Definitions

  • the invention relates to a method for reconditioning a container by separating the components at the site of the seam between body and lid, and bottom respectively, cleaning and reshaping them, and subsequently rejoining them, if desired.
  • Such a method is generally known in the art and is applied in various ways.
  • This object is achieved according to the present invention by the fact that with a folded seam having sheet edges which are coiled around one another in the form of a spiral in section, the folded seam is entirely or for the greater part unfolded, i.e. uncoiled, by axially supporting the container at the site of its bottom and lid respectively, by giving full radial support to the inner edge of the lid and bottom respectively, and by moving an apparatus over the folded seam and right along the entire circumference of the body of the container in an axial direction towards the supporting means. It is understood that this relative displacement can be effected by displacing the supporting means while keeping the apparatus stationary, or by keeping the supporting means with the container stationary while displacing the apparatus.
  • the apparatus preferably consists of a ring and said ring is preferably made in a number of radially movable segments.
  • the spiral folded seam can be entirely uncoiled without any fractures occurring, and that after the cleaning of and the repairs to body and lid, and respectively bottom of the container has been effected, both components can be joined together again by means of a spiral folded seam and, which is even more surprising, that this operation can be repeated several times without any detrimental effects.
  • the invention also relates to an apparatus for carrying out the method of the invention.
  • This apparatus consists of a supporting means for the bottom or lid of the container, which supporting means has radially expandable segments, which serve to restore the original circular shape to the edge of the container, while the apparatus moreover comprises the ring, previously indicated, and the radially inwardly movable segments forming said ring, respectively, said supporting means, which supporting means and ring are axially movable with respect to one another, the structure being preferably embodied such that the supporting means is movable and the ring is stationary.
  • the device cooperating with the supporting means consist of one or more rollers taking the place of the ring, the center line of said rollers being in radial extension to the center line of the container.
  • the center line of said rollers being in radial extension to the center line of the container.
  • FIG. 1 shows a side view and sectional view respectively of the preferred embodiment of method and apparatus according to the invention.
  • FIGS. 2,3,4 show a part of FIG. 1 showing the method according to the invention in various stages.
  • FIG. 1 shows a container 1 with lid 2 and bottom 3.
  • the container 1 is positioned with its bottom 3 on a supporting means 4, which fits therein with a close fit, and is provided with radially expandable segments, not shown, respectively.
  • the segments 5 and the supporting means 4 are displaced in a relative axial direction with respect to one another, preferably by displacing the supporting means 4 in the direction of the arrow 7.
  • FIG. 2 shows the initial stage and FIG. 3 shows the final stage, while FIG. 4 shows an intermediary stage which, in many instances however, may be regarded as the final stage, since in this position of the uncoiled sheet edges the components can be taken apart as well.
  • the components can be put together again, which may be effected in a way known as such. If subsequently the method described in the Dutch patent application 70.09657 is again applied, the uncoiling can be repeated in accordance with the method of the invention.
