Patent Description:
The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art.

In using a wet razor, several factors can cause discomfort to the user.

For example, the friction force generated between the blade housing and the skin, the cutting force applied to the hair during cutting, irritation to a wounded skin area, etc., may cause inconvenience to the user.

To reduce such discomfort, shaving aids such as shaving foam, shaving gel, and shaving cream are used.

Shaving aids include a lubricating component and can be applied to the user's skin, which can reduce irritation applied to the skin during shaving.

A recently available razor is adapted to store a shaving aid in a razor handle and discharge the stored shaving aid from the razor cartridge thereof (hereinafter called fluid spray razors).

<CIT> (hereinafter referred to as Patent Document <NUM>), which is one of the conventional fluid spray razors, is adapted to deliver a shaving aid to a razor cartridge by using a conduit provided in the razor handle and to discharge the shaving aid from the razor cartridge. Other razors capable of delivering a shaving aid are disclosed in, for example, <CIT> and <CIT>.

However, Patent Document <NUM> has an issue of inseparability between regions of the razor cartridge, involving a region for letting in the shaving aid delivered (hereinafter, the inflow region) from the conduit (hereinafter, the fluid supply conduit) of the razor handle and another region for discharging the shaving aid (hereinafter, the discharge region) from the razor cartridge. Specifically, the inseparable inflow and discharge regions may place many restrictions on the design of a razor.

For example, the position of the fluid supply conduit and the position of the inflow region may be limited to where the discharge region can be disposed, and, conversely, the position of the discharge area may be limited by the position of the fluid supply conduit and the position of the inflow region.

In addition, the position of the fluid inflow region and the position of the discharge region may be determined under conditions that the fluid supply conduit does not interfere with the razor cartridge when pivoting the same.

Therefore, to solve the above-described deficiencies, there is an actual need for a new and original type of fluid spray razor with little design constraints.

The present disclosure provides a razor assembly as defined in claim <NUM>. Further, the invention provides a razor cartridge as defined in claim <NUM>.

The present disclosure seeks to provide a razor assembly capable of isolating portions of a razor cartridge, separating between an inlet portion for letting in a shaving aid and a discharge portion for discharging the shaving aid.

Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings. In the following description, like reference numerals would rather designate like elements, although the elements are shown in different drawings. Further, in the following description of the at least one embodiment, a detailed description of known functions and configurations incorporated herein will be omitted for the purpose of clarity and for brevity.

<FIG> is a perspective view of a razor assembly <NUM> according to at least one embodiment of the present disclosure.

As shown in <FIG>, the razor assembly <NUM> may include a razor cartridge <NUM> and a razor handle <NUM>.

The razor cartridge <NUM> includes a blade housing <NUM>, at least one or more shaving blades <NUM> and may include at least one or more clips <NUM>.

The blade housing <NUM> may accommodate the shaving blades <NUM> having cutting edges. Here, the longitudinal direction of the cutting edges corresponds to the width direction of the blade housing <NUM>. For example, in <FIG>, the longitudinal direction of the cutting edges is a direction parallel to the Y-axis.

Once accommodated on one side of the blade housing <NUM>, the shaving blades <NUM> may be retained by a plurality of clips <NUM>.

The blade housing <NUM> may include a cap <NUM>, and a guard <NUM>, and includes at least one or more discharge portions <NUM>.

The cap <NUM> may be located rearward of the shaving blades <NUM>, and specifically, may be disposed forward of the blade housing <NUM>, which the cutting edges point to.

Here, the forward and rearward directions of the shaving blade <NUM> are defined based on the shaving direction of the razor cartridge <NUM>. Accordingly, in <FIG>, the forward and rearward directions of the shaving blades <NUM> are the negative Z-axis direction and the positive Z-axis direction, respectively, with respect to the shaving blades <NUM>.

The guard <NUM>, on the front side of the blade housing <NUM>, may be located in front of the shaving blades <NUM>.

During shaving, the guard <NUM> may stretch the skin in the direction of shaving prior to cutting the hair by the shaving blades <NUM>.

