Definitions

  • the invention relates to the field of capping, and more specifically to the field of closure with metal screw caps.
  • the invention allows, by means of the use of a threaded plastic ring, to use containers or bottles with standard flat glass ring and closure caps with incorporated seal, possibly standard.
  • the Applicant has also recognized the possibility of implementing the invention with standard capping equipment, with relatively simple adaptations, and without substantially modifying either the capping rates or the usual working methods in the beverage packaging trade. and wine in particular. This is very important insofar as, in practice, a requirement for a change of habit or a modification of device or method that is too great could condemn an otherwise interesting invention.
  • the only movement to be carried out by the consumer is a rotational movement, in the usual opening direction which is anti-clockwise, with sufficient torque to break the bridges of the weakening line and, if necessary, detach the seal from the bottle neck.
  • a rotational movement in the usual opening direction which is anti-clockwise, with sufficient torque to break the bridges of the weakening line and, if necessary, detach the seal from the bottle neck.
  • the skilled person can also dose the bridge breaking force.
  • FIG. 1 represents a closed bottle neck according to the invention, with a left part in front view after removal of the stopper cap, and a right part in view in axial section in the vertical plane, with the stopper cap.
  • the left part shows the threaded plastic ring (3), with its left-hand thread (31), placed in contact with the lower edge (100) of the counter-ring (10) of the neck (1).
  • the right part shows, in section, in addition to the same threaded plastic ring (3) placed under the counter ring (10), the closure cap (2) provided with a head (26) and its sealing insert, here a seal (22) with an inner skirt (220), with its weakening line (270) situated above the thread (31) of the plastic ring (3), so that at the opening, the upper part unthreaded (23) is separated, while there remains on the neck (1) of the bottle the lower part (24) comprising the thread (28).
  • Figure 1a is an enlargement, in section, of the threaded plastic ring (3).
  • FIGS. 3a to 3c schematize the method according to the invention:
  • Figure 3a the capping turret (5), represented schematically by a circle, is supplied with bottles, the neck (1) of which has a standard flat glass ring, plastic threaded rings (3) and closure caps (2) .
  • Figure 3b using a ring (50) mounted on said turret and on which is placed said threaded plastic ring (3), said threaded plastic ring (3) is first forcefully placed under the bottom edge ( 100) of the counter-ring (10), said device, mounting of the threaded ring under the counter-ring of the flat ring.
  • FIG. 1 the capping turret (5), represented schematically by a circle, is supplied with bottles, the neck (1) of which has a standard flat glass ring, plastic threaded rings (3) and closure caps (2) .
  • Figure 3b using a ring (50) mounted on said turret and on which is placed said threaded plastic ring (3), said threaded plastic ring (3) is first force
  • FIG. 3b represents, in section, three phases of this step, the initial phase on the left of the figure, the intermediate phase in the center of the figure, and the final phase on the right of the figure.
  • Figure 3c the capsule (2) being placed on the neck (1) provided with said plastic ring (2), a crimping wheel (51) mounted on said turret (5) applies the skirt (27) of the capsule ( 2) and thus form said capsule thread (28).
  • Figure 1 representing the sealing means obtained according to the invention, where was carried the height H of the capsule (2), with indication of the heights 0, H / 2 and H.
  • said plastic ring (3) is left-hand threaded and said closure cap (2) has a weakening line (270) located above the thread (31) of said threaded ring (3), when said capsule is placed in position on said neck (1) provided with said threaded ring (3) for said assembly, so that, when opening by unscrewing in the usual direction, i.e. counterclockwise, the threaded part of the capsule (24) moves downward away from said head, so that said bridges are under tension, there is a tearing of said weakening line and release of the upper non-threaded part of the capsule (23) located above said line weakening (270), the threaded part of the capsule (24) remaining integral with the neck (1).
  • said plastic ring (3) is threaded to right and said closure cap (2) has a line of weakness (270) located below the thread (32) of said threaded ring and above said lower flange (33), when said capsule (2) is placed in position on said neck (1) provided with said ring (3) in view of said assembly, so that, when opened by unscrewing in the usual direction, i.e.
  • a conventional capping turret (5) is used and it is adapted to fix said plastic ring (3) by force and automatically under said counter ring (10 ), so that conventional capping equipment for corks can, with minimal modifications, ensure capping of bottles.
