Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
91 words
A composite hand held personal test device comprising a support member carrying a plurality of receptacles for containing liquid materials, each said receptacle having a body portion and a nipple portin, said receptacles being arranged about said support member in arcuate array and a cooperating cutting element, said support member and said cutting element being relatively rotatable about a common axis whereby said cutting element is operable to shear said nipple portion from the body portion of each receptacle to release liquid from each receptacle in sequence as relative rotation occurs.
Claim 2
Dependent Claim
91 words
A composite hand held personal test device comprising a support member carrying a plurality of receptacles for containing liquid materials, each said receptacle having a body portion and a nipple portin, said receptacles being arranged about said support member in arcuate array and a cooperating cutting element, said support member and said cutting element being relatively rotatable about a common axis whereby said cutting element is operable to shear said nipple portion from the body portion of each receptacle to release liquid from each receptacle in sequence as relative rotation occurs.
Claim 3
Dependent Claim
29 words
The device of claim 1 in which said cutting element is provded with a slot to receive and to provide clearance for said nipples as said relative rotation occurs.
Claim 4
Dependent Claim
34 words
The device of claim 2 which said slot is arcuate and registers with the arcuate array of said receptacles so that all said nipples are received in said slot before said relative rotation occurs.
Claim 5
Dependent Claim
25 words
The device of claim 2 in which said cutting element comprises a disc and includes a cutting edge disposed at one end of said slot.
Claim 6
Dependent Claim
24 words
The device of claim 4 in which the disc includes a support element operable to receive a test specimen located adjacent said cutting edge.
Claim 7
Dependent Claim
13 words
The device of claim 5 in which said support element comprises a membrane.
Claim 8
Dependent Claim
11 words
The device of claim 6 in which said membrane is permeable.

Claim 11
Dependent Claim
44 words
The device of claim 9 in which one of said first housing member and said second housing member includes first detent means cooperating with second detent means on said disc for retaining said disc releasably in a predetermined position relative to said housing members.
Claim 12
Dependent Claim
44 words
The device of claim 10 in which the first and second detent means are so positioned as to be operable to register said support element releasably in alignment with a sheared receptacle whereby liquid material released from said receptacle flows onto said support element.
Claim 13
Dependent Claim
54 words
The device of claim 10 in which said first detent means are arrayed arcuately and in radial alignment with said receptacles so as to position the support element releasably in register with each receptacle in sequence following shearing action whereby the liquid material from each receptacle flows onto the support element sequentially and individually.
