  • the body 202 also displays an annular, radially and outwardly extending flange 216 configured to be attached to a container in the form of a paper or paper board carton (see Fig. 13).
  • the description below considers that the terms“upwards” correspond to a direction that is generally parallel to the central axis A and that goes from the second opening 212 towards the first opening 208, whereas the terms and“downwards” correspond to the opposite direction.
  • the terms“top” -“bottom” and“upper”-“lower”, correspond to relative positions with reference to this direction and the terms“inner” -“outer” correspond to correspond to relative positions with reference to a direction which is perpendicular to this direction.

  • the upper separation line 342 extends circumferentially around the cap 300 between a first endpoint 350 and a second endpoint 352 (see Fig. 7), which endpoints 350, 352 define between them a non-breakable second, upper bridge section 354 configured to permanently connect the lid portion 302 to the linking portion 304.
  • the lower and upper separation or break lines 340, 342 are adapted to be broken during a first opening of the closure device 100. Consequently, prior to the first opening the retainment portion 306 and the linking portion 304 are connected to each other along the lower break line 340, continuously or discontinuously, and during the first opening the retainment portion 306 and the linking portion 304 are configured to be separated from each other along this line 340. Likewise, prior to the first opening the lid portion 302 and the linking portion 304 are connected to each other along the upper break line 342, continuously or discontinuously, and during the first opening the lid portion 302 and the linking portion 304 are configured to be separated from each other along this line 342.
  • the lower and upper bridge sections 348, 354 are arranged at opposites sides of the cap 300 such that the bridge sections 348, 354, or at least sub-sections 356, 358 thereof (see Figs. 11 and 12), are arranged symmetrically about the central axis A.

  • the circumferential extent or distance a of the lower bridge section 348 may preferably be equal to or larger than the circumferential extent or distance b of the upper bridge section 354. However, in other embodiments the circumferential distance a may be smaller than the circumferential distance b. Consequently, the circumferential distance a of the lower bridge section 348 does not have to be equal to the circumferential extent b of the upper bridge section 354. This is illustrated in Fig. 11, which shows a situation where the circumferential extent a of the lower bridge section 348 is larger than the circumferential extent b of the upper bridge section 354, and where the lower bridge section 348 comprises a sub-section 356 that is symmetrical to the upper bridge section 354 about the axis A.

  • the distance between the first and second planes PI, P2, thus defining the height of the linking portion 306, may preferably be at least 1 mm to ensure sufficient strength of the linking portion 306, but should preferably not be more than 10 mm in order not to compromise the flexibility of the same. Consequently, the distance between the planes PI and P2 may preferably within the range of 1-10 mm. However, more preferably the distance may be within the range of 1-8 mm or 1-3 mm.
  • the lower separation line 340 is, in the closed position, arranged below the ridge 222, i.e. at an axial distance D1 from the dispensing opening 208 that is larger than the axial distance D2 between the ridge 222 and the dispensing opening 208 (see Fig. 3 : the axial distance being the distance measured along the in the direction of the longitudinal, central axis A).
  • the upper separation line 342 is positioned, in the axial direction of the pour spout 200, approximately level with the ridge 222, i.e. at an axial distance from the dispensing opening 208 that is approximately equal to the axial distance between the ridge 222 and the dispensing opening 208.
  • the first plane PI defined by the lower separation or break line 340 and the lower bridge section 348, and the second plane P2, defined by the upper separation or break line 342 and the upper bridge section 354, need not be parallel.

Abstract

L'invention concerne un dispositif de fermeture (100) comprenant un bec verseur (200) et un capuchon (300), le capuchon comprenant une portion couvercle (302), une portion de liaison (304) et une portion de retenue (306), la portion de liaison reliant de façon permanente la portion couvercle à la portion de retenue et la portion de retenue étant retenue en permanence autour du bec verseur, la portion couvercle étant agencée de manière refermable sur le bec verseur, ce qui permet d'amener le dispositif de fermeture entre une position ouverte et une position fermée. Le capuchon comprend des première et seconde lignes de séparation (340, 342) le long desquelles le capuchon est conçu pour se séparer lorsque le dispositif de fermeture est amené de la position fermée à la position ouverte. La première ligne de séparation s'étend de manière circonférentielle autour du capuchon, entre un premier point d'extrémité et un second point d'extrémité, définissant entre eux une première section de pont non cassable (348), conçue pour relier de façon permanente la portion de retenue à la portion de liaison, ladite première section de pont ayant une étendue circonférentielle (a) qui est inférieure à 90°. La seconde ligne de séparation s'étend de manière circonférentielle autour du capuchon, entre un premier point d'extrémité et un second point d'extrémité, définissant entre eux une seconde section de pont non cassable (354) conçue pour relier de façon permanente la portion couvercle à la portion de liaison, ladite seconde section de pont ayant une étendue circonférentielle (β) qui est inférieure à 90°. La première section de pont et la seconde section de pont sont situées sur des côtés opposés du capuchon. L'invention concerne également un ensemble comprenant un récipient et un tel dispositif de fermeture.
