Definitions

  • the present invention relates to a device constituting packaging for doses of pasty material, as well as the method of manufacturing this device.
  • This prior document discloses a device for storing and distributing doses of pasty material, which comprises a volume for receiving the dose of pasty material and a means for closing this volume, which can be opened for dispensing the dose of pasty material.
  • this device consisting of two superimposed sheets, firmly welded to each other, the first formable sheet of which, for each dose, has a deformation directed away from the junction surface of the two sheets, under shape of a cell constituting volume for receiving the dose of pasty material
  • the device also comprising a conduit for discharging the dose of pasty material constituting an unwelded zone in the form of a corridor, formed between the first sheet which comprises the cell and the second sheet, duct open at one of its ends and opening through its other end into the cell, as well as a flexible membrane, constituted nt closure means, which achieves a separation between the cell and the conduit, and which, in the zone of the conduit, is assembled to said first sheet in which the cell is formed to constitute at this location an easily tear-off closure, or fragile
  • the second sheet has, prior to the welding of said second sheet to the first sheet, a second deformation, in the form of a channel constituting an evacuation duct, also directed away from the surface. of junction of the two sheets.
  • this second deformation constituting the channel directed away from the alveolus receiving the dose of pasty material allows the use of a flat membrane, arranged along the junction plane of the first and second sheets and realizing the separation between the cell and the channel arranged on either side of this junction plane.
  • This protruding channel on the face of the packaging opposite the cell receiving the dose of pasty material on the one hand complicates the production of the device, and on the other hand increases the size of the packaging.
  • the object of the invention is therefore to remedy these drawbacks by producing a packaging of the aforementioned type, in which, at the location of the evacuation duct, that is to say none of the first and second sheets are deformed, the evacuation duct resulting then exclusively from the existence of the non-welded zone, that is to say the first sheet, the flexible membrane following in the latter case the deformation of the first sheet in the zone where it is assembled to it, the second sheet then being a flat sheet of rigidity greater than that of the first sheet.
  • the easily tearable or fragile closure formed, in the evacuation duct, by the membrane assembled to said first sheet in which the cell is formed is produced by a fragile connection of the membrane to this so-called first leaf.
  • the fragile closure formed, in the evacuation duct, by the membrane assembled to said first sheet in which the cell is formed is produced by a pre-notched weakening zone formed in the membrane.
  • the invention also relates to the method for producing such a device.
  • channels are formed in the said second sheet and the first and the second sheet are juxtaposed by their face away from the deformations.
  • the second sheet brought to the welding step is a flat sheet, and in the first sheet, no deformation constituting a channel for the evacuation duct is carried out before the welding.
  • the flexible membrane is placed on the sheet in which the cells are formed, so as to extend beyond them on all sides, a weld is produced between the deformable membrane and the sheet in which the cells are produced, over the entire periphery of each cell, the second sheet, of rigidity greater than that of the first sheet in which the cells are formed, is placed on the assembly thus formed, the second sheet is firmly welded hot to the assembly consisting of the first sheet and the flexible membrane, over their entire junction surface, excluding the areas occupied by the cells and the corridor each time joining a cell at the edge of the device and constituting conduit evacuation, the heat of the weld ensuring a lasting bond between the first sheet, the membrane and the second sheet over the entire welded area and producing, in the non-welded corridor, a channel-shaped deformation of the first sheet secured to the deformable membrane.
  • the weld produced between said membrane and this sheet is a weak, fragile weld.
  • the flexible membrane prior to the step of fixing the flexible membrane to the sheet in which the cells are formed, the flexible membrane is pre-notched to present fragile weakening zones, and is then positioned on the sheet in which the cells are formed so that the pre-notched areas are arranged at the location of the corridors between the cells and the edge of the device, formed in the subsequent step, during the welding of the first to the second sheet .
  • the device consists of two superimposed sheets 1, 2, firmly welded to one another.
  • the first sheet 1 which is made of a thermoformable material such as for example polyvinyl chloride
  • a deformation is formed in the form of a cell 3 constituting receiving volume 4 for the dose of pasty material.
  • This first sheet also includes a conduit 5 for discharging the dose of pasty material, open at one of its ends 6 and opening at its other end 7 into the cell 3.
  • a flexible membrane 8, constituting closure means provides a separation 9 between the cell 3 and the conduit 5 and is assembled to the sheet 1 in the zone of the conduit 5 to form at this location a fragile closure.
  • the conduit 5 simply consists of an unwelded passage formed between the sheets 1 and 2.
  • the wall of the conduit 5 formed in the sheet 1 was deformed during the welding operation from the first to the second sheet to form a channel.
  • the fragile closure of the cell 3 is produced by a fragile connection between the membrane 8 and the wall of the conduit 5 formed in the sheet 1.
  • connection of the membrane 8 to the wall of the conduit 5 in the form of a firm connection and to produce, in the part of the membrane 8 constituting the separation 9 between the cell 3 and the conduit 5, a pre-notched weakening zone constituting the fragile closure of the cell 3.
  • This design of the packaging device makes it possible on the one hand to reduce the thickness of the packaging, and on the other hand to use for the second sheet, devoid of any deformation, a more rigid material than for the first thermoformable sheet. , thereby giving the packaging a better presentation when several doses are combined in the same packaging.
  • provision may be made to place the flexible membrane 8 only on a part of the cell 3 and of the passage 5 constituting the evacuation duct, and to weld the flexible membrane 8 to the first sheet 1 only in the zone of the corridor 5.
  • the membrane 8 is in fact taken up in this firm welding 11 and maintained around the entire periphery of the cell 3 as well as on the edges of the conduit 5.
