【附图说明】

图2为图1的层叠剥离容器1的口部9及外气导入孔15附近的放大剖面图。
图3为阀部件5的立体图。
图4为表示内层13的结构的剖面图。
【具体实施方式】
以下说明本发明的实施方式。以下示出的实施方式中的各种特征事项可以相互结合。并且，各特征独立地使发明成立。
如图1～图3所示，本发明的一个实施方式的层叠剥离容器1具备容器主体3和阀部件5。容器主体3具备容纳内置物的收容部7、从收容部7排出内置物的口部9。
如图2所示，容器主体3在收容部7以及口部9具备外层11和内层13，由外层11构成外壳12，由内层13构成内袋14。随着内置物的减少内层13从外层11剥离，内袋14从外壳12剥离而收缩。应予说明，有时候在收容部7容纳内置物之前进行将内层13从外层11剥离的预备剥离工序。此时，通过在预备剥离之后，向收容部7内吹入空气或者容纳内置物，使内层13与外层11接触。并且，随着内置物的减少内层13从外层11离开。另一方面，在不进行预备剥离工序的情况下，排出内置物时内层13从外层11剥离而从外层11离开。
口部9设有卡合部9d，卡合部9d可以和具有止回阀的盖帽卡合。盖帽可以是以压盖式安装的，也可以是以螺杆式安装的。
如图1～图2所示，收容部7设有凹部7a，凹部7a设有外气导入孔15。外气导入孔15是仅设在外壳12的贯通孔，连通外壳12与内袋14之间的中部空间21和容器主体3的外部空间S。并且，设置从凹部7a向口部9方向延伸的空气流通槽7b，使凹部7a不被收缩膜密封。
如图2～图3所示，阀部件5具备插入外气导入孔15且相对于外气导入孔15可滑动的轴部5a、设置于轴部5a的中部空间21侧且比轴部5a剖面积更大的盖部5c、设置于轴部5a的外部空间S侧且防止阀部件5进入中部空间21的卡止部5b。
盖部5c以压缩外壳12时使外气导入孔15实质上闭塞的方式构成，成为随着接近轴部5a截面积小的形状。并且，卡止部5b构成为外壳12被压缩后复原时空气可导入中间空间21。若压缩外壳12，则中间空间21内的压力变得高于外压，中间空间21内的空气从外气导入孔15漏到外部。由于该压力差和气流，盖部5c向外部气体导入孔15移动，盖部5c闭塞外部气体导入孔15。由于盖部5c为越靠近轴部5a横截面积越小的形状，因此盖部5c容易嵌入外部气体导入孔15而闭塞外部气体导入孔15。
若在此状态下进一步压缩外壳12，中部空间21内的压力升高，结果内袋14压缩，内袋14内的内容物被排出。并且，若解除对若外壳12的压缩力，则外壳12会凭借自身的弹性而复原。此时，盖部5c离开外气导入孔15，外气导入孔15的闭塞被解除，外气被导入中间空间21内。另外，为了防止卡止部5b塞住外气导入孔15，在卡止部5b设置流通路5d，即使在卡止部5b抵接于外壳12的状态下，外气也可通过流通路5d和外气导入孔15而导入中间空间21内。
接着，对容器主体3的层结构进行更详细的说明。容器主体3具备外层11和内层13。
外层11例如由低密度聚乙烯、直链状低密度聚乙烯、高密度聚乙烯、聚丙烯、乙烯-丙烯共聚物及其混合物等构成。外层11可以是多层结构。例如可以是用原生材料夹持再生层的两侧而成的构成。这里，所谓再生层，是指循环使用容器成形时产生的毛边而得到的层。另外，外层11以复原性高的方式形成为壁厚大于内层13。外层11优选为由丙烯和其他单体之间的无规共聚物组成。与丙烯共聚合的单体可以是相比于聚丙烯的均聚物，提高了无规共聚物的耐冲击性的化合物，优选为乙烯。丙烯与乙烯的无规共聚物中，乙烯的含量优选为5～30Mol％。无规共聚物的重均分子量优选为10～50万，更优选为10～30万。并且，无规共聚物的拉伸模量优选400～1600MPa，更优选1000～1600MPa。因为，拉伸模量在此范围时，具有特别优良的形状复原性。若容器过硬，则导致容器的使用感变差，因此，无规共聚物可以混合直链状低密度聚乙烯等柔软材料构成外层11。
