    FIELD OF THE INVENTION
    [0001] The present invention relates to a shaver or epilator with manually dispensable liquid dispensing. In particular, the invention relates to a razor or epilator cartridge for a razor or epilator with manually actuated liquid dispensing. BACKGROUND OF THE INVENTION
    [0002] The present invention relates to the wet shaving or epilation field, which is the process in which a razor or epilator with one or more sharp blades moves along the skin to cut hair. When a consumer dedicates himself to the experience of shaving or wet hair removal, it is common to apply a preparation to the skin, such as shaving or shaving soap, shaving or shaving cream, shaving or shaving gel, hair conditioning foam. skin, etc., by means of a brush or a manual application prior to the movement of the razor or shaving along the surface of the skin. Most consumers find this type of preparation somewhat inconvenient due to the need for multiple products for shaving or hair removal, for example, a wet shaver or epilator and a skin preparation product, as well as the undesirable need for multiple steps of application during the shaving or wet hair removal process. This multi-step process also results in an extensive shaving or waxing experience in general, which most consumers do not appreciate given the typical morning hygiene routines. However, it may sometimes be desirable to apply fluids of other types to the skin before, during or after shaving or waxing. It has been found that, especially in the case of male individuals, who shave or shave facial hair, it is important to provide a preparation for shaving or epilation of some kind before shaving or epilation, in order to properly hydrate hair thicker facials to allow for a closer and easier shave or epilation.
    [0003] In the past, there have been numerous shaving or wet hair removal product configurations that include a system for transporting a shaving or hair removal preparation during shaving or hair removal, for example, a lubricating fluid, from a reservoir built into the shaver or shave frame in the form of a shaver or shave handle with a cavity inside it, or even an aerosol can that acts as a shaver or shave handle, to a nearby dispensing location the head of the shaver or shave. Numerous newer wet shavers or shavers have cartridges that are mobile-mounted, in particular pivotable, in relation to the cable structures on which they are permanently mounted, in the case of disposable safety shavers or epilators intended to be disposed of. when the blade or blades lose their edge, or to allow, in a detachable way, the replacement of the blade unit in a reusable cable structure. An exemplary razor or shaver of this type is disclosed in US Patent No. 6,789,321 or US Patent No. 7,127,817. Many of these types of razors or shavers that are able to carry a liquid to the skin's surface are unfortunately affected by numerous problems. For example, the internal mechanisms of shavers or shavers tend to be prohibitively expensive from a large-scale manufacturing point of view. In addition, there are safety and performance issues that are constantly experienced due to microbial growth in the reservoir caused by continuous exposure of a portion of the remaining liquid to the air. This exposure of the liquid to air can often result in obstruction of the internal mechanisms of the razor or shave by the liquid, resulting in a shaving or shaving product with poor performance.
    [0004] Despite known shortcomings in relation to shaving or shaving with liquid dispensing, there is a need for a shaver or shaving device that is capable of dispensing a liquid during shaving or epilation that is inexpensive and reliable . In particular, there is a need for a razor or epilator for shaving or wet epilation with liquid dispensing that can dispense a composition during shaving or epilation when the skin needs it most and that solves the problems of obstruction and microbial growth previously mentioned. SUMMARY OF THE INVENTION
    [0005] In one aspect, the invention features a razor or epilator for shaving or wet epilation that dispenses a fluid during shaving or epilation. The razor or shave for wet shaving or epilation includes a replaceable razor or shaving cartridge comprising a housing having an upper portion, a lower portion, a front portion and a rear portion. At least one blade is positioned between the upper portion and the lower portion and the openings are located between the upper portion and the lower portion that extends from the rear surface to the front surface of the housing. A cartridge connection structure is attached to the rear surface of the housing and includes a fluid dispensing element attached to the cartridge connection structure. The fluid dispensing element preferably has at least one, two dispensing element flow paths with two dispensing element supply end holes and two dispensing element discharge end holes. The two discharge end holes of the dispensing element are in fluid communication with the openings in the housing. The dispensing element flow paths converge from the dispensing element supply end holes to the dispensing element discharge end holes, so that the cross sections of the dispensing element flow paths decrease the from the dispensing element supply end holes to the two dispensing element discharge end holes.
