Most preferred embodiment first embodiment:

Be explained with reference to the drawings the box-packed bag of first embodiment of the present invention.

Fig. 1-the 5th, the view of the box-packed bag of this first embodiment according to the invention.Figure 1A has showed this first embodiment, fill the box-packed bag of content, and Figure 1B has showed this first embodiment, the box-packed bag that content is drawn out of.Fig. 2 is the perspective illustration that meets the box-packed bag of this first embodiment.In Figure 1A, 1B and 2, this box-packed bag 1 comprises roughly being the box-like carton 2 of cuboid and being included in soft inner bag 3 in the carton 2 as outer container.Content 4 is installed in the inner bag 3 as printing ink.Carton 2 comprises that one is positioned at the swash plate between two rectangular plates, and comprises 4 flat lateral plate 2a, 2b, 2c, 2d and top board 2f and base plate 2e, and a swash plate 2g who is formed between side plate 2a and top board 2f.

One topples over and chews 5 by being contained on the swash plate 2g of carton 2 in the earthing mutually with inner bag 3, and covers with cap 6.Topple over and chew 5 and have the tube 5a that stretches into inner bag 3 and be formed at the end of the tube 5a of a side that is positioned at inner bag 3, be used to the ditch shape passage 5b that this liquid is passed through.Because passage 5b is arranged, even, such as, when the end of the 5a of pipe portion in the inner bag 3 is blocked by inner bag 3, also can content 4 suction be toppled over and chew in 5 through passage 5b.Topple over that to chew 5 projecting heights that exceed carton 2 be to set like this: make to be contained in and topple over the cap of chewing on 56 and be in the zone that extension limited by the extension of side plate 2a and top board 2f.This arrangement can make one in many this box-packed bags on another, and side by side embarks on journey and arow is placed.

Inner bag 3 is bonded on some part of inner surface of box 2 securely.

Promptly, as in shown in Figure 1A-3, what inner bag 3 was bonded at swash plate (topple over and chew adapter plate) 2g, a pair of opposing sideplates 2b, the 2d adjacent with swash plate 2g and the side plate 2a adjacent with swash plate 2g lower edge is on the whole inside face basically, and what inner bag 3 can be bonded at swash plate 2g and side plate 2a by point with lining cement is on the whole inner surface basically.Inner bag 3 be bonded to not adjacent with swash plate 2g and with its away from 4 angles of side plate 2c on.Fig. 2 has showed the adhesion zone 9 of inner bag.Fig. 3 showed carton blank half-blank 2 '.In Fig. 3, the shaded area of making fork of inner bag adhesion zone 9 is to throw off district 9a, and the parallel lines shaded area of inner bag adhesion zone 9 then is to throw off district 9b.

What so just inner bag is bonded at swash plate 2g, pair of side plates 2b, 2d and the side plate 2a below swash plate 2g is on the whole inside face basically, and partly is bonded on the inside face of side plate 2c, inner bag can be fixed in the carton 2 firmly whereby.With throwing off on the bonding inside face that inner bag 3 is bonded at carton 2.As a result, when content was discharged and reduce, inner bag 3 was with regard to shrinkage and be easy to and carton 2 breaks away from.

With inner bag 3 in being located at inner bag adhesion zone 9 spot gluings on four jiaos of side plate 2c on side plate 2c.When chewing 5 when emitting content 4 through toppling over, inner bag is out of shape gradually, chews 5 and moves to toppling over.At this moment, inner bag 3 at first with away from toppling over is chewed 5 side plate 2c and is thrown off, this spot gluing of inner bag 3 and side plate 2c then help making inner bag 3 easily with side plate 2c disengagements.As shown in Figure 2, the inner bag adhesion zone 9 on the side plate 2c can be square or rectangle.

Explain the as above constructive method of the box-packed bag 1 of structure then.At first, the regulation shape cardboard that punching goes out as shown in Figure 3 can be assembled into this box with preparation, have the carton blank half-blank 2 of plate 2a '-2h ' '.Inner bag adhesion zone 9 is formed at plate 2a ', 2b ', 2c ', 2d ' is on the inside face of 2g ' (they will become side plate 2a, 2b, 2c, 2d and swash plate 2g).Form carton blank half-blank 2 ' in, such as shown in Figure 4, sheet film is folded into tubulose, the sealing of turning back in the end then, the formation hermetic unit 16 of turning back.The film of rolling well is cut into tubular film 3 ' (its T﹠B end will be sealed to inner bag in subsequent step) of Len req.

Then with adhesives as the latex class, as, the adhesives of vinyl acetate family, acrylic copolymer family, vinyl acetate-acrylic copolymer family, modification ester acrylate copolymer family etc. be coated in be formed at carton blank half-blank 2 ' being essentially on the inner bag adhesion zone 9 on the whole inside face of plate 2a ', 2b ', 2d ' and 2g '.With this lining cement be coated in partly be formed at carton blank 2 ' side plate 2c ' on inner bag adhesion zone 9 on and on the 2h ' of lining cement limit.When 2 ' time of assembling carton half-blank, with lining cement limit 2i ' invagination, then with hot-melt adhesive, as vinyl-vinyl acetate copolymer family, the lining cement of polyvinylacetate family, SB family, styrene-isobutylene copolymers, polyisobutene co-polymer family, polyester family etc. also is coated on the 2i ' of lining cement limit.Latex class adhesives also is coated in the back side of lining cement limit 2h '.

