Definitions

  • the invention relates to dispenser packaging for viscous, creamy or paste products, as well as a manufacturing method for such containers.
  • the packaging according to the invention is particularly suitable for the distribution of hygiene products or cosmetics in pasty form.
  • the cosmetic and sanitary industry has long sought relatively inexpensive packaging capable of delivering its content, without requiring the use of excessive force by the user, and which retains a pleasant external appearance until the end of their existence. .
  • Containers made of kneadable materials quickly have an unattractive appearance. Rigid containers easily regain their shape by sucking in air which replaces the paste which has just been extracted therefrom, which constitutes a drawback from the point of view of the degradation of the content and its asepsis. New forms of packaging have been developed to avoid these drawbacks.
  • US Pat. No. 4,842,165 describes a bottle with an elastic wall in which is suspended a pocket intended to contain the product to be dispensed according to the preamble of claim 1. This pocket is held at mid-height at the elastic wall. A non-return valve prevents the product from going back into the pocket after compression. A second non-return device placed in the base of the bottle allows air to enter between the bottle and the pocket when compression has ceased.
  • US-4,909,416 describes a container viscous product dispenser with an external container that can be pressed or deformed locally (accordion structure) and an internal deformable pocket connected to a spout.
  • This spout has a one-way valve preventing backflow of the contents to the pocket.
  • a second valve allows the introduction of air between the pocket and the outer container.
  • One of the aims of the invention is precisely the production and the placing on the market of a packaging distributor of viscous and pasty products which retains its shape, which is easy to produce and of low cost price.
  • Another object of the invention is that this packaging, which would only be used once, remains perfectly reliable throughout its use. Another aim is that the consumer can use it to the end without excessive grinding.
  • the subject of the invention is a dispenser packaging for a more or less pasty or viscous product comprising a dispensing head and a body, said dispensing head comprising a spout traversed by a discharge opening, closable at its end by a removable closure, and connected by its other end to a collar.
  • the body in substance tubular, develops along an axis and comprises an inner envelope and an outer envelope surrounding said inner envelope, these two envelopes being closed at one end of the body and being, at the other end, connected together and at the periphery of the collar of the dispensing head.
  • the inner envelope is more flexible than the outer envelope, devoid of elastic memory and capable of containing a pasty or viscous product.
  • the outer casing is more elastic and more rigid than the inner casing, but nevertheless deformable under the effect of a manual compressive force and capable of returning to its original shape when the compressive force ceases to be applied.
  • a non-return device prevents the passage of air from a volume between the outer envelope and the inner envelope, towards the outside, when the outer envelope is compressed, but allows the passage of ambient air to this volume when compression ceases to be applied.
  • the body comprises two joined envelopes, these envelopes being joined and merged with the flange of the dispensing head, and thus maintained at the level of said flange and at at least two points at the end opposite to said dispensing head.
  • the assembly formed by the middle layer and the outer layer form an outer envelope having greater rigidity than the inner envelope constituted by the inner layer.
  • the end of the tubular body opposite the dispensing head is closed by a weld.
  • the end of the tubular body opposite the dispensing head is secured to the periphery of the collar of a base.
  • the middle layer and the inner envelope are advantageously formed from a single sheet in the form of a sleeve, flattened in substance along a plane, then rolled up on itself.
  • the middle layer and the inner envelope are formed from a single sheet of substantially planar material, folded over itself in the width direction, said folded sheet being wound on itself parallel to the axis of the body, its two longitudinal edges being attached to the fold of said sheet.
  • the at least one sheet of material forming the middle layer and the inner envelope is wound on itself by at least one turn inside the outer layer, its longitudinal edges being secured, by an axial weld, on the surface of the adjacent sheet.
  • the at least one sheet of material is preferably wound around itself by about a half turn inside the outer layer in the form of a sleeve.
  • the non-return device advantageously comprises at least one orifice in the external envelope, a valve disposed on the internal face of the external envelope opposite said at least one orifice, a zone where the external envelope and the internal envelope are not secured surrounding said at least one orifice and said valve.
  • the non-return device can also comprise at least one orifice drilled in the outer envelope, and at least one orifice drilled in the middle layer, the surface covering flexible material between these orifices forming non-return valve, an area in which the outer casing and the middle layer are not secured surrounding said valve.
