Description

Die Erfindung betrifft öffnungshilfen für Ampullen, die ein sicheres und gefahrloses öffnen der Ampullen gewährleisten und gleichzeitig ein rasches, verlustfreies überführen des gesamten Ampulleninhalts in ein Gefäß, z. B. einen Meßkolben oder ein Becherglas, ermöglichen.The invention relates to opening aids for ampoules, which ensure a safe and safe opening of the ampoules and at the same time a quick, loss-free transfer of the entire ampoule content into a vessel, for. B. allow a volumetric flask or a beaker.

Bei den zu öffnenden Ampullen handelt es sich vor allem um Kunststoffampullen mit konzentrierten Lösungen zur Herstellung von Maß-, Standard- und Pufferlösungen. Die wohl bekanntesten öffnungshilfen für diese Ampullen sind Glasstäbe. Im Sinne des Gerätesicherheitsgesetzes handelt es sich beim Glasstab um ein Gerät, das Gefahren in sich birgt. Beim Benutzen der bis zu 30 cm langen Glasstäbe können diese aus unterschiedlichen Gründen durchbrechen und die nachdrückende Hand gerät in den gesplitterten Glasstumpf.The ampoules that can be opened are primarily plastic ampoules with concentrated solutions for the production of standard, standard and buffer solutions. The most well-known opening aids for these ampoules are glass rods. In the sense of the device safety law, the glass rod is a device that carries dangers. When using the up to 30 cm long glass rods, they can break through for different reasons and the pressing hand gets into the splintered glass stump.

Eine bekannte Weiterentwicklung sind kunststoffummantelte Glasstäbe; diese besitzen jedoch eine Reihe von Nachteilen: Das Ablaufverhalten von Wasser und wäßrigen Lösungen ist ungünstig; die Ummantelung kann sich an der Übergangsstelle Glas/Kunststoff ablösen; diese Glasstäbe sind unverhältnismäßig teuer.A well-known further development are plastic-coated glass rods; however, these have a number of disadvantages: the runoff behavior of water and aqueous solutions is unfavorable; the casing can peel off at the glass / plastic transition point; these glass rods are disproportionately expensive.

Kunststoff- und Metallstäbe scheiden aus Gründen der Stabilität gegen die in der Maßanalyse benutzten Reinigungsmittel (ethanolische Kalilauge oder Chromschwefelsäure) für eine wiederholte Verwendung aus. Der Metallstab ist außerdem für Arbeiten auf dem Gebiet der Spurenanalytik von Metallen nicht zu gebrauchen,-da er die Standardlösungen verunreinigt.For reasons of stability, plastic and metal rods are excluded from the cleaning agents used in the dimensional analysis (ethanolic potassium hydroxide solution or chromosulfuric acid) for repeated use. The metal rod is also unusable for work in the field of trace analysis of metals, since it contaminates the standard solutions.

Eine weitere auf dem Markt befindliche öffnungshilfe für Ampullen ist ein Plastikmesser. Aber auch dieses Hilfsmittel ist mit Nachteilen behaftet: Verlust des Ampulleninhaltes, da das Messer nicht abgespült werden kann; Verlust des Ampulleninhaltes beim Umdrehen der einseitig geöffneten Ampulle; steckt man den Meßkolben vor dem Umdrehen auf die Ampulle und dreht beides gemeinsam um, so besteht die Gefahr, daß der Meßkolben bei dieser umständlichen Operation zu Bruch geht; bei zu kleiner öffnung am Ampullenende läuft der Inhalt sehr langsam aus und beim Ausspülen der Ampulle ergeben sich Schwierigkeiten.Another opening aid for ampoules on the market is a plastic knife. However, this aid also has disadvantages: loss of the ampoule content because the knife cannot be rinsed off; Loss of ampoule contents when the ampoule opened on one side is turned over; if you place the volumetric flask on the ampoule before turning it around and turn both around together, there is a risk that the volumetric flask will break during this cumbersome operation; If the opening at the end of the ampoule is too small, the contents run out very slowly and there are difficulties when rinsing the ampoule.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, öffnungshilfen zur Verfügung zu stellen, die eine rasche und quantitative Entleerung des Ampulleninhalts bei geringem nachfolgendem Ausspülen ermöglichen und mit denen die oben geschilderten Nachteile nicht auftreten.The present invention has for its object to provide opening aids that allow rapid and quantitative emptying of the ampoule contents with little subsequent rinsing and with which the disadvantages described above do not occur.

