Definitions
- the invention relates to a packaging container according to the preamble of claim 1.
- Packaging containers of this kind are widely used in the form of side-folding bags or bottom-folding bags and not only offer a packaging expenditure that is small in terms of space, volume and costs but can also be effectively manufactured, filled and sealed in well-developed machine throughputs.
- a rectangular shape of the (filled) packaging which is regularly desired for storage, shipping and product representation can only be produced in a nutshell in conventional conventional packaging since it requires a complete filling that is difficult to achieve and because deformations generally occur easily with free-flowing packaged goods.
- the packages are brought together at one (head) end to a removal opening, where possibly also gussets converge and possibly at the other end a central bottom cross seam forms the conclusion, packaging tend to incomplete filling to variable forms.
- the installation of the packaging is uncertain.
- packages are poorly accessible via a removal opening provided with a reclosure, as far as the withdrawal slot is short and possibly even affected by gussets in the head ending.
- Packing container of the type mentioned with substantially parallelepiped, but in gusseted end gusset walls between the main walls, which converge at opposite ends to a middle seam or strip, in particular as bottom seam or head strip, are, for example DE 10 2008 011 471 A1 .
- a packaging container with a bottom pleat wall and a header formed with a reclosure is off EP 1 266 836 A1 seen.
- EP 2 277 790 A1 is a packaging container according to the preamble of claim 1 can be seen in which the main and side walls and a bottom wall are joined together like a box on sealing seams, the head area is extended with excess film areas to handle strips and equipped in a handle bar with a running over the entire width reclosure.
- This head design complicates a complete filling into a cuboid shape and is therefore only conditionally possible.
- the object of the invention is to provide a packaging container, which allows a better degree of filling with lumpy or free-flowing material, it better feeds to the desired parallelepiped shape, which is thus well set up on side or end walls and the widest and easily accessible Removal opening with a reclosure allows.
- the object is achieved by a packaging container according to the preamble of claim 1 with the characterizing features of claim 1.
- An essential step in the solution of this task is according to the invention in that the removal opening extends along one of the longitudinal edges.
- the conventionally arranged in a production technology in the head of a packaging container removal opening is moved to one of the longitudinal edges, which allow even from the edge length ago a larger or longer filling opening / removal opening, which is accordingly wider and more convenient to open.
- this area of the packaging container is also readily to be kept free from the integration or completion of side gusseted walls of a conventional type and, in this respect, can easily be accessed undisturbed.
- the displacement of the removal opening towards the side edge and away from an arrangement from a central region of the container walls results in that the adjacent walls of the container are bent up substantially flat when opened and accordingly are not very bulky.
- the removal opening running "along" a longitudinal edge does not have to be placed exactly symmetrically on the longitudinal edge; rather, the design of the reclosure can lead to it being placed directly adjacent to one or the other (main or side) wall.
- the reclosure is formed with two reclosure strips, which have an irreversible in the first opening réelletutede connection.
- This has the advantage offered in the distribution of packaging azihin and also with commercial reclosures the "novelty guarantee" in the sale and the integrity of the delivery.
- reclosing strips are in this way against breakage in case of special stresses of the packaging container in shipping and distribution additionally secure. Reclosures with, for example, two reclosing strips which can be closed or opened with latching profile strips, if necessary also a longitudinally movable slide, can be secured and sealed by a separable connection between the reclosure strips. But until the first opening reclosure strips can be connected to each other via a peelable (removable) film web, which allows a tool-free initial opening.
- the empty and so still to be filled packaging bag can be conveniently provided with a wide filling opening, which is closed after filling, according to the invention, this filling opening is not placed in a conventional manner directly adjacent to the removal opening and adjacent to the reclosure but better along a the other longitudinal edges or in one of the transverse edges runs.
- the filling opening to be closed only after filling for example with a sealed seam, can be designed to be wide and easily accessible independently of the removal opening and its reclosure. This allows not only a convenient filling but also a high degree of filling, which improve to a residual volume of well below 5% instead of the conventional 10% to 15% leaves.
- a protruding filler neck which is easy to close and separate after filling with a separating sealing seam.
- a filler neck can be formed for example by projecting film areas from the adjacent walls, which are pulled out as strips lying adjacent to each other and are connected to one another at the edges to form a tube.
