And formed.
Above-mentioned sealing container 100 by metal barrier 13 with outside light, oxygen gas and water
Separate absolutely.But, the sealing 101 of above-mentioned sealing container 100 from outer circumference end until inner circumferential
Hold and be communicated with thermoplastic resin 14, thus, worry the peripheral end face from sealing 101
The light of trace of intrusion, oxygen, moisture can invade collecting by thermoplastic resin 14
In portion 16.Even if their intrusion volume is trace, also can worry once to invade to resettlement section
16 can produce various problem.Such as, in sealing the containers for food use such as bag, once aerobic
Gas cut enters, and content will degenerate.If it addition, packed as lithium rechargeable battery
If electrolyte, then worry that once having moisture to invade will produce Fluohydric acid. and sealing property
Significantly reduce.
For the problems referred to above, patent documentation 1 proposes a kind of method, i.e. strength presses ballast
Folded laminate wrapping material so that barrier layer one another along peripheral direction with wire near to or in contact with
Mode seal.According to this encapsulating method, if making barrier layer closer to each other, then narrow
Thermoplastic resin can form narrow road, so that light etc. are difficult to invade.If it addition, intercepting
If layer contacts with each other, owing to thermoplastic resin interrupts at contact point, it is possible to stop

Stable.It addition, resin can be pushed in order to make barrier layer contact with each other, but when wire-shaped contact
Only push up against resin in single shaft side, therefore the mobility of resin is very poor.Thus, in order to really
Push resin on the spot and barrier layer is engaged with each other, need to impose severe pressure.It addition,
If remaining resin if pushing amount is not enough on joint interface, then can be formed and invade from outside
The path entered.If if there is non-bonding part in the part in wire-shaped contact portion, then light etc.
Can pass through from which and invade to internal with beeline, therefore barrier property can become unstable
Fixed.

[using the battery sealing container]
As it is shown on figure 3, in using the manufacture of battery 2 of above-mentioned battery housing 1,
In the recess 11 of the case half bodies 10b of one side house battery main body, and will respectively with battery master
Positive pole that the positive pole of body is connected with negative pole lead-in wire 20 and negative pole go between 21 be drawn out to outside
Portion, in this case, covers the case half bodies 10a of the opposing party and by sealing circumference 12
Overlap carries out encapsulation process.Above-mentioned positive pole lead-in wire 20 and negative pole lead-in wire 21 are respectively
By tab film (tab film) 22,23 clamping state under be arranged in sealing circumference 12,
Between 12.Therefore, if carrying out the encapsulation process of sealing circumference 12,12, then it is formed at
The first sealing 31 in lead-in wire 20,21 the most derivative parts, is directly bonded to upper and lower
Seal and use circumference 12,12, and be formed at second in the parts of 20,21 extractions that will go between
Sealing 32 is bonded to upper and lower sealing and uses via lead-in wire 20,21 and lead-in wire film 22,23
Circumference 12,12.Above-mentioned battery housing 1 is formed by two first sealings on all-round
The periphery sealing 30 that portion 31 and two the second sealings 32 are constituted, and at lead-in wire 20,21
The state lower seal being drawn out to outside housing.
[sealing the sealing of container]
On above-mentioned periphery sealing 30, it is formed at the most derivative part of lead-in wire 20,21
On the first sealing 31 corresponding with the sealing of the present invention, it is by heat-sealing portion and barrier layer
Junction surface and constitute.
As shown in fig. 4 a and fig. 4b, the first sealing 31 by by thermoplastic resin 14,
The deposition of 14 and the heat-sealing portion 33 that formed and the resin pushing thermoplastic resin 14 and make
Multiple barrier layer junction surfaces 34 that barrier layer 13,13 is engaged with each other and formed.Above-mentioned heat-sealing
In the whole region of the width that portion 33 is formed at the first sealing 31, in contrast,
In the zone line 35 that barrier layer junction surface 34 is made only on width, inner circumferential lateral areas
There is not barrier layer junction surface 34 in territory 36 and outer circumferential side region 37, and only exist heat-sealing
Portion 33.
Above-mentioned heat-sealing portion 33 is uninterrupted in the whole region of the first sealing 31, but even
Continue, in contrast, multiple barrier layer junction surface 34 is the most discontinuous, and in heat-sealing portion 33
In with mottled existence.It addition, each barrier layer junction surface 34 be shaped as two cornerwise
The rhombus (square) that length is equal, two diagonal are along the periphery of the first sealing 31
Direction and width and configure.It addition, these barrier layer junction surfaces 34 are at sealing 30
Width on be configured to multiple row, and relative to peripheral direction and width the two side
To with zigzag arranged askew with staggered configuration.The configuration at this barrier layer junction surface 34
For the closeest configuration of rhombus, the heat-sealing portion 33 in zone line 35 is by barrier layer junction surface
The closeest configuration of 34 and form oblique grille-like.
