Die Umverpackung weist bevorzugt aus zwei bezüglich der Faltkanten rotationssymmetrischen Hälften bestehende seitliche Öffnungen auf, wobei die Teillängen Verbindungslinien der rotationssymmetrischen Hälften der seitliche Öffnungen entsprechen.The outer packaging preferably comprises two lateral openings which are rotationally symmetrical with respect to the folding edges, the partial lengths corresponding to connecting lines of the rotationally symmetrical halves of the lateral openings.
Das Beutelmaterial ist bevorzugt eine ein- oder mehrschichtige, gegebenenfalls mit einer Papierschicht laminierte Folie aus Kunststoff oder ein mit Kunststoff laminiertes Papier und liegt vorzugsweise als Monomaterial vor, und das Umverpackungsmaterial ist bevorzugt Karton oder ein transparenter oder opaker Kunststoff und liegt vorzugsweise als Monomaterial vor.The bag material is preferably a single-layer or multi-layered film, optionally laminated with a paper layer, of plastic or a paper laminated with plastic and is preferably present as a monomaterial, and the outer packaging material is preferably cardboard or a transparent or opaque plastic and is preferably present as a monomaterial.
Bevorzugt ist der Verpackungsbeutel über punktuelle Klebestellen an der Innenwand der Umverpackung befestigt.Preferably, the packaging bag is attached via punctiform splices to the inner wall of the outer packaging.
Der Verpackungsbeutel ist bevorzugt ein Standbeutel, ein Schlauchbeutel oder ein extrudierter Beutel.The packaging bag is preferably a stand-up pouch, a tubular pouch or an extruded pouch.
An der eine Standfläche bildenden Öffnung können zwei einander gegenüberliegende Kanten eine von der Standfläche weg weisende Krümmung aufweisen. Die bewirkt in der formstabilen Position eine erhöhte Stabilität der Standfläche.At the opening forming a base, two opposite edges may have a curvature pointing away from the base. The causes in the dimensionally stable position increased stability of the base.
An der Umverpackung kann ein Boden mit einer Einstecklasche oder ein Automatikboden vorgesehen sein.On the outer packaging may be provided with a bottom tab or an automatic bottom.
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. Die nach dem Entfernen des Öffnungsteils durch seitlichen Druck auf die Faltkanten der Umverpackung gebildete Entnahmeöffnung bleibt dank der formstabilen zweiten Position der Umverpackung vollständig und dauerhaft geöffnet.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. The after removal of the opening part by lateral pressure on the folded edges of the outer packaging formed removal opening remains fully and permanently open thanks to the dimensionally stable second position of the outer packaging.
Das Beutelmaterial des erfindungsgemässen Verpackungsbeutels ist bevorzugt eine ein- oder mehrschichtige, gegebenenfalls mit einer Papierschicht laminierte Folie aus Kunststoff oder ein mit Kunststoff laminiertes Papier und liegt vorzugsweise als Monomaterial vor.The bag material of the packaging bag according to the invention is preferably a single-layer or multi-layered film of plastic, which may be laminated with a paper layer, or a paper laminated with plastic, and is preferably present as a monomaterial.
Zur Vermeidung einer Migration von Fremdstoffen in das Beutelinnere ist der Verpackungsbeutel bevorzugt unbedruckt.To avoid migration of foreign substances into the bag interior, the packaging bag is preferably unprinted.
Das Umverpackungsmaterial kann aus irgendeinem kostengünstigen Monomaterial sein. Ein bevorzugtes Umverpackungsmaterial ist Karton, Wellkarton oder ein transparenter oder opaker Kunststoff. Für die Umverpackung eignen sich beispielsweise auch Stärke, Mais und dgl. bioabbaubare Materialien. Die Umverpackung kann beliebig bedruckt sein.The overwrap material may be of any inexpensive monomaterial. A preferred outer packaging material is cardboard, corrugated cardboard or a transparent or opaque plastic. For example, starch, maize and the like are also suitable for the outer packaging. Biodegradable materials. The outer packaging can be printed as desired.
Der Verpackungsbeutel eignet sich insbesondere zur Verpackung von trinkbaren oder löffelbaren Füllgütern sowie von mit Flüssigkeit zu trinkbaren oder löffelbaren Produkten anrührbaren Füllgütern. Ein weiterer bevorzugter Anwendungsbereich liegt in der Verpackung von Füllgütern, die zur Erhitzung in einem Mikrowellenofen vorgesehen sind. Auch für Tiernahrungsmittel sowie für weitere Füllgüter, wie z. B. Waschpulver und andere schütt- und rieselfähige Füllgüter, ist die Verpackung geeignet.The packaging bag is suitable in particular for the packaging of drinkable or spoonable filling products as well as of fillable products which can be stirred with liquid to drinkable or spoonable products. Another preferred application is in the packaging of products intended for heating in a microwave oven. Also for animal food and for other products, such. As washing powder and other pourable and free-flowing products, the packaging is suitable.
Die Erwärmung von Speisen wie z. B. Suppen kann im erfindungsgemässen Verpackungsbeutel zusammen mit der Umverpackung im geöffneten Zustand, gegebenenfalls nach dem Anrühren mit kaltem Wasser, direkt in einem Mikrowellengerät erfolgen. Der Vorteil der erfindungsgemässen Verpackungseinheit liegt hier in der wärmeisolierenden Umverpackung, die ein Anfassen mit der blossen Hand ermöglicht. Die Verwendung von Wellkarton als Material für die Umverpackung führt zu einer besonders wärmeisolierenden Ausgestaltung.The heating of food such. B. soups can be done in the inventive packaging bag together with the outer packaging in the open state, optionally after mixing with cold water directly in a microwave oven. The advantage of the packaging unit according to the invention lies in the heat-insulating outer packaging, which makes it possible to touch it with the bare hand. The use of corrugated cardboard as a material for the outer packaging results in a particularly heat-insulating design.
Bei Wasser mit und ohne Kohlensäure dient das Verpackungssystem zur Aufbewahrung des Füllgutes und gleichzeitig als Trinkgefäss.In the case of water with and without carbonic acid, the packaging system serves to store the contents and at the same time as a drinking vessel.
Je nach Art des Füllguts wird dieses noch mit Flüssigkeit angerührt, wie z. B. Beutelsuppen mit heissem Wasser, oder das Füllgut liegt bereits in flüssiger oder löffelbarer Form vor, z. B. Jogurt.Depending on the type of contents this is still mixed with liquid, such as. As bag soups with hot water, or the product is already in liquid or spoonable form, z. B. yogurt.

Die Quersiegelnaht 20 am bodenfernen Ende des Verpackungsbeutels 10 ist Teil eines vom Beutel abtrennbaren Öffnungsteils 26. Zur Öffnung des Verpackungsbeutels 10 wird das Öffnungsteil 26 entlang einer in den Beutelwänden 14, 16 parallel und in kurzem Abstand zur Quersiegelnaht 20 angeordneten Aufreisslinie 24 weggerissen. Als Aufreisshilfe sind in den Längssiegelnähten 18,19 Aufreisskerben 22, 23 mit an der Aufreisslinie 24 endender Spitze vorgesehen.The
