Anvil bar 50 and anvil 60 are made of anvil bar 51 and anvil 65 with the long electrolysis of horizontal direction and anvil bar 56 and anvil 66 with the long electrolysis of vertical direction.Anvil bar 51 is connected with the above-below direction midway location of anvil bar 56 from horizontal direction, like this, by anvil bar 51 and anvil bar 56, has formed electrolysis 51a, the 56a of accumbency shape T font.Similarly, anvil 65 is connected with the above-below direction midway location of anvil 66 from horizontal direction.Anvil bar 51 and anvil bar 56, perhaps anvil 65 and anvil 66 can be arranged side by side the anvil bar or the anvil that produce respectively, and be mutually integrated after also can be side by side, perhaps, also can make integratedly.Part with anvil bar 51 and anvil 65 crimping, when not identical with the thickness of the part of anvil bar 56 and anvil 66 crimping, anvil bar 51 and anvil bar 56 are formed as one, anvil 65 and anvil 66 are formed as one, anvil bar 51/ anvil bar 56 and anvil 65/ anvil 66 are made as split.With anvil bar 51/ anvil bar 56 and anvil 65/ anvil 66 separate configuration, with they be made as can crimping structure.In addition, anvil bar 51 and anvil bar 56 are become one, have when sending the ultrasonic oscillator (not shown) of ultrasonic vibration, preferably with anvil 65 and anvil 66 separate configuration, with electrolysis 65a and electrolysis 66a separate configuration.

In addition, shown in the block diagram of Fig. 2 (a) and lateral plan (b), preferably, the electrolysis 65a of anvil 65, have central transversal 64 of traversing its central portion, be formed on transversal 64 both sides of central authorities and be recess 63 than transversal 64 both ends that retreat 62 of central authorities and the groove that is formed between central transversal 64 and the both ends 62, (y direction) seen or section from the side, is " mountain " font of accumbency." than transversal 64 both ends that retreat 62 of central authorities " described here, refer to when anvil bar 51 during with anvil 65 (contacting across being fused thing) close to each other for crimping, transversal 64 crimping of central authorities are fused thing, and both ends 62, keep off the degree that contacts across being fused thing, the electrolysis 51a of anvil bar 51 is left at both ends 62 slightly, is positioned at the position of leaving electrolysis.Because the electrolysis 65a of anvil 65 has central authorities transversal 64, both ends 62 and recess 63, therefore, as described later, the sealing of the end of packaging body 110 (Fig. 1 (a)) is reinforced, and Compressive Strength improves.

Below, go on to say with reference to Fig. 1.Anvil bar 51 and anvil 65, transversal brought together without the 15b of content section and with its sealing (the 1st sealing).On the other hand, anvil bar 56 and anvil 66 will be with 120 sealings (the 2nd sealing), seeing that from the top towards vertical below the U font opening portion with 120 (Fig. 3 (c)) that bends to the U font is closed.Anvil bar 56 and anvil 66 in the slightly outside without the 15b of content section of being brought together, will be with 120 sealings (the 2nd sealing).In addition, also can be heated by resistive other various fusion splicing devices such as fusion splicing devices, electronic heating fusion splicing devices, LASER HEATING fusion splicing devices, replace ultrasonic wave welding device 100.No matter in which kind of fusion splicing devices, all implement with 120 jointly transversal sealings without the 15b of content section (the 1st sealing) of having been brought together with the sealing (the 2nd sealing) of the opening portion closure of U font band 120.The direction of this sealed part, as the sealing direction, be decided to be the 1st sealing direction and the 2nd sealing direction.

Have at distance bundling device 70, with feedway 90 and ultrasonic wave welding device 100 to form without the amount of the predetermined space of the 15b of content section, the i.e. downstream of the amount of a packaging body length, be provided with shutoff device 80.Shutoff device 80 has cutting knife 81.Cutting knife 81 is tabular, there being a side of wanting cut tubular membrane F1 (without the 15b of content section), is provided with sharp keen blade.Cutting knife 81 also with bundling device 70 and ultrasonic wave welding device 100 similarly toward double action.The past double action of cutting knife 81, also with ultrasonic wave welding device 100 and bundling device 70 similarly, perpendicular to the direction of Fig. 1 (a) paper toward double action.Therefore, driven by common actuating device (not shown), so, simple structure, preferred.

