Definitions

  • the invention relates to insert lids according to the preamble of the claim 1, on cans with it and on a method for producing such Insert lid.
  • plug-in lids have so far either been made of plastic and have a radially outward-facing stop that is in the inserted state is supported on the open edge of the can, e.g. B. according to US-A-4,088,242; they are problematic due to disposal.
  • the common cardboard cans are mostly used as packaging, which are removed after their intended use.
  • the Cans and lids made from one and the same, easily recyclable material be trained. So that means that end floors and lids should be made of cardboard and / or strong paper.
  • end floors and lids should be made of cardboard and / or strong paper.
  • foods are suitable, such as cardboard boxes and Cardboard lid with metal, especially aluminum, but possibly also used with plastic layers.
  • a well-known insert lid includes a flat end surface made of semi-cardboard or solid Paper placed at its circular edge in a cylindrical contact area transforms. The end surface with the cylindrical contact area is produced from flat flat material by a punching and pressing process. At the free or open end of the contact area there is half inside folded cardboard cylinder section placed and glued to it attached.
  • the folded cardboard cylinder section encloses a partial area of the contact area and forms the Grip rib and on its outer edge that on the edge of the can opening attachable stop area.
  • the contiguous contact areas of the lid and the box must be dimensioned so that the Cover can be inserted or removed even with different air humidity levels is.
  • When inserting a cover its scope of contact area
  • the lid can be irreversible somewhat above the circumference of the socket contact area be deformed by wrinkles in the contact area and in particular also form in the end area.
  • the outer surface of the lid should be approx moisture-resistant coating. For material-related reasons of tolerance can not rule out the mentioned wrinkling become.
  • Plug-in lids have also been proposed which consist of 3 or more Cardboard parts are made, e.g. according to US-A-2'638'820, or one on the can jacket hanging plug-in lid form (EP-A1-668'151) by according the insertion of the end face of the can jacket along a circumferential -
  • a broken tear line - is broken open, which, however, the formation of a spanning the can edge Membrane impossible.
  • both are proportionate cumbersome training, the production of which is relatively expensive.
  • the invention has now set itself the task of forming a plug-in lid, who does not have the problems mentioned, and its contact area preferably always close to an annular area of the inner surface of the can jacket.
  • the contact area can be pressed against the inside of the can jacket and therefore not inserted Condition little larger than the can opening should.
  • the largest circumferential line should appear of the contact area through an elastic deformation of the end surface adjust to the inside of the can jacket. So that when plugging in forces from the can jacket do not lead to irreversible deformation lead, the end face must be radial to the contact area spring properties have an elastic deformation of the contact area enable in the radial direction. To ensure these spring properties the end surface has a surface that deviates from a flat surface Shape up.
  • Lids according to the invention can be used both for cans with circular openings as well as for cans with differently shaped openings, especially for Rectangular or hexagonal openings, especially with rounded ones Corner areas.
  • the waves are also preferred circular and arranged concentrically.
  • the preferred ones are with circumferential lines approximated to polygons Waves in a range from polygon to circular lines.
  • Preferred Embodiments achieve the desired spring property the use of two side by side at substantially constant intervals waves running to the contact area.
  • a heat seal connection For connecting the cardboard cylinder section with the contact area is a heat seal connection, preferably in a manner known per se by means of heatable expansion wedges or the like, but possibly also a glue connection or a roll connection educated.
  • glue applied to the points to be joined when performing the End surface can be stripped through the cardboard cylinder section.
  • the pressed parts with a convex pressing surface are from a feed position with a smaller pressing surface circumference movable in a press position with a larger circumference.
  • the Pressed parts can be dimensioned in such a way that they lie one against the other form paragraph-free, closed circumference.
  • Fig. 1 shows a plug-in lid 1 made of cardboard, semi-cardboard or solid paper for a box 2.
  • the insert lid 1 consists of an end surface 3, which extends over the cross section of a can opening 4 and in its Outside area over a curvature of essentially 90 ° into a contact area 5 passes.
  • the first end region 6a has the same Opening cross section like the can 2 which can be closed with the lid 1, so that this first end region 6a when inserting the cover as at the The stop area that can be created can act.
  • the second end area 6b of the cardboard cylinder section 6 is to form a grip rib on the inside folded or rolled.
  • the connection is of the contact area 5 with the cardboard cylinder section 6 as a seal connection executed. It would also be possible to use this connection as a rolling connection to train.
  • the end face 3 In the end face 3 are two circular, concentrically arranged Waves 7, and a central, possibly against the end area with the dome-shaped curvature 8 directed towards the grip rib.
  • the two shafts 7 run in the outer edge region of the end face 3, the distance between the outermost ones Wave from the contact area corresponds essentially to the wave width.
  • the waves 7 and the curvature 8 are so pronounced that the contact area 5 directly after the transition from the end face 3 to the contact area 5 little about the opening edge 4 one to be closed Can 2 protrudes.
  • this protruding area pressed inwards; the waves 7 and the curvature 8 become something increasingly trained and produce - in the sense of a compressed Spring - a restoring force that the contact area against the inside of the can jacket.
  • Fig. 2 shows the concentric shafts 7, Fig. 3 that when inserted Cover 3 tensioned shafts 7 and the slightly raised curvature 8.
  • Fig. 4 shows an end surface 3 with a conical contact area 5 at Insert into a cardboard cylinder section 6, Fig. 5 after sealing with the cardboard cylinder section 6.
  • the free end of the cardboard cylinder section is then turned or rolled inwards.
  • the cardboard cylinder section 6 is preferably cut from the same tube as that Can jacket and can be wound spirally or in parallel.
  • FIG. 6a shows shafts 7a formed upwards, FIG. 6b downwards Shafts 7b, and Fig. 6c a combination of up and down trained shafts 7a and 7b. It goes without saying that the most varied Waveforms and combinations of waves can be used are, provided that they make the desired spring effect achievable.
  • FIG. 7 shows the standard embodiment of the invention in a somewhat enlarged representation, with an end surface 3 ', the vertical edge region 5' of a cardboard cylinder section 6 is included, the upper edge for training a grip rib (this in an analogous manner as shown in Fig. 1) is crimped inwards.