    [0006] The shaving or shaving apparatus for shaving or wet hair removal comprises a handle having a length extending from a proximal end to a distal end. The cable includes a cavity for housing a fluid reservoir disposed within the cable near the distal end, a connector port disposed at the proximal end and a manually operated pump located along the length of the cable between the reservoir and the connector port.
    [0007] The connector port comprises a connector port supply end having a hole and a connector port discharge end having a hole with a connector port flow path between them. The connector port flow path includes a converging cross section, so that the cross section of the connector port flow path decreases from the supply end hole to the discharge end hole. Alternatively, the connector port comprises a Y-shaped flow path, where the supply end of the connector port has a hole and the discharge end of the connector port has two holes with the Y-shaped flow path. connector port to each other. For the present embodiment, the connector port flow path comprises a supply end flow path which leads to two discharge end flow paths. The supply end flow path and the two discharge end flow paths include converging cross sections, so that the cross sections of each flow path decrease in the flow direction.
    [0008] The fluid dispensing element is in fluid communication with the reservoir and the pump through the connector port when the cartridge connection structure engages the proximal end of the cable.
    [0009] A hollow space or cavity can be interposed between the discharge end hole of the connector port and the supply end holes of the dispensing element for the connector port configuration that has the unique converging flow path design. . The hollow space or cavity can be formed as part of the cartridge connection structure. For connector port configuration that includes the Y-shaped flow path, the two discharge ends of the connector port flow path can interface directly with the holes in the fluid dispensing element supply end.
    [0010] In another embodiment, the razor or shaving cartridge includes a housing, a lid and at least one blade mounted on the housing. The blade has a blade edge on the front of the cover. A bulkhead is located in front of the blade. The bulkhead defines an elongated recess or groove having a total width that extends parallel to the blade which is 70% to 100% of the total width of the bulkhead. The elongated recess is in fluid communication with the discharge end hole of the fluid dispensing element through the openings in the cartridge housing and can be filled with the fluid pumped from the reservoir.
    [0011] In order to accommodate the flow of fluid throughout the articulation range of the cartridge, the holes in the discharge end of the fluid dispensing element are widened. The outer surfaces of the fluid dispensing element adjacent to the discharge end holes have a concave curvature towards the hole, while the inner surfaces of the holes form a beveled edge. The enlarged holes interface with the openings in the housing. An elongated recess or channel in the bulkhead, which is in fluid communication with the openings, can provide an even distribution of the fluid over the length of the blades. The micropents in the bulkhead, between the channel and the blades, can distribute the fluid evenly across the blade gap.
    [0012] A pump is arranged between the reservoir and the connector port. The pump may comprise a resilient tube interposed between the first and the second connectors. The first and second connectors include first and second valves, respectively. The first connector is attached to the reservoir and the second connector is attached to the hole in the connector port. The resilient tube has a neutral position with both valves closed and a second position with an open valve and a closed valve.
    [0013] The fluid is stored in a reservoir disposed in a cavity at the distal end of the cable opposite the connector port. The reservoir is replaceable and comprises an external container that surrounds a retractable internal container and includes a fluid outlet adapted to allow the fluid to exit both the retractable reservoir and the container. A hole arranged in the outer container is adapted to allow air to flow in and out of the container. The fluid outlet is in fluid communication with the pump that draws the fluid out of the retractable reservoir. The fluid outlet may include a frangible seal that is penetrated by a perforator at the end of the first connector when connecting the reservoir to the pump. The reservoir can be arranged at the distal end of the cable and can comprise an exposed container or vial. Alternatively, the reservoir can be covered by an end cap.
    [0014] Other features and advantages of the invention will be evident from the description and drawings, as well as from the claims. BRIEF DESCRIPTION OF THE DRAWINGS

    [0028] Figures 1 to 3 show a razor or epilator for shaving or wet epilation with liquid dispensing (100) to dispense a fluid during shaving or epilation which includes a handle (200) and an appliance cartridge shaving or shaving (300). The cable (200) has a length (L) that extends from a proximal end (204) to a distal end (206). The cable also includes a cavity (208) for housing a reservoir (230) disposed inside the cable (200) and a manually operated pump (240) located along the length (L) of the cable (200). The pump assembly (240) is adapted to move the fluid from the reservoir (230) to a connector port (400) at the proximal end (204) of the cable (200).
