Definitions

  • the present invention relates to a pouring assembly and closure cap made of plastic material comprising a pouring body intended to be fixed to a container and a sealing capsule intended to close the pouring body and connected to the pouring body by a hinge.
  • Such pouring assemblies and closure caps have so far been produced in one piece by molding in a hard plastic material such as polypropylene.
  • the spring hinges provided on such assemblies between the pouring body and the stopper capsule correctly fulfill their function, which is to ensure that the capsule has two stable positions relative to the pouring body, only when they are produced made of hard plastic.
  • Such spring hinges are known, for example, from French patents 1 402 900 and 78 03 713.
  • patent application GB-A-2 193 193 discloses a pouring assembly and closure cap made of plastic material comprising a pouring body produced in a single first piece of flexible plastic material with means for fixing to a container, and, joined to the pouring body, a closure cap made in one piece of hard plastic material with a hinge and intended to close the pouring body in the closed position.
  • the hinge is a simple hinge and the means for fixing the pouring body comprise an outer ring of fingers which, when the capsule is joined to the pouring body, by fitting, on said fingers, a sleeve connected by the hinge to the capsule, are surrounded and therefore stiffened by said sleeve, before the assembly of the assembly by snap-fastening on a bottle neck.
  • the present invention relates to a pouring assembly and closure cap with spring hinge which, while being simple to manufacture, allows a tight fixing on a container neck, even when the neck has manufacturing defects.
  • the invention also relates to a pouring assembly and closure cap with spring hinge which, while being simple to manufacture, allows fixing by welding directly on the body of a flexible tube.
  • the pouring assembly and closure cap made of plastic material, comprises a pouring body made in a single first piece of flexible plastic material with means of attachment to a container, and, joined to the pouring body, a capsule plugging made in a single second piece of hard plastic with a hinge and intended to close the pouring body in the closed position.
  • the hinge is a bistable spring hinge ensuring the capsule two stable positions corresponding one to the open position and the other to the closed position.
  • the pouring body has a first connecting part with an undercut profile located between the fixing means and the hinge, so that the fixing means remain flexible after the stopper capsule has been joined to the pouring body.
  • the capsule has a second connecting part with undercut profile complementary to the first connecting part. The two parts are brought together in a single unit by overmolding the first part by the second part in the area of said connecting parts.
  • the realization of the pouring body in a flexible plastic material allows, either to form on the pouring body sealing means (lips, skirts, etc.) sufficiently flexible so that they compensate for possible manufacturing defects of the container neck during fixing the pouring body by screwing or snapping onto the neck, or to provide for fixing the pouring body directly by welding to the body of a flexible tube.
  • Said connecting parts can be located in the hinge area and in this case advantageously have the shape of a dovetail tenon and a dovetail mortise, respectively.
  • Said connecting parts can also be arranged around the entire periphery of the pouring body, and advantageously comprise in this case an external peripheral bead on the pouring body and an annular part with a profile complementary to the profile of said bead on a belt made in one piece with the capsule beyond the hinge.
  • the means for fixing the pouring body to the container may comprise a collar for direct fixing by welding of the pouring body to a flexible tube constituting the container, or else comprise an internal bead on an outer skirt of the pouring body, to cooperate by snap-fastening with an outer throat of the neck of a bottle or similar container.
  • Figure 1 is a side view of a pouring assembly and closure cap according to the invention, the capsule being shown in the open position;
  • Figure 2 is a vertical section on a larger scale of the assembly of Figure 1, the capsule being closed;
  • Figure 3 is a side view similar to Figure 1 of another embodiment of an assembly according to the invention;
  • Figure 4 is a vertical section, on a larger scale, of the assembly of Figure 3;
  • Figure 5 is a vertical section of a pouring assembly and closure cap for direct fixing by welding to the body of a flexible tube.
  • the pouring and sealing cap assembly made of plastic according to FIGS. 1 and 2 comprises a pouring body 1 and a capsule plug 2 connected to the pouring body 1 by a spring hinge 3.
  • the pouring body 1 essentially comprises an internal skirt 4 intended to cooperate in leaktight manner with the internal face of the neck 5 of a bottle 6, and an external skirt 7 intended to cooperate with the external face neck 5, the two skirts 4 and 7 being interconnected at their upper part by an annular connection zone 8.
  • the internal skirt 4 is extended upwards beyond the connection zone 8 in the form of a pouring spout 9.
  • a cover 10 connected by a thin veil 11 to the inner skirt 4 closes the latter, the cover 10 being able to be torn off using a pulling ring 12 during the first use.
  • the outer skirt 7 which has an inner bead 13 for fixing the pouring body 1 by snap-fastening on the neck 5 provided with an outer groove 14 is extended, at its lower end, by an outer rim 15 extending upwards under the shape of a diverging belt to the contact plane 16 between the pouring body 1 and the capsule 2, except in the area of the spring hinge 3.
  • the flange 15 ends, below the hinge 3, by an edge 17 with a profile in the shape of a tenon with an undercut, for example in a dovetail.
  • the entire pouring body as described above is made in one piece by injection molding of a flexible plastic material, for example polyethylene.
  • the closure cap 2 comprises an inner skirt 21 and an outer skirt 22 projecting downwards on a capsule bottom 23, the inner skirt 21 being intended to penetrate into the pouring spout 9 and the outer skirt 22 coming in the extension of the rim 15 of the pouring body 1.
  • the capsule 2 is injection molded in a hard plastic material such as polypropylene, in one piece with the spring hinge 3 and, between the latter and the edge 17 of the pouring body 1, with a connecting part 24 having a female profile in the form of an undercut mortise, for example in a dovetail.
  • the manufacture of the capsule 2 is carried out by overmolding the pouring body 1, that is to say the pouring body 1 is first manufactured by injection in a first mold, is then removed from this first mold and placed as an insert in a second mold in which the capsule 2, with the hinge 3 and the connecting part 24, is produced by overmolding of the pouring body 1 by the capsule 2 in the open position according to FIG. 1.
  • the overmolding is located at the zone of the hinge 3, that is to say that is to say limited to the molding of the edge 17 of the pouring body 1 by the connecting part 24 located below the hinge 3.
  • a pouring and capping capsule assembly comprises a pouring body 31, a belt 32, a capping capsule 33 and a spring hinge 34.
  • the pouring body 31 has an internal skirt 35 intended to cooperate with the internal face of a bottle neck not shown, an external skirt 36 intended to cooperate with the external face of the neck and having an internal bead 37 intended to cooperate by snap-fastening an outer groove of the neck, a cover 38 with tearing ring 39, and a pouring spout 40 projecting upwards on the connecting part 41 of the two skirts 35 and 36.
  • the connecting part 41 comprises an outer bead 42 projecting radially over the entire periphery.
  • the belt 32 includes an outer part 44 in the form of a spherical crown, extending the hemispherical capsule 33 below the contact plane 45 between the belt 32 and the capsule 33, and an internal frustoconical part 46 extend from the lower end of the part 44 upwards and inwards, ending in an annular part 47 which surrounds from the outside, around the entire periphery, the bead 42 of the pouring body 31 and has a female profile complementary to the profile of the bead 42.
