Bez.χ Ready-to-use Ausqloaor that can be elnatechable in a container

The invention relates to a tubular spout that can be pierced into a container for dispensing liquids the container with a piercing tip which is arranged at the lower end of the tube and is provided with an opening, and a sealing sleeve arranged over the piercing tip;

Known tubular «spouts (CH-PS 412 608) have a frustoconical or pyramidal piercing point, Above which a screw thread is arranged, which is on its top is covered by a sealing ring. With such a design, after piercing the pack of the liquid container » Screw in the pourer until the sealing ring rests firmly on the top of the container. The most important However, the seal created on the top is horny lose already with a slight reverse rotation, provided that the seal is created by the thread itself, which, however, is hardly feasible in practice, since something like this is an ohread from a particular which material would presuppose · more advantageous are therefore pourers that can also be used without a · screwing movement

The object of the invention is to create a pourer, which is connected to the container in a solid and liquid-tight manner simply by piercing it and the one allows perfect drainage of the liquid without significant deflection of the liquid flow. According to the invention it is provided that the tube and the piercing tip formed by an inclined tube cut over the full height have a circular cross-section and the tube above the piercing tip has a widening upwards frustoconical gasket that bears the bottom ■ with an internally arranged annular bead engages in an annular groove of the pipe ·· and is located at the top on a shoulder of the pipe while leaving a gap between the pipe and the collar supported on the pipe. With this arrangement a hole is created in the container from the start of the piercing process, which has the same curvature diameter from the start the wall has, so that is not continuously expanded outward during the piercing and daa is then sealed by springing back or yielding the sealing sleeve in the direction of the pipe · Da This is the space between the pipe and the seal assembly steadily expanded from its lower edge upwards due to the conical design of the sealing sleeve on the one hand and the constant cross-section on the other hand, the strength of the poetry increases, the age the pourer stabbed into the container · It can prevent it from springing back or falling out evaluate, load the sealing sleeve on its outside

provided with several annular flexible sealing lips that are on top of each other and under the edge of the container Grip the opening when piercing, so that they prevent the spout from shifting backwards.

It has also been shown to be advantageous for the proper hold of the loosely attached sealing sleeve, if this is provided at the top with an outwardly facing annular flange, which is located on an annular shoulder of the pipe able to support. In addition, it is also useful here if the pipe itself consists of a hard plastic and the sealing sleeve made of a soft plastic. It can have an outside diameter in its lower area have, which corresponds to the diameter of the piercing tip, so that the seal is only created after the The lower edge section of the sealing sleeve is pushed through the puncture opening.

To cut a perfect circular hole in the container during the piercing process and also an unobstructed one To ensure proper outflow of the liquid, it was recognized as useful if the cutting angle of the pipe at the piercing tip has an »angle of about 30 ° to the pipe axis«

An embodiment of the invention is explained below with reference to a drawing. Xn of the drawing show ι

Figure 1 »An Auegießer in longitudinal section and Figure 2: a side view along the line II-II ·

The spout shown in FIG. 1 consists essentially of a tube I _1, the middle section 2 of which is provided with an annular groove 3 in its lower part. The pipe section 4 standing below the groove 3 is provided with an inclined bevel to form a passage opening 5 for the liquid, the inclination angle of which is about 30 ° to the pipe length "

The outer diameter of the lower pipe section 4 is slightly larger than that of the middle pipe section 2, so dad at fixed insert of the sealing sleeve on the middle pipe section no disadvantageous jump in diameter occurs.

The upper edge of the middle pipe section 2 is delimited by a shoulder 6, over which the pipe 1 is enlarged Diameter continues the upper edge of the tube l is closed by a removable cap 7

For sealing the spout in a container, there is one frustoconical sealing collar 8 is provided, the engages in the groove 3 with an inwardly extending annular bead 9 arranged at the bottom. The sealing collar 8 has a collar 10 at its upper end, with which “it is supported on the underside of the shoulder 6. On hers Outside between the bead 9 and the collar 10 carries dl

Sealing sleeve 8 several lying on top of each other · ring » Shaped sealing lips 11, dished upwards and downwards durchaubieg * n be able to.

Due to the truncated cone shape of the dicbtungeanchette 8 and the cylindrical shape of the central tohrabechette 2, there is a free space like the two parts, the size of which widens upwards. Within this area the sealing cuff 8 fails to move resiliently close to the inside ”so that when“ Sin ”pierce or“ several sighting lips 11 penetrate through the perforation, in order to provide resistance against falling out when the sealing cuff 8 springs back into the sealing position su can.
