Shaving razor with button
View Patent ↗A handle for a shaving razor includes a handle casing and an interconnect assembly disposed at an end of the handle casing. The interconnect assembly is configured to releasably connect a cartridge to the handle, and includes a release button comprising a button substrate and a flexible canopy extending outwardly from the button substrate toward the handle casing.
1. A handle for a shaving razor, the handle comprising:
a handle casing; and
an interconnect assembly disposed at an end of the handle casing, said interconnect assembly being configured to releasably connect a cartridge to the handle, and including a release button comprising a button substrate and a flexible canopy, comprising an elastomer, extending outwardly from the butt on substrate toward the handle casing;
the flexible canopy being constructed so that a free edge of the flexible canopy contacts a wall formed by the handle easing when the release button is in an unloaded position, and the flexible canopy buckles when the button substrate is moved towards the cartridge as a user actuates the release button, causing the free edge to move along the wall.
2. The handle of claim 1 , wherein the flexible canopy is constructed to recover, after buckling, toward an original, unloaded position.
3. The handle of claim 1 , wherein a contact angle between an outer surface of the canopy and the wall is no greater than about 110 degrees.
4. The handle of claim 1 , wherein a contact angle between an outer surface of the canopy and the wall varies along a periphery of the canopy.
5. The handle of claim 4 , wherein the contact angle varies from about 110 degrees to about 50 degrees.
6. The handle of claim 4 , wherein a maximum contact angle between the outer surface of the canopy and the wall is at a center region of the canopy.
7. The handle of claim 1 , wherein the canopy comprises a thermoplastic elastomer.
8. A shaving razor comprising:
a cartridge comprising a blade unit and connecting member pivotally connected to the blade unit, the blade unit including a housing that carries one or more shaving blades; and
a handle releasably connected to the cartridge, the handle including a release button comprising a button substrate and a flexible canopy, comprising an elastomer, extending outwardly from the button substrate;
the flexible canopy being constructed so that a free edge of the flexible canopy contacts a wall formed by the handle casing when the release button is in an unloaded position, and the flexible canopy buckles when the button substrate is moved towards the cartridge as a user actuates the release button, causing the free edge to move along the wall.
9. The handle of claim 1 wherein the canopy has a thickness between about 0.3 mm and about 0.6 mm.
10. The shaving razor of claim 8 , wherein the flexible canopy is constructed to recover, after buckling, toward an original, unloaded position.
11. The shaving razor of claim 8 , wherein a contact angle between an outer surface of the canopy and the wall is no greater than about 110 degrees.
12. The shaving razor of claim 8 , wherein a contact angle between an outer surface of the canopy and the wall varies along a periphery of the canopy.
13. The shaving razor of claim 12 , wherein the contact angle varies from about 110 degrees to about 50 degrees.
14. The shaving razor of claim 12 , wherein a maximum contact angle between the outer surface of the canopy and the wall is at a center region of the canopy.
15. The shaving razor of claim 8 , wherein the canopy comprises a thermoplastic elastomer.
16. The shaving razor of claim 8 wherein the canopy has a thickness between about 0.3 mm and about 0.6 mm.