This can erect the user's hair in a direction perpendicular to the user's skin surface such that the shaving blades <NUM> can cut the hair more easily.

The discharge portions <NUM> are regions on the blade housing <NUM> through which a shaving aid is ejected or discharged after being delivered through at least one or more inlet portions <NUM> and communication portions <NUM> (both of <FIG>).

Here, the shaving aid refers to various materials applied to the skin of a user to assist shaving. For example, the shaving aid may be one of, but not limited to, shaving foam, shaving gel, and shaving cream.

The shaving aid may be a fluid material, but may be other materials having fluidity. For example, the shaving aid may be a solid material in the form of a powder or a fluid material having a solid material.

During shaving, for allowing the shaving aid to be applied to the user's skin, each discharge portion <NUM> may include an opening formed in the front surface of the blade housing <NUM>.

The discharge portion <NUM> may be disposed forward of at least one shaving blade <NUM>. This enables the shaving aid to be applied to the user's skin during shaving, before cutting the hair by the shaving blade <NUM>. However, the present disclosure is not limited to this configuration.

For example, the discharge portion <NUM> may overlap the area on the blade housing <NUM> in which the shaving blade <NUM> is disposed, or may be disposed rearward of the shaving blade <NUM>.

The clips <NUM> may clip the shaving blade <NUM> to the blade housing <NUM>, thereby preventing the shaving blade <NUM> from being detached from the blade housing <NUM>.

The razor handle <NUM> may include a head portion <NUM>, a grip portion <NUM>, and a discharge operating member <NUM>.

The blade housing <NUM> may be coupled, pivotally, with respect to the head portion <NUM>, about a rotation axis (RA) parallel to the longitudinal direction of the cutting edge.

The grip portion <NUM> may extend from the head portion <NUM> and provide the user with an area for gripping the razor assembly <NUM>.

The head portion <NUM> and the grip portion <NUM> may be formed as separate members from each other, but the present disclosure is not limited thereto. For example, the head portion <NUM> and the grip portion <NUM> may be integrally formed.

The discharge operating member <NUM> may discharge a shaving aid from an aid supplying member <NUM> (<FIG>) through a discharge action.

The discharge operating member <NUM> may include a button portion and an actuator. When pressed by the user, slid by the user or otherwise moved, the button portion may activate the actuator connected to it. The actuator serves to transfer the shaving aid stored in an aid storage to the aid supplying member. The actuator may employ a mechanism capable of injecting a fluid, such as a diaphragm valve or the like.

The razor assembly <NUM> employing the diaphragm valve mechanism may include an aid storage (not shown), an aid receiving space (not shown), a first valve (not shown) disposed between the aid supplying member <NUM> and the aid receiving space, and a second valve (not shown) disposed between the aid receiving space and the aid storage.

In this case, one side of the aid receiving space may be made of an elastic tube (not shown), and the discharge operating member <NUM> may be disposed adjacent to the elastic tube. The discharge operating member <NUM> may depress the elastic tube to discharge the shaving aid from the aid supplying member.

Specifically, when pressing the discharge operating member to depress the elastic tube, the shaving aid in the aid receiving space may pressurize the first valve to open thereof. As a result, the shaving aid in the aid receiving space may be delivered to the aid supplying member <NUM> through the first valve before it is discharged. When the shaving aid in the aid receiving space is discharged to some extent, the degree of pressure on the first valve is reduced, and the first valve may be closed.

Thereafter, upon releasing the discharge operating member, the elastic tube may be restored to the original position by the elastic force, whereby the pressure inside the aid receiving space may be lowered. This will generate a flow of shaving aid to be urged from the high-pressure aid storage toward the low-pressure aid receiving space, and this flow may pressurize the second valve to open the same.

Through this arrangement, the shaving aid stored in the aid storage may be delivered to the aid receiving space. When more than a certain amount of shaving aid is delivered to the aid receiving space, the pressure difference decreases between the aid storage and the aid receiving space, so that the second valve may be closed.

The shaving aid delivered to the aid receiving space may be stored therein until the next pressing operation of the discharge operating member <NUM>.

