Definitions

  • a primary object of this invention is to provide a novel peripheral weakening line and there being attached to the removable panel portion a pull tab which is of a constrip portion.
  • Another object of this invention is to provide a novel container end which includes a removable panel portion defined by a peripheral score line, Iand there being attached to the removable panel portion a pull tab for facilitating the removal thereof, the pull tab being hingedly connected to the removable panel portion and having a stiifened nose which is engageable with the removable panel portion immediately adjacent the score line so as to apply a localized pressure on the removable panel portion and thereby effect the initial rupture of the container end,
  • Yet another object of this inventlon is to provide a novel pull tab which is intended to exert a panel rupturing pressure with a nose thereof, the pull tab being provided with a peripheral rib which terminates at the nose in two terminal ends which are transversely spaced and which define the stiened nose.
  • a further object of this invention is to provide a novel pull tab
  • a still further object of this invention is to provide a novel but simple one-piece pull tab which is readily formed from sheet metal and which is reinforced to have Sufficient stiffness where required, the pull tab including a pull ring which is reinforced by the reverse folding of the inner and outer peripheral edges thereof, the pull ring being connected to a tab body by means of a weakened in two transversely spaced terminal ends which dene a stiffened nose on the tab body, and the tab body further having a C-shaped cut therein opening towards the nose and defining a mounting ear which is hingedly connected to the tab body along a transverse hinge line disposed intermediate the mounting ear and the nose.
  • FIGURE 1 is a fragmentary top perspective view of an easy opening container formed in accordance with this invention.
  • FIGURE 3 is an enlarged fragmentary vertical sectional view taken Ialong the line 3-3 of FIGURE 2 and shows FIGURE 5 is an enlarged fragmentary vertical secposed in recessed relation with respect to the double seam 13, as is clearly shown in FIGURE 3.
  • the end panel 14 is provided Iwith a peripheral weakening line in the form yscore 15 which is continuous and It is a primary purpose of this invention to provide means for removing the panel portion 16 by means of including welding, could be utilized.
  • the pull tab 17 includes a tab body which is generally referred to by the numeral 19.
  • the tab body 19 includes a body panel 20 which is defined by an upwardly directed rib 21 which extends about the periphery of the body panel 20 with the exception of one end thereof at whlch end the rib 21 terminates in two transversely spaced terminal ends 22.
  • the end of the tab body 19 where the rib 21 terminates generally corresponds to the configuration of the adjacent portion of the score line 15 and in the illustrated form of pull tab, is disposed upon a slightly curved line.
  • terminal ends 22 are relatively closely spaced, it will be seen that they deflne therebetween a ⁇ relatively stiff nose 23 which is engageable with the underlying panel portion 16 immediately adjacent the score line 15 for the purpose of exertmg a localized downward pressure on the removable panel portion 16 which is sufficient to effect the rupture of the end panel 14 along the adjacent portion of the score line 15.
  • the body panel 20 of the tab body 19 has formed in the central portion thereof a generally C-shaped c ut 24 which opens towards the nose 23.
  • the cut 24 terminates at the two ends thereof in small diameter apertures 25 which are for the purpose of preventing the accidental tearing of the body panel 20 as a continuation of the cut 24.
  • the cut line 24 defines a mounting ear 26 which is connected to the remainder of the body panel 20 along a hinge line which extends between the apertures 25.
  • the mounting ear 26 1s provided with an opening 27 therethrough through which the rivet 18 passes. The rivet 18 -serves to tightly clamp the mounting ear 26 against the underlying portion of the removable panel portion 16.
  • the pull tab 17 is advantageously formed of sheet metal and is of a one piece con-struction.
  • the structural details of the tab body 19 and the manner in which it is connected to the panel portion 16 may be utilized when the pull ring 28 is formed separately or when some other type of handle or lifting means is provided on the tab body 19.
  • An easy opening container member comprising a panel having -a weakening line defining a removable panel portion, and a pull tab for facilitating the initial rupture of said panel Iand the tearing out of said panel portion, said pull tab including a tab body, a mounting ear yattached to said tab body, and means permanently securing said mounting ear to said panel lportion with one end of said tab body aligned with an adjacent portion of said weakening Iline whereby when the ⁇ opposite end of said tabe is moved away from said panel portion said one tab end will exert a pressure on said panel portion along said weakening line, said tab having an uninterrupted peripheral reinfor-cing rib extending along each side thereof from said one end beyond said mounting ear, said reinforcing rib having terminal ends disposed at said one tab body end in spaced relation and defining at said one end a stiffened nose for applying a localized pressure on said panel portion.
  • An easy opening container member comprising a panel having a weakening line defining a removable panel portion, and a pull tab for facilitating the initial rupture of said panel portion, said pull tab including a tab body, Ia mounting ear attached to said tab body, and means permanently securing said mounting ear to said panel portion with one end ⁇ of said tab body aligned with an adjacent portion of said weakening line whereby when the opposite end of said tab is moved away from said panel portion said one tab end will exert a pressure on said panel Iportion along said weakening line, said mounting ear being formed from a central portion of said tab body and being defined by a generally C-shaped cut line terminating at opposite lends in small diameter holes to prevent the undesired tearing of said ear from ⁇ said tab body.
  • An easy opening container member comprising a panel having a weakening line defining a removable panel portion, and a pull tab for facilitating the initial rupture of said panel portion, said pull tab including a tab body, a mounting ear Iattached to said tab body, and means permanently securing said mounting ear to said panel portion with one end -of said tab body aligned with an adjacent portion of said weakening line whereby when the opposite end of said tab is moved away from said panel portion said one tab end will exert a pressure on said panel portion along said weakening line, said -container member being a container end, said panel being the end panel thereof, said panel portion constituting a major portion of said end panel, and said pull tab being completely within the outline of said panel portion at all times.
  • said pull tab also includes a handle hingedly connected to said tab body at the opposite end thereof, the hinge between said handle and said tab body being in the form of a connecting strap weakened by 4a centrally located aperture.
  • a pull tab for easy opening containers comprising a tab body having means at one end particularly adapted for applying an inwardly directed rupturing pressure on -a container panel when the opposite end thereof is moved outwardly, said tab body having a mounting ear formed from the central portion thereof, said mounting ear being ⁇ defined by a generally C-shaped cut line and being connected to said tab body along a hinge line.
  • pull tab of claim 13 wherein said pull tab also includes a handle hingedly connected to said tab body at the opposite end thereof, the hinge between said handle and said tab body being in the form of a connecting strap weakened by a centrally located aperture.
