As the bag that can carry out simply sealing, such as, the bag (for example, referring to patent documentation 1 (Fig. 1, Fig. 4)) that the band proposing in a kind of tongue piece portion carrying out bending to cover opening or have adhesive strip in the part covered by tongue piece portion seals.In addition, propose a kind of on the inside face of bag the bag (for example, referring to patent documentation 2 (Reference numeral 11 of Fig. 2, Fig. 4, Fig. 5)) along opening mounting clamp taut band.
Patent documentation 1: Japanese Unexamined Patent Publication 2008-273559 publication
Patent documentation 2: Japanese Unexamined Patent Publication 2007-191200 publication
Summary of the invention
the problem that invention will solve
Carry out the bag of that seal, so-called shape of healing up as making the inside face of bag align each other, it is normally provided with the bag of the shape of healing up of clamping band, and uses the bag of the shape of healing up having the band of adhesive strip to seal also not reach practical.That is, the bag inside face of bag with the band adhesive strip of the shape of healing up of adhesive strip does not also reach practical.
Such as, (a) as the Figure 10 as birds-eye view and the line X-X as (a) along Figure 10 carry out shown in (b) of Figure 10 of the cutaway view of cutting, had in the bag-shaped bag 10x of opening at resin sheet 12 by along following 10n doubling and along top 10m, by cutting molten for resin sheet under the state folded up by resin sheet, thermal seal 21 can be formed along opposite side 10s, a 10t.When being cut together with resin sheet is molten by adhesive strip under the state of resin sheet by adhesive tape joining, the whole width of the adhesive strip 13 being formed with bonding coat 14 between opposite side 10s, a 10t can will be pasted on the inside face 12n of bag 10x on a face of off-tape 16.When so utilizing molten cutting, a bag 10x can be manufactured efficiently.
But, even if the relative part of resin sheet 12 is sealed each other well by the combination of the material of resin sheet 12, off-tape 16 and this three of bonding coat 14, also there is following situation: in off-tape 16 and bonding coat 14 and the equitant part 30x of this three of resin sheet 12, also cannot be bonded even if carry out molten cutting.In this case, in bag 10x, easily break from the bad part 30x of sealing, thus likely cannot seal.
Also adhesive strip 13 is expected to paste in the mode of dividing out with opposite side 10s, a 10t, not produce poor sealing part 30x.But, if resin sheet 12 part respect to one another mutual produced gap by between the part that seals and the two ends of adhesive strip 13, and cannot to seal.Be difficult to produce bag in a large number when not producing such gap.
In addition, also expect bag outside adhesive-applying or paste other components to cover poor sealing part 30x.But, namely allow to sealing, the aesthetic property of bag also can be made to be deteriorated and make Fabrication procedure also become complicated.
On the other hand, according to the difference of the array mode of the material of resin sheet 12, off-tape 16 and this three of bonding coat 14, carry out molten cutting if exist, the situation that off-tape 16, bonding coat 14 and the equitant part 30x of this three of resin sheet 12 can be bonded.In this case, the two ends due to off-tape 16 are bonded to resin sheet 12, even if therefore peeled by off-tape 16 auto-adhesive layer 14, off-tape 16 also cannot be made to be separated with bag.If for making off-tape 16 be separated with bag by force, then bag can be made to break.
Therefore, the bag inside face of bag with the band adhesive strip of the shape of healing up of adhesive strip does not also reach practical.
The present invention can seal and the bag of the band adhesive strip of the shape of healing up that can manufacture efficiently for providing a kind of in view of these actual conditions.
for the scheme of dealing with problems

Detailed description of the invention
Below, reference Fig. 1 ~ Fig. 7 is while illustrate embodiments of the present invention.
embodiment 1
While illustrate that with reference to Fig. 1 ~ Fig. 3 the bag 10 of the band adhesive strip of the shape of healing up of embodiment 1 is (hereinafter simply referred to as " bag 10 ".)。
(a) of Fig. 1 is the birds-eye view of bag 10.(b) of Fig. 1 is by the cutaway view of bag 10 along the line X-X cutting of Fig. 1 (a).(a) of Fig. 2 is by the cutaway view of bag 10 along the line A-A cutting of Fig. 1 (a).(b) of Fig. 2 is by the cutaway view of bag 10 along the line B-B cutting of Fig. 1 (a).
