Definitions
- the invention relates to a cover according to the preamble of claim 1.
- Lids for disposable containers are known.
- the lids should also meet another requirement if possible: they should be easy to open without the risk of parts of the contents of the filled disposable container splashing when opened.
- the opening is a special problem because the lid has to seal this disposable container tightly by flanging it on the circumferential flange edge of the disposable container.
- DE-A 2454645 which shows a lid of the type mentioned at the outset
- DE-A 2140733 to provide tear-open tabs on the lid, possibly in combination with prepared tear lines
- torn-open lid parts roll up like a spring due to the inherent tension and in the process splash food parts adhering to them when detached from the container.
- the removal of the other lid parts still remaining on the container is also very laborious, and there is even a risk of injury to the sharp tear edges.
- the object of the present invention is therefore to design the lid of the type mentioned at the outset in such a way that it can be removed from the closed disposable container easily, defined and as completely as possible without the risk that parts of the contents of the disposable container accidentally splash or when opened emerge.
- a circumferential handle tab strip projecting downwards also arises on the sides on which no individual handle tab is provided.
- a circumferential crease line is formed between the flanging and this tab strip, which means a weakening of the material and thus forms a target tear line along which the lid tears open exactly, relatively easily and in a defined manner without the use of greater forces.
- the tearing process can be initiated at any point along the circumferential handle flap extension or along a bead, which can be further improved by providing an incision or a notch on a bead.
- the beads, the incision or the notch are formed obliquely, there is an even more favorable tearing transition from the grip tab via the flanging into the crease line between the flanging and the grip tab.
- incisions or notches can also be provided on these.
- the incision or the notch is preferably formed along the fold line of a bead.
- the cover blank for a cover can already be provided with a target tear-open area in the form of a circumferential material weakening strip (claims 8 and 9) in the area of the later flanged edge or the later flanging.
- the invention considerably simplifies the opening of a closed disposable container. Rolling lid parts can no longer arise. The risk of splashing parts of the contents of the container when opening is practically completely eliminated.
- the lid designed in accordance with the invention can be lifted effortlessly as a whole flat lid from the container after being torn open all around.
- the drawing shows a cover 2 with a circumferential, upwardly curved edge 4 and an adjoining, downwardly bent flanged edge strip 6 and an additional circumferential grip flap strip 46.
- An outwardly directed grip flap 8 or 10 is provided on two opposite cover sides.
- the lid has a rectangular shape with rounded corners 12, 14, 16 and 18.
- the handle straps are formed on the short sides of the rectangle 20, 22; but you can also choose the length Ren rectangular sides 24, 26 or be formed on all rectangular sides.
- An asymmetrically arranged profiling 30 is formed on the lid surface 28.
- the handle straps are, as shown (Fig. 1 and 2), also provided with a profile in the form of beads 32.
- the beads 32 are, as shown, rib-like elevations and can be, for example, rectangular or trapezoidal in section.
- the beads can run perpendicular (Fig. 1) or obliquely (Fig. 2) to the sides of the rectangle.
- the grip tabs can have different widths.
- an incision 36 or a notch 38 is preferably provided along a fold line 34 of this sikke.
- This incision or this notch need not extend over the entire length of the sikke, see reference numerals 40 and 42 in FIGS. 1 and 2.
- the flaring process creates a relatively sharp crease line 50 between the flare 44 and the strip 46 or the tab 48, which is formed all around underneath the flare 44.
- This kink line 50 represents a kind of predetermined tear line. If, for example, the cover 2 is torn open, for example on the grip tab 8, along the incision 36 or 40 or the notch 38 or 42, the cover tears open relatively easily exactly along the kink line 50 all around.
- the cover 2 can also be torn open along the flanging in a defined manner without providing incisions or notches. The lid can then be lifted off the container as a whole.
- the transition from the incision 36 or 40 or the notch 38 or 42 to the crease line 50 via the flange 44 is facilitated by the fact that, as shown in FIG. 2, the beads 32 are not perpendicular, but rather obliquely to the cover side or run to the flange 6.
- the other tab 10 can also be provided with an incision 52 and a notch 54, in order, if necessary, to be able to start the tearing process again here, if the tearing along the crease line 50 does not take place in one operation should go.
- FIGS. 7-9 show a cover 2, 2 'with a lid surface 4 and a circumferential flanged edge strip 6, 6', 6 "and an adjoining flap tab 46.
