Definitions
- the present invention relates to a flattened flexible container or intermediate bulk container made ready for being filled with bulk material, and it comprises an outer container of strong load-carrying material and an inner liner of impervious sheet material, e.g. of thermoplastic or paper.
- the invention also comprises a method for manufacturing such containers and means for manufacturing the container.
- 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.
- the object of the present invention was to arrive at a flexible container which when inflated or filled will have a liner with the same form as the outer container and where the liner everywhere lies closely against corresponding points of the outer container, at least that part of the container which shall be filled with bulk material, without using fastening means as tape etc., and that crumpling of the container is avoided.
- a further object was to arrive at an apparatus and a rational way 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.
- a flexible container according to 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 liner to the outer container.
- Containers according to the invention can also be obtained in several other ways than the above one, and some of these will be described in the following text.
- 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 wall b (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.
- a product according to the invention can be made by first placing a liner (2) in a completed outer container (1) which can he 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 product according to the invention can also be made in other ways than the one described above.
- the essential feature of the manufacture is that the liner is placed in the outer container and that the folding is carried out such that both containers are folded in the same way such that the liner everywhere lies against the outer container. This can for instance be obtained by inflating the containers or pressing them out crosswise before both containers are folded.
- the present invention has given a product 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, 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.
