Abstract
A tray for uniformly mixing fluent material contained within a plurality of vessels, the tray having a restraining plate, restraining the vessels at a first location thereof against movement, and a vessel engaging element arranged to engage the plurality of vessels at a second location thereof and being spaced away from and rotatably movable relative to the restraining plate for shaking all the vessels over a uniform path when the vessels are thereby engaged and restrained. The frequency of shaking is adjustable and its duration can be set for a specific period of time.
Claims15
A holder for uniformly mixing fluent material contained within a plurality of vessels, the holder comprising:
- restraining means including a restraining plate arranged for restraining a plurality of vessels at a first location thereof against movement;
- vessel engaging means including a vessel engaging plate arranged to engage the plurality of vessels at a second location thereof and spaced away from and rotatably movable relative to said restraining means for shaking all the vessels over a uniform path when the vessels are thereby engaged and restrained by said vessel engaging plate and said restraining plate respectively;
- and
- means for flexibly connecting said engaging and restraining plates together so as to allow movement of said engaging plate relative to said restraining plate, said flexibly connecting means including at least one flexible connecting rod connected at one end thereof with said engaging plate and at another end thereof with said restraining plate.
A tray for uniformly mixing fluent material contained within a plurality of vessels, the tray comprising:
- restraining means arranged for restraining a plurality of vessels at a first location thereof against movement;
- a vessel engaging element arranged to engage the plurality of vessels at a second location thereof and spaced away from and rotatably movable relative to said restraining means for shaking all the vessels over a uniform path when the vessels are thereby engaged and restrained by said vessel engaging element and said restraining means respectively, said restraining means including a restraining plate with a first plurality of holes, through which the vessels are insertable, said restraining plate having a bottom surface;
- and
- retaining means including a layer of resilient material on said bottom surface, said layer having a second plurality of holes aligned with and having a diameter smaller than that of said first plurality of holes in said restraining plate so that when said vessels are inserted through said first and said second pluralities of holes, the said layer of resilient material forming said second plurality of holes contacts and retains the vessels.
A tray for uniformly mixing fluent material contained within a plurality of vessels, the tray comprising:
- restraining means arranged for restraining a plurality of vessels at a first location thereof against movement;
- vessel engaging means arranged to engage the plurality of vessels at a second location thereof and spaced away from and rotatably movable relative to said restraining means for shaking all the vessels over a uniform path when the vessels are thereby engaged and restrained by said vessel engaging means and said restraining means respectively, said vessel engaging means including an engaging plate, said restraining means including a restraining plate;
- and
- means for flexibly connecting said engaging and restraining plates together so as to allow movement of said engaging plate relative to said restraining plate, said flexibly connecting means including at least one clamp member releasably fastened to one of said plates said flexibly connecting means further including at least one flexible connecting rod secured to the other of said plates and extending to said clamp member fastened to said one of said plates, said flexible connecting rod and said clamp member being formed so that said flexible connecting rod is held into position by said clamp member when said clamp member is tightened to fix a relative distance between said plates and so that said flexible connecting rod is released when said clamp member is loosened to permit movement of said plates relative to each other so that said relative distance corresponds to a height of the vessels to be restrained and engaged.