- the flanged edge strip 6, 6 ', 6" has a smaller one, at least in parts Thickness than the rest of the lid.
- the cover 21 is shown in the flanged state on a container 10 '.
- the material-weakened flanged edge strip 6 is flanged around a circumferential flanged edge or circumferential bead 12.
- the grip tab strip 46 is at the bottom.
- FIG. 8 shows a special possibility of weakening the flanged edge strip of the cover in a defined manner for the tearing process; the flanged edge strip is given the shape of an inwardly curved bead 6 '(FIG. 8 left) or an outwardly curved bead 6 "(FIG. 8 right) by reshaping, in this case by embossing.
- the bead may also run in an arched manner, as shown.
- the weakening of the material creates a desired tear-open area 6 ', 6 ", along which the lid 2, 21 can be torn open effortlessly and in a defined manner approximately at the circumference of the container 10', so that it can be removed from the container practically as a whole lid after the tear-open.

Description
Die Erfindung betrifft einen Deckel gemäss Oberbegriff des Anspruchs 1.The invention relates to a cover according to the preamble of
Es sind Deckel für Einwegbehälter bekannt. Ausser der Forderung der Stapelbarkeit und leichten Entstapelbarkeit sollen die Deckel möglichst auch noch einer weiteren Anforderung genügen: Sie sollten leicht zu öffnen sein, ohne dass die Gefahr besteht, dass Teile des Inhaltes des gefüllten Einwegbehälters beim Öffnen verspritzen. Das Öffnen stellt deshalb ein besonderes Problem dar, weil der Deckel durch Umbördein am umlaufenden Bördelrand der Einwegbehälter diesen Einwegbehälter dicht verschliessen muss.Lids for disposable containers are known. In addition to the requirement of stackability and easy unstackability, the lids should also meet another requirement if possible: they should be easy to open without the risk of parts of the contents of the filled disposable container splashing when opened. The opening is a special problem because the lid has to seal this disposable container tightly by flanging it on the circumferential flange edge of the disposable container.
Um das Öffnen des verschlossenen Einwegbehälters zu erleichtern, ist es durch die DE-A 2454645, die einen Deckel der eingangs genannten Art zeigt, und die DE-A 2140733 bekannt, am Deckel Aufreisslaschen vorzusehen, evtl. in Kombination mti vorbereiteten Reisslinien (DE-A 2140733). In der Praxis hat sich aber gezeigt, dass die aufgerissenen Deckelteile aufgrund der Eigenspannung federartig aufrollen und dabei beim Lösen vom Behälter anhaftende Speiseteile verspritzen. Auch gestaltet sich das Entfernen der weiteren noch am Behälter verbliebenen Deckelteile recht mühsam, wobei sogar die Gefahr einer Verletzung an den scharfen Risskanten besteht.In order to facilitate the opening of the closed disposable container, it is known from DE-A 2454645, which shows a lid of the type mentioned at the outset, and DE-A 2140733 to provide tear-open tabs on the lid, possibly in combination with prepared tear lines (DE- A 2140733). In practice, however, it has been shown that the torn-open lid parts roll up like a spring due to the inherent tension and in the process splash food parts adhering to them when detached from the container. The removal of the other lid parts still remaining on the container is also very laborious, and there is even a risk of injury to the sharp tear edges.
Die Aufgabe der vorliegenden Erfindung besteht deshalb darin, den Deckel der eingangs genannten Art so auszubilden, dass er vom verschlossenen Einwegbehälter leicht, definiert und möglichst vollständig entfernt werden kann, ohne dass die Gefahr besteht, dass Teile des Inhalts des Einwegbehälters beim Öffnen ungewollt verspritzen oder austreten.The object of the present invention is therefore to design the lid of the type mentioned at the outset in such a way that it can be removed from the closed disposable container easily, defined and as completely as possible without the risk that parts of the contents of the disposable container accidentally splash or when opened emerge.
