Abstract

A multiple-chamber medical container 1 comprises a container body 5 having two chambers 9, 11 for containing medicaments therein and a partitioning weak seal portion 13 for separating the chambers 9, 11 from each other, a medicinal outlet portion 7 attached to the container body 5 for discharging the medicaments from the chambers therethrough, and an openable small container 15 disposed in the first chamber 9 and having a medicament enclosed therein, the partitioning seal portion 15 being openable so as to cause the chambers 9, 11 to communicate with each other for use. The small container 15 can be opened by opening the partitioning weak seal portion 13.

Claims

1. A multiple-chamber medical container comprising:

a container body having the chambers for containing medicaments therein and a partitioning seal portion for separating the chambers from one another,

a medicinal outlet portion attached to the container body for discharging the medicaments from the chambers therethrough, and

an openable small container formed with sheet material disposed in at least one of the chambers and having a medicament enclosed therein;

the partitioning seal portion being openable so as to cause the chambers to communicate with one another for use,

the partitioning seal portion being formed by bonding opposed inner wall surfaces of the container body separably,

the sheet material forming the small container being bonded to the opposed inner wall surfaces of the container body in the vicinity of the partitioning seal portion,

the small container opening in accordance with the separation of the inner wall surfaces caused by opening the partitioning seal portion.

5. A multiple-chamber medical container according to claim 1, wherein the distance between the small container and the partitioning seal portion is 0 to 50 mm.

6. A multiple-chamber medical container according to claim 1 wherein,

the small container is heat-sealed at at least one portion of a peripheral edge thereof,

the sealed portion being openable by external force,

a nonbonded portion of the small container inwardly of the sealed portion of the peripheral edge having a bonded portion bonded to the inner wall surfaces of the chamber.

7. A multiple-chamber medical container according to claim 1, wherein the bonded portion of the small container comprises a plurality of bonded parts arranged with at least one nonbonded part positioned therebetween.

8. A multiple-chamber medical container according to claim 7, wherein said at least one nonbonded part is provided in the vicinity of the center of the bonded portion.

9. A multiple-chamber medical container according to claim 1, wherein the sheet material of the small container comprises a multilayer film and the small container is opened by delaminating the multilayer film.

10. A multiple-chamber medical container according to claim 9, wherein the sheet material of the small container comprises a multilayer film formed by laminating a plurality of resin layers having low miscibility with one another.

11. A multiple-chamber medical container according to claim 1, wherein the sheet material of the small container is at least partly heat-sealed, the sealed portion being openable by an external force.

12. A multiple-chamber medical container according to claim 1, wherein the small container is disposed in at least one of the chambers to thereby accommodate the medicament in the chamber.

13. A multiple-chamber medical container according to claim 12, wherein the medicinal outlet portion is connected to the chamber having the small container disposed therein.

14. A multiple-chamber medical container according to claim 1, wherein a discharge-control seal portion is further provided as an openable partition between the medicinal outlet portion and the chamber.

15. A multiple-chamber medical container according to claim 1, wherein a medicament selected from among an antibiotic, anticancer drug, cardiotonic drug, vitamin and trace element is enclosed in the small container.

16. A bag for enclosing therein at least one multiple-chamber medical container according to claim 1, wherein

the bonded portion of the small container is provided approximately in parallel to the partitioning seal portion, and

the medical container is folded along an edge of the bonded portion on one side thereof opposite to the partitioning seal portion before being placed into the bag.

3. A multiple-chamber comprising:

a container body having the chambers for containing medicaments therein and a partitioning seal portion for separating the chambers from one another,

a medicinal outlet portion attached to the container body for discharging the medicaments from the chambers therethrough, and

an openable small container formed with sheet material disposed in at least one of the chambers and having a medicament enclosed therein,

the partitioning seal portion being openable so as to cause the chambers to communicate with one another for use,

the partitioning seal portion being formed by bonding opposed inner wall surfaces of the container body separably,

the sheet material forming the small container being bonded to the inner wall surfaces within the partition seal portion, and

the small container opening in accordance with the separation of the inner wall surfaces caused by opening the partitioning seal portion.

17. A multiple-chamber medical container according to claim 3, wherein the sheet material of the small container comprises a multilayer film and the small container is opened by delaminating the multilayer film.

18. A multiple-chamber medical container according to claim 17, wherein the sheet material of the small container comprises a multilayer film formed by laminating a plurality of resin layers having low miscibility with one another.

19. A multiple-chamber medical container according to claim 3, wherein the sheet material of the small container is at least partly heat-sealed, the sealed portion being openable by an external force.

20. A multiple-chamber medical container according to claim 3, wherein the small container is disposed in at least one of the chambers to thereby accommodate the medicament in the chamber.

21. A multiple-chamber medical container according to claim 20, wherein the medicinal outlet portion is connected to the chamber having the small container disposed therein.

22. A multiple-chamber medical container according to claim 3, wherein a discharge-control seal portion is further provided as an openable partition between the medicinal outlet portion and the chamber.

23. A multiple-chamber medical container according to claim 3, wherein a medicament selected from among an antibiotic, anticancer drug, cardiotonic drug, vitamin and trace element is enclosed in the small container.

24. A bag for enclosing therein at least one multiple-chamber medical container according to claim 3, wherein
