Welding-wire-storing pail pack, container for pail pack, and pressing member for pail pack
A welding-wire-storing pail pack is provided in which a pressing member includes an annular body positioned on a coil of welding wire, a pressing margin extending from a position on an underside of the body at an inner peripheral edge of the coil toward an axis of the coil, and a projection provided on an inner peripheral edge of the pressing margin in such a manner as to project downward. The body has an inner diameter of 200 to 470 mm. A gap of 10 mm at the minimum is provided between an inner shell and the body. The pressing member weighs 600 to 2000 g. Thus, the wire is prevented from being tangled and/or kinked when being pulled out, and the occurrence of decoiling failure is prevented.
1. A welding-wire-storing pail pack comprising:
a container in which an inner shell and an outer shell are coaxially provided on a bottom plate;
a coil of welding wire stored in a space between the inner shell and the outer shell; and
a pressing member provided on the coil of welding wire for preventing the welding wire from jumping when the welding wire is decoiled, due to the weight of the pressing member on the coil,
wherein the welding wire is used by being pulled out of a gap between the pressing member and the inner shell,
wherein the pressing member includes
an annular body positioned on the welding wire;
a pressing margin of the annular body extending from a position on an underside of the annular body at an inner peripheral edge of the coil toward an axis of the coil; and
a projection provided on an inner peripheral edge of the pressing margin in such a manner as to project downward from the pressing margin by a certain length in the direction of the axis of the annular body,
wherein the annular body of the pressing member has an inner diameter of 200 to 470 mm,
wherein the gap has a minimum width of 10 mm,
wherein the pressing member weighs 600 to 2000 g,
wherein the pressing margin has a width of 5 to 135 mm, and
wherein the certain length of the projection is 0.3 to 1.5 mm, and a width of the projection in the direction of the diameter of the annular body is 1 to 10 mm.
2. The welding-wire-storing pail pack according to claim 1 , wherein the annular body of the pressing member is flat in the entirety thereof.
3. The welding-wire-storing pail pack according to claim 1 , wherein the annular body of the pressing member includes a flat portion and a barrier portion, the barrier portion being raised from an outer periphery of the flat portion and having a step-like shape with a lower portion thereof having a smaller diameter than an upper portion thereof.
4. The welding-wire-storing pail pack according to claim 1 , wherein the projection of the pressing member has a curved projecting surface.
5. The welding-wire-storing pail pack according to claim 1 , wherein the projection of the pressing member has, on a side thereof nearer a center axis of the coil, a sloping surface whose inner diameter becomes smaller from the bottom to the top thereof in the direction of the axis of the annular body.
6. A pressing member intended for pressing a coiled welding wire stored in a container in which an inner shell and an outer shell are coaxially provided on a bottom plate, wherein the coiled wire is stored between the inner shell and an outer shell, the pressing member comprising:
an annular body adapted to be positioned on the welding wire, wherein a pressing margin of the annular body extends from a position on an underside of the annular body at an inner peripheral edge of the coil toward an axis of the coil; and
a projection provided on an inner peripheral edge of the pressing margin in such a manner as to project downward from the pressing margin by a certain length in the direction of the axis of the annular body,
wherein the annular body of the pressing member has an inner diameter of 200 to 470 mm,
wherein a gap between the inner periphery of the annular body and the inner shell has a minimum width of 10 mm,
wherein the pressing member weighs 600 to 2000 g,
wherein the pressing margin has a width of 5 to 135 mm, and
wherein the certain length of the projection is 0.3 to 1.5 mm, and a width of the projection in the direction of the diameter of the annular body is 1 to 10 mm.
