This multiple effect of the invention is the initially flat protruding flange for example The container is particularly advantageous when the io is in the manner of an already known method (USA, receiving part with another, axially over the patent specification 3 233 386) only after placement Support part upwardly protruding head part connected to the upper support part edge folded over and then in Abden is. Especially with such a bottle-like conversion of the other known method for this foäitem is not only taken care of because of an increased internal pressure that a bead of the flange into the komder larger Füllgiitsäule on the bottom of the press-on support part material partially penetrates. Acceptance part load, but is the increased product- more cooling takes place in order to avoid that volume when transporting and handling the container inadvertently recovers the areas mentioned also an increased tendency to form, but rather stiff enough after cooling down pulling the receiving part from the support part. to maintain this state.

In the invention, however, it is ensured that the use of a is particularly advantageous Also such a bottle-like container is not stepped die for carrying out this * process, the receiving part tends to move away from the support part ie. for flipping the flange and for pressing in solves. So that the manufacturing costs of such a bead in the compressible support part material, bottle-like container are low, recommends its cylindrical inner part as a cooling surface the manufacture, the receiving part and the head as forms. Although not a part for a step die is stressed separately by deep drawing and relevant element protection, it has ßendes connecting, in particular welding, has shown that its application in particular Area of the upper, free edge of the receiving part then for a rapid implementation of the above and in the area of the lower, free edge of the top method contributes when the inner part is used as a cooling part.

According to FIG. 3, both the receiving part 3 as a housing, which is open at the bottom and the top part 4 with flanges 5 'and 5 "are connected to a hose 11, which can be seen with one another through a High frequency or compressed air source can be connected. The ultrasonic welds are connected, the housing can be moved in relation to the container, has radial dimension S of about 2.0 mm. That is fixed during the folding down process, and the material of the flanges 5 'and 5 "is a bit thicker, although by a non-illustrated actuator in the wall parts of the receiving part 1, in the whole mechanism of conventional design, z.

the materials fused together; The inner profile of the lower, ie outward flanges 5 'and 5 ", can therefore then be viewed as an open part made up of a single double flange conically outward, which in the opening catching surface 12, a cylindrical leading surface, is simply referred to as a flange 13, a conical outward opening during welding, as a result of the pressure of the flange bending surface 14 and a cylindrical welding electrode, there is a certain material flow ao see flange smoothing and guide surface 15, which reduces the thickness of the flange 5 (which the The shape and the radial dimension R of the downward thickness T will be approximately 0.9 mm. With the folded or folded flange intended for this purpose, bulges 6.7 are formed on each side radially on the outside Initial stage of the melting tool as a result of the flow of the flange folding process with protruding flange 5, plastic material, 25 during the right side The lower annular bead 6 is shown according to the tool when the flange is folded down, the invention used to press in the receiving part 3 on the outside of the bead 6 'and to fasten the flange to the support part 2 by means of the work. By folding down the tool has cooled down. When the cooling process has ended and the flange 5, which is not yet sufficiently dimensionally stable, is safely brought into its final position on the outside of the support part 2 and by pressing in 30 position, the completely container of the bead 6, which is slightly deformed and in with HiUe des Connected to a compressed air source Fig. 4 therefore referred to as a deformed bead 6 'hose 11 is ejected from the stepped die 10, into the fibrous and therefore compressible The pouring opening of the head part 4, the receiving part 3 is securely anchored. 35 if he has one, provided with a cover.
