Description

Die Erfindung bezieht sieh auf Behälter für Flüssiggas, wie Propan und Butan, und bezweckt, in dezgleichen Behältern, wenn sie gänzlich mit Flüssigkeit gefüllt sind, gefährliche Druckerhöhungen infolge Wärmedehnung zu verhindern, wodurch das Füllen solcher Behälter beträchtlich erleichtert-Wird. Dies ist besonders wichtig bei den Flüssiggasflaschen mit geringerem Inhalt, z. B. 400-. Dergleichen Kleinstflaschen sind besonders beliebt bei Arbeiten auf Dächern zum Abbrennen von Anstrichen usw., da sie leicht mitzuführen und zu handhaben sind. Das Nachfüllen dieser Flaschen stieß bislang auf Schwierigkeiten, da sich die Füllstationen häufig in größerer Entfernung vom Sitz des Handwerksbetriebes befinden und das Selbstfüllen wegen der Gefahr der Überfüllung* als zu gefährlich abgelehnt werden muß. Wenn nämlich beim Selbstfüllen die Flasche völlig mit Flüssiggas in flüssiger Phase gefüllt wird, können bei Erwärmung, z. B. durch Sonnenstrahlung, Drücke auftreten, welche die Flasche sprengen, da kein Sicherheitsraum in der Flasche vorhanden ist.The invention relates to containers for liquefied gas such as propane and butane, and intended in decal containers when they are completely filled with liquid are filled to prevent dangerous pressure increases as a result of thermal expansion, whereby the filling of such containers is considerably facilitated. This is especially important in the case of liquefied gas bottles with a smaller content, e.g. B. 400-. Such small bottles are particularly popular when working on roofs to burn off paint, etc., because they are easy to carry and to handle. Refilling these bottles has so far encountered difficulties, as the filling stations are often larger Distance from the seat of the craft business and self-filling because of the Risk of overcrowding * must be rejected as too dangerous. If namely with Self-filling the bottle is completely filled with LPG in the liquid phase, can when heated, e.g. B. by solar radiation, pressures occur which the Blow up the bottle as there is no safety room in the bottle.

Die Erfindung besteht darin, däß der Flüssiggasbehälter mit einem elastischen Glied versehen ist, welches bei einem Steigen des im Innern des Behälters herrschenden Druckes eine solche Volumenvergrößerung des Innenvolumens des Behälters herbeiführt, daß bei Temperatursteigerungen auftretende Wärmeausdehnungen der Flüssigkeit aufgenommen werden, ohne daß der Druck in der Flasche ein zulässiges Maß übersteigt. Ein gefahrloses Selbstfüllen wird also ermöglicht.The invention consists in that the liquid gas container with a elastic member is provided, which when the inside of the container rises prevailing pressure such an increase in volume of the internal volume of the container causes thermal expansion of the liquid when the temperature rises be absorbed without the pressure in the bottle exceeding a permissible level. Safe self-filling is therefore made possible.

Die Erfindung wird im folgenden an Hand schematischer Zeichnungen an einigen Ausführungsbeispielen beschrieben. Es zeigt Fig. i einen Flüssiggasbehälter, in dessen Innerem ein gasgefüllter Faltenbalg vorgesehen ist, Fig.2 einen Flüssiggasbehälter, in dessen Innerem eine gasgefüllteMembrandosevorgesehen ist, Fig.3 einen Flüssiggasbehälter, in dessen Innerem ein aus Schaumgummi hergestellter Körper vorgesehen ist, Fig.4 einen Flüssiggasbe'hälter, in dessen Innerem ein gasgefüllter aus Gummi hergestellter Hohlkörper vorgesehen ist.The invention is illustrated below with reference to schematic drawings described in some exemplary embodiments. It shows Fig. I a liquid gas container, inside of which a gas-filled bellows is provided, Fig. 2 a liquid gas container, inside of which a gas-filled membrane can is provided, Fig. 3 a liquid gas container, in the interior of which a body made of foam rubber is provided, Fig.4 a liquid gas container, inside of which a gas-filled one made of rubber Hollow body is provided.

In Fig. i ist eine Fliissiggaskleinstflasehe i dargestellt, welche nach Anordnung eines gasgefüllten, durch eine Feder gespreizten Faltenbalgs :2 zum Selbstfüllen geeignet ist. Der Balg kann an der Flasche i befestigt sein, doch ist dies keine Notwendigkeit. Wenn er nicht dauernd an der Flasche befestigt ist, kann der Balg mit Nasen 3 versehen sein, welche einem Abdichten der Öffnung 4 bei voller Flasche vorbeugen. Ein auf dem Flüssiggas schwimmender Balg dagegen verringert die Verdunstungsoberfläche in der Gasflasche, so @daß die Gaslieferung in diesem Falle ungünstig beein:flußt wird.In Fig. I a small liquid gas bottle is shown which according to the arrangement of a gas-filled bellows expanded by a spring: 2 for Self-filling is suitable. The bellows can be attached to the bottle i, but is no need to do this. If it is not permanently attached to the bottle, it can the bellows may be provided with lugs 3, which seal the opening 4 when full Prevent the bottle. On the other hand, a bellows floating on the liquid gas reduces this Evaporation surface in the gas bottle, so @ that the gas delivery in this case is unfavorably influenced.

Die Gasflasche 5 in Fig. 2 enthält eine gasgefüllte Membrandose 6.The gas bottle 5 in FIG. 2 contains a gas-filled membrane can 6.

In Gasflasche 7 (Fig. 3) ist ein aus- Schaumgummihergestellter Körper 8 vorgesehen, der durch im Innern der Gasflasche angeordnete Nasen g daran gehindert wird, auf dem Flüssiggas zu schwimmen.In gas bottle 7 (Fig. 3) is a body made of foam rubber 8 is provided, which is prevented from doing so by lugs g arranged inside the gas cylinder is going to swim on the liquefied petroleum gas.

Fig. 4 zeigt eine Anordnung, in der ras gasgefüllte, mit elastischen Wänden versehene Glied durch einen aus Gummi 'hergestellten Hohlkörper dargestellt wird. Dieser Körper- kann mehrere Formen haben, von denen ein langgedehnter Zylinder io mit kreisförmigen oder elliptischem Querschnitt die geeignetste ist.Fig. 4 shows an arrangement in which ras gas-filled, with elastic Walls provided member represented by a hollow body made of rubber ' will. This body can have several shapes, one of which is an elongated cylinder io with a circular or elliptical cross-section is the most suitable.

Für kleine Flaschen mit 22ä atü Prüfdruck genügt ein elastisches Glied, das so klein ist, daß es durch den Flaschenhals eingeführt werden kann.An elastic link is sufficient for small bottles with a test pressure of 22 °. that is so small that it can be inserted through the neck of the bottle.
