Abstract
Abstract There is described a container used to extract antigens for an immunoassay, having a wall means defining open and closed opposite ends. The container is provided with dividing members located in the closed end of the container which divides the volume of the closed end into at least two separate regions. A portion of the container's wall means adjacent to the closed end is shaped and sized to cooperate with a depositing device to ensure that separate reagents are separately deposited on opposite sides of the dividing members.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
133 words
A container useful for extracting antigens, comprising: A. wall means defining open and closed opposite ends, a portion of said wall means defining said closed end being flexible enough to permit squeezing; B. dividing means located in the closed end of the container for dividing the volume of said closed end into at least two separate regions; a portion of said wall means adjacent to said closed end being shaped and sized to cooperate with a depositing means to ensure separated deposit of reagents on opposite sides of said dividing means, and further comprising C. means mounted on the closed end of the container extending from said closed end, for protecting the container from shock and subsequent dislodging of dried reagents located in said separate regions of said closed end of the container.
Claim 2
Dependent Claim
133 words
A container useful for extracting antigens, comprising: A. wall means defining open and closed opposite ends, a portion of said wall means defining said closed end being flexible enough to permit squeezing; B. dividing means located in the closed end of the container for dividing the volume of said closed end into at least two separate regions; a portion of said wall means adjacent to said closed end being shaped and sized to cooperate with a depositing means to ensure separated deposit of reagents on opposite sides of said dividing means, and further comprising C. means mounted on the closed end of the container extending from said closed end, for protecting the container from shock and subsequent dislodging of dried reagents located in said separate regions of said closed end of the container.
Claim 3
Dependent Claim
46 words
A container as defined in claim 1 wherein said wall means portion is shaped so that it has at least one flat surface to orient said container and said dividing means at said closed end to ensure that separate reagents are directed into said separate regions.
Claim 4
Dependent Claim
18 words
A container as defined in claim 2, wherein said flat surface extends generally parallel to said dividing means.
Claim 5
Dependent Claim
18 words
A container as defined in claim 2 wherein said flat surface extends generally perpendicular to said dividing means.
Claim 6
Dependent Claim
42 words
A container as defined in claim 1 wherein said portion of said container wall means adjacent said closed end and said dividing means is shaped in an arc, and said dividing means is generally parallel to the arc of said wall means.
Claim 7
Dependent Claim
32 words
A container as defined in claim 1 and further comprising means for anchoring deposits of reagents within said closed end of said container, and a deposit of reagents on said anchoring means.
Claim 8
Dependent Claim
41 words
A container as defined in claim 6 wherein said anchoring means comprise a raised rib over which said reagents are separately deposited, to anchor said reagents in place, said rib having a height less than the height of the separate deposits.
Claim 9
Dependent Claim
139 words
A container useful to extract antigens for an immunoassay comprising: A. wall means defining open and closed opposite ends, a portion of said wall means defining said closed end being flexible enough to permit squeezing; B. dividing means located in the closed end of the container for dividing the volume of said closed end into at least two separate regions; C. orienting means on the container for orienting said dividing means with respect to a reagent-depositing means so that separate reagents are deposited by said depositing means on opposite sides of, and spaced from, said dividing means, and further comprising D. means mounted on the closed end of the container extending from said closed end, for protecting the container from shock and subsequent dislodging of dried reagents located in said separate regions of said closed end of the container.
Claim 10
Dependent Claim
139 words

Claim 12
Dependent Claim
33 words
A container as defined in claim 8 wherein said orienting means comprise at least one flat surface on said wall means to orient said container and said dividing means in a container holder.
Claim 13
Dependent Claim
171 words
In a kit for extracting an antigen from body fluids, the kit including an extraction device in which two or more reagents are added, and a swab for insertion of body fluid specimen into a container and for mixing of the specimen and reagents, the improvement A. wall means defining open and closed opposite ends, a portion of said wall means defining said closed end being flexible enough to permit squeezing; B. dividing means located in the closed end of the container for dividing the volume of said closed end into at least two separate region; a portion of said wall means adjacent to said closed end being shaped and sized to cooperate with a depositing means to ensure deposit of reagents on either side of said dividing means, and further comprising C. means mounted on the closed end of the container extending from said closed end, for protecting the container from shock and subsequent dislodging of dried reagents located in said separate regions of said closed end of the container.
