Abstract

在用于由药包片材按每次配药量来包装药剂的药剂包装机中，即使是老人或小孩也能够简单地打开。药剂包装机使用带状的药包片材(20)，通过制造在内部收纳有药剂的状态下是连续的、在服用时分离的多个分包袋来包装药剂。药包片材(20)的原材料是含有聚对苯二甲酸乙二醇酯片材(PET)或二轴延伸聚丙烯片材的带状的透明复合塑料片材，而且在聚对苯二甲酸乙二醇酯片材或二轴延伸聚丙烯片材上形成微细的疵点。

Description

药剂包装机
技术领域
本发明涉及用于在医院或药店等中，用药包片材按每次配药量来包装基于医生的处方条而配好的药剂的药剂包装机，及药剂包装机使用的药包片材或分包袋。
背景技术
在现有技术下，在按照处方条发给患者配好的药剂的情况下，通过自动药剂包装机等将每次给药所需的药剂分包在同一分包袋内来进行给药，以使患者自身不需要每次都组合不同的药剂服用(参照专利文献1)。
作为该药包袋的材料，通用的是易于自动药剂包装机内的操作、内部可视性高易于配料检查、分包袋的开封性(打封容易程度)等良好的包装片材(玻璃纸)或最近常用的聚乙烯层压赛璐芬纸、聚乙烯层压玻璃纸等的包装片材。
专利文献1
特开平8-11805号公报
可是，因为赛璐芬等价格很高，近来逐渐使用能够接触食品并确认了安全性的聚丙烯或聚对苯二甲酸乙二醇酯等作为药包袋的材料。
可是，在以聚丙烯或聚对苯二甲酸乙二醇酯等作为原材料来制作分包袋的情况下，虽然药剂分包时的操作性与配料检查的容易程度与现有的使用玻璃纸或赛璐芬纸等的情况相比毫不逊色，但老人或孩子在打开分包袋并服药的情况下，难于知道在哪个位置打开及怎样打开，在其任意操作的方面产生了问题。
本发明为了解决相关问题而提出，其目的在于：在用于由药包片材按每次配药量来包装基于医生的处方条而调剂的药剂的药剂包装机中，即使是老人或小孩也能够简单地打开，及提供药剂包装机使用的药包片材或通过包装机形成的分包袋。
发明内容
即，本发明的药剂包装机使用带状的药包片材，通过制造在内部收纳有药剂的状态下是连续的、在服用时分离的多个分包袋来包装前述药剂，其特征是：药包片材的原材料是含有聚对苯二甲酸乙二醇酯片材或二轴延伸聚丙稀片材的带状的透明复合塑料片材，而且在聚对苯二甲酸乙二醇酯片材或二轴延伸聚丙稀片材上形成微细的疵点。
技术方案2的药剂包装机使用带状的药包片材，通过制造在内部收纳有药剂的状态下是连续的、并在服用时分离的多个分包袋来包装前述药剂，其特征是：药包片材的原材料是含有聚对苯二甲酸乙二醇酯片材或二轴延伸聚丙稀片材的带状的透明复合塑料片材，而且两侧端缘部在对折时形成为相互重合的波状或锯齿状，相互对合热熔敷。
技术方案3的药剂包装机的特征是在技术方案2中，在药包片材的聚对苯二甲酸乙二醇酯片材或二轴延伸聚丙稀片材上形成微细的疵点。
此外，技术方案4的药剂包装机的特征是在技术方案1、技术方案2或技术方案3中，对带状的药包片材的侧端缘部进行对合热熔敷，而且通过在与该药包片材的长度方向垂直的方向上热熔敷规定的宽度来制作前述分包袋，并且该分包袋的结构是在内部收纳有药剂的状态下是连续的、在服用能够分离。
根据技术方案1～技术方案4的药剂包装机，药包片材在例如药剂分包时的操作性或配料检查的容易性等方面，与以往使用玻璃纸或赛璐芬纸等的情况相比毫不逊色，由于是以所希望的规定宽度进行切断加工并卷取，所以也适用于以往的自动药剂包装机。即，没有必要制造或购入新的或专用的自动药剂包装机。
此外，因为即使是老人或小孩也能够简单地空手撕开分包袋，所以能够将分包后的药剂不沿熔敷部而沿对折部分(未熔敷部)导引，由此，即使是粉剂这样的微细粒子也不会残留并能够可靠地服用，得到实效性优良的作用效果。
