Definitions

  • the invention relates to a method for scenting packaging material by directly applying fragrances to this material (EP-A-4463). It also relates to an agent for scenting packaging material and the use of a fragrance paste according to the aforementioned method.
  • fragrances are usually contained directly in the product, so that the consumer has the fragrance experience both when opening the packaging and when using the products.
  • fragrances are unstable to a large number of ingredients in washing and cleaning agents. This applies, for example, to chlorine as hypochlorite or bound to organic chlorine carriers such as sodium dichloroisocyanurate and trichloroisocyanuric acid.
  • Perborate in combination with bleach activators can also negatively affect the stability of fragrances.
  • these disadvantages can be avoided by scenting the packaging material, in particular the carton used as packaging. A direct contact of the fragrances with the disruptive ingredients then practically does not take place.
  • the fragrances are preferably applied in the inner upper part of the packaging with the aim of being absorbed in the cardboard material.
  • a method for impregnating cardboard with liquid fragrances is known from EP-A-4463.
  • fragrances are therefore “nose-shaped” and there are visible spots. Furthermore, when the fragrances are sprayed and the associated fragrance nebulization occurs, considerable losses of fragrance occur, which not only reduces the economics of the process but also causes a strong, unacceptable odor nuisance to the environment of the fragrance systems for the operating personnel. Finally, the fragrances cannot be distributed according to the previous method in a precisely placed manner that is desired for optical reasons.
  • the object of the invention is to provide a method for scenting packaging materials which ensures exact placement of the fragrance without the risk of undesirable staining and without significant loss of fragrance.
  • the solution according to the invention consists in the method measures according to the claims.
  • the pure liquid, low-viscosity fragrance is not applied to the packaging material, but rather higher-viscosity fragrance pastes with preferably thixotropic properties are used, which enables the packaging material to be smell-free and practically loss-free with precisely placed fragrance application.
  • Silicic acids or organically modified layered silicates are preferably used as additives or gelling agents. These substances, which are already known in the other context for solidifying or thickening liquid or soft substances - also in DE-PS 819 846 and 870 242 - as agents for producing pastes with thixotropic properties are preferably used in amounts of 1 to 20%, in particular 2.5 to 15%, incorporated into the fragrances.
  • fragrances are advantageously carried out with the aid of stirrers which exert high shear forces.
  • the final viscosity of the resulting fragrance pastes depends on the ratio of the amount of fragrance to the amount added.
  • solvents with different polarities can be added to the fragrances.
  • fragment encompasses individual fragrances as well as combinations of fragrances. The same applies to the terms “silica” and “layered silicate”.
  • the invention also provides a means - in other words a fragrance paste - for scenting packaging material in accordance with the method according to the invention.
  • This agent is characterized by the composition of a fragrance and an organic, modified layered silicate incorporated therein, which promotes paste formation and increases the viscosity of the fragrance, as a gelling agent in the form of a fragrance paste.
  • the fragrance paste according to the invention should preferably have thixotropic properties and contain silica or organically modified layered silicate in the proportions given above as the gelling agent.
  • the solution according to the invention is characterized by the use of a fragrance paste produced by incorporating a fragrance into a gelling agent which promotes paste formation and increases viscosity, in particular with thixotropic properties, for fragrancing packaging material by applying to this material in accordance with the method according to the invention.
  • the gelling agents in particular the layered silicates, absorb fragrances and thus, with an associated interaction of fragrance on the one hand and gelling agent or additive on the other hand, lead to a delayed release of fragrance. This results - especially when layered silicate is used as an additive - in extended times of fragrance perception on the packaging materials coated with the fragrance paste.
  • Pyrogenic silicas ie those produced by flame hydrolysis of silicon tetrachloride in the oxyhydrogen flame, are preferably used as gelling agents.
  • Such a very pure, highly disperse silica of defined particle size and chemical composition is sold by Degussa under the name "Aerosil 200".
  • This material specially developed for thixotroping, thickening or reinforcement, has a BET surface area of approximately 200 m 2 / g.
  • the fragrance pastes are applied to the respective packaging material, for example by spraying, knife coating or brushing.
  • scented paste can be applied to the scent of cardboard containers preferably by feeding the respective container 1 with the open side upwards in a transport direction 2 to a machine 3 and continuously introducing it into a circular path 4.
  • a scenting device 5 can then expediently be immersed in the container 1 in such a way that an application of fragrance paste can be carried out with the aid of an application device 6 which has two nozzles 7, each offset by 180 ° C.
  • the fragrance paste can be applied at a pressure of 1 to 3 bar with a circular movement of 180 ° on the wall of the container in such a way that a narrowly defined strip of fragrance paste is formed on the entire inner circumference of the container.
  • the application device 6 can be moved out of the container 1 again and transported further and delivered to a conveyor belt 8.
  • the rotary movement can also be effected by rotating the container when the nozzle is at a standstill.
  • the scenting of packages in particular rectangular boxes, can be carried out.
  • the packages 10 are opened with an opened closure flap 11 on a continuous or clocked transport device belonging to a filling system 12 with a floor guide 13 and cup chain 14 to an application device 15.
  • the closing flap which is at the rear in the direction of travel 16, is touched and moved away by an application roller 17 loaded with the fragrance paste.
  • the application roller 17 describes a curve 18 in such a way that it first dips into the package 10, runs out of the package 10 along the rear closure flap 11, and then runs along a container 19 filled with fragrance paste, from the latter is again supplied with paste and then immersed again in the package.
  • This processing can be carried out with high performance, especially when connected to the main drive shaft of the packaging machine.
  • a container made of more or less absorbent materials (e.g. cardboard) is treated as in Example 11 when using 0.5 grams of fragrance pastes from Table 8 above with a spray pressure of 1.0 bar. The order is again flawless; the environment is not unduly burdened either.
