Vessel and process for production thereof
First Claim
1. A vessel for carrying out chemical or biochemical reactions, said vessel comprising:
- a malleable or mouldable material, the vessel having one or more side walls and a closed base integral with said one or more side walls, the one or more side walls defining an upper portion and a lower portion of relatively smaller cross sectional area having a tapering profile, the upper portion having an opening;
a reagent chamber in the lower portion;
two or more projections located in an area of a junction between the upper and lower portions, said two or more projections extending into an interior of the vessel, generally laterally from said one or more side walls, wherein said projections are also integral with said side wall; and
a freeze dried reagent retained within a region located below the projections, the projections forming a restraint that prevents the freeze dried reagent being displaced within the vessel or exiting through the opening in the upper portion.

Abstract
A vessel of a malleable or moldable material having one or more side walls and a closed base integral with said one or more side walls, an opening in the top of the vessel, and further comprising two or more projections extending into the interior of the vessel generally laterally from said side walls, wherein said projections are also integral with said side wall. Vessels of this type are produced by a process in which ridges are deformed into projections within a vessel blank, and this process forms a further aspect of the invention. They are particularly useful for holding solid masses such as small beads or cakes in position in the vessel.
