Abstract: A suture anchor includes an outer sleeve having a longitudinal throughbore and defining leading and trailing ends and an insert positionable within the longitudinal throughbore of the outer sleeve. The insert defines at least one suture track for slidably supporting a suture whereby opposed free ends of the suture extend from the at least one suture track through the longitudinal throughbore to extend beyond the trailing end of the outer sleeve to be tensioned and secured relative to the tissue. The outer sleeve may include an external thread for threaded rotation and advancement into the tissue.

Abstract: One or more lamp bulbs are protectively packaged by inserting them into an open-ended wrapper of single-faced corrugated paperboard and slip-fitting the resulting lamp pack into an open-ended boxboard sleeve that overlies and closes the open ends of the wrapper. The sleeve has oppositely disposed corner portions with inwardly bowed flexible junctures of such curvature that they exert a wedging force on the associated end edges of the inserted wrapper. The resulting clamping action frictionally locks the wrapper and the contained lamp bulbs within the boxboard sleeve despite the smooth surfaces of the latter.

Abstract: The ability of an open-ended corrugated-paperboard lamp wrapper to withstand compressive forces and retain an inserted frictionally-gripped lamp are both enhanced by orienting the corrugations so that they extend obliquely across the walls of the wrapper at an angle of from about 10.degree. to 35.degree. with respect to the transverse axis of the wrapper. The compressive strength of a single-lamp wrapper fabricated from single-face corrugated paperboard having corrugations offset by 20.degree. is increased by 19% and lamp-retention is increased by 20% compared to a conventional wrapper having corrugations that extend parallel to the transverse axis.

Abstract: A fluorescent lamp or similary shaped fragile article is frictionally locked with a protective open-ended wrapper of tubular sleeve-like configuration by an inturned tab that constitutes a hinged part of the wrapper and is sandwiched between the inserted lamp and the wrapper wall. The wrapper is preferably fabricated from single-face corrugated paper and the tab is swingable about a hinge line such that the corrugations of the inturned tab extend transversely with respect to and thus do not nest with the corrugations of the wrapper, thereby enhancing the effectiveness of the tab as an integral article-retaining means.

Abstract: A single lamp bulb is retained within a collapsible open-ended tubular sleeve of stiff paperboard by an integral panel that extends within the interior of the sleeve and has a medial cut-out which interlockingly accommodates a protruding arcuate portion of the lamp bulb. The locking panel is slit, scored and secured to only one of the sleeve walls in such a manner that it automatically flexes and is pushed into locking position when the sleeve is set up for use. The central portion of the panel obliquely spans a corner of the erected sleeve and another portion of the panel frictionally engages and is wedged against one of the sleeve walls to provide a bracing action that inhibits the inherent tendency of the sleeve to return to collapsed condition.
