Definitions

  • the present invention refers to an improved plastic lid for closing a •can, obtained in a metallic sheet and which is of the type comprising a tubular body, with its lower edge affixing or incorporating a bottom wall and with its upper edge carrying, directly by means of a deformed portion of the tubular body or by means of an annular upper wall portion, a seat for the seating and retention of the press-fit lid.
  • the invention refers to the provision of a plastic lid for a can of the type considered above and which is used for containing products of progressive consumption, such as certain food articles.
  • Patent application PI0203950 (PCT/BR03/00030) of the same applicant discloses a plastic lid construction comprising, in a single piece: a sealing portion which is removably seated and retained in a seat medianly provided in an annular upper wall which has its external edge usually double seamed to the upper end of the tubular body; and a tamper evident portion, comprising a lower skirt to be seated around the upper end of the tubular body, and an upper ring, seated on the upper end of the tubular body and which is incorporated, externally, to the lower skirt and, internally, through breakable radial bridges, to an upper end of the sealing portion, which projects radially outwardly from the seat.
  • the tamper evident portion presents an interruption extending along the width of the upper ring and along at least part of the height of the lower skirt, along which is lodged a gripping tab which, when pulled, after the rupture of the tamper evident portion, allows achieving an easy and controlled opening of the lid.
  • the construction described above results in a reclosable plastic lid, of simple construction and relatively low cost, incorporating a gripping tab which facilitates the opening, as well as a reliable seal element which permits the prompt visualization of violation.
  • the object of the invention is to provide a reclosable plastic lid for the type of can considered herein and such as described in the patent application cited above, but presenting an improved construction, according to which the tamper evident portion becomes more resistant to involuntary ruptures when the plastic lid is submitted to certain usual forces and impacts during the closure, storage and shipping operations of said closed cans. Disclosure of the Invention
  • the improvement of the present invention is directed to a lid which comprises, in a single piece, a sealing portion, removably seated and retained in the seat and which is provided with an external edge projecting radially outwardly from the seat; a tamper evident portion comprising a lower skirt, to be seated around part of the upper end of the tubular body and which is superiorly incorporated, through bridges, to the external edge of the sealing portion, the tamper evident portion presenting an interruption extending along at least part of the height of the lower skirt, the sealing portion incorporating, at its external edge, a gripping tab projecting through said interruption of the tamper evident portion, said bridges being broken when submitted to a certain pulling force, which separates the tamper evident portion from the sealing portion upon the first opening of the lid.
  • the breakable bridges are axially disposed around a circumferential extension of the upper end of the tubular body of the can, in order to connect an upper end of the lower skirt with the external end of the sealing portion in points which are angularly spaced from each other.
  • the sealing portion extends radially, until the peripheral edge of the upper end of the tubular body of the can, superiorly covering and protecting the can, and having its external edge incorporating, inferiorly, through a plurality of breakable axial bridges, the lower skirt of the tamper evident portion.
  • the new axial arrangement of the breakable bridges generally seated around the upper end of the tubular body of the can, makes said bridges be submitted to a compressive force and not to a pulling force, when the lower skirt is forced upwardly, by impact of the lid against any other element, resisting much better to said forces and avoiding the undue rupture thereof.
  • Figure 1 is a perspective view of a plastic lid constructed according to an embodiment of the present invention and incorporating a tamper evident portion
  • Figure 2 is an exploded perspective view of the lid of figure 1, after the rupture of the tamper evident portion
  • Figure 3 is an upper plan view of the plastic lid illustrated in figure 1;
  • Figure 4 is a partial diametrical cross-sectional view of the lid illustrated in figures 1-3 and mounted to the upper end of a can, said section being taken according to line IV-IV of figure 3; and Figure 5 is a view similar to that of figure 4, but with the section being taken according to line N-V of figure 3.
  • the present lid can be applied to a metallic sheet can comprising a tubular body 10, with a lower end 11 securing a bottom wall 12 and with an upper end 13 securing, by a double seam 14, an annular upper wall 15, which defines, internally, a seat 16 for the hermetic seating of the lid 20.
  • the annular upper wall 15 can take the form of a structural ring, as illustrated in figures 4 and 5, or the form of an annular plate in the cans with great dimensions, such as the 18-liter cans.
  • both the annular upper wall 15 and the seat 16 may be achieved by different manners, provided that it allows for a hermetic and secure fitting of the lid 20 to the upper part of the can.
