Definitions

  • the invention relates to a rotary opener and closer for screws, screw closures on bottles and glasses and the like, with two converging side walls (2a, 2b) projecting vertically downward from the plane of rotation in the position of use, at the ends at which they are at their greatest distance are connected to each other by an approximately semicircular side wall (2c), a rough surface being provided on the side wall (s) for bearing against the edge of the workpiece (closure).
  • a rotary opener is known from US Pat. No. 3,760,657, the side walls of which converge in such a way that rotary closures with different diameters can be opened.
  • the rough surface is formed by teeth on one of the converging side walls.
  • the opposing converging sidewall and the semicircular sidewall are smooth so that the force applied by the operator to rotate the closure is proportional to one small area is transferred to the edge of the closure to be opened. This can lead to undesired deformation and damage to the closure.
  • the object of the invention is to create a rotary opener and closer of the type mentioned at the outset which enables screw closures with different diameters to be opened as securely as possible and thereby prevents damage to the screw closure.
  • This object is basically achieved in that the rough surface is formed on a spring steel band which rests against the inside of the side walls and is only attached to one side wall at one point.
  • the invention provides a tool which can be used both for opening and for closing by rotating the workpiece, for example a screw cap of bottles.
  • the tool only has side walls and no base plate connecting them, use as a rotary opener and a rotary closer is particularly good possible. Both when closing and when opening, the spring steel strip is always subjected to tension (see claim 2). To ensure that this tensile stress is ensured, the rotary opener or twist-off closer is placed on the workpiece, for example the screw closure, accordingly, ie in such a way that there is always a tensile stress.
  • the fastening is advantageously carried out as indicated in claim 3, so that the spring steel strip is always parallel to the side walls and is not rotated relative to these.
  • the rough surface is advantageously formed by a punched hole, as is known for example in kitchen graters.
  • the tool shown in the drawing is a rotary opener with a base plate 1 which forms the plane which, in the position of use, lies parallel to the screw closure to be opened (not shown). From the base plate 1, in the position of use, two converging side walls 2a and 2b extend downwards, which are connected to one another at the ends which are at a greater distance by a side wall (2c) which is approximately semicircular.
  • a spring steel strip 3 is fastened to the end of the side wall 2b.
  • the attachment point is designated 5.
  • This spring steel strip runs from the fastening point 5 along the side wall 2b over the side wall 2c to the end of the other converging side wall 2a opposite the fastening point 5. Due to the spring action, the spring steel band 3 clings tightly to the side walls.
  • sharp-edged punched holes 4 are provided in the manner of a kitchen grater, which form a roughened surface.
  • the direction of rotation that exists when a screw cap is opened is designated by R.
  • the direction in which the spring steel strip is stressed and possibly shifted is denoted by Z.
  • the rotary opener To open the rotary opener is placed on a lid of a glass or the like, so that the side walls 2a to 2d point downwards and the bottom plate 1 rests with its inside on the screw closure to be opened. Then the rotary opener is moved relative to the screw closure to be opened until the spring steel strip 3 comes to rest on both sides at the edge of the screw closure. Then the rotation takes place in the opening direction R, whereby the spring steel band attaches to both sides and detects the screw closure that is to be opened on both sides, so that a relatively large area is available in which the torque is transmitted. The load on the cover occurs over a relatively large area, so that damage to the cover is avoided. Due to the assignment of the fastening point 5 to the direction of rotation R, the spring steel strip is always subjected to tension when opening.
  • the end at which the two converging side walls 2a and 2b are at their smallest distance is dimensioned such that screw closures with small diameters, such as those provided on bottles, can also be opened here.
  • the base plate 1 is missing.
  • the side walls are designed to be correspondingly rigid, so that they do their job.
  • the tool is then placed on the opening so that the spring steel strip is subjected to tension. If the tool is then to be used for closing, it is rotated by 180 °, i.e. placed the other way around, so that the spring steel strip is again subjected to tension. It is hereby avoided in any case that the spring steel band forms an undesirable wave or loop.
  • the tool according to the invention allows screw caps on bottles or the like to be opened and closed in a particularly advantageous manner.