    [0029] Referring to Figure 1 to 3, the razor or shaving cartridge (300) includes a housing (302) having an upper portion (304), a lower portion (306), a front surface (308) and a rear surface (310). At least one blade (314) is positioned between the upper portion (304) and the lower portion (306). The razor or shaving cartridge (300) may also include multiple blades. For example, US Patent No. 7,168,173 describes a Fusion® razor or shaver that is commercially available from The Gillette Company, which includes a razor or shaving cartridge with multiple blades. Additionally, an opening (316) is located between the upper portion (304) and the lower portion (306) so that the opening (316) extends from the rear surface (310) to the front surface (308). In one embodiment, the housing (302) may also contain clips that are useful for retaining and maintaining the stability of the blades before, during and after using the razor or shaving device.
    [0030] The cartridge (300) is fixed to the rear surface (310) of the housing (302) by a cartridge connection structure (312). The cartridge connection structure (312) includes two arms (336) that extend to provide pivoting support to the housing (302). The cartridge is capable of pivoting around a predetermined axis located below the surface of the bulkhead (330). (The openings 316a and 316b are preferably located at or near the pivot axis widely described below).
    [0031] The razor or shaving cartridge (300) may also include a shield (330) and / or a lubricating strip (332) on the front surface (308) located between the upper portion (304) and the lower portion ( 306) of the housing (302). The shield (330) is useful for stretching the skin surface immediately before contact with the blade or with a first blade (when more than one blade is present). This shield (330) can typically comprise an elastomeric element to allow a contact to be comfortable for a user. US patent 7,168,173 discloses a suitable razor or shaving cartridge and elastomeric material without the openings. The elastomeric material can be selected as desired. Typically, the elastomeric material used is a block copolymer (or other suitable materials), for example, having a durometer between 28 and 60 Shore A.
    [0032] The razor or shaving cartridge may also include a micropent (333) shown in Figure 5 and disclosed in U.S. Patent No. 8,209,867. The micropent (333) includes a plurality of projections that define a plurality of open slits that extend generally perpendicular to the edge of the blade. The open slits have a minimum dimension to allow free passage of hair through the edge of the blade and a maximum dimension that prevents the skin from being inserted between the slits and consequent irritation. The micropents are arranged between the blade edge and the openings (316a and 316b) in the housing and serve as flow channels that provide an even distribution of fluid in front of the blade edge.
    [0033] The lubricating strip, on the other hand, provides an additional treatment to the skin after contact between the fluid and the skin has occurred. The lubricating strip can contain the same ingredients for the skin or additional ingredients to those that are present in the fluid. Suitable lubricating strips are disclosed in US patents Nos: 7,069,658, 6,944,952, 6,594,904, 6,182,365, D424,745, 6,185,822, 6,298,558 and 5,113,585. The lubricating strip can be located anywhere on the cartridge and contains electrolyte that is released to the skin, which further facilitates the spreading of the thickened / suspended polymeric ingredients. The electrolyte can be charged polymers, salts, surfactants or mixtures contained therein.
    [0034] The cartridge connection structure (312) can be releasably attached to the cable (200), as disclosed in US patents Nos. D533,684, 5,918,369 and 7,168,173. This disengagement of these two components allows the replacement of shaving or shaving cartridges, since the continuous use of such cartridges causes loss of the blade edge. Thus, such cartridges are replaceable and disposable according to the user's wishes.
