Razor cartridge and the razor using the same

The present invention relates to a razor cartridge and a razor using the same, and more particularly, to a razor cartridge and a razor using the same by installing a guard adjacent to the razor blade to increase the shaving effect.

The basic function of the razor is to use a razor blade (blade) to cut and remove hairs, such as hair and whiskers, that have grown on your body. To this end, a lot of research on the function of the razor blade has been progressed in recent years, studies on the structure for improving the shaving performance by assisting the function of the razor blade as well as the razor blades are actively underway.

An example is a guard installed adjacent to a razor blade. The guard acts on the skin before the hair is cut with the razor blade, so it can be cut and raised.

This guard structure is described in US Pat. No. 6,651,342, which will be described with reference to FIG.

In Fig. 1, reference numeral 18 denotes a razor blade, and reference numeral 20 denotes a guard.

As described above, the conventional guard has a configuration in which a plurality of bars are installed in parallel as a straight bar.

However, the above configuration has the following problems.

First, since it has a simple straight bar shape, there is no consideration of a fine skin shape, so the compression effect on the skin is reduced.

Second, the bar shape is elongated in the direction of the blade, the elasticity is dropped so that the user does not feel a soft feeling can feel uncomfortable.

Third, it is difficult to independently control the hairs that appear out of order in the shape of the bar.

In order to solve the above problems, an object of the present invention is to provide a razor cartridge and a razor that have an excellent effect on skin compression and can give a soft feeling when used.

In order to achieve the above object, the present invention comprises a housing, a razor blade installed in the housing and having an edge for cutting body hair, and a guard adjacent to the edge of the razor blade, the guard edge of the razor blade Provided is a razor cartridge having a base plate adjacent to and a plate-shaped elastic protrusion protruding from the base plate and narrowing upwards.

The guard includes a plurality of protrusions in which the elastic protrusions are arranged in the lateral direction, and a plurality of the protrusions are arranged back and forth. In addition, it is more preferable that the elastic protrusions of the adjacent protrusions are staggered from each other.

In addition, when viewed from the front, the elastic protrusions are smaller in the horizontal length toward the top, the protrusions are preferably arc-shaped.

The bottom plate may have a curved surface facing downward toward the end of the housing when viewed from the side.

In addition, the elastic protrusions of the protrusion rows may be configured such that the height becomes lower toward the end of the housing.

On the other hand, according to the present invention, it comprises a housing, a razor blade installed in the housing and having an edge for cutting the hair, a razor blade cartridge having a guard adjacent to the edge of the razor blade, and a handle for supporting the razor blade cartridge, The guard provides a razor having a bottom plate formed in the direction of the blade and a plate-shaped elastic protrusion protruding from the bottom plate and narrowing upward.

According to the present invention is configured to correspond to the fine skin shape has an advantage of excellent skin compression effect.

In addition, the elasticity is increased to give the user a soft feeling when shaving.

In addition, the shaving performance is greatly improved by controlling every hair that is disordered.

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

2 and 3, the basic configuration of the razor cartridge according to the present invention will be described. In addition, in FIG. 2, the direction viewed from the A direction is defined as the front side, and the direction viewed from the B direction is defined as the side surface.

The razor cartridge 100 according to the present embodiment includes a housing 110, a guard 120, a lubrication band 130, a razor blade 140, and a coupling protrusion 150.

The housing 110 forms the appearance of the razor cartridge and provides a structure in which a razor blade can be installed. In addition, the housing 110 is provided with a guard 120, a lubrication band 130, a coupling protrusion 150 and the like. In this embodiment, the material of the housing 110 is made of synthetic resin, but may be provided with other materials such as wood or metal, if necessary.

The guard 120 is formed adjacent to the edge of the razor blade, and serves to raise the hair on the skin in contact with the shave so that the razor blade can be easily cut.

The lubrication band 130 is installed on the opposite side of the edge of the blade 140 for skin moisturizing and soothing effect. The lubrication band 130 may contain a chamomile, olive, allatoin components so that the user can feel more fresh after shaving.

The razor blade 140 serves to cut the hair growing in the body, such as hair or beard. One surface of the razor blade 140 is formed with an edge 142, the end of which is sharply processed. The edge 142 may be coated with various coatings to improve performance. Hair is cut as the edge 142 moves.

With reference to FIG. 4, the installation of the razor blade 140 will be described. Figure 4 shows a portion cut off the middle portion of the razor cartridge according to this embodiment.