Then, as illustrated in fig. 3 with adhesives with tubular film 3 ' be bonded at carton blank half-blank 2 ' plate 2a ', 2d ', 2g ' on.In 2 ' time of assembling carton half-blank, tubular film 3 ' place make the fold back hermetic unit lean against that side plate 2c goes up and with topple over chew 5 relative.Then side plate 2b ', 2c ' are folded in tubular film 3 ' on, be sealed to tube again.With plate 2b ', 2c ' and lining cement limit and tubular film 3 ' bonding, adhesive sheet 2b ' then.Before assembling, just formed flat box-packed bag like this.

Then that this is flat box-packed bag 1 transports assembling procedure position and filling operation position to, is assembled into cuboid then there and finishes assembling.Then, the dress on the punching Output Tray blank half-blank 27 is toppled over the position 15 (Fig. 3) of chewing, and refills to topple over and chews 5.Then, with tubular film 3 ' upper end sealing.

This sealing process carries out (in Fig. 5 A-5D, for ease of understanding, carton is simplified displaying) by shown in Fig. 5 A-5D.That is, as shown in Fig. 5 A, in cuboid, the tubular film 3 of opening ' the end as shown in Fig. 5 B closure, this end is laterally sealed to form first sealing 10 then.Then, as shown in Fig. 5 C, first sealing 10 is flattened to form leg-of-mutton flanging 11 in both sides.The bottom side of this triangular flaps is sealed to form second sealing 12.Then shown in Fig. 5 D with this triangular flaps invagination, whereby because tubular film 3 ' this end sealed and with tubular film 3 ' assemble.Because second sealing 12 on the bottom side of triangular flaps 11 just makes inner bag 3 not have and enters the content that triangular flaps is stored in the there that the result can not keep a large amount of contents.Second sealing 12 has the enhancing effect, and inner bag can be remained cuboid substantially.When extracting content out, can make inner bag with good shape bulk deformation.

At tubular film 3 ' after the assembling with its upper end sealing, just assemble carton blank half-blank 2 ' the top.

Then, with sealed tubular film 3 ' the identical method in upper end with its lower end sealing, assemble subsequently carton half-blank 2 ' the end.Then be assembled in this box-packed bag 1 that has inner bag in the carton 2.This technology can box-packed bag formation technology routinely be carried out, and constitution equipment etc. then will not illustrate.With content, be contained in the box-packed bag 1 as printing ink or other article, and the state of box-packed bag is just shown in Figure 1A at last.

Use shown in Figure 1A and 1B this box-packed bag of content 4 is housed the time, chew this box-packed packedly at machine with direction toppling over down, on printer or other machine, then this is toppled over the joint (not shown) of chewing and connects with the aspirator that belongs to this machine.Content 4 is sucked and chews 5 dischargings through toppling over.At this moment, the inner bag adhesion zone 9 on the side plate 2c of inner bag 3 beginnings and spot gluing is thrown off, and then throws off with pair of opposing sideplates 2b, 2d.When pump contents thing 4, inner bag 3 throw off part as shown in long and two-short dash line 21a, 21b among Figure 1B, deforming, chew 5 and move to toppling over then, content 4 can be stablized the unmodified amount and discharges whereby, and need not make in the air admission inner bag 3.The part of throwing off of last inner bag 3 is inhaled into and is fixed on the carton inside face, and is in all the other half the not disengagement part of inner bag 3 basically, thereby almost entire contents is discharged.

Below, the adhesion strength that explanation can be thrown off part 9b and can not be thrown off part 9a.

It is roughly as follows with the bind strength that can not throw off part 9a to throw off part 9b:

Bind strength (the wide required power (gf) of sample disengagement of 15mm that makes when at room temperature standing tensile test is:

The intensity that can throw off part 9b when beginning to throw off:

About 470gf

The bind strength that can throw off part 9b: about 210gf.

The bind strength that can not throw off part 9a is preferably than this intensity height that can throw off part 9b.

As mentioned above, according to this embodiment, content 4 chews 5 when extracting out through toppling over, and inner bag 3 is at first thrown off with the inner bag adhesion zone 9 of its spot gluing, throws off with the inside face of pair of side plates 2b, 2d, and progressively is out of shape and shifts to topple over and chew 5.Then, the disengagement of inner bag 3 partly is inhaled into it and does not throw off part, can basically entire contents 4 be chewed 5 extractions through toppling over whereby.

When content 4 reduced, inner bag 3 was thrown off with the inside face of carton 2 gradually, and inner bag 3 is thrown off egregiously, and contacts tightly with throwing off part, thus the not discharging of limiting content thing 4.

