The in Eig. The container lo illustrated in FIG. 1 can be produced in an economical and convenient manner by a piston-assisted differential pressure method for polishing deformation, which will be described later. The turning strength of the container lo has a good uniformity . Advantageously, the container is made from a thermoplastic starting film, such as polyatyrene or the like. The wall star of the container in the finished, deformed state was said to be very thin, so that its use remains economical even if it is thrown out after use approx. " Di 9 vo XLIE g End a present invention is made in the loading Zusahmlenhang with the Behälterverfoimung. The method and the device used are, however, often more versatile. The description of the manufacture of a container is therefore only to be regarded as an example. The container lo has a bottom wall 12, which can have any suitable design and any diameter. The bottom wall ends at 14, where it converges with the side wall 16 , which extends upwards and outwards from there. Advantageously, the side wall 16 is smooth over most of its part, so that it is better for receiving printing or the like, be it for identifying the various products on the outer surface, or for advertising purposes. the various food producers and other users of the containers, suitable In the upper area of the side wall 16 there is an area 18 running radially outwards and upwards, which ends at 20 and forms an undercut shoulder. The numbered with 22 'wall portion advantageously extends upwardly and inwardly with a small l, Fini, el, so that where the region 22 zusaiii of about 3- 60 in lUchtungzur Beliälteracnse with dan region 26; lonlc-. - * uft an inner shoulder 24 b is formed. The area 2b advantageously extends a short distance approximately radially outward and converges with the areas 28 and 3o, whereby an Ouitz surface for a lid is created so that the contents of the container is closed after filling. The area of the side wall numbered with 32 runs in a curved shape towards the numeral, sen and above and ends in a ralz 34, which will be described in more detail.

The containers lo can be eighthed into one another, with part of the wall area 18 resting on the inner shoulder 24 of the adjacent container. It should be noted, the axial height of the areas 26,28 and daso 3o, as well as the axial height of the Biareiches 34 is smaller than the stack height, which corresponds to the axial fleas wall region of the 22nd

The T'alz 34 has an outer, undercut surface 33 see lPig. 1.1) an approximately vertically extending, radially outer surface 35 and an upper surface 37, which runs approximately parallel to the surface 33 . It should be noted in particular that the thicknesses where the areas 33, 35 and 37 meet are fairly well defined, which creates a good formation for the closure of a dropping cover9 uelcher around on the surface 33 engages and an easy handling by machines, such as filling and lid jigs is eimdgicht. Other characteristics of the lPal in% de standing - es 34 consist in the fact that the 2-pan # s are broken down during production by a half-hold and the printing forme process used. Thus, the Palz 34 has an extraordinarily good resistance to point-like foaming and in addition, it tends at punktartiger.Verfoimiung compared to known in he Wei se g ef o = t s in RILnde or 'Case zen far less for REI ss s. The reduction in tension in the Palz 34 is of considerable importance, for example, in the case of dairy products which are usually kept in refrigerated display cases in shops. Most thermoplastic materials have a greater tendency to tear along tension lines at lower temperatures, and this fact poses a particular problem with dairy products and the like. which, for example, previously in containers, viie in lPig. 1 shown have been packed. The ralz 34 in addition to the Verfoimungswi (toddlers - t * -, and to a considerable AV of the upper end f reien estigung of the container and thus contributes to the inside contained in foods to prevention of damage or leakage.

During the manufacture of the container 10, it is preferred that a pre-erased oil 36 is placed between an upper mold 38 and an opposite, lower mold 4o, preferably with the aid of a not shown front-end device the 'two Foriuhillftexi using geeignet'er by Pf, indicated devices 42-44 parts relative to each other are sawn wegbar. Although the present invention explained with reference to eim r Zirfachform with a corresponding male mold W ird, become in Wi iiili chkeit Vi olt & oh: EO ition with ents Imhenden Pagiriz'oll, vorsolohliAgen Urga vorgezor.Oft .. e # U0 Wert.Zutwaschine, wuläh4 ggt even e% do & the present invention is suitable $ dead, t * gives * instructions. The upper l'orn 38 consists essentially of an upper one in yrig. Plate 46, shown schematically in FIG. 2, with a central opening 48 which is connected to a compressed air source 54 via a suitable line 50 and a valve 52. Radially outside the opening 48, an upper, annular clamping element 56 is provided, which can interact with the upper side of the film material 36. The clamping element is pressurized by a pressure fiber 58. Radially inside the ring-shaped KlermelEmentes 56 , a first male insert 6o is attached to the plate 46 with a necked-in, deeper area 62, the Enaut at 64. A second male part 66 is arranged radially inside the first male part 6o, which is attached to the plate 46 concentrically to the part 6o and to the cleat element 56. The part 66 has a side wall area 68 which is removed from the necked-in area 62 of the male part 6o and is concentric therewith. A 70 b az iff ert e edge, which the e T'lächenbereich 72 of the male part 66 -with the side wall 68 connects, cotellt as-off from the following: fti # .hrung-en ei-clear, one that Volie abscherE5nd , 9 represents the cutting edge of the patrix.