The razor blade 140 is configured in a bent shape, is inserted between the fixing projections 132 formed in the housing 110 is installed. As a result, a portion of the blade 140 is fixed by the fixing protrusion 132, the bent portion is to be in direct contact with the user's skin as shown in Figs.

One blade may be installed, but a plurality of blades are preferably installed to improve shaving performance. In the present embodiment, six razor blades are installed.

The fixing protrusion 132 is formed at both ends and the middle portion of the housing 110. Thus, both ends and the middle portion of the blade 140 is supported.

The guard 120 serves to pull up the skin before the hair is cut by the razor blade 140 to raise the hair.

Referring to FIG. 6, in the present embodiment, the guard 120 is formed of a rubber material having elasticity, and includes a bottom plate 126 and an elastic protrusion 122.

The elastic protrusions 122 are configured to protrude so that the area becomes narrower when viewed from the front.

For example, referring to FIGS. 7 and 8, the elastic protrusions 122 are formed in a triangular shape having a curved end when viewed from the front. In addition, the elastic protrusion 122 has a plate shape with a constant thickness when viewed from the side.

In the present embodiment, the elastic protrusion 122 is formed in a triangular shape of 0.6 ~ 1mm in width, 0.3 ~ 0.6mm in height, 0.2 ~ 0.5mm in thickness.

Even if the same force is given in the above-described shape, the elastic protrusions 122 may be bent more smoothly.

On the other hand, a plurality of elastic protrusions 122 are gathered to form a series of protrusions (124). In detail, when viewed from the front, a plurality of elastic protrusions 122 are connected in parallel to each other to form a protrusion line 124.

In addition, a plurality of the protrusion rows 124 are arranged back and forth to form the guard 120. It is preferable that three to fifteen rows of the protrusions are arranged. In the present embodiment, eight protrusions 124 are arranged to form the guard 120.

Each of the elastic protrusions 122 in the protrusion line 124 is individually acting on the skin can be independently controlled to the disorderly hair growth.

Next, with reference to FIG. 3, the shape of a processus | protrusion line is demonstrated.

According to the present embodiment, the projection lines 124 have an arc shape. Specifically, the center portion of the projection line 124 has a shape that is far from the edge 142 of the blade adjacent to both ends.

Due to such a shape, the guard 120 is more compressed on the user's skin when shaving, thereby improving shaving performance.

Referring to FIG. 7, the elastic protrusions 122 of adjacent front and rear protrusion rows in the plurality of protrusion rows 124 are alternately arranged. That is, the elastic protrusions of one of the protrusion lines are disposed between the elastic protrusions of the front and rear protrusion lines.

Due to this structure, the elastic protrusion 122 is prevented from colliding with the elastic protrusions of immediately adjacent protrusion lines when the elastic protrusions 122 are elastically deformed and bent. Therefore, it can be bent more smoothly so that the user can feel a softer when shaving.

The shape of the elastic protrusions 122 may be modified into other shapes. That is, referring to FIGS. 9 and 10, the elastic protrusions have a trapezoidal shape. In addition, referring to Figure 11 and Figure 12, it is preferable to have a constant interval between the trapezoidal elastic projections.

5 and 6, the bottom plate 126 preferably has a curved shape that is lowered toward the end of the housing 110. This shape makes the skin feel softer when shaving, and the pressing force on the skin is increased.

On the other hand, it is also preferable that the base plate 126 has a planar shape and the height of the elastic protrusions is made smaller as the plurality of protrusion rows toward the ends of the housing 110. This can improve the user's feel when shaving and reduce the manufacturing cost.

The coupling protrusion 150 is a portion that is coupled to the handle (not shown).

The shaver according to the present invention allows the shaver cartridge to be rotated at an angle with respect to the handle to smoothly shave.

Next, the operation of the razor cartridge and the razor according to the present invention will be described.

The user grabs the handle and makes the razor cartridge 100 come into contact with the skin, and then pushes the guard forward. At this time, the guard 120 pulls the skin upright to help the body hair can be cut by the razor blade 140.

Specifically, the elastic protrusions 122 of the guard 120 are elastically deformed and bent in contact with the skin to compress the skin. The elastic protrusion 122 according to the present invention is easily bent because the area becomes smaller toward the top. In addition, since the elastic protrusions of the front and rear protrusion rows 124 are alternately arranged, the elastic protrusions can be bent more greatly, thereby improving the compressive force.

Then, the hair is cut by the edge 142 of the blade. Then, the lubrication band is to moisturize and soothe the skin.
