Definitions

  • the invention relates to the field of containers with opening easy and especially the metal covers to easy opening.
  • the easy-opening lids have a generally peripheral incision in the case of containers for food products, as shown in FIGS. 1a to 1c, FIGS. 1a and 1b corresponding to easy-opening lids with bowl, or have a localized incision at a small portion of the cover panel in the case of a cover for a beverage can.
  • the incisions are defined by their profile and the residual metal thickness under the incision which is also called the "residual".
  • a profile is defined by the angle alpha of the incision and by the calculated width P of the bottom of the incision.
  • a typical incision is shown in Figure 2 where the angle alpha is 60 ° and the width P is 40 ⁇ m and is designated by "60P40".
  • US patent 4,132,328 is known in which the incision of an easy-opening cover is formed on a strip delimited between two zones formed by two punching stages, so as to increase the compression of said delimited strip and thus facilitate opening the cover.
  • Figure 7 shows in section an incision after crimping and sterilization, with cracks at the bottom of the incision characteristics that the present invention proposes otherwise delete entirely, at least reduce very strongly.
  • the problem is to find a way to manufacture, so reliable and economical, low residual COF whose bottom incisions is not cracked at the end of manufacture, nor after packaging of the product to be packaged.
  • said strip is located on the periphery of the central panel and the skirt inside of the edge to be crimped, and forms an inclined plane between said central panel and said skirt, as illustrated in Figures 3a and 3b, having the shape of a corner cone portion at the top 180 ° -2.beta.
  • said cover is a convercle with a peripheral counter-bowl, in which said strip is located at the periphery of the central panel and of said counter-bowl, and forms an inclined plane between said central panel and said counter-bowl, as illustrated in Figures 3c, 3f and 3g, having the shape of a portion of a cone angle at the top 180 ° -2.beta.
  • said cover is a partially open lid, for example a lid for a beverage can in which said strip forms a non-zero beta angle inclined plane bordering the part of said panel intended to be opened, as illustrated in Figures 3d and 3rd.
  • said strip does not close on itself, as in the previous cases.
  • the inclination of said incision strip can be oriented at an angle of +/- beta relative to said mean plane of the central panel, considered as a horizontal plane (see FIGS. 3a and 3b).
  • Said beta angle is generally between 5 ° and 45 °. Indeed, for a beta angle less than 5 °, the desired effect (reduction of cracks) obtained is relatively moderate. Furthermore, as the problem posed is solved with a beta angle less than 45 °, there is no technical interest in making an incision on an incision band having a slope greater than 45 °.
  • Said beta angle is preferably between 10 and 30 °. As the embodiments and the comparative tests will demonstrate, the means of the invention effectively solve the problem posed.
  • Figures 1a to 1c show, in axial section, different shapes of covers with easy opening (1) of the prior art.
  • These covers include a central panel (3) on which there is an incision (2) on the incision strip (6) in a horizontal plane, parallel to the mean plane (17) of the panel (3), and a crimping edge ( 4).
  • the central panel is provided with a rivet (7) which fixes a ring (8), the spout (9) of which is located in line with the incision (2) so as to ensure the opening by tilting of the ring.
  • the crimping edge (4) comprises a skirt (5), strongly inclined, connecting to said central panel, possibly by a bowl (20).
  • Figures 1a to 1c are distinguished by the presence of a bowl (20) in the case of FIGS. 1a and 1b, and by the position of the incision (2) located in the plane of said panel central in the case of FIGS. 1a and 1c, and at the bottom of the bowl (20) in the case of FIG. 1b.
  • Figure 2 shows in axial section an incision (2).
  • a incision (2) is defined, for a thickness E of the layer metallic, by an alpha angle, by a calculated value P of bottom (10) of the incision, by an R value of the thickness residual (11) (also called “residual").
  • the sides of the incision were designated by 16a and 16b.
  • Figures 3a, 3b and 3c show, in axial section similar to that of FIGS. 1a to 1c, portions of easy opening cover (1) according to the invention having a sloping incision band (6).
  • Figures 3a and 3b illustrate the position of the incision (2) on the incision strip (6) forming the bottom of the bowl (20).
  • This strip (6) has a slope of angle beta with respect to the plane (17), corresponding to the horizontal mean plane of said central panel (3).