  • the construction of the annular upper wall 15 and the seat 16 is accomplished as described and claimed in patent application PI 9408643-5 granted to the same applicant in Brazil and in other countries (in the United States, US5899352 and in Europe, EPO 0706486) , and therefore will not be described in details in the present disclosure.
  • the lid 20 is preferably constructed in plastic material, transparent or not, comprising a sealing portion 21 of adequate construction, so as to be removably seated and retained in the seat 16, said sealing portion 21 presenting an external edge 21b which is seated on the upper end 13 of the tubular body 10 of the can.
  • the lid 20 further comprises, in a single piece with the sealing portion 21, a tamper evident portion 25 having a lower skirt 25a which is generally tightly seated around a circumferential extension of the upper end 13 of the tubular body 10, more particularly its double seam 14, and presenting an upper end 25b which is incorporated, by means of manually breakable bridges 26, to the external edge 21b of the sealing portion 21.
  • the bridges 26 connect the upper end 25b of the lower skirt 25a with the external edge 21b of the sealing portion 21 in points which are angularly spaced apart .
  • the bridges 26 are broken when submitted to a certain pulling force, which separates the tamper evident portion 25 from the sealing portion 21, upon the first opening of the lid 20.
  • the tamper evident portion 25 presents an interruption 25c, in its circumferential extension, extending along at least part of the height of the lower skirt 25a, said interruption 25c defining a certain circumferential spacing between respective confronting edges of the lower skirt 25a, on both sides of the interruption 25c.
  • the sealing portion 21 incorporates a gripping tab 27, axially downwardly projecting through said interruption 25c of the tamper evident portion 25, for example remaining substantially leveled with the lower skirt 25a.
  • the gripping tab 27 projects along the whole axial extension of the lower skirt 25a, but it can also project axially inferiorly beyond the axial extension of the lower skirt 25a.
  • the tamper evident portion 25 comprises at least one breakable lock 28, connecting the griping tab 27 with the lower skirt 25a.
  • the gripping tab 27 is manually operable only upon the rupture of part of the tamper evident portion 25, for example, upon the rupture of each breakable rod 28.
  • the lower skirt 25a incorporates the ends of a bridge 25d, circumferentially extended over the interruption 25c of the tamper evident portion 25 and over the gripping tab 27.
  • the bridge 25d presents a first end 25e, which is incorporated to the lower skirt 25a by connecting means 25f , which are broken when said first end 25e is forced away from the lower skirt 25a, for example, by being pulled radially outwardly from, in order to liberate the manual access to the gripping tab 27.
  • the bridge 25d has its first end 25e superposed to said lower skirt 25a and incorporated to the latter by two connecting means 25f, which are circumferentially spaced from each other.
  • the gripping tab 27 is inferiorly incorporated to the bridge 25d through a breakable lock 28, in the form of one or more axial bridges, which are manually broken upon the first opening of the lid.
  • the provision of the gripping tab 27 allows the sealing portion 21 to be easily removed from its seating condition on the seat 16, and also a controlled and progressive opening of the can, first in the region adjacent to the gripping tab 27, and subsequently in the remaining of the seat, preventing the stored product from being inadvertently taken out from the can.
  • the gripping tab 27 may present one of the massive and at least partially perforated forms, defining a tag, such as in the illustrated construction. It should be understood that the gripping tab 27 can be massive and formed from a respective portion of the lower skirt 25a, remaining perfectly leveled with the latter and maintaining a gap 29 therebetween.
  • the external edge 21b of the sealing portion 21 incorporates a small cylindrical lower flap 21c, which surrounds, preferably tightly, a circumferential extension of the upper end 13 of the tubular body 10 and from which the bridges 26 depend, being inferiorly incorporated to the upper end 25b of the lower skirt 25a.
  • the lower skirt 25a may incorporate a circumferential internal projection 25h, axially spaced from the external edge 21b of the sealing portion 21 and which is dimensioned to be seated and axially locked under the double seam 14 at the upper end 13 of the tubular body 10 and around the latter.
  • the external edge 21b of the sealing portion 21 incorporates an upper circumferential rib 25g, continuous or defined in segments and which projects over the upper end 13 of the tubular body 10, so as to be loosely and telescopically fitted externally or internally to the lower end 11 of another tubular body 10 stacked over said tubular body 10.