- packaging containers of the type considered here exceed a "manageable” measure, they can expediently be provided with at least one handle, which can advantageously be folded flat with the packaging container.
- a handle is not only for the buyer-side handling when home transport a filled packaging container advantage but also when opening to raise it on the handle one side of the removal opening.
- the handle may be a film-formed strip attached flat to one of the walls. For mounting, it can be arranged at a predetermined distance from the reclosure on one of the walls.
- a tubular shape such as a tubular extruded blown film, but more generally a tubular shape made of a flat seam formed with a longitudinal seam to the tube, the open end cross-sections are at a mutual distance corresponding to the cuboid shape and closed by end walls on all sides edge seams.
- the longitudinal seam for the hose can advantageously be laid in the edge.
- the tubular shape can also be achieved by sealing the individual walls, such as the main and side walls, by four side seams forming the longitudinal edges, the longitudinal seams stiffening the edge formation for the cuboid shape.
- the packaging containers described show their particular advantages in larger containers, in which the improved degree of filling and the exact cuboid shape is particularly advantageous.
- These containers can be produced with a reduced cost of materials in relation to the volume of packaging, with a very low-loss space transport and store and present especially on the sales presentation effectively on the shelf by placed on a side wall ("landscape") or placed on an end wall ( "Portrait”) turn one main face to the buyer.
- the available presentation space such as the depth of store shelves, can be used by placing the packages one behind the other.
- FIG. 1 An in Fig. 1 Overall, designated by 1 packaging container has (according to the drawing and in practice also approximated) a parallelepiped shape with three pairs of opposite parallelepiped sides, which are typically different from pair to pair are big.
- the packaging container is made of a film material which is sealable at least on the inside, that is, has a sealable plastic material at least on the inside.
- the film material may be uniform overall but also have a layering of plastic or metal materials to meet different packaging requirements in terms of moisture resistance, vapor permeability, aroma resistance, tear strength, among others.
- main walls 2, 3, side walls 4 and end walls 5 are referred to as main walls 2, 3, side walls 4 and end walls 5.
- the main walls 2, 3 and the side walls 4 are each separated by longitudinal edges 6, 7, 8, 9 from each other. These also uniformly represent the longest edges of the cuboid.
- the remaining edges, which bound the end walls 5, are all characterized as transverse edges, in the drawing with 10, 11, 12, 13, 14, 15, 16, even if they could still be divided into two different lengths.
- Fig. 1 are in the side walls 4 and in the end walls 5 still dash-dotted lines 17 partly parallel to the main surfaces 2, 3 and partly obliquely inwardly extending from the corners, indicating only fold lines or folding edges, when the packaging container 1 with V-shaped side walls folded and end walls and plan superimposed main walls flat - ready for despatch - is folded.
- the center lines running parallel to the main surfaces 2, 3 mark the actual fold line.
- the oblique lines indicate that the V-fold in the corner area is performed only from one side to the edge can be, while the folding from the other side is then adapt over triangular folds.
- the illustrated packaging container 1 does not have a middle seam on the whole, as is customary with regard to manufacturing technology in conventional gusseted or bottom gusseted bags, but then also creates unfavorable transitions when merging the main and side surfaces into a single seam for the cuboid shape.
- the pieces of film forming the rectangular walls are connected to one another via sealing seams that run along all the longitudinal and transverse edges.
- the cuboid shape for example, with a piece of film, which forms the main and side surfaces 2, 3, 4 in one piece and which is then joined together only at a longitudinal edge, such as the longitudinal edge 6 to form a tube around the open Then close the hose ends with the end walls 5.
- the manufacturing technology although possibly to be saved seams on the longitudinal edges in the illustrated more complex embodiment, however, also have the advantage that the longitudinal edges are marked and stiffened and thereby the cuboid shape better forms.
- the longitudinal edge 6 is completely or at least largely open by a reclosing 18 whose seal between the main wall 3 and the side wall 4 so far replaced the sealed seam between the walls.
- the arrangement along a longitudinal edge - here longitudinal edge 6 - has the general advantage that a large opening is made possible that the adjacent walls can move apart over a large area at a removal and that in a pouring through the removal opening sliding surfaces are formed with the inner sides of the adjacent walls.
- a handle 19 is arranged approximately centrally on the side wall 4, which allows the handling in particular bulky packaging container.
