    DESCRIPTION
    Lid for containers of hot dosed product and device for manufacturing.
    Object of the invention.
    The present invention relates to a lid for hot dosed product containers and device for its manufacture from a sheet of flexible material continuously supplied to a fixing area of said lid to a container containing a hot dosed product.
    This invention has constructive particularities oriented to allow a contraction of the lid into the container during cooling of the hot dosed product, preventing said deformation from affecting the container.
    Field of application of the invention.
    This invention is applicable in the field of hot dosed products packaging and especially although not limited to hot dosed food products.
    State of the art.
    Currently, it is a common practice, especially within the food sector, to pack hot-dosed food by almost immediately closing the container by means of a lid consisting of a more or less flat sheet of flexible material and dimensions according to the mouth of the container.
    For obvious reasons of production, it is also usual to package these products in multiple packages to form the typical packs, closing these containers simultaneously by means of a sheet of flexible material that is fixed simultaneously on the mouths of each and every one of the packages

    pack conformers.
    These containers once filled with a hot dosed material, for example chocolate or other food products, and closed the container with the flat lid of flexible material, during the cooling of the product a vacuum is generated inside the package that causes deformation from the lid and / or the container to the inner cavity containing the product.
    When the lid is contracted into the container, it defines a concave curved outer surface that deteriorates the final presentation of the product.
    The deformation of the lid towards the surface of the mouth of the container due to the vacuum caused during the cooling of the packaged product causes that the forming sheet of the lid is subjected to an overvoltage being necessary to calculate the deformation of the lid based on the characteristics of the container and the product to be packaged. The mechanism allows adjusting to these needs both in the set of packs and individually as required by each container when filled and cooled.
    The applicant of the present invention is unaware of the existence in the market of caps for hot-dosed product containers, formed from a sheet of flexible material and that allow the problem described above to be satisfactorily resolved.
    Description of the invention.
    In order to solve the aforementioned drawbacks, the lid for hot-dosed product packages object of this invention has been devised, and a device for manufacturing said lid from a sheet of flexible material continuously supplied to a container closing zone hot dosed product containers.
    The lid of this invention, comprising a sheet of flexible material, of lower consistency than the material of the container to be closed, and having a face

    inside, oriented towards the inside of the container and an outer face oriented towards the outside of the container, has the particularity of comprising a perimetral fixing portion to the mouth of a container, and a central closing portion of the mouth of the container; said central portion having at least one convex curved deformation towards the outside of the lid; said deformation defining on the side corresponding to the inner face a space of contraction of the lid towards the surface of the mouth of the container during cooling of the hot dosed product.
    The mentioned convex curved deformation allows, once the packaged product has cooled, the lid adopts a more or less flat configuration and is not subjected to an overvoltage, which allows to reduce the sheet thickness of the material used in approximately 25% The fabrication of the container body, usually: polystyrene (PS), polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), polylactic acid (PLA), polyvinyl chloride (PVC), etc.
    This invention also includes a lid manufacturing device mentioned above, from a sheet of flexible material continuously supplied to a closing area of container containers of a hot dosed product.
    This device comprises a forming head operated by a pneumatic press and arranged in a passage zone of the flexible material sheet towards the closing zone of the packages; said forming head comprising at least one treadmill and a forming punch that move longitudinally towards a fixed support; and a fixed support provided with a perimeter support and fixing surface, by the corresponding treadmill, of the flexible sheet by an area corresponding to the perimeter portion of the cover to be formed; and an introduction cavity of the forming punch during the definition of at least one convex curved deformation in an area of the flexible sheet corresponding to the central portion of the cover to be formed.
    Obviously this device can be equipped with a variable number of

    footsteps and forming punches to simultaneously manufacture several equal caps for application on a group of containers forming a product pack, with regulation of the deformation of the lid, to achieve greater perfection in the necessary deformation of each package.
    Description of the figures.
    To complement the description that is being made and in order to facilitate the understanding of the features of the invention, a set of drawings is attached to the present specification in which, with an illustrative and non-limiting nature, the following has been represented:
    - Figure 1 shows a top plan view of an embodiment of the lid for hot dosed product packages according to the invention.
    - Figure 2 shows an elevation view of the cover sectioned longitudinally by the plane AA 'referenced in Figure 1.
    - Figure 3 shows a cross-section of the lid fixed on a container containing a hot dosed product moments before placing the lid
    - Figure 4 shows an analogous view to the previous one once the product contained in the package has cooled and the lid contrasts due to the vacuum created inside the package during the cooling of the product.
    - Figures 5, 6 and 7 show elevational views of an embodiment of a lid manufacturing device provided with a multiple forming head, sectioned by a vertical plane and in different operating positions.
    Preferred embodiment of the invention.
    As can be seen in the embodiment shown in Figures 1 and 2, the lid (1) for containers (2) of hot dosed product (P) comprises a
