Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
230 words
A dispenser system for administering fluid to a confined location, such as the eye, comprising a spray nozzle having a head with an orifice, the head having at least one first aligning means thereon, an eye shield having an opening at one end thereof and a sleeve at the other, said sleeve being a closed surface except for a keyway therein which is formed with a shape substantially complementary to that of the head and at least one second aligning means substantially transverse to the longitudinal axis of the shield to mate with the first aligning means on the head, said first and second aligning means positioned to align the orifice toward the shield opening when the keyway of the sleeve is placed over the nozzle head with said first and second aligning means in a mating relationship when the shield is in a position of use to dispense fluid, the sleeve also having formed thereon at least one third aligning means substantially parallel to the longitudinal axis of the shield to mate with the first aligning means on the head, said first and third aligning means positioned to align the shield in a storage position with a closed portion of the sleeve remote from the keyway covering the orifice of the head when the nozzle head is inserted into the shield through its said opening at one end thereof.
Claim 2
Dependent Claim
230 words
A dispenser system for administering fluid to a confined location, such as the eye, comprising a spray nozzle having a head with an orifice, the head having at least one first aligning means thereon, an eye shield having an opening at one end thereof and a sleeve at the other, said sleeve being a closed surface except for a keyway therein which is formed with a shape substantially complementary to that of the head and at least one second aligning means substantially transverse to the longitudinal axis of the shield to mate with the first aligning means on the head, said first and second aligning means positioned to align the orifice toward the shield opening when the keyway of the sleeve is placed over the nozzle head with said first and second aligning means in a mating relationship when the shield is in a position of use to dispense fluid, the sleeve also having formed thereon at least one third aligning means substantially parallel to the longitudinal axis of the shield to mate with the first aligning means on the head, said first and third aligning means positioned to align the shield in a storage position with a closed portion of the sleeve remote from the keyway covering the orifice of the head when the nozzle head is inserted into the shield through its said opening at one end thereof.
Claim 3
Dependent Claim
29 words
A dispenser system as in claim 1 wherein said first aligning means is a rib and is formed on said nozzle head at a position spaced from the orifice.
Claim 4
Dependent Claim
50 words
A dispenser system as in claim 2 wherein said first aligning means is located on said head at a position opposite to the orifice, said sleeve having a curved bottom wall on which the keyway is formed and a back wall, said second aligning means formed on said back wall.
Claim 5
Dependent Claim
53 words
A dispenser system as in claim 3 wherein the front portion of the keyway remote from the back wall is curved to conform to the shape of the nozzle head when the sleeve is on said head in a position of use to surround the lower portion of the head adjacent the orifice.
Claim 6
Dependent Claim
27 words
A dispenser system as in claim 1 wherein said first aligning means comprises at least one rib and said third aligning means comprises at least one groove.
Claim 7
Dependent Claim
55 words
A dispenser system as in claim 5 wherein said shield is of translucent material and said at least one groove comprising said third aligning means is of reduced thickness with respect to the area of the shield on which it is located to aid in the admission of light into the interior of the shield.
Claim 8
Dependent Claim
31 words
A dispenser system as in claim 1 wherein there are a plurality of first aligning means on the nozzle head, and a corresponding number of second aligning means on said shield.
Claim 9
Dependent Claim
88 words
A dispenser system as in claim 1 wherein said shield is of translucent material and said sleeve of said shield has a substantially flat top wall opposite the portion on which the keyway is formed, and at least one groove formed on the interior of the sleeve adjacent the top wall to reduce the thickness of the shield material to admit additional light into the shield in the area of the orifice when said shield is in a position of use mounted by said keyway on the nozzle.
Claim 10
Dependent Claim
27 words
A dispenser system as in claim 1 wherein the portion of the head surrounding the orifice is of a different color from the remainder of the head.
Claim 11
Dependent Claim
71 words
A dispenser system as in claim 1 wherein the lower portion of the head is hollow and has an amount of resiliency thereto, the second aligning means being sized with respect to the first aligning means on the head, a portion of which is located on the resilient part of the head, to produce a friction fit when the sleeve is both in the use postion and in the storage position.
Claim 12
Dependent Claim
14 words
A dispenser system as in claim 1 wherein said shield is of translucent material.
