- the bridge connects the communication member and the cap main body so as to straddle the flow path that allows the liquid material filled in the container main body to flow out of the nutrient container.
- the bridge since the bridge is disposed so as to cross the lumen (flow path) in the communication member, it is difficult to insert a connection needle having a sharp tip into the communication member, and the above-described erroneous connection can be prevented more reliably.
- the connecting member can be pushed into the container body part side by bending and deforming the part including the bridge from the connecting part between the cap body part and the bridge to the connecting part between the bridge and the communication member. And in this case, since the thin film can be broken while the cap main body portion and the communication member are connected, it is preferable that the communication member can be reliably prevented from falling into the container main body portion and floating in the liquid material.
- the portion including the bridge from the connection portion between the cap main body portion and the bridge to the connection portion between the bridge and the communication member includes three thin portions and each of the three thin portions is bent and deformed, the communication member is It can be easily pushed into the container body. If the number of thin portions is three, when the communicating member is pushed into the container body, the bridge may break due to the small number of thin portions, or the bending may occur due to the excessive number of thin portions. Complexity is suppressed and preferable.
- the cap is provided with a protective cover that covers the communication member and includes an engaging portion that can be engaged with the connection holding structure of the cap.
- a protective cover that covers the communication member and includes an engaging portion that can be engaged with the connection holding structure of the cap.

- the bridge may include one or more thin sections, although it is allowed to push into the bridge. If a force to push the communication member 49 toward the thin film side is applied to the communication member 49 by bending, the movement of the communication member 49 to the thin film side and the breakage of the thin film by the communication member 49 are allowed.
- the shape of 51 and 52 and the number of thin portions are not particularly limited, but the number of thin portions in the portion Z is due to the fact that the bridge breaks due to the small number of thin portions or the number of thin portions is too large. From the viewpoint of preventing the bending from becoming complicated, it is preferably three.
- the bridge 49a is bent and deformed when a force is applied to the communication member 49 to the thin film side by pressing, and the thin film may be broken while the cap body portion and the communication member are connected. Since it can do, it can prevent reliably that a communicating member falls in a container main-body part, and a communicating member floats in a liquid substance, but in this embodiment, it may fracture
- cap and the nutrient solution container of the present embodiment may include the protective cover described in the second embodiment.
- a liquid feeding circuit connected to or constituting a nutrient supply set together with a nutrient container is a flow rate regulator for pressing the flexible tube 26 and adjusting the flow rate of the liquid material flowing through the flexible tube 26.
- the present invention can provide a nutrient container cap suitable for enteral nutrition therapy, a nutrient container using the same, and a nutrient supply set including the nutrient container.
