Definitions

  • This invention relates to a packaging container having flexible walls made of plastic film, paper or the like, wherein the weblike material which forms the walls has been provided with seam welds or adhesive seams to form the closed container, which has a filling opening that is adapted to be closed.
  • Such containers are generally known, particularly in the form of bags or the like, and are used to contain and package various substances, such as gases, liquids, so­lids, pastes, granules, foodstuffs and the like.
  • object is essenmerelytially accomplished in that the filling opening of the container contains a valve, which is closed and main­tained in a closed state by the pressure of the material which has been filled into the container.
  • the consumer can repeatedly take the contents of the container through the valve member without a destruction of the con­tainer.
  • the consumer can refill the container with a different material so that the container can be re-used because the filling and tak­ing are effected through the valve without destroying or damaging said valve.
  • the tubular member is arranged at a seam weld or adhesive seam of the container and depends freely into the interior of the container.
  • an upper portion of the tubular member is laterally secured to a side wall of the con­tainer.
  • the tubular member can more easily be folded when the container has been filled, as is contem­plated in accordance with a further feature of the inven­tion.
  • tubular member is joined at a side seam to a seam weld or adhesive seam of the container.
  • tubular mem­ber is constituted by an inturned tubular portion of the material of the walls of the container.
  • manufacture of the con­tainer can be rationalized because the tubular member will be formed as the seams are formed in a properly shaped blank made from the starting material.
  • the tubular member has an ob­lique shape at its free edge, which surrounds the filling opening in the interior of the container. In that case the filling of the container will be facilitated because the tubular member may have such a shape that the filling opening may well be disposed adjacent to one of the walls of the container.
  • tubular member is backfolded on itself when the valve is closed. This will provide an additional safe onlyty against an escape of the packaged substances.
  • the tubular member may be rolled up in spiral shape when the valve is closed.
  • the container may have two or more valves and associated fil­ling openings.
  • the tubular member consists of two strips, which are made of flexible material and are joined to each other at side seams. This will ensure that the valve will be closed even when the packaged substance is only under a low internal pressure.
  • the container may be subdivided in a labyrinth pattern so that a plurality of valves are provided, which become effective one after the other.
  • a packaging container 1 con­sisting in the present case of a plastic bag comprises flexible walls 2, which may be made of plastic, paper or the like.
  • the weblike material which constitutes the walls 2 has been provided with seam welds or adhesive seams 3, 4, 5 to form the closed container 1.
  • a filling opening 6 is provided in the upper seam weld 5.
  • the material to be packaged can be filled into the container through a fil­ling opening 6, which is formed in the upper seam weld 5.
  • Various substances such as gases, liquids, solids, pastes and other substances can be filled into the packaging con­tainer through the filling opening 6.
  • the filling opening of the container 1 contains a valve, which is generally de­signated 7 and which is closed and maintained in a closed state by the pressure which is generated in the interior of the container 1 by the filled-in material.
  • FIGs 2 to 4 In an explanation of the valve 7, reference is first made to Figures 2 to 4, in which the mode of operation of the valve is diagrammatically illustrated.
  • the illustrations in Figures 2 to 4 are sectional views, which are taken substantially on line II-II and in which like parts are designated by like reference characters.
  • the wall thicknesses are exaggerated.
  • the valve 7 consists of a flexible tu­bular member 8, which contains or, more exactly, surrounds the filling opening 6.
  • the tubular member 8 preferably consists of the same ma­terial as the walls 2 of the container 1 although that material may optionally be used in a somewhat stiffer grade.
  • tubular member 8 is joined by seam welds 9 and 10 to the wall material of the container 1.
  • the tubular member 8 has a highly flattened diameter.
  • the tubular member 8 consists of two strips 11, which are joined to each other at side seams 13,14. This will ensure that the valve will more readily assume a closed state.
  • the flexible tubular member 8 is arranged at the upper seam weld 5 of the container 1 and depends freely into the interior 15 of the container1.
  • the tubular member 8 of the valve 7 assumes the shape that is shown in Figure 3 so that the filling opening 6 communicates through the outlet 16 of the tubular member 8 with the interior 15 and the material to be packaged can be filled into the container.
  • the packaged material can be taken when the valve 7 has been opened in that the tubular mem­ber 8 has been forced open and that said member will auto­matically close itself after a part of the contents has been taken so that such container will be self-closing after a taking of contents and when it has been filled and the container can be re-used several times.
  • Such contain­ers may be used, e.g., to package foodstuffs, such as milk and the like, or in the form of large sacks for a packaging of cereal grains and the like.
  • the flexible tubular member 8 is joined at its side seam 13 to a seam weld or adhesive seam of the container 1.
  • the flexible tubular member 8 is arranged as in the embodiment shown in Figures 1 to 4 and the tubular member may have various lengths. In the illustrative embodiment shown in Figure 8 the tubular member 8 extends close to the bottom 19 of the container 1.
  • the edge which surrounds the mouth 16 of the tubular member 8 has preferably a lateral oblique shape 20 so that the container 1 can more easily be fil­led.
  • the embodiment shown in Figure 9 has basically the same design as the embodiment of Figure 7 in that one side seam 14 of the flexible tubular member 8 is joined to the side seam 5 of the container 1.
  • the flexible tubular member 8 is formed in that the material of the walls 2 of the container 1 is closed in tubular shape by inturned portions 21 and is then welded.
  • Such embodiments are particularly preferred because such containers can be made in a simple manner.
  • the container may have two or more valves 7 with the associated filling openings 6.
  • valve 7 is con­stituted by a multiplicity of internal partitions, which are stepped in a labyrinth pattern.
  • the basic concept of the invention includes also containers which do not necessarily have flexible walls provided that they have a valve which auto­matically closes a filling opening under the internal pressure of the packaged material.
