Definitions

  • the present invention relates to a method for manufacture of flattened flexible container or intermediate bulk container according to the generic part of claim 1.
  • Containers of that kind are ready for being filled with bulk material; the liner may consist e.g. of thermoplastic or paper.
  • the invention also comprises means for performing the method for manufacturing such containers.
  • the final centration of the liner in the outer container can take place by its inflation at the filling station, for instance as described in GB Patent No. 1.475.019 (corresponding to Norwegian Patent No. 136.744).
  • the liner will then be pressed against the outer container and be in close formation with it, presupposing that the liner originally is correctly placed and fastened to the outer container. Accordingly, this method presupposes great accuracy during placement of the liner in the outer container.
  • a container consisting of an outer load-carrying container of roundwoven material and a liner of thermoplastic sheet.
  • the sheet is centrally placed and possibly folded during manufacture of the roundwoven base material for the load-carrying container. Cutting of suitable pieces of sheet and web, and closure of one end of the inner and outer container must then be carried out in successive steps.
  • the liner is folded by simple gusset and placed in the middle of the container, which is folded by double gusset. Thereby the folded liner will be placed between the central side fold in the double-folded outer container such that the liner is kept in place in the middle of the outer container during its further manufacture.
  • FR-A-2.509.266 already shows a method of the kind described in the generic part of claim 1.
  • the readily folded container as shown in Fig. 5 or 10 has certain advantages with respect to other known containers in that the liner with its gussets being engaged in the gussets of the outer container will maintain its general orientation in the outer container.
  • the liner and the outer container are separately folded and put into each other. The finer is folded in such a way that it does not contact the inner side of the outer container at all points.
  • the known method therefor is complicated and it does not ensure that the liner is supported by the outer container everywhere when it is filled so that particularly liners of thin material can tear, as is explained in the description.
  • a further object was to arrive at means for performing the above method, i.e. for correct placement of the liner in the outer container at the production site and thereby be able to manufacture a product which is completed as far as possible there.
  • Manufacture of such a product can be carried out in several ways and will to a certain degree depend on whether the outer container is made from flatwoven or roundwoven base material. Primarily the liner and the outer container are folded with gusset lengthwise in the same way such that the liner's gusset is kept in place by the outer container's gusset when the containers are flattened and that corresponding points lie against each other such as stated above.
  • the longitudinal side walls were divided in two and joined together by hinges or the like. Subsequent to inflation the box was pressed together, and during this operation the hinged side walls formed gussets in both the liner and the outer container.
  • the containers were pressed together and could then be drawn out of the box, and optionally they could be folded crosswise of the longitudinal direction and were then ready for transport to the filling site for bulk material.
  • Aflexible container made in accordance with the method of the invention can be connected to a filling apparatus and bulk material can be filled directly into it without prior inflation.
  • bulk material inflation of the container at the filling site can be practical for other reasons than adjustment of the linerto the outer container.
  • the invention is as defined in Claims 1 and 3.
  • FIG 1 a folding apparatus (8) in form of a squarish box or tunnel being open in both ends.
  • the cross-section of the apparatus (8) can of course deviate from the squarish form. It can for instance be rectangular or its walls (7), roof (4) and bottom (5) can be slightly curved.
  • the apparatus (8) can be folded together as its side walls consist of at least two longitudinal parts (7) which are connected to each other and the roof (4) and the bottom (5) by means of pliable joining means (6) which can be hinges, flexible tapes or the like.
  • the method of the invention can be carried out by first placing a liner (2) in a completed outer container (1) which can be equipped with lifting grip (3). Both the liner and the container are then placed in the apparatus (8) and air is blown into the liner (2) and pressing it against the outer container (1) such that it touches the walls (7), roof (4) and bottom (5) of the apparatus (8).
  • the liner or inner container (2) is shown on the figure at a certain distance from the outer container (1), while in practice the two containers will lie closely against each other when they are inflated.
  • FIG 2 there is a side view of the apparatus (8), and one will notice parts of the containers outside the apparatus (8) such that one can get hold of the lifting grip (3).
  • FIG 4 the apparatus (8) is shown after having been pressed completely together, and both containers are folded in the same way.
  • the roof (4) and the bottom (5) of the apparatus (8) are drawn in an artificially large distance from each other.
  • the folds of the liner (2) lie in the corresponding folds of the outer container (1).
  • the width of the gussets will be about 1/4 of the flat laid width of the container, i.e. about 1/8 of the container's circumference.
  • the container manufactured according to the method of invention can also be made in other ways than the one described above.
  • the essential features of the manufacture are defined in Claim 1. This is obtained by inflating the containers before both containers are folded. One can for instance first place the liner in on the outer side of a rack or the like having the same form as the cross-section of the apparatus (8) shown in figure 3. Thereupon the outer container can be placed over the liner and the liner and the apparatus pressed together against the inflation pressure till one gets a folded two-gusset flexible container. In order to use this method the containers must be open in one end.
  • the present invention provides a method for producing a container into which bulk material can be filled without prior inflation at the filling site and without damaging the liner. This leads then to less rejection of containers and totally faster filling of the containers. One also avoids that the liner forms pockets which can not be utilized. Already from the moment the liner and the outer container are folded and until they are filled with bulk material they will be in such relative position which they shall have when filled.
  • the inventors also arrived at a method for manufacturing the product with an apparatus which both by itself is rational and which in addition simplified the whole process from manufacture of the flexible container till it is filled with bulk material and is ready for further transport to storage or application.
