Description

Die vorliegene Erfindung betrifft als Zusatz zur deutschen Patentanmeldung P 40 01 429 die Weiterentwicklung der dort beschriebenen faltbaren Vorratsflasche für schütt- oder fließfähige Güter. Die Flasche ist besonders leichtgewichtig herstellbar, verursacht somit nur einen geringen Kunststoffverbrauch und ist dennoch von einer durch die Formgebung bedingten hohen Stabilität. Der Flaschenkörper besitzt dabei einen sechseckig gestreckten, flachen Querschnitt mit Innenkanten und spitz zu faltbaren Außenkanten zulaufenden Außenwinkeln, wobei der Boden unter Bildung von äußeren, ausgerundeten Bodenkanten nach innen eingezogen ist und eine sich längs zwischen den Enden der Außenkante erstreckende faltbare Mittellinie besitzt, wobei die Bodenkanten vier äußere ansteigende Abschrägungen aufweisen, die zu den Enden der Außenkanten zusammenlaufen.As an addition to German patent application P 40 01 429, the present invention relates to the further development of the foldable storage bottle for pourable or flowable goods described there. The bottle can be manufactured particularly light-weight, thus causes only little plastic consumption and is nevertheless of a high stability due to the shape. The bottle body has a hexagonally elongated, flat cross-section with inner edges and outer angles tapering to foldable outer edges, the bottom being drawn inward to form outer, rounded bottom edges and having a foldable center line extending longitudinally between the ends of the outer edge, the Bottom edges have four outer rising bevels that converge to the ends of the outer edges.

Die Flaschenform zeichnet sich dadurch aus, daß sie selbst bei Verwendung geringer Wandstärken formstabil und standfest ist. Gleichzeitig läßt sie sich leicht zu einem flachen Gebilde zusammendrücken, wodurch lediglich ein Bruchteil des bisher in Kauf zu nehmenden Abfallvolumens anfällt.The bottle shape is characterized in that it is dimensionally stable and stable even when using thin walls. At the same time, it can be easily compressed into a flat structure, which means that only a fraction of the volume of waste that had previously been accepted.

Die erhöhten Bodenkanten sind dabei zu vier konvexen Ausbuchtungen ausgerundet, die an der Mitte der beiden inneren Flaschenflächen von einer Einziehung ausgehen und paarweise zu den Enden der Außenkanten zusammenlaufen. Es entstehen auf diese Weise vier, etwa punktförmige Auflagen auf der Stellfläche.The raised bottom edges are rounded out to four convex bulges, which assume a contraction at the center of the two inner bottle surfaces and converge in pairs to the ends of the outer edges. Arise in this way four, approximately punctiform supports on the footprint.

Die Flasche kann eine übliche Form aufweisen, wobei die Innenkanten des gestreckt - sechseckigen Querschnitts zu der Ausgießöffnung zusammenlaufen. Dabei ist es nicht erforderlich, daß die Ausgießöffnung im Bereich der Mittelachse der Flasche liegt, sie kann insbesondere auch seitlich versetzt sein.The bottle can have a customary shape, the inner edges of the stretched-hexagonal cross-section converging to the pouring opening. It is not necessary for the pouring opening to lie in the region of the central axis of the bottle; in particular, it can also be offset laterally.

Der Flaschenkörper kann Griffmulden aufweisen, die zur Erleichterung des Zusammendrückens ebenfalls linienförmige Faltkanten mit vorzugsweise geringen Knickradien zeigt, um die Formstabilität durch bei größeren Radien entstehende Sicken-Wirkung möglichst gering zu halten.The bottle body can have recessed grips which, in order to facilitate the compression, also have linear folding edges with preferably small kink radii in order to keep the shape stability as low as possible by the beading effect occurring with larger radii.

Insbesondere ist die Flasche mit einem Hohlgriff versehen, wobei zwischen diesem und dem Flaschenkörper ein Durchbruch freibleibt. Hohlgriff und Flaschenkörper besitzen dabei innere und äußere eigene Faltkanten.In particular, the bottle is provided with a hollow handle, an opening being left free between this and the bottle body. Hollow handle and bottle body have their own inner and outer folding edges.

Die Flaschenform wird im Blasverfahren hergestellt, wobei sich Ausgangswandstärken für die Folien von etwa 0,3 bis 0,5 mm (bei einem Flaschenvolumen von 1 l) besonders bewährt haben.The bottle shape is produced using the blowing process, with initial wall thicknesses of approximately 0.3 to 0.5 mm (for a bottle volume of 1 l) having proven particularly useful.

