The manufacture method of the diaphragm seal of present embodiment has the method for the diaphragm seal of grabbing the portion of pinching for the operation manufacturing by following (1) and (2).
(1) shown in Figure 1A, Fig. 2 A, it is folding along the broken line 1c that extends in its grain direction to have first base material 1 that the long ribbon shape film of sealant layer constitutes by single face, make that the back side of described sealant layer is relative, afterwards shown in Figure 1B, Fig. 2 B, second base material 2 that a part 1a among two part 1a, the 1b that first base material 1 is divided into by broken line 1c is constituted towards the long ribbon shape film that is had sealant layer by single face, the sealant layer of two base materials 1,2 is overlapping relative to each other, thus the part 1a of a side of first base material 1 is pasted on second base material 2.
Thus, shown in Fig. 1 C, Fig. 2 C, obtained the layered product 4 that the stickup by first and second base material forms.
And, when in Figure 1B, Fig. 2 B, carrying out hot sticky subsides with hot plate, for the sealant layer of the part that prevents from first base material 1 and second base material 2 not paste mutually deposited to hot plate etc., with can not be deposited film (polyethylene terephthalate (PET) film, nylon membrane, the film of handling through fluorine or silicon or layer etc.) mixing to sealant layer the sealant layer side that is set to the described not part of stickup for well.
As this can deposited film to sealant layer, if equally use the long ribbon shape film, then can stack and transport with base material 1,2 with first base material 1 and second base material 2.
(2) shown in Fig. 1 D, Fig. 2 D, by predetermined shape layered product 4 is carried out punching press, and make the punching press scope comprise the part of broken line 1c, form the portion of pinching 5 of grabbing that constitutes by first base material 1 and second base material, 2 mutual part 1a, the 2a that paste.Like this, as shown in Figure 3, obtain having the diaphragm seal 6 of grabbing the portion of pinching 5.
In the present embodiment, also can be shown in Figure 1A-1D, making first base material 1 is two each sides that comes corresponding second base material 2.And, also can be shown in Fig. 2 A-2D, form broken line 1c at two places of first base material 1, and a described part 1a that will paste second base material 2 is formed on the both sides of the edge portion of first base material 1.By these methods, on the layered product 4 of each base material, can form broken line 1c at two places, therefore diaphragm seal can be made with two row punching presses.
When being present in as shown in Figure 4 on the cylindrical portion 7a with diaphragm seal sealed opening portion, the structure of this cylindrical portion 7a when having peristome on the top, basic identical and the stretching out as far as possible less for well laterally of the external diameter of the diameter of the punching press shape of diaphragm seal and this cylindrical portion 7a.And when using diaphragm seal sealed opening portion opening at smooth wall, the size of described punching press shape is preferably the width of the leakproofing material that can guarantee the peristome outside.
According to the diaphragm seal 6 of present embodiment manufacturing, as shown in Figure 4, can be by its outer edge 6a being pasted the circumference 9 of the peristome of container 7, and use as the diaphragm seal of sealing peristome.And when to the cylindrical portion cover lid 8 of container 7, this diaphragm seal 6 can be as the inner seal film that uses in the inboard of lid 8.
And, use according to the diaphragm seal 6 of present embodiment and make when having the container of inner seal film, can adopt method as shown in Figure 5.Promptly, on the circumference 9 of the peristome of container 7, carry the 3rd base material 3, the shape of the 3rd base material 3 is identical with the punching press shape of diaphragm seal 6, its two-sided sealant layer that has, and its inside has metal level, on the 3rd base material 3, carry and be formed with first and second base material 1 described in the diaphragm seal 6 of grabbing the portion of pinching 5,2 parts of not pasting mutually, and at described opening of container cover lid 8, inboard at this lid 8, diaphragm seal 6 and the 3rd base material 3 are being carried out the high-frequency induction heating under the state of circumference 9 crimping of opening of container, thus, with between diaphragm seal 6 and the 3rd base material 3, and paste between the circumference 9 of the 3rd base material 3 and opening of container.
Thus, diaphragm seal 6 can be determined the position in the inside of lid 8 with respect to the circumference 9 of opening of container, so that the location of diaphragm seal 6 becomes is easy.At this moment, arrive the 3rd base material 3 in-to-in metal levels in order to make high frequency, cylindrical portion 7a and lid 8 are made of insulators such as plastics at least in the container 7.
