Patent CA-2121205-A1 (CA)
Title: Easy-open container end
Inventor: SCHUBERT JAMES R
IPC: B65D17/34
Filed: 1994-04-13
Abstract: Abstract The invention, relating to an easy-open metal container end, places a portion of the metal of the tear panel (12), in the region where a score stop otherwise would be located, under compression by forming a short coined depression or bead (40) in the tear panel, preferably in the public side, close to the score line (15) at least at the end of the vent region (35) opposite from the inner hook (16), which is located at the radially inward end of the tear panel score line.  During initial opening or venting action, as the rivet (25) is lifted by initial tab motion, separation proceeds along the score line, beneath the nose (28) of the tab (27).  The metal adjacent and in this coined depression tends to move partially underneath the metal on the opposite side of the score line from the coined vent bead.  This action provides sufficient disruption or retarding of the score line separation or rupture, during venting, to confine such separation to the vent region until internal pressure is vented.  Further separation of the tear panel can proceed under control of continued raising tab motion and resulting opening force.  By providing such a coined vent bead, the score stop may be made considerable less deep leaving adequate residual metal along score line (15), or the score stop can be entirely eliminated in some cases, thereby making it possible to achieve consistent and proper venting in ends made of thinner metals, e.g. in the order of 0.009--0.008 inch.

Abstract: The  amount  of  nitrogen  oxide  (NOx)  and  hydrocarbon emissions emanating via the exhaust during operation of a gaso-line engine is reduced by dispensing to a gasoline engine adjusted to operate primarily at an air-to-fuel ratio between lambda of about 0.9 to about 1.15, a gasoline that contains a minor amount of (i) a cyclopentadienyl manganese tricarbonyl compound and (ii) an alkyllead antiknock agent.  Components (i) and (ii) are proportioned such that there is dissolved in the fuel a substantially equal weight of manganese as (i) and lead. as (ii), and the amount of (i) and (ii) used in the fuel is an amount that reduces the amount of NOx and hydrocarbons in the engine exhaust on combustion of the fuel with an air-to-fuel ratio between lambda of about 0.9 to about 1.15.  Lambda is the actual air-to-fuel ratio divided by the stoichiometric air-to-fuel ratio.  The stoichiometric air-to-fuel ratio is a lambda value of one.
