Description

Die Erfindung betrifft einen Sack, gebildet aus einer zu einem Schlauch mittels einer Längsklebenaht verbundenen Mantelwandung, die an wenigstens einem Ende zu einem im gefüllten Zustand eine rechteckige Form annehmenden Boden gefaltet ist, in dem Bodenklappen von langen Seitenkanten des Bodens gegeneinander und über von kurzen Seitenkanten ausgehenden Eckeinschlägen gefaltet und mittels eines aufgeklebten Bodendeckblatts überdeckt sind, wobei der Boden zur Bildung einer Ausschüttöffnung durch Freilegen und Herausstülpen eines Eckeinschlags vorgesehen ist.The invention relates to a bag formed from a jacket wall connected to a tube by means of a longitudinal adhesive seam folded at at least one end into a filled rectangular bottom, in the bottom flaps from long side edges of the bottom against each other and over short side edges outgoing corner fences are folded and covered by a glued bottom cover sheet, wherein the bottom is provided for forming a discharge opening by exposing and stucking out a corner impact.

Die Erfindung betrifft insbesondere einen Sack mit einem Kreuzboden. Die Erfindung betrifft ferner einen Sack, dessen Mantelwandung zumindest überwiegend aus Papier, insbesondere Kraftpapier besteht, das ein- oder mehrlagig ausgebildet ist. Dabei kann eine Lage der Sackwandung auch aus einem Kunststoff, vorzugsweise recycelbaren Kunststoff, bestehen, um eine Dampfsperre zu bilden, die die Beständigkeit des Sackes gegen Feuchte erhöht usw.The invention particularly relates to a bag with a cross bottom. The invention further relates to a bag whose jacket wall consists at least predominantly of paper, in particular kraft paper, which is formed in one or more layers. In this case, a position of the bag wall also made of a plastic, preferably recyclable plastic, exist to form a vapor barrier, which increases the resistance of the bag to moisture, etc.

Derartige Säcke kommen in zahlreichen Ausführungsformen zum Einsatz. Es ist bekannt, einen Sack mit einem Boden der genannten Art oben offen auszubilden, sodass die Befüllung des Sacks über das offene Ende des aus der Mantelwandung gebildeten Schlauchs erfolgen kann. Nach dem Befüllen kann das obere Ende in üblicher Weise verschlossen werden, beispielsweise durch Nähen, Kleben, Verschweißen o. ä.Such bags are used in numerous embodiments. It is known to form a bag with a bottom of the type mentioned above open, so that the filling of the bag can take place via the open end of the tube formed from the jacket wall. After filling, the upper end can be closed in a conventional manner, for example by sewing, gluing, welding o. Ä.

Es ist ferner bekannt, einen Sack bereits vor dem Befüllen mit Böden der genannten Art auszubilden und zu verkleben, wobei einer der Böden so verklebt ist, dass sich eine rohrförmige Einfüllöffnung ausbildet, in die ein Ventil, beispielsweise in Form eines Ventilblatts, eingelegt sein kann. Die Befüllung des Sackes erfolgt dann über eine Füllröhre einer Füllmaschine, indem die Füllröhre in die Einfüllöffnung eingeführt wird und die Füllmaschine das zu befüllende Material in das Sackinnere fördert. Nach dem Befüllen wird der Sack üblicherweise über Kopf abgeworfen, sodass er auf dem Boden mit der Einfüllöffnung zu stehen kommt und das Füllmaterial die Einfüllöffnung aufgrund seines Gewichts in die Schließstellung drückt. Bei kritischen Materialien kann die Einfüllöffnung, insbesondere ein dort eingesetztes Ventil auch hermetisch verschlossen werden, beispielsweise durch Verkleben oder Verschweißen.It is also known to form a bag before filling with soils of the type mentioned and stick together, wherein one of the floors so glued is that forms a tubular filling opening, in which a valve, for example in the form of a valve sheet, can be inserted. The filling of the bag is then via a filling tube of a filling machine by the filling tube is inserted into the filling opening and the filling machine promotes the material to be filled into the bag interior. After filling, the bag is usually dropped over the head, so that it comes to rest on the floor with the filling opening and the filling material presses the filling opening due to its weight in the closed position. For critical materials, the filling opening, in particular a valve used there, can also be hermetically sealed, for example by gluing or welding.