As the method for on the circumference 9 of opening of container, carrying the 3rd base material 3 and diaphragm seal 6, preferential following method.That is, will have the inside that downward diaphragm seal of grabbing the portion of pinching 56 and the 3rd base material 3 install to lid 8 in this order in advance, the lid 8 that sealing film 6 and the 3rd base material 3 will be housed again covers on the opening of container.
According to the method, compare on the circumference 9 of opening of container and to carry after the 3rd base material 3 and the diaphragm seal 6 method of cover lid 8 again, even on the machine of automation, also can easily implement.
During open container, tear stripping by the portion of pinching 5 of grabbing that pinches diaphragm seal 6 with finger etc., easily open container.As shown in Figure 4, the portion of pinching 5 of grabbing of diaphragm seal 6 constructed in accordance forms the structure that projects upwards from the peristome of container, is easy to grab and pinches so grab the portion of pinching 5.
In addition, when use has the container of inner seal film according to diaphragm seal 6 manufacturing of present embodiment, on the circumference 9 that diaphragm seal 6 is directly carried opening of container, also can be as shown in Figure 6A, between the circumference 9 of the 3rd base material 3 and opening of container, but the 4th base material 21 that paste on the two sides is set, carries the 3rd base material 3 and diaphragm seal 6 more thereon.
At this moment, the punching press shape that will have the downward diaphragm seal of grabbing the portion of pinching 56, shape and diaphragm seal 6 is identical and but two-sided the 4th base material of sealant layer and inner the 3rd base material 3 two sides that have metal level pasting 21 that has installs to after lid 8 the insides in this order, covers on the peristome of container 7 sealing film 6 and top the 3rd base material 3 thereof and the lid 8 of the 4th base material 21 are housed.In the inboard of this lid 8, diaphragm seal 6 is being carried out the high-frequency induction heating under the state of circumference 9 crimping of described opening of container.
Thus, the heat that utilizes high frequency to produce in the inside of the 3rd base material 3, between the circumference 9 with diaphragm seal 6 and opening of container (between following and the 3rd base material 3 of diaphragm seal 6 top, following and the 4th base material 21 of the 3rd base material 3 top between and between the circumference 9 of the following and opening of container of the 4th base material 21) paste mutually.
The 4th base material 21 materials by Pastings such as thermoplastic base resins constitute, and especially have stronger sticking strength between the circumference 9 of the 4th base material 21 and opening of container for well.Like this, when grab pinch grab the portion of pinching 5 tear peel diaphragm seal 6 off after, shown in Fig. 6 B, the 4th base material 21 can remain in circumference 9 places of opening of container.
Polygon, star, circular peristome or the peristome 22 of porous or mesh can be set on the 4th such base material 21, thus, can utilize the outflow of the content that peristome 22 controls pour out from container 7.
For example, when content is dope such as mayonnaise, be suitable shape, can make the cross sectional shape of the content poured out from container 7 form special shape such as star and pour out by the periphery 23 that makes peristome 22.
According to the present invention, the punching press by layered product 4 forms diaphragm seal 6, so it is identical in the semi-round periphery of grabbing the portion of pinching 5 and the diaphragm seal 6 opening of container to be carried out the shape of periphery of leak free circular portion.Therefore, grabbing the periphery of the portion of pinching 5 can be not protruding from the circular portion of diaphragm seal 6.And the diameter of circular portion of grabbing the maximum width of the portion of pinching 5 and diaphragm seal 6 is roughly the same, so it is bigger to guarantee to grab the size of the portion of pinching 5.
Grab the existing method of the portion of pinching 5 as formation, 1-3 puts down in writing as patent documentation, a film is folded into after the chevron inboard is pasted (for example with reference to patent documentation 3 Fig. 3) with alite paste etc.The 30th of patent documentation 3 the section and Fig. 6 put down in writing for another example, and the inner seal film is divided into two pasters, and only form the outstanding portion of pinching of grabbing on the part of left and right sides paster, about making again grab the portion of pinching overlap each other ground opposite one another after, it is deposited to grab the portion's of pinching heating.
But, in being folded into the method for chevron, the inboard that forms the part of chevron being pasted, the difference in thickness of the each several part of base material is big, is unsuitable for using the long ribbon shape film to make.
In addition, the method for the 30th section record of patent documentation 3 is that the portion of pinching of grabbing that will be formed on highlightedly in advance on the paster of the left and right sides carries out overlapping depositedly, in the method, is difficult to exactly to last position of grabbing the portion of pinching for a short time, the problem that can stagger in the location.
