Dispensing head and a dispenser including the same

A dispensing head for a container containing a product, the dispensing head comprising:

• a portion defining at least one opening on the dispensing head for permitting dispensing of the product via the opening;
• and
• a valve configured to limit direct flow of air into the container via the opening and to permit dispensing of the product via the opening, the valve including
• at least one member movable between a first position limiting direct flow of air into the container via the opening and a second position permitting dispensing of the product via the opening, and
• a seat, the member contacting the seat when the member is in the first position and being spaced from the seat when the member is in the second position, wherein at least one of the seat and the member is formed of porous material, the porous material being impervious to the product and being capable of allowing passage of air into the container via the porous material.
