- the present invention relates to a razor, in particular disposable or with a head disposable, whose blade (s) are protected, when acquired by the user, by a cover or a protective housing.
- WO 97/19612 has already proposed a solution consisting in providing temporary fixing means, fixed both on the protective cover and on the head of the razor, said means consisting in particular in an adhesive strip to be manually removed or broken to be able to remove the protective cover from the shaver and use it.
- the goal set by the applicant is to propose a solution different to this problem which does not require the implementation of a packaging and which overcomes the disadvantages of the solution proposed by the document WO 97/19612.
- the razor of the invention which, in known manner, the head is provided with a protective member in which it removably fits to protect the blade (s) cutting before and possibly after use and which comprises a part able to be broken during the first removal of the protective caoot.
- the part in question is a tongue which is fixed either on the head or on the protective member and which comes to bear respectively either on a part of the protective member either on a part of the head so as to be broken during the first separation of the protective organ and the head.
- the tongue is an integral part of one of the elements (head or protective organ) and this is the usual gesture of separation of two elements that cause the rupture of the tongue.
- the noise caused by the rupture of the tongue constitutes a audible warning, confirming to the user that the protective device which has been placed during assembly of the shaver has not yet been removed and therefore the use he is going to make is indeed a first use.
- the tongue is fixed to the head of the razor to protect the cutting blade (s) before and after use, depending on a first variant of the invention, the tongue is fixed to the head of the razor and engages with part of the protective cover upon removal of it.
- the user removes the protective cover, he is obliged to exert a certain traction on the razor in order to dislodge the hood protector of the razor head.
- part of the cover engages on the tongue and, according to the invention, breaks it.
- the protective cover has on its inner face, a shoulder with an internal rectilinear surface, which is substantially parallel to the plane of the tongue when the cover is placed on the head of the razor and with an external convex surface.
- it is the internal rectilinear surface which engages with the tongue and which communicates to it the force necessary for its rupture when removing the cover.
- the convex surface allows the fitting of the cover on the head of the razor despite the presence of the tongue; because of the convex shape, there is an action progressive mechanics on the tongue which causes it to bend without breaking.
- the shoulder with external convex surface and internal rectilinear surface constitutes the longitudinal edge of the cover protective.
- the tab is on the underside of the head of the Shaver.
- a disposable razor made of elements obtained by molding or injection of plastic, the part capable of being broken during the first removal of the protective cover made integral part of one of said elements of the head.
- the part acting as first-time audible indicator is a fixed tab on the inside of the protective cover and engaging with a part of the razor head when removing said cover.
- each disposable head is inserted into a protective housing in which said head removably fits, of the general type known from US-A-4,285,428 according to claim 9
- said system comprises at least one tab capable of being broken during first removal of the head from its housing, in the same conditions as above.
- the razor 1 comprises a head 2 and a handle not shown, said head 2 being equipped with a cutting blade 3. Being a razor disposable, this head 2 is made up of various elements obtained by injection or molding of plastic material, for example polystyrene and assembled by any appropriate means.
- the razor 1 also includes a protective cover 4 which wraps the entire front part 5 of the head 2 and whose function is to protect the cutting blade 3.
- This protective cover 4 is designed to snap into place, removably, on said front part 5. Its holding in position, in the illustrated configuration, is obtained by any known means, for example thanks to the presence of nipples, practiced by thermal punching on the protective cover, said pins coming apply in recessed parts of the razor head, creating a some resistance for removing the protective cover 4.
- the head 2 of the razor 1, including its protective cover 4 further comprises a tongue capable of be broken during the first removal of the protective cover 4.
- This part constitutes an audible indicator, guaranteeing that the cover 4 has never been removed since its initial installation on the head 2.
- this tongue 6 is an integral part of one of the elements 7 obtained by injection or molding of a plastic material.
- This tongue 6 is arranged under the lower face 2 a of the head 2, substantially perpendicular to said face 2 a .
- the longitudinal edge 4a of the protective cover 4 which is intended to be placed at said lower face 2a of the head 2 is terminated by a shoulder 8 facing the interior of the protective cap 4.
- This shoulder 8 has a shape in quarter olive, with an external convex surface 8 a and an internal rectilinear surface 8 b .
