Definitions

  • ABSTRACT Foreign Application Priority Data A container comprising an envelope of flexible mate- June 28, 1971 Netherlands 7108899 rial with at least one closure attached thereto.
  • the Y flexible material is substantially tubular and is con- [52] U.S. Cl. "9 150/8, 150/3 stricted in the way of a bag at least at one end by gath- [Sl] Int. Cl. B65d 33/16 ering the material around an associated insert closure.
  • the insert closure is made of material having natural rigidity.
  • This invention relates to a container substantially comprising an envelope of flexible material with closures mounted thereon.
  • the strong flexible container wall material used for these purposes is provided with closures which may comprise a sewing or sealing seam or may be formed in that the flexible container wall material has been glued up along specific closing seams. It is also possible, in particular when no liquids are concerned, to form packs by wrapping up a specific quantity of bulk material together with theflexible material, while tying up the resultant bundle to a packet by wrapping with an appropriate material.
  • Such containers are known in cylindrical, square or even in cushion model form.
  • the filling is performed often through an opening left in a glued, sealed or sewn closing seam, and wherefrom may project a filler trunk. After filling said trunk has to be closed, which may be effected by for instance tying up with an appropriate binding material such as rope or cord.
  • the container wall material For shipping such containers, for instance by means of a hoist, a fork lift truck or such tools, the container wall material should be provided with loops, hooks or eyes or the container should be placed in a frame or on a pallet. Sometimes there are also formed on the flexible container wall material projecting flaps with holes enabling engagement of the container for its handling.
  • the flexible material is substantially tubular and in the manner of a bag is constructed and held by grasping around an appurtenant insert closure of material having a natural rigidity, of which closure the size in cross-section is on at least one closure end at least considerably smaller than the inner periphery of the non-constructed, open covering end, and of which the size in a central area between the two closure ends is at any rate slightly smaller than in the former closure end.
  • the insert closure according to the invention has preferably a substantially conically flaring configuration from its central area to at least one closure end over at least part of the distance to the respective end.
  • a suitable material may be any vegetable, mineral or synthetic material having a specificnatural rigidity such as wood, plastic, metal, etc.
  • the flexible container wall material is now constricted in any suitable way, for instance manually, by wrinkling around the insert closure central area with narrowed size relative to a wider end inserted in the constriction by means of rope, textile ribbon, metal band and like material, so that the container wall material wrinkled through constriction is firmly retained in position.
  • forces which are exerted on the insert closure for loosening same from the constriction will result in that the constricted container wall material will come to lie tightly still against the outer circumferential side face of the insert closure flaring from the narrowest central side area, resulting in that the insert closure comes to be tightly wedged in the constricted flexible container wall material.
  • the container wall material constricted by wrinkling is thereby also reinforced adjacent the constriction by the multiplication of the material as a result of the wrinkling, so that a closure is obtained that is highly resistant to external forces.
  • the flexible container wall material may be constricted or closed on the other end of the container by application of a constrictor or tie and the thus constricted envelope end may be bulged into the interior of the container before the filling has been put in the container. This may be done by turning the still open container inside out.
  • the constrictor By applying the constrictor at some distance from the relevant container end, it is possible to slightly fan out the envelope end reaching beyond the constriction after the turning inside out of the still empty container.
  • the filler material for the container then ensures, through pressing by gravity on the fanned out flexible container material at the covering end, an adequate securing of the constriction material to the inwardly bulged container end.
  • a container having an insert closure according to the invention for closing the one envelope end after filling the container it is also possible for closing the other envelope end, prior to filling the container, to have adjacent the other envelope end, constriction of the flexible container material with a second insert closure of the said type bulged into the interior of the container by turning the envelope inside out through its original outer end.
  • the invented closure is particularly favorable, because owing to the loosening and the release of the constriction at the opened container end, the entire internal transverse section of the container will become available for a rapid, undisturbed filling or emptying.
