DESCRIPTION OF THE EMBODIMENTS

(3) FIG. 1 (FIG. 1A to 1F) illustrates the method according to the invention in accordance with a first embodiment.

(4) First, the lid panel 110 is provided in the first step according to FIG. 1A. A pouring opening 112 and a guide opening 114 are provided in it.

(5) In the next step, bringing together of an inner slide piece 120 and a side of the lid panel 110 that is provided as a container inner face 116 takes place according to FIG. 1B.

(6) Subsequently, an outer slide piece 130 and a side of the lid panel 110 provided as a container outer face 118 are brought together according to FIG. 1C.

(7) Then, connecting of the inner slide piece 120 with the outer slide piece 130 via at least one connection element 132 disposed through the guide opening 114 takes place according to FIG. 1D.

(8) Furthermore, a closure element 140 and the side of the lid panel 110 that is provided as a container inner face 116 will then be brought together with the inner slide piece 120 according to FIG. 1E. The closure element has a groove 142 whose cross-section form is formed in a way that is complementary to a cross-section, form of a slide nose 122 disposed on the inner slide piece 120.

(9) Finally, the establishment of a coupling between the closure element 140 and the inner slide piece 120, in this example via a slide nose 122 that will be inserted in the groove 142 of the closure element, takes place according to FIG. 1F.

(10) FIG. 2 (FIGS. 2A to 2E) illustrates the method according to the invention in accordance with a second embodiment.

(12) FIG. 2B shows a work piece carrier 250. Troughs 251 are to be provided in it (four troughs in this example) that contain, in turn, cavities 252. In the cavities 252, inner slide pieces can be installed after previous alignment and hence fixed in their position. The troughs 251 can integrate lid panels and/or closure elements.

(13) FIG. 2C shows an inner slide piece 220 in a top view that is equipped in this embodiment with four laterally disposed slide noses 222. Furthermore, the inner slide piece 220 has openings 224 in which respective connection pins of an outer slide piece can be inserted.

(14) FIG. 2D shows such an outer slide piece 230 in a top view (top) and in a lateral view (bottom). This outer slide piece 230 has pins 232 that can be inserted in the openings 224 of the inner slide piece 220 for the connection process. Further, the outer slide piece 230 comprises a hinged piece section 234 and a pin 238 that is formed on it and that can be integrated in a respective ventilation opening of the closure element. In addition, detachable parts 236 of the outer slide piece 230 are to be provided, which are connected to the hinged piece section 234 via crosspieces. The outer slide piece has a tapered area 235 around which the hinged piece section 234c can be folded.

(15) FIG. 2E shows a top view of the closure element 240 that has the groove 242 to integrate the slide noses 222 of the inner slide piece 220. Furthermore, a ventilation opening 244 and two riveting pins 246 are to be provided. During manufacturing of the lid, the riveting pins 246 are connected to each other with the detachable parts 236 of the outer slide piece through welding, e.g. by means of ultrasound. Therefore, they can for example be inserted in openings 237 before.