The deterioration come from container external belt promotes that thing is interdicted completely by barrier layer 13, but has
There may be trace to enter in thermoplastic resin 14.Therefore, shown in Fig. 4 A
In the vertical view of one sealing 31, the deterioration entered from peripheral end face promotes that thing is only along heat-sealing portion
33 arrive in container, and heat-sealing portion 33 becomes intrusion path.Above-mentioned heat-sealing portion 33 is blocked layer
Junction surface 34 clips and forms narrow road, and the sectional area invading path diminishes, and thus deteriorates promotion
The intrusion of thing is inhibited.Further, since above-mentioned heat-sealing portion 33 is from the first sealing 31
Outer circumference end be connected in the zone line 35 of inner side as oblique grille-like, so deterioration promotes
The intrusion path 38,39 of thing can become roundabout and avoid the jagged of barrier layer junction surface 34
Route 38 or become angled straight lines 39.Jagged intrusion path 38 and angled straight lines
Intrusion path 39 and route S-phase longer than distance, this route S be by with the first sealing
The route of the beeline represented by straight line that the periphery of 31 is orthogonal, invades path by extending
Distance suppress deterioration promote thing intrusion.As it has been described above, present embodiment is first close
Envelope portion 31 promotes the sectional area invading path of thing by reducing deterioration, and extends intrusion path,
And synthetically suppress to invade, improve barrier.
It addition, barrier layer junction surface 34 and heat-sealing portion 33 phase making resin deposition each other
More higher than adhesion.Thus, by formation barrier layer junction surface 34 in heat-sealing portion 33
Peel resistant strength is improved relative to from outside stress.
Owing to the sealing 31 of the present invention there are multiple resistance with mottled in heat-sealing portion 33
Interlayer junction surface 34, so the width in heat-sealing portion 33 has essentially become the width of sealing 31
Degree W1 (with reference to Fig. 4 A).The present invention is not limiting as the width W1 of sealing 31, but is
Guarantee bond strength relative to the intrinsic pressure of container, be preferably formed as width W1 be 1mm with
On sealing 31.If it addition, width W1 is 10mm, then can sufficiently be connect
Close intensity.Accordingly, it is preferred that the width W1 of sealing 31 is 1～20mm.On it addition,
The preferred value of the width W1 stating sealing 31 also can be by the thickness of thermoplastic resin 14
With the impact of the MFR value of resin, therefore, it is preferably according to these situations, suitably sets
In the range of 1～20mm.The width W1 of especially preferred sealing 31 is 3～10mm.
Further, since the inner peripheral side end portion of sealing 31 can contact content, so it is excellent
Elect as and only formed by the material of thermoplastic resin 14.Some content must avoid or
The material with barrier layer 13 (such as metal) is preferably avoided to contact.Such as, if battery
If, it is necessary for avoiding electrolyte to contact with metal barrier layer 13.It is thus preferable that
In the region, inner circumferential side 36 of sealing 31, it is not provided with barrier layer junction surface 34, and is only formed
There are the region in heat-sealing portion 33, said structure also be able to use safely needs avoid with
In the packaging of the content of barrier layer contact.The width W2 in region, above-mentioned inner circumferential side 36 is preferred
It is 3～15mm, especially preferably 5～10mm.On the other hand, sealing 31 is not limited
No barrier layer junction surface 34 is had in outer circumferential side region 37.
As illustrated by according to above-mentioned embodiment, on sealing 31, by reducing deterioration
Promote thing invade path sectional area, or make further intrusion path roundabout extend away from
From, can suppress to invade deterioration and promote the intrusion of thing.
As long as reducing of the sectional area of above-mentioned intrusion path invades the width of path i.e.
Can, as long as invade path width reduce be discontinuously formed in heat-sealing portion 33 multiple
Barrier layer junction surface 34, just can with the shape at barrier layer junction surface 34 and forming position independently
Realize.The width invading path is the interval D between barrier layer junction surface 34, therefore, logical
Crossing constriction interval D can suppress deterioration to promote the intrusion (with reference to Fig. 4 A) of thing.On the other hand,
In order to so that the amount that reduces of interval D between barrier layer junction surface 34 is to push resin, lead
Cause to need the processing conditionss such as bigger pressure to become strict, and, in the feelings that resin is not pushed out
Under condition, it is impossible to make barrier layer 13 contact with each other, thus barrier layer junction surface 34 cannot be formed.
From this viewpoint, being preferably, the interval D between barrier layer junction surface 34 is set in
In the range of 0.2～3mm, especially preferably 0.5～1.5mm.
It addition, about the size at each barrier layer junction surface 34, preferably its circumscribed circle is a diameter of
0.2～5mm, especially preferably 0.5～1.5mm.
