may, for example, be a striking red or pink color, so that the color change after attack with a warming agent is readily apparent.
  • thermochromic security feature 10 actually originates from the manufacturer of the security bag or the manufacturer of the security feature 10
  • the reviewer now has to apply a higher temperature in the area 11 of the thermochromic security feature 10, For example, 125 ° and then that the irreversible color change is reversible again and z. B. converted into a transparent color change. As soon as the temperature is removed, the irreversible color change with the striking red or other colored ink sets in again.
  • thermochromic security feature 10 This makes it possible for the first time to control the type and originality of the thermochromic security feature 10.
  • the security feature 10 now turns chemochrom as soon as it comes in contact with the chemical solvent. It suffices here that it is not a liquid contact, but a vaporous influence suffices here for the chemochromic color change.
  • the originality of this chemochromic color change can be checked by the fact that the security feature is likewise adjusted to a temperature of, for example, 10 ° C. B. 125 ° Celsius, whereby the chemochromic color change disappears and this is a feature that it is the manufacturer's intended and intended chemochromic security feature 10.
  • the originality of the chemochromic security feature 10 can be determined.
  • both the security feature 10 reacts chemochromically and thermochromically, whereby the originality can be checked in both cases of action.
