Description

La présente invention concerne plus spécialement les vaporisateurs dits rechargeables comportant un étui ou enveloppe extérieure présentant un bel aspect décoratif et qui peut être d'un prix de revient élevé et un conteneur intérieur dit «recharge» en un matériau tel que le verre, le métal ou une matière plastique qui est d'un prix de revient plus faible et qui peut être jeté après épuisement du produit qu'il contient. L'enveloppe extérieure est d'une manière usuelle constituée en deux parties qui peuvent être séparées pour permettre d'y insérer la recharge. Les deux parties forment, l'une la paroi latérale et le fond ou la partie supérieure, l'autre inversement la partie supérieure dite couvercle ou le fond.The present invention relates more specifically to so-called refillable vaporizers comprising a case or outer envelope having a beautiful decorative appearance and which may be of a high cost price and an inner container known as a "refill" made of a material such as glass, metal or a plastic material which has a lower cost price and which can be discarded after the product it contains has been used up. The outer envelope is usually made up of two parts which can be separated to allow the refill to be inserted therein. The two parts form, one the side wall and the bottom or the upper part, the other inversely the upper part called the cover or the bottom.

Le problème rencontré dans la réalisation de ces vaporisateurs rechargeables réside essentiellement dans l'assemblage des deux parties de l'enveloppe extérieure, cet assemblage devant assurer une bonne solidarisation des deux parties pour éviter une ouverture accidentelle, ce qui exclut les assemblages à simple emboîtement par frottement. Les assemblages les plus couramment utilisés sont ceux dits à vis ou à baïonnette. Ces assemblages ne sont toutefois utilisables que dans le cas d'assemblage entre deux sections circulaires ou sensiblement circulaires. L'assemblage à vis oblige à des épaisseurs plus grandes puisque les filets doivent être taillés dans les épaisseurs des jupes qui s'emboîtent et il nécessite de prévoir des reliefs extérieurs sur les deux parties pour permettre d'exercer manuellement le couple de vissage et de dévissage, ce dernier notamment pouvant être très élevé dans le cas d'un encrassement ou difficile à produire avec des surfaces de prise grasses ou mouillées. Ces prises extérieures nuisent à l'aspect d'ensemble de l'enveloppe. L'assemblage à baïonnette présente les mêmes inconvénients quoiqu'il permette, si l'on accepte un léger jeu entre la jupe extérieure et la jupe d'emboïtement interne, une légère ovalisation de la section.The problem encountered in the production of these refillable vaporizers essentially resides in the assembly of the two parts of the outer casing, this assembly having to ensure good joining of the two parts to avoid accidental opening, which excludes assemblies with simple interlocking by friction. The most commonly used assemblies are those called screw or bayonet. These assemblies can however only be used in the case of assembly between two circular or substantially circular sections. The screw assembly requires greater thicknesses since the threads must be cut in the thicknesses of the skirts which fit together and it requires the provision of external reliefs on the two parts to allow manual exertion of the screwing and unscrewing, the latter in particular being able to be very high in the case of fouling or difficult to produce with greasy or wet grip surfaces. These external sockets detract from the overall appearance of the envelope. The bayonet connection has the same disadvantages, although it allows, if we accept a slight clearance between the outer skirt and the internal interlocking skirt, a slight ovalization of the section.

Dès que la section de l'enveloppe extérieure s'écarte de la forme circulaire, le seul assemblage connu à ce jour est l'assemblage à emboïtement à friction.As soon as the section of the outer casing deviates from the circular shape, the only assembly known to date is the friction fit assembly.

Or, pour des raisons esthétiques ou d'encombrement, on cherche fréquemment des formes non circulaires de section carrée, polygonale, rectangulaire ou ovale. Le même problème se pose d'ailleurs avec tous les conteneurs de même définition que l'étui ou l'enveloppe d'un vaporisateur rechargeable tels que des coffrets qui doivent pouvoir être ouverts pour donner accès aux produits qu'ils contiennent.However, for aesthetic or bulk reasons, one frequently seeks non-circular shapes of square, polygonal, rectangular or oval section. The same problem also arises with all containers of the same definition as the case or the envelope of a refillable vaporizer such as boxes which must be able to be opened to give access to the products which they contain.

