• a threaded rod 208 extends downward from the cap 202 so as to rotate upon rotation of the cap.
• an abutment element 210 is threadedly engaged on the rod 208. Rotation of the cap 202 causes the element 210 to advance along the threaded rod 208. Referring to Figs. 14 and 15, the abutment element 210 is prevented from rotating by abutment element lugs or protrusions 218 that extend radially from the element 210 and that engage in guide channels 212 within the body 206.
• a resilient annular sleeve 211 is seated and retained between the base 204 and the body 206 and has an inner diameter that is smaller than the inner diameter of the opening 224.
• the sleeve 211 is provided for sealing the cavity 222 against the ingress of water when a bar of hygiene product in provided in the cavity 222.
• a user introduces a bar of product 214 into cavity 222 through an opening 224 in the base.
• a bar of hygiene product 214 for use with the implement includes a hollow center 216 for receiving the threaded rod 208.
• the user urges the bar against a resilient silicone sleeve 211 that assists in retaining the bar in the refillable implement.
• the resiliency of the sleeve 211 allows the correspondingly shaped bar of product 214 to be retained in the opening of the annulus of the sleeve and to slide against the sleeve through the opening 224 of the body 206.
• the cap 202 When the cap 202 is rotated to thereby rotate the threaded rod 208 and to urge the abutment element 210 to progress downwardly along the threaded rod, the abutment element 210 abuts and presses against the bar of product to urge it downward along the cavity and to protrude from the opening 224 of the base 204.
• the user may twist the cap to urge the bar downward to present more of the bar to the contact area where the product is to be applied.
• the base 204 which is threadedly engaged with the implement body 206, may be removed so that the bar of product 214 can be replaced with a new bar.
• the resilient silicone sleeve 211 is provided about the opening 224 to retain the hygiene product within the cavity 222.
• An inner lip 226 of the base 204 has a diameter that is smaller than the diameter of the base opening 224 to assist in retaining the hygiene product 214 in the cavity 222.
• the sleeve 211 is sandwiched between the lip 226 of the base 204 and the implement body 206.
• the resilient annular silicone sleeve 211 may be in the form of a flat ring form to surround and maintain a hold on the stick of a hygiene product.
• the resiliency of the sleeve allows it to deform and increase its diameter when loading a bar of product through it. As the diameter of the bar reduces with usage, the sleeve may contract around the bar to continue retaining it in place. The sleeve also continues to seal the cavity 222 against the ingress of water.
• the present invention is suitable for dispensing implements for dispensing refillable personal hygiene products in a stick form.
• Example products include, but are not limited to, skin, body, beauty, and personal care products, such as soap, deodorant, sunscreen, lip balm, makeup, and topical medications.
• a refillable implement 300 according to a helical cylinder embodiment of the invention is generally depicted in Figs. 20-24. According to this embodiment, the bar of product is retained in a hollow helically grooved cylinder used to progress the bar of product downward.
• the refillable implement 300 comprises a cap 302, a base 304 and an implement body 306 to hold and retain a bar of a hygiene product 314.
• the cap 302 includes one or more notches 318 on its inner wall for engaging with one or more locking ribs 319 of a hollow cylinder 308. This allows the cylinder 308 to be rotated by rotating the cap 302.
• the cylinder 308 is defined by two helical members 312, 313 with helical grooves 320, 321 between them, the grooves being radially opposed to one another such that they are out of phase by 180° about the circumference of the cylinder.
• an abutment element 310 is engaged in radially opposed portions of the grooves 320 and 321.
• Rotation of the cap 302 causes the abutment element 310 to progress along the grooves 320, 321.
• the abutment element 310 is constrained against simply rotating with the cylinder 308 by lug extensions 329, 330 that project through the grooves 320, 321 and engage in opposed channels 331 , 332 formed in the body 306 of the implement.
• the channels 331 , 332 extend parallel to the longitudinal axis of the cylinder.
• the edges of the helical members 312, 313 push against the lug extensions 329, 330 causing the abutment element 310 to migrate along the channels 331 , 332 and along the length of the cylinder.
• the abutment element 310 pushes the stick of hygiene product 214 to urge it toward the base 304 and to thereby be exposed to the surface being treated.
• a retaining member 323 may engage the lower ends of the two members 312, 313 to interlock them so that they rotate in synchronization with one another and to provide a more rigid cylinder 308.
• a user introduces the bar of hygiene product 314 into the cavity 322 of the implement body 306 by unscrewing the threaded base 304, then urging the bar against a resilient silicone sleeve 311 to retain the bar in the body 306.
• the base 304 may be disconnected from the body 306 so that the bar of hygiene product 314 can be replaced with a new bar.
• the sleeve 311 is in the form of a hollow cylindrical portion 316 having a flange or rim 315 that is clamped between the inner lip 226 of the base 204 and the implement body 206.
• the hollow cylindrical portion 316 extends downward from the rim 315.
• the bottom of the cylindrical portion 316 is partially closed to present a central opening 317 through which the bar of product protrudes.
• the resiliency of the sleeve 311 allows the sides of the opening 317 to grip the side or sides of the bar of product to seal it against the ingress of water.