  • the container when one starts from already tubular flexible container wall material, the container can be closed without application of any technique used in the clothing industry, such as sealing, sewing or glueing;
  • the closure can be effectd rapidly, reliably and in a cheap manner with application of the insert closure;
  • the design can be kept so inexpensive, that for many uses it is economically justified to dispose of the container without any objection once it has been used;
  • the insert closures in particular when their sizes widen on either side gradually from the area with the narrowest transverse section size, are particularly suitable for application thereon of all kinds of auxiliary devices; hooks, eyes, passages, provided for instance with a cock, a valve,.clamping rings etc;
  • the insert closures may also be formed of a plurality of portions to be combined
  • liquid-tight foil bag or tube attached to such an insert closure, which bag or tube is accommodated during the insertion in the hollow space formed by the flexible container wall mate- I rial and comes to abut during the filling with the liquid on the inside against said flexible container wall material so that an inexpensive efficient and reliable liquid container is obtained;
  • FIG. 1 is a cross-section of a container according to the invention with an insert closure sealingly disposed on either side;
  • FIG. 2 is a view side-of a diabolo-shaped insert closure provided with a lifting eye anchored thereon;
  • FIGS. 3 6 show in cross-section various modified embodiments for bottom closures without application of an insert closure for the invented container of flexible material.
  • a container generally indicated by reference numeral 1 substantially comprises a tubular body 2 of a strong, flexible material, and two insert closures 3 and 4 having a diabolo-shaped configuration, while the material of the tubular body 2, by means of binder material, e.g. nylon cord, is pressed at its two open ends against the centrally constricted peripheral faces of the insert closures 3 and 4 at 5 or 6, while constricting said flexible wall material, and is tied up by wrapping.
  • binder material e.g. nylon cord
  • a strong polyethylene fabric provided with a suitable coating, is employed in the embodiment shown.
  • the two diabolo-shaped insert closures 3 and 4 are made of wood. Each closure has two frustoconical segments 3a and 3b or 4a and 4b which slope inwardly from opposite ends of the closure to a juncture 30 or 40 intermediate these ends, giving the closures their diaboloor hourglass-shaped appearance.
  • the lowermost insert closure 3 shown in FIG. 1 is first inserted as inserted, for insert closure 4, in the constricted container wall material, whereafter the tubular body 2 is turned inside out, enabling insert closure 3 to occupy the position shown at the bottom of FIG. 1 with the binder material 5 in the interior of the container space.
  • the insert closure may be slightly resilient at least at its outer periphery through which a still better closure is obtained, particularly in applications involving liquids or very fine granular or powdery bulk material in the container.
  • FIG. 1 In the left half of FIG. 1 is shown as a variant by reference numeral 7 a thin bag or liner of plastic foil material by means of a broken line, which bag has its opening edge adjoining to and around the one mouth of a longitudinal passage extending between the end faces of the insert closure 4.
  • the liner is sealingly attached to the lowermost face of said insert closure, for instance by glueing.
  • a valve In the longitudinal passage having the reference numeral 8 a valve is schematically drawn at 9. Filling and emptying of the plastic bag 7 is possible through passage 8 with valve 9.
  • the liner comes to abut internally against the tubular body of flexible material and at the bottom against the face of the lower insert closure 3 turned towards the interior of container 1, said face being the topmost in FIG. 1.
  • FIG. 2 shows at a considerably enlarged scale an insert closure 10 having also a substantially diabolo or hour-glasslike configuration, but in this case not of symmetrical shape as is the insert closure 3 of FIG. 1.
  • the upper or outer frustoconical segment 10a of the closure member is shorter than the lower or inner frustoconical segment 10b, and the base of the upper segment is narrower than that of the lower one.
  • the two frustoconical segments 10a and 10b of closure member 10 slope gradually from opposite ends of the closure member to a narrower juncture 10c intermediate these ends.
  • a lifting eye 11 projects on the top side, which eye is attached at the end of a rod 12, which extends in longitudinal direction in the figure from the top to the bottom through the insert closure and is secured by means of nuts 13 and 14.
  • FIGS. 1 and 2 are shown insert closures which conically widen from the insert closure area towards the two ends, it is also possible to successfully apply an insert closure which only widens towards the end extending into the container, both at the bottom container end where the closure member is oriented with the wide end outside so that it will be correctly positioned when the container is turned inside out and at the upper of lifting end of the container.
