Description

Aus zwei Metallschalen zusammengesetzte Wärmflasche. Bei den bisher bekannten Wärmflaschen ist die Luft- und wasserdichte Verbindung des schalealaxhigen Boden- und Deckeltdurch Löten oder im Tauchverfahren durch ein Bindemittel hergestellt. Selche Gefäße werden bei rauher Behandlung oder infolge des bei Abkühlung des Inhaltes im Innern ent stehenden Unterdruckes durch Aufplatzen dex Lötnaht leicht undicht. Die Herstellung der Lötnaht ist außerdem teuer.Hot water bottle composed of two metal bowls. With the so far well-known hot water bottles is the airtight and watertight connection of the shell-axed Bottom and lid made by soldering or by a dipping process with a binding agent. Such vessels are damaged by rough handling or as a result of the cooling of the contents The negative pressure created inside by the bursting of the solder seam is slightly leaking. The production of the solder seam is also expensive.

Durch die vorliegende Erfindung sollen die geschilderten Nachteile beseitigt werden. Das Wesen der Erfindung liegt darin, daß die Falzränder der Schalen der Wärmflasche, ungefähr in, der Äquatorehene aufeinanderliegend; gleichsinnig zweimal umgebogen und unter Weglassung einer Lot- oder Schweißverbindung derart zusammengepreßt sind, .daß die Kante des äußeren Flanschrandes, die des inneren überragend, um die letztere herumgebogen ist. Der Erfindungsgegenstand ist auf der Zeichnung beispielsweise veranschaulicht; es stellt dar: Abbt i eine Wärmflasche, teils in Ansicht, teils im Schnitt, Abb. z einen Schnitt durch die Verbindungsstelle zweier Schalenteile des Gegenstandes nach Abb. i in vergrößertem Maßstabe.The disadvantages outlined are intended by the present invention be eliminated. The essence of the invention is that the folded edges of the shells the hot water bottle, roughly in, the equatorial one on top of the other; bent twice in the same direction and omitting a soldered or welded connection are compressed in such a way that the edge of the outer flange edge, that of the inner towering, around which the latter is bent. The subject of the invention is on the Drawing illustrates example; it represents: Abbot i a hot water bottle, partly in view, partly in section, Fig. z a section through the connection point two shell parts of the object according to Fig. i on an enlarged scale.

Die auf der Zeichnung veranschaulichte Wärmflasche besteht aus einem schalenartigen Bodenteile, einem ebensolchen Deckelteil b und .einem Füllansatz der einer Füllschraube c; letztere ist durch. Niete h mit dem Deckelteil b verbunden.The hot water bottle illustrated in the drawing consists of one shell-like bottom parts, a cover part b and .einem filling approach that of a filling screw c; the latter is through. Rivet h connected to cover part b.

Erfindungsgemäß sind die Teile der Wärmflasche in der Weise miteinander vereinigt, daß Falzränder d, e an den schalenartigen Metallteilen a und b vorgesehen und diese Falzränder, ungefähr in der Äquatorebene der Wärmflasche aufeinanderlegend,. gleichsinnig zweimal umgebogen und unter Weglassung einer Lot- oder Schweißverbindung derart zusammengeprzßt sind, daß die Kante des äußeren Flanschrandes f, diejenige des inneren Flanschrandes g überragend, um die letztere herumgebogen ist. Auf diese Weise wird eine lullt und wasserdichte Verbindung der beiden Schalen der Wärmflasche erzielt, und es wird gleichzeitig am Außenumfang der Wärmflasche ein kräftiger Wulst gebildet, welcher wesentlich zur Versteifung dier Wände der Wärm$asiche beiträgt.According to the invention, the parts of the hot water bottle are combined with one another in such a way that folded edges d, e are provided on the shell-like metal parts a and b and these folded edges lie on top of one another approximately in the equatorial plane of the hot water bottle. are bent twice in the same direction and are pressed together with the omission of a soldered or welded connection in such a way that the edge of the outer flange edge f, protruding that of the inner flange edge g, is bent around the latter. In this way, a lulled and watertight connection of the two shells of the hot water bottle is achieved, and at the same time a strong bead is formed on the outer circumference of the hot water bottle, which significantly contributes to the stiffening of the walls of the hot water bottle.

Selbstverständlich ist es auch ohne weiteres möglich., die Falzränder d, e anstatt nach dem Bodenteil nach dem Deckelteil umzuhördeln.Of course, it is also easily possible to flap the folded edges d, e after the cover part instead of the base part.
