Definitions

  • the invention relates to a Ventiisack according to the preamble of claim 1, a method for producing a valve sack according to the preamble of claim 11 and a system for producing a valve sack according to the preamble of claim 16.
  • Valve bags are those bags that are completely finished prior to filling and later on are filled with the valve, so that no subsequent closing of the bag is necessary. Such bags can be filled particularly quickly and efficiently in filling machines. Filling goods are often powdery goods such as building materials, especially cement.
  • the present invention relates to such valve sacks described above comprising a first and a second wall which are interconnected by side edges or gussets.
  • Floors are provided at the ends, via which the two walls are also connected to each other.
  • the walls define the interior of the bag, along with the bottoms and possibly along with the gussets.
  • the valve is arranged; This floor can therefore be referred to as a valve floor.
  • the other floor is completely closed, ie, the inside of the bag can not be reached from the outside via this floor.
  • This floor can also be called a valveless floor.
  • the end of the bag comprising the valve bottom may simply be referred to as the "top” or “top”.
  • the second end is therefore “below” or it is the “lower end”.
  • vents are provided in the first and / or in the second wall.
  • a challenge is always » to provide a high venting performance, but also to design the bag in such a way that, on the one hand, no filling material can escape through the vent openings and, on the other hand, moisture can not penetrate into the interior of the bag. After escaping filling leads to a product loss or even, depending on the nature of the medium to Gesundheti 'ssc ädigungen of people, for example, carry such filled bags. In the interior of the bag entering moisture can make unusable in the long run, the contents.
  • the object of the present invention is therefore to propose a generic bag and a manufacturing method for such a bag, which offers improved Gregutschhalt despite the large required venting performance. In addition, improved moisture protection is desirable.
  • At least one channel is provided on the outside of at least one wall. which covers the vents and which is formed by at least two parallel attachment strips and a cover strip, the cover strip also includes vents and wherein the shortest path between the parallel attachment strips along the Uberdeckyngsstsammlungs is longer than the shortest path along the at least one wall. It is thus formed by a Oberdeckungsstsammlung, which is arranged on the outside of at least one wall, and at least two fastening strips, with which the cover strip is fixed to the wall, a channel which covers the ventilation openings.
  • the shortest path between the parallel fastening strips, ie the path across the fastening strips, along the covering strip is longer than the shortest path along the at least one wall.
  • the overlap strip is labile between the attachment strips when the area of the wall between the attachment strips is flat.
  • the channel can form a cavity. It is advantageous that in this cavity, the air can flow through the vent holes, even if bulging during the Behelivorgang the wall to the outside.
  • the cavity or the channel can absorb and store a great deal of air from the interior in a short time and can release it over a longer period of time, preferably to the environment.
  • the overlay strip and / or the parallel attachment strips are made of stretchable material.
  • a labile overlap strip can be a cover strip with a stretchable Material kicking.
  • at least one of the attachment strips may comprise a stretchable material.
  • An extensible material may be elastic or deformable, for example stretchable, as is known, for example, in the case of films, which can be elongated under the action of force. Due to the air emerging from the interior of the bag through the ventilation openings, the cover strip and / or the fastening strips can now be stretched so that the channel can provide an increased volume compared to the initial state. This again ensures that in a short time a large volume of air can be removed from the bag interior.
  • the top cover strip in order to be able to store the still unfilled bag flat, may comprise a U-shaped fold on at least one of the attachment strips, i. H. be folded so that its folded outside with the mounting strip is attached to the wall. This ensures that the fastening strip can bulge in a simple manner, without his material is overused.
  • the overlay strip may comprise a z-fold.
  • the valve bag according to the invention may comprise paper, but also a material of one or more plastics.
  • Plastics may be a film web, but also a fabric made of plastic tapes, in particular of such plastic tapes comprising a stretched polyolefin.
  • a plastic according to the invention may also be a nonwoven material.
  • the aforementioned materials can also be combined.
  • one wall of the bag may comprise two layers, one layer of paper and the other layer of plastic.
  • the aforementioned materials may also be laminated, laminated or otherwise coated.
  • the overlay strip can consist of the same material or the same materials as the bag, but also of at least one of them different materials.
  • the overlay strip may be a separate strip, preferably in the longitudinal direction of the bag.
  • the overlay strip extends over the entire longitudinal extent of the bag.
  • the attachment strips may be adhesive strips such as cold glue, hot melt or dispersion, or extrusion strips.
  • extrusion strips or, in other words, extrusion longitudinal seams offer advantages since they are inexpensive.
  • a fastening strip can also be a joining strip, in which the wall and the covering strip are joined together by welding or sealing, in particular by ultrasonic, infrared or hot air welding or sealing.
  • the overlay strip may be a separate workpiece.
  • the overlay strip may be an area of at least one wall that covers another area of the wall.
