CLAIMS

1. Shaped, compressible, flexible container of relatively thick a d rigid material intended for fluids such as nutrient solution, infusion solution, blood, etc., whereby the container includes a container body (1) forming a fluid chamber (2) where the con- tainer body is provided with a first end portion (3) and with a second end portion (5), in addition to which the container body is formed by two opposite walls (7,8) which are joined at two longitudinal lateral edges (9,10) which connect the two end portions (3,5) to one another, whereby the container body forms an intermediate section (11) which passes into a first end section (12) and a second end section (13) which include primarily flat wall portions (14 a,b and 16 a,b), which pairwise form an angle with one another and where the container includes a suspension device (6) connected to the first end portion (3) and an empty- ing device (4) connected to the second end portion (5), which emptying device is connected to the interior of the fluid chamber, characterized in that the end portions (3,5) comprise primarily tubular devices by means of which the primarily flat wall portions (14 a,b and 16 a,b) are pairwise joined to one another and by means of which the primarily flat wall portions in the region next to the tubular devices are located pairwise near one another or primarily abut one another, that the tubular devices form primarily control devices stable in shape which
during emptying and a partial vacuum created thereby in the
interior of the container allows a motion towards one another of said v/al 1 portions (14 a,b and 16 a,b), whereby during the
emptying of the container there is formed in one (14 a,b) of said wall portions a primarily arc-shaped reversal zone (24) facing the opposite wall, v/hich zone during the emptying of the container is moved primarily in a direction towards the second end portion (5) of the container body and thus brings the container wall containing the reversal zone to positions close to the opposite container wall.

2. Container as claimed in claim 1, characterized in that in the intermediate section (11) each wall (7,8) includes a central primarily flat wall portion (25,26) which by means of lateral walls (27 a,b; 28 a,b) joins each central v/ l 1 portion to longi- tudinal lateral edges (9,10) of the container body and that in the filled container the lateral wall's form an angle with one another.

3. Container as claimed in claim 2, characterized in that the lateral walls (27,28) join the central wall portions (25,26) to the longitudinal lateral edges along their entire length.

4. Container as claimed in claim 2, characterized in that lateral walls (27 a,b and 28 a,b) located next to one another form an angle with one another which as a rule is located in the range
o o
20-120 and preferably located in the range 40-80 .

5. Container as claimed in claim 1, characterized in that wall portions (14 a,b and 16 a,b) of the end sections located next to one another form an angle with one another which as a rule is
o
located in the range 40-120 and preferably located in the range

60-100°.

6. Container as claimed in claim 1, characterized in that of
opposite walls (7,8) of the container body one of the walls is designed for greater mechanical stability compared with the
other.

7. Container as claimed in claim 1, characterized in that of
opposite walls (7,8) of the container body one of the walls (7) is designed for greater mechanical stability in a region from the first end section (12) to a region in the central wall portion (25) of the wall (7) and the other wall (8) is designed for greater mechanical stability in a region from the second end
section (13) to a region in the central wall portion (26) of the wall (8).

8. Container as claimed in claim 6 or 7, characterized in that in order to obtain the greater mechanical stability the wall in question is disposed with increased wall thickness, with reinforcement profiles e.g. with grooves or with bands of thicker material.

9. Container as claimed in claim 6 or 7, characterized in that one of the walls in the pairwise primarily flat wall portions (14 a,b and 16 a,b) is in at least one of the pairs the one wall disposed with an arc-shaped profile facing the opposing wall.

10. Container as claimed in claim 1, characterized in that the tubular edges (3,5) of the end portions are disposed with stiffening material accumulations (29).
