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.

In an easy open can lid a pulling-up direction of a tab acts toward a center of the lid while securing a finger hooking property with respect to the tab, by devising a shape of an embossed portion. In a can lid in which a tab for score breaking is fixed to a main body, and an embossed portion, into which a fingertip is insertable, is provided in the vicinity of a rear end of a finger hook portion of the tab, the embossed portion has a slope formed at a rear end side of the finger hook portion, and the slope of the embossed portion is provided with a guide recess for guiding a fingertip that extends toward the center of the lid at least up to a position thereof facing a central portion in a width direction of a back surface of the finger hook portion.

A method of forming a can end shell is provided which includes providing a can end shell having a central panel portion, a first panel radius around the central panel portion, a chamfer extending from the first panel radius, and a second panel radius around the chamfer, coining the can end shell to form a coined section in the first panel radius around at least a portion of the circumference of the central panel portion, and reforming the can end shell to form a step in the chamfer.

There is shown in embodiments of a closure mechanism configured to fit over the top of the can and prevent access. The closure mechanism is a child resistant senior friendly mechanism that can be opened and removed by the senior when access to the can is desired. The closure mechanism is designed for a single use as once removed it will no longer prevent access of the top of the can.

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 reclosable metal lid of a beverage can comprising a centre panel in which scorelines are made, allowing to tear out an aperture, a circumferential panel connecting the centre panel with the neck of the can, and a pull-tab attached by a rivet, and a collar for connecting the lid with the can body, equipped with a closing rotatable panel rotating around the rivet axis is, wherein the centre panel (4) is above the circumferential panel (3) and has in the connection spot with the circumferential panel (3) an additional embossing forming a guide-rail, and the rotatable panel (5) is mounted on the lid on this guide-rail, while the pull tab (7) is affixed to the rotatable panel (5) by the rivet (6), wherein the size of the rotatable panel (5) corresponds to the size of the centre panel (4), and the rotatable panel (5) comprises an aperture which corresponds to a drinking opening of the lid.

The invention relates generally to containers, particularly to cans (14), for example, for beverages, to a container opening device (9), a container (14), a closure arrangement (12) for a container (14), and a blank for a container opening device (9). The container (14) is typically sealable and has closure (16) attachable thereto to seal the container (14), wherein the closure (16) has a peripherally weakened zone (20), or a partly peripherally weakened zone (20). The container opening device (9) comprises an actuator tab (22) operatively attachable to the closure (16) adjacent the zone (20) such that actuation of the actuator tab (22) between first and second positions causes shearing or detachment of the zone (20) from its weakened periphery thereby to provide an opening to an interior of the container (14), in use; and a pull member (10) attached or attachable to the actuator tab (22) to facilitate actuation of the tab (22) between the first and second positions. It will be understood that the container (14) and closure arrangement (12) comprise the device.

The present invention provides a closure for a container having a generally planar top adapted to enclose the opening of a container, a sealable opening, a closure adapted to seal the opening and hingedly movable between a first sealed position and a second opened position, a generally planar tab having a first end pivotably connected to the planar top and axially rotatable between a first position where the planar tab is aligned to generally occlude the sealable opening and a generally opposed second position, such that the planar tab is secured in the first position and the planar tab can be axially rotatable between the first position and the second position upon application of an axial rotational force to the second end of the planar tab.

A reclosable can end is provided. In some embodiments, the reclosable can end comprises: a lid base that comprises a scored area; a tab that causes the scored area to at least partially separate from the lid base to expose an opening in the lid base; a closure flap, wherein the closure flap comprises: a first portion; a second portion; an opening; and a protruding portion; and a rivet that connects the tab and the closure flap to the lid base such that the tab and the closure flap are configured to rotate around the rivet, wherein the first portion of the closure flap is configured to be inserted into the opening in the lid base end when the tab and the closure flap are rotated to a position corresponding to a position of the opening in the lid base.

A container can end includes a concave dome shape and may forgo a peripheral reinforcing bead around the center panel. The tab may also be curved. Tooling for forming the end and a corresponding method are provided.
