Abstract

Simultaneous delivery system for two different pastes or mixtures of similar consistency stored in a container such as metal tube fitted with an outlet head as in 2053109.3. The outlet head is connected to the neck of the container by a one piece plastic unit affixed to the tube's neck and covering both it's inner and outer wall. A thread is fitted to the outer circumference of the plastics unit, which is attached to the neck of the tube by wedge ribs fitted to it's outside in a longitudinal direction. Preferably the ribs are at least partly provided with notches.

Device for the simultaneous dispensing of two different pastes or compositions similar consistency from a container

The invention relates to an improvement on the patent

No (patent application P? O 53 1o9.3) protected

Device for the simultaneous dispensing of two different pastes or compositions of similar consistency, which are accommodated next to one another in a container, in particular a metal tube, and are dispensed from the container with the formation of a common strand. This apparatus is characterized in _t that the container has a mouth head having a main channel in the form of a beidaeitig open pipe which extends into the container, and lying in the main channel sub-channel of the surrounding through the wall of the open pipe with the pipe space is connected, has, the smaller part of the paste to be dispensed through the secondary channel in the space surrounding the tube and the larger part of the paste to be dispensed through the main channel being accommodated in the pest of the container.

According to a preferred embodiment of this device, the mouth head is made of plastic, as it fits into the container existing use trained «It has now been found that such a device can be used the patent no. .... ... (patent application P 2o 53 1o9.3) in the form of an insert that fits into the container is particularly advantageous can perform if this insert is used together with a known per se placed on the container neck, One-piece plastic body covering its inner wall and outer wall, preferably a thread on its outer circumference is trained, executes.

Such plastic bodies, also as connecting pieces or threaded sleeves known, often also provided with the common name "threaded nipple", are for example in the German Utility models No. 1 889 369 and 1 923 352 described. They are for example in the way on the container neck attached that tooth-like projections are attached to this, which penetrate into the outer cylinder of the plastic body when it is applied. The container neck can be used to attach the Plastic body and to secure against possible rotation the same can also be provided with longitudinal or axial wedge ribs; the execution is particularly useful of diametrically opposed longitudinal wedge ribs. Instead of this, grooves or grooves can also be used for fastening be used. Longitudinal wedge ribs can also partially act with an additional one in the axial direction Securing in the form of one or more notches, which are produced by rolling over the V-ribs radially be, so that the strength of the closure between the plastic body and tube neck is improved.

In principle, to apply the combination according to the invention made of plastic sleeve and insert on the container, any of the described,. Suitable methods, such as in the German Auslegeschrift No. 1 93o 995 and the German Utility models No. 1 889 369 and No. 1 923 352 are shown, apply.

The combination of those designed as an insert that fits into the container The device according to the invention with the plastic sleeve of known type has the particular advantage that in the Manufacture of this part with the associated screw cap for closing the container can be pre-assembled, whereby a significant rationalization in the »production line achieved will.

The thus prefabricated closure unit from the device according to the invention and screw cap is now pressed onto the tube neck by means of a tool that moves in a straight line, whereby the otherwise There is no need for an opening process in the machine.

In addition, containers provided with this insert, in particular metal tubes, have a more aesthetic appearance; the use according to the invention also serves as Corrosion protection for the inside of the tube neck. The embodiment laid down in the drawing shows a longitudinal section through a filled, with the invention Device equipped metal tube (1) with screwed-on cap (2).

The tube neck (3) is surrounded on the inside and outside by a plastic body (4) which has a thread on its outer surface for attaching the screw cap (2). The plastic body (4), which is attached to the tube neck by means of the projections (5), merges into a tube (4 ¹ ) open on both sides in the interior of the tube. In the middle of this insert a secondary channel (6) is attached, which is connected through the wall of the pipe (4 ¹ ) through round or rectangular, for example square holes (7) with the space surrounding the pipe (0), where the smaller one Part of the paste filled in the tube is located.

With external pressure on the filled tube, this smaller part of the paste is through the secondary channel (6) with the main part of the Paste, which is housed in the rest of the container (9) and flows through the main channel (1o), in one when it leaves the tube shared strand.

The areas of application of with the device according to the invention equipped containers, such as metal tubes, are set out in detail in the main patent and apply mutatis mutandis here as well.
