Definitions

  • the invention relates to a closure lid for sterilizable cans with a flange edge intended for flange fastening with the edge of a can body made of sheet metal provided with a corrosion layer and with a membrane part connected to a lid by means of a predetermined separation area and having a tear-open flap.
  • a closure lid of this type is used in the well-known tin cans of the so-called easy-open type.
  • the flared connection between the flanged edge of the prefabricated sealing cover and the can body is made when the filled can is closed.
  • the resulting flare shape is shown, for example, in DE-OS 2 114 154.
  • the predetermined separation area of this known sealing cover according to DE-OS 2 114 154 is formed by a notch line embossed from the upper side of the cover.
  • the membrane part of the lid spans the can opening like a membrane and carries a riveted finger grip for tearing off along the predetermined separation area.
  • a sealing material is applied to the cover along this line.
  • the flanged edge can be provided with a rubber layer, so that a vacuum-tight flared connection is guaranteed.
  • Fastening the closure lid on the edge of the can body has the advantage that the tightness of the connection cannot be impaired by filler material that may be adhering in this area.
  • the thickness of the sheet material used is selected so that sufficient clamping forces remain in the flared connection after the flanging.
  • the flare connection also has the advantage that the edge of the closed box is stiffened accordingly by the multilayer structure that results there.
  • a can sealed with such a sealing lid has sufficient tightness and temperature resistance in order to be able to sterilize its container contents under the high temperature influence of approx. 130 ° C.
  • the cap also has an adequate one Tightness for vacuum packaging.
  • a disadvantage is the additional sealing required by means of a rubber layer along the predetermined dividing line.
  • the creation of the target dividing line in a sheet material having a corrosion protection layer by notches also leads to the destruction of this layer along the target dividing line and thus to the possibility of corrosion when stored in a moist environment.
  • the invention is based on the object of avoiding the disadvantages mentioned and utilizing the described advantages of such a closure cover in such a way that it can be produced with less material and without additional expenditure for the sealing of its predetermined separation area.
  • the closure cover should be easy to open with a simple construction with little effort. This object is achieved on the basis of the characterizing features of patent claim 1.
  • the dependent claims relate to advantageous embodiments of the invention.
  • a closure lid with a peripheral fastening ring formed from sheet metal and a membrane part sealed with this is known per se from CH-PS 475.136 or CH-PS 565.079, however, such a closure lid is not suitable for sterilizable cans and is used before the can is filled on Can body attached.
  • the can is filled from below and a bottom lid is used to close it.
  • the membrane part I which is made of relatively thin film material, is connected to the fastening ring by a sealing connection that is not resistant to sterilization temperature and must be protected by an additional can lid.
  • the edge of the lid is designed to be clamped to a box body made of cardboard.
  • Cans provided with such a closure lid are known for packaging dry, powdery material, such as coffee powder, but are not suitable as so-called cans.
  • the radially inner circumferential cutting edge of the fastening ring of such a known closure lid which has no corrosion layer, is also either the can turned towards the inside and comes into contact with the filling material or has turned outwards so that it is exposed to external corrosive effects, eg due to a damp atmosphere.
  • a corrosive attack beginning at the cutting edge can continue up to the sealing connection and cause it to detach.
  • a corrosive attack on an outward cutting edge is also unacceptable for aesthetic reasons, so that the filled can cannot be sold, even if the corrosive attack does not lead to a leak.
  • the closure cover has a peripheral fastening ring 2 and a membrane part 4.
  • the membrane part 4 is shown at a distance from it before it is sealed to the fastening ring.
  • the fastening ring 2 has a flanged edge 6 which is pre-bent for producing a flanged connection with a socket body (not shown) and which corresponds to the stacking of a plurality of closure lids the illustration in Fig. 7 enables leicnt conical wall part 7 of the fastening ring. In its lower region, this wall part 7 merges into a radially directed ring part 8, the upper side of which serves as a support and seal connection with the membrane part 4.
  • the fastening ring was punched out in a ring shape from a sheet of metal provided with a corrosion protection layer on both sides and deep-drawn or embossed in a shape as shown in FIG. 1.
  • the radially inner edge region 10 with the radially inner cutting edge 11 was bent back in itself and towards the top of the cover.
  • the bending shape used in the example according to FIGS. 1, 2 is approximately circular in cross section, so that the container opening 13 formed by the sealing cover and closed by the membrane part 4 is delimited by a correspondingly shaped bead.
  • the membrane part 4 When the membrane part 4 is sealed onto the radially directed ring part 8, the already pre-bent radially inner edge region 10 is bent into the shape shown in FIG. 2 by the heat sealing stamp 14.
  • a lower molding 15 absorbs the pressure of the heat seal stamp.
  • the membrane part 4 is heat-sealed at two radially circumferential sealing regions 17, 18 which are spaced apart from one another and are separated from one another by a gap 19 which is located between the top of this radially inner edge region 10 and the region adjoining radially outwards of the radially directed ring part 8 results.
  • the upper side of this edge region 10 is preferably arranged in one plane with the upper side of the ring region adjoining radially outwards, but the sealing region could also bridge a gradation between the two, since the membrane part can easily adapt to different shapes.
  • the embodiments of the closure cover according to the representations of FIGS. 3 and 4 differ only in the cross-sectional shape of the radially bent backwards radially outward inner edge area 10 ', 10 ".
  • the edge area bent radially outward has a flat surface 20, 21 lying in a radial plane for the production of a correspondingly wide sealing area.
  • the radially directed ring part 8 has a gradation corresponding to the sheet thickness 23, 24 so that the radially outwardly adjoining surface area 25, 26 lies in the same plane with this surface 20, 21.
  • a tear-open tab 33 is formed on a circumferential point of the membrane part 4, so that the membrane part 4 can be peeled off from the sealing area by pulling on this tear-open tab, so that the sealing area on the surfaces 20, 25 and 21, 26 forms the desired separation area of the sealing cover.
  • the sealing connection is made by means of a heat sealing lacquer provided on the surfaces to be connected with one another with sufficient temperature resistance so that the sealing cover and its sealing connection can withstand the temperatures of approximately 130 ° C. which occur during sterilization.
  • the sealed connection can also be referred to as a welded connection. It goes without saying that the sealed or welded connection must not be stronger than the tensile strength of the membrane part 4, but the peeling movement when pulling on the tear-open tab allows detachment with relatively little effort.
  • a gradation 50 is provided in the approximately cylindrical part 7 "of the fastening ring, comparable to the exemplary embodiment according to FIG. 4.
  • the lower end 52 of the folded-over part of the fastening ring In this embodiment according to FIG. 6, 36 is bent slightly inward in an arc shape to adapt to the curve 53 in the transition region between the approximately cylindrical membrane part 54 and the membrane part 55 spanning the opening 42 and lying in a radial plane.
  • Fig. 8 shows a closure cover 1 according to the invention e.g. according to the embodiment of FIG. 3, in which the membrane part 4 is provided with a slight bulge upwards.
  • the membrane part bulges inwards in a corresponding form due to the external pressure caused by the vacuum, so that lower loads occur on the membrane part I.
  • the bulge inwards is also an indication that there is a vacuum inside the can.
  • the membrane part can, as indicated by the cross-sectional view in FIGS. 1 and 2, be provided with a fine profile 57, which leads to a higher load capacity of the membrane part.
  • This fine profiling is, for example, waffle-shaped or consists of numerous small bulges arranged next to one another.
  • the shape of the lid in supervision which cannot be seen in the drawings, can be selected differently, e.g. circular, oval, rectangular with rounded corners, etc.
