Definitions

  • lid structure which is resealable to permit extended storage without evaporation and, simultaneously to accommodate mixing or sampling probes.
  • Lid structures which realize these goals are available in the art. Exemplary of such devices is that disclosed in United States Patent 3.994.594 (Sandrock et al.). However. such lid structures are believed incompatible for use in an environment in which the mixing and/or sampling probe is other than a sharp implement.
  • a lid structure which minimizes vapor transmission from compartment to compartment, thus minimizing contamination of the contents of one compartment by the contents of another compartment.
  • Active filter 97 is a dual-purpose second-order Q-controlled band pass filter.
  • the primary purpose of filter 97 is to prevent the power supply from driving the transducer system "out of band" into vibrational modes that have not been selected for use. Used in this way, it is called a mode suppressant filter.
  • the secondary purpose of filter 97 does not appear unless the feedback signal on line 101 is lost completely, such as at startup. In this event, starting circuit 98 which monitors the output signal from phase-shifter circuit 102, causes the Q of active filter circuit 97 to increase to the point where filter circuit 97 brakes into oscillation.
  • a second, upper, cover sheet 108 overlies the lower sheet 106.
  • the sheet 108 is joined to the sheet 106 along those interfacing portions thereof to thus define a substantially enclosed volume 110 within each receptacle 107.
  • the sheets 106 and 108 are joined by any suitable expedient and define a peripheral flange region 112 entirely surrounding the enclosed volume 110.
  • Disposed within each of the volumes 110 is a thermoplastic elastomer pad 112 such as that sold by West Company of Phoenixville. Pennsylvania, under formulation number 8553-3-5-1.
  • the pad 114 is received within each enclosed volume 110 and is sized such that a gap 116 is defined between the walls of the receptacle and the undersurface of the upper sheet 108.
  • the lid structure L in the above-described assembled relationship is arranged to overlie each container 10 in the strip 12.
  • the undersurface of the peripheral flange region 112 defined by the jointure of the sheets 106, 108 is heat sealed or otherwise attached to the sealing surface 22 of the compartments 12.
  • the containers are each closed by an impermeable seal which serves to form an evaporation barrier for the contents of the compartment and to isolate the containers against vapor cross contamination.
  • the sheet 108 is. in the preferred embodiment formed of a laminate of (i) an outer polyester film, such as that sold by E. I. du Pont de Nemours and Company under the trademark MYLAR, (ii) a polyvinylidene chloride coating such as that sold by Dow Chemicals Co. under the trademark SARAN. and (iii) an outer barrier sheet of polyethylene.
  • the polyethylene sheet interfaces against the lower sheet and is joined thereto.
  • any other suitable materials may be used for the sheets 106 and 108.
  • the top sheet 108 forms a vapor barrier to enhance the shelf life of a container covered by the lid L.
