Definitions
- the invention relates to the field of neck containers and their caps, provided with a tamper-evident closure element.
- 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 cap allows the rupture of this cap by the rotation of the cap.
- 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 key interior reliefs. 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 of the tapered 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 cover has for example 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 preferably still 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 nesting conditions with tightening indicated above, for the lateral surface of the cover which is made of less hard plastic. Their cutting power intervenes for the ease of fitting together as well as for the quality of the streak or notch obtained which conditions the efficiency of the drive of the cover by rotation of the cap.
- the relief surfaces 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 ends of 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 gradual notching 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 internal reliefs of the cap key are located, at least over a certain height - in practice at least 1.5 to 2 mm - on successive circles perpendicular to the axis of the cap. diameters 0.4 to 0.9 mm lower than the corresponding diameters of the cover, and said tapered edges have. in section perpendicular to the same axis. an end angle 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) comprising itself 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 (P 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 (") of 15 °. Their width in the radial direction, constant for all the fins, is 0.55 mm.
- the diameter (b 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.
- the circles of diameter ( ⁇ d ) of this key are therefore 7.5-6.9 - 0.6 mm less than the diameter ( ⁇ D ) of the cylindrical lateral surface of the cover (9).
- 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 cap (12) can be pushed onto the cover (9) then removed and repeated this maneuver more than ten times without observing any difficulties, and that the rupture of the cover (9) was then easily obtained by rotation of the cap (12), as described above.
- the caps (12) After removing the caps (12), it was observed by eye that the lateral surfaces (11) of the lids (9) had fine, more or less apparent streaks, starting at the high end (21) of these surfaces lateral (11) and descending on 2 to 4 mm, the spacing of these streaks or stripes corresponding to the spacing of the fins (16).
- the opening method of the invention is effective, despite apparent differences in length between the fine streaks caused by the various tapered fins. We also see that these streaks appear finer than the portions of fins which have cut the lateral wall of the lids, which undoubtedly means that these portions of fins were inserted with elastic tightening on the part 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.

Abstract
Description
L'invention concerne le domaine des récipients à goulot et de leurs capuchons, munis d'un élément de fermeture inviolable.The invention relates to the field of neck containers and their caps, provided with a tamper-evident closure element.
La demande de brevet EP-A-0 119 145 de la demanderesse décrit un récipient à goulot en matière plastique, le goulot étant surmonté d'un opercule d'inviolabilité dont la base est déchirable et dont la tête comportant des reliefs s'emboîte dans une clef à reliefs intérieurs du capuchon, clef dont la coopération avec lesdits reliefs de la tête de l'opercule permet la rupture de cet opercule par la rotation du capuchon. L'emboîtage peut se faire en force, l'opercule restant alors prisonnier de la clef du capuchon après sa rupture. Le centrage du capuchon et donc de la clef lors de l'enfoncement du capuchon sur le goulot est rendu plus facile par la présence dans le capuchon d'une couronne emboîtant le goulot avec un faible jeu. Cette couronne de centrage peut être la couronne de la clef du capuchon elle-même lorsque l'opercule est à peu près de même diamètre que l'orifice du goulot, ou bien une couronne distincte lorsque l'opercule a un diamètre plus faible parce que se raccordant aux bords de l'orifice du goulot par une jupe évasée injectée en oblique.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 cap allows the rupture of this cap by the rotation of the cap. 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.
Parmi les différentes dispositions décrites par le document ci-dessus, on note encore que la base de l'opercule rompu peut comporter des moyens de fermeture étanche de l'orifice du goulot, et que le capuchon et le goulot peuvent porter des moyens de vissage complémentaires coopérant pour les rebouchages après rupture de l'opercule.Among the various arrangements described by the above document, it should also be noted that 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.
La solution décrite par le document EP-A- 0 119 145 ainsi que ses différentes variantes d'exécution répondent aux problèmes de la facilité d'ouverture de récipients à goulots surmonté d'un opercule d'inviolabilité et de leur rebouchage ultérieur éventuel, mais présente les contraintes suivantes :
- - la surface latérale de l'opercule doit présenter des reliefs s'emboîtant dans les reliefs de la clef du capuchon.
