Definitions

• the invention is concerned with the formation of a position fixation of a grip tab on a sheet metal lid for attachment to a body of a beverage can.
• the person skilled in the art speaks of a SOT (Stay on Tab), which is provided for opening an opening area in the cover mirror (mostly called “panel”).
• SOT Stay on Tab
• the handle tab is lifted with a vertically oriented tilting movement, gripped at one end of the handle, in order to break open the opening area along a weakening line (mostly called score line) with its opening end.
• the invention is faced with the technical problem of achieving the same effect, but improving the manufacture and the reliability of the turnstile or the orientation of the mounted handle tab.
• the protrusion can thus be formed in one piece with the sheet metal cover, as is the fastening point due to the one-piece design for the attachment tab of the grip tab.
• the projection can be strip-shaped (line-shaped) and preferably oriented transversely and / or parallel to a longitudinal extension of the grip tab (longitudinal axis or longitudinal plane), wherein it engages on a correspondingly aligned edge of the attachment section for its blocking effect or is formed very closely adjacent to it , In a longitudinal extension, the projection can extend over more than 30%, preferably over more than 50% to more than 80%, of the width of the attachment tab (claim 5, 36).
• the longitudinal extension is shorter than the longitudinal extension of the attachment tab (rivet island) of the grip tab, preferably at a point as far away from the attachment point as possible, but at a great distance is only so large that at least a section of the two border lines is able to rest against the at least one projection at the beginning of a rotary movement (claim 38).
• the height extension of the at least one projection should at least correspond to the sheet thickness of the attachment section (claim 20, claim 21), preferably can be made slightly to significantly higher in order to obtain a reliable position fixation, which is not impaired by this, that the handle section is actuated or raised after the attachment section is located reliably beyond the attachment point in a flat position to the panel section in the vicinity of the rivet (button coin area).
• the provision of a plurality of projections is possible, it not being necessary for all the projections to be assigned to the same outer edge section of the fastening section (claims 6 to 9).
• the projections can also be designed differently, such as stripes, round to oval or combined. If a rectilinear outer edge section of the attachment section is provided, a rectilinear (strip-shaped) projection design can be advantageous.
• the linear stripe design can also be achieved by stringing together at least two point-like projections, which then form a group which is assigned to the same outer edge of the attachment section.
• the attachment section as a fastening tab is connected as a hinge line to the rest of the grip tab, ie in one piece (claim 13, 11). It is thus formed between the opening section (the burglary nose) and the handle section, which is preferably provided with an opening.
• the attachment section is essentially rectangular, the essentially rectangular, flat attachment section is formed using the hinge line and three edge lines (claim 12).
• this flat section is of square design, the rivet head not being located in the center after assembly, but rather closer to the joint line.
• the distance of the outward facing Edge edge is accordingly greater than half the longitudinal extent of the attachment section, so that a correspondingly improved force effect arises if a projection on the panel can be assigned to the edge edge that is furthest away from the fastening point.
• At least one projection which is asymmetrical in cross section and which is designed steeper on its flank facing the attachment section than the flank which is more distant therefrom (claims 17, 18, 19 and 23 or 24).
• Such a design can also be selected for point-like or oval projections.
• a thickness of an upper side of the (strip-shaped) projection is preferably reduced. This creates a solidification of this section and the entire projection as such. This also applies to the process (claim 35).
• the score line can also be introduced at the same time as the post-forming, in the same operation (claim 51).
• the invention claimed here is covered the formation of the projection at such a location that is far enough from the intended fastening point (the formed rivet or its preform), and so far that the outer edge in the form of an edge of the attachment surface (rivet island ) comes very close to the projection to allow the turnstile to take effect.
• This space is in the outer edge area of a rivet head courtyard or the "rivet foot", which extends visibly around the formation of the rivet center from the preform of the rivet (claims 25 to 29, claims 46).
• the protrusion as a line or strip lies at least partially outside the weakened rivet base area in which the sheet is thin due to the shape of the attachment point.
• the edge region of this rivet foot is thus addressed (claim 26), preferably more than 40% of an assumed area of a strip-shaped projection lying outside the rivet foot region (claim 27).
• a strip shape is provided as a projection, its length can be made larger than the diameter of the finished rivet head.
• the attachment section is formed from a piece of the center area of the grip tab, there are only slight visible gaps between the attachment section, which is shifted downward by a double crease line into a lower level, and the parallel plane of the remaining grip tab, which is slightly above.
• the attachment of the projections to at least one of the free edge edges pointing outward from the attachment section is therefore difficult or impossible to see from the outside, so that the rotation block is almost invisible to the viewer. Any colored handle tab will not be changed in its colored design. Exemplary embodiments explain and supplement the invention.

• the handle tab 30 is essentially parallel to the panel, which itself does not have to be formed exactly in one plane, but can be slightly arched, but the area around the attachment point 11 is essentially flat and allows the attachment tab to be arranged essentially parallel 31 of the grip tab 30.
