Embodiment Construction

[0019] Figure 1a A lid element 10 of a pressure vessel, in particular a beverage can, according to the state of the art is shown, wherein the lid surface 11 is usually made of aluminum sheet metal or other similar metal and is connected by a flange 12 to a vessel wall 13 of the pressure vessel.

[0020] The closure device 14 is made of plastic, such as polypropylene (PP), and is arranged on the underside of the cover surface 11 . The purpose of this closure device 14 is to tightly seal the drinking opening 15 arranged in the cover surface 11 in the closed state of the pressure vessel by means of a seal 16 arranged in the peripheral region. In this case, the seal 16 rests on the inside of the cover surface 11 against the sealing surface 16a. Such as Figure 1a As indicated, the pressure vessel has not yet undergone any heat treatment.

[0021] Figure 1b show Figure 1a The cover element 10, which is undergoing heat treatment. Figure 1b It is clearly shown that due to t...

Abstract

The invention relates to a filled and reclosable pressure vessel, wherein the body is filled with a fluid, closed non-removably by means of a cover element (10, 100) and subjected to heat treatment, the pressure vessel comprising a cover surface (11, 110 ) and the closure device (14) made of plastic as cover element (10, 100), and at least one seal (16) arranged on the closure device (14), the cover element (10, 100) in such a way is arranged, that is, the closure device (14) faces the interior of the sealed pressure vessel, wherein the cover surface (11, 110) and the closure device (14) are arranged such that the cover surface (11, 110) has an approximate passage between the cover surface ( 11, 110) on the first surface (111) of at least one sealing surface (16a) extending the first distance (a1) of the first reference plane (E1), and the closing device (14) from passing through the at least one sealing member ( 16) The extended second reference plane extends a second distance, the first distance (al) being selected to be greater than the second distance.

Description

technical field [0001] The invention relates to a method for producing a filled and reclosable pressure container, wherein a container body having a cylindrical jacket and a bottom part is filled with a fluid, on which the container body is non-detachably closed by a cover element, Subsequently optionally subjected to a heat treatment, the cover element has a cover surface preferably made of metal and a closure device made of plastic is used as the cover element, the closure device being fastened to a first surface of the cover surface and arranged on the closure device At least one seal member is in contact with at least one sealing surface provided on a first surface of the cover surface, the cover element is composed of the cover surface and a closure device arranged to close the pressure vessel, the cover element is arranged to make the closure when closing the pressure vessel The device faces the interior of the sealed pressure vessel. Background technique [0002] The...
