Abstract: A closure for a container opening according to one embodiment comprises a plug including a series of projections and being constructed and arranged to be received within the container opening and an overcap constructed and arranged for being attached to the plug so as to close off an interior of the plug and create an assembly. The projections being constructed and arranged for interfit with a specialized wrench socket for threadedly advancing the plug into the container opening.

Abstract: A unitary capseal for a closure that is installed in a container includes an annular sidewall, a generally circular top panel joined to the sidewall, a snap-on annular rim formed adjacent a lower edge of the sidewall, and an annular sealing lip formed adjacent the annular rim. The cooperating closure includes a serrated flange, a closing plug for threaded receipt by the flange, and a sealing gasket positioned therewith. The container end is formed around the flange interlocking with the flange serrations and creating an outer annular channel that receives the annular rim for a snap-on assembly of the capseal to the container end that in turn positions the capseal over and around the closure. The sealing lip extends radially outwardly from the sidewall and includes a concave surface facing the container end for sealing off the interior portions of the closure from collecting debris.

Abstract: A closure assembly for a container including an internally-threaded annular flange, an externally-threaded closure plug that is received by the annular flange, and an annular gasket positioned between the annular flange and the closure plug for establishing a sealed interface. The container includes a container end panel that is formed over and around a portion of the annular flange and provides an inner axial wall that is positioned between the annular flange and the annular gasket. The clearance between the closing plug and the inner axial wall relative to the size of the annular gasket determines the degree of radial compression of the annular gasket as the plug is threaded into the flange. A radial lip of the plug is designed to contact an upper surface of the container end panel that is formed over the flange as a visual indication when the required tightening torque of the plug within the flange has been reached.

Abstract: A closing ring for a container and lid combination for securing the lid to the container includes a ring body having first and second free ends to be drawn together in order to secure the lid to the container. A link clevis and a lever clevis are welded to the free ends. A link is pivotally connected to the link clevis. A lever is pivotally connected to the lever clevis. The link is connected to the lever at a third pivot connection that travels in a lever slot. The linkage arrangement is completed by the addition of a pair of closing links that are pivotally connected together and connected to the lever at the lever clevis location and to the lever at the third pivot connection.

Abstract: A closure for a container opening according to one embodiment of the present invention comprises a plug including concave recesses and being constructed and arranged to be received within the container opening and an overcap including inwardly projecting convex forms constructed and arranged for interfit into the recesses of the plug, the overcap being attached to the plug so as to create an assembly, wherein the overcap to plug interfit helps to prevent rotation of the overcap relative to the plug.

Abstract: A unitary threaded closing cap for a closure includes a body having a sidewall and a top panel and at least one bail handle unitarily joined to the top panel wherein the at least one bail handle is arranged in three sections, including an intermediate section and opposing end sections, the intermediate section including a shaped portion that extends above the top panel.

Abstract: A container assembly for transporting and storing flowable materials according to one embodiment of the present invention comprises a drum including a lip edge defining a top opening, a lid constructed and arranged to fit over and close the top opening, a closing ring constructed and arranged for securing the lid to the lip edge, and an elastomeric gasket positioned between the lip edge and the lid, the lip edge being constructed and arranged for the formed sidewall, shaped to define a hollow interior, said sidewall including an outwardly facing, concave section.

Abstract: Insertion die tooling for the installation of a flange into a drum end embossment according to one embodiment of the present invention comprises a stationary work station constructed and arranged to receive an internally-threaded metal flange and a portion of a metal drum end, the metal drum end being formed with an embossment to be positioned over the metal flange and a movable pressure unit including a closing collet constructed and arranged with a plurality of collet segments, a punch holder attached to a closing ring, and a pilot that is constructed and arranged to be movable with movement of the punch holder, the pilot including a frustoconical portion constructed and arranged for engagement with the embossment for forming a tapered inner drum end wall adjacent an inner surface of the flange.

Abstract: A closure assembly for a container, the container including a raised outlet defining a dispensing opening, includes a closure body having a nestable and extendable spout formed with a generally cylindrical section, a frustoconical section, and an invertible fold between these two sections so as to enable the closure body to be either nested or extended. The generally cylindrical section defines an outlet opening and a threaded closing cap is assembled to the generally cylindrical section for closing off the outlet opening. A retainer is used for connecting the closure body to the raised outlet wall and the frustoconical section includes a thicker wall portion, described as a memory band portion, for enabling the closure body to maintain a selected orientation upon deflection into the selected orientation in order to provide directional discharge of the container contents.

Abstract: A closure assembly for a container, the container including a raised outlet wall defining a dispensing opening, the closure assembly including a closure body having a nestable and extendable spout with the spout defining an outlet opening, a tamper-evident closing cap for assembly to the spout for closing off the outlet opening, the closing cap including a pair of movable bail handles for pulling upwardly on the closure body, each bail handle including a deployable arcuate flap portion constructed and arranged to be deflected into an inserted orientation prior to initial opening of the closure assembly and to be deployed so as to be visible in response to lifting movement on the bail handles and a retainer for attaching the closure body to the raised outlet wall.