In addition, bundling device 70, band feedway 90, ultrasonic wave welding device 100 and shutoff device 80 preferably carry out the so-called motion (shuttle box motion) of paying one's respects to.That is, these devices are used the same speed of speed of transferring toward the below with cylindrical body 15a, toward below move on one side, bring the 15b without content section on one side together, supply with and be with 120 and sealing is cut off simultaneously, after the cut-out, unclamp the 15b without content section, turn back to the position of top.Therefore, if bundling device 70, the band feedway 90, ultrasonic wave welding device 100 and shutoff device 80, be arranged on the stand (not shown) common, that move up and down, then simple structure.

Below, manufacturing packaging body manufacturing installation 1, packaging body 110 of using the present invention's the 1st embodiment shown in Figure 1 is described.Belt type film F is drawn out of from coiled material 21 with predetermined speed, guides and walks arrival shaping plate 11 while applied predetermined tension force ground by deflector roll 22A, 22B.Described " predetermined speed ", refer to make do not produce the speed that wrinkle etc. are extracted belt type film F out on the belt type film F.Described " predetermined tension force ", refer to make do not produce wrinkle etc. on the belt type film F with the tension force of belt type film F welding.

Arrived the belt type film F of shaping plate 11, formed the tubular that has coincidence part at side edge part, by vertical sealing arrangement 13 with the coincidence part welding.Like this, formed vertical hermetically sealed tubular membrane F1., through ozzle 32 content C1 is filled in this tubular membrane F1 from pump 31.Filled the cylindrical body 15a of content C1, sent toward the downstream sidesway by transfer roller 14.A pair of transfer roller 14 local flattens cylindrical body 15a the ground cramping, transports, the cylindrical body 15a that is crushed, passed through the position of transfer roller 14 after, the interior pressure by content C1 is returned to original tubular.

Cylindrical body 15a is spreaded all over the predetermined length cramping discontinuously by a pair of attenuate roller 41, with predetermined space formed do not have content C1 without the 15b of content section.Here said " predetermined length " refers to have the required length without the 15b of content section in end of suitable sealing function in packaging body formation.

Here, also with reference to the partial perspective view of Fig. 3, bringing together, seal and cutting off of packaging body is described.Shown in Fig. 3 (a), in the direction of transversal flat horizontal surface, bring together flat without the 15b of content section with bundling device 70.Shown in Fig. 3 (b), through bringing together, attenuate without the 15b of content section.

On the other hand, shown in the partial perspective view of Fig. 4, in the band feedway 90, be with 120 on one side by roller 93 crampings, keep tool 91 sides (seeing Fig. 4 (a)) Yi Bian be sent to, be cut to predetermined length (seeing Fig. 4 (b)).Described here " predetermined length ", refer to longer than the length along the U font face 94 that keeps tool 91, stretch out in the U font face 94 that keeps tool 91 with 120 length.With 120 length that stretch out in U font face 94, be that the part of stretching out does not hang down and can carry out the 2nd sealing in the part of stretching out, forms the length at the 2nd sealing position 122.This length is not identical because of material, the thickness of band, but to be advisable more than the 1mm and below the 15mm, is preferably in 3mm above and be preferably below the 10mm.Be with 120 after the cut-out, the attraction mouth 92 that is held tool 91 attracts, and forms the U font and is being held (seeing Fig. 4 (c)).In addition, the width of the Width band 120 of maintenance tool 91 is narrow, and keeping tool 91 is not to attract the also width middle position of retainer belt 120, but attracts and maintenance position on the lower.Perhaps also can attract and keep top position.

Therefore, shown in Fig. 3 (c), what form the U font is with 120, surround and clamp without content section 15b ground, overlap brought together without on the 15b of content section." overlapping " described here is to instigate to be with 120 near to or in contact with without the 15b of content section so that brought together be positioned at bottom with 120 U font without the 15b of content section.That is, keep tool 91 to release towards the direction without the 15b of content section.

