Definitions

  • a container intended to receive one or more pouring assemblies is generally a can, or a bottle, a flask, a tube or the like, intended to contain a fluid product, for example liquid or pasty, or even a pulverulent product.
  • the container is mainly made of metal, of a material such as glass, ceramic or terracotta, or also of a plastic material such as polypropylene or polyethylene.
  • the container is a metal can made of steel or aluminum alloy for a liquid such as drink or sweetening syrup.
  • the pouring body is intended to be assembled with a ring delimiting an opening for filling and / or emptying a container.
  • the pouring body is a unitary or monobloc plastic part. The same applies to the closure cap to be mounted on the pouring body.
  • the pouring and closable assembly by removable mounting of the closure cap on the pouring body.
  • This removable mounting can consist of a screwing, an elastic stapling for example.
  • the structure of the current pouring bodies and / or closure cap is such that the efforts of mounting the pouring assembly on the container are significant.
  • the mounting on a container of such a pouring body with or without closure cap must allow a fastening sufficiently resistant to various constraints.
  • the assembly of the pouring body and the container must withstand the mechanical stresses (compression, traction and bending) of packaging or use.
  • the mechanical strength of the pouring body / container assembly can then be temporarily reduced by made of high temperature, which may cause separation, and therefore waste.
  • the structure of the pouring body can be altered due to plastic deformation of the pouring body or of the ring delimiting the opening of the container, which can lead to an unacceptable separation, for example during transport and / or use.
  • the resistance of the attachment of the pouring body and the ring delimiting the opening of the container is increased with respect to a determined value, by a large safety factor.
  • the invention aims to solve these problems, among other things, by reducing the efforts of fitting the pouring body assembly onto a ring delimiting an opening of a container.
  • the base of the side skirt of the capsule has a free edge inclined at an angle between 10 ° and 60 ° relative to the horizontal, the upper surface of the outer skirt of the pouring body located opposite this free edge after assembly of the pouring body and the closure cap being substantially horizontal.
  • the base of the lateral skirt of the capsule has a projecting recess which comes to bear on a part of the horizontal upper surface of the external skirt of the pouring body, after assembly of the pouring body and of the capsule.
  • the base of the lateral skirt of the capsule has a substantially horizontal free edge, the upper surface of the external skirt of the pouring body being frustoconical, the angle between this horizontal free edge and this upper surface being between 10 ° and 60 °.
  • the means of association of the capsule on the pouring body are for example a screwing or an elastic stapling.
  • the external skirt of the pouring body has an internal lateral bead located in the space delimited by the external skirt and the internal skirt of the pouring body.
  • the pouring body and the capsule may have an axis of symmetry, the pouring body comprising a drain and / or filling duct, substantially arranged along this axis.
  • the closure cap may include an internal lateral skirt projecting from a capsule bottom, this skirt being intended to penetrate into a pouring spout formed by the extension of the inner skirt of the pouring body.
  • the invention also relates to a method of placing a pouring assembly as described above, comprising a step of applying a force to the external skirt of the pouring body by pressing the base of the skirt of the cap on the part of the external skirt of the pouring body located to the right of the ring of the container, this support causing an elastic deformation of the external skirt of the pouring body and an enlargement of the space defined by the external skirt and the external skirt of the pouring body thus facilitating the passage of the container ring.
  • outside is understood with respect to the axis 5 of revolution of the pouring body 1 and of the closure cap 2 in the closed situation.
  • the pouring body 1 is intended to be rigidly associated with a container 6.
  • the container 6 comprises an opening 7, an annular ring 8 being situated at the edge of this opening 7.
  • the internal annular wall 9 is substantially vertical on a upper part 9 'and frustoconical on a lower part 9 ".
  • the annular ring 8 also comprises an upper annular wall 10 and an external annular wall 11.
  • the outer annular wall 11 is curved and its diameter measured with respect to the axis 5 decreases going from bottom to top according to FIG. 1.
  • the container 6 intended to receive one or more pouring bodies 1 is generally a can, a bottle, a bottle, a tube or the like.
  • This container 6 is generally intended to contain a fluid content, for example liquid or pasty, or even a pulverulent product.
  • the container 6 is mainly made of metal, glass, ceramic or terracotta, or even plastic, such as polypropylene or polyethylene.
  • the internal annular 9, upper annular 10 and external annular 11 walls of the ring 8 form in longitudinal section a concavity profile facing downwards, that is to say towards the container 6.
  • the lower part 12 of the pouring body 1 has, in longitudinal section, a concavity profile facing downwards of the pouring body 1.
  • the pouring body 1 comprises an external skirt 13 disposed below the thread 3.
  • the external contour of this external skirt 13 comprises an upper annular surface 14 which is substantially horizontal, an annular surface 15 which is substantially vertical, a connection leave 16 being arranged between the surfaces 14 and 15.
  • the internal contour of the skirt 13 comprises an annular surface 17 substantially horizontal, an annular surface 18 substantially vertical or slightly frustoconical, and a convex surface 19 of an internal lateral bead.
  • the geometry of the lower part 12 of the pouring body 1 and of the annular ring 8 of the container 6 allows a secure and tight snap-fitting of the pouring body onto the container.
  • the inner surface of the pouring body 1 may have at its lower free end contained in the container 6 of the slots 21 facilitating the total emptying of the container 6.
  • the pouring body 1 comprises a closed outlet pipe 22, before first opening by a transverse internal wall 23.
  • the entire pouring body as described above is produced in one piece by injection molding of a flexible plastic material, for example polyethylene.
  • the closure cap 2 comprises an external lateral skirt 25 supporting on its internal face the thread 4.
  • the fact of making a slope or a recess at the base 30 of the external lateral skirt 25 of the closure cap 2 makes it possible to reduce the bearing diameter of this capsule 2 on the pouring body 1 and promotes bending of the external skirt 13 when it snaps onto the ring 8 of the container 6.
  • the base 30 of the side skirt 25 has a free edge 31 inclined at an angle ⁇ between about 10 ° and 60 °. This angle a with respect to the horizontal is such that a concentration of stresses appears at a point on the surface 14 situated in the vertical extension of the horizontal annular surface 7 of the ring 8 of the container 6.
  • the external skirt 13 rocks outwards while turning substantially counterclockwise with respect to the stress concentration point.
  • the base 30 of the outer lateral skirt 25 of the capsule 2 has a recess 32.
  • This recess forms an annular projection turned towards the surface 14 when the capsule 2 is screwed onto the pouring body 1
  • This projection provides a concentration of stresses at a point on the surface 14 in a manner analogous to the internal lateral edge of the skirt 25 shown in FIG. 2.
