Abstract
Description
Diese Erfindung betrifft eine Sicherheits-Kegverschlusskappe.This invention relates to a safety keg cap.
In Kegs werden derzeit Flüssigkeiten, speziell Getränke, unter Druck transportiert und gelagert. Am Verteilort wird der Behälter installiert und an die Verteilvorrichtung angeschlossen. Bei der Verteilung des Getränkes wird dieses unter Druck aus dem Behälter ausgestossen.Liquids, especially beverages, are currently transported and stored under pressure in kegs. The container is installed at the distribution point and connected to the distribution device. When the beverage is distributed, it is expelled from the container under pressure.
Der Behälter weist einen Austritt auf, an den - ohne Druckverlust - die Verteilvorrichtung anzuschliessen ist; der genannte Austritt ist daher während des Transportes und der Lagerung des Druckbehälters zu schützen.The container has an outlet, to which - without loss of pressure - the distribution device is to be connected; the outlet must therefore be protected during transport and storage of the pressure vessel.
Dieser Schutz sollte, aufgrund auch von allgemeinen Sicherheitsüberlegungen, neben dem Schutz vor Beschädigungen des Austrittes, sowohl die Erstöffnungsgarantie als auch die Möglichkeit des Wiederaufsetzens des Schutzverschlusses umfassen. Diese Aufgabe löst die erfindungsgemässe Sicherheits-Kegverschlusskappe.Due to general safety considerations, this protection should include, in addition to protection against damage to the outlet, both the first opening guarantee and the possibility of putting the protective closure back on. This object is achieved by the safety keg closure cap according to the invention.
Verschlüsse ähnlicher Art sind auch aus der Patentliteratur bekannt:
Der Behälterverschluss gemäss dem US-Patent 4 423 822 ist grundsätzlich ein flüssigkeitsdichter und eventuell auch ein drucksicherer Verschluss. Er weist in allen Ausführungsformen eine Griff- und Oeffnungsklappe auf; diese wird zum Ablösen aus dem Verschluss herausgeklappt (siehe Figur), und derselbe wird durch Anheben an der Klappe vom Behälter gelöst.Closures of a similar type are also known from the patent literature:
The container closure according to US Pat. No. 4,423,822 is basically a liquid-tight and possibly also a pressure-proof closure. It has a handle and in all embodiments Opening flap open; this is folded out of the closure for detachment (see figure), and the same is detached from the container by lifting on the flap.
Demgegenüber ist die erfindungsgemässe Sicherheits-Kegverschlusskappe eine Schutzkappe (über einem mechanischen, dichten Druckverschluss), die aber jedenfalls die Erstöffnung des genannten Druckverschlusses anzeigt (die Klappe im US-Patent kann wieder geschlossen werden). Dazu weist die Sicherheits-Kegverschlusskappe vier oder acht symmetrisch und abgesetzt voneinander angeordnete Keilteile 1.3 auf, von denen abwechslungsweise zwei bzw. vier über Zonen verringerter Reissfestigkeit 1.4 mit dem Verschlusszylinder 1.2 verbunden, d.h. relativ leicht mindestens teilweise davon abtrennbar, sind.In contrast, the safety keg closure cap according to the invention is a protective cap (over a mechanical, tight pressure closure), which in any case indicates the first opening of the said pressure closure (the flap in the US patent can be closed again). For this purpose, the safety keg closure cap has four or eight wedge parts 1.3 arranged symmetrically and offset from one another, of which alternately two or four are connected to the closure cylinder 1.2 alternately by means of tear strength 1.4 which is reduced over zones, i.e. are relatively easily at least partially separable therefrom.
Beim Verschluss gemäss dem genannten US-Patent ist, wie gesagt, nur eine Klappe vorgesehen, und die Anzahl und/oder Anordnung der Untergreifungskeile sowie deren Zuordnung zur Klappe sind alle nicht speziell spezifiziert. In den Zeichnungen (speziell Fig. 4) sind sehr viel mehr Untergreifungsausformungen am festen Deckel angebracht als an der Klappe.As mentioned, only one flap is provided for the closure according to the cited US patent, and the number and / or arrangement of the grip wedges and their assignment to the flap are all not specifically specified. In the drawings (especially Fig. 4), much more underlap formations are attached to the fixed lid than to the flap.