  • Cover area can be made by a tube formation from a
  • the walls and the cover strips are integrally formed.
  • the overlapping part then only needs to be fastened with two or more attachment strips running parallel but spaced transversely to form said channel.
  • the bag according to the invention has a venting capacity of at least 5 m 3 / h, in particular of at least 10 m 3 / h.
  • This venting performance refers to air, but does not deviate greatly from other gases.
  • the shortest path between the parallel attachment strips along the overlay strip is at least 3% longer than the shortest path along the at least one wall. In this case, sufficient storage is provided for the air escaping from the interior of the bag, at the same time keeping the tipping of the cover strip small. This helps avoid damage especially the Cover strip. Furthermore, it can be provided that the invention is provided that the shortest path between the parallel attachment strips along the overlay strip is at most 20%, in particular at most 10% longer than the shortest path along the at least one wall. In an advantageous embodiment of the invention, a layer of a filter material is provided within the channel. This filter material serves as another filter to reduce once again the delivery of contents to the environment.
  • the filter material has small pores, which offer Lucas miciässtechnik, Greinpismen and dusts but obstruct the way.
  • the filter material is attached to the overlay strip, the filter material preferably covering all the vent openings of the overlay strip, which will be described in more detail below.
  • the possible ways of attaching the filter material to the overlay strip may be the same as those for attaching the overlap strip to the wall.
  • At least one fastening strip for the filter material can coincide with a fastening strip for the covering strip. It is preferred, however, that the fastening strip for the filter material is spaced from the fastening strip for the cover strip, since then makes the production of the bag easier.
  • the filter material may include papers or plastics, which in particular each be present as a nonwoven.
  • At least one layer of a filter material is provided in the bag interior, wherein the filter material also covers the ventilation openings here.
  • the filter material may be similar to the filter material as described in connection with the overlay strip. The types of attachment can be the same. Alternatively, the filter material may replace the vents.
  • the at least one wall may comprise at least one region-wise recess, which is then completely covered by the filter material.
  • the air permeability of the vent holes is at least one wall is greater than the air permeability of the cover strip in the, in principle "in connection with all the described above and also below features and characteristics of the invention, it is also possible that the overlapping strip free of vents and that instead of the mounting strips have interruptions through which the air can flow. But it is also a combination of both aforementioned ventilation options conceivable. If the covering strip has a lower air-permeable chain, in particular a slow escape of the air into the environment is possible, so that again the escape of filling material is reduced. In this context, an icro- or nano-perforation of the overlapping strip is advantageous.
  • microperforations for example with a density of 10 to 30, in particular 13, vents per square centimeter (cm 3 ), and nanoperforations, for example with a density of 50 to 100, in particular 64, vents per Ouad centimeter (cm 3 ), from each other can often be differ.
  • the perforations may be formed with substantially conical needles or with substantially cylindrical needles.
  • the vents are preferably small enough so that no moisture can enter from outside into the bag or into the channel. This is usually the case when the vents are smaller than 0.8 mm in diameter.
  • the vent openings of the at least one wall in the longitudinal direction of the bag are spaced from the vent openings of the overlapping strip.
  • This distance is preferably at least one third of the bag height. It is advantageous that the air from the bag interior must travel a long way to get into the environment. This leads to moisture that could penetrate into the channel, or at least only very slowly reaches the inside of the bag.
  • the vents may be formed as holes or as slots. Holes are often created by needles, whereas slots are often produced by knives.
  • the slots are provided in the at least one wall, in order to provide a large venting performance here. The venting performance can be further increased if at least two slots are at an angle to each other, especially in a right-hand angle! (90 °).

  • the vent openings in the at least one wall is at most half a bag length, in particular at most one third of the bag length, more preferably a quarter of the bag length spaced from the valve bottom.
  • a bag length "in particular at most a third of the bag length and more preferably a quarter of the bag length from the valveless floor maximum is advantageous. In this way, a good protection against penetrating moisture is achieved, because any penetrating moisture has to travel a long way to the inside of the bag.
  • the surface of the bag provided with vents is at most 15% of the total surface area of the bag.
  • valve bottom comprises two bottom flaps, wherein the first bottom flap comprises parts of the overlapping strip, the second bottom flap, as seen from the outside, at least partially covering the first bottom flap. This will prevent that passes through the bottom flap moisture in the channel and from here on a short path through the vents in the at least one wall in the bag interior. The moisture protection is thus increased. It is also advantageous if the valveless bottom comprises two bottom flaps, wherein the first bottom cover parts of the overlay strip comprises » seen from outside the bag, the first bottom flap, the second bottom flap at least partially covered. This can be prevented that moisture that penetrates through the vents in the channel, passes through the bottom flap in a short way in the bag interior. The moisture protection is thus increased.
  • the moisture protection can be further improved if at least one floor is covered with a ground cover sheet from the outside and / or with an inner latch from the bag interior.