Gegenstand der Erfindung sind öffnungshilfen für mit Kunststoffmembranen (1) verschlossene Ampullen (2), die dadurch gekennzeichnet sind, daß sie als Hülsen (3) ausgebildet sind, die im Innern eine als Schneide (5) ausgebildete Vorrichtung (4) enthalten. Die Hülsen (3) haben vorzugsweise die Form eines Trichters, wobei sich die Vorrichtung (4) im röhrenförmigen Teil des Trichters befindet.The invention relates to opening aids for ampoules (2) sealed with plastic membranes (1), which are characterized in that they are designed as sleeves (3) which contain a device (4) designed as a cutting edge (5) on the inside. The sleeves (3) preferably have the shape of a funnel, the device (4) being located in the tubular part of the funnel.

Die Vorrichtung (4) ist vorzugsweise als inneres Rohr ausgebildet, das an einem Ende entweder über den gesamten Umfang oder über Stege (6) mit der Hülse (3) verbunden ist. Das andere Ende des inneren Rohrs ist sowohl über den gesamten Umfang als auch von außen nach innen abgeschrägt und stellt damit eine wirkungsvolle Schneide (5) dar. Die Schneiden können auch mit der Kunststoffmembran (1) so verschweißt sein, daß bereits ein Drehen der Hülse (3) ein Zerreißen der Kunststoffmembran (1) bewirkt.The device (4) is preferably designed as an inner tube which is connected at one end to the sleeve (3) either over the entire circumference or via webs (6). The other end of the inner tube is chamfered both over the entire circumference and from the outside inwards and thus represents an effective cutting edge (5). The cutting edges can also be welded to the plastic membrane (1) in such a way that the sleeve is already rotating (3) causes the plastic membrane (1) to tear.

In der Abbildung 1 ist eine bevorzugte Ausführungsform der Ampulle mit den erfindungsgemäßen öffnungshilfen dargestellt. Mit (1) ist die Kunststoffmembran, mit (2) die Ampulle, mit (3) die Hülse, mit (4) die als Schneide ausgebildete Vorrichtung, mit (5) die Schneide, mit (6) die Stege, mit (7) das Gewinde und mit (8) der Ampullenhals bezeichnet. Abbildung 2 zeigt einen Querschnitt durch die Hülse (3), wobei die Stege (6) erkennbar sind. Wie aus der Abbildung 1 hervorgeht, können die Ampullenhälse (8) und entsprechend auch die zugehörigen Hülsen (3) unterschiedliche Durchmesser haben, vorzugsweise hat der an der Auslaufstelle der Ampulle sitzende Hals (8) einen solchen Durchmesser, daß der Ampulleninhalt auch in Meßkolben mit Normschliff NS 14/23 entleert werden kann.1 shows a preferred embodiment of the ampoule with the opening aids according to the invention. With (1) the plastic membrane, with (2) the ampoule, with (3) the sleeve, with (4) the device designed as a cutting edge, with (5) the cutting edge, with (6) the webs, with (7) the thread and (8) the ampoule neck. Figure 2 shows a cross section through the sleeve (3), the webs (6) being recognizable. As can be seen from Figure 1, the ampoule necks (8) and, accordingly, the associated sleeves (3) can have different diameters, preferably the neck (8) located at the outlet point of the ampoule has a diameter such that the ampoule contents are also in volumetric flasks Standard ground joint NS 14/23 can be emptied.

Alle Teile der Ampulle und der erfindungsgemäßen öffnungshilfen bestehen aus Kunststoffen wie Polyethylen, Polypropylen, Polyvinylidendifluorid oder Methylpenten-Polymeren. Die Abmessungen können entsprechend den gewünschten Flüssigkeitsmengen gewählt werden. Eine 100 cm3 fassende Ampulle ist z. B. einschließlich der röhrenförmigen Ansätze etwa 160-200 mm lang und hat einen Durchmesser von etwa 25-35 mm.All parts of the ampoule and the opening aids according to the invention consist of plastics such as polyethylene, polypropylene, polyvinylidene difluoride or methylpentene polymers. The dimensions can be chosen according to the desired amount of liquid. A 100 cm 3 ampoule is z. B. including the tubular approaches about 160-200 mm long and has a diameter of about 25-35 mm.