  • Another advantage is the low volume of raw materials required for manufacturing.
  • Another advantage lies in the ease of changing the manufacturing parameters, given the simplicity of the manufacturing process.
  • Another advantage is the possibility of variations in possible shapes.
  • Another advantage is that the design of the packaging ensures good maintenance of the inner envelope which empties without the formation of residual pockets.
  • weld 9 could be replaced by a line of adhesive (or any other means known to those skilled in the art) without departing from the scope of the invention.
  • Fig. 2 shows the same packaging in its completed form.
  • the collar 4 is connected to the tubular body 6 and thus hermetically closes the volume determined by each of the envelopes 7, 8 making up the body 6, it is noted that at the terminal stage, the collar 4 is completely merged with the two external envelopes 7 and internal 8.
  • the other end of the tubular body 6 is closed by a weld 10 which fixes all of the layers together, both the layers forming the internal envelope and the layers forming the external envelope 7.
  • FIG. 3 shows the packaging l in section at the height of the valve 12. The thicknesses of the walls have been deliberately accentuated.
  • the ends of the envelopes 7, 8 are sealed together, hermetically with respect to one another by the longitudinal weld 9.
  • the internal envelope 8 determines with the flange 4, on the one hand, and with the transverse weld 9, on the other hand, a volume ("internal volume") which will be occupied by the pasty product for which the packaging is intended.
  • a second volume also extends, delimited on either side by the flange 4 and the transverse weld. 10.
  • This second volume initially reduced, when the packaging is full, contains air and communicates with the atmosphere through the opening 11.
  • a valve 13 closes this opening 11 - unidirectionally - so that the air presses on the valve 13 and cannot escape towards the outside when the packaging is compressed, but can return easily when this pressure ceases.
  • this device is simple: when the contours of the external envelope 7 are pressed, the air trapped in the external envelope 7 compresses the internal envelope 8 and causes the expulsion of a determined quantity of product pasty.
  • valve 12 can be replaced, according to the desired performance, by any other non-return device, preferably inexpensive.
  • any other non-return device preferably inexpensive.
  • the pocket formed by the internal envelope 8 is reduced accordingly. It is however held in place all along by the longitudinal weld 9 and by gluing zones which do not, however, retain more than half of its surface, so as to allow a gradual withdrawal and as complete ejection of the product as possible. pasty it contains and avoid obstruction of the spout 2 by the formation of a pocket in the inner wall.
  • the method of manufacturing a package as described above is quick and inexpensive and its elements are found in the figures described.
  • a first form of process one starts from sheets of materials having two different rigidities 16, 17 (by their nature or by their thickness). For continuous production, these sheets are generally removed mechanically from rolls with continuous unwinding. After superposition, the sheets 16, 17 are wound on themselves and welded to form a tubular sleeve 18 (Fig. 6). It is also possible to glue the two sheets 16, 17 over at least part of their perimeter.
  • the sections are cut to length and a non-return device 12 is inserted or arranged in the body 6. A welding or sizing at the end allows the insertion of the flange 4 supporting the spout 2 on the body 6.
  • the packaging is finished by pinch welding on the other end 10 of the body or its insertion on a base.
  • a single sheet 19 (Fig. 8), of plastic for example, which, for manufacturing, is first folded back on itself and glued between two folds, so forming a thicker and more rigid composite outer layer.
  • This single folded sheet 19 is used as a superposition of sheets, wound on itself and welded to form a sleeve as described above.
  • a glued sheet reacts better than an identical sheet with double thickness would react.
  • the adhesive layer 20 in fact also participates, by its intrinsic mechanical properties and by its thickness, in the properties of the envelope.
  • Figs. 4 and 8 to 11 show different ways of arranging the sheets to produce the body of a package according to the invention.
  • Fig. 4 shows, in perspective, a stack comprising a flexible sheet 16 and a more rigid sheet 17, in this case of substantially rectangular shape.
  • These sheets 16, 17 have two longitudinal sides 21, 22 and two transverse sides 23.
  • a securing means 20 glue, in this case
  • the non-return device 12, as it appears in section in FIG. 7, here comprises a valve 13 closing the orifice 11 drilled in the most rigid layer 17.
