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.
  • WO9411257A1 discloses a container including a container body and a movable cover made of cardboard, and latching means made of a unitary piece of tear resistant polymer, such as recycled polyethylene.
  • 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 is totally recyclable in the paper chain and which complies with the child-proof standards for reclosable containers.
  • Figures 1-16 show seven different embodiments of a reclosable container 10.
  • the reclosable container 10 comprises a container body 12 and at least one closing formation including a first closure element and a second closure element, engageable with each other to keep the container in a closed configuration and disengageable from each other to open the container.
  • the container bodies 12 and the closing formations have different shapes and structure.
  • the container body 12 is made of a cellulosic material and the least one of said first closure element and second closure element is made of a hydrosoluble thermoplastic material.
  • cellulosic material indicates a material primarily or completely made of cellulose, such as, paper, cardboard, cellulose pulp, and the like.
  • the container body 12 is entirely recyclable in the paper chain.
  • 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 one or more closure elements made of a hydrosoluble thermoplastic material is recyclable in the paper chain without the need of separating the closure elements of hydrosoluble thermoplastic material from the container body of cellulose material.
  • the container body 12 has an aperture 14 and a movable cover 16 of cellulosic material removably applied to the aperture 14 and movable between an open configuration and a closed configuration.
  • said first closure element and second closure element are provided, respectively, on said container body 12 and movable cover 16.
  • At least one of said closure elements of hydrosoluble thermoplastic material may be provided as a separate element fixed by water-sealing or by glue either said container body 12 or movable cover 16.
