Before-use mixing container

Abstract

The present invention provides a before-use mixing container in which it is possible to perform a mixing operation for two types of medicinal solutions in its container independently of an uncovering operation for a cap or the like. The before-use mixing container including a movable body 1 which has a tube section 11 , a ceiled cylindrical inner tube 13 which is consecutively installed upright on an inner surface of the tube section, that partitions the tube section into two upper and lower chambers, and a first opening portion 13 b drilled in a ceiling plane 13 a of the inner tube, and in which a first medicinal solution A is contained in the lower chamber, an adapter 3 which has a fit-in tube section 31 which is tightly fit into the upper chamber of the movable body to be assembled so as to be rotatable with respect to the movable body, a partition wall surface 35 which is provided on an inner surface of the fit-in tube section, and is tightly attached to the ceiling plane of the inner tube of the movable body, and a second opening portion 35 a which is drilled in the partition wall surface so as not to overlap the first opening portion, and a container main body 4 which has a lower mouth tube section 42 tightly fit into the upper chamber of the adapter, to be assembled so as not to be rotatable with respect to the adapter, and in which a second medicinal solution B is contained, in the before-use mixing container, when the movable body is relatively rotated with respect to the container main body, the first opening portion and the second opening portion are overlapped.

1 . A before-use mixing container comprising:
 a movable body which has a bottomed cylindrical tube section, a ceiled cylindrical inner tube which is consecutively installed upright on an inner side in a circumferential direction from an inner surface of the tube section, that partitions an internal space of the tube section into two upper and lower chambers, and a first opening portion drilled in a ceiling plane of the inner tube, and in which a first medicinal solution is contained in the lower chamber;   an adapter which has a hollow cylindrical fit-in tube section which is tightly fit into the upper chamber of the movable body to be assembled so as to be rotatable with respect to the movable body, a partition wall surface which is provided on an inner surface of the fit-in tube section, and is tightly attached to the ceiling plane of the inner tube of the movable body in a state in which the partition wall is assembled to the movable body, and a second opening portion which is drilled in the partition wall surface so as not to overlap the first opening portion; and   a container main body which has a lower mouth tube section which is tightly fit into the upper chamber surrounded by an upper surface of the partition wall surface of the adapter and the inner surface of the fit-in tube section, to be assembled so as not to be rotatable with respect to the adapter, and in which a second medicinal solution is contained, wherein   when the movable body is relatively rotated with respect to the container main body, the first opening portion of the movable body and the second opening portion of the adapter are overlapped, and the container is capable of mixing the first medicinal solution and the second medicinal solution before use.   
     
     
         2 . The before-use mixing container according to  claim 1 , wherein
 the fit-in tube section of the adapter is provided with a large diameter section and a small diameter section having circular arc shapes in plan view, and in a state in which the fit-in tube section of the adapter is assembled to the upper chamber of the movable body, the large diameter section and the small diameter section of the fit-in tube section are respectively spaced from the inner surface of the tube section of the movable body to generate gaps, and   a vertical line with a height exceeding a spaced distance between the inner surface of the tube section and the large diameter section, and with a height which does not exceed a spaced distance between the inner surface of the tube section and the small diameter section is provided on the inner surface of the tube section of the movable body, and the longitudinal vertical line faces the small diameter section.   
     
     
         3 . The before-use mixing container according to  claim 2 , wherein, when the movable body is relatively rotated with respect to the container main body and the vertical line provided on the inner surface of the tube section of the movable body reaches a boundary portion between the small diameter section and the large diameter section of the fit-in tube section, the first opening portion and the second opening portion are overlapped.
