Abstract
Abstract An apparatus for storing and dispensing a plurality of disparate, reactible fluid materials in a relatively viscous state in separate storage locations including means for dispensing the fluid through separate, easily removable needles. A plurality of closely adjacent cylinders have distinct and separate interiors with nozzles formed at one end. Separate removable needles have sealed locking arrangements for attachment to the nozzles. Different designs and structures of the needles are given so that the fluids can be mixed together, joined together or kept separate until injected through needle point openings. Structure is provided for disproportionately mixing the separately contained materials according to the desired mix. Preferably, the dispensing cylinders are formed of transparent material having graduated measuring marks on the liquid-containing portions. The entire apparatus may be constructed of inexpensive materials, such as plastic, the apparatus being intended for disposal after the fluid liquids prepackaged therein have been dispensed.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
109 words
Apparatus for storing and dispensing a plurality of disparate inter-reactable fluids from separate storage locations, comprising: a plurality of distinct, elongate chambers containing fluids, each chamber including a piston for forceably ejecting the fluid therefrom through a tapered nozzle; needle means having a corresponding plurality of interior conduits for dispensing fluid from said nozzles; lock means including a ridge projecting about an exterior surface of each tapered nozzle; and releasable retaining means comprising a separable needle block having a fluid conduit with an interior groove for engaging a corresponding nozzle ridge and means for retaining associated needle means in sealing relationship with the chamber nozzles and the fluid conduits.
Claim 2
Dependent Claim
109 words
Apparatus for storing and dispensing a plurality of disparate inter-reactable fluids from separate storage locations, comprising: a plurality of distinct, elongate chambers containing fluids, each chamber including a piston for forceably ejecting the fluid therefrom through a tapered nozzle; needle means having a corresponding plurality of interior conduits for dispensing fluid from said nozzles; lock means including a ridge projecting about an exterior surface of each tapered nozzle; and releasable retaining means comprising a separable needle block having a fluid conduit with an interior groove for engaging a corresponding nozzle ridge and means for retaining associated needle means in sealing relationship with the chamber nozzles and the fluid conduits.
Claim 3
Dependent Claim
70 words
The apparatus of claim 1 wherein each tapered nozzle has a center line offset from a center line of its corresponding elongate chamber, each tapered nozzle abutting the tapered nozzle of every other chamber and having an opening adjacent every other tapered nozzle opening, the combination of tapered nozzles defining a common exterior surface thereon; and wherein further the lock means includes an annular ridge formed around the common surface.
Claim 4
Dependent Claim
20 words
The apparatus of claim 2 wherein the needle block interior groove is formed to sealingly fit over the annular ridge.
Claim 5
Dependent Claim
28 words
The apparatus of claim 1 wherein the needle means has a separate opening for each needle interior conduit, all such openings being positioned close together as a point.
Claim 6
Dependent Claim
30 words
The apparatus of claim 1 wherein the needle means has a single opening at a point, the interior conduits merging into a single conduit directing fluid into the single opening.
Claim 7
Dependent Claim
34 words
The apparatus of claim 5 wherein the interior conduits merge into the single conduit in an expanded chamber having a substantially increased cross-sectional area relative to the combined cross-sectional areas of the interior conduits.
Claim 8
Dependent Claim
39 words
The apparatus of claim 1 wherein the nozzle openings are disproportionate in cross-sectional area to each other in proportion to the ratio of the fluid material from each nozzle opening's corresponding tubular chamber to a predetermined disparate fluid combination.
Claim 9
Dependent Claim
28 words
The apparatus of claim 1 wherein each piston may be operated selectively and individually relative to the other pistons, and selectively uniformly in movement with the other pistons.
Claim 10
Dependent Claim
45 words
The apparatus of claim 1 wherein the cross-sectional area of each chamber and of its piston is proportional to the cross-sectional area of the other chambers in the ratio of the fluid volume in that chamber to the corresponding fluid volumes in the other chambers.
Claim 11
Dependent Claim
27 words
The apparatus of claim 9 wherein the needle means has a separate opening for each needle conduit, with such openings being positioned close together at a point.
Claim 12
Dependent Claim
31 words
The apparatus of claim 9 wherein the needle means has an additional opening at a point, the interior conduits merging into a single conduit directing fluid into said single additional opening.
Claim 13
Dependent Claim
34 words
The apparatus of claim 11 wherein the interior conduits merge into the single conduit in an expanded chamber having a substantially increased cross-sectional area relative to the combined cross-sectional areas of the interior conduits.
Claim 14
Dependent Claim
39 words
The apparatus of claim 1 wherein the needle block has an interior configuration adapted to position the needle means in place aligned with said nozzles when the needle block is mounted with its interior groove engaging said projecting ridge.
Claim 15
Dependent Claim
35 words
The apparatus of claim 13 wherein the interior configuration is further adapted to permit the release and replacement of said needle means from the needle block when the needle block is separated from said nozzles.
Claim 16
Dependent Claim
52 words
The apparatus of claim 1 wherein the needle means include a tapered exterior surface, and wherein the needle retaining means include a needle opening having a tapered interior surface for mating with the needle means exterior surface and adapted to releasably retain the needle means in sealing relationship in the needle block.
Claim 17
Dependent Claim
60 words
The apparatus of claim 15 wherein the needle means further include an outwardly projecting shoulder extending about the portion of the needle means adjacent the nozzles, and wherein the needle retaining means further include an interior recess located between said groove and said opening for receiving said shoulder and retaining the needle means in sealing relationship within the needle block.
Claim 18
Dependent Claim
33 words
The apparatus of claim 1 wherein one of the projecting ridge and the material of the needle block defining said interior groove is resilient to permit releasably fitting the groove over the ridge.
Claim 19
Dependent Claim
43 words
The apparatus of claim 17 wherein the needle block is of resilient material to permit the groove to fit tightly over the ridge and to establish a sealing relationship between the needle block fluid conduit and the nozzles and the needle means, respectively.
