Abstract

The container has an atmospheric pump connected with a riser pipe (3) and engaged in the container to suck and deliver a container capacity. A hollow region (5) is formed in a container base, where the riser pipe has a sufficient length such that free ends of the pipe engage in the hollow region. A small gap is present between the free ends of the riser pipe and a base of the hollow region. The hollow region has a cross shape that is formed from two cross laminar channels, where the hollow region is confined by an inclined wall section (6), and the container is made of plastic.

Description

Die Erfindung betrifft einen Behälter mit einer Pumpe, die mit einem Steigrohr verbunden ist, das in den Behälter eingreift, um Behälterinhalt anzusaugen und aus dem Behälter abzugeben, wobei in der Wand des Behälterbodens ein vertiefter mittiger Bereich ausgebildet ist und das Steigrohr eine solche Länge hat, dass sein freies Ende in den vertieften Bereich eingreift.The invention relates to a container with a pump, which is connected to a riser, which engages in the container to draw container contents and deliver it from the container, wherein in the wall of the container bottom a recessed central region is formed and the riser has such a length in that its free end engages in the recessed area.

Bei dem Behälter handelt es sich vorzugsweise um eine Flasche mit einem Flaschenhals, ohne dass die Erfindung jedoch auf diese Behälterform beschränkt ist. Der Behälter ist vorzugsweise zur Aufnahme einer Flüssigkeit bestimmt, wobei der Behälterinhalt aber auch eine cremige Substanz sein kann. In einer besonders bevorzugten Ausführungsform ist der Behälter ein kleines Fläschchen zur Abgabe von Augen- und Nasentropfen.The container is preferably a bottle with a bottle neck, without, however, limiting the invention to this type of container. The container is preferably intended for receiving a liquid, but the container contents may also be a creamy substance. In a particularly preferred embodiment, the container is a small vial for dispensing eye and nose drops.

Bei herkömmlichen Behältern, bei denen der Inhalt durch Betätigung einer atmosphärischen Pumpe durch ein Steigrohr angesaugt wird, besteht das Problem, dass eine Restmenge in dem Behälter verbleibt, die mittels der Pumpe nicht ausgebracht werden kann.In conventional containers, in which the content is sucked through a riser by operation of an atmospheric pump, there is the problem that a residual amount remains in the container, which can not be discharged by means of the pump.

Es sind aber auch schon Behälter mit Pumpen der eingangs genannten Art bekannt, deren Behälterboden eine mittige Vertiefung hat, in die das Steigrohr eingreift.But there are already known container with pumps of the type mentioned, the container bottom has a central recess into which engages the riser.

DE 602 06 036 T2 offenbart einen gattungsgemäßen Behälter mit einem torischen Fußteil beträchtlicher Dicke, wobei die Innenfläche des Bodens eine konische Fläche hat, die in eine mittige Mulde einmündet. Eine solche Flasche ist auch in der WO 01/62626 A1 offenbart. DE 602 06 036 T2 discloses a generic container with a toric foot of considerable thickness, the inner surface of the floor having a conical surface, which opens into a central depression. Such a bottle is also in the WO 01/62626 A1 disclosed.

US 2006/0144868 A1 offenbart einen Behälter mit zwei parallelen rinnenförmigen Bodenabschnitten, auf denen der Behälter aufruht. Außerdem ist eine mittige Einbuchtung in der Bodenwand vorgesehen. US 2006/0144868 A1 discloses a container having two parallel trough-shaped bottom portions on which the container rests. In addition, a central recess in the bottom wall is provided.

US 2005/0092777 A1 offenbart einen Behälter, der eine konische Bodenwand mit einer mittigen Einbuchtung enthält. Damit der Behälter stehen kann, ist er mit einer Bodenkappe versehen. Dies ist auch bei dem Gegenstand der CA 2 506 145 A1 der Fall. US 2005/0092777 A1 discloses a container containing a conical bottom wall with a central indentation. So that the container can stand, it is provided with a bottom cap. This is also the case of the CA 2 506 145 A1 the case.

