Definitions

  • Patent application EP-A-0 119 145 of the applicant describes a container with a plastic neck, the neck being surmounted by a tamper-evident seal whose base is tearable and whose head comprising reliefs fits into a key with internal reliefs of the cap, a key whose cooperation with said reliefs of the head of the cover allows the rupture of this cover by the rotation of the cover.
  • the casing can be done by force, the cover then remaining trapped in the key of the cap after its rupture.
  • the centering of the cap and therefore of the key when the cap is pressed onto the neck is made easier by the presence in the cap of a crown fitting the neck with little play.
  • This centering crown can be the crown of the key of the cap itself when the cover is roughly the same diameter as the orifice of the neck, or else a separate crown when the cover has a smaller diameter because it is connected to the edges of the orifice of the neck by a flared skirt injected obliquely.
  • the base of the ruptured seal may include means for sealing the orifice of the neck, and that the cap and the neck may carry screwing means. complementary cooperating for recapping after rupture of the cover.
  • the container of the invention is a plastic container provided with a cap also made of plastic, the neck being surmounted by a tear-off sealing cap at its base and the cap comprising a relief key. interiors. This key fits the lid when the cap covers the neck, and the rotation of the cap then allows the rupture of the lid.
  • the invention can be applied to any form of cover accompanied by a shape of all the edges of the internal reliefs of the key of the cap ensuring a certain tightening during the fitting of the cover by this key.
  • the cover preferably has a lateral surface of revolution around its axis of symmetry which is usually that of the neck it covers.
  • the operculum for example, has a frustoconical or parabolic surface.
  • the cover comprises a circular cylindrical lateral surface.
  • the "tightening" obtained is preferably between 0.4 and 0.9 mm in diameter, and more preferably between 0.5 and 0.7 mm in diameter, this at least over a certain height, typically over at least 2 mm.
  • the successive circles perpendicular to the common axis of the cover and of the cap key and passing through the ends of the tapered edges of the interior reliefs of the key of the cap have for this purpose diameters less than 0.4 to 0.9 mm, and preferably 0.5 to 0.7 mm, than the diameters of the lateral surface of the cover which correspond to them.
  • the tapered edges of the reliefs of the key of the cap are cutting, under the fitting conditions with tightening indicated above, for the lateral surface of the cover which is made of less hard plastic. Their cutting power comes in for the ease of fitting together as well as for the quality of the streak or notch obtained which conditions the effectiveness of the drive of the cover by rotation of the cap.
  • the surfaces of the reliefs involved in the rotation drive are generally limited to narrow areas where there is contact.
  • the small portions of tapered edges inserted into the plastic material of the cover intervene through all of their surfaces for the drive in rotation of the cover by the rotation of the cap.
  • the end angle of these edges tapered is preferably between 7 and 20 ° and more preferably between 10 and 16 °.
  • These conditions can be associated with one or the other of the preferential conditions of nesting with tightening, but it is recommended to have at least at the same time a “tightening” of 0.4 to 0.9 mm in diameter and angles of extremities of the tapered edges between 7 and 20 °.
  • the internal reliefs of the key of the cap are carried by a crown, the end of which easily fits on the cover, and these internal reliefs gradually widen from their lower end, so that the beginning of the insertion of the cap ensures good centering of the key on the cover and that the beginning of the striation of the lateral surface of this cover by the tapered edges of the interior reliefs of the key consists of a progressive cutting of the upper part of this lateral surface.
  • the progressive widening of the interior reliefs of the key of the cap is preferably carried out over a height at least equal to 2 times the maximum width of said reliefs.
  • the ends of the tapered edges of the lower reliefs of the cap key are located, at least over a certain height - in practice at least over 1.5 to 2 mm - on successive circles perpendicular to the axis of the cap. der diameters 0.4 to 0.9 mm smaller than the corresponding diameters of the cover, and said tapered edges have, in section perpendicular to the same axis, an end angle of between 7 and 20 °.
  • the container (1) shown in FIG. 1 comprises a skirt (2) with an external diameter of 33 mm in polyethylene surmounted by an overmolded head (3) 0.8 to 1.2 mm thick in low density polyethylene, head ( 3) itself comprising above its shoulder (4) a neck (5) with an outside diameter of 17 mm and a height of 12 mm carrying a fancy orifice (6) with 6 recesses (7) separated by 6 raised parts (8), this orifice (6) having a hollow diameter of 14 mm.
  • a tamper-evident seal (9) which comprises at its base a flared skirt (10), then above a circular cylindrical lateral surface (11) of diameter ( ⁇ D ) equal to 7.5 mm and 6 mm high, then finally an end forming a cover (111) 2 mm high.
  • the cap (12) of the container being inserted is made of polypropylene, it has an outside diameter of 32 mm and a height of 26 mm. Inside it carries an intermediate crown (13) with an internal diameter of 17.5 mm and a height of 20 mm intended to fit the neck (5), and a circular central crown of height 9 mm (14) bearing on its inner cylindrical surface (15) of diameter 8.0 mm 12 raised ribs (16) in the form of tapered fins.
  • tapered fins (16) visible in section perpendicular to the longitudinal axis (L) in Figure 2 have, according to this section, an end angle (a) of 15 °. Their width in the radial direction, constant for all the fins, is 0.55 mm.
  • the diameter (0 d ) of the circle perpendicular to the axis (L) passing through the ends (17) of the tapered fins (16) of the key (14+ 16) of the cap (12) is 6.9 mm at level of this cut, and this diameter remains constant over 6 to 7 mm in height.
  • FIG. 3 shows more clearly the beginning of the engagement of the cap key (14 + 16) on the cover (9).
  • the end portion (18) of the crown (14) of the key of the cap is about 1 mm free of reliefs in the form of tapered fins (16).
  • the reliefs of the fins (16) then begin by gradually widening from 0 to 0.55 mm by 1.5 mm. Thanks to the end portion (18) of the crown (14) free of reliefs and thanks to the progressive widening (19) of the reliefs of the fins (16), the engagement of the key of the cap (14 + 16) is in all cases easy and progressive and will ensure good centering for the start of the stripping of the cover (9) for the fins (16).
  • the opening method of the invention is effective, despite apparent differences in length between the fine streaks caused by the various sharpened fins. We also see that these streaks appear finer than the portions of fins which have notched the lateral wall of the lids, which undoubtedly means that these portions of fins were inserted with elastic tightening of the portion of the plastic material of the lid walls thus striated.
  • the device and the opening method of the invention most often applies to tubular containers having a circular orifice with a diameter between 5 and 15 mm, or even a fancy orifice having an injection circle with a diameter included between 5 and 15 mm.
  • the thicknesses of the welded areas of weakness are generally between 0.1 and 0.4 mm.
  • tubular containers are typically provided with a cap with a diameter between 25 and 40 mm and, as described by EP-A-0 119 145, the opening torque by breaking the tamper-evident seal is then typically between 10 and 90 Nm, and between 10 and 30 Nm in the case of fancy orifices surmounted by welded seals discontinuously.
  • the device and method of the invention are used essentially in the field of food products for liquids, syrups, creams, products in a pasty state or in the form of gums, and for products in a divided state; in the field of pharmaceutical, hygienic or cosmetic products; in all previous presentations or consistencies, and in the area of chemicals or maintenance.
