The disclosure describes embodiments of an apparatus including a first gas chromatograph including a fluid inlet, a fluid outlet, and a first temperature control. A controller is coupled to the first temperature control and includes logic to apply a first temperature profile to the first temperature control to heat, cool, or both heat and cool the first gas chromatograph. Other embodiments are disclosed and claimed.

A can lid is provided to be made of a steel plate and easy to be opened. An opening piece is enclosed by a score line formed on a periphery of a panel portion. An installation portion of a tab is attached to the opening piece at a site close to a circumference of the opening piece. The tab includes a finger grip portion that is situated closer to a center of the opening piece than the installation portion, and a nose portion that is situated on an opposite side to the finger grip portion at a radially outer side of the score line. A portion of the panel portion underneath the nose portion serves as a support section that supports the nose portion from below. An outer circumferential bead is formed on a radially outer side of the score line to enhance a bending stiffness of the support section.

A can end including a central panel with an expandable bubble disposed thereon is provided. The use of an expandable bubble allows for an expandable rivet button and thereafter an expandable rivet that has an enhanced overlap of a tab body. Such an expandable rivet allows for the use of a metal sheet with a thinner base thickness.

A food or beverage container having a body portion or an end portion that includes a metal substrate with a coating composition disposed thereon. The coating composition includes a water-dispersible acrylic linear block copolymer made by surfactant-free heterogeneous radical polymerization (“SFHRP”). The block copolymer imparts a desirable combination of flexibility and corrosion resistance to the coating composition, and the substantial absence of surfactants during polymerization contributes to other desirable properties including good blush resistance.

The disclosure describes embodiments of an apparatus including a first gas chromatograph including a fluid inlet, a fluid outlet, and a first temperature control. A controller is coupled to the first temperature control and includes logic to apply a first temperature profile to the first temperature control to heat, cool, or both heat and cool the first gas chromatograph. Other embodiments are disclosed and claimed.

A can lid comprising: a main body comprising a laminate metal sheet, the laminate metal sheet comprising a metal sheet and a first resin film on a major surface of the metal sheet, the major surface having a score line delimiting an opening piece, the first resin film comprising a first resin layer comprising a dimer acid-copolymerized polyester resin and being amorphous; and a tab attached to the main body and adapted to cause a cleavage along the score line.

A tab formed of a metal plate in which a resin film is laminated on at least one main surface of a base member made of a metal material, includes: a fixing portion including a rivet hole into which a rivet formed on a panel portion of a can lid is inserted; a pressing portion formed integrally with the fixing portion and configured to press a portion in a region defined by a score line formed on the panel portion; and a finger hook portion formed integrally with the pressing portion.

A can end including a central panel with an expandable bubble disposed thereon is provided. The use of an expandable bubble allows for an expandable rivet button and thereafter an expandable rivet that has an enhanced overlap of a tab body. Such an expandable rivet allows for the use of a metal sheet with a thinner base thickness.

A can end including a center panel, an annular portion disposed about the center panel, a standard chuck wall disposed about the annular portion, and a curl extending radially outwardly from the standard chuck wall. The annular portion includes an enhanced annular countersink.

An improved and safer opening mechanism for a pressurized container is provided that includes a synchronous relationship between a safety cap and a sealable plate, such that the safety cap covers the sealable plate when it is removed from the container.
