Description

The technology of good packaging food, the tool outfit of packing and being used to realize

Present invention relates in general to the packing technique of food.

More particularly, the present invention relates to use current name to be called " sack (big bag) " container packing technique of (the current name of other of this container is called " loose bags (bulk bag) " or FIBC, and the latter is the initialism of flexible bulk mesophase container (Flexible Intermediate Bulk Container)).

These containers (after this being called " loose bags " generally) can be used in the food that transports such as milk powder, dry fruit, fibert etc., and they are for example open in EP-A-1316515, FR-A-2802189, WO-A-89/00957, WO-A-01-17069, WO-A-01/27000, WO-A-03106269 and GB-A-2327072.

Sack is filled with bulk freight usually and is made by flexible laminar material such as synthetic gauze (being polypropylene cloth).In present embodiment, when sack had been folded and has been filled with goods, it adopted the hexahedral shape of almost parallel, for example made it to move on pallet or to transport.For better understanding, and do not do any qualification, the sack of current use can have the leading dimensions of 100-120cm scope, and highly can be 180cm.

Certainly, these sizes cause that sack has sizable weight when filling goods.Based on this reason, sack provides one or more ears of carrying usually at its top, and this makes it possible to hang the sack that empties.

Identical consideration about big bag dimensions causes that sack tends to a certain degree " broadening " when filling article, present the shape away from desirable parallelepiped shape.This is why to have notified the reason that inner reinforcement is provided, so that be limited in the phenomenon that broadens (for example referring to above-mentioned WO-A-01/27000) of sack under the internal product bias voltage.

The propagation of this container causes that himself filling/evacuation modes tends to more and more standard gradually, even what relates to is provided at the sack top and has product filling/evacuation apertures with bottom section and for relevant opened/closed pattern.

Practice by the material manufacture sack with holes such as cloth causes that sack can see through the external agency such as moisture in fact, and can not give the due care that connection with wrapping of piece is avoided these medium influences.For the sake of simplicity, pointed out that sack self constituent material also can be subjected to the negative effect of these external agencys and for example can meet with to tear.Percussion obstacle or the article of for example filling sack when being moved by loader-unloader fall fiercely to produce the article of tearing and not expecting on the ground and leak the risk that causes.

This is why can imagine by changing sack to protect the reason that is included in the article in the sack, makes it become double-walled container.By article receiving vessel or bag are put into sack and can be obtained this result, this sack has continuous wall, can be with article and isolated from outer medium.Carrying out the behavior makes for example produce controlled atmosphere (for example under the vacuum, or for example introduce nitrogen and the part unreactable gas) in protective bag, is used for the present mode of reduced size container thus.

" double-walled " container is well-known in the art, is confirmed US-A-4515692, US-B-6312742, EP-A-0097391, EP-A-1120357 or WO-A-92/16439 by way of example in following patent.Most these double-walled containers mainly are attributable to typology, and it provides by the material manufacture container outer wall of rigidity more or less, and internal protection " bag " is made by flexible material.

Transporting of supposition meets with several difficulties in this sack practice.

At first, the selection article protection bag that will comprise is put into sack and is become and use the antagonism of obvious advantage of relevant some of sack.

For example, being placed on a bag shell (being substantially similar to the sack of being made by flexible material) in the sack makes kinds of goods is loaded into significant difficulties in the sack, this is because when when filling, and falls into inside and when loading when article, need be in sack support pouches to a certain degree.Discharge phase at sack will produce more shortcomings, unless discharge orifice is provided on the lower wall of bag (this is very difficult) sack first closure and can opening to a certain degree in sack discharge orifice position subsequently.

Yet as described above, sack often provides reinforced frame within it, is used for causing and also keeps basic parallelepiped shape when sack fills up article even provide.These tension members in order to make the direct packing article of not obvious obstruction sack, then will become obstacle when bag inserts sack.

Yet the bag or the capsule that are placed in the sack will be intended to receive and support at least the mechanical strees that is produced by material weight in first situation.This factor will be more important when being placed on sack inside when this bag filling article of needs and with it.This behaviour assumption bag self can bear product bias and weight.Except other shortcoming, the manufacturing fully bag shell of holding articles mechanical strees will be used the flexible material that is easy to expensive given thickness.Mention in passing, should expect especially when transporting food, sack tends to be regarded as the consumables, and is not intended to re-use.They have to as far as possible low-cost, and this need be necessary for the bag or the capsule that are intended to put into sack.

