Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) Further properties and features of preferred embodiments of the present invention emerge from the description below of preferred embodiments with reference to the attached figures, wherein individual features of embodiments can be combined with one another to form new embodiments. In the figures:

(2) FIG. 1 shows a cross-sectional view of a first embodiment of the container assembly;

(3) FIG. 2 shows an exploded illustration of a sectioned partial view of the first embodiment of the invention; and

(4) FIG. 3 shows a sectioned partial view of a further embodiment of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(5) FIG. 1 illustrates a cross-sectional view of a first preferred embodiment of the container assembly according to the invention. The latter is expediently designed to be substantially rotationally symmetrical about an axis of symmetry X and has a first region 2 and a second region 4. The first region 2 is designed here in such a manner that said region substantially corresponds to a lateral surface of a cylinder. The second region 4 is arranged here on the first region 2 in such a manner that said second region forms a base or cover, and therefore the first region 2 and the second region 4 enclose a container interior I and separate the latter from a container exterior or container outer side A.

(6) The first region 2 and the second region 4 are connected to each other via an adjoining region 6. For this purpose, the first region 2 has a first joining portion 8. The second region 4 correspondingly has a second joining portion 10.

(7) In the embodiment illustrated, the second region 4 has a concave portion 12 which is curved toward the container interior I.

(8) As is apparent, the first joining portion 8 encloses the second joining portion 10 in a radial direction R, and thereforeas seen in the radial direction Rthe first joining portion 8 is arranged outside the second joining portion 10.

(9) FIG. 2 illustrates an enlarged cross-sectional view of the joining region 6. In this case, the first region 2 is connected to the second region 4 both via a circumferential joining point 14 and via an end-side joining point 16. It goes without saying that also only one of the joining points 14, 16 can be provided. In order to provide the circumferential joining point, the first joining portion 8 has a circumferential joining surface 18 opposite which and particularly advantageously parallel to which the second region 4 has a second circumferential joining surface 20. As a result, the circumferential joining point 14 forms a rotationally symmetrical ring about the axis of symmetry X.

(10) In order to form the end-side joining point 16, the first joining portion 8 has a first end-side joining surface 22. In a corresponding manner, the second joining portion 10 has a second end-side joining surface 24. In the embodiment illustrated, the end-side joining surfaces 22, 24 are formed substantially parallel to each other. It goes without saying that said joining surfaces, however, can also be at an angle to each other which can advantageously be plus/minus 5 to the parallel or radial R.

(11) The second joining portion 10 is adjoined by an adjacent portion 26 which is formed transversely with respect to the second joining portion 10. In a preferred embodiment, the second joining portion 10 is at an angle of between 45 and 110as measured from the container outer side Ato the adjacent portion 26.

(12) FIG. 3 illustrates a partial cross-sectional view of a further embodiment of the container assembly according to the invention. In contrast to the embodiment illustrated in FIG. 1, the second joining portion 10 encloses the first joining portion 8, i.e. is arranged outside the first joining portion 10, as seen in the radial direction R. Furthermore, only one circumferential joining point 14 is provided. Outside the second joining portion 10 and the adjacent portion 26, the second region 4 is formed with a convex portion 28 which is curved outward toward a container outer side A.

(13) In the illustrated embodiment, the wall thickness of the first region 2 and of the second region 4 of the respective joining portion 8, 10 is of increased design. It is particularly advantageous if the increase of the wall thickness of the first joining portion takes place in a direction which lies opposite the second joining portion 10, and therefore the first circumferential joining surface 18 is substantially aligned with the adjoining circumferential surface of the first region 2. In the case of a circular-cylindrical configuration, the radius of the circumferential surface on which the first circumferential joining surface 18 is provided would thus be substantially constant along the axis of symmetry X.