- - les nombres des reliefs de l'opercule et de la clef du capuchon doivent être suffisants, et leurs profils étudiés, pour qu'il n'y ait pas de problème sensible d'indexage lors de l'emboîtement de l'opercule par la clef du capuchon qui doit se produire lorsqu'on met en place le capuchon sur le goulot.
- - The lateral surface of the cover must have reliefs fitting into the reliefs of the key of the cap.
- - the numbers of the reliefs of the cover and of the key of the cap must be sufficient, and their profiles studied, so that there is no significant problem of indexing during the nesting of the cover by the key of the cap which must occur when the cap is placed on the neck.
Ces particularités entraînent toutes deux des complications au niveau de l'outillage de fabrication, et les reliefs de la surface latérale de l'opercule peuvent avoir d'autres inconvénients, concernant par exemple la manipulation et/ou l'esthétique.These features both lead to complications in the manufacturing tool, and the reliefs of the lateral surface of the cover may have other drawbacks, for example concerning handling and / or aesthetics.
La demanderesse a recherché une solution différente, permettant d'éviter les complications et inconvénients précédents.The Applicant has sought a different solution, making it possible to avoid the preceding complications and disadvantages.
Comme il est connu, le récipient de l'invention est un récipient en matière plastique muni d'un capuchon également en matière plastique, le goulot étant surmonté d'un opercule d'étanchéité déchirable à sa base, et le capuchon comportant une clef à reliefs intérieurs. Cette clef emboîte l'opercule lorsque le capuchon coiffe le goulot, et la rotation du capuchon permet alors la rupture de l'opercule.As is known, 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 key interior reliefs. This key fits the lid when the cap covers the neck, and the rotation of the cap then allows the rupture of the lid.
De façon nouveile, l'opercule d'étanchéité a une surface latérale lisse (moyen a)) et, de façon surprenante, on obtient la rupture de l'opercule par rotation du capuchon enfoncé sur le goulot grâce aux trois moyens supplémentaires suivants:
- b) la matière plastique de la clef du capuchon est plus dure que la matière piastique de l'opercule;
- c) les reliefs intérieurs de la clef du capuchon se terminent par des arêtes effilées:
- d) au moins sur une certaine hauteur, les cercles successifs, perpendiculaires à l'axe commun du récipient et du capuchon et passant par les extrémités des arêtes effilées des reliefs de la clef du capuchon, ont des diamètres plus faibles que les diamètres de la surface latérale de l'opercule qui leur correspondent, lors de l'emboîtement de l'opercule par la clef du capuchon.
- b) the plastic material of the cap key is harder than the plastic material of the cover;
- c) the interior reliefs of the cap key end with tapered edges:
- d) at least over a certain height, the successive circles, perpendicular to the common axis of the container and of the cap and passing through the ends of the tapered edges of the reliefs of the key of the cap, have diameters smaller than the diameters of the lateral surface of the lid which correspond to them, during the fitting of the lid by the key of the cap.
On a alors un emboîtement avec serrage de l'opercule par les reliefs à arêtes effilées de la clef du capuchon, et on constate que ces arêtes effilées strient l'opercule en matière plastique moins dure. Après rupture de l'opercule, celui-ci reste prisonnier de la clef du capuchon.There is then an interlocking with tightening of the cover by the reliefs with tapered edges of the key of the cap, and it is found that these tapered edges strip the cover in less hard plastic. After rupture of the cover, it remains trapped in the key of the cap.
Le problème de l'indexation pour obtenir l'emboîtement disparaît complètement dans le cas des opercules à section(s) circulaire(s). La fabrication est simplifiée pour l'opercule dont la surface latérale est lisse.The problem of indexing to obtain nesting disappears completely in the case of lids with circular section (s). The manufacturing is simplified for the cover, the lateral surface of which is smooth.
