Description

Im Hinblick auf möglichst hohe Festigkeit bei niedrigem Gewicht werden die Griffstege oder Griffränder von Flaschenkästen traditionell mit U- oder E-förmigem profil hergestellt. Dabei weisen die Profilschenkel üblicherweise nach außen, können aber auch im Interesse eines möglichst glattflächigen Kastens nach innen gerichtet sein. Durch eine solche Verrippung sind die Griffstege schmutzanfällig und lassen sich schlechter greifen als ein Vollprofil. Man hat daher auch schon versucht, die Öffnung eines U-Profils mit Lamellen auszufüllen. Dadurch steigt aber die Schmutzanfälligkeit, ohne daß die Griffigkeit entscheidend verbessert wird.With regard to the highest possible strength and low weight, the handle bars or grip edges of bottle crates are traditionally made with a U- or E-shaped profile. The profile legs usually point outwards, but can also be directed inwards in the interest of a box with as smooth a surface as possible. Such ribbing means that the handle bars are prone to dirt and are harder to grip than a full profile. Attempts have therefore already been made to fill the opening of a U-profile with lamellas. This increases the susceptibility to dirt without significantly improving the grip.

Aus der GB-A-1 159 733 ist ein Kasten zum Transport von Fischen beschrieben. Der Aufbau des Kastens besteht aus Kunststoff, wobei sich jeweils zwei gleichartig ausgebildete Seitenwände gegenüberstehen und über Eckstützen miteinander verbunden sind. Die Seitenteile weisen im Bereich der Eckstützen und in Teilbereichen der Seitenwände durchgehende vertikale Ausnehmungen auf, während die dazwischenliegenden Bereiche der Seitenwände aus Vollmaterial bestehen. Zur Versteifung des Kastens sind in den Hohlräumen entweder Blöcke aus Holz oder Zapfen vorgesehen, welche die Ausnehmungen teilweise oder vollständig ausfüllen. Die Blöcke und Zapfen sind mit einer Abdeckung abgesichert, die über die Ausnehmungen hinausragen kann.GB-A-1 159 733 describes a crate for transporting fish. The structure of the box is made of plastic, with two identical side walls facing each other and connected to each other via corner supports. The side parts have continuous vertical recesses in the area of the corner supports and in partial areas of the side walls, while the intermediate areas of the side walls consist of solid material. To stiffen the box, either blocks of wood or pins are provided in the cavities, which partially or completely fill the recesses. The blocks and pins are secured with a cover that can protrude beyond the recesses.

Aus der FR-A-2 177 008 ist ein Flaschenkasten aus Kunststoff bekannt, dessen hohle Eckstützen im oberen und unteren Bereich durch Verbindungselemente zu einem Oberrahmen mit Griffstegen bzw. einem Unterrahmen verbunden sind. Die Verbindungselemente bilden ein U-förmiges, auf drei Seiten geschlossenes, dem Kastenboden zugewandtes Hohlprofil mit etwa rechteckigem oder quadratischem Querschnitt.From FR-A-2 177 008 a bottle crate made of plastic is known, the hollow corner supports in the upper and the lower area are connected by connecting elements to form an upper frame with handle bars or a lower frame. The connecting elements form a U-shaped hollow profile, closed on three sides and facing the box bottom, with an approximately rectangular or square cross section.

Der Erfindung liegt die Aufgabe zugrunde, einen Flaschenkasten aus Kunststoff zu schaffen, der bei hoher Festigkeit und niedrigem Gewicht seiner Profile insbesondere im Griffbereich möglichst glattflächig ist.The invention has for its object to provide a bottle crate made of plastic, which is as smooth as possible with high strength and low weight of its profiles, especially in the grip area.

Die Lösung der Aufgabe ist im Anspruch 1 angegeben.The solution to the problem is specified in claim 1.

Hohlprofile besitzen in bekannter Weise hohe Festigkeit auch bei kleiner Wandstärke. Dadurch, daß das Hohlprofil zunächst auf einer Seite offen ist, läßt es sich ohne komplizierte Formen zusammen mit dem Flaschenkasten einstückig im Spritzgußverfahren herstellen. Erst anschließend wird das Hohlprofil mit der Abdeckplatte durch Ultraschallschweißung oder Kleben verschlossen. Dadurch kann eine hohe Festigkeit erreicht werden. Außerdem erfolgt ein wasserdichter Verschluß des Hohlprofils.In a known manner, hollow profiles have high strength even with small wall thickness. Because the hollow profile is initially open on one side, it can be produced in one piece in an injection molding process together with the bottle crate without complicated shapes. Only then is the hollow profile closed with the cover plate by ultrasonic welding or gluing. This enables high strength to be achieved. In addition, the hollow profile is sealed watertight.

Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche. So kann vorzugsweise die Abdeckplatte für die Griffstege auf deren Oberseite angeordnet sein. Die Spritzgußform ist dann am einfachsten. Aus dem gleichen Grund wird zweckmäßig die Abdeckplatte für die Wände im unteren Bereich des Kastens auf der Unterseite vorgesehen.Developments of the invention are the subject of the dependent claims. For example, the cover plate for the handle bars can preferably be arranged on the upper side thereof. The injection mold is then the simplest. For the same reason, the cover plate for the walls in the lower region of the box is expediently provided on the underside.

Die Abdeckplatten können jeweils nur im Bereich der Griffstege bzw. Wände zwischen den Eckstützen angeordnet sein. Es besteht aber auch die Möglichkeit, daß die Abdeckplatten auf der Oberseite der Griffstege bis in die Kastenecken reichen und dort vorzugsweise auf Gehrung aneinanderstoßen. Eine solche Ausbildung kommt insbesondere dann in Frage, wenn in bekannter Weise Eckstützen in Form von Hohlsäulen verwendet werden. Die Abdeckplatten verschließen dann die Hohlsäulen an ihrem oberen Ende. Dadurch können die Ecksäulen bei einfacher Ausbildung der Spritzgußform als durchgehende Hohlprofile unter genauer Einhaltung gleichmäßiger Wandstärken hergestellt werden.The cover plates can only be arranged in the area of the handle bars or walls between the corner supports. But there is also the possibility that the cover plates on the top of the handle bars extend into the box corners and preferably meet there with a miter. Such training is coming in particular when corner supports in the form of hollow columns are used in a known manner. The cover plates then close the hollow columns at their upper end. As a result, the corner pillars can be produced as a continuous hollow profile with a simple design of the injection mold, with exact adherence to uniform wall thicknesses.

Statt getrennter Abdeckplatten kann auch für alle vier Kastenseiten ein geschlossener Rahmen verwendet werden. Ein solcher Rahmen läßt sich zur Erzielung besonderer optischer Wirkungen auch andersfarbig gestalten sowie auch aus anderem Material als der übrige Kasten herstellen.Instead of separate cover plates, a closed frame can also be used for all four box sides. Such a frame can also be designed in a different color to achieve special optical effects and can also be made from a different material than the rest of the box.

Zur Versteifung der Hohlprofile kann vorgesehen sein, daß im Inneren des Profils Querversteifungen angeordnet sind. In gleicher Weise können auch die Abdeckplatten mit zum Profilinneren weisenden Querrippen versehen sein. Um zu vermeiden, daß die Hohlprofile sich nach dem Entformen nach innen einbeulen, können die Abdeckplatten an beiden Längsrändern derart mit zum Profilinneren weisenden Einführungsrippen versehen sein, daß die Wände des Hohlprofils beim Eindrücken der Abdeckplatten auf den richtigen Abstand gebracht werden.To stiffen the hollow profiles, it can be provided that transverse stiffeners are arranged in the interior of the profile. In the same way, the cover plates can also be provided with transverse ribs pointing towards the inside of the profile. In order to prevent the hollow profiles from bulging inwards after removal from the mold, the cover plates can be provided on both longitudinal edges with insertion ribs pointing towards the inside of the profile in such a way that the walls of the hollow profile are brought to the correct distance when the cover plates are pressed in.

Der in Fig. 1 schematisch im Bereich einer Ecke dargestellte Flaschenkasten aus Kunststoff besitzt nach außen glattflächige hohle Ecksäulen 1 mit etwa dreieckigem (oder auch rechteckigem), zum Kasteninneren gerundeten Querschnitt. Die Ecksäulen sind am Kastenoberrand durch Griffstege 2 verbunden, die, wie die Querschnittsansichten gemäß Fig. 4 bis 6 zeigen, im Querschnitt die Form eines nach oben offenen U besitzen. Im unteren Bereich sind die Kastenecken durch nicht im einzelnen dargestellte Doppelwände 3 verbunden, die ebenfalls die Form eines in diesem Fall nach unten offenen U haben können. Zwischen den Griffstegen 2 und den Wänden 3 befinden sich jeweils Eingriffsöffnungen 4.The plastic bottle crate shown schematically in FIG. 1 in the area of a corner has hollow corner pillars 1 with a smooth surface on the outside, with an approximately triangular (or also rectangular) cross section that is rounded toward the inside of the crate. The corner pillars are connected at the top of the box by handle bars 2 which, as the cross-sectional views according to FIGS. 4 to 6 show, have the shape of a U open at the top in cross section. In the lower area, the box corners are connected by double walls 3, not shown in detail, which can also have the shape of a U open in this case. There are engagement openings 4 between the handle bars 2 and the walls 3.

Nach der Herstellung eines Flaschenkastens gemäß Fig. 1 im üblichen Spritzgußverfahren werden die oben offenen Griffstege 2 mittels Abdeckplatten 5 verschlossen. Die Abdeckplatten werden durch Ultraschallschweißen oder Kleben dauerhaft und zuverlässig festgefügt, und zwar derart, daß das Profil der Griffstege 2 wasserdicht verschlossen ist.After the production of a bottle crate according to FIG. 1 in the usual injection molding process, the handle webs 2 which are open at the top are closed by means of cover plates 5. The cover plates are permanently and reliably attached by ultrasonic welding or gluing, in such a way that the profile of the handle bars 2 is sealed watertight.

