The container has passage means which are disposed between two side walls and extend from the chamber to the outside of the container, the passage means having a flexible wall with a uniform composition of materials along its entire length and being sealed closed when the container is empty prior to filling.

BACKGROUND OF THE INVENTION

A wide variety of liquid or powder containers are known and available. Such containers may be either rigid so that they are made of a rigid rigid material such as a metal material, glass, paper or plastic material, or they may be made of a flexible material, usually paper or plastic material.

When handling food products, special requirements are placed on the containers in question, in particular with regard to their hygiene characteristics, on the one hand in relation to the packaging of the food products and, on the other hand, in relation to the consumption of these food products. Particularly high demands are placed on handling and packaging sensitive food products such as milk.

SE-B-412 357 describes a parallelepiped paper container in which tubular passage means are arranged in a connecting portion between two side walls. Due to the shape of the container and the certain stiffness of the paper, a self-supporting container is thus formed. The passage means consists of an inner layer of non-fusible material and an outer layer of fusible material that on one side extends beyond the non-fusible material to allow the passage means to melt. Due to the stiffness of the paper and the shape of the container, a cross-sectional shape of the passage means in the container, which corresponds to the side walls, is obtained and creates a practically longitudinal opening or slot when the container is emptied.

The container is of such a type that it is produced and filled simultaneously with the container production from below through the filling tube of the container material. The devices for manufacturing and filling such containers are very large and expensive, and are therefore intended only for large-scale operation.

• β · «· ·

It is very difficult to provide such tubular passage means whose inner layer terminates at one end within the outer layer. In addition, it is an extremely difficult operation to insert the passage means between the side walls of the container when this is done in the filled state.

Very strict requirements are currently imposed on such containers in terms of their environmental impact. It must be possible to produce and transport containers with very little energy consumption and to be handled in an environmentally sound manner after use. In addition, consumers require such containers to be very easy to handle.

As such, the container of SE-B-412 357 is very difficult to handle, as the user holding the container in its filled and open condition is at risk of spilling the contents of the container by squeezing the side walls of the container.

In addition, the container is made of a variety of materials such as paper, polyethylene and aluminum, making it considerably more difficult to handle the container as a waste in an environmentally friendly manner.

As a result of the existence of a large number of different types of containers, there is a need to develop a new type of container that would better satisfy the various requirements currently imposed on such containers.

φ «φ φ arranged so that the passage means 16 'form a connection with the welded side walls 12' along the connection portion 20 '. Thus, the passage means 16 'may have the same wall thickness as the side walls 12', and in addition no inner material having a higher melting point is required.

In the lower region of the container 10, the bottom wall 14 is shown with its upwardly extending fold line 15 and two side walls 12 which are joined to the bottom wall 14 by welding along the lower connecting portion 24.

Referring to Figure 8, a particular embodiment of the support means or handle 30 of the container 10 is shown. A deformation zone 50 comprising deformation regions 54 and 56 at each of the two apertures 34 and 36 is shown. in which the two side walls 12 lying side by side are not connected to each other. As a result, the deformation regions 54 and 56 will have great flexibility and flexibility and will extend along the edge-facing side of the orifice region 32. These deformation regions 54 and 56 will deform if the user holds the container 10 by hand in the opening region 32. This prevents the side walls 12 around the opening region 32 from being cut into the hand of the user.

In addition, Figure 8 shows reinforcing means in the form of a gas-filled channel 52 which is arranged between the opening region 32 and the edge of the connecting portion 20. As a result, the stiffness and strength of the support means 30 are increased, even though the side walls 12 are made of flexible and flexible material. Since the channel 52 is filled with gas, preferably air, it does not occur here

No. 4,444,444 to add any additional material that would make the container 10 heavier, and handling the container 10 after use could be more difficult.

The containers of the present invention, shown in the figures of Figures 1 to 8, are in a filled state intended to be stored and stored while standing, and are particularly suitable for consuming liquid food products such as milk or juice. A preferred size is about 1 to 3 liters.