Insbesondere wenn die Sackwandung aus einem stabilen Material, beispielsweise aus mehreren Lagen Kraftpapier, gebildet ist, stellt das Öffnen des Sacks ein Handhabungsproblem dar. Ein übliches Verfahren, einen verschlossenen Sack zu öffnen, besteht in der Verwendung eines Messers, mit dem beim auf einem Boden stehenden Sack die Sackwandung rundum eingeschnitten wird, um so unterhalb des oberen Endes den Verschluss des Sackes zu entfernen und so einen oben offenen Sack auszubilden, aus dem das Füllmaterial ausgeschüttet werden kann. Insbesondere bei staubenden Füllmaterialien lässt es sich nicht vermeiden, dass Füllmaterial an der Öffnungsstelle in die Umgebung gelangt und so eine Verschmutzung darstellt.In particular, when the bag wall is formed of a stable material, such as multiple layers of kraft paper, opening the bag is a handling problem. One common method of opening a closed bag is to use a knife with the same when standing on a floor standing bag the bag wall is cut all around, so as to remove below the upper end of the closure of the bag and so form an open-topped bag, from which the filling material can be distributed. In particular with dusty filling materials, it is unavoidable that filling material enters the environment at the opening point and thus constitutes soiling.

Es ist ferner bekannt, den Boden in geeigneter Weise im Bereich eines Eckeinschlags zu öffnen und den Eckeinschlag nach außen bzw. oben zu ziehen, sodass der Eckeinschlag zusammen mit der benachbarten Sackwandung, also dem benachbarten Ende der Bodenklappen eine Ausschütttülle bildet, mit der das schüttfähige Füllmaterial aus dem Sack auskippbar ist. Es ist bekannt, hierfür Einschnitte in den Bodenklappen vorzusehen, die das Freilegen des Eckeinschlags durch Einreißen der Bodenklappen senkrecht zur langen Seitenkante ermöglichen, sodass anschließend der Eckeinschlag nach außen zur Bildung einer Ausschüttrinne gestülpt werden kann. Ist der Sack entleert worden, wird er entsorgt. Eine weitere Verwendungsmöglichkeit besteht nicht.It is also known to open the floor in a suitable manner in the area of a corner impact and to pull the corner impact outwards or upwards, so that the corner impact together with the adjacent bag wall, so the adjacent end of the bottom flaps forms a Ausschütttülle, with the pourable Filling material can be tilted out of the bag. It is known to provide for this cuts in the bottom flaps, which allow the exposure of the corner impact by tearing the bottom flaps perpendicular to the long side edge, so that then the corner impact can be slipped out to form a discharge chute. Has the bag been emptied, he is disposed of. Another use is not.

Der vorliegenden Erfindung liegt die Problemstellung zugrunde, einen Sack der beschriebenen Art in seiner Handhabung zu verbessern und in seiner Verwendungsmöglichkeit zu erweitern.The present invention is based on the problem to improve a bag of the type described in its handling and to expand its use.

Zur Lösung dieser Aufgabe ist erfindungsgemäß ein Sack der eingangs erwähnten Art dadurch gekennzeichnet, dass das Bodendeckblatt mit einer parallel zu den langen Seitenkanten mittig verlaufenden und sich über den Eckeinschlag erstreckenden Öffnungslinie versehen ist, dass sich ein Traggriff mittig über den Boden erstreckt und dass der Traggriff von seinem zum Eckeinschlag zeigenden Ende ausgehend mit einer Trennlinie zur Teilung des Traggriffs in zwei Teilgriffe versehen ist.To solve this problem, a bag of the type mentioned is characterized in that the ground cover sheet is provided with a parallel to the long side edges extending centrally and extending over the corner hemming opening line that a carrying handle extends centrally above the ground and that the carrying handle starting from its end facing the corner, starting with a dividing line for dividing the carrying handle into two partial handles.

