Description

"Let, container or the like provided with a spigot, ordered from metal, plastic or the like .. ¹¹

The subject of the innovation "relates to a (s) with a piercing socket, consisting of metal, plastic or the like., provided (r) passport, container or the like ..

There are piercing sockets for passports, containers or the like. in the various types of execution "known. The prior art piercing bushings can be made from Plastic, metal or a similar material.

In the passport industry, particularly in the brewing industry, it is now common knowledge that the bunghole of the various To provide passports with a piercing socket. The end of these piercing bushes is done by a plug. This plug is mainly made of cork or similar. Material made. When the passport is pierced, the The plug introduced into the tapping socket was pushed into the passport under the action of a blow and, at the same time, the The leased line union screwed into the bunghole.

The disadvantage of these known plug is that with different bore holes within the A suitable cork stopper for each tapping socket

must be selected. Differences between the bore and the plug result from small dimensional unevenness. Furthermore, the introduction of the cork plugs is to be regarded as a disadvantage, since this introduction with considerable additional hours of work is associated, namely in that the cork are heated prior to introduction must, so that it contracts. After the insertion, the cork stopper cools down again and expands look so that the bore of the tapping socket is sealed.

Another disadvantage is that the use of cork reduces the manufacturing costs of these sealing plugs become significantly more expensive. Ultimately, it is still to be seen as a disadvantage that the inserted cork plug in one Suddenly occurring overpressure in the barrel, container or the like easily flies out.

The object of the innovation has now set itself the task of revealing an improvement in this area, whereby the disadvantages indicated are avoided. To this end, the subject of innovation is through it characterized in that the piercing bushing is a retractable plastic or the like. existing cork-like design Has sealing plug.

furthermore, the sealing plug has one at one end

Stopper head with "broad collar, and on his Circumferential lips arranged at a distance from one another on the lateral surface.

The stopper head and the circumferential lips of the stopper are barbed-like and flexible, so that when the stopper is pushed into the tapping socket, the stopper head and the lips are pressed together on the liaison of the tapping socket.

Furthermore, the subject of the innovation is characterized in that the plug head is circumferential on the inside Elevations, in the form of sealing cords or the like., having.

However, the protection should not only be limited to the features disclosed in the claims, but rather Protection is also claimed for those features that add to the description in conjunction with the drawings can be found. These are primarily equivalent funds.

Several embodiments of the subject of the innovation are shown in the drawing, it show:

lig. 2 the Ins ti ehTDUcla.se according to Pig. 1 with fully introduced Sealing plug,

lig. 3 another embodiment of the piercing "socket with Yersehl plug pushed in from below,

! Fig. 4 the closure plug according to the innovation in enlargement.

According to the lig. 1 to 3, the tapping bush is denoted by 1. The tapping socket 1 can be made of metal, plastic or the like. Material. In hole 1 'of the Pass 5 introduced tapping socket 1, the sealing plug 2 is inserted from above, (see Fig. 1) The sealing plug 2 has circumferential lips 4 and a plug head 3 provided with a wide collar 3 '(see FIG Pig. 4 ') · The Yerschlußstopfen 2 is made of plastic or the like. Material formed, wherein the plug head 3 with its collar 3 'and the surrounding lips 4 held flexible are.

When inserting into the bore 1 ^{f of} the tapping socket 1, the stopper head 3 and the circumferential flexible lips 4 lie close to the wall of the bore 1 '. After the plug 2 has been completely ^{inserted into the bore 1 l} , the plug head 3 with collar 3 ^f expands back into its Έοτ- mallage. In the inserted position of the sealing plug 2, the flexible lips 4 cause a threefold seal.

- 5th

In the interior of the stopper head 3 there are circumferential elevations in the form of sealing cords 3 ^! 'arranged. By means of these incorporated sealing ^{cords 3! T} , the inner collar 3 'of the plug head 3 nestles closely against the surroundings of the bore 1'. In this way, any unevenness that may exist is fully compensated and a secure seal to the outside is guaranteed.

The Yersehlußstopfen 2 can also for so-called. Siphon tap sockets Find use. In contrast to the generally used drawing bushes 1, the Yersehlußstopfen is used here 2 introduced from below (see Mg. 3). Here, too, the sealing lips 4 and the circumferential lips 3 cause a proper one Seal.

The advantage of the subject of the innovation over the familiar is that once through the training the sealing plug a secure seal - even with strong pressure - is guaranteed and on the other hand in that the use of plastic for the production of the stopper is a significant reduction in the Manufacturing cost is achieved.
