Definitions

  • a machine for filling, compressing and closing packages of the type comprising an outer package of stiff material and an inner package of thin weldable material so shaped that the inner package at its upper edge in the unfilled state contacts the inner side of the upper edge of the outer package without being attached thereto includes an arrangement for inserting each unfilled package into a mold, lowering a clamping member formed with inner and outer frame parts down over the package-containing mold such that the inner and outer frame parts clamp the upper edges of the inner and outer packages, the clamping being retained during subsequent filling of the package and compression of the material within the package, the compression being effected by a piston or
  • the clamping frame is thereafter withdrawn, followed by further treatment of the package, such as evacuation, final closing, etc., after which the package is separated from the support ing mold.
  • the clamping frame preferably comprises an outer frame which fits down around the upper edge of the composite package, and inner side parts which are pivotably mounted on the outer frame to pass downwardly into the package.
  • a pressure frame pivots the side parts about their axes to complete the clamping of the upper edges of the package during filling, compression, etc.
  • the two parts should thereby be combined with each other at least along the opening edge, and the closure of the inner package could be made by means of a piece of plastic or metal foil or the like, pressed down in the package, so that it will contact the compressed material by an even surface and approach the inner side of the upper edge of the inner package.
  • the outer package will comprise more material than correctly would have been required for receiving the compressed inner package with its material.
  • the outer package will lack support from the hard inner package after the compression, and it will therefore easily be subjected to a deformation, which is not desirable. After such deformation the package as a whole will loose is stackability. The buying general public easily will understand that the inner package is' loosely applied in the outer package as an error.
  • the new kind of packing proposed herein has for its purpose to remove these disadvantages, such that the package is not made essentially greater than required for receiving the compressed inner package, but the product in this is compressed by mechanical pressure in advance, before it is introduced into the vacuum chamber. After such mechanical compression the product will remain in its compressed state except for a very unessential resilient movement in the order of magnitude of about 2 or 3 percent, which means that if one has decreased the volume of the packed material by mechanical compression to for instance 80 percent of the volume after shaking, and thereafter releases the mechanical pressure, a resilient return will take place by 2 or 3 percent, whereas the compression during careful handling of the package will remain by 17 to 18 percent or with other words the inner package and the I product packed therein will retain a volume of 82 or 83 percent provided by compression.
  • the inner package which has to be made from a rather thin and soft material must not be connected to the outer package, at least at its upper parts.
  • a danger will exist that the inner package is sucked to follow the material falling down and be folded and will shrink in altitude, so that its upper edge will no longer be at the expected level.
  • this action may enter at the following compression. It is then obvious that the only way of preventing such folding and shrinking in vertical direction of the inner package is during the time for filling the package and compression of the filler to bond the inner package to the stiff outer package, and thereafter again releasing this bond, after filling and compression has been executed, and when welding of the lid shall take place.
  • the present invention refers to an arrangement in machines for filling, compression and closing packages of the above mentioned kind.
  • the machine there is within the machine a number of circulatory moulds and arrangements for lowering each package into such a mould before filling the package with material and compressing said material, as well as a number of frames, which are arranged after the package has been lowered into the mould to be lowered down over the mould containing the package.
  • the moulds as well as the frames are formed in such a way that the upper edge of the package above the mould will be clamped between the upper edge of a part of the frame and/or the mould, situated outside of the package, and a part of the frame, introduced into the package.
  • Means for controlling this clamping are so arranged that the clamping is retained during the time for filling and/or compression of the compressed material, and that the frame is not lifted up from the package until after completed compression in order of making possible the closing of the inner package with a lid provided for such purpose, which is welded to the edge of the inner package.
  • FIG. 1 shows a blank for the outer package
  • FIG. 2 shows a perspective of the outer package in its formed state.
  • FIG. 3 shows in a corresponding way a picture of the inner package with indication of the creasing lines, according to which the inner package is shaped
  • FIG. 4 shows a perspective of the mounted inner package.
  • FIG. 5 shows a section through a filled package along with the inner package as well as the lid of the outer package in so called exploaded projection, separated from a re-closing lid pertaining to said parts, and
  • FIG. 6 shows from above a picture of the inner lid with perforations arranged therein for opening the package.
  • FIG. 7 shows a strongly schematical picture of the machine for filling, evacuation and closing of a package, in which the arrangement according to the present invention is introduced.
