Abstract: An improved child-resistant self-opening end closure of the type wherein the tab is nested between end panel protrusions which obstruct access to the tab ring and prevent grasping and lifting of the tab to open the container. The end panel is formed with a recess beneath the nose portion of the tab which provides maximum clearance between the tab and the end panel, whereby depressing the nose portion of the tab causes the ring portion to tilt upwardly sufficiently to permit it to be grasped.

Abstract: An improved pull tab mounting arrangement for an easy open end closure member, characterized by the provision of improved pull tab positioning means for maintaining the pull tab in a desired orientation relative to the panel-defining score line and minimizing tab protrusion from the end closure member. A depression is formed in the end panel and a pierced hole forming a protrusion with a jagged edge is incorporated in the tab nose portion above the depression, between the free extremity of the tab and the rivet means that secures the tab to the end panel member. The jagged protruding edge of the protrusion is driven into the base portion of the depression during the staking operation, thereby providing an anti-rotation interlock between the tab and the end panel. The depression serves as a detent positively restraining rotation of the tab and displacement of the nose relative to the score line.

Abstract: An air lead-in for a can body former of the type comprising a ram having a can-forming punch at its end which draws and wall-irons a metal blank by forcing it through a series of rings, the ram and punch having air passages therein through which compressed air is pulsed in a programmed series to faciliate stripping a formed can from the punch. The lead-in comprises novel linkage having articulatingly connected oscillating sections with interconnected air passages therein one end of the linkage having a pivot connection to the ram passages at one end and the other end having a connection to a rocker drive arm air passages from a source external of the arm.

Abstract: An improved easy-open end closure has a generally C-shaped ancillary scoreline in the end panel closely adjacent a rivet which is positioned between a piercing portion of a tab to which it is attached and at least a portion of the rupturable ancillary scoreline. The peculiar shape of the scoreline, with its inwardly looped ends, facilitates movement of the handle portion of the tab away from the end panel by rendering the adjacent portion of the end panel more flexible and minimizes tear out of the flexing portion of the panel by substantially eliminating areas of stress concentration.

Abstract: A container end panel having a non-detachable flap portion partially severable from the panel to provide an opening. The flap portion is recessed below the remainder of the panel and is broken away by a fitment which fits into the recess. The fitment is adapted to be pushed inwardly and after rupturing the score between the panel and the flap functions to swing the flap inwardly about a hinge formed by the unscored metal connecting the flap to the panel. The fitment is pressed into the opening and snaps within the opening and provides a guard shielding the users finger from the raw edges at the tear edge about the opening. The invention is also directed to a formation of the inner edge of the ring to facilitate rupturing the score and thereafter swinging the panel inwardly.

Abstract: A mounting for a long horizontally disposed reciprocal ram of a can forming machine. The ram which carries a punch or mandrel at one end and is connected to a reciprocating drive at its other end is supported intermediate its ends from the machine framework by a plate which slides in a guideway. The plate, which extends parallel to the ram longitudinally thereof has a fixed connection at one end with the ram which is suspended beneath the plate. The plate which runs on guideways becomes very hot and is free to expand longitudinally independently of the ram since it has creep-accommodating connections through high thermal resistors with the ram at longitudinally spaced points which freely permit such expansion and resist transmission of heat into the ram.

Abstract: A mobile applicator for roofing tar having advance spray nozzles followed by spreader brushes carried on a wheeled motorized chassis which also supports a tar hopper which is maintained in heated condition and agitated by the exhaust of an internal combustion engine which drives the apparatus, the engine exhaust being selectively ported to heat the hopper or to by pass the same when the liquid tar becomes sufficiently hot to prevent overheating and also to maintain the lines from the hopper to the spray hot to prevent solidification of the sealant, viz., the tar.

