Definitions

  • the invention relates to an assembly comprising a container and a capping device that is equipped with a cap and allows said cap to be kept fixed to the neck of the container, thus avoiding loss of the cap in nature.
  • assemblies that include a container and a capping device that includes a cap and that allows the cap to be kept attached to the neck of the container.
  • a capping device that includes a cap and that allows the cap to be kept attached to the neck of the container.
  • the container includes a neck that is equipped with a dispensing orifice that allows the contents of the container to be poured, a support collar that protrudes radially relative to the axis of the neck, and a coupling washer that protrudes radially relative to the axis of the neck, and It is arranged between the support collar and the dispensing orifice.
  • the capping device includes a lower ring that is intended to be retained in the neck of the container, a cap that is intended to cover the orifice of the container so as to seal it, and an attachment device that attaches the cap to the lower ring.
  • the lower ring is held axially on the neck of the container by means of a coupling washer.
  • the coupling washer has a frusto-conical shape that tapers upwards, that is to say in the direction of the orifice in the container.
  • the coupling washer delimits, downwards, that is to say in a direction opposite to the orifice, a stop.
  • the lower ring includes radially inward projecting retaining elements. During assembly of the capping device on the neck of the container, the retaining elements slide against the frusto-conical surface of the coupling washer and subsequently interlock by elastic recovery behind the coupling washer. The lower ring is then retained between the coupling washer and the support collar.
  • the pull-out resistance of the lower ring is limited and consequently it does not allow, it cannot be guaranteed in a sufficiently reliable manner, that the cap remains permanently attached to the container
  • An idea on the basis of the invention is to propose an assembly that comprises a blow-molded container that is easier to make and that allows an increase in the tear resistance of the capping device intended to be permanently attached to the neck of the container and this without significantly increasing the weight of the container.
  • the invention provides an assembly comprising a blow-molded plastic container and that comprises a neck in turn comprising:
  • the neck has such dimensions that it is possible to use a lower ring with a larger section, in order to increase its pull-out resistance and without thereby considerably increasing the weight of the neck.
  • the neck has an internal diameter d1 which is advantageous because, on the one hand, it is large enough to allow a sufficient air flow to optimize blowing operations and, on the other hand, it is sufficiently reliable to limit the amount of material used for the manufacture of the neck.
  • such a capping device may have one or more of the following features.
  • the internal diameter of the cylindrical part is comprised between 25 and 27 mm, preferably between 25.5 and 26 mm and for example of the order of 25.70 mm.
  • the outer diameter of the cylindrical part is comprised between 27 and 29 mm, preferably between 27.5 and 28 mm and for example of the order of 27.7 mm.
  • the height of the cylindrical part is comprised between 2.80 and 2.90 mm, for example of the order of 2.87 mm.
  • the cylindrical part comprises a thickness comprised between 0.8 and 1.2 mm, for example of the order of 1 mm.
  • the neck has a weight comprised between 1.3 and 1.7 g, for example of the order of 1.4 g.
  • the lower ring has a height comprised between 3.36 and 3.66 mm for more than 50% of its periphery, for example of the order of 3.51 mm.
  • the cap comprises an external flap which, in a closed position of the cap, surrounds the neck of the container, the external flap comprising a downwardly projecting lug and having on an internal surface a projecting surface which, when the cap is in the closed position, it becomes interlocked by elastic recovery behind the coupling washer, the lower ring comprising a cutout in which the lug of the cap protrudes.
  • the lower ring has, in the area equipped with the cutout, a height comprised between 1.76 and 2.16 mm, for example of the order of 1.91 mm.
  • the coupling washer has a frusto-conical surface that tapers upwards and the lower ring comprises retaining elements that protrude radially inwardly and are configured to, during assembly of the capping device on the neck, slide against the frusto-conical surface of the coupling washer and subsequently interlock by elastic recovery behind the coupling washer.
  • the retaining elements are protrusions that protrude radially inwardly from the lower ring.
  • the lower ring has, at the height of the protrusions, a maximum radial dimension comprised between 1.68 and 1.98 mm, for example, of the order of 1.83 mm.
  • the joining device includes two resilient films that attach the outer peripheral flap and the second sector, the capping device also including a locking device configured to lock the cap in the tilted open position.