Diese Aufgabe wird durch die Merkmale nach dem Kennzeichen des Anspruchs 1 gelöst.This object is achieved by the features according to the characterizing part of
Durch die Ausbildung nach Anspruch 1 entsteht auch an den Seiten, an denen keine einzelne Grifflasche vorgesehen ist, ein nach unten abstehender, umlaufender Grifflaschenstreifen. Zwischen der Bördelung und diesem Grifflaschenstreifen ist eine umlaufende Knicklinie ausgebildet, die eine Materialschwächung bedeutet und somit eine Soll-Aufreisslinie bildet, entlang der der Deckel beim Aufreissen exakt, relativ leicht und definiert ohne Anwendung grösserer Kräfte aufreisst.Due to the design according to
Vorteilhafte und zweckmässige Weiterbildungen der erfindungsgemässen Aufgabenlösung sind in den Ansprüchen 2 bis 7 angegeben.Advantageous and expedient developments of the task solution according to the invention are specified in
Der Einreissvorgang kann an beliebiger Stelle der umlaufenden Grifflaschenverlängerung oder entlang einer Sicke definiert eingeleitet werden, was durch das Vorsehen eines Einschnittes oder einer Einkerbung an einer Sicke noch verbessert werden kann.The tearing process can be initiated at any point along the circumferential handle flap extension or along a bead, which can be further improved by providing an incision or a notch on a bead.
Wenn die Sicken, der Einschnitt oder die Einkerbung schräg ausgebildet sind, erfolgt ein noch günstigerer Aufreissübergang von der Grifflasche über die Bördelung in die Knicklinie zwischen Bördelung und Grifflasche.If the beads, the incision or the notch are formed obliquely, there is an even more favorable tearing transition from the grip tab via the flanging into the crease line between the flanging and the grip tab.
Sind mehrere Grifflaschen vorgesehen, so können auch an diesen Einschnitte oder Einkerbungen vorgesehen werden. Vorzugsweise ist dabei der Einschnitt oder die Einkerbung entlang der Knicklinie einer Sicke ausgebildet.If several tabs are provided, incisions or notches can also be provided on these. The incision or the notch is preferably formed along the fold line of a bead.
Es kann bereits der Deckelzuschnitt für einen Deckel mit einem Soll-Aufreissbereich in Form eines umlaufenden Material-Schwächungsstreifens (Anspruch 8 und 9) im Bereich des späteren Bördelrandes bzw. der späteren Bördelung versehen werden.The cover blank for a cover can already be provided with a target tear-open area in the form of a circumferential material weakening strip (
Durch die Erfindung wird das Öffnen eines verschlossenen Einwegbehälters wesentlich vereinfacht. Sich aufrollende Deckelteile können nicht mehr entstehen. Die Gefahr eines Verspritzens von Teilen des Inhaltes des Behälters beim Öffnen ist praktisch vollständig beseitigt. Der erfindungsgemäss ausgebildete Deckel kann nach dem Rundumaufreissen praktisch als ganzer ebener Deckel vom Behälter mühelos abgehoben werden.The invention considerably simplifies the opening of a closed disposable container. Rolling lid parts can no longer arise. The risk of splashing parts of the contents of the container when opening is practically completely eliminated. The lid designed in accordance with the invention can be lifted effortlessly as a whole flat lid from the container after being torn open all around.

Gleiche Bauteile sind in den Figuren der Zeichnung mit den gleichen Bezugszeichen versehen.Identical components are provided with the same reference symbols in the figures of the drawing.
Die Zeichnung zeigt einen Deckel 2 mit einem umlaufenden, nach oben gewölbten Rand 4 und einen sich daran anschliessenden, nach unten gebogenen Bördelrandstreifen 6 und zusätzlichem umlaufenden Grifflaschenstreifen 46. An zwei gegenüberliegenden Deckelseiten ist jeweils eine auswärts gerichtete Grifflasche 8 bzw. 10 vorgesehen.The drawing shows a
Der Deckel hat eine rechteckförmige Form mit abgerundeten Ecken 12,14,16 und 18. Die Grifflaschen sind an den kurzen Rechteckseiten 20, 22 ausgebildet; sie können aber auch an den längeren Rechteckseiten 24, 26 oder an allen Rechteckseiten ausgebildet sein.The lid has a rectangular shape with
