Definitions

  • the present invention relates to a device for connecting a thread-like element to a paper body.
  • the device is particularly but not exclusively used to connect a bag for infusions such as tea, camomile, etc. (i.e. a bag to be immersed in a liquid) to the cotton thread used to handle it.
  • a bag for infusions such as tea, camomile, etc.
  • the device is used in the same manner to connect the other end of the thread to the tag which identifies the product contained in the bag.
  • the tag which identifies the product contained in the bag which as is known is constituted by a small pouch made of porous paper, is associated with the other end of the thread in the same manner, by means of metal staples.
  • metal staples when immersed in the hot water used for the infusion, are subject to oxidation, in particular if the material which constitutes them is aluminum, and the oxide thus formed, which is toxic and thus harmful to the health, dissolves and is consequently ingested by the user.
  • the aim of the present invention is to provide a device which replaces metal staples for the association of the cotton thread with an infusion bag and with its corresponding identification tag.
  • a consequent primary object is to provide a device which is non-toxic and thus not harmful to the health.
  • Another important object is to provide a device by means of which the association between the thread and the bag is particularly stable, so that the rules of hygiene which justify the presence of the cotton thread are preserved.
  • Not least object is to provide a device which does not compromise the aesthetics of the flaps on which the ends of the thread are fixed.
  • a device for connecting a thread-like element to a paper body, particularly a paper body to be immersed in a liquid characterized in that it comprises a sheet element which is fixed by hot-pressing onto said paper body, thereby enclosing an end of said thread-like element, said sheet element being composed of layers of supporting material and of external covering material alternated with layers of heat-welding material.
  • an infusion bag is indicated by the reference numeral 1, and the end 3 of a cotton thread 4 for handling said bag is fixed adjacent to the upper flap 2 of said bag.
  • Fixing occurs by means of the heat-welding of a sheet element constituted by a multilayer strip 5 which is hot-pressed onto the flap 2, enclosing said end 3.
  • Said strip 5 has various alternated layers of material; a first one 6 is constituted by extruded polythene which, when heated, adheres to the flap 2 of the bag 1, and a second layer 7 is constituted by polyester which constitutes the supporting element for the other layers.
  • a third extruded polythene layer 8 is used to connect a fourth covering layer 9 made of paper to the third layer 8.
  • the second polyester layer 7 is provided to give strength to the strip, whereas the presence of the third extruded polythene layer 8 is necessary for the gluing of the fourth covering layer 9 onto the polyester, which is otherwise troublesome.
  • the fixing of the end 3 of the cotton thread 4 occurs by arranging said thread downward so as to ultimately improve traction strength.
  • connection between the thread 4 and the bag 1 is considerably strong.
  • a strip 12, identical to said strip 5, is used to fix the other end 10 of the cotton thread 4 to the identification tag 11 of the product contained in the bag 1, with the same welding operations.
  • the tag 11 which as mentioned above bears the printed indication of the product and of the maker, can be connected to the thread 4 in two different manners.
  • connection device according to the invention has achieved the intended aim and objects, since it is capable of excellently replacing the metallic staples currently used without having the disadvantages and the problems which characterize said staples.
  • the materials employed may be any according to the requirements.