  • the locking device includes a tab arranged between the two resilient films and extending upward from the lower ring and a heel that projects radially outward from the outer peripheral flap, the heel being arranged to abut against the tab during the pivoting of the cap between a closed position and an open tilted position, the resilient films, the tab and the heel being configured in such a way that, during the pivoting movement of the cap between its closed position and its position tilted open, the resilient films are subjected to a tensile force that increases to an intermediate unstable position and subsequently decreases from said intermediate unstable position towards the open tilted position.
  • the axis X corresponds to the axis of revolution of the container.
  • the "radial” orientation is directed orthogonal to the axis X.
  • the terms “external” and “internal” are used to define the relative position of one element in relation to another, by reference to the axis X, an element close to the axis X is rated as well as internal as opposed to an external element located radially on the periphery.
  • upper and lower are used to define the relative position of one element in relation to another by reference to a position in which the orifice in the neck is directed upwards and the cap is in a closed position on the neck of the container, an element intended to be placed lower is designated by lower and an element intended to be positioned higher is designated by upper.
  • an assembly comprising a container 1 equipped with a neck 2 and a capping device 3 equipped with a cap 4 intended to cover the orifice of the container 1 so as to seal it will be described below.
  • Container 1 is for example a bottle.
  • the bottle has a capacity of 150 cl.
  • the container 1 is made of plastic material and is shaped by a blow molding process.
  • a manufacturing process includes a first stage during which a tubular preform having an orifice is made and a second stage during which the preform is placed in a blow mold and a compressed gas is injected into the interior of the tubular preform through said orifice in the preform so that the material stretches and becomes flat against the mold so that it takes the shape of said mold.
  • the neck 2 of the container 1 includes an upper end in which a dispensing orifice 5 is arranged that allows the contents of the container 1 to be poured.
  • the neck 2 of the container 1 includes a support collar 6 projecting radially outward and a coupling washer 7 projecting also radially outward and which is arranged axially between the support collar 6 and dispensing orifice 5.
  • a cylindrical part 8 is arranged axially between the support collar 6 and the dispensing orifice 5.
  • the coupling washer 7 has a frusto-conical shape that tapers upwards, that is to say in the direction of the dispensing orifice 5 of the container 1.
  • the coupling washer 7 delimits downward, that is to say in a direction opposite to the dispensing orifice 5, a stop.
  • the capping device 3 mainly represented in Figures 1 to 3 , includes a lower ring 9 that is retained in the neck 2 of the container 1, a cap 4 that is intended to cover the dispensing orifice 5 of the container 1 so that seals it and a attachment device 10 that attaches the cap 4 to the lower ring 9.
  • the cap 4 includes an upper wall 11 intended to be arranged orthogonally to the axis X opposite the dispensing orifice 5 of the neck 2, an outer peripheral flap 12 intended to surround the neck 2 of the container 1 and a internal flap 13 which, in the closed position of the cap 4, is inserted inside the dispensing orifice 5.
  • the outer peripheral flap 12 and the inner flap 13 project downwardly from the upper wall 11.
  • the cap 4 also includes an annular lip 14 that extends from the upper wall 11, radially between the outer peripheral flap 12 and the inner flap 13. When the cap 4 is in the closed position, the annular lip 14 and the inner flap 13 are in contact against the inner face of the neck 2 so as to ensure the sealing of the closure.
  • the cap 4 also includes a gripping rim 15, shown in Figures 1 and 2 , which projects radially outward.
  • the gripping rim 15 is advantageously arranged on the opposite side of the attachment device 10.
  • the gripping rim 15 thus forms a gripping surface intended to facilitate the visibility, interpretation and manipulation of the cap 4, mainly for the purpose of pivoting it to the tilted open position.
  • the cap 4 further includes a lug 16 arranged in an area diametrically opposite to the attachment device 10.
  • the lug 16 protrudes downwardly from the lower flange of the outer peripheral flap 12 into a cut-out 17 arranged in the lower ring 9.
  • the lug 16 comprises, on its internal surface, a projecting surface which, when the cap 4 is in the closed position, becomes interlocked, by elastic extension behind the support provided by the coupling washer 7.
