"flexible collapsible container" "

The invention relates to flexible containers made of rubberized fabric or a similar pliable material, which can be collapsed when empty. The invention is based on such containers of a known type, which consist of a prismatic, normally ζ 'cylindrical square body made of rubberized fabric or the like, which is closed at one or both ends by means of cover parts, of which at least one part is flat is,

In such known containers, the union takes place

the cover parts with the dumbbell body in the most varied of ways, e.g. by an adhesive connection or using of hinges and hooks * For all conventional containers of this kind, an intricate device is required for the safe union of the container parts with one another, by which not only the manufacturing costs of the containers are high but also their maintenance becomes difficult and expensive as soon as they are due to certain reasons, e.g. possible damage are repaired outside.

The object of the invention is therefore to eliminate these disadvantages and to construct containers of the present type in such a way that that they are easy to manufacture and maintain at low cost.

For this purpose, a flexible collapsible container, consisting of a square body, is characterized Flexible plastic and a flat cover part for the open end (s) of this cantilever body and parts for the detachable, sealed connection of this or these cover parts of a pair of essentially equally large rigid bridging rings, which are tensioned against each other in the axial direction can be, and an associated rigid intermediate ring exist, and that the associated free end of the jacket body between the two pressure rings on the one hand and the Intermediate ring is held clamped on the other hand.

Another feature of the invention of the collapsible tank is that for clamping the two pressure rings together against each other screw elements are provided.

Another feature of the invention is characterized in that one of the two pressure rings feet with the flat Cover part is connected.

According to a further feature of the invention, the intermediate ring feet are connected to the flat cover part.

Another feature of the invention is characterized by » that the flat cover part is made of flexible material and at the same time with the "unordered end of the jacket body rs between the pressure ring pair and the intermediate ring each triangular lattice is held clamped.

The invention is explained below with reference to schematic, non-scaled drawings for exemplary embodiments.

Fig. 2, 3 and 4 further embodiments for the union of the casing body and cover part,

The container shown has for all exemplary embodiments a cylindrical shell body 1 made of rubberized »fabric or a» similar flexible material, as well as flat Cover parts 2 made of the same or similar material.

Body 1, two pressure rings 3 and 3 'and an intermediate ring 4 are provided, all of which consist of a rigid) preferably metallic material. The two pressure rings 3t 3 ^f have a number of axial openings which are aligned with one another in the assembly state and serve to accommodate clamping bolts 5.

The diameters of these rings 3 '3' and 4 Bind selected so that they hold securely clamped in the trefoil in a tensioned state, the free end edges of the dumbbell body 1 between them, in the example of Pig. 1 together with a separate cover part 2 each. Purely in this exemplary embodiment, the container according to the invention thus has the following components:

A cylindrical casing body 1 made of rubberized fabric,

two sets of pressure ring pairs 3ι 3 'essentially the same size,

two intermediate rings 4 of essentially the same dimensions,

two flat cover parts 2 made of rubberized fabric, which are made of disk-shaped membranes ie essentially the same dimensions can be formed, and

two sets of clamping bolts 5 of normally the same dimensions.

To assemble the container, these files are releasably connected to one another; each of these can easily if necessary replaced or exchanged.

The assembly of the container is done as follows:

First, a pressure ring 3 ^{1 is} attached to one end of the cylindrical external body 1, then the intermediate ring 4 for this end of the container on the cover part 2

placed and the parts 2, 4 together in the interior of the Shell body 1 up to the stop against the shell body covered pressure ring 3 'inserted.

Then the other pressure ring 3 of this pair is on the The outside of the cylindrical casing body 1 is pushed up to the stop against the intermediate ring 4 covered by the cover part 2 and casing body 1. Now the tension bolts 5 in the aligned openings of the Pressure rings 3 and 3 'inserted and tightened by end screws until the intermediate ring 4 with cover part 2 and dumbbell body 1 is held securely between the pressure rings 3 »3 ', the flexible walls of parts 1 and 2 so are pressed together that at the same time an effective seal of the container is ensured.

In the example according to Pig. 1 is the arrangement of the parts of the container is different in that once, e.g. above, the outer surface of the cover part 2 on the inside of the container, and on the other hand, e.g. below, the outer surface of the cover part 2 on the outside of the container.

Of course, the parts can also be arranged in such a way that the two cover parts 2 at both ends of the container are directed either outwards or inwards.

In the illustrated in Fig. 2 modified Ausführungeform no separate cover parts 2 of resilient V / erkBtoff between the triangular structure of the rings are 31 3> held clamped 'but hb the outermost rigid pressure ring is firmly 3 of this association and is sealed at its one side with a Washer 6 made of rigid material ver ~

bound, e.g. by soldering or welding, if the parts 3 and 6 are made of suitable metallic materials · The triangular bond therefore only spans the relevant one free end of the Mantelkörperβ 1 between them. the Clamping bolts 5 are also present in this Pail, but not shown specifically.

In the embodiment shown in FIG opposite Pig. 2 the rigid disk 16 firmly connected to the intermediate ring. Otherwise, the holder of the Han-P telkörpers 1 is designed accordingly as in Pig · 2. Sat only the cross section of the compression length 3i V is smaller than that of the intermediate ring 4.

In the Pig. 4 is a cylindrical dumbbell body 1 between two inner pressure rings 7t 7 'and an outer intermediate ring 4 held clamped »The ring 7 is with continuous axial openings and the ring 7 * with aligned threaded holes in the pore provided by blind holes, so that screws 8 with her Threaded part are screwed into these threaded holes. A disk 26 made of rigid material is a fixed bit of the pressure ring 7 in the case of metallic materials for the parts ™ 7 * and 26 connected by soldering or welding. The assembly of the parts is evident from the drawing.

There can also be provided a further modification, not shown in the drawings, of this latter embodiment, in which the disc 26 is made of flexible material and with its edges that are then attached to the contact cylindrical shell body, is held between the intermediate ring 4 and the pressure rings 7, 7 *.

Although not shown, the invention also includes all such AusfUhrungsformen in which both the pressure and the intermediate rings have a different cross-section than the circular shape, and also those embodiments in which means are provided for securing the retention of the rings to one another , the bolts or Screws are equivalent. In addition, the container of the invention can easily have a cross section in the form of a pyramid or a truncated cone.