- the arrangement on the side wall 4 (instead of one of the main walls) leads to a laterally less bulky carrying posture.
- the handle 19 may be configured in a conventional manner, for example according to one of the embodiments in FIG WO 2005 012 122 , wherein it is formed in the present arrangement on one of the fold lines in the middle not only flat but also foldable longitudinally.
- This embodiment comprises a flat grip band 20, which can be gripped under in the middle, which is sealed onto the ends of a support plate 21, which in turn is fastened to the thinner foil of the side wall 4 on a sealing foil 22 to transfer the load.
- the handle does not only serve the transport of the (filled) packaging but also as handling when opening, as in Fig. 2 is illustrated.
- the side surface 4 can be raised with the aid of the handle in order to achieve the filling of the packaging that is accessible when the reclosure 18 is open.
- opening via the handle 19 and removal with a tool (spoon) 23 can be provided.
- the reclosure 18 is a "slider" closure commonly used in film packaging, ie a closure which is available in prefabricated form and has two profile strips which are to be locked into one another lengthwise, wherein the latching by a slide (slider) 18a is additionally facilitated.
- the moldings are provided in a known manner with connection lugs made of plastic (not shown), with the aid of which they can be sealed in a foil packaging as here and which are also connected to each other.
- connection of the terminal lugs is ruptured or cut open in a conventional manner, so that then a Clearö réelle the packaging container is also recognizable.
- An alternative solution according to the invention for separating the reclosing strips or connecting lugs is to form the connection in the form of a wind-up (“peelable”) strip, so that a tool is not required in this case.
- the packaging container 1 has the particularly exact cuboid shape advantages in terms of the most extensive use of transport, storage and presentation space. He can, for example, in the in Fig. 1 shown location with top handle and a directly to be considered main surface (with the desired packaging design) are placed in a store shelf and then conceal the use of shelf depth also parallel behind it further packaging same type.
- FIG. 3 a further packaging container 24 is shown in the folded state, which shows a main wall 25 with a longitudinal edge 26 and a reclosure 27 at this longitudinal edge.
- a filling opening 28 is at the top, over the actual main wall 25 protruding, formed with a connecting piece 29.
- the design of the packaging container 24 in the unfolded state shows Fig. 4 , wherein a side wall 30 and an end wall 31 has unfolded adjacent to the main wall 25.
- the over the actual main wall 25 and the end wall 31 upwardly projecting nozzle is formed by a supernatant of the film material of the main wall on the one hand and a supernatant of the film material of the end wall 31 on the other hand, both are sealed together in the extension of the longitudinal edges and thus one over the entire width the main wall 25 extended fill opening 28 offer.
- a convenient and complete filling of the packaging container 24 is well possible with free-flowing material, wherein the packaging container to be filled 24 can also be inclined in a manner that the end wall 31 from the nozzle 29 away obliquely and is completely underfilled during filling , After filling, the nozzle part 29 is to be separated, for example, with a sealing seam, wherein the filling opening 28 is then also closed.
- FIGS. 5 and 6 is a packaging container 32 in a slight modification to the packaging container 24 in a folded form ( Fig. 5 ) or in unfolded form ( Fig. 6
- a reclosure 37 is arranged on a longitudinal edge, while the filling opening 35 is not approximately, as is often the case with conventional side pleated bags with reclosure , is provided directly on the reclosure but on another surface or edge.
- the filling opening 28 is placed in the packaging container 24 in a transverse edge, the filling opening 35 together with the filler neck 36 in the embodiment of the packaging container 32 after FIGS. 5 and 6 placed in the middle of the end wall 34.
- the filler neck is made by projecting film material of the adjacent wall, so here the end wall 34, wherein the end wall is composed of two halves, between which the supernatant film is merged and sealed together edge.