Topple over 5 centers that are located substantially on swash plate 2g of chewing.Fold back hermetic unit 16 on the inner bag 3 is positioned at it and leans on position on the side plate 2c, and chews 5 relatively with toppling over, and promptly is located substantially on the central authorities of side plate 2c.The content 4 that this layout can make inner bag 3 is out of shape owing to extracting content 4 out at inner bag 3, and shifts to topple over to be driven to when chewing to topple over and chew 5 and do not interrupt.

That is inner bag 3, this distortion when the fold back hermetic unit 16 harder than its remainder trends towards stoping inner bag 3 distortion.Thereby, lean against at fold back hermetic unit 16, such as, under the situation of the side plate 2b adjacent with swash plate (topple over and chew adapter plate) 2g, fold back hermetic unit 16 just stops because inner bag 3 may be with respect to toppling over the distortion of chewing 5 the caused inner bag 3 of horizontal assymmetrical deformation.

According to the present invention,,, the content of inner bag 3 can be sent to reposefully whereby to topple over and chew 5 and do not have an asymmetric distortion so inner bag 3 can be toppled over and be chewed 5 and be out of shape symmetrically as central cross because fold back hermetic unit 16 is to chew 5 and place facing to toppling over.

Explain another embodiment of the present invention with reference to Fig. 6 below.Except that the shape of inner bag adhesion zone was different with this shape in the embodiment shown in Figure 1A-5D, the embodiment shown in Fig. 6 was identical with the embodiment shown in Figure 1A-5D basically.

As shown in Figure 6, carton blank 2 ' plate 2b ', inner bag adhesion zone 9 on the 2d ' (they will become side plate 2b, 2d) has limitrophe depressed portions 23a and protrusion 23b, and at plate 2b ', the border of the inner bag adhesion zone 9 on the 2d ' is recessed and epirelief.

Plate 2b ', the recessed and upper convex portion 23a of the inner bag adhesion zone 9 on the 2d ' and 23b are preferably chewing 5 farthest parts and are forming from toppling over.When chewing 5 when extracting contents 4 out through toppling over, inner bag begins and the chewing 5 farthest parts and throw off from toppling over of pair of side plates 2b, 2d, and is chewing recessed and upper convex portion 23a and the 23b that 5 farthest the parts of inner bag adhesion zone 9 form and then can make inner bag begin reposefully to free from toppling over.

In above-mentioned each embodiment, topple over and chew 5 the cylindrical shape part 5a that stretches in the inner bag 3 is arranged, chew 5 and be not limited thereto kind of a structure but topple over.Topple over that to chew 5 can be not have common the toppling over of cylindrical shape position 5a to chew.Can be provided with in the bottom of inner bag 3 suitable channel part (for example other shape such as rod like parts or H tee section) when the thrown off part of inner bag 3 is inhaled into it can not the tear-away portion timesharing, guarantee the passage that content passes through.

When taking out content 4, chew 5 and down box-packed bag 1 situation about being contained on the machine was introduced to topple over, but this state not substantial.According to machine, available supine, or 5 mounting boxs pack 1 is chewed in horizontal toppling over.By with supine topple over chew 5 box-packed bag 1 be contained on the machine, can prevent that content from chewing 5 seepages from toppling over.

As mentioned above, according to the present invention, before content 4 was drawn out of, inner bag 3 was securely fixed on the inboard of carton 2, and when extracting content 4 out, inner bag 3 can be thrown off with the inboard of carton 2, and the generation distortion is also shifted to topple over and chewed 5.The deformable segment of inner bag 3 is inhaled into its indeformable part, whereby can through topple over chew 5 will be basically entire contents 4 extract out and do not interrupt.Inner bag 3 is thrown off with the inside face of carton 2 gradually, makes the thrown off part of inner bag 3 not throw off the part closed contact with it, thus limiting content thing not.Second embodiment

Explain second embodiment of the present invention referring now to accompanying drawing.

Fig. 7 A-10D has showed this second embodiment.The box-packed bag of this second embodiment and first embodiment shown in Figure 1A-3 box-packed bag is basic identical, and same part represents with identical label, so that save detailed narration.

Now, with reference to Fig. 3,4 and Fig. 7 A-10D the constructive method of the box-packed bag of second embodiment is described.At first, such as shown in Figure 3, cardboard is die-cut into required shape, with preparation can be assembled into the carton half-blank 2 of carton 2 '.Carton half-blank 2 ' the inside face of plate 2a ', 2b ', 2c ', 2d ', 2g ' (they will become side plate 2a, 2b, 2c, 2d and the swash plate 2g of carton 2) on inner bag adhesion zone 9 is set.Form half-blank 2 ' in, as illustrated in fig. 4 film is folded into tubulose, then in its end fold back sealing to constitute fold back hermetic unit 16.The film of rolling well is cut into tubular film 3 ' (its T﹠B end will be sealed to form inner bag in the step afterwards) of Len req.

