    • PROBLEM TO BE SOLVED: To provide a valve structure in which a valve sheet is not fused to an outer sheet on heat-sealing to a sealed bag.SOLUTION: The right and left sides of three valve constituting sheets 1 and 1 are side-sealed, and opposed valve constituting sheets 1 and 1 are brought into close contact with each other to restrict a fluid from moving. The inside and the outside of a bag body are partitioned by a partition seal, the valve is disposed across the inside and the outside of the bag body, and welded to the bag body by the partition seal. One of the opposed surfaces of the valve constituting sheets is formed of a non-weldable film that is not welded by welding of the side seals and the partition seal. The side seals become non-welded parts to be non-welded in the part of the non-weldable film on the downstream side in the mocing direction of the fluid from the partition seal and side-entering preventive sealed parts that block flows of the fluid into the movement channel from the non-weldable parts are provided continuously to the partition seal on the outer side in the right and left directions of the non-weldable parts.
    • 要解决的问题:提供一种阀门结构,其中阀片不与外部片材熔合而密封在密封袋上。 解决方案:三个阀构成片材1和1的右侧和左侧被侧密封,并且相对的阀构成片材1和1彼此紧密接触以限制流体的移动。 袋体的内部和外部由分隔密封件隔开,阀被设置在袋体的内部和外部,并通过分隔密封件焊接到袋体上。 阀构成片材的相对表面之一由不能焊接侧密封件和分隔密封件的不可焊接膜形成。 侧密封件成为非焊接部件,在来自分隔密封件的流体的流动方向的下游侧的不可焊接膜的部分中被非焊接,并且阻止流体流动的侧面进入的预防性密封部件 在不可焊接部分的左右方向的外侧连续地设置有从不可焊接部分移动的运动通道。 版权所有(C)2012,JPO&INPIT