技术方案5的药包片材是用于制造在内部收纳有药剂的状态下是连续的、在服用时分离的多个分包袋的带状片材，其原材料是塑料片材，而且两侧端缘部在对折时形成为相互重合的三角形状的切口，相互对合热熔敷，所以在取出收纳于分包袋内的药剂时，能够沿塑料片材的切口来撕开分包袋。由此，例如即使是与以往使用的聚乙烯层压赛璐芬纸、或聚乙烯层压玻璃纸等的包装纸相比而难于撕开的塑料片材构成的分包袋，也能够从所希望的切口位置简单地撕开。所以，即使是老人或小孩也能够简单地空手撕开分包袋。
进而，技术方案6的药包片材的特征是在技术方案5中，在对折后，两侧端缘部的前述切口相互大致吻合，所以在设于分包袋的两侧端缘部的切口部分易于集中切入力。由此，能够以比较弱的力从切口部分撕开分包袋。所以，即使是老人或小孩、特别是手的力气较小的病人，也能够从塑料片材对折所得的分包袋的两侧端缘部的切口简单地撕开。
此外，技术方案7的药包片材的特征是在技术方案5中，在对折后，两侧端缘部的前述切口相互错开，所以在从设于药包片材的两侧端缘部的切口部分撕开分包袋时，能够错开分包袋被撕开的端部。由此，能够撕开分包袋并从错开的端部容易地打开该分包袋。所以，能够极其简单地取出分包袋内的药剂。
技术方案8的药包片材的特征是在技术方案5、技术方案6或技术方案7中，三角形状的切口的对置的斜边所成的角度为110度以下，所以在药剂包装机内的药剂的包装过程中，即使在塑料片材被拉伸的情况下，塑料片材也难于裂开，而且在撕开分包袋时，三角形状的切口角度够大，例如，不会使患者撕开分包袋的力难于集中。由此，能够适用于在药剂包装机内的药剂的包装，而且能够提供使患者能够容易地撕开的三角形状的切口。
技术方案9的药包片材的特征是在技术方案5、技术方案6、技术方案7或技术方案8中，三角形状的切口底部为半径2μm～10μm的弯曲形状，所以在形成切口时不会使从其底部露出切缝。由此，能够防患于未然地防止分包袋向与所想相反的方向裂开并使药剂从分包袋内撒出的问题。
技术方案10的药剂包装机使用技术方案5、技术方案6、技术方案7、技术方案8或技术方案9的任一项的带状的药包片材，通过制造在内部收纳有药剂的状态下是连续的、在服用时分离的多个分包袋来包装前述药剂，所以能够在塑料片材的阶段预先在两侧端缘部形成切口。由此，能够容易地在连续的整个分包袋上形成切口。所以，能够大幅降低收纳药剂的分包袋的成本。
此外，技术方案11的分包袋对技术方案5、技术方案6、技术方案7、技术方案8或技术方案9的任一项的带状的药包片材的侧端缘部进行对合热熔敷的同时，在与前述药包片材的长度方向垂直的方向上热熔敷规定的宽度而得，以在内部收纳有药剂的状态下是连续的、在服用时能够分离的方式构成，且形成有前述切口的部分不进行热熔敷，所以能够防止从三角形状的切口部分泄漏已溶解的药包片材的原材料。由此，能够防患于未然地防止泄漏的药包片材原材料附着在药剂包装机上、或分包袋的美观恶化等的问题。
技术方案12的分包袋的特征是在技术方案11中，对合热熔敷部位与切口的底部间隔0.5mm～1.0mm，所以能够有效地防止溶解的药包片材的原材料在三角形状的切口一端泄漏。由此，能够防止药包片材的侧端缘部粘贴在药剂包装机上的问题。所以，能够防患于未然地阻止药剂包装机的动作性能降低。
技术方案13的药剂包装机通过制造技术方案11或技术方案12所述的分包袋来包装前述药剂，所以能够大幅提高药剂包装机的性能。所以，能够极大地提高药剂包装机的便利性。

具体实施方式
以下，基于附图详细说明本发明的实施方式。图1(A)是模式地表示成为本发明所使用的一实施例的药包片材20的部分俯视图。图1(B)是模式地表示将图1(A)的药包片材20的对折后的状态的部分俯视图。此外，在实施例中虽然基于具体化的实施例来说明本发明，但这些不过表示了其代表例，还能够实施各种设计变更。
