Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
220 words
An enclosure for an article comprising: a permanently formed ground secured rigid base formed in a manner as to discourage water vapour transmission; a peripheral recess extending around a portion of said base; a strip of flexible sheet plastics material of low water vapour transmissibility having one longitudinal edge portion sealing secured to the base; one half of a sliding clasp fastener extending along the other longitudinal edge portion of the strip; a cover of open bag-like form formed of flexible sheet plastics material of low water vapour transmissibility having a mouth; a second half of said sliding clasp fastener extending about the edge portion of the cover constituting said mouth and sealingly, but releasably, connected to the fastener half on said strip; said base recess being dimensioned to house the portion of said strip adjacent said peripheral recess when such strip is disconnected from said cover to provide protection for that portion of the strip when the article is placed on, or removed from, the base; the arrangement being such that when the sliding clasp fastener halves are interconnected a substantially hermetically sealed enclosure is provided and an environment may be maintained within the enclosure having a lower relative humidity than the ambient air outside the enclosure and yet permits for ready removal of the article from the enclosure.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
15 words
An enclosure according to claim 1, wherein humidity sensing means are provided within the enclosure.
Claim 4
Dependent Claim
23 words
An enclosure according to claim 2, wherein said sensing means are connected to an electrical lead extending from the exterior of the enclosure.
Claim 5
Dependent Claim
133 words
An air-supported or inflated enclosure comprising: a rigid base; a peripheral recess extending around the base; a strip of flexible substantially water and air impermeable plastics material having one longitudinal edge portion secured to the base; a cover of open bag-like form formed of a substantially water and air impermeable flexible plastics sheet material having a mouth; complementary halves of a sliding clasp fastener being secured respectively to a second longitudinal edge of the strip and about the edge portion of the mouth of the cover to permit the strip and the cover to be sealingly but releasably interconnected to form an enclosure; an inlet and an outlet in said enclosure, each of generally frusto-conical form and being formed of a flexible material; and means connected to said inlet for inflating saiD enclosure.
Claim 6
Dependent Claim
133 words
An air-supported or inflated enclosure comprising: a rigid base; a peripheral recess extending around the base; a strip of flexible substantially water and air impermeable plastics material having one longitudinal edge portion secured to the base; a cover of open bag-like form formed of a substantially water and air impermeable flexible plastics sheet material having a mouth; complementary halves of a sliding clasp fastener being secured respectively to a second longitudinal edge of the strip and about the edge portion of the mouth of the cover to permit the strip and the cover to be sealingly but releasably interconnected to form an enclosure; an inlet and an outlet in said enclosure, each of generally frusto-conical form and being formed of a flexible material; and means connected to said inlet for inflating saiD enclosure.
Claim 7
Dependent Claim
37 words
An enclosure according to claim 4, wherein said flexible conical outlet changes configuration to discourage egress of air therethrough when the pressure differential between the interior and the exterior of the enclosure drops below a predetermined value.
Claim 8
Dependent Claim
35 words
An enclosure according to claim 5, wherein a substantially rigid collar extends about said inlet and said outlet and closure caps are provided to permit sealing of the enclosure by engagement thereof with said collars.