EP 0 499 537 A1 und WO 98/08616 offenbaren Behälter mit einer im Verhältnis zur Behälterwand dicken Bodenwand mit einer konisch auf eine mittige Einbuchtung zulaufenden Innenwand. EP 0 499 537 A1 and WO 98/08616 disclose containers with a bottom wall which is thick in relation to the container wall and which has a conical wall tapering towards a central recess.

EP 1 621 255 A1 offenbart einen mit einem Bodenteil zusammengesetzten Behälter, dessen Innenwand großflächig konkav geformt ist. Die Innenwand des Bodenteils ist durch untere Rippen abgestützt, die Figur 4 der Druckschrift zeigt. EP 1 621 255 A1 discloses a container which is assembled with a bottom part and whose inner wall has a concave shape over a large area. The inner wall of the bottom part is supported by lower ribs, the FIG. 4 the publication shows.

US 2007/0181605 A1 offenbart einen Behälter mit einer ebenen Bodenfläche, die eine mittige Vertiefung hat. US 2008/0023499 A1 offenbart einen Behälter mit einer konvexen Bodenwand, bei der sich die Restflüssigkeit am Rand des Bodens sammelt. US 2007/0181605 A1 discloses a container with a flat bottom surface having a central recess. US 2008/0023499 A1 discloses a container with a convex bottom wall in which the residual liquid collects at the edge of the bottom.

US 3409181 A offenbart eine Quetschflasche, die zwei sich kreuzende Vertiefungen in ihrer Bodenwand enthält, die nur dann, wenn der Behälter zur Abgabe von Flüssigkeit seitlich zusammen gequetscht wird, geneigt zu dem mittigen vertieften Bereich verlaufen. US 3,409,181 A discloses a squeeze bottle which includes two intersecting recesses in its bottom wall which, when the liquid dispensing container is laterally squeezed together, are inclined to the central recessed area.

In dem in Figur 4 dargestellten Ausgangszustand des Behälters verlaufen die beiden streifenförmigen Vertiefungen schräg nach außen. Dies ist die Form des Behälters im spannungslosen Ausgangszustand. Figur 1 zeigt den Behälter mit einem eingesetztem Steigrohr. Die untere Stirnfläche des Steigrohrs ist dabei so gegen den Boden des Behälters gepresst, dass die Bodenwand eben ist. In diesem Zustand wird der Behälter mit Flüssigkeit befüllt, die nicht ungewollt aus dem Behälter austreten kann, da das Steigrohr in seinem an die Bodenwand angepressten Zustand dicht verschlossen ist. Erst wenn der Behälter seitlich zusammen gedrückt wird, wölbt sich der Behälterboden nach unten, wodurch das Steigrohr von der mittigen Vertiefung beabstandet wird und Behälterinhalt infolge der Komprimierung der in dem Behälter befindlichen Luft durch das Steigrohr abgeben wird.In the in FIG. 4 illustrated initial state of the container, the two strip-shaped recesses extend obliquely outward. This is the shape of the container in the de-energized initial state. FIG. 1 shows the container with an inserted riser. The lower end face of the riser is pressed against the bottom of the container so that the bottom wall is flat. In this state, the container is filled with liquid that can not escape unintentionally from the container, since the riser is sealed in its pressed against the bottom wall state. Only when the container is laterally compressed does the container bottom bulge, thereby spacing the riser from the central recess and discharging container contents through the riser as a result of the compression of the air in the container.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Anordnung aus Behälter mit Pumpe und Steigrohr so auszubilden, dass die Restflüssigkeit kleiner ist, als dies bei herkömmlichen Behältern der Fall ist.The present invention has for its object, an arrangement of container with pump and riser in such a way that the residual liquid is smaller than is the case with conventional containers.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved by the features of claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Advantageous embodiments of the invention are characterized in the subclaims.