    [0035] The razor or shaving cartridge 300 comprises a pivot axis around which the cartridge housing 302 is mounted to the cartridge connection structure (312). In one embodiment, the one or more openings 316a and 316b in the front surface 308 of the cartridge are positioned on or near the pivot axis. One or more openings allow the fluid to be discharged directly into the skin on or near the predetermined pivot axis. Non-limiting examples of devices having similar arrangement of fluid discharge positions are available in U.S. Patent No. 6,789,321. In one embodiment, the device comprises a plurality of holes, wherein one or more of said plurality of holes are positioned on or near the pivot axis. The one or more holes can generally form a line that extends over a portion of said pivot axis. The device may also have only one orifice which is generally elongated in shape and which extends laterally towards the side ends of the razor cartridge, which extends over a portion of the pivot shaft. The provision of one or more orifices positioned over a portion of any fluid dispensed on the pivot axis would have a greater chance of forming a thin yet wide ribbon of the fluid. Non-limiting examples of suitable orifices are provided in the present invention and are also available from U.S. Published Patent Application No. 20110219621 A1. Fluid Dispensing Element
    [0036] The razor or shaving cartridge shown in Figures 4a to 4c comprises a fluid dispensing element (318) attached to the cartridge connection structure (312). The fluid dispensing element (318) includes two dispensing element flow paths 320a and 320b with two dispensing element supply end holes 322a and 322b and two dispensing element discharge end holes 326a and 326b. The two supply end holes of the fluid dispensing element 322a and 322b are in fluid communication with the connector port discharge end holes (s) when the cartridge connection frame engages the proximal end of the cable and the two discharge end holes of the dispensing element (326a and 326b) are in fluid communication with the openings 316a and 316b in housing 302. The flow paths of the fluid dispensing element (320a and 320b) converge at from the dispensing element supply end holes (322a and 322b) to the dispensing element discharge end holes 326a and 326b, so that the cross sections of the dispensing element flow paths (322a and 322b) decrease from the two holes of the dispensing element supply end (322a and 322b) to the two holes of the dispensing element discharge end (326a and 326b). The cross sections of the dispensing element flow paths (320a and 320b) can decrease continuously from the supply end holes (322a and 322b) to the discharge end holes (326a and 326b). The cross sections can decrease in the horizontal H direction, in the vertical V direction or in both. For example, the cross sections of the flow paths (320a and 320b) for the dispensing element 318 in the connection structure (312) shown in Figures 4b and 4c, decrease in both the horizontal H and vertical V direction. from the fluid dispensing element supply end holes 322a and 322b with the connector port discharge end hole (s), the fluid dispensing element (318) is in fluid communication with the pump ( 240) and the activation of the pump (240) displaces the fluid from the reservoir (230) in the cavity (208) through the openings (316) up to or adjacent to the front surface (308) of the housing (302).
    [0037] If there is an obstruction or a problem occurs in the flow paths (320) and (320b) and / or in the razor or shaving cartridge (300), for example, the blades lose their thread, a user can simply replace the cartridge (300) and the attached fluid dispensing element (318). The fluid dispensing element (318) can be integrally formed with the cartridge connection structure (312). For example, the fluid dispensing element (318) can be shaped and / or formed as a single assembly with the cartridge connection structure (312).
    [0038] The dispensing end (328) of the dispensing element (318) extends to or adjacent to the openings 316a and 316b in the housing (302). In the partial view of the cartridge housing 302 and the dispensing end 328 of the fluid dispensing element 318, shown in Figure 5, the dispensing end (328) engages in an engaging manner with the razor or epilating cartridge (300) at the opening (316b). To prevent fluid leakage while the shaver or shaver (100) is not in use, any or all of the holes (for example, 322a, 322b, 326a and 326b) may include a check valve, for example, a valve screwdriver, a duckbill check valve or other suitable valves.
    [0039] As shown in Figure 5, the fluid dispensing element (318) has discharge end holes (326a, 326b) at the dispensing end (328) and the razor or shaving cartridge (300) includes openings (316a, 316b). The holes in the discharge end (326a and 326b) in the dispensing end (328) of the fluid dispensing element (318) can be chamfered. As shown, the edges of the discharge end holes (326a and 326b) are arranged at an angle to the holes to accommodate a whole hinge band of the razor or epilator cartridge 300. In this embodiment, the dispensing end ( 328) protrudes outward and extends to the plurality of openings (316a, 316b) up to or adjacent to the front surface (308). By engaging the supply end holes (322a and 322b) of the fluid dispensing element (318) with the connector port flow path (4425), the fluid dispensing element (318) enters fluid communication with the pump (240). The actuation of the pump (240) moves the fluid (210) from the reservoir (230) through the openings (316a, 316b) to or adjacent to the front surface (308) of the housing (302). Connector Port
    [0040] The connector port 400 shown in Figures 6a and 6b comprises a connector port supply end 420 having a hole 410 and a connector port discharge end (450) having a hole (440) with a travel path. connector port flow 425 to each other. The flow path of the connector port 425 includes a converging cross section, so that the cross section of the flow path of the connector port contracts from the supply end hole 410 to the discharge end hole 440. A Cross section decrease refers to the reduction of the area as the flow path advances from the supply end hole 410 to the discharge end hole 440 along the flow path. For the connector port shown in Figures 6a and 6b, the cross sections can decrease in the horizontal direction H, in the vertical direction V or both. For example, the cross section of the flow path (425) to the connector port (400) shown in Figures 6a and 6b, decreases in the vertical direction V.
