Description

According to an embodiment of the present invention, the container lid is made of a thermoplastic and is manufactured by an injection molding method or a blow molding method, and the inliner is airtight and liquid-tight in the outer peripheral region of the container lid. Welded or glued. If both the inliner and the container lid are made of plastic, it is advantageous if the inliner and the container lid are welded together or if the inliner is welded to the edge of the container lid.

In FIG. 1, a container with a lid according to an advantageous embodiment of the invention is indicated by the reference numeral 10, which has a cylindrical shape with a covered container lid 14 and a tension ring closing member 16. This is a 220 liter container with a lid. The container lid 14 has a central flat disk-shaped lid 18 with two plug openings arranged diametrically facing each other, and a U-shaped lid edge 20 that opens downward. The lid edge 20 has an outer annular member 22 and an inner annular member 24 (FIG. 5). The center disk-shaped lid 18 is configured to be slightly higher than the outer flat annular band 32 extending in an annular shape. Two plug openings that are diametrically opposed to each other at the transition from the outer annular band 32 to the central disc-shaped lid 18 and can be closed air-tight and liquid-tight by one plug plug 38, respectively. However, in the closed state, the surface of the screwed plug plug 38 is flush with the surfaces of the tension ring closing member 16 and the disc-shaped lid 18 that are fitted. It is supposed to be located in. A solid annular bottom rolling ring or foot ring on the inner edge of the container body 12 for good shape stability, high stability, and good rollability in a tilted state of the filled container 40 is arranged. The tension ring closure member 16 has an upper leg that overlaps the U-shaped lid edge 20 and a lower leg disposed on the outer peripheral wall of the container body 12 above the container opening 36 and substantially radially. It overlaps with the peripheral flange 34 protruding outward.

FIG. 4 shows a book having a container body (drum body) 12, a container lid 14 fitted over the container body 12, and an inliner (plastic film bag) 26 welded to the container lid 14. 1 shows a cylindrical lidded container 10 according to an advantageous embodiment of the invention; The capacity of the lidded container is about 220 liters or 55 US gallons. The lidded container 10, the height is 89 0 mm and an outer diameter of 585 mm, have substantially the same dimensions as the corresponding steel drum (drum), handled by the same drum gripper as those used in steel drums be able to.
