Abstract

In the known stackable containers, the disadvantage is that residual liquids still remain in the region of the top part of the container adjacent to the filling nozzle when the liquid is poured out. In order to avoid this, the inside surfaces (18) of the transitional parts (12 to 19) of the container wall between the side parts at (3, 4) and the top part (5) of the container adjacent to the filling nozzle (7) are concavely curved, seen from the inside, and the radii (R1, R2) of curvature of these inner curves (18) are dimensioned such that the inside surfaces (18) merge continuously into the pouring-out region (19) of the filling nozzle (7). <IMAGE>

Description

Die vorliegende Erfindung betrifft einen aus Kunststoff bestehen­den vorzugsweise stapelbaren Behälter, an dessen die Behälter­decke bildenden Oberteil sowohl ein Griff als auch ein durch eine Verschlußkappe od dgl. absperrbarer Einfüllstutzen angeformt sind, wobei der diesem Griff oder dem Einfüllstutzen benachbarte Bereich des Oberteiles nach oben vorsteht und eine plane, das Aufsetzen eines weiteren gleichartigen Behälters ermöglichende Stapelfläche aufweist.The present invention relates to a preferably stackable container made of plastic, on the upper part of which forms the container cover, both a handle and a filler neck which can be shut off by a closure cap or the like are formed, the region of the upper part adjacent to this handle or the filler neck protruding upwards and has a flat stacking surface which enables the placement of a further similar container.

Derartige stapelbare und im allgemeinen eine kubische Gestalt aufweisende Behälter sind beispielsweise bekannt durch das Deut­sche Gebrauchsmuster 77 35 282 sowie auch der deutschen Offenle­gungsschrift 31 39 083. Obwohl die Steifigkeit dieser Behälter durch deren besondere Formgebung sehr groß ist und sich diese Be­hälter somit leicht und sicher stapeln lassen, so besteht doch immer noch der Nachteil, daß beim Ausgießen der in diesen Behäl­tern befindlichen Flüssigkeiten immer noch in dem dem Einfüll­stutzen benachbarten Bereich des Behälteroberteiles Restflüssig­keiten verbleiben, die auch bei einem vollständigen Kippen dieser Behälter nicht über den Einfüllstutzen abfließen können. Bisher hat man auf das Ausgießen auch dieser noch in den Behältern ver­bliebenen Restflüssigkeiten verzichtet, so daß diese Flüssigkei­ten zusammen mit den Behältern der Vernichtung zugeführt wurden. Bei dem heute gewachsenen Bewußtsein gegenüber durch solche Rest­flüssigkeiten bedingten Umweltschäden besteht nunmehr die Forde­rung, derartige Kunststoffbehälter vollständig zu leeren, so daß nur noch die Behälter selbst vernichtet werden müssen, in den Be­hältern jedoch keine eventuell für die Umwelt schädliche Rest­flüssigkeiten mehr enthalten sind.Such stackable and generally cubic-shaped containers are known, for example, from German Utility Model 77 35 282 and also from German Offenlegungsschrift 31 39 083. Although the stiffness of these containers is very great due to their special shape and these containers are therefore stacked easily and safely leave, so there is still the disadvantage that when pouring out the liquids in these containers, residual liquids still remain in the area of the upper part of the container adjacent to the filler neck, which cannot flow off the filler neck even when these containers are completely tilted. So far, there has been no pouring out of these residual liquids still remaining in the containers, so that these liquids have been disposed of together with the containers. With today's growing awareness of environmental damage caused by such residual liquids, there is now a requirement to completely empty such plastic containers so that only the containers themselves have to be destroyed, but the containers no longer contain any residual liquids which may be harmful to the environment.

Aufgabe der vorliegenden Erfindung ist es nunmehr, dieser zuvor behandelten Forderung einer vollständigen Entleerung solcher Be­hälter nachzukommen.The object of the present invention is now to meet this previously discussed requirement for complete emptying of such containers.

Diese Aufgabe wird erfindungsgemäß nun dadurch gelöst, daß die Innenflächen der zwischen den Seitenteilen und dem Oberteil des Behälters befindlichen, dem Einfüllstutzen benachbarten Über­gangsteile der Behälterwandung von innen gesehen konkav gewölbt und die Krümmungsradien dieser inneren Wölbungen so bemessen sind, daß diese Wölbungen kontinuierlich in den Ausgießbereich des Einfüllstutzens übergehen. Durch diesen Übergang der konkaven Wölbungen in den Ausgießbereich des Einfüllstutzens ist gewähr­leistet, daß keinerlei Restflüssigkeiten mehr im Oberteil des Be­hälters verbleiben und derselbe somit vollständig entleert werden kann.This object is now achieved in that the inner surfaces of the transition parts of the container wall located between the side parts and the upper part of the container, adjacent to the filler neck, are concavely curved from the inside and the radii of curvature of these inner curvatures are dimensioned such that these curvatures are continuously in the pouring area of the filler neck. This transition of the concave curvatures into the pouring area of the filler neck ensures that no residual liquids remain in the upper part of the container and the same can thus be completely emptied.