    [0041] To provide a visual indication of the fluid flowing through the razor or shaving set, the connector port 400 may include a transparent or translucent window that provides a visual indication that the fluid is flowing through the connector port 400. The transparent or translucent window can be arranged in any portion of the connector port that is exposed. As shown in Figure 2 and Figure 6b, the lower portion 460 of the connector port 400 may comprise a transparent or translucent window that is exposed on the lower portion of the razor or shave for shaving or wet hair removal with liquid dispensing (100 ).
    [0042] As shown in Figure 7, connector port 500 can have two connector port discharge end holes 540a and 540b that connect to a single connector port supply end hole 510 with a flow path Y-shaped to each other. The Y-shaped flow path comprises a supply end flow path 520 which leads to two discharge end flow paths 530a and 530b. The flow path of the supply end 520 and the two flow paths of the discharge end 530a and 530b include converging cross sections, so that the cross sections of each of the flow paths decrease in the flow direction. As previously described, the decrease in cross section refers to the decrease in area as the flow path advances from the supply end hole 510 to the discharge end hole 540 along the flow path. The cross sections can decrease in the horizontal H direction, in the vertical V direction or in both. For the connector port shown in Figure 7, the cross section of the flow path of the connector port supply end 520 decreases in the vertical direction V and the two flow paths of the discharge port of the connector port 530a and 530b decrease in the horizontal direction H and vertical direction V.
    [0043] Converging flow paths, both in the connector port and in the dispensing element, are preferably smoothly converging, being that they converge continuously instead of intermittently converging along the flow path. This produces a uniform fluid flow field that exhibits a minimum pressure drop along the flow path in the flow direction with a maximum pressure drop occurring in the discharge end holes of the dispensing element. This helps to prevent build-ups when there is a greater chance of obstruction. The uniform fluid flow field also exhibits a continuous increase in speed, which results in non-stagnant or recirculating areas along the flow path, which reduces clogging and prevents the accumulation of bacteria, ensuring that the fluid that enters first, be the first to leave. In addition, due to the uniform flow field, the force required to drive the pump is reduced which results in a low application force on the actuator (button) required to dispense fluid during use, as well as reducing the need for priming the pump. . bomb
    [0044] The pump for shaving or shaving with liquid dispensing, according to the present invention, is a manually operated pump that can transport fluid by repeatedly pressing an actuator or button. An assembled view of a pump assembly 240 is illustrated in Figure 8. The pump assembly 240 includes a flexible tube 248 interposed between a first connector 242 and a second connector 244 and an actuator (button) 260 with each other. A first valve 250 is disposed on the first connector 242 and a second valve 252 is disposed on the second connector 244. The first fluid connector 242 includes a tip 243 that can pierce a frangible seal 238 in hole 232 of the fluid reservoir 230 to establish a fluid connection between pump 240 and fluid reservoir 230. The outer wall 245 of the first fluid connector 242 can be sealed against an inner wall 234 of fluid reservoir 230 to prevent fluid from flowing into cavity 208 of cable 200 Consequently, the fluid is directed into a hole 246 of the first fluid connector 242, which is in fluid communication with a pump assembly 240. The elongated resilient tube 248 pumps fluid from the fluid reservoir 230 through valves 250 and 252 to connector port 400.
    [0045] An actuator 260 (e.g., a button) facilitates pumping fluid from fluid reservoir 230 to connector port 400. For example, actuator 260 can compress resilient elastomeric tube 248 to open second valve 252 and release a predetermined dosage of fluid to the connector port 400. Actuator 260 can be released to return the resilient elastomeric tube 248 to its uncompressed state. As the resilient elastomeric tube 248 returns to its uncompressed state, the second valve 252 closes to prevent reflux of the fluid and the corresponding contamination associated with it and the first valve 250 opens, allowing the resilient elastomeric tube 248 to be filled with fluid for the next release by actuator 260. This is a repetitive process that is widely described below.