Description
Die Erfindung betrifft einen Verpackungsbehälter nach dem Oberbegriff des Anspruchs 1.The invention relates to a packaging container according to the preamble of
Verpackungsbehälter dieser Art sind in Form von Seitenfaltenbeuteln oder Bodenfaltenbeuteln weit verbreitet und bieten nicht nur einen nach Raum, Volumen und Kosten geringen Verpackungsaufwand sondern lassen sich auch in durchentwickelten Maschinendurchläufen effektiv fertigen, befüllen und verschließen. Eine für die Lagerung, den Versandt und die Warenrepräsentation regelmäßig gewünschte Quaderform der (befüllten) Verpackung lässt sich bei den üblichen herkömmlichen Verpackungen allerdings nur angenährt herstellen, da sie eine schwer zu erreichende vollständige Befüllung voraussetzt und da bei rieselfähigen Verpackungsgütern Verformungen insgesamt leicht auftreten. Wenn dann in der herkömmlichen Weise die Verpackungen an einem (Kopf-)Ende zu einer Entnahmeöffnung zusammengeführt werden, bei der ggf. auch Seitenfalten zusammenlaufen und evtl. auch am anderen Ende eine mittige Boden-Quernaht den Abschluss bildet, neigen Verpackungen mit einer unvollkommenen Befüllung zu variablen Formen. Die Aufstellbarkeit der Verpackungen ist dabei ungewiss. Überdies sind Verpackungen über eine mit einem Wiederverschluss versehene Entnahmeöffnung schlecht zugänglich, soweit der Entnahmeschlitz kurz ist und ggf. noch durch Seitenfalten im Kopfabschluss beeinträchtigt wird.Packaging containers of this kind are widely used in the form of side-folding bags or bottom-folding bags and not only offer a packaging expenditure that is small in terms of space, volume and costs but can also be effectively manufactured, filled and sealed in well-developed machine throughputs. However, a rectangular shape of the (filled) packaging which is regularly desired for storage, shipping and product representation can only be produced in a nutshell in conventional conventional packaging since it requires a complete filling that is difficult to achieve and because deformations generally occur easily with free-flowing packaged goods. Then, if in the conventional manner, the packages are brought together at one (head) end to a removal opening, where possibly also gussets converge and possibly at the other end a central bottom cross seam forms the conclusion, packaging tend to incomplete filling to variable forms. The installation of the packaging is uncertain. Moreover, packages are poorly accessible via a removal opening provided with a reclosure, as far as the withdrawal slot is short and possibly even affected by gussets in the head ending.
Verpackungsbehälter der vorbetrachteten Art mit im Wesentlichen quaderförmig ausfaltbaren, allerdings in Zwickeln endenden Seitenfaltenwänden zwischen Hauptwänden, die an einander gegenüberliegenden Enden zu einer Mittelnaht oder Leiste, insbesondere als Bodennaht bzw.

Aufgabe der Erfindung ist es, einen Verpackungsbehälter zu schaffen, der bei stückigem oder rieselförmigem Gut einen besseren Befüllungsgrad ermöglicht, sich dabei an die gewünschte Quaderform besser annährt, der damit auch gut auf Seiten- oder Stirnwände aufstellbar ist und der eine möglichst weite und bequem zugängliche Entnahmeöffnung mit einem Wiederverschluss ermöglicht.The object of the invention is to provide a packaging container, which allows a better degree of filling with lumpy or free-flowing material, it better feeds to the desired parallelepiped shape, which is thus well set up on side or end walls and the widest and easily accessible Removal opening with a reclosure allows.