Again, at this moment, cause for fear of staggering and to grab stretching out of the portion of pinching, need to grab the portion of pinching and become on the part of circular pad pasting than ninor feature because of the position.
With respect to this, according to the present invention, then grabbing the portion of pinching 5 will form by punching press after two films stickups, thus can avoid grabbing stretching out of the portion of pinching 5, and can easily form than being easy to grab the portion of pinching 5 of grabbing of pinching greatly.
And, though herein, be to make broken line 1c be equivalent to the diameter of the circular portion of diaphragm seal 6 when punching press, and be that punching press is carried out at the center with broken line 1c, also can be partial to a certain side, make the area of grabbing the portion of pinching 5 be greater than or less than half of circular portion area.In addition, though herein, punching press be shaped as circle, also can be other shapes, as polygons such as oval, quadrangle or hexagons.Even also can, after diaphragm seal 6 is come out from layered product 4 punching presses, such as adjusting shape by the methods such as a part of removing the periphery of grabbing the portion of pinching 5.
Below, to the diaphragm seal that constitutes by three base materials among the present invention and use the manufacture method that has the inner seal film container of sealing film to describe.

According to the diaphragm seal 16 of present embodiment manufacturing, as shown in figure 10, can be by its outer edge 16a being pasted the circumference 19 of the peristome of container 17, and use as the diaphragm seal of sealing peristome.And when to the cylindrical portion cover lid 18 of container 17, this diaphragm seal 16 can be as the inner seal film that uses in the inboard of lid 18.
In the diaphragm seal 16 of present embodiment, the 3rd base material 13 preferably has sealant layer by the two sides and the inner long ribbon shape film that has metal level constitutes.At this moment, use the diaphragm seal 16 of present embodiment to make when having the container of inner seal film, can adopt method as shown in figure 11.Promptly, on the circumference 19 of opening of container, carry and be formed with the diaphragm seal 16 of grabbing the portion of pinching 15, and at opening of container cover lid 18, inboard at this lid 18, in with diaphragm seal 16 the 3rd base material 13 1 sides under the state of circumference 19 crimping of opening of container, carry out the high-frequency induction heating, thereby paste between the circumference 19 with the 3rd base material 13 of diaphragm seal 16 and opening of container.
Thus, diaphragm seal 16 can be determined the position in the inside of lid 18 with respect to the circumference 19 of opening of container, and therefore, it is easy that the location of diaphragm seal 16 becomes.At this moment, arrive the 3rd base material 13 in-to-in metal levels in order to make high frequency, cylindrical portion 17a and lid 18 are made of insulators such as plastics at least in the container 17.
As the method for on the circumference 19 of opening of container, carrying diaphragm seal 16, the method that is preferably as follows.Promptly, to have the inside that the downward diaphragm seal of grabbing the portion of pinching 15 16 installs to lid 18 in advance, the lid 18 that sealing film 16 will be housed again covers on the peristome of container 17, and the face of the 3rd base material 13 1 sides of diaphragm seal 16 is docked with the circumference 19 of opening of container.
According to the method, compare on the circumference 19 of opening of container and to carry after the diaphragm seal 16 method of cover lid 18 again, even on the machine of automation, also can easily implement.
The diaphragm seal 16 of present embodiment, because before the punching press of carrying out layered product 14, the 3rd base material 13 has pasted on first and second base material 11,12, so can avoid the dislocation between first and second base material 11,12 and the 3rd base material 13.
In addition, use the diaphragm seal 16 of present embodiment to make when having the container of inner seal film, on the circumference 19 that diaphragm seal 16 is directly carried opening of container, also can be between the circumference 19 of diaphragm seal 16 and opening of container, but mix the 4th base material that paste on the two sides is set, carries diaphragm seal 16 more thereon.
At this moment, but will have after the 4th base material of pasting on downward diaphragm seal two sides of grabbing the portion of pinching installs in the lid in this order, the lid that sealing film and the 4th base material are housed will be covered on the opening of container.In the inboard of this lid, diaphragm seal is being carried out the high-frequency induction heating under the state of the circumference crimping of opening of container.
Thus, the heat that utilizes high frequency to produce in the inside of the 3rd base material, between the circumference with diaphragm seal and vessel port (between following and the 4th base material of the 3rd base material of diaphragm seal top, between the circumference of the following and opening of container of the 4th base material) mutually stickup get up.