L'invention peut d'appliquer à toute forme d'opercule accompgnée d'une forme de l'ensemble des arêtes effilées des reliefs intérieurs de la clef du capuchon assurant un certain serrage lors de l'emboîtement de l'opercule par cette clef. De façon à avoir la facilité d'un emboîtement isotrope, l'opercule a de préférence une surface latérale de révolution autour de son axe de symétrie qui est habituellement celui du goulot qu'il coiffe. L'opercule a par exemple une surface tronconique ou parabolique. De façon habituelle, et c'est le cas pour les exemples qui suivent, l'opercule comporte une surface latérale cylindrique circulaire.The invention can be applied to any form of cover accompanied by a shape of all of the tapered edges of the internal reliefs of the key of the cap ensuring a certain tightening during the fitting of the cover by this key. In order to have the facility of an isotropic nesting, the cover preferably has a lateral surface of revolution around its axis of symmetry which is usually that of the neck it covers. The cover has for example a frustoconical or parabolic surface. Usually, and this is the case for the examples which follow, the cover comprises a circular cylindrical lateral surface.
Habituellement, le capuchon est monobloc, et le goulot et l'opercule sont monoblocs avec l'épaule par laquelle la tête surmoulée se raccorde à la jupe du tube. Les couples de matière utilisables pour l'opercule d'une part, c'est-à-dire habituellement aussi pour le goulot ou la tête du tube, et pour la clef du capuchon d'autre part, c'est-à-dire habituellement pour tout le capuchon, sont les suivants :
- A)- Opercule (tête) : PE BD (polyéthylène basse densité) réticulaire ou linéaire
- - Clef du capuchon (capuchon) : l'une des matières plastiques suivantes :
- - PE HD (polyéthylène haute densité)
- - PP (polypropylène)
- - Clef du capuchon (capuchon) : l'une des matières plastiques suivantes :
- B)- Opercule : PE HD (radicalaire ou linéaire);
- - Clef du capuchon : PP ou une des matières du sous-groupe (X)
- C)- Opercule PP;
- - Clef du capuchon : une des matières du sous-groupe (X)
- A) - Lid (head): PE BD (low density polyethylene) reticular or linear
- - Cap key (cap): one of the following plastics:
- - PE HD (high density polyethylene)
- - PP (polypropylene)
- - Cap key (cap): one of the following plastics:
- B) - Lid: PE HD (radical or linear);
- - Cap key: PP or one of the materials in subgroup (X)
- C) - PP cover;
- - Cap key: one of the materials in subgroup (X)
Lors de l'emboîtement de l'opercule par la clef du capuchon, emboîtement effectué en coiffant le goulot du capuchon et en appuyant un peu pour l'enfoncer, le "serrage" obtenu est de préférence compris entre 0,4 et 0,9 mm au diamètre, et de préférence encore compris entre 0.5 et 0,7 mm au diamètre, cela au moins sur une certaine hauteur, typiquement sur au moins 2 mm. Pour un opercule ayant une surface latérale lisse de révolution autour de son axe de symétrie, les cercles successifs perpendiculaires à l'axe commun de l'opercule et de la clef du capuchon et passant par les extrémités des arêtes effilées des reliefs intérieurs de la clef du capuchon ont à cet effet des diamètres inférieures de 0.4 à 0,9 mm, et de préférence de 0,5 à 0,7 mm, aux diamètres de la surface latérale de l'opercule qui leur correspondent.During the fitting of the lid by the key of the cap, fitting done by covering the neck of the cap and pressing a little to push it in, the "tightening" obtained is preferably between 0.4 and 0.9 mm in diameter, and preferably still between 0.5 and 0.7 mm in diameter, this at least over a certain height, typically over at least 2 mm. For a cover having a smooth lateral surface of revolution around its axis of symmetry, 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.
