Definitions

  • the invention relates to a method for producing a resealable container having an annular flange delimiting an opening and a foil-sealed closure membrane sealed against the flange and peelable from the flange, having a substantially annular first closure part connected to the closure membrane and a closure element with the container, substantially annular second closure member, wherein the first closure member and the second closure member are detachably connectable to each other and the closure membrane with the first closure member and the container with the second closure member form a reclosable unit.
  • containers such as deep drawn, injection molded or otherwise shaped container
  • containers such as deep drawn, injection molded or otherwise shaped container
  • 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 packs, etc. are known, for example, for packaging food of all kinds, e.g.
  • Dairy products in particular yoghurt, whipped cream, sour milk, sour cream, creamer, ready-made preparations of salads or semi- or canned goods, precooked or otherwise prepared dishes, beverages, such as fruit and vegetable juices or drinking water.
  • a separate plastic lid in particular transparent plastic, is provided for reclosability of these packages in some cases, which is slipped over the closure membrane and forms a detachable latching connection with the cup rim.
  • a disadvantage of the known packaging is that the additionally provided lid must be manufactured as a separate component and provided on the packaging. This significantly increases the weight as well as the manufacturing and assembly costs of the packaging.
  • the extra lid provided in these packages is only connected via a releasable latching connection with the cup, so that there is a risk that the lid dissolves during transport from the packer to the dealer from the cup and is lost.
  • Out DE 10 2008 034 493 A1 is a reclosable container of the type mentioned above with an opening bounding, annular flange and sealed against the flange, the opening closing and peelable from the flange, foil-shaped closure membrane known.
  • a substantially annular first closure member is connected to the closure membrane and a substantially annular second closure member to the container, wherein the first closure member and the second closure member form a releasable latching connection and the closure membrane with the first closure member and the container with the second closure member a resealable Form unity.
  • the first and the second closure part are connected to one another via a predetermined breaking point.
  • the sealing membrane is sealed onto the interconnected closure parts.
  • the unit consisting of the two closure parts with sealed closure membrane is connected to the cup.
  • the invention has for its object to provide a method by which a reclosable container of the type mentioned can be easily and inexpensively manufactured on standard processing machines.
  • the first closure part connected to the closure membrane and the cup with the second closure part is made as part of the cup, the closure membrane is placed with the first closure part on the flange of the cup and peelably sealed against the flange, wherein the first closure part with the second closure part is releasably connected, and wherein the adhesive force between the first closure part and the closure membrane is greater than the adhesive force between the closure membrane and the flange, so that the first closure member connected to the closure membrane releasably upon initial and each further opening of the cup by pulling the closure membrane from the flange of the second closure member and when laying the closure membrane on the flange the second closure part is connectable.
  • circuit boards can be used as sealing membranes.
  • the first closure part is preferably a part produced by injection molding and can be connected to the closure membrane by gluing or sealing.
  • the first closure part is produced by injection molding in the in-mold process and connected to the closure membrane.
  • a material is selected which ensures a firm connection between the closure part and the closure membrane.
  • a suitable material is a thermoplastic, in particular polyethylene (PE) or polypropylene (PP).
  • the first closure part preferably has a base ring with clamping elements protruding therefrom, and the second closure part is expediently formed by undercuts in a side wall of the container.
  • the clamping elements can be arranged distributed individually over the circumference of the base ring.
  • the base ring may have wedge-shaped cuts or breaks to provide greater flexibility.
  • the ring remains so flexible at the opening of the sealing membrane that the sealing membrane with the usual peel force can be pulled from the container.
  • the undercuts or depressions in the side wall of the container are conveniently formed during deep drawing or injection molding of the cup.
  • the closure membranes can be deep drawn or embossed to increase their number in a stack.
  • 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 monofilms or multilayer laminates. Other lidding materials may be cellulosic materials such as cellophane or paper. Also used are laminates of metal and plastic films.
  • the lid material is usually provided over the entire surface with a sealing layer, such as a sealing wax, a sealable extrusion layer or a sealing foil, wherein the sealing layer on the inwardly facing side of the finished package, i. pointing towards the container interior, is arranged.