    [0046] As shown in Figure 8, the second connector 244 is coupled to the connector port 400 and is in liquid communication with it. For example, a first end 272 of the second connector 244 can be snapped into the supply end hole 410 of the connector port 400. The second connector 244 has a second end 274 with a hole 276 sized to receive the second valve 252. The second end 274 of the second connector 244 is coupled to the pump 240 and is in liquid communication with it. The elongated resilient tube 248 has a second end 264 connected to the second end 274 of the second connector 244. The second connector 244 includes a shoulder 256 to prevent the first end 272 of the second connector 244 from extending too far into the supply end hole. 410 of connector port 400. The resilient tube 248 has a first end 262 coupled to the first connector 242 and is in liquid communication with it. The first connector 242 can be semi-rigid and have a second end 282 snapped to the first end 262 of the resilient tube 248. The second end 282 of the first connector 242 has a hole 282 that extends through the first connector 242. Hole 286 is dimensioned to receive a first valve 250 (for example, a duckbill check valve). The first connector 242 can have a first end 280 snapped into the hole 232 of the reservoir 230. The first end 280 of the first connector 242 includes the tip 243 for drilling the frangible seal 238 into the hole of the reservoir 232. The first connector 242 includes a boss 266 to prevent the first end 280 of the first connector 242 from extending too far into the reservoir bore 232 and to prevent the second end 282 from extending too far into the resilient tube 248.
    [0047] Valves 250 and 252 can be one-way valves (for example, check valves, clack valves and non-return valves) that are connected in series. Examples of one-way valves that can be used include, but are not limited to, ball check valves, swing check valves or inclined disc check valves, block check valves, vertical displacement check valves and check valves. duckbill retention. Placing valves 250 and 252 within the first and second connectors 242, 244 saves space and also helps to prevent valves 250 and 252 from moving out of position.
    [0048] In certain embodiments, the actuator 260 can come into direct contact and compress the resilient tube 248. Figure 9 shows a cross section of an actuator 260 for a pump 240, according to the present invention. The lower portion 266 of the actuator 260 can be shaped to correlate with the internal contour of the cable cavity 208 and ideally curved from front to back to minimize stress on the resilient tube 248. Although the actuator can be positioned anywhere along of the length of the resilient tube 248 between the first and second valves 250, 252, it is preferably located in the center of the resilient tube 248.
    [0049] When pressed, the actuator 260 compresses the resilient tube 248 and opens the second valve 252, while the first valve 250 remains closed. The first and second cavities 250 and 252 can each have a flattened surface when closed. The flattened ends open to allow liquid to pass when pressure is applied and close to prevent backflow of liquid when pressure is removed (for example, when actuator 260 is released from resilient tube 248). The first valve 250 opens (and the second valve 252 closes) when the negative pressure is reached inside the resilient tube 248 (for example, when the actuator 260 is released and no longer compress the resilient tube 248, allowing it to return to the uncompressed state). Resilient properties (for example, elongation at break and hardness) and wall thickness can facilitate the return of the resilient tube 248 to its natural state and can reach negative pressure in the resilient tube 248. When the second valve 252 is closed and the first valve 250 is opened, the liquid can move from the reservoir 230, through the opening of the reservoir 234, through the first valve 250 and to the resilient tube 248. The positioning of a resilient tube 248 between a pair of unidirectional valves positioned in series prevents the reflux of shaving or hair removal residues and microbes into the pump 240 and reservoir 230. In certain embodiments, the resilient tube 248 can return the actuator 260 back to its original position. Consequently, an additional return force element (for example, a spring) is not necessarily necessary to return the actuator 260 back to its original position. The resilient tube 248 can be extruded or molded from materials having a Shore A hardness of about 40 to about 90 (ISO 868), including, but not limited to, thermoplastic elastomers (TPEs), polyvinyl chloride (PVC) , silicones, rubbers or any combination thereof. The resilient tube 248 can comprise a material having a tensile strength at break of about 8 MPa, 9 MPa or 10 MPa to about 12 MPa, 13 MPa or 14 MPa (ISO 37). The resilient tube 248 can comprise a material having a percentage elongation at break of about 300% mm2, 400% or 500% to about 600% mm2, 700% or 800% (ISO 37). The resilient tube 248 can have a nominal wall thickness of about 0.5 mm, 0.75 mm or 1 mm to about 1.25 mm, 1.5 mm or 2 mm to provide sufficient flexibility to allow efficient compression of the resilient tube 248 by actuator 260, but not so flexible that resilient tube 248 cannot return to its original position after being repeatedly compressed. Reservoir
