Handheld, personal skin care systems with detachable skin care elements
View Patent ↗A skin care element holder for use with a handheld body having a receptacle includes a substantially circular plate having a diameter between about 20 and about 60 mm. The substantially circular plate has a first surface for coupling to the skin care element; a second surface; and an outer peripheral edge. The second surface of the substantially circular plate has at least one spacer leg; a plurality of engagement arms; and at least one key. Each of the at least one spacer leg, engagement arms and key extend from the second surface in a direction away from the first surface. The at least one spacer leg supports the plate in the receptacle. At least one of said engagement arms includes a snap-fit projection for engagement with a recess in the receptacle. The key is arranged and configured to fit into a notch in the receptacle.
1. A skin care element holder for use with a handheld body having a receptacle, said skin care element holder comprising a substantially circular plate having a diameter between about 20 and about 60 mm, wherein:
a. said substantially circular plate has:
i. a first surface arranged and configured for coupling to a skin care element;
ii. a second surface, opposite said first surface; and
iii. an outer peripheral edge; and
b. said second surface of said substantially circular plate has:
i. at least one spacer leg extending from said second surface in a direction away from said first surface to support said plate in the receptacle;
ii. a plurality of engagement arms extending a first distance from said second surface in a direction away from said first surface, at least one of said engagement arms comprising a snap-fit projection for engagement with a recess in the receptacle; and
iii. at least one key extending a second distance from said second surface in a direction away from said first surface, said key being arranged and configured to fit into a notch in the receptacle, wherein said key comprises at least one raised portion extending radially inward from an outer perimeter of said plate;
wherein said first distance is greater than said second distance.
2. The skin care element holder of claim 1 , wherein the skin care element is a disposable element and is removably coupled to said first surface of said substantially circular plate.
3. The skin care element holder of claim 1 , wherein the skin care element is a durable element and is permanently coupled to said first surface of said substantially circular plate.
4. The skin care element holder of claim 1 , wherein said outer peripheral edge of said substantially circular plate is the outer circumference of a circle.
5. The skin care element holder of claim 1 , wherein said outer peripheral edge of said substantially circular plate comprises a resilient material.
6. The skin care element holder of claim 1 , wherein said substantially circular plate is free of discontinuities along said outer peripheral edge.
7. The skin care element holder of claim 1 , wherein:
said spacer leg extends a third distance from said second surface in a direction away from said first surface; and
said first distance is greater than said third distance.
8. The skin care element holder of claim 7 , wherein said third distance is greater than said second distance.
9. A skin care element holder for use with a handheld body having a receptacle, said skin care element holder comprising a substantially circular plate having a diameter between about 20 and about 60 mm, wherein:
a. said substantially circular plate has:
i. a first surface arranged and configured for coupling to the skin care element;
ii. a second surface, opposite said first surface; and
iii. an outer peripheral edge; and
b. said second surface of said substantially circular plate has:
i. at least one spacer leg extending from said second surface in a direction away from said first surface to support said plate in the receptacle;
ii. a plurality of engagement arms extending from said second surface in a direction away from said first surface, at least one of said engagement arms comprising a snap-fit projection for engagement with a recess in the receptacle; and
iii. at least one key extending from said second surface in a direction away from said first surface, said key being arranged and configured to fit into a notch in the receptacle, wherein said key comprises at least one raised portion having a longitudinal axis extending radially inward from an outer perimeter of said plate.
10. The skin care element holder of claim 9 , wherein:
said key has an engagement surface along a free end of said at least one raised portion furthest from said second surface and extending along said longitudinal axis, said engagement surface being configured to engage the notch in the receptacle of the handheld body; and
said snap-fit projection engages in the recess in the receptacle of the handheld body in a radial direction.
11. The skin care element holder of claim 9 , wherein said substantially circular plate is free of discontinuities along said outer peripheral edge.
12. The skin care element holder of claim 9 , wherein said key extends radially beyond said engagement arms and up to said outer peripheral edge of said plate.
