Abstract

THE RAZOR IS OF THE DISPOSABLE TYPE AND CONSISTS OF A SINGLE-PIECE SHAPED HANDLE WITH A PROTECTION BAR 23 AND A BLADE COVER 27, THIS PROTECTION BAR BEING SHAPED ON THE UPPER END OF THE HANDLE. A BLADE 31 IS RIVETED TO THE BLADE COVER INSIDE A SPACE OPENING DOWN AND BOUNDED BETWEEN THE REAR FACE OF THE HANDLE, THE BLADE COVER 27 AND TWO SIDE PORTIONS 25 WHICH ARE AN INTEGRAL PART OF THE BLADE COVER AND OF THE PROTECTION BAR.

Description

-1- This invention relates to razors, and in particular to

disposable razors A disposable razor

  has a handle, usually made of plas-

  tick, and a blade block containing one or more la-

  mes, the handle like the blade block being designed to be both thrown away when the user finds that the

  razor no longer allows him to shave properly.

  We know, for example from the patent GB-A-

  2.050 912, a razor comprising a handle, a shaving blade having a cutting edge, a blade cover, a protective bar spaced from the blade cover so as to delimit an interval between them, interval through which

  protrudes the cutting edge of the blade, and elements la-

  sides arranged along opposite sides of the blade and forming an integral part of the protection bar and

of the handle.

  For a razor of this type, there is a requirement

  this construction holding in the simplification of the o

  the task of mounting and fixing a blade in the

Shaver.

  According to the present invention, this is achieved

  in that the blade cover is an integral part of the elements

  side elements and is permanently attached directly to the blade cover. According to a preferred version of the invention, the rear face of the handle adjacent to the protective bar, the faces directed towards the inside of the lateral elements and, when the razor is directed upwards, the underside of the cover delimits a space which opens down onto the rest of the handle and into which is inserted

the blade.

  A razor construction in accordance with the invention

  tion will now be described only by way of example

  with reference to the accompanying drawings in which:

  Figure 1 is a side view of a razor

  form of the invention; Figure 2 is a front view of the razor of Figure 1, where the front is the side directed towards the one that shaves when in use Figure 3 is a section of Figure 2 along line III- III but without the blade Figure 4 is a section on the line IV-IV of Figure 2; Figure 5 is a view of the shaving head seen in the direction of the arrow E in Figure 3 Figure 6 is a sectional view of the shaving head on a larger scale; and Figure 7 is a view corresponding to that

  of Figure 6, of a modified razor.

  The razor shown in the drawings comprises a handle 11 having at one end a shaving head 12

  forming an integral part of the handle by molding of material

re plastic.

  The handle, which has a trough shape over its entire length, comprises a portion 13 intended to be taken in hand, and which is connected, at one end, to the head by a portion in the form of a curved neck. the portion intended to be grasped by the hand, the trough 15

  is divided by a rib 16 which protrudes longitu-

  dinalically in its center, and transverse ribs 17 protrude at intervals spaced from one another between the central rib 16 and the sides 18, 19 of the trough The front face of the handle is formed with

  transverse edges 20 to help the user to

on the handle.

  As shown in Figures 2 and 6, the

  edges 20 placed on the front of the handle form a ner-

  vure 21 along the handle, this rib having

  flat sides separated by an interval such that it

  fit tightly in trough 15 on the back side of the next adjacent handle when the sleeves are assembled with the front of one against the back of the other This tight fit will allow the sleeves to fit together and to join each other until

  that they are drawn by the user can be separated.

  The depth of the trough decreases on the neck portion 14 of the handle which joins the portion gripped by the

  hand 13 to head 12 of the razor, this portion being in-

  curved in the concave direction if we look at it from the a-

  front of the razor To strengthen it, the front side of the

  neck portion consists of three long ribs

  tudinal spaced apart and parallel to each other 22.

  The razor head, which is an integral part

  of the neck, in the form of a rectangular frame One side al-

  along this frame is immediately at the end of the neck portion of the handle and constitutes a protective bar. Two sides 24, 25 of the frame extend towards

4 2545751

  the rear from the opposite ends of the protective bar and, with a fourth side 26, support a

  cap-shaped portion inside the frame,

  tion that serves as a blade cover 27 The underside of the blade cover is essentially flat and forms a

  platform 28 receiving the blade Four cylindrical studs

  ques 30 protrude from the perpendicular platform-

  lie to it to pass through openings of a

blade 31.

  Platform 28 receiving the cover sheet

  me 27 is spaced from the protection bar, both

  in the plane of this platform and in a perpetual sense

diculaire to this platform.

  The blade 31, which is shown in Figure 4, is provided with openings 32 corresponding to the studs on the underside of the blade cover The blade is placed in position on the studs of the blade support platform and fixed in position by heads welded on the studs, or by riveting these studs to form heads whose dimension is slightly greater than the openings of

the blade.

  As shown in Figure 6, the edge of the blade 31 a is fully housed in the bordered opening

  by the protection bar, the blade cover and the sides-

  of the frame In addition, the edge of the blade is not supported

over its entire length.

  The positioning of the blade on the studs 30 and the riveting of the studs is facilitated by the fact that

  the space in which the blade is housed is delimited

  ted by the rear face of the handle 11, the blade cover 27 -5-

  and the sides 24, 25 and opens downwards (in the po-

  upright position of the razor) without interfering with the movement

cementation of a blade in this space.

  Although the razor has been depicted as

  holding a single blade, its dimensions could be adapted so that it receives two blades spaced from one another and stepped, both supported on

  studs protruding from the underside of the neck

  blade. At the end of the handle opposite the head, a

  slot 33 is practiced and helps to put the handle in place

  this when attached to a display panel or a wall

  quet. In the modified version of the razor shown in Figure 7, the blade cover 127 has a fin 135 which is an integral part thereof and which is articulated on its free external side, this fin being provided with four

  openings 136 which adapt to the four studs 130.

  Consequently, when the blade has been lodged on the

  jons 130, the fin is folded so as to rest against the blade, with the studs projecting through the openings 136 of the fin The studs are then welded or riveted to lock the fin and the blade in position The fin then serves as a support over the length

from the edge of the blade.