Beim Oeffnen der zwei oder der vier aufreissbaren Keilteile 1.4 an der erfindungsgemässen Sicherheits-Kegverschlusskappe wird der Verschlusszylinder zudem an zwei bis vier regelmässig verteilten Stellen genügend festigkeitsmässig durchschnitten, sodass er relativ leicht vom Behälter abgenommen und wieder darauf aufgesetzt werden kann. Beim Verschluss gemäss dem hier behandelten US-Patent geschieht dies nur an einer Stelle.When opening the two or the four tear-open wedge parts 1.4 on the safety keg closure cap according to the invention, the closure cylinder is also cut through at two to four regularly distributed locations with sufficient strength that it can be removed relatively easily from the container and placed on it again. With the closure according to the US patent dealt with here, this happens only at one point.
Beim ebenfalls flüssigkeitsdichten Behälterverschluss gemäss der GB-A 2 097 768 wird beim Erstöffnen desselben die einzige Abreisslasche 18 entlang den Sollreisslinien 22 und 24 den ganzen Verschlussmantel hinauf und entlang den Fortsetzungs-Sollreisslinien 26 und 28 rund um die Verschlussdeckel-Peripherie aufgerissen (siehe Figuren 1 und 2).With the likewise liquid-tight container closure according to GB-
Durch das Aufreissen der Lasche 18 und das Abreissen des Deckelteils 10 fällt der Verschluss auseinander (ohne in mehrere Teile zu zerfallen); er kann dann nicht wiederverwendet werden (S. l, Z. 98 ff).By tearing open the tab 18 and tearing off the cover part 10, the closure falls apart (without disintegrating into several parts); it cannot then be reused (p. 1, lines 98 ff).
Bei den Verschlusskappen gemäss der DE-U 84 14 651 werden beim Aufreissen der Sperrelemente entweder diese offensichtlich alle abgerissen (Fig. 1) oder die Kappe wird in 2 Teile getrennt (Fig. 2). Rückhalte-Elemente wie die nicht-abgelösten Keilteile bei der geöffneten erfindungsgemässen Kegverschlusskappe sind nicht mehr vorhanden.In the closure caps according to DE-U 84 14 651, when the blocking elements are torn open, all of them are obviously torn off (FIG. 1) or the cap is separated into two parts (FIG. 2). Retaining elements such as the undetached wedge parts when the inventive keg closure cap is open are no longer present.
Im Gegensatz zu den angegebenen Lösungen gemäss dem Stand der Technik erlaubt es die erfindungsgemässe Sicherheits-Kegverschlusskappe - auch für den Fachmann nicht ohne weiteres voraussehbar -
- ohne Abreisslappen und somit ohne Materialverlust bei der Erstöffnung auszukommen, sowie
- in einer technisch stark vereinfachten Form allen drei Anforderungen, d.h. derjenigen nach dem mechanischen Schutz des Austrittes, derjenigen nach der Erstöffnungsgarantie und derjenigen der Wiederverwendung,
- without tear-off tabs and thus without material loss when opening for the first time, and
- in a technically highly simplified form all three requirements, ie those for mechanical protection of the outlet, those for the first opening guarantee and those for reuse,
Eine Lösung ohne Abtrennung von Verschlussteilen ist zudem offensichtlich ökologischer, zumal heute das Wieder-Einschmelzen von Formteilen aus Polyolefinen ein technisch gelöstes Problem ist.A solution without separating the closure parts is also obviously more ecological, especially since the remelting of molded parts made of polyolefins is a technically solved problem.
