Definitions

  • This invention particularly relates to an easyopening panel construction wherein the panel has a dispensing opening which is sealed by a sealing member, preferably in the form of plastic tape, which sealing member is bonded' to the inner surface of the panel and which is rlupturable in accordance with the outline of the dispensing opening to facilitate the dispensing of a product from an associated container.
  • a principal feature of this invention is to provide means for facilitating the initial rupture of a sealing member of the foregoing type and to effect the removal of that portion of the sealing member which is aligned with the dispensing opening in the panel.
  • the panel is provided with a readily removable portion along an edge of the dispensing opening which is in the form of a cutter and which cutter has connected thereto a pull tab of a construction to effect the pivoting of the cutter inwardly through the sealing member so as to initially rupture the sealing member.
  • Another feature of this invention resides in the fact that the pull tab is bonded to the cutter and the cutter is in turn bonded to the sealing member whereby after the initial rupture of the sealing member occurs, a pull on the pull tab will result in the exerting of a like pull on that portion of the sealing member aligned with the dispensing opening through the intermediate cutter whereby the pull tab, the cutter and that portion of the sealing member aligned with the dispensing opening may be removed as a unit.
  • a further feature of the invention resides in the fact that the pull tab has a base to which the pull tab is hingedly connected, and the base of the pull tab overlies the dispensing opening so as to prevent any foreign matter from entering thereinto, and the base is bonded to the sealing member through the dispensing opening to facilitate the tearing out of that portion of the sealing member aligned with the dispensing Opening.
  • FIGURE l is a fragmentary top perspective view of an easy opening container incorporating the easy opening panel construction of this invention.
  • FIGURE 2 is an enlarged fragmentary plan view of the upper end of the container of FIGURE l.
  • FIGURE 3 is an enlarged fragmentary vertical sectional view taken along the line 3-3 of lFIGURE l.
  • FIGURE 4 is an enlarged sectional view taken along the line 4-4 of FIGURE 3 and shows the specific outline of the pull tab and the associated base.
  • FIGURE 5 is an enlarged fragmentary horizontal sectional view taken along the line 5-5 of FIGURE 3.
  • FIGURE 6 is an enlarged fragmentary vertical sectional view taken along the line 6 6 of FIGURE 5.
  • FIGURE 7 is an enlarged fragmentary vertical sec- United States Patent C) 3,371,318 Patented Mar. 5, 1968 2 tional view similar to FIGURE 3 and shows the pull tab moved to a slightly elevated position and the cutter having pivoted with the pull tab and having effected the initial rupture of the sealing member.
  • FIGURE 8 is an enlarged fragmentary transverse vertical sectional view taken along the line 8 8 of FIG- URE 7.
  • FIGURE l an easy opening container formed in accordance with this invention, the container being generally referred to by the number 10.
  • the illustrated container is in the form of a can and includes a conventional can body 11 to which there is secured a can end, which is generally referred to by the numeral 12, by means of a conventional double seam 13.
  • the can end 12 is provided with a panel 14 which is the customary end panel.
  • the end panel 14 In order to facilitate the dispensing of the product packaged within the container 10, the end panel 14, as is best shown in FIGURE 5, is provided with a dispensing opening 15 which is dened by a out edge 16. At one end of the dispensing opening 15 there is a cutter 17 which is triangular in outline and which has a pointed end 18 facing away from the dispensing opening 15.
  • the cutter 17 is primarily defined by cuts 20 and remains integrally connected to the end panel 14 only by means of a pair of very short connecting straps 21.
  • the metal of the end panel 14 at the connecting straps 21 is reduced in thickness by scoring so as to readily facilitate the breaking away of the cutter 17 from the end panel 14.
  • the sealing member 22 is preferably in the form of a generally rectangular piece of plastic tape which is bonded to the underside of the end panel 14 in any desired manner.
  • a special adhesive may be provided.
  • the plastic tape sealing member may be directly heat bonded to the enamel coating which is conventionally found on the inner surface of can ends.
  • the purpose of the cutter 17 is to facilitate the initial rupturing of the sealing member 22.
  • a pull tab unit which is generally referred to by the numeral 24.
  • the pull tab unit 24 includes a pull tab 25 which includes a generally U-shaped portion 26 having a cross bar 27 extending across the ends thereof.
  • the cross bar 27 is provided with a projecting portion 28 which generally conforms to the outline of the. cutter 17.
  • the pull tab unit 24 also includes a base 29.
  • the base 29 is integrally connected to the cross bar 27 and due to the resiliency of the plastic material from which the pull tab unit 24 is formed, has a hinge connection with the cross -bar 24.
  • the base 29 is of a size and outline to fully cover the dispensing opening 15 and normally rests on the outer surface of the end panel 14 surrounding the dispensing opening 16.
  • the projection 28 is bonded to the cutter 17
  • the base 29 is bonded to the sealing member or tape 22 through the dispensing opening 15.
  • the sealing member of tape 52 performs the necessary function of sealing the dispensing opening 15 and the cuts 20. It will also be apparent that the base 29 performs the function of covering the dispensing opening 22 externally so as to prevent the entrance of foreign matter into the dispensing opening. Thus from a packaging standpoint, the easy opening panel construction is an acceptable one.
  • the cutter 17 has been illustrated as positioned adjacent the periphery of the end panel 14, it is to be understood that if desired, the easy opening construction could be rotated 180 degrees so that the cutter 17 may be positioned adjacent the center of the end panel 14. This, of course, is merely a question of orientation which may be of any desired arrangement.
  • An easy opening panel construction for a container comprising a dispensing opening in said panel, a rupturable sealing member secured to said panel surrounding said dispensing opening and sealing said panel, and
  • means for facilitating the rupturing of said sealing member including a cutter formed from the material of said panel and a pull tab connected to said cutter for moving said cutter through said sealing member.
