Definitions

  • the filter if abandoned in the sea, breaks up into microplastics that become part of the marine food chains.
  • a study by the Federico II University of Naples is examining the degradation time of butts and the results of the first two years of research are not at all comforting: the degradation of cigarette butts is, in fact, rapid in the first months, when they degrade the external component, paper. Later, however, it almost stops completely, because the microorganisms responsible for the decomposition are unable to attack the substances that make up the butt. Therefore, it remains in the environment, giving rise to plastic fragments and toxic substances.
  • a study by San Diego State University has shown, through laboratory experiments, that a single cigarette butt in a liter of water is enough to kill much of the marine and freshwater fauna.
  • biodegradable filters made, for example, of natural materials such as cotton, hemp and linen.
  • biodegradable filters made of cellulose on the market but this entails, however, damage to the environment as the filters thus made determine the felling of trees in addition to the damage that occurs in their production.
  • the purpose of this invention is to create a filter for cigarettes made of biological material.
  • Figures la, lb, lc and Id illustrate the preparation steps of a first embodiment of the filter according to the present invention
  • Figure 2 illustrates an axonometric view of the closed filter made according to the steps shown in Figures la- Id;
  • Figure 3 illustrates a front view of the filter according to a second embodiment of the present invention
  • Figure 5 illustrates a longitudinal section of the filter according to a fourth embodiment of the present invention.
  • the filter comprises a through separation structure 2 which determines the formation of compartments 3 suitable for the passage and filtration of smoke.
  • the structure 2 and the tubular element 4 are of adequate dimensions to be coupled with a common paper for making cigarettes.
  • the filter is made starting from a single sheet of paste 1 by rolling it on itself, as illustrated in Figures la- Id. In particular, it is sufficient to make a three-quarter fold of the sheet 1 and then roll the strip to form a tubular element.
  • a separation structure 2 is formed, substantially S-shaped and arranged in a central position with respect to the circumference of said sheet 1. This S shape preferably extends along the entire length of the filter.
  • the same shape can, however, be made by means of a mold.
  • the separation structure 2 seen in cross section, is substantially M-shaped and is inserted inside the tubular element 4. This M shape extends preferably along the entire length of the filter.
  • the separation structure 2 seen in longitudinal section, has a wavy conformation preferably for the entire length of the filter and is suitably provided with holes capable of allowing the passage of smoke.
  • Said structure 2 with corrugated conformation is inserted inside the tubular element 4.
