Abstract

The bag (10) has a rectangular base provided and made of stable material, where a base folding line (a) runs in a center between two longitudinal or transverse edges (34-37) and parallel to the two edges, where the base folding line divides the base into two base parts that are foldable against each other. The edges form side folding lines (b, c) between the base and two rectangular sidewalls (42, 44) that are arranged on two opposite sides of the base. A folding part (30) is stuck together with the bag, where the folding part is formed from the base and the two sidewalls.

Description

Die Erfindung betrifft einen Verpackungsbeutel aus einem flexiblen folienförmigen ersten Material, mit einem als Standfläche ausgebildeten, im wesentlichen rechteckigen Boden mit Längs- und Querkanten.The invention relates to a packaging bag made of a flexible film-shaped first material, with a standing surface formed as a substantially rectangular bottom with longitudinal and transverse edges.

Als standfeste Verpackungen für Nahrungsmittel, die im Mikrowellenofen erhitzt und auf einem Teller serviert werden, sind starre bzw. formfeste, üblicherweise durch 3D-Thermoforming oder Spritzguss hergestellte Behälter aus Kunststoff mit aufgesiegeltem Deckel und aus Kunststoff-Laminat gefertigte steife Beutel bekannt. Derartige Verpackungsbehälter und -beutel sind wegen ihres zur Erzielung der Standfestigkeit erhöhten Materialbedarfs ökologisch nicht unbedenklich und zudem verhältnismässig teuer.As sturdy packages for food heated in a microwave oven and served on a plate, rigid or rigid plastic containers usually made by 3D thermoforming or injection molding with a sealed lid and rigid plastic bags made of plastic laminate are known. Such packaging containers and bags are not ecologically harmless because of their increased to achieve the stability material requirements and also relatively expensive.

Schalenbehälter mit aufgesiegeltem Deckel haben den Nachteil, dass sie sperrig und leicht verletzlich sind.Cup containers with sealed lid have the disadvantage that they are bulky and easily vulnerable.

Der Erfindung liegt die Aufgabe zugrunde, eine Verpackung sowohl für trockene Produkte, wie z. B. Nüsse oder Chips, als auch für Produkte mit flüssigen und festen Anteilen oder halbfeste Produkte, wie z. B. im Mikrowellenofen aufzuwärmende Fertiggerichte, bereitzustellen, welche die vorstehend beschriebenen Nachteile der Verpackungen nach dem Stand der Technik nicht oder in geringerem Mass aufweist.The invention has for its object to provide a package for both dry products such. As nuts or chips, as well as for products with liquid and solid fractions or semi-solid products such. B. in the microwave oven to be reheated ready meals, which does not have the disadvantages of the prior art packaging described above or to a lesser extent.

Zur erfindungsgemässen Lösung der Aufgabe führt bei einem Verpackungsbeutel der eingangs genannten Art, dass der Boden aus einem dem Beutel in einem bodennahen Bereich Formstabilität verleihenden zweiten Material besteht, eine in der Mitte zwischen den beiden Längs- oder Querkanten und parallel zu diesen verlaufende, den Boden in zwei gegeneinander faltbare Bodenteile unterteilende Bodenfaltlinie aufweist, und die Längs- oder Querkanten Seitenfaltlinien zwischen dem Boden und auf zwei einander gegenüberliegenden Seiten des Bodens angeordneten, im wesentlichen rechteckigen Seitenwänden bilden, wobei ein aus dem Boden und den zwei Seitenwänden gebildetes Faltteil mit dem Beutel verklebt ist.For the inventive solution of the problem results in a packaging bag of the type mentioned that the bottom of a bag in a near-bottom area dimensional stability lending second material consists, one in the middle between the two longitudinal or transverse edges and parallel to these running, the ground in two mutually foldable floor parts dividing bottom fold line, and the longitudinal or transverse edge side fold lines between the bottom and arranged on two opposite sides of the bottom, substantially rectangular side walls form, wherein a folding part formed from the bottom and the two side walls is glued to the bag.

Ein wesentlicher Vorteil des erfindungsgemässen Verpackungsbeutels liegt einerseits in der flachen Beutelform der ersten Position, die sich ausgezeichnet für den Transport eignet, und andererseits in geöffnetem Zustand in der formstabilen und als Servier- oder Menüschale idealen Schalenform der zweiten Position.An essential advantage of the packaging bag according to the invention lies, on the one hand, in the flat pouch shape of the first position, which is excellently suited for transport, and on the other hand in the open state in the dimensionally stable shell shape of the second position which is ideal as a serving or menu shell.

