can be infected, which is usually a prerequisite that the bottles are cleaned and sterilized before they are filled Need to become. Additional aids must therefore be made available in the filling plant or station to enable such a To enable the bottles to be cleaned, sterilized and the like, which significantly increases the cost of filling the bottles and thus worsens the achievable efficiency. For the Actual filling therefore means a procedure of this kind sometimes considerable additional costs.

Taking into account the above, the The invention is based on the object of submitting a proposal, as in the case of a transport of bottles from the manufacturer to a filling plant or station can be dispensed with, cleaning, sterilizing and the like of the bottles in this before filling To have to go through, so the actual bottling is essential to simplify and thereby their efficiency by reducing costs to increase. The invention is also based on the object, with regard to the production of bottles, the amount of Reduce waste material.

This object is achieved in that, according to the invention, a method for sterile or sanitary packaging of an object in a hollow vessel and a device for carrying out this method as well as a hollow vessel produced by this method are proposed.

According to the method according to the invention for sterile or sanitary packaging of an object in a hollow vessel, first Unified or combined or connected hollow vessels produced as raw materials. Each combined Hollow vessel comprises individual vessels, which in peripheral side

0 0 9 017/1355

walls of opposing opening areas continuously are connected to one another or joined to one another, with at least at the joint of two adjacent individual vessels if necessary a weakening point can be provided to prevent the separation of these To ease calmly. The cavities of these individual vessels are one below the other The opening areas are only connected via channels within these side walls, and the individual vessels are completely closed except for these opening areas. The combined hollow vessels come then to the filling line or station for dispatch and are in this at a point in time shortly before bottling at the joint the side walls in the area of the openings separated to individual vessels as secondary products. These individual vessels can alternatively, they can also be subjected to a further molding process prior to filling in order to obtain bottles. It can thus be seen that up to the actual filling of the vessels or up to the introduction of an object to be packaged in these the interior of the vessels or the bottles shaped in this way are completely protected against the ingress of dirt or germs, so that any cleaning, Sterilization and the like is not necessary and the filling of the vessels or Bottles is uncomplicated, the vessels or bottles are filled, then its opening is finally closed. The following advantages can thus be cited in detail for the invention:

(a) There is no longer any need to clean and sterilize the vessels just before they are filled, and that’s the case it is no longer necessary that corresponding auxiliary equipment must be made available in the filling system or station.

The actual filling can be simplified considerably and a higher degree of efficiency can be achieved with it, which is the case with the end product results in a cost reduction.

(b) The combined ones, which were kept aseptic up to a point in time shortly before the filling and protected from the ingress of dirt Hollow vessels can be used over a long period of time in this

009817 / 1-356

stood stored their cavities completely closed to the outside be, this storage is space-saving.

(c) Since it is possible to store a large number of such combined hollow vessels in a limited space, a supply for Available, which can be used, if, in individual cases, more vessels have to be filled than the rule is equivalent to.

(d) Since each combined hollow vessel is composed of individual vessels, which in circumferential side walls of opposite one another Opening areas continuously connected to one another or are attached to one another, each individual vessel serves as a lid for the other, and the separation has been carried out,

|) Individual vessels are then obtained from these hollow vessels. That for the

The material needed to manufacture these individual vessels takes place exclusively only for shaping this use, i.e. there is no waste material whatsoever. The ones transported after manufacture and stored products are therefore exclusively the vessels themselves, so that a highly efficient transport and an equally rational storage is ensured.

(e) The hollow vessels manufactured according to the invention are attached to the shock. place the side walls in the area of the openings to form individual vessels separated. These individual vessels can, if necessary, be shaped, whereby they are heated and exposed to air pressure are. The individual vessels formed in this way are used as bottles, when they are full, their opening is closed. In this case, the individual vessels are filled according to their Shaping into bottles of large capacity through application of heat and air pressure, which can take advantage of the fact that the individual vessels, which have not yet been formed into bottles, are stored in a space-saving manner can be. When the individual vessels are formed into bottles, the heating also results in sterilization of the bottles, so that after molding the bottles without difficulty

"-. ■" ■ .00 98 1 7 / 1-366

can be filled.

According to a further partial feature of the present invention, creates these combined or combined or connected with one another Hollow vessels, which are composed of individual vessels connected to one another or joined to one another, which on their mutual abutment points are each provided with at least one weakening point, which is much weaker than the adjacent material areas on both sides of this point. Alternatively, the joint can be marked with a line of weakness be provided throughout the circumference, which acts as the weakening point and which is much weaker than the neighboring ones Material areas on both sides of this line of weakness. In this way, the combined hollow vessels can be attached to them Separate weak points very easily into individual vessels. The individual vessels can therefore be used immediately at the point of filling can be obtained from the combined hollow vessels without the use of special cutting devices. With these combined According to a further partial feature of the invention, hollow vessels can be the cylindrical wall at the joints between the individual vessels protrude inward, so that there is an acute angle to the longitudinal surface lines of the vessels, to both Sides of each joint and in particular the line of weakness of each joint, creating a transition area, whereby the separation of the combined hollow vessels into individual vessels is facilitated.