Die Erfindung sieht vor, dass in den vertieften mittigen Bereich zwei streifenförmige Vertiefungen in der Wand des Behälterbodens einmünden, die geneigt zu dem mittigen vertieften Bereich hin verlaufen.The invention provides that in the recessed central region two strip-shaped depressions open in the wall of the container bottom, which extend inclined to the central recessed area.

Dabei ist bevorzugt, dass zwischen dem freien Ende des Steigrohrs und dem Boden des vertieften Bereichs ein kleiner Abstand verbleibt, der in der Größenordnung von einigen zehntel Millimeter bis 1 bis 2 mm beträgt, ohne dass die Erfindung auf diese Abmessungen beschränkt ist.It is preferred that between the free end of the riser and the bottom of the recessed area remains a small distance which is of the order of a few tenths of a millimeter to 1 to 2 mm, without the invention being limited to these dimensions.

Dabei liegt es aber auch im Rahmen der Erfindung, dass das Steigrohr mit seinem freien Ende auf dem Boden des vertieften Bereichs aufruht, wobei dann sicher zu stellen ist, dass die Flüssigkeit im ausreichenden Maße in das Steigrohr eintreten kann. Hierzu kann das untere Ende des Steigrohrs abgeschrägt sein.It is also within the scope of the invention that the riser rests with its free end on the bottom of the recessed area, in which case it must be ensured that the liquid can enter the riser pipe to a sufficient extent. For this purpose, the lower end of the riser beveled.

In dem vertieften Bereich sammelt sich die Restflüssigkeit, wenn nahezu der gesamte Behälterinhalt abgegeben worden ist, so dass das Steigrohr diese Restmenge fast vollständig aus dem vertieften Bereich ansaugen kann. Zahlreiche Versuche haben ergeben, dass durch diese Ausbildung die im Behälter verbleibende, nicht auszubringende Restflüssigkeit nur einen Bruchteil der in einem herkömmlichen Behälter zurück bleibenden Flüssigkeitsmenge beträgt.In the recessed area, the residual liquid collects when almost the entire container contents has been dispensed, so that the riser pipe can almost completely suck this remaining amount from the recessed area. Numerous experiments have shown that this training, the residual liquid remaining in the container is only a fraction of the liquid remaining in a conventional container amount of liquid.

Der vertiefte Bereich des Behälterbodens befindet sich in der Mitte des Behälterbodens, derart, dass das Steigrohr geradlinig von der Saugseite der Pumpe bis in den vertieften Bereich verläuft.The recessed portion of the container bottom is located in the center of the container bottom, such that the riser extends straight from the suction side of the pump to the recessed portion.

Enfindungsgemäß hat der vertiefte Bereich des Bodens eine Kreuzform. Dies bedeutet, dass sich zwei streifenförmige Vertiefungen im Behälterboden kreuzen, wobei die streifenförmigen Vertiefungen auch als Rinnen betrachtet werden können, in denen die Restflüssigkeit zum mittigen Kreuzungsbereich fließt, in den das freie Ende des Steigrohrs eingreift. Die streifenförmigen Rinnen laufen schräg zur muldenförmigen Mitte, dem tiefsten Punkt des Behälterbodens. Es liegt aber auch im Rahmen der Erfindung, dass der vertiefte Bereich in der Mitte des Bodens liegt und eine Kreisform oder die Form eines Vierecks oder Mehrecks hat. Dabei ist bevorzugt, dass der umgebende Boden des Behälters leicht schräg zu dem vertieften Bereich hin verläuft, damit sich die Restflüssigkeit in der Vertiefung ansammeln kann.According to the invention, the recessed area of the floor has a cross shape. This means that two strip-shaped depressions intersect in the container bottom, wherein the strip-shaped depressions can also be regarded as channels in which the residual liquid flows to the central crossing region, in which engages the free end of the riser. The strip-shaped grooves run diagonally to the trough-shaped center, the lowest point of the container bottom. It is also within the scope of the invention, that the recessed area lies in the middle of the floor and has a circular shape or the shape of a quadrangle or polygon. It is preferred that the surrounding bottom of the container extends slightly obliquely to the recessed area, so that the residual liquid can accumulate in the recess.

