  15. A cover portion having a shape extended by a predetermined length to cover at least a portion of the shaving plane of a razor cartridge so as to come into contact with the surface of the skin when shaving, and to cover some of the plurality of blades of the razor cartridge while exposing other portions of the plurality of blades; and It includes coupling portions provided on both sides of the above-mentioned cover portion and coupled to the blade housing of the above-mentioned shaver cartridge, and It is configured to be detachably coupled to the above-mentioned shaver cartridge, and The above-detachable member is formed in a structure that forms a step and is connected to both ends of the cover portion so as to be detachably coupled to the blade housing protruding higher than the cutting edge of the blade.
  16. In paragraph 15, The upper surface of the above-mentioned cover portion forms an area in which at least a portion comes into contact with the user's skin, and A detachable member having a shape that is bent so as to be joined by wrapping a portion of the blade housing on both sides of the cover portion, at least a portion of the above-mentioned connecting portion.

Description

Razor Cartridge and Attachable Member The present invention relates to a razor cartridge and a detachable member installed in the razor cartridge, and more specifically, to a razor cartridge and a detachable member capable of improving shaving stability. A razor assembly known as a wet razor is composed of a razor cartridge and a razor handle. The razor cartridge includes multiple blades, thereby forming a shaving plane. The razor cartridge is detachably coupled to the razor handle, and the user can replace the razor cartridge as needed. Recently, some products offer razor cartridges equipped with non-cutting elements. These non-cutting elements are positioned between the blades or between the cap or guard and the blades. Razor cartridges equipped with these elements have the advantage of temporarily relieving pressure applied to the skin surface by the blades, thereby improving user comfort and shaving stability, and providing a low-irritation shave. On the other hand, because cutting performance is relatively inferior compared to razor cartridges without non-cutting elements, they are disadvantageous for achieving a clean shave that cuts down to the underside of body hair. Therefore, there is a need for the development of products capable of responding to various shaving environments, such as shaving position and hair condition.

FIG. 2 is a front view illustrating a razor cartridge with a detachable member attached in FIG. 1. Figure 3 is a drawing illustrating the detachable member of Figure 1. FIG. 4 is a perspective view showing the side of the blade housing of FIG. 2. FIG. 5 is a perspective view illustrating a blade housing according to another embodiment of the present invention. FIG. 6 is a side view illustrating a side of a blade housing according to another embodiment of the present invention. FIG. 7 is a cross-sectional view illustrating various examples of the cross-sectional structure of the detachable member of FIG. 1.

FIG. 9 is a perspective view illustrating a detachable member according to another embodiment of the present invention. FIG. 10 is a perspective view illustrating the shape of a detachable member according to another embodiment of the present invention. Hereinafter, a razor assembly, a razor cartridge, and a detachable member according to an embodiment of the present invention will be described in detail with reference to the drawings. In the following description, the positional relationships of each component are described in principle based on the drawings, and are defined separately if necessary. The drawings may simplify the structure of the invention or, if necessary, exaggerate it for the convenience of explanation. However, the present invention is not limited thereto, and it is understood that various components may be added, modified, or omitted in addition to the above. Furthermore, in describing the configuration of the embodiments below, the statement that a higher-level component ‘includes’ or ‘possesses’ other lower-level components should be understood on the premise that it may include lower-level components other than those described. FIG. 1 is an exploded perspective view illustrating a razor assembly according to one embodiment of the present invention. As shown in FIG. 1, the razor assembly (1) of the present embodiment includes a razor cartridge (10) equipped with a plurality of blades (200) and a handle (20) coupled to the razor cartridge (10). The razor cartridge (10) may be rotatably connected to the handle (20), but may also be connected so as to be fixed in position relative to each other. The razor handle (20) may include a grip portion (21) forming a body and a head portion (22) to which the razor cartridge (10) is coupled. The grip portion (21) is a part that is held by the user and is shaped to extend a predetermined length from the head portion (22) to the other side, forming the body of the razor handle (20). The head portion (22) is provided on one side of the grip portion (21) and is configured to selectively connect a razor cartridge (10). The head portion (22) may optionally include an operating portion (not shown) for operating to detach the razor cartridge. The razor assembly (1) may additionally include a connector (not shown) positioned between the razor cartridge (10) and the razor handle (20). The connector may connect the razor cartridge (10) and the razor handle so that the razor cartridge (10) can rotate relative to the razor handle (20). The connector may be rotatably coupled to the razor cartridge (10) or coupled so that the mutual positions are fixed to the razor cartridge (10). Meanwhile, the razor cartridge (10) is configured to perform a shaving action by