Bei dieser erfinderischen Gestaltung sind zweckmäßig die Innen­flächen sowohl der stirnseitigen als auch der seitlichen Über­gangsteile des Behälters konkav gewölbt. Die Krümmungsradien die­ser konkav gewölbten Innenflächen des Übergangsteiles weisen da­bei eine Länge von beispielsweise 1/10 bis 1/2 der Behältertiefe oder der Behälterbreite auf.In this inventive design, the inner surfaces of both the front and the side transition parts of the container are appropriately concave. The radii of curvature of these concavely curved inner surfaces of the transition part have a length of, for example, 1/10 to 1/2 of the container depth or the container width.

Darüber hinaus ist es ferner noch zweckmäßig, wenn auch die In­nenfläche des stirnseitigen Seitenteiles mindestens in dem dem Einfüllstutzen benachbarten Bereich konkav gewölbt und die zuge­hörigen Krümmungsradien dieser Innenwölbung relativ groß sind. Die Länge der Krümmungsradien dieser konkav gewölbten Innenfläche der Stirnseite des Behälters können dabei beispielsweise etwa 2 bis 5 mal größer sein als die Behälterbreite.In addition, it is also expedient if the inner surface of the front side part is concave at least in the area adjacent to the filler neck and the associated radii of curvature of this inner curvature are relatively large. The length of the radii of curvature of this concavely curved inner surface of the end face of the container can be, for example, about 2 to 5 times larger than the container width.

Weitere Einzelheiten der vorliegenden Erfindung ergeben sich aus der folgenden Beschreibung von zwei auf der Zeichnung dargestell­ten beispielsweisen Ausführungsformen sowie den zuvor bereits be­handelten Ansprüchen.Further details of the present invention will become apparent from the following description of two exemplary embodiments shown in the drawing and from the claims already discussed above.

Es zeigen:

  • Fig. 1 die schaubildliche Ansicht einer ersten Ausführungsform des erfindungsgemäßen Behälters,
  • Fign.2 bis 6 Einzelschnitte des Behälters gemäß der angegebenen Schnittlinien,
  • Fig.7 die schaubildliche Ansicht einer zweiten Ausführungs­form und
  • Fign.8 bis 12 Einzelschnitte dieser zweiten Ausführungsform gemäß den angegebenen Schnittlinien.
Show it:
  • 1 is a perspective view of a first embodiment of the container according to the invention,
  • FIGS. 2 to 6 individual sections of the container according to the cut lines indicated,
  • 7 shows the perspective view of a second embodiment and
  • 8 to 12 individual sections of this second embodiment according to the indicated cutting lines.

Der in den Fign. 1 bis 6 dargestellte Behälter 1 ist aus Kunst­stoff geblasen und weist einen Boden 2 sowie vier mit 3 und 4 be­zeichnete Seitenteile auf. Diese Seitenteile 3 und 4 laufen dabei in einen, die Behälterdecke bildenden Oberteil 5 aus, an dem ein Handgriff 6 angeformt und in dem ein durch eine nicht besonders dargestellte Schraubkappe verschließbarer Einfüllstutzen 7 einge­formt ist. Die Behälterbreite ist dabei mit b und die Behälter­tiefe mit t bezeichnet.The in the Figs. 1 to 6 shown container 1 is blown from plastic and has a bottom 2 and four with 3 and 4 designated side parts. These side parts 3 and 4 run into an upper part 5, which forms the container ceiling, on which a handle 6 is formed and in which a filler neck 7 which can be closed by a screw cap (not shown in particular) is formed. The container width is designated with b and the container depth with t.

Um mehrere Behälter 1 dieser Art sicher aufeinander stapeln zu können, weist dieser Oberteil 5 eine plane Stapelfläche 8 auf, die U-förmig gestaltet ist und sowohl den Handgriff 6 als auch den Einfüllstutzen 7 umgibt. Ferner sind an dieser Stapelfläche 8 mit 9 bezeichnete Warzen angeformt, die, wenn auf diesen Behälter 1 ein zweiter gleichartiger Behälter 1 aufgesetzt wird, von unten her in in dem Boden 2 des aufgesetzten Behälters 1 eingeformte, nicht besonders dargestellte Mulden od. dgl. hineingreifen. Fer­ner ist im Boden 2 jedes Behälters 1 noch eine mit 10 bezeichnete Rinne od. dgl. eingeformt zur Aufnahme des über die Stapelfläche 8 nach oben vorstehenden Oberteiles 11 des an dem Behälterober­teil 5 angeformten Handgriffes 6.In order to be able to safely stack several containers 1 of this type on top of one another, this upper part 5 has a flat stacking surface 8 which is U-shaped and surrounds both the handle 6 and the filler neck 7. Furthermore, warts, designated 9, are formed on this stacking surface 8, which, when a second container 1 of the same type is placed on this container 1, reach from below into troughs or the like, not particularly shown, formed in the bottom 2 of the container 1 placed thereon . Furthermore, in the bottom 2 of each container 1 there is also a groove or the like, designated 10, for receiving the upper part 11 of the handle 6 formed on the upper part 5 of the container, which protrudes upwards above the stacking surface 8.

