Abstract
A package includes a support and a closing film. The support has a supporting portion that receives a product, a perimetral edge surrounding the supporting portion, a gripping portion extending away from the opposite side of the supporting portion, a removable portion extending from the supporting portion. The closing film engages a portion of the perimetral edge and, with the support, defines a housing compartment for the product. The closing film comprises a first film portion engaged with the removable portion and a second film portion engaged with the gripping portion. When the package is opened, the removable portion at least partly separates from the support together with the first film portion and the second film portion remains engaged with the gripping portion of the support.
Claims19
A package for containing at least one product, said package comprising:
- a support exhibiting:
- a supporting portion configured to receive one or more products,
- a perimetral edge entirely surrounding the supporting portion,
- a gripping portion of the perimetral edge, extending oppositely to the supporting portion;
- a removable portion of the perimetral edge, also extending oppositely to the supporting portion;
- a closing film engaged at least with a portion of the perimetral edge and configured to define—cooperatively with the support—a compartment to house the product, said closing film comprising:
- a first film portion engaged with the removable portion, said removable portion being configured to be separated at least partially from the support along with the first film portion while the package is opened,
- a second film portion engaged with the gripping portion of the support, said second film portion being configured to remain engaged with the gripping portion of the support the package is opened,
- wherein the second film portion is:
- separated from the first portion of the closing film, or
- joined to said first portion by a weakening portion of the same closing film, said weakening portion being configured to ensure the separation of the first and second portion of the closing film while the package is opened.
A process of making a package, wherein:
- the package comprises:
- a support exhibiting:
- a supporting portion configured to receive one or more products,
- a perimetral edge entirely surrounding the supporting portion,
- a gripping portion of the perimetral edge, extending oppositely to the supporting portion;
- a removable portion of the perimetral edge, also extending oppositely to the supporting portion;
- a closing film engaged at least with a portion of the perimetral edge and configured to define—cooperatively with the support—a compartment to house the product, said closing film comprising:
- a first film portion engaged with the removable portion, said removable portion being configured to be separated at least partially from the support along with the first film portion while the package is opened,
- a second film portion engaged with the gripping portion of the support, said second film portion being configured to remain engaged with the gripping portion of the support the package is opened,
- wherein the second film portion is:
- separated from the first portion of the closing film, or
- joined to said first portion by a weakening portion of the same closing film, said weakening portion being configured to ensure the separation of the first and second portion of the closing film while the package is opened;
- and
- said process comprises:
- moving a sheet material along a predetermined advancement path, said sheet material comprising:
- a supporting portion configured to receive one or more products,
- a closing portion entirely surrounding the supporting portion,
- performing at least one incision on the closing portion of the sheet material adapted to define said removable portion,
- positioning at least one product on the supporting portion of said sheet material,
- following positioning the product on the sheet material, constraining a closing film to the closing portion of the sheet material so that the product is positioned inside a housing compartment defined by the closing film constrained to said sheet material,
- performing at least one incision of the closing film engaged with the closing portion of the sheet material to define the first and second film portions respectively engaged with the removable portion and the gripping portion of the support.
An apparatus for making a package wherein:
- a package comprising:
- a support exhibiting:
- a supporting portion configured to receive one or more products, a perimetral edge entirely surrounding the supporting portion, a gripping portion of the perimetral edge, extending oppositely to the supporting portion;
- a removable portion of the perimetral edge, also extending oppositely to the supporting portion;
- a closing film engaged at least with a portion of the perimetral edge and configured to define cooperatively with the support a compartment to house the product, said closing film comprising:
- a first film portion engaged with the removable portion, said removable portion being configured to be separated at least partially from the support along with the first film portion while the package is opened, a second film portion engaged with the gripping portion of the support, said second film portion being configured to remain engaged with the gripping portion of the support the package is opened, wherein the second film portion is:
- separated from the first portion of the closing film, joined to said first portion by a weakening portion of the same closing film, said weakening portion being configured to ensure the separation of the first and second portion of the closing film while the package is opened;
- wherein the apparatus being configured for, moving a sheet material along a predetermined advancement path, said sheet material comprising a supporting portion configured to receive one or more products, a closing portion entirely surrounding the supporting portion, performing at least one incision on the closing portion of the sheet material adapted to define said removable portion, positioning at least one product on the supporting portion of said sheet material, following positioning the product on the sheet material, constraining a closing film to the closing portion of the sheet material so that the product is positioned inside a housing compartment defined by the closing film constrained to said sheet material, performing at least one incision of the closing film engaged with the closing portion of the sheet material to define the first and second film portions respectively engaged with the removable portion and the gripping portion of the support;
- a conveyor configured to move the sheet material along a predetermined advancement path,
- a second supplying assembly configured to deliver the closing film,
- a packaging station configured to receive the sheet material on which one or more products and at least one portion of said closing film are housed, said packaging station being configured to fluid tightly engage the closing film to the sheet material,
- at least one first incision station placed upstream of the packaging station with respect to the advancement path of the sheet material and which is configured to incise the latter,
- at least one second incision station placed downstream of the packaging station with respect to the advancement path of the sheet material and which is configured to incise at least a portion of the closing film engaged on the sheet material.