  • FIGS. 8 11 show different phases in the function of the specific arrangement according to the invention.
  • FIG. 1 thus, the blank of the outer package is shown, which is cut from a rectangular piece 10 of cardboard, preferably double-side plastic covered cardboard.
  • recesses have been made at the places, which are scraffated, viz. symmetrically opposite to each other two pairs of recesses 11' and 11" and 12' and 12''.
  • further recesses 13 and 13" are made at two sides opposite to each other, and recesses 14', 14', 15' and 15" are also made at each comer.
  • the outer package is thereafter ready produced in the state, in which it will be fed in for continuous treatment in the machine according to FIG. 7. This description of the outer package will be required in order that one shall understand, what happens with this package in the machine according to FIG. 7. v
  • the inner package may be made from any deliberate material which gives the required vacuum tightness. It should be mentioned in this connection that with a vacuum packing is meant a way of packing, where the air pressure is below the solution pressurefor oxygen in the oils or fats, often of the type aromatic oils" existing in the packed material. As an example packing of finely ground coffee may be mentioned. This contains rather a lot of aromatic oils, and one knows that the solution pressure for oxygen in these oils is in the order of magnitude of 4 mb, which thus forms a partial pressure, corresponding to an air pressure of 20 mb.
  • Oxygen of higher partial pressure will cause solution and thereafter following oxidation of the aromatic oils, which is called within the food stuff industry, that the coffee has got ransid.” If, however, the partial pressure is lower than the solution pressure, no oxidation can occur. Therefore it has been usual within the range concerned that the packages, before they are vacuum closed, are introduced into a vacuum chamber, from which one will pump out the air to a remaining total pressure in the order of magnitude of about 4 mb. This, anyhow, concerned the above mentioned old type of packages. When removing a package from these vacuum chambers, as mentioned above, the packages are compressed so that they will assume a smaller volume of about percent of the initially existing volume.
  • the interior air pressure raises more than in the proportion 80:100, because an essential part of the contents comprise solid, non-compressible materia.
  • the purpose is that the partial pressure of oxygen shall nevertheless be keptlower than the just mentioned value of the solution pressure or about 4 mb.
  • FIG. 3 shows a cut blank from such a foil material, before it has been re-shaped into an inner package.
  • this blank is cut in the machine, which will be further described in connection with FIG. 7, from a roller of foil material.
  • Dependent upon the resistance of the foil against deformation one may. either without preparatory creasing shape the material in the machine according to FIG. 7 to an inner package according to FIG. 4, or one may in advance crease the blank according to FIG. 3, so that it may easily be re-shaped into the inner package according to FIG. 4.
  • creasing has been made, but it should especially be emphasized that as a rule no creasing is required.
  • the bottom 23 in the inner package thus is separated by means of a creasing line 24 of rounded corners, which is so adapted that the inner package will after its resizing be well adapted to the outer package according to FIG. 2.
  • the inner package is ready shaped and corner welded before it is put down in the outer package. Further indications for the folds to be formed are made by creasing lines. As the folds are mutually equally shaped, it will be sufficient for the purpose existing to describe the fold formation at one of the corners.
  • the four folds 25, 26, 27 and 28 thus are indicated in advance by means of creasing lines.
  • the re-shaping into cup-form one folds inwardly the sides 29 and 30 situated on each side of such a corner, whereby the parts, placed between the creasing lines 25 28 will be bent outwardly. They are thereafter flattened and bent around the formed corner, so that one will obtain a package picture of the type shown in FIG. 4. It is suitable but not absolutely necessary that the inner package is stabilized by welding at the places, marked in FIG. 3 by 31 and 32.
  • the two edge parts 31' and 31" as well as the two edge parts 32 and 32" are thus welded together each per se, whereby it is of value for the continuous treatment of the package that the welding joints do not extend up to the upper edge of the cup-formed inner package. Due to the weakness of the material a well rounded corner formation will be created, possibly under creation of folds, such as indicated at 311 in FIG. 3.
  • FIG. 7 shows as mentioned above, the machine in a very schematical way, because essential parts of the machine according to FIG. 7 have no direct connection with the present invention but one has nevertheless to know the main features of the machine in order of understanding the meaning of the invention.