Wie sich weiter inbesondere aus der Fig. 1 ergibt, so weist der Oberteil 5 des erfindungsgemäßen Behälters 1 vier mit 12 bis 15 bezeichnete Übergangsteile auf, die nach außen konvex gewölbt sind und einerseits bündig mit den Oberkanten 16 der Seitenteile 3 und 4 abschließen und andererseits bündig in die plane Stapel­fläche 8 übergehen.As can further be seen in particular from FIG. 1, the upper part 5 of the container 1 according to the invention has four transition parts, designated 12 to 15, which are convexly curved outwards and, on the one hand, are flush with the upper edges 16 of the side parts 3 and 4, and on the other hand merge flush into the flat stacking surface 8.

Damit nun beim Ausgießen der in dem Behälter 1 befindlichen Flüs­sigkeit nicht etwa noch Reste derselben in den dem Einfüllstutzen benachbarten Übergangsteilen 12 bis 15 verbleiben, sind die In­nenflächen 17 und 18 dieser Übergangsteile 12 bis 15 von innen gesehen konkav gewölbt, wobei dann die Krümmungsradien Rl und R2 so bemessen sind, daß die Wölbungen dieser Übergangsteile 12 bis 15 kontinuierlich in den Bereich 19 des an dem Oberteil 5 ange­formten Einfüllstutzens 7 übergehen. Diese zuvor erwähnten Krüm­mungsradien Rl und R2 weisen dabei eine Länge auf, die etwa gleich 1/10 bis 1/2 der Behälterbreite b oder der Behältertiefe t sind.So that when the liquid in the container 1 is poured out, no residues of it remain in the transition parts 12 to 15 adjacent to the filler neck, the inner surfaces 17 and 18 of these transition parts 12 to 15 are concave from the inside, with the radii of curvature R1 and R2 are dimensioned so that the curvatures of these transition parts 12 to 15 continuously transition into the area 19 of the filler neck 7 formed on the upper part 5. These previously mentioned radii of curvature R1 and R2 have a length which is approximately equal to 1/10 to 1/2 of the container width b or the container depth t.

Bei der in der Fig. 7 schaubildlich dargestellten zweiten Ausfüh­rungsform des erfindungsgemäßen Behälters 21 sind dessen Bauteile durch die gleichen Bezugszeichen gekennzeichnet, wie diese zuvor auch schon bei der ersten Ausführungsform verwendet worden sind. Gegenüber dieser ersten Ausführungsform unterscheidet sich der Behälter 21 noch dadurch, daß dessen stirnseitige Wand 22 bereits konvex gewölbt ist, wobei die konkave Wölbung 23 der Innenfläche 24 dieser Seitenwand 22 kontinuierlich in den Ausgießbereich 19 des Einfüllstutzen 7 übergeht. Durch diese konvexe Gestaltung der stirnseitigen Behälterwand 22 ist einerseits eine ausreichende Steifigkeit des Behälters 21 gewährleistet, andererseits aber vermag die in dem Behälter 21 befindliche Flüssigkeit kontinuier­lich in den Einfüllstutzen 7 abzufließen. Der in diesem Fall vor­gesehene Krümmungsradius R3 dieser Behälterwand 22 weist dabei eine Länge auf, dies 2 bis 5 mal größer ist als die Behälterbrei­te b.In the second embodiment of the container 21 according to the invention, shown diagrammatically in FIG. 7, its components are identified by the same reference numerals as have already been used in the first embodiment. Compared to this first embodiment, the container 21 also differs in that its end wall 22 is already convex, the concave curvature 23 of the inner surface 24 of this side wall 22 continuously merging into the pouring area 19 of the filler neck 7. This convex design of the end-side container wall 22 ensures sufficient stiffness of the container 21 on the one hand, but on the other hand the liquid in the container 21 can flow continuously into the filler neck 7. The radius of curvature R3 of this container wall 22 provided in this case has a length that is 2 to 5 times larger than the container width b.
