A packaging element (110) for packaging medical consumables (112) is disclosed. The packaging element (110) comprises: a. at least one carrier sheet component (114) having formed therein at least one cavity (116) and having at least one rim (118) at least partially surrounding the cavity (116); b. at least one barrier (120); and c. at least one sealing sheet material (122) configured for being coupled at least partially to the rim (118) of the at least one carrier sheet component (114) and for sealing the at least one cavity (116), - wherein the at least one cavity (116) comprises at least one consumable compartment (124) for receiving the medical consumable (112) and at least one desiccant compart- ment (126) for receiving at least one desiccant (128), and - wherein the consumable compartment (124) and the desiccant compartment (126) are separated via the at least one barrier (120), the barrier (120) preventing desiccant (128) from entering the consumable compartment (124) and the barrier (120) allowing for water vapor moving from the consumable compartment (124) to the desiccant compartment (126). Further disclosed are a medical consumable kit (140), a method of manufacturing the medical consumable kit (140) and a use of the packaging element (110).

Resumen de: EP4628423A1
This container stores an addition-curing liquid silicone composition that contains a platinum catalyst that is activated by contact with the atmosphere, but is inactive in an atmosphere having a humidity of 5% RH or less and an oxygen concentration of 0.1 volume% or less. In the presence of this platinum catalyst that has undergone activation in the atmosphere, the addition-curing liquid silicone composition undergoes crosslinking and curing by a hydrosilylation addition reaction. The container has this addition-curing liquid silicone composition sealed (filled) thereinto, and the container comprises: a first sealing structure having a sealing part provided by sealing an inlet opening through which the addition-curing liquid silicone composition is introduced; a second sealing structure, that is a film that covers at least the entire sealing part of the first sealing structure or covers the entire first sealing structure, to further seal the sealing part; and a member having the ability to consume and remove the oxygen and moisture incidentally present between the first sealing structure and the second sealing structure. The storability of an aerobically curable addition-curing liquid silicone composition can thereby be improved.