- the convex surface 8 a which is applied to the tongue 6. Due to the curvature of this convex surface 8 a , the tongue undergoes a progressive force which makes it bend, without breaking.
- the rectilinear inner surface 8 b which is applied to the tongue 6 applying a high instantaneous force that is sufficient to break the tab 6 and to obtain the significant sound signal , according to the invention, of the first use.
- the rectilinear inner surface 8 b is preferably parallel to the plane of the tongue 6; moreover, the thickness of the tongue 6 must be sufficiently small so that the mechanical resistance necessary to obtain the rupture is compatible with the force usually used by the user to remove the protective cover 4.
- the present invention is not limited to the precise embodiment which has just been described by way of non-exhaustive example. We could indeed have on the underside 2 a of the head 2 a succession of tabs 6, offset to each other in the direction of movement of the internal surface 8 b when removing the cover 4, inducing a succession of ruptures and so a cascading sound effect.
- the removal of the protective cover 4 takes place in a direction illustrated by the arrow F in the figure.
- Other forms of protective covers can be implemented, according to the invention, including those whose removal takes place in a longitudinal direction relative to the direction of the cutting blades, direction which is perpendicular to the plane of the section of the single figure. In this case of course the bearing surface will no longer be in a direction longitudinal as above but in a transverse direction.
- the present invention applies not only to razors disposable as described above but also to the shaving comprising a razor with disposable heads, said heads being sold in batches and inserted in protective housings, each head being nested in the corresponding housing.
- the user presents the razor without head facing the housing, introduces in the head the means of attachment and exercises a pull so as to bring the head out of the housing in which it is fitted. Possibly he can, if he wishes, replace after use, the head in its housing by proceeding in reverse which has just been described.
- the razor system comprises a tongue capable of being broken during the first removal of the head from its housing.
- This tab is fixed either in the housing or on the head under conditions similar to what was described in the example above, that is to say respectively engaging either with a part of the head either with part of the housing so as to be broken during the first removal of the head from its housing. So when the user removes the head for the first time after acquisition housing, he perceives the desired sound effect which guarantees him that it is first use for the head he will use

Abstract
Description
La présente invention concerne un rasoir, notamment jetable ou à tête jetable, dont la ou les lames sont protégées , lors de l'acquisition par l'utilisateur, par un capot ou un logement protecteur.The present invention relates to a razor, in particular disposable or with a head disposable, whose blade (s) are protected, when acquired by the user, by a cover or a protective housing.
Lorsqu'il achète un rasoir, l'utilisateur ne peut avoir la certitude que celui-ci n'a pas déjà servi ou que la lame n'a pas été altérée d'une manière ou d'une autre. Cette incertitude est d'autant plus gênante dans le cas d'un rasoir jetable ou d'une tête jetable dont, par définition, la durée de vie est relativement faible, de l'ordre de 5 à 7 utilisations en moyenne. Certes la plupart des rasoirs jetables sont pourvus d'un capot protecteur qui s'emboíte sur la tête du rasoir pour protéger la ou les lames de coupe. Cependant la présence de ce capot protecteur n'est pas suffisante pour apporter une garantie réelle à l'utilisateur puisque ledit capot est parfaitement amovible, étant destiné à être repositionné sur la tête du rasoir après chaque utilisation. Il en est de même pour les têtes jetables qui sont insérées dans des logements protecteurs, dans la mesure où il est possible de repositionner la tête jetable après usage dans son logement.When buying a razor, the user cannot be sure that it has not already been used or that the blade has not been tampered with one way or another. This uncertainty is all the more troublesome in the case of a disposable razor or a disposable head whose, by definition, the lifespan is relatively short, of the order of 5 to 7 uses in average. Certainly most disposable razors have a hood protector which fits over the head of the razor to protect the cutting blades. However, the presence of this protective cover is not sufficient to provide a real guarantee to the user since said cover is perfectly removable, being intended to be repositioned on the shaver head after each use. It is the same for the heads disposable which are inserted in protective housings, in the since it is possible to reposition the disposable head after use in his accommodation.