So anvil bar 50 and anvil 60 will be with 120 and clamp and welding without the 15b of content section.Because anvil bar 51,56 forms as one, anvil 65,66 forms as one (Fig. 1 (c)), so, shown in Fig. 3 (d), can implement simultaneously the 1st sealing and the 2nd sealing.By these sealings, be with 120 and sealed integratedly without the 15b of content section, formed respectively transversal without long band shape the 1st sealing position 121 of the 15b of content section direction and with transversal without long band shape the 2nd sealing position 122 of the direction right angle intersection direction of the 15b of content section.In addition, be with 120 and without the 15b of content section, because by integratedly sealing of the 1st sealing, so the content C1 of cylindrical body 15a and air, moisture etc. are sealed in the circulation of length direction.Like this, cylindrical body 15a becomes the packaging body 110 with leak tightness.In addition, be with 120, be sealed in the cross-directional sealing by the 1st, in addition, be sealed in and the rectangular direction sealing of cross-directional by the 2nd, formed by the cingens closed hoop of these 2 sealings (the 1st sealing, the 2nd sealing), like this, become 2 bags 123,124 towards the tubular membrane F1 direction opening of filling content C1.

The 1st sealing position 121, comprised at long 2 layers banded weld 129-1, the 129-2 of transversal direction without the 15b of content section and be fused that part 129-1,129-2 clip at long 1 layer the band shape of equidirectional weld 128 not.Bundling device 70 (Fig. 1 (a) (b)) separate bring together between the plate 71,72, configuring ultrasonic wave welding device 100 (Fig. 1 (c)), in this ultrasonic wave welding device 100, the width of the 2nd sealing direction at the 1st sealing position 121 is limited, so that do not produce mechanical interference.Form like this 1st sealing: under this restriction, the width of the 2nd of weld 128 the sealing direction does not preferably have the following Design freedom of 3mm, more preferably below the 1.5mm, and 0.75mm more preferably.

If the width of the 2nd of weld 128 the sealing direction has not surpassed 3mm, then can not be parallel with the 1st sealing direction and point-blank will be not weld 128 cut off, cutting portion can become the shape of wave, so can't help choosing.If this width is above 1.5mm and below 3mm, during with high-speed operation packaging body manufacturing installation 1, even the vibration frequency of packaging body 110 is high, because this vibration seals the direction almost parallel with the 1st, so cutting portion does not become the shape of wave.This width is 1.5mm when following, can process beautiful cutting portion.When this width is 0.75mm, can process more beautiful cutting portion (also identical in the following embodiment).

Here, keeping tool 91 is not the position of the width central authorities of retainer belt 120, but on the lower position retainer belt 120, because anvil bar 51 and anvil 65 will be with central authorities' sealings of 120 width, so, keep tool 91 and anvil bar 51 or anvil 65 not to disturb.That is, anvil bar 51 and anvil 65 mechanically do not arrange at above-below direction intrusively with keeping tool 91 with staggering.Clamp with anvil bar 50 and anvil 60 and to be with at 120 o'clock, keep tool 91 to stop from the attraction that attracts mouthfuls 92, from without retreating around the 15b of content section.In addition, the 2nd sealing that the 1st sealing that anvil bar 61 and anvil 65 carry out and anvil bar 56 and anvil 66 carry out can not carried out simultaneously yet, and is carried out respectively, can carry out first the 1st sealing, can carry out first the 2nd sealing yet.

In addition, the crimping of anvil bar 51 and anvil 65 is to clip under the state without the 15b of content section of being brought together with 120 with surrounding, with 120 and quilt brought together without together crimping of the 15b of content section.On the other hand, anvil bar 56 and anvil 66, a crimping band 120.Therefore, the object of anvil bar 51 and anvil 65 crimping is thick.For this reason, make the electrolysis 66a of anvil 66, stretch out towards anvil bar 56 sides than the electrolysis 65a of anvil 65.Because the electrolysis 66a of anvil 66 stretches out, so, be fused thing (being with 120) but crimping is thinner, in addition, can prevent excessive to the thicker extruding that is fused thing (brought together without the 15b of content section with 120), prevent that compressive resistance from carrying out crimping with reducing.In addition, the adjusting of electrolysis position also can be carried out with the electrolysis 51a of anvil bar 51 and the electrolysis 56a of anvil 56.

Shown in Fig. 2 (b) lateral plan (c), on the electrolysis 65a of anvil 65, when having formed central transversal 64, both ends 62 and recess 63, with transversal 64 crimping bands 120 of central authorities with without the 15b of content section, at this moment, melting fused mass S accumulate in the recess 63, this fused mass S is attached to the both sides that are crimped hermetic unit.Therefore, be crimped the part of sealing, by adhering to of both sides the part of fused mass S and thickening strengthen, compressive resistance improves.In addition, be crimped the part of sealing, because of the correspondingly attenuation of outflow of fused mass S, after in the shutoff device 80, easily be cut off.

