Definitions

  • the invention relates to a device for receiving beverages, such as drinking straw, cup or the like.
  • the invention relates in particular to a color-changeable drinking straw, the surface color of which changes with the falling temperature of the straw when a cold drink is drunk with the drinking straw.
  • the selection of conventional drinking straws ranges from small to large diameter straws depending on the viscosity etc. of the drink.
  • Some of the conventional straws have different patterns on the surface to make them look more beautiful.
  • each straw has a different color or a different pattern, so that everyone in the family can use a different looking straw.
  • the invention has for its object to provide a drinking straw which has a reversible temperature-dependent color-changing active ingredient, by means of which it changes the color when it is used to drink a drink at a temperature other than room temperature, which consequently conveys to the user a drinking pleasure and differs from other straws when drinking a drink.
  • This object is achieved according to the invention by the development of a color-changeable drinking straw, which is characterized in that a mixture of a synthetic resin and a reversibly temperature-dependent active substance is used as the basic body material.
  • a color-changing drinking straw which consists of a base body and a synthetic resin.