Der Körper selbst ist relativ flach, wobei die Kantenabstände der inneren Flaschenflächen im Bereich - unterhalb der gegebenenfalls vorzunehmenden Zusammenführung zum Ausgießstutzen hin - etwa das dreifache des Abstandes der Außenkanten von den Innenkanten betragen.The body itself is relatively flat, with the edge distances of the inner bottle surfaces in the region - below the possible merge towards the pouring spout - being approximately three times the distance between the outer edges and the inner edges.

Der Faltvorgang selbst geschieht durch Zusammendrücken oder Flachlegen.The folding process itself is done by squeezing or laying flat.

Diese Lösung weist die folgenden Nachteile auf. Zum einen können sich im Bereich der Standpunkte der Bodenkanten sogenannte Elefantenfüße bilden, wenn der Flaschenboden z.B. in Gebinden beim Transport mit wesentlich höherem als dem Eigengewicht belastet wird. Darüber hinaus ist nur ein Faltvorgang durch die Formvorgabe sicher möglich, ein Umklappen des Bodens auf die Seitenfläche der Flasche erfordert ein sorgfältiges Vorgehen, da für die zusammenfaltende Person keine Möglichkeit hierfür erkennbar ist. Andererseits wird dieses Zusammenfalten bisweilen bevorzugt.This solution has the following disadvantages. On the one hand, so-called elephant feet can form in the area of the points of view of the bottom edges if the bottle bottom e.g. in containers with loads that are significantly higher than their own weight. In addition, only a folding process is safely possible due to the shape specification, folding the bottom onto the side surface of the bottle requires a careful procedure, since there is no way of recognizing this for the person folding up. On the other hand, this folding is sometimes preferred.

Die vorliegende Erfindung hat sich gegenüber der Basisanmeldung daher die Aufgabe gestellt, die dort beschriebene Lösung so abzuwandeln, daß einmal eine höhere Bodenstabilität erreicht und zusätzlich auch ein Zusammenfalten unter Umklappen des Bodens möglich bzw. erleichtert wird.Compared to the basic application, the present invention therefore has the task of modifying the solution described there in such a way that once a higher floor stability is achieved and in addition a folding is possible or facilitated by folding the floor.

Die Lösung dieser Aufgabe gelingt bei einer Vorratsflasche für schütt- oder fließfähige, insbesondere für Haushaltsgüter, bestehend aus einem Kunststoffkörper mit einer verschließbaren Ausgießöffnung, bei welcher der Körper einen sechseckigen gestreckten, flachen Querschnitt mit Innenkanten und im wesentlichen spitz zu faltbaren Außenkanten zulaufenden Außenwinkeln aufweist, und der Boden unter Bildung von äußeren Bodenkanten nach innen eingezogen ist und eine längs verlaufende Mittelkante sowie eine dazu mittig quer verlaufende, eingezogene Querlinie aufweist, erfindungsgemäß dadurch, daß die Außenkanten je zu dreiecksförmigen, schräg ansteigenden Abflachungen auslaufen und Schenkel besitzen, die in nach außen gerichtete Ausrundungen übergehen, und daß an die Schenkel sich jeweils parallel zur Mittellinie liegende, geringfügig nach innen verlagerte, waagerechte Abschnitte als Bodenkanten anschließen, die mittig zur Querlinie hochgezogen sind, und die Breitflächen etwa in Höhe des Schnittpunktes der Schenkel zwischen den Innenkanten mindestens eine Faltlinie aufweisen.This object is achieved with a storage bottle for pourable or flowable, in particular for household goods, consisting of a plastic body with a closable pouring opening, in which the body has a hexagonal, elongated, flat cross section with inner edges and outer angles tapering sharply to foldable outer edges, and the floor is drawn inwards to form outer floor edges and has a longitudinal central edge and a transverse line running in the middle, in accordance with the invention in that the outer edges each run out into triangular, obliquely rising flats and have legs that extend inwards directional fillets, and that on the thighs lying parallel to the center line, slightly inward connect shifted, horizontal sections as bottom edges, which are drawn up in the middle of the transverse line, and the broad surfaces have at least one fold line at about the intersection of the legs between the inner edges.

Die dreiecksförmige Abflachung schließt dabei stumpf, etwa unter einem Winkel von 150° bis 170° an die Bodenkanten an.The triangular flattening connects bluntly, approximately at an angle of 150 ° to 170 °, to the bottom edges.