Die Aufgabe wird von einem Verpackungsbehälter gemäß dem Oberbegriff des Anspruchs 1 mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst.The object is achieved by a packaging container according to the preamble of
Ein wesentlicher Schritt zur Lösung dieser Aufgabenstellung besteht gemäß der Erfindung darin, dass die Entnahmeöffnung längs einer der Längskanten verläuft. Dabei wird die herkömmlich in einem fertigungstechnisch im Kopfabschluss eines Verpackungsbehälters angeordnete Entnahmeöffnung an eine der Längskanten verlegt, die schon von der Kantenlänge her eine größere bzw. längere Einfüllöffnung / Entnahmeöffnung ermöglichen, die dementsprechend auch weiter und bequemer zu öffnen ist. Dieser Bereich des Verpackungsbehälters ist aber auch ohne Weiteres von der Einbindung bzw. einem Abschluss von Seitenfaltenwänden herkömmlicher Art freizuhalten und insofern ohne Weiteres ungestört zu durchgreifen. Insbesondere die Verlagerung der Entnahmeöffnung zur Seitenkante hin und von einer Anordnung aus einem mittleren Bereich der Behälterwände weg führt dazu, dass die benachbarten Wände des Behälters im Wesentlichen flach beim Öffnen aufgebogen werden und dementsprechend wenig sperrig sind. Dies gilt auch dann, wenn der Verpackungsbehälter in einer Quaderform mit nicht sehr verschiedenen Kantenlängen etwa stärker an eine Kubusform angenährt sein sollte. Die sich mit der Verlegung der Entnahmeöffnung zu einer Seitenkante ergebende freiere Gestaltungsmöglichkeit einer Stirnwand im früheren Kopfbereich ermöglicht aber auch eine bessere Befüllung des Verpackungsbehälters mit Vorteil für die exaktere Quaderform und die Aufstellbarkeit auf eine Seiten- oder Stirnwand.An essential step in the solution of this task is according to the invention in that the removal opening extends along one of the longitudinal edges. there The conventionally arranged in a production technology in the head of a packaging container removal opening is moved to one of the longitudinal edges, which allow even from the edge length ago a larger or longer filling opening / removal opening, which is accordingly wider and more convenient to open. However, this area of the packaging container is also readily to be kept free from the integration or completion of side gusseted walls of a conventional type and, in this respect, can easily be accessed undisturbed. In particular, the displacement of the removal opening towards the side edge and away from an arrangement from a central region of the container walls results in that the adjacent walls of the container are bent up substantially flat when opened and accordingly are not very bulky. This is true even if the packaging container in a parallelepiped shape with not very different edge lengths should be more closely approximated to a cube shape. However, the freer design possibility of an end wall in the former head area resulting with the removal of the removal opening to a side edge also enables a better filling of the packaging container with advantage for the exact cuboid shape and the installation on a side or end wall.
Die dabei "längs" einer Längskante verlaufende Entnahmeöffnung beraucht hierzu nicht exakt symmetrisch auf die Längskante gelegt zu sein, vielmehr kann die Bauform des Wiederverschlusses dazu führen, dass dieser direkt angrenzend in die eine oder andere (Haupt- oder Seiten-)Wand gelegt wird.For this purpose, the removal opening running "along" a longitudinal edge does not have to be placed exactly symmetrically on the longitudinal edge; rather, the design of the reclosure can lead to it being placed directly adjacent to one or the other (main or side) wall.
Vorzugsweise ist der Wiederverschluss mit zwei Wiederverschlussleisten gebildet, die eine bei der Erstöffnung irreversibel aufzutrennende Verbindung aufweisen. Dieses hat den im Vertrieb von Verpackungen breithin und auch mit handelsüblichen Wiederverschlüssen angebotene Vorteil der "Neuheitsgarantie" im Verkauf und der Unversehrtheit der Anlieferung. Darüber hinaus sind Wiederverschlussleisten in dieser Weise gegenüber einem Aufbrechen bei besonderen Beanspruchungen des Verpackungsbehälters in Versand und Vertrieb zusätzlich abzusichern. Wiederverschlüsse etwa mit zwei Wiederverschlussleisten, die mit verrastenden Profilstreifen, ggf. auch einem längsbeweglichen Schieber, zu schließen oder zu öffnen sind, lassen sich durch eine auftrennbare Verbindung zwischen den Wiederverschlussleisten sichern und abdichten. Bis zur Erstöffnung können aber auch Wiederverschlussleisten über einen peelbaren (abziehbaren) Folien-Steg miteinander verbunden werden, der eine werkzeuglose Erstöffnung ermöglicht.Preferably, the reclosure is formed with two reclosure strips, which have an irreversible in the first opening aufzutrennende connection. This has the advantage offered in the distribution of packaging breithin and also with commercial reclosures the "novelty guarantee" in the sale and the integrity of the delivery. In addition, reclosing strips are in this way against breakage in case of special stresses of the packaging container in shipping and distribution additionally secure. Reclosures with, for example, two reclosing strips which can be closed or opened with latching profile strips, if necessary also a longitudinally movable slide, can be secured and sealed by a separable connection between the reclosure strips. But until the first opening reclosure strips can be connected to each other via a peelable (removable) film web, which allows a tool-free initial opening.
