Abstract

The present invention relates to a fluid tight tape for a perforable package or packet, which perforable package or packet is particularly suitable for containing under vacuum foodstuff to be thermally treated, comprising:

• • a laminar body (2), made of elastically deformable material and resistant to relatively high temperatures, designed to be applied to the perforable package or packet suitable for containing the foodstuff to be thermally treated;
  • a glue means (4) provided at one face of the laminar body (2) facing, in use, the package or packet, the glue means (4) being designed to make the laminar body (2) tightly adhere to the package or packet,
    the laminar body (2) having a bare area (5), lacking glue, at which a through opening (6) is obtained. The fluid tight tape comprises an elastic insert member (7) tightly housable in and anchorable to the through opening (6) of the laminar body (2), the elastic insert member (7) being designed to remain, in use, adjacent to or in contact with the package or packet with no interposition of the glue means (4).

Claims

1. A fluid tight tape comprising:

a laminar body, made of elastically deformable and heat-resistant material; and

a glue provided on one face of said laminar body,

said laminar body having a bare area, lacking glue, on said one face of said laminar body, in which a through opening is made and

wherein

said laminar body has an elastic insert member which may be perforated and is tightly housable in and anchorable to said through opening of said laminar body, said elastic insert member not being in contact with said glue, and

said insert member comprises a stem having one end configured as an enlarged head designed to be abutted against said bare area around the through opening, the enlarged head having a flat surface which is designed to be abutted against said bare area and having a curved surface opposite said flat surface.

2. The fluid tight tape according to claim 1, wherein said insert member has a stem with a rib or a relief or with an annular channel or groove for the snap engagement with an annular channel or with a rib or a relief provided in the through opening respectively.

3. The fluid tight tape according to claim 1, wherein said insert member has a stem provided with a succession of ribs and grooves.

4. A fluid tight tape comprising:

a laminar body, made of elastically deformable and heat-resistant material; and

a glue provided on one face of said laminar body,

said laminar body having a bare area, lacking glue, on said one face of said laminar body, in which a through opening is made and wherein

said laminar body has an elastic insert member which may be perforated and is tightly housable in and anchorable to said through opening of said laminar body, said elastic insert member filling said through opening of said laminar body and said elastic insert member comprising a stem having one end configured as an enlarged head having a flat surface designed to be abutted against said bare area around said through opening and having a curved surface opposite said flat surface.
