Abstract
Abstract The ejecting member is interposed between two blade elements of a two-edge shaving blade unit in a manner to be retractably moved forwardly to eject shaved hair particles and other matters deposited in and clogging the space between the cutting edges of two blade elements. The ejecting member has an integral construction which includes an outer frame portion defining the outer profile of the ejecting member, a substantially quadrilateral aperture having at least one discontinuity and defining at its outer sides the inner edges of the outer frame portion, an inner island portion fixedly cramped between two blade elements and defined by the inner sides of the aperture, and a resilient bridge portion constituted by the discontinuity of the aperture and resiliently connecting the inner island portion to the outer frame portion. The outer frame portion may be moved resiliently to eject the shaved hair particles or the like, when it is pressed forwardly while the inner island portion is unmovably cramped between the blade elements, thanks to the resiliency of the resilient bridge portion.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
149 words
An ejecting member adapted to be interposed between two blade elements of a two-edge shaving blade unit and to be retractably moved forwardly to eject shaved hair particles and other matters deposited in and clogging the space between the cutting edges of said blade elements, the improvement wherein said ejecting member has an integral tabular construction including an outer frame portion which defines the outer profile of said ejecting member, an aperture which defines at its outer sides the inner edges of said outer frame portion, an inner island portion defined by the inner sides of said aperture and adapted to be fixedly cramped between said upper and lower blade elements, and at least one resilient bridge portion by which said inner island portion is resiliently connected to said outer frame portion, wherein said outer frame portion and said resilient bridge portion are thinner than said inner island portion.
Claim 2
Dependent Claim
149 words
An ejecting member adapted to be interposed between two blade elements of a two-edge shaving blade unit and to be retractably moved forwardly to eject shaved hair particles and other matters deposited in and clogging the space between the cutting edges of said blade elements, the improvement wherein said ejecting member has an integral tabular construction including an outer frame portion which defines the outer profile of said ejecting member, an aperture which defines at its outer sides the inner edges of said outer frame portion, an inner island portion defined by the inner sides of said aperture and adapted to be fixedly cramped between said upper and lower blade elements, and at least one resilient bridge portion by which said inner island portion is resiliently connected to said outer frame portion, wherein said outer frame portion and said resilient bridge portion are thinner than said inner island portion.
Claim 3
Dependent Claim
26 words
An ejecting member as claimed in claim 1, wherein said outer frame portion has a substantially rectangular form, while said aperture has a generally quadrilateral shape.
Claim 4
Dependent Claim
24 words
An ejecting member as claimed in claim 1 or 2, wherein said aperture has at least one discontinuity which constitutes said resilient bridge portion.
Claim 5
Dependent Claim
20 words
An ejecting member as claimed in claim 1 or 2, wherein the number of said resilient bridge portion is two.
Claim 6
Dependent Claim
35 words

Claim 7
Dependent Claim
149 words
A two-edge shaving blade unit comprising an ejecting member interposed between two blade elements of said blade unit to be retractably moved forwardly to eject shaved hair particles and other matters deposited in and clogging the space between the cutting edges of said blade elements, the improvement wherein said ejecting member has an integral tabular construction including an outer frame portion which defines the outer profile of said ejecting member, an aperture which defines at its outer sides the inner edges of said outer frame portion, an inner island portion defined by the inner sides of said aperture and adapted to be fixedly cramped between said upper and lower blade elements, and at least one resilient bridge portion by which said inner island portion is resiliently connected to said outer frame portion, wherein said outer frame portion and said resilient bridge portion are thinner than said inner island portion.
Claim 8
Dependent Claim
149 words
A two-edge shaving blade unit comprising an ejecting member interposed between two blade elements of said blade unit to be retractably moved forwardly to eject shaved hair particles and other matters deposited in and clogging the space between the cutting edges of said blade elements, the improvement wherein said ejecting member has an integral tabular construction including an outer frame portion which defines the outer profile of said ejecting member, an aperture which defines at its outer sides the inner edges of said outer frame portion, an inner island portion defined by the inner sides of said aperture and adapted to be fixedly cramped between said upper and lower blade elements, and at least one resilient bridge portion by which said inner island portion is resiliently connected to said outer frame portion, wherein said outer frame portion and said resilient bridge portion are thinner than said inner island portion.
Claim 9
Dependent Claim
28 words
