Definitions

  • the present invention relates to a method and a machine for manufacturing a cap for a container neck as known from the patent EP-A-0 619168 , on which the preamble of claims 1 and 9 is based. It also relates to a plug as obtained by this method of manufacture.
  • the invention relates, in general, to plugs comprising a skirt which surrounds the neck of a container and a lower part of which, when it is considered that this neck extends vertically with its upwardly directed mouth, is intended to to remain around the neck after the first opening of the cap, while the rest of the skirt, that is to say the upper part, is provided removable relative to the neck, while being initially connected to the non-removable bottom part the skirt by frangible bridges, distributed along the periphery of the skirt and able to be broken during the first opening of the cap.
  • frangible bridges distributed along the periphery of the skirt and able to be broken during the first opening of the cap.
  • the weakening line formed by these bridges serves as a witness of this first opening, for the attention of users.
  • the nature of the removable connection between the upper skirt portion and the container neck is indifferent, so that the invention also aims, for example, the so-called “snap" caps, it that is to say the plugs able to be clipped around the neck, that the caps screwed.
  • the invention is more particularly concerned with plugs whose line of weakness is cut off, that is to say which comprises a succession of through-cuts, cut through the wall of the skirt and along its periphery, of to define, between two successive notches, one of the aforementioned frangible bridges.
  • Achieving the line of weakening by cutting rather than molding is preferred because it is more economical and more practical since it does not require the use of complex molds, provided for example with drawers.
  • the weakening lines obtained by cutting are traditionally provided to extend in a plane perpendicular to the longitudinal axis of the skirt, as proposed in EP-A-0 619 168 , which limits the possibilities of arrangements of the plugs, unlike plugs whose line of weakening is obtained by molding, such lines moldings that can include a portion of non-breakable material that permanently connects the removable skirt portion to the non-removable skirt portion, even when the cap is open.
  • the object of the present invention is to improve in a simple and economical manner the manufacture of cut-off line caps, to have a plug whose removable skirt portion remains connected to the non-removable skirt portion after the first opening of the cap.
  • the invention relates to a method of manufacturing a cap for a container neck, as defined in claim 1.
  • the weakening line is cut in the form of a helix, centered on the axis of the skirt and wound over more than 360 ° so that, in the direction of the axis of the skirt, the two peripheral ends of the line are arranged one above the other, delimiting between them a strand of material.
  • This strand is sized to form a non-breakable connection between the removable and non-removable skirt portions.
  • the invention also relates to a stopper for a container neck, as defined in claim 5.
  • This plug is preferably obtained by the process as defined above, with the structural advantages mentioned above.
  • the invention further relates to a machine for manufacturing a cap for a container neck, from a tubular skirt adapted to surround the neck and provided both with permanent retention means around the neck and removable fastening means to the neck, this machine being as defined in claim 9.
  • the machine according to the invention makes it possible to implement the method as defined above.
  • a plug 1 adapted to be removably attached to a neck 2 of a container.
  • the plug 1 considered here by way of illustration is a cap generally known as a “snap cap” or “Snap cap”, which is fixed by clipping on the neck 2.
  • the neck 2 is either integral with the rest of the container, especially when the latter is a glass or plastic bottle as shown on the figure 1 , or adapted to be permanently attached to a wall of the container, at an opening through this wall.
  • the plug 1 and the neck 2 have respective generally tubular shapes, whose central longitudinal axes are substantially merged, under the reference XX, when the cap is clipped on the neck.
  • the following description is oriented by considering that the terms “upper” and “top” correspond to a direction generally parallel to the axis XX and from the body of the container to its neck 2, that is to say say a direction directed to the upper part of all the figures except the figure 6 , while the terms “lower” and “lower” correspond to an opposite direction.
  • the neck 2 comprises a generally cylindrical body 4 with a circular base of axis XX. At its upper end, this body 4 defines a rim 3 at which the liquid in the container is intended to be poured. As shown in phantom only on the right side of the figure 4 on the outer face of the body 4, the neck 2 has, at its upper end, an edge 5 and, in its running part, a boss 6, this edge and this boss both extending radially outwardly from the body.