  • the longitudinal sides 21, 22 are brought together so as to obtain the successive configurations shown in FIGS. 5 and 6, and finally a tubular shape 18.
  • the two edges in contact 21, 22 are joined to maintain this shape.
  • Fig. 8 shows another starting point for producing, according to the same process, packaging as described above.
  • a single sheet 19, of uneven thickness, is folded in two along a longitudinal axis.
  • Two superimposed layers 24, 25 of different rigidity are obtained.
  • the two layers 24, 25 are partially glued (while retaining their relative freedom over at least 50% of their surface).
  • a valve 13 is inserted on the most rigid layer 24, at the level of an orifice 11 so as to produce a non-return device 12.
  • the double fold necessary for the formation of the two envelopes 7, 8 can also be obtained by flattening, roughly along a plane, a section of hose made in the appropriate material or materials. This flattened hose is then folded back on itself, as shown in Figs. 5 and 6 to form a new tubular body 18.
  • Figs. 9 and 10 illustrate the possibility of making a packaging body from a sheet 32, 33, 34 folded in two folds on itself, so as to obtain three layers 32, 33, 34 of superimposed material.
  • perforations 11, 35 Prior to folding, perforations 11, 35 are produced on two of the folds, arranged so as not to come opposite one another, as seen in FIG. 12.
  • the tongue 36 of flexible material separating these two perforations 11, 35 performs the function of a non-return valve 12, further improved by the bending which occurs during the manufacture of the body 6 of the packaging.
  • the shape and dimensions of the holes 11 and 35 depend on the rigidity of the plastic used.
  • the fold 32 intended to be turned towards the outside and the median fold 33 are secured, by gluing 20 for example (with the exception of the area surrounding the perforations), so as to obtain a "double" wall, more rigid than the "simple" layer of the inner envelope 34 and which therefore functions perfectly according to the principle of the invention.
  • the folding can be done in a Z as in FIG. 9 or in cross folds as in FIG. 10.
  • Fig. 11 You can still combine the material sheets in different ways.
  • two sheets 37, 38 of different materials are used: a sheet 37 of more rigid material and a sheet 38 of more flexible material, the latter folded in half.
  • the first envelope is obtained by joining the first sheet 37 and one of the folds of the second sheet 38, by making the non-return device 12 according to the method described above.
  • the second envelope 8 is produced by joining the longitudinal edges of the second sheet 38. The whole is wound as described above (Fig. 5, 6) to form the body 6 of the package.
  • Fig. 13 shows the section of a coiled body using a structure as described in FIG. 11. As can be seen, it is possible, during the superposition, to slightly offset the sheets 37, 38 relative to each other, which makes it possible in particular to produce saving material and improving the technical qualities of the packaging.
  • Figs. 14 and 15 illustrate embodiments of the body of the packaging claimed in the present divisional application.
  • the body of the package shown in Fig. 14 comprises an internal envelope 8, a middle layer 39 made of the same material as the internal envelope 8, according to any of the techniques described above, and an external layer 40 without discontinuity, the assembly formed by the layer outer 40 and the middle layer 39 forming an outer envelope 7 having greater rigidity than that of the inner envelope 8.
  • the inner envelope 8 and the middle layer 39 are formed by the folds 8, 39, of the same sheet original folded in half and thus wound on itself so as to form a tubular sheath.
  • the two longitudinal edges of the original sheet 8, 39 are welded to its central fold 42, so that the two folds 8, 39 determine two almost concentric volumes, isolated from each other.
  • the outer layer 40 which continuously contains the entire body 6 of the package.
  • the outer layer 40 is for example extruded around the tubular sheath and glued to it, excluding a reserved area 43 necessary for the production of a non-return device 12, and which extends around the orifices 11, 35.
  • Fig. 15 shows a particular embodiment based on the same principle.
  • a sheet of flexible material that we roll on itself for about one and a half turns.
  • Each longitudinal edge 41 is welded to the surface which is adjacent to it.
  • Two envelopes 7, 8 are thus obtained which have a common wall 44 which is part of both the "internal" envelope 8 and the "external" envelope 7.
  • the outer layer 40 is extruded around this assembly to form with the middle layer 39, the outer envelope 7 of the package.
