Since the beginning of the century, containers were made from cardboard made impermeable , attempts have been made to simplify production by using a previously coated material, as opposed to the original method, in which the container is first made and then impermeable is thought, be it by immersing an appropriate permeable or hardening liquid ofier durela spraying the liquid onto the surfaces to be protected.

However, while the original method, which can be referred to as "Pinieh spread", allows practically perfect tightness, it has quickly been found that the method of "prior spreading" or using a composite material does not lead to equally good results. In these processes, all the free Εαηΐ-3 of the layer is not protected; The liquid kits often clash very quickly into the total © Warn ', a sum that is "iohi?; ground and, if necessary, is filled to remove the liquids"

Other special experiences have already been suggested to avoid this disadvantage. Sq one applies a coat of paint with a brush under bridges on open vexable rope or folds back the edge of the flanks or impermeable segments in such a way that Sick forms a hand with an impermeable "layer". "Each of these processes" brings an additional one Work step with itself, either ssu beginning (folding the edge) or at the end (brushing with the brush). What they have in common is that after cutting the paper into the sweeping forja to produce the desired container, this measure is inserted and represents an additional work step »

In the mechanical design, the latter is a source of difficulties and can give rise to operational incidents "which reduce the actual production yield"

If this operation is carried out by hand, ". It is extremely cumbersome, also the 6-lightness is missing on the project,

. "The procedure in which the land is transshipped is calling in addition, the formation of a considerable excess thickness

The cut formed according to the fire makes it possible it, while avoiding all of the laughable parts described, containers of different shapes, including cylindrical ones or to be able to produce a truncated cone shape »

For this purpose, the innovation a ^ 8 is based on a cut made of Yerbundioater ial "consisting of an impermeable layer, K ₀ B * a polyethylene film and. a carrier layer » ζ » Β. is "wherein at least one band portion of the blank or its carrier layer" which koraaat with DEAA content of the finished container or tube into contact, also covered from thin cardboard impermeable, and features ± m essentially by a new EaumforiB for this cutting to the extent that the Covering the relevant hand part of the blank or «whose!

Another feature of the innovation is that that the relevant tape part of the blank or whose carrier layer is chamfered

Another feature of the kennseich.net firing system is that that the extension of the impermeable Abdeokschicht of the cut over the handle part of the cut baw »whose working class bsw. about the fringing of this Protruding part of the band "

Another feature of the innovation is that that the board of directors of the extension of the "opaque" The blanket of the blank looks like it is impermeable Cover layer opposite surface of the carrier layer of the Z-uchnitt folded over and with this Surface is firmly connected.

Another feature of the control is that the board of the extension of the ■ impermeable cover layer of the blank remains free and unattached "

Another characteristic of hiring can be found in that dis the undux'leaguer cover layer of the Cut the opposite surface of the slant

also has an impermeable cover.

For the production of a blank according to Figo 1e is aunächst according to FIG. 1a of the Eandteil 1 a supporting film 2, for example made of thin cardboard, obliquely afogefast by decreased at 3 material, whereby an inclined surface 4 results.

In a long work step (Pig * Ib), the carrier film 2 is covered on one of its sides with a film 5 of an impermeable material, e.g. ₁₆ , a 3? Ethylene film _? covered, which rests on the inclined surface 4 and protrudes at 7 over the thinned edge part »

According to Fig. ₄ 1c, the overhanging end 7 of the filament 5 is due to its own weight or by a sweat-like guide ₉ ^ ₀ B ₀ through a little or under the influence of the lines 8 corresponding downward air streams downwards

G-einäß 1d propose horizontal air jets 9 $ which are blown to the inside of the film 2, the projecting end 7 to _t which then fig »according Ie is mounted under the film 2 by this film, the overall öüsmer

made edge part 10 of the latter complete in this way is wrapped up by the Sciratascliicht 5 "

FIG. 2 shows a tight connection which can be formed with a blank produced in this way. Here, the band portion is passed the 'ürägerfolie 2 against the inner wall 5 made impermeable 10 and the folded cable 7' of the band portion envelops _t to this wall welded or glued. In this way, the material strip is protected against any infiltration of iron liquid that is in the can.Due to the thinning of the edge part, the change in the thickness of the wall in the connecting area takes place gradually, which makes it easier to insert the bottom of the container and ensured a better tightness of the floor

The chamfering of the part on the Surface of the carrier sees carried out »which the un ·» permeable film should take up * But you can also this abfasuag on the other surface or, if applicable, on ibei & eH surfaces of the carrier foil make β
