[Conventional technology]

Generally, the top of this type of stoppered container has two flanges with different diameters. ing. These flanges are tightly screened by closure screws in conjunction with the packing. It is possible to disconnect. In this case a larger diameter flange (usually 2'' wide) is used to fill Smaller diameter flanges (usually 3/4'' wide) are used for used to evacuate the container beforehand and to introduce air when emptying the container. It will be done. This kind of flange is equipped with a male thread and a nut tensioning the packing. It can be tightly combined with the upper part by the considerable effort required for this To reduce this, push-in flanges and welded flanges are used. Push-in flap The flange and weld flange can be tightly press-fitted or welded into the upper base. example Welded flanges require significantly less manufacturing cost than threaded and push-in flanges. Since the stress is low and there is no need to provide a packing ring, the products to be transported are This is advantageous when the material of the sealing ring is corroded. However, the known Welded packings also proved cumbersome to manufacture. For example, put a suitable filling hole in the top bottom Not only does it need to be punched out, but the edges of this fill hole protrude from the top bottom surface. The edges may be raised and the edge areas may be folded. Furthermore, this type of flan The relatively wide mounting surface of the cage requires a large amount of material, which requires processing by cutting and/or Deformation processing is troublesome. Containers with closures equipped with this type of flange are expensive. So, there is competition only in certain cases.
