- Heat sealing material for the can body A heat-sealing material is advantageously distributed at least on the receiving strip 211a of the can body 2, including on the weld in the case of a three-piece can (application of a so-called heat-sealing re-champi varnish on the weld).
- Heat sealing material means a material capable of being activated to provide a sealing (or bonding) function when subjected to heating (e.g. local heating by conduction or induction).
- This heat-sealing material is, for example, chosen from polypropylene or polyethylene (for example in the form of a heat-sealing varnish which advantageously consists of a polymer matrix and a polypropylene dispersion).
- the method of manufacturing the metal packaging 1 according to the invention comprises:
- the peelable membrane 3 is advantageously shaped (a sealing wall 31 and a peripheral strip 32), for example by stamping, before being placed in the box body 2.
- the peelable membrane 3 is then in the form of a pre-stamped cup. This prior shaping is useful for avoiding folds at the peripheral strip 32.
- a sealing material is advantageously added to the box body 2, where appropriate including on the weld by application of the so-called heat-sealing resurfacing varnish.
- the sealing step is advantageously carried out by a heat sealing operation.
- the sealing step is carried out by any suitable sealing tool 5, for example mandrels, segments, wheels.
- the heat sealing operation consists of applying heating to the sealing tool 5 and/or the receiving strip 211a of the box body 2.
- the suitable sealing tool can be:
- a direct heating emitter e.g. a heated sealing tool, e.g. among heated mandrels, heated segments, heated wheels
- a direct heating emitter e.g. a heated sealing tool, e.g. among heated mandrels, heated segments, heated wheels
- an indirect heating emitter for example induction heating of the sealing tool and/or the receiving strip 211a of the box body 2).
- a sealing step using a sealing tool 5, in the form of a mandrel, is for example described below in connection with figures 8 to 19.
- Figures 8 to 13 show a mandrel-type sealing tool having a first profile.
- Figures 14 to 19 show a mandrel-type sealing tool having a second profile.
- figures 8 to 10 or 14 to 16 represent a box body 2 and a peelable membrane 3, prior to a direct sealing step carried out by the mandrel 5.
- figures 11 to 13 or 17 to 19 illustrate the box body 2 and the peelable membrane 3, during the direct sealing step carried out by the mandrel 5.
- a mandrel 5 advantageously comprises two faces 51, 52 intended to cooperate with the peelable membrane 5, advantageously defined relative to a longitudinal axis 5’:
- peripheral face 52 intended to cooperate with the peripheral strip 32 of the peelable membrane 3 (and with the receiving strip 211a of the box body 2).
- the front face 51 advantageously extends perpendicular to the longitudinal axis 5’.
- the peripheral face 52 is of generally truncated cone shape, diverging from the front face 51.
- the front edge 521 of the peripheral face 52, at the level of the front face 51, is advantageously chamfered, for example according to a curved section.
- the diameter of this front edge 521 of the peripheral face 52 is less than the diameter of the receiving strip 211a of the box body 2.
- the peripheral face 52 of the mandrel 5 defines a non-zero angle, diverging from the front face 51, relative to the receiving strip 211a of the box body 2.
- the peripheral face 52 of the mandrel 5 defines an angle ranging from 5° to 11°, diverging from the front face 51, relative to the receiving strip 211a of the box body 2.
- the peripheral face 52 advantageously has an angle D ranging from 5° to 11° relative to the longitudinal axis 5’, diverging from the front face 51.
- the angle D is still preferably from 7.5° to 9.5°.
- the receiving strip 211a of the box body 2 advantageously has an angle equal to 0°, relative to said longitudinal axis 2’ of the side wall 21.
- the receiving strip 211a of the box body 2 advantageously has an angle ranging from 0° to 60° relative to the longitudinal axis 2' of said side wall 21. This angle is advantageously measured between the generator 211a' and the longitudinal axis 2' of said side wall 21.
- the receiving strip 211a is thus possibly preformed, before the sealing operation.
