Claim 2

A container comprising first and second air-impermeable retaining plates each having two main faces and arranged with one main face of the first plate confronting one main face of the second plate, at least one recess in said one main face of said first plate, and a resilient, air-impermeable sealing member positioned between the retaining plates continuously about the recess, the two retaining plates being fitted in a frame defining a channel-section recess which extends about the periphery of the retaining plates and in which edge portions of the retaining plates are received to compress the retaining plates against the sealing member thereby to form air-tight seals between the sealing member and the retaining plates respectively, the frame including at least two frame members both of which are readily removable to permit disassembly of the container and are readily replaceable to facilitate reassembly of the container.

Claim 3

A container as described in claim 1 in which said one main face of one of the plates contains a groove into which the sealing member is fit.

Claim 4

A container as described in claim 1, wherein one of said frame members is formed with a groove at a free end thereof and another of said frame members is also formed with a groove at a free end thereof, said grooves being in alignment and communication with one another, and wherein the container also comprises an elongated identifying piece having one end fitted in one of said grooves and its opposite end fitted in the other groove.

Claim 5

A container as described in claim 1, wherein one of said frame members has a region of reduced cross-section at a free end thereof and another of said frame members also has a region of reduced cross-section at a free end thereof, said free ends being in alignment with one another so that the regions of reduced cross section together form a groove extending transversely with respect to the frame members and across the juncture therebetween, and wherein the container also comprises a channel section identifying piece fitted in the groove and concealing said juncture.

Claim 6

A container comprising a holding plate having one or more holes therethrough, a continuous resilient air-impermeable sealing member positioned about the periphery of the holding plate, and first and second air-impermeable retaining plates, at least one of which is transparent, in contact with the sealing member on either side of the holding plate, the two retaining plates being fitted in a frame defining a channel-section recess which extends about the periphery of the retaining plates and in which edge portions of the retaining plates are received to compress the retaining plates against the sealing member thereby to form air-tight seals between the sealing member and the retaining plates respectively, the frame including at least two frame members both of which are readily movable to permit disassembly of the container and are readily replaceable to facilitate reassembly of the container, and the container also comprising a transparent lifter member of uniform thickness less than the thickness of the holding plate, the lifter member being adapted to fit into one of the holes in the holding plate and being of substantially the same cross-sectional form as said one hole.

Claim 7

A container comprising a holding plate having one or more holes therethrough, a continuous resilient air-impermeable sealing member positioned about the periphery of the holding plate, and first and second air-impermeable retaining plates, at least one of which is transparent, in contact with the sealing member on either side of the holding plate, the two retaining plates being fitted in a frame defining a channel-section recess which extends about the periphery of the retaining plates and in which edge portions of the retaining plates are received to compress the retaining plates against the sealing member thereby to form air-tight seals between the sealing member and the retaining plates respectively, the frame including at least two frame members both of which are readily movable to permit disassembly of the container and are readily replaceable to facilitate reassembly of the container, and the container also comprising a transparent lifter member of uniform thickness less than the thickness of the holding plate, the lifter member being adapted to fit into one of the holes in the holding plate and being of substantially the same cross-sectional form as said one hole.
