The present invention relates to a kind of bag-making method, more specifically, the present invention relates to a kind of by melting bonding to guarantee that the fusing adhesive portion between spout member and the bag unit has the bag-making method that the better fluid sealing is made bag part to a spout member and a bag unit of making by flexible membrane of making by synthetic resin.In addition, the invention still further relates to a kind of in the container of making by above-mentioned bag-making method, fill behind transfusion solution or the blood and the containers for medical use that uses.
The present invention requires the priority of the Japanese patent application No.2002-314252 of proposition on October 29th, 2002.
Background technology
In recent years, the containers for medical use of being made by synthetic resin commonly used replaces the containers for medical use made by glass.The synthetic resin containers for medical use comprises container of making by blow moulding and the container of being made by a film material or a sheet material (following film material and sheet material all are called " film material ") by blowing moulding (inflationmolding) or T mould casting method (T-die casting).Wherein, increasing by the container (to call " film bag " in the following text) that the film material is made, because the film bag is thin and make container thickness even, thereby and to use the back volume to dwindle the discarded object that is produced less, and the speed of emitting of liquid containing thing to the last all can keep constant when transfusion.In the film bag, fix an oral area member so that can fill or emit contents by heat-sealing, as shown in Figure 1, this spout member is the hollow column of being made by synthetic resin with 3D shape.Under many circumstances, the cross section of spout member is the circular or oval of a hollow.
Spout member is fixed on the film material, the member of 3D shape must be fixed on the two-dimensional plane film material exactly, thereby as shown in Figure 2, between the fusing adhesive portion of the A of film material shape structural portion and spout member, produce a gap 22 (hereinafter referred to as " A shape structural portion gap ") sometimes, thereby can cause the leakage of liquid containing thing.Especially be under the situation of 100 μ m or more thick film material at thickness, although may differently because of the shape of spout member change to some extent, consistent but described film material all can be out of shape when sealing with the shape of spout member, and the part that a sealing-in forms is thrown off because of the recovery stress of film material sometimes.In addition, melt when bonding when by a sealing mold spout member and film material being clipped in the middle, this film material will be subjected to a bigger tensile stress so that consistent with the shape of spout member, and can there be the danger that makes this film material attenuation or form the hole on the film material in this.
For preventing film material distortion or forming the hole, known a kind of like this method: promptly use the adhesive refractory layer that on the film material, superpose, to form the laminated film material of hear resistance enhancing.But medical field is not preferably used adhesive, because adhesive stripping sometimes.Therefore, people are close bonding but can not comprise that the adhesive technology that produces the gap between the bag unit of single or multiple lift film material has carried out various researchs at spout member and to not causing material dissolves and can forming liquid.
With regard to the container that successfully solves A shape structural portion clearance issues, proposed a kind ofly by with bag unit and the bonding container that obtains of spout member, as shown in Figure 3, the left and right sides of the fusing adhesive portion of this spout member is provided with outward extending strip 23.
By a container body and spout member-its fusing adhesive portion left and right sides are provided with outward extending strip-bonding concrete example of making the method for container and comprise: use preheating anchor clamps to make the spout member that has been provided with strip on it, then this spout member is heat sealed to the method (seeing patent document 1) on the infusion bag;
The surface of one opening plug was melted with high 15 to the 80 ℃ temperature of the fusing point of a ratio open plug material before this opening plug contact membranes material or sheet material, form simultaneously width and be 0.2 to 0.3mm the bonding protuberance of fusion in these opening plug both sides, then from the direction of symmetry with two film materials or sheet extrusion to the opening plug so that described film material or sheet material fusion are bonded to this opening method (seeing patent document 2) beyond the Great Wall;
The position of symmetry is provided with jut on the outer circumferential surface of a hollow column, thereby on the vertical axis direction with this hollow column separated into two parts, under the situation that the connecting portion of this hollow column narrows down, thereby the softening described jut of heating is contiguous to sheet material the method (seeing patent document 3) on described jut and the hollow column then under soft state;
One expansion tube is heat sealed on the mouthpiece with fin-shaped projection that is formed by metal die, thereby makes the method (seeing patent document 4) of bag part; And
Before the fusing of opening plug is bonded to film material or sheet material, utilizing temperature is that 600 ℃ to 800 ℃ the radiant heat of heater is at the superficial layer from the softening temperature of opening plug fusing adhesive portion material this opening plug fusing adhesive portion of heating in than the high 13 ℃ temperature range of the fusing point of this material, then by the opening plug that heated from the both sides extruding about the fin form metal mould of opening plug symmetry to form the fin-shaped strip beyond the Great Wall at this opening, the opening plug that then will still be in heating status inserts between film material or the sheet material, thereby the opening plug is melted the method (seeing patent document 5) that bonds on film material or the sheet material by heat seal die.