Auf der Deckeloberfläche 28 ist eine asymmetrisch angeordnete Profilierung 30 ausgebildet.An asymmetrically arranged profiling 30 is formed on the
Die Grifflaschen sind, wie dargestellt (Fig. 1 und 2), ebenfalls mit einer Profilierung in Form von Sicken 32 versehen. Die Sicken 32 sind, wie dargestellt, rippenartige Erhöhungen und können beispielsweise im Schnitt rechteckförmig oder trapezförmig ausgebildet sein. Die Sicken können senkrecht (Fig. 1) oder schräg (Fig. 2) zu den Rechteckseiten verlaufen. Die Grifflaschen können, wie dargestellt, unterschiedliche Breiten aufweisen.The handle straps are, as shown (Fig. 1 and 2), also provided with a profile in the form of
Entlang wenigstens einer Sicke 32, d.h. vorzugsweise entlang einer Knicklinie 34 dieser Sikke, ist ein Einschnitt 36 oder eine Einkerbung 38 vorgesehen. Dieser Einschnitt oder diese Einkerbung braucht nicht über die ganze Länge der Sikke zu verlaufen, vergl. Bezugszeichen 40 und 42 in den Fig. 1 und 2.Along at least one
Im umgebördelten Zustand verbleibt unterhalb der aus dem Bördelrandstreifen geformten Bördelung 44 ein nach unten zeigender Grifflaschen streifen 46, der an den nicht mit Grifflaschenverlängerungen 8 und 10 versehenen Rechteckseiten 24 und 26 eine relativ kurze Lasche 48 bildet.In the flanged state, underneath the
Durch den Bördelvorgang entsteht zwischen Bördelung 44 und Streifen 46 bzw. Lasche 48 eine relativ scharfe Knicklinie 50, die unterhalb der Bördelung 44 umlaufend ausgebildet ist. Diese Knicklinie 50 stellt eine Art Sollaufreisslinie dar. Wird nämlich der Deckel 2 beispielsweise an der Grifflasche 8 beginnend entlang des Einschnittes 36 bzw. 40 oder der Einkerbung 38 bzw. 42 aufgerissen, so reisst der Deckel relativ leicht genau entlang der Knicklinie 50 rundherum auf. Der Deckel 2 ist auch ohne Vorsehen von Einschnitten oder Einkerbungen definiert entlang der Bördelung aufreissbar. Der Deckel kann dann als Ganzes vom Behälter abgehoben werden.The flaring process creates a relatively
Der Übergang von dem Einschnitt 36 bzw. 40 oder der Einkerbung 38 bzw. 42 zur Knicklinie 50 über die Bördelung 44 wird dadurch erleichtert, dass, wie in der Fig. 2 dargestellt ist, die Sicken 32 nicht senkrecht, sondern schräg zur Deckelseite bzw. zum Bördelrand 6 verlaufen. In der Fig. 1 ist angedeutet, dass zusätzlich auch die andere Lasche 10 mit einem Einschnitt 52 und einer Einkerbung 54 versehen sein kann, um ggf. den Aufreissvorgang hier neu ansetzen zu können, falls das Aufreissen entlang der Knicklinie 50 nicht in einem Vorgang vonstatten gehen sollte.The transition from the
Fig. 7-9 zeigen einen Deckel 2, 2' mit einer Dekkelfläche 4 und einem umlaufenden Bördelrandstreifen 6, 6', 6" und einem sich daran anschliessenden Grifflaschenstreifen 46. Der Bördelrandstreifen 6, 6', 6" weist wenigstens in Teilen eine geringere Stärke als die übrigen Teile des Dekkels auf. In der Fig. 9 ist der Deckel 21 im umgebördelten Zustand auf einem Behälter 10' dargestellt. Der materialgeschwächte Bördelrandstreifen 6 ist dabei um einen umlaufenden Bördelrand bzw. umlaufenden Wulst 12 umgebördelt. Der Grifflaschenstreifen 46 steht dabei nach unten weg.7-9 show a
In der Fig. 8 ist eine spezielle Möglichkeit, den Bördelrandstreifen des Deckels definiert für den Aufreissvorgang zu schwächen, dargestellt; der Bördelrandstreifen erhält durch Umformen, hier durch Prägen, die Form einer einwärts gewölbten Sicke 6' (Fig. 8 links) oder einer auswärts gewölbten Sicke 6" (Fig. 8 rechts). Die Sicke kann anders als dargestellt auch bogenförmig verlaufen.FIG. 8 shows a special possibility of weakening the flanged edge strip of the cover in a defined manner for the tearing process; the flanged edge strip is given the shape of an inwardly curved bead 6 '(FIG. 8 left) or an outwardly
Durch die Materialschwächung entsteht ein Sollaufreissbereich 6', 6", entlang dem der Dekkel 2, 21 mühelos und definiert etwa am Umfang des Behälters 10' aufreissbar ist, so dass er nach dem Aufreissen praktisch als ganzer Deckel vom Behälter abnehmbar ist.The weakening of the material creates a desired tear-
