For example, a composite sheet including an inner layer and an outer layer formed by selecting different materials from plastic materials such as polyethylene terephthalate, nylon, polypropylene, and polyethylene can be used. A thin film such as aluminum oxide or silica may be formed on the composite sheet as a barrier layer. It is preferable that at least one of the two sheets is transparent or translucent so that the amount of the liquid material in the container body 10 can be confirmed. When two sheets are sealed by a general heat sealing method in a medical container, a heat seal layer is provided on the surface of each sheet facing the counterpart sheet.
The port 50 is made of a material that is relatively hard compared to the container body 10 such as polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, ethylene vinyl acetate copolymer, thermoplastic elastomer, polyacetal, and the like. Can be manufactured.

  Next, an example of the usage method of the container 1 of this embodiment is demonstrated. The container 1 is supplied to a hospital or the like in an empty state. In a working room such as a hospital, the prepared liquid material is poured into the container 1. The liquid material is injected through the port 50. Furthermore, the medical container of the present invention will be described in detail while showing a preferred embodiment.

  FIG. 2 is a perspective view showing a schematic configuration of the medical container mount 100 according to the embodiment of the present invention. For convenience of the following description, as shown in the drawing, an XYZ orthogonal coordinate system is set in which the X axis is the width direction axis, the Y axis is the depth direction axis, and the Z axis is the vertical axis. The direction of the illustrated arrow is the positive direction of the X axis, the Y axis, and the Z axis. That is, the right side of the X axis is the positive side, the left side is the negative side, the Y axis is the positive side, the rear side is the negative side, the Z axis is the positive side, and the lower side is the negative side.

  Three side plates 110L, 110C, 110R parallel to a plane including the Y axis and the Z axis (hereinafter referred to as “YZ plane”) are arranged at substantially equal intervals in the X axis direction. A medical container suspension base 130 extending in the X-axis direction is spanned and supported by the upper ends of the three side plates 110L, 110C, 110R. A pair of support bars 121L, 122L connect the lower ends of the side plates 110L, 110C adjacent to each other, and a pair of support bars 121R, 122R connect the lower ends of the side plates 110C, 110R adjacent to each other.
