BFS injection and connection assemblies

1 . A Blow-Fill-Seal (BFS) injection system comprising:

a) a BFS bottle, comprising:

i) a radially compressible fluid reservoir storing a fluid content;

ii) a first neck portion in fluid communication with the radially compressible fluid reservoir and formed at a first end of the BFS bottle;

iii) a second neck portion in fluid communication with the radially compressible fluid reservoir and formed at a second end of the BFS bottle;

iv) an angled exterior flange formed on an exterior of the first neck portion;

v) a first fluid seal formed at the first end of the BFS bottle, the first fluid seal comprising a grip portion and defining a tear line between the grip portion and the first neck portion such that a shear force developed between the grip portion and the first neck portion causes the grip portion to separate from the BFS bottle and causes the first fluid seal to tear at the tear line, exposing the fluid content of the radially compressible reservoir at the first end of the BFS bottle;

vi) a mounting feature formed proximate to the second end; and

vii) a second fluid seal formed at the second end, the second fluid seal defining a radially planar piercing surface.

2 . The BFS injection system of claim 1 , further comprising:

b) a needle hub defining a first hub end and a second hub end, the first hub end defining a mounting socket comprising interior threads into which, in the case that the first fluid seal is separated from the BFS bottle at the tear line, the angled exterior flange is axially and rotationally mated, and the second hub end being coupled to a needle such that an application of radially inward force to the radially compressible fluid reservoir expels a dose of fluid stored in the radially compressible fluid reservoir through the needle.

3 . The BFS injection system of claim 2 , wherein the angled exterior flange comprises two angled exterior flanges disposed on opposite sides of the first neck portion and wherein each of the two angled exterior flanges extends between one quarter and one third along an outer circumference of the first neck portion.

4 . The BFS injection system of claim 2 , wherein the first neck portion defines a first exterior diameter at the angled exterior flange and defines a second exterior diameter between the angled exterior flange and the radially compressible fluid reservoir, and wherein the second exterior diameter is less than the first exterior diameter.

5 . The BFS injection system of claim 4 , wherein the first neck portion comprises, at the second exterior diameter, an axial rib connecting the radially compressible fluid reservoir to the first neck portion, and wherein the axial rib extends radially outward from the second exterior diameter to the first exterior diameter.

6 . The BFS injection system of claim 1 , further comprising:

b) a BFS connection assembly comprising:

i) a BFS port formed at a first assembly end, the BFS port comprising a seat configured to accept the mounting feature of the BFS bottle in the case that the second end of the BFS bottle is inserted into the BFS port;

ii) an outlet port formed at a second assembly end, the outlet port comprising threads;

iii) a projection extending axially from a first projection end at an interior extent of the outlet port, the projection defining a fluid outlet at a second projection end thereof; and

iv) a tubular piercing element coupled within the projection and connecting the fluid outlet to the BFS port, wherein the tubular piercing element is disposed to pierce the second fluid seal of the BFS bottle in the case that the second end of the BFS bottle is inserted into the BFS port.

7 . The BFS injection system of claim 6 , wherein the projection comprises a cone.

8 . The BFS injection system of claim 7 , wherein the cone is tapered from the first projection end to the second projection end.

9 . The BFS injection system of claim 6 , wherein the threads of the outlet port comprise interior threads formed within the outlet port.

10 . The BFS injection system of claim 6 , wherein the threads of the outlet port comprise exterior threads formed on an outside surface of the outlet port.

11 . The BFS injection system of claim 6 , wherein the tubular piercing element comprises a metal tube disposed in an interior channel of the projection and a proximate end of the metal tube is beveled to form a point that extends axially into the BFS port.

12 . The BFS injection system of claim 6 , wherein the seat comprises an axial track and wherein the mounting feature of the BFS bottle comprises an axial exterior flange.