FR-A-2 537 093 décrit un étui contenant un dispositif actionnable par un poussoir, l'étui étant constitué par deux coquilles pouvant être écartées l'une de l'autre lorsque des moyens daccrochage sont décrochés par enfoncement du buton poussoir amené par rotation à avoir une orientation différente de celle de la position d'utilisation normale. Cette réalisation n'est toutefois applicable que lorsque les deux parties de l'étui sont articulées autour d'un axe perpendiculaire à la direction de déplacement exial du bouton poussoir, déplacement qui dégage un verrou. Les enseignements de ce brevet ne sont pas applicables à un étui dont les deux parties sont assemblées par emboîtement de forme de jupes.FR-A-2 537 093 describes a case containing a device that can be actuated by a pusher, the case being constituted by two shells which can be spaced from each other when hooking means are released by depressing the push button brought in by rotation to have an orientation different from that of the normal use position. This embodiment is however only applicable when the two parts of the case are articulated about an axis perpendicular to the direction of exial movement of the push button, movement which releases a lock. The teachings of this patent are not applicable to a case in which the two parts are assembled by interlocking in the form of skirts.

Le résultat est atteint, conformément à l'învention et selon une première caractéristique, par le fait que dans une enveloppe en deux parties assemblées par emboîtement de forme de jupes cylindriques de section droite non circulaire, la jupe interne présente, dans au moins deux parties opposées, distantes angulairement des parties de sa section droite non circulaire présentant le plus grand écartement, des tenons en saillie vers l'extérieur ou des rainures et la pièce portant la jupe externe comporte un verrou monté à rotation autour de son centre géométrique, ce verrou présentant deux ailes opposées susceptibles par rotation, à l'aide d'un bouton de commande faisant saillie au-dessus de la surface supérieure de ladite pièce, d'être engagées sous lesdits tenons ou dans lesdites rainures.The result is achieved, in accordance with the invention and according to a first characteristic, by the fact that in an envelope in two parts assembled by interlocking in the form of cylindrical skirts of non-circular cross section, the internal skirt has, in at least two parts opposite, angularly distant from the parts of its non-circular cross section having the greatest spacing, studs projecting outwards or grooves and the part carrying the external skirt comprises a lock mounted for rotation around its geometric center, this lock having two opposite wings capable of rotation, using a control button projecting above the upper surface of said part, to be engaged under said studs or in said grooves.

De préférence le verrou comporte des butées limitant son angle de rotation par coopération avec des butées complémentaires portées par la pièce sur laquelle il est monté à rotation et son bouton de commande a une section non cylindrique pour améliorer la prise permettant d'exercer le couple de verrouillage ou de déverrouillage.Preferably, the bolt includes stops limiting its angle of rotation by cooperation with complementary stops carried by the part on which it is rotatably mounted and its control button has a non-cylindrical section to improve the grip enabling the torque to be exerted. locking or unlocking.

Selon une autre caractéristique applicable notamment aux pulvérisateurs ou vaporisateurs, la partie portant le verrou constitue le couvercle de l'enveloppe et le bouton de commande est creux et comporte un passage axial pour le passage de l'organe de pulvérisation.According to another characteristic applicable in particular to sprayers or sprays, the part carrying the lock constitutes the cover of the envelope and the control button is hollow and has an axial passage for the passage of the spraying member.

Selon une autre caractéristique un organe élastique compressible est monté au fond du corps de l'enveloppe et pousse la recharge contre le couvercle pour mettre en appui les ailes du verrou contre les surfaces d'appui des tenons ou rainures.According to another characteristic, a compressible elastic member is mounted at the bottom of the body of the envelope and pushes the refill against the cover to support the wings of the lock against the bearing surfaces of the tenons or grooves.

Selon encore une autre caractéristique, l'appui entre le bouton de commande et la surface d'appui sur le couvercle s'effectue selon une surface bombée non de révolution de manière à réaliser un effet de came élastique, le déverrouillage s'effectuant avec une compression supplémentaire de l'organe élastique.According to yet another characteristic, the pressing between the control button and the bearing surface on the cover takes place on a curved surface which is not of revolution so as to produce an elastic cam effect, the unlocking being effected with a additional compression of the elastic organ.