Bien sûr une solution consiste à vendre le rasoir ou la tête jetable dans un emballage adéquat qu'il est nécessaire de détruire pour se saisir du rasoir ou de la tête. Cependant dans ce cas, pour être totalement efficace, il est nécessaire qu'il y ait un emballage par rasoir ou par tête. En effet lorsqu'une pluralité de rasoirs ou de têtes sont vendus dans le même emballage, une fois que celui-ci est ouvert, l'utilisateur n'est plus à même de savoir si l'un ou l'autre des rasoirs (ou têtes) a été ou non utilisé , question qui peut se poser lorsque les rasoirs (ou têtes) sont à disposition de plusieurs personnes.Of course one solution is to sell the razor or the disposable head in an adequate packaging which it is necessary to destroy to seize razor or head. However in this case, to be totally effective, it is necessary that there is a packaging per razor or per head. Indeed when a plurality of razors or heads are sold in the same packaging, once it is opened, the user is no longer able to know whether one or the other of the razors (or heads) has been used, question which can arise when the razors (or heads) are available to several people.
On a déjà proposé, par le document WO 97/19612 une solution consistant à prévoir des moyens de fixation temporaire, fixés, à la fois sur le capot protecteur et sur la tête du rasoir, lesdits moyens consistant notamment en une bande adhésive devant être manuellement enlevée ou cassée pour pouvoir retirer le capot protecteur du rasoir et utiliser celui-ci.WO 97/19612 has already proposed a solution consisting in providing temporary fixing means, fixed both on the protective cover and on the head of the razor, said means consisting in particular in an adhesive strip to be manually removed or broken to be able to remove the protective cover from the shaver and use it.
Cette solution nécessite la mise en oeuvre de moyens supplémentaires, ce qui complique la fabrication du rasoir et qui nécessite pour l'utilisateur une opération particulière à la quelle il n'est pas habitué.This solution requires the implementation of means which complicates the manufacturing of the razor and which requires a particular operation for the user which is not not used to.
Le but que s'est fixé le demandeur est de proposer une solution différente à ce problème qui ne nécessite pas la mise en oeuvre d'un emballage et qui pallie les inconvénients de la solution proposée par le document WO 97/19612.The goal set by the applicant is to propose a solution different to this problem which does not require the implementation of a packaging and which overcomes the disadvantages of the solution proposed by the document WO 97/19612.
Ce but est atteint par un rasoir selon la revendication 1 et un système de rasage selon la revendication 9.This object is achieved by a razor according to claim 1 and a shaving system according to claim 9.
Ce but est parfaitement atteint par le rasoir de l'invention dont , de manière connue, la tête est pourvue d'un organe protecteur dans lequel elle s'emboíte de manière amovible pour protéger la ou les lames de coupe avant et éventuellement après usage et qui comporte une pièce apte à être brisée à l'occasion du premier retrait du caoot protecteur.This object is perfectly achieved by the razor of the invention, which, in known manner, the head is provided with a protective member in which it removably fits to protect the blade (s) cutting before and possibly after use and which comprises a part able to be broken during the first removal of the protective caoot.
Selon l' invention, la pièce en question est une languette qui est fixée soit sur la tête soit sur l'organe protecteur et qui vient en appui respectivement soit sur une partie de l'organe protecteur soit sur une partie de la tête de manière à être brisée lors de la première désolidarisation de l'organe protecteur et de la tête.According to the invention, the part in question is a tongue which is fixed either on the head or on the protective member and which comes to bear respectively either on a part of the protective member either on a part of the head so as to be broken during the first separation of the protective organ and the head.
Ainsi, la languette est partie intégrante de l'un des éléments (tête ou organe protecteur) et c'est le geste habituel de désolidarisation des deux éléments qui provoque la rupture de la languette.Thus, the tongue is an integral part of one of the elements (head or protective organ) and this is the usual gesture of separation of two elements that cause the rupture of the tongue.
Le bruit provoqué par la rupture de la languette constitue un témoin sonore, confirmant à l'utilisateur que l'organe protecteur qui a été placé lors du montage du rasoir n'a pas encore été retiré et donc que l'usage qu'il va faire est bien un premier usage.The noise caused by the rupture of the tongue constitutes a audible warning, confirming to the user that the protective device which has been placed during assembly of the shaver has not yet been removed and therefore the use he is going to make is indeed a first use.