Der erfindungsgemäße Sack sieht somit eine Öffnungslinie des Bodendeckblatts vor, durch deren Öffnung die Bodenklappen im Bereich des Eckeinschlags ergreifbar sind und so, ggf. mit einem Einreißvorgang, auffaltbar sind, dass der Einschlag freigelegt wird und zur Bildung einer Ausschüttrinne nach außen gestülpt werden kann. Erfindungsgemäß ist das Bodendeckblatt mit einem Tragegriff versehen, der mit einer mit der Öffnungslinie fluchtenden Trennlinie ausgebildet ist, um beim Öffnen des Bodendeckblattes entlang der Öffnungslinie auch eine Trennung des Tragegriffs in die Teilgriffe vorzunehmen. Die Ausbildung der Ausschüttöffnung kann sich daher in den Bereich des Tragegriffs hinein erstrecken, wobei der Tragegriff zumindest teilweise in die Teilgriffe getrennt wird. Ist der Sack auf diese Weise kontrolliert entleert worden, steht er als Behältnis, beispielsweise als Sammelbehältnis für Abfälle, zur Verfügung. Nach dem Befüllen mit Abfällen kann der Sack dann an den beiden Teilgriffen gemeinsam ergriffen werden, sodass er bequem gehandhabt werden kann, um Abfälle zusammen mit dem Sack zu entsorgen.The bag according to the invention thus provides an opening line of the bottom cover sheet, through the opening of which the bottom flaps can be grasped in the area of the corner impact and thus, possibly with a tearing process, can be unfolded so that the impact is uncovered and can be slipped outwards to form a discharge channel. According to the ground cover sheet is provided with a carrying handle which is formed with an aligned with the opening line parting line to perform when opening the bottom cover sheet along the opening line and a separation of the handle in the part handles. The formation of the discharge opening can therefore extend into the region of the carrying handle, wherein the carrying handle is at least partially separated into the part handles. If the bag has been emptied controlled in this way, it is available as a container, for example as a collection container for waste available. After filling with waste, the bag can then be gripped together on the two part handles so that it can be handled conveniently to dispose of waste along with the bag.

In einer bevorzugten Ausführungsform der Erfindung wird der Tragegriff aus dem Material des Bodendeckblatts durch Ausstanzen gebildet. Es entfällt daher ein zusätzlicher Aufwand für die Anbringung des Tragegriffs an dem Bodendeckblatt.In a preferred embodiment of the invention, the carrying handle is formed from the material of the bottom cover sheet by punching. It therefore eliminates an additional expense for the attachment of the handle on the ground cover sheet.

Um die Stabilität des Bodendeckblatts auch im Bereich der Öffnungslinie zu gewährleisten, kann es sinnvoll sein, dass die Öffnungslinie mit Unterbrechungen ausgebildet ist, an denen für die Trennung des Materials ein erhöhter Widerstand besteht. Wird gemäß der bevorzugten Ausführungsform der Erfindung der Tragegriff aus dem Material des Bodendeckblatts ausgestanzt weist auch die Trennlinie des Tragegriffs vorzugsweise solche Unterbrechungen auf.In order to ensure the stability of the bottom cover sheet also in the region of the opening line, it may be useful that the opening line is formed with interruptions, at which there is an increased resistance to the separation of the material. If, according to the preferred embodiment of the invention, the carrying handle is punched out of the material of the bottom cover sheet, the dividing line of the carrying handle also preferably has such interruptions.