Dans les dessins, la référence 1 désigne le corps de l'enveloppe du vaporisateur, la référence 2 le capot ou capuchon qui vient se fixer sur le corps pour enfermer la tête de vaporisation, la référence 3 désigne la recharge, la référence 4 le poussoir de la pompe de vaporisation de la recharge, la référence 51a frette ou couvercle du corps de l'enveloppe, la référence 6 le verrou et la référence 7 le coussin élastique placé au fond de l'enveloppe.In the drawings, the reference 1 designates the body of the envelope of the vaporizer, the reference 2 the hood or cap which is fixed on the body to enclose the spray head, the reference 3 indicates the refill, the reference 4 the pusher of the refill spray pump, the reference 51a hoop or cover of the envelope body, the reference 6 the lock and the reference 7 the elastic cushion placed at the bottom of the envelope.

Le corps 1 de l'enveloppe du vaporisateur comme le capot 2 sont réalisés en un matériau présentant un bel aspect de surface. Ils sont de forme cylindrique avec une directrice ou section droite ovale. Le corps 1 présente à sa partie supérieur une partie amincie 8 pour l'emboîtement par la jupe 9 de la frette 5. Cette partie 8 porte, aux deux points diamétralement opposés du petit axe de la section droite, des languettes 10 en saillie vers l'intérieur, le tracé du bord intérieur de ces languettes étant ovalisé.The body 1 of the spray envelope as the cover 2 are made of a material having a beautiful surface appearance. They are cylindrical in shape with a director or oval cross section. The body 1 has at its upper part a thinned part 8 for fitting by the skirt 9 of the hoop 5. This part 8 carries, at the two diametrically opposite points of the minor axis of the cross section, tongues 10 projecting towards the interior, the layout of the interior edge of these tabs being ovalized.

Le capot 2 s'emboîte pour la fermeture sur un redan 11 de la jupe 9 de la frette et il y est maintenu de manière amovible pour encliquetage de tétons 12 prévus sur la face cylindrique de ce redan dans des encoches correspondantes prévues près du bord de la surface interne du capot.The cover 2 fits into the closure on a step 11 of the skirt 9 of the hoop and is held there removably for snap-fastening of the pins 12 provided on the cylindrical face of this step in corresponding notches provided near the edge of the internal surface of the cover.

La recharge 3 est constituée en un matériau insensible au produit conditionné et le plus souvent en verre. Sur son goulot est serti un bouchon 13 qui maintient la pompe et le poussoir 4 de l'organe de pulvérisation du type connu. La section de la recharge est telle qu'elle puisse être engagée dans le corps 1 de l'enveloppe. A cet effet ses faces latérales présentent des parties en creux 14 pour permettre le passage des languettes 10. La recharge s'appuie au fond du corps sur le coussin élastique 7 qui est constitué par une bague portant des languettes élastiques 15 dirigées radialement vers le centre.The refill 3 is made of a material insensitive to the packaged product and most often made of glass. On its neck is crimped a plug 13 which holds the pump and the plunger 4 of the spraying member of the known type. The refill section is such that it can be engaged in the body 1 of the envelope. For this purpose its side faces have recessed portions 14 to allow the passage of the tongues 10. The refill is supported at the bottom of the body on the elastic cushion 7 which is constituted by a ring carrying elastic tongues 15 directed radially towards the center .