Then with lining cement, as latex class lining cement, such as the lining cement of vinyl acetate family, acrylic copolymer family, vinyl acetate-acrylic copolymer family, acetate modification ester copolymer family etc. be coated in be formed at carton half-blank 2 ' being essentially on the inner bag adhesion zone 9 on the whole inside face of plate 2a ', 2b ', 2d ' and 2g '.With this lining cement be coated in be formed at partly carton half-blank 2 ' side plate 2c ' and bonding limit 2h ' on inner bag adhesion zone 9 on.When 2 ' time of assembling carton half-blank, with bonding limit 2h ' to invagination, then with hot-melt adhesive, also be coated on the bonding limit 2h ' as the adhesives of vinyl-vinyl acetate copolymer family, polyvinyl acetate ester copolymer family, polyamine group, polyethylene family, SB family, styrene-isobutylene copolymers family, polyisobutene family, polyester family etc.Also this latex class lining cement is coated on the back side of bonding limit 2h '.

Such as shown in Figure 3 then, by adhesives with tubular film 3 ' be bonded at carton half-blank 2 ' plate 2a ', 2d ', 2g ' on.Tubular film 3 ' arrangement to make and fold back hermetic unit 16 is leaned against on the side plate 2c in 2 ' time of assembling carton half-blank, and with topple over chew 5 relative.Then side plate 2b ', 2c ' are stacked in tubular film 3 ' on be sealed to integral body again.With plate 2b ', 2c ' and adhesives limit and tubular film 3 ' bonding, adhesive sheet 2b ' then.So just formed the preceding flat box-packed bag of assembling.Then, flat box-packed bag 1 is sent to assembling and can station, so that assembling and filling add content.The number of assembling steps of box-packed bag 7A-10D with reference to the accompanying drawings is illustrated.

Such at first as shown in Figure 7A, box-packed bag 1 is assembled into the cuboid that supports by bracing frame 27.At this moment, form opening, and form opening in the both sides of inner bag 3 in the both sides (upper and lower side) of box-packed bag 1.In Fig. 7 A, carton 2 has several side plates 24 on a side opening, and several side plates 25 are arranged on the opposite side opening.

Then, as shown in Fig. 7 B, a pair of bar 28 is descended through the upper shed (side opening) of carton 2.Then this is sent into inner bag 3 so that it is strutted to bar 28.Then, the bar that do not show of another side plate 25 usefulness struts (Fig. 7 c).

Then, as shown in Fig. 7 D, the side opening of a former 29 through carton 2 descended, and send in the inner bag 3.Then, make anode membrane 30, chew installation position 15 (see figure 3)s on the swash plate 2g of carton 2, punching out between former 29 and the formpiston 30 to topple near former 29.

Then, as shown in Fig. 8 A, make an electro-optical tubes 31 chew installation position 15, topple over detection and chew the position and whether be washed near toppling over.Then, as shown in Fig. 8 B, through a side opening clamping is toppled over and to be chewed 5 topple over and chew holding device 32 and fall in the inner bag 3, chew the installation position and move to toppling over again, chew so that install to topple over.

Then, as shown in Fig. 8 C, detect to topple over electro-optical tubes 33 and chew 5 and whether install.As shown in Fig. 8 D, make a ultrasonic generator 34 chew 5 near toppling over.Meanwhile, a super sonic receiver 35 is fallen in the inner bag 3 through a side opening of carton 2.Under this state,, chew 5 ultrasonic sealings on 3 inside faces of the inner bag on the carton 2 so that will topple over by ultrasonic generator 34 output ultrasonic waves.

Then, as shown in Fig. 9 A, fall a pair of bar 41, and it is sent into inner bag 3 make it to open through a side opening of carton 2.Meanwhile, make one group of pawl tool 42, so that each plate 24 on carton 2 opens near carton 2.

Then, as shown in Fig. 9 B, a pair of seal bar 44 is fallen through a side opening of carton 2, it is sent in the inner bag 3, so that its side opening opens again.Meanwhile, make pressure rod 46 shown in Fig. 9 E and a pair of seal bar 47 a side opening, pushed down by the at first pressurized bar 46 of an end opening of a pair of seal bar 44 open inner bags 3 then near inner bag 3.Follow of the end opening sealing of a pair of seal bar 47 with inner bag 3.In an end opening of inner bag 3, form first sealing 10.Fig. 9 E has showed the inner bag of seeing along the direction of the arrow E among Fig. 9 B 3.

Then, as shown in Fig. 9 C, be formed at first sealing in the end opening of inner bag 3 with the cooling of cooling stick (not shown).Then, as shown in Fig. 9 D, the adapter plate 48 that will have pair of side plates 48a places on the upper surface at the first sealing position 10.

Then, a pair of pressurizer plate 49,49 is to the pressurization of this pair of side plates, so that press the triangular flaps on a pair of side that is formed at inner bag 3.So just with the air exhaustion in this triangular flaps 11.