Die Unterbrechungen der Öffnungslinie des Bodendeckblatts und/oder der Trennlinie des Tragegriffs können durch Gewebe verstärkt werden, das die Öffnungslinie und/oder die Trennlinie überbrückt. Dadurch kann ein unbeabsichtigtes Öffnen der Öffnungslinie und/oder der Trennlinie verhindert werden. Das Gewebe steht vorzugsweise aus Gewebefäden oder Gewebestreifen, die an dem Material des Bodendeckblattes oder des Tragegriffs angebracht oder in das Material eingebracht sind. Die Verstärkung des Bodendeckblatts durch Gewebefäden oder Gewebestreifen kann an geeigneten Stellen des Bodendeckblatts vereinzelt vorgesehen sein. Bevorzugt ist jedoch, dass das Bodendeckblatt in seiner Gesamtheit, also vollflächig, aus einem mit einer Gewebeeinlage, vorzugsweise aus Polypropylenfasern, verstärkten Papierblatt gebildet ist. Das Gewebe weist dabei vorzugsweise Längs- und Querfäden auf, die parallel zu den Kanten des Bodendeckblatts verlaufen. Die Einschnitte des Bodendeckblatts dienen dabei insbesondere zum Durchschneiden der quer - also parallel zu den kurzen Kanten des Bodendeckblatts - verlaufenden Gewebefäden (Querfäden).The interruptions of the opening line of the bottom cover sheet and / or the dividing line of the carrying handle can be reinforced by tissue bridging the opening line and / or the parting line. This can prevent inadvertent opening of the opening line and / or the parting line. The fabric is preferably made of fabric threads or fabric strips which are attached to the material of the bottom cover sheet or the carrying handle or incorporated in the material. The reinforcement of the bottom cover sheet by fabric threads or fabric strips may be provided isolated at suitable locations of the bottom cover sheet. However, it is preferred that the ground cover sheet is formed in its entirety, that is to say over its entire surface, from a paper sheet reinforced with a fabric insert, preferably polypropylene fibers. The fabric preferably has longitudinal and transverse threads which run parallel to the edges of the bottom cover sheet. The incisions of the bottom cover sheet serve in particular for cutting through the transverse - ie parallel to the short edges of the bottom cover sheet - extending fabric threads (transverse threads).

Zur Erhaltung der Stabilität und zur Erleichterung der Handhabung des entleerten Sacks ist es sinnvoll, wenn sich die Öffnungslinie des Bodendeckblatts nicht über die gesamte Länge des Bodendeckblatts erstreckt, sodass an dem der gebildeten Ausschüttöffnung gegenüberliegenden Ende des Bodens das Bodendeckblatt einheitlich ohne Materialtrennung verbleibt. Eine derartige Ausbildung kann auch für die Teilung des Tragegriffs vorgesehen sein, indem sich die Trennlinie nicht über die gesamte Länge des Tragegriffs erstreckt.To maintain the stability and to facilitate the handling of the empty bag, it makes sense when the opening line of the bottom cover sheet does not extend over the entire length of the bottom cover sheet, so that at the end of the bottom opposite the formed discharge opening the bottom cover sheet remains uniformly without material separation. Such a design can also be provided for the division of the carrying handle, in that the dividing line does not extend over the entire length of the carrying handle.

Es ist bevorzugt, dass die erfindungsgemäße Ausbildung des Bodens zur Bildung einer Ausschüttöffnung an einem Boden des Sacks realisiert wird, der sich an dem Ende der Sackwandung befindet, an dem die Einfüllöffnung nicht ausgebildet ist.It is preferred that the inventive construction of the bottom is realized to form a discharge opening at a bottom of the bag, which is located at the end of the bag wall, on which the filling opening is not formed.

Die Erfindung soll im Folgenden anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert werden. Es zeigen:

The invention will be explained in more detail below with reference to an embodiment shown in the drawing. Show it:
FIG. 1
a perspective view of a closed bag with an opening line provided with ground cover sheet, which also forms a dividing line for a carrying handle;
FIG. 2

Die perspektivische Darstellung der Figur 1 lässt einen Sack erkennen, der aus einer schlauchförmigen Mantelwandung 1 gebildet ist, die an einem ersten Ende 2 mit einem (nicht dargestellten) Boden mit einer Einfüllöffnung verschlossen ist und am gegenüberliegenden Ende 3 einen Boden 4 bildet, der im gefüllten Zustand des Sacks rechteckig ist. Der Boden 4 weist somit zwei lange Seitenkanten 5 und zwei kurze Seitenkanten 6 auf. Der Boden 4 ist in üblicher Weise mit einem Bodendeckblatt 7 abgedeckt, das mit einem geeigneten Klebstreifenmuster auf den darunterliegenden Bodenklappen und Eckeinschlägen (nicht dargestellt) aufgeklebt ist.The perspective view of FIG. 1 allows to recognize a bag which is formed from a tubular jacket wall 1, which is closed at a first end 2 with a bottom (not shown) with a filling opening and at the opposite end 3 forms a bottom 4, which is rectangular in the filled state of the bag , The bottom 4 thus has two long side edges 5 and two short side edges 6. The bottom 4 is covered in the usual way with a bottom cover sheet 7, which is glued with a suitable adhesive tape pattern on the underlying bottom flaps and Eckeinschlägen (not shown).

