摘要:
A method of making a can end, which includes a recessed panel defined by an upwardly extending chuck wall, a peripheral scoreline disposed in a public side of the panel proximate to the base of the chuck wall, a tab fastened to the panel by a rivet, includes the step of employing tooling to form a pressure resistance bead extends around the panel inboard of the peripheral scoreline and outboard of the rivet. The tooling forms a saw tooth panel formation proximate to the pressure resistance bead inboard of the pressure resistance bead. Among other benefits, the pressure resistance bead and saw tooth panel formation created by the tooling and method combine to resist wrinkling or other undesired deformation of the can end.
摘要:
A can end that is attached to a metal can body with a bottom end forming a cavity that may be filled with food, liquid, etc. The can end is made of metal with a bead configuration located in the outer circumference of the can end that increases its resistance to deformation when subjected to high pressure cooking environments and assists in preventing the can end from separating along the frangible score.

The invention covers a number of alternative improvements to the prior art pull tab opener used to open container such as soda cans. One improvement is by forming the nose of the pull tab at a certain angle to the body of the tab or to the lifter tip or the nose tip, thus allowing the user to tilt the tab thus lifting the pull tip higher and providing more room for the user to insert the finger tip under the pull tip thus making it easier to open the container. Another improvement is by providing a deeper finger well under the lifter tip, again providing more room to insert the finger tip and making it easier to open the container.

Provided is a resealable easy-open end including a panel functioning as an end for hermetically sealing a can and having an opening formed at one side thereof and on which a score (S) is engraved; a tab having a first button hole formed in a button coupling part formed at a center thereof, rotatably coupled to a first button protruding from the panel through the first button hole, and rotatably installed between a first position at which a front end pressing part is disposed on the opening and a second position at which a rear end finger portion is disposed on the opening; and a closing plate rotatably installed between the first position and the second position, and to configured to be supported by the tab at the second position to close the opening when the tab breaks the score to open the opening.
摘要:
A can end having a countersink bead, an inclined chuck wall and a strong seam, resists distortion from its circular profile when subjected to thermal processing or when packaging carbonated beverages. This high hoop strength affects the manner in which the can end ultimately fails when placed under extreme abuse conditions, even if buckle pressure performance is within industry specified standards. The can end of the invention has control features introduced which control the failure mode whilst maintaining specified buckle pressure performance. In one embodiment, the can end has a two part wall and a control feature that comprises expansion of the countersink bead to act as a trigger for local peaking, together with a groove in the chuck wall which prevents the peaking force from being concentrated at a single point which could result in leaking by the production of a pin hole.

A beverage can end is described. The beverage can end has a curl defining a perimeter of the can end, a chuckwall extending downwardly and radially inwardly from the curl, and a transition wall joining the chuckwall to an outer peripheral edge of a center panel. The transition wall is formed in compression such that a portion of the transition wall exhibits a compressed segment having a thickness which is 1% to 20% thicker than a thickness of the center panel.
摘要:
The invention relates to a can, comprising a body provided with a panel and a tab connected to the panel, which tab has a front tab part and a rear tab part for gripping and tilting and forming with the tab front part an opening in the panel along a panel score line, wherein the tab is in a tilted position due to a deformation of a tab-panel connection, to a panel and to a method of making the panel and/or can.
