Abstract

A method for assembling a razor handle is provided. The method includes installing a rod into a first shell of a body of a razor handle, installing an attachment end of a head onto a front end of the first shell, installing a clip member onto a rear end of the first shell, positioning a second shell adjacent to the first shell, compressing the first shell and the second shell together, and covering the first and second shell with a cover layer. The clip member includes retention features to facilitate coupling to the first and second shells. The cover layer can entirely surround the first and second shells, can be overmolded on both shells, and can be formed of thermoplastic elastomer with a durometer value of between about 15 and about 20. The thermoplastic elastomer is substantially translucent or less opaque than the first and second shell.

Claims (21)

1. A method for assembling a razor handle, the method comprising:

installing a rod into a first shell of a body of a razor handle,

installing an attachment end of a head onto a front end of the first shell, said attachment end disposed on an end of said head proximal to said rod;

installing a clip member onto a rear end of the first shell;

positioning a second shell adjacent to the first shell;

compressing the first shell and the second shell together; and covering the first and second shell with a cover layer,

wherein covering the first and second shells with a cover layer comprises extending the cover layer into through holes defined by the first and second shells.

2. The method of claim 1 , wherein installing the attachment end of the head comprises aligning a protrusion on a stem of the attachment end with a slot defined by the first shell.

3. The method of claim 1 , wherein installing the attachment end of the head comprises aligning a post on a stem with a through hole defined by the first shell.

4. The method of claim 1 , wherein installing the clip member onto the rear end of the first shell comprises compressing the clip member such that a first retention feature on the clip member engages a second retention feature on the first shell to facilitate coupling of the clip member to the first shell.

5. The method of claim 1 , wherein compressing the first shell and the second shell together comprises engaging a first retention feature on the clip member with a second retention feature on each of the first and second shells to facilitate coupling of the clip member to the first and second shells.

6. The method of claim 1 , wherein:

installing the attachment end of the head comprises aligning a protrusion on a stem with a slot defined by the first shell; and

positioning the second shell adjacent to the first shell comprises aligning the protrusion with a slot defined by the second shell.

7. The method of claim 6 , wherein compressing the first shell and the second shell together comprises inserting first posts on the attachment end of the head into the respective through holes defined by the first shell and inserting second posts on the attachment end of the head into respective through holes define by the second shell.

8. The method of claim 7 , wherein compressing the first shell and the second shell together further comprises pushing an enlarged portion of a distal end of each of the first and second posts through the respective through holes of the first shell and the second shell to facilitate frictional engagement therebetween.

9. The method of claim 1 , wherein covering the first and second shell with a cover layer comprises covering the first and second shells with a cover layer formed of thermoplastic elastomer.

10. The method of claim 9 , wherein the thermoplastic elastomer has a durometer value of between about 15 and about 20.

11. The method of claim 10 , wherein the thermoplastic elastomer is substantially translucent.

12. The method of claim 11 , wherein the thermoplastic elastomer is less opaque than the first and second shell.

13. The method of claim 1 , wherein covering the first and second shells with a cover layer comprises overmolding the cover layer on the first and second shells.
