Definitions

  • the present invention relates to containers, in particular to containers for household products.
  • the invention was developed in particular in view of its application to containers for laundry and dishwasher detergents, in particular detergent pods.
  • containers made from paper materials have limitations regarding re-closable closures.
  • paper materials, whether cellulose pulp, paper, or cardboard do not have the same elasticity as plastics, and re-closable closures made from these materials cannot achieve the same functions as those achieved using plastic material.
  • opening and closing operations tend to bend and wear out the closure elements, which after a short time are no longer capable to ensure an effective closure.
  • WO2016/207849 discloses a thermoplastic composition made of cellulose and a hydrolysable or hydrosoluble polyhydroxylated polymer which is water-soluble.
  • a container made of this material would be recyclable in the paper chain as it would dissolve in water and the residue after dissolution consists of cellulose.
  • water-soluble plastic materials are not suitable for producing containers for household products such as detergent pods, detergent powders, and the like.
  • containers of household products are often stored in kitchen and bathroom compartments and are often exposed to moisture and water, which would rapidly deteriorate the containers.
  • the user may grasp such containers with wet hands, which would leave sticky residues on the hands of the user and would deteriorate the parts of the containers which have been in contact with water.
  • water-soluble plastic materials have a plastic-like appearance, which may confuse the user about the correct way of conferring to the recycling waste collection.
  • containers made of water-soluble plastic materials must not be disposed of in the plastic chain as they would pollute the plastic recycling chain, contrary to a first and immediate evaluation that could lead the user to a disposal as plastic.
  • water-soluble plastic materials are expensive and would substantially increase the packaging costs as compared to the costs of paper packaging.
  • An object of the present invention is to provide an eco-sustainable container for household products which overcomes the problems of the prior art.
  • the present invention aims to provide a container that is entirely recyclable in the paper chain and has an appearance and a tactility that spontaneously induces the consumer to the correct option of conferring.
  • An additional object of the present invention is to provide a container which complies with the child-proof standards for reclosable containers.
  • Figures 1-13 show six different embodiments of a reclosable container 10.
  • the reclosable container 10 comprises a container body 12 made of a cellulosic material and having a container aperture 14.
  • the reclosable container 10 comprises a movable cover 16 made of a hydrosoluble thermoplastic material applied to the container aperture 14 and movable between an open position and a closed position.
  • cellulosic material indicates a material primarily or completely made of cellulose, such as, paper, cardboard, cellulose pulp, and the like.
  • hydrosoluble thermoplastic material indicates a material suitable to be submitted to common methods of heat forming, or thermoforming, of thermoplastic materials, and which dissolves in the presence of water.
  • An example of a hydrosoluble thermoplastic material is disclosed in WO2016207849A1 which relates to a material formed by a combination of cellulose with a thermoplastic material comprising a hydrolysable or hydrosoluble polyhydroxylated polymer.
  • the hydrosoluble thermoplastic material disclosed in WO2016207849A1 is marketed under the trade name "PolyPaper” by NextMaterials Srl, Milano, Italy.
  • a remarkable feature of a hydrosoluble thermoplastic material according to WO2016207849A1 is that it is entirely recyclable in the paper chain. Therefore, a container including a container body 12 of cellulose material and a cover 16 made of a hydrosoluble thermoplastic material is recyclable in the paper chain without the need of separating the cover 16 of hydrosoluble thermoplastic material from the container body 12 of cellulose material.
  • the reclosable container 10 comprises a support frame 18 made of a hydrosoluble thermoplastic material.
  • the support frame 18 is fixed to an outer surface 20 of the container body 12 and surrounds the container aperture 14.
  • the support frame 18 may be fixed to the outer surface 20 of the container body 12 by water sealing or by glue.
  • Water-sealing is a property of "Polypaper" which, having a PVOH matrix, partially melts in contact with water and can be bonded to cellulose-based materials.
  • the support frame 18 has a frame aperture 22 overlapped to the container aperture 14.
  • the movable cover 16 is hinged to the support frame 18 along a hinge axis 24 and is pivotally movable about the hinge axis 24 between an open position and a closed position.
  • the movable cover 16 may be formed by a flat panel having panel edges 26 which in the closed position abut against respective aperture edges 28 of the support frame 18 to prevent the movable cover 16 from being pushed inside the container body 12.
  • the support frame 18 and the movable cover 16 comprise respective first and second closure elements integrally formed with the support frame 18 and with the movable cover 16 and cooperating with each other to retain the movable cover 16 in the closed position.