Bei der Abwandlung gemäß Fig. 2 reichen die Abdeckplatten 5 bis in die Kastenecke und stoßen dort auf Gehrung aneinander. Dadurch können die Ecksäulen bzw. Eckbereiche 1 als durchgehende Hohlprofile hergestellt werden, die dann nach dem Spritzen des Kastens ebenso wie die Griffstege 2 mittels der Abdeckplatten 5 verschlossen werden. Anstelle der einzelnen Abdeckplatten 5 wird bei dem Ausführungsbeispiel gemäß Fig. 3 ein geschlossener Rahmen 15 verwendet, der den gesamten Kastenoberrand, also sowohl die Griffstege 2 als auch die Eckbereiche 1, nach oben abschließt. Zur Erzielung besonderer Effekte kann der Rahmen 1 aus anderem oder andersfarbigem Material als der Kasten hergestellt sein. Gleiches gilt auch für die einzelnen Abdeckplatten 5.In the modification according to FIG. 2, the cover plates 5 extend into the box corner and there are mitred against one another. As a result, the corner pillars or corner areas 1 can be produced as continuous hollow profiles which, like the handle webs 2, are then closed by means of the cover plates 5 after the injection molding of the box. Instead of the individual cover plates 5, a closed frame 15 is used in the exemplary embodiment according to FIG. 3, which closes the entire top edge of the box, that is to say both the handle bars 2 and the corner regions 1, at the top. To achieve special effects, the Frame 1 made of a different or different colored material than the box. The same applies to the individual cover plates 5.

Fig. 4 zeigt in Form von Querschnitten im einzelnen, wie der Griffsteg 2 und seine Abdeckplatte 5 ausgebildet sind. Die Abdeckplatte 5 ist auf der Oberseite leicht gerundet und besitzt an beiden Rändern zum Inneren des Griffstegs weisende Längsrippen 6 auf. Am Außenrand der Abdeckplatte 5 sind außerdem zur Erzielung einer guten und dichten Ultraschallschweißung Wülste 7 vorgesehen. Die Längsrippen 6 drücken nach dem Aufsetzen der Abdeckplatte 5 die Wände des Griffsteges 2 in die richtige Lage. Danach erfolgt die wasserdichte Ultraschallschweißung mit Hilfe bekannter Verfahren und Vorrichtungen. Der untere Teil in Fig. 4 zeigt den hohlen Griffsteg 2 nach der Verschweißung.Fig. 4 shows in the form of cross sections in detail how the handle bar 2 and its cover plate 5 are formed. The cover plate 5 is slightly rounded on the top and has longitudinal ribs 6 pointing towards the inside of the handle web on both edges. On the outer edge of the cover plate 5 beads 7 are also provided to achieve a good and tight ultrasonic welding. The longitudinal ribs 6 press the walls of the handle bar 2 into the correct position after the cover plate 5 has been put on. The waterproof ultrasonic welding is then carried out using known methods and devices. The lower part in Fig. 4 shows the hollow handle bar 2 after welding.

Zur Versteifung ist die Abdeckplatte 5 mit Querrippen 8 versehen, wie auch in Fig. 1 und 2 gezeigt. Weitere Querrippen (nicht dargestellt) können auch im Inneren der Profile 2 vorgesehen sein und bewirken dann ebenfalls eine Versteifung.For stiffening, the cover plate 5 is provided with transverse ribs 8, as also shown in FIGS. 1 and 2. Further transverse ribs (not shown) can also be provided in the interior of the profiles 2 and then also bring about stiffening.

Das Ausführungsbeispiel gemäß Fig. 5 zeigt ein gegenüber dem Ausführungsbeispiel nach Fig. 4 abgewandeltes Querschnittsprofil des Griffsteges 2 und seiner Abdeckplatte 5. Auch hier erfolgt wiederum eine Festlegung der Abdeckplatte 5 mittels Ultraschallschweißung.The exemplary embodiment according to FIG. 5 shows a cross-sectional profile of the handle bar 2 and its cover plate 5 which is modified compared to the exemplary embodiment according to FIG. 4. Here too the cover plate 5 is fixed by means of ultrasonic welding.

Bei allen Ausführungsbeispielen können auf der Unterseite der Griffstege 2 kleine Bohrungen (nicht gezeigt) vorgesehen sein, die ein Ablaufen von sich gegebenenfalls bildendem Schwitzwasser ermöglichen.In all of the exemplary embodiments, 2 small bores (not shown) can be provided on the underside of the handle bars, which allow any condensation water that may form to run off.

Die Griffstege 2 können insbesondere im Griffbereich auf der Unterseite gerundet oder auch auf andere Weise gestaltet sein, um die Griffigkeit zu verbessern.The grip bars 2 can be rounded in particular in the grip area on the underside or can be designed in another way in order to improve the grip.