According to an alternative partial feature of the present invention the cylindrical wall of the combined hollow vessels can protrude outward at the joints between the individual vessels, so that, in Seen in a longitudinal section, slightly convexly curved transition areas on both sides of a joint and in particular towards

formed on both sides of a line of weakness provided in this be, thereby also separating the combined Hollow vessels to individual vessels is facilitated. Come the individual vessels in the way they are used when the combined hollow vessels are separated, then there is no need for the There is no need to modify the shape of their openings even if the individual vessels should have been carried out Separation of the combined hollow vessels are subjected to shaping.

According to a further partial feature of the invention, this creates com- " bound hollow vessels, in which the cylindrical wall on the Joint on both sides of this and in particular on both sides of a line of weakness provided in this ring or protruding outward in the shape of a bead, the opposite side regions of each of these protrusions being close to one another lie. After the separation of such combined hollow vessels too These individual vessels become individual vessels along the weakening lines Shaped into bottles, the opposite sides of the annular or bead-shaped projection of each individual vessel are pressed against each other, so that the between the bottle an opening of high strength is obtained, whose Wandsiürke is larger than that of the rest of the vessel.

According to yet another individual feature of the present invention, creates these vessels, each of which at its opening opposite end has a melted area, which thereby is shaped that at this end a collection of material was made in the direction of the vessel axis. The distance between the Axis and the outer end of this molten area

ö-00e 17 / 13-66

smaller than that between the axis and the side face of the Vessel, creating a uniform over its entire bottom surface or even closure is obtained.

Other features and advantages of the present invention will become apparent

The method according to the invention for sterile or sanitary packaging of an object in a hollow vessel will first be described in more detail with reference to a first exemplary embodiment of a device suitable for carrying out this method according to FIGS. 1-6. In these figures, 52 denotes a cylindrical body which, heated at a high temperature, is continuously extruded from an extruder 51. Outside this cylindrical body 52 and around it, suction holding devices 53, 54 for holding this cylindrical body are arranged, which hold a suitable distance from one another in the longitudinal direction thereof. Each holding device 53, 54 consists of an annular body 57 or 58, which has a cavity 55 or 56, which is open to the cylindrical body 52 via several suction openings 59 and 60, respectively. On the circumferential side outside this cavity 55 and 56, each ring body 57 and 58 has a cooling water channel 82 and 83, respectively. A tube 61 or 62 is connected to each of the cavities 55, 56 and is connected to a suction device (not shown) in order to generate the suction effect. The cooling water channels 82, 83 are also connected via pipes to a suitable cooling device, not shown. Between the holding devices 53 and 54, collection bodies 63 are also arranged, which face the longitudinal direction of the extruded, cylindrical. Body 52 are perpendicular to three different locations in three radial directions. These collection bodies are in the form of home base plates, with the smallest acute angles against the

0098 ir / ms

cylindrical body are directed. The S _a ramlungskörper 63 can be by means of a not shown Anstriebseinrichtung simultaneously to the cylindrical body toward and move away again, wherein a pinch-off 65 is arranged so that the collection body 63 when they are moved simultaneously towards the cylindrical body 52, able to press the wall area of the heated, cylindrical body 52 facing them against the central axis in order to finally form a closed area 64 by bringing about a melting process, with the result that a closed body 79 is formed, namely in a position below this collection body 63. A cutting device 78 is arranged between the collection bodies 63 and can be moved towards and away from the closed area 64 formed by the collection bodies 63. This cutting device 78 consists of a holding body 77 which can be moved by a drive device (not shown), an electrically heatable heating body 90 within this body 77 and a knife 98 with a cutting edge 92 which is attached to the front ends of heat-conducting bodies 91, which are very warm Good conductive material are made and extend from the heater 90 forward.