Die erfindungsgemässe Sicherheits-Kegverschlusskappe für auf Flüssigkeits-Druckbehälter, die Verschlusskappe mit Verschlussdeckel und Verschlusszylinder sowie mit an der Innenwand des Verschlusszylinders angebrachten, vom Verschlussdeckel abgesetzt angeordneten, in den Behälter-Oberrand einrastenden Keilteilen, ist dadurch gekennzeichnet, dass vier oder acht symmetrisch angeordnete Keilteile vorgesehen sind, von denen abwechslungsweise zwei bzw. vier über Zonen mit verringerter Reissfestigkeit (1.4) mit dem Verschluss verbunden sind, wobei die genannten Zonen vom unteren Rand des Verschlusszylinders ausgehen.The safety keg closure cap according to the invention for on liquid pressure containers, the closure cap with the closure cover and the closure cylinder and with wedge parts which are attached to the inside wall of the closure cylinder and are arranged at a distance from the closure cover and snap into the upper edge of the container is characterized in that four or eight symmetrically arranged wedge parts are provided, of which two or four are alternately connected to the closure via zones with reduced tensile strength (1.4), the zones mentioned starting from the lower edge of the closure cylinder.
Die genannten Zonen mit verringerter Reissfestigkeit sind bevorzugterweise in Form von Stegen/Hohlräumen zwischen den Keilteilen und dem Verschlusszylinder ausgebildet, wobei jeweils ein Steg verstärkt ausgeführt ist, wodurch - beim Aufreissen der genannten Zonen - der Keilteil sich nicht vollständig vom Verschluss löst.Said zones with reduced tear strength are preferably designed in the form of webs / cavities between the wedge parts and the locking cylinder, each web being reinforced, as a result of which, when the said zones are torn open, the wedge part does not completely detach from the closure.
Die Keilportionen schliessen dabei mit Vorteil einen Kreisbogenwinkel des Verschlusszylinders von ca. 20° bzw. von ca. 40° ein.The wedge portions advantageously include a circular arc angle of the locking cylinder of approximately 20 ° or approximately 40 °.
Die genannte Sicherheits-Kegverschlusskappe besteht aus druckspritzbaren Elastomeren, speziell Polyolefinen, bevorzugterweise Polyäthylen oder Polypropylen.The safety keg closure cap mentioned consists of pressure-sprayable elastomers, especially polyolefins, preferably polyethylene or polypropylene.
Die erfindungsgemässe Sicherheits-Kegverschlusskappe wird nun anhand der Ausführungsform gemäss den beiliegenden Figuren 1 und 2 beispielhaft im Detail beschrieben. Dabei stellen die Figuren folgendes dar:
- Fig. 1a: Schnittdarstellung der erfindungsgemässen Sicherheits-Kegverschlusskappe gemäss dem Patentanspruch 3 (Schnitt durch Achse);
- Fig. 1b: Oben- und Durchsichtsdarstellung der gleichen Sicherheits-Kegverschlusskappe;
- Fig. 1c: An- und Durchsichtsdarstellung derselben Sicherheits-Kegverschlusskappe;
- Fig. 2: Schnittdarstellung (schematisch) des Austritts-Halses eines Flüssigkeits-Druckbehälters.
- Fig. 1a: sectional view of the safety keg closure cap according to the invention according to claim 3 (section through axis);
- 1b: top and see-through representation of the same safety keg closure cap;
- 1c: View and see-through representation of the same safety keg closure cap;
- Fig. 2: sectional view (schematic) of the outlet neck of a liquid pressure vessel.
Die Figur 1a zeigt, wie gesagt, eine schematische Darstellung im Schnitt durch die Achse der erfindungsgemässen Sicherheits-Kegverschlusskappe mit vier Keilabschnitten; die Grössenverhältnisse entsprechen nicht den tatsächlichen. Am Verschlussdeckel 1.1 schliesst der Verschlusszylinder 1.2 an. Die Keilteile 1.3 sind an der Innenseite des Verschlusszylinders, versetzt vom Verschlussdeckel, angebracht. Die Keile sind so ausgebildet, dass sie unter der Endverdickung des Halses um den Behälteraustritt einrasten.As said, FIG. 1a shows a schematic illustration in section through the axis of the safety keg closure cap according to the invention with four wedge sections; the proportions do not correspond to the actual ones. The closing cylinder 1.2 connects to the closing cover 1.1. The wedge parts 1.3 are attached to the inside of the lock cylinder, offset from the cover. The wedges are designed so that they snap under the final thickening of the neck around the container outlet.