药包片材20的原材料是由在厚度10μm～100μm、优选为10μm～50μm、更优选为12μm～40μm的聚对苯二甲酸乙二醇酯(PET)片材40(图3)的内表面上粘接并层叠厚度10μm～50μm、优选为15μm～40μm的低密度聚乙烯片材41而得到的带状透明复合塑料片材42构成。①在该药包片材20的两侧端缘部43、43设有被切削加工成间距宽度0.5mm～10mm、优选为0.5mm～4mm左右的波状(图1)的切口44。此外，药包片材20的两侧端缘部43、43被切削加工成间距宽度0.5mm～10mm、优选为0.5mm～4mm左右的三角形状(交错的锯齿状)的切口44也可以(图2)。
此外，药包片材20的两侧端缘部43、43在②PET片材40上用具有无数微细金刚石粒的辊进行推压，由此在整个表面形成无数的微细疵点(未图示)也没关系。进而，在③PET片材40的整个表面上形成无数的微细疵点(未图示)，而且在其两侧端缘部43、43设置前述任一种形状的切口44都可以。前述PET片材40能够替换成2轴延伸聚丙稀片材。
此外，以在印刷图案或文字等的PET片材40的印刷面40A上，粘接并层叠低密度聚乙烯片材41的方式构成(图3)时，图案或文字等不易消失，能够长时间地维持清晰，是比较理想的。
此外，能够以在硅蒸镀或铝蒸镀的PET片材40的蒸镀面上粘接层叠低密度聚乙烯片材41的方式构成。进而，也可在透明复合塑料片材42的PET片材40一侧的长度方向的一半上形成通过镀膜形成的能够打印的白色的显示面。
进而，也可使用由取代低密度聚乙烯片材41而粘接层叠聚丙稀片材等代表的其它能够与食品接触的塑料片材而得到的透明复合塑料片材42。
能够使用具有形成为例如三角形状(交错的锯齿状)的刀刃的辊子来将很宽的该塑料片材一边连续地切成所希望的规定宽度一边卷取，由此简单地制造前述①～③的透明复合塑料片材42。
这样构成的药包片材20在低密度聚乙烯片材41的一个面上重合并接合有PET片材40，所以在其中央部，以低密度聚乙烯片材41一侧为内表面侧的方式对折时，能够使两端完全重合，接着通过对3方进行对合热熔敷而能够一连串地划分形成。即，在后述的热熔敷型的自动药剂包装机1中，能够作为对配好的药剂连续分包的分包袋36的药包片材20使用。
在这里，用图5来进行对在上述药包片材20内投入作为药剂的固态制剂并包装的药剂包装机1的说明。药剂包装机1设置在医院或配药药店等，由设在矩形的外装箱2内的药剂收纳机构3及设于其下方的药剂包装机构14等构成。在外装箱2内的上部形成有药剂收纳机构3的片剂盒收纳部5，该片剂盒收纳部5通过顶盖4而开闭自如地闭塞上面开口。
片剂盒收纳部5的内部收纳有多个片剂盒6，在其前上部设有副收纳部7。该副收纳部7收纳不能收纳在前述片剂盒6内的药剂(例如，切成一半的药片等)，通过马达8的未图示的旋转轴的滑轮所张紧的皮带9而驱动未图示的传送带(在这种情况下，也可由链或齿轮等连接)。在传送带上连续设有多个收纳分部7A。
此外，在各片剂盒6的下部分别设有未图示的光敏传感器等的排出计数装置。该排出计数装置与上侧的各片剂盒6分别连通的同时，在内部内装有马达驱动式的排出鼓轮。此外，排出鼓轮的构造为：在形成于侧面的多个槽内上下一列地放入前述药片、胶囊剂、丸剂、片剂等的固态化制剂的药剂。其构成为：通过排出鼓轮的旋转，药剂从各槽内一个个落下，其数量通过前述光敏传感器来进行检测并计数。
此外，在副收纳部7的一端形成下落通路，该下落通路与后述的转台10上连通。在相关的副收纳部7的收纳分部7A内分别收纳如前所述的药剂，通过使用者的开关操作来旋转马达8，由此以各收纳分部7A的药剂从下落通路一个个地落到转台10上的方式构成。
在各片剂盒6及前述下落通路的下方设有用于收集药剂的圆盘状的转台10，该转台10具有与前述全体片剂盒6及下落通路的下方对应的面积。此外，在转台10的中心部形成鼓起成圆锥状的***部10A，通过设于该***部10A下方的未图示的转台马达，以规定的速度来旋转驱动转台10。