Die Zeichnung lässt eine mittige Öffnungslinie 8 des Bodendeckblatts 7 erkennen, die sich von einer kurzen Seitenkante 9 des Bodendeckblatts 7 ausgehend über die Länge des Bodendeckblatts 7 erstreckt, jedoch mit Abstand vor der gegenüberliegenden kurzen Seitenkante 9' des Bodendeckblatts 7 endet. Parallel zur Öffnungslinie 8 erstrecken sich zwei Einschnitte 10 über eine Teillänge des Bodendeckblatts 7, durch die ein Tragegriff 11 aus dem Material des Bodendeckblatts 7 freigestanzt ist. Im Bereich des Tragegriffs 11 und zur kurzen Seitenkante 9 befinden sich Unterbrechungen 12 der Öffnungslinie 8, durch die das Öffnen der Öffnungslinie zunächst unterbunden wird. In dem dargestellten Ausführungsbeispiel sind die Unterbrechungen durch in das Material des Bodendeckblatts 7 eingebrachte Gewebefäden ausgebildet. Besteht das Bodendeckblatt 7 aus einem durchgehend mit Gewebe verstärkten Papierblatt, müssen für die Unterbrechung der die Öffnungslinie 8 bildenden Einschnitte naturgemäß keine Gewebefäden eingebracht werden, weil diese in dem Bodendeckblatt 7 bereits vorhanden sind.The drawing reveals a central opening line 8 of the bottom cover sheet 7, which extends from a short side edge 9 of the bottom cover sheet 7 over the length of the bottom cover sheet 7, but at a distance the opposite short side edge 9 'of the bottom cover sheet 7 ends. Parallel to the opening line 8, two incisions 10 extend over a partial length of the bottom cover sheet 7, through which a carrying handle 11 is punched free of the material of the bottom cover sheet 7. In the region of the carrying handle 11 and the short side edge 9 there are interruptions 12 of the opening line 8, by which the opening of the opening line is initially prevented. In the illustrated embodiment, the interruptions are formed by introduced into the material of the bottom cover sheet 7 fabric threads. If the bottom cover sheet 7 consists of a continuous paper-reinforced paper sheet, it is not necessary to introduce fabric threads for the interruption of the cuts forming the opening line 8, because these are already present in the bottom cover sheet 7.

Im Bereich des Tragegriffs 11 bildet die Öffnungslinie 8 in dem dargestellten Ausführungsbeispiel zugleich eine Trennlinie 8' für den Tragegriff 11, mit dem dieser in zwei Teilgriffe 13 teilbar ist.In the region of the carrying handle 11, the opening line 8 forms in the illustrated embodiment at the same time a dividing line 8 'for the carrying handle 11, with which this is divisible into two partial grips 13.

In dem Bodendeckblatt sind in Verlängerung der Einschnitte 10 nahe der kurzen Seitenkante 9 zwei kurze Hilfseinschnitte 17 vorgesehen. An der gegenüberliegenden kurzen Seitenkante 9' befindet sich in Verlängerung der Öffnungslinie 8 ein weiteres Einschnittstück 18, das sich bis zur kurzen Seitenkante 9' erstrecken kann, während die Hilfseinschnitte 17 mit Abstand von der kurzen Seitenkante 9 enden.In the ground cover sheet, two short auxiliary cuts 17 are provided in extension of the incisions 10 near the short side edge 9. On the opposite short side edge 9 'is located in extension of the opening line 8, a further incision piece 18, which can extend to the short side edge 9', while the auxiliary incisions 17 end at a distance from the short side edge 9.

In Figur 2 ist der Tragegriff 11 in einem angehobenen Zustand dargestellt, sodass der mit seinem Füllmaterial gefüllte Sack, der im gefüllten Zustand eine übliche Kastenform ausbildet, an dem Tragegriff 11 ergriffen und transportiert werden kann.In FIG. 2 the carrying handle 11 is shown in a raised state, so that the filled with his filling bag, which forms a standard box shape in the filled state, can be grasped and transported to the carrying handle 11.

