Claims
- 1. A sanitary sampling system for attachment to a tube portion of a fluid containing enclosure comprising: a rigid stem portion for attachment to said tube portion of said fluid enclosure; a stopper portion having a lower portion for insertion into said rigid stem portion and said tube portion and having a flattened head portion of which a lower surface thereof abuts a flattened free extended edge of said rigid stem portion when a tail portion thereof is inserted into said rigid stem portion; a disk-shaped orifice plate fitting for placement on an upper surface of said flattened head portion of said stopper portion; an adjustable clamp for fitting snugly around said stem portion, said stopper portion and said orifice plate fitting; and an annular channel located in an upper surface of said flattened free extended edge of said rigid stem portion and in a lower flattened surface of said orifice plate fitting so as to allow both annular channels to be in direct contact with said stopper portion which allows said stopper portion to extend into said channels when said adjustable clamp is tightened to form an air-tight and leak-free seal.
- 2. A sanitary sampling system according to claim 1, wherein said stopper portion is constructed of a material selected from the group consisting of a resilient synthetic monomer, a resilient synthetic polymer and natural rubber.
- 3. A sanitary sampling system according to claim 1, wherein said stem portion, said orifice plate fitting and said adjustable clamp are constructed of a material independently selected from the group consisting of a rigid synthetic monomer, a rigid synthetic polymer, metal and wood.
- 4. A sanitary sampling system according to claim 1, wherein said stem portion, said stopper portion, said orifice plate fitting, and said adjustable clamp have a substantially cylindrical form when assembled.
- 5. A sanitary sampling system according to claim 1, wherein said stopper portion is designed to be puncturable by a needle to withdraw samples and to reseal upon withdrawal of said needle.
- 6. A method of assembling a sanitary sampling system onto a tube portion of a fluid containing enclosure comprising:
- a) positioning a stem portion of said sampling system over a free end of said tube portion of said fluid enclosure;
- b) inserting a stopper portion of said sampling system partially into said stem portion and said tube portion surrounded by said stem portion;
- c) placing an orifice plate fitting on a flattened exposed surface of said stopper portion;
- d) placing an adjustable ring clamp around said stem portion, stopper portion and orifice plate fitting; and
- e) tightening said adjustable ring clamp, whereby said stem portion, stopper portion and orifice plate fitting interlock to form an air-tight and leak-free seal wherein a first annular channel is formed in said stem portion and a second annular channel is formed in said orifice plate fitting, such that when said stem portion and said orifice plate fitting are assembled in direct contact extends therein upon tightening of said adjustable ring clamp in order to form an air-tight and leak-free seal.
- 7. A method of assembling a sanitary sampling system according to claim 6, wherein said stopper portion is constructed of a material selected from the group consisting of a resilient synthetic monomer, a resilient synthetic polymer and natural rubber.
- 8. A method of assembling a sanitary sampling system according to claim 6, wherein said stem portion, said orifice plate fitting and said adjustable ring clamp are constructed of a material independently selected from the group consisting of rigid synthetic monomers, rigid synthetic polymers, metal and wood.
- 9. A method of assembling a sanitary sampling system according to claim 7, wherein said stem portion, said stopper portion, said orifice plate fitting and said adjustable ring clamp have a substantially cylindrical form when assembled.
- 10. A method of assembling a sanitary sampling system according to claim 6, wherein said stopper portion is designed to be puncturable by a needle for the withdrawal of samples and to reseal upon withdrawal of said needle.
- 11. A sanitary sampling system for attachment to a fluid containing enclosure comprising:
- a rigid first portion for attachment to a tube portion of said fluid enclosure;
- a resilient second portion for partial insertion into said first portion and said tube portion; a rigid thin portion having an opening in the center thereof and designed for placement on an exposed flat surface of said resilient second portion;
- a rigid adjustable clamp for attachment around the periphery of said first, second and third portions and being tightenable to interlock said first, second, and third portions to form an air-tight and leak-free seal; and
- a first annular channel formed in said rigid first portion and a second annular channel formed in said rigid third portion, said first and second annular channels being in direct contact with said resilient second portion and allowing said resilient second portion to extend there into when said rigid adjustable clamp is tightened in order to form an air-tight and leak-free seal;
- whereby a needle portion of a syringe may be used to repeatedly puncture an exposed area of said resilient second portion to withdraw fluid samples from within said fluid containing enclosure.
- 12. A sanitary sampling system according to claim 11, wherein said resilient second portion is constructed from a material selected from the group consisting of synthetic monomers, synthetic polymers and natural rubber.
- 13. A sanitary sampling system according to claim 11, wherein said rigid first portion, rigid third portion, and rigid adjustable clamp are constructed from a material independently selected from the group consisting of synthetic monomers, synthetic polymers, metal and wood.
- 14. A sanitary sampling system according to claim 11, wherein said rigid first portion, said resilient second portion, said rigid third portion and said rigid adjustable clamp have a cylindrical form when assembled.
- 15. A sanitary sampling system according to claim 11, wherein said resilient second portion is designed to be repeatedly punctureable by said needle portion of said syringe and self-sealable upon withdrawal of said needle portion.
- 16. 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 containing tube portion of said fluid enclosure;
- b) inserting a resilient stopper member partially into said stem member and into said fluid 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 adjustable 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, wherein a first annular channel is formed in said stem member, a second annular channel is formed in said orifice plate member, said first and second annular 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.
- 17. A method according to claim 16, 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.
- 18. A method according to claim 16, 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.
- 19. A method according to claim 16, wherein said stem member, stopper member, orifice plate member and adjustable ring clamp have a substantially cylindrical form when assembled.
- 20. A method according to claim 16, wherein said stopper member is designed to be repeatedly puncturable by said needle and to self-seal upon withdrawal of said needle.