As Fig. 3 (e) (f) shown in, cylindrical body 15a, after having implemented the 1st sealing and the 2nd and seal by ultrasonic wave welding device 100 (Fig. 1 (c)), by shutoff device 80 (Fig. 1 (c)), band shape weld 128 not at the 1st sealing position 121 does not cut off it on weld 128 ground point-blank along this.At this moment, the 2nd sealing position 122 also by cutting off the not line of weld 128, is cut to up and down two parts simultaneously.After the cut-out, become the 2nd sealing position 122-1 of upside, the 2nd sealing position 122-2 of downside.In addition, be with 120, by the weld 129-1 at the 1st sealing position 121 that is formed by the 1st sealing in cross-directional sealing ,-2 and by the 2nd sealing position 122-1 ,-2 that forms in the 2nd sealing with the crisscross sealing of cross-directional, become by the closed ring state of 2 sealings (the 1st seal, the 2nd seal) encirclement.After cylindrical body 15a such as aforementioned being cut off, become a packaging body 110, (Fig. 1 (a)) transports from packaging body manufacturing installation 1, for example, through boiling, the necessary furnace run such as distillation, as product export.In addition, owing to being cut off at 2 bags 123,124 the end with 120, so, become respectively the bag (closed ring state) (seeing Fig. 6) of the end 116 that surrounds packaging body 110.In addition, the furnace run of packaging body 110 (Fig. 1 (a)), temperature with 60～120 ℃ of degree is carried out, through this furnace run, the Bag-shaped belt 120 that surrounds the end 116 of packaging body 110 produces thermal contraction, owing to be with 120 to have aforesaid heat-shrinkable, so, with 120 and the degree of connecting airtight of tubular membrane F1 increase, the leak tightness of end 116 improves.

As mentioned above, the packaging body manufacturing installation 1 of the 1st embodiment according to the present invention, the hermetic unit of the end of packaging body 110 is surrounded by the bag with 120.Because the hermetic unit bedding bag surrounds, so, for example because of boiling so that content C1 expands and tubular membrane F1 is such when causing interior pressure to act on the packaging body 110 because of content C1 when shrinking, the distortion of hermetic unit is by with 120 bag inhibition.Therefore, act on the stress reduction on the tubular membrane F1 of hermetic unit, can obtain the packaging body 110 that hermetic unit is not easy to damage.That is, compressive resistance improves.In addition, in band and the packaging body (not shown) before that seals integratedly of tubular membrane, during the cooking, boiled in the packaging body of heating, usually be with curlingly, outward appearance is bad.And as present embodiment being with 120 to form bag-shapedly, then can prevent curling.

In addition, be with 120, have heat-shrinkable, the percent thermal shrinkage of its length direction is 10% to 35%.Because with the percent thermal shrinkage of 120 length direction, greater than the percent thermal shrinkage of Width, so, packaging body 100 bring the end together, can be with 120 conscientiously to fasten, can significantly reduce the pore incidence at the hermetic unit of end.Since supply with 120 reverse little, so, band feedway 90 (Fig. 1, Fig. 4) can be effectively with 120 supply.

Package according to the present system manufacturing apparatus 1, the quilt of tubular membrane F1 bring together without the 15b of content section, and be with 120 sealedly together,, formed by with 120 hermetic units that clip without the 15b of content section sealed, like this, manufacture packaging body 110.The cut hermetic unit of packaging body 110 is end 116, aforementioned hot is inotropic is with 120 to clamp by having, be with 120, by the 1st the sealing position 129-1 and the 2nd the sealing position 122-1 form bag-shaped, like this, even the surface of the tubular membrane F1 that is brought together has concavo-convex, this convex-concave surface and also connecting airtight equably with 120 surface, and, owing to having replenished the thickness of the tubular membrane F1 of sealed part, so, can obtain having the packaging body 110 that leak tightness and end are not easy to produce pore.