As depicted in figs. 1 and 2, bag 10 is by making the resin sheet 12 after folding be formed as bag-shaped.As shown in Figure 2, resin sheet 12 fold in roughly W shape and has: section 1 12a and part 2 12b, this section 1 12a and part 2 12b are folded and toward each other and outside face 10a, 10b of formation bag 10; And edge break (gusset) portion 12c, it is by the part between section 1 12a and part 2 12b is folding to the inside.
As shown in (a) of Fig. 1, outside face 10a, 10b of bag 10 have rectangular shape.On bag 10, by be heated by the section 1 12a of resin sheet 12 and part 2 12b along opposite side 10s, a 10t and fit, thus form thermal seal 21.If (a) of Fig. 1 is with shown in Fig. 2, the top 10m between one end 10p, 10q along opposite side 10s, a 10t is formed with opening 10z.The following 10n between the other end 10u, 10v along opposite side 10s, a 10t is formed with the end.
As shown in (a) of Fig. 2, the inside face 12n (that is, the face of that contrary with the outside face 10b of bag 10 side) of the part 2 12b of resin sheet 12 is pasted with adhesive strip 13.Specifically, the inside face 12n of the part 2 12b of resin sheet 12 is bonded with a first type surface 14n of the bonding coat 14 of adhesive strip 13.As shown in Figure 1, bonding coat 14 is continuous between opposite side 10s, a 10t, and the two ends of bonding coat 14 arrive opposite side 10s, a 10t.In adhesive strip 13, off-tape 16 is adhered to another first type surface 14m of bonding coat 14 in the mode that can peel off, and off-tape 16 covers bonding coat 14.As shown in Figure 1, off-tape 16 is also continuous between opposite side 10s, a 10t, and the two ends of off-tape 16 arrive opposite side 10s, a 10t.When being peeled by off-tape 16 and another first type surface 14m of the bonding coat 14 exposed is adhered to inside face 12m (face of that side contrary with the outside face 10a of bag 10) of the section 1 12a of resin sheet 12, the state after making bag 10 closed can be kept.
As being schematically shown in (b) of Fig. 1 and Fig. 2, at bag 10 between outside face 10a, 10b, by ultrasonic bonding and be formed with a pair ultrasonic bonding portion 20 both ends of both off-tape 16 and bonding coat 14 (that is, being the neighbouring part at two ends, left and right and two ends, left and right in FIG) and resin sheet 12 fitted each other.Ultrasonic bonding portion 20 can be utilized reliably to be sealed by bag 10.Such as, the resin sheet 12 of PP (polypropylene) and the off-tape 16 of PE (polyethylene) cannot by fitting for the formation of molten the cutting of thermal seal 21, if but utilize ultrasonic bonding, then this resin sheet 12 and this off-tape 16 can be bonded.
That is, fitted each other by the part of softening because of heat of resin sheet 12 when the sheet material of resin sheet 12 melts and cuts by limit 10s, the 10t along bag 10 and form thermal seal 21.When carrying out molten cutting, although the adhesive strip 13 forming off-tape 16 and bonding coat 14 also can be cut off simultaneously, even if there is off-tape 16 Yin Re and the softening situation that can not be adhered to resin sheet 12.In this case, as shown in (a) of Fig. 1, the part 30x between the section 1 12a being clamped in resin sheet 12 of off-tape 16 and part 2 12b cannot seal.Therefore, such as, when being peeled by off-tape 16, at the part place adjacent with off-tape 16 of thermal seal 21, bag 10 likely cannot be sealed by peeling by the section 1 12a of resin sheet 12 and part 2 12b.If form ultrasonic bonding portion 20, then bag 10 reliably can be sealed.
In order to bag 10 is reliably sealed, preferably to form ultrasonic bonding portion 20 along opposite side 10s, a 10t across the mode of two sides 16s, 16t of off-tape 16.That is, ultrasonic bonding portion 20 is preferably formed to and has: (a) boundary line 20s, 20t, and this boundary line 20s, 20t and thermal seal 21 separate and across side 16s, 16t of off-tape 16; And (b) extension 20x, 20y, this extension 20x, 20y only carry out ultrasonic bonding to resin sheet 12 along this boundary line 20s, 20t and are formed, and this extension 20x, 20y contact with side 16s, 16t of off-tape 16.
Such as, PE (polyethylene) though off-tape 16 be stretched and also can extend, therefore, be difficult in this case off-tape 16 is ruptured at desired locations, if but form the ultrasonic bonding portion 20 of side 16s, the 16t across off-tape 16 as described, then can be easy to make off-tape 16 along boundary line 20s, 20t fracture, and the residual limit be stretched can not be remained.