Below the lower holding device 54 64 semi-circular body 66 are arranged around the sealed body 79 around successively CLOSED scenes between two regions which inner concave surfaces 67 having, facing the body 79.. The semi-circular body 66 are attached to the ends of piston rods 70 of hydraulic cylinders 69 which are in turn mounted on a plate 68, so that this body 66 by the piston rods 70 to the sealed body 79 zm and this again can be moved away. Lines 71 and 72 are connected to the hydraulic cylinders, so that when appropriate

0Ö9Ö17 / 13S6

Control of the flow of the pressure medium, the piston rods 70 are moved back and forth accordingly »The radius of the inner, concave surfaces 67 of the semicircular body 66 is approximately equal to the outer radius of the closed body 79, so that when these semicircular bodies 66 come closest to each other have been moved and their end surfaces 73 abut one another, the inner, concave surfaces 67 hold the closed body 78 between them, - The semicircular bodies 66 still have on their inner, concave surfaces 67 at a circumferential, concave point in their longitudinal direction Grooves 75 which are essentially triangular in cross-section, the tips lying in the middle being rounded, as indicated at 74. These concave grooves 75 are connected to suction pipes 76 which are connected to a suction device (not shown). Inside the semicircular body 66 , cooling water channels 84 are also formed, which are in connection with a cooling water device (not shown), namely via pipes 85 and 86. A device is thus created here which allows the formation of weakening points.

The individual collection bodies 83 and the two semicircular ones Bodies 66 can at the same time move against the cylindrical body 52 or the closed body 79 and away from it again move. The cutter 78 is controlled so that it can be moved against the closed area 64 after the Collection body 63 have formed this and have been withdrawn. The holding devices 53, 54, the clamping device 65, the device generating the weak points and the cutting device 78 are combined to form an assembly unit. In operation, this assembly unit moves down at the same speed moves, with which the cylindrical body 52 ex-

is truded, the individual components have completed their work, then this assembly unit is back up in your Starting position moved back.

In the operation of the device is therefore continuously from The cylindrical bodies 52 extruded from the extruder 51 are clamped by the device 65 at equal mutual intervals so as to form the closed portions 64. At the time when these closed sections 64 are formed the cylindrical body 52 is held by the holding device 53 to prevent lateral deflection, while at the same time cooling water flows through the channels 82, 83, to cool the area of the body 52 to which the Section 64 is formed. The semicircular bodies 66 are moved against the closed body 79 so that their end faces 73 come into mutual contact, so as to make the closed one To hold body 79 between the inner, concave surfaces 67, which is then applied with a suction force, which This suction force acts via the tubes 76 becomes the heated to a high temperature wall of the closed body 79 in the area of the inner, circumferential, concave grooves 75 brought into contact with these, so that this wall part deformed into a convex cross-sectional shape. During this shaping, because of the presence of the projections 74, the between The wall part lying on the two convex formations is kept smaller in its diameter or in its thickness than the convex ones Formings, whereby a line of weakness 80 is formed, which has a significantly lower strength than the convex Formings · Instead of a weakening line, this Wall part can also be provided with at least one weakening point in the same way. So be this way between the weakening line 80 or a corresponding one

00 9017/135 5 " ¹² "

SchwäGhysigpunkt and the closed sections 64 obtained by melting, individual vessels 88 are formed, which are connected to one another or joined to one another at the weakening line 80, the closed body 79 forms a combined hollow vessel. The semicircular bodies 66, which are cooled by the water flowing through the KUhI water channels 84, cool this combined hollow vessel. After the closed section and the line of weakness 80 have been formed, the cutting device 78 is actuated in order to cut the upper, closed section by means of the cutting edge. 92 at the end of the knife 93 heated by the heating element 90 to cut through in a central area,

so that a combined wooden vessel 79 is obtained, as shown in FIGS Fig. 5 and 6 is shown .. The radiator 90 is through the Heating elements 91 heated. As shown in FIGS. 5 and 6, has the combined hollow vessel 79 obtained has a closed section 64 at each of its two ends and the line of weakness or a corresponding weakening point is on the circumferential side Butt of the individual vessels 88. These individual vessels 88 receive one by separating the combined concealer vessels * 79 along its weakening line 80, as indicated in dash-dotted lines. Each individual vessel 88 then has an opening 81 at its one end, while its other end through the

'Section 64 is closed. The individual vessels 88 obtained in this way can then be filled with a substance via the opening 81 while maintaining their shape or, if necessary, changing their shape after filling, the opening is closed *

It can thus be determined that about the Formation of the combined hollow vessels kept the individual vessels completely free of germs until shortly before filling and before penetration can be protected from foreign substances · The filling making itself extremely easy by doing any cleanup and the individual vessels are no longer sterilized to needs · It is recorded that they invention the Above mentioned advantages (a) to (e) can be achieved.

