Closure Systems International Inc.

A polymeric closure includes a first closure portion including a top wall portion and an annular skirt portion. The top wall portion includes polymeric plug seals extending downwardly therefrom. The polymeric plug seals extend around a circumference of the closure with a respective space located between each of the adjacent plug seals. The skirt portion depends from the top wall portion. The annular skirt portion has an interior surface. The interior surface of the skirt portion includes an internal thread formation. The plug seals are spaced from the interior surface of the skirt portion and assist in sealing with a container. The plug seals provide a seal with a finish of the container across at least 40 to about 90 percent of the finish.

A one-piece closure includes first and second closure portions. The first closure portion includes a first polymeric top wall portion and a first polymeric annular skirt portion depending from the first polymeric top wall portion. The first polymeric top wall portion includes a continuous wedge seal extending from an inner surface of the first polymeric top wall portion. The continuous wedge seal includes a surface-tension geometric structure being located therein to assist in preventing or inhibiting contents of a container from leaving the one-piece closure when the first closure portion is in an open position. The second closure portion includes a second polymeric top wall portion and a second polymeric annular skirt portion depending from the second polymeric top wall portion. The one-piece closure is adapted to be opened by flipping the first closure portion with respect to the second closure portion via a hinge or pivot point.

A polymeric closure assembly includes inner and outer shells, and a liner. The inner shell includes a top wall portion and a skirt portion. The top wall portion of the inner shell forms an opening therein. The skirt portion of the inner shell includes a thread formation. The outer shell includes a top wall portion and a skirt portion. The top wall portion of the outer shell forms an opening therein. The liner attaches to an interior surface of the top wall portion of the inner shell and a finish of the container. The liner includes a substrate layer, a separable layer, a foil layer, and an adhesive layer. The separable layer assists in separating the liner into two pieces.

A flip-top closure includes first and second closure portions. The first closure portion includes a top wall portion with a tamper-evident winged section and a middle section, which are connected via a frangible connection. The winged section forms an undercut. The top wall portion includes a drivable structure to assist in threading the flip-top closure into a container. The second closure portion includes an annular skirt portion and a ledge. The annular skirt portion forms an external thread formation. The ledge includes at least one locking protrusion. A hinge connects the first and second closure portions. In an initially closed position, the undercut of the winged section corresponds with and lockingly engages with the locking protrusion. During movement of the hinge from the initially closed position to an open position, the frangible connection breaks leaving the winged section being lockingly engaged with the locking protrusion.

A container includes a sidewall, a bottom and a rim portion, which are integrally formed or connected with each other. The rim portion includes an inner wall and an outer wall. The inner and outer walls are spaced from each other and connected to each other by an extension. An interior opening is defined by the inner wall of the rim portion, the sidewall and the bottom. An exterior opening is formed between the inner and outer walls and the extension. The exterior opening is sized and configured to receive a sidewall of a lid when the container is used with the lid to form a package. The outer wall has a tamper-evident foldable section with first and second ends. The first end is configured to fold back toward and secure to a second end so as to expose the sidewall of the lid.

A closure includes first and second closure portions. The first closure portion includes a top wall portion and an annular skirt portion. The skirt portion includes an internal thread formation. The second closure portion includes a tamper-evident band depending from and being at least partially detachably connected to the skirt portion by a frangible connection. The polymeric tamper-evident band includes a first portion and a second portion connected via a bending area. The first portion has a flared end in which the thickness of the flared end is at least 1.25 times greater than the thickness of a directly adjacent section of the first portion. The second portion has a tab portion and an extension portion.

A closure includes first and second closure portions. The first closure portion includes a top wall portion and an annular skirt portion. The annular skirt portion depends from the top wall portion. The skirt portion includes an internal thread formation for mating engagement with an external thread formation of a container. The thread formation is a helical formation with alternating bumps and valleys. Each of the bumps has a greater width than the valleys. The width of the bumps and the valleys are measured in a direction perpendicular to the top wall portion. The second closure portion includes a tamper-evident band depending from and being partially detachably connected to the skirt portion by a frangible connection.