此外，在转台10的周围立起设置有环状的导向部11，在导向部11的适当部位切口形成有排出口D。在相关排出口D的下方设有后述的滑槽13，通过该转台10的旋转而收集在导向部11一侧的药剂落在该滑槽13内。该滑槽13呈逆四边锥形，其上端开口与前述转台10的排出口D对应，同时，开口的下端(前端)与对折的药包片材20间的上方对应。
另一方面，药剂包装机构14设在该转台10的下方，该药剂包装机构14由安装后述的药包片材滚筒19的安装机构、将被拉出的药包片材20导引到规定的位置的导引机构、及拉住药包片材20的前端的牵引机构配置在底座15上而构成(图5)。如图6所示，药包片材安装机构由旋转自如地立起设置在底座15上的旋转轴16、位于该旋转轴16的底部并向外侧突出的圆盘状的载置板17、配设在该载置板17的下侧(与底座15之间)的螺线管驱动的制动器18等构成。
该旋转轴16呈具有与后述的药包片材滚筒19的轴件21的内径大致相同(比其稍小)的外径的圆柱状，该旋转轴16能够装卸地***形成于药包片材滚筒19上的轴件21内，在这里，药包片材滚筒19由硬质合成树脂制(也可为厚壁纸制)的中空管状轴件(通常称为纸管)21、及卷绕在其周围的前述药包片材20构成(图7、图8)。该药包片材20以在前述轴件21的周围将规定宽度的纵长的带状物卷绕成滚筒状的方式设置。
药包片材20在靠近如前所述的宽度方向的大致中心部的位置对折而折弯成两折，使该被折弯成两折的折弯部为折痕部20A、被折弯成两折的两端部(与折痕部20A相反的一侧)为开口部20B。在该药包片材20被折弯成两折的状态下，折痕部20A作为轴件21的下端缘侧而被卷绕到该轴件21上，从卷绕的药包片材20的最终端拉出(图9)。
在前述药剂包装机构14上设有位于旋转轴16的侧方并作为导引机构的张力杆23，张力杆23架设在2根辊24、25之间。此时，辊24固定在底座15上，辊25以该辊24为中心可自由摆动。该辊25通过未图示的弹簧件向离开旋转轴16的方向施力。此外，通过未图示的开关来检测该辊25的位置。此外，26是导引辊，立设在辊24的侧方的底座15上。
在隔着旋转轴16与张力杆23相反一侧的底座15上设有作为牵引机构的牵引辊30。该牵引辊30由一对宽度较窄的橡胶辊(天然橡胶或合成橡胶等的辊)33、33A构成、且旋转自如地安装在旋转轴32、34的上端。此外，安装有一个橡胶辊33的旋转轴32是牵引马达31的旋转轴。
此外，另一个橡胶辊33A的旋转轴34通过来图示的螺旋弹簧等施力，以规定的压力将一个橡胶辊33A压接在橡胶辊33上，以通过牵引马达31的旋转而使两橡胶辊33、33A旋转的方式构成。通过在该两橡胶辊33、33A之间夹持药包片材20(开口部20B侧)，由此用药包片材滚筒19拉出药包片材20。
此外，在导引辊26与牵引辊30之间设有热封机构27(图10)。该热封机构27通过对合热熔敷来密封前述药包片材20的开口部20B，而且按每次配药量区分开，由以规定的间隔对置设置的一对临时加热器28、28及一对的主加热器29、29构成。此外，任一方的临时加热器28及主加热器29设有未图示的动作装置，在对置的任一方的临时加热器28及主加热器29上压接或离开自如地构成。通过对各临时加热器28及主加热器29通电，将其加热到规定的温度。
此外，主加热器29、29分别由垂直部29A、29A与平行部29B、29B构成，平行部29B具有与临时加热器28大致相等的宽度，并且垂直部29A具有平行部29B的2倍的宽度。用临时加热器28夹持药包片材20的两侧并加热，由此在药包片材20的折痕部20A一侧到开口部20B的大致中间部进行热熔敷(图10实线箭头范围不热熔敷固定)