Referring to FIG. 9, a third embodiment of a container 110 according to the present invention is shown.

In this construction, the container 110 is adapted to be suspended to dispense its contents, and is particularly suitable for larger quantities of about 5 to 15 liters and for use as a dispensing device. The preferred field of application is as a drinking water dispensing device. The container assembly 110 largely corresponds to the above-described first embodiment of the container 10. The main difference is primarily that the container 110, unlike the container 10, is used in an inverted position so that it has an upper wall 114 that corresponds to the lower wall 14, means 116 arranged at its lower end.

The top wall 114, together with the side walls 112 of the container 110, points upwardly and provides support means 130 that comprise flaps 132 in which apertures 134 are formed. As a result, the container 110 can be hung on the retaining bar 60 in connection with its storage, transport and with publishing.

• · • ·

Referring to FIG. 10, the structure of the container 110 is shown at the lower end thereof, the closest side wall 112 being removed for clarity and the passage means 116 are shown in longitudinal section.

It can be seen from FIG. 10 that, in the same manner as described above, the passage means 116 along one half of its perimeter is connected to one side wall 112, and along the other half of its perimeter is connected to the other side wall in the coupling portion 120 of the container 110. However, the passage means 116 in this embodiment extends some distance into the chamber 140 of the container 110 from the connection portion 120. At the same time, the side walls 112 form a projecting additional portion 113 that surrounds the passage means 116 to form an annular projecting blind channel 142 around the passage means. 116 in chamber 140.

The connecting portion 120 is transverse connected to the passage means 116 and is provided on each side of the passage means 116 with a curved portion 122 and an edge portion 124 extending from the curved portion 122 parallel to the passage means.

In the position shown, the passage means 116 is in the emptying or filling position, with the passage means 116 open both at its inner end 117 and at its outer end 118. However, in connection with the manufacture of the container 110, the outer end 118 is sealed. In connection with the filling, the container 110 is opened by cutting or shearing off the sealed closed outer end 118.

After filling, the container 110 is closed such that the inner end 117 of the passage means 116 is sealed, as shown in Figure 11, where the passage means 116 is shown in a longitudinal section perpendicular to the section shown in Figure 10. A pair of hot stamping jaws 70 is pressed against the sidewalls 112 as shown by the double arrow 72. ^In Figure 11, the state immediately thereafter is shown. In order to prevent the side walls 112 from joining the passage means 116, the inner surfaces of the passage means 116 are preferably made of a material with a lower melting point than the inner surface of the side walls 112 and the outer surface of the passage means 116.

If the container 110 is to be emptied in the next stage, the passage means are opened by means of stitching means to the position shown in FIG. 10. Then the container 110 can be emptied by means of valve means (not shown) having a cylindrical peripheral surface. Then, the liquid in the annular projecting blind channel 142 will pressurize the passage means 116 against the valve means under pressure, thereby providing a leak-proof seal.

The container according to the above-described embodiment of the invention may advantageously be made of a flexible material, a plastic material being particularly recommended. Plastic materials are particularly advantageous as they are heat-sealable in each case by the respective sheets. The preferred plastic material comprises a base layer of a polyolefin material with a filler to form a filler

is preferably chalk. It has been found that such a material exhibits good barrier properties, in particular against gas ingress, at a low cost. It is also possible to form a gas barrier of EVA or EVOH. The material thickness of the subject containers is preferably in the range of 100 to 200 μιη.

Manufacture of containers

The following is a description of the manufacture of a container of the type described above with reference to Figures 1 and 2.

FIG. 12 shows how the container walls are attached to a common belt. Two identical sidewall strips 212 are run parallel to each other in opposite directions along the production line. At the same time, the bottom wall strip 214, which is folded into a double-walled shape, is sandwiched between the two side wall strips 212.

Referring to FIG. 12, a mounting station 240 is shown, also showing how the three plastic strips 212 and 214 are joined and secured to each other at the bonding station 220 by hot sealing to form a container belt 210. This hot-melt operation is performed with the help of hot-pressing jaws 218. In the punching station 225, handles and portions of material disposed between the containers are punched.