  • olefin fabrics whether or not provided with a coating and other fabrics made from natural or synthetic materials, whether or not coated with natural rubber, PVC, synthetic rubber or such materials, as well as reinforced or non-reinforced paper laminates, foils and like materials.
  • binder means such as cable, rope, cord or the like.
  • FIGS. 3 6 the envelope or tubular container body wherein in all said figures only the bottom end is shown is also indicated by reference numeral 2.
  • envelope 2 at the bottom, is constricted or closed by means of a constrictor (or tie or retainer) of rope or the like binder material.
  • Said constrictor 15 is tighetened around the originally outer side of the envelope end, after which the envelope 2 is turned inside out.
  • the reference numeral 2' the end of the flexible wall material of the container is indicated in a condition which is fan shaped relative to the constriction 15.
  • FIG. 4 a he'm is formed by means of the stitching seam 16 to form an internal space loop at which reference numeral 17 is placed in said figure.
  • the folding back to hem of the pertinent envelope end was originally effected in outer direction, and after application of stitching seam 16 the envelope was turned inside out.
  • 18 is shown in this figure 4 a rigid ring which is accommodated in the hem.
  • 19 is shown a piece of flexible material covering the opening 20 inside the ring 18 with a broad overlapping edge 19'. Flap 19 was of the same quality and type of material employed for the envelope 2. Through the pressure of the filling material 21 in the container on the overlapping edge 19 said covering piece 19 of flexible material is well maintained over the opening 20.
  • a circular member is provided in a circular hem of the flexible container material at a relatively large distance from one envelope end to partly constrict the container wall.
  • the circular member is considerably narrower than the original envelope, and the flexible container material, extending from the hem to the respective envelope end, extends in the form of a trunk through the opening formed within the constriction.
  • the end of the envelope is closed by constriction of said turnk.
  • the hem is preferably formed on the originally outer side of the envelope after which the envelope is turned inside out.
  • the formed trunk can, at least partly, be pressed inwardly prior to, during, or after filling and can optionally be retrieved for emptying the container.
  • FIG. 5 A container closure as just described is shown in FIG. 5.
  • a stitched seam disposed at 26 forms a hem with hem space or loop 27 at a considerable distance from the pertinent envelope end.
  • a circular piece of binding such as a piece of rope or cord material going through the hem space 27. With the binding material the original size is formed of the envelope 2 adjacent the hem is so narrowed that an opening 30 of considerably smaller size.

  • a trunk as shown in FIG. 5 with two rigid rings of different diameters at the envelope end provided with the insert closure.
  • the constriction is such that the flexible container material extends inwardly into the interior of the container at a relatively large distance from one envelope end through an annular means which is narrow with respect to the original envelope size, and a relatively wider annular member is placed mainly concentrically with the above annular means in the thus inwardly bulged flexible container material, while fanning out the' flexible container material adjoining said annular member.
  • the flexible container material forms a trunk towards the respective envelope end, the trunk extending outwardly from the interior of the container through the above annular means and being constricted or closed adjacent said envelope end.
  • the first annular means a non-rigid ring. It is not strictly necessary either in that case to form a trunk: by applying the rings slightly closer to the relevant envelope end, the opening formed inside the narrowest annular means can be covered in a manner similar to that described in the above for the constriction with a hem by means of a flexible piece of material placed inside the container over the two annular means.
  • FIG. 6 shows the embodiment just described; i.e., one without a hem formed by a stitching seam.
  • two rings 37 and 38 of different diameter the lower envelope end is first inserted through the opening 40 of the narrowest ring 37 and pushed up for some distance on the relevant envelope end. After this the envelope is turned inside out so that the envelope end inserted through the opening 40 extends inwardly into the formed container. In this end is inserted the wider ring 38 with the fanning out at 2" of the flexible material bounding the ring 37, after which finally the envelope end is extracted as a trunk 39 through the opening 40, which trunk is constricted by means of constrictor or tie 41, after which as shown in FIG. 6, the trunk is again pushed partly through the opening 40 into the interior of the container.