These methods are: be manufactured on the spout member that its left and right sides of waiting to melt the part that bonds to the film material is provided with outward extending strip in advance, then this spout member bonded to bag unit.This method not only needs one to form the unnecessary step of strip, and can go wrong when forming strip, as the size fluctuation of strip, about two strip sizes inconsistent and adhere to carbide fragment from the strip shaping dies.In addition, preformed strip may be out of shape, and for example shrinks, twists or come off.And, owing to when injection moulding, result from the release of the residual stress of spout member fusing adhesive portion, heating is easy to make the spout member distortion, therefore when spout member is bonded to bag unit, can not accurately adjust the position of spout member, bag unit and sealing mold, thereby cause bonding undesirable.Therefore, need improve so that prevent A shape structural portion generation gap more up hill and dale.
Especially under the situation of diameter above the large scale spout member of 10mm, the situation of attenuation of film material and generation aperture appears through regular meeting.

At spout member 1 cross section is under the situation of circle, and its diameter is 10 to 30mm, and the thickness of this spout member is 0.5 to 3mm, highly is about 20 to 80mm.
The example that is used for the synthetic resin of spout member comprises: mylar, for example PETG and polybutylene terephthalate (PBT); Polycarbonate resin; And polyolefin resin, for example polypropylene and polyethylene.Wherein, polyolefin resin preferably, the blending resin of more preferably single resin or polyvinyl resin, for example high density polyethylene (HDPE), LLDPE, high-pressure process low density polyethylene (LDPE) and the polyethylene made with metallocene catalyst.The preferred use and the identical resin of flexible membrane that constitutes bag unit.
Spout member 1 can comprise multilayer.The outermost layer that particularly preferably will the resin identical be used for spout member with flexible membrane, and the resin of a hear resistance and the outer floor height of ratio of rigidity is used for innermost layer, this is because the distortion of spout member when preheating can be subjected to more inhibition, when the entry needle mistake is thrust the inside of spout member, can prevent that this entry needle from stinging the outside internally on the side surface of spout member simultaneously.
In bag-making method of the present invention, melting bonding is to carry out after spout member 1 preheating that will be made by synthetic resin.Almost spout member 1 is all made by injection moulding in all cases, the inventor has been found that: produce when injection moulding and be limited in residual stress in the spout member and discharges when preheating and spout member is out of shape, therefore when by a sealing mold 5 with the spout member 1 that is out of shape and bag unit 2 when pinched together, (spout member) becomes inhomogeneous with the contacting of film material of bag unit 2, therefore produces local contact or gap before fusing is bonding between the film material of spout member 1 and bag unit 2.More specifically, the relative position relation between spout member 1, bag unit 2 and the sealing mold 5 is owing to the distortion of spout member changes, thereby the resin of spout member can not be filled A shape structural portion gap in some cases.For between spout member 1, bag unit 2 and sealing mold 5, stably setting up a preferred relative position relation, should prevent that spout member 1 is out of shape when preheating.The inventor finds: carry out preheating but the softening spout members that just can prevent in end 11 of spout member are out of shape, therefore spout member 1, bag unit 2 and sealing mold 5 can be adjusted to exact position separately, thus fusible bonding spout member 1 and bag unit 2 but do not produce A shape structural portion gap.