In der Oben- und Durchsichtsdarstellung gemäss der Figur 1b sind der Verschlusszylinder 1.2 und die vier Keil-Teile 1.3 ersichtlich.In the top and see-through representation according to FIG. 1b, the locking cylinder 1.2 and the four wedge parts 1.3 can be seen.
In der Figur 1c, d.h. in der An- und Durchsichtsdarstellung der gesamten Sicherheits-Kegverschlusskappe gemäss dem Patentanspruch 3, sind wiederum der Verschlusszylinder 1.2 und zwei Keil-Teile 1.3 ersichtlich (die andern zwei Keil-Teile sind nicht eingezeichnet). Um den in der Figur rechts dargestellten Keil-Teil ist eine Zone verringerter Reissfestigkeit 1.4 dargestellt. Diese kann z.B. mittels Stegen/Hohlräumen oder auch mittels verringerter Wandstärke realisiert sein. In beiden Fällen wäre aber darauf zu achten, dass zumindest an einer Stelle der Zone verringerter Reissfestigkeit ein Steg, bzw. ein Abschnitt der Verbindungswand, die übliche Stärke aufweist, sodass der Keilteil, nach dem Aufreissen der Zone verringerter Reissfestigkeit, an der genannten Stelle mit dem Verschluss verbunden bleibt. Auch nach dem erstmaligen Oeffnen des erfindungsgemässen Sicherheits-Kegverschlusses verbleibt dieser also an einem Stück. Die Zonen verringerter Reissfestigkeit gehen ersichtlicherweise vom unteren Rand des Verschlusszylinders aus.In Figure 1c, i.e. in the view and see-through representation of the entire safety keg closure cap according to claim 3, the closure cylinder 1.2 and two wedge parts 1.3 are again visible (the other two wedge parts are not shown). A zone of reduced tensile strength 1.4 is shown around the wedge part shown on the right in the figure. This can e.g. by means of webs / cavities or also by means of reduced wall thickness. In both cases, however, it would be important to ensure that at least at one point in the zone of reduced tensile strength, a web, or a section of the connecting wall, has the usual thickness, so that the wedge part, after tearing open the zone of reduced tensile strength, is also present at the point mentioned remains connected to the closure. Even after the safety keg closure according to the invention has been opened for the first time, it therefore remains in one piece. The zones of reduced tensile strength evidently start from the lower edge of the locking cylinder.
Die Figur 2 schliesslich zeigt einen schematischen Schnitt durch die Längsachse des Austrittshalses 2 am Flüssigkeits-Druckbehälter. Mit 2.1 ist der eigentliche Behälterhals und mit 2.2 ein rundum keilförmig verstärkter Halsabschluss bezeichnet. Der genannte Abschluss braucht nicht speziell keilfömig zu sein, er kann auch eine Halbrundung o.ä. sein. Jedenfalls sind solche Abschlüsse derart ausgebildet, dass die Verschlusskappe mittels Keilteilen o.ä. darunter verankert werden kann.Finally, FIG. 2 shows a schematic section through the longitudinal axis of the
Aus der genannten Darstellung folgt auch, dass die erfindungsgemässe Sicherheits-Kegverschlusskappe nach dem erstmaligen Oeffnen, d.h. nach dem Aufreissen der Zonen, wieder auf den Austrittshals des Flüssigkeits-Druckbehälters aufgebracht werden kann, wo sie weiterhin Bedeckungsfunktion und Schutz vor mechanischen Einwirkungen auf den Druckanschlussteil ausübt.From the illustration mentioned it also follows that the safety keg closure cap according to the invention after the first opening, i.e. after the zones have been torn open, it can be applied again to the outlet neck of the liquid pressure vessel, where it continues to have a covering function and protection against mechanical influences on the pressure connection part.
Die oben beschriebene erfindungsgemässe Keg-Verschlusskappe kann selbstverständlich innerhalb des fachmännischen Optimierungsvermögens abgeändert werden, ohne damit aus dem Patentbereich zu fallen. Z.B. kann der Keilteil in Form von einzelnen kleinen Keilen realisiert werden (Materialeinsparung).The above-described keg closure cap according to the invention can of course be modified within the scope of technical optimization without falling outside the scope of the patent. E.g. the wedge part can be realized in the form of individual small wedges (material saving).
