Pouring spout with closure on canisters

description

Spouts are known which are provided with a thread and for emptying can be screwed onto a threaded connector from canisters of any shape. As a rule, such pouring spouts are made outside of the canister held by a strap or by being clamped in the handle. However, this has the disadvantage that the pouring spout in the event of vibrations and the like. can get lost

Pourers are also known which are sunk into the inner part of a canister and which are pulled out on the inner edge of the pouring spout be held clamped. Such pourers are usually from the made of the same rigid elastic material as the canister itself.

In practical use, however, such canister designs have the disadvantage that with the often difficult introduction of the pouring spout into the tank neck of the vehicle due to the rigid design at the sealing point or inside Leakages occur in the thread due to the material distortion, which can lead to unpleasant consequences, for example with gasoline as a filling material.

The design described below has the disadvantages described here largely switched off. The pouring spout (L), preferably from one made of flexible thermoplastic material, has a number of bellows-like constrictions (2) in the front half, which the front half

Claims (2)

Make the end of the already somewhat flexible pouring spout even more elastic. The pouring spout ß) is widened conically at one end (3) and clamps positively into a threaded ring (4) which has an internal thread (5) at one end that fits onto the threaded connector of the canister and at the upper end (6) also has an internal thread into which the cover (8) engages with a corresponding seal. The length of the pouring spout is so dimensioned that it extends to the inner bottom of the canister. So that there is no air vacuum when pouring out and consequently the pouring out of the liquid is hindered, the pouring spout (L) has a nose-shaped protuberance inward (7) at the upper end below the conical expansion, which is closed in the pouring direction so that no liquid is poured in Pouring can escape, but air does enter. This nose-shaped protuberance is injection-molded or blow-molded from one piece. Protection claims: 1. Spout (1) on canisters using a calibrated thermoplastic, preferably polyethylene, characterized in that it is conically widened at one end (3) and is positively received by a threaded ring (4) which is held by means of two internally threaded parts (5/6) can be screwed onto the canister in such a way that in one case the pouring spout is directed inwards and in the other case outwards and is provided with a number of bellows-like constrictions (2) in the area towards the mouth. 2. Spout on canisters using a flexible thermoplastic material, preferably polyethylene, according to An Spruch 1., characterized in that in the insertion area below the conical Expansion (3) inwardly in one piece from the same material and a protruding one Nose (7) is pronounced, which has an opening (10) for air to escape towards the direction of the mouth 680C676