Usually, melt bonding spout member 1 and bag unit 2 like this: the fusing adhesive portion of this spout member is defined as on this spout member section except top 13 (will fix a rubber stopper on it), and it is softening up to described fusing adhesive portion to heat this spout member.But, for suppressing the distortion of spout member 1, thereby be not heated not softening if the bag side end 11-of spout member is an end of spout member and the top 13 of this spout member, then can prevent the spout member distortion on the whole, thereby improve the positional precision of spout member, bag unit and sealing mold, improve contact performance, realize melting bonding uniformly and form strip, thereby the gapless fusing of A shape structural portion that can be implemented between bag unit and the spout member is bonding in spout member fusing adhesive portion.According to conventional methods, the end of spout member also is heated, and by-as the case may be-and be heated to a temperature that is higher than film material fusing point, therefore, when sealing-in spout member 1 and bag unit 2, make the attenuation of film material near the end at spout member easily.This problem also can solve by above-mentioned technology.Prevent the local attenuation of film material, thereby improved the bag intensity that comes off of container body.
" softening (softening) " used herein is meant a kind of like this state: promptly resin is softened by surperficial fusible the bond to degree that this film material on simultaneously form strip of sealing mold via the spout member fusing adhesive portion of film material extruding.To not softening spout member end estimate confirm so that before its surface state and the preheating state of oral area component surface identical.In this example, before pushing by sealing mold on the border visible of spout member end and spout member fusing adhesive portion line of demarcation clearly.Make spout member reach the macroscopic state in described line of demarcation by preheating, just can realize purpose of the present invention.
When preheating, use a hot-die directly heating or by from a thermal source for example the radiant heat of ring heater or the radiant heat of far infrared heat, and the surface temperature of the fusing adhesive portion 12 between spout member and the bag unit (being the fusing adhesive portion of spout member) is set at a softening temperature of synthetic resin that can be used in spout member.
In these heating means, consider to connect exterior material and simplify machine construction that it is favourable heating by radiant heat, therefore preferred this method.For preheater 3, the preferred ring heater that uses shape with the end 11 that can not heat spout member.Fig. 4 A and Fig. 4 B respectively are the cutaway view of an example of the spout member that carries out preheating by a ring heater 31 that is covered by heat-barrier material 33.By 34 places, non-heating part spout member 1 is installed at ring heater, or thereby the hollow space by a supporting member being put into spout member 1 from the top of Fig. 4 A and 4B supports spout member at least two parts and arranges with the accurate space that keeps spout member and ring heater, also the gap between spout member 1 and the preheater 3 can be remained on a higher precision.In addition, if rotate spout member, then can make the heat that received from preheater 3 upwards become even whole week in this spout member fusing adhesive portion 12.If make the heat that is applied in the preheating step on the spout member fusing adhesive portion 12 stable and even, then more suppressed the distortion of this spout member 1, thereby can carry out the position adjustment to spout member, bag unit and sealing mold more accurately.
Heating-up temperature must be enough high so that form strip on this spout member when by film material extruding spout member in the fusing bonding step.Under the situation of utilizing radiant heat to heat, can select suitable heating-up temperature according to the constituent material of gap between thermal source and the spout member surface or spout member, although but may change according to the constituent material of spout member is different, preferred thermal source is set at 500 to 750 ℃ and carry out 8 to 13 seconds heating.If the temperature of spout member fusing adhesive portion 12 is too high, then may produce the catabolite of synthetic resin or flow deformation (flowdeformation) occur, in addition, the end of spout member may be softened because of the Temperature Influence of this spout member fusing adhesive portion, therefore must avoid temperature too high.
More particularly, for the softening but end 11 of softening this spout member not of the fusing adhesive portion 12 that makes spout member, for example, the end 11 that makes spout member is from the thermal source outstanding 0.5mm or more at least of ring heater for example, preferred outstanding 0.8mm or more, thereby the end 11 that can avoid spout member effectively is subjected to photothermal effect and softens, and rigidity reduces and distortion owing to be heated therefore can to prevent spout member on the whole.
Shown in Fig. 4 B, other example comprise a kind of use heat-proof device for example thermal insulation board 32 prevent that the end 11 of spout member is subjected to the photothermal method from thermal source, and a kind of unshowned cooling frame that has a circular cap shape recess by the end abutment one that makes spout member to be to cool off the method for this spout member end, and the end of this spout member can enter described recess.In addition, shown in Fig. 5 A and 5B, purpose of the present invention also can realize by using such spout member: promptly from a length L of the bottommost 14 (making progress) of spout member as 5mm or still less-be preferably the diameter that 1 to 5mm section reduces this spout member end 11 increase the distance of this spout member end 11 so that compare to thermal source with the fusing adhesive portion 12 of spout member.