La frette 5 constitue un couvercle qui, comme décrit ci-dessus, maintient la recharge 3 dans le corps 1. Elle s'emboîte par sa jupe 9 sur le bord aminci 8 du corps et, par le redan 11, à l'intérieur du bord libre du capot 2. Elle comporte dans sa surface supérieure un orifice désigné par la référence générale 16, cet orifice étant oblong avec sa plus grande dimension selon le grand axe de l'ovale de la frette. Les deux extrémités de l'orifice 16 se trouvant sur le grand axe forment des encoches 17 pour le passage des pattes à tenons 18 du verrou qui sera décrit ci-après. A partir des coins opposés 19 de ces encoches, l'orifice est délimité par deux arcs de cercles 20 et 21 centrés sur l'axe de l'ovale, l'arc de cercle 20 ayant un rayon légèrement plus grand que l'arc de cercle 21. Ces parties 20-21 sont raccordées à l'autre coin 22 des encoches 17 par des arcs de cercles 23-24 ayant respectivement les mêmes rayons que les arcs de cercles 21 et 20. Le raccordement entre les arcs de cercle 20-23 et 21-24 forme une butée à la rotation 25. La surface supérieure 26 de la frette est bombée de façon ovoïde pour assurer un effet de came avec la face inférieure du verrou.The hoop 5 constitutes a cover which, as described above, maintains the refill 3 in the body 1. It fits by its skirt 9 on the thinned edge 8 of the body and, by the step 11, inside the free edge of the cover 2. It has in its upper surface an orifice designated by the general reference 16, this orifice being oblong with its largest dimension along the major axis of the oval of the hoop. The two ends of the orifice 16 located on the major axis form notches 17 for the passage of the stud tabs 18 of the lock which will be described below. From the opposite corners 19 of these notches, the orifice is delimited by two arcs of circles 20 and 21 centered on the axis of the oval, the arc of a circle 20 having a radius slightly larger than the arc of circle 21. These parts 20-21 are connected to the other corner 22 of the notches 17 by arcs of circles 23-24 having respectively the same radii as the arcs of circles 21 and 20. The connection between the arcs of circle 20- 23 and 21-24 forms a stop for rotation 25. The upper surface 26 of the hoop is ovoidally curved to provide a cam effect with the underside of the lock.

Le verrou 6 comporte un corps en cuvette 27 de section droite ovale avec une jupe 28. A partir des deux points aux extrémités du petit axe, la jupe 28 se prolonge par des pattes 29 qui portent les tenons 18. L'écartement des tenons 18 et la longueur des pattes 29 sont tels que, lorsque le verrou est en appui sur la face supérieure de la frette 5 et tourné pour que les tenons soient orientés selon le petit axe de la frette, les tenons 18 viennent s'engager sous les languettes 10 du corps 1 de l'enveloppe.The lock 6 comprises a bowl-shaped body 27 of oval cross section with a skirt 28. From the two points at the ends of the minor axis, the skirt 28 is extended by lugs 29 which carry the lugs 18. The spacing of the lugs 18 and the length of the legs 29 are such that, when the lock is in abutment on the upper face of the hoop 5 and rotated so that the lugs are oriented along the minor axis of the hoop, the lugs 18 come to engage under the tongues 10 of body 1 of the envelope.

A partir du fond 27 de la cuvette descendent deux languettes en secteurs cylindriques 30 et 31 centrés sur l'axe du verrou et symétriques par rapport au grand axe de l'ovale, les rayons extérieurs de ces secteurs cylindriques 30 et 31 correspondant aux rayons des arcs de cercle 20 et 21 respectivement et leur développement angulaire étant voisin de 90°. Chacune des languettes porte, en-dessous du bord de la jupe 28, un bourrelet 32 qui est distant de la surface contenant le bord de la jupe 28 d'un peu plus que l'épaisseur de la frette pour permettre la fixation, par encliquetage de ces bourrelets sous le bord de l'orifice 16 de la frette, dudit verrou 6 sur la frette 5. La surface du bord du verrou s'adapte au bombé de la surface supérieure de la frette. Le fond du verrou présente en son centre un orifice circulaire 33 pour le passage du poussoir 4 de la pompe.From the bottom 27 of the bowl descend two tongues in cylindrical sectors 30 and 31 centered on the axis of the lock and symmetrical with respect to the major axis of the oval, the external radii of these cylindrical sectors 30 and 31 corresponding to the radii of the circular arcs 20 and 21 respectively and their angular development being close to 90 °. Each of the tabs carries, below the edge of the skirt 28, a bead 32 which is distant from the surface containing the edge of the skirt 28 of a little more than the thickness of the hoop to allow fixing, by snap-fastening of these beads under the edge of the orifice 16 of the hoop, of said latch 6 on the hoop 5. The surface of the edge of the latch adapts to the camber of the upper surface of the hoop. The bottom of the lock has in its center a circular orifice 33 for the passage of the plunger 4 of the pump.