如图4所示，内层13具备作为最内层的内侧EVOH层13a、作为最外层的外侧EVOH层13b、设于两者之间的粘合层13c。
内侧EVOH层13a是由乙烯－乙烯醇共聚物(EVOH)树脂构成的。构成内侧EVOH层13a的EVOH树脂的乙烯含量E1为34mol％以下，优选为31mol％。此时，特别抑制向容器内面的香味成分的吸附。乙烯含量E1为34mol％以下时，预想到内侧EVOH层13a的刚性过高而引起内袋14的收缩性变差的问题，内置物含有水分(更具体而言，主成分为水)的情况下，发现由于内侧EVOH层13a吸水而变软，抑制内袋14的收缩性变差而耐用。并且，乙烯含量E1为34mol％以下时，内侧EVOH层13a不吸水的状态下，由于内侧EVOH层13a的刚性大，内层13整体的刚性也变大，因此存在内袋14易于从外壳12预备剥离的优点。也就是说，使乙烯含量E1成为34mol％以下，可获得在填充内置物之前易于被预备剥离且填充内置物后易于收缩的内袋14。
乙烯含量E1过小时，即使内侧EVOH层13a吸水，刚性也不会充分变低，因此乙烯含量E1优选为26mol％以上。乙烯含量E1具体而言例如为26、27、28、29、30、31、32、33、34mol％，也可以是这里例示的数值中的任意2个数值之间的范围内。
因EVOH树脂相对来说刚性高，将EVOH树脂使用为内层13的材料时，通常添加柔软成分于EVOH树脂从而提高柔软性。然而，添加柔软成分于构成作为内层13的最内层的内侧EVOH层13a的EVOH树脂时，由于香味成分易吸附于内侧EVOH层13a，构成内侧EVOH层13a的EVOH树脂中，柔软成分等杂质的内容比例优选为5质量％以下、更优选为1质量％以下、特别优选为0.1质量％以下。应予说明，杂质的含有方式可例举，杂质混合于EVOH树脂的方式、杂质引入于EVOH树脂的聚合物骨架的方式。
实质上不包含柔软成分的EVOH树脂中，已知弯曲模量和乙烯含量大约呈现式1的关系。弯曲模量可根据ISO178的试验方法进行测定。试验速度为2mm/min。
(式1)弯曲模量(MPa)≒6600－86×乙烯含量(mol％)
EVOH树脂包含柔软成分时，弯曲模量将大幅小于根据式1求得的值。构成内侧EVOH层13a的EVOH树脂优选为不含有柔软成分等杂质，构成内侧EVOH层13a的EVOH树脂的弯曲模量优选满足式2。式2的α为常数，例如为0.8。α具体而言例如为0.8、0.81、0.82、0.83、0.84、0.85、0.86、0.87、0.88、0.89、0.9、0.91、0.92、0.93、0.94、0.95、0.96、0.97、0.98、0.99、1，也可以是这里例示的数值中的任意2个数值之间的范围内。
(式2)弯曲模量(MPa)≥α×(6600－86×乙烯含量(mol％))
EVOH树脂因刚性大，若内侧EVOH层13a过厚，吐出内置物时将产生内袋14难以顺利收缩的问题。并且，若内侧EVOH层13a过薄，内侧EVOH层13a不均匀形成而引起粘合层13c暴露于容器内面，针孔易形成于内侧EVOH层13a的问题。从这些观点考虑，内侧EVOH层13a的厚度为10～50μm。此厚度优选为21μm以上。内侧EVOH层13a的厚度为21μm以上时，优选可充分抑制内置物的成分渗透至邻接内侧EVOH层的层。此厚度具体而言例如为10、15、20、21、25、30、35、40、45、50μm，也可以是这里例示的数值中的任意2个数值之间的范围内。
外侧EVOH层13b与内侧EVOH层13a同样有乙烯－乙烯醇共聚物(EVOH)树脂构成。外侧EVOH层13b的厚度并无特别限定，例如为10～50μm。外侧EVOH层13b过薄时，内层13的阻气性不充分，外侧EVOH层13b过厚时，内层13的柔软性不充分，产生吐出内置物时内袋14难以顺利收缩的问题。此厚度具体而言例如为10、15、20、21、25、30、35、40、45、50μm，也可以是这里例示的数值中的任意2个数值之间的范围内。