De plus, les arêtes effilées des reliefs de la clef du capuchon sont coupantes, dans les conditions d'emboîtage avec serrage indiquées ci-dessus, pour la surface latérale de l'opercuie qui est en matière plastique moins dure. Leur pouvoir coupant intervient pour la facilité de l'emboîtage ainsi que pour la qualité de la strie ou entaille obtenue qui conditionne l'efficacité de l'entraînement de l'opercule par rotation du capuchon. Dans l'entraînement d'un opercule à reliefs par une clef à reliefs s'emboîtant dans les reliefs de l'opercule, les surfaces des reliefs intervenant pour l'entraînement en rotation sont généralement limitées à des zones étroites où il y a contact. Par contraste, dans l'entraînement de l'opercule de l'invention, les petites portions d'arêtes effilées insérées dans la matière plastique de l'opercule interviennent par la totalité de leurs surfaces pour l'entraînement en rotation de l'opercule par la rotation du capuchon. Cette efficacité particulière du striage ou entaillage avec déformation en partie élastique de la matière plastique de l'opercule, striage qui se produit du haut vers le bas de l'opercule lors de l'enfoncement du capuchon et donc de sa clef. ainsi que la rigidité des insertions des arêtes effilées liée au serrage périphérique de l'embout par la clef, expliquent la facilité surprenante de l'entraînement en rotation de l'opercule par la rotation du capuchon avec le dispositif et selon le procédé de l'invention.In addition, the tapered edges of the reliefs of the key of the cap are cutting, under the nesting conditions with tightening indicated above, for the lateral surface of the cover which is made of less hard plastic. Their cutting power intervenes for the ease of fitting together as well as for the quality of the streak or notch obtained which conditions the efficiency of the drive of the cover by rotation of the cap. In the training of a relief cover by a relief key fitting into the reliefs of the cover, the relief surfaces involved in the rotation drive are generally limited to narrow areas where there is contact. In contrast, in the drive of the cover of the invention, 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. This particular efficiency of the streaking or notching with partially elastic deformation of the plastic material of the seal, streaking which occurs from the top to the bottom of the seal when the cap and therefore its key are pushed in. as well as the rigidity of the insertions of the tapered edges linked to the peripheral tightening of the endpiece by the key, explain the surprising ease of the rotary drive of the cover by the rotation of the cap with the device and according to the method of invention.
Pour obtenir une pénétration de l'embout, par striage ou entaillage par les arêtes effilées des reliefs de la clef du capuchon, facile et de qualité optimale pour l'entraînement en rotation de l'opercule, l'angle d'extrémité de ces arêtes effilées, en section perpendiculaire à l'axe de symétrie de la clef ainsi que de l'opercule en position d'emboîtage du récipient par le capuchon, est compris de préférence entre 7 et 20° et de préférence encore entre 10 et 16°. Ces conditions peuvent être associées à l'une ou l'autre des conditions préférentielles d'emboîtement avec serrage, mais il est recommandé d'avoir au minimum à la fois un "serrage" de 0.4 à 0.9 mm au diamètre et des angles d'extrémités des arêtes effilées compris entre 7 et 20°.To obtain penetration of the nozzle, by stripping or notching by the tapered edges of the reliefs of the key of the cap, easy and of optimal quality for the rotation drive of the seal, the end angle of these edges tapered, in section perpendicular to the axis of symmetry of the key as well as of the cover in position for fitting the container by the cap, 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 ends of tapered edges between 7 and 20 °.
Enfin, dans une structure particulière, les reliefs intérieurs de la clef du capuchon sont portés par une couronne dont l'extrémité s'emboîte facilement sur l'opercule, et ces reliefs intérieurs s'élargissent progressivement depuis leur extrémité inférieure, de sorte que le début de l'enfoncement du capuchon assure un bon centrage de la clef sur l'opercule et que le début du striage de la surface latérale de cet opercule par les arêtes effilées des reliefs intérieurs de la clef consiste en un entaillage progressif de la partie supérieure de cette surface latérale. L'élargissement progressif des reliefs intérieurs de la clef du capuchon, est de préférence réalisé sur une hauteur au moins égale à 2 fois la largeur maximale desdits reliefs. De plus, pour la bonne rigidité des reliefs intérieurs à arêtes effilées, il est dans le cas général préférable de maintenir leur largeur selon la direction radiale assez faible et typiquement comprise entre 0,3 et 1 mm.Finally, in a particular structure, 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 gradual notching 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. In addition, for the good rigidity of the interior reliefs with tapered edges, it is generally preferable to maintain their width in the radial direction quite small and typically between 0.3 and 1 mm.
L'invention a également pour objet un procédé d'ouverture d'un récipient à goulot surmonté d'un opercule d'inviolabilité à surface latérale lisse, dans lequel
- A) on approvisionne un capuchon en matière plastique comportant une clef à reliefs intérieurs, le capuchon pouvant coiffer le goulot et sa clef emboîtant alors ledit opercule, la clef du capuchon ayant les caractéristiques suivantes :
- - cette clef au moins est en matière plastique plus dure que la matière plastique du goulot et de l'opercule (comme la condition (b) concernant le dispositif);
- - ses reliefs intérieurs se terminent par des arêtes effilées dont les extrémités se situent, au moins sur une certaine hauteur, sur des cercles successifs perpendiculaires à l'axe du capuchon de diamètres plus faibles que les diamètres correspondants de l'opercule (comme les conditions (c) et (d) concernant le disposiif).
