Abstract
A bundle of welding electrodes or rods are confined within a substantially rigid cylindrical tube of extruded plastics material, and each end portion of the tube receives a cylindrical cup-shaped body of an end closure member molded of a more resilient plastics material. The body of each closure member is slightly larger than the inner diameter of the tube and is press-fitted into the tube to form an air-resistant seal with the tube. Either closure member may be removed by pulling the body from the tube or by impacting the body with the welding rods within the tube, and each closure member is reusable and resealable with the tube.
Claims19
A welding rod package for use in shipping and storing welding rods in a protected environment, comprising a bundle of welding rods having a predetermined length, an elongated tube of extruded air-impervious plastics material, said tube having opposite end portions and surrounding said bundle of rods, said tube extending the length of said rods and having substantial rigidity for protecting said rods against an impact, a set of end closure members of molded air-impervious plastics material and engaging said opposite end portions of said tube in press-fit relation, each of said end closure members conforming to the corresponding said end portion of said tube and forming an air-resistant friction seal with said end portion, and at least one of said closure members being removable from the corresponding said end portion of said tube and resealable therewith to form an economical and reusable air-resistant enclosure for the welding rods.
A welding rod package for use in shipping and storing welding rods in a protected environment, comprising a bundle of welding rods having a predetermined length, an elongated cylindrical tube of extruded plastics material and surrounding said bundle of rods, said tube extending the length of said rods and having substantial rigidity for protecting said rods against an impact, said tube being air impervious and having opposite end portions, a set of end closure members of molded air-impervious plastics material and including cup-shaped cylindrical bodies extending into said opposite end portions of said tube in press-fit relation, said body of each of said end closure members conforming to the corresponding said end portion of said tube and forming a fluid-resistant friction seal with said end portion, at least one of said closure members being removable from the corresponding said end portion of said tube in response to an impact of said rods within said tube, and said one end closure member being resealable with the corresponding said end portion of said tube to form an economical and reusable fluid-resistant enclosure for the welding rods.
A method of packaging a plurality of welding rods for shipping and storing the rods in a protected environment, comprising the steps of extruding an elongated substantially rigid tube of air-impervious plastics material, cutting the tube to a length generally the same as the rods, inserting the rods into the tube, molding a set of end closure members of air-impervious plastics material, pressing the end closure members into friction engagement with opposite end portions of the tube, forming an air-resistant seal between each closure member and the corresponding end portion of the tube, and forming at least one of the end closure members to be removable from the corresponding end portion of the tube and resealable therewith in response to pressing the closure member onto and from the tube to provide an economical and reusable air-resistant enclosure for the welding rods.
