Definitions
- This disclosure relates generally to wet shaving devices, and more specifically to safety razors having a dispensing head in fluid communication with a reservoir of a flowable shaving aid material and a removable shield therebetween.
- the flowable shaving aid material can replace a customary shaving preparation or can be used in addition thereto.
- the reservoir is in fluid communication with a dispensing head to deliver the shaving aid material to the skin surface of a user during a normal shaving operation.
- the dispensing head can include a valve arrangement to regulate the flow of the shaving aid material and the dispensing head can be integral with the razor cartridge or situated adjacent thereto.
- Several different types of dispensing head have been proposed, including those utilizing a capillary wick, e.g. as disclosed in U.S. Patent number 5,134,775 to Althaus et al. and an array of apertures, valves or rollers that partially or completely surround the cutting edge(s), e.g. as disclosed respectively in U.S. Patents number 7,137,203 to Bressler et al., 7,043,841 to Franzini et al. and U.S. Patent application publication 2005/0138814.
- dispensing heads of e.g. the aforementioned '775 or '841 patents or the '814 application have generally non-flat skin contacting surfaces of their dispensing heads due to the nature of the capillary wick or the presence of protruding valves or rollers.
- adhering a removable tape to such non-flat surfaces provides manufacturing challenges.
- any reaction between the shaving aid material and an adhesive coating of the removable tape can result in a reduction of adhesiveness.
- a replacement cartridge for such a razor assembly comprises a reservoir adapted to contain the flowable shaving aid material, a dispensing head adapted to deposit the flowable shaving aid material on a skin surface of a user during a normal shaving operation and a removable shield disposed between the reservoir and the dispensing head adapted to prevent flow of the shaving aid material the reservoir until the shield is removed.
- a removable shield disposed between the reservoir and the dispensing head adapted to prevent flow of the shaving aid material the reservoir until the shield is removed.
- a portion of the shield extends outwardly from an opening in a slot or gap between the reservoir and the dispensing head to provide a region that can be gripped by the user for removal of the shield. Removal of the shield is a onetime event.
- the shield can be integrally formed with a plug and can include a weakened portion, e.g. a notch or a series of perforations therebetween. Application of a predetermined force by the user can cause the shield to separate from the plug in the region of the weakened portion. After separation, the plug is retained in the replacement cartridge and can substantially close the opening of the slot to prevent undesirable flow of the shaving aid material out of the opening.
- the replacement cartridge can include a spring or springs to provide an attractive force between the reservoir and the dispensing head.
- the spring or springs can be e.g. a helical spring or leaf spring, such as a cantilevered beam that is preferably integrally formed with either the reservoir or the dispensing head.
- a shield disposed between the reservoir and the dispensing head prevents flow of the shaving aid material from the reservoir until the shield is removed.
- the attractive force between the reservoir and the dispensing head closes a gap between the reservoir and the dispensing head to provide fluid communication as previously described and to prevent undesirable flow of the shaving aid material from end(s) of the gap.
- the shield is preferably a die-cut biaxiallyoriented polyethylene terephthalate (boPET) polyester film or other suitable film or can be injection molded or extruded from other suitable thermoplastic materials.
- the replacement cartridge can include a razor cartridge disposed adjacent the dispensing head.
- the housing of the dispensing head housing can be integrally formed with the housing of the razor cartridge.
- Embodiments of the present disclosure can include one or more of the following advantages.
- the razor will largely resist changes in meteorological conditions and retain its attractiveness to a potential purchaser.
- the shield provides a "freshness" indicator to the user.

- Fig. 7C is an alternate embodiment to that of Figs 7A and 7B having a different spring arrangement.
- an exemplary razor assembly 10 comprising a handle 12 and a replacement cartridge 14.
- the replacement cartridge 14 is shown partially disassembled from the handle 12 purely for convenience of illustration.
- the replacement cartridge 14 comprises a reservoir 20 adapted to contain a flowable shaving aid material that can be as known in the art and a dispensing head 30 adapted to deposit the flowable shaving aid material on a skin surface of a user during a normal shaving operation.
- a removable shield 40 having a user grippable portion 42 is disposed at an interface region 22 between the reservoir and the dispensing head.
- the dispensing head 30 includes a plurality of ports, valves or wicks 32, or combinations thereof, to regulate the flow of shaving aid material during use.
- These ports, valves or wicks can be as disclosed in U.S. Patents number 5,134,775 to Althaus et al., 7,137,203 to Bressler et al., 7,043,841 to Franzini et al. and U.S. Patent application publication 2005/0138814, the disclosures of which are hereby incorporated by reference in their entireties.
- the ports, valves or wicks 32 can be disposed to partially or completely surround cutting edges 52 of a razor cartridge 50.
- FIG. 2A an embodiment of a replaceable cartridge 60 generally as previously described, is depicted having a dispensing head 62 disposed adjacent a razor cartridge 64.
- a reservoir 66 is connected to the dispensing head and a shield 68 is disposed therebetween as will be discussed later in the present disclosure.
- FIG. 2B another embodiment of a replaceable cartridge 70 is depicted having a dispensing head 72, a reservoir 76 connected to the dispensing head and a shield 78 disposed therebetween.

- a notch 110 is provided as a so-called stress concentration that will act as an initiation site for a tear to separate the shield from the plug.
- Fig. 5B a series of perforations 112 are provided, preferably extending across the width of the shield.
- the shield is preferably manufactured from a polyester film, most preferably biaxiallyoriented polyethylene terephthalate (boPET) polyester which is readily commercially available under a number of different trade names including MYLAR and MELINEX provided by the DUPONT Company. This material is preferred due to a preferred combination of several properties such as strength, chemical stability and barrier properties. However other film materials can also be provided.
- the shield is preferably about 0.1mm thick and is preferably manufactured by die-cutting.
- the shield can also be manufactured by e.g. injection molding or extrusion processes in which case the thickness and material can be altered to suit the chosen process.
- FIG. 4 an exaggerated schematic partial cross section taken on lines 4-4 of Fig. 2 is depicted showing a slot 120 in the vicinity of an interface between the reservoir 122 and the dispensing head 124.
- One or more channels 126 are included in both the housings of the reservoir and dispensing head to provide fluid communication therebetween when the shield 128 is removed by a user by gripping the shield by a grippable portion 130 that extends outwardly from an opening 132 of the slot 120 and applying a predetermined force in an approximately horizontal leftward direction relative to the depicted figure.
- the clearances between the component parts are shown enlarged purely for clarity of depiction.
- the clearances are preferably sized such that no flowable shaving aid material will pass from the reservoir to the dispensing head or out of the opening until the shield is operated by the application of the aforementioned predetermined force.
- FIG. 6A this embodiment is generally similar to the depiction of Fig. 4 with the exception that the shield 148 preferably of the type of Figs. 5A and 5B is disposed between the reservoir and dispensing head in a U-shape and with the plug 146 preferably bonded (e.g. by a suitable adhesive or ultrasonic welding or mechanically attached) to one housing in the region 147.