  • the plug 1, considered clipped on the neck 2 is open at its lower end and closed at its upper end by a bottom wall 10, at the outer periphery of which extends axially downwardly a tubular skirt 12 centered on the XX axis and circular base.
  • the cap here advantageously comprises a lip 14 which extends axially downwards from the bottom wall 10, centrally on the axis XX, inside the outer skirt 12.
  • the skirt 12 is provided with an outer tab 16, which extends radially outwardly projecting from a restricted peripheral portion of the skirt, subsequently considered as the front side of the cap 1, in the extent that this side is intended for service to be directed to the user.
  • the skirt 12 is internally provided with a clipping band 18 in the form of a bulge of material which, at the same time, extends radially towards the inside of the main wall of the skirt. and runs on the inner periphery of the skirt, here being interrupted on the front side of the cap.
  • This clipping band has, in longitudinal section of the cap, a convex surface, which is connected to the bottom wall 10 forming a receiving recess of the edge 5 of the neck 2.
  • the clipping of the plug is to engage this convex surface with the lower end of the edge 5, the latter then being received in the aforementioned recess, as shown only in the right part of the figure 4 .
  • the skirt 12 is adapted to separate into two distinct parts, namely an upper portion 12 1 , integral with the bottom wall 10, and a lower portion 12 2 initially connected to the part upper 12 1 at a weakening peripheral line 20 located axially in the current portion of the skirt.
  • the skirt portion 12 1 is intended to be completely disengaged from the neck 2, so that this portion 12 1 externally carries the tab 16 and internally the clipping strip 18.
  • the skirt portion 12 2 is, for its part, intended to remain around the neck 2.
  • this portion 12 2 is internally provided with a pallet 22 extending radially inwardly projecting from the inner surface of the skirt 12, running over the entire periphery of the skirt. When the cap is assembled at the neck 2, this pallet extends axially below the boss 6 and is adapted, when the cap is raised for the first time, to abut axially against this boss.
  • the weakening line 20 has peripheral notches 24, each of which passes radially right through the wall of the skirt 12. These cuts follow one another along the line 20, in other words, along the periphery of the skirt. Each pair of two notches immediately successive delimits, between the two notches of the pair, a frangible bridge 26 which connects, in the direction of the axis XX, the parts of skirts 12 1 and 12 2 .
  • the weakening line 20 is not inscribed in a plane perpendicular to the axis XX, but forms a helix, here circular, centered on this axis. Thus, projected in a longitudinal sectional plane of the skirt 12, the line 20 is inclined at an angle ⁇ relative to the perpendicular to the axis XX, as indicated in figure 4 .
  • the helical line 20 is wound on itself more strictly than 360 °, so that the peripheral ends of the line 20, respectively referenced 20A and 20B, are arranged one above the other. another in the direction of the XX axis, as clearly visible on the figure 3 .
  • the ends 20A and 20B delimit between them, in the direction of the axis XX, a strand of material 28 whose length L, that is to say its dimension along the periphery of the skirt 12, corresponds at the length of the axial overlap of the ends 20A and 20B.
  • This strand 28 forms a non-breakable connection between the skirt portions 12 1 and 12 2 : when the cap 1 is opened for the first time, the skirt portion 12 1 is disengaged from the neck 2, which breaks the bridges 26 of the line 20, without breaking the strand 28. In this way, a perennial connection is made between the skirt portions 12 1 and 12 2 , so that, to the extent that the portion 12 2 is retained permanently around the neck 2, the skirt portion 12 1 remains connected to the neck, via the strand 28, even when the cap 1 is open.
  • the strand 28 must have a breaking strength substantially greater than the breaking strength of the frangible bridges 26, this resistance of the strand 28 being dependent on its length L, its thickness which corresponds to the thickness radial of the wall of the skirt 12, and its axial width which corresponds to the pitch P of the helix formed by the line 20, and the material constituting the skirt.
  • the angle ⁇ is chosen equal to about 3 °, which induces a helical pitch P of about 1 mm.
