| 摘要 |
The present invention relates to devices for dispensing and mixing multi-component materials, in particular for viscous fluid materials. The device is adapted for dispensing multi-component compositions that are kept separate prior to use and that are also typically mixed prior to use to properly combine the constituents in order to form an active and/or working composition. In one embodiment, a device is adapted to contain at least one vessel containing a material prior to use. The device also includes a mechanism for evacuating the at least one vessel and a mechanism for mixing at least one material prior to use. The material may contain multiple constituents in one vessel or more than one vessel. |
