Definitions

  • the present invention relates to the general field of packaging, and in particular the field of metal covers for containers of the can type. More particularly, it relates to the metal covers of the type including a removable part that is delimited by a scoreline and that is equipped with an opening member.
  • Some metal containers mainly the cans for the packaging of foodstuffs, are provided with a so-called “easy” opening system (or “EOE” for “Easy Open End”), avoiding the use of tools such as can-openers.
  • EEE Easy Opening System
  • a commonly implemented solution consists in a single-piece metal cover including two parts, i.e.:
  • the scoreline is torn by a handling of an opening member carried by the central panel, commonly known as the “opening ring”.
  • This type of opening member conventionally comprises three parts, arranged successively over its length, i.e.:
  • the opening member is flatten against the upper surface of the central panel.
  • the user is brought to operate the opening member in two successive and distinct steps.
  • the user grasps the opening member, generally by its central grasping part, then he moves it apart from the central part.
  • the opening member then forms a lever, so that its beak-shaped, peripheral incision part causes a local breaking of the scoreline.
  • This rotational operation leads to the tearing of two upstream portions, on either side of the longitudinal axis of the opening member.
  • the removable part of the cover is then locally bent inwardly, about a virtual axis that is oriented perpendicularly, or approximately perpendicularly, to the longitudinal axis of the opening member.
  • a second step of opening the user exerts a traction on the opening member so as to continue the tearing of the scoreline and to dissociate all or part of the removable part from the cover.
  • the opening member hence allows the transmission of the force applied by the user, and of the energy generated, to the removable part of the metal cover, so as to ensure the tearing of the metal along the scoreline.
  • the easiness of opening is defined by the level of force and energy required to break this scoreline, which is in practice the most possible reduced.
  • this depression is of the order of 600 to 700 mbars for canned corn, and of the order of 850 to 900 mbars for the canned, steam-cooked vegetables.
  • Such a structure then generates a punctual blocking of the opening during the tearing of the upstream portions of the scoreline.
  • the hardness increase of the material, and/or the decrease of the thicknesses, used for the cover may give rise to an influence of the rolling direction.
  • the tearing is liable not to propagate along the scoreline, as desired, but in the central closing panel.
  • the applicant has developed a new structure of easy opening metal cover, that makes it possible, no longer to punctually block the opening during the tearing of the upstream portions of the scoreline, but to progressively control the energy used for this tearing.
  • the metal cover according to the invention comprises:
  • the central part comprises a removable part that is delimited by a scoreline having a variable residual thickness and that is equipped with an opening member.
  • This opening member includes, on either side of a part for the fastening to the removable part, a peripheral incision part and a central grasping part.
  • the scoreline comprises:
  • the upstream and downstream portions are arranged on either side of a virtual axis extending perpendicularly to the longitudinal axis of the opening member, said virtual axis corresponding to the bend line generated on the removable part after a pivoting of said opening member and the tearing of said upstream portions.
  • each upstream portion of the scoreline includes, successively in the tearing direction, at least two sections:
  • the second section extends over at least 20%, preferably over at least 25%, still preferably between 25% and 60%, of the length of said upstream portion.
  • Said second section of each upstream portion of the scoreline includes:
  • the structure of the scoreline according to the invention hence allows entering the second sections whose tearing will continue progressively and at a higher level of effort.
  • the present invention also relates to a container, in particular of the metal can type, equipped with a metal cover as defined hereinabove.
  • the present invention also relates to a method for manufacturing a cover according to the invention, wherein the method comprises a step of incision of the scoreline into said cover, by means of an incision tool comprising an upper member (for example an incision block) and a lower member (for example an anvil) each carrying a profile.
  • an incision tool comprising an upper member (for example an incision block) and a lower member (for example an anvil) each carrying a profile.
  • each upstream portion of the scoreline includes, successively in the tearing direction, at least two sections:
  • the present invention also relates to the device for manufacturing a metal cover according to the invention, comprising an incision tool for forming the scoreline, wherein the incision tool comprises an upper member (for example, an incision block) and a lower member (for example, an anvil), each carrying an incision profile.
  • the incision tool comprises an upper member (for example, an incision block) and a lower member (for example, an anvil), each carrying an incision profile.
  • the profiles in incision position define, between each other, a space of variable width to generate the upstream portions of the scoreline according to the invention.
  • Each upstream portion of the scoreline includes, successively in the tearing direction, at least two sections:
  • FIG. 1 shows, in top view, a metal cover according to the invention
  • FIG. 2 schematically shows a cross-section of the scoreline formed in the metal cover

