Abstract

A package which incorporates, integrated in the composition of one of the components of the test'"'"'s package, a plastic base (1), a moisture absorbing agent, so that this does not affect them, in combination with one or more polymers, which may be packaged in a blister produced by a base sheet (7) with structures which give rise to cavities (9), in each one whereof a rapid diagnostic test (5) is placed, whose base sheet (7) is complemented with a cover sheet (8) which seals the previous by heat fusion, achieving the hermeticity of each cavity.

Claims

1. A blistered rapid diagnostic test characterized in that it comprises:

a base (1);

a structure (2);

a rapid diagnostic test (5, 5′

) between said base and said structure;

a moisture absorbing agent integrated in the test;

a base sheet (7) having at least one structure determining at least one cavity so as to define a blister receiving said test;

a cover sheet (8) which is fixed by heat fusion to the base sheet (7), so as to determine a seal of each the at least one cavity (9, 9′

) containing the rapid diagnostic test (5, 5′

).

2. The blistered rapid diagnostic test of claim 1 wherein the moisture absorbing agent is integrated with the base (1) in combination with at least one polymer.

3. The blistered rapid diagnostic test of claim 1 having a binding area (6) wherein the moisture absorbing agent is integrated with the handling area (6) in combination with at least one polymer.

4. The blistered rapid diagnostic test of claim 1 comprising a punch-hole (12) adjacent to one end of the blister whereby the base sheet (7) and the cover sheet (8) are separated to permit easy gripping and pulling of the cover sheet (8) in an opening operation of the corresponding unit.

5. The blistered rapid diagnostic test of claim 1 wherein said at least one cavity consists of a single cavity (9, 9′

) determining a single independent unit accommodating a rapid diagnostic test (5, 5′

).

6. The blistered rapid diagnostic test of claim 1 wherein said at least one cavity consists of a plurality of cavities (9, 9′

), each cavity determining a unit accommodating a rapid diagnostic test (5, 5′

), said units being independently hermetic and

a plurality of weakened tear lines (10, 10′

) provided between each two cavities (9, 9′

) to facilitate separation of the units.

7. The blistered rapid diagnostic test of claim 1 further comprising an area where the cover sheet (8) is fixed by heat fusion to the base sheet (7) having a surface with ribs (11) by way of knurling, so as to improve sealing of the cover sheet (8).

8. The blistered rapid diagnostic test of claim 6, further comprising an areas (13) which is adjacent to the weakened tear lines (10′

) of each unit and collateral to each of the cavities (9′

), showing printed data selected from control data, information data and combinations thereof.

9. The blistered rapid diagnostic test of claim 1 further comprising adhering means for adhering the base (1) to the structure (2) and wherein the base (1) is directly adhered to the structure (2) by the adhering means.

10. The blister rapid diagnostic test of claim 1 further comprising adhering means for adhering the base (1) to the structure (2), said adhering means comprising a double-sided adhesive (3) acting as a separation between the structure (2) and the base (1).
