Definitions
- the invention relates to the field of screw closure caps which typically include an internal threaded plastic insert and a metal outer shell.
- These capsules are typically intended for corking bottles containing alcoholic beverages, including wine.
- French Patents Nos. 2,792,617 and 2,793,216 describe a composite closure capsule in which said insert provides the technical functions of the capsule.
- French Patent No. 2,802,181 discloses a closure cap in which said shell is crimped to said insert, the capsule comprising means for giving weight and / or volume to said capsule above its sealing means.
- French Patent No. 2,803,827 describes a closure cap in which said insert is thin-walled.
- Screw closure capsules are also known whose threading is constituted by a deformation of the metal skirt of the capsule, as described for example in French Patent 2,387,165.
- screw cap capsules of the state of the art do not always have a satisfactory manual gripping level, insofar as the unscrewing of the capsule may require a torque, in particular a first opening torque, such that the fingers may tend to slide on the metal shell, which is generally cylindrical.
- An object of the invention is formed by closure caps of particular shape which are therefore more manageable, easier to screw / unscrew than those of the state of the art.
- Another object of the invention is constituted by capsules whose shape of the shell allows an immediate differentiation compared to commercially available capsules which are typically cylindrical.
- these capsules must meet the requirements of mechanical strength, in particular impact strength.
- Another object of the invention is constituted by a method making it possible to manufacture these capsules at high speed, the first subject of the invention.
- the composite capsules are manufactured by supplying the plastic inserts, the metal shells and assembling them.
- the plastic insert is formed by molding thermoplastic material, typically by injection.
- Metal shells are typically made by stamping tape or foil, usually aluminum or tin. Thus, in practice, it is known to produce industrially at high speed that cylindrical metal shells.
- the closure cap intended for screw-sealing a container intended to contain typically alcoholic beverages, typically a bottle having a neck with an external screw thread and a tamper-evident ring, comprises two parts rendered integral in rotation and axially by an assembly means, a) an inner part or insert of height h, made of plastics material, comprising an inner said head and a so-called inner skirt, said inner skirt comprising an internal thread on its inner surface intended to cooperate with the threading of said neck so as to be able to screw said capsule to said neck according to an axis of rotation or an axial direction, and b) an outer part or shell of height H, typically metallic or metal-based, comprising an outer head and an outer skirt masking all or part of said inner skirt opposite said capsule being typically dot e of a sealing means, a tamper-proof means and a means of first opening, and is characterized in that: 1) said outer skirt of said shell comprises at least a typically cylindrical portion of height Hl , of diameter D
- said radially expanded portion (43) and said typically cylindrical portion (42) of said outer skirt (41) typically have the same thickness Ep.
- the means of the invention can effectively solve the problems with regard to the capsules themselves. Indeed, the presence of an expanded radial portion on the skirt of said shell allows both to better manually grasp the capsule in particular for its unscrewing, and to differentiate from commercial capsules.
- the invention makes it possible to differentiate without increasing the height of the containers clogged with such capsules.
- the total height of a bottle capsulated can in many cases be a standard or a requirement imposed by one of the many actors in the chain from the producer or conditioner to the consumer.
- a beverage dispenser is led to change the spacing between its bottle storage shelves because the height of the bottles would be too large.
- these capsules have a high impact resistance, in particular because the radially expanded portion of the outer skirt has a thickness Ep substantially the same as that of the remainder of the radially unexpanded outer skirt, whereas the expanded zones of the state of the art show thinning of the wall. Indeed, it is advantageous that this be so insofar as this expanded part (43) is exposed to shocks and where it would therefore not be mechanically weaker than the rest of the metal shell (4) . This can be achieved in particular by the method according to the invention described next.
- FIGS. 1a, 2a, 3a, 4a, 5, 7a, 8a, 9a, 10a, 13a, 13b and 14a are axial sections of capsules (1) comprising a shell (4) according to the invention, said capsules being crimped onto a neck (2), while Figures lb, 2b, 3b, 4b, 6b, 7b, 8b, 9b, 10b and 14b are side views of the corresponding capsules (1).

- Figures 1 la and 1 lb correspond to two variants of the device (9).
- Figures 1e and 1d respectively represent the initial state (before radial expansion) and final state (after radial expansion).
- Figures 12a to 12b are similar to Figures 1e and 1d, but the elastomeric punch (95) has a sloping wall profile (950).
- FIGS. 12c and 12d schematize a radial expansion according to the prior art, FIG. 12c being similar to FIG. 1e, and FIG. 12d illustrating the rupture of the shell. when the radial expansion does not allow, as according to the invention, a progressive deformation of the shell (4 ') - from bottom to top as shown in Figures 1 to 12b.
- Figure 13b is a partial view of the capsule according to Figure 13a.
- Figs. 14c and 14d are enlarged views of said expanded portion (43) in the case where the insert (3) comprises a flexible annular tongue (302).
- FIGS. 15a to 15f and 17a to 17b are partial side views of said shell (4) and ornamental or manual gripping means (430) of said expanded portion (43).
- FIGS. 16a to 16f and 18d are top views of said shell (4) or capsule (1,
- 17c and 17d are axial half-sections (left side) of a capsule (1 ') placed on a neck before crimping in FIG. 17c and after crimping in FIG.
- FIGS. 18a to 18c are views of a shell (4) of which said cylindrical portion (42) comprises an amplitude deformation a '/ b' much smaller than the amplitude a / b of the deformation of said expanded part ( 43).
- Figure 18a is a view of the shell (4), while Figure 18b is an enlarged view of the portion surrounded by a dashed circle, top left, in Figure 18a.
- Figure 18c is a partial perspective side view of a portion of the cylindrical portion (42 ') of the outer skirt (41).
- said expanded portion (43) can typically form an annular ring, continuous or discontinuous, connecting, at its upper part, typically to said outer head (40), or possibly to said cylindrical portion (42), and at its lower part, to said cylindrical portion (42).
- said expanded portion (43) forms a continuous annular ring of cylindrical symmetry. In this case, it is this radial extra thickness which, on the one hand ensures a more firm manual gripping of the capsule, and on the other hand forms a very distinctive exterior sign. Said expanded portion (43) delimits an annular radial cavity (48) between rolls of diameter D1 and diameter D2.
- all or part of said inner skirt (31) of said insert (3) can cooperate with all or part of said typically cylindrical portion (42) of said outer skirt (41), so as to form in particular said connecting means.
- the insert (3) and said typically cylindrical portion (42) of the shell are of substantially the same diameter D1, so that said insert (3) can be introduced into said shell (4) without being excessive.
