Frame For Clamping A Container And Method For Mixing In A Flexible Container And Container For Clamping

Abstract

A flexible package for storing and transporting bulk goods. Such flexible package can have material-impermeable connections for spreading out sections of the flexible package wall so as to correspond to a predefined shape. One or more docking connections for filling and discharging can be included. The flexible package can have a square bottom and adjacent to the sides thereof triangular stubs as lateral walls. Together, such lateral walls can form an upwardly open pyramid shape. Opposite the bottom, a coupling element can be connected in such a manner that it presents the flexible package so as to be sealable in a standardized manner on open-sided ends of the lateral walls.

DETAILED DESCRIPTION

[0019] An embodiment example of a frame 10 according to the present disclosure is shown in FIGS. 1 to 3. The flexible package is shown in two embodiment variants, however any one of the figures shows just one variant, in FIGS. 4 to 6 separately without a frame.

[0020] The present disclosure is based on the concept of using such a flexible package 20 as a mixing container of a validated mixing process. Since the flexible package 20 cannot stand on its own, not even after filling, in this rigid form, the present disclosure proposes to design engagement locations or surfaces on the flexile package in such a way that it can at least partially be spread out. Insofar, the illustrations might create the impression to a viewer that the package stands unaided in this form. This is however not the case.

[0021] According to the present disclosure, to this end the flexible package 20 is clamped into a frame 10.

[0022] At least some sections of the wall, preferably however the complete wall in a laterally circulating manner and the bottom 24, are spread out in such a way that according to the views, the flexible package 20 adopts planar wall areas. To this end, various flaps may be provided at the bottom, see FIG. 8, although for the sake of clarity FIG. 8 only shows a single one. Preferably, flaps are fixed to the bottom lateral edges so as to be suspended therefrom, which flaps have for example a central hole provided therein. These flaps shown suspended may be hooked onto struts of the frame (not shown).

[0023] Apart from these connections, which do not allow any material to permeate into the inside of the package, for spreading out at least some sections of the wall so as to correspond to a pre-defined form, the package 20 has at least one docking connection for filling and discharging. To this end, a coupling element 22 is shown that in a simple form may simply be a ring. However, such an opening may be provided not only at the top but also at the bottom. It must be possible to vent the package in a controlled manner in order to achieve its desired form. To this end, the package preferably has a valve opening or a pressurized gas connection. Thus, for example, means for metering inert gas is provided. After discharging, the flexible packages according to the present disclosure have to be discarded. In order to provide improved controllability of such waste, a controlled evacuation through the above-mentioned openings can be achieved.

[0024] In order to improve explosion security, according to the present disclosure both the package and the frame are equipped with grounding lugs.

[0025] The shown embodiment example of the package according to the present disclosure has a square bottom 24 and, adjacent to the sides thereof, triangular stubs as lateral walls 26. Together, they form an upwardly open pyramid shape. The present disclosure also includes other shapes, such as spheres or octahedrons, which may be at least partially approximated with respect to their basic shapes by spreading out according to the present disclosure at least partial surfaces of the package.

[0026] Opposite the bottom 24, the flexible package presents, according to the illustrations, a coupling element 22 in a manner so as to seal the flexible package 20 in a standardized manner connected to its opening-sided ends 28 of the lateral walls 26.

[0027] According to preferred embodiments of the package 20, for an outward spreading out of partial surfaces, pockets 25 are provided as longitudinal guides which follow the connection lines between the lateral walls 26, into which pockets rods of the frame may be inserted, preferably when lowering the package into the frame 10. The rods (not shown) are preferably supported in a manner as to be rotatable at the bottom about a strut of the frame. At the top, they have free ends after the opening up, which are latched into the coupling element.

[0028] However, the frame can also be forced into a certain shape by just using clamping surfaces of the frame.

[0029] Accordingly, the present disclosure allows the handling of bulk goods without any further filling into standardized steel containers. The present disclosure mentions by way of example the mixing of bulk goods in a flexible package, which flexible package is spread out in a frame so as to forcibly assume, at least almost, a predefined body shape. The frame is then moved into the mixer in a manner in which otherwise the known rigid mixing containers would have to be clamped.

[0030] Advantageous methods according to the present disclosure ensure a clinging on or otherwise spreading out of the lateral walls and/or the bottom of the flexible package to form flat partial surfaces.
