Description
Verpackungsbeutelpacking bags
Die Erfindung betrifft einen Verpackungsbeutel aus einem flexiblen folienförmi- gen 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 foil-like 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 sper- rig und leicht verletzlich sind.Cup containers with a 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 aufzu- wärmende 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-heated ready meals to provide, 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 Verpackungs- beutel 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 pa- rallel 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 Seiten- wänden bilden, wobei ein aus dem Boden und den zwei Seitenwänden gebildetes Faltteil mit dem Beutel verklebt ist.In order to achieve the object according to the invention in a packaging bag of the type mentioned at the outset, the bottom consists of a second material which imparts dimensional stability to the bag in a ground-level region, one in the middle between the two longitudinal or transverse edges and parallel to these extending, the floor in two mutually foldable floor parts dividing bottom fold line, and the longitudinal or transverse edges Seitenfaltlinien between the bottom and arranged on two opposite sides of the floor, form substantially rectangular side walls, one from the ground and the two side walls formed folding part 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 Verpa- ckungsbeutels 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 relative to a sectional plane imaginary 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 moved 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 bodenferne Ende des Beutel ist bevorzugt entlang einer im wesentlichen parallel zur Standfläche des Beutels liegenden Aufreisslinie abtrennbar. 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 bottom-distal end of the bag is preferably separable along a tear line lying substantially parallel to the base of the bag. 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 packaging bag according to the invention can have a smaller thickness in comparison to the stiff material required for a stand-up bag with its own stability and is consequently 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 Ia- miniertes 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 impregnated 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.

Als Aufreisshilfe sind in den Längssiegelnähten 18,19 Anrisskerben mit an der Aufreisslinie 28 endender Spitze vorgesehen.The transverse sealing seam 20 at the bottom-distal 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 separable bag part 24 is moved along one in the bag walls 14, 16 parallel and at a short distance to the transverse seam 20 arranged tearing line 28 torn away along with the reinforcing member 22. As a tear-open in the longitudinal sealing seams 18.19 tear notches provided with 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 verstärkendes Faltteil 30 aus einem im wesentlichen formstabilen Material, wie z. B. Karton, Kunststoff, einem anderen geeigneten Material oder aus einem Laminat aus den vorgenannten und gegebenenfalls weiteren Werkstoffen angeordnet. Das Faltteil 30 kann am Beutelboden 12 im Inneren des Beutels angeordnet sein oder den Beutelboden 12 von aussen umschliessen.Near the bottom of the bag 10 is a from the bag front wall 14 to the rear wall 16 extending, the bag bottom 12 reinforcing folding member 30 of a substantially dimensionally stable material, such. As cardboard, plastic, another suitable material or a laminate of the aforementioned and optionally other materials. The folding part 30 may be arranged on the bag bottom 12 in the interior of the bag or enclose the bag bottom 12 from the outside.
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.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.
Das aus dem Boden 32 und den zwei Seitenwänden 42, 44 aufgebaute Faltteil 30 kann, wie vorstehend erwähnt, sowohl im Inneren des Beutels als auch an dessen Aussenseite angeordnet sein und ist zumindest teilweise an der Beutelinnen- bzw. -aussenseite durch Verkleben, Siegeln und dergleichen Verbin- dungsarten befestigt. Die Befestigung an den Beutelwänden 14, 16 erfolgt z. B. partiell über punktuelle Klebe- oder Siegelstellen.The folding member 30 constructed of the bottom 32 and the two side walls 42, 44 may, as mentioned above, be arranged both inside the bag and on the outside thereof and is at least partially adhered to the bag inside and outside by gluing, sealing and attached to the same types of connection. The attachment to the bag walls 14, 16 takes place for. B. partially over punctate adhesive or sealing sites.
