Abstract

The spout has a screw-in and off thread (2) plus pierce tip (1), channel (4) and separate closure cap (5) as well as a seal (3) and packing (6). The spout material and design are optional and the cap (5), if used should be integral. The thread can be replaced by a snapper or plug- or latch-on device, and the tip can be replaced by a cut-in edge. Various types of adaptor (7) are used to regulate and meter the flow volume and the seal (3) alone can be sufficient thus without the packing ring (6). The spout has its own vent hole. In use, the spout is gripped above the seal so the downward tip can pierce the can etc. leaving a small hole for the spout thread to engage so the packing ring seats onto the top of the can etc. as seal. The cap (5) closes off the spout as required, and the spout is simply screwed out of the emptied can etc. for reuse.

Description

Verpackungen und Behälter, in denen eine fließfähige Substanz oder Flüssigkeit enthalten ist, z. B. Verpackungen für Milch, Säfte, Salz usw., haben üblicherweise einen fest angebrachten oder keinen Ausgießer.Packaging and containers in which a flowable substance or liquid is contained, e.g. B. Packaging for milk, juices, salt, etc., usually has one firmly attached or none Spout.

Ist kein Ausgießer vorhanden, muß die Verpackung oder der Behälter aufgeschnitten, aufgerissen, eingedrückt etc. werden.If there is no spout, the packaging or container must be cut open, torn open, be pushed in etc.

Der fest angebrachte Ausgießer an einigen Verpackungen und Behältern ist nicht wiederverwendbar.The fixed spout on some packaging and containers is not reusable.

Die Erfindung betrifft einen verschließfähigen und wiederverwendbaren Ausgießer, der bei Bedarf in Verpackungen und Behälter nachträglich eingesetzt wird. Er dient zum Ausgießen einer fließfähigen Substanz oder einer Flüssigkeit aus einer Verpackung bzw. einem Behälter. Gleichzeitig kann er ein Austreten der fließfähigen Substanz/Flüssigkeit mittels einer Verschlußkappe verhindern. Es besteht die Möglichkeit diesen Ausgießer aus verschiedenen Materialen herzustellen: Metall, Keramik, Glas, Holz, Kunststoff u.ä.The invention relates to a closable and reusable pourer, which, if necessary Packaging and containers are used later. It serves to pour a flowable Substance or liquid from a package or container. At the same time, he can Prevent the flowable substance / liquid from escaping with a cap. There is the Possibility to produce this spout from different materials: metal, ceramic, glass, wood, Plastic, etc.

Der Ausgießer kann durch Einstechen oder Einschneiden und anschließenden Rasten, Schnappen, Stecken oder Gewinde in die Verpackung bzw. in den Behälter eingesetzt werden. Die dadurch entstandene Öffnung kann über einen Dichtungsring abgedichtet werden.The spout can be inserted or pierced and then snapped, snapped, Insert or thread into the packaging or into the container. The result created opening can be sealed with a sealing ring.

Die Austrittsmenge der fließfähigen Substanz/Flüssigkeit ist durch verschiedene Bau- und Formgrößen oder mittels Adapterstücke regulier- und dosierbar.The discharge quantity of the flowable substance / liquid is due to different sizes and shapes or adjustable and dosed using adapter pieces.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß ohne zusätzliches Werkzeug, wie z. B. Schere, Messer, usw. ein regulier- oder dosierbares Ausgießen durch das Einsetzen des Ausgießers ermöglicht wird.The advantages achieved by the invention are in particular that without additional tools, such as B. scissors, knives, etc. a controllable or metered pouring by inserting the Pourer is made possible.

Gegenüber vielen handelsüblichen Verpackungen und Behältern ist es möglich mit dem nachträglichen Einbau des Ausgießers mit Verschlußkappe die Verpackung/Behälter wieder zu verschließen. Ein Schütteln der fließfähigen Substanz/Flüssigkeit (z. B. bei Säften) in der Verpackung/Behälter ist über den verschließbaren Ausgießer gegeben.Compared to many commercially available packaging and containers, it is possible with the subsequent one Installation of the spout with a cap to close the packaging / container again. A Shake the flowable substance / liquid (e.g. in the case of juices) in the packaging / container closable spout given.

Ferner ist der Ausgießer ist durch leichten Ein- und Ausbau wiederverwendbar. Furthermore, the spout is reusable due to easy installation and removal.  

Figurencharacters

Die Abbildungen Fig. 1 und Fig. 2 zeigen die wichtigsten Teile und Funktionen des Ausgießers. Sie zeigen den prinzipiellen Aufbau in schematischer Weise. Dabei stellt Fig. 2 nur eines von mehreren Ausführungs- und Verwendungsmöglichkeiten dar:The illustrations Fig. 1 and Fig. 2 show the main parts and functions of the spout. They show the basic structure in a schematic way. In this case, Figure 2 illustrates only one of several embodiments and uses.:

Fig. 2a Einstechen des Ausgießers; FIG. 2a insertion of the spout;

Fig. 2b Ein- und Ausschrauben des Ausgießers; Fig. 2b screwing and unscrewing the spout;

Fig. 2c Abdichten der entstandenen Öffnung; Fig. 2c sealing the resulting opening;

Fig. 2d Ausgießen der fließfähigen Substanz oder Flüssigkeit. Fig. 2d pouring the flowable substance or liquid.

Der Ausgießer nach Fig. 1 ist oberhalb des Dichtungsabsatzes (3) anzufassen, so daß die Einstechspitze (1) senkrecht nach unten zeigt. Die Einstechspitze mit einem leichten Druck nach Fig. 2a von oben in die Verpackung oder den Behälter einstechen, wodurch ein kleines Loch entsteht. In dieses Loch wird das Ein- und Ausschraubgewinde (2) durch Drehen am Ausgießer gemäß Fig. 2b hineingeschraubt bis sich, wie Fig. 2c zeigt, der Dichtungsabsatz (3) mit dem Dichtungsring (6) auf die Verpackungs- /Behälteroberfläche legt und abdichtet. Nach Fig. 2d kann jetzt die fließfähige Substanz/Flüssigkeit aus dem Durchflußkanal (4) fließen. Bei Aufdrücken der Verschlußkappe (5) von oben auf den Durchflußkanal wird der Ausgießer verschlossen und es kann keine fließfähige Substanz/Flüssigkeit austreten. Ist der Inhalt geleert, wird der Ausgießer durch Ausschrauben aus der Verpackung/Behälter wieder entfernt und ist wiederverwendbar.1 is to be handled above the sealing shoulder ( 3 ), so that the piercing tip ( 1 ) points vertically downwards. Use a light pressure as shown in Fig. 2a to insert the puncture tip into the packaging or container from above, creating a small hole. The screw-in and screw-out thread ( 2 ) is screwed into this hole by turning the spout according to FIG. 2b until, as shown in FIG. 2c, the sealing shoulder ( 3 ) with the sealing ring ( 6 ) lies on the packaging / container surface and seals . According to Fig. 2d, the flowable substance / liquid can now flow from the flow channel ( 4 ). When the cap ( 5 ) is pressed onto the flow channel from above, the spout is closed and no flowable substance / liquid can escape. If the contents are empty, the spout is removed from the packaging / container by unscrewing and can be reused.