Weiter wird mit Vorteil vorgeschlagen, dass der vertiefte Bereich von im wesentlichen senkrechten Wandabschnitten begrenzt ist, ohne dass die Erfindung hierauf beschränkt ist. Diese Wandabschnitte stellen sicher, dass das freie Ende des Steigrohrs, das in seiner Länge auf die Abmessungen des Behälters abgestimmt ist, in dem vertieften Bereich gefangen ist.Furthermore, it is advantageously proposed that the recessed area is bounded by essentially vertical wall sections, without the invention being restricted thereto. These wall sections ensure that the free end of the riser, which is tuned in its length to the dimensions of the container, is trapped in the recessed area.

Der Behälter besteht vorteilhafterweise aus Kunststoff und kann z.B. im Extrusionsblasverfahren hergestellt sein, ohne dass die Erfindung auf dieses Material und das genannte Herstellungsverfahren beschränkt ist.The container is advantageously made of plastic and may e.g. be prepared by extrusion blow molding, without the invention being limited to this material and said production method.

Mit der Erfindung wird erreicht, dass die in dem Behälter zurückbleibende Restflüssigkeit beträchtlich reduziert wird. Da der vertiefte Bereich an einer solchen Stelle ausgebildet ist, dass das Steigrohr einen gradlinigen Verlauf hat und in dem vertieften Bereich gehalten ist, kann der Behälterinhalt völlig ungehindert durch das Steigrohr angesaugt und ausgebracht werden. Sollte das Steigrohr eine kleine Überlänge haben und mit seinem freien Ende auf dem Boden des vertieften Bereichs aufruhen und sich dabei - gefangen in dem vertieften Bereich - leicht seitlich ausbiegen, beeinträchtigt dies aber nicht die Funktionsfähigkeit und die Fähigkeit, den gesamten Behälterinhalt bis auf eine vernachlässigbar kleine Restmenge auszubringen.With the invention it is achieved that the residual liquid remaining in the container is considerably reduced. Since the recessed portion is formed at such a position that the riser has a straight course and is held in the recessed area, the container contents can be sucked and discharged completely unhindered by the riser. Should the riser have a small excess length and rest with its free end on the bottom of the recessed area and thereby slightly deflect laterally, caught in the recessed area, this does not affect the functionality and the ability to neglect the entire contents of the container except for one to spend small residual amount.

Figur 1 zeigt das komplette System, das im wesentlichen aus einem Behälter 1, einer insgesamt mit dem Bezugszeichen 2 bezeichneten atmosphärischen Pumpe, deren Einzelheiten hier nicht von Interesse sind, und einem Steigrohr 3 besteht, das auf bekannte Weise mit der Pumpe verbunden ist. FIG. 1 shows the complete system, which consists essentially of a container 1, an atmospheric pump designated generally by the reference numeral 2, the details of which are not of interest here, and a riser 3, which is connected in a known manner to the pump.

Das Steigrohr 3 verläuft geradlinig von dem Saugeingang der Pumpe zum Boden 4 des Behälters, der als Rundflasche ausgebildet ist, an deren Flaschenhals die Pumpe 2 befestigt ist.The riser 3 extends straight from the suction inlet of the pump to the bottom 4 of the container, which is designed as a round bottle, at the bottleneck of the pump 2 is attached.