Yet; bag is filled article and is put into sack and stand to make vacuum subsequently and/or the unreactable gas of injection protection within it; will be difficult to usually recognize and these possible holes occur at once; these holes can make and vacuum/controlled atmosphere condition failure cause packing the risk that interior article damage fast.Mention in passing, should expect under the situation of the article packing with annual harvesting time (for example fibert), wherein need two continuously basic between the harvesting equate the stage, promptly one-year age keeps article with good condition of storage.

The purpose that the present invention has fully and addresses the above problem satisfactorily.

According to the present invention, owing to following article packing technology obtains this purpose, this article packing technology has and requires in additional claim and as the feature of the part of the application's instruction.

The present invention also relates to the tool outfit packing and make.

Referring now to accompanying drawing, only the present invention is described in the mode of example and with not doing to limit, wherein:

Fig. 1 is the overall perspective view according to packing of the present invention, has excised some parts for clarity; And

Fig. 2 to 6 schematically illustrates the process of making this packing.

Totally say, described herein on the whole by 1 the indication packing comprise two basic components, that is:

-loose bags 2 and

-laminar enclosure 3 is substantially similar to big case or big bag, and it is intended to encase loose bags 2.

Container 2 can be corresponding to any sack of current use.Thereby it can be the sack of in fact commercial available any type when application, for example substantially parallelepiped shape and be of a size of as noted above like that (as just with reference to and therefore the present invention be not intended to be restricted).Container 2 can for example be made by polypropylene cloth.

Parallelepiped shape is not intended to limit the present invention as a reference; It also is effective choice that ear 2a is provided at the upper top place of container 2.Expediently, loose bags 2 can provide tension member (not shown in the drawings, but known type).When filling up article and when this filling has been finished, when the packing 1 that product is arranged within it was moved, transports, deposits and be placed on the discharging gear of container, these tension members were intended to make container 2 to keep its shape basically especially.

For better understanding, after this will suppose-once more by way of example-in Fig. 1, form (for example shell fibert and may stand baking process) by fibert by the article of P indication.

About the embodiment of bag shell 3, can use in technology well known in the art.The section drawing of Fig. 2 illustrates cloth part (for example polypropylene), and it is the container 2 wall portions that are listed in a part of shell 3 walls.In currently preferred embodiment (it is not intended to limit scope of the present invention), shell 3 by four layer by layer laminate materials form, make by the sandwich structure that comprises two-layer nylon cloth 3a and be placed on the aluminium lamination 3b between them basically.So this interlayer of realizing is being intended to subsequently in the face of covering (" coupling ") by the heat-sealable material 3c that is made by polyethylene usually on the sidepiece of package interior, thereby towards loose bags 2 walls.

Fig. 2 point out by technology described herein provide for shell 3 uses the laminated material possibilities, compare with loose bags 2 cloth of about 1 millimeters thick, this shell 3 is thin (its thickness is typically about 250 microns) enough.The thin stack material of the type of describing can low-cost commercial acquisition, and this makes it be used as disposable material.

The section drawing of Fig. 2 allows to learn an importance describing technology here once more, that is, shell 3 is placed on the outside of loose bags 2-and within it the fact not.

When the order of the packing shown in reference Fig. 3 to 6, this aspect can be learned more.

Especially, Fig. 3 shown folding and has been placed on loose bags 2 on the pallet 4, in the middle of preferably the isolation layer (intermediate) 5 made of the material such as cardboard is placed on.

Fig. 3 illustrates the loose bags 2 that hangs over the 2a of ear, makes it be positioned to fill the air discharge port place of storehouse S.The material P that is intended to pack flows out this outlet by freely falling usually.Described fill pattern and the instrument that needs to realize it are known in the art and do not need here to describe in more detail.

Fig. 4 illustrates when the filling of the article P under the S of storehouse has been finished, and by using self substantially shell 3 of bag or capsule, loose bags 2 is encased by shell 3.When filling article P has finished, the in fact preferably behavior that loose bags 2 is put into shell 3, but it is for carrying out the present invention not necessarily.Before the beginning filling step, perhaps alternatively, in filling step carried out, loose bags 2 also can be inserted in the shell 3.This can obtain by mechanism's (not shown) that can support shell 3 is provided, and makes its maintenance be in encasing under the situation of loose bags 2.

No matter adopt which kind of behavior, obtainable net result is the result who describes among Fig. 5, simultaneously loose bags 2 filled with articles P and at exit portion 2b place (it can be to be the closing section of wired, rope or similar component) closure (here also according to known standard).The loose bags 2 of filling article P is placed in the shell 3, and integral body is placed on the pallet 4.