Abstract: An improved pull tab mounting arrangement for an easy open end closure member, characterized by the provision of improved pull tab positioning means for maintaining the pull tab in a desired orientation relative to the flap-defining score line. Two protrusions formed in the closure end panel prevent rotational displacement of the tab about the attachment rivet resulting from contact with the knock out pad during the filling and seaming operations or from improper handling subsequent to filling. The protrusions, which are symetrically disposed with relation to an end panel chord drawn along the axis of the flap, serve as anti-rotation abutments and may further serve as spacing means to prevent contact between the tab and the knockout pad. The protrusions may be disposed abutting the tab legs, interior and tangent to the circle of the interior of the tab ring or beneath the ring itself.

Abstract: An improved easy-open end closure which maintains close contact between a tab and container end panel prior to opening, regardless of doming of the end panel. An integral rivet is formed on the end panel inclined off-center 10.degree.-20.degree. toward the end panel center, the rivet securing the pull tab thereto whereby the tab converges with the end panel toward the periphery thereof.SUMMARY OF THE INVENTIONWhen easy-open containers employing integral off-center rivets are subjected to excessive internal pressure the end closure bulges outwardly and exerts an upward force on the tab. Occassionally the tab is rotated upwardly about the rivet and retains this displacement after the internal pressure has been reduced and the end panel bulging has subsided. Tab displacement of this sort detracts from the appearance of the container.

Abstract: A container end panel having a non-detachable flap portion partially severable from the panel to provide an opening. The flap portion is recessed below the remainder of the panel and is broken away by a fitment which fits into the recess. The fitment is adapted to be pushed inwardly and after rupturing the score between the panel and the flap functions to swing the flap inwardly about a hinge formed by the unscored metal connecting the flap to the panel. The fitment is pressed into the opening and snaps within the opening and provides a guard shielding the users finger from the raw edges at the tear edge about the opening. The invention is also directed to a formation of the inner edge of the ring to facilitate rupturing the score and thereafter swinging the panel inwardly.

Abstract: An improved pressure welding technique permits high speed room temperature seam bonding of metal sheets. A metal interlay is placed between the faying surfaces to be bonded and the assembly is compressed until the interlay is properly spread over the faying surfaces. The interlay has a cross-section designed to produce a highly differential flow when subjected to external compressive loads. This differential flow causes shear movement between the interlay and the faying surfaces which effects the weld. Joining speeds in excess of 10 feet per second are possible, with a reduction in sheet thickness of about 5 percent.

Abstract: An improved non-detachable end closure has an outwardly facing dome-shaped opening flap. Non-detachable end closures, wherein the rivet for tab attachment is located in the center of the opening flap, may evidence low panel distortion under internal pressure. Forming the opening flap as an outwardly-facing dome provides increased distortion resistance and making the tab ring-shaped permits nesting of the ring in shielded location to prevent accidental opening. The arrangement of a dome within a well, which nests the ring tab, permits locating an expandable securing lug for the tab to the non-detachable dome panel within an upwardly widening space between the dome and interior of the ring tab. The structure makes the ring tab relatively inaccessible and inhibits the tendency of users who are familiar with current detachable ring pull tabs from pulling the tab off and encourages the user to push the tab inwardly.

Abstract: A fishing reel comprising a motorized spinner for taking up the line and having a switch positioned for easy thumb control. The reel is driven by a gear train and is adapted to be driven simultaneously by the motor and by manual cranking or the motor alone or manually. The reel comprises a housing and incorporates an electric motor mounting which is yieldable to accommodate lateral deflection of the motor to wedge apart gears on the motor drive shaft and a spinner drive shaft upon an overload developing thus preventing destruction of the motor.

Abstract: A standard easy-open closure is converted to a child-resistant safety closure by the addition of an insert which is mounted on the rivet between the end panel and the tab. The insert extends beneath the piercing member and prevents cracking of the end panel score. The tab must be depressed, thereby allowing the insert to be rotated from beneath the piercing member, before the closure may be removed. These two additional operations, which must be performed in proper sequence, render removal of the closure beyond the capability of the young child.
