摘要： An easy-opening container wall having a line of weakness therein defining a panel at least partially removable from the container wall and a tab attached to the panel to initiate severance of the panel from the container wall. The panel is weakened along a plurality of circumferentially extending regions. Preferably, the panel includes first and second axially offset sections interconnected by a connecting wall with one of the weakened regions being formed in each of the sections closely adjacent the connecting wall.

摘要： An easy opening container wall including a container wall having a line of weakness therein defining a tear portion. The container wall has a rupturable region other than the line of weakness. A tab is attached to the container wall and movable to initiate severance of the tear portion. The tab includes a rupturing element which is movable generally toward the rupturable region prior to manipulation of the tab to rupture the rupturable region and form a vent opening in the container wall.

摘要： 1,229,113. Making rivets; extruding; riveting. E. C. FRAZE. 11 Aug., 1969 [21 Nov., 1968], No. 40052/69. Headings B3A, B3P and B3U. [Also in Division B8] One rupturable rivet 117 of a pair of spaced rivets 115, 117, which are integral with a tearout panel of an aluminium can end and secure a pull-tab 113 to the panel, is formed by squeezing the can end panel between upper and lower coining dies 55 and 57 so that the metal flows radially inwards into a recess 67 in the upper die to form a closed hollow unstaked rivet 59 which is joined to the coined region 73 of the can end by a thin, readily rupturable annular region 79. The tab is then placed over the unstaked rivet, the tab being clamped to the can end by coacting members 85, 87, and a punch 89 utilized to complete the formation of the rivet. The lower coacting member is provided with a projection 93 extending into the rivet to prevent thickening of the region 79 during the punching operation. Prior to the nose end of the tab initiating rupture of the score line 109 defining the tear-out panel on lifting the tab, another score line 127, Fig. 1 (not shown), which extends laterally between the rivets 115 and 117, is ruptured on lifting-the tab so as to vent the can interior to atmosphere. In a modification, Fig. 8 (not shown), the rivet 145 is not ruptured in use, and the rupturable transverse vent score line 173 extends radially inwards of the rivet 145.

摘要： Easy opening ends for containers, particularly containers of the full panel pull out variety, include an end wall having a protective guard means which cooperates with the score line. A tab including a nose and lifting end is affixed to the end wall by an integral rivet, the nose of the tab being adjacent to the score line, while the lifting end extends towards the center of the end wall. The end wall includes a stiffening structure located beneath the tab and adjacent to the rivet to prevent upward flexing of that portion of the end wall in the immediate vicinity of the integral rivet, such flexing tending to permit radially inward movement of said tab out of operative rupturing position with respect to the score line. The stiffening structure in the end wall may take various forms each of which operates as a reinforcing component for a localized portion of the end wall. For example, the stiffening structure may include a pair of spaced angularly disposed depressions which extend downwardly or towards the non-public side of the end wall. In another form an arcuate ridge, in the form of a raised portion, includes spaced legs positioned adjacent to the rivet for reinforcing that portion of the end wall underlying the lifting end of the tab. As a variant, the stiffening structure may include a raised bead operative to prevent the lifting end of the tab from being grasped by the user until it has been raised sufficiently to initiate rupture of the score line. Various other forms of stiffening structures are described.

摘要： D R A W I N G
A COINED INDENTATION AT THE BENDING LINE OF AN EASYOPEN CAN END TEAR STRIP. THE INDENTATION HAS NEARLY VERTICAL SIDE WALLS OF INCREASED THICKNESS AND THE METAL BETWEEN THE COINED AREA AND THE TEAR-STRIP SEVERING SCORE IS IN COMPRESSION. THIS PREVENTS THE FORMATION OF CRACKS IN THE SCORE AND INCREASES THE STRENGTH OF THE STRIP TO PREVENT ITS BREAKING WHEN A CREASE IS FORMED WHEN THE CAN IS OPENED IMPROPERLY.
