Description

Elastic razor cartridge

The present invention relates to a razor cartridge, and more particularly to an elastic razor cartridge provided with a soap capable of enhancing cleaning and lubricating action, thereby improving the structure to maintain a soft shaving feeling.

In wet shaver, various additives are used to improve the function when shaving. In particular, lubrication bands containing lubricating materials are often installed to give a soft feeling. These lubricating bands contain lubricating materials and come in a form in which lubricating materials melt when water comes in contact.

However, in women's shaver, where softness is more emphasized, lubrication bands are not enough, and soap is sometimes installed. Direct installation of these soaps has the disadvantage of widening the area occupied by the soap, but the washing and lubricating action of the soap is superior to the lubrication band, so the use of the shaver for women is increasing.

Referring to FIG. 1 as a razor using such a soap, although the soap 28 is provided in US Patent Application Publication No. 2006/0196054 or the like, since the soap is large and protrudes above the blade, the solid soap protrudes during actual shaving. Rather, the user may feel uncomfortable.

In addition, there is a problem that the solid soap does not adhere to the skin continuously due to the bending of the armpits, legs, arms, etc., does not continuously produce bubbles and give a soft feeling.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an elastic razor cartridge in which soap is installed, which can give a soft feeling as much as possible according to the curvature of the body.

In order to achieve the above object, the present invention provides a razor cartridge comprising a soap, the razor cartridge, a blade for cutting the hair; A frame accommodating the blade; And a soap coupled to the frame to clean and lubricate, wherein the soap is elastically coupled to the frame such that the soap is pressed by the skin and then restored to its original shape.

The frame includes a plastic frame accommodating the blade and a rubber frame accommodating the soap, and the soap may elastically move up and down by elastic action of the rubber frame.

The soap may be coupled to a soap carrier for accommodating the soap, and an elastic hole may be provided in the rubber frame to couple the soap carrier to the elastic hole.

The elastic hole preferably includes an elastic leg that is formed to a predetermined thickness on the periphery of the soap carrier and the outer periphery of the peripheral part and is coupled to the rubber frame.

A plurality of protrusions may be formed in the soap carrier, and the soap may be coupled to each other by forming grooves corresponding to the plurality of protrusions.

The frame is provided with a spring or a plate-like elastic body, the soap can be elastically moved up and down by the spring or plate-like elastic body.

The soap may be provided at the rear of the blade, and a lubrication band containing a lubricating material may be provided at the front of the blade.

According to the present invention, it is possible to provide an elastic razor cartridge which minimizes skin irritation and maximizes the soft feeling.

In addition, it is possible to provide an elastic razor cartridge that closely adheres to the curvature of the body to give a soap bubble, thereby effectively increasing the lubrication action of the soap.

6A to 8B are explanatory views for explaining the principle of operation of the elastic razor cartridge according to the present invention;

The configuration and operation of the embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 2, the elastic razor cartridge according to the present invention includes a frame 100, a blade 200, a lubrication band 300, and a soap 400.

The frame 100 constitutes an external shape of the razor cartridge and is a place where various components such as a blade, a lubrication band, and soap are mounted. The frame 100 may be formed in one piece, or may be configured by combining several frames.

In the present embodiment, mainly for the female razor cartridge, the frame is formed in an oval curved shape as a whole.

Referring to FIG. 3, the frame includes a body frame 120, an elastic frame 130, and a blade frame 140.

The body frame 120 is formed of a plastic material, the blade coupling portion 122 is coupled to the blade frame 140 and the soap coupling portion 124 is coupled to the soap 400 is formed. That is, the blade frame portion 140 is coupled to the blade coupling portion 122 is formed in a generally rectangular shape in the front portion of the main body frame 120, the soap coupling portion 124 formed in an oval shape in the rear portion is soap 400 is combined.

The blade frame 140 is formed of a plastic material, the lubrication band coupling portion 144 to which the lubrication band 400 is coupled to the front is formed, the blade slot 142 is formed in the rear blade is inserted. Preferably, a plurality of blades is provided in parallel, and in this embodiment, three blades are provided.

As described above, according to the present invention, the main body frame 120 and the blade frame 140 are separately provided, and the blade frame 140 is provided with a lubrication band so that assembly is easier than installing all parts directly to the main body frame. And the design can be simplified to improve productivity.

That is, when all parts are assembled in the main body frame, productivity is decreased because other parts cannot be assembled until one part is assembled, but according to the present invention, since each part is modularly installed in the main body frame, parallel assembly production is performed. This can be advantageous in assembling and replacing parts.

The elastic frame 130 is formed of a synthetic resin such as rubber or elastomer having elasticity, is coupled to the upper body frame 120.

4 and 5, the elastic frame 130 is provided with an elastic hole 132. That is, the elastic hole 132 is where the soap is coupled, is formed by the peripheral portion 134 and the elastic leg 136.

On the other hand, the soap 400 is provided with a solid soap, accommodated in the soap carrier 420 is installed.

The soap carrier 420 is formed to correspond to the soap shape, a plurality of protrusions 422 are formed therein. In addition, the soap 400 has a groove corresponding to the protrusion 422 is easily coupled to the soap carrier.

The soap carrier is inserted into the elastic hole 132 of the elastic frame 130 and elastically coupled.

Referring to FIG. 5, the outer circumference of the soap carrier is wrapped by the peripheral part 134, and the peripheral part 134 is connected to the elastic frame 130 by the elastic leg 136.

The elastic leg 136 serves to substantially move the soap 400 up and down, and is formed relatively thinner than other portions of the elastic frame 130. The plurality of elastic legs 136 are provided along the periphery 134 to support the periphery 134 to move up and down elastically.

The peripheral portion 134 and the elastic leg 136 may be provided with a material having a greater elasticity than other portions of the elastic frame 130.

Next, the operation of the elastic razor cartridge according to the present invention will be described with reference to FIGS. 6A and 6B.

In the initial state, the soap 400 protrudes considerably more than the blade 200 as shown in FIG. 6A.

When the shaving starts, the lubrication band 300 is first in contact with the skin, and the lubricant is discharged from the lubrication band to make the skin slippery. Thereafter, the hair is cut by the blade 200, and the soap 400 behind the blade comes into contact with the skin.

Then, as shown in Figure 6b, by the pressure of the skin soap enters as the elastic leg is deformed. As a result, the soap is in close contact with the skin and does not give a feeling of being caught, so that the washing and lubricating action is smooth.

When the razor cartridge is removed from the skin, the soap is restored to its original state by the elastic legs and is again maintained in the protruding state as shown in FIG. 6A.

Referring to FIGS. 7A and 7B, the soap 400 may be supported by a spring 500 in a frame. Referring to FIGS. 8A and 8B, the soap 400 may include a leaf spring or a plate-shaped elastic body 510. Can be supported by.

Although the above has been described with reference to the embodiments of the present invention, those skilled in the art may variously modify and modify the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. It will be appreciated that it can be changed.
