Definitions

  • This invention relates to an environmental and eco-friendly Coaster with an optimized visualization of a print, partly or completely covered by a thermochromic coating, applied on a reusable thermal base with heat absorbing, heat radiating and heat reflexing properties as described in claim number 1.
  • Coasters/Table Mats exist with permanent printed information or images and several of them have special features, for example reflecting surface or special designs. Coasters also exist with heat sensible coatings which almost or completely - depending on the size of the coating - changes optic at different temperatures, eg. when affected by a hot or cold subject.
  • thermochromic coating seeks to solve the disadvantages of printing on stiff materials which are normally used for Coasters - leading to higher printing costs. This disadvantage is solved by printing on materials (mainly film/foils) which are delivered in rolls.
  • the invention according to FR 2908324 does not describe special thermal properties related to the standard thermochromic coating, neither does it describe a specific base with thermal properties for applying a label. So the printed label is per se the Coaster in itself, even if it would have contained materials with special thermal properties.
  • FR 2807324 A3 the Coaster is printed directly on rolls, described as film or foils - meaning flexible materials. In this case, a combination of varying materials with optimized thermal and hence optic properties and the same materials' printing properties would very rarely be flexible and at least not convenient in a normal industrialized graphical production. Furthermore, FR 2807324 A3 describes a variety of the Coaster - illustrated in the applications' fig. 3, where the detachable layers in the Coaster are connected (2-4) with 2 static units (6-7) and where the layers (5) are detachable from the one static unit (7) via a dashed cut (8).
  • the layers in the Coaster are detachable from the static unit (7), but are still unconditionally connected to the other static unit (6).
  • the Coaster does not allow a replacement of parts of the Coaster if for example the images are to be updated.
  • a new campaign with new images would require a completely new Coaster which - if it consisted of materials with special thermal properties - would cause a negative environmental impact.
  • GB 2311371 In GB 2311371 is described a Beer Mat with thermochromic coating printed directly on a suitable material eg. Wood Pulp.
  • a suitable material eg. Wood Pulp.
  • the technique of printing directly on the Beer Mat causes that the Beer Mat must be discarded if a new image is required.
  • the Beer Mat in this case consists of Wood Pulp, the negative environmental impact is low, however, if an optimized optic effect is desired, it requires other materials with special thermal properties, which often are highly environmental and eco- unfriendly.
  • GB 2311371 does not provide any solution to this.
  • the solution to this challenge is described by the present invention of an informative Coaster.
  • a base of any given material with the desired thermal properties is either cut or stamped material by material or in one piece. The thermal base can be placed on stock for later use.
  • the label containing image and information coated with heat sensible ink can be replaced by a new one.
  • the new lablels can then be mass produced from rolls of foil/film and subsequently be applied to the thermal base of the Coaster providing the desired optical effect which is described in the present invention.
  • the present invention describes an improved method to reduce the negative environmental impact of using the Coaster by reusing the base of the Coaster when the image/information on the Coaster needs to be changed.
  • the label on top is applicable to the thermal basis and removable, the label can be changed whenever needed with a new one - eg. for a new campaign.
  • the thermal base and the label can be sold either composite or separately for customer application.
  • the thermal basis is endlessly reusable and does not have a negative environmental impact when changing the image/information of the Coaster.
  • the present invention then obtains the desired optical effect, combustion of the thermal materials is avoided and the effect of this is a reduction of the negative environmental impact when the image/information of the Coaster needs to be changed.
  • the purpose of the invention is to provide a new and environmental friendly Coaster as initially described which by its heat absorbing, heat radiating and heat reflexing properties by thermodynamic imbalance when impacted by an external subject in a simple, practical and environmental and eco- friendly way provides an improved method to regulate the speed of optical change and optimized visual reproduction of the entire display surface of the Coaster even at different sizes.
  • the present invention reduces waste when change of content is needed as the base of the Coaster is reused when the display surface needs to be changed. It is protected by dirt, grime and cleaning by a transparent sealing, preferably containing a heat thermally conductive and/or a non-slip surface.
  • the Coaster according to the invention is peculiar as the said Coaster is based on a material with a low thermal conductivity (Insulating) on which is applied a material with high thermal conductivity and low thermal capacity (heat absorbing and - radiating) and subsequently a self-adhesive label is applied which contains a image and/or information, where the image and/or information is partly or completely covered by a heat sensible, thermochromic coating, changing opacity at a given temperature and subsequently preferably sealed by a protecting laminate - or coating - where the said laminate/coating preferably has a thermal conductive property and a non-slipping surface, avoiding the object placed on it to slip.
  • the thermal base of the Coaster is composite by an adhesive substance.
  • the label with print, thermal coating and laminate are permanently applied to each other.
  • the thermal base and the label are detachable from each other.
  • the Coaster according to the invention is mainly used to protect a table from a subject in thermodynamic unbalance with the Coaster and has a heat sensitive coating changing opacity at temperature is higher than normal room temperature when it is used to protect against hot subjects, while the heat sensitive coating changes opacity at lower temperature when protecting against colder subjects.

  • thermochromics print is applied to change optic from respectively visible to transparent or reverse when being affected by an external object which is in thermodynamical unbalance with the Coaster.
