Vessel with retention features and method therefor
A vessel with retention features for the retention of pellets for use in laboratory processes, manufacturing, and producing packaged foods, chemicals, and medicines.
1. A collection device comprising:
an elongate tubular container having an open end, the container defined in part by an inner surface and an outer surface, the container adapted to receive a mixture of substances, the mixture including a desired sample material;
one or more retention projections disposed along the inner surface of the container, the one or more retention projections extending out from the inner surface of the container, the one or more retention projections adapted to retain the desired sample material within the container; and
the one or more retention projections include two or more retention projections defined by a height, including a first projection with a first height and a second projection having a second height, and the first height is different than the second height.
2. The collection device as recited in claim 1 , wherein a plurality of retention projections are disposed on the inner surface.
3. The collection device as recited in claim 1 , wherein the one or more retention projections have a triangular cross-sectional shape.
4. The collection device as recited in claim 1 , wherein the one or more retention projections include at least one substantially flat side surface.
5. A collection device comprising:
an elongate tubular container extending from a first open end to a second closed end, the tubular container defined in part by an inner surface and an outer surface;
one or more retention projections disposed adjacent to the second closed end of the container, the one or more retention projections disposed on the inner surface of the container and extending outward from the inner surface, the one or more retention projections adapted to retain a desired sample material within the container; and
the one or more retention projections include two or more retention projections defined by a height, including a first projection with a first height and a second projection having a second height, and the first height is different than the second height.
6. The collection device as recited in claim 5 , wherein the one or more retention projections include groups of retention projections, wherein the groups of retention projections are spaced apart from one another.
7. The collection device as recited in claim 5 , wherein the second closed end has a generally conical shape and the one or more retention projections are disposed within the conical shape.
8. The collection device as recited in claim 7 , wherein the generally conical shape includes a generally flat end portion, and the one or more retention projections are disposed on the generally flat end portion.
9. The collection device as recited in claim 5 , wherein the one or more retention projections include at least one substantially flat side surface.
10. A method of collecting a sample comprising:
disposing a mixture including a desired sample material within an elongate tubular container, the container extending from a first open end to a second closed end, the container defined in part by an inner surface and an outer surface, one or more retention projections disposed on the inner surface of the container, the one or more retention projections extending outward from the inner surface and are adapted to retain the desired sample material disposed within the container;
pouring the mixture from the first open end of the container; and
retaining the desired sample material with the one or more retention projections.
11. The method as recited in claim 10 , wherein retaining the desired sample material includes retaining the desired sample material with retention projections having a triangular cross-section.
12. The method as recited in claim 10 , further comprising centrifuging the container prior to pouring the mixture from the first open end of the container.
13. The method as recited in claim 10 , wherein retaining the desired sample material includes retaining the desired sample material with retention projections having at least one substantially flat side surface.
14. The method as recited in claim 10 , wherein retaining the desired sample material includes retaining the desired sample material with groups of retention projections that are spaced apart from each other.
15. A method of forming a vessel comprising:
forming an elongate, tubular vessel with an open portion and a closed portion, the vessel defined in part by an inner surface and an outer surface; and
forming one or more retention projections on the inner surface of the vessel, including projecting the one or more retention projections out from the inner surface of the vessel, including forming at least a first retention projection and a second retention projection, and forming the first retention projection with a different height than the second retention projection.
16. The method as recited in claim 15 , wherein forming the one or more retention projections includes forming at least one substantially flat side surface on at least one of the one or more retention projections.
17. The method as recited in claim 15 , wherein forming the one or more retention projections includes forming the one or more retention projections on a conical portion of the vessel adjacent the closed portion of the vessel.
18. The method as recited in claim 15 , wherein forming the one or more retention projections includes forming the one or more retention projections on a substantially flat end portion of the vessel adjacent the closed portion of the vessel.
19. The method as recited in claim 15 , wherein forming the one or more retention projections includes forming groups of retention projections, and spacing the groups of retention projections apart from one another.
20. A collection device comprising:
a tubular container extending from a first open end to a second closed end, the tubular container defined in part by an inner surface and an outer surface; and
one or more retention projections disposed adjacent to the second closed end of the container, the one or more retention projections disposed on the inner surface of the container and extending outward from the inner surface, wherein the one or more retention projections include two or more retention projections defined by a height, including a first projection with a first height and a second projection having a second height, and the first height is different than the second height.
21. A method of collecting a sample comprising:
disposing a mixture including a desired sample material within a container, the container extending from a first open end to a second closed end, the container defined in part by an inner surface and an outer surface, one or more retention projections disposed on the inner surface of the container, the one or more retention projections extending outward from the inner surface and are adapted to retain the desired sample material disposed within the container;
centrifuging the container;
pouring the mixture from the first open end of the container after centrifuging the container; and
retaining the desired sample material with the one or more retention projections.