The shaving aid discharged from the aid supplying member <NUM>, passing through the inlet portions <NUM> and the communication portions <NUM>, is emitted from the discharge portions <NUM>.

The discharge operating member <NUM> may have a configuration in which the shaving aid is discharged by a predetermined amount through a single action for discharge. However, the present disclosure is not limited to this configuration. For example, the discharge operating member <NUM> may be configured to discharge the shaving aid continuously while the discharge action is maintained.

<FIG> is a rear perspective view of the razor assembly <NUM> according to at least one embodiment.

<FIG> is an exploded perspective view of the razor assembly <NUM> according to at least one embodiment.

As shown in <FIG> and <FIG>, the razor assembly <NUM> includes a cover member <NUM> and the aid supplying member <NUM>.

The cover member <NUM> covers at least a portion of the rear surface of the blade housing <NUM>. Specifically, the cover member <NUM> may be detachably coupled to the rear surface of the blade housing <NUM>.

After detaching the cover member <NUM> from the blade housing <NUM>, the user can wash the rear surface of the blade housing <NUM>. This process helps to wash or remove foreign matters accumulated in the inlet portions <NUM>, the discharge portions <NUM>, and the communicating portions <NUM>.

By covering the communication portions <NUM> formed in the form of grooves on the rear surface of the blade housing <NUM>, the cover member <NUM> may form a completed aid transfer passage. A detailed description in this regard will be provided in connection with <FIG>.

Referring back to <FIG> and <FIG>, the cover member <NUM> may include a cover body <NUM>, at least one or more receiving valves <NUM>, and at least one or more receiving holes <NUM>.

The cover body <NUM> may be detachably coupled to the rear surface of the blade housing <NUM>.

The receiving valve <NUM> may prevent the shaving aid discharged out of the aid supplying member <NUM> at its discharge end <NUM> from backflowing and then leaking out of the razor cartridge <NUM> at an unintended position.

The receiving valve <NUM> may be disposed on the cover body <NUM> at a position corresponding to the inlet portion <NUM>, the receiving hole <NUM> may be formed laterally of the receiving plate <NUM>.

The discharge end <NUM> of the aid supplying member <NUM> inserted into the receiving hole <NUM> may be accommodated in a space between the receiving valve <NUM> and the inlet portion <NUM>.

The receiving valve <NUM> and the receiving hole <NUM> may be made of an elastic material. This enables the discharge end <NUM> and the receiving hole <NUM> taking advantage of elastic deformation to maintain the receiving valve <NUM> and the receiving hole <NUM> in firm sealing engagement, even when the razor cartridge <NUM> pivots.

In this case, to improve the sealing performance, the area of the receiving hole <NUM> may be smaller than the cross-sectional area of the discharge end <NUM>. The receiving hole <NUM> into which the discharge end <NUM> is inserted may have its area enlarged by elastic deformation, and accordingly, the outer circumferential surface of the discharge end <NUM> can be strongly pressed. However, the present disclosure is not limited to this configuation and the area of the receiving hole <NUM> may be equal to or larger than the area of the discharge end <NUM>.

The receiving valve <NUM> and the receiving hole <NUM> may be made of, but not limited to, a rubber material.

The aid supplying member <NUM> may include a supplying member body <NUM>, the discharge ends <NUM>, and at least one or more inlet ends <NUM>.

The supplying member body <NUM> may be accommodated in a receiving space <NUM> that is formed in the head portion <NUM>.

The discharge end <NUM> may extend from one side of the supplying member body <NUM>.

The discharge end <NUM> may receive the shaving aid delivered from the inlet end <NUM> communicating with the discharge end <NUM> and discharge the shaving aid to the inlet portion <NUM>.

The inlet end <NUM> may receive the shaving aid from the aid storage (not shown) of the razor handle <NUM> and may deliver the shaving aid to the discharge end <NUM>.

The head portion <NUM> may include a head frame <NUM>, at least one or more bosses <NUM>, and the receiving space <NUM>.

