Abstract: A container comprising a wall structure defining an opening and an outwardly projecting bead extending peripherally about the opening is disclosed. A plurality of outwardly projecting vent ribs are provided on the bead. A closure which includes a cover member having a downwardly extending skirt is provided for sealing the container. The downwardly extending skirt has an inner peripheral surface which includes a curved member, for contacting the bead and the plurality of vent ribs, and also a tapered member extending downwardly from the curved member. Upon attachment of the cap to the container, the plurality of vent ribs allow for pressure to be released from the container over the bead and about the plurality of vent ribs, while allowing a sealing engagement of the cap with the closure to resume after relief of the pressure from the container.

Abstract: A yarn carrier having an improved surface for having a yarn package wound thereon. The improved surface for the yarn carrier is provided by a plurality of separate, interrelated projections that combine to receive a proper yarn package without entrapment of yarn between projections and while avoiding sloughing of yarn from the carrier.

Abstract: An improved textile spindle and yarn support tube construction for use in textile winding machines, in particular, those having a reciprocating rail, ring and traveler type winding mechanism. The spindle comprises a base portion having a conventional whorl and mounting pin, and an upper, yarn tube-receiving shaft portion of generally circular cross-sectional configuration. The upper portion of the spindle shaft is provided with radially outwardly biased elements which engage the internal passageway of the yarn tube when seated thereon to provide driving connection of the tube to the spindle. The yarn supporting tube is of elongate shape having an internal longitudinal passageway therethrough.

Abstract: An improved textile carrier is described and disclosed herein for improved spinning stability at high speeds and includes a molded plastic barrel having an outside taper inwardly from a large bottom end to a smaller upper end, with the outside surface of the barrel preferably having a texture to properly receive yarn therearound. The inside diameter of the barrel varies from bottom to top and has a section located intermediate the length of the barrel to properly receive and position a driven spindle therein and to provide stability along the length of the barrel at high spinning speeds. An approximately constant clearance is provided between the spindle and the barrel substantially along the length of the intermediate section. In a preferred arrangement, the intermediate section is made up of a plurality of ribs of unitary construction with the inside wall of the barrel, being equally spaced therearound.