  • said strip (6) has a slope of an angle + beta, while the angle is -beta in Figure 3b.
  • Figure 3c illustrates the position of the incision (2) on the incision band (6) forming the periphery of the beach central (3), externally limited by the counter-bowl (18).
  • This strip (6) has an angle slope + beta by relative to the plan (17).
  • FIG. 3f is a top view showing the incision strip (6) in the form of a hatched crown, the incision (2) passing through the center of this strip.
  • Figure 3f is an axial section along the axis BB of Figure 3f, showing that said strip (6) has the shape of a cone portion with an angle at the top equal to 180 ° - 2.beta.
  • Figures 3d and 3e relate to an opening cover partial beverage can.
  • Figure 3d is a top view and Figure 3e is a section along the axis A-A of Figure 3d.
  • the incision strip (6) does not form not a band closed on itself, but has the form a horseshoe, the open part of which remains attached to the central panel (3) of the cover.
  • the ring (8) is positioned on the side of this open part, and tilting forward just tear the incision (2) and fold inwards the box the tongue delimited by said incision (2).
  • Figure 7 similar to Figure 2, shows a section micrographic showing the presence of cracks (12) at the bottom incision (10).
  • the invention applies more particularly to covers with easy opening (1) in steel or aluminum or alloy aluminum, alpha angle between 40 and 120 °, thickness between 0.12 and 0.30 mm (nominal thickness of the metal strip intended to form the metal layer of the lid with easy opening), and of residual thickness R at the bottom of an incision greater than 40 ⁇ m.
  • the residual thickness value R is generally understood between 60 and 140 ⁇ m, depending on the nature of the metal strip, and according to the value of said nominal thickness.
  • the angle alpha is preferably between 40 ° and 60 ° and the width P at the bottom of the incision is between 10 and 40 ⁇ m.
  • These preferential values are those which correspond to the best ease of opening.
  • the invention also includes a method of manufacturing easy opening covers (1) in which said incision is obtained by punching, using a corner punch alpha, an incision strip (6) of a blank cover, in a vertical direction (19) perpendicular to the plane by means of said central panel (3), said incision strip having a non-zero beta angle slope.
  • the angle alpha can be between 40 and 120 °, and the beta angle is generally between 5 and 45 °.
  • Said incision strip (6) with a beta angle slope is formed by stamping metal strip in a manner known per se during the formation of the cover blank. Given the high precision of the tools used to manufacture covers, it suffices that said strip has a width of around 1 mm to be sure that said incision (2) will be always well positioned on said sloping strip (6) beta angle.
  • Said punch (13) can be oriented at a gamma angle by with respect to said perpendicular direction (19) between two extreme values such as one of these values corresponds to a punch having one of its vertical faces (16a), as shown in Figure 4a, the other value corresponding to a punch having the other of its faces (16b) vertical, as shown in Figure 6a.
  • the blank cover not incised is positioned on an appropriately shaped anvil so the incision band (6) is in abutment on said anvil during the action of said punch.
  • All of the easy-open lids were made to from 5182 alloy aluminum strip (designation according to Aluminum Association), nominal thickness of 270 ⁇ m, varnished on both sides, and in metallurgical condition H28 corresponding to a strongly hardened state, restored during opening).
  • Standard easy-opening covers (1) of 73 mm in diameter were manufactured, with a peripheral incision according to FIG. 3a, incision having a profile of the "60P40" type (alpha angle of 60 ° and a calculated value of dish at the bottom 40 ⁇ m incision).
  • the lids obtained were crimped onto boxes which were then sterilized in a standard manner (30 min at 125 ° C). Cuts were made on the covers as manufactured, on the covers after crimping and on the covers after sterilization, so as to be able to carry out observations under the microscope by reflection and to assess the presence and extent of cracks at the bottom of the incision. .
  • the residual metal layer under the incision is particularly sensitive to the action of corrosion due to the ingredients of the packaged products (possible presence of acids and / or salts), and the sensitivity to corrosion increases with the presence of cracks, or the presence of cracks of greater length.
  • the damage to the incision which can be quantified by the presence of cracks and the length of the cracks, and the resistance to corrosion.
