Definitions

  • the invention relates to a valve device in a bag, which has two welded sheets with an opening, which extends from the edge of the bag into the inside of the bag along a channel defined by two weld seams, the valve arrangement having two valve flaps which are fastened on the respective channel inside to form pockets between the outer leaves and the valve flaps, the pockets opening towards the inside of the bag are.
  • valve function in such bags is evident when the liquid filled through the opening flows back towards the opening after the bag has been turned over.
  • the liquid is directed into the pockets and the valve flaps are compressed over the opening so that the valve acts as a check valve or as a one-way valve.
  • valve flaps are pressed outwards against the leaves and adhere to them by means of static electricity and / or by the adhesion which, when the surfaces are wet, acts between the compressed leaves.
  • the liquid flowing from the inside of the bag will not penetrate the fully or partially closed pockets in sufficient quantities, and consequently the result at best is that a large part of the liquid will spill before the valve flaps may close the opening, and at the worst In this case, the valve flaps will not close the opening at all until all the liquid has drained out.
  • valve flaps Even if the valve flaps close the opening before a substantial amount of the liquid has flowed through the opening, problems can arise later during the handling of the bags, because the valve flaps, as soon as there is no liquid in the pockets between the leaves and the valve flaps, tend to follow the outer leaves .. This closes the closing action and will usually be lost when the liquid flows back towards the opening, because the inside of the outer leaves and the upper sides of the valve flaps stick together due to the remaining moisture.
  • the object of the invention is to provide a further development of the above-mentioned known valve arrangement which is absolutely reliable in use, without the need for complicated valve installations or the like which cause additional costs.
  • valve device which is characterized in that the outer leaves and the valve flaps are welded together to form a narrow tubular inlet within the channel at two longitudinal weld seams which run from the transverse weld seam in the direction of the interior of the bag.
  • the outer leaves are loosely above the tubular inner inlet when filled, so that the amount of air that will always be present, even in a flat bag, will penetrate into the narrow pockets on the sides of the tubular inlet and keep them expanded so that the backflowing liquid certainly flows into the open pockets and from there continues through the valve flaps around the inner inlet and compresses the flaps.
  • the longitudinal weld seams end at a short distance in front of the lower edge of the valve flaps.
  • the inlet has the shape of an hourglass and the valve flaps are fastened in the narrowed area of the hourglass on the associated inside of the channel.
  • the channel cross-section narrows below the mouth of the narrow tubular inlet at transverse weld seams from the edge of the hourglass-shaped channel to the center line of the channel.
  • This embodiment has a well-defined weakening point between the bag interior and the protruding lower area of the hourglass-shaped inlet channel. This is particularly advantageous when using the bag for freezing liquid foodstuffs, because then there is no longer any risk that the foodstuffs will be ver from leaf particles that are frozen in the lower region of the inlet channel get dirty. The lower portion of the inlet channel is torn off the bag at the periphery of the narrowed area and discarded.
  • the narrowed area is substantially the same width as the narrow tubular inlet.
  • the liquid flows through the inner inlet and the restricted area so slowly that the air enclosed in the bag interior can penetrate into the pockets on the circumference of the inlet interior.
  • valve flaps are formed by folding in the outer leaves.
  • This valve is very easy to manufacture and can be produced by simply welding two substantially rectangularly cut sheets.
  • the bag according to FIG. 1 has two sheet foils which are partially welded to one another, the weld seams being indicated by the obliquely hatched areas.
  • At the top of the bag there is essentially one hourglass-shaped inlet channel 7, the lower end of which opens into a plurality of interconnected shaped cavities.
  • the valve device according to the invention is arranged on the hourglass-shaped inlet channel 7.
  • the channel 7 is thus defined by longitudinal weld seams 5, 6, which extend from the edge of the bag to the interior 4 of the bag.
  • valve flaps 8, 9 are arranged in the lower region of the inlet channel 7 and a folded-over section of the foils is welded to the outer foils 1, 2 in the region 10. This creates pockets 11, 12 between the outer foils and the valve flaps, these pockets being opened in the direction of the bag interior 4.
  • the inlet 3 leads into the interior 4 of the bag.
  • Figure 3 shows the bag filled with liquid.
  • the weld seams 13, 14 (see also FIG. 1) which extend in the longitudinal direction from the channel 7 form an inner inlet 15 within the channel 7.
  • the pockets are formed on the inlet sides between the weld seams 13, 14 and the corresponding weld seams 5 and 6, respectively.
  • valve flaps 8 and 9 form a continuation of the tubular inner inlet 15 at their lower edge, the valve flaps 8 and 9 being contracted on both sides of the inner inlet 15.
  • the outer leaves 1 and 2 are arranged loosely above the inlet 15 to form openings (represented by the dashed area). There, the liquid can penetrate unhindered as it flows back up through the tubular inlet 15, which is thereby compressed and closed.