此外，主加热器29的垂直部29A进一步从两侧夹持用临时加热器28加热并热熔敷的部分并对从药包片材20的折痕部20A一侧到开口部20B的部分进行热熔敷固定，以在一方设有开口部20B的小袋36A形成在临时加热器28一侧的方式构成。此外，平行部29B构成为：对处在临时加热器28相反一侧的开口部20B进行热熔敷(在该情况下，为从主加热器29到临时加热器28间的尺寸)。
由相关热封机构27对药包片材20进行热熔敷之后，通过牵引辊30的旋转在牵引辊30一侧(图10中空心箭头方向)上移动规定距离，即，由临时加热器28热熔敷的部分移动到主加热器29(到达从折痕部20A到开口部20B的主加热器29的热熔敷部分)。通过使用主加热器29来热熔敷药包片材20，能够依次在临时加热器28与主加热器29的垂直部29A之间形成设有开口部20B的小袋36A的同时，以在牵引辊30一侧形成其折痕部20A以外的部分被热熔敷的分包袋36的方式构成。
此外，在主加热器29对从临时加热器28以上的药包片材20的折痕部20A到开口部20B的部分热熔敷时，在热熔敷部的宽度的大致中心(从折痕部20A到开口部20B)形成设有多个针眼37(针眼状的孔)的断缝。由此，药包片材20的三方(剩余的一方是折痕部20A)被热熔敷，形成其全周都封闭的分包袋36的同时，以从针眼37切离而能够分离分包袋37的方式构成。
通过以上的构成，接着说明本发明的药剂包装机1的操作顺序及动作。首先，一边在药包片材滚筒19的轴件21内***旋转轴16一边将药包片材滚筒19载置于载置板17上。此时，在折痕部20A位于载置板17一侧的状态下***旋转轴16。如前所述，该药包片材滚筒19由将药包片材20对折并卷绕在轴件21上而成，因为具有折痕部20A与开口部20B，所以在相反地安装药包片材滚筒19的上下部分时，折痕部20A与开口部20B逆转，不能进行在药剂包装机构14内的药剂的包装。
这样将药包片材滚筒19安装在旋转轴16之后，从前端拉出该药包片材滚筒19的药包片材20，依次经过张力杆23的辊25、24的外侧并通过导引辊26的内侧，接着经过临时加热器28、主加热器29之间(滑槽13被放倒)，绕到牵引辊30上(图9)。
将药包片材20的前端***牵引辊30的两橡胶辊33、33A之间，驱动牵引马达31时，橡胶辊33、33A一边相互压接一边将药包片材20向热封机构27的相反侧(眼前侧)方向拉伸，药包片材20通过牵引辊30而被牵引，被拉出到眼前侧。
在这里，张力杆23的辊25在药包片材20的张力增强时向旋转轴16方向移动，在张力变弱时向离开旋转轴16的方向移动。通过如前所述的开关来检测该辊25的移动，在从旋转轴16离开的情况下通过未图示的控制装置来驱动螺线管，制动器18被压在载置板17上。在辊25向旋转轴16方向移动时，这次使制动器18离开。由此，能够以对从药包片材滚筒19拉出的药包片材20施加一直适度的张力的方式构成。
这样将药包片材滚筒19安装到旋转轴16上，开动已经拉出并装填了药包片材20的药剂包装机1时，对数出药剂的下落数量的计数值清零。此外，临时加热器28及主加热器29被加热到规定的温度，转台10通电并一直旋转。作业者基于医生的处方条，将处方数据输入未图示的输入装置(微型计算机等)时，收纳该药剂的片剂盒6的排出鼓轮被旋转驱动，通过该处方数据而指定的种类的药剂一个个地落到转台10上。此外，来自副收纳部7的药剂也通过使用者的任意操作而同样地落到转台10上。
从片剂盒6落下的药剂的数量基于光敏光传感的输出而通过未图示的控制装置计数，在计数的药剂的落下数量与基于前述处方数据的药剂的数量一致后，停止排出鼓轮的旋转，结束药剂的下落。落到该转台10上的药剂(含有来自副收纳部7的药剂)由于旋转的转台10的离心力而向外侧的导向部11的方向移动并收集，落到设于导向部11上的排出口D下方的滑槽13内。由此，药剂穿过滑槽13内并投入到位于其下方的药包片材20的小袋36A中。
