  • An apparatus for packaging a product in sachets or the like, in particular in the form of packs of the type with sealed edges, the sachet comprising a first and a second flap, positioned opposite one another, forming an internal space for holding a product; the apparatus comprising: means for preparing a web with a first and a second flap which are paired up; means for forming longitudinal portions of the two-layered web, forming a sachet having an internal space between the flaps for holding the product; means for inserting the product in the internal space corresponding to the internal space of the portions forming the sachet, comprising product dispensing means; characterised in that the means for dispensing the product in the internal space corresponding to the internal space of the portions forming a sachet operate during the step of preparing the longitudinal portions forming sachets in the web.
  • the product can be inserted in the sachet in the time usually taken to perform another packaging operation.
  • the numeral 10 denotes as a whole a first preferred embodiment of a schematically illustrated apparatus for the production of sealed pouches or sachets containing a product.
  • the sachet is of the type with sealed edges and, in the customary way for the sector, comprises a first and a second flap which are positioned opposite one another, forming an internal space for holding a product and an external zone for adhesion between the first and the second flaps, so as to seal the internal space holding the product.
  • the first preferred embodiment of the apparatus 10 for packaging a product in sachets or pouches and similar packs comprises means 12 for preparing a web 14 which is closed at the bottom 15, having a first flap and a second flap 16, 18 which are paired up and substantially fit together; the top of the two-layered web 14 having an opening 20.
  • the first preferred embodiment of the apparatus 10 also comprises means designed to form longitudinal portions 13 of the two-layered web, forming a sachet with an opening 20 at the top for filling and an internal space 22 for holding the product between the flaps 16, 18.
  • the means for preparing the longitudinal portions 13 from the two-layered web 14 to form a sachet comprise means 24 acting in longitudinally distanced zones of the two-layered web 14, designed to join two opposite transversal and vertical strips 13a, 13b of the web flaps 16, 18.
  • the means 24 for joining two opposite strips of the opposite flaps 16, 18 of the two-layered web 14 tightly clamp said vertical strips of the opposite flaps 16, 18 together using opposite transversal elements or plates 24a, 24b.
  • said means 24 for joining two opposite zones of the opposite flaps of the two-layered web form means for sealing the opposite flaps 16, 18 of the two-layered web, sealing together the strips or parts of the web that they clamp against one another.
  • the present apparatus also comprises means for inserting the product in the internal space 22 of the portions forming the sachet, the insertion means comprising product dispensing means 26.
  • these dispensing means are in the form of a hopper or nozzle designed to dispense a predetermined amount of liquid.
  • the dispensing means 26 in particular the hopper type, have side or longitudinal walls 26a, 26b which converge towards the product dispensing end 26c, and transversal front and rear walls 26d, 26e.
  • the first preferred embodiment of the apparatus 10 also comprises means for closing the longitudinal portions forming the sachet, with the product held in its internal space.
  • these closing means are not illustrated in detail in the accompanying drawings.
  • the means 26 for dispensing the product in the portion 13 forming the sachet operate during the step in which the longitudinal portions 13 which will form the corresponding sachets are being prepared in the two-layered web 14. In this way, this operating step, that is to say, preparation of the portions to be filled, can be performed simultaneously with filling of the same portions.
  • the means 26 for dispensing the product in the portion 13 forming the sachet operate, as illustrated, during the step of preparing transversal joins in the web 14, forming the longitudinal portions 13 of the web which form the corresponding sachets.
  • the apparatus also comprises means for cutting and separating the full sachet portions, which substantially cut the middle of the joins 13a, 13b between the web flaps which delimit the portions forming respective sachets, in order to obtain sachets which are completely separate from one another and contain a respective product.
  • the cutting and separating means operate after the upper closing means for the portions forming the sachets.
  • these cutting and upper closing means are not illustrated in detail in the accompanying drawings.
  • the product is inserted in the internal space 22 of the respective sachet portion 13 by the product dispensing means 26 in the inserted condition with their side faces in contact with the internal surfaces of the flaps 16, 18 of the corresponding sachet portion 13 that are fitted together. This limits the distance over which the product must fall, containing the risk of part of the product coming out of the pack being produced.
  • the product dispensing means 26 are inserted in the portion 13 forming the sachet to supply the product to it.
  • the product dispensing means 26 are inserted between the flaps 16, 18 of the two-layered web 14 before the step of joining the transversal strips of the web, which form the rear join or the join upstream of the portion to be filled 13.
  • the product dispensing means 26 operate on the sachet portion as the portion forming the sachet is fed forward. That is to say, the product dispensing means 26 insert the product in the sachet portion while the two-layered web is fed forward.
  • the means for joining suitable longitudinally equidistant zones of the opposite flaps of the web to form the sachet portions 13 operate with the two-layered web 14 as it is fed forward.
  • said apparatus comprises a plurality of dispensing elements 26 which are aligned in the direction of feed.
  • the product dispensing means 26 are inserted between the opposite flaps of the two-layered web 14 before rear or upstream clamping of the web zone 15b which forms the sachet portion 13 filled using the dispensing means 16.