- B) on serre l'opercule et on strie sa surface latérale, en enfonçant le capuchon sur le goulot et donc sa clef sur ledit opercule.
- C) on fait tourner le capuchon par rapport au tube, dans un sens de rotation ou dans l'autre sens, jusqu'à rupture de l'opercule, et on écarte le capuchon.
- A) we supply a plastic cap comprising a key with internal reliefs, the cap being able to cover the neck and its key then fitting said cover, the key of the cap having the following characteristics:
- - this key at least is made of harder plastic than the plastic of the neck and the cover (as condition (b) concerning the device);
- - its interior reliefs end with tapered edges whose ends are located, at least over a certain height, on successive circles perpendicular to the axis of the cap with diameters smaller than the corresponding diameters of the cover (like the conditions (c) and (d) concerning the device).
- B) the cover is tightened and its lateral surface is streaked, by pushing the cap on the neck and therefore its key on said cover.
- C) the cap is rotated relative to the tube, in one direction of rotation or in the other direction, until the cap breaks, and the cap is moved aside.
De façon préférentielle, les extrémités des arêtes effilées des reliefs intérieurs de la clef du capuchon se situent, au moins sur une certaine hauteur -en pratique au moins sur 1,5 à 2 mm- sur des cercles successifs perpendiculaires à l'axe du capuchon de diamètres inférieurs de 0.4 à 0.9 mm aux diamètres correspondants de l'opercule, et lesdites arêtes effilées ont. en section perpendiculaire au même axe. un angle d'extrémité compris entre 7 et 20°.Preferably, the ends of the tapered edges of the internal reliefs of the cap key are located, at least over a certain height - in practice at least 1.5 to 2 mm - on successive circles perpendicular to the axis of the cap. diameters 0.4 to 0.9 mm lower than the corresponding diameters of the cover, and said tapered edges have. in section perpendicular to the same axis. an end angle between 7 and 20 °.
On obtient des résultats particulièrement bons avec les différentes conditions préférentielles déjà indiquées dans le cas du dispositif et concernant en particulier : les différences entre les diamètres intérieurs sur les extrémités des arêtes effilées intérieures de la clef du capuchon et les diamètres correspondants de l'opercule, l'angle d'extrémité de ces arêtes effilées; le choix des matières plastiques respectives pour la clef du capuchon, c'est-à-dire en général pour le capuchon monobloc, et pour l'opercule c'est-à-dire typiquement pour la tête surmoulée du tube.Particularly good results are obtained with the various preferential conditions already indicated in the case of the device and concerning in particular: the differences between the internal diameters on the ends of the internal tapered edges of the key of the cap and the corresponding diameters of the cover, the end angle of these tapered edges; the choice respective plastics for the key to the cap, that is to say in general for the one-piece cap, and for the cover, that is to say typically for the overmolded head of the tube.
Les exemples et les dessins qui les illustrent concernent le cas courant où, en position d'emboîtage, le goulot et son opercule d'étanchéité d'une part et le capuchon et sa clef d'autre part ont un axe longitudinal commun. Le goulot et l'opercule, ainsi que le capuchon ont alors une symétrie de révolution autour de l'axe précédent.The examples and the drawings which illustrate them relate to the common case where, in the fitting position, the neck and its sealing cap on the one hand and the cap and its key on the other hand have a common longitudinal axis. The neck and the cover, as well as the cap, then have a symmetry of revolution around the previous axis.

