Abstract: An open top fully adjustable chef's hat preferably made of paper or paper equivalent. The hat comprises an upright preferably pleated sidewall adapted to be formed into a closed generally curvilinear shape. An adjustable headband is attached to the lower part of the pleated sidewall and adapted to adjustably fit a range of head sizes. A stiffening strip is attached to the upper part of the sidewall with at least part of the strip positioned in the interior of the hat when it is assembled. The free ends of the flap are adapted for overlapping telescoping fit of one end of the flap within the other. A foldable flap is provided on the headband to facilitate sliding assembly of one end of the headband inside the other.

Abstract: An adjustable disposable cap which includes a headband and an accordion pleated crown. The headband is folded to form an outer panel and upper and lower longitudinally extending inner panels. The headband is further folded to form a central section and two end sections with the first of said end sections of said headband being slideably insertable into the other section of said headband so that the first end is moveable with respect to the other end. An accordion pleated crown is folded to form four panels in the crosssectional configuration of a “M” or “W”. The lateral two panels of the crown are adhesively attached to the lower or upper inner panel of the headband at the central section and at the second of the two end sections of the headband. The first of the two end sections remains substantially free of the crown so that the head size of the cap is adjustable.

Abstract: An adjustable cap includes a pleated crown whose central pleats have less transverse dimension than the lateral pleats to better maintain the contour of the crown for front and rear head room for relatively small cap sizes. The pleats are secured to each other at the rear of the cap to prevent exposure of the head between the crown and headband.
