Abstract
Abstract A needle cap and shield. An needle cap is provided with a continuous expandable shield. The shield is collapsible and thus it is capable of being easily packed and shipped. When released by the user, the shield expands into a fully protective needle shield which provides protection to the user from needle sticks. The shield does not have any voids or open areas, and is thus fully protective to the user. Also, in one embodiment, a flat edge segment is furnished; this flat edge enables the cap and shield, or a recapped syringe with cap and shield, to be securely positioned on a flat surface without danger of rolling away.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
97 words
A needle cap and shield, comprising: (a) a housing comprising (i) a sidewall, said sidewall having an interior and an exterior, and (ii) a frontal opening, said opening adapted to receive a needle; (b) a continuous flexible shield portion, said portion extending upward away from said exterior sidewall, said continuous shield portion further comprising a plurality of spaced panels extending upward from said exterior sidewall, wherein adjacent panels have interior edges therebetween, and wherein said interior edges are shaped for defining generally stiff projections to integrally support the said panels out of contact with said exterior sidewall.
Claim 2
Dependent Claim
97 words
A needle cap and shield, comprising: (a) a housing comprising (i) a sidewall, said sidewall having an interior and an exterior, and (ii) a frontal opening, said opening adapted to receive a needle; (b) a continuous flexible shield portion, said portion extending upward away from said exterior sidewall, said continuous shield portion further comprising a plurality of spaced panels extending upward from said exterior sidewall, wherein adjacent panels have interior edges therebetween, and wherein said interior edges are shaped for defining generally stiff projections to integrally support the said panels out of contact with said exterior sidewall.
Claim 3
Dependent Claim
30 words
The needle cap and shield as recited in claim 1, wherein said edges comprise ribs projecting from said exterior sidewall of said housing toward an outer edge of said panels.
Claim 4
Dependent Claim
33 words
The needle cap as recited in claim 2, wherein said ribs are fabricated of a material which allows said ribs to extend outward from a compressed, shipping position to an extended, protective position.
Claim 5
Dependent Claim
120 words
A needle cap and shield as set forth in claim 3, wherein the shield portion further comprises: a plurality of panels each having a central edge, said panels being affixed to said external surface portion of said cap along aid central edges; wherein said ribs extend outward from said cap portion upon release of said ribs from their compressed, shipping position, and wherein said panels are progressively more tautly pulled outward by said ribs as said ribs extend outwardly away from said cap portion, so that said panels form a protective barrier between a first, needle receiving end of said cap and a second, handling end of said cap, said handling end being adapted to be gripped by a user.
Claim 6
Dependent Claim
14 words
The needle cap as recited in claim 2, wherein said ribs are equally spaced.
Claim 7
Dependent Claim
23 words
The needle cap as recited in claim 2, wherein said ribs project the entire distance between said exterior sidewall and said outer edge.
Claim 8
Dependent Claim
85 words
The needle cap as recited in claim 2: (a) wherein said rib portions include central ends, said central ends being positioned within an optimum range position along said exterior sidewall, and (b) wherein said rib portions have a suitable length L, so that when said rib portions of length L are affixed to said housing at said optimum endpoint range position, said ribs do not impair the ability of a needle to engage said cap when said rib portions are in their compressed, shipping position.
Claim 9
Dependent Claim
28 words
The needle cap and shield as recited in claim 1, wherein said shield portion further includes a ring portion, said ring integrally formed with said external surface portion.
Claim 10
Dependent Claim
40 words
The needle cap with shield as recited in claim 8, wherein said shield portion is separable from said cap portion, and where said shield portion may be affixed to said cap portion at a desired position along said longitudinal axis.
Claim 11
Dependent Claim
116 words
A needle cap with shield as set forth in claim 1, wherein the shield portion further comprises a plurality of panels, each panel having a central edge, said panels being affixed along said central edges to said housing; wherein said integral supports extend outward from said housing upon release of said integral supports from their compressed, shipping position; and wherein said panels are progressively more tautly pulled outward by said integral supports as said integral supports extend outwardly away from said housing, so that said panels form a protective barrier between a first, needle receiving end of said cap and a second, handling end of said cap which is adapted to be gripped by a user.
Claim 12
Dependent Claim
117 words
A needle cap with shield as set forth in claim 8, wherein the shield portion further comprises a plurality of panels each having a central edge, said panels being affixed to said ring portion of said shield along said central edges; wherein said ribs extend outward from said ring portion upon release of said ribs from their compressed, shipping position, and wherein said panels are progressively more tautly pulled outward by said ribs as said ribs extend outwardly away from said cap portion, so that said panels form a protective barrier between a first, needle receiving end of said cap and a second, handling end of said cap which is adapted to be gripped by a user.
Claim 13
Dependent Claim
38 words
The needle cap of claims 10 or 11, wherein said panels each having an external edge, and wherein said external edge is flat, so that said cap does not tend to move when placed on a flat surface.
Claim 14
Dependent Claim
39 words
The needle cap of claim 2 wherein said integral supports, when said cap is in said expanded, protective position, provide a stable positioning means so that said cap does not tend to move when placed on a flat surface.
Claim 15
Dependent Claim
33 words
The needle cap of claim 1, wherein said continuous shield is shaped for integrally defining generally stiff projections of variable thickness for supporting the said shield out of contact with the exterior sidewall.
Claim 16
Dependent Claim
33 words
The needle cap as recited in claim 14, wherein said continuous shield has a tip and root, and wherein said shield has a thickness T which increases from the tip of the root.
Claim 17
Dependent Claim
18 words
The needle cap as recited in claim 1, wherein said shield includes a plurality of flat perimeter surfaces.
Claim 18
Dependent Claim
33 words
The needle cap as recited in claim 1, wherein said shield is fabricated of a material which allows said panel to extend outward from a compressed, shipping position to an extended, protective position.
Claim 19
Dependent Claim
32 words
The needle cap of claim 1, wherein said shield has an external edge, and wherein said external edge is rounded, so that said cap may move when placed on a flat surface.
Claim 20
Dependent Claim
26 words
The needle cap and shield as recited in claim 2, wherein a tab portion is provided to secure said shield portion in said compressed, shipping position.
Claim 21
Dependent Claim
22 words
The needle cap and shield as set forth in claim 19, wherein said tab is provided in a bright or fluorescent color.