Durch die Auflage der Flasche auf je vier abgeflachten Bodenkanten wird überraschenderweise in Zusammenhang mit der seitlichen, zu den Außenkanten zusammenlaufenden dreiecksförmigen Abflachungen eine deutlich erhöhte Stabilität erreicht.By placing the bottle on four flattened bottom edges, a significantly increased stability is surprisingly achieved in connection with the lateral triangular flats converging to the outer edges.

Eine weitere Verbesserung der Stabilität und eine definierte Bodenlinienführung mit ansprechender Gestaltung wird erreicht, wenn an die äußeren Bodenkanten, von deren inneren Enden Sicken ausgehen, die zum Bodenmittelpunkt zusammenlaufen.A further improvement in stability and a defined floor line guidance with an appealing design is achieved if the outer floor edges, from the inner ends of which have beads that converge to the center of the floor.

Besonders gut gewährt hat sich dabei ein Maßverhältnis, bei welchem die Schenkel der dreiecksförmigen Abflachungen etwa die 3- bis 4-fache Länge der Mittelkante aufweisen.A dimension ratio in which the legs of the triangular flats have approximately 3 to 4 times the length of the central edge has been granted particularly well.

Die neue Art des Zusammenfaltens zusätzlich zur Bisherigen wird dadurch ermöglicht, daß zwischen den Innenkanten mindestens auf einer Flaschenbreitfläche eine Faltlinie angeordnet ist, die zum Falten beim Zusammendrücken eine definierte Knicklinie bildet, wobei sie sich hierbei in das Material des Randbereichs fortsetzt.The new way of folding in addition to the previous one is made possible by the fact that a fold line is arranged between the inner edges at least on a wide bottle surface, which forms a defined crease line for folding when pressed together, whereby it continues in the material of the edge region.

Letztlich wird noch vorgeschlagen, auch die Außenkanten zu versteifen, wobei neben den Außenkanten parallel zu diesen eng beabstandet verlaufende Außensickenpaare angeordnet sind. Diese behindern den Faltvorgang durch die genaue Festlegung der Faltlinie nicht, erleichtern aber das Flachdrücken des Flaschenkörpers bei gleichzeitiger Erhöhung der Formstabilität.Ultimately, it is also proposed to stiffen the outer edges, with pairs of outer beads running parallel to the outer edges being arranged next to the outer edges. These do not hinder the folding process due to the precise definition of the folding line, but make it easier to flatten the bottle body while increasing the dimensional stability.

Anhand der beiliegenden Figuren wird die vorliegende Erfindung näher erläutert.

Wie in Figur 1 dargestellt, entspricht die erfindungsgemäße Flasche 1 in ihrem sechseckigen Querschnitt weitgehend dem Aufbau der Hauptanmeldung mit den Außenkanten 2 sowie den Innenkanten 10.The present invention is explained in more detail with reference to the accompanying figures.

Figure 2

Figure 3
shows the bottom of the bottle
As shown in FIG. 1 , the bottle 1 according to the invention largely corresponds in its hexagonal cross section to the structure of the main application with the outer edges 2 and the inner edges 10.

Am Boden sind zu den Seiten hin dreiecksförmige Abflachungen (7; Figur 2) vorgesehen, deren Schenkel 8 spitz zu den Außenkanten 2 zulaufen, an die nach außen Ausrundungen (9, Fig. 2) anschließen und die unten in vier Bodenkanten 4 übergehen, welch letztere mittig in eine nach oben gerichtete Einziehung 5 zusammengeführt sind. Die Bodenkanten 4 bilden die vier Stellflächen der Flasche 1. Oberhalb der Einziehung 5 verläuft mindestens auf einer Breitfläche 12 eine Faltlinie 16, die durch Profilierung in der Blasform eingeprägt wird. Die Faltlinie ist dabei so ausgerichtet, daß sie parallel zu den Bodenkanten 4 in Höhe der Schnittpunkte der Schenkel 8 der dreiecksförmigen Abflachung verläuft und an den Innenkanten 10 endet. Zum Zusammenfalten wird die Flasche 1 auf eine Unterlage gelegt. Mit den Händen wird sodann die Flasche im Bereich der Faltlinie eingedrückt, wobei sich der Boden umklappt. Der Boden wird auf die Flasche gedrückt und diese dabei flachgedrückt und Luft aus deren Innerem entfernt.Triangular-shaped flats (7; FIG. 2) are provided on the floor to the sides, the legs 8 of which taper to the outer edges 2, to which the rounded edges (9, FIG. 2) connect and which merge into four floor edges 4 below, which the latter are brought together in the middle in an upward confiscation 5. The bottom edges 4 form the four storage areas of the bottle 1. Above the indentation 5, a fold line 16 runs at least on a wide area 12, which is embossed by profiling in the blow mold. The fold line is oriented so that it runs parallel to the bottom edges 4 at the level of the intersection of the legs 8 of the triangular flattening and ends at the inner edges 10. To fold the bottle 1 is placed on a pad. With the hands the bottle is then pushed in in the area of the fold line, the base folding over. The bottom is pressed onto the bottle, flattening it and removing air from the inside.

