Crush-can with corrugated core
A crush-can is provided. That crush-can includes a first wall, a second wall within the first wall and a corrugated core between the first wall and the second wall. A method for producing the crush-can via 3D printing is also disclosed.
1. A crush-can, comprising:
a first wall, wherein said first wall is frustoconical in shape;
a second wall within said first wall; and
a corrugated core between said first wall and said second wall.
2. The crush-can of claim 1 , wherein said second wall is frustoconical in shape.
3. The crush-can of claim 1 , further including a first end element closing a first end of said crush-can.
4. The crush-can of claim 3 , further including a second end element closing a second end of said crush-can.
5. The crush-can of claim 4 , wherein said corrugated core has a width between said first wall and said second wall of between about 2.0 mm and about 3.0 mm.
6. The crush-can of claim 5 , wherein said first wall has a thickness of between about 0.1 mm and about 0.2 mm.
7. The crush-can of claim 6 , wherein said second wall has a thickness of about 0.1 mm and about 0.2 mm.
8. The crush-can of claim 7 , wherein said crush-can is flangeless.
9. The crush-can of claim 1 , further including a third wall within said second wall and a second corrugated core between said second wall and said third wall.
10. The crush-can of claim 9 , wherein said third wall is frustoconical in shape.
11. The crush-can of claim 10 , further including a first end element closing a first end of said crush-can.
12. The crush-can of claim 11 , further including a second end element closing a second end of said crush-can.
13. The crush-can of claim 12 , wherein said corrugated core has a width between said first wall and said second wall of between about 2.0 mm and about 3.0 mm.
14. The crush-can of claim 13 , wherein said second corrugated core has a width between said second wall and said third wall of between about 2.0 mm and about 3.0 mm.
15. A method of producing a crush-can, comprising:
3D printing a unitary crush-can body including a first wall having a frustoconical shape, a second wall within said first wall and a corrugated core between said first wall and said second wall.
16. The method of claim 15 , including closing a first end of said crush-can body with a first end element.
17. The method of claim 16 including closing a second end of said crush-can body with a second end element.
18. The method of claim 15 including 3D printing first and second end elements with said crush-can body as a part of a unitary construction.
19. A crush-can, comprising:
a first wall;
a second wall within said first wall, wherein said second wall is frustoconical in shape; and
a corrugated core between said first wall and said second wall.
