- the reinforcing film 20 can be uniformly bonded to each of the seal portions regardless of the degree of swelling of the seal portions in the thickness direction 23 of the first accommodating portion 11.
- the chemical liquid side weak seal part 17 acts in the discharge direction 14 with respect to the chemical liquid side weak seal part 17 because there is no reinforcing film to be bonded from the chemical liquid side strong seal part 17 to the second housing part 12 side. For pressure, no reinforcing effect is produced. That is, the original peel strength of the weak seal portion is maintained with respect to the pressure that presses the second storage portion 12 and acts on the chemical liquid side weak seal portion 17 in the discharge direction 14.
- the medical multi-chamber container for example, when the second container 12 is pressed to open the liquid side weak seal 17, the first container 11 and the second container 12 are separated. It is possible to prevent a situation where the discharge side weak seal portion 18 is opened before the contained medicines are sufficiently mixed with each other.
- the discharge port 27 for discharging the drug disposed in the discharge-side strong seal portion 18 is for discharging the drug stored in the medical multi-chamber container 10 to the outside of the medical multi-chamber container.
- the member is not particularly limited, and generally includes a discharge port used for a medical container.
- the discharge side weak seal portion 18 is easily opened by the pressure acting on the discharge side weak seal portion 18 when the discharge side weak seal portion 18 is opened.
- Easy-to-open part 32 is provided. [0055]
- the easy-open portion 32 is provided in the center portion in the width direction 15 of the discharge side weak seal portion 18 (see Fig. 1), and the discharge side weak seal portion 18 is directed toward the chemical solution side weak seal portion 17 side. It is formed in a generally V-shape protruding in plan view.
- the easy-opening portion 32 includes a protruding portion 33 in which the discharge side weak seal portion 18 protrudes toward the upstream side in the discharging direction 14, and of the protruding portion 33 at the upstream end portion in the discharging direction 14.
- the boundary edge (second boundary edge) 34 with the empty accommodating portion 13 is more in the discharge direction 14 than the first boundary edge 19 with the first accommodating portion 11 in the discharge side weak seal portion 18 adjacent to the protruding portion 33. Arranged upstream.
- the easy-open portion 32 shown in FIGS. 6 (a) and 6 (b) has a boundary edge with the empty accommodating portion 13 at the end of the protruding portion 33 on the upstream side in the discharge direction 14 (second 34) is disposed upstream of the first boundary edge 19 of the first accommodating portion 11 in the discharge side weak seal portion 18 adjacent to the projecting portion 33, and is upstream of the discharge direction.
- the seal part 18 can be opened more reliably.

- the second boundary edge 34 with the empty accommodating portion 13 is located at the upstream end in the discharge direction 14 of the protrusion 33, and the discharge side weakly adjacent to the protrusion 33. Since the seal portion 18 is disposed upstream of the first boundary edge 19 with the first accommodating portion 11 in the discharge direction 14, pressure is exerted on the discharge side weak seal portion 18 in the discharge direction 14. Sometimes, the pressure can be concentrated and applied to the easy-opening portion 32b, and the discharge-side weak seal portion 18 can be reliably opened.
- a total of three easy-open portions 32 are provided at substantially equal intervals in the width direction 15 of the discharge-side weak seal portion 18.
