Abstract

A welding wire packaging container of mono-cylinder pail type accommodating a welding wire winding which includes of a multitude of layers of looped wire portions having diameters smaller than the inside diameter of the container and centrally having a cavity of substantially cylindrical form. The container includes a retaining member placed on overlying layers of wire loops and adapted to be lowered by gravity as the wire is withdrawn from the container, the retaining member being centrally formed with a circular wire guide hole to permit wire withdrawal therethrough, and resilient members mounted at least two spaced positions around the outer periphery of the retaining member for contact with the inner wall surface of the container, the guide hole in the retaining member being located in vertically spaced relation with an upper lid of the container.

Claims10

Dependent claims

A wire packaging container comprising:

(a) a bottom portion in the form of a mono-cylinder pail having substantially no inner cylinder and having a bottom;
(b) a multitude of layers of looped wire portions disposed in said bottom portion, said layers having outer diameters smaller than the inside diameter of said bottom portion and inside diameters which define a central cavity of substantially cylindrical form;
(c) a vertically movable retaining member loosely disposed within said bottom portion on top of said layers, said retaining member being in the form of a flat ring the bottom surface of which bears against said layers, the outer surface of which is adjacent the inner surface of said bottom portion, and the inner surface of which has an inside diameter which is smaller than the inside diameter of said layers, whereby the wire may be withdrawn along the inner peripheral edge of said retaining member, thereby ensuring withdrawal of the wire against substantially constant resistance without disturbing lower layers of the wire or causing snarling;
and
(d) a plurality of resilient members mounted on said retaining members, said resilient members containing the inner surface of said bottom portion but permitting said retaining member to move downwardly in said bottom portion under the force of gravity as the wire is withdrawn.

A wire packaging container comprising:

(a) a bottom portion in the form of a cylinder having a bottom;
(b) a multitude of layers of looped wire portions disposed in said bottom portion, said layers having outer diameters smaller than the inside diameter of said bottom portion and inside diameters which define a central cavity of substantially cylindrical form;
(c) an upper lid disposed on said bottom portion;
(d) a retaining member disposed within said bottom portion on top of said layers and beneath said upper lid, said retaining member:
(i) being vertically freely downwardly movable relative to said bottom portion and having a centrally disposed first guide hole to permit wire withdrawal therethrough;
and
(ii) comprising an inner ring member and an outer frame member radially spaced from one another, said inner ring member and said outer frame member being disposed in the same horizontal plane and being securely connected to one another on the upper side thereof by a plurality of bridge members at spaced positions around said inner ring member and said outer frame member;
and
(f) a resilient member mounted on each of said bridge members, said resilient members:
(i) resiliently contacting the inner periphery of said bottom portion and
(ii) being radially outwardly movable in their entireties relative to said bridge members, whereby the resilient force with which they bear against the inner periphery of said bottom portion can be adjusted.