Le récipient (1) représenté sur la figure 1 comporte une jupe (2) de diamètre extérieur 33 mm en polyéthylène surmontée d'une tête surmoulée (3) d'épaisseur 0.8 à 1,2 mm en polyéthylène basse densité, tête (3) comprenant elle-même au-dessus de son épaule (4) un goulot (5) de diamètre extérieur 17 mm et de hauteur 12 mm portant un orifice de fantaisie (6) à 6 creux (7) séparés par 6 parties en relief (8), cet orifice (6) ayant un diamètre sur creux de 14 mm. Le goulot (5) et l'orifice (6) sont surmontés d'un opercule d'inviolabilité (9), qui comporte à sa base une jupe évasée (10), puis au-dessus une surface latérale (11) cylindrique circulaire de diamètre (PD) égal à 7,5 mm et de hauteur 6 mm, puis enfin une extrémité formant opercule (111) de hauteur 2 mm.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) comprising itself 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. The neck (5) and the orifice (6) are surmounted by a tamper-evident seal (9), which comprises at its base a flared skirt (10), then above a circular cylindrical lateral surface (11) of diameter (P D ) equal to 7.5 mm and 6 mm high, then finally an end forming a cover (111) 2 mm high.
Le capuchon (12) du récipient en cours d'enfoncement, est en polypropylène, il a un diamètre extérieur de 32 mm et une hauteur de 26 mm. Il porte à l'intérieur une couronne intermédiaire (13) de diamètre intérieur 17,5 mm et de hauteur 20 mm destinée à l'emboîtage du goulot (5), et une couronne centrale circulaire de hauteur 9 mm (14) portant sur sa surface cylindrique intérieure (15) de diamètre 8,0 mm 12 nervures en relief (16) en forme d'ailettes effilées.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
Ces ailettes effilées (16) visibles en coupe perpendiculaire à l'axe longitudinal (L) sur la figure 2 ont, selon cette coupe, un angle d'extrémité (« ) de 15°. Leur largeur dans la direction radiale, constante pour toutes les ailettes, est de 0,55 mm. Le diamètre (bd) du cercle perpendiculaire à l'axe (L) passant par les extrémités (17) des ailettes effilées (16) de la clef (14+16) du capuchon (12) est de 6,9 mm au niveau de cette coupe, et ce diamètre reste constant sur 6 à 7 mm de hauteur. Lors de l'emboîtement de l'opercule (9) par la clef du capuchon (14+16). les cercles de diamètre (φd) de cette clef ont donc 7,5-6,9 - 0,6 mm de moins que le diamètre (φD) de la surface latérale cylindrique de l'opercule (9).These tapered fins (16) visible in section perpendicular to the longitudinal axis (L) in Figure 2 have, according to this section, an end angle (") of 15 °. Their width in the radial direction, constant for all the fins, is 0.55 mm. The diameter (b 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. During the fitting of the cover (9) by the key of the cap (14 + 16). the circles of diameter (φ d ) of this key are therefore 7.5-6.9 - 0.6 mm less than the diameter (φ D ) of the cylindrical lateral surface of the cover (9).
La figure 3 montre plus clairement le début de l'engagement de la clef du capuchon (14+16) sur l'opercule (9). La portion d'extrémité (18) de la couronne (14) de la clef du capuchon est sur environ 1 mm libre de reliefs en forme d'ailettes effilées (16). Les reliefs des ailettes (16) commencent ensuite en s'élargissant progressivement de 0 à 0,55 mm sur 1,5 mm. Grâce à la portion d'extrémité (18) de la couronne (14) libre de reliefs et grâce à l'élargissement progressif (19) des reliefs des ailettes (16), l'engagement de la clef du capuchon (14+16) est dans tous les cas facile et progressif et assurera un bon centrage pour le début du striage de l'opercule (9) pour les ailettes (16). On a représenté sur la figure 3 les prolongements (20) des extrémités (17) des ailettes (16) en traits discontinus, qui viennent couper l'opercule de façon symétrique par rapport à l'axe (L), grâce à ces moyens de centrage. Il n'est pas nécessaire pour cet effet de centrage que l'intérieur de la clef du capuchon (14+16) commence par une portion de surface (18) libre de reliefs, mais cette portion libre (18) assure l'éloignement de l'élargissement progressif (19) des ailettes (16) par rapport au bord extrême de la couronne (14) et donne ainsi à cet élargissement (19) et aux ailettes (16) une protection vis-à-vis des chocs de manutention.Figure 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). FIG. 3 shows the extensions (20) of the ends (17) of the fins (16) in broken lines, which cut the cover symmetrically with respect to the axis (L), thanks to these means of centering. It is not necessary for this centering effect that the interior of the cap key (14 + 16) begins with a portion of surface (18) free of reliefs, but this free portion (18) ensures the separation of the progressive widening (19) of the fins (16) relative to the extreme edge of the crown (14) and thus gives this widening (19) and the fins (16) protection against handling shocks.
