Definitions

  • the invention relates to a container having an opening bounding, outwardly projecting, limited by a cup rim, annular flange and to form a common, annular, bounded by an inner edge of the ring and an outer ring edge connecting surface against the flange marlegelten, the opening closing and Peelable from the flange, follenförmigen, bounded by a membrane edge closure membrane with a tearing over the edge of the cup tear-open.
  • containers such as deep-drawn, injection-molded or otherwise shaped containers, at its opening with a flat, annular flange and such containers, especially after filling, to cover, the lid or the sealing membrane over the entire surface rests on the flange and is peelably and sealingly attached, for example by sealing or gluing the flange.
  • Such containers, trays, meal trays, for example with one or more compartments, cups, small packages, etc. are known, for example, for packaging food of all kinds, e.g. Milled products, in particular yoghurt, whipped cream. Sour milk, sour cream, coffee cream, Ferdgzururgi of salads or half or full canned food, pre-cooked or otherwise prepared dishes, drinks, such as fruit and vegetable juices or drinking water.
  • the lids, sinkers or sealing membranes are exemplarily punched out of an endlessly present, sheet-shaped lid material and stacked.
  • the lid stacks are fed to a packaging machine and the isolated or unstacked, provided with a sieve layer lid are sealed by means of a Slegeltechnik Wegss in the flange portion of the container on the container edge of the already filled container.
  • the lids are often embossed or provided with Abstandhaltem when they are processed from magazines. Alternatively, the lidding film of the Roll are processed and stamped together after sealing with the cup.
  • the lid material is sealed flush with the cup rim, and the lid is typically mounted on a tear tab.
  • the lid should peel away from the sealing flange without it breaking in, thereby preventing the container from opening completely.
  • the tensile force acts particularly strong on opening the lid on the edge of the lid, so that the lid no longer peels from the cup, but einreisst.
  • Particularly high is the tearing tendency at the beginning of the tearing process, since the lid edge here requires very little force for reloading. As the opening progresses, the risk of tearing decreases more and more.
  • the Einrelssen of lids or sealing membranes at the opening is a nuisance for the consumer.
  • the Einrelssen prevents further thinning of the lid material, as this Einrelssen would occur even more because of the lower Einrelsskraft.
  • a relatively strong seal e.g. over 8 N / 15 mm
  • the typical flush sealing lid cover with the outer edge of the cup wear particularly strong to tearing bel, since the lid foil is torn off virtually from the sealing edge.
  • relatively low tearing or tear resistance of the lid materials acts directly on the edge of the lid.
  • the tearing of the lid material can be prevented by increasing the material thickness or by laminating with tear-resistant follicles. Both solutions increase the costs considerably.
  • cover rings for flaring on cans that the sealed onto the cover ring sealing film to prevent the tearing of the film edge during the peeling process in one embodiment has a over the entire outer edge of the film reaching beyond its attachment area also protruding Rendstrelfen.
  • the VerInstitutfolle on both sides of the grip tab on the attachment area outwardly projecting "ears" on.
  • the invention has for its object to design in a container of the type mentioned, the connection of the sealing membrane with the container so that bel only slightly higher material use opening without Einrelssen the membrane is possible.
  • the sealing membrane projects freely beyond the outer ring edge of the veneering surface from the tear-open tab and the distance of the membrane edge from the tear-off tab to the outer ring edge is opposite to a diameter line extending in a tear direction on both sides of the tear-open tab to an angle of at least every 45 ° decreases steadily to zero.
  • the distance of the membrane edge to the outer ring edge of the connection surface decreases steadily to an angle of approximately 90 ° to zero.
  • the breakage level can also be reduced by reducing the area of connection between the flange and the closure membrane in the region of the pull-tab, e.g. through a narrower design, is reduced. In practice, this can be achieved for example by a corresponding gradation in the flange.
  • the common annular interface is concentric with the cup rim and the outer annular edge of the interface is substantially congruent with the cup rim.
