摘要：
A unit dose package for a dental composition, comprising:(a) a rigid support member having a proximal end and a distal end, the rigid support member supporting one or more storage compartments for the dental composition and providing fluid flow communication between the one or more storage compartments and one or more discharge orifices, wherein the one or more storage compartments each have a volume of 10 μl to 1000 μl, and(b) a discharge conduit having a longitudinal axis extending from a proximal end to a distal end, the discharge conduit being rotatably attached to the distal end of the rigid support member for rotation around its longitudinal axis,wherein the attachment of the discharge conduit (b) and the rigid support member (a) is provided by two-component injection molding；whereby fluid flow communication between the discharge conduit and the one or more storage compartments may be established by rotating the discharge conduit around its longitudinal axis relative to the rigid support member from a first position to a second position and whereby the fluid flow communication between the discharge conduit and the one or more storage compartments may be interrupted by rotating the discharge conduit around its longitudinal axis relative to the rigid support member from the second position to the first position, wherein the one or more storage compartments are provided by flexible films made of composite material films, which are attached to the rigid support member.
