Definitions

  • the present invention relates to a sealed closure device for a box and a box provided with this closure device.
  • a device for sealing a box of the type comprising a sheet for closing an opening of the box, made of a composite material comprising a sheet of metal coated with a layer of heat-sealable polymer on the box, fixed by a weld line on the edge of the opening.
  • This type of device guarantees not only a tight closure of the box but also an inviolability of this box, which is particularly sought after when the box contains food products.
  • the box is opened by puncturing the cover sheet or by removing it by tearing off.
  • the puncture or tearing of the sealing sheet leaves pieces of this sheet hanging on the edge of the opening of the box, these pieces being unsightly, which can hinder access to the inside of the box or else injure the user.
  • the object of the invention is to allow complete removal of the closure sheet so as not to leave any piece of this sheet hanging on the edge of the opening of the box.
  • the subject of the invention is a device for sealing a box of the aforementioned type tightly, characterized in that the edge of the closure sheet projects beyond the weld line and includes a reinforcement thickness of this leaf.
  • the invention also relates to a box comprising a sealed closure device as defined above.
  • this box is made of sheet metal.
  • FIG. 1 shows a box intended for example to contain food products in particulate form, designated by the general reference 10.
  • this box is made of metal sheet and comprises a body 12 delimited by a side wall 14, of octagonal outline, extending between a bottom (not shown in the figures) and an opening 16 forming the top of the body 12 .
  • the opening 16 is intended to be closed, firstly by a cover 18 intended to be removably fitted onto the top of the body 12, and secondly by a sealed closure device 20 according to the invention.
  • this closure device 20 comprises a closure sheet 22 delimited by an octagonal contour, of dimensions substantially greater than those of the opening 16 so as to protrude all around this opening 16 .
  • the closure sheet 22 is made of a composite material comprising an aluminum sheet 24 coated with a layer of heat-sealable polyethylene 26 on the box 10.
  • the sealing sheet 22 is fixed by a weld line 28 to the edge of the opening 16 delimited by a rolled edge 30 extending the upper end of the side wall 14 towards the inside of the body 12 of the box.
  • the weld line 28 is produced by known means causing the polyethylene to melt and its adhesion to the edge 30.
  • the edge of the closure sheet 22 protrudes beyond the weld line 28 and includes an additional thickness 32 for reinforcing this sheet 22.
  • the additional thickness 32 is formed by a fold of the edge of the closure sheet 22 so that the polyethylene layer extends inside the fold 32 and that the aluminum sheet extends to the outside of this fold 32. In this way, the contiguous parts of the fold 32 are held against one another by melting the polyethylene when the sheet 22 is welded to the rolled edge 30.
  • the fold 32 can be replaced by a strip of composite material, similar to the material of the closure sheet 22, attached by welding to the edge of this closure sheet 22.
  • closure sheet 22 also includes a tear-off tab 34 extending the edge of this sheet 22.
  • closure sheet 22 The removal of the closure sheet 22 is therefore done quite simply, after opening the cover 18, by lifting the tongue 34 so as to move it away from the box body, then by pulling on this tongue 34 so as to tear off the blanking sheet 22.
  • the reinforcing ply 32 extending at the periphery of the closure sheet 22, makes it possible to avoid tearing of this sheet 22 when a tear-off force is exerted at the weld line 28.
  • the box 10 can be made of plastic, a composite material comprising cardboard and aluminum, or any other material on which the closure sheet can be heat sealed.
  • closure sheet can be made of a composite material comprising a metal sheet, other than aluminum, coated with a polymer, other than polyethylene, heat-sealable on the box.
  • the invention has many advantages.
  • the waterproof closure device according to the invention makes it possible to completely tear off the sealing sheet, when opening the box, without leaving pieces hanging on the edge of the opening of this box.
  • closure sheet is very resistant to tearing during tearing while having a relatively reduced thickness.
