Definitions

  • Container-closing apparatus for carrying out the above method includes a shock current induction coil having a singlelayer spiral winding disposed in a given plane, a punch die having an opening with a profile corresponding to an opening of the container that is to be closed, the punch die being disposed in a plane underlying and spaced from said given plane a given distance so as to provide clearance for the insertion of a metal band therebetween, and means for inserting the container in the opening of the punch die.
  • Our invention relates to method and apparatus for closing containers, such as bottles, for example, with closures similar to bottle caps.
  • Our invention is based on the fact that electric currents are induced in metals by rapidly varying magnetic fields and, due to the interaction of the alternately flowing current with the varying magnetic fields, deforming shock waves are produced in a surrounding medium such as air and Water or the like.
  • a surrounding medium such as air and Water or the like.
  • shock wave forces for fluidtightly or liquid-tightly closing containers such as bottles with closures similar to bottle caps.
  • a shock current induction coil having a single-layer spiral winding disposed in a given plane
  • a punch die having an opening with a profile corresponding to an opening of the container that is to be closed, said punch die being disposed in a plane underlying and spaced from said given plane a given distance so as to provide clearance for the insertion of a metal band therebetween, and means for inserting the container in said opening of said punch die.
  • FIG. 1 is an elevational view, partly in section of the apparatus of the invention.
  • FIG. 2 is a top plan view of the punch die forming part of the apparatus of FIG. 1.
  • FIG. 1 only those parts of the container-closing apparatus that are essential for comprehending the invention of this application.
  • a punch die 1 is provided, extending in a given plane, and a shock current coil 2 having a single-layer spiral winding is located in a plane thereabove, as shown in FIG. 1, and spaced a given distance therefrom.
  • the spacing between the coil 2 and the punch die 1 is of such dimension as to provide clearance for the passage of a metal band 4 therebetween.
  • the metal band 4 lies on top of the punch die 1, as shown in FIG. 1 and is engaged by the mouth of the bottle 3 or other container which is to be closed.
  • the cleaned and filled bottle 3 or other container is moved upwardly, as shown in FIG. 1 by conventional means such as the illustrated clamp 7, so that the opening thereof extends into the die opening which has a scalloped profile.
  • a shock current of relatively short duration is supplied to the coil 2 through the leads 5 and 6 thereof by a conventional non-illustrated shock current source, thereby producing a rapidly varying magnetic field at the location of the metal band 4.
  • This magnetic field induces electrical currents in the metal band 4 which interact with the magnetic field to produce a pressure wave or force which causes a bottle-cap blank, of shape and size determined by the shape and size of the die opening, to be punched out of the metal band 4.
  • the ring-shaped zone which is formed between the edge of the die defining the die opening and the neck of the bottle 3 is of such dimension that the scalloped edge of the cap blank is pressed around the annular head at the mouth of the bottle 3 so that the fully formed cap is firmly secured thereon and tightly closes the opening of the bottle.
  • the closed bottle 3 is thereafter removed from the die opening by actuating suitable conventional mechanism which, for example, moves the clamp 7 in a downward direction, as viewed in FIG.
  • the bottle is then carried away to another location at which it may be further processed.
  • the metal band is simultaneously advanced so that an unbroken surface thereof overlies the die opening.
  • ignition pulse can be applied simultaneously to the aforementioned non-illustrated shock current source through a delay line so that the entire container-closing operation can be completed rhythmically with a single pulse. In this way, the greatest possible production of closed containers can be achieved.
  • the metal band 4, when desirable, may be provided with a layer of sealing or packing material, such as a suitable plastic material, which adds to the sealing effect of the cap blank punched from the metal band 4.
  • the packing material may be coated on the metal band 4 directly or may be in the form of a loose foil strip interposed between the metal band 4 and the die 1 and can be supplied from a non-illustrated roll thereof.
  • the layer of packing material serves as a protection for the container or bottle against being struck directly by the metallic cap blank punched from the metal band-4.
  • the dimensions of the individual bottle openings can vary without producing any danger that the cap or closure will have a liquid-tight fit. Moreover, maintenance of a large stock of different types of caps or closures is thereby obviated.
  • the heretofore practice of separately fabricating the caps and then transporting them to the location at which they are pressed onto the container is now dispensed with because, in accordance with our invention, the metal band 4, of which the caps are formed, can be located on spools within the container-closing machine proper. Also, hygienic requirements can be better met for a metal band, as in the invention of this application, than for completed container closure which must be stored and then transported to the location at which the containers are closed.
  • all types of containers with beaded edges about the openings thereof can be closed, even when the openings are rectangular, for example.
  • the material of which the container is made is furthermore inconsequential.
  • the closure can also be pressed over a shaped component which is similar to the beaded edge.
  • the edge is flanged, for example, or in the case of a cylindrical metal container, is expanded or widened so that the cross section thereof is provided with a trapeziform profile.
  • Method according to claim 1 which includes coating one side of the metal band with packing material so as to seal the closed opening of the container.
  • Method according to claim 1 which includes inserting packing material in the form of a foil strip between the metal band and the container opening and simultaneously punching a blank from the metal band and from the packing material and pressing them on the container.
