Abstract
A pouch (10) for holding in particular a portion of tobacco substantially comprises front wall (13) and rear wall (14). A filling opening (19) is formed on the upper side between front wall (13) and rear wall (14). Formed underneath the same is a further opening, specifically a removal opening (20) defined by a perforation line (23). Positioned in the region of the same is a closure means which can be used repeatedly, specifically a ziplock.
Claims19
A pouch made of film or the like for bulk goods or fibrous material, in particular for a portion of tobacco (11) as pack content, comprising front wall (13) and rear wall (14), which bound an (upper) opening and are connected to each other laterally and in the region of a base or base edge (12) opposite the opening before the pack content is put in, characterized by at least two independent openings arranged adjacent to each other, of which a filling opening (19) serves (only) for the pouch content to be put in and the other opening, namely removal opening (20, serves (only) for the removal of the pouch content.
A method for producing pouches (10) comprising front wall (13) and rear wall (14) and, if appropriate, a fold-over flap (17) connected to the rear wall (14), in order to hold portions of tobacco (11) as pouch content, the pouches (10) being produced from a continuous film web or material web (40) by forming the front wall (13) by folding over an edge strip of the material web (40) by means of transversely oriented dividing cuts, with the simultaneous production of lateral seams (15, 16) for connecting front wall (13) and rear wall (14), characterized by the following features:
- a) at an edge of the material web (40) facing the front wall (13) to be produced, during the transport of the material web (40), weakening lines running successively in the longitudinal direction of the material web (40), in particular perforation lines (23, 25), are made in the material web (40),
- b) then, in the region of the weakening lines, sections of closure means that act repeatedly are applied to the upwardly oriented inner side in the region of the front wall (13) to be produced, specifically in particular sections of a ziplock (28) consisting of profiled strips (29, 30),
- c) the sections of the ziplock (28) are then connected to the material web (40), in particular by means of thermal sealing, covering the perforation line (23, 25),
- d) the edge strip of the material web (40) is then folded over in order to form the front walls (13) of the pouch (10),
- e) after that, the transversely oriented lateral seams (15, 16) are made outside the sections of the ziplock (28), and the pouches (10) are produced by means of a transversely oriented dividing cut,
- f) the portion of tobacco (11) is then introduced into the pouch (10),
- g) finally, the closure seam (22) is made in the region of the filling opening (19) and the ziplock (28) is connected to the rear wall (14).
An apparatus for producing pouches (10) from thin packaging material, in particular from sealable film, which can be supplied as a material web (40), sections of a ziplock (28) being positioned at an edge of the material web (40) at a distance from one another and being connected to the material web (40) by means of thermal sealing, characterized in that the material web (40) with the sections of the ziplock (28) can preferably be led continuously through a (first) sealing station having a sealing assembly (45), which has a rotating sealing roll (54) having sealing strips (55, 56, 57) fitted to the circumference and which, as a result of the wrap of the sealing roll (54) during a phase of the transport of the material web (40), bear on the latter in order to form sealing seams, specifically connecting seams (35, 36) and a preliminary seam (41).
