Description

Skin Contact Member for Razor Cartridge The present disclosure relates to a skin contact member for a razor cartridge. The content described in this section merely provides background information regarding the present disclosure and does not constitute prior art. When using a wet shaver, the frictional force generated between the blade housing and the user's skin, the cutting force applied to the hair to cut the hair, and irritation to areas of skin with cuts can cause discomfort to the user. To alleviate this inconvenience, shaving aids such as shaving foam, shaving gel, and shaving cream may be used. Shaving aids contain lubricating ingredients and are applied to the user's skin before or after shaving. This can reduce irritation to the user's skin during shaving. When shaving with a wet razor and shaving aids such as shaving foam, there is a problem where the shaving aid moves away from the application site and disappears due to water or repeated strokes, and when the razor cartridge is configured to hold and retain the shaving aid, there is a problem where the shaving aid is not discharged, resulting in excessive retention or difficulty in cleaning. Accordingly, a structure is required that allows the shaving aid to be properly retained without being excessive or insufficient during the user's shaving, while also enabling the smooth discharge of the shaving aid and cut hair during washing, etc. FIG. 1a is a perspective view of a razor cartridge according to one embodiment of the present disclosure. FIG. 1b is a perspective view of a razor cartridge according to another embodiment of the present disclosure. FIG. 2 is an exploded perspective view of a razor cartridge according to one embodiment of the present disclosure. FIG. 3 is a perspective view of a skin contact member according to one embodiment of the present disclosure. FIG. 4 is a front view and a partial plan view of a skin contact member according to one embodiment of the present disclosure. Figure 5 is a cross-sectional view taken along V-V' of Figure 4. FIG. 6 is a cross-sectional view taken along VI-VI' of FIG. 1, showing the combined structure of a skin contact member and a housing of a razor cartridge according to the present disclosure. FIG. 7 is a perspective view of a skin contact member according to another embodiment of the present disclosure. FIG. 8 is a front view and a partial plan view of a skin contact member according to another embodiment of the present disclosure. Figure 9 is a cross-sectional view taken along IX-IX' of Figure 8. FIGS. 10 and 11 are drawings showing examples of grooves formed in a skin contact member according to the present disclosure. Some embodiments of the present disclosure are described in detail below with reference to exemplary drawings. It should be noted that in assigning reference numerals to the components of each drawing, the same components are given the same reference numeral whenever possible, even if they are shown in different drawings. Furthermore, in describing the present disclosure, if it is determined that a detailed description of related known components or functions could obscure the essence of the present disclosure, such detailed description is omitted. In describing the components of the present invention, terms such as first, second, A, B, (a), (b), etc. may be used. These terms are used merely to distinguish the components from other components, and the essence, order, or sequence of the components is not limited by the terms. Where it is stated that one component is 'connected', 'combined', or 'joined' to another component, it should be understood that while the component may be directly connected or joined to the other component, another component may also be 'connected', 'combined', or 'joined' between each component. Throughout the specification, when a part is described as 'including' or 'equipped' with a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. Terms such as '…part', 'module' as described in the specification refer to a unit that processes at least one function or operation, and this may be implemented in hardware, software, or a combination of hardware and software.
