BAD ORlGiMAL

already instead of the usual tubes made of metal, in which the substance is squeezed out by squeezing the tube, proposed devices in which a -Bag or a yielding product that distributes the ssu containing cartridge is inserted into a rigid case, which is designed so that the squeezing of the Product was done by twisting the resilient bag

The advantage of such facilities is in the possibility of one gradual, regular and complete squeezing of the product see below, with the cover at the same time being its original one Maintains appearance "

Despite these advantages, these have torsional distribution devices found no commercial dissemination, because the technical parts that brought the different solutions with them » could not be fixed.

One of these solutions is that each end has a flexible The bag is hung between two separate pools, the separation by a rigid, the container forming shell takes place. One of the flanges serves as a base and is rotatable, the other carries an outlet adjustment device, which is in communication with the interior of the bag.

During its use it suffices for that which serves as the ground To spin splash; by this movement the bag is twisted, whereby the product contained in it through the outlet Adjusting device containing the end is pressed o Here but a main problem arises for which solutions have not yet been found «You! Torsion actually leads to a reduction in the length of the bag, which, depending on the bag shape, can be up to 35 $ of the initial length. A complete and regular twisting of the bag without To achieve the risk of cracking, a separation distance must be left between the two fastening ends, which is not is equal to the length of the bag, but equal to what the bag takes up after being completely twisted,

So if you want the bag to twist as a whole without difficulty, then it is to be placed between the It is not stretched at both attachment points in this position only more than unlikely to reckon with a regular twist, at the same time it is impossible to determine the exact Provide a place where the twisting begins of the product wants to necessarily begin at the end opposite the outlet opening will.

In order to remedy these drawbacks, it is known to provide one of the flanges _t to which the ends of the bag are fastened so that it slides inside the rigid envelope or that one of the bag ends is fastened by means of a spring in order to shorten the bag by maintaining sufficient tension for regular rotation. This procedure only makes the implementation of such distributors even more difficult, which obviously means a commercial loss: higher production price, difficult attachment of the bag, inability to replace, lack of security against possible damage »

Other distributors are designed in such a way that dttordleren is avoided air will get inside the bag.

All these pre-prepared solutions use βin «a manufactured, bags filled one after the other, the production of which is therefore slow and the price of which is high.

According to the invention, these halves are to be remedied at the same time be, namely

every precautionary measure for shortening and prevention a provision no longer applies; preferably the entry of air into the bag is prevented;