In addition, preferably, to overlap with thermal seal 21 or the mode adjacent with thermal seal 21 forms ultrasonic bonding portion 20.
As shown in Figure 1, if ultrasonic bonding portion 20 is formed in the mode of side 16s, 16t across off-tape 16, then when off-tape 16 is peeled, off-tape 16 is easy to break along boundary line 20s, the 20t in the ultrasonic bonding portion 20 be formed between the section 1 12a of resin sheet 12 and part 2 12b, thus all parts between ultrasonic bonding portion 20 of another first type surface 14m of bonding coat 14 are exposed.Therefore, bonding coat 14 is continuous between ultrasonic bonding portion 20, thus bonding coat 14 can be adhered to the inside face 12m of the section 1 12a of resin sheet 12, reliably can seal thus by between ultrasonic bonding portion 20.
In addition, because ultrasonic bonding portion 20 is across side 16s, 16t of off-tape 16, therefore, no matter off-tape 16 is peeled towards top 10m from following 10n, or peeled towards following 10n from top 10m by off-tape 16, off-tape 16 all can break along boundary line 20s, the 20t in ultrasonic bonding portion 20.Therefore, regardless of the direction that off-tape 16 is peeled, all parts of another first type surface 14m of bonding coat 14 all can be made to expose between ultrasonic bonding portion 20, thus reliably can seal between ultrasonic bonding portion 20.
Utilize edge break portion 12c to increase to make the area at the end of bag 10, therefore, bag 10 is suitable for storage stereoscopic article and is easy to just erect with self under receiving state.
In addition, also can be, edge break portion is not set, but by resin sheet only with other structures of cross section roughly V shape doubling etc.
When making it be formed as bag-shaped when being folded by resin sheet 12, because resin sheet 12 is continuous at the end of bag 10, be therefore easy to the intensity at the end of guaranteeing bag 10, so preferably.But, also can be resin sheet 12 is not folded to make it be formed as bag-shaped, but by superimposed for multiple resin sheet, and except opening, multiple resin sheet is bonded along limit and makes it be formed as bag-shaped.
If bag is rectangle, then can reduce the waste of material, so preferably, but bag also can be the shape beyond rectangle.In this case, opposite side 10s, a 10t also can be made to be formed as such as curve shape.
Resin sheet 12 both can be transparent, and also can be opaque, can also be semi-translucent, also can printing word, figure etc. as required.Also the disciform through hole etc. of the through hole of the circle being used for suspended bag 10, sharp handle dominated by hand can be formed in the part between top 10m and off-tape 16 of resin sheet 12.
In addition, also can be on top folding between 10m and off-tape 16 by resin sheet 12.In this case, also adhesive strip 13 can be pasted onto resin sheet 12 by the part after folding to the inside.
Next, reference Fig. 3 is while illustrate the Fabrication procedure of bag 10.Fig. 3 is the skeleton diagram schematically showing Fabrication procedure.
As shown in Figure 3, first, the sheet material 22 of web-like and the adhesive strip 24 of web-like is prepared.As sheet material 22, use the resin sheet (resin molding) of such as OPP (Biaxially oriented polypropylene), CPP (tensionless winkler foundation polypropylene) etc.In adhesive strip 24, stick with paste for the formation of the bonding be coated with continuously for the formation of bonding coat 14 on a first type surface 24b of the resin strip 24a of the PE (polyethylene) etc. of off-tape 16.
Then, rolling out sheet material 22 and after paste adhesive strip 24 on a first type surface 22a of sheet material 22, by using the method for not shown set square etc., sheet material 22 be folded into cross section roughly W shape.Now, the first type surface 22a being pasted with adhesive strip 24 of sheet material 22 is made to be positioned at inner side.
Then, as shown in arrow 28, make the vibration face (not shown) of ultrasonic variable amplitude bar (Japanese: ultrasonic ホ ー Application) be connected to sheet material 22, and form ultrasonic bonding portion 20 in the both sides of the imaginary cutting line 22x that will be cut off by sheet material 22 with the spacing of regulation in the mode being provided with interval 20u.
Then, as shown in arrow 29, carry out molten cutting at imaginary cutting line 22x, thus isolate the bag 10 being formed with thermal seal 21 by molten cutting.
By above operation, the bag 10 being formed with ultrasonic bonding portion 20 and thermal seal 21 can be manufactured efficiently.For the Fabrication procedure of bag 10, as long as at feeding sheets 22 continuously while add the operation of pasting adhesive strip 24 and the operation forming ultrasonic bonding portion 20 in the Fabrication procedure in the past of molten section material 22.