It addition, invade the expanding by the shape at barrier layer junction surface 34 or shape of the distance of path
Position or combinations thereof is become to be capable of.As shown in Figure 4 A, the shortest intrusion is led to
Road is positioned on the straight line S orthogonal with the periphery of sealing 31, with beeline cross this first
Distance in the case of sealing 31 is the size of the width W1 of sealing 31, therefore,
As long as there is at least one barrier layer junction surface 34 on above-mentioned straight line S, then just can lead to
Cross by roundabout for this barrier layer junction surface 34 and extend invade path distance.Therefore, if with
Make to there is at least one barrier layer on the arbitrary line S orthogonal with the periphery of sealing 31 to connect
The mode in conjunction portion 34 configures barrier layer junction surface 34, and the intrusion path of above-mentioned beeline will
Becoming not exist, invading path will be elongated compared with the width W1 of sealing 31.It addition,
As shown in Figure 4 A, if forming multiple row barrier layer junction surface on the width of sealing 31
34, the most roundabout number of times will increase, therefore, it is possible to make the distance of intrusion path become longer.
But, if increasing columns in limited width W1, then between barrier layer junction surface 34
Interval also can narrow, and the flowing of the resin pushed easily is retarded by silt, and thus, columns is preferably
Below 20 row.
The sealing 40 of Fig. 5, in heat-sealing portion 41, makes and the barrier layer of Fig. 4 A same shape
Junction surface 34 is not with staggered and configure in column.In the case of this configuration in column, along outward
The straight line 42 passed through between the barrier layer junction surface 34 that circumferential direction is adjacent is, beeline
Invading path, this straight line is the shortest by represented by the straight line orthogonal with the periphery of sealing 40
The route S of distance, therefore, it is impossible to extend the distance invading path.Additionally, due to it is above-mentioned close
Envelope portion 40 has been discontinuously formed multiple barrier layer junction surface 34, has by reducing intrusion logical
The sectional area on road suppresses the effect of the intrusion of deterioration promotion thing, so comprising in the present invention.
[other shape examples at barrier layer junction surface and configuration example]
Sealing 45,50,55,60 shown in Fig. 6～Fig. 9 is its of the sealing of the present invention
His embodiment.

Both direction in the way of zigzag oblique arrangement with the example of staggered configuration.This sealing
62 is the rhombus that two cornerwise length is different, and longer diagonal 63 is along peripheral direction
And configure.That is, above-mentioned barrier layer junction surface 62 is rhombus longer in peripheral direction.
Make the inclination angle invading path 64 of straight line in the sealing 60 of the closeest configuration of rhombus
Spend α, i.e. by the road of the beeline represented by the straight line orthogonal with the periphery of this sealing 60
Line S and straight line invade path 64 the angled interior angle being this rhombus 1/2.In above-mentioned
Angle is in two pairs of interior angles, be positioned on the straight line S orthogonal with the periphery of sealing 60 a pair
Interior angle.Therefore, above-mentioned interior angle 2 α becomes the biggest, just invades the tilt angle alpha of path 64
Becoming the biggest, distance just becomes the longest, and deterioration promotes that the intrusion inhibition of thing just becomes more
Greatly.Above-mentioned interior angle 2 α is determined by two cornerwise length, in two diagonal of rhombus
Longer diagonal 63 along peripheral direction, and the difference of cornerwise length becomes the biggest,
The distance then invading path 64 becomes the longest, thus obtains invade corresponding with distance and suppress effect
Really.
Owing to interior angle 2 α of the rhombus shown in Fig. 9 is obtuse angle, so invading inclining of path 64
Rake angle α is more than 45 °.Therefore, in the sealing making the closeest configuration of rhombus, if by Pedicellus et Pericarpium Trapae
Shape to make longer diagonal configure in the way of peripheral direction, then the intrusion path of straight line
The tilt angle alpha of 64 is more than 45 °.On the other hand, due to the resistance of sealing 31 of Fig. 4 A
Interlayer junction surface 34 is the rhombus (square) that two cornerwise length is equal, so invading
The tilt angle alpha entering path is 45 °.In other words, be orthogonal to above-mentioned sealing 31
Periphery straight line angled on the arbitrary line less than 45 °, there is at least one resistance
, there is not the intrusion path of the tilt angle alpha straight line less than 45 ° in interlayer junction surface 34.
As it has been described above, in the case of the closeest configuration in barrier layer junction surface making rhombus, preferably
For giving difference to two cornerwise length, by longer diagonal configuration along periphery
On the direction in direction, cornerwise length difference becomes the biggest, then deterioration promotes that the intrusion of thing presses down
Effect processed becomes the biggest.It addition, the preferred size of rhombus is, the size of long-diagonal be 0.05～
20mm, the size of short diagonal is 0.02～10mm, and especially preferred size is, long diagonal angle
The size of line is 0.5～3mm, and the size of short diagonal is 0.2～1.2mm.
It addition, the distance invading path of straight line is along with orthogonal relative to the periphery with sealing
Straight line invade path angle of inclination become the biggest and become the longest, this situation does not limit
It is the situation of rhombus due to above-mentioned barrier layer junction surface, is all common in any shape.
Therefore, if with the straight line of the periphery being orthogonal to sealing angled any for less than 45 °
On straight line, there is at least one barrier layer junction surface, the most there is not angle of inclination less than 45 °
The intrusion path of straight line, the angle of inclination invading path of straight line becomes more than at 45 °,
To the intrusion inhibition that deteriorate promotion thing corresponding with above-mentioned angle.