Then, as shown in Figure 10 A, make a pair of seal bar 51, then with the end sealing of seal bar 51, to form second sealing 12 perpendicular to first sealing 10 with triangular flaps 11 near triangular flaps 11.So just the end at inner bag 3 forms a side seals 3a.

Then, as shown in Figure 10 B, a pair of triangular flaps 11 and corresponding plate 24 on inner bag 3 one sides is folding successively, form its shape being arranged in the pressurizer plate 54 above the carton 2 and sending into through under shed (other end opening) between the shaping wedge 53 of inner bag 3 then.

Then, as shown in Figure 10 C like that, all plates on the end 24 is folding, and an end of bonding then carton 2 constitutes its shape placing the pressurizer plate 56 above the carton 2 and send into through other end opening between the powerful wedge 55 of carton 2 again.The sealing that one end of carton 2 is such and form one side closed part.In the case, the one side closed part of this of carton 2 has top board 2f and to top board 2f bevelled, and has dress toppling over thereon and chew 5 swash plate 2g.

Then, as shown in Figure 10 D, pressurizer plate 58 is placed the top of this one side closed part of carton 2.On the other hand, will have the other end opening of shaping dies 57 orders of the swash plate pressurizer surface 57g that adapts top board pressurizer surface 57f with top board 2f and adapt with swash plate 2g, send in the inner bag 3 through the other end opening of inner bag 3 then through carton 2.In the case, shaping dies 57 is being pressed on the one side closed part of carton 2 by a side seal end 3a of first and second hermetic units, 10,12 osed top inner bags 3.This moment, the pressure of shaping dies 57 was produced by pressurizer plate 58.

In this wise a side seal part 3a of inner bag 3 is pressed on this one side closed part of carton 2 by shaping dies 57, one side seal part 3a of inner bag 3 just can be uniform, and stable unmodified meets the shape of one side closed part (corresponding to top board 2f and swash plate 2g) and forms.

Usually only sealing an end of soft inner bag 3 and a side seals branch of soft inner bag 3 is received within is unfavorable for making this side seals 3a to take different shape by the various capacity of inner bag 3 in the carton 2.

Unless inner bag 3 puts with invariable shape, otherwise after the content in inner bag 3 emitted, inner bag 3 had a large amount of residual contents.As a result, inner bag 3 is unfavorable for having had various volumes.

By the present invention, a side seal part 3a of inner bag 3 forms with the shape of shaping dies by one side closed part 2f, the 2g of carton 2, thus a side seal part 3a of inner bag 3 just with good precision formation, and thereby inner bag 3 constant volume is just arranged.On the other hand, inner bag 3 is with rule, and constant stable shape is put, so can make inner bag 3 have only less residual content.Therefore, precision that can be good is contained in a certain amount of content in the inner bag 3.Also have, to topple over and chew 5 and be installed on the swash plate 2g of carton 2, the oblique pressurizer plate 57g of that a part of available shaping dies 57 of then inner bag 3 and the corresponding side seal position 3a of swash plate 2g carton 2 is with uniform, constant stable, and the shape that conforms to the shape of swash plate 2g constitutes.Then, with same method with the in addition end opening sealing of inner bag 3, form other side seal part (having identical structure) then with a side seal position 3a, again with carton 2 hold involution tightly in addition, close part 2e to form other side seal.So just be assembled into the box-packed bag 1 that comprises the carton 2 that inner bag is arranged in it.

These steps can be carried out with the box-packed bag formation technology of routine, and the set forth in detail of constitution equipment has then been omitted.Last box-packed bag 1 content of having packed into, as printing ink, this box-packed bag has the state shown in Figure 1A.

In box-packed when bag shown in Figure 1A and 1B that content 4 is equipped with in use, chew this box-packed packedly at machine with direction toppling over down, on printer or other machine, will topple over then to chew and link to each other with the joint (not shown) of the aspirator that belongs to this machine.Pump contents thing 4 and through topple over chew 5 the discharging.At this moment, inner bag 3 begins and is thrown off by the inner bag adhesion zone on the side plate 2c of spot gluing 9, then throws off with pair of opposing sideplates 2b, 2d again.When pump contents thing 4, the part of throwing off of inner bag 3 is out of shape shown in long and two- short dash line 21a, 2b among Figure 1B like that, and chews 5 and move to toppling over, and content 4 can be discharged whereby and does not make air admission inner bag 3.At last, the part of throwing off of inner bag 3 is inhaled on the inwall that is fixed in carton 2, and is on all the other half the not disengagement part of inner bag 3 basically, thereby almost entire contents all is discharged from.

Then, the adhesion strength that explanation can be thrown off part 9b and can not be thrown off part 9a.

It is as follows basically with the bind strength that can not throw off part 9a to throw off part 9b.

Bind strength (desiring to make the wide sample of 15mm-to throw off required power (gf) when being used as the tensile test under the room temperature) is:

The intensity that when beginning to throw off, can throw off part 9b:

It is about 470,

The bind strength that can throw off part: about 210gf.

Best is that the bind strength that can not throw off part 9a is higher than the bind strength that can throw off part.

