Definitions

  • the present invention relates to a bundle of detachable sheets which can be used for packaging foodstuffs or other products.
  • Document FR-A-2 247 071 describes a bundle of packaging sheets in which the different sheets, previously cut to the desired format, are joined together by gluing, stapling, or riveting, and include a separation or perforation line allowing the detachment of the sheets by simple manual traction on a gripping means.
  • Gripping means envisaged in this French patent consist either of a fold made in one of the lower corners of the sheets or a fold made along the lower edge of the sheets.
  • Document FR-A-2 269 425 which is an addition to FR-A-2 247 071 also describes a bundle of packaging sheets similar to that of the main patent, the sheets of which may include, as gripping means, holes provided in each of the sheets to allow the insertion of a finger of the user and thus facilitate the grasping of the sheet, ie an embossing along the lower edge of the sheets.
  • the presence of a fold at the bottom of each of the sheets of the bundle has the disadvantage of doubling the thickness of the bottom of the bundle at the folds, because each fold consists of a double thickness of leaf.
  • the presence of these folds and this difference in thickness of the bundle makes it difficult to receive the sheets at the end of the machine which performs the folds because it is not possible to automatically store the leaves which, due to the presence of double thickness at one end, do not form a regular parallelepiped.
  • the presence of this extra thickness at one end of the sheets and of the bundle does not allow automatic counting, with separation of packets from a given number of sheets in order to individualize identical bundles. For this reason, the bundles were until now sold by weight, from an approximate thickness, which prohibited the marketing of a perfectly standardized product.
  • the object of the present invention is therefore to provide a bundle of sheets overcoming the above drawbacks.
  • the object of the invention is to provide a bundle of sheets, the sheets of which can be easily grasped and detached by a user, one by one, without contact with the other sheets of the bundle, which guarantees good hygiene.
  • Another object of the invention is to provide a bundle of sheets which does not have any extra thickness, resulting in a gradual winding of the sheets.
  • Another object of the invention is to provide a bundle of sheets having a determined number of sheets, this number being determined by automatic counting of each of the sheets during the manufacture of the bundle.
  • the present invention aims to provide bundles of sheets having a practically constant thickness maintained over the entire length of the bundle, thus allowing more regular packaging of the bundles during their packaging for dispatch.
  • a bundle of sheets is produced in which the different sheets, previously cut to the desired format, are joined together along a first transverse edge and are each provided, in a second transverse edge opposite the first transverse edge, gripping means consisting of a fold characterized in that the thickness of each sheet is reduced, in an area adjacent to the second transverse edge of width at least equal to the width of the fold, by a value between 20 and 40% compared to the initial thickness of the sheet.
  • the zone of reduced thickness has a width equal to that of the fold.
  • the zone of reduced thickness has a width twice that of the fold.
  • each sheet of the bundle may also include an embossing formed along the first transverse edge, this embossing preferably being such that the thickness of each sheet at the level of the embossing is approximately equal to the total thickness of each sheet at the fold area formed along the second transverse edge.
  • the sheets which can be used in the bundles of the present invention are all sheets such as sheets of paper, translucent or opaque, and in particular sheets of paper intended for packaging, for example of food products.
  • the sheets can also be coated on one side, for example with products suitable for contact with food products, such as only paraffin.
  • the sheets used for the bundles of the present invention have a grammage between 20 and 50 g / m 2 , and the grammage chosen being a function of the intended use.
  • the sheets of the bundles of the present invention are joined together along the first transverse edge by gluing, stapling or riveting, and preferably comprise near this first transverse edge and parallel to this a line of separation or perforation allowing easy detachment of the sheets by simple manual pulling on the gripping means.
  • the bundle may also include, in the vicinity of the first transverse edge, one or more openings such as holes, allowing its adaptation to a hook, peg or suction cup, for attachment to a wall close to the user.
  • each sheet of the bundle of sheets according to the invention comprises a gripping means constituted by a fold formed along the second transverse edge of the sheet, opposite to the first transverse edge.