    [0050] Cavity 208 includes a reservoir 230 that houses a fluid 210. Reservoir 208 can include a replaceable bottle. Figure 10 shows a reservoir 230 containing a fluid 210. Reservoir 230 includes an external container (231) that surrounds a retractable reservoir (233). The container 231 and the retractable reservoir 233 have aligned holes that together form a fluid outlet (235) through which fluid can exit the retractable reservoir (233) and the container (231). One or more orifices (237) in the container (231) allow air to flow into the container, thus allowing pressure compensation as the retractable reservoir (233) retracts. The reservoir shown in Figure 10 also includes a plurality of ribs 239 that delimit the lower end of container 231. Ribs 239 provide an outer surface that is easy to grip when removing container 231 from cavity 208 and provide a retractable accordion effect. during insertion of container 231 into cavity 208 and fluid outlet connection 235 from reservoir 230 to first connector 242 of pump 240. As the plurality of ribs retract, container 231 compresses the retractable reservoir 233 forcing fluid out of the reservoir 210 retractable 233 for the pump. This promotes priming of the pump 240, preparing it for use.
    [0051] A fluid 210 (for example, a lotion or gel) can be kept inside a fluid reservoir 230. The fluid reservoir 230 can be removed and replaced after the fluid is consumed. The cable 200 can define a cavity 208 configured to receive the fluid reservoir 230. In certain embodiments, the fluid reservoir 230 can be a vial or a delaminable sachet. In other embodiments, the fluid reservoir 230 may be a blow-molded or injection-molded plastic bottle.
    [0052] As shown in Figure 8 (previously described), the first connector 242 removably engages the fluid reservoir 230 to establish a fluid connection between the fluid reservoir 230 and the pump assembly 240. The outer wall 245 of the first fluid connector 242 can be sealed against an inner wall 236 of fluid reservoir 230 to prevent fluid from seeping into the cable cavity 208. first connector 242 includes a tip 243 configured to pierce a seal (238) of the fluid reservoir 230 to establish a fluid connection between pump assembly 240 and fluid reservoir 230. In certain embodiments, tip 243 can be chamfered and / or angled (for example, pyramidal, conical) to facilitate penetration of the seal.
    [0053] The container can have multiple chambers that allow fluids to mix upon dispensing. The fluid can include shaving or hair removal gels, shaving or hair removal foams, shaving or hair removal lotions, skin care compositions, conditioning aids, etc., which can be used to prepare the skin surface before blade contact with the skin. In addition, such materials may comprise beneficial agents suitable for the skin and / or hair that may be useful for a number of different desirable effects including exfoliation, refreshing, cleansing, hydrating, heating or thermogenic effects, conditioning and the like. Beneficial agents suitable for the skin and / or hair that can be included in the shaving or shaving fluid are disclosed in US Patent No. 6,789,321. For example, suitable agents include, but are not limited to, shaving or waxing soaps, lubricants, skin conditioners, skin moisturizers, hair conditioners, hair conditioners, fragrances, skin cleansing creams, bactericidal lotions or medicinal, blood coagulants, anti-inflammatories, astringents and combinations thereof. In certain embodiments, the fluid may be contained in a disposable or reusable bag, which is also contained within the cable cavity.
    [0054] The razor or epilator with liquid dispensing, according to the present invention, includes consumable cartridges that need to be replaced after various uses as a result of the loss of the blade's edge, the clogging of the dispensing element or both. However, the razor or epilator with liquid dispensing also includes fluid reservoirs that need to be replaced periodically. While disposable cartridges and replaceable fluid reservoirs can be packaged separately, they can also be packaged together and made available to consumers in a single package. For example, replaceable cartridges 610 and replaceable fluid reservoirs 620 can be packaged together in a blister pack 600, as shown in Figure 11. The number of replaceable cartridges and pack replaceable fluid reservoirs can be the same or different. However, without binding to any theory, replaceable fluid reservoirs may contain a volume of fluid that is correlated with the number of shaves or epilations per razor cartridge or epilator, so that the consumer replaces the razor cartridge. shave or shave while replacing the fluid reservoir.