  • the outer packages are ready produced and fed to the machine in a path 101, so that they will arrive into the turntable 102 at the place 103. They are not yet provided with any inner package, but they are provided with such a one at the place 103, which takes place in the following way.
  • the material of the inner packages is taken off from a roller 104, which is hinged in an shaft device 105. This material is tapeformed, and is brought in the form of the trace 106 through a cutter apparatus 107, in which the blanks of the inner packages according to FIG. 3 are cut and provided with the perhaps existing creasing lines. In this form they are fed into the turntable 102 at the place 108.
  • the outer package is so stiff, that it will not be deformed by the friction at filling on the material to be packed, and by the inner package being clamped onto the inner side of the outer package along the upper edge, deformation of the inner package is also prevented, when the aggregate of outer package, inner package, mould and frame get into the position 120. In this position, as a matter of fact, the material to be packed is filled into the package, after this has been transported over the path 121.
  • the package with the material therein hereafter continues its movement in the turntable 117 past to positions 122 and 123.
  • a piston In the first one of these a piston is pressed down onto the packed material with a rather moderate pressure, so that a pre-compression takes place, driving out an essential part of the air existing between the particles of the material, however without this air being blown out so heavily, that any substantial part of the packed material follows it.
  • the compression In the second position 123 the compression is completed under such pressure that the material is compressed to its final pressure.
  • the piston and the frame are drawn up from the package, whereafter this continues to the position 125, where it is transferred to the next turntable 126 over a path 127.
  • the turntable 126 rotates in the direction of the arrow 128.
  • This turntable is intended to cause the closure of the inner package along with its contents now compressed. This takes place by means of a foil of weldable and tightening material of about the same thickness and preferably of exactly the same kind as the one, from which the proper inner package was made.
  • This material is collected from a roller 129, resting in a shaft construction 130 and drawn forward by a cutter apparatus 131, in which the tape 132 is cut off to adapted pieces 133, which are fed into the position 134.
  • These pieces of foil are kept by means of suction nozzles hovering in such altitude, that they at least in the beginning will not get in contact with the packages, which are brought into the turntable in the position 135.
  • the foil is pressed down onto the upper surface of the packed material by means of a piston, which is so formed that the edges of the foil will be raised upwardly along the edges of the inner package, and in the position 137 the cover foil will be welded together with the upper edge of the inner package along the corners and partly into each side, however so that at the middle of each side a small part is left unwelded in order of making subsequent evacuation possible.
  • the welding tools are elevated and in the position 139 the package is transferred over the path 140 to the next turntable 141, rotating in the direction of the arrow 142, so that the packages are introduced into this turntable in the position 143. It should be observed that the packages were inside of the mould during all of the time from the moment, when they were conbined with said mould into an aggregate in the arrangement 113, so that they have obtained the required support from the mould.
  • the turntable 141 has for its purpose to cause evacuation and final feeling of the package.
  • the package is subjected in the position 144 to a preparatory low vacuum and thereafter in the position 145 for high vacuum.
  • the position 146 the remaining parts of the connection between the cover foil and the inner package are welded together, so that the package will be sealed vacuum tightly, and in the position 147 vacuum is released. Cooling of the welded parts of the package will take place in the position 148, and finally the package, still included in its mould, will be brought out in the position 149 into a path 150, transferring the package along with the mould to an apparatus 151, in which the package is elevated out from the mould.
  • the mould thereafter continues along the path 152 back to the turntable 117 over the path 114 and the apparatus 113 for introducing the package into the mould, whereas the package continues along the path 153 to means for its continued preparation.
  • the continued preparation of the package comprises the following steps, see FIG. and 6:
  • a lid 36 is attached with its grove 37 over the extending edges of the package, whereby the inner package and the outer package are bond together.
  • this attachment takes place in the way, that the package is turned upside down and the edge is dipped into a wax,'pre ferably a plastic wax, whereafter the package is pressed against the lid, so that its edges along with the wax attached thereto is pressed down in the groove 37.
  • the lid should be easily possible to open. For this purpose it is provided with a perforation row all around, comprising slots 38 and between them bridges 39.
  • the lid When opening one has to cut by means of a knife along the perforation row, whereby one will cut away firstly the interior part 40 of the lid, and secondly also cut up a corresponding hole in the closing foil 35 of the inner package.
