Abstract
Abstract The invention relates to a filled, thermoplastic unit dose injection solution container the outlet opening of which is sealed. The outlet opening is designed to fulfill the specifications for a standardized female cone intended to be non-leakingly connected to a correspondingly standardized male cone of a syringe in order to transfer the injection solution directly into the syringe. The unit dose container is preferably non-resealably sealed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
256 words
A filled thermoplastic solution container containing a single dose of a sterile medication for administration to a human or animal patient by injection using a hypodermic syringe comprising a syringe having a conical tip to which a hypodermic needle is attached, said container having a neck portion with an inner surface which has converging and diverging sections which intersect and define an orifice at their intersection, the diverging section extending outwardly from said orifice to a sealing zone which is larger in diameter than said orifice, and a non-reusable tear seal which extends over and is sealed to said sealing zone at a tear line, which tear seal thereby protects the inner surfaces of said converging and diverging sections and the contents of said container from contamination, the inner surface of said diverging section being shaped in the vicinity of said orifice for removably and tightly receiving the conical tip of said syringe to thereby form a substantially leak-proof seal between said diverging section and syringe tip when said syringe tip is inserted for filling said syringe, whereby said tear seal can be removed by tearing it away, while the portion of the divergent section in the region of the orifice intended to receive said conical tip maintains its shape whereby the conical tip of said syringe can be inserted thereto in a leak-proof connection between said container and said syringe through which connection the single dose of medication can be transferred directly from the container to the syringe and the container can be thereafter discarded.
Claim 2
Dependent Claim
256 words
A filled thermoplastic solution container containing a single dose of a sterile medication for administration to a human or animal patient by injection using a hypodermic syringe comprising a syringe having a conical tip to which a hypodermic needle is attached, said container having a neck portion with an inner surface which has converging and diverging sections which intersect and define an orifice at their intersection, the diverging section extending outwardly from said orifice to a sealing zone which is larger in diameter than said orifice, and a non-reusable tear seal which extends over and is sealed to said sealing zone at a tear line, which tear seal thereby protects the inner surfaces of said converging and diverging sections and the contents of said container from contamination, the inner surface of said diverging section being shaped in the vicinity of said orifice for removably and tightly receiving the conical tip of said syringe to thereby form a substantially leak-proof seal between said diverging section and syringe tip when said syringe tip is inserted for filling said syringe, whereby said tear seal can be removed by tearing it away, while the portion of the divergent section in the region of the orifice intended to receive said conical tip maintains its shape whereby the conical tip of said syringe can be inserted thereto in a leak-proof connection between said container and said syringe through which connection the single dose of medication can be transferred directly from the container to the syringe and the container can be thereafter discarded.
Claim 3
Dependent Claim
20 words
The container according to claim 1, wherein the outlet opening has a maximum opening diameter smaller than about 1.0 cm.
Claim 4
Dependent Claim
16 words
The container according to claim 1, wherein the outlet opening is sealed by a non-resealable cap.
Claim 5
Dependent Claim
23 words
The container according to claim 3, wherein the cap comprises a transversal projection providing an increased moment for use in breaking the seal.
Claim 6
Dependent Claim
22 words
The container according to claim 4, wherein the container comprises a projection providing an increased moment for use in breaking the seal.
Claim 7
Dependent Claim
24 words
The container according to claim 1, wherein the container is enclosed in a moisture impermeable bag made of a laminate of metal and plastic.
Claim 8
Dependent Claim
35 words
A container according to claim 1 characterized in that the wall of the container is sufficiently thin and flexible that the container collapses to permit the injection solution to be drawn out by a syringe.
Claim 9
Dependent Claim
36 words
The container according to claim 1, wherein the inner surface of the outlet opening of the container has a shape to form a substantially leak proof seal with a standard Luer male cone of a syringe.
Claim 10
Dependent Claim
36 words
The container according to claim 1, wherein the container has a base opposite the outlet opening for supporting and holding the container in an upright position with the outlet opening upwards when the container is filled.
Claim 11
Dependent Claim
47 words
The container according to claim 1, wherein a wall with a capillary constriction is provided inside the container below the outlet opening, to prevent solution from flowing out of the container when the container is positioned having its opening below the level of solution in the container.