Bei einer zweckmässigen Ausgestaltung des erfindungsgemässen Verpackungsbeutels weist das aus dem Boden und den zwei Seitenwänden aufgebaute Faltteil in einer ersten Position bezüglich einer senkrecht zu den Faltlinien gedachten Schnittebene eine im wesentlichen V-förmige Gestalt auf. In einer zweiten Position bilden die beiden Bodenteile einen im wesentlichen ebenen Boden als Standfläche und die beiden Seitenwände ragen vom Boden auf. Das aus dem Boden und den zwei Seitenwänden aufgebaute Faltteil ist aus der ersten Position durch Druck auf die die beiden Bodenteile verbindende Faltkante unter Ausbildung des im wesentlichen ebenen Bodens in die zweite Position bringbar.In an expedient embodiment of the packaging bag according to the invention, the folding part constructed from the base and the two side walls has a substantially V-shaped configuration in a first position with respect to a sectional plane perpendicular to the folding lines. In a second position, the two floor parts form a substantially flat floor as a standing surface and the two side walls protrude from the ground. The folding part constructed from the bottom and the two side walls can be brought from the first position into the second position by pressure on the folding edge connecting the two bottom parts to form the essentially flat bottom.

Bei einer spezielle Ausbildung des Faltteils verlaufen die Seitenfaltlinien bezüglich der Bodenfaltlinie nach aussen gekrümmt, so dass das aus dem Boden und den zwei Seitenwänden aufgebaute Faltteil in der zweiten Position eine stabile Form annimmt.In a specific embodiment of the folding part, the side fold lines are outwardly curved relative to the bottom fold line, so that the folding part constructed from the bottom and the two side walls assumes a stable shape in the second position.

Das bodenfeme Ende des Beutel ist bevorzugt entlang einer im wesentlichen parallel zur Standfläche des Beutels liegenden Aufreisslinie abtrennbar.The bottomed end of the bag is preferably separable along a tear line lying substantially parallel to the base of the bag.

Der Verpackungsbeutel selbst kann ein Standbeutel ohne eigene Standfestigkeit, ein Schlauchbeutel oder ein extrudierter Beutel sein. Das Beutelmaterial für den erfindungsgemässen Verpackungsbeutel kann im Vergleich zu dem für einen Standbeutel mit eigener Standfestigkeit benötigten steifen Material eine geringere Dicke aufweisen und ist demzufolge kostengünstig.The packaging bag itself can be a stand-up bag without its own stability, a tubular bag or an extruded bag. The bag material for the inventive packaging bag can in comparison to that for a stand-up bag with its own stability required rigid material have a smaller thickness and is therefore inexpensive.

Das Beutelmaterial des erfindungsgemässen Verpackungsbeutels ist bevorzugt eine ein- oder mehrschichtige, gegebenenfalls mit einer Papierschicht oder mit einer Aluminiumfolie laminierte Folie aus Kunststoff oder ein mit Kunststoff laminiertes Papier.The bag material of the packaging bag according to the invention is preferably a single-layer or multi-layered film of plastic, which is optionally laminated with a paper layer or with an aluminum foil, or a paper laminated with plastic.

Das Material für das Faltteil und das Verstärkungsteil kann aus irgendeinem kostengünstigen Material sein. Ein bevorzugtes Material ist Karton oder ein transparenter oder opaker Kunststoff.The material for the folding part and the reinforcing part may be made of any inexpensive material. A preferred material is cardboard or a transparent or opaque plastic.

Der Verpackungsbeutel eignet sich insbesondere zur Verpackung von Nahrungsmitteln, insbesondere löffelbaren Füllgütern. Ein weiterer bevorzugter Anwendungsbereich liegt in der Verpackung von Füllgütern, die zur Erhitzung in einem Mikrowellenofen vorgesehen sind.The packaging bag is particularly suitable for packaging food, in particular spoonable filling goods. Another preferred application is in the packaging of products intended for heating in a microwave oven.