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 senk- recht 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 Aus- senseite auf die die beiden Bodenteile 38, 40 verbindende Bodenfaltkante bzw. -linie a unter Ausbildung des im wesentlichen ebenen Bodens 32 in die zweite Position gebracht. Die Umwandlung des in der ersten Position V-förmigen 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.It can be seen from FIG. 1 that the folding part 30 constructed from the base 32 and the two side walls 42, 44 has a substantially V-shaped configuration in a first position with respect to a sectional plane which is perpendicular to the folding lines a, b, c , In a second position shown in FIG. 2, the two bottom parts 38, 40 form the substantially flat bottom 32 as Stand surface, and the two side walls 42, 44 project substantially perpendicularly from the ground. The folding part 30 formed from the bottom 32 and the two side walls 42, 44 becomes the bottom folding edge or line a connecting the two bottom parts 38, 40 from the first position by pressure from the outside, forming the substantially flat bottom 32 placed in the second position. The conversion of the folding in the first position V-shaped folding member 30 in the second position with a flat bottom 32 and from this towering side walls 42, 44 results automatically when setting the bag 10 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 Quernähten 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 can therefore also be a simple tubular bag with a longitudinal seam, or an extruded bag without a longitudinal seam, and two transverse 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 Menü- schale für z.B. Fertigmahlzeiten dienen.From Fig. 2 it can be seen that the bag 10 after opening together with the specially designed folding part 30 forms a shell having a substantially rectangular bottom. Depending on the contents of the bag, the shell formed may be u.a. as a serving bowl for e.g. Nuts or chips or a microwave oven suitable for use with e.g. Serve ready meals.
Bei einem in Fig. 3 dargestellten Faltteil 30 verlaufen die Seitenfaltlinien b, c bezüglich der Bodenfaltlinie a nach aussen gekrümmt, so dass das aus dem Boden 32 und den zwei Seitenwänden 42, 44 aufgebaute Faltteil 30 in der in den Fig. 4 bis 6 gezeigten zweiten Position eine stabile Form annimmt.In a folding part 30 shown in FIG. 3, the side folding lines b, c are outwardly curved with respect to the bottom folding line a, so that the folding part 30 constructed of the bottom 32 and the two side walls 42, 44 is as shown in FIGS second position assumes a stable shape.
Wie in den Fig. 4 bis 6 dargestellt, bilden die Seitenwände 42, 44 in der zweiten Position des Faltteils 30 konvex gekrümmten Flächen und der Boden 32 fällt kurz vor Erreichen der zweiten Position spontan in eine formstabile, konkav ge- krümmte Endlage.As shown in FIGS. 4 to 6, the side walls 42, 44 in the second position of the folding part 30 form convexly curved surfaces, and the bottom 32 spontaneously falls into a dimensionally stable, concavely curved end position shortly before reaching the second position.
Die Fig. 7 bis 10 zeigen beispielhafte Ausführungen von Verpackungsbeuteln mit wiederverschliessbarem Öffnungsteil.FIGS. 7 to 10 show exemplary embodiments of packaging bags with resealable opening part.
Bei einer in Fig. 7 und 8 dargestellten ersten Variante wird zum Öffnen des Verpackungsbeutels 10 der Beutelteil mit der Quersiegelnaht 20 entlang einer in den Beutelwänden 14, 16 parallel und in kurzem Abstand zur Quersiegelnaht 20 angeordneten Aufreisslinie 28 weggerissen. Als Aufreisshilfe sind in den Längssiegelnähten 18,19 Anrisskerben 46 mit an der Aufreisslinie 28 endender Spitze vorgesehen.In a first variant shown in FIGS. 7 and 8, to open the packaging bag 10, the bag part with the transverse sealing seam 20 is torn away along a tear line 28 arranged in the bag walls 14, 16 in parallel and at a short distance from the transverse sealing seam 20. As a tear-open in the longitudinal sealing seams 18.19 tear scores 46 are provided with terminating at the tear line 28 tip.