这样将药剂收纳在药包片材20的小袋36A中之后，控制装置通过牵引辊30来拉伸药包片材20，由热封机构27进行如前所述的对合热熔敷，由此进行密封。
在这里，在滑槽13的下端安装有进入小袋36A内并扩开开口部20B的未图示的挡板，此时，热封机构27的临时加热器28对从药包片材20的折痕部20A侧到开口部20B的大致中间部的部分进行热熔敷，因为其上方不热熔敷，所以不必使滑槽13的挡板上升，能够用牵引辊30来牵引药包片材20(图9箭头方向)。
停止药包片材20的移动时，通过主加热器29再次进行药包片材20的热熔敷，药剂被包装到分包袋36中的同时，通过转台10经由滑槽13而收纳在小袋36A中。通过反复进行该操作，能够自动地将基于处方数据的种类的药剂包装成规定数量。此外，在图10中，虽然表示了用临时加热器28及主加热器29对后述的纵向熔敷部38、横向熔敷部39进行热熔敷，但实际上对离开针眼37部分规定尺寸的两侧位置进行热熔敷的同时，主加热器29的平行部29B对形成在分包袋36的开口部20B一侧的横向熔敷部39(含有波状或锯齿状部分)进行热熔敷。
在这里，药包片材20的热熔敷部如图11所示，将分包袋36区分成大致相等的间隔，由在与带状的药包片材20的长度方向垂直的方向上密封的纵向熔敷部38及连结该纵向熔敷部38、且在与长度方向相同的方向上密封带状的药包片材20的对合面的横向熔敷部39构成。即，如前所述药包片材20从折痕部20A对折并通过药剂包装机1对纵向熔敷部38与横向熔敷部39进行对合热熔敷的同时，在纵向熔敷部38上通过打眼刀具形成针眼37。由此，能够简单的将各分包袋36切离。
此外，在使用形成有波状或锯齿状的切口44的药包片材20的情况下，在从药包片材20的折痕部20A对折时，以波状或锯齿状的两侧端缘部43、43相互完全重合的方式来构成切口44。此外，药包片材20的两侧端缘部43、43形成为间距宽度0.5mm～2mm左右的短波状或锯齿状时，即使在药包片材20的折痕部20A对折时不完全重合，也能够对横向熔敷部39进行热熔敷(参照图1(B))。由此，能够在分包袋36的开口部20B一侧形成切口44，所以是比较理想的。
在前述②PET片材40一侧，形成无数微细的疵点(未图示)，在前述③PET片材40的整个表面形成无数微细的疵点，而且使用其两侧端缘部43、43形成切削加工成波状或锯齿状的切口44的药包片材20，与前述同样地能够用热熔敷型的自动药剂包装机1来连续分包已经配好的药剂。
在使用这些药包片材20时，因为在PET片材40的整个表面形成无数微细的疵点，在从横向熔敷部39的任意位置向与横向熔敷部39垂直的方向拉伸时，能够简单的将收纳药剂的分包袋36撕开。
此外，根据本发明的分包袋36，能够不沿热熔敷部而沿未热熔敷部(折痕部20A)导引分包后的药剂，所以即使是粉剂等的微细颗粒也不会残留而能够可靠地服用。
这样收纳药剂的分包袋36虽然由药包片材20对折并用药剂包装机1对横向熔敷部39进行对合热熔敷所得，但在用药剂包装机1对横向熔敷部39(含有波状或齿状形状部分)进行对合热熔敷的情况下，有时溶解的药包片材原材料在药包片材20的三角形状的切口44一端上泄漏并附着在主加热器29的平行部29B上。在三角形状的切口44一端漏出的原材料附着在平行部29B上时，药包片材20的侧端缘部43粘贴在平行部29B上且用牵引辊30不能牵引药包片材20，在药剂包装机1上产生故障。
所以，在图12表示能够防止溶解的药包片材原材料在三角形状的切口44一端泄漏的分包袋36。在这种情况下，药包片材20的结构是制造在内部收纳有药剂的状态下是连续的、在服用时分离的多个分包袋36的与前述同样的带状。该药包片材20的原材料与前述材料由同样的透明复合塑料片材42构成。在该药包片材20(透明复合塑料片材42)的两侧端缘部43、43形成与前述相同的交错的锯齿状大致相同的三角形状的切口44、44。