Inside the head frame <NUM>, the receiving space <NUM> is configured to accommodate the supplying member body <NUM>.

The bosses <NUM> may protrude laterally from the head frame <NUM> and may be inserted into boss holes <NUM> formed on the blade housing <NUM>.

The bosses <NUM> are inserted into the boss holes <NUM> to define a rotation axis RA parallel to the longitudinal direction of the cutting edge. The razor cartridge <NUM> may pivot with respect to the head portion <NUM> around the rotation axis RA.

In <FIG> and <FIG>, the aid supplying member <NUM> is illustrated as being disposed on the razor handle <NUM>, but the present disclosure is not limited to this configuration.

For example, the aid supplying member <NUM> may be disposed in any one of the razor cartridge <NUM> and a connector (not shown) that connects between the razor cartridge <NUM> and the razor handle <NUM>.

When the aid supplying member <NUM> is disposed on the connector, coupling the connector in connection with the razor cartridge <NUM> further to the razor handle <NUM> allows an aid containing member (not shown) of the razor handle <NUM> to be in communicative contact with the aid supplying member <NUM> disposed on the connector. Thus, the shaving aid in the aid containing member may be delivered to the aid supplying member <NUM> and discharged.

In addition, <FIG> and <FIG> illustrate that the head portion <NUM> and the aid supplying member <NUM> are made of separate members from each other, but the present disclosure is not limited thereto.

For example, the aid supplying member <NUM> may be integrally formed with any one of the connector (not shown), the razor cartridge <NUM>, and the razor handle <NUM>.

Still referring to <FIG> and <FIG>, the razor handle <NUM> may include a release or ejecting member <NUM>.

The ejecting member <NUM> may release the razor cartridge <NUM> from the razor handle <NUM> through an action for ejection.

Here, the action for ejection may be, but not limited to, a pushing operation or a sliding operation.

The blade housing <NUM> includes the inlet portions <NUM> and the communication portions <NUM>.

Each inlet portion <NUM> may be an area on the blade housing <NUM>, into which the shaving aid discharged from the aid supplying member <NUM> is introduced.

The inlet portion <NUM> is disposed on the back of the blade housing <NUM> for introduction of the shaving aid.

Each communication portion <NUM> is disposed between the inlet portion <NUM> and the discharge portion <NUM>, and it can communicate between the inlet portion <NUM> and the discharge portion <NUM>. In other words, the communication portion <NUM> may serve as a passage interconnecting the inlet portion <NUM> and the discharge portion <NUM>.

The communication portion <NUM> may be configured to change in depth or width as it goes from the inlet portion <NUM> to the discharge portion <NUM>.

For example, the communication portion <NUM> may be configured to decrease in depth or width as it goes from the inlet portion <NUM> to the discharge portion <NUM>. In this case, on the communication portion <NUM>, the surrounding area of the discharge portion <NUM> may have an increased flow rate relative to the surrounding region of the inlet portion <NUM>, whereby the discharge portion <NUM> may generate more powerful outflows of the shaving aid.

Conversely, the communication portion <NUM> may be configured to have its depth or width increased from the inlet portion <NUM> toward the discharge portion <NUM>. This can prevent an abrupt discharge of excessive amount of shaving aid from the discharge portions <NUM>.

However, the present disclosure is not limited to these configurations, and the communication portion <NUM> may have substantially the same depth or width along its length.

<FIG> is a rear view of the blade housing <NUM> according to at least one embodiment.

As shown in <FIG>, the inlet portion <NUM>, the discharge portion <NUM>, and the communication portion <NUM> may collectively form an aid transfer passage connected as a whole.

Here, the aid transfer passage refers to a flow path through which the shaving aid delivered from the razor handle <NUM> can flow inside the razor cartridge <NUM>.

The discharge portions <NUM> may be disposed spaced apart from the inlet portions <NUM> along the longitudinal direction of the cutting edge. Specifically, the discharge portions <NUM>, on the blade housing <NUM>, may be disposed laterally inside of the inlet portions <NUM>. However, the present disclosure is not limited to this configuration.

