Welding consumable container with protective open rim
A container having a wall, where the wall includes a score line that defines a removable lid, where the score line defines the perimeter of the lid. The container lid includes a protective component extending inwardly of the perimeter of the lid and covering a sharp edge of a burr formed by removing the lid from the wall.
1. A container lid comprising:
at least one side wall that defines a volume for receiving at least one welding consumable;
an end wall connected to the at least one sidewall, the end wall enclosing the at least one welding consumable within the volume;
a score line formed in a surface of the end wall defining a perimeter of a container lid, wherein at least a portion of the container lid is removable from the end wall by tearing the container lid along the score line, and wherein the score line forms a burr upon tearing; and
a protective element attached to a surface of the end wall, the protective element extending inward relative to the at least one sidewall to cover the burr, and wherein the protective element comprises a label on the end wall, the label covering the container lid and extending radially outward of the perimeter of the container lid to attach to the end wall outside of the container lid, the label defining a second score line located radially inward relative to the first score line, wherein the label tears along the second score line leaving a flexible lip extending inward of the first score line to cover the burr.
2. The container lid of claim 1 , wherein the second score line is formed continuously.
3. The container lid of claims 1 , wherein the label is attached to the end wall with an adhesive.
4. The container lid of claim 1 , wherein the label is made from a high density spunbonded olefin film.
5. The container lid of claim 1 , wherein the label is made from a laminate structure including a paper layer and a polyester layer.
6. The container lid of claim 1 further comprising a handle attached to the end wall.
7. The container lid of claim 6 , wherein the handle is a pull tab.
8. The container lid of claim 1 wherein the protective element includes a rolled edge formed at a perimeter of the wall.
9. The container lid of claim 1 , wherein the label is on an opposite surface of the end wall relative to the surface of the end wall in which the score line is formed.
10. The container lid of claim 1 , wherein the end wall includes an inner surface and an outer surface, wherein the score line is formed in the outer surface of the end wall, and wherein the label is applied to the inner surface of the end wall.
11. A container comprising:
a wall defining an enclosed volume;
a first score line formed in a surface of the wall, the score line defining a perimeter of a removable container lid;
a label attached to the wall covering the container lid and extending outward of the score line; and
wherein the label defines a second score line located inward of the first score line, wherein removal of the container lid tears the label along the second score line leaving a portion of the label attached to the wall and extending inward of the edge of the end wall to form a protective element.
12. The container of claim 11 , wherein the wall includes a sidewall and an end wall that are attached to each other to form the enclosed volume; wherein the first score line is formed in an outer surface of the end wall and the label is attached to an inner surface of the end wall.
13. The container of claim 12 , wherein the second score line is formed on an outer surface of the label.
14. The container of claim 12 , wherein the end wall is sealingly attached to the at least one side wall to seal the volume.
15. The container of claim 11 , wherein the label is made from flexible film.
16. The container of claim 11 , wherein the label is made a high density spunbonded olefin film.
17. The container of claim 11 further comprising a handle attached to the container lid.
18. The container of claim 17 , wherein the handle is a pull tab.
19. The container of claim 11 , wherein the label is attached with a layer of adhesive.
20. The container of claim 11 , wherein the first and second score line are continuous.
21. A container comprising:
at least one side wall defining a volume;
a welding consumable received within the volume of the container,
an end wall attached to the side wall by a rolled edge to enclose the welding consumable within the volume,
the rolled edge defining a first bend that extends radially inward from the side wall forming an inward extremity;
a first score line formed on an inner surface of the end wall, the first score line having a cross-sectional profile that tapers inward as it extends outward from the inner surface of the end wall;
wherein the first score line defines a perimeter of a removable container lid, the first score line being located radially outward of the inward extremity of the rolled edge, such that when the container lid is removed from the end wall a portion of the end wall remains radially outward of the inward extremity of the rolled edge; wherein removal of the container lid forms an edge at the end wall, the edge defining an opening through which the welding consumable is accessed; and
a label attached to the end wall covering the container lid and extending outward of the perimeter of the container lid, a second score line formed in the label inward of the first score line; wherein removal of the container lid tears the label along the second score line leaving a portion of the label attached to the end portion and extending inward over a portion of the opening to form a protective element that extends inward of the edge of the end wall.
