Abstract
A sanitary sampling system (10) for attachment to a tube (12) portion of a fluid containing enclosure. The sanitary sampling system is comprised of a rigid stem portion (14) for attachement to the tube portion (12) of the fluid enclosure, a stopper portion (16) having a lower portion for insertion into the rigid stem portion (14) and tube portion (12), a disk-shaped orifice plate fitting (18) for placement on the upper surface of the stopper portion (16) and an adjustable clamp (20) for adjustment around the stem portion (14), orifice plate fitting (18) and stopper portions (16) of the sanitary sampling system. The sanitary sampling system is designed to enable the stem portion (14) stopper portion (16) and orifice plate fitting (18) to interlock to form an air-tight and leak-free seal when the adjustable clamp (20) is tightened.

have a tube 12 which is connected and in fluid communica-tion with a fluid enclosure (not pirtured). The free end 13 of tu~e 12 is of a standardized size which enables stem portion 14 to be slipped thereon and may be held in position by friction fit or by an adhesive.
Stem portion 14 is substantially tubular in shape having an outwardly extending area 69 which ultimately forms an upper ridge 70 having a larger diameter than that of the lower portion 71 just ~elow extending area 69. As illustrated in Figure 6, the upper surface 72 of stem portion 14 has a channel i3 which extends there around an equidistance fro~ opening 7~. The interior edge 74 of upper surface 72 extends inwardly whereby opening 77 has a smaller diameter than that of the ste~ interior surface 76.
This ~orms a seat member 75 as shown in Figure 7 which when stem portion 14 is attached to tube 12 causes free end 13 of tube 12 to abut seat membsr 75 to ensure a tight seal.
Stopper portion 16 is designed to fit securely within st~ portion 14 and tubQ 12. The stopper portion 16 has a lower tail portion 19 whic.h is cylindrical in shape and has a disX-shaped head portion 21 integrally formed therewith.

Holding stem portion 14, stopper portion 16 and orifice plate fitting 18 in tight sealed communication is clamp 20 shown in detail in Figure 4. Clamp 20 is a 360-clamp having two portions, a major arm portion 22 and a minor arm portion 24. Major arm portion 22 has a rod means 60 fixed by mean~ of a pin 30 between an extended upper extension mean. 32 and an extended lower extens~on means 34. The frae end 78 of rod means 60 has threaded engage~ent means 28 and a wing nut handle 26 which engages therewith. Major arm portion ~2 likewise has an extended upper extension means 40 and an extended lower extension means 42 opposite extension means 32 and 34. Major arm portion 22 has an 180 curve as doe~ minor arm portion 24.
Minor ar~ portion 24 additionally has a mid extender 46 which f its betwaen upper exten~ion ~eans 40 and lower extension means 42 of major arm ~rtion 22 which serves a~
a hinge when pi~ned there between by pin member 44 Opposite mid extender 46 of minor arm portion 24 is upper extension 56 and lower extension 58. Rod member 60 ~ay b~

Once clamp 20 is securely tightened around the other three portions of the device head portion 21 of stopper 16 is compressed between stem portion 14 and orifice plate fitting 18. ~owever; stopper portion 16 is constructed of a resilient mat~rial such that in ths area of channel 73 and channel 62, head portion 21 is not compressed and thereby extends into channel 73 and channel 62 to interlock therewith as illustrated in Figure ?. A
strong air-tight seal is created by this interlockinq O action preventing any fluid communcation between the inside and outside of pipe 12. This prevents contaminants from enterinq the ~luid within tube 12 as well as preventing any leakage.
.
Once a~sembled, sanitary samples may then be 3 collected ~y piercing a needl~ portion 80 of a syringe 82 through upper opening 84 in clamp 20, through opening 66 in orifice plate fitting 18 and pieroing through stopper 16 so as to be in direct communication with th~ fluid in the interior o~ pipe 12. A sample may then be extracted from pip~ 12 by pulling plun~er 86 outwardly from within the syringe housing 88 and then removing the needle portion 80 from within the stopper 16 as well as the samplinq system.
This proces~ may be repeated nu~erou~ times without leakage or contamination o~ the sample.

19) A method of taking sanitary fluid samples from a fluid containing enclosure comprising:
a) positioning a rigid tubular stem member having an outwardly extending flange area onto a free end of a fluid con-taining tube portion of said fluid enclosure;
b) inserting a resilient stopper member partially into said stem member and into said fluid containing tube allowing an extended flattened portion of said stopper member to abut said outwardly extending flange area;
c) placing a rigid orifice plate member on said extended flattened portion of said stopper member opposite said outwardly extending flange area so as to position an opening in said orifice plate member over the middle of said extended flattened portion;
d) placing an ajustable ring clamp around said stem member, stopper member and orifice plate member;
e) tightening said adjustable ring clamp so as to cause said stem member, stopper member and orifice plate member to interlock and form an air-tight and leak-free seal;
f) puncturing said stopper member with a needle portion of a syringe and withdrawing a sample of fluid from said fluid containing tube; and g) withdrawing said needle portion from said stopper member.

f) puncturing said stopper member with a needle portion of a syringe and withdrawing a sample of fluid from said fluid containing tube; and g) withdrawing said needle portion from said stopper member.
20) A method according to claim 19, wherein said stopper member is constructed of a material selected from the group consisting of a resilient synthetic monomer, a resilient synthetic polymer and natural rubber.
21) A method according to claim 19, wherein said stem member, orifice plate member and adjustable ring clamp are constructed from a material independently selected from the group consisting of a rigid synthetic monomer, a rigid synthetic polymer, metal and wood.
22) A method according to claim 19, wherein a first channel is formed in said stem member a second channel is formed in said orifice plate member, said first and second channels being in direct contact with said stopper member and allowing said stopper member to extend there into when said rigid adjustable clamp is tightened in order to form an air-tight and leak-free seal.
23) A method according to claim 19, wherein said stem member, stopper member, orifice plate member and adjustable ring clamp have a substantially cylindrical form when assembled.
24) A method according to claim 19, wherein said stopper member is designed to be repeatedly puncturable by said needle and to self-seal upon withdrawal of said needle.