  • the length L of the strand 28 is greater than 5 mm.
  • the ends 20A and 20B of the line 20 are free of bridges along the strand 28, the bridges 26 thus preferably being distributed substantially uniformly along the remainder of the line 20. way, during the first opening of the plug 1, all the bridges 26 are broken, which allows the ends 20A and 20B to open freely, that is to say that the edges of the notches 24 respectively constituting the ends 20A and 20B can move freely from each other, and thus allow the strand 28 to be deployed over its entire length L with respect to the skirt portions 12 1 and 12 2 .
  • the strand 28 is located substantially diametrically opposite the tab 16. In this way, the presence of the strand 28 does not induce any discomfort to unclip the skirt portion 12 1 causing this part by tilting around a geometrical axis orthoradial to the axis XX and located on the rear side of the skirt 12, by digital biasing of the tab 16.
  • the skirt 12 is initially disposed at the same time closed by the bottom wall 10 and provided with the lip 14, the tab 16 and the clipping band 18. This skirt is obtained in particular by molding a plastics material .
  • the head 104 is then introduced into the interior of the skirt 12, by interposing axially between this head and the bottom wall 10, a resilient compression plunger 116, so that this pusher keeps the bottom wall 10 pressed against the surface. 108 of the support plate 106, with the axis XX perpendicular to this surface. By radially shifting the axis 102 relative to the axis X-X, the head 104 presses the skirt 12 against the cutting edge 112 of the plate 110, in a direction substantially radial to the axis X-X.
  • the mandrel 100 is then rotated on itself about its axis 102, as indicated by the arrow 120 at the figure 6 , so as to roll the skirt 12 against the edge 112 of the blade 110, as indicated by the arrow 122, the skirt then describing, taken as a whole, the path 124 along the edge 112.
  • This edge cuts the wall of the skirt 12 from one side to the other and thus forms the notches 24, while, at the passage of each notch 114 of the blade 110, the wall of the skirt is not cut, thus forming the bridges 26.
  • the head 104 is provided with a peripheral groove 118, which receives the end of the cutting edge 112 when the latter passes right through the wall of the skirt.
  • the bottom wall 10 slides against the support plate 106, being held in abutment against the surface 108 by the pusher 116.
  • This surface 108 is not rigorously parallel to the blade 110, but is instead inclined with respect thereto, at an angle ⁇ noted at figure 7 , in the direction of the trajectory 124.
  • the blade 110 does not cut the skirt 12 in a plane strictly perpendicular to the axis XX, but cuts the skirt along a helical path to form the weakening line 20 such as as described above with regard to Figures 2 to 4 .
  • the position of this skirt, along its axis XX, is modified relative to the blade 110, following a translation T both parallel to the axis XX and directed in one direction, as shown on the figure 7 .
  • the skirt 12 translates progressively relative to the blade 110 during their relative rotational drive, because of the continuous inclination of the surface 108, the angle of inclination ⁇ of this surface thus corresponding to the angle ⁇ relative to the helical shape of the line 20.
  • the relative rotational drive between the skirt 12 and the blade 110 is made on a total angular travel strictly greater than 360 °. In practice, this stroke is preferably greater than 375 °, in order to obtain a length L sufficient for the strand 28.
  • the pitch P of the helical shape of the line 20 is greater than or equal to 1 mm, it is expected that the skirt 12 is translated at least 0.5 mm from the blade 110 while the skirt is exactly a turn on itself.
  • FIG. 8 and 9 an alternative embodiment of the machine of Figures 5 to 7 , making it possible to manufacture the plug 1.
  • This alternative embodiment comprises the same components, namely the mandrel 100, the support plate 106, the cutting blade 110 and the pusher 116. It is different from the embodiment of the Figures 5 to 7 in that the surface 108 of the plate 106 extends perpendicularly to the axis 102 of the mandrel 100.
  • the blade 110 is here inclined with respect to the surface 108 along the direction of the trajectory 124, at an angle noted ⁇ on the figure 9 .
