Definitions

  • the container end is provided with a tear strip which remains attached to the end at all times and the tear strip is provided at the starting end thereof with a lever to effect the initial rupture and the tearing of Vthe container end.
  • the tear strip is so proportioned relative to the container end and to the lever whereby the lever is engageable beneath the projection and lockable behind the projection so as to retain the lever and the 4tear strip in an out of the way position when the container is opened.
  • This invention relates in general to new and useful improvements in containers, and more particularly lto a novel container of the easy opening type.
  • Another object of this invention is to provide a novel container having a tear strip with one end thereof perinanently attached thereto, and the opposite end of the tear strip having a pull tab attached thereto, the pull tab having means for locking beneath a projection on the container to retain the strip and the pull tab in a stored position.
  • a further object of this invention is to provide -a novel container wherein the end of the container is provided with a tear strip which extends across a major portion thereof and the tear strip has a starting end and a terminal end with the terminal end being permanently secured to the container end and the tear strip starting end having attached thereto a pull tab to facilitate the tearing of the tear strip from tht remainder of the container end, and the relative proportions of the container end, the tear strip and the pull tab being such that the pull tab may be locked beneath a peripheral projection on the container when the tear strip is in a full open position with the tear strip substantially tensioned so that the tear strip and the pull tab are stored when the container is opened.
  • FIGURE 1 is a fragmentary top perspective View of a container formed in accordance with this: invention.
  • FIGURE 2 is an enlarged fragmentary plan view of the end of the container in FIGURE 1 and shows the specic details of the easy opening feature thereof.
  • FIGURE 3 is an enlarged fragmentary vertical sectional view taken along the line 3-3 of FIGURE 2.
  • FIGURE 4 is a sectional view similar to FIGURE 3 and shows the manner in which the initial rupture between the tear strip and the remainder of the container end is accomplished.
  • FIGURE 5 is a fragmentary vertical sectional view taken through the upper portion of the container of FIG- URE l and shows the tear strip as it approaches its fully open position and the pull tab atached lthere-to about to be locked beneath the peripheral projection of the container.
  • FIGURE ⁇ 6 is a sectional view similar to FIGURE 5 and shows the pull tab and tear strip in their stored positions.
  • FIGURE 7 is a fragmentary top perspective View of the container of FIGURE l in its fully open position.
  • a container for-med in accordance with this invention and generally referred to by the numeral 10.
  • the container is preferably in the form of a can having an end secured ⁇ thereto by means of a double seam and the illustrated container 10 is of this nature.
  • 'Ihe container or can 10 includes a conventional can body 11 to which there is secured a can end 12 formed in accordance with this invention.
  • the can end 12 is secured to the can body 11 by means of a conventional double seam 13.
  • the can end 12 has an end panel '14 of' which the central portion thereof is in the form of a tear strip 15.
  • the tear strip 15 is defined by a score line 17 which extends along the opposite sides and starting end of the tear strip 15.
  • the terminal end of the tear strip 15 is permanently secured to the remainder of the end panel 14 and the two ends of the score line 17 lterminate in spaced relation at opposite sides of the terminal end of the tear strip 15. ⁇
  • the pull tab 18 is formed of a single length of wire which is bent to have a generally rectangular outline.
  • the wire which is referred to by the numeral 19, includes a first end 20 and a pair of sides 21 and 22.
  • the sides 21 and 22 are reversely folded upon themselves as at 23 and 24 to define a pair of transversely spaced fulcrums 25.
  • the shaped wire 19 has a second end 26 which extends from the reversely folded portions 23 and 24.
  • the second end 26 normally will be formed by the two terminal end portions of the wire 19 with the juncture between the end portions of the wire 19, which juncture is referred to by the numeral 27, occurring at substantially the center of the end 26.
  • the pull tab 18 also includes a connecting strap 28.
  • One end of the connecting strap 28 is relatively wide and rolled upon itself to define a ⁇ sleeve 29.
  • the sleeve 29 receives the end 26 of the wire 19 and hingedly connects the wire member to the strap 28.
  • the opposite end ot' the strap 28 is rigidly secured to the starting end of the tear strip 15 by means of a rivet 30 which is integrally formed with the tear strip 15. At this time it is pointed out that the starting end of the tear strip 15 is pointed to facilitate the initial rupture of the end panel 14.
  • fulcrums 25 bear downwardly against a suppor-ting portion of the end panel 14 and an upwardly directed force is applied to the tear strip 15 through the end 26 of the wire member 19, the connecting strap 28 and the rivet 30.
  • a sufiicient lifting force may be readily exerted on the tear strip 15 in this manner to effect the initial rupture of the starting end of the tear strip 15 from the remainder of the end panel 14. The condition of the can end 12 after this initial rupture occurs is clearly shown in FIG- URE 4.
  • the pull tab 18 is moved in the direction of the arrow 31 in FIGURE 4 to simultaneously reverse the fold of the tear strip 15 back up on itself and to tear the tear strip from the end panel 14 along the score line 17.
  • the fulcrums of the wire member 19 are engaged with the double seam 13 in the manner shown in FIGURE 5 and the wire member 19 is swung outwardly and downwardly as shown by the arrow in FIGURE 5.
  • the fulcrums 25 pivot beneath the double seam 13 and the tear strip 15 is first drawn-outwardly and then downwardly until the wire member 19 assumes a substantially vertical position alongside the can body 11.
  • the wire member 19 reaches this position, as is shown in FIGURE 6, the tearing of the tear strip 15 relative -to the end panel 14 is completed.
  • the tear strip is now in its stored position and a dispensing opening 32 is formed in the can end 12.
  • the distance between the connection of ⁇ the tear strip to the pull tab and the terminal end of the tear strip is substantially equal to the total of the distance from the tear strip terminal end to the exterior surface of the double seam, the axial dimension of the double seam, and the distance from the fulcrums to the connection between the tear strip and the pull tab. In this manner, tensioning of the tear strip in the fully opened condition of the can 10 is assured.
  • a container comprising a container body having a closed end and a peripheral projection at said closed end, a tear strip in said container end having a star-ting end and a terminal end, said tear strip terminal end being permanently attached to the remainder of said container end,
  • said pull tab having means for locking said pull tab behind said peripheral projection in the full open position of said tear strip whereby said tear strip and said pull tab may be stored when said container is opened.
