Definitions

  • the invention relates to a flat drink cap to be fixed by hooking onto a container neck, in particular on a flat drink bottle neck, and to a set consisting of a cap and a container neck.
  • Container caps provided with a bottom and a threaded outer skirt which is screwed onto a complementary thread of the neck of the container are well known in the state of the art. It can be seen that this type of fastening by screwing imposes a height of the neck and the skirt of the cap important to accommodate the threads, resulting in a large footprint in height. In addition, the threads require a large amount of material.
  • a plastic capsule for capping a container having a non-threaded neck provided with an upper flange and a lower flange.
  • the cap has a flat bottom, and an outer skirt having an upper portion secured to the bottom and a lower tamper ring to remain in place on the neck of the container, trapped under the lower flange.
  • the ring is connected to the skirt by four welds, a hinge and two tabs which are welded to the circumference of the skirt and the ring and serve as tamper evidence.
  • the sealing of the capsule is provided by an inner skirt provided with a bead protruding radially towards the outer skirt and defining with the outer skirt an annular groove in which is inserted the rim of the neck of the container.
  • the upper element the outer skirt has a protuberance to ensure a snap under the upper collar of the neck.
  • This capsule is of complex structure, and its manufacture requires many operations, including welding legs for tamper evidence. It is therefore not suitable for high speed manufacturing and low cost.
  • germs can be introduced into the gap between the solder points and back to the neck, so that the storage of containers can be problematic.
  • the bead of attachment to the flange which in theory could constitute a barrier against the rise of germs, is in fact inefficient because the relative positioning between the bead and the flange is not controlled.
  • the invention therefore aims to overcome the disadvantages of the state of the art, so as to provide a cap of reduced size and having a good seal and good performance on the aseptic plane.
  • the subject of the invention is a cap to be fixed by hooking on a container neck, comprising: a bottom wall; an outer skirt defining a reference geometric axis Z, the outer skirt having: a proximal portion secured to the bottom wall and having a threadless inner face provided with at least one inner hooking protuberance, and a tamper-evident ring distal located in the extension of the proximal portion of the outer skirt and connected to the proximal portion of the outer skirt by a breakable junction; the plug further having a radially inner skirt integral with the bottom wall and forming a first elastically deformable sealing lip, the proximal portion of the outer skirt further comprising a second lip located between the inner hooking protrusion and the tamper-evident ring, the second lip projecting radially inwards and axially towards the tamper-evident ring.
  • the absence of threading reduces the height of the skirt, so the size of the cap, and its thickness, so the amount of material.
  • the second lip provides a barrier against the intrusion of germs. Because of its orientation and its elasticity, it also acts as a return spring when it bears against the neck of the container, which contributes to the protrusion of attachment against the relief of the container on which the protrusion comes hang on.
  • the inner skirt integral with the bottom wall delimits with the inner face of the proximal portion of the outer skirt and the bottom wall an annular groove partially closed by the inner hooking protuberance.
  • the annular groove makes it possible to receive the rim of the neck of the receptacle, the inner skirt contributing both to the positioning of the stopper during assembly and to the sealing of the stopper.
  • the inner skirt is preferably provided with a bead projecting radially towards the outer skirt.
  • the second lip is substantially frustoconical.
  • the plug may have axial symmetry, which simplifies both its manufacture and its assembly.
  • the breakable junction is constituted by breakable bridges which can be separated from each other by incisions with contiguous edges.
  • the incisions practiced constitute an additional effective barrier against germs or other pollutants.
  • the incisions are through, which allows to fully control the force required to tear the bridges during the first opening.
  • the cap may further comprise a gripping tab projecting radially outwardly from the proximal portion of the skirt or the bottom wall.
  • This assembly offers, compared to devices with neck and threaded cap, a significant material gain, both at the neck and the cap, with high aseptic performance.
  • the neck further comprises an additional flange, the retaining collar being between the attachment flange and the additional flange, the tamper evident ring being located between the retaining flange and the additional flange.
  • the tamper ring falls on the additional collar.
  • FIG. figure 1 is a sectional view of a plug according to an embodiment of the invention.
