Definitions

  • the invention relates to a device for connecting at least two container parts to a container, wherein the device has a die and a hold-down and is provided with a cutting punch and a sealing die, the cutting punch movable in the hold and thereby out of the hold-down and into the Matrix is movable into it.
  • a container which is made of plastic and / or metal, in particular of films, which consists of these materials.
  • the two container parts usually form a receiving body and this closing cover sheet.
  • a cover sheet is placed on the receptacle, which has a cavity or depression accommodating the product, which is placed on the
  • cover film is previously punched out of a film composite. It is also known that the cover sheet is sealed to the deep-drawn, filled, located in the composite film cups and in a second step, the sealed cups are separated.
  • the distance between the crown punch and the inner sealing element, wherein the seal is based either on heat or ultrasound, results in a non-sealed area between the separating edge of the cover foil and the outer edge of the sealing edge, which can be both visually and functionally disturbing.
  • a device is known with which a container can be closed.
  • a lid is punched out of a film web, which is then welded by means of an ultrasonic sonotrode on the edge of a receptacle. It has been found that the lid is outside the desired welding area, i. in the lid surface surrounded by the welding rim, is also heated, which is often unintentional, since distorted by the heating of the lid or even melt, since the lid is not supported in this lid surface of the material of the receptacle.
