Abstract

A safety razor handle in combination with a razor cartridge that is one of a first and second type razor cartridge, each with a respective connecting member, which first and second type razor cartridge connecting members are different from one another, is provided. The handle includes a cartridge end, a first assembly, a second assembly, and an ejector. The first assembly is configured to connect the first type razor cartridge's connecting member to a cartridge end of the handle. The second assembly is configured to connect the second type razor cartridge's connecting member to the cartridge end of the handle. The razor cartridge ejector is operable to selectively eject both first type razor cartridges and second type razor cartridges from the handle.

First claim

What is claimed is:

1 . A combination of a safety razor handle and a razor cartridge, comprising:
a razor cartridge handle configured to be connected to a first type razor cartridge having a first type razor cartridge connecting member, and configured to be connected to a second type razor cartridge having a second type razor cartridge connecting member, wherein the first type razor cartridge connecting member is different from the second type razor cartridge connecting member, the handle comprising: a cartridge end and an opposed end; a first group of panels at the cartridge end configured to connect the first type razor cartridge connecting member to the cartridge end of the handle, the first group of panels including a body extending outwardly from the cartridge end of the handle, the body including a body first panel spaced apart from an opposing body second panel, and an end panel extending between the body first and second panels; a second group of panels at the cartridge end configured to connect the second type razor cartridge connecting member to the cartridge end of the handle, the second group of panels including a first locating panel spaced apart from the body first panel; wherein the first and second groups of panels are configured so that only a single razor cartridge can be attached to the handle at a time, the attached razor cartridge being either a first type razor cartridge or a second type razor cartridge; and the first type razor cartridge connected to the handle such that the body is received within a cavity of the first type razor cartridge connecting member and a first side wall of the connecting member is received in a gap between the first locating panel and the body first panel.

2 . The combination of claim 1 , wherein the second group of panels includes a second locating panel spaced apart from the body second panel and a second side wall of the connecting member is received in a gap between the second locating panel and the body second panel.

3 . The combination of claim 1 , wherein the handle further comprises an ejector button at the cartridge end of the handle that is normally configured to be biased in a first position relative to the handle, and is translatable to an eject position and an ejector having a first arm with a distal end and a second arm with a distal end, the ejector arms being substantially disposed between the body first and body second panels, the ejector being normally configured to be biased in a retracted position;
wherein the ejector is in communication with the ejector button such that translating the ejector button to the eject position causes the ejector arms to extend outwardly from the handle cartridge end and causes the distal ends of the ejector arms to contact the attached first type razor cartridge.

4 . The combination of claim 1 , wherein the handle further comprises a plunger with a distal end, the plunger being normally configured to be biased outwardly from the handle cartridge end to reside in an extended position;
wherein in the extended position the distal end of the plunger is in contact with the attached first type razor cartridge; and wherein the plunger is substantially disposed between the body first and second panels.

5 . The combination of claim 4 , wherein the distal end of the plunger engages a surface of a blade unit of the first type of razor cartridge.

6 . The combination of claim 1 , wherein the handle further comprises laterally opposed stabilizing projections disposed externally of the first type razor cartridge connecting member.

7 . The combination of claim 1 , wherein a second side wall of the first type razor cartridge connecting member opposed the first side wall includes a pair of tabs engaged in a one of a respective pair of tab slots the body second panel.

8 . A combination of a safety razor handle and a razor cartridge, comprising:
a razor cartridge handle configured to be connected to a first type razor cartridge having a first type razor cartridge connecting member, and configured to be connected to a second type razor cartridge having a second type razor cartridge connecting member, wherein the first type razor cartridge connecting member is different from the second type razor cartridge connecting member, the handle comprising: a cartridge end and an opposed end, a first group of panels at the cartridge end configured to connect the first type razor cartridge connecting member to the cartridge end of the handle, the first group of panels including a body extending outwardly from the cartridge end of the handle, the body including a body first panel spaced apart from an opposing body second panel, and an end panel extending between the body first and second panels, a second group of panels at the cartridge end configured to connect the second type razor cartridge connecting member o the cartridge end of the handle, the second group of panels including a first locating panel spaced apart from the body first panel;
wherein the first and second groups of panels are configured so that only a single razor cartridge can be attached to the handle at a time, the attached razor cartridge being either a first type razor cartridge or a second type razor cartridge; and
the second type razor cartridge connected to the handle such that the first locating panel is received within a cavity of the second type razor cartridge connecting member.

9 . The combination of claim 8 , wherein the second locating panel is received within the cavity of second type razor cartridge connecting member.

10 . The combination of claim 8 , wherein at least one of the first and the second locating panels includes an outwardly extending tab and the tab is received in a respective tab slot of the second type razor cartridge connecting member.

11 . The combination of claim 8 , wherein the handle further comprises an ejector button at the cartridge end of the handle that is normally configured to be biased in a first position relative to the handle, and is translatable to an eject position and an ejector having a first arm with a distal end and a second arm with a distal end the ejector arms being substantially disposed between the body first and body second panels, the ejector being normally configured to be biased in a retracted position wherein the arms substantially reside within the handle; wherein the ejector is in communication with the ejector button such that translating the ejector button to the eject position causes the ejector arms to extend outwardly from the handle cartridge end and causes the distal ends of the ejector arms to contact the attached second type razor cartridge.

12 . The combination of claim 8 , wherein the handle further comprises a plunger with a distal end, the plunger being normally configured to be biased outwardly from the handle cartridge end to reside in an extended position, wherein in the extended position the distal end of the plunger is in contact with the attached second type razor cartridge; and wherein the plunger is substantially disposed between the body first and second panels.

13 . The combination of claim 12 , wherein the distal end of the plunger engages a surface of a blade unit of the second type of razor cartridge.

14 . The combination of claim 8 , wherein the handle further comprises laterally opposed stabilizing projections received within the cavity of the second type razor cartridge connecting member.

15 . The combination of claim 8 , wherein the body further includes a wedge-shaped projection extending outwardly from the body end panel, the projection including a pa
