Abstract: A container includes a casing defining an annular chamber for a volume of thread or wire pre-wound into coils to accommodate therein without becoming tangled, and a cover detachably closed onto the casing. A clearance exists between an upper peripheral edge of the casing and a lower peripheral edge of the cover when the cover and the casing are closed, allowing a free end of the thread or wire in the annular chamber to locate outside the container via the clearance. Therefore, the thread or wire in the container could be easily accessed and pulled outward at the free end for use without the need of opening the cover. The container could be refilled with a new thread or wire and therefore could be repeatedly used.

Abstract: A positioning structure enabling blister-on-card packages to stand vertically in a packing box to facilitate display of commodities in the packages is provided. The positioning structure includes a pair of positioning plates symmetrically attached to two opposite inner wall surfaces of the packing box. Each of the positioning plates is provided at one side with two horizontal rows of equally spaced projections, such that a vertical straight insertion space is formed between any two adjacent pairs of projections in the two rows. Blister-on-card packages are positioned in the packing box with two lateral edges of the cards forming a back of the packages received in two insertion spaces symmetrically provided on the two positioning plates, allowing the blister-on-card packages to stably and upright stand in the packing box for display.
