Definitions
- Device constituting packaging • for doses of pasty material and its manufacturing process.
- the present invention relates to a device constituting packaging for doses of pasty material, as well as the method of manufacturing this device.
- 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 , in the form of a cell constituting the volume for receiving the dose of pasty material, the device also comprising a conduit for discharging the dose of pasty material, open at one of its ends and opening out through its other end into the cell, as well as a flexible membrane, constituting closure means, which provides a separation between the cell and the duct, and which, in the area of the duct, is assembled to the said first sheet in which the cell is formed to constitute at this location a fragile closure.
- the second sheet has, before the said second sheet is welded to the first sheet, a second deformation, in the form of a channel constituting an evacuation duct, also directed away from the junction surface of the two sheets.
- this second deformation constituting 35 channel, directed away from the alveolus receiving the dose of pasty material allows the use of a flat membrane r, disposed at the junction plane of the first and of the second sheet and carrying out the separation between the cell and the channel arranged on either side of this junction plane.
- the object of the invention is therefore to remedy these drawbacks by producing, in a packaging of the aforementioned type, the conduit for discharging the dose of pasty material without deformation of the first and / or second sheets prior to their welding, and by forming the evacuation conduit through an area of non-welded passage-shaped, formed between the first sheet in which the cell is formed and the second sheet.
- said first sheet following its welding to the second sheet, which is a flat sheet of rigidity greater than that of the first sheet, said first sheet has a channel-shaped deformation in the non-zone welded in the form of a corridor constituting the evacuation duct, and the flexible membrane, integral with the wall of the duct formed in the first sheet, follows the deformation in the form of a channel of the latter.
- 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 fragile connection of the membrane to this so-called first leaf.
- the fragile closure formed, in the evacuation duct, by the membrane joined 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.
- the assembly thus formed a second sheet covering the first sheet, and the first and the second sheet, including the flexible membrane, are firmly welded to each other, at least in the peripheral zone of each cell. These process steps are also repeated in the process of the present invention.
- 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 is a flat sheet in advance can not form either in the first or the second sheet, no channel constituting conduit • evacuation, and further is firmly welded to the first the second sheet in the region extending between each cell and the corresponding edge of the device, leaving in the latter a non-welded passageway, coming from the cell and ending at the edge, constituting evacuation duct.
- 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 made, on the entire periphery of each cell, a 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 is firmly welded hot sheet 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 a corridor each time joining a cell at the edge of the device and constituting the evacuation duct, the heat of the weld ensuring a lasting bond between the first sheet, the membrane and the second sheet over the whole of the welded zone and producing, in the non-welded corridor, a deformation in the form of a 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-scored 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, when the first sheet is welded to the second sheet .
- - fig 1 is a view in section of a preferred embodiment of the device according to the invention
- Fig 2 illustrates the various stages of the process according to the invention, for the production of this device
- Fig 3 is a plan view of the device, on which have been materialized by hatching the areas concerned by the various welds.
- the device consists of two superimposed sheets 1, 2, firmly welded to one another.
- the first sheet 1 which is made of a thermoforable 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 membrane 8, welded to this wall, has followed this deformation, while the sheet 2 which is a flat sheet, for example of polyethylene, of rigidity greater than that of the sheet 1, has not undergone any deformation during of this same welding operation.
- 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.
- 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.
- the method of producing a package as described above is also simplified compared to the previous methods.
- the production steps according to the method of the invention are illustrated in FIG. 2. These steps, limited in the example illustrated to the production of a single cell, are as follows:
- thermoformable flat sheet 1 (fig 2a)
- a dose 1 of pasty material (fig 2c) is brought to the face of the sheet 1 away from the cell 3, a flexible membrane 8 is placed, so that it extends beyond the outline of the cell on all sides, and a weak weld 10 is made from the membrane 8 to the sheet 1, around the entire periphery of the cell (FIG. 2d) .
- a second sheet 2 is placed, of rigidity greater than that of the first sheet 1 (fig 2e) - the second sheet 2 is then firmly welded hot in 11 to the assembly of the first sheet 1 and of the membrane 8, over their entire junction surface, excluding the area occupied by the cell 3 and the passage 5 joining the cell 3 to the edge 6 ′ of the packaging, allowing it to deform at the heat, in the zone of the corridor 5, the sheet 1 and the membrane 8 which is integral therewith, to constitute a channel-shaped deformation.
- 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.
