Abstract: The cellulose-based packaging includes a tubular body obtained by welding or bonding a sheet, including at least one longitudinal weld linking the ends of said sheet, at least one internal welding strip situated inside the packaging to form the longitudinal weld, the internal strip including a sealing material which becomes liquid during the welding of the ends and fills cavities formed at the ends of the internal strip so that the packaging is leak-proof once welded.

Abstract: The invention relates to a tube part, for example a tube head or a cap, the part comprising a structural portion and at least one functional portion, the structural portion having a high cellulose content and the functional portion having a reduced cellulose content. The invention also relates to a package comprising at least one such part and a method for manufacturing the part for the package, and the package.

Abstract: The invention relates to a tube head (1, 2) intended to form a packaging, the head (3, 6) being intended to be welded to a tubular skirt (8, 9) in order to form the said packaging, and the tube head (1 2) being thermoformed from a sheet (20, 21). The invention also relates to a method for manufacturing such a tube head (1, 2) and a tube with said head (3, 6).

Abstract: The invention is directed to a cap (10) for receptacles (20) such as e.g. glass jars, comprising a cap base body (11) with a fixing means (13) for enabling the cap (10) to be removably attached on the receptacles (20), a backing layer (2) made from a deformable material, and a sealable, preferably heat-sealable membrane (3) not being glued to the backing layer (2), wherein both the backing layer (2) and the membrane (3) are retained inside the cap (10) via a retention portion (18) extending from an inner side wall (14) of the cap (10). The invention is further directed to a receptacle (20) having said cap (10) for closing it, and is also directed to a method for providing the cap (10) with a sealing element (1) and for providing said cap (10) onto the receptacle (20).

Abstract: The present invention relates to a sealable element (1) for sealing the rim (21) of receptacles (20), the element (1) comprising at least a backing layer (2) made from a deformable material, and a sealable membrane (3) detachably connected to the backing layer (2), wherein the membrane (3) comprises an additional or integral opening means (4), wherein at least the membrane (3) has a contour with a radius varying between a lower radius value (L) and an upper radius value (U), wherein the ratio between the lower radius value (L) and the upper radius value (U) is defined by the equation 0.9?L/u?0.99, preferably 0.95?L/u?0.97. The invention further relates to a cap (10) comprising said sealable element (1) and to a receptacle (20) comprising said cap (10) being removably attached onto an opening (O).

Abstract: The present invention relates to a sachet (1) having a triangular shape and comprising an interior space (6) enclosed by one sheet of flexible blank material, the sheet being folded upon itself to form a front layer (2) and a rear layer (3) of the sachet (1). The front layer (2) and the rear layer (3) are joined by sealing (4) located along two edges (5) of the sachet (1) to define the interior space (6). The sachet (1) comprises a means (7) for starting opening of the sachet (1) as well as a tear strip (11) arranged between the front layer (2) and the rear layer (3) of the sachet (1) in proximity to and running at least partially along the sealing (4) at one of the two edges (5) joined by sealing (4). The shape of the sachet (1) and the arrangement of the tear strip (11) are so that the sachet (1) obtains a cone-like shape after opening so that it is easy both to hold by hand and to reach into to take out content from the sachet (1).

Abstract: The invention is directed to a cap (10) for receptacles (20) such as e.g. glass jars, comprising a cap base body (11) with a fixing means (13) for enabling the cap (10) to be removably attached on the receptacles (20), a backing layer (2) made from a deformable material, and a sealable, preferably heat-sealable membrane (3) not being glued to the backing layer (2), wherein both the backing layer (2) and the membrane (3) are retained inside the cap (10) via a retention portion (18) extending from an inner side wall (14) of the cap (10). The invention is further directed to a receptacle (20) having said cap (10) for closing it, and is also directed to a method for providing the cap (10) with a sealing element (1) and for providing said cap (10) onto the receptacle (20).

Abstract: The present invention relates to a sealable element (1) for sealing the rim (21) of receptacles (20), the element (1) comprising at least a backing layer (2) made from a deformable material, and a sealable membrane (3) detachably connected to the backing layer (2), wherein the membrane (3) comprises an additional or integral opening means (4), wherein at least the membrane (3) has a contour with a radius varying between a lower radiusvalue (L) and an upper radiusvalue (U), wherein the ratio between the lower radiusvalue (L) and the upper radiusvalue (U) is defined by the equation 0.9?L/u?0.99, preferably 0.95?L/u?0.97. The invention further relates to a cap (10) comprising said sealable element (1) and to a receptacle (20) comprising said cap (10) being removably attached onto an opening (O).

Abstract: The present invention relates to triangular closed flexible sachets (100), and methods of manufacturing a triangular closed flexible sachet holding a substance comprises folding upon itself at least a single flexible sheet (200) to form a triangular interior space, filling the triangular interior space with the substance, welding the at least single folded sheet along a plurality of welding lines so as to capture the substance in said interior space, and sealing the closed flexible sachet (100). The invention further relates to methods of folding, displaying and/or storing a chain of sachets and a hanging device for a chain of sachets.
