Description

Razor Cartridge and Manufacturing Method thereof

The present disclosure relates to a razor cartridge and a method of manufacturing the razor cartridge.

The content described in this section merely provides background information for the present disclosure and does not constitute the prior art.

A razor cartridge includes a shaving blade having a cutting edge, a blade housing to receive the shaving blade, and a clip to hold the shaving blade to the blade housing do.

The clip generally has the shape of an elongated and elongated strip. Specifically, the clip includes two legs formed on both sides of the strip and a blade retaining portion disposed in the middle of the strip.

With the blade support facing at least a portion of the shaving blade, two legs wrap around the side of the blade housing (aka, out-board clip fastening method), or two legs pass through the blade housing (aka, In-board clip fastening method), or by having one of the two legs wrap around one side of the blade housing and the other pass through the blade housing (aka rear-wrap clip fastening method), the clip can be secured to the blade housing. there is. However, the conventional clip has a problem in that the end of the leg is exposed on the lower surface of the blade housing.

Specifically, the conventional strip-shaped clip is generally made of a material that is easy to process such as bending or cutting. Therefore, the conventional strip-shaped clip has a problem that it is easy for a user to arbitrarily straighten the end of the clip, and is easily damaged by an external force or an external impact.

In this case, the shaving blade held by the clip may be detached from the blade housing, thereby threatening the user's safety shaving.

Accordingly, a main object of the present disclosure is to provide a razor cartridge including a clip that is firmly fixed to a blade housing and that is difficult to release from the fixed state.

According to an embodiment of the present disclosure, at least one shaving blade having a cutting edge; A blade housing for longitudinally accommodating at least one shaving blade, the blade housing comprising an upper surface facing a cutting edge and a lower surface facing the upper surface; and a clip including a clip body disposed on an upper surface and holding at least one shaving blade and two legs extending from the clip body toward a lower surface, respectively, wherein at least one of the two legs has a free end of the blade housing. It provides a razor cartridge, characterized in that the internal accommodation leg accommodated therein.

As described above, according to this embodiment, in the clip once fixed to the blade housing, the razor cartridge makes it difficult to release the fixed state, thereby providing a safe shaving effect to the user.

1 is a perspective view of a razor cartridge 10 according to an embodiment of the present disclosure.

2 is a rear perspective view of the razor cartridge 10 according to an embodiment of the present disclosure.

1 and 2 , the razor cartridge 10 may include a blade housing 120 , at least one shaving blade 110 , and a clip 130 .

The blade housing 120 may longitudinally receive at least one shaving blade 110 having a cutting edge 112 . Here, the longitudinal direction refers to a direction in which the blade housing 120 extends long. For example, in FIG. 1 , the longitudinal direction is a direction parallel to the Y axis.

The at least one shaving blade 110 may be held by the plurality of clips 130 while being accommodated on one side of the blade housing 120 .

The blade housing 120 may include a cap 122 and a guard 124 .

The cap 122 may be positioned at the rear of the shaving blade 110 , and specifically, it may be disposed on a top side 121 of the blade housing 120 facing the cutting edge 112 .

Here, the front and rear of the shaving blade 110 are defined based on the shaving direction of the razor cartridge 10 . Accordingly, in FIG. 1 , the front and rear sides of the shaving blade 110 are in the positive X-axis direction and the negative X-axis direction, respectively, with respect to the shaving blade 110 .

The guard 124 may be positioned in front of the shaving blade 110 on the upper surface 121 of the blade housing 120 .

When shaving, the guard 124 may stretch the skin in the shaving direction before cutting the hair by the shaving blade 110 .

Through this, the user's body hair can stand in a direction perpendicular to the user's skin surface, and thus, the shaving blade 110 can more easily cut the body hair.

The blade housing 120 may additionally include a rinsing hole 129 . The rinsing hole 129 may be an opening formed in the lower surface 123 of the blade housing 120 . The user may remove foreign substances accumulated between the at least one shaving blade 110 by flowing water through the rinsing hole 129 .

The clip 130 may fix the at least one shaving blade 110 to the blade housing 120 . Through this, the clip 130 may prevent the at least one shaving blade 110 from being separated from the blade housing 120 .

The clip 130 may include a clip body 132 and two legs extending from the clip body 132 toward the lower surface 123 , respectively.

The clip body 132 may be disposed on the upper surface 121 of the blade housing 120 , and may hold at least one shaving blade 110 .

At least one of the two legs may be a first inner received leg 1341 having a free end accommodated in the blade housing 120 .

The free end of the first internal accommodation leg 1341 is accommodated in the blade housing 120 , and may not be substantially exposed on the lower surface 123 of the blade housing 120 .

Therefore, after the clip 130 according to an embodiment of the present disclosure is fixed to the blade housing 120 , it is difficult to release the fixed state, and thus, it is difficult to remove the shaving blade 110 from safety considerations such as detachment. It may have the advantage of avoiding problems.

In addition, the clip 130 according to an embodiment of the present disclosure, since the free end of the first internal accommodation leg 1341 is not exposed to the outside, it may also have an aesthetic advantage.

In FIG. 2 , the free end of the first internal accommodation leg 1341 is illustrated as not exposed on the lower surface 123 , but the present disclosure is not limited thereto.

For example, even if a part of the free end of the first internal accommodating leg 1341 is exposed, most of the area of the first internal accommodating leg 1341 is located inside the blade housing 120, so that the clip 130 is It may be configured to be difficult to release from the fixed state.