  • the one-piece plug of molded plastic material 1, mounted on a container neck 2, comprises a bottom 3 consisting of a substantially discoidal wall, a substantially cylindrical outer skirt 4 and an inner sealing skirt 5, the two skirts 4 and 5 defining a common axis of revolution ZZ.
  • the stopper 1 is more particularly adapted to a threadless container neck as shown in the figures, which has on its outer face and from its base to its upper flange 21: a lower flange 22, an intermediate flange 23 for retaining and a upper flange 24 hanging part of the upper flange 21, the three collar 22, 23 and 24 protruding radially outwardly.
  • the neck further has a cylindrical inner face 25 defining the opening of the container.
  • the outer skirt 4 of the cap 1 has a proximal portion 41 directly integral with the bottom, and a distal portion 42 constituting a tamper-evident ring.
  • the proximal portion 41 has an inner face 410 provided with one or more hook protuberances 411 projecting radially inward, and more specifically in the exemplary embodiment, a single annular protuberance 411.
  • the distal portion 42 of the skirt located in the extension of the proximal portion 41, in continuity therewith, also has one or more protuberances 420 projecting radially inwardly.
  • At the junction between the distal portion and the proximal portion of the skirt are made incisions 43 passing through the wall of the skirt 4.
  • Each incision 43 has contiguous flanges, which is due to the fact that the incisions 43 are obtained by a cut made in the wall of the skirt without removing material.
  • the incisions 43 are made all around the skirt, and separated from each other by breakable bridges 44.
  • the inner skirt 5 is of variable thickness and slightly flared shape of its base secured to the bottom 3 towards its free end. More specifically, the thickness of the inner skirt 5 is relatively low at its base, which gives it a certain elasticity, while it is greater near its free end, forming a sealing bead 51 protruding therefrom radially outward.
  • An annular space 52 is delimited between the inner skirt 5, the proximal portion 41 of the outer skirt and the bottom 3 of the cap, forming a groove 52 partially closed by the protuberance 411.
  • the proximal portion 41 of the outer skirt 4 is provided on its inner face 410 with an elastic lip 412 protruding radially inwards and axially towards the tamper-evident ring 42 so as to bear against a frustoconical face 230 of the intermediate collar 23.
  • the cap is mounted on the neck of the container in force.
  • the upper flange 21 of the neck of the container is housed in the groove 52 and the hooking protrusion 411, after being deformed to ensure the passage of the upper flange 24, engages with the upper flange 24 to ensure the hooking of the cap on the neck of the container.
  • the inner skirt 5 by its flexibility, is deformed and is pressed, at the bead 51, on the cylindrical inner face of the neck of the container, ensuring at this level the tightness of the closure.
  • the elastic lip 412 is slightly deformed, resting on the intermediate collar 23. This contact is a first barrier against the intrusion of germs or pollutants.
  • the interference between the attachment protuberance 411 and the upper collar 24 provides a second barrier to secondary and optional germs.
  • the lip 412 by its elastic deformation, moreover tends to push the entire plug upwards so that the hooking protrusion 411 is held in abutment against the collar 24 with a pressure determined by the deformation of the lip 412. Furthermore, the contact obtained between the lip constituted by the inner skirt 5 and the cylindrical inner face 25 of the neck provides the main seal.
  • the container is opened by pulling on the stopper 1 or by pressing the thumb from below the toothed flange 6 upwards.
  • the protuberances 420 of the tamperproof ring 42 are locked in abutment against the intermediate flange 23, which which causes the breaking of the breakable bridges 44 during the upward movement of the upper part of the plug.
  • the ring 42 then falls on the lower flange 22, away from its initial position. If the cap 1 is reapposed on the container, the ring 42 disengaged from the proximal portion 41 of the skirt remains at a distance therefrom, thus marking the opening.
  • the closing and opening of the container is therefore carried out without rotation of the cap about its axis Z, therefore without screwing.
  • the cap has no threading, but can optionally be mounted on a threaded neck, provided that the neck is provided with an upper collar and an intermediate collar and that the thread does not interfere with the inner face 410 without threading the outer skirt 4.
