Definitions

  • ABSTRACT A can end of the easy opening type includes an end panel having a dispensing aperture and a partially preformed vent hole.
  • An easy opening tab including a portion adapted to slide between closed and opened positions over the dispensing aperture includes a flip-' over finger engageable portion which is doublebacked over the sliding portion when the tab is in the closed position.
  • a closure panel puncturing projection extends from the flip-over portion of the tab so as to engage the partially pre-formed vent hole when the flip-over portion is pivoted to a substantially upright position.
  • This invention relates to easy opening containers including easy opening cans having finger engageable tabs for use in opening cans.
  • the most commercially successful easy opening can of the tab-type has utilized a tab which is formed by scoring acan end panel and removed by grasping a ring attached thereto with the'resulting ripping of the tab from the end panel along the score lines.
  • Aluminum is usually utilized for ring-tab ends of this type because of I its soft and malleable qualities whi'ch allow the use of substantial residual scoring depths while still permitting removal of the tabs by hand.
  • aluminum can ends of this type do present a number of problems.
  • aluminum is expensive and, due to its low strength relative to steel, large quantities of aluminum must be utilized in providing can ends of sufficient gauge to withstand the internal pressures generated within the cans.
  • aluminum is also the tab from the end panel uponopening. Although it is possible to slide the tab under the raised rim again to effect reclosing, separation of the tab from the end panel usually results in the loss or contamination of the tab.
  • Another problem resulting from this arrangement is the cost of riveting the ring to the tab.
  • aluminum can ends of the ring-tab type are not particularly easy to open. In general, more than one hand is required for opening. Furthermore, there is substantial ease.
  • the containerindustry has considered the .use of steel in easy opening can ends.
  • the hardness of steel makes its use in otherwise conventional ring-tab ends impractical, for a number of reasons.
  • First, the residual scoring thicknesses of asteel can end of this type must be small and must be maintained within very close tolerances to assure a line of weakness which will per mit removal of the tabs from the can end.
  • Second, the hardness of steel makes fora rather short tool life for the punches and dies which are utilized in scoring the steel.
  • a preferred embodiment of the invention comprises a closure panel having a dispensing aperture therein and an at least partially pre-formed vent hole with aneasy opening tab including a sliding portion closing the dispensing aperture, a flip-over portion having a hinged connection with the sliding portion and a vent hole puncturing portion extending from the flipover portion.
  • the flip-over portion Prior to opening the closure, the flip-over portion is double-backed overthe sliding portion with the vent hole puncturing means extending away from the closure panel.
  • the puncturing portion engages the closure panel in the vicinity of the partially pre-formed vent hole.
  • the flip-over tab acts with another important aspect of the invention, the flipover portion continues to pivot about the hinge connection while cooperating with the panel adjacent the vent hole opening to slide the sliding portion of the tab to a position opening the dispensing aperture.
  • FIG. 1 is a plan view for a can end embodying the invention
  • FIG. 2 is a sectional view of the can end of FIG. 1 taken along section line 2-2 FIG. '1
  • FIG. 1 taken along section line 22 representing two different phases of the can openin'g'process
  • FIG. 7 is a plan view of another can end embodying the invention?
  • FIG. 8 is a sectional view of the can endof FIG. 7
  • FIG. 9 is a sectional view of the can end, of FIG. 8 taken along section line 99. v
  • a steel can end 10 carries a flip-over tab 12 which closes a dispensing aperture'14 in a central end panel 16.
  • the tab 12 includes a sliding portion 18 which covers the dispensing aperture 14, a flip-over portion 20 which is adapted to be engaged by the fingers of the consumer, and aprojection 22 which is .adapted to puncture a partially pre-formed vent hole 24 located in the central end panel 16.
  • the sliding portion 18 is hel in place'within a-track 26 formed by triple-folding the edges 28 along opposite sides of the dispensing aperture 14. Specifically, the sides28 are double-folded over the exterior of the sliding portion 18 with the single fold along the raw edge 30 of the end panel 16 being located on the interior side of the sliding portion 18.
  • the dispensing aperture is sealed closed by providing a plastic sealant material 32, e. g., plastisol, along the As best shown in FIGS land '2,the end 34"ofthe sliding-portion 18 which islocated adjacent the chuck wall 36 of the end 10 is received beneath the raised lip 38 of the end panel 16 along the edge of the dispensing aperture 14.
  • the plastisol 32 also extends along the end 34 of the sliding portion" 18 so as to form' a seal with the end panel 16.
  • the'plastisol 32 forms a seal between the sliding portion 18 and the end of the dispensing aperture adjacent the vent hole 24.
  • the vent hole v24 is partially pre-formed by lancing the end panel 16 along a 300 are 40 with a bridgingconnection 42 to the remainder of the end'panel being located on the side op-- posite the dispensing aperture 14.