S'agissant d'un rasoir jetable ou d'un rasoir à tête jetable, pourvu d'un capot protecteur s'emboítant de manière amovible sur la tête du rasoir pour protéger la ou les lames de coupe avant et après usage, selon une première variante de l'invention, la languette est fixée sur la tête du rasoir pour protéger la ou les lames de coupe avant et après usage, selon une première variante de l'invention, la languette est fixée sur la tête du rasoir et vient en prise avec une partie du capot protecteur lors du retrait de celui-ci. Lorsque l'utilisateur retire le capot protecteur , il est obligé d'exercer une certaine traction sur le rasoir en vue de déboíter le capot protecteur de la tête du rasoir. Lors du déplacement relatif entre le capot et la tête, une partie du capot vient en prise sur la languette et , conformément à l'invention, brise celle-ci.In the case of a disposable razor or a razor with a disposable head, provided a protective cover removably fitting onto the head of the razor to protect the cutting blade (s) before and after use, depending on a first variant of the invention, the tongue is fixed to the head of the razor to protect the cutting blade (s) before and after use, depending on a first variant of the invention, the tongue is fixed to the head of the razor and engages with part of the protective cover upon removal of it. When the user removes the protective cover, he is obliged to exert a certain traction on the razor in order to dislodge the hood protector of the razor head. During relative movement between the hood and the head, part of the cover engages on the tongue and, according to the invention, breaks it.
Dans un mode préféré de réalisation, le capot protecteur présente sur sa face intérieure, un épaulement avec une surface rectiligne interne, qui est sensiblement parallèle au plan de la languette lorsque le capot est placé sur la tête du rasoir et avec une surface convexe externe. Dans ce mode de réalisation, c'est la surface rectiligne interne qui vient en prise avec la languette et qui communique à celle-ci la force nécessaire à sa rupture lors du retrait du capot. Par contre la surface convexe permet la mise en place du capot sur la tête du rasoir malgré la présence de la languette ; en effet du fait de la forme convexe, il y a une action mécanique progressive sur la languette qui entraíne celle-ci à se courber sans se rompre.In a preferred embodiment, the protective cover has on its inner face, a shoulder with an internal rectilinear surface, which is substantially parallel to the plane of the tongue when the cover is placed on the head of the razor and with an external convex surface. In this embodiment, it is the internal rectilinear surface which engages with the tongue and which communicates to it the force necessary for its rupture when removing the cover. However, the convex surface allows the fitting of the cover on the head of the razor despite the presence of the tongue; because of the convex shape, there is an action progressive mechanics on the tongue which causes it to bend without breaking.
De préférence l'épaulement avec surface convexe externe et surface rectiligne interne constitue le bord longitudinal du capot protecteur.Preferably the shoulder with external convex surface and internal rectilinear surface constitutes the longitudinal edge of the cover protective.
De manière à ne pas altérer l'esthétique de la tête du rasoir, de préférence la languette se trouve sur la face inférieure de la tête du rasoir.In order not to alter the aesthetics of the razor head, preferably the tab is on the underside of the head of the Shaver.
S'agissant plus particulièrement d'un rasoir jetable constitué d'éléments obtenus par moulage ou injection de matière plastique, la pièce apte à être brisée lors du premier retrait du capot protecteur fait partie intégrante d'un desdits éléments de la tête.More specifically, a disposable razor made of elements obtained by molding or injection of plastic, the part capable of being broken during the first removal of the protective cover made integral part of one of said elements of the head.
Selon une autre variante de réalisation de l'invention, la pièce faisant office de témoin sonore de premier usage est une languette fixée sur la face intérieure du capot protecteur et venant en prise avec une partie de la tête du rasoir lors du retrait dudit capot.According to another alternative embodiment of the invention, the part acting as first-time audible indicator is a fixed tab on the inside of the protective cover and engaging with a part of the razor head when removing said cover.
De plus il peut être possible de disposer non pas une mais plusieurs languettes aptes à être brisées lors du premier retrait du capot protecteur, lesdites pièces étant notamment décalées les unes par rapport aux autres dans la direction de déplacement du capot protecteur par rapport à la tête du rasoir lors du retrait dudit capot de manière à provoquer une succession de bruits de rupture.In addition it may be possible to have not one but several tabs capable of being broken during the first removal of the cover protector, said parts being in particular offset by one relative to others in the direction of movement of the protective cover relative to the razor head when removing said cover so as to cause a succession of breaking noises.
