Description

The invention relates to a flexible container for chemically pharmaceutical solids, preferably with integrated containment interface, cf. The preamble of claim 1. It is about internal and external transport, especially in the public sector. For this purpose, such containers usually, in conjunction with an associated packaging, a UN transport authorization for hazardous substances. A generic storage is a temporary storage in the production process as well as a long-term storage as primary packaging. In addition to the comparatively simple filling and emptying processes, the generic handling also involves considerably more complex mixing methods. Known containers and mixing or refilling processes in these areas are often expensive and inflexible. Here is a need for improvement. Such containers are in the DE 603 13 536 T2 and the DE 602 01 032 T2 disclosed.

This problem is solved by a container according to claim 1 comprising its characterizing features and by the use according to claim 10.

Advantageous embodiments are specified in the subclaims.

Flexible containers according to the invention are suitable for use as hazardous substance containers in the specified underpressure and overpressure. Whether with or without or even with multiple containment interfaces, the variants of the invention are characterized by a particularly simple handling. The flexible container is very easy to unfold in an open state for filling and just as easy to fold. Serve for that according to the invention fastening means at certain positions. Particular wall structures of preferred embodiments support easy handling.

A special embodiment of containers according to the invention is optimized for use with a support and handling frame, optimized in a particular application for mixing processes. In this case, outer pockets for flat baffles of support and handling frame and / or straps for positioning and fixation are integrated into the flexible container, in order to then allow the mixing process fixed boundary conditions.

An inventive container 1, 1 ', 1 ", 1"', see. four different from each other by apostrophes embodiments of the FIGS. 1 to 6 , includes combinations of features of the following list:

• three-dimensional contour in the filled or fillable state (cube / cuboid with truncated pyramid),
• inner foil package 3 (inner liner),
• outboard support fabric 2 (outer liner),
• Inner and outer liner sewn together at the edges 5 and glued together flat,
• Inner and outer liner as well as connection to each other (seam, adhesive) static dissipative,
• integrated suspension lugs 7 for different handling tasks,
• integrated containment interface 10, in particular for docking, for example by means of a flap technology 20.

An inventive flexible container 1 according to the first embodiment is in an application in FIG. 2 shown, but already basically in slightly different dimensions of the overview FIG. 1 to remove on the left. In FIG. 1 it is shown ready for filling in an open condition. In FIG. 2 it is emptied after it has been connected by means of a containment interface 10 to a system and its flap technology 20.

Conventional forms of such containers are well known from the prior art and suitable in large parts to the inventive design. A main purpose of the invention is to improve handling over the prior art. Thus, the first embodiment achieves a very safe and simple recording in a straightforward frame 15. The flexible container 1 is during emptying already because of its structure but also because of its fasteners almost completely or completely emptied for holding up, because dead spaces are avoided.

The container 1 has four side surfaces 11 around a filling axis or emptying direction F. Around the filling axis F, they together enclose a filling space, which filling space is closed or closable at the top with a bottom surface 12 and at the bottom with the containment interface 10. If, in other forms, a floor surface were missing at the top, a point collision of the side surfaces (not shown) in the context of the invention above could close off the filling space.

In the case of the first embodiment extends along a surface longitudinal line 6.2 a in FIG. 2 visible side surface 11 in the horizontal direction and transverse to the emptying direction F a draw-compound as a suspension. On a in FIG. 2 invisible opposite, namely hidden back extends over the local side surface of the container 1 as well almost completely over the entire width of another stretch connecting means as a suspension. The two oppositely oriented, elongated connecting means for receiving transverse mandrels of the frame 15 are presently designed as loops or tabs.

The connecting means are suitable according to the invention to be able to attach the container 1 in the open or initially closed and filled state on the frame 15. On the other hand, the two connecting means before filling serve to bring the empty, flattened container 1 with a handle, namely a pulling apart of two mandrels inserted into the connecting means in the open state. Thirdly, the connecting means serve to empty the container 1, which is still empty when it is still open to bring a handle back into a flattened state, namely by means of a collapse of the mandrels.

This succeeds particularly well in the illustrated embodiment, because the container consists of an inner film layer and an outer fabric layer. These layers are partially glued together. The fabric of the outer fabric layer has in the case of the two equipped with the horizontal fasteners side surfaces a dominant cross structure, which hold the equipped with fasteners side surfaces 11 strack. In further such variants, the special fabric was dispensed with and sufficient stiffening was achieved even with sewn on straight straps connecting means. The in between in the direction of the FIG. 1 extending side surfaces (not visible), however, are preferably reinforced longitudinally oriented, so that tend to buckle along the filling direction F, as soon as at FIG. 1 Bottom mounted interface 10 is pulled.

According to the second embodiment FIG. 4 Tabs 8 ', 9' attached as a connecting means to the container. At its bottom surface 12 'is per side edge 6.1' an edge tab 8 'attached, which serve for hanging and clamping. In the inner area 4 'of the bottom surface 12' is an internal flap 9 'is arranged, which helps as a pull tab to bring the emptied, still in the open state container 1' in a flattened state with a handle again.

The interface 10 is according to the first embodiment ( FIG. 2 ) is formed as a containment interface 10. After a third in FIG. 3 illustrated embodiment, a tri-clamp flange 13 "is integrated as a lower terminal end, namely for docking to an inlet port.

This in FIG. 6 illustrated fourth embodiment of a flexible container has incorporated a Einknickstruktur 26 in two opposite side surfaces without fastening means, which extends at least roughly along the filling direction F. It is a targeted thinning parallel warp threads 22 of the outer fabric, which dictates a preferred Einknicklinie 28. A stiffening structure is incorporated in the other two opposite side surfaces 11 '' with a lower tab for extended pulling, in which stretched threads or weft threads 24 of the fabric counteract buckling.

Depending on the process requirement, the container 1 "'is made in layers of electrically dissipative material.

In FIG. 7 is a section of the upper fabric of a side surface 11 shown greatly enlarged by a basic illustration. It can be seen that the fabric has a continuous weft thread 24 and a number of warp threads 22 extending substantially perpendicular thereto and parallel to one another. The warp threads 22 are alternately guided below and above the weft thread 24. Furthermore, in FIG. 7 It can be seen that the number of warp threads 22 decreases towards the center of the side surface 11, so that the distance between two adjacent warp threads 22 increases. The greater the distance of the warp threads 22, the easier it is for the side face to be bent along the warp threads 22. This results in a Einknickstruktur 26, which defines a Einknicklinie 28.
