Description

储存袋
技术领域
本公开涉及储存袋，更具体地，涉及冷冻保存袋。
背景技术
一次性柔性容器用于运输或储存材料诸如生物制品。这种容器是柔性的袋，通常由塑料膜制成。所述袋可用于储存，特别是在冷冻保存应用中。所述袋通常是一次性的，并旨在降低交叉污染的风险和卫生标准的需要。
在冷冻保存应用中，生物原料药物质在储存袋中储存和运输冷冻。这保持蛋白质在储存期间的稳定性。现有的袋具有某些缺点，包括在冷冻温度(可以低至-80℃)下以及袋的预热和使用期间的耐久性。现有储存袋中还存在塑料可提取物与药物物质相互作用的风险。此外，现有的袋趋于具有泄漏问题，特别是在袋的端部和转角处。
因此，期望具有改进的耐久性、低可提取物、减少泄漏的特别用于低温应用的储存袋。

所述较低熔点聚合物是可熔融加工的聚合物；所述较低熔点聚合物是氟化乙烯丙烯(“FEP”)。
在特别优选的实施方案中，本公开提供了制备冷冻保存袋的方法，所述方法包括以任何顺序进行的以下步骤：(a)形成复合物管，所述复合物管具有包括不可熔融加工的聚合物的内表面，包含可熔融加工的聚合物的外表面、两个端部以及将所述管分成第一半和第二半的直径；(b)在所述管的两个端部中的至少一端提供所述管的第一半的延伸部；(c)在垂直于所述直径的方向上压平所述管；(e)将所述延伸部划分成具有边缘的至少三个区段；(f)折叠所述三个区段，使得所述边缘与所述管的第二半结合以形成接合部；(g)提供复合片，所述复合片具有包含不可熔融加工的聚合物的第一侧和包含可熔融加工的聚合物的第二侧；和(h)在接合部上折叠所述复合片，使得包含可熔融加工的聚合物的第二侧与接合部接合以在接合部上形成搭接缝。

发明详述
本领域的技术人员应理解，可通过用于发挥所需作用的任何数量的方法和设备来实现本公开内容的各个方面。还应注意，本文参考的附图不一定是按比例绘制，而是有可能放大以说明本公开的各个方面，就此而言，附图不应视为限制性的。
现在将结合附图描述本公开的优选实施方式。在图1中，示出了示例性储存袋10。储存袋10由具有端部14a和14b以及前侧70和后侧71的复合物管11形成。本实施方式中的端部14a是手柄端。本实施方式中的端部14b是端口端。端口端14b具有夹具3和在其上形成的端口2。端口2可以通过穿刺端口端14b形成。具体地，在形成复合物管11之前，在其中刺破孔，然后将具有端口2的模制件附接到复合物管11的外部。然后如本文所述进行用于形成袋的后续步骤。在优选实施方式中，在复合物管11形成后，提供具有端口2的模制件并将其附接到袋上。本实施方式中的手柄14a具有形成在其中的手柄4。
在每个端部14a和14b处，折叠复合物管11以形成接合部15。同样在每一个端部14a和14b处,离散的复合片20设置在接合部15上以在接合部15上形成搭接缝。如本文所使用的，“接合部”是指包括两个邻接边缘、接近邻接的边缘和重叠的边缘的界面；“搭接缝”是指具有彼此重叠的边缘的接缝；并且“冷冻保存”意指在低于零摄氏度的冷温度下的储存或保存。
复合物管11优选通过形成如图2所示的复合材料片的管而形成。复合物管11具有内表面12，所述内表面12优选地包括较高熔点聚合物。复合物管11还具有外表面13，所述外表面13优选地由低熔点聚合物形成。本文所用的“较高熔点聚合物”是指熔点比“较低熔点聚合物”至少高30℃，优选高50℃的聚合物，并且“较低熔点聚合物”相应地是指聚合物的熔点低于较高熔点聚合物至少50℃。优选地，所述较高熔点聚合物是不可熔融加工的聚合物，例如聚四氟乙烯或聚酰亚胺(如
Figure BDA0002682792790000041
)，所述较低熔点聚合物是可熔融加工的，例如氟化乙烯丙烯(“FEP”)。复合物管11具有直径D，将复合物管11分成第一半和第二半。复合物管11沿垂直于直径D的方向压平，以形成储存袋10。使用本公开的优选实施方式，通过用搭接缝覆盖接合部，提供了在存储袋的端部和转角处增强的泄漏保护的显著优点。图3中示出了本公开的特别优选实施方式。图3是复合物11的端部14a的视图。复合物管11的端部14a具有延伸部18。延伸部18是复合物管11的一半的延伸。在所示的该优选实施方式中，延伸部18分成19a、19b和19c三个区段。所述区段19a、19b,和19c分别地具有如图所示的边缘30a,30b和30c。三个区段19a，19b和19c中的每一个沿折叠线K折叠，如图3和图4所示，使得边缘30a，30b和30c与复合物管11的另一半接合以形成第一接合部15。
参考图4，单独的复合片20具有由较高熔点聚合物形成的第一侧(未示出)和由较低熔点聚合物形成的第二侧21b。复合片20设置在接合部15上，在接合部15上在复合片20与复合物管11之间形成搭接缝。在特别优选的实施方式中，折叠复合片20，使得在复合物管11的相对侧也形成搭接缝。图4还示出复合物管11被压平后的边缘40a和40b。
在替代实施方式中，可以使用两个单独的复合片20，所述复合片在复合物管11的每一侧上各一个，而不是在一个复合片20上折叠。在任何实施方式中，复合片20的较低熔点的表面与复合物管11的较低熔点的表面结合，以在接合部15上产生搭接缝。
图5-9示出了替代实施方式。图5示出了复合物管的一半的延伸部58，以及在复合物管的另一半的转角处的部分延伸部59，所有这些部分在折叠线B上折叠，如图6所示。图7示出复合物管的一半的延伸部78，其在折叠线C上折叠并且覆盖有离散的复合片20，如图8所示。图9示出其上具有突出部99的特定形状的延伸部98。突出部99沿折叠线X折叠，延伸部98围绕折叠线E折叠，并且所述延伸部覆盖有离散的复合片20，如图10和11所示。图12示出复合物管的一半的延伸部128以及复合物管另一半的延伸部128a，它们一起限定转角129。转角129沿折叠线F折叠，然后如图14所示将延伸部沿折叠线G折叠。图15示出复合物管的一半的延伸部158，使所述延伸部158成形为限定复合物管的另一半的转角159。转角159围绕折线H折叠，并且延伸部沿折叠线J折叠并且用离散的复合片20覆盖，如图16所示。
虽然在此未具体示出，但是储存袋10的端口端14b在接合部上以类似于上述结合手柄端14a的方式设置有搭接缝。这样，优选地在端口端14b上的延伸部18中形成狭缝，以便于端口2的附接。手柄4和夹具3可以如本领域中已知的那样形成。
上文已经中概括性地并且结合具体实施方式描述本申请的发明。对本领域的技术人员来说显而易见的是，可以在不偏离本发明的精神和范围的情况下，对本文所述的实施方式进行各种修改和变动。因此，实施方式旨在覆盖对本发明的这些修改和变动，只要这些修改和变动在所附权利要求及其等同方案的范围之内即可。
