Definitions

  • the present invention relates to a container made of cardboard and of thermoplastic polymer material, intended in particular to contain a cosmetic product.
  • thermoplastic polymer material for the manufacture of containers, it is known to manufacture the latter with walls made of cardboard, over which a thermoplastic polymer structure is overmoulded.
  • US 20100237068 discloses the manufacture of such a container with a cover that fits over the container.
  • the present invention achieves this by virtue, according to one of its aspects, of a container having: a pot having at least one cardboard-based side wall and a structure made of thermoplastic polymer material, this structure having a first annular wall defining the opening of the pot and an outer skirt concentric with the first annular wall and connected thereto, a closure cover configured to be fastened to the outer skirt of the pot.
  • cardboard-based means a sheet-form material having a certain quantity of paper fibres, in particular wood fibres.
  • the sheet-form material may have a multilayer or single-layer structure, with one or more films of plastics material on the outside for example, in order to improve certain properties, for example resistance to liquids or an oxygen barrier.
  • the double skirt provides enough stiffness and mechanical strength to withstand the closure of the cover and the mechanical stresses that may be encountered during transport for example, for example when the pot is subjected to a negative pressure during transport, which may typically range down to -800 mbar for example.
  • the outer skirt may have a radially outer surface having at least one helical thread.
  • the closure cover may have at least one helical thread for screwing the cover onto the outer skirt of the pot.
  • the pot may have a plurality of helical threads, allowing rapid closure of the cover, preferably in less than one turn.
  • the pot may advantageously have a plurality of reinforcing ribs connecting the first annular wall to the outer skirt, in particular between 6 and 30 ribs. These ribs radially connect the first wall to the outer skirt.
  • the ribs preferably extend axially over a distance less than a height of the outer skirt. This reduces the visibility of these ribs and may make it easier to stack the empty pots in the absence of a cover.
  • the pot may have a transverse annular wall connecting the first annular wall to the outer skirt.
  • This annular wall constitutes the bottom of the annular groove formed between the first wall and the outer skirt.
  • the reinforcing ribs are connected thereto, thereby further improving the mechanical cohesion of the upper part of the pot.
  • the transverse annular wall may be continuous or discontinuous. In the latter case, it has openings. This latter case may be advantageous for further reducing the quantity of thermoplastic polymer material used, without excessively compromising mechanical strength.
  • the first annular wall may have a portion extending above the transverse annular wall and thus form a sealing lip.
  • a sealing lip is advantageous for obtaining a good seal when the cover is screwed onto the pot. This makes it possible in particular to avoid the use of an attached seal made of elastomer.
  • the sealing lip may have a height of between 2 mm and 4 mm.
  • the sealing lip, the first annular wall, the outer skirt and the annular transverse wall may together form an “h”-shaped profile, the sealing lip preferably having an inside diameter substantially identical to that of the first annular wall under the annular transverse wall.
  • the seal may be obtained by providing contact of the cover with the first annular wall.
  • the opening formed by the first annular wall may be circular, in particular with a diameter greater than 5 cm, in particular between 5 and 15 cm, preferably between 7 and 12 cm.
  • the first annular wall may have a thickness less than 1 mm, preferably less than 0.7 mm.
  • the outer skirt may have the same thickness as the first annular wall, apart from the parts bearing said at least one helical thread, where appropriate.
  • the transverse annular wall and/or the sealing lip may have the same thickness as the first annular wall in its region situated under the transverse annular wall.
  • the structure made of thermoplastic polymer material preferably has a second wall situated at the base of the pot, in particular with an annular shape. This second annular wall may make it possible to improve the mechanical strength of the pot and the retention of the cardboard-based wall or walls of the pot.
  • the second annular wall and the first annular wall may be connected together by at least one post, the latter extending preferably along a generatrix of said at least one cardboard-based side wall.
  • the structure is preferably produced by a single injection-moulding operation.
  • the structure may be overmoulded over said at least one cardboard-based side wall.
  • the overmoulding of the structure over said at least one cardboard-based side wall makes it possible to form the structure with great precision, thereby avoiding the need, when the cover is fastened by screwing, to design the thread or threads allowing this screwing with a high level of flexibility in order to compensate for manufacturing tolerances. Consequently, it is easier to comply with the quality and sensoriality standards of the cosmetics industry.
  • the overmoulding is preferably effected by injection-moulding.
  • the first annular wall may be overmoulded over an upper part of the cardboardbased side wall.
  • the second annular wall may be overmoulded over a lower part of the cardboard-based side wall.
  • the cardboard-based side wall may be formed from a cardboard-based sheet wound so as to bring two of its edges together.
  • Said at least one post of the structure may be overmoulded over the cardboardbased side wall in the region in which said two edges are brought together.
  • the post makes it possible to maintain the wound shape of the cardboard-based side wall and to seal the pot along the region in which the two edges are brought together.
  • the pot may have a cardboard-based bottom.
  • the second annular wall may be overmoulded around the cardboard-based bottom.
  • Such a cardboard-based bottom may be flat. The use of such a bottom makes it possible to further reduce the quantity of thermoplastic polymer material in the pot.
  • the thickness of said at least one cardboard-based side wall and/or of the cardboard-based bottom may be between 0.5 mm and 0.7 mm. Such a cardboard thickness makes it possible to ensure that the pot has sufficient stiffness for its use for cosmetics.
  • Said at least one cardboard-based side wall and/or the cardboard-based bottom may have at least one external layer, in particular configured to improve the adhesion of the structure, in particular a layer made of thermoplastic polymer, in particular made of polypropylene (PP), of polyethylene (PE) or of polylactic acid (PLA), which is or is not biobased.
  • PP polypropylene
  • PE polyethylene
  • PLA polylactic acid
  • Said at least one cardboard-based side wall and/or the cardboard-based bottom may have at least one barrier layer formed by chromatogeny and/or chosen from the group made up of metal layers (such as a metallization), layers of ethylene vinyl alcohol (EVOH), layers of polyvinyl alcohol (PVOH), layers of silicon oxide (SiOx) and a mixture thereof.
  • metal layers such as a metallization
  • EVOH ethylene vinyl alcohol
  • PVH polyvinyl alcohol
  • SiOx silicon oxide
  • a barrier layer formed by chromatogeny is understood to mean a cardboard-based treatment which makes the paper fibres hydrophobic through the deposition of a small quantity of fatty substance.
  • the closure cover may have an outer skirt comprising at least one helical thread, said outer skirt being connected by a transverse wall to a first annular part defining a first, downwardly opening groove.
  • the sealing lip may be in contact with a radially inner surface of said first groove when the container is closed.
  • Said first groove may have an inverted U-shaped section, the closure cover preferably comprising reinforcing ribs extending into said first groove.
  • the closure cover may comprise a second annular part defining a second, upwardly opening groove.
  • Such a shape makes it possible to achieve good sealing even in the event of a relatively high negative pressure outside the pot, without using an added seal.
  • the cover may be manufactured by a process of injection-moulding a thermoplastic polymer material.
  • the pot may have a capacity of between 50 ml and 100 ml.
  • the structure of the pot may have a thermoplastic polymer material chosen from the group made up of polyethylenes (PE), polypropylenes (PP), polyethylene terephthalates (PET), polylactic acids (PLA) and a mixture thereof.
  • PE polyethylenes
  • PP polypropylenes
  • PET polyethylene terephthalates
  • PLA polylactic acids