外侧EVOH层13b/内侧EVOH层13a的厚度之比并无特别限定，例如为0.5～2。此比具体而言例如为0.5、0.6、0.7、0.8、0.9、1、1.1、1.2、1.3、1.4、1.5、1.6、1.7、1.8、1.9、2，也可以是这里例示的数值中的任意2个数值之间的范围内。并且，作为内层13的最外层设置外侧EVOH层13b，从而可提高自外层11的内层13的剥离性。
构成外侧EVOH层13b的EVOH树脂的乙烯含量E2例如为25～50mol％。乙烯含量E2优选与乙烯含量E1相同或大于此。其理由为，(1)需要将乙烯含量E1成为小的值从而抑制香味成分吸附于内侧EVOH层13a，但由于外侧EVOH层13b不接触于内置物无需将乙烯含量E2小到乙烯含量E1的程度、及(2)由于乙烯含量E2越小外侧EVOH层13b的柔软性越容易降低，乙烯含量E2优选与乙烯含量E1相同或大于此。乙烯含量E2具体而言例如为25、26、27、28、29、30、31、32、33、34、35、40、45、50mol％，也可以是这里例示的数值中的任意2个数值之间的范围内。在此，从氧阻隔性的观点考虑，乙烯含量E2优先偏小，乙烯含量E1及E2两者均为32mol％以下为优选。特别是，乙烯含量E1及E2两者均为29mol％以下为优选。
外侧EVOH层13b的EVOH树脂的弯曲模量优选小于内侧EVOH层13a的EVOH树脂。外侧EVOH层13b的EVOH树脂优先添加柔软成分降低弯曲模量。外侧EVOH层13b的EVOH树脂的弯曲模量例如为1800～3000MPa，具体而言例如为1800、1900、2000、2100、2200、2300、2400、2500、2600、2700、2800、2900、3000MPa，也可以是这里例示的数值中的任意2个数值之间的范围内。特别是，考虑到氧阻隔性及内袋的收缩性，优选使外侧EVOH13b的厚度厚于内侧EVOH13a，且通过向外侧EVOH13b添加柔软成分等，使外侧EVOH13b的弯曲模量小于内侧EVOH13a的弯曲模量。并且，考虑到内袋的收缩性，优选内侧EVOH13a的弯曲模量满足上述式2，且使外侧EVOH13b的弯曲模量不满足上述式2。此时，式2的常数α为0.8。
粘合层13c是配置于内侧EVOH层13a和外侧EVOH层13b之间的层，例如为添加有对上述聚烯烃导入了羧基的酸改性聚烯烃(例:马来酸酐改性聚乙烯)的层或者乙烯乙酸乙烯酯共聚物(EVA)。粘合层13c的一个例子为低密度聚乙烯或直链状低密度聚乙烯与酸改性聚乙烯的混合物
本实施方式也可以通过以下的方式实施。
·在上述实施方式中，通过阀部件5在外气导入孔15的边缘和阀部件5之间的间隙移动从而进行开闭，使阀部件5构成为可开闭外气导入孔15。也可构成为在阀部件本身设置貫通孔和可开闭的阀，通过此阀的作用开闭貫通孔，从而开闭外气导入孔15。并且，也可省略阀部件5，吐出内置物时使用手指等闭塞外气导入孔15。
·也可将外气导入孔15设于口部9，使用盖帽，其具有连通于外气导入孔15的止回阀。

2.层叠剥离容器的评价

(式3)剩余指数＝(总剩余量1/总剩余量2)
总剩余量1:对于吐出自实施例·比较例的层叠剥离容器的醋的总剩余量
总剩余量2:对于吐出自玻璃瓶的醋的总剩余量
◎:剩余指数为0.9以上
○:剩余指数为0.8以上、小于0.9

＜考察＞
将香味成分的维持性及内袋收缩性的评价结果示于表1。如表1所示，所有的实施例·比较例呈现良好的内袋收缩性。并且，所有的实施例呈现良好的香味成分的维持性，但比较例中香味成分的减少相对来说较大。由此，证实了乙烯含量E1为34mol％以下的情况下，大幅抑制了香味成分的减少。并且，通过比较实施例1～2和实施例3，证实了乙烯含量E1为31mol％以下的情况下，进一步抑制了香味成分的减少。