Thereby extruding with the fusing bonding step that the spout member fusing bonds on the bag unit is: the spout member of preheating inserts the opening of bag unit and pushes them by sealing mold and bonds to this opening with the fusing adhesive portion fusing with spout member.An example of fusing bonding step is described below with reference to Fig. 6.In the example below, will insert in the opening of bag unit by the spout member of column supporting, thereby bag unit decompression and fusing are bonded on this spout member.When the diameter of oral area member surpassed 10mm, this method of being undertaken by decompression was more effective.A kind of similar method has been described in the patent document 6.
In order to help keeping spout member, as shown in Figure 6, a column 4 is inserted the hollow space of the cylindrical mouth member 1 of hollow.
The external diameter of this column is slightly less than the internal diameter of spout member, and has a hole to penetrate its far-end in this column.The shape of the far-end of this column (air pump orifice 43) can adapt to crooked film material, is the shape that an area of section reduces gradually towards the far-end of column.
This area of section is from the far-end 5mm of distance column or more and begin to reduce gradually than the position of the more close described far-end in end 11 of spout member simultaneously.Column is inserted so that the far-end 43 of this column is given prominence to 5mm or more at least from the end 11 of spout member.Extract the interior air of bag unit out so that its decompression-this will be explained below, thereby it is tightr that column 4 is contacted with bag unit.In addition, if column 4 also is used as the stationary fixture of spout member 1 in preheating step, then can play the effect that further prevents the spout member distortion, but, because the machine construction complexity-need consider the difference of sealing-in time (time period that sealing mold pushes) and preheating time when that is to say this machine construction of structure, so it is complicated that this equipment becomes slightly, thereby cost is improved.
If desired, can make its decompression by the air that pressure-reduction outlet 42 is extracted out in the bag unit, to strengthen tight contact of column 4 and 2 of bag units.Be the opportunity of reducing pressure: before sealing mold 5 closes or in sealing mold 5 closures.Therefore bag unit is fixed by the depressurization, and can prevent effectively because for example film material attenuation that the heat effect of sealing mold 5 occurs or in the problem of the border of fusing adhesive portion and non-melt adhesive portion generation aperture.In addition, bag unit 2 contacts by decompression securely with spout member 1, thereby the film material is bent and fixes so that consistent with spout member end 11 shapes at column support 41.In addition, because the temperature of spout member end is low, therefore can suppress attenuation effectively.
Melt the fusing adhesive portion 21 that bonds to bag unit by sealing mold shown in Figure 75 squeeze bag unit 2 and spout member 1 with fusing adhesive portion 12 with spout member.The temperature of sealing mold 5 is higher 10 ℃ or more than the fusing point of film material (bag unit resin), and under the situation that the film material is made by polyvinyl resin, this temperature is 110 to 170 ℃, is about 1 to 3 second and melt the bonding time.After preheating, preferably lack as much as possible, but due to the limitation by the production apparatus, this time period is generally 1 to 4 second up to the time period of pushing with sealing mold 5.If should the time period surpass 4 seconds, then the surface temperature of spout member fusing adhesive portion descends, thereby the sealing strength between spout member 1 and the bag unit 2 is not enough easily.In fusing when bonding,, then form strip easily if the bight of sealing mold has as shown in Figure 7 a roundlet angle R.
The shape of sealing mold 5 comprises the part of semi-circular cross-section peace, and the connecting portion of the part of semi-circular cross-section peace promptly the A shape structural portion between spout member 1 and film material be formed with fillet R.R is 0.2 to 2mm, is preferably 0.3 to 1.7mm.If R is excessive, then can not prevent the formation in A shape structural portion gap, and if R is too small, then be easy to generate the problem that for example the film material is scratched or formed strip is not enough.The diameter of semi-circular cross-section be slightly less than that diameter by spout member fusing adhesive portion 12 adds film material thickness and size.And sealing mold 5 is preferably designed so that melting and does not heat when bonding from the bottommost (making progress) of the spout member end section of 0.5mm at least, to avoid making the attenuation of film material.The example of this sealing mold 5 comprises that section that its shape can be at least bottom side (making progress) length from the spout member end 0.5mm is controlled at a mould that is lower than under the temperature of fusing point of film material.Preferred sealing mold is given prominence to the mould of length M for made spout member 1 as shown in Figure 8 from this sealing mold 5.Length M is preferably 0.5mm or longer.Because this length be not extruded at the far-end of spout member and the film material between the mould, thereby described film material is difficult for attenuation.Like this, this film material can become the part of containers for medical use shown in Figure 96.