  • the attachment device 10 is configured to allow the cap 4 to pivot between a closed position, shown in Figures 1, 2 , 3 and 5 , and a tilted open position, not shown, in which the cap 4 disengages from the dispensing orifice 5 and does not hinder the pouring of the contents of the container 1.
  • the attachment device 10 includes two resilient films 18 that attach the cap 4 and more particularly the outer peripheral flap 12 of the cap 4 to the lower ring 9.
  • the capping device 3 also includes a locking device, also shown in figure 3 , arranged to lock the cap 4 in the tilted open position.
  • the locking device includes a tab 19 that extends upwardly from the upper edge of the lower ring 9.
  • the tab 19 is arranged between the two resilient films 18.
  • the locking device further includes a heel 20 that protrudes radially toward the outer, from the outer peripheral flap 12 of the cap 4. The heel 20 is configured to abut against the tab 19 when the cap 4 is pivoted towards the tilted open position so as to lock the cap 4 in said tilted open position.
  • the resilient films 18, as well as the locking device are configured in such a way that, during a first part of the movement of the cap 4 from the released position towards the tilted open position, the two resilient films 18 are subjected, due to the support of the heel 20 on the tab 19, to a tensile force that increases to an intermediate unstable position and subsequently decreases from said intermediate unstable position to the tilted open position. This allows the cap 4 to be locked in the tilted open position.
  • the lower ring 9 is attached, before the first opening of the container 1, to the cap 4 by means of breakable bridges 21, visible in Figures 2 , 3 and 5 , intended to break during the opening of the cap 4.
  • breakable bridges 21 thus constitute evidence of inviolability. More particularly, the breakable bridges 21 are distributed around the axis X and join the upper edge of the lower ring 9 and the lower edge of the outer peripheral flap 12.
  • the lower ring 9 includes retaining elements 22, as shown in FIG. 5 , which makes it possible to retain the lower ring 9 on the neck 2.
  • the retaining elements 22 are protrusions projecting radially inward from the lower ring 9.
  • the protrusions have a radial dimension that increases from bottom to top, that is to say in the direction of the upper edge of the lower ring 9.
  • the lower ring 9 is thus axially immobilized on the neck 2 while it can rotate relative to it about the axis X. During this assembly, the lower ring 9 comes into abutment against the support collar 6, which makes it possible to protect breakable bridges 21.
  • the internal diameter of the neck 2 has its smallest dimension at the height of its cylindrical part 8 arranged axially between the coupling washer 7 and the support collar 6
  • the cylindrical part 8 has an internal diameter d1 comprised between 24 and 28 mm, advantageously between 25 and 27 mm, preferably between 25.5 and 26 mm and for example of the order of 25.70 mm.
  • Such an internal diameter d1 is advantageous because, on the one hand, it is large enough to allow a sufficient air flow during blowing operations and, on the other hand, it is sufficiently small to limit the amount of material used to manufacture the neck 2.
  • the thickness of the wall of the cylindrical part 8 of the neck 2 is comprised between 0.8 and 1.2 mm and preferably of the order of 1 mm.
  • the outer diameter d2 of the cylindrical part 8 is comprised between 25.6 mm and 30.4 mm, advantageously between 27 and 29 mm, preferably between 27.5 and 28 mm and for example of the order of 27.7 mm.
  • the cylindrical part 8 arranged between the coupling washer 7 has a height comprised between 2.70 and 3 mm, advantageously between 2.80 and 2.90 mm, for example of the order of 2.87 mm.
  • the weight of such a neck 2 is comprised between 1.3 and 1.7 g, for example of the order of 1.5 g, the neck 2 of the container 1 being defined as consisting of the cylindrical upper part of container 1 as shown in figures 4 and 6 .
  • the dimensions of the lower ring 9 are described below.
  • the lower ring 9 has a height h2 comprised between 3.36 and 3.66 mm, for example, of the order of 3.51 mm.
  • the lower ring 9 has a thickness of at least between 0.5 and 0.6 mm, for example of the order of 0.55 mm.
  • the lower ring 9 has a height h3 comprised between 1.76 and 2.16 mm, for example of the order of 1.91 mm.
  • the lower ring 9 has, at the height of the protrusions that form the retaining elements 22, a maximum radial dimension r1 comprised between 1.68 and 1.98 mm, for example, of the order of 1.83 mm.
