Definitions

  • the present invention relates to the field of packaging bags.
  • the present invention relates to the field of packaging bags comprising opening / closing means capable of multiple successive openings and closings, for example and not limited to in the form of complementary profiles.
  • the object of the present invention is to improve the known sachets.
  • a packaging method which comprises the steps consisting in:. provide a bag comprising at its mouth, on the one hand opening / closing means capable of multiple successive openings and closings and on the other hand, at a distance from these, on the inside of the bag by relative to said opening / closing means, a breakable connecting veil,. introduce contents to be packaged in the sachet and. tightly close this sachet in tension on said content, said veil in contact with the content avoiding the application of constraints on the opening / closing means, but allowing, after rupture, free access to the content by means of said means opening / closing and then allowing the bag to be released in the closed state thanks to the distance separating the veil and the opening / closing means.
  • the present invention also relates to a packaging device comprising:
  • means for supplying a sachet comprising at its mouth, on the one hand opening / closing means capable of multiple successive openings and closings and on the other hand, at a distance from these, on the side of the inside the bag with respect to said opening / closing means, a breakable connecting veil,
  • the present invention finally relates to sachets comprising at their mouth, on the one hand opening / closing means capable of multiple successive openings and closings and on the other hand, at a distance from these, on the side of the inside the sachet relative to said opening / closing means, a breakable connecting veil, such that when the sachet is tightly closed in tension on a content, said veil in contact with the content avoids the application of stresses on the means opening / closing, but authorizes, after rupture, free access to the content via said opening / closing means and then allows the bag to be released in the closed state thanks to the distance separating the veil and the means d 'open close.
  • FIG. 1 schematically represents the basic principle of a sachet in accordance with the present invention tightened in the storage position on its contents
  • FIG. 2 schematically represents the same bag after a first opening
  • FIG. 3 represents a sectional view of the mouth of a bag according to a first embodiment of the present invention
  • FIG. 4 represents a sectional view of the mouth of a sachet, in accordance with a second embodiment of the present invention
  • FIG. 5 represents a sectional view of the mouth of a bag according to a third embodiment of the present invention
  • FIG. 6 schematically represents an example of application of the present invention.
  • FIG. 1 and 2 There is schematically shown in Figures 1 and 2 attached a bag according to the present invention, respectively in the tight storage position on its contents, and after a first opening.
  • the bag according to the present invention essentially comprises two main walls 10, 20, an opening / closing means 30 and a web 40 which connects the walls 10, 20 to each other on the inside of the opening / closing means 30 and at a distance therefrom.
  • the walls 10, 20 can be the subject of numerous embodiments. They are preferably walls made of thermoplastic material. These walls 10, 20 can be mono or multilayer (s) and mono or multi-material (x). If necessary, it may be a paper support coated with a layer of thermoplastic material, or else a layer of metallized thermoplastic material.
  • the opening / closing means 30 and the veil 40 extend parallel to each other across the mouth of the bag.
  • the methods of connecting the walls 10, 20 can be the subject of numerous variants.
  • the walls 10, 20 can be connected together, for example by welding or gluing, on their two sides perpendicular to the mouth and by means 30 and web 40, the ends of the walls 10, 20 opposite the mouth being initially separated but close together, superimposed and interconnected by any suitable means, for example by welding or gluing, once the content has been placed in the sachet.
  • the opening / closing means 30 can also be the subject of numerous embodiments.
  • They can be formed of complementary male 33 and female 34 profiles respectively arranged on the walls 10, 20 or on respective support webs 31, 32 linked to these. It may be additional means in the form of hooks. It may also be opening / closing means of the velvet / crochet type. All of these means are well known to those skilled in the art. They will therefore not be described in detail later.
  • these opening / closing means 30 can be controlled by a cursor 50.
  • FIG. 1 Such a cursor has been shown diagrammatically in FIG. 1 attached. Again it can be the subject of numerous embodiments.
  • Such a slider 50 preferably comprises a sole 52 which carries two side fabrics 54, 55 and a central wall 56 defining between them two non-parallel channels 57, 58 respectively receiving at least the top of one of the two support webs 31, 32 of the opening / closing means 30, so that, according to the direction of movement of the cursor 50, the latter urges the means 30 respectively upon opening and closing. If necessary, but this arrangement is not imperative, the central wall 56 can penetrate between the complementary profiles.
  • the present invention makes it possible to avoid any untimely and unintentional opening of the sachet, in particular during handling before use.
  • the internal section of the bag is increased by twice the value of the distance D separating the opening / closing means 30 and the veil 40.
  • the bag is thus released and the user can easily access the content 100 despite the initial state of compression thereof.
  • the distance D separating the opening / closing means 30 and the web 40 is typically of the order of 2 to 5 cm.
  • the configuration of the mouth of the bag comprises at least one welding step.
  • a closure assembly 300 formed of a sheet 302 folded in a U shape on itself and comprising the opening / closing means 30 at its opening contour, is welded outwardly concavity on the mouth of the bag between the walls 10 and 20.
  • the middle part of the sheet 302, that is to say the fold thereof plays the role of the veil 40.
  • the sheet 302 can be fixed, for example by bonding or welding, on the walls 10 and 20 over the entire height of its surface in contact with them.
  • the sheet 302 can be fixed to the walls 10 and 20 only near its central zone, at the level of the zones referenced 303 and 304 in FIG. 3.
  • the sheet 302 is also fixed to the walls 10 and 20 near its free edges, at the areas referenced 305 and 306 in FIG. 3.
  • FIG. 4 shows a second embodiment in accordance with the present invention of the mouth of a sachet which consists in folding over itself in W a sheet 312, in the form of a central fold 318 and two lateral folds 317 and 319, and to weld at 313 and 314 the top of the central fold 318 thus formed on the adjacent surfaces of the lateral elements of the sheet.
  • the lateral folds 317 and 319 can also be welded at 315 and 316 near the top of the mouth.
  • the opening / closing means 30 are provided inside the central fold 318, between the two lateral folds 317 and 319.
  • the means 30 may have come from material, in particular from extrusion, on the sheet 312, or reported and fixed by any appropriate means, in particular by welding or bonding thereto.
  • FIG. 5 shows a third embodiment of the mouth of a sachet in accordance with the present invention which consists in folding in a U on itself a sheet 320 forming the main walls 10 and 20 of the sachet, then at fix on the outside of this fold, a closure assembly comprising two support webs 31, 32 which carry respective means 33, 34.
  • the support webs 31, 32 can be fixed on the sheet 320 by any suitable means for example by welding or gluing.
  • the present invention is not limited to the particular embodiments which have just been described, but extends to all variants in accordance with its spirit.
  • the mouth comprising the means 30 and the veil 40 can be integrated for example in the fold of a bellows of a packaging bag.
  • the present invention may find particular application in the production of sachets for packaging diapers for babies or any equivalent means of protection.