S'agissant d'un système de rasoir à têtes jetables, éventuellement non pourvu d'un capot protecteur, dans lequel système chaque tête jetable est insérée dans un logement protecteur dans lequel ladite tête s'emboíte de manière amovible, du type géneral connu du brevet US-A-4,285,428 selon la revendication 9 ledit système comporte au moins une languette apte à être brisée lors du premier retrait de la tête hors de son logement, dans les mêmes conditions que ci-dessus.Being a razor system with disposable heads, possibly not provided with a protective cover, in which system each disposable head is inserted into a protective housing in which said head removably fits, of the general type known from US-A-4,285,428 according to claim 9 said system comprises at least one tab capable of being broken during first removal of the head from its housing, in the same conditions as above.
La présente invention sera mieux comprise à la lecture de la description qui va être faite d'un mode préféré de réalisation d'un rasoir jetable à témoin sonore de premier usage , illustré par le dessin annexé dans lequel la figure unique est une représentation schématique en coupe partielle dudit rasoir.The present invention will be better understood on reading the description which will be given of a preferred embodiment of a razor disposable with first-time audible indicator, illustrated by the attached drawing in which the single figure is a schematic sectional representation partial of said razor.
Le rasoir 1 comporte une tête 2 et un manche non représenté,
ladite tête 2 étant équipée d'une lame de coupe 3. S'agissant d'un rasoir
jetable, cette tête 2 est constituée de divers éléments obtenus par
injection ou moulage de matière plastique, par exemple de polystyrène
et assemblés par tout moyen approprié.The razor 1 comprises a
Le rasoir 1 comporte également un capot protecteur 4 qui
enveloppe toute la partie avant 5 de la tête 2 et dont la fonction est de
protéger la lame de coupe 3. Ce capot protecteur 4 est constitué pour
venir s'emboíter, de manière amovible, sur ladite partie avant 5. Son
maintien en position , dans la configuration illustrée, est obtenu par tout
moyen connu, par exemple grâce à la présence de tétons, pratiqués par
poinçonnage thermique sur le capot protecteur, lesdits tétons venant
s'appliquer dans des parties en creux de la tête du rasoir, créant ainsi une
certaine résistance pour le retrait du capot protecteur 4.The razor 1 also includes a protective cover 4 which
wraps the
Selon la caractéristique de l'invention, la tête 2 du rasoir 1 ,
incluant son capot protecteur 4, comporte de plus une languette apte à
être brisée lors du premier retrait du capot protecteur 4. Cette pièce
constitue un témoin sonore, garantissant que le capot 4 n'a jamais été
enlevé depuis sa pose initiale sur la tête 2.According to the characteristic of the invention, the
Dans l'exemple illustré, cette languette 6, fait partie intégrante
d'un des éléments 7 obtenus par injection ou moulage d'une matière
plastique. Cette languette 6 est disposée sous la face inférieure 2a de la
tête 2, sensiblement perpendiculaire à ladite face 2a.In the example illustrated, this
Le bord longitudinal 4a du capot protecteur 4 qui est destiné à
être placé au niveau de ladite face inférieure 2a de la tête 2 est terminé
par un épaulement 8 tourné vers l'intérieur du capot protecteur 4. Cet
épaulement 8 a une forme en quart d'olive, avec une surface convexe
externe 8a et une surface rectiligne interne 8b.The
Lors du premier montage du capot protecteur 4 sur la tête 2,
c'est la surface convexe 8a qui vient s'appliquer sur la languette 6. Du
fait de la courbure de cette surface convexe 8a, la languette subit une
force progressive qui la fait plier , sans se rompre. Par contre lors du
retrait du capot protecteur 4 par l'utilisateur , c'est la surface rectiligne
interne 8b qui s'applique sur la languette 6 appliquant une force
instantanée importante qui est suffisante pour briser la languette 6 et
obtenir le signal sonore significatif , selon l'invention, du premier usage.During the first mounting of the protective cover 4 on the
Pour obtenir une rupture nette, de manière fiable, la surface
rectiligne interne 8b est de préférence parallèle au plan de la languette 6;
de plus l'épaisseur de la languette 6 doit être suffisamment faible pour
que la résistance mécanique nécessaire à obtenir la rupture soit
compatible avec la force habituellement mise en oeuvre par l'utilisateur
pour retirer le capot protecteur 4. To get a clean break, reliably, the rectilinear inner surface 8 b is preferably parallel to the plane of the
La présente invention n'est pas limitée au mode précis de
réalisation qui vient d'être décrit à titre d'exemple non exhaustif. On
pourrait en effet disposer sur la face inférieure 2a de la tête 2 une
succession de languettes 6, décalées les unes aux autres dans le sens de
déplacement de la surface interne 8b lors du retrait du capot 4 , induisant
une succession de ruptures et donc un effet sonore en cascade.The present invention is not limited to the precise embodiment which has just been described by way of non-exhaustive example. We could indeed have on the
Par ailleurs il serait possible de fixer la languette apte à être brisée non plus sur la tête du rasoir mais sur le capot proprement dit. Dans ce cas c'est une partie de la tête qui ferait office de surface d'appui pour obtenir la rupture de ladite languette. Cette alternative serait cependant plus complexe à réaliser par rapport à l'exemple précité.In addition it would be possible to fix the tongue capable of being broken no longer on the razor head but on the hood itself. In this case it is a part of the head which would act as a support surface for obtain the rupture of said tongue. This alternative would however more complex to perform compared to the above example.