The second male part 66 has a central bore 74 which is aligned with the opening 48 and serves to receive compressed air from the source 54. A plug-like insert 76 is inserted into the bore 74 and extends below the same. The insert 76 has a central bore 78 which is in connection with the bore 74. A piston articular structure 8o is attached to the insert 76 , pointing towards the inside and concentric to the other parts of the patrix. has a central bore 82 with a larger counter bore 84. The piston-shaped structure is advantageously made of an insulating material, such as plastic, so that it does not remove any significant amount of heat from the hot plastic roll, which is pushed between the upper and lower Pormhälft during the drawing process the size and the geometrical shape of the piston 8o are selected so that a very high percentage of the cavity of the mold falls out, the piston 8o serving to mechanically deep-draw the clamped material 36 before air is supplied from the source 54.

A lower, ring-shaped clergy element 86 is arranged opposite the clamping element 86 and has rods 88 pointing downwards, which are actuated by a suitable device go indicated by arrows, which is independent of the device 44 for actuating the porno. During operation of the device, the light elements 56 and 86 should advantageously clamp a separate surface area of the square material 36 so that the piston 84 actuated by the device 42 expands the material 36, which is fixed between the clamp elements, can begin before the under a Ivoimh & lf te 4o moves in the 9 Tal eskoplage to the piston.8o. The lower 3orm 4o essentially consists of a shaped plate 92, which is only shown schematically in the drawing, and which carries a base part 94 which, with a bearing bush 96 penetrating the base part, is arranged on the base plate 92, whereby the bearing bush for bi-way receptacle of an ejector piston 98 with an enlarged head is used. The ejector device 98 forming the bottom of the cavity of the ro =, and it is initially through a fin richtuaiZ loo relatively isolated from the plate 92 ejecting the En leted en ore eugnisse operable from the Po = i. - a generally cylindrical, upright Fonateil lo2 is arranged concen-driven to the base part 94 on the plate imteren 92nd Radially within the pole part lo2 there is an inner porous insert lo4, the conductivity between the two parts being good. The insert lo4 is fixed between the base part 94 and an inner, annular shoulder at the upper end of the element lo2. As can be seen, the protruding molded part lo2 can be uneven from suitable flow tubes, which allow a coolant gel to circulate around the pom. The cylindrical shaped part lo2 has in its middle area, but somewhat closer to the upper end 1181, a shoulder 107 and a threaded part lo8, which extends upwards and serves to receive an external overhanging element llo. The cover sleeve Ilo forms the uppermost T'lächem of the poim and. The branch has a necked-in, upper part 112 which, when actuated, penetrates between the area 62 and the side wall 68 of the male mold, as can be seen from FIG. 2, during the working cycle during the molding.

The enclosed part 112, together with an upper boundary surface 114, forms a film cut-off edge 116 which, firstly, with the corner region 70 of the male mold region 66 , to form a seal and, secondly, to effect a shearing effect on the film 36 during the manufacture and separation of the object = acts. As best from dtn rig. 3 and 4, the surface 114 is arranged at a vertilmlen distance above the area 118 , which is the profiled upper part of the cylindrical element Eslo2 on the right. The surface 12o of the area 118 11 lies opposite the area 72 of the patrix 66 for reasons to be described below. During the deformation cycle, the foil material clamped between the clamping elements 56 and 86 is initially pre-stretched by the movement of the piston relative to the adhesive elements. The mold is then b-actuated by the device 44, so that the parts assume the position shown in FIG. 3. The valve 52 is opened only slowly, so that the film-shaped material is caused by compressed air to detach itself from the piston 84, to come into contact with the die and to assume the final 1P shape. While the positive air pressure is maintained, as shown in FIGS. 3 and 4, the male actuator 42 is rapidly actuated to dispense the fluid between the edges 70 and 1162 as in Pig. 3 and to move the male part in the direction of the stable shown in FIG. Since the air pressure remains maintained, the rolienwerkstofT in contact with the inner Viandung the Pormeinsatzteiles 112 is stopped and the overall fold 34 is oimvorgang by a pressure # zwiselm gefonnt the areas 72 and 12o of the male part or the Förm.

The air pressure gG ensures tight tolerances because it The white material of the roller brings it into close contact with the area 112 on its outer circumference. The exact amount of compression and the exact poim of the palette 34 can, as explained later, result in various ways. It is to be of importance that the operating time interval from the time where the parts 3 illustrated position adopted in Figures and the air pressure is not yet, -geführt, -. Up to the time where the parts in lPig. 4 have assumed the position shown here, is very short and in the order of magnitude of tenths of a second or less. Although at the severed end -des erviälmten hunst-substance, where the Werlistoff between the edges 7o and 116 is sheared off, entering a certain Abkühlungseff ect, the 0 1 he ei ht e c b 0 E) rfl EO h erlabkühl ung s eff ect defi Verks to ff'e s by the rapid actuation of the Foim relative to the patrix overv # unuen and the plastic to one, as from Pig. 1 A tangible, practically solid, one-piece folded joint. As a result of the fact that two opposing surfaces 72 and 12o are provided, it can be. compress and deform the material forming the separating edge to such an extent that it becomes tension-free, which , as mentioned above, has improved point tracking and resistance to stress cracking.