  • this fold extends over the entire length of the second transverse edge parallel to this edge, but could also consist of a fold formed in one of the corners of the second transverse edge.
  • the fold has a sufficient width to allow easy gripping of the sheets and which avoids excessive consumption of paper.
  • the fold will have a width of between 15 and 30 mm, a width of 25 mm being recommended.
  • the thickness of each of the sheets of the bundle is reduced, in an area adjacent to the second transverse edge of width at least equal to the width of the fold, by a value of between 20 and 40% relative to the initial thickness of the sheet, preferably 30%.
  • the width of the reduced thickness zone is as indicated at least equal to the intended width of the fold, that is to say the width of the part of the sheet intended to be folded up to form the fold or flap.
  • the initial thickness of the sheet is that of the sheet before any reduction in thickness.
  • the width of the zone of reduced thickness is twice that of the fold or flap, in other words the zone of reduced thickness comprises the fold or flap and the surface of the sheet immediately below this fold or flap.
  • a reduction of more than 40% in the thickness of the sheet would be difficult to achieve and would risk weakening the fold to such an extent that the sheet would tear at this fold during use. Reducing the thickness of the sheet by less than 20% does not reliably provide the advantages of the present invention.
  • the zone of reduced thickness of the sheets can be produced by laminating, between two knurls, a continuous strip of paper in a zone adjacent to a transverse edge of the strip.
  • the knobs can be heated to increase the calendering and therefore reduce the thickness of the paper at the fold.
  • the thickness reduction can be adjusted.
  • the fold is then formed in a conventional manner and the strip is cut into sheets which are received, at the end of the machine, under form of regular parallelepiped bundles.
  • an embossing having a width of between 1 and 5 cm and preferably 2 and 3 cm.
  • the embossing is such that the thickness of the sheet, at the level of this embossing, is equal to the thickness, approximately, at the level of the fold formed in the second transverse edge of the sheet.
  • a bundle of sheets 1 according to the present invention.
  • the bundle of sheets is held in a rigid support 7, for example of cardboard, for the transport or the distribution of the sheets of the bundle.
  • the support comprises a rigid bottom element of dimension greater than the sheets, a portion of which, projecting beyond a first transverse edge 3 of the sheets, is provided with openings 9, for example holes to allow attachment to a wall.
  • the support further comprises a flap which encloses the bundle of sheets over it and which is fixed so as to hold all of the sheets along the first transverse edge by means, for example, of staples 8.
  • Each of the sheets of the bundle comprises parallel to the first transverse edge and slightly below the staples 8 a transverse line of perforation allowing easy separation of the sheets.
  • a fold or flap 5a is formed, along a fold line 4a, along each of the second transverse edges 4 of the sheets 2, opposite the first transverse edge 3 of the sheets.
  • the thickness of each sheet has been reduced in an area 5 adjacent to the second transverse edge of the sheet by a value of 30% relative to the initial thickness of the sheet. As shown in FIG. 2, this zone of reduced thickness 5a in the embodiment shown has a width equal to the width of the fold or flap 5a.
  • FIG. 4 shows another recommended embodiment of a bundle of sheets according to the invention.
  • This bundle is generally similar to the bundle shown in Figures 1 to 3 but further comprises an embossing produced in the upper part of each of the sheets 2 of the bundle parallel to the first transverse edge 3 of each of the sheets, near the latter, and preferably slightly below the perforation line 6.
  • the embossing of each sheet 2 is such that the thickness of each sheet, at the level of the embossing 10, is equal to approximately the total thickness of each sheet at the level of the fold 5a, that is to say the sum of the thicknesses of fold 5a and of the surface of the sheet directly below this fold.
  • the embossing 10 will therefore preferably result in an increased thickness of the sheet in the embossing area. about 70% compared to the initial thickness of the sheet.
  • the bundle of sheets has practically equal thicknesses at its two opposite transverse ends leading to bundles of more regular parallelepipedic sheets, the number of sheets of which can be predetermined.
  • this embossing has a width of between 2 and 3 cm.
  • a bundle of sheets is thus obtained which has a practically regular thickness and comprising a predetermined number of sheets.
