Another example is disclosed in Japanese Patent Laid-Open No. 2003-305107 (Patent Document 2).
In the thing of Unexamined-Japanese-Patent No. 2003-305107, as shown to the Fig.8 (a), in the chemical | medical agent discharge member of a medical multi-chamber container, the one end part of the main-body part is equipped with the communication part, The first tube portion connected to the main body portion and the second tube portion connected to the first tube portion and having an outer peripheral surface formed in a tapered shape, the tip of the second tube portion being sealed with a lid member. A plurality of communication holes communicating with the inside are formed on the outer peripheral surface of the second pipe portion. Moreover, this communication part is connected to the container main body. For this reason, the peripheral part of a container main body is heat-seal | fused to the outer peripheral surface of a 1st pipe part and a 2nd pipe part. The peripheral edge of the container body is firmly fused to the first tube portion to form a strong seal portion, while the second tube portion is weaker than this and melted with a stronger strength than the weak seal portion for partition. The weak seal part (adhesion part) to be worn is configured. And after pressing a 1st storage chamber and opening the weak seal part for a partition, the whole storage chamber connected is pressed. That is, as shown in FIG. 8B of Japanese Patent Laid-Open No. 2003-305107, the weak seal part is peeled off from the second pipe part when the pressure in the storage chamber increases. Thereby, the chemical | medical agent in a storage chamber flows in in a main-body part via a communicating hole. In addition, since the strong seal part is firmly fused to the first pipe part, the medicine does not flow out from this part.