As mentioned above, according to the present embodiment, one side seal part 3a of inner bag 3 is by the shape formation of the formation mould that top board pressurizer surface 57f and swash plate pressurizer surface 57g is arranged by this one side closed part that is limited by swash plate 2g and top board 2f, a side seal part 3a who whereby can high precision constitutes inner bag 3, thereby inner bag 3 can have constant volume.Because the second sealing position 12 is located on the proximal end of perpendicular triangular flaps 11, is limited in the triangular flaps 11 so prevented content, it is residual that the result does not have more content.There is humidification at the second sealing position 12, can make inner bag 3 keep being essentially cuboid.When content is extracted out, the warpage that inner bag usually can be good.

In the above-described embodiment, topple over and chew 5 the cylindrical part 5a that stretches into inner bag 3 is arranged, chew 5 and be not limited to this structure but topple over.Topple over that to chew 5 can be that common toppling over chewed, and do not have this cylindrical part 5a.The thrown off part that to work as inner bag be inhaled into its not the tear-away portion timesharing guarantee that it is possible that content passes through at the suitable channel part of passage (as, other shape part in stick-like or H cross section) is located at inner bag 3 the end.

When taking out content 4, explained with ventricumbent topple over chew box-packed bag 1 situation about being contained on the machine, but this state is not necessarily.According to machine, box-packed bag 1 topple over chew 5 can be up or horizontal suitably installation.Chew 5 with box-packed packed on machine with toppling over up, can prevent that then content from chewing 5 seepage from toppling over.

Also have, inner bag 3 is suitable for invariable shape, whereby after contents discharged, has only seldom residual.

According to the present invention, available formation mould 57, the shape that is limited by the top board 2f and the swash plate 2g of carton 2 constitutes a side seal position of inner bag 3, makes inner bag 3 have the substantially invariable volume of high precision whereby.

Inner bag 3 can perseverance stably be put.When extracting content 4 out, inner bag is usually with good warpage, and has only less content residual.The 3rd embodiment

The 3rd embodiment of the present invention then is described with reference to the accompanying drawings.

Figure 11 A-13 has showed the box-packed bag that meets third embodiment of the invention.Figure 11 A has showed the box-packed bag under the situation that content is housed, and Figure 11 B has showed the box-packed bag under the situation that content is drawn out of.Figure 12 is the perspective schematic view of this box-packed bag.In Figure 11 A, 11B and 12, this box-packed bag 1 comprises that one provides outer container, is essentially the box-like carton of cuboid 2 and a soft inner bag 3 that is received within this outer container.Soft inner bag 3 fills liquid content 4, as printing ink or other article.Carton 2 has the swash plate between two adjacent rectangular plates, and four flat side plate 2a, 2b, 2c, 2d, top board and base plate 2e, 2f and be formed at swash plate 2g between side plate 2f, 2a.

Toppling over of communicating with inner bag 3 is housed on the swash plate 2g of carton 2 chews 5, and topple over and chew 5 and covered by cap 6.Topple over and chew 5 and have once swash plate 2g and inner bag 3 and stretch into the tube 5a of inner bag 3, and be formed in this end of tube 5a on inner bag 3 these sides, be used to the groove shape passage 5b that this liquid is passed through.Because passage 5b,, also can topple over content 4 through passage 5b suction and chew 5 even when the tube 5a in inner bag 3 is stopped up by inner bag 3.Topple over and chew 5 projecting heights that exceed carton 2 and will set to such an extent that make and cover in the zone that extension limited of toppling over extension that the cap of chewing on 56 is in side plate 2a and top board 2f.This structure can make one in many box-packed bags in rows and columns place on another and side by side.

Inner bag 3 is bonded on the part inside face of carton 2 securely.

That is, as shown in the 11A-13, inner bag 3 is bonded at swash plate (topple over and chew adapter plate) 2g, pair of opposing sideplates 2b, the 2d adjacent with swash plate 2g and with basic all inside faces of swash plate 2g base adjacent side plates 2a on.This inner bag 3 can be with the lining cement spot gluing on the whole inside face of being essentially of swash plate 2g and side plate 2a.

As shown in Figure 12 and Figure 13, inner bag 3 also is bonded to removing on the zone of strip tape 18 of toward each other a pair of and adjacent with swash plate 2g side plate 2b, 2d.Strip tape 18 on pair of side plates 2b, 2d is to topple in connection basically to chew 5 and the zone that forms, the middle part from toppling over the straight line 21 (seeing Figure 11 A and 11B) of chewing 5 distal end 20 of carton 2, and is basically perpendicular to straight line 21.The strip tape 18 that forms like this on pair of side plates 2b, 2d as described below, when the inside face of inner bag 3 and carton 2 breaks away from, can make that farthest the end 20 of inner bag 3 on pair of side plates 2b, 2d begins to throw off, and finish this disengagement.