For example, the discharge portions <NUM>, on the blade housing <NUM>, may be disposed laterally outside of the inlet portions <NUM>.

The discharge portion <NUM> may be disposed spaced apart from the inlet portion <NUM> in the transverse direction, which is parallel to the shaving direction and is perpendicular to the longitudinal direction of the cutting edge. Specifically, the discharge portions <NUM>, on the blade housing <NUM>, may be disposed in the front of the inlet portions <NUM> in the transverse direction.

However, the present disclosure is not limited to this configuration. For example, the discharge portions <NUM> may be disposed on the blade housing <NUM> in the rear of the inlet portions <NUM> in the transverse direction.

Here, the transverse direction corresponds to the height direction of the blade housing <NUM>. For example, in <FIG>, the transverse direction is a direction parallel to the Z-axis. In addition, in <FIG>, the front and rear in the transverse direction are the negative Z-axis direction and the positive Z-axis direction, respectively.

Each discharge portion <NUM> is spaced apart from the inlet portion <NUM> both transversely and longitudinally. In this case, the discharge portion <NUM> may be spaced diagonally from the inlet portion <NUM>. However, the present disclosure is not limited to this configuration.

For example, the discharge portion <NUM> may be spaced apart only in the transverse direction or only in the longitudinal direction from the inlet portion <NUM>.

Multiples of the inlet portion <NUM> and multiples of the discharge portion <NUM> may be provided on the blade housing <NUM>. However, the present disclosure is not limited thereto, and a single inlet portion <NUM> or a single discharge portion <NUM> may be provided on the blade housing <NUM>.

With the razor assembly <NUM> according to at least one embodiment of the present disclosure, one technical advantage of connecting the inlet portion <NUM> and the discharge portion <NUM> through the communication portion <NUM> includes providing design freedom for repositioning any number of the inlet portions <NUM> and the discharge portions <NUM> as appropriate.

Thus, the razor assembly <NUM> according to at least one embodiment of the present disclosure has fewer design constraints and, at the same time, has an effect of spraying or applying a shaving aid more effectively.

Meanwhile, the communication portion <NUM> has a recessed shape on the rear surface of the blade housing <NUM>. In other words, the communication portion <NUM> has a shape of a groove formed along the aid transfer passage. In this case, the communication portion <NUM> has one side opened on the blade housing <NUM>.

The open side of the communication portion <NUM> is closed by the cover member <NUM> disposed on the rear surface of the blade housing <NUM>. This completely defines the aid transfer passage between the blade housing <NUM> and the cover member <NUM>. In this case, the aid transfer passage may have all areas thereof closed except the area where the shaving aid is introduced and the area where the latter is discharged.

With the razor assembly <NUM> according to the present invention, one technical advantage includes providing the communication portion <NUM> in the form of a groove and closing an open side of the groove with the cover member <NUM> to form the aid transfer passage.

In general, the process of forming a groove on the surface of the blade housing <NUM> is easier compared to the process of forming a through path inside the blade housing <NUM>. Therefore, the razor assembly <NUM> according to at least one embodiment of the present disclosure may use a simpler process for forming an aid transfer passage easily.

The discharge portion <NUM> may have a shape penetrating the blade housing <NUM> in the thickness direction. In this case, one opening of the discharge portion <NUM>, which is formed on the rear surface of the blade housing <NUM>, may be closed by the cover member <NUM>.

Here, the thickness direction corresponds to a direction in which the thickness of the blade housing <NUM> is formed. For example, in <FIG>, the thickness direction is a direction parallel to the X-axis.

The shaving aid delivered to the discharge portions <NUM> may be prevented from being discharged from the rear surface of the blade housing <NUM> by the cover member <NUM>. This guides the shaving aid to be collected in the discharge portions <NUM>.

When a predetermined amount of shaving aid is collected in the discharge portions <NUM>, the shaving aid may be discharged through the other opening of the discharge portions <NUM>, which is formed on the front surface of the blade housing <NUM>.

