Door panel and a stile thereof

A door panel comprising:

• a body comprising front and rear door skins sandwiching, at least partially, a first stile and a second stile separate from the first stile;
• the first and second stiles together being configured to delimit an interior of the door panel configured to receive an injection of filing material,
• wherein at least one of the first and second stiles comprises a hollow structure with a partitioned hollow interior that extends along substantially an entire length of the body and providing mechanical strength to the body and providing a foundation for installing door fittings,
• wherein adjacent the hollow structure is a portion to be varnished integrally formed therewith as one piece,
• wherein the front and the rear door skins engage respective outer surfaces of the stiles through an engagement between cooperating sets of male and female members,
• wherein the male members are arrayed over and extend from the front and rear skins and each of the male members engages with a cooperating corresponding one of the female members,
• wherein each female member is provided on outer surfaces of the stile and at the portion to be varnished, and the female member is in the form of a groove defined between two walls of one of the stiles, the groove is configured such that upon insertion of one of the male members in the groove of a corresponding one of the female members, at least one of the two walls defining the groove presses against the male member in the groove to form a fluid tight engagement;
• and
• the at least one of the two walls extends along an axis inclined at an angle with respect to a direction of insertion of the male members such that a top portion of the at least one of the two side walls defining a respective female member closer to an outer side of the stile presses against a corresponding male member but a remaining portion of the at least one of the two side walls defining the respective female member is free of contact with the corresponding male member;
• the portion to be varnished includes an internal void isolated from the hollow interior of the hollow structure so as to reduce overall thickness of the portion to be varnished.