Die Erwärmung von Speisen, wie z.B. Fertiggerichten, kann im erfindungsgemässen Verpackungsbeutel im geöffneten Zustand direkt in einem Mikrowellengerät erfolgen. Der Vorteil des erfindungsgemässen Verpackungsbeutels liegt hier in der wärmeisolierenden Ausgestaltung des bodennahen Bereichs des Beutels durch das Faltteil, das ein Anfassen mit der blossen Hand ermöglicht. Gewisse Speisen können im geöffneten Beutel beispielsweise auch in einem Wasserbad erwärmt werden. Bei Fertiggerichten kann der geöffnete Beutel direkt als Menüschale dienen,The heating of food, e.g. Ready meals, can be done in the inventive packaging bag in the open state directly in a microwave oven. The advantage of the packaging bag according to the invention lies in the heat-insulating design of the bottom region of the bag through the folding part, which allows it to be grasped with the bare hand. Certain foods can be heated in the open bag, for example, in a water bath. In ready meals, the opened bag can serve directly as a menu tray,

Ein in den Fig. 1 und 2 gezeigter Verpackungsbeutel 10 in der Form eines aus einem flexiblen Folienmaterial, wie z. B. Polyamid, bestehenden Standbeutels weist einen eingesiegelten Beutelboden 12, eine Vorderwand 14 und eine Rückwand 16 auf. Vorderwand 14 und Rückwand 16 sind in bekannter Art über seitliche Längssiegelnähte 18, 19 verbunden und führen zusammen mit einer am bodenfemen Ende des Beutels 10 angeordneten Quersiegelnaht 20 zum verschlossenen Verpackungsbeutel 10.A shown in Figs. 1 and 2 packaging bag 10 in the form of a flexible sheet material such. As polyamide, existing bag has a sealed bag bottom 12, a front wall 14 and a rear wall 16. Front wall 14 and rear wall 16 are connected in a known manner via lateral longitudinal sealing seams 18, 19 and, together with a transverse seam 20 arranged at the bottom end of the bag 10, lead to the closed packaging bag 10.

Die Quersiegelnaht 20 am bodenfemen Ende des Verpackungsbeutels 10 ist Teil eines vom Beutel abtrennbaren Beutelteils 24 und ist von einem V-förmigen Verstärkungsteil 22 übergriffen. Das Verstärkungsteil 22 ist mit einem durchgehenden Schlitz 26 zum Aufhängen des Beutels 10 ausgestattet. Zum Öffnen des Verpackungsbeutels 10 wird das abtrennbare Beutelteil 24 entlang einer in den Beutelwänden 14, 16 parallel und in kurzem Abstand zur Quersiegelnaht 20 angeordneten Aufreisslinie 28 zusammen mit dem Verstärkungsteil 22 weggerissen. Als Aufreisshilfe sind in den Längssiegelnähten 18,19 Aufreisskerben mit an der Aufreisslinie 28 endender Spitze vorgesehen.The transverse sealing seam 20 at the bottom end of the packaging bag 10 is part of a bag part 24 which can be separated from the bag and is overlapped by a V-shaped reinforcing part 22. The reinforcing member 22 is provided with a continuous slot 26 for suspending the bag 10. To open the packaging bag 10, the detachable bag part 24 along a tear in the bag walls 14, 16 parallel and at a short distance from the transverse seam 20 arranged tear line 28 together with the reinforcing member 22 is torn away. As a tear-open in the longitudinal sealing seams 18,19 rupture scores are provided with ending at the tear line 28 tip.

Im bodennahen Bereich des Beutels 10 ist ein sich von der Beutelvorderwand 14 zur Rückwand 16 erstreckendes, den Beutelboden 12 einschliessendes Faltteil 30 aus einem im wesentlichen formstabilen Material, wie z. B. Karton, angeordnet.In the bottom region of the bag 10 is a from the bag front wall 14 to the rear wall 16 extending, the bag bottom 12 enclosing folding part 30 of a substantially dimensionally stable material, such. As cardboard, arranged.