In einem weiteren Abstand zur Quersiegelnaht 20 und zur Aufreisslinie 28 sind parallel zur Quersiegelnaht 20 an den Beutelwänden 14, 16 korrespondierende Teile eines Zipperverschlusses 48, 49 angeordnet. Nachdem der Beutel durch Wegreissen des Beutelteils mit der Quersiegelnaht 20 entlang der Aufreisslinie 28 geöffnet wurde, kann der Beutel mittels des Zipperverschlusses 48, 49 wie- derholt geöffnet und wieder verschlossen werden.At a further distance from the transverse sealing seam 20 and the tear-open line 28, corresponding parts of a zipper closure 48, 49 are arranged parallel to the transverse sealing seam 20 on the bag walls 14, 16. After the bag has been opened by tearing the bag part with the transverse sealing seam 20 along the tear line 28, the bag can be repeatedly opened and closed again by means of the zip fastener 48, 49.
Bei einer in Fig. 9 und 10 dargestellten zweiten Variante wird zum Öffnen des Verpackungsbeutels 10 wiederum zunächst der Beutelteil mit der Quersiegelnaht 20 entlang einer in den Beutelwänden 14, 16 parallel und in kurzem Ab- stand zur Quersiegelnaht 20 angeordneten Aufreisslinie 28 weggerissen. Als Aufreisshilfe sind in den Längssiegelnähten 18, 19 Anrisskerben 46 mit an der Aufreisslinie 28 endender Spitze vorgesehen.In a second variant shown in FIGS. 9 and 10, in order to open the packaging bag 10, the bag part with the transverse sealing seam 20 is torn away along a tear line 28 arranged parallel to and at a short distance from the transverse sealing seam 20 in the bag walls 14, 16. As a tear-open are provided in the longitudinal sealing seams 18, 19 tear scoring 46 with the tear line 28 ending tip.
In einem weiteren Abstand zur Quersiegelnaht 20 und zur Aufreisslinie 28 ist ein die beiden Beutelwände 14, 16 über einen Haftkleber verbindender, peelba- rer und wiederverschliessbarer Verschlussstreifen 50 angeordnet. Nachdem der Beutel durch Wegreissen des Beutelteils mit der Quersiegelnaht 20 entlang der Aufreisslinie 28 geöffnet wurde, kann der Beutel mittels des Verschlussstreifens 50 wiederholt geöffnet und wieder verschlossen werden. Um das Öffnen zu er- leichtern, ist der Verschlussstreifen 50 von den Längssiegelnähten 18, 19 ausgehend gegen die Quersiegelnaht 20 pfeilförmig ansteigend ausgebildet. Auf diese Weise ist die Kraft beim Öffnen auf die Mitte des Verschlussstreifens 50 konzentriert und die Trennung des Verschlussstreifens 50 erfolgt kontinuierlich von der Mitte des Beutels gegen die beiden Längssiegelränder 18, 19.At a further distance from the transverse sealing seam 20 and the tear-open line 28, a peelable and resealable closure strip 50 connecting the two bag walls 14, 16 via a pressure-sensitive adhesive is arranged. After the bag has been opened by tearing away the bag part with the transverse sealing seam 20 along the tear line 28, the bag can be repeatedly opened and closed again by means of the closure strip 50. In order to facilitate the opening, the closure strip 50 is formed starting from the longitudinal sealing seams 18, 19 in an arrow-shaped rising manner against the transverse sealing seam 20. In this way, the force upon opening is at the center of the closure strip 50 concentrated and the separation of the closure strip 50 is carried out continuously from the center of the bag against the two longitudinal sealing edges 18, 19th
Die in der Zeichnung dargestellten Öffnungs- und Wiederverschliesssysteme sind lediglich eine kleine Auswahl aus einer Vielzahl von Möglichkeiten zum wiederverschliessbaren Öffnen eines Beutels. Der Schutzbereich des erfin- dungsgemässen Verpackungsbeutel ist nicht auf die in der Zeichnung dargestellten Ausführungsbeispiele beschränkt , sondern erstreckt sich vielmehr auf Verpackungsbeutel mit beliebigen Öffnungs- und gegebenenfalls Wiederver- schliesssystemen. The opening and reclosing systems shown in the drawings are but a small selection of a variety of ways to re-close a bag. The scope of protection of the packaging bag according to the invention is not limited to the exemplary embodiments shown in the drawing, but rather extends to packaging bags with any opening and possibly re-closing systems.