Dans ce qui vient d'être décrit, le retrait du capot protecteur 4 s'effectue selon une direction illustrée par la flèche F sur la figure. D'autres formes de capots protecteurs peuvent être mises en oeuvre, selon l'invention, y compris ceux dont le retrait s'effectue dans une direction longitudinale par rapport à la direction des lames de coupe, direction qui est perpendiculaire au plan de la coupe de la figure unique. Dans ce cas bien sûr la surface d'appui ne sera plus selon une direction longitudinale comme précitée mais selon une direction transversale.In what has just been described, the removal of the protective cover 4 takes place in a direction illustrated by the arrow F in the figure. Other forms of protective covers can be implemented, according to the invention, including those whose removal takes place in a longitudinal direction relative to the direction of the cutting blades, direction which is perpendicular to the plane of the section of the single figure. In this case of course the bearing surface will no longer be in a direction longitudinal as above but in a transverse direction.
Enfin, la présente invention s'applique non seulement aux rasoirs jetables comme décrits ci-dessus mais également aux systèmes de rasage comprenant un rasoir à têtes jetables, lesdites têtes étant vendues en lots et insérées dans des logements protecteurs, chaque tête étant emboítée dans le logement correspondant. Lorsqu'il veut utiliser une nouvelle tête, l'utilisateur présente le rasoir dépourvue de tête face au logement, introduit dans la tête les moyens de solidarisation et exerce une traction de manière à faire sortir la tête du logement dans lequel elle est emboítée. Eventuellement il peut , s'il le souhaite, replacer après usage, la tête dans son logement en procédant de manière inverse à ce qui vient d'être décrit. Selon l'invention, le système de rasoir comporte une languette apte à être brisée lors du premier retrait de la tête hors de son logement. Cette languette est fixée soit dans le logement soit sur la tête dans des conditions similaires à ce qui a été décrit dans l'exemple ci-dessus, c'est-à-dire venant en prise respectivement soit avec une partie de la tête soit avec une partie du logement de manière à être brisée lors du premier retrait de la tête hors de son logement. Ainsi lorsque l'utilisateur retire pour la première fois, après acquisition , la tête de son logement, il perçoit l'effet sonore recherché qui lui garantit qu'il s'agit d'un premier usage pour la tête qu'il va utiliser.Finally, the present invention applies not only to razors disposable as described above but also to the shaving comprising a razor with disposable heads, said heads being sold in batches and inserted in protective housings, each head being nested in the corresponding housing. When he wants to use a new head, the user presents the razor without head facing the housing, introduces in the head the means of attachment and exercises a pull so as to bring the head out of the housing in which it is fitted. Possibly he can, if he wishes, replace after use, the head in its housing by proceeding in reverse which has just been described. According to the invention, the razor system comprises a tongue capable of being broken during the first removal of the head from its housing. This tab is fixed either in the housing or on the head under conditions similar to what was described in the example above, that is to say respectively engaging either with a part of the head either with part of the housing so as to be broken during the first removal of the head from its housing. So when the user removes the head for the first time after acquisition housing, he perceives the desired sound effect which guarantees him that it is first use for the head he will use
