Abstract
Abstract An adapter unit suitable for fitting upon the wall which forms the top portion of the neck of a container or bottle, and the combination of such unit with a septum inlet device or valve. The adapter unit comprises an internally threaded tubular member, with a flanged end containing a peripherally located O-ring, which flanged end of the said tubular member rests atop the neck of a bottle and can be retained in such position by use of a metal sealing ring. In one embodiment, a septum inlet device is provided by location of a septum within the said tubular member, and it can be retained therein by a second tubular member, externally threaded for engagement with the said adapter tubular member. In another embodiment, a valve assembly is located within the adapter unit.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
178 words
An adapter unit suitable for fitting upon the wall which forms the top portion of the neck of a bottle comprising, in combination, a tubular member formed by an enclosing wall providing an axial opening therethrough, the inside wall of which is threaded and the upper portion thereof is flanged outwardly and provided with a circumferential notch, the flanged portion thereof being adapted for resting upon the top of the bottle neck while the smaller diameter portion of the said tubular member can be thrust into the neck of the bottle, an O-ring for fitting within the circumferential notch of the flanged portion of said tubular member, a sealing ring with top and side walls, a central opening through the top wall of which coincides with the axial opening through the said tubular member, the lower portion of the side wall of which can be secured to the bottle neck, whereby the O-ring is bulged outwardly and thrust against the inside surface of the sealing ring to form an effective leakproof seal upon the top of the bottle.
Claim 2
Dependent Claim
178 words
An adapter unit suitable for fitting upon the wall which forms the top portion of the neck of a bottle comprising, in combination, a tubular member formed by an enclosing wall providing an axial opening therethrough, the inside wall of which is threaded and the upper portion thereof is flanged outwardly and provided with a circumferential notch, the flanged portion thereof being adapted for resting upon the top of the bottle neck while the smaller diameter portion of the said tubular member can be thrust into the neck of the bottle, an O-ring for fitting within the circumferential notch of the flanged portion of said tubular member, a sealing ring with top and side walls, a central opening through the top wall of which coincides with the axial opening through the said tubular member, the lower portion of the side wall of which can be secured to the bottle neck, whereby the O-ring is bulged outwardly and thrust against the inside surface of the sealing ring to form an effective leakproof seal upon the top of the bottle.
Claim 3
Dependent Claim
164 words
The apparatus of claim 1 wherein a valve is included with the combination, said valve comprising a tubular member formed by an enclosing wall providing an axial opening therethrough, said wall being externally threaded and adapted for threadable engagement with the threaded inside wall of the tubular member of the adapter unit, and wherein is provided a pair of lateral openings which intersect with the said axial opening, a septum located within a first lateral opening, which lies across, covers and seals the axial opening through the said tubular member, a stem movably mounted within the second lateral opening in the wall of said tubular member, which stem can be moved to align the lateral opening of the stem and axial tubular opening to open the valve and thereby expose the septum to penetration as by the cannula of a needle syringe used to withdraw fluid from the bottle, or closed to such exposure for maximum confinement of the fluid contents of the bottle.
Claim 4
Dependent Claim
21 words
The apparatus of claim 2 wherein the movable stem used for opening and closing the valve is of a push-pull type.
Claim 5
Dependent Claim
23 words
The apparatus of claim 2 wherein the movable stem is rotatable within the lateral opening such as to open and close the valve.
Claim 6
Dependent Claim
21 words
The apparatus of claim 2 wherein the tubular members of both the adapter unit and valve are constituted essentially of Teflon.
Claim 7
Dependent Claim
122 words
The apparatus of claim 2 wherein the septum located within the tubular member constituting a portion of the valve is located above the movable stem and in series therewith, the lowermost portion of the wall of the said valve tubular member is externally threaded and provided with a projecting nib, and the inside wall of the tubular member constituting a portion of the adapter unit is provided with an opening of diameter corresponding to the external diameter of the threaded valve tubular member and threaded for receipt and threadable engagement with the said valve member, and a smaller diameter opening contiguous to the larger diameter opening of said adapter unit within which the nib of the said valve tubular member is received.
Claim 8
Dependent Claim
59 words
The apparatus of claim 1 wherein the axial opening within the tubular member of the adapter unit is constituted of a contiguous pair of openings, an upper larger diameter opening the wall of which is internally threaded, and a lower smaller diameter opening communicated with the said larger diameter opening, said pair of openings forming an annular surface therebetween.
Claim 9
Dependent Claim
47 words
The apparatus of claim 7 wherein a disc-shaped septum is located upon the annular surface between the pair of openings, and a tubular member with an externally threaded wall is threadably engaged with the threaded upper larger diameter opening of the tubular member forming the adapter unit.
Claim 10
Dependent Claim
19 words
The apparatus of claim 8 wherein the said tubular member engaged with the adapter unit is comprised of Teflon.
Claim 11
Dependent Claim
26 words
The apparatus of claim 9 wherein the tubular member adjoined with the adapter unit is provided with a plurality of vertically oriented parallelly aligned axial openings.