Its effect is, because weld 128 cuts off, so, be attached to the power on the cutoff tool, little during than cut-out weld 129, so, can cut off effectively.In addition, also cutoff tool can be prolonged until the life-span of changing.Cutoff tool can use rotating knife, single face cutter, two-edged knife, chopper etc.

Below, with reference to diagram of circuit, Fig. 1 and Fig. 3 of Fig. 5, the manufacture method of the packaging body 110 of the present invention's the 2nd embodiment is described.Here, be the packaging body manufacturing installation 1 that uses the present invention's the 1st embodiment, but be not limited to this packaging body manufacturing installation 1, also can make packaging body with any manufacturing installation.

At first, with shaping plate 11 grades the side edge part of belt type film F is overlapped, belt type film F is formed tubular, formed tubular membrane F1 (step St1) (tubular membrane formation operation).The vertical sealing of the coincidence part of tubular membrane F1 side edge part (vertical sealing process), like this, be configured as the cylindrical body 15a (step St2) (cylindrical body forming process) of vertical sealing.Then, from being inserted in the ozzle 32 in the cylindrical body, content C1 is filled into (step St3) (filling work procedure) in the cylindrical body.

The cylindrical body 15a attenuate of having filled behind the content C1, thus with predetermined space, form flatly have predetermined length do not have content without the 15b of content section (step St4) (attenuate operation).Along the direction of flat face, bring together established without the 15b of content section (step St5) (bringing operation together).Supply is with 120, with 120 overlap bring together and attenuated without upper (step St6) (the tape member supply operation) of the 15b of content section.Be with 120 to be the U font, make the bottomland that is positioned at U font band without the 15b of content section be with 120 overlapping.Be with 120 to have heat-shrinkable, the percent thermal shrinkage of its length direction is 10% to 35%.The percent thermal shrinkage of the length direction with 120 is larger than the percent thermal shrinkage of Width (with the rectangular direction of length direction).

At the above-below direction central portion without the 15b of content section, will without the 15b of content section with being with 120 sealings (the 1st sealing), form the 1st sealing position 121 (step St7) (the 1st sealing process) in cross-directional.By sealing, be with 120 and become one without the 15b of content section, in addition, the content C1 of tubular membrane F1 and air, moisture are sealed in the circulation of length direction.Therefore, obtain the high packaging body of leak tightness 110.

This packaging body manufacturing installation 101 is compared with the packaging body manufacturing installation 1 (Fig. 1) of the 1st embodiment, and with the maintenance tool 191 of feedway 190, anvil bar 150 and anvil 160 differences of ultrasonic wave welding device 200, remaining structure is all identical.Below, difference mainly is described.In addition, namely be with 220 (Fig. 8 (c)) with the tape member that feedway 190 is supplied with, 120 (Fig. 3 (c)) are identical with being with.

Anvil bar 150 is made of anvil bar 155 and 2 anvil bars 156,157.Anvil bar 155 has the long electrolysis of along continuous straight runs.2 anvil bars 156,157 at the two ends of anvil bar 155, have along the long electrolysis of vertical direction.Anvil 160 is made of anvil 165 and 2 anvils 166,167.Anvil 165 has the long electrolysis of along continuous straight runs.2 anvils 166,167 at the two ends of anvil 165, have along the long electrolysis of vertical direction.Anvil bar 155 and anvil bar 156,157 have formed electrolysis 155a, 156a, the 157a of H font.Similarly, at the two ends of anvil 165, connecting anvil 166, anvil 167.Anvil bar 155 and anvil bar 156,157 can combine the anvil bar of making respectively, also can make mutually integratedly on the basis of combination, perhaps, also can make integratedly.In addition, anvil 165, anvil 166 and anvil 167 can combine the anvil of making respectively, also can make mutually integratedly on the basis of combination, perhaps, also can make integratedly.But, in the packaging body manufacturing installation 101 of present embodiment, anvil bar 157 and anvil 167 with feedway 190 sides, with anvil bar 155,156, anvil 165, the 166th, split on one side with keeping tool 191 keeping being with, on one side with anvil bar 155,156, anvil 165,166 sealings, then, unclamp the maintenance that keeps 191 pairs of bands of tool, make to keep tool 191 after retreat without the 15b of content section, seal with anvil bar 157 and anvil 167.

In the bottom of the U font face 194 that keeps tool 191, formed the elongated concave surface channel mould 195 that embeds for 220 (Fig. 8 (c)).

