Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
65 words
In a make-up brush having a longitudinal axis and comprising: (a) shaft means; and (b) brush means having first and second ends and including means regularly distributed around said longitudinal axis of the brush to serve as bristles; the improvement comprising (c) means actuable by a user of the make-up brush for varying the brush diameter at least locally at said regularly distributed means thereof.
Claim 2
Dependent Claim
65 words
In a make-up brush having a longitudinal axis and comprising: (a) shaft means; and (b) brush means having first and second ends and including means regularly distributed around said longitudinal axis of the brush to serve as bristles; the improvement comprising (c) means actuable by a user of the make-up brush for varying the brush diameter at least locally at said regularly distributed means thereof.
Claim 3
Dependent Claim
36 words
A make-up brush according to claim 1, wherein said brush means is adapted to undergo deformation to vary in length so as to produce an increase in diameter simultaneous with decrease in length and vice versa.
Claim 4
Dependent Claim
22 words
A make-up brush according to claim 1, wherein the shaft is integral with means defining a closure for a make-up product container.
Claim 5
Dependent Claim
49 words
A make-up brush according to claim 2, wherein said brush means comprises several deformable longitudinal strips distributed around the longitudinal axis of the brush and separated from each other by gap means and wherein each said strip carries at least one row of bristles constituting said regularly distributed means.
Claim 6
Dependent Claim
40 words
A make-up brush according to claim 4, wherein said strips define a moulded sleeve with said gap means stopping short of first and second ends of the brush means; said strips being joined together at said first and second ends.
Claim 7
Dependent Claim
27 words
A make-up brush according to claim 3, wherein said brush means diameter varying means comprises actuation means capable of producing variation in length of said brush means.
Claim 8
Dependent Claim
70 words
A make-up brush according to claim 6, wherein said shaft means comprise a hollow shaft having first and second ends, and a rod sliding within said hollow shaft and having an end adapted to entrain said first end of said brush means, said second end being immobilised by said first end of said hollow shaft, and wherein said actuation means is effective to slide said rod along said hollow shaft.
Claim 9
Dependent Claim
51 words
A make-up brush according to claim 7, wherein said brush means is disposed between said first end of said hollow shaft and said end of the rod so as to be elastically compressed and deformed when said end of the rod is brought towards said first end of the hollow shaft.
Claim 10
Dependent Claim
31 words
A make-up brush according to claim 7, wherein said actuating means comprise a button means integral with said rod, and means allowing said rod to be maintained in alternative desired positions.
Claim 11
Dependent Claim
31 words
A make-up brush according to claim 8, wherein said actuating means comprise a button means integral with said rod, and means allowing said rod to be maintained in alternative desired positions.
Claim 12
Dependent Claim
203 words
A make-up brush having a longitudinal axis and comprising (a) brush means having first and second ends and comprising a plurality of deformable longitudinal strips distributed around the longitudinal axis of said make-up brush and separated from each other by gap means, each said strip carrying at least one row of bristles, said brush means being adapted to undergo deformation to vary in length so as to produce an increase in diameter simultaneous with a decrease in length and vice versa; (b) hollow shaft means having first and second ends and a rod slidable within said hollow shaft, said rod having an end adapted to entrain said first end of said brush means, said second end of said brush means being immobilized by said first end of said hollow shaft whereby said brush means is disposed between said first end of said hollow shaft and said rod end so as to be elastically compressed and deformed when said rod end is brought towards said first end of said hollow shaft; and (c) actuation means capable of producing variation in length of said brush means comprising button means integral with said rod and means allowing said rod to be maintained in alternative desired positions.
Claim 13
Dependent Claim
203 words
A make-up brush having a longitudinal axis and comprising (a) brush means having first and second ends and comprising a plurality of deformable longitudinal strips distributed around the longitudinal axis of said make-up brush and separated from each other by gap means, each said strip carrying at least one row of bristles, said brush means being adapted to undergo deformation to vary in length so as to produce an increase in diameter simultaneous with a decrease in length and vice versa; (b) hollow shaft means having first and second ends and a rod slidable within said hollow shaft, said rod having an end adapted to entrain said first end of said brush means, said second end of said brush means being immobilized by said first end of said hollow shaft whereby said brush means is disposed between said first end of said hollow shaft and said rod end so as to be elastically compressed and deformed when said rod end is brought towards said first end of said hollow shaft; and (c) actuation means capable of producing variation in length of said brush means comprising button means integral with said rod and means allowing said rod to be maintained in alternative desired positions.
