Definitions

  • the present invention regards a hygienic product and the apparatus for its manufacture.
  • the invention regards a hygienic product admixed with at least one substance which is activated in direct contact with water or moist surfaces, and the apparatus specifically designed for the industrial manufacturing thereof
  • wet wipes i.e. sheets of paper or fabric soaked with water and/or detergents, disinfectants or other similar products, used for hygienic purposes for cleaning parts of the body, or even for cleaning surfaces or objects.
  • wet wipes are packaged in packs or bags that are rather complex and heavy, normally comprising an opening which must allow the simple and quick extraction of the wipes themselves, one at a time, and which must be effectively reclosed in order to prevent the liquid with which the wipes are soaked from quickly evaporating away, this compromising the effectiveness of the use of the product.
  • the liquid with which the wipes are soaked frequently contains considerable amounts of preservative substances, perfumes or deodorants or other additives.
  • such liquid essentially comprises a component which acts as a carrier for active principles, e.g. detergents or disinfectants; most of the weight of the product, therefore, is conferred by only the carrier component.
  • active principles e.g. detergents or disinfectants
  • the wet wipe after its use, is normally not recyclable, and hence it constitutes unsorted waste that must of course be adequately disposed of (unless it is not released into the environment by fearful users).
  • the used wipe constitutes a waste product that comprises not only paper or fabric, but also the aforesaid additive substances that can often be harmful for the environment.
  • the object of the present invention is to improve the background art.
  • an aim of the present invention is to implement a hygienic product that allows obtaining an effective cleansing action on body parts, surfaces, or other, but with limited weight with respect to analogous products present on the market.
  • Still another aim of the present invention is to provide a hygienic product with cleansing/disinfectant function that allows obtaining a considerable savings in terms of chemical substances used.
  • a further aim of the present invention is to achieve a hygienic product with cleansing/disinfecting function that is cheaper than analogous products present on the market.

  • the apparatus for manufacturing the aforesaid hygienic product comprises at least one station for applying the layer of cleansing/disinfecting product on the surface of the yielding laminar support, and means for advancing the yielding laminar support in the form of a continuous strip that crosses the application station.
  • the application station comprises at least one airtight distribution chamber for the cleansing/disinfecting product, means for feeding the product towards the distribution chamber, and means for drawing the product from the distribution chamber and applying it on aforesaid surface of the continuous strip.
  • reference number 1 overall indicates, only as a non-limiting example, a hygienic product according to the invention.
  • the hygienic product 1 comprises at least one yielding laminar support 2.
  • the yielding laminar support 2 is provided in roll form 3.
  • the yielding laminar support 2 can comprise a plurality of pre-cuts 4, equidistant from each other, adapted to separate sheets 5 that can be separately used.
  • yielding laminar support 2 can be provided in any one other form of practical use for the user.
  • the yielding laminar support 2 is provided in tissue form 6, wipe form or the like.

  • the yielding laminar support 2 comprises a first surface 2a and a second surface 2b, opposite each other.
  • At least one of the surfaces 2a,2b can be intended for contact with surfaces to clean and/or hygienize; in some applications, both surfaces 2a,2b can be indiscriminately intended for such contact, i.e. the product 1 can be indiscriminately used on one side or on the other side.
  • first surface 2a and second surface 2b of the yielding laminar support 2 are entirely conventional, only for the purpose of an improved comprehension of the features of the invention, as will be clearer hereinbelow.

  • the behavior of the various embodiments of the hygienic product 1 illustrated, when placed in contact with water or moist surfaces, can be mutable in relation to the final structure of the product 1 itself: for example, in the case of the embodiments of figures 3,4 , the activation of the product that constitutes the layer 7 - and hence its entrance into the aqueous solution which will carry it - will be immediate, while in the case of the embodiments of figures 5,6 the activation of its product that constitutes the layer 7,7a, and hence its release into the aqueous solution, will be more gradual.

  • the product 1 could also be rinsed after the first use, in which the cleansing/disinfecting product had been activated.
  • the rinsing carried out after the first use allows cleaning the surfaces 2a,2b of the laminar support 2 of the product 1, and if desired possible residues of cleansing/disinfecting product can also be eliminated in order to be able to clean consequently again the surface to be treated simply with water.
  • a yielding laminar support 2 made of a material that allows receiving/absorbing a greater amount of cleansing/disinfecting product, for example in order to achieve product structures like those according to the embodiments of figures 5 and 6 .