  • a projection of the closure membrane over the edge of the cup results in the region of a first flange half. If necessary, this projection can be avoided by means of a flange or cup edge which is eccentrically shaped in this area.
  • the common annular interface is arranged eccentrically to the annular flange on the diameter line extending from the tear tab in the tearing direction about a flyback directed away from the tear tab, and the edge of the closure membrane is substantially congruent with the cup rim except for the tear tab.
  • the flange or the cup rim can be eccentrically shaped.
  • the lid material can consist of a wide variety of materials. Typical examples are metal foils coated on one or both sides with plastic. Other lid materials contain or consist of plastics in the form of monolayers or multilayer laminates. Further cover materials may be made of cellulose-containing materials, such as line glass or paper. Also used are laminates of metal and plastic films.
  • the lid material is usually voilflächig with a sealing layer, such as a sealing wax, a sealable extrusion layer or a Sealing film provided, wherein the sealing layer on the on the finished packaging inwardly facing side, that is facing away from the container interior, is arranged.
  • a sealing layer such as a sealing wax, a sealable extrusion layer or a Sealing film provided, wherein the sealing layer on the on the finished packaging inwardly facing side, that is facing away from the container interior, is arranged.
  • ring-shaped or partially applied sealing slaves are also possible.
  • the containers are usually molded from plastic by deep drawing or injection molding. Suitable containers can also be made by deep drawing of lacquered or extrusion coated films of metal or of metal / plastic laminates.
  • FIG. 1 illustrated container 10 in the form of a cup made of plastic for receiving, for example, yogurt has a bottom 12 and a towering from this, a product volume limiting side wall 14. From the bottom 12, the side wall 14 extends, in the example shown with an outward inclination angle, upwards and goes at its bottom distal end in a horizontally outwardly projecting, annular flange 16 over. The transition from the rare wall 14 in the annular flange 16 defines a container opening 18. The free end of the flange 16 forms a cup rim 20. against the annular flange 16 is a the container opening 18 tightly closing and peelable from the flange 16, follenförmige board or sealing membrane 22nd sealed.
  • Slewing is carried out with a sealing tool with an annular or full-area punch and leads to an annular, bounded by an inner ring edge 24 and an outer ring edge 26, common annular connecting surface 28 between the flange 16 and sealing membrane 22, which has a membrane edge 21 limited sealing membrane 22 at one point on the cup rim 20 superior tear strip 23.
  • the seal is carried out so that the common annular connection surface 28 between the flange 16 and sealing membrane 22 is arranged concentrically to the flange 16 and the outer annular edge 26 of the annular connection surface 28 is substantially congruent with the cup rim 20 ,
  • the sealing membrane protrudes beyond the outer annular edge 26 of the annular connection surface 28 and thus beyond the cup rim 20, wherein the distance between the edge 21 of the closure membrane 22 and the cup rim 20 on both sides of the tear tab 23 over a first flange half up to an angle of both sides of each 90 ° to a tear direction x defining fürmesserilnle steadily decreases to zero.
  • the membrane edge 21 should at least up to a two-sided angle of protrude about 45 ° above the cup rim 20.
  • the closure membrane 22 which is congruent with the cup rim 20 protrudes beyond the outer annular wall 26 of the annular connection surface 28, the distance between the edge 21 of the closure membrane 22 and the outer annular edge 26 of the annular connection surface 28 beldselts the tear-open tab 23 over the first Flange half decreases steadily to zero at an angle of beldselts at 90 ° to the diameter direction defining the tearing direction x.
  • About the subsequent second flange half of the membrane edge 21 extends substantially congruent with the cup rim 20 and the outer annular edge 26 of the annular connecting surface 28.
  • the membrane edge 21 should also at least in this variant up to a two-sided angle of about 45 ° beyond the outer annular edge 26 of the annular connecting surface 28 protrude.
  • closure membranes shown in the drawing have a circular shape corresponding to the cups with a circular opening.
  • the invention is not limited to these examples, but also includes other geometric container openings and lid shapes, such. B. oval and polygonal shapes.