Lorsqu'on poursuit l'enfoncement du capuchon (12) et donc de sa clef (14+16), l'entaillage ou le striage de l'opercule (9) commence au niveau de l'extrémité haute (21) de sa surface latérale cylindrique (11). La figure 4 montre le capuchon (12) en position enfoncée sur le goulot (5) et l'opercule (9).When the cap (12) and therefore its key (14 + 16) is pushed further in, the notching or the stripping of the cover (9) begins at the upper end (21) of its surface cylindrical side (11). Figure 4 shows the cap (12) in the depressed position on the neck (5) and the cover (9).
A partir de cette position enfoncée, il suffit d'entraîner le capuchon (12) en rotation en maintenant le récipient tubulaire (1) avec l'autre main, dans un sens ou dans l'autre comme le schématise la double flèche (22) de la figure 4. La rupture de l'opercule (9) est facilement obtenue avec un angle de rotation relative de 30 à 40°, et l'opercule rompu (9) reste prisonnier de la clef (14+16) du capuchon (12) lorsque celui-ci est soulevé (figure 5), libérant ainsi l'orifice (6) du tube (1).From this depressed position, it suffices to drive the cap (12) in rotation while holding the tubular container (1) with the other hand, in one direction or the other as shown by the double arrow (22). of Figure 4. The rupture of the cover (9) is easily obtained with a relative angle of rotation of 30 to 40 °, and the broken cover (9) remains trapped in the key (14 + 16) of the cap ( 12) when the latter is raised (FIG. 5), thus freeing the orifice (6) from the tube (1).
Avec d'autres échantillons semblables, on a pu observer qu'on pouvait enfoncer le capuchon (12) sur l'opercule (9) puis le retirer et recommencer cette manoeuvre plus d'une dizaine de fois sans observer de difficultés, et qu'on obtenait ensuite aisément la rupture de l'opercule (9) par rotation du capuchon (12), comme décrit précédemment. Après les retraits des capuchons (12), on a observé à l'oeil que les surfaces latérales (11) des opercules (9) comportaient des stries fines, plus ou moins apparentes, commençant à l'extrémité haute (21) de ces surfaces latérales (11) et descendant sur 2 à 4 mm, l'espacement de ces stries ou rayures correspondant à l'espacement des ailettes (16).With other similar samples, it has been observed that the cap (12) can be pushed onto the cover (9) then removed and repeated this maneuver more than ten times without observing any difficulties, and that the rupture of the cover (9) was then easily obtained by rotation of the cap (12), as described above. After removing the caps (12), it was observed by eye that the lateral surfaces (11) of the lids (9) had fine, more or less apparent streaks, starting at the high end (21) of these surfaces lateral (11) and descending on 2 to 4 mm, the spacing of these streaks or stripes corresponding to the spacing of the fins (16).
On voit donc que le procédé d'ouverture de l'invention est efficace, malgré des différences apparentes de longueur entre les stries fines causées par les diverses ailettes effilées. On voit aussi que ces stries paraissent plus fines que les portions d'ailettes qui ont entaillé la paroi latérale des opercules, ce qui veut sans doute dire qu'il y a eu insertion de ces portions d'ailettes avec serrage élastique de la part de la matière plastique des parois d'opercules ainsi striées.It can therefore be seen that the opening method of the invention is effective, despite apparent differences in length between the fine streaks caused by the various tapered fins. We also see that these streaks appear finer than the portions of fins which have cut the lateral wall of the lids, which undoubtedly means that these portions of fins were inserted with elastic tightening on the part of the plastic material of the lid walls thus striated.
