Definitions

  • the present invention relates to a package-sealing device that avoids air from entering the package after the package is opened for the first time.
  • Tetra Brik® A common example of this type of packaging is the so-called Tetra Brik®.
  • packages with an articulated closing element were designed so that a tab, which covered an opening, had to be removed in order to open the package for the first time, and said articulated closing element then allowed sealing the opening.
  • the sealing device of the invention resolves the aforementioned drawbacks and has other advantages that are described below.
  • the package-sealing device is characterized in that it comprises a sealing element provided with an outlet, the walls of the outlet being in contact with each other, making it close.
  • the package-sealing device comprises a closing element, and the sealing element is made up of a flexible sheet, being said sealing element partially attached to the closing element, such that the sealing element deforms when the closing element is removed, thus defining an outlet and closing it, when the walls of the outlet are in contact with each other.
  • said sealing element is attached to the closing element in a central area of said sealing element.
  • said sealing element is a sheet of plastic material, specifically, a sheet of polyethylene.
  • said closing element is a tab and is positioned over said sealing element.
  • the package-sealing device according to the present invention may also comprise at least one restraint flap which retains the outlet formed by said sealing element, being said flap or flaps advantageously resilient.
  • the package-sealing device according to the present invention also comprises a lid, which, in its closed position, is placed over said closing element and said sealing element.
  • said lid is articulated with regard to a frame that can be attached to a package.
  • the outlet of said sealing element is made of an elastomer, for example, silicone.
  • the package-sealing device avoids air from entering the package, because the sealing element prevents it from doing so. This is possible because the flexible sheet, which forms the walls of the outlet, maintains contact of the wall surfaces thus avoiding air from entering and when contents are to be removed from within the package, the flexible nature of the sheet allows the outlet to open, separating the walls of the outlet due to the passage of the product.
  • FIGS. 1 to 3 are perspective views of the package-sealing device according to the present invention showing the removal of the closing element and the forming of the outlet;
  • FIG. 4 is a perspective view of a second embodiment of the package-sealing device according to the present invention in its position of use.
  • FIG. 5 is a perspective view of a third embodiment of the package-sealing device according to the present invention.
  • FIGS. 1 to 3 show a first embodiment of the sealing device according to the present invention.
  • a package 7 for example a Tetra Brik® type package, comprises an opening 8 through which the contents of the package can flow, for example, a beverage or some kind of liquid food.
  • a closing 1 element is placed over this opening 8 such as, for example, a tab, which can be pulled for removal.
  • a sealing 2 element is positioned, with is formed of a flexible sheet, for example a sheet of plastic material, advantageously polyethylene.
  • This sealing 2 element is partially attached, for example in its central part, to a closing 1 element, as can particularly be seen in FIG. 2 .
  • This coupling may be performed in any suitable manner, for example, by means of heat sealing.
  • Said outlet 3 will close automatically due to the characteristics of the sheet that forms it, for instance, due to the static electricity generated by the sheet of plastic material, making the wall surfaces contact each other, and preventing the air from entering into the package.
  • the package-sealing device comprise a lid 5 , which is preferably articulated with regard to a frame 6 attached to the package 7 around the opening 8 .
  • the contents of the package 7 have to be delivered, for example a liquid
  • this can be achieved in a conventional manner by rotating the package until the content flows from the outlet 3 , which will open automatically due to the pressure exerted by the content as it flows out of the package 7 , and will then close again automatically.
  • the user will not have to manipulate the sealing device in a way that is different from current use, since the sealing 2 element interacts with the closing 1 element when opening the package for the first time and later with the content of the package 7 when opening the outlet 3 .
  • FIG. 4 also shows an alternative embodiment with regard to the one appearing in FIGS. 1 to 3 .
  • the same reference numbers are used to identify equivalent elements.
  • restraint 4 flaps may have any suitable shape, not necessarily that shown in FIG. 4 .
  • FIG. 5 shows a third embodiment of the package-sealing device according to the present invention.
  • the same reference numbers are used to identify equivalent elements.
  • the outlet 3 of said sealing 2 element is not attached to the closing 1 element, which is optional.
  • the outlet 3 is made of an elastomer, for example, silicone.
  • the outlet 3 opens automatically when pouring the contents of the package 7 , as in the previous embodiments, and it will close due to the resilient characteristics of the outlet 3 when the contents of the package 7 stop flowing through said outlet 3 .
