System of claim 2, wherein the base structure comprises a holder having an opening; a storage container having an opening, containing the plurality of test elements, and received at least partially within the holder; and the flap seals one of the openings.
Claim 8
Dependent Claim 13 words
System of claim 5, wherein the storage container is removable from the holder.
Claim 9
Dependent Claim 20 words
System of claim 6, wherein the storage container can be inserted into the holder from a side opposite the flap.
Claim 10
Dependent Claim 13 words
System of claim 2, wherein a desiccant is present inside the base structure.
Claim 11
Dependent Claim 22 words
System of claim 2, wherein the base structure has a slide which is operably connected to the flap to open the flap.
Claim 12
Dependent Claim 17 words
System of claim 2, wherein a sealing element is located between the flap and the storage container.
Claim 13
Dependent Claim 24 words
System of claim 2, wherein batch-specific data of the test elements are located on the system alphanumerically, as bar codes or as magnetic strips.
Claim 14
Dependent Claim 15 words
System of claim 2, wherein the system when full contains 10 to 40 test elements.
Claim 15
Dependent Claim 17 words
System of claim 2, wherein the reset device automatically closes the opening by pressing on the flap.
Claim 16
Dependent Claim 27 words
System of claim 2, wherein the reset device has only one point of rest, and that point of rest is achieved when the flap closes the opening.
Claim 17
Dependent Claim 38 words
System of claim 14, wherein the reset device can be digitally engaged by a user to open the flap from the opening, and, upon digital disengagement, the flap automatically returns to a sealing position to seal the opening.
Claim 18
Dependent Claim 37 words
A system as claimed in claim 2, wherein said base structure contains test elements which are inserted in a position facing the opening of the system, from which they can be removed when the flap is opened.
Claim 19
Dependent Claim 40 words
A system as claimed in claim 2, wherein when said system is closed, said flap is pulled or pressed onto the opening of said base structure by said reset device, and the reset device is under tension at all times.
Claim 20
Dependent Claim 35 words
A system as claimed in claim 17, wherein the direction of the press of said reset device is substantially perpendicular to the rim of the opening of said base structure when said system is closed.
Claim 21
Independent Claim 18 words
A system as claimed in claims 1 or 2, wherein said reset device comprises at least one spring.
Claim 22
Independent Claim 95 words
A system for the storage of a plurality of test elements within the system, the test elements being for the analysis of sample liquids, the system comprising storage means having an opening said storage means for containing a plurality of test elements; holder means for holding the storage means, the holder means having an opening; flap means located on one end of the holder means, the flap means for sealing one of the openings against passage of water vapor; and reset means for pressing the flap onto said one of the openings to seal same.
Claim 23