Inner bag 3 also partly is bonded at not adjacent with swash plate 2g, and with it away from side plate in side plate 2c go up (with its 4 angle adhesions mutually).Figure 12 has showed inner bag adhesion zone 9.Figure 13 show the carton half-blank 2 that constitutes carton 2 '.In Figure 12 and 13, this is on side plate 2b, the 2d, at strip tape 18 upsides, and from toppling over to chew 5 nearer part inner bag adhesion zone be to throw off district 9a.And remainder is to throw off district 9b.Inner bag adhesion zone on side plate 2c is to throw off district 9b.

As mentioned above, inner bag 3 is bonded on the whole inside face of being essentially of the following side plate 2a of whole inside faces of swash plate 2g and swash plate 2g, pair of side plates 2b except that strip tape 18, on the inside face of 2d and on the part inside face of side plate 2c, whereby inner bag 3 is securely fixed in the inboard of carton 2.With lining cement that inner bag 3 is releasably bonding with carton.Therefore, when content 4 reduces, inner bag 3 and carton 2 are thrown off, and withdraw from.

When chewing 5 when discharging contents 4 through toppling over, inner bag 3 is out of shape gradually and chews 5 and move to toppling over.At this moment, inner bag 3 at first begins to throw off with side plate 2c.Inner bag 3 makes it be easy to throw off with side plate 2c with the spot gluing of side plate 2c.Inner bag adhesion zone 9 on the inside face of inner bag 3 and side plate 2c can be square or rectangle.

The method of the box-packed bag 1 that constitutes said structure is described then.At first, by regulation shape die cut cardboard shown in Figure 13, with preparation can be assembled into the carton blank half-blank 2 of carton '.Inner bag adhesion zone 9 be formed at carton half-blank 2 ' plate 2a ', 2b ', 2c ', 2d ', 2g ' (they will become side plate 2a, 2b, 2c, 2d and swash plate 2g) on.Form carton half-blank 2 ' in, as shown in Figure 4, a film is folded into tubulose, again in the sealing of end fold back to form fold back hermetic unit 16.The film of rolling well is cut into tubular film 3 ' (its T﹠B end will be sealed to form inner bag in the step in the back) of Len req.

Then with lining cement, as latex class lining cement, such as, the lining cement of vinyl acetate family, acrylic copolymer family, vinyl acetate-acrylic copolymer family, modification ester acrylate copolymer family etc. be coated in be formed at carton half-blank 2 ' being essentially on the inner bag adhesion zone 9 on the whole inside face of plate 2a ', 2b ', 2d ' and 2g '.With this lining cement be coated in partly be formed at carton half-blank 2 ' side plate 2c ' on inner bag adhesion zone 9 and the bonding limit on.This bonding limit 2h ' is a part that constitutes the side plate 2b of carton 2, and has and comprise and being formed at can not throwing off district 9a and can throwing off the inner bag bond regions 9 of distinguishing 9b of these strip tape 18 both sides.Also this latex class adhesive agent is coated on the back of the body surface of bonding limit 2h '.

When with carton half-blank 2 ' when being assembled into carton 2, with carton half-blank 2 ' on bonding limit 2i ' to invagination.Also with hot-melt adhesive, be coated on the bonding limit 2h ' as the lining cement of vinyl-vinyl acetate copolymer family, polyvinyl acetate family, polyamine group, polyethylene family, SB family, styrene=isobutylene copolymers family, polyisobutene family, polyester family etc.

Then, as shown in Figure 13, by lining cement with tubular film 3 ' be bonded at carton half-blank 2 ' plate 2a ', 2d ', 2g ' on.Will be with tubular film 3 ' arrange to such an extent that fold back hermetic unit 16 is leaned against on the side plate 2c, make it 2 ' time of assembling carton half-blank with topple over chew 5 relative.Then, with side plate 2b ', 2c ' be folded in tubular film 3 ' on, then be sealed to one.With plate 2b ', 2c ' and bonding limit 2h ' and tubular film 3 ' bonding, then bonding with plate 2b '.So just before assembling, formed flat box-packed bag 1.

Then, the box-packed bag 1 that this is flat is delivered to number of assembling steps station and perfusion step station, is assembled into cuboid then there and finishes assembling.Then, go out carton half-blank 2 ' installation topple over and chew 5 position 15 (Figure 13), install to topple over again and chew 5.Again with tubular film 3 ' upper end sealing.

After the upper end assembling of carton half-blank and sealed tubular film, assembling carton half-blank 2 ' the top.

Then, with tubular film 3 ' the lower end with the same procedure sealing of its upper end of sealing, assemble then carton half-blank 2 ' the end.Then inner bag 3 is received in the box-packed bag 1 of assembling in the carton 2.This technology can be carried out with the technology of the box-packed bag of the formation of routine.At last with content 4, pack in the box-packed bag 1 such as printing ink or other article, so it just has the state shown in Figure 11 A.

