Definitions

  • the invention relates to the field of neck containers and their caps, provided with a tamper-evident closure element.
  • the threaded neck of the flexible tube is extended by a blind tube also threaded connected to the end of the neck by a weakened area of reduced diameter, and during screwing of the capsule which has complementary threads of the threads of the neck and of the blind tube which extends it, the capsule first abuts on the end of the thread of the blind tube and it suffices to force the screwing to break the weakened zone.
  • the subject of the invention is a device for closing a neck container which, like the device described in document EP-A-0 001 959, is provided with a cap with internal reliefs, said neck carrying a dispensing orifice. surmounted by a tamper-evident seal in one-piece plastic material with the neck, seal whose base is connected by a tear-off zone at the edge of the orifice of said neck and whose head carries external reliefs penetrating into the internal reliefs of the cap, the cooperation of the external reliefs of the cover and of the internal reliefs of the cap allowing the rupture of the cover by rotation of the cap.
  • the depressed cap generally hides the tamper-evident seal.
  • the cap may have an outside diameter close to the diameter of the body of the container or slightly smaller than this diameter, so that it cannot descend lower than the shoulder of the container.
  • the cooperation of the reliefs of the head of the cover and of the key of the cap is obtained in a different and simpler way than in the device described by document EP-A-0 001 959: the reliefs of the head of the cover fit axially into the internal crown with internal reliefs or "cap key", then causing the centering of the cap and preventing it from rotating relative to the cover and the container.
  • the longitudinal reliefs of the head of the cover, the head which then constitutes the male key of the opening device or "tube key” ', and the reliefs of the "cap key” must therefore be complementary, that is to say ie nestable, but since they are preferably obtained by molding, they can have very varied shapes.
  • the reliefs of the key of the tube are streaks and the key of the cap is constituted by a crown comprising internal ribs fitting into said streaks, either smoothly - the broken seal detaching from the cap - or force - the cover then remaining integral with the cap or more precisely trapped in the key of the cap.
  • the internal crown with internal reliefs of the cap is extended by a skirt with an inside diameter close to the outside diameter of the neck of the container, so that this skirt can be engaged on the neck when the cap is put in place for the storage and presentation of the container, so also that it can be engaged more fully on the neck once the lid broken and detached.
  • This cap skirt is then a means of centering the cap on the neck of the container, completing the centering of this cap by fitting the "key of the tube” into the "key of the cap", and coming to relay it from the broken tamper evident seal.
  • the base of the tamper-evident seal comprises means for sealing the container after rupture of said seal.
  • these sealed closing means include a collar and a skirt, the lower lips of which are slightly conical so as to engage in the orifice of the neck when the container is closed.
  • the tamper-evident seal then becomes, after rupture, a sealing seal.
  • the reliefs of the head of the cover and the reliefs of the key of the cap are preferably adjusted so that the head of the 'operculum is forced into the key of the cap and thus the lid remains secured to the cap after it breaks.
  • the cap then carries the sealing means and, after the first opening, the sealed closure of the container is greatly facilitated.
  • a neck container provided with a cap according to the invention
  • the neck being surmounted by a tamper-evident seal whose base is tearable and whose head comprises reliefs and hood comprising a key, the fitting of which on said reliefs allows the rupture of the cover by the rotation of the cap
  • the base of the tamper-evident seal also optionally comprising means for sealing the container after rupture of said cover
  • the neck of the container and the cap comprise complementary screwing means allowing the screwing of the cap for closing the container after rupture of the tamper-evident seal.
  • the neck of the container then carries an external thread and the cap screwing means consists in particular of a complementary thread carried by an intermediate ring between the outer skirt and the key of the cap.
  • screwing means allow for example the tightening of the sealing means possibly present at the base of the tamper-evident seal preferably remained secured to the cap after it has broken.
  • the skirt of the tamper-evident seal is screwed and permanently fixed on the outside thread of the neck.
  • the necked container may for example be made of plastic or of a metalloplastic complex, of painted metal, of bare or coated glass, of porcelain or ceramic, and the fixing of the lid with an internally threaded skirt at its base can be made typically. by welding, gluing, by clip, by snap-fastening or by local deformation.
  • the skirt of the cover has a tear-off zone directly above the edge of the orifice.
  • the ruptured lid may comprise at its base means for sealing the container, constituted as above by a collar and by the ruptured skirt.
  • the exterior of the part of the skirt screwed and permanently fixed to the neck may itself include an external thread complementary to a means for screwing the cap.
  • a closure device for a necked container provided with a cap comprising a tamper-evident seal surmounting the neck of the container, a seal whose head has reliefs on its periphery, and whose cap comprises a key, the fitting of which on said reliefs allows the rupture of the cover by the rotation of the cap
  • this device is characterized in that the base of the cover consists of a flared skirt whose end is connected by injection obliquely at the edge of the neck opening.
  • the oblique arrangement of the circumference of the flared skirt of the base of the cover has the effect that, after rupture along the zone of weakness formed by the connection of the skirt with the edge of the orifice and possibly with some points from the inside surface of the neck, the base of the seal can be pushed into the orifice when filling with the broken seal.
  • the flared skirt of the cover is an interesting sealing solution for storage, especially when the diameter of the orifice is relatively large and between 5 and 15 mm.
  • the oblique injection precision of the flared skirt is then less critical than the injection precision of the lower lip of the cover in a direction substantially parallel to the axis of the orifice of the neck.
  • the cover can be used for filling, in association or not with the cap, its base can then be pressed into the orifice, even if the outline of the broken end slightly exceeds the contour of the orifice, this thin end, for example 0.2 to 0.4 mm, being flexible like the lip of a seal. This filling thus provides a seal or a good semi-seal for intermediate storage.
  • the end of the flared skirt of the cover is likewise connected by injection at an oblique angle to the edge of the orifice of the neck.
  • This end of the skirt of the cover consists firstly of parts welded to the edge of the raised parts of the contour of the orifice of the neck, at the meeting of the injection cone and the edge of the orifice , and on the other hand by webs of thermoplastic material which continue the welded parts and penetrate obliquely inside the hollow parts of the outline of the orifice. The veils injected obliquely penetrate into the hollow parts of the orifice.
  • the end points of these webs penetrating obliquely into the hollow parts are either very close to the internal wall of the neck, or often discreetly or discontinuously welded to this internal wall.
  • the end of the flared skirt injected obliquely provides an improved semi-sealed obturation of the hollow parts of the orifice, this obturation is in fact much more complete than that obtained with a lower lip injected in a direction substantially parallel to the axis of the orifice.
  • Such an improvement is usually obtained with injection directions making angles of 30 ° to 80 °, and preferably from 45 ° to 75 °, with the axis of the orifice.
  • the end of the flared skirt of the cover constitutes a zone of weakness of discontinuous resistance, its welding at the neck being ensured and having a marked mechanical resistance only on the edge of the raised parts of the contour of the neck opening, and the rupture of the cover is facilitated.
  • the end of the flared skirt of the cover can be pushed into the orifice, the outline of the end of the broken cover being substantially complementary to the outline of the orifice and the flexibility of the broken end allowing the seal to be inserted into the orifice, even if the two contours are disoriented relative to each other, the outside of the ruptured portion of the seal then locally protruding from the reliefs the outline of the hole.
  • the partial bending of the end of the flared skirt during the insertion of the cover into the orifice of the neck contributes to the holding of this semi-sealed filling means which constitutes the broken cover.
  • the base of the cover is thus constituted by a flared skirt, the end of which is connected to the edge of the orifice of the neck, the head of the cover which has reliefs on its periphery and the crown of the key of the cap. that fits this head usually have smaller outside diameters than the outside diameter of the neck.
  • An intermediate crown with an internal diameter close to the external diameter of the neck of the container is then preferably present inside the cap, this intermediate crown being able to be engaged on the neck when the cap is put in place for the storage and presentation of the container, and which can then be engaged more fully on the neck once the seal has been broken and either detached, or pressed in for the semi-sealed filling.
  • the reliefs of the head of the cover and those of the key of the cap preferably fit together forcefully, so that the cover remains prisoner of the hood key once the end of her flared skirt is broken.
  • the alignment of the cover is then fixed relative to the cap, the semi-sealed filling of the container is easily obtained by the establishment and the insertion of the cap on the neck.
  • the stopping position of the insertion of the cover in the key of the cap can be conditioned either by the end of the injection core of the cover, which end then abuts in the bottom of the cap, either by the length of the skirt extending the crown of the key of the cap, skirt which then abuts on the flared skirt of the cover.
  • the quality of this semi-sealed filling is further improved by a particular structure of the cap, in which the crown of the key of the cap comprises a skirt of outside diameter. less than or approximately equal to the smallest inside diameter of the neck orifice, i.e. the diameter corresponding to the raised parts of the outline of this orifice, so that this skirt of the crown of the key of the cap penetrates in the hole following the end of the seal broken during the filling.
  • the stop position of the cap is then adjusted either by the length of the intermediate crown, or by the length of the outer skirt of the cap, or even by the length of the intermediate crown abutting on the shoulder of the container at the base. bottleneck.
  • the device of the invention may also comprise, particularly in the case where the orifice of the neck is circular or else has sinuosities of shallow depth and preferably less than 1 mm, means complementary screwing of the neck of the container and the cap, allowing a screwed closure during recapping.
  • the screwing means of the cap is then preferably a thread carried by an intermediate crown coming to engage on the neck during the positioning of the cap for the storage and the presentation of the container, and being able to engage more fully and be screwed onto the neck once the seal has been broken, so as to better ensure the closure in the semi-sealed filling of the container.
  • FIG. 1 shows in longitudinal axial half-section a first example of a closure device according to the invention, in which the orifice of the neck is circular, the cap being in the process of being inserted.
  • Figure 2 shows in longitudinal axial half-section a second example of a closure device according to the invention, in which the orifice of the neck is fancy, the cap being pressed.