Then, the container belt 210 enters the insertion device 250 through which the passage means 16 are mounted. The tubular belt 216 is unwound from the storage spool 209 and cut into the passage means 16, which are then inserted between the side walls of the belt via the insertion device 250 to forming the finished containers 10 in a container belt 210 that is wound onto a storage reel 230.

Referring now to Figure 13, parts of the assembly station 240 are shown in more detail, showing how the tubular strip 216 is fed via the feed device 242 to the insertion device.

250 is cut into passage means 16 of appropriate length by means of a cutting device 246.

The inserter 250 comprises an annular idler 251 which is intermittently driven by a drive motor 248 and provided with a gripping slot 252 extending around the periphery of the annular idler 251 in which the passage means 16 are retained.

The circumference of the annular wheel 250 further extends in an insertion position near the container belt 210 to insert the passage means 16 between the side walls 12 of the containers 10. The assembly station 240 further comprises a separator device 60 for separating the side walls 12 from each other when inserting the passage means 16. The separating device 260 comprises two vacuum cylinders 262, one on each side of the container belt 210, which are spaced apart from the container belt 210 and which are connected to a vacuum source (not shown). Apertures 264 are formed at the periphery of the vacuum cylinders 262 in which vacuum is maintained by a vacuum source causing mutual pressure to be generated.

separating the side walls 12 from each other as shown in FIG. 13.

In addition, the assembly station 204 includes a first coupling 270 and a second coupling 280. The first coupling 270 has two hot pressing jaws 272, one on each side of the container belt 210, for connecting two side walls 12 to each other. and also to the passage means 16 along the open connection portion 20. The second link device 280, which is arranged downstream of the first link device 270, also has two hot pressing jaws 282, each of which is disposed on one side of the insertion passage means. 16 to fuse them.

The suction force from the vacuum cylinders 262 is applied when both the container belt 210 and the periphery of the insertion device 250 are moved in the direction of movement of the container belt 210 so that the passage means 16 are inserted obliquely between the side walls 12. When the passage means 16 are perpendicular to the belt 210 of the container, both the movement of the container belt 210 and the movement of the insertion device 250 are stopped, while the effect of vacuum on the vacuum cylinder 262 is interrupted.

In this stationary position, the pressing jaws 272 of the first coupling 270 are pressed against the outside of the side walls 12. At the same time, a new piece of tubular strip 216 is inserted on the other side of the insertion device 250 into the receiving slot 252 of the circular insert wheel 251, then cut to form new passageways. The non-moving time 16 is also utilized by a second coupling device 280 which simultaneously fuses the passage means 16 and thereby also the auxiliary vessel 10 in a stage located in the direction of movement.

In addition to the aforementioned components and devices, the container manufacturing apparatus includes a feed device 290 in the form of two rollers 291 and a separating device (not shown) to control the feed to ensure the correct position of the passage means 16. In an alternative embodiment the outer end of the passage means 16 is sealed before the passage means 16 are inserted between the side walls 12.

As shown in FIG. 12, the completely finished containers 10 are wound onto storage coils 230. A significant advantage of these containers 10, especially when used for food products, is that they can be sterilized by radiation in a very simple manner, by exposing the receiving coils 230 to an axially directed radiation, in which case the radiation passes through the interior of the containers 10 and only has to penetrate the joints in the axial end portions (not shown in the illustrations of the receiving coils 230).

Filling the container

FIG. 14 shows a side view in the direction of movement of the container filling device 300 of the type described above with reference to FIGS. 1 and 2, in particular liquid. This apparatus 300 will now be described in another exemplary embodiment for filling milk, but is also suitable for filling other liquids and powders.

The container filling device 300 includes support means 310, a filling channel 315 that is connected to a storage tank (not shown) and consists of a deformable tube 320 provided with a filling nozzle 325 at its lower end, and a crimping means 330 which are arranged around the throttle portion 322 of the deformable tube 320, and including a support device 331 disposed on the first side of the deformable tube 320, and a crimper member 332 disposed on the opposite side of the deformable tube 320. 14 which is shown in FIG. 14 is omitted.