Verschließt man danach die entleerte Flasche, behält sie bekanntermaßen ihren zusammengelegten flachen Zustand bei, wodurch das Abfallvolumen beträchtlich vermindert werden kann.If one then closes the emptied bottle, it is known to maintain its collapsed flat state, as a result of which the volume of waste can be considerably reduced.

Das Zusammenlegen des Flaschenkörpers kann durch parallel zu den Außenkanten in geringem Abstand von diesen (etwa 5 mm) angeordneten, nach innen eingezogenen Sicken 15 erleichtert werden, wobei sich diese bis zum oberen Gewinderand 17 erstrecken können.The folding of the bottle body can be facilitated by parallel to the outer edges at a small distance from these (about 5 mm), inwardly drawn beads 15, which can extend to the upper thread edge 17.

Figur 2 zeigt in Schmalansicht die Ausrundungen 9 sowie das Profil der Bodenkanten 4, die ebenfalls leicht ausgerundet sein können. In Draufsicht ist die hochliegende, längsverlaufende Mittelkante 6 zwischen den Bodenkanten erkennbar ebenso wie die dreiecksförmige Abflachung 7 zwischen den Schenkeln 8 und den bodenseitigen Übergangslinien 18 von der Bodenfläche an die Abflachung 7. Figure 2 shows a narrow view of the fillets 9 and the profile of the bottom edges 4, which can also be slightly rounded. In plan view, the high, longitudinal central edge 6 between the bottom edges can be seen, as can the triangular flattening 7 between the legs 8 and the bottom-side transition lines 18 from the bottom surface to the flattening 7.

Seitlich sind die Faltlinien 16 erkennbar, die an den Innenkanten 10 enden, und von denen grundsätzlich nur eine erforderlich ist.Laterally, the fold lines 16 can be seen, which end at the inner edges 10 and of which only one is required in principle.

Figur 3 zeigt den Boden 3 in Draufsicht. Die Flasche läuft zwischen den Schenkeln 8 zu spitzen Winkeln α zusammen und ist hier zu den dreiecksförmigen Abflachungen 7 hochgezogen. Die Übergangslinien 18 schließen die Abflachung 7 noch unten ab. An diese schließen sich die vier, leicht nach innen verlegten Bodenkanten 4 an, auf denen die Flasche ruht, die Abflachung 7 schließt dabei unter einem Winkel β (150° - 170°) an die Bodenkanten 4 an (Fig. 1). Figure 3 shows the bottom 3 in plan view. The bottle converges at acute angles α between the legs 8 and is drawn up to the triangular flats 7 here. The transition lines 18 complete the flattening 7 below. These are followed by the four, slightly inwardly laid bottom edges 4, on which the bottle rests, the flat 7 adjoins the bottom edges 4 at an angle β (150 ° - 170 °) (FIG. 1).

Die Bodenkanten verlaufen nicht bis zu eingeformten Querlinie 11, sondern enden auf etwa halbem Wege und sind unter, zum Bodenmittelpunkt 14 über Bodensicken 13 zu diesem fortgesetzt, wodurch sich zur Querlinie 11 ansteigende dreiecksförmige Bereich 19 bilden.The bottom edges do not run up to the formed transverse line 11, but end approximately halfway and are continued below, to the center of the floor 14 via floor beads 13, thereby forming triangular regions 19 rising to the transverse line 11.

Die Mittelkante 6 ist erhaben und durch die Formteilung beim Blasen gebildet. Die Flasche kann auch über diese Linie gefaltet werden,wenn man diese beim Liegen lediglich flachgedrückt, ohne den Boden vorher zu falten.The central edge 6 is raised and formed by the shape division during blowing. The bottle can also be folded over this line if you just flatten it while lying down without folding the bottom beforehand.