  • the first and second closure elements may comprise mutually cooperating teeth 30 and slot 32.
  • one or more flexible teeth 30 are integrally formed on an edge of the frame aperture 22 and are configured for engaging a corresponding slot 32 set on a corresponding edge of the flat panel forming the movable cover 16.
  • the flexible teeth 30 and the slots 32 are provided on respective ribs 34, 36 projecting from the flat panel forming the movable cover 16 and from the support frame 18. In the closed position, the flexible teeth 30 snap engage into the corresponding slots 32 and retain the movable cover 16 in the closed position.
  • the container body 12 may be formed by a cardboard box. In the embodiment of figure 5 the container body 12 may be formed by a flexible paper bag.
  • the movable cover 16 is substantially U-shaped and comprises a flat central wall 38 and a pair of lateral walls 40 perpendicular to the flat central wall 38.
  • the flat central wall 38 is hinged to the container body 12 along a hinge axis 24 extending along an edge of the container aperture 14 and along an edge of the flat central wall 38.
  • the lateral walls 40 have respective hook formations 42 at the respective distal ends, which are configured to engage respective edges of the container aperture 14 in the open position to retain the movable cover 16 in an inclined open position.
  • the container body 12 may comprise a flap 44 of cellulosic material connected to a wall of the container body 12 along a folding line set on an edge of the container aperture 14.
  • the flat central wall 38 of the movable cover 16 is overlapped and fixed to the flap 44, so that the folding line between the flap 44 and the wall of the container body 12 forms the hinge axis 24 around which the movable cover 16 is pivotally movable.
  • the flat central wall 38 may be fixed to the flap 44 by water sealing or by glue.
  • a strip 46 of hydrosoluble thermoplastic material may be fixed, e.g. by water sealing or by glue, to an outer surface of the container body 12 adjacent to an edge of the container aperture 14 opposite to the hinge axis 24.
  • the movable cover 16 may comprise one or more teeth 30 integrally formed on an edge of the flat central wall 38, which in the closed position of the movable cover 16 engage an edge of the strip 46 to retain the movable cover 16 in the closed position.
  • the movable cover 16 comprises a flat panel 48 made of hydrosoluble thermoplastic material, slidable on the outer surface 20 of the container body 12 along a longitudinal direction A.
  • the reclosable container 10 comprises a pair of straight guide sections 50 made of hydrosoluble thermoplastic material, fixed to the outer surface 20 of the container body 12, e.g. by water sealing or by glue.
  • the straight guide sections 50 are parallel to the longitudinal direction A and extend outside of the container aperture 14.
  • the flat panel 48 is slidably movable between the straight guide sections 50 along the direction A between an open position and a closed position.
  • the straight guide sections 50 may be joined to each other by a transverse section 52.
  • the flat panel 48 comprises two flexible engagement teeth 54 integrally formed with the flat panel 48. In the closed position of the flat panel 48 the flexible engagement teeth 54 engage respective slots 56 formed in end portions of the straight guide sections 50 and retain the flat panel 48 in the closed position.
  • the container body 12 has a cylindrical shape and the container aperture 14 is formed at an open top end of the container body 12.
  • the movable cover 16 is detachable from the container body 12 and comprises a cover top wall 56 and a cylindrical cover side wall 58 which engages into the container aperture 14.
  • the cover side wall 58 comprises at least one flexible engagement tooth 60 integrally formed with the cover side wall 58.
  • the at least one flexible engagement tooth 60 in the closed position of the movable cover 16 engages a respective through window 62 formed in the top end of the container body 12 to retain the movable cover 16 in the closed position.
  • the cover side wall 58 of the movable cover 16 has two flexible engagement teeth 60 diametral opposite to each other, which engage respective through windows 62.
  • the container body 12 may comprise L-shaped formations 64 of hydrosoluble thermoplastic material fixed, e.g. by water sealing or by glue, on upper edges of respective through windows 62, to prevent damages to the edge of the through windows 62 during repeated opening and closing of the container.
  • the movable covers 16 of hydrosoluble thermoplastic material are only a small fraction of the total surface of the container body 12 and are therefore less prone to degradation when the container is exposed to water or moisture as compared to containers entirely made of hydrosoluble thermoplastic material.
  • the movable covers 16 necessitate relatively small quantities of hydrosoluble thermoplastic material and therefore do not increase in a substantial way the cost of the container.
  • the movable covers 16 may ensure compliance with child-proof closure standards without compromising the recyclability of the containers in the paper chain.
