Definitions

  • the present invention concerns a capsule made of a paper material that can be used for dispensing drinks, for example coffee, tea, fruit juices and/or the like.
  • the capsule made of paper material can be used both privately and commercially in appropriate machines/dispensers for dispensing coffee and/or like drinks.
  • the capsules are essentially rigid containers inside which powder products are inserted, such as coffee and/or tea and/or milk and/or the like.
  • the capsule is inserted internally of special dispensers, such as coffee machines, which enable the capsule contents to be mixed with hot water and then dispense the desired drink.
  • the dispensers enable a perforation of the capsule to be made on a side thereof and water to be injected therein which is to be mixed with the powdered substance present inside and enables release of the flavour; the drink then exits from further perforations made on the other side of the capsule and is directed toward the cup/container for consumption.
  • the capsule is a substantially rigid container of a small size (different to a pod because the pod is made of a non-rigid paper filter) having a substantially cylindrical shape closed at both ends and made generally of a plastic and/or aluminium material.
  • Coffee capsules are known that are closed at an end by a filter that allows the passage of the liquid during the injecting of water by the coffee machine, while preventing the outflow of the substance in powder form.
  • coffee capsules can be closed at one end by a film of plastic and/or aluminium. During the insertion of the capsule in the coffee machine, the coffee machine creates the perforations at both ends, respectively useful for the entry of water and the outflow of the beverage.
  • a first example described in document WO 2010/055 469 Al, relates to a capsule for dispensing aromatic products such as coffee.
  • the capsule consists of a base which is coupled to a lateral wall.
  • a cover is applied on the top of the lateral wall, in particular at an end of the lateral wall opposite the base with respect to the lateral wall thereof. In this way the base, the lateral wall and the cover delimit the internal volume of the capsule.
  • the base and the lateral wall are two separate parts which are joined and sealed to each other by a suitable glue.
  • the above-described capsule has several drawbacks and limitations.
  • the structure of the capsule requires several stages of production for obtaining the final product.
  • the capsule requires a step of coupling between the base and the lateral wall, which contributes to weakening the structure and to increasing the production time with a consequent increase of costs.
  • additional material in particular the glue, for the coupling between the base and the lateral wall, leads to an increase in the cost of the product.
  • glue also involves additional problems, since this must not come into contact and thus contaminate the drink.
  • a second example, described in WO 2007/126608 A2, relates to an apparatus and a method for the production of coffee capsules made of paper material.
  • the apparatus comprises a base able to receive a sheet material and a pressure tool hinged to the base.
  • the base and the pressure tool respectively have a seating and a protrusion having a substantially circular shape and are respectively complementarily shaped.
  • the sheet material is constituted by a first and a second portion coupled to each other and both having a substantially circular starting shape.
  • the first and second portions are coupled together so as to define a template having a figure-of-eight shape.
  • a flavouring substance is positioned internally of the container and thereafter the container is closed by folding the second portion (which can maintain a substantially flat shape) on the first portion so as to define a capsule.
  • the second portion is maintained in contact with the first portion and joined by means of adhesive material.
  • the container of the capsule can be obtained starting from a sheet material in a single piece although the geometry obtainable without tearing the paper is not clear.
  • the step of assembly of the container is eliminated, but the process appears to be entirely manual and not industrialisable.
  • the capsule described in the second example does not require the assembly step of the base to the lateral wall of the container, it does however exhibit some limits in any case.
  • a third example, described in the document US 6,189,438 Bl, relates to a capsule, or filter element, for dispensing beverages and a relative manufacturing method for the realisation of the capsule.
  • the filtering element is constituted by a rigid support structure having a curved form and defining a hollow container.
  • the support structure has an upper opening defined by the external perimeter of the arched portion: this opening also defines the inlet which allows entry of water into the capsule.
  • the support structure is configured so as to internally accommodate a container that is substantially complementarily shaped to the support structure, made of paper material within which a powder solution is contained that is suitable for mixing with the water and generating the beverage.
  • the container is formed from a flat sheet of paper material having a substantially circular shape.
  • the flat sheet is deep drawn so as to define the container having the arched shape.
  • the drawing of the flat sheet generates, on the lateral wall of the container, pleat shapes that are substantially uniform throughout the development of the lateral wall, which compensate for the surplus of material generated by the pleating of the flat sheet into the three-dimensional form.
  • the capsule described in the third example has several limitations.
  • the domed structure of the paper container means that it cannot provide any structural support: in fact the capsule requires an additional support structure able to support the rigid outer paper powder container, which greatly increases product costs.
  • a first objective is to disclose a capsule that is easy to realise and thus has low production costs.
  • a further auxiliary aim is to provide a capsule made of paper material able to contain the powder substance present internally thereof.
  • An aim is to provide a capsule for preparing drinks can enable indicating the content, thus being differentiated by a capsule for preparing a different drink.
  • an additional aim is to prevent any contact between the drink (water, food powder and water plus flavourings) with eventual substances (for example, colorants, lacquers or paints) which differentiate the capsules from one another.
  • a further particular objective is to enable passage of water crossing the capsule without any need for always perforating both the upper and lower inlet walls.
  • An additional objective is to provide a capsule which is without glues or adhesives while guaranteeing the containing of the food substance.
  • a secondary objective is to obtain a capsule having improved rigidity in relation to the deformations of the lateral wall thereof.
  • a possible objective is to improve the content of the food substance, possibly facilitating the mixability thereof with the crossing water.
  • a further additional aim is to improve the final aspect of the product following production thereof by deep drawing.
