Abstract: A sealing article for use with a fluid conveyance device comprises an elastomeric body including a first end defining a disk-shaped annular protrusion, and an annular recess formed in a sidewall thereof directly adjacent the first end of the body in an axial direction of the body. The recess is sized to receive at least a portion of the annular protrusion in response to the sealing article being inserted into an interior cavity of the fluid conveyance device. A barrier material is attached to or formed on a first end of the body and extends over the radial protrusion.

Abstract: A method for making a stopper. The method includes the step of providing a first tool defining a first tool cavity and a second tool defining a second molding cavity. A first plug member having an upper surface and a lower surface also is provided, the upper surface of the first plug member having a concave portion. The first plug member is faced in the first cavity such that at least a portion of the lower surface of the first plug member is in contact with the first cavity. The second tool defines a hole therethrough such that the hold provides fluid contact between the second tool cavity and a point exterior to the second tool.

Abstract: Applicator assembly comprising a container for liquids having a bottom wall member, a cap member having means for detachably securing it over a discharge opening in the container. An upstanding wall and a bottom wall having an upstanding post member having an opening communicating with the interior of the container define a measuring chamber for a predetermined measured quantity of the liquid with a cylindrical wall portion of the cap member. An elongated tubular member is mounted in the opening in the post member extending downwardly into the container adjacent the lowest portion of the bottom wall member. A valve seat plate member is mounted at the open end of the cylindrical wall portion and has a wall portion terminating in a valve opening which is tapered towards the valve opening and functions as a funnel during discharge of contents to ensure complete transfer from the measuring chamber to a dispensing chamber above the measuring chamber.

Abstract: A method of blanking articles or products molded in a unitary sheet and arranged in a predetermined configuration or array consisting of the steps of configuration or array comprising a plurality of identical symmetrical segments consisting of the steps of first blanking the articles in a first segment of the sheet, rotating the sheet to present the next adjacent segment to the blanking dies, blanking the articles in the next successive segment and repeating the indexing and blanking until all of the articles in all of the segments have been removed from the sheet.