By such method also can produce with shown in above-mentioned Fig. 6 A and Fig. 6 B with the container that has the inner seal film of spline structure, its difference only is the 3rd base material 13 to be integrated on the diaphragm seal 16 in advance.
Here, the 4th base material is made of the material of Pastings such as thermoplastic base resin.As mentioned above, has stronger sticking strength between the circumference of the 4th base material and opening of container for well.
And, as mentioned above, polygon, star, the peristome of circle or the peristome of porous or mesh can be set on the 4th base material.
In the present invention, can use single face to have the film of sealant layer as the film that is used for first to the 3rd base material.As this film, for example can use the laminated film of following formation, that is, press the sealant layer that resin with hot adhibit quality constitutes on the surperficial upper strata of the substrate layer that constitutes by retractility film etc.And in order to be easy to paste on the container, the 3rd base material preferably uses the two sides to have sealant layer.
In order to give gas barrier property, as the described film aluminium oxide (Al that also can use evaporation 2O 3), monox (SiO x) etc. the ceramic-like thing vapor-deposited film of ceramic-like material, or metal level such as aluminium foil.At this moment, can stop seeing through of gases such as oxygen or aqueous vapor, so can improve the storage of content.
As the resin that constitutes sealant layer, polyethylene (PE), polypropylene (PP), ethylene-vinyl acetate copolymer polyolefin resins such as (EVA) are arranged, especially the face that pastes container of the 3rd base material preferably uses easy fissility material, and Kaifeng will become easy like this.
Can use single or multiple lift to make up as substrate layer by formations such as amilans such as polyethylene terephthalate alkide resins such as (PET), nylon.
Method as pasting base material has hot sticky subsides, super sonic stickup, high frequency stickup etc., wherein preferred hot sticky subsides.
The material or the thickness of first base material and second base material can be the same or different.For example, on layered product, for for form grab the portion of pinching and lamination the part and the part of grabbing beyond the portion of pinching of first base material and second base material, in order to reduce the poor of its thickness, can make the thickness of the thickness of first base material less than second base material.
Further, according to the present invention, because can make diaphragm seal as raw material, so can use the employed technology of Bag Making Machine with the long ribbon shape film.For example, as Fig. 2, shown in Figure 8, when overlapping onto two first base materials 1,11 on one second base material 2,12, can adopt following method, promptly, use a long ribbon shape film as the raw material of first base material 1,11, when transporting, raw material is divided into two be cut into two first base materials 1,11 after, again with doubling separately.
Again, in first base material that transports as folded membrane, when overlapping onto second base material, can use have a servomotor way roller is adjusted the transport direction of base material, thereby can control the lap position of two base materials.Action as servomotor can be as follows,, stylus printer (pitch) printed patterns is set on a certain base material among first base material and second base material that is, measures the position of this pattern by optical pickocff and come departing from of detection position.As optical pickocff, for example can use electro-optical tubes or CCD camera etc.The stylus printer printed patterns can be arranged on the part that constitutes diaphragm seal, also can be arranged on the part of removing by punching press.
When using diaphragm seal 6,16 of the present invention, also can adopt following structure as the inner seal film.Promptly, as Fig. 5, shown in Figure 11, when cover lid 8,18, grab the portion of pinching the 5, the 15th, recumbency, but by adjusting first base material 1,11 that constitutes the back side of grabbing the portion of pinching 5,15 and thickness and the elasticity that constitutes second base material 2,12 on the surface of grabbing the portion of pinching 5,15, when as Fig. 4, shown in Figure 10 when taking away lid 8,18, grabbing the portion of pinching 5,15 can erect naturally owing to the elasticity of self.
In addition, in diaphragm seal 6,16 of the present invention, by making first base material 1,11 that constitutes the back side of grabbing the portion of pinching 5,15 and color and the shape difference that constitutes second base material 2,12 on the surface of grabbing the portion of pinching 5,15, can make the user when seeing with diaphragm seal 6,16 sealed opening portions, find out the existence of grabbing the portion of pinching 5,15 easily, easily recognize to pinch and grab the portion of pinching 5,15 and just can break a seal.
Thus, can eliminate owing to do not see the existence of grabbing the portion of pinching 5,15, and attempt 5,15 o'clock diaphragm seal 6,16 is torn the inconvenience of being brought from outer edge 6a, 16a as not grabbing the portion of pinching.And, can also be designed on formation is grabbed second base material 2,12 on surface of the portion of pinching 5,15 (with the face of sealant layer opposition side), represent to tear the stripping direction with arrow etc.