Der Boden 4 der Flasche hat eine besondere Bodenkontur mit einer mittigen Vertiefung 5, in die das freie Ende des Steigrohrs 3 so eingreift, dass das Steigrohr 3 in dieser Lage durch umgebende Wandabschnitt 6 des Bodens gefangen ist. Dabei zeigt Figur 2, dass das freie Ende des Steigrohres 3 vom Boden der Vertiefung 5 ein wenig beabstandet ist, und zwar um einige wenige zehntel Millimeter.The bottom 4 of the bottle has a special bottom contour with a central recess 5, in which engages the free end of the riser 3 so that the riser pipe 3 is caught in this position by surrounding wall portion 6 of the soil. It shows FIG. 2 in that the free end of the riser pipe 3 is slightly spaced from the bottom of the recess 5 by a few tenths of a millimeter.

Die Bodenkontur ist am besten aus den Figuren 2 und 5 ersichtlich. Der die Vertiefung umgebende Bereich 7 des Bodens 4 steigt vom Rand des Bodens aus mit einer geringen Neigung zur Mitte des Bodens hin an, wie Figur 2 deutlich zeigt. In dem Boden ist eine kreuzförmige Vertiefung ausgebildet, die aus zwei streifenförmigen Rinnen 8 besteht, die sich im rechten Winkel kreuzen. Diese Rinnen 8 laufen mit einer geringen Neigung zum mittigen Kreuzungsbereich zu, der die tiefste Stelle bildet und als Vertiefung 5 bezeichnet ist, in die das freie Ende des Steigrohres 3 eingreift. Die die sich kreuzenden streifenförmigen Rinnen 8 umgebenden Bodenbereiche stehen mit im wesentlichen vertikalen Wandabschnitten, die am oberen Rand gerundet sind, über die vertieften Bereiche über.The bottom contour is best from the Figures 2 and 5 seen. The area surrounding the recess 7 of the bottom 4 rises from the edge of the bottom with a slight inclination toward the center of the soil towards how FIG. 2 clearly shows. In the bottom of a cross-shaped recess is formed, which consists of two strip-shaped grooves 8, which intersect at right angles. These grooves 8 run with a slight inclination to the central crossing area, which forms the lowest point and is referred to as a recess 5, in which engages the free end of the riser pipe 3. The intersecting strip-shaped grooves 8 surrounding floor areas are with substantially vertical Wall sections that are rounded at the top, over the recessed areas on.

Bei dieser Ausbildung sammelt sich praktisch die gesamte restliche Flüssigkeitsmenge der Flasche (nachdem nahezu der gesamte Behälterinhalt abgegeben worden ist) in dem vertieften mittigen Bereich 5, da sich auf den schräg zur Mitte ansteigenden Bereichen 7 keine Restmenge der Flüssigkeit dauerhaft ansammeln kann, die statt dessen bei der Handhabung der Flasche in die streifenförmigen Rinnen 8 fließt und sich in deren tiefsten Kreuzungsbereich 5 ansammelt. Von dort kann die Flüssigkeit bis auf eine in der Größe zu vernachlässigende Restmenge von dem Steigrohr angesaugt und aus dem Behälter abgegeben werden.With this design, virtually all of the remaining liquid amount of the bottle (after almost all of the container contents have been dispensed) accumulates in the recessed central area 5, as no residual amount of the liquid can permanently accumulate on the sloping areas 7, which instead flows in the handling of the bottle in the strip-shaped grooves 8 and accumulates in the deepest crossing region 5. From there, the liquid can be sucked up to a negligible in size residual amount of the riser and discharged from the container.

Es wird noch einmal betont, dass die Erfindung nicht auf diese bevorzugte Ausführungsform beschränkt ist. Beispielsweise könnte der Boden vom Flaschenrand aus zur Mitte hin leicht absinken, wobei im mittleren Bereich des Bodens unter dem Steigrohr eine muldenförmige Vertiefung ausgebildet sein kann, die z.B. in der Aufsicht eine Kreisform hat.It is emphasized once again that the invention is not limited to this preferred embodiment. For example, the bottom of the bottom of the bottle could drop slightly towards the center, wherein in the middle region of the bottom under the riser a trough-shaped depression may be formed, which, for example. in the supervision has a circular shape.