  • a sealing layer such as a sealing wax, a sealable extrusion layer or a sealing foil, wherein the sealing layer on the inwardly facing side of the finished package, i. pointing towards the container interior, is arranged.
  • ring-shaped or partially applied sealing layers are also possible.
  • the containers are usually formed of plastic by deep drawing or injection molding. Suitable containers can also be painted by deep-drawing or extrusion-coated films made of metal or metal / plastic laminates.
  • FIG. 1 illustrated container 10 according to the prior art in the form of a cup made of plastic for receiving, for example, yogurt has a bottom 12 and a towering from this, a Gregutvolumen limiting side wall 14. From the bottom 12, the side wall 14 extends, in the example shown with an outwardly directed angle of inclination, upwards and goes at its bottom distal end in a horizontally outwardly projecting, annular flange 16 via. The transition from the side wall 14 into the annular flange 16 delimits a container opening 18. The free end of the flange 16 forms a cup rim 20.
  • a foil-like circuit board or closure membrane 22 which seals the container opening 18 tightly and can be peeled off from the flange 16 sealed.
  • the sealing takes place with a sealing tool with an annular or full-area stamp and leads to an annular, bounded by an inner ring edge 24 and an outer ring edge 26, common annular connecting surface 28 between flange 16 and sealing membrane 22.
  • the limited by a membrane edge 21 sealing membrane 22 has at one point on the cup rim 20 superior tear strip 23.
  • the sealing membrane 22 on the against the inside of the container 10 directed side with an annular first closure member 30 and on the inside of the side wall 14 of the container 10 with a second closure member 32 in the form of a arranged in the side wall 14, circumferential groove or undercut 33.
  • the first closure part 30 is equipped with regularly distributed over the circumference of a base ring 34 and projecting from this clamping or snap elements 36.
  • the sealing membrane 22 is separated from the flange 16 by peeling.
  • the clamping elements 36 thereby overcome the retaining force of the groove or undercut 33.
  • the sealing membrane 22 is placed back on the flange 16 and the clamping elements 36 snap again. Due to the large number of clamping elements 36 only slight undercuts are required on the cup 10 in order to achieve a "snap effect".
  • clamping elements 36 are arranged on the base ring 34 of the first closure part 30. This facilitates peeling when it is first opened.
  • the side wall 14 of the cup 10 slightly inclined to the container bottom 12 and arranged in the side wall 14 as recesses guides 40 are provided for a rotary closure.
  • the sealing membrane 22 is slightly rotated after placing on the flange 16, so that the clamping elements 36 run into the guides 40 and lead to a "fail safe" reclosure.
  • the flange 16 is formed on the pull-tab 23 opposite side as a downwardly inclined cup tab 17.
  • the snap or clamping elements 36 are partially recessed in the tear tab 23 and on the opposite side.
  • the base ring 34 is reduced in this area to a transverse web 42. This results on the one hand a lighter opening on the side of the tear tab 23 and the closure membrane 22 remains open after opening by its own weight.
  • the crossbar 42 stabilizes the sealing membrane 22 after the opening of the cup 10.
  • the clamping system for rectangular and other shapes, such. As oval and polygonal shapes, suitable.
  • the base ring 34 is provided with laterally projecting from this annular clamping elements 36 in order to achieve a lower stack height.
  • a sealing membrane 22 is the base ring 34 - as in Fig. 10 - Equipped with laterally projecting from this annular clamping elements 36.
  • the sealing membrane 22 is deep-drawn or embossed.
  • the side wall 14 of the cup 10 is provided with a parallel to the flange 16 extending step 44.
  • the first closure part 30 has a base ring 34, from which clamping elements 36 protrude laterally outward and engage in depressions 46 in the side wall 14 of the container when reclosing the container 10. Between the clamping elements 36, the base ring 34 interruptions 35. These increase the flexibility of the base ring 34 and facilitate peeling the closure membrane 22 during opening.