  • This bridging connection 42 is particularly important since it prevents the cover 43 which extends over the vent hole 24 from falling into the cans at the time the can is opened.
  • vent hole 24 ismaintained in the closed condition by a plastisol sealant 44 which extends along the 300 are 40 between the vent hole cover and the remainder of the central panel along the edge 46 of the partially pre-formed vent hole.
  • a plastisol sealant 44 which extends along the 300 are 40 between the vent hole cover and the remainder of the central panel along the edge 46 of the partially pre-formed vent hole.
  • the vent hole construction is capable of preventing the-premature ventingof the can.
  • the lancing of the end panel 16 to form the partially pre-formed vent hole would produce a friction fit between the edge 46 of the vent hole along the are 40 and an edge 48 of the vent hole cover 43. This construction prevents the vent hole-cover 43 from being blown out of the can.
  • the plastisol 44 prevents any leakage between the cover and the end panel at the edges 46 and 48. Furthermore, this particular lanced configuration is, from the manufacturing standpoint, easy toachieve. Finally, the vent hole cover 43 is domed or. bubbled so as to achieve the optimum cooperation between the puncturing projection 22 which isarcuate in crosss'ection as shown in FIG. 4 and the cover 43 which will now be described with reference 'toFIGS. 2, 5 and 6.
  • the flip-over portion 20 acts as a lever arm pivoting atthe hinge connection 52 between.the flip-over, portion'20 and the sliding portion 18.
  • the puncturing portion-22 serves as a much shorter lever arm between the hinge connection 52 and the vent hole to be punctu'red.
  • the projection 22 cooperateswith the edge 46 of the vent hole 24 so as to slide the portion l8'to an open position once the pressure on the sliding tab has been reduced through venting of the can and the flip-over portion 20 has been laid against the central end panel 16 in a position opposite the dispensing aperture 14 as shown in FIG. 6.
  • a single motion of the flip-over tab'from the position shown in FIG. 2 to the position shown in FIG. 6 accomplishes venting of the can which in turn permits the sliding portion 18 to move with ease to the position shown in FIG. 6 through the cooperation ofthe puncturing projection 22 and the vent hole 24.
  • the simple opening procedure may be. accomplished with one hand by placing the thumb beneath the double-backed flip-over portion 20 and moving the tab through an arcuate motion of about the hinge connection 52. Note that the tab 12 remains with the can end 10 after opening which is extremely advantageous from an standpoint.
  • a raised lip 68 extends along the Opposite end portions of the sides of the aperture 14.
  • the sliding portion 18 of the tab extends through a slit 72 located at the end of the lip 68 between the aperture 14 and the partially pre-formed vent hole 24.
  • cars or nibs 74 which are located between the raised lip 60 and the raised lip 68 extend beneath the sliding portion 18.
  • Plastisol sealant 76 extends along the slit 72 and around the dispensing aperture 14 so as to provide a seal for the contents within the can before opening the can end in the manner shown in FIGS. l-6.
  • the tab construction serves as a tool offering a mechanical advantage in the opening of a can end and steel does have certain ecologicaladvantages, the preferred embodiments have been described as steel can ends. However, another metal such as aluminum might be utilized but is by no means necessary in practicing the invention due to the mechanical'advantage inherent in this tab construction. 7
  • the flip-over tab has been described in terms of a can end adapted to be double-seamed to the can body as shown in dotted lines in FIG. 2.
  • the flip-over tabof this type could be embodied in a number of different types of closures for containers including a crown closure for a bottle.
  • a closure of the easy opening type comprising:
  • an easyopening tab including a sliding portion closing said dispensing aperture, a flip-over portion having a hinged connection with said sliding portion, and a vent hole puncturing portion extending from said flipover portion, said flip-over portion being doublebacked over said sliding portion when said tab is in the closed position with said vent hole puncturing portion extending away from said closure panel, said vent hole puncturing portion contacting said partially pre-formed vent hole when said flip-over portion is pivoted about said hinged connection to a position extending outwardly away from said sliding portion, said flip-over portion forming a lever having a fulcrum at said hinged connection, the overall length of the lever arm of said flip-over portion being longer than the. distance from the point of contact between'said partially pre-formed vent hole and said hinged connection so as to provide asubstantial mechanical advantage in puncturing said end panel at said partially pre-formed vent hole.
  • vent hole puncturing portion cooperates with said panel adjacent said vent hole after puncturing so as to slide said sliding portion to open said dispensing aperture as said flipover portion is moved toward said vent hole.
  • closure of claim 1 further comprising a plastic sealant forming a seal between said tab and said closure at said dispensing aperture before opening.