Keep tool 191, when being with 220 to be sent here by pair of rolls 193, attract air from attracting mouthfuls 192, utilize this attractive force, be with 220 to become the U font being with 220 to be adsorbed on the U font face 194, making, supporting simultaneously this and be with 220.At this moment, in order will to insert in the bottom channel mould 195 of U font faces 194 with 220 effectively, the chock plug auxiliary member that also can not show with figure is being with 220 to embed in the channel moulds 195.Keep tool 191 keeping being with 220, and its direction towards U font face 194 is released, being with 220 to overlap without on the 115b of content section.

In addition, shown in Fig. 7 B (d) block diagram (e), band feedway 190 preferably has up and down 2 layers of maintenance tool 191a, 191b.With up and down 2

layers maintenance tool

191a, 191b retainer belt 220 (Fig. 8 (c)), can make with 220 shape and position certain.Therefore, usefulness is with the leak tightness of the shrinkage part of 220 raising packaging bodies, 210 ends and the effect stability of compressive resistance.

In addition, shown in the block diagram of Fig. 7 B (f), in the bottom with the concave shape face 194 of the maintenance tool 191 of feedway 190, also can not form the channel mould 195 (seeing Fig. 7 A (c)) of concave surface.Especially, as described later, after having carried out the sealing (the 1st sealing) of cross-directional, when keeping the sealing (2a sealing, 2b sealing) of tool 191 sides, even do not form the channel mould 195 (seeing Fig. 7 A (c)) of concave surface, also can implement sealing to three limits with 220 (Fig. 8 (c)).At this moment, for 220 spaces of guaranteeing to implement sealing (2b sealing) usefulness with feedway 190 sides, preferably form the face 194 of concave shape more deeply.

Below, except Fig. 7 A, Fig. 7 B, also with reference to the partial perspective view of Fig. 8 and the partial perspective view of Fig. 9, bringing together, seal and cutting off of packaging body 210 is described.

Shown in Fig. 8 (a), in the direction of transversal flat horizontal surface, bring together flat without the 115b of content section with bundling device 70.Shown in Fig. 8 (b), because this is brought together, attenuate without the 115b of content section.

On the other hand, shown in the partial perspective view of Fig. 9, in the band feedway 190, on one side be with 220 by pair of rolls 193 on one side crampings deliver to and keep tool 191 sides (seeing Fig. 9 (a)), be cut off into predetermined length (seeing Fig. 9 (b)).Here said " predetermined length ", refer to longer than the length along the channel mould 195 of the face 194 of the concave shape (U font) that keeps tool and concave surface, from the face 194 of the concave shape of maintenance tool 191 stretch out with 220 length.With 220 length of stretching out from the face 194 of concave shape, be that the part of stretching out does not hang down and can carry out 2a sealing (the 2nd sealing) and form the length at 2a sealing position 222 (seeing Fig. 8 (d), (e), (f), (g)) in the part of stretching out.This extension elongation is different because of the material, thickness etc. of band, to be advisable more than the 1mm and below the 15mm, preferably more than the 3mm and be preferably below the 10mm.Be with 220 after the cut-out, the attraction mouth 192 that is held tool 191 attracts, and forms the shape that overlaps with concave shape and is being held.The chock plug auxiliary member that does not show with figure embeds band in the channel mould 195 of concave surface, makes the shape neat (seeing Fig. 9 (c)) with 220.In addition, keep the width of tool 191, can be narrower than the width with 220, also can be identical with the width with 220.

Shown in Fig. 8 (b), through bringing together, attenuate without the 115b of content section.

Then, shown in Fig. 8 (c), what form the shape that overlaps with concave shape (U font) is with 220, brought together without the 115b of content section, surround and clip without content section 115b ground overlapping.That is, be with 220 to have concave surface shaped part 226, have the concave surface shaped part 227 of the flute profile of the bottom that is formed on concave surface shaped part 226.Here said " overlapping " is to instigate to be with 220 near to or in contact with without the 115b of content section so that brought together be positioned at part with the end of 220 large concave shape without the 115b of content section.That is, make maintenance tool 191 towards stretching out without the direction of the 115b of content section.

Then, with anvil bar 150 and anvil 160, as will be with 220 and clamp and welding without the 115b of content section followingly.