Das Faltteil 30 besteht aus einem rechteckigen Boden 32 mit Längskanten 34, 35 und Querkanten 36, 37. Eine in der Mitte zwischen den beiden Längskanten 34, 35 und parallel zu diesen verlaufende Bodenfaltlinie a unterteilt den Boden 32 in zwei gegeneinander faltbare Bodenteile 38, 40. Die Längskanten 34, 35 des Bodens 32 bilden Seitenfaltlinien b, c zwischen dem Boden 32 und im wesentlichen rechteckigen Seitenwänden 42, 44, die an zwei einander gegenüberliegenden Seiten des Bodens 32 angeordnet sind. Das aus dem Boden 32 und den zwei Seitenwänden 42, 44 aufgebaute Faltteil 30 ist zumindest teilweise an der Beutelaussenseite befestigt. Die Befestigung an den Beutelwänden 14, 16 erfolgt z. B. partiell über punktuelle Klebestellen.The folding part 30 consists of a rectangular bottom 32 with longitudinal edges 34, 35 and transverse edges 36, 37. A in the middle between the two longitudinal edges 34, 35 and parallel to these extending bottom fold line a divides the bottom 32 into two mutually foldable bottom parts 38, 40th The longitudinal edges 34, 35 of the bottom 32 form side fold lines b, c between the bottom 32 and substantially rectangular side walls 42, 44 disposed on two opposite sides of the bottom 32. The folding part 30 constructed from the bottom 32 and the two side walls 42, 44 is at least partially fixed to the bag outer side. The attachment to the bag walls 14, 16 takes place for. B. partially over punctual splices.

Aus Fig. 1 ist ersichtlich, dass das aus dem Boden 32 und den zwei Seitenwänden 42, 44 aufgebaute Faltteil 30 in einer ersten Position bezüglich einer senkrecht zu den Faltlinien a, b, c gedachten Schnittebene eine im wesentlichen V-förmige Gestalt aufweist. In einer aus Fig. 2 ersichtlichen zweiten Position bilden die beiden Bodenteile 38, 40 den im wesentlichen ebenen Boden 32 als Standfläche, und die beiden Seitenwände 42. 44 ragen im wesentlichen senkrecht vom Boden auf. Das aus dem Boden 32 und den zwei Seitenwänden 42, 44 gebildete Faltteil 30 wird aus der ersten Position durch Druck von der Aussenseite auf die die beiden Bodenteile 38, 40 verbindende Bodenfaltkante bzw. -linie unter Ausbildung des im wesentlichen ebenen Bodens 32 in die zweite Position gebracht. Die Umwandlung des in der ersten Position V-fömzigen Faltteils 30 in die zweite Position-mit ebenem Boden 32 und von diesem aufragenden Seitenwänden 42, 44 ergibt sich automatisch beim Aufstellen des Beutels 10 in seine aufrechte Position.From Fig. 1 it can be seen that the folding member 30 constructed of the bottom 32 and the two side walls 42, 44 has a substantially V-shaped configuration in a first position with respect to a sectional plane perpendicular to the fold lines a, b, c. 2, the two bottom parts 38, 40 form the substantially flat bottom 32 as a standing surface, and the two side walls 42, 44 protrude substantially perpendicularly from the bottom. The folding part 30 formed from the bottom 32 and the two side walls 42, 44 becomes from the first position by pressure from the outside on the Bodenfaltkante connecting the two bottom parts 38, 40 Bodenfaltkante or line to form the substantially flat bottom 32 in the second Position brought. Conversion of the folding member 30, which is in the first position V-shaped, to the second flat-bottomed position 32 and upwardly projecting sidewalls 42, 44 results automatically when the bag 10 is placed in its upright position.

Der Boden 32 dient als Standfläche, so dass der Verpackungsbeutel 10 selbst nicht standfest ausgebildet sein muss. Der Verpackungsbeutel 10 kann daher auch ein einfacher Schlauchbeutel mit einer Längsnaht, oder ein extrudierter Beutel ohne Längsnaht, und zwei Quemähten sein.The bottom 32 serves as a base, so that the packaging bag 10 itself does not have to be made stable. The packaging bag 10 may therefore also be a simple tubular bag with a longitudinal seam, or an extruded bag without a longitudinal seam, and two stitched seams.

Aus Fig. 2 ist erkennbar, dass der Beutel 10 nach dem Öffnen zusammen mit dem speziell gestalteten Faltteil 30 eine Schale mit im wesentlichen rechteckigem Boden bildet. Je nach Beutelinhalt kann die gebildete Schale u.a. als Servierschale für z.B. Nüsse oder Chips oder als Mikrowellenofen taugliche Menüschale für z.B.