The support means 331 of the squeezing means 330 is rigidly connected to the support means 310 and forms a concave curved squeezing surface 333 facing the deformable tube 320. The squeezing member 332 is circular and is hinged to the support means 310 in an asymmetrically rotatable manner. Thereby, the squeezing member 332 forms a convexly curved squeezing surface 334 directed towards the deformable tube 320 and the support device 331.

The crimping member 332 is rotatable in the manner indicated by the double arrow 335, thereby opening the feed channel 315 by a combined downward and outward movement from the deformable tube 320, closing the feed channel 315 by a combined upward and inward movement towards the deformable tube 320. Since the closure occurs as a result of the combined crushing and upward movement, a pressure that is lower than atmospheric pressure is generated in the deformable tube 320 downwards

9 from the squeezing means 330, thereby preventing dripping from the filling nozzle 325 between the individual filling operations.

The filling device 300 for filling the container 10 also includes control means (not shown) that control the opening and closing of the filling channel 315 by the squeezing means 330. The control means are also connected to a measuring device (not shown) for measuring the flow rate of liquid. The control means is arranged such that the measurement is initiated at the same time as the filling channel 315 opens and that the filling channel 315 is closed after a predetermined amount has been measured. The measuring device may be constructed in one of several ways, for example for weighing the container 10 during filling, for measuring the volume flowing through the filling channel 315 or for measuring the time elapsed since the opening of the filling channel 315.

The support means 310 carrying the deformable tube 320 and the squeezing means 330 are vertically adjustable in the frame 340 in such a way that the filling nozzle 325 can be inserted into the container 10 to initiate the filling operation and can then be removed from the container 10 after filling. .

Arranged on the frame 340 are opening means 350 in the form of two pivotable opening arms 352, at the ends of which suction cups 354 are arranged. These suction cups 354 are connected to a vacuum source. By rotating the suction cups 354 through the pivotable opening arms 352 relative to the sides of the passage means 16 of the container 10, and then applying a vacuum to the suction cups 354 while simultaneously opening the suction cups 354. φ φ φ

The arms 352 rotate slightly outwardly, the passage means 16 open so that the filling nozzle 325 can be inserted into these passage means 16 by moving the support means 310 downwards.

Also shown in Figure 14 is a pair of conveyor arms 345 that are arranged on rotatable conveyor bars 346 that are adapted to reciprocate. As the conveyor belt 210 is conveyed, the conveyor arms 345 are pivoted to engage the conveyor belt 210, whereupon the rotatable conveyor bars 346 perform an impact movement in the direction of travel of the conveyor belt 210 to move the conveyor belt 210 thereafter. 345 rotated away from the belt 210 of the containers 10 and the transport bars 346 return to their initial position to repeat the entire process.

The filling nozzle 325, which is shown in greater detail in the Figures 20 and 21, has an end portion 326 of elongated cross-section that tapers conically in the direction of its axis to an elongated outlet 327 with opposing edge portions 328 which touching. The end portion 326 also tapers slightly in the longitudinal direction of the longitudinal cross-section, as shown in Figure 20.

The filling nozzle 325 is made of a resilient elastic material, preferably a plastic material, such as silicone rubber, and is self-closing, that is, the opposing edge portions 328 of the elongate outlet 327 abut each other so that they close the outlet 327 tightly. external force applied.

The filling nozzle 325 is provided at its end opposite the end portion 326 with a connecting portion 329 for connection to the filling channel 315. The filling nozzle 325 thus formed is particularly suitable for insertion into the passage means 16 of the container 10 and is sealed within the passage means 16. saved.

Figure 15 is a side elevational view of the charging device 300 of Figure 14. A chamber 360 that is disposed around the filling nozzle 325 and the passage means 16 of the containers 10, wherein the chamber 360 is provided with a rail 362, is shown. which are passed through the passage means 16 through a bellows 364 surrounding the filling nozzle 325 and a supply channel 366 for supplying a sterile gas such as hot sterile air.

