Abstract: A method for providing an end-stop for a slider on a resealable thermoplastic bag is provided. The resealable thermoplastic bag includes a profile track having a first side panel and a second side panel. A clip having first and second legs is made to straddle the profile track such that the first leg of the clip being proximate to the first side panel and the second leg of the clip being proximate to the second side panel. One of the legs has an inward-facing protrusion for engaging a corresponding recess on the panel proximate thereto, such that the clip resists vertical motion on the profile track. The other of the legs of the clip is sealed to the panel proximate thereto.

Abstract: A zipper profile for a fastener assembly is provided. The profile includes a male element and a female element. The female element has a pair of jaws that are movable with respect to one another about a common fulcrum region, and a pair of arms each of which are coupled to a corresponding one of the pair of jaws at the fulcrum region. Each of the arms has an end opposite from the fulcrum region that is shaped for engagement with a slider, and the jaws have an open position and a closed position. The arms are disposed to cause movement of the jaws between the closed position and the open position when the arms experience displacement about the fulcrum region. Displacement about the fulcrum region may be effectuated by motion of a slider relative to the arms. The male element is captured by the female element when the jaws are in the closed position and released when the jaws are in the open position.

Abstract: An improved engineering steel conveyor chain capable of supporting a downward load as the chain moves along a horizontal path is disclosed. The conveyor chain includes a plurality of interconnected link assemblies. The link assemblies include spaced parallel metal side bars and a plurality of roller assemblies mounted for rotation between the metal side bars. Each of the roller assemblies include an outer metal roller and an inner plastic bushing. The plastic bushing has a compressive strength between 20,000 and 25,000 psi and includes protuberances at its ends for restricting engagement of the outer metal roller with the side bars. The plastic bushing includes an inner lubricous surface thereby eliminating the need for supplemental lubrication.

Abstract: A trash bag dispensing package including a T-shirt bag having a roll of continuous plastic bags. When the leading bag is being pulled from the roll and out the mouth of the T-shirt bag, the roll rotates within the T-shirt bag in an arrangement which provides controlled dispensing of the trash bags. The T-shirt bag may be conveniently hung by its handles from virtually any type of support.
