Embodiment Construction

[0020] A shaving head according to the invention is indicated with reference 1 in the figures.

[0021] The shaver head 1 comprises a guard 2 (hereinafter referred to as a plate guard), a blade assembly 3 mounted and fixed to the guard, and a plate rear cover 4 with a latch 5 for connection to a handle end.

[0022] The plate guard 2 has a substantially rectangular shape, comprising a flat base portion 6 and a peripheral wall 7 protruding substantially perpendicularly from the base portion 6 .

[0023] The peripheral wall 7 and the base portion 6 together define an interior space 8 in which the blade assembly 3 is received during installation of the shaving head, as described below.

[0024] The plate guard 2 is provided with a rectangular hole 9 extending along the base portion 6 so as to define a guard bar 10 in a straight peripheral wall portion 11 on the side opposite the base portion 6 .

[0025] The base portion 6 has a substantially planar lower or inner surface 12 fac...

Abstract

A method of producing a razor head (1) including a first plastic member (2) and a second plastic member (4), comprising the step of laser welding said first plastic member (2) to said second plastic member (4).

Description

technical field [0001] This invention relates to safety razors and, more particularly, to a method of making a razor and a shaving head. Background technique [0002] Ferraro's patent US5,276,967 discloses a wet shaver assembly comprising a base, a cover, two blades and a spacer. The cover includes retaining pins that pass through a series of co-linear holes in the blade and spacer and are received by these holes in a base sized such that the pins can be snapped into and then Can't quit. These pins are sized such that the parts of such an assembly are securely sandwiched between the cover and base once the blade is installed. [0003] A disadvantage of such a structure is that it is not completely secure. Sometimes these pins are not sized to ensure a secure fit between the base and cover. There is a risk that the base and cover will separate, allowing the blades to unravel. Contents of the invention [0004] The object of the present invention is to provide a safe sh...
