Unitary shaving razor cartridge

Abstract

The present invention relates to a shaving razor cartridge, comprising: one or more curved razor blades, an upper housing comprising an exposing portion for exposing the edges of the razor blades to the outside, and a guard; and a lower housing coupled to the upper housing, having a blade mounting portion for supporting the razor blades, wherein the bottoms of said one or more razor blades are supported at both ends and the center of the blade mounting portion, and both ends of said razor blades have notches such that the tops of the razor blades are supported and vertically connected to both ends of the upper housing. As the notches are formed at both ends of the razor blades to enable the razor blades to be accommodated in the space between the blade mounting portion and the upper housing, the necessity of a clip for fixing razor blades is eliminated, and the deformation of the razor blades can be prevented, thus making products slim and small-sized, and enabling the automatic assembly of cartridges of a variety of shapes and reducing production costs.

Description

Technical field [0001] The invention relates to a blade holder for wet razors. A wet razor is composed of a handle and a blade frame. Generally, the blade frame includes more than one blade and a protective sheet in a plastic housing, and supports the blade in a predetermined direction, guides the hair in the predetermined direction when shaving hair, so as to prevent the deformation of the blade, and has Gentle feeling. Background technique [0002] The basic function of a razor is to use a blade to shave body hair such as hair on the body or beard.

Problems solved by technology

Therefore, the position of the blade subjected to force in a predetermined direction changes during shaving, thereby degrading the shaving performance

[0010] Third, the part where the jig and the blade of the metal material are in contact with the face is the most damaged part when shaving, and due to the characteristics of a wet razor, it cannot prevent the blade from rusting due to moisture