  • the pot 2 has, in this example, a cardboard-based side wall 4 which has a slightly conical shape and over which a structure 5 made of a polypropylene (PP), visible in Figure 3, is overmoulded.
  • PP polypropylene
  • the cardboard-based side wall 4 is, in this example, formed from a cardboard sheet wound so as to bring two of its edges together.
  • the cardboard-based side wall 4 has a central, paper fibre-based layer and two external layers made of polyethylene in order to facilitate the adhesion of the structure 5 and at least one, for example metallic, barrier layer between the central layer and one of the external layers.
  • the structure 5 has a first annular wall 10 forming the opening 11 of the pot 2, for example having a diameter of 10 cm.
  • the structure 5 also has an outer skirt 12 which is concentric with the first annular wall 10 and connected to the latter by a continuous transverse annular wall 15, which, in this example, is substantially perpendicular to the longitudinal axis of the pot 2, as can be seen in Figure 4.
  • the outer skirt 12 has a radially outer surface which has, in this example, a plurality of helical threads 13 allowing rapid closure of the pot 2 in less than one turn.
  • the pot 2 also has a plurality of ribs 20 connecting the first wall 10 to the outer skirt 12.
  • the ribs 20 extend, in this example, under the transverse annular wall 15 over a distance less than a height of the outer skirt 12.
  • the first annular wall 10 extends, in this example, above the transverse annular wall 15 in order to form a sealing lip 21.
  • the sealing lip 21 has, for example, an inside diameter substantially identical to that of the portion of the first annular wall 10 extending beyond the annular transverse wall 15.
  • sealing lip 21, the first annular wall 10, the outer skirt 12 and the annular transverse wall 15 together form an “h”-shaped profile.
  • the first annular wall 10 has a thickness less than 1 mm.

  • the post 26 of the structure 5 is overmoulded over the cardboard-based side wall 4 in the region in which said two edges are brought together. This makes it possible to keep the cardboard-based side wall 4 in its wound position and to avoid the penetration of fluid into the core of the side wall 4 at said edges.