  • the capsules they must include plastic inserts sealing which can be chosen from existing inserts, typically, either flat or shaped seals (21) maintained applied to the bottom of said capsule on the face interior of said head by a retaining groove for said capsule, ie seals identical glued under the sky of the capsule or inside of said head, or even shaped joints (22) with inner skirt (220) allowing in particular a reclosure leakproof of said container in case of fractional consumption.
  • plastic inserts sealing can be chosen from existing inserts, typically, either flat or shaped seals (21) maintained applied to the bottom of said capsule on the face interior of said head by a retaining groove for said capsule, ie seals identical glued under the sky of the capsule or inside of said head, or even shaped joints (22) with inner skirt (220) allowing in particular a reclosure leakproof of said container in case of fractional consumption.
  • a flat seal capsule (21) is shown in Figure 2, while a flat seal capsule (21) shape (22) with skirt (220) is shown in Figure 1.
  • the inner diameter of the rings (3) in relation to the outside diameter of said neck (1) so that, after press fitting on the neck, the ring is made integral with the neck and is not free either in rotation or in axial displacement relative to said neck.
  • closure capsules to be used to implement the method according to the invention, and which, according to a first embodiment, include a weakening line (270) located on the upper part of said skirt (27), that is to say between said head (26) and the half-height (H / 2) of said skirt (27).
  • the weakening line (270) which must be located in this case above the thread (28) of the capsule, must in practice be located several millimeters above the latter, under penalty of risk of breaking bridges during crimping of the capsule with formation of the thread (28). In practice, this line (270) can be located above the lower edge (100) of said counter-ring (10).
  • these stopper capsules to be used to implement the method according to the invention may comprise, according to a second method, a weakening line (270) located on the lower part of said skirt (27), that is ie between the half-height of said skirt (27) and its lower end furthest from said head (26). This is the case illustrated in FIG. 2.
  • said weakening line (270) must be located between the threaded portion (28) of the capsule and the crimped portion (271) located below the bottom edge. (33) of the ring (3).
  • Another object of the invention is the use of metallic or metalloplastic capsules closure (2) with incorporated seal (21, 22) for sealing containers or bottles with neck (1) with a flat glass ring that is not threaded thanks to the use of plastic rings (3) threaded on the right or left, previously mounted under the counter ring (10) of the neck (1) of said containers or bottles.
  • Another object of the invention consists of the closure means comprising a container or bottle with neck (1) with a flat glass ring, a threaded plastic ring (3) mounted under the counter-ring (10) of said neck, and a metallic or metalloplastic capsule (2), with incorporated seal (21, 22), having a weakening line (270), crimped on said threaded plastic ring (3) mounted on said neck (1).
  • These means also have two modes depending on the direction of the thread of the plastic ring (3): According to a first embodiment, represented in FIG. 1, said plastic ring (3) is left-hand threaded and said weakening line (270) of the capsule (2) is located above the thread (28) of the capsule ( 2) corresponding to that (30) of said threaded ring (3).
  • said plastic ring (3) is threaded on the right and said weakening line (270) of the capsule (2) is located below the thread (29) of the capsule ( 2) corresponding to that (31) of said threaded ring (3).
  • the tool (50) surrounds the ring (3) in its threaded upper part and not in its more flexible and unthreaded lower part, which allows the ring to be force fitted without damaging it.
  • These means both in terms of the geometry of the ring and in terms of the manner of fitting, ensure quality assembly, that is to say without manufacturing incident and without quality defects on the neck fitted with a threaded ring.
  • the capping turret (5) also being supplied with closure caps (2) according to the invention, made of aluminum, the capsules are then crimped with formation of the left-hand thread (28) by knurling wheels (51), in a conventional manner, as shown in Figure 3c.
  • the cost of a PE ring is much lower than the average cost a quality cork stopper, so that the economic balance is favorable to plugging according to the present invention.
  • the stopping according to the invention eliminates all the problems brought by the stoppers which can sometimes be of variable quality, like any natural material. It has been verified that the organoleptic qualities of the wine are not appreciably modified by the seals (21, 22), at least when the wine is kept or stored in the cellar for an average period, typically a few years. Trials are underway with wines for aging over a longer storage period.
