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.
Claims19
A chain of sachets comprising a plurality of individual triangular closed flexible sachets bonded together at either one of an extremity of each individual sachet or along a welding line,
- each individual triangular closed flexible sachet comprising:
- an interior space enclosed by one sheet of flexible blank material, the sheet of flexible blank material being welded along only two sides of the triangular closed flexible sachet to define the interior space.
A method of manufacturing a chain of triangular closed flexible sachet holding a substance comprising:
- folding upon itself a flexible sheet to form a triangular interior space;
- filling the triangular interior space with the substance;
- sealing the at least one folded sheet along a plurality of welding lines so as to capture the substance in the interior space;
- and
- repeating the steps above one or more times.
A method of manufacturing a chain of triangular closed flexible sachet holding a substance, comprising:
- rolling a blank sheet of flexible material around itself or around a tube until the margin of the blank is united with the blank itself enclosing a cylindrical volume and creating an overlap of the blank with itself along the margin;
- joining the two layers of the blank at the overlap by sealing to create a tubular structure;
- dispensing the substance into the tubular structure;
- and
- flattening the tubular structure and joining the already formed sealing to the opposite surface of the flattened tube creating a sealing of three layers enclosing triangular interior spaces enclosing said substance.
A method of storage of a chain of closed flexible sachets, comprising:
- folding upon itself in circular motion the chain of triangular closed flexible sachets;
- and
- compacting the folded chain of sachets into a polygonal shape.
A method of displaying a chain of triangular closed flexible sachets, comprising:
- unfolding a chain of flexible closed sachets comprising a plurality of triangle shaped individual sachets;
- and
- hanging the chain of sachets to be displayed.
A hanging device for storing and/or displaying a chain of sachets comprising a plurality of individual triangular closed flexible sachets bonded together at either one of an extremity of each individual sachet or along a welding line, each individual triangular closed flexible sachet comprising:
- an interior space enclosed by one sheet of flexible blank material, the sheet of flexible blank material being welded along only two sides of the triangular closed flexible sachet to define the interior space, the hanging device comprising two upwardly facing sides at a right angle relative to each other in the vertical plane, and a member for fixing the hanging device to a solid structure.