Le deuxième exemple de récipient (100) et de capuchon (120) selon l'invention (figur 6) montre les particularités suivantes :
- - le goulot (50) et la couronne intermédiaire (130) du capuchon (120) comportent respectivement des filetages (51) et (131) destinés au rebouchage du récipient (100) après rupture de l'opercule (90). par vissage du capuchon sur le goulot;
- - l'opercule (90) raccordé au bord de l'orifice circulaire (60) du goulot (50) par une zone de faiblesse amincie (91) comporte successivement une jupe inférieure (9) surmontée d'une coupelle (93) et une tête (94) comportant une surface latérale cylindrique (95);
- - le capuchon (120) comporte en son centre une clef constituée par une couronne (140) portant des reliefs en forme d'ailettes effilées (160) selon l'invention, avec entrée progressive. Le diamètre intérieur sur ailettes (e d) de la clef (140+160) est inférieur de 0,4 à 0,9 mm au diamètre extérieur (φD) de la surface latérale (95) de l'opercule (90). Le capuchon (120) et sa clef (140+160) sont monobloc et en matière plastique plus dure que celle de la tête du tube (100). En tournant le capuchon (120) enfoncé en rotation dans un sens ou dans l'autre selon la flèche (220), on obtient la rupture de l'opercule (90) grâce au procédé et au dispositif de "clef striante" de la présente invention. Ensuite, la jupe (92) rompue à pourtour extérieur légèrement conique ainsi que la coupelle (93) de l'opercule (90), opercule qui est alors prisonnier du capuchon (120), permettent le rebouchage étanche de l'orifice (60) du goulot (50), comme cela est connu en soi par notre demande de brevet EP-A- 0 119 145 et repris par les revendications 4 et 13 de ce document. De façon plus générale, tous les aménagements qui correspondent aux parties caractéristiques des revendications 3 à 11 et 13-14 de cette demande de brevet peuvent être utilisés avec l'opercule et la clef striante de la présente invention.
- - The neck (50) and the intermediate crown (130) of the cap (120) respectively comprise threads (51) and (131) intended for recapping the container (100) after rupture of the cover (90). by screwing the cap onto the neck;
- - The cover (90) connected to the edge of the circular orifice (60) of the neck (50) by a zone of thinned weakness (91) successively comprises a lower skirt (9) surmounted by a cup (93) and a head (94) having a cylindrical side surface (95);
- - The cap (120) has in its center a key constituted by a crown (140) carrying reliefs in the form of tapered fins (160) according to the invention, with progressive entry. The inside diameter on fins (e d ) of the key (140 + 160) is 0.4 to 0.9 mm less than the outside diameter (φ D ) of the lateral surface (95) of the cover (90). The cap (120) and its key (140 + 160) are in one piece and made of plastic harder than that of the head of the tube (100). By turning the cap (120) pressed in rotation in one direction or the other according to the arrow (220), one obtains the rupture of the cover (90) thanks to the process and to the "striating key" device of the present invention. Then, the skirt (92) broken with a slightly conical outer periphery as well as the cup (93) of the cover (90), a cover which is then trapped in the cap (120), allow the sealing of the orifice (60) neck (50), as is known per se from our patent application EP-A-0 119 145 and taken up by
claims 4 and 13 of this document. More generally, all the arrangements which correspond to the characteristic parts of claims 3 to 11 and 13-14 of this patent application can be used with the cover and the striating key of the present invention.
Le dispositif et le procédé d'ouverture de l'invention s'applique le plus souvent à des récipients tubulaires ayant un orifice circulaire de diamètre compris entre 5 et 15 mm, ou encore un orifice de fantaisie ayant un cercle d'injection de diamètre compris entre 5 et 15 mm. Les épaisseurs des zones de faiblesse soudées sont en général comprises entre 0,1 et 0,4 mm.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.
Ces récipients tubulaires sont typiquement munis d'un capuchon de diamètre compris entre 25 et 40 mm et, comme décrit par EP-A- 0 119 145 le couple d'ouverture par rupture de l'opercule d'inviolabilité est alors typiquement compris entre 10 et 90 N.m, et entre 10 et 30 N.m dans le cas des orifices de fantaisie surmontés d'opercules soudés de façon discontinue.These 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.
Le dispositif et le procédé de l'invention sont employés essentiellement dans le domaine des produits alimentaires pour des liquides, sirops, crèmes, des produits à l'état pâteux ou à l'état de gommes, et pour des produits dans un état divisé; dans le domaine des produits pharmaceutiques, hygiéniques ou cosmétiques; dans toutes les présentations ou consistances précédentes, et dans le domaine des produits chimiques ou de l'entretien.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.