In this example, in the bag unit decompression, melt bonding spout member and bag unit, but also can realize effect of the present invention like this: promptly softening spout member 1 and bag unit 2 melt bonding spout member fusing adhesive portion 12 at Qi Chu, the end 11 that prevents spout member simultaneously is softening when preheating, pushes spout member 1 and bag unit 2 then but does not use column.
In the spout member 1 that is heated in preheating step of the present invention, thereby the residual stress that produces during injection moulding is eliminated and has prevented distortion, so spout member 1 and bag unit 2 all can be installed to accurate position with respect to sealing mold 5.Because it is bonding that described parts are melted under this pinpoint state, the softening resin that therefore is extruded to the spout member fusing adhesive portion 12 on the flexible membrane can form a strip that has stable shape and extend in A shape structural portion gap.
The strip suitable dimensions is: thickness is about 50 to 200 μ m, and length is about 0.1 to 2mm.According to the present invention, spout member can have the strip of this size, by melting bonding this spout member, can stably make no A shape structural portion gap and do not produce leak of liquid have spout member the bag part.
After melting bonding spout member, will melt bonding portion by a cooling frame and be clipped in the middle.Owing to prevented that spout member is out of shape when preheating, so with to carry out clamping by sealing mold similar, being held material when carrying out clamping by cooling frame also can be accurately and location stably, thus stably molded strip.
If reduce pressure in the bag unit, then needn't reduce pressure again.Melt bonding under decompression state and cooling, the film material will closely contact the mouth of pipe (nozzle) and be fixed with consistent with this orifice configuration until by film material sealing mold described film material being bonded to and cooling with the spout member fusing.Described fusing is bonded under the state that restriction film material moves freely to be carried out, thereby has played the softening film material of the fusing that can not stretch like this and can not make the fusing adhesive portion of spout member and the effect of the border attenuation of non-melt adhesive portion.
Example
The spout member that forms by the equivalent blend composition of high density polyethylene (HDPE) and LLDPE by injection moulding manufacturing one with circular cross section, the diameter of this spout member is that 17mm, internal diameter are 13mm, and the fusing adhesive portion of this spout member and end portion thickness are 2mm.
Forming width by blowing moulding is the tubular linear low density polyethylene films material of 140mm, and it is long to be cut into 300mm.By heat-sealing a cut is sealed, and with the fusing adhesive portion of another cut as film material opening.On the other hand, one ring heater is inserted spout member and the center of this heater and the center-aligned of spout member were heated 10 seconds then, and 1mm can be given prominence to from this Department of Radiation in the end that this heater design becomes the Department of Radiation surface temperature can reach 700 ℃ and spout member.After being installed to hollow column in the spout member, immediately this spout member is inserted in the fusing adhesive portion of the bag unit that as above prepares, aspirate by a vavuum pump simultaneously so that reduce pressure in this bag unit, then 140 ℃ down by sealing-in modules with described fusing adhesive portion clamping 2 seconds.Subsequently, will melt the adhesive portion clamping 3 seconds, after vacuum state is removed, hollow column be pulled out the bag part that has spout member with formation with cooling frame.
Prepare 100 this bag parts that have spout member, in each bag part, charge into 500ml water and jam-pack, then from the described bag of external compression part so that its internal pressure reaches 0.07MPa, kept then 5 minutes.Can see that all bag parts that have spout member all do not leak.
Though above illustrated and shown the preferred embodiments of the present invention, should be appreciated that these only are examples of the present invention and do not have restricted.In addition, under the situation that does not break away from the spirit or scope of the present invention, can add, omit, substitute and other modification.Therefore, the present invention is not considered as being limited by the foregoing description, and limited by the scope of appended claim.