- the angle of the receiving strip 211a, relative to the longitudinal axis 2’ is for example chosen from:
- the height E of the peripheral face 52 is at least equal to, or even greater than, the height of the peripheral strip 32 of the peelable membrane 3.
- the height E of the peripheral face 52 is at least 3 mm.
- the peripheral face 52 of the mandrel 5 has a reservation Re (opposite the front face 51), at the level of the tab 35 of the peelable membrane 3.
- the peripheral face 52 of the mandrel 5 is thus offset locally relative to the longitudinal top 2161 of the rolled part 216.
- a longitudinal dimension Re1 (advantageously measured parallel to the longitudinal axis 5’) between the reservation Re and the longitudinal summit 2161 of the roll 216 is from 0 to 1.5 mm (figure 13).
- This technical feature is particularly interesting so that the tab 35 does not adhere during the sealing operation with the roll 216, which will facilitate the subsequent opening/peeling operation.
- the height E of the peripheral face 52 is less than the height of the peripheral strip 32 of the peelable membrane 3.
- the height E of the peripheral face 52 is 1.5 to 2.5 mm.
- the peripheral face 52 of the mandrel 5 is thus housed within the peelable membrane 3, without protruding relative to the free edge 321 of the peripheral strip 32.
- the height of the peripheral face 52 of the mandrel is less than the height of the peelable membrane 3.
- the peelable membrane 3 is advantageously shaped and fitted onto the mandrel 5.
- the front face 51 of the mandrel 5 cooperates with the sealing wall 31 of the peelable membrane 3; and the peripheral face 52 of the mandrel 5 cooperates with the peripheral strip 32 of the peelable membrane 3.
- the peelable membrane 3 is in a flat configuration, held against the front face 51 of the mandrel 5. And when the mandrel 5 is fitted into the can body 2, the peripheral strip 32 of the peelable membrane 5 is formed between the peripheral face 52 of the mandrel 5 and the receiving strip 211a of the can body 2.
- the mandrel 5 and the can body 2 are maneuvered in a relative translational movement, in approach, so that the peripheral face 52 of the mandrel 5 fits within the receiving strip 211a of the can body 2 (figures 11 to 13 or figures 17 to 19).
- This nesting here generates an expanding deformation (also called radial deformation) of the receiving strip 211a of the box body 2, in a general truncated cone shape.
- the extension of the perimeter of the mandrel allows to create a pressure or radial force to achieve the seal.
- peripheral strip 32 of the peelable membrane 3 is then sandwiched between the peripheral face 52 of the mandrel 5 and the receiving strip 211a of the box body 2.
- the peripheral strip 32 of the peelable membrane 3 is then sealed, in an optimal manner, on the receiving strip 211a of the box body 2.
- the nesting depth Pe (of the peripheral face 52 of the mandrel 5 within the receiving strip 211a of the box body 2) is for example 3 to 4.5 mm.
- the nesting depth Pe (advantageously measured parallel to the longitudinal axis 5’) is advantageously measured between the front face 51 of the mandrel 5 and the longitudinal top 2161 of the roll 216 (figure 12).
- the radial deformation Ra (measured at the level of the longitudinal vertex 2161 of the roll 216 and perpendicular to the longitudinal axis 5') is for example 0.2 to 0.8 mm, more preferably 0.35 to 0.55 mm (figure 12 or figure 18). Furthermore, in the case of a three-piece box, the filling is advantageously carried out after the sealing of the peelable membrane 3 on the box body 2; this peelable membrane 3 then forms the lower bottom of the box body 2.
- a bottom wall (not shown) is then crimped at the level of the second free edge 218 of the side wall 21 which is located opposite the roll 216.
- the filling is advantageously carried out before the sealing of the peelable membrane 3 on the box body 2.
- the peelable membrane 3 is attached to the box body 2 after it has been filled.
- the metal packaging 1 according to the invention has the advantage of presenting an optimization of metal consumption, in particular due to the combination of:
- This solution has the advantage of allowing an interior volume which is increased, with an equal quantity of metal.
- Another advantage of the invention is to provide a metal packaging which is dimensionally balanced (approximately the same diameter at the top and bottom).
