Abstract: A plastic reel or spool for fine magnet wire or the like is formed of two molded plastic pieces, preferably identical. Each piece preferably has a flange and a section of the core. The core sections have internal transverse lips which abut when the two pieces are assembled. The flanges have openings which permit the introduction of an appropriately dimensioned ultrasonic welding tool head to weld the abutting lip surfaces together.

Abstract: In the rack mounting and display of chilled beverage containers, for ready access and withdrawals by retial customers, the gravity-feed forwardly-inclined shelving having multiple parallel lanes for upright presentation of the containers is formed by combinations of laterally-interlocked identical molded-plastic modules. Each elongated narrow module is of a high-strength ribbed construction and exhibits an upstanding narrow guide wall fully along one edge; when several such modules are joined side-by-side, via separable fastening provisions such as those composed of integral pegs depending from along one edge and accommodating recesses disposed in a narrow ledge along the other, the single guide walls cooperate to define the individual lanes or paths along which the containers must slide from back to front.