Accordingly, the razor assembly <NUM> according to at least one embodiment of the present disclosure has a manufacturing advantage that can form the discharge portions <NUM> through a simple process of penetrating the blade housing <NUM>.

<FIG> is a side cross-sectional view of the razor assembly <NUM> according to at least one embodiment.

<FIG> is a side cross-sectional view of the razor assembly <NUM> of <FIG> having been pivoted.

As shown in <FIG>, the blade housing <NUM> may pivot with respect to the head portion <NUM> around rotation axis RA parallel to the longitudinal direction. Rotation axis RA may be defined by inserting the bosses <NUM> of the head portion <NUM> into the boss holes <NUM> of the blade housing <NUM>.

The discharge ends <NUM> inserted into the receiving holes <NUM> may not interfere with the inlet portions <NUM> when the blade housing <NUM> rotates around the rotation axis RA. Accordingly, the blade housing <NUM> can pivot freely with respect to the head portion <NUM>.

Rotation axis RA may penetrate the discharge ends <NUM> when the blade housing <NUM> rotates around the rotation axis RA. This can minimize the space occupied by the discharge end <NUM> when the blade housing <NUM> is rotated, thereby minimizing the interference of the discharge ends <NUM> with the inlet portions <NUM>.

Alternatively, rotation axis RA may be configured to be positioned adjacent to the discharge ends <NUM> or to penetrate the inlet portions <NUM> without passing through the discharge ends <NUM>.

The second to sixth embodiments of the present disclosure shown in <FIG> to be described below are different from the at least one embodiment as illustrated in <FIG> in terms of the position and the number of the inlet portions and the discharge portions. The following will concentrate on the distinctive features according to the respective embodiments of the present disclosure, and repeated descriptions of the same components as the at least one embodiment will be omitted.

<FIG> is a rear view of a blade housing <NUM> according to a second embodiment of the present disclosure.

<FIG> shows discharge portions <NUM> which may overlap an area of the blade housing <NUM> in which at least one shaving blade is disposed. In this case, the shaving aid discharged from the discharge portions <NUM> may be discharged from the back of the shaving blade to the front thereof.

The razor assembly according to the second embodiment of the present disclosure is configured to discharge the shaving aid to an area where the shaving blade is disposed so that the hair may be cut by the shaving blade while the shaving aid is applied to the user's skin. This results in minimized damage to the skin due to shaving.

<FIG> is a rear view of a blade housing <NUM> according to a third embodiment of the present disclosure.

<FIG> shows communication portions <NUM> each including a converging portion <NUM>, a divergence point <NUM>, and a plurality of diverging portions <NUM>.

The converging portions <NUM> may communicate at least one of inlet portions <NUM> formed on the blade housing <NUM> to the divergence point <NUM>, and the plurality of diverging portions <NUM> may communicate with a plurality of discharge portions <NUM> formed on the blade housing <NUM>, respectively.

The converging portions <NUM> may receive the shaving aid from at least one inlet portion <NUM> and deliver the shaving aid to the divergence point <NUM>.

The shaving aid delivered to the divergence point <NUM> may temporarily stay therein and the shaving aid may be further delivered after passing through the diverging portions <NUM> to the respective discharge portions <NUM>.

The razor assembly according to the third embodiment of the present disclosure is configured to converge the shaving aid from one or more inlet portions <NUM> and deliver the converged shaving aid to the plurality of discharge portions <NUM>, thereby providing an aid transfer passage with a more simplified shape.

In addition, the razor assembly according to the third embodiment of the present disclosure has an effect of maintaining the function of discharging the shaving aid even if a part of the aid delivery passage is blocked by foreign material or the like.

For example, when a plurality of the inlet portions <NUM> and the converging portions <NUM> are provided, even if one of the plurality of converging portions <NUM> is blocked due to the accumulation of foreign materials or the like, the other converging portion <NUM> may permit the shaving aid to be passed on to the divergence point <NUM>. Once delivered to the divergence point <NUM>, the shaving aid may be discharged from all of the discharge portions <NUM>.

<FIG> is a rear view of a blade housing <NUM> according to a fourth embodiment of the present disclosure.