Referring to FIG. 15, the container belt 210 is fed to the feed device 300 in the direction of the arrow 3 to indicate the direction of travel of the container belt 210. In position A, the container 50 is closed, the passage means 16 of which are sealed. opening means in the form of a cutting device 370 with a motor 374 and a rotatable cutting blade 372 disposed on each side of the container belt 210, only one of which is shown here, are arranged in the rail 362 for opening the container 10 by cutting off the sealed end edge 18 of the passage means 16.

Downstream of the cutting device 370 as viewed in the direction of the arrow 3 there is a feed nozzle 325 of the feed channel 315, and a sealing station 380 is shown one step further, which is shown in greater detail in Figures 18 and 19, in greater detail. and which includes two hot pressing jaws 382, also shown in Figure 16, and mounted on support arms 384 for sealing passage means 16 of filled containers 10.

The rail 362, the shape of which is shown in greater detail in Figures 16 and 17, is elongated and has a substantially rectangular vertical cross-section with a slot 363 formed on its underside and in which passage means are guided. The slot 363 extends near the feed nozzle 325 into the elliptical aperture 365 to allow opening of the passage means 16 and insertion of the feed nozzle 325 into these passage means 16. In addition, the rail 362 is further adjacent the feed nozzle 325 by a cylindrical connecting portion 368 arranged on its upper side and which is intended to receive the bellows 364.

In operation of the filler device 300, sterile gas flows into the bellows 364 through a feed channel 366 and further flows into the rail 362. This gas then exits through the slot 363. The bellows 364 provides a sterile environment around the filler nozzle 325, which filler nozzle 325 can be lifted and lowered simultaneously . Using chamber 360, it is ensured in a simple and reliable manner that filling is performed in a sterile environment.

When filling the empty and pre-sterilized container 10, the container 10 is first placed in a sterile environment in a rail 362 where the empty container 10 is first opened in the cutting device 370. The open container 10 is then fed to a filling nozzle 325 near it.

99, the opening means 350 open the passage means 16, whereupon the filling nozzle 325 is inserted into the passage means 16. In this connection, the crushing means 330 is opened and the container 10 is filled with milk, thereby increasing its volume, the liquid supplied to the vessel 10.

After measuring a predetermined amount of liquid, the squeezing means 330 are closed accordingly. On closing, the deformable tube 320 near the filling nozzle 325 generates a pressure lower than atmospheric pressure, thereby causing its longitudinal outlet 327 to be tightly closed. The container 10 is then fed further to the sealing station 380 where it is resealed.

Due to the fact that the polluted air from the environment cannot in any case enter the container 10 after it has been sterilized, an extremely hygienic environment will be ensured for the liquid contained in the container 10.

When cleaning the filling device 300, the rail 362 together with the bellows 364 is removed by a release device 367. These components are then cleaned in a separate bath. A cleaning tray (not shown) with a tubular connection is arranged around the filling nozzle 325, the cleaning agent circulating in the filling channel 315 and around the filling nozzle 325. Then, the cleaning tray is removed and the rail 362 together with the bellows 364 is put back in place.

by means of the collection means provided

The slot 363 of the rail 362 is then sealed by a gas-tight outlet, whereupon the filling nozzles 325 are lowered into the filling position and sterilized with hydrogen peroxide (H ₂ O ₂ ), the gas being supplied through the inlet duct 366 and discharged through the collection means. After removal of the collecting means and after allowing milk to flow through the feed channel 315, production can resume. In this way, the filling device 300 can be easily cleaned and kept clean so that good hygiene conditions are ensured.

Although only container manufacturing and filling devices having separate passage means interposed between the side walls of the container have been described, it should be emphasized that by making appropriate modifications these devices can also be used to produce containers whose passage means are integrally formed with the side walls of the container . Thus, the scope of the invention is defined solely by the following claims.
