Definitions

  • the invention relates to a container made of sheet metal, such as a bucket, hobbock or the like. With a push-in lid, which has the features of the preamble of claim 1.
  • the edge of the container has an outwardly rolled flange on which the essentially radially extending flange of the lid rests with the interposition of a flat seal.
  • the essentially C-shaped ring is pushed and deformed from the outside over the connection point in such a way that the lower leg engages under the rolled edge, while the upper leg extends over the entire radial extent of the cover flange.
  • the outer rim of the container edge is elongated in the axial direction to a long oval shape.
  • the upper end is overlapped by the cross-sectionally U-shaped flange of the cover with the interposition of a seal.
  • the folding ring is accordingly designed as a C-cross-sectional shape which is stretched in the axial direction and slightly overlaps the connection above and below. This training, too, cannot solve the problems shown.
  • the folding ring is designed so that its upper leg extends downward over a considerable axial length along the core wall. This gives you greater stability. Nevertheless, there is still the risk that the bordering or the cover flange and the folding ring will be damaged in such a way that they will no longer guarantee a secure and tight connection if the external load is increased.
  • the spiral shape of the border is known in principle.
  • the sheet metal areas lie closely together in the spiral part and with corresponding flank pressure, and also in the transition area between the cylindrical fuselage wall and the beginning of the spiral border.
  • This bordering thus has an extraordinarily high dimensional stability and high strength, which also considerably increases the stability and the resistance to deformation of the container edge.
  • the edge flange of the press-in lid is bent outward in a circular arc with the bordering of the corresponding curvature, the outer leg firmly nestling against the radially outer region of the bordering of the container up to a point below the horizontal central plane.
  • the space between the bordering and the curvature of the edge flange of the lid is expediently completely filled by the mass of the sealing ring in the closed state of the container, which, from its original shape, e.g. that of an O-ring is deformed accordingly under the closing pressure.
  • the fold ring which is essentially C-shaped in cross section, is designed in a special way to increase the strength of the closure, specifically according to claims 3 to 5.
  • the arrangement is expediently such that the horizontal center plane of the circular arc, which determines the curvature of the edge flange of the cover, touches the upper region of the spiral border or is only slightly above or below the tangential point of contact.
  • the container made of sheet metal is designated by 1 and the associated press-in cover by 2.
  • the press-in cover lies closely with a core wall region and under friction against the fuselage wall 9 of the container and merges into the cover mirror 4 via a circumferential shoulder 5, which can be of any shape.
  • the shoulder 5 facilitates the stacking of the lids and the removal of individual lids from this stack.
  • the edge region of the cover 2 has an edge flange 6 bent outward in the shape of a circular arc.
  • the horizontal central plane of the radius of curvature determining the edge flange is designated by 16.
  • the edge flange has an outer cylindrical flange section 19 which projects considerably downwards.
  • the container body 9 merges continuously into a spiral edge curl or border 10, in which the sheet metal areas lie tightly against one another with appropriate flank pressure, and also in the area of the horizontal central plane 15 of the border, in which its sheet metal areas on the fuselage wall 9 bear under flank pressure.
  • the free edge 11 the border 10 extends a piece 12 beyond the horizontal central plane 15.
  • the area 8 of the edge flange 6 of the cover 2 projecting below the horizontal central plane 15 is pressed against the circumference of the border 10 with the free edge 7 with flank pressure.
  • a sealing ring is inserted in the space between the edge flange 6 and the border 10, which in the unloaded state e.g. is an O-ring.
  • the cross section of the sealing ring is deformed under the closing pressure so that the mass 25 of the sealing ring essentially fills the entire space between the edge flange 6 and the flange 10, as shown in the figure.
  • the parts are held together in this position by a radially inwardly open folding ring 3 with a C-shaped cross section.
  • the folding ring 3 nestles closely over the entire length of the edge flange 6 to the free edge 7 thereof under flank pressure against the edge flange 6. Beyond the free edge 7, the lower leg 18 of the tension ring 3 is drawn in continuously until it is pressed against the circumference of the border 10 and lies against the border up to the free edge 20 of the tension ring.
  • the edge region of the clamping ring 3 extends deep into the bordering channel 21, which is formed between the fuselage edge 9 and bordering 10.
  • the folding ring 3 also bears against the cylindrical section 19 of the edge flange 6 of the cover 2 with flank pressure with its section 17 and then also closely follows the arcuate cross-sectional curvature of the edge flange with flank pressure.
  • the upper leg 13 of the folding ring is inwardly around the edge flange so far that the upper free edge of the folding ring 3 approximately in the horizontal central plane 16 of the arc defining the curvature of the edge flange 6 comes to rest.
  • the container, lid and clamping ring are made of sheet metal.
  • the sheet metal can be chosen to be relatively thin, since the shape and dimensioning of the parts of the closure have an extraordinarily high stability and high strength against external forces.