Soll der volle Sack nunmehr entleert werden, kann ein Öffnungsvorgang stattfinden, der in den Figuren 3 und 4 sehr schematisch dargestellt ist.If the full bag is now emptied, an opening process can take place in the Figures 3 and 4 is shown very schematically.

Gemäß Figur 3 wird der Öffnungsvorgang des Sackes eingeleitet durch das Aufreißen der Öffnungslinie 8 durch Öffnen der Unterbrechungen 12, also beispielsweise Durchtrennen eines eingearbeiteten Gewebes. Die Hilfseinschnitte 17 erleichtern hierbei das Ergreifen des Bodendeckblatts 7 beiderseits der Öffnungslinie 8 im Bereich der kurzen Seitenkante 9, in dem beispielsweise die Fingernägel der Zeigefinger in die Hilfseinschnitte eingeführt werden können, sodass das Bodendeckblatt 7 beiderseits zur Öffnungslinie 8 im Bereich der kurzen Seitenkante 9 angehoben und ggf. das Trennen der Gewebefäden eingeleitet werden kann. In entsprechender Weise werden die Unterbrechungen 12 an der Trennlinie 8' geöffnet, sodass sich der Tragegriff 11 in die Teilgriffe 13 auftrennt.According to FIG. 3 the opening process of the bag is initiated by the rupture of the opening line 8 by opening the interruptions 12, so for example cutting through an incorporated fabric. The auxiliary cuts 17 in this case facilitate the gripping of the bottom cover sheet 7 on both sides of the opening line 8 in the area of the short side edge 9 in which, for example, the fingernails of the index fingers can be inserted into the auxiliary cuts, so that the bottom cover sheet 7 is raised on both sides to the opening line 8 in the region of the short side edge 9 and possibly the separation of the fabric threads can be initiated. In a corresponding manner, the interruptions 12 are opened at the parting line 8 ', so that the carrying handle 11 separates into the part handles 13.

Durch Aufziehen der Bodenklappen und Ausstülpen eines dadurch freigelegten Eckeinschlags 14 kann eine Ausschütttülle oder -rinne 15 gebildet werden, durch die eine Ausschüttöffnung 16 für das kontrollierte Entleeren des Füllmaterials aus dem Sack entsteht.By raising the bottom flaps and everting a corner impact 14 thus exposed, a discharge spout or gutter 15 can be formed through which a dispensing opening 16 for the controlled emptying of the filling material from the bag is formed.

Ist der Sack entleert, wird das Bodendeckblatt 7 vorzugsweise entlang der gesamten Öffnungslinie 8, einschließlich des Einschnittstücks 18 an der kurzen Seitenkante 9' geöffnet, sodass eine vollständige Sacköffnung im Bereich dieses Bodens möglich ist. Der Sack kann beispielsweise als Abfallsack verwendet werden, indem Abfallmaterialien durch die nunmehr vollständige Öffnung des Sacks im Bereich des Sackbodens in das Sackinnere eingebracht werden. Der so mit Abfall gefüllte Sack kann dann an den Teilgriffen 13 gehalten werden, die durch die ergreifende Hand zusammengehalten werden, sodass eine gut transportierbare Sackeinheit trotz der im Boden 4 ausgebildeten Ausschüttöffnung 16 entsteht.If the bag is emptied, the bottom cover sheet 7 is preferably opened along the entire opening line 8, including the incision piece 18 on the short side edge 9 ', so that a complete bag opening in the region of this soil is possible. The bag can be used, for example, as a rubbish bag by waste materials are introduced through the now complete opening of the bag in the area of the bag bottom in the bag interior. The thus filled with waste sack can then be held on the part handles 13, which are held together by the gripping hand, so that a well transportable bag unit despite the formed in the bottom 4 Ausschüttöffnung 16 is formed.

Der erfindungsgemäße Sack ist daher auch nach seiner Entleerung noch sinnvoll verwendbar und durch die Teilgriffe 13 bequem handhabbar.The bag according to the invention is therefore useful even after its emptying and convenient to handle by the part handles 13.