As shown in <FIG>, the blade housing <NUM> may include a single inlet portion <NUM> and a plurality of discharge portions <NUM>.

The shaving aid introduced into the single inlet portion <NUM> may be delivered to the respective discharge portions <NUM> through a plurality of communicating portions <NUM> diverging from the inlet portion <NUM>.

The razor assembly according to the fourth embodiment of the present disclosure uses the single inlet portion <NUM> and a plurality of discharge portions <NUM> in configuring the aid transfer passage to further simplify the shape of the aid delivery channel.

With the razor assembly according to the fourth embodiment of the present disclosure, the discharge portions <NUM> may be arranged with more freedom of design choice, enabling multiple discharge portions <NUM> to be distributed over the blade housing <NUM> for discharging the shaving aid over a wider area.

<FIG> is a rear view of a blade housing <NUM> according to a fifth embodiment of the present disclosure.

As shown in <FIG>, the blade housing <NUM> may include a plurality of inlet portions <NUM> and a single discharge portion <NUM>.

The shaving aid introduced into the plurality of inlet portions <NUM> may converge to one discharge portion <NUM> through a plurality of communicating portions <NUM>.

The razor assembly according to the fifth embodiment of the present disclosure uses a plurality of inlet portions <NUM> and one discharge portion <NUM> to make up the aid transfer passage, and thereby further simplifying the shape of the aid transfer passage.

In addition, the razor assembly according to the fifth embodiment of the present disclosure is configured to deliver the shaving aid from a plurality of inlet portions <NUM> to one discharge portion <NUM>, thereby discharging relatively large amounts of shaving aid intensively to a specific position of the razor cartridge.

In addition, the razor assembly according to the fifth embodiment of the present disclosure may have a shape in which the discharge portion <NUM> is elongated in the longitudiunal direction. In this case, the shaving aid may be evenly discharged from the discharge portion <NUM> over a wider area.

<FIG> is a rear view of a blade housing <NUM> according to a sixth embodiment of the present disclosure.

As shown in <FIG>, the blade housing <NUM> may include a plurality of inlet portions <NUM> and a single discharge portion <NUM>. In addition, the single discharge portion <NUM> may include a plurality of discharge openings <NUM>.

In <FIG>, the blade housing <NUM> is illustrated as having the single discharge portion <NUM>, but the present disclosure is not limited thereto.

For example, the blade housing <NUM> may be provided with multiples of the discharge portion <NUM>, and each of the discharge portions <NUM> may include a plurality of discharge openings <NUM>.

The plurality of discharge openings <NUM> may be disposed on the discharge portion <NUM> to be spaced apart from each other along the longitudinal direction. However, the present disclosure is not limited to this configuration. For example, the plurality of discharge openings <NUM> may be disposed on the discharge portion <NUM>, spaced apart in the transverse direction, or sporadically disposed over a specific area.

The shaving aid delivered from the inlet portions <NUM> may be delivered to the single discharge portion <NUM> after passing through communication portions <NUM> which are formed on the blade housing <NUM>.

The shaving aid delivered to the single discharge portion <NUM> may be discharged from the razor cartridge through the plurality of discharge openings <NUM>, simultaneously and over a large area.

On the other hand, when compared to the case where the discharge portion <NUM> has a single opening, the amount of shaving aid discharged from each of the discharge openings <NUM> may be less.

Accordingly, the razor assembly according to the sixth embodiment of the present disclosure is configured to provide the single discharge portion <NUM> with a plurality of discharge openings <NUM> so that the same amount of shaving aid is applied thinly over a larger area.

The second to sixth embodiments of the present disclosure shown in <FIG> are merely some of the various embodiments of the present disclosure. Accordingly, the razor assembly according to the present disclosure may have other various embodiments than the above-described embodiments.

As described above, the razor assembly according to some embodiments of the present disclosure provides design freedom for allowing the inlet portion for letting in the shaving aid and the discharge portion for discharging the shaving aid to be repositioned to effect more efficient shaving routine.