Comme exposé ci-dessus, le montage du verrou 6 sur la frette 5 s'effectue en engageant les pattes 29 portant les tenons 18 dans les encoches 17, avec la patte 30 en secteur cylindrique de plus grand rayon en face de l'arc de cercle 20 de l'orifice 16. La solidarisation se fait alors en forçant le verrou 6 sur la frette pour faire passer les bourrelets 32 sous la surface de la frette. Le verrou 6 peut alors tourner par rapport à la frette 5, l'amplitude de la rotation étant limitée à 90° par butée des bords de la languette en secteur cylindrique 30 de plus grand rayon contre les raccordements 25.As explained above, the mounting of the latch 6 on the hoop 5 is effected by engaging the lugs 29 carrying the tenons 18 in the notches 17, with the lug 30 in a cylindrical sector of larger radius opposite the arc of circle 20 of the orifice 16. The connection is then made by forcing the latch 6 on the hoop to pass the beads 32 under the surface of the hoop. The lock 6 can then rotate relative to the hoop 5, the amplitude of the rotation being limited to 90 ° by abutment of the edges of the tongue in a cylindrical sector 30 of larger radius against the connections 25.

En position de fermeture du vaporisateur, la frette 5 est emboîtée par sa jupe 9 sur le bord aminci 8 du corps 1 de l'enveloppe et maintient la recharge 3 avec une légère compression du coussin élastique 7. Les tenons 18 sont engagés sous les languettes 10, ce qui bloque la frette en position sur le corps 1 de l'enveloppe. Pour recharger le vaporisateur, c'est-à-dire changer le recharge 3, on fait tourner le verrou 6 d'un quart de tour dans le sens de la flèche F (figure 2), ce qui dégage les tenons 18 des languettes 10 et l'ensemble constitué par la frette 5 et le verrou 6 peut alors être extrait dans le sens de la fléche S (figure 3). Après échange de la recharge 3, la fermeture s'effectue par les manoeuvres inverses.In the closed position of the vaporizer, the hoop 5 is fitted by its skirt 9 on the thinned edge 8 of the body 1 of the envelope and maintains the refill 3 with a slight compression of the elastic cushion 7. The pins 18 are engaged under the tabs 10, which blocks the hoop in position on the body 1 of the envelope. To recharge the vaporizer, that is to say change the refill 3, the lock 6 is turned a quarter of a turn in the direction of the arrow F (FIG. 2), which releases the pins 18 from the tabs 10 and the assembly constituted by the hoop 5 and the latch 6 can then be extracted in the direction of the arrow S (FIG. 3). After exchanging the refill 3, closing is carried out by reverse operations.

Claims (7)

1. A case in two portions, assembled by latching, notably a refillable sprayer comprising two portions assembled by a shape fit of cylindrical skirts of non circular cross section, characterized in that the inner skirt (8) has, in at least two opposite portions, angularly distant from the portions of its non circular cross section having the largest spacing, studs (10) protruding inwardly or grooves, the portion (5) carrying the outer skirt (9) comprising a latch (6) rotatably mounted about its geometrical center, said latch having two opposite wings (18) adapted, when rotated with the assistance of a control knob (27) projecting above the upper surface (26) of said part (5), for engagement underneath said studs (10) or inside said grooves.
2. A case according to claim 1, wherein latch (6) is formed with abutments (30) limiting its angle of rotation by cooperating with matching abutments (25) carried by part (5) on with it is rotatably mounted, and wherein its control knob (27) is of a non circular shape.
3. A case according to any one of claims 1 and 2, forming the envelope of a refill (3) forming a sprayer or vaporizer, wherein part (5) carrying latch (6) forms the cover of the envelope and the control knob (27) is hollow and formed with an axial passage (33) for the passage of the spraying member (4).