When the box-packed bag 11A of content 4 and 11B are equipped with in use, chew 5 with direction toppling over down it is contained in machine, on printer or other machine, and make to topple over and chew 5 and link to each other with the joint (not shown) of the aspirator that belongs to this machine.Pump contents thing 4 also makes it to chew 5 discharges through toppling over.At this moment, inner bag 3 begins from spot gluing, and the inner bag adhesion zone 9 on the side plate 2c is thrown off, and throws off from pair of opposing sideplates 2b, 2d again.When extracting content 4 out, the thrown off part distortion (pressing long and two-short dash line 21a, 21b among Figure 11 B) of inner bag 3, then along connect topple over chew 5 and the straight line 21 of end farthest 20 move, thereby the quantity discharged that content 4 can be constant discharge and not having in the air admission inner bag 3.At last, the part of throwing off of inner bag 3 is inhaled into can not throwing off in the part of all the other half inner bag 3, thereby entire contents all is discharged from basically.

At this moment, on pair of side plates 2b, 2d, the distal end that inner bag begins at paper bag 2 begins to throw off, and the disengagement end of inner bag 3 can be by being essentially at straight line 21 that center forms, and the strip tape 18 that intersects with it is definite definitely, and inner bag 3 is out of shape equably.Thereby amount that can be constant is stably supplied the content 4 in the inner bag 3.

But tear-away portion 9b and bind strength that can not tear-away portion 9a will be described then.

But tear-away portion 9b and bind strength that can not tear-away portion 9a are roughly as follows.

Bind strength (making the wide sample of 15mm throw off required power gf when at room temperature making tensile test)) is

But the intensity of tear-away portion 9b when beginning to throw off: about 470gf

But the bind strength of tear-away portion 9b: about 270gf.

But can not have the bind strength that is higher than tear-away portion 9b by tear-away portion 9a.

As mentioned above, according to the present embodiment, when chewing 5 when extracting contents 4 out through toppling over, inner bag 3 at first begin with and the inner bag adhesion zone 9 of its spot gluing throw off, throw off with the inside face of pair of side plates 2b, 2d again, and distortion and chew 5 and move gradually to toppling over.The disengagement of inner bag 3 then partly is inhaled into it can not throw off in the part, whereby, can will be basically entire contents 4 chew 5 extractions through toppling over.At this moment, on pair of side plates 2b, 2d, the disengagement of inner bag 3 terminates in strip tape 18, and inner bag is out of shape equably, thereby can stablize the content 4 in the unmodified amount conveying inner bag 3.

The fold back hermetic unit 16 that forms on the inner bag 3 lean against on the side plate 2c and with topple over chew 5 relative.Therefore, when extracting content 4 out, inner bag 3 distortion are also chewed 5 and are moved to toppling over, and the content in the inner bag 3 are discharged into to topple over whereby to chew 5 and do not interrupt.

That is, hard than inner bag 3 remainders inner bag fold back hermetic unit 16 is tending towards hindering the distortion of inner bag when distortion.Therefore, lean against at fold back hermetic unit 16, such as, under the situation of the side plate 2b adjacent with swash plate 2g (topple over and chew adapter plate), fold back hermetic unit 16 has hindered inner bag 3 distortion, and consequently inner bag 3 is chewed 5 and is done horizontal asymmetric distortion with respect to toppling over.

According to the present invention, because fold back hermetic unit 16 is to chew 5 settings facing to toppling over, so inner bag 3 can lead to the content in the inner bag 34 to topple over and chew 5, and not have asymmetric distortion whereby reposefully with respect to chew the distortion of 5 lateral symmetry ground as toppling over of center.

In the above-described embodiment, topple over and chew 5 and have the cylindrical part 5a that stretches in the inner bag 3, be not limited to this structure but topple over to chew.Topple over that to chew 5 can be not have common the toppling over of cylindrical part 5a to chew.To be inhaled into its suitable channel part that can not the tear-away portion timesharing can guarantee that content passes through (as, other part of stick-like or H tee section) in the thrown off part of inner bag 3, to be contained in also be possible at the end of inner bag 3.

When taking out content 4, explained with ventricumbent topple over chew 5 with box-packed packed situation on machine, but this state is not necessarily.Depend on machine, box-packed bag 1 can be with facing up or horizontal toppling over chewed 5 and installed.By supine topple over chew 5 box-packed bag 1 be contained on the machine, can prevent that then content from chewing 5 seepages from toppling over.

As mentioned above, according to the present invention, before extracting content 4 out, inner bag 3 can be securely fixed on the inboard of carton 2, and when extracting content 4 out, inner bag 3 can be thrown off with carton 2 inside faces, thereby chews 5 distortion to toppling over.The thrown off part of inner bag 3 is inhaled into it can not throw off part, thereby can chew 5 and will be essentially whole content 4 and extract out and do not interrupt through toppling over.At this moment, the disengagement of inner bag 3 on pair of side plates 2b, 2d starts from end 20 1 sides farthest and terminates in strip tape 18, the end portion of inner bag 3 is out of shape really, thereby inner bag can be out of shape equably.As a result, can stablize content 4 in the unmodified amount supply inner bag 3.The 4th embodiment

Referring now to description of drawings the 4th embodiment of the present invention.
