摘要:
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.

A vented 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 a transition region, including an invertible fold, located between these two sections. 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 spout includes a thicker wall portion for enabling the closure body to maintain a selected orientation. A plurality of venting ears are used to help provide the venting capability.

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.

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.
摘要:
A container and method for preventing leakage therefrom through isolating deformation in the container caused by external forces. The container comprises a container wall having an opening therein, the opening capable of receiving a closure bushing with a sealing member wedged between the closure bushing and the container wall, and a weakened portion of the container wall not in wedged engagement with the sealing member capable of bending in response to an external force so as not to deform the portion of the container wall in wedged engagement with the sealing member.