  • the second example differs from the first example only in the presence of a fancy orifice (13) on the neck (1) ( Figure 2).
  • This fancy orifice (13) can have a variable shape
  • Figure 3 gives an example.
  • the crown of the injection points (14) corresponds substantially to the internal vertices (15) of the sinuosities of the contour of the orifice so that the connection of the lower end (3) of the skirt of the the cover (4) has better resistance and tightness at the location of the tops (15) than between these tops where the web of thermoplastic material may be less solid and not completely waterproof.

  • the key of the cap (11) is thus held more firmly on the head of the cover constituting the key of the tube (6), which facilitates the opening of the container by rotation of the cap (8).
  • This opening is obtained by rotating the cap in one direction or the other, for example for an angle of rotation between 30 ° and 60 °.

  • the cap (8) also comprises an intermediate crown (18) carrying at the end an internal thread (19). When the cap (8) is pushed in, the end of this intermediate ring (18) sinks onto the outside of the neck, the thread (19) being hollow and the end (20) of the ring (18) being thinned.
  • This intermediate ring (18) is thus at this stage a means of centering the cap (8), which by holding the cap more firmly on the key of the tube (6) facilitates the opening of the container by rotation of the cap (8).
  • the sealing means (3) and (17) thus play the role of lip seal and they are used in the closure device of the invention, whether or not there are screwing means, that the closure of the container after rupture of the tamper-evident seal is done by simple pressing or with screwing.