  • FIG. 4 schematically illustrates the tool for forming the scoreline according to the invention into the metal cover
  • FIG. 5 schematically shows the profile of incision of the upper member of the incision tool according to FIG. 4 , adapted to form a scoreline according to FIG. 3 ;
  • FIGS. 6 to 12 each schematically show a development of the longitudinal section of a variant of embodiment of an upstream portion of the scoreline formed in the metal cover, showing the variation of its residual thickness over its length.
  • the metal cover 1 shown in FIG. 1 , is intended to be assembled to the upper edge of a metal container body (not shown).
  • This container body is generally consisted of a bottom associated with the lower edge of a belt of lateral walls (of circular, square, rectangular cross-section, etc.).
  • the linking between the metal cover 1 and the upper edge of this container body is made in the conventional way, for example by a seaming technique.
  • This metal cover 1 is of the “easy opening” (or “EOE” for “Easy Open End”) type, avoiding the use of tools such as can-openers.

  • the peripheral part 3 may have any other shape (for example, square, rectangular), which would be adapted to the section of the container body (as the case may be, parallelepipedal).
  • the central part 2 has two faces ( FIG. 2 ):
  • the distance between these two faces 21 , 22 corresponds to the nominal thickness N of the central part 2 ( FIG. 2 ).
  • This nominal thickness N of the central part 2 is for example comprised between 0.14 and 0.28 mm, preferably between 0.16 and 0.25 mm.
  • the central part 2 comprises a removable part 4 intended to form the opening of access to the container content.
  • the removable part 4 is, on the one hand, delimited by a scoreline 5 , also called “incision line”, and on the other hand, equipped with an opening member 6 .
  • the opening member 6 is arranged at the upper face 21 of the central part 2 , covering the removable part 4 ( FIG. 1 ).

  • This opening member 6 conventionally includes three parts, successively arranged along a longitudinal axis 6 ′, i.e.:
  • the scoreline 5 consists in a narrowing of material, forming a lower-strength structure.
  • This scoreline 5 is herein complete (closed), and advantageously of circular shape ( FIG. 1 ). As an alternative, it could be partial (for example, in an arc of a circle) and/or have any other shape (square, rectangular, for example).

  • the upper surface 51 of this scoreline 5 is formed by an upper grove 53 provided in the upper face 21 of the central part 2 .
  • This scoreline 5 could also be formed, as an alternative or a complement, by a groove 54 that would be provided in the lower face 22 of the central part 2 (as schematically illustrated in FIG. 2 in discontinuous lines). As the case may be, this lower groove 54 also forms the lower surface 52 of the scoreline 5 .
  • the scoreline 5 comprises different portions, i.e.:
  • the two upstream portions 55 extend on either side of the longitudinal axis 6 ′ of the opening member 6 .
  • Each upstream portion 55 , on the one hand, and the downstream portion 56 , on the other hand, are herein separated by a virtual axis 10 shown in FIG. 1 .
  • the virtual axis 10 corresponds, at least approximately, to the bend line generated on the removable part 4 after the pivoting of the opening member 6 .
  • this virtual axis 10 extends perpendicularly to the longitudinal axis 6 ′ of the opening member 6 .