Fig. 6 schematically shows the backend steps of preparing packing 1.This sequence of steps mainly provides the sealing of shell 3, and this by carrying out at the closed bag that forms shell of its outlet side, forms by heat seal each other two of combination edges 30 (better seeing) hermetically usually thus in Fig. 1 transparent view.By in that salable material layer 3 is provided at and carries out this step (referring to Fig. 2) on the above edge with heat on the opposite face.Above heat seal operation obviously can be replaced by the technology (ultrasonic sealing, deposition combination, crimping etc.) of equivalence.

Before jointing edge 30, by using suitable bell jar B (use known standard, these are identical with the standard that is used for smaller szie bag packing), will begin a circulation, it comprises:

-form vacuum (below the barometric pressure) in the shell 3 of article P comprising loose bags 2 and fill, cause most of air therefrom to be removed,

First of-protection unreactable gas (being generally nitrogen) injects,

-carry out the second discharging action by the degree that in shell 3, forms below the barometric pressure, and

-provide the protection unreactable gas injection.

Obviously, the order of description is only corresponding to the preferred embodiment of the embodiment of the invention, and is not intended to limit the essential scope of the embodiment of the invention.Especially, the injection of protection unreactable gas (for example nitrogen) is preferred, but is not the principal element of the scope of the embodiment of the invention.For forming the following degree of barometric pressure (vacuum), obviously, can carry out by one or more steps.

Usually, the level of vacuum that forms quite " strict (hard) " in shell 3 (wherein having loose bags 2 and article P) has proved preferably, and for example coverage area is from the following degree of the barometric pressure of 70 to 80mm mercury column.Representative value is about 76mm mercury column, and it is corresponding to equaling 1/10th the numerical value that normal atmosphere (An) is the 760mm mercury column.

Form the above barometric pressure following (also being that " vacuum " forms) and cause the wall of shell 3 bias voltages (as mentioned above, when adopting condition of high vacuum degree, very consumingly) against loose bags 2, article P within it simultaneously.This packing (referring to Fig. 1) that causes under vacuum so making rigidity that becomes makes sack well keep its parallelepiped shape.This significantly helps the mobile of packing 1 and transports operation.

The description of Fig. 3 to 6 order allows to learn makes packing 1 and the sack of not bigger change filling article P.Can be according to coming execution in step with the model identical of current use basically.

As the containment shell 3 of continuous shell (mainly by shown in aluminium lamination 3b in the illustrative examples guarantee the above continuity and sealing) guarantee that article P electrically isolates from the external agency that is easy to negative effect article P fully.

Also carry out similar protection operation for the material of forming loose bags 2, loose bags 2 protected especially (as article P) is avoided contingent moisture seepage or the accidental risk of infiltrating of liquid.

The packing 1 that this means mentioned kind if necessary can remain on the outside when transporting, at outdoor stacking point or be exposed to the position of external environment condition.

The experience that the applicant obtains is in surprise verified, all relative thin as previously mentioned and cheaply shell also show-when in just describing 1 the scope of packing, using-good seal feature, and mechanical strees resistance.This packs the 1 accidental stress that is easy to produce that falls to the ground and also is suitable for for vibration stress with when arresting.

Do not combine with any specific theory, the applicant has reason and supposes that this surprised effect is the vacuum that forms owing in packing, by the bias voltage lid 3 material effects against loose bags 2 walls very doughtily.Under these situations, carry out cooperative operation, make the wall material of loose bags 2 finally be used as the reinforcement material of shell 3.Further benefit results from as described above, and vacuumizing causes packing 1 rigidity (becoming a kind of solid block basically) that becomes as a whole, is difficult to produce the metaboly that causes that easily shell 3 is torn within it.

Under any circumstance, may the taking place of this tearing (or boring) can be known from the outside at once, is that shell 3 accurately limits the outside faces of packing.Thereby therefore, can recognize at once that packing has lost its sealing characteristics and the article P in it is no longer protected and avoid the external agency influence.This allows for example easily to intervene before it breaks down by the packing that empties article P in it.

Just discharging/the emptying step of the packing of describing 1 is easy.In the practice, can simply carry out emptying step by tearing and remove only a part of shell 3, for example open can mention and tangle loose bags 2 carry ear 2a.At this point, based on the current identical pattern of sack pattern that usually adopts of being used for, can remove shell 3 (, carrying out in the zone of the exhaust outlet of loose bags 2 at least), thereby put down article P if not exclusively.

Obviously, be to be understood that based on the above description and the explanation that only provide by way of example and therefore do not do to limit, can extensively change feature and the embodiment of principle of the present invention, embodiment, and not break away from the scope of the present invention that for example in appended claims, limits.
