Abstract

A razor cartridge handle configured to be connected to first and second type razor cartridges, which first and second type razor cartridges are different from one another, is provided. The handle includes a cartridge end, a first assembly, a second assembly, an ejector, and a plunger. The first assembly is configured to connect the first type razor cartridge to a cartridge end of the handle. The second assembly is configured to connect the second type razor cartridge 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. The plunger is normally biased to a position where a distal end of the plunger is in contact with the attached razor cartridge.

First claim

What is claimed is:

1 . A razor cartridge handle configured to be connected to a first type razor cartridge, and configured to be connected to a second type razor cartridge, wherein the first type razor cartridge is different from the second type razor cartridge, the handle comprising:
a cartridge end and an opposed end; a first assembly configured to connect the first type razor cartridge to the cartridge end of the handle; and a second assembly configured to connect the second type razor cartridge to the cartridge end of the handle;
wherein the first and second assemblies are configured so that only a single razor cartridge can be attached to the handle at a time, which attached razor cartridge is either a first type razor cartridge or a second type razor cartridge;
an ejector button that is normally biased in a first position relative to the handle, and is translatable to an eject position; an ejector having a first arm with a distal end and a second arm with a distal end, which ejector is normally 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 razor cartridge; and a plunger with a distal end, which plunger is normally 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 razor cartridge.

2 . The razor cartridge handle of claim 1 , wherein the first assembly includes a body extending outwardly from the cartridge end of the handle, which body is configured to be received within a connecting member of the first type razor cartridge, which body includes a top panel spaced apart from an opposing bottom panel, and an end panel extending between the top and bottom panels, and the bottom panel includes a pair of tab slots; and
wherein the plunger and ejector arms are substantially disposed between the top and bottom panels.

3 . The razor cartridge handle of claim 2 , wherein the second assembly includes a top locating panel spaced apart from the body top panel, and a bottom locating panel spaced apart from the body bottom panel.

4 . The razor cartridge handle of claim 3 , wherein the second assembly further includes a wedge-shaped projection extending outwardly from the body end panel, which projection includes a pair of side walls and an end wall, and which side walls extend from the end wall to the body end panel converging toward one another.

5 . The razor cartridge of claim 4 , wherein at least a portion of the wedge-shaped projection is disposed between the ejector arms when the ejector arms are extended outwardly from the handle cartridge end, and the plunger is normally biased to extend outwardly from the end wall of the wedge-shaped projection.

6 . The razor cartridge of claim 1 , wherein the first assembly includes a body extending outwardly from the cartridge end of the handle, which body includes a top panel spaced apart from an opposing bottom panel, and an end panel extending between the top and bottom panels; and
the second assembly further includes a wedge-shaped projection extending outwardly from the body end panel, which projection includes a pair of side walls and an end wall, and which side walls extend from the end wall to the body end panel converging toward one another.

7 . The razor cartridge of claim 6 , wherein at least a portion of the wedge-shaped projection is disposed between the ejector arms when the ejector arms are extended outwardly from the handle cartridge end, and the plunger is normally biased to extend outwardly from the end wall of the wedge-shaped projection.

8 . The razor cartridge handle of claim 1 , wherein the distal end of the plunger is configured to engage a surface of a blade unit of the first type razor cartridge and a surface of a blade unit of the second type razor cartridge.

9 . The razor cartridge handle of claim 1 , wherein the distal ends of the ejector arms are configured to cooperate with features of a connecting member of the first type razor cartridge and also with features of a connecting member of the second type razor cartridge to allow the respective type razor cartridge to be removed from the present razor cartridge handle.

10 . A razor cartridge handle configured to be connected to a first type razor cartridge, and configured to be connected to a second type razor cartridge, wherein the first type razor cartridge is different from the second type razor cartridge, the handle comprising:
a first assembly configured to connect the first type razor cartridge to a cartridge end of the handle; and
a second assembly configured to connect the second type razor cartridge to the cartridge end of the handle;
wherein the first and second assemblies are configured so that only a single razor cartridge can be attached to the handle at a time, which attached razor cartridge is either the first type razor cartridge or the second type razor cartridge;
an razor cartridge ejector operable to selectively eject an attached first type razor cartridge and operable to selectively eject an attached second type razor cartridge; and
a plunger with a distal end, which plunger is normally biased to a position where the distal end of the plunger is in contact with the attached razor cartridge.

11 . The razor cartridge handle of claim 10 , wherein the first assembly includes a body extending outwardly from the cartridge end of the handle, which body is configured to be received within a connecting member of the first type razor cartridge, which body includes a top panel spaced apart from an opposing bottom panel, and an end panel extending between the top and bottom panels, and the bottom panel includes a pair of tab slots; and
wherein the ejector includes a first arm with a distal end and a second arm with a distal end; and
wherein at least a portion of the plunger and ejector arms are disposed between the top and bottom panels.

12 . The razor cartridge handle of claim 11 , wherein the second assembly includes a top locating panel spaced apart from the body top panel, and a bottom locating panel spaced apart from the body bottom panel.

13 . The razor cartridge handle of claim 12 , wherein the second assembly further includes a wedge-shaped projection extending outwardly from the body end panel.

14 . The razor cartridge of claim 13 , wherein at least a portion of the wedge-shaped projection is disposed between the ejector arms when the ejector arms are extended outwardly from the handle cartridge end, and the plunger is normally biased to extend outwardly from the wedge-shaped projection.

15 . The razor cartridge of claim 10 , wherein the first assembly includes a body extending outwardly from the cartridge end of the handle, which body includes a top panel spaced apart from an opposing bottom panel, and an end panel extending between the top and bottom panels; and
the second assembly further includes a wedge-shaped projection extending outwardly from the body end panel.

16 . The razor cartridge of claim 15 , wherein the ejector includes a first arm with a distal end and a second arm with a distal end, and at least a portion of the wedge-shaped projection is disposed between the ejector arms when the ejector arms are extended outwardly from