Der leere und damit erst noch zu befüllende Verpackungsbeutel kann zweckmäßig mit einer weiten Einfüllöffnung versehen werden, die nach dem Befüllen verschlossen wird, wobei gemäß der Erfindung diese Einfüllöffnung nicht in herkömmlicher Weise direkt neben die Entnahmeöffnung und angrenzend an den Wiederverschluss gelegt ist sondern besser längs einer der anderen Längskanten oder in einer der Querkanten verläuft. Damit kann die erst nach dem Befüllen etwa mit einer Siegelnaht zu schließende Einfüllöffnung unabhängig von der Entnahmeöffnung und deren Wiederverschluss weit und gut zugänglich ausgebildet sein. Dies erlaubt nicht nur ein bequemes Befüllen sondern auch einen hohen Befüllungsgrad, der sich bis auf ein Restvolumen von deutlich unter 5 % statt herkömmlicher 10 % bis 15 % verbessern lässt. Je nach den Gegebenheiten der maschinellen Befüllung kann es von Vorteil sein, die Einfüllöffnung zunächst mit einem vorstehenden Einfüllstutzen auszubilden, der nach dem Befüllen bequem mit einer Trenn-Siegelnaht zu verschließen und abzutrennen ist. Ein solcher Einfüllstutzen kann beispielsweise durch überstehende Folienbereiche aus den angrenzenden Wänden gebildet werden, die als aneinander liegende Streifen herausgezogen und randseitig miteinander zu einer Schlauchform verbunden sind.The empty and so still to be filled packaging bag can be conveniently provided with a wide filling opening, which is closed after filling, according to the invention, this filling opening is not placed in a conventional manner directly adjacent to the removal opening and adjacent to the reclosure but better along a the other longitudinal edges or in one of the transverse edges runs. Thus, the filling opening to be closed only after filling, for example with a sealed seam, can be designed to be wide and easily accessible independently of the removal opening and its reclosure. This allows not only a convenient filling but also a high degree of filling, which improve to a residual volume of well below 5% instead of the conventional 10% to 15% leaves. Depending on the circumstances of the machine filling, it may be advantageous to initially form the filling opening with a protruding filler neck, which is easy to close and separate after filling with a separating sealing seam. Such a filler neck can be formed for example by projecting film areas from the adjacent walls, which are pulled out as strips lying adjacent to each other and are connected to one another at the edges to form a tube.
Insbesondere soweit Verpackungsbehälter der hier betrachteten Art großvolumig über ein "handliches" Maß hinausgehen, können diese zweckmäßig mit zumindest einem Griff versehen werden, der vorteilhaft mit dem Verpackungsbehälter flach zusammenlegbar ist. Ein solcher Griff ist nicht nur für die käuferseitige Handhabung beim Heimtransport eines befüllten Verpackungsbehälters von Vorteil sondern auch beim Öffnen, um dabei über den Griff eine Seite der Entnahmeöffnung aufzuziehen. Der Griff kann ein aus Folie gebildeter Streifen sein, der auf einer der Wände flach aufliegend befestigt ist. Zum Aufziehen kann er mit einem vorgegebenen Abstand vom Wiederverschluss auf einer der Wände angeordnet sein.In particular, as far as packaging containers of the type considered here exceed a "manageable" measure, they can expediently be provided with at least one handle, which can advantageously be folded flat with the packaging container. Such a handle is not only for the buyer-side handling when home transport a filled packaging container advantage but also when opening to raise it on the handle one side of the removal opening. The handle may be a film-formed strip attached flat to one of the walls. For mounting, it can be arranged at a predetermined distance from the reclosure on one of the walls.
Um die herkömmlich zwar einfach herzustellende aber insbesondere für den befüllten Zustand nachteilige Formgebung durch mittlere Querversiegelungen bzw. Quernähte am Kopf und ggf. auch am Boden zu vermeiden, kann dieser eine streng geometrische Formgebung erhalten, bei der die Siegelnähte insgesamt nur an den Kanten zwischen den Wänden verlaufen. Dieses liefert eine von Haus aus vorgegebene und nicht erst durch eine passende und vollständige Befüllung zu erzielende Quaderform. Dabei wird vorzugsweise eine Schlauchform, etwa durch eine schlauchförmig extrudierte Blasfolie, allgemeiner aber noch eine Schlauchform aus einer mit einer Längsnaht zum Schlauch geformten Flachfolie hergestellt, deren offene Endquerschnitte in gegenseitigem Abstand entsprechend der Quaderform liegen und durch Stirnwände über allseitige Randnähte geschlossen werden.In order to avoid the conventionally simple but especially for the filled state disadvantageous shaping by means of transverse transverse seals or cross seams on the head and possibly also on the ground, this can get a strictly geometric shape, in which the seal seams total only at the edges between the Walls are lost. This provides an inherently given and not to be achieved only by a suitable and complete filling Cuboid shape. In this case, preferably a tubular shape, such as a tubular extruded blown film, but more generally a tubular shape made of a flat seam formed with a longitudinal seam to the tube, the open end cross-sections are at a mutual distance corresponding to the cuboid shape and closed by end walls on all sides edge seams.