切口44形成为由斜边的前端位于折痕部20A方向的底部44A及斜边的前端位于离开折痕部20A的方向的山部44B构成的三角形状。在药包片材20通过折痕部20A对折的状态下，以设在药包片材20一侧的三角形状的切口部44底部44A与设在另一侧的三角形状的切口44底部44A重合的方式构成(图13的双点划线)。在这种情况下，不用说就能知道设在药包片材20一侧的三角形状的切口部44山部44B与设在另一侧的三角形状的切口44山部44B重合。即，药包片材20的两侧端缘部43、43在药包片材20从折痕部20A对折时，以两侧的三角形状(两切口44、44)相互重合并大致吻合的方式构成(图14)。
此外，切口44的底部44A的角度α、即三角形状的切口44的对置的斜边所成的角度α形成为110度以下(在这种情况下为110度～100度之间)的同时，设在侧端缘部43的横向熔敷部39与切口44底部44A稍稍接触并对两横向熔敷部39进行对合热熔敷(图15)。其它与前述同样地构成。此外，纵向熔敷部38的热熔敷不在针眼37的中央部分进行，以规定宽度(在这种情况下，大致为纵向熔敷部38的宽度尺寸)对针眼37的两端部进行热熔敷的同时，对邻接的分包袋36的纵向熔敷部38连续热熔敷(图12)。
由此，在取出收纳于分包袋36内的药剂时，因为能够沿药包片材20(透明复合塑料片材42)的切口44而撕开分包袋36，即使是例如与以往使用的聚乙烯层压赛璐芬纸、或聚乙烯层压玻璃纸等的包装纸相比而难于撕开的透明复合塑料片材42构成的分包袋36，也能够从所希望的位置的切口44部分简单地撕开。
在这种情况下，因为形成切口44的部分未热熔敷，所以能够防止溶解的药包片材原材料在三角形状的切口44一端泄漏。由此，能够消除三角形状的切口44底部44A的漏出的原材料所致的包装机构的故障，且能够不损害分包袋的撕开容易程度或美观。
此外，在药包片材20从折痕部20A对折时，因为两侧端缘部43、43的切口44相互大致吻合，所以作用在设于分包袋36的两侧端缘部43、43的切口44部分(三角形状的底部44A)的切入力易于集中。此外，在作用于分包袋36的两侧端缘部43、43的切口44部分的切入力集中时，能够以比较小的力从切口44部分撕开分包袋36。由此，即使是老人或小孩、特别是手的力气较小的病人，也能够从药包片材20(透明复合塑料片材42)对折所得的分包袋36的两侧端缘部43、43的切口44简单地撕开。
此外，因为三角形状的切口44的对置的斜边所成的角度α形成为110度以下，在药剂包装机1内的药剂的包装过程中，即使在药包片材20(透明复合塑料片材42)被拉伸的情况下，透明复合塑料片材42也难于裂开，而且在撕开分包袋36时，切口44的角度α够大，例如，不会使患者撕开分包袋36的力难于集中。由此，能够适用于在药剂包装机1内的药剂的包装，而且能够提供患者能够容易地撕开的分包袋36。
接着，在图16表示本发明的其它的实施例的分包袋36。在这种情况下，使分包袋36的切口44与横向熔敷部39隔开规定的间隙，对横向熔敷部39进行对合热熔敷。即、使热熔敷部位(横向熔敷部39)离开切口44底部44A0.5mm～1.0mm(图17箭头范围)。由此，在对横向熔敷部39进行了对合热熔敷的情况下，因为漏出的密封剂收纳在横向熔敷部39与切口44之间并不流到切口44一端，所以能够更有效地防止溶解的药包片材原材料在三角形状的切口44一端泄漏，并且能够消除三角形状的切口44底部44A泄漏的原材料所致的对撕开容易程度的损害。
特别是，因为使分包袋36的切口44与横向熔敷部39隔开规定的尺寸，所以患者在撕开分包袋36时，能够使其撕开力集中在分包袋36的三角形状的切口44底部44A，即使是老人或小孩、特别是手的力气较小的病人等，也能够简单地撕开分包袋36。