The parts of the device are now moved apart and into their original starting position, the ejector piston lifting the finished object for the purpose of ejecting it out of the tracking zone. The entire work cycle of the ron, i-Lmg, from the throwing of one object to the throwing of the next can be carried out in less than three seconds. A rapid actuation of the device and the simultaneous voiming of the roller during the touching of the object, as opposed to a subsequent cutting off of the object from the foil and / or subsequent forming of the iron, is of economic importance, rig. 5 - shows a somewhat more advanced training educe; amer parts. i, similar parts sinu üii-t, the same reference numerals and the index a numbered. The in 1P.ig. The fold 34 a shown in FIG. 5 has an approximately spherical shape and can be produced by modifying the surface 12 a on the upper end of the insert 118 a, as can be seen in the illustration, and a curved groove 124 in the insert 112 a and been a gE # "iüiaute lUngnut 126 is provided in the Bodeiuläche of Patrizenbereiches 66 a. to 'of the inner string of roimgebung gekiümmtEn region of the? a.lzes is preferably provided a separate insert 130, in a #uelcher veisehene with a suitable threaded bore 128 of the 12atrizenbereiches 1.st. used 166 a the use 13o hät for generating the geaUnschten Torm of the fold 34 a a geklümte, komplanentäre groove 132 which gegeaUb 124 succumbs to the groove. a disadvantage of the device shown in rig. 5 besteht- is that the Insert lo8 can be re-viewed as effectively as insert lo8 shown in Fig. 2. In particular, the upper surface 114 of insert 4a of this, as shown in fig properly screwed on, to obtain a sharp edge 116 suitable for shearing off, the amount of the white material removed by means of washers that are exactly as thick as the amount of the material in the upper area 112 the use of abraded material that can be composed. This is important because the work cycle has to be carried out a million times in production.

The ones in the lPig. A, 6B and 6C shown i #, execution form .vorlie.g, ndvr invention is largely similar to the previous one and corresponding specific details are denoted by the same reference numerals and the index b . Urie can be seen from cLii-n 11guren, a small dent 124 b is made in the part 112 b unmiT, -cG-Ibar radially outside the surface 12o b . When the hatchet 72 b is thus in print with the ID # idberöich the side edge of the container is twofold to the shape of the lPalz edge, whereby the air pressure is maintained, the plastic, which is still in the 'haibwarnerl state, is outwardly into the Pocket 124 b displaced, as a result of which, as can be seen from the Tig, oB and oC, a nose 130 is formed. Names like the one numbered with 136 are often of importance in the case of different types of wood rim that allow ventilation.

In the eg 74 7B and 70 yet another design of a folded edge 34 a is shown.

The portion 118 c has an annular channel with eilier bottom wall 138 which is offset from the rläche o 12o downwards. The two last-named areas are connected to one another by a slightly undercut pond # 14o. When the parts 66 c and 118 c move relative to one another and while maintaining the air pressure on the film, an elevation 142 is formed on the upper regions of the rim 34 a , which rises from the surface 37 a at the same time , rd the radially outer area of the underside of the ralzrandes 34 emit.

The surface 114 c should lie above the milk 12o c. Another embodiment of the invention is shown in FIGS. 8 and 8A . There is another way of producing one variable cross-section of the ralzrandes 35 depicted d. Corresponding details in Figs. 8 and 8A are numbered with the same reference characters and the index d.

The palz edge 34 d, which has been produced with the device shown in these figures, is characterized by excessive compression compared to previous embodiments, so that an inner undercut surface 148 has been formed.

As can be seen from the drawing, the lap edge 34 d also has an outer, heavily undercut face 35 * d and an undercut face 26 d in the side wall, of particular importance in Pig. 8 is the small channel-shaped slot 14u, which is provided in the area 112d of the Po'ijn insert. The exact size and length of the slot 148 can be varied as needed. The slot has the bEwerkenswerte object, a variable C "luerschnittsdicke in the finished ralzrand to produce 34 d. This is achieved in that the cut-off edge 7o d cooperates with the bottom edge of the slot 148, wherever such a slit is present., In the manner This means that there is a delayed section in comparison to the "adjacent" material. Thus there is in the neighboring shaft unmitz: elbar next to the slot 148 a lot of square material that can be gas-immersed and below the slot @ 14o not so thick. This is in 8 a 1'Pig. shown at 150 in plan view. lig. 9 shows a further embodiment ührungsfo in the present invention.] DatsprechencLe'Teile are Llit gl calibrate reference numerals, and the index e bezifrert.

Although in the description of the present invention there was talk of a positive air pressure acting on the inside of the object during the deformation, it is also possible to generate a vacuum on the outside of the container during the deformation. Of importance is merely DAPs will create overall a Druckdifrerenz in the production of the object. When working with a vacuum, it is not necessary that the corners 70 e with the material, as in FIG. 3. 3 , come into contact before the separation process. "If you work with positive air pressure, which works from the patrix side of the rorm, measures must be taken to bring them into close contact with the surface of the roim.