Zum öffnen der Ampulle werden zwei der erfindungsgemäßen öffnungshilfen entsprechend der Abbildung 1 auf die Ampulle aufgesetzt. Die untere öffnungshilfe wird anschließend auf einen Meßkolben aufgesetzt, und die Kunststoffmembranen (1) werden durch Eindrücken oder Eindrehen der Hülsen (3) auf- bzw. abgeschnitten. In einer bevorzugten Ausführungsform wird die untere Kunststoffmembran durch Eindrehen der Hülse (3) geöffnet. Zu diesem Zweck ist der Ampullenkörper mit einem Gewinde (7) versehen, das aufgrund seines Profils und seines Profilquerschnittes eine einwandfreie und zuverlässige Führung auf der mit einem entsprechenden Gegengewinde versehenen Hülse (3) erlaubt. Auf diese Weise wird die Drehbewegung in eine axiale Bewegung umgesetzt. Die obere Kunststoffmembran wird vorzugsweise durch Eindrücken geöffnet, wobei die öffnungshilfe als Schiebehülse (3) auf dem Ampullenhals (8) in axialer Richtung geführt wird. Es ist natürlich möglich, auch die obere öffnungshilfe mit einem Gewinde zum Eindrehen zu versehen. Die gleiche Funktion wie das Gewinde kann eine Führungsnut erfüllen.To open the ampoule, two of the opening aids according to the invention, as shown in FIG. 1, are placed on the ampoule. The lower opening aid is then placed on a volumetric flask, and the plastic membranes (1) are cut or cut by pushing in or screwing in the sleeves (3). In a preferred embodiment, the lower plastic membrane is opened by screwing in the sleeve (3). For this purpose, the ampoule body is provided with a thread (7) which, owing to its profile and its profile cross section, permits perfect and reliable guidance on the sleeve (3) provided with a corresponding counter thread. In this way, the rotary movement is converted into an axial movement. The upper plastic membrane is preferably opened by being pressed in, the opening aid being guided in the axial direction as a sliding sleeve (3) on the ampoule neck (8). Of course it is also possible to provide the upper opening aid with a screw thread. A guide groove can perform the same function as the thread.

Die Hülse (3) enthält ein inneres Rohr, dessen Ende zu einer scharfkantigen Schneide (5) ausgebildet ist. Dieses Rohr ist vorzugsweise an 2-6 Stellen über Stege mit der Hülse (3) verbunden, so daß ein Hochsteigen des Ampulleninhaltes zwischen der Außenseite des Ampullenhalses und dem inneren Rohr bei der Entleerung verhindert wird.The sleeve (3) contains an inner tube, the end of which is formed into a sharp-edged cutting edge (5). This tube is preferably connected to the sleeve (3) at 2-6 points via webs, so that the contents of the ampoule rise up between the outside of the ampoule neck and the inner tube during emptying.

Zur Transportsicherung können die öffnungshilfen umgekehrt auf die Ampulle aufgesetzt werden, so daß die Schneide (5) von der Kunststoffmembran (1) abgewandt ist. Werden öffnungshilfen verwendet, die über ein Gewinde (7) eine Drehbewegung in eine axiale Bewegung umsetzen, so können zwei umlaufende ringförmige Wülste auf dem röhrenförmigen Ansatz der Ampulle, die einen entsprechenden Wulst im Aufstecktrichter halten, eine Sperre bilden. Durch kräftiges Drehen kann diese Sperre überwunden werden; eine Überwindung durch senkrecht einwirkende Kräfte, wie z. B. beim Herabfallen der Ampulle, ist nicht möglich. Andere Möglichkeiten der Transportsicherung sind z. B. Bajonettverschlüsse oder eine Abreißlasche, die vor dem Eindrehen entfernt werden muß. Die erfindungsgemäße öffnungshilfe gewährleistet ein gefahrloses öffnen der Ampulle und ein rasches, vollständiges und verlustfreies Uberführen des Ampulleninhalts in einen Meßkolben oder in ein Becherglas. Zur öffnung der Ampulle sind keine weiteren eventuell gefährlichen oder den Ampulleninhalt beeinträchtigenden Hilfsmittel erforderlich.To secure transport, the opening aids can be placed conversely on the ampoule so that the cutting edge (5) faces away from the plastic membrane (1). If opening aids are used which convert a rotary movement into an axial movement via a thread (7), two circumferential annular beads on the tubular extension of the ampoule, which hold a corresponding bead in the plug-on funnel, can form a lock. This lock can be overcome by vigorous turning; an overcoming by vertically acting forces, such as. B. when the ampoule falls, is not possible. Other options for securing transportation are e.g. B. bayonet catches or a tear-off tab that must be removed before screwing in. The opening aid according to the invention ensures a safe opening of the ampoule and a quick, complete and loss-free transfer of the ampoule contents into a volumetric flask or into a beaker. No further aids, which may be dangerous or impair the contents of the ampoule, are required to open the ampoule.
