Definitions
- the present invention relates to a razor, in particular disposable or disposable head, the blade or blades are protected, during acquisition by the user, by a cover or a protective housing.
- a cover or a protective housing When buying a razor, the user cannot be sure that it has not been used before or that the blade has not been damaged in any way. This uncertainty is all the more annoying 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 on average.
- Certainly most disposable razors are provided with a protective cover which fits over the head of the razor to protect the cutting blade (s).
- 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 head of the razor after each use.
- disposable heads which are inserted in protective housings, insofar as it is possible to reposition the disposable head after use in its housing.
- the razor of the invention whose head, in known manner, is provided with a protective member in which it removably fits to protect the cutting blade or blades before and possibly after use and which comprises a part capable of being broken on the occasion of the first removal of the protective cover.
- 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 or 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 body) and it is the usual gesture of separation of the two elements which causes the rupture of the tongue.
- the noise caused by the rupture of the tongue constitutes an audible indicator, confirming to the user that the protective member which was placed during the mounting of the razor has not yet been removed and therefore that the use it is going to to do is a first use.
- the tongue is fixed on the head of the razor to protect the cutting blade (s) before and after use
- the tongue is fixed on the head of the razor and engages with part of the protective cover when the latter is removed.
- 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 the latter the force necessary for its rupture when the cover is removed.
- the convex surface allows the fitting of the cover on the head of the razor despite the presence of the tongue; in fact due to the convex shape, there is a progressive mechanical action on the tongue which causes the latter to bend without breaking.
- the shoulder with external convex surface and internal rectilinear surface constitutes the longitudinal edge of the protective cover.
- the tab is on the underside of the razor head.
- the part capable of being broken during the first removal of the protective cover forms an integral part of one of said elements of the head.
- the part serving as a first-use sound indicator is a fixed tongue on the inner face of the protective cover and engaging with part of the razor head when removing said cover.
- the said system comprises at least one tab capable of being broken during the first removal of the head from its housing, under 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.
- this head 2 is made up of various elements obtained by injection or molding of material plastic, for example polystyrene and assembled by any suitable means.
- the razor 1 also comprises a protective cover 4 which envelops the entire front part 5 of the head 2 and whose function is to protect the cutting blade 3.
- This protective cover 4 is made to come and fit, in a removable manner, 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 to be applied in hollow parts of the razor head, thus creating a certain resistance for the withdrawal of the protective cover 4.
- the head 2 of the razor 1, including its protective cover 4 further comprises a tongue capable of being broken during the first removal of the protective cover 4.
- This piece constitutes an audible indicator, guaranteeing that the cover 4 has never been removed since it was first placed on 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 2a of the head 2, substantially perpendicular to said face 2a.
- the longitudinal edge 4a of the protective cover 4 which is intended to be placed at the level of said lower face 2a of the head 2 is terminated by a shoulder 8 turned towards the inside of the protective cover 4.
- This shoulder 8 has a quarter shape. olive, with an external convex surface 8a and an internal rectilinear surface 8t).
- the convex surface 8a which is applied to the tongue 6. Due to the curvature of this convex surface 8a, the tongue undergoes a progressive force which makes it bend, without breaking.
- the protective cover 4 is removed by the user, it is the internal rectilinear surface 8t_ which is applied to the tongue 6 applying a large instantaneous force which is sufficient to break the tongue 6 and obtain the significant sound signal, according to the invention, the first use.
- the internal rectilinear surface 8b 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 2a of the head 2 a succession of tongues 6, offset to each other in the direction of movement of the internal surface 8b when removing the cover 4, inducing a succession of ruptures and therefore a cascading sound effect.
- the protective cover 4 is removed 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 is carried out in a longitudinal direction relative to the direction of the cutting blades, direction which is perpendicular to the plane of the cut. of the single figure. In this case of course the bearing surface will no longer be in a longitudinal direction as mentioned above but in a transverse direction.
- the present invention applies not only to disposable razors as described above but also to shaving systems comprising a razor with disposable heads, said heads being sold in batches and inserted in protective housings, each head being fitted into the corresponding accommodation.
- 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 has been described in the example above, that is to say respectively engaging either with a part of the head or 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, the head from his housing, he perceives the desired sound effect which guarantees him that it is a first use for the head he is going to use.