Dabei kann die Längsnaht für den Schlauch vorteilhaft in die Kante gelegt sein. Die Schlauchform kann aber auch dadurch erzielt werden, dass die einzelnen Wände, etwa die Haupt- und Seitenwände, durch vier die Längskanten bildende Seitennähte miteinander versiegelt werden, wobei die Längsnähte versteifend zur Kantenbildung für die Quaderform beitragen.The longitudinal seam for the hose can advantageously be laid in the edge. However, the tubular shape can also be achieved by sealing the individual walls, such as the main and side walls, by four side seams forming the longitudinal edges, the longitudinal seams stiffening the edge formation for the cuboid shape.
Die beschriebenen Verpackungsbehälter zeigen ihre besonderen Vorteile bei größeren Gebinden, bei denen der verbesserte Befüllungsgrad und die exaktere Quaderform besonders vorteilhaft zum Tragen kommt. Diese Gebinde lassen sich mit verringertem Materialaufwand in Bezug auf das Verpackungsvolumen herstellen, mit einem sehr verlustarmen Raumaufwand transportieren und lagern und vor allem bei der Verkaufspräsentation wirkungsvoll im Verkaufsregal präsentieren, indem sie auf eine Seitenwand aufgestellt ("Querformat") oder auf eine Stirnwand aufgestellt ("Hochformat") eine Hauptfläche dem Käufer zuwenden. Der zur Verfügung stehende Präsentationsraum, etwa die Tiefe von Verkaufsregalen, kann dadurch genutzt werden, dass die Verpackungen hintereinander stehen.The packaging containers described show their particular advantages in larger containers, in which the improved degree of filling and the exact cuboid shape is particularly advantageous. These containers can be produced with a reduced cost of materials in relation to the volume of packaging, with a very low-loss space transport and store and present especially on the sales presentation effectively on the shelf by placed on a side wall ("landscape") or placed on an end wall ( "Portrait") turn one main face to the buyer. The available presentation space, such as the depth of store shelves, can be used by placing the packages one behind the other.

Der Größe nach seien die sich zur Quaderform zusammenfügenden Wände als Hauptwände 2, 3, Seitenwände 4 und Stirnwände 5 bezeichnet. Die Hauptwände 2, 3 und die Seitenwände 4 sind jeweils durch Längskanten 6, 7, 8, 9 voneinander abzugrenzen. Diese stellen auch einheitlich die längsten Kanten des Quaders da. Die übrigen Kanten, die die Stirnwände 5 umgrenzen, sind allesamt als Querkanten, in der Zeichnung mit 10, 11, 12, 13, 14, 15, 16 gekennzeichnet, auch wenn diese sich noch in zwei verschiedene Längen unterteilen ließen.In terms of size, the walls joining together to form a cuboid are referred to as

Der dargestellte Verpackungsbehälter 1 weist allerdings insgesamt keine Mittelnaht auf, wie sie fertigungstechnisch bedingt bei herkömmlichen Seitenfalten- oder Bodenfaltenbeuteln üblich ist, allerdings dann auch beim Zusammenführen der Haupt- und Seitenflächen zu einer einzigen Naht für die Quaderform ungünstige Übergänge schafft. Hier sind die die rechteckigen Wände bildenden Folienstücke über Siegelnähte miteinander verbunden, die längs allen Längs- und Querkanten verlaufen.However, the illustrated
Es versteht sich zwar, dass die Quaderform auch beispielsweise mit einem Folienstück, welches die Haupt- und Seitenflächen 2, 3, 4 in einem Stück bildet und welches nur an einer Längskante, etwa der Längskante 6 dann zu einer Schlauchform zusammengeschlossen wird, um die offenen Schlauchenden danach mit den Stirnwänden 5 zu schließen. Die dabei fertigungstechnisch zwar ggf. einzusparenden Nähte an den Längskanten haben bei der dargestellten aufwendigeren Ausführungsform allerdings auch den Vorteil, dass die Längskanten markiert und versteift sind und sich dadurch die Quaderform besser herausbildet.Although it is understood that the cuboid shape, for example, with a piece of film, which forms the main and
