A tier sheet for supporting a plurality of containers disposed in rows on the tier sheet and for supporting and separating a plurality of tiers of the containers to provide a tiered stack of the containers. Projections at the edge portions of the tier sheet extend from and above an upper surface and extend from and below a lower surface of the tier sheet sufficiently to impede lateral movement of an outside container disposed at an outside row from displacing the outside container from the stack.
1. In a tier sheet for supporting a plurality of containers disposed in rows on the tier sheet and for supporting and separating a plurality of tiers of the containers to provide a tiered stack of the containers, said tier sheet having a perimeter, the improvement comprising:
a plurality of rows of discontinuous projections at edge portions of the tier sheet extending from and above an upper surface and extending from and below a lower surface of the tier sheet sufficiently to impede lateral movement of an outside container disposed at an outside row from displacing the outside container from the stack, said plurality of rows spaced a distance away from said edge portion around said perimeter of said tier sheet, wherein said plurality of rows do not extend into an interior planar section of the tier sheet.
2. The tier sheet of claim 1 , wherein on an opposite surface of an edge portion from a projection there is an opposite depression in the edge portion.
3. The tier sheet of claim 2 , wherein the projection and opposite depression are in the form of a score line in the surfaces.
4. The tier sheet of claim 1 , wherein the edge portion has a width of at least 0.5 inch.
5. The tier sheet of claim 4 , wherein the width is at least 1.0 inch.
6. The tier sheet of claim 1 , wherein the tier sheet is made of a material selected from the group consisting of fiberboard, plastic, kraft board and chip board.
7. The tier sheet of claim 1 , wherein the tier sheet has lateral edge dimensions of from 18 to 60 inches and a thickness of from 0.03 to 0.3 inch.
8. The tier sheet of claim 1 , wherein the tier sheet contains a bactericide or an insecticide.
9. The tier sheet of claim 8 , wherein the bactericide or insecticide is coated on the tier sheet.
10. A sheet for use with shipping material containers comprising:
a sheet having an upper and lower surface, each defining a plane, said sheet having a perimeter; and
a plurality of rows of discontinuous projections extending from each of the upper and lower surface, each of said projections extending beyond said plane thereof, each of said plurality of rows disposed a distance from and around said perimeter wherein the plurality of rows does not extend into an interior planar section of the sheet.
11. A sheet for use with shipping multiple containers comprising:
a sheet having a width and an upper and lower surface, each surface defining a plane; and
a plurality of rows of discontinuous depressions extending beyond each of the upper and lower surface, the plurality of rows extending into the width of the sheet, wherein the plurality of rows do not extend into an interior planar section of the sheet.
12. In a tier sheet for supporting a plurality of containers disposed in rows on the tier sheet and for supporting and separating a plurality of tiers of the containers to provide a tiered stack of the containers, said tier sheet having a perimeter, the improvement comprising:
a plurality of rows of discontinuous projections at edge portions of the tier sheet extending from and above an upper surface extending from and below a lower surface of the tier sheet sufficiently to impede lateral movement of an outside container disposed at an outside row from displacing the outside container from the stack,
wherein the plurality of rows is spaced a distance away from said edge portion and around said perimeter of said tier sheet; and
wherein the plurality of rows is multi-directional.
13. The tier sheet of claim 12 , wherein the plurality of rows does not extend into an interior planar section of the tier sheet.