With reference to FIGS. 7-9 it will now be described how the individual vessels at the point in time after their separation from the combined hollow vessels and before they are filled into a different shape deform Jasen. 7 and 8 show a suitable one Shape. At the side of a base frame 101, which is a horizontal Can rotate axis intermittently, mold frames 102 are arranged, which can be moved toward and away from each other and are substantially parallel to the horizontal axis of rotation of the frame 101. These mold frames 102 each have an inner one Form surface 103. If these two mold frames 102 are in mutual contact, then limit the inner mold surfaces a cavity 104 which is closed to the right by the frame 101 and opened to the left via an opening 105. Laterally the mold frame 102, a cover frame 106 is arranged, which can be moved back and forth relative to the frame 102, A holder stands over the side surface of this cover frame 106 107, which extends through the opening 105 into the cavity 104 can move in when the cover frame 106 against the mold frame 102 is moved and finally comes into contact with them

The holder 107 is provided with air outlet openings 108 near the cover frame 106, which are connected via an axial channel 109 to a fan, not shown. The cavity 104 is in communication with the atmosphere via a vent hole 110 in the base frame 101. The reference number 112 denotes an individual vessel consisting of a thermoplastic material, which is closed at its end at 114 and was obtained by separating from a combined hollow vessel at its weakening line.This individual vessel 112 is first placed over the holder 107 and then heated by means of a suitable device before it is then moved together with the holder 107 through the cover frame 106 into the cavity 104 of the mold until its neck 113 rests on the fora frame 102, which is then closed. If the cover frame 106 has been brought into contact with the phone frame 102, then air is passed through the axial channel 109, which flows out through the openings 108 into the cavity 115 of the individual vessel 112, so that the individual vessel is expanded and finally the fox «Assumes which is predetermined by the shaped surfaces 103. This is illustrated in FIG. 8. The air trapped in the cavity 104 is thereby discharged via the bore 110. The individual vessel thus formed is then brought out of the mold by first moving the cover frame 106 to the left and then moving the frames 102 apart. The individual vessel obtained has a shape according to FIG. 9 , where it is denoted by 116. This individual vessel 116 is thus obtained by first starting from a combined hollow vessel, which is composed of individual vessels which are connected to one another or which are connected by a line of weakness. are joined to one another and then separated into individual vessels 112, each of which has an open end and is then reshaped into the shape of this vessel 116. The vessels 112 provided with a closed end are therefore free of germs up to the time of this formation - .. ■■. ■ '- 15'-

point, while its other end is provided with an opening, Via which its hollow space can be filled with a substance · By the line of weakness 208 protrudes inward at an acute angle, If the force to be used to separate the combined hollow vessel is significantly reduced, this also takes effect at the inner peripheral edge of the weakened area 208 at The one that forms an acute angle and protrudes inwards Weakened area 208 also produces a notch effect in the inner circumferential edge if the combined hollow vessel has one Is subject to bending, it is in particular this notch effect that which makes the separation of the combined hollow vessel 204 much easier. This weakening area 208 is also used the precise guidance of a cutting device such as a knife Or the like. Should such a machine separation of Hollow vessels come to use. It is thereby also for such a magshin®ile separation for an accurate and facilitated Separation process taken care of »

The convex peripheral edges 209, 210, which have outwardly protruding, uniformly curved surfaces and which are located on both sides of the weakened area 208, increase the strength of the wall on both sides of the weakened area, which is also protected at the same time, which factor is particularly important for the transport and storage of such combined hollow vessels, should they be subjected to an unexpected deformation that it is then no longer necessary to subject the openings of the separated individual vessels 211 or 212 to a shaping process when the individual vessels are filled; : _; _ - -_ - T7 ^: -

Use come as they arise through the separation of the hollow vessels. Because of this factor, the separated individual vessels after filling with a suitable closure element which is fitted over their opening.

It should therefore be noted here in connection with the embodiment according to FIG. 11 that it is for the separated individual vessels not required for use as a container? the vessel shelf to form a convex circumferential edge, rather the convex circumferential edges 209 and 210 on both sides of the already produced in the manufacture of the combined hollow vessels Weakened area 208 are used to form a cap or a lid to record. Finds the single vessel as a beverage bottle, like a milk bottle or the like, use its opening when drinking comes into contact with the lip from the bottle, then it serves convex edge or vessel rim as a smooth support surface for the Lip.

FIGS. 12-14 show a further embodiment according to the invention. The combined hollow vessel 304 shown in FIG. 12 has closed ends 301 and 302, its cavity is denoted by 303 and its wall is provided with an area of weakness at 305. The ends 306 and 307 on both sides of this weakened area 305 protrude outwards, around folded walls 309 and 310 to form, which include acute angled areas 308 between them, on both sides of the weakened area 305 are therefore annular projections 311 and 312, each at an acute angle educated. The combined hollow vessel 304 is formed along the weakened area 305 between these annular projections 311, 312 separated in order to obtain individual vessels 313 and 314, which are each have a closed end. This by separating the hollow vessel 304 obtained individual vessels 313, 314 are then