Die Längskante 6 ist vollständig oder zumindest weitgehend durch einen Wiederverschluss 18 zu öffnen, dessen Einsiegelung zwischen die Hauptwand 3 und die Seitenwand 4 insoweit die Siegelnaht zwischen den Wänden ersetzt. Die Anordnung längs einer Längskante - hier Längskante 6 - hat den generellen Vorteil, dass eine große Öffnung ermöglicht ist, dass sich die benachbarten Wände bei einer Entnahme großflächig auseinander bewegen lassen und dass bei einem Ausschütten durch die Entnahmeöffnung Gleitflächen mit den Innenseiten der benachbarten Wände gebildet sind.The longitudinal edge 6 is completely or at least largely open by a reclosing 18 whose seal between the
Weiterhin ist ein Griff 19 etwa mittig auf der Seitenwand 4 angeordnet, der die Handhabung insbesondere großvolumiger Verpackungsbehälter ermöglicht. Die Anordnung auf der Seitenwand 4 (statt einer der Hauptwände) führt zu einer seitlich weniger ausladenden Tragehaltung. Der Griff 19 kann in herkömmlicher Weise ausgestaltet sein, beispielsweise gemäß einer der Ausführungsformen in der
Der Wiederverschluss 18 ist im vorliegenden Fall eine bei Folienverpackungen gebräuchlicher "Slider"-Verschluss, also ein in vorgefertigter Form erhältlicher Verschluss mit zwei Profilstreifen, die der Länge nach ineinander zu verrasten sind, wobei das Verrasten durch einen Schieber (Slider) 18a zusätzlich erleichtert wird. Die Profilleisten sind in bekannter Weise mit Anschlussfahnen aus Kunststoff (nicht dargestellt) versehen, mit Hilfe derer sie in eine Folienverpackung wie hier eingesiegelt werden können und die auch miteinander verbunden sind. Damit ist der Wiederverschluss geschlossen, unabhängig von einer etwaigen Verschiebung des Schiebers 18a und sichert die Dichtigkeit des Verpackungsbehältnisses 1 auch beispielsweise gegenüber Beanspruchungen des Verpackungsbehältnisses gefüllten Zustand beim Transport.In the present case, the
Die Verbindung der Anschlussfahnen ist in herkömmlicher Weise aufzureißen oder aufzuschneiden, so dass dann eine Erstöffnung des Verpackungsbehältnisses auch erkennbar wird. Eine erfindungsgemäße alternative Lösung für eine Trennung der Wiederverschlussleisten bzw. Anschlussfahnen besteht darin, die Verbindung in Form eines aufziehbaren ("peelfähigen") Streifens auszubilden, so dass ein Werkzeug dabei nicht benötigt wird.The connection of the terminal lugs is ruptured or cut open in a conventional manner, so that then a Erstöffnung the packaging container is also recognizable. An alternative solution according to the invention for separating the reclosing strips or connecting lugs is to form the connection in the form of a wind-up ("peelable") strip, so that a tool is not required in this case.
Der Verpackungsbehälter 1 hat mit der besonders exakten Quaderform Vorteile hinsichtlich der weitestgehenden Nutzung von Transport-, Lager- und Präsentationsraum. Er kann beispielsweise in der in
Für die exakte Quaderform ist eine hochgradige Befüllung von Interesse, die gleichzeitig aber auch wieder für eine minimierte Verpackung bei einer vorgegebenen zu verpackenden Produktmenge sorgt. Für die Befüllung sind vorteilhafte Einfüllöffnungen vorzusehen, die zur schnellen maschinellen Befüllung groß genug sein sollen und die zu allen Ecken des Verpackungsbehältnisses Zugang erhält.For the exact cuboid shape is a high-grade filling of interest, but at the same time but again ensures a minimized packaging for a given packaged amount of product. For the filling advantageous fill openings are provided, which should be large enough for fast machine filling and access to all corners of the packaging container access.
