Drying system for personal hydration systems

A drying system for drying a first personal hydration system having a first fill opening and a second personal hydration system having a second, larger fill opening, the drying system comprising:

• a housing;
• an air intake;
• an air outlet;
• a fan disposed in the housing and forcing air from upstream at the air intake to downstream at the air outlet;
• wherein the housing comprises a first wall portion sized to engage with the first fill opening of the first personal hydration system and a second wall portion located upstream of the first wall portion and sized larger than the first wall portion so as to engage with the second, larger fill opening of the second personal hydration system;
• and
• a seal-forming structure on the second wall portion sealing with the second fill opening;
• wherein the seal-forming structure comprises a resilient cam arm;
• wherein the housing comprises an inner wall portion, wherein the second wall portion lies coextensively with the resilient cam arm so as to define a channel between the resilient cam arm and the inner wall portion.

• wherein the housing comprises a second wall portion located upstream of the first wall portion and offset outwardly relative to the first wall portion so as to engage with the fill opening of the second personal hydration system;
• an internal seal-forming structure on the first wall portion sealing with the first fill opening;
• and
• an external seal-forming structure on the second wall portion sealing with the second fill opening, the external seal-forming structure comprising a resilient cam arm that can be flexed inwardly to accommodate insertion of the second wall portion into the second, larger fill opening and that flexes outwardly to seal with the second, larger fill opening.