At first, shown in Fig. 8 (d), with anvil bar 155,156 and anvil 165,166, implement simultaneously the 1st sealing and 2a sealing (2a sealing process) (the 2nd sealing process).By these sealings, be with 220 and be sealed to one without the 115b of content section, formed respectively along transversal without long band shape the 1st sealing position 221 of the direction of the 115b of content section with along sealing position 222 with transversal direction without the 115b of the content section long band shape the 2nd of the direction of intersecting that meets at right angles.In addition, by these sealings, the circulation of the length direction of content C1 and air, moisture is sealed among the cylindrical body 115a.Therefore, cylindrical body 115a becomes the packaging body 210 of leak tightness.Be with 220 to can't help to keep tool 191 to keep, rest on the desired location of sealing.Then, keep tool 191 to retreat from the direction without the 115b of content section.

The 1st sealing position 221, comprised along long 2 layers banded weld 229-1, the 229-2 of transversal direction without the 115b of content section and be fused that part 229-1,229-2 clip along the long 1 layer of band shape of equidirectional weld 228 not.Weld 228, and under this restriction, the width of the 2nd sealing direction preferably has the following Design freedom of 3mm, more preferably below the 1.5mm, is preferably 0.75mm, carries out like this management of the 1st sealing.

Among Fig. 8 (e), represent in detail weld 229-1, the 229-2 at 2a sealing position 222, the 1st sealing position 221 and weld 228 not.

Shown in Fig. 8 (f), after maintenance tool 191 retreats, implement 2b sealing (the 2nd sealing) with anvil bar 157 and anvil 167, form 2b and seal position 223 (2b sealing process) (the 2nd sealing process).Owing to having implemented 2b sealing, be with 220 to become bag-shapedly, this bag-shaped peristome comprises content C1 direction (the crown attitude of being surrounded by the 1st sealing, 2a sealing, 2b sealing) towards packaging body 210.That is, become with 220 vertical downside (downstream of cylindrical body 115a) towards the bag 224 of below opening with 220 vertical upside (upstream side of cylindrical body 115a) bag 225 such 2 bags towards the top opening.In addition, implemented the 1st sealing and 2a sealing after, when implementing the 2b sealing with feedway 190 sides, maintenance tool 191 can not have the channel mould 195 of concave surface yet, becomes the shape of the maintenance tool 91 shown in Fig. 1 (c).

Here, the object of anvil bar 155 and anvil 165 crimping is to be with 220 and without the 115b of content section, be with 220 clamp and surround brought together without the state of the 115b of content section under carry out.On the other hand, the object of anvil bar 156 and anvil 166 and anvil bar 157 and anvil 167 crimping just is with 220.Therefore, the object thickness of anvil bar 155 and anvil 165 crimping is large, for this reason, anvil 166,167 electrolysis 166a, 167a is stretched out towards anvil bar 156 sides than the electrolysis 165a of anvil 165.Because anvil 166,167 electrolysis 166a, 167a stretch out, so, can be with predetermined extruding, crimping is thinner is fused thing (being with 220).Here said " predetermined extruding " refers to by material extruding that determine, that can form the crimping of suitable sealing.In addition, attenuate within reason, compressive resistance after the thicker extruding that is fused thing (bring together without the 115b of content section with 220) large, the sealing within reason are not reduced.In addition, the position adjustments of electrolysis, also the electrolysis 155a of available anvil bar 155 and anvil bar 156,157

electrolysis

156a, 157a carry out.

Shown in Fig. 8 (g), implemented the 1st sealing, 2a sealing and 2b sealing with ultrasonic wave welding device 200 after, tubular membrane F1, (Fig. 8 (f) locates, and is cut off device 80 and cuts off at the 1st hermetic unit 221 of band shape.Specifically, be cut off at the not weld 228 of the 1st hermetic unit 221, become the not weld 228-1 of upside, the not weld 228-2 of downside.At this moment, 2a seals position 222, also is cut off the not cut-out line of weld 228, side by side cuts into up and down two parts, after the cut-out, becomes the 2nd sealing position 222-1 of upside, the 2nd sealing position 222-2 of downside.In addition, 2b seals position 223, also is cut off the not cut-out line of weld 228, side by side cuts into up and down two parts, after the cut-out, becomes the 2b sealing position 222-1 of upside, the 2b sealing position 222-2 (cut-out operation) of downside.