接着，图18表示本发明的其它分包袋36。在这种情况下，药包片材20的两侧端缘部43、43的切口44也形成为由斜边的前端位于折痕部20A方向的底部44A及斜边的前端位于离开折痕部20A方向的山部44B构成的三角形状。在药包片材20通过折痕部20A对折的状态下，以设在药包片材20一侧的三角形状的切口部44底部44A与设在另一侧的三角形状的切口44山部44B重合的方式构成(图18的双点划线)。在这种情况下，不用说就能知道设在药包片材20一侧的三角形状的切口部44山部44B与设在另一侧的三角形状的切口44底部44A重合。即，药包片材20的两侧端缘部43、43在药包片材20从折痕部20A对折时，以两侧的三角形状(两切口44底部44A与山部44B)相互错开的方式构成(图19)。
由此，在从设于药包片材20的两侧端缘部43、43的切口44部分撕开分包袋36时，能够错开分包袋36被撕开的端部。此外，能够撕开分包袋36并从错开的端部容易地打开该分包袋36。所以，使用者能够极其简单地取出分包袋36内的药剂。
接着，图20表示本发明的其它的分包袋36。在这种情况下，使药包片材20的两侧端缘部43、43的三角形状的切口44底部44A及山部44B形成为弯曲形状。详细的说，使药包片材20的两侧端缘部43、43的三角形状的切口44底部44A的半径R为2μm～10μm的弯曲形状(图21箭头)。在这种情况下，三角形状的切口44底部44A的弯曲形状的大小为：在药剂包装机1内的药剂的包装过程中，即使在药包片材20被拉伸的情况下，药包片材20也难于裂开，而且在从切口44部分撕开分包袋36时，患者能够容易地撕开分包袋36的弯曲形状。此外，使对合热熔敷部位(横向熔敷部39)与切口44底部44A间隔规定尺寸(在这种情况下与前述同样地间隔0.5mm～1.0mm)。
在这里，在药包片材20的两侧端缘部43、43上设有通过未图示的刀具而连续地切削斜边所得的三角形状的切口44时，若不将斜边的前端切入底部44A的稍前方(山部的相反侧方向)，则不能够切成三角形状。即，在对切口44底部44A上未形成弯曲形状的三角形状的切口44进行连续加工的情况下，在三角形状的底部44A上怎么切都会形成从底部44A上突出并延长的延长切削部44C(图22)。
在三角形状的底部44A上形成延长切削部44C时，在撕开分包袋36时，会产生分包袋36向与所想相反的方向裂开并使药剂从分包袋36内撒出的问题。所以，在图20、图21的实施例中，在药包片材20的两侧端缘部43、43的三角形状的切口44底部44A上设计弯曲形状，能够防止分包袋36向与所想相反的方向裂开并使药剂从分包袋36内撒出的问题。
此外，若以上述的尺寸使药包片材20的切口44底部44A为规定的弯曲形状，则在药剂包装机1内的药剂的包装过程中，药包片材20难于裂开，患者在撕开分包袋36时，能够使其撕开力集中在分包袋36的三角形状的切口44底部44A上。由此，因为分包袋36易于沿着切口44的方向撕开，所以能够防止分包袋36向与所想相反的方向裂开并使药剂从分包袋36内撒出的问题。此外，虽然在图中三角形状的切口44山部44B也为弯曲形状，但切口44山部44B的形状仍为三角形状也可。
此外，在图23表示其它的例子的分包袋36。在这种情况下，取代在分包袋36上设置三角形状的切口44而在端部设置多个断缝45。从分包袋36的开口部20B朝向折痕部20A方向设计约0.5mm～1.0mm的断缝45。此外，断缝45即使是更小的尺寸，若能够从断缝45部分撕开分包袋36，就不局限于上述尺寸。这样因为取代三角形状的切口44而在分包袋36上设置多个断缝45，所以即使是老人或小孩、特别是手的力气较小的病人，也能够简单地撕开分包袋36。
此外，虽然在实施例中将固态制剂作为药剂进行了说明，但药剂不局限于相关固态制剂，本发明也适用于颗粒制剂或粉末制剂。
