United States Patent Oflice 3,390,405 Patented July 2, 1968 3,390,405 CAP CONSTRUCTION William Joseph Gruber, 88 Oriole St., New Orleans, La. 70124 Filed .Ian. 29, 1965, Ser. No. 429,083 2 Claims. (Cl. 2-197) This invention relates to an improved article of headwear, and in particular, an inexpensive disposable cap construction.

Workers and operators in the food service industry, such as restaurants, bakeries, food processors, etc., find it customary or necessary to wear various types of head coverings to maintain optimum sanitary conditions when handling food. The hair of the wearer is thus prevented from falling and mingling with the food being processed. Many fields of industry unrelated to the food service field must also adhere to strict sanitary regulations.

Fabrics or other materials requiring cutting and sewing operations have heretofore been used in making caps or head coverings for sanitary wear and thus involve high production costs. These articles necessitate repeated laundering, adding substantially-to their ultimate cost.

It is thus an object of the present invention to provide an inexpensive disposable cap or hat construction in which paper is the basic material employed in the manufacture thereof. The cap provides an attractive appearance when worn, and offers adequate sanitary protection. After a period of wear the cap may, upon becoming soiled, be discarded and replaced by a new and clean cap manufactured at low cost.

Another object of this invention is to provide a cap construction formed from relatively inexpensive materials, such as paper, and which is capable of being manufactured with the use of high speed automatic machinery.

It is a further object of this invention to provide a paper cap having a headband which may be adjusted readily to different head sizes.

Further objects and advantages of the invention will become apparent from the following description and claims, and from the accompanying drawings wherein:

FIGURE 1 is a perspective view of the paper cap construction comprising the subject matter of the present invention.

FIGURE 2 is a side view in elevation of the paper cap construction illustrated in FIGURE 1.

FIGURE 3 is a cross sectional view taken substantially along the plane indicated by the line 3-3 of FIGURE 2.

FIGURE 6 is a cross sectional view taken substantially along the plane indicated by the line 6-6 of FIG- URE 4.

FIGURE 7 is a cross sectional view taken substantially along the plane indicated by the line 77 of FIGURE 5.

FIGURE 8 is a side view in elevation of a paper blank from which the cap of the present invention is formed.

FIGURE 9 is a side view in elevation of the paper blank of FIGURE 8 folded along horizontal fold lines to form the band of the cap, and further illustrating the manner in which an adhesive is applied to the blank for securement of the crown of the cap to the headband.

FIGURE 10 is a perspective view of the paper crown of the cap.

Referring now to the drawings in detail, wherein like numerals indicate like elements, the cap comprising the subject matter of the instant invention is generally designated by the numeral 10. The cap includes a paper headband 12 and a substantially M-shaped crown 14 of tissue paper. The headband 12 of the cap 10 may include a suitable decorative design such as is indicated at 16.

Referring now specifically to FIGURES 8-10, the headband .12 of the cap 10 is formed from a blank 18 of a relatively heavy grade of paper. The blank 18 is provided with spaced

horizontal fold lines

20, 22, and 24. The blank 18 also includes spaced

vertical fold lines

28, 30 and 32.

The blank 18 is first folded along the

horizontal fold lines

20 and 22 to form a substantially U-shaped channel 26 along the length of the blank. Then the top of the blank 18 is folded downwardly about horizontal fold line 24. The resultant structure is illustrated in FIGURE 9.

An adhesive substance 34 is applied along the length of the blank 18 to form an adhesive strip. As shown in FIGURE 9, the adhesive strip 34 extends from one free end of the blank along its length to a point spaced from the vertical fold line 30 and the other free end of the blank 18. The length B of blank 18, illustrated in FIGURE 9, is free from adhesive.

After the blank 18 has been folded about the horizontal fold lines and the adhesive 34 applied, the blank is folded about the

vertical fold lines

28, 30 and 32, in that order. The portion of the blank 18 between the

vertical fold lines

28 and 30 forms a first, substantially fiat rectangular panel 36 of the headband 12. The remaining portions of the blank 18 are adapted to form a second, substantially fiat, rectangular panel 38 spaced from the first rectangular panel 36.

The second rectangular panel 38 includes a first flap 40 extending from the vertical fold line 28 to the free end 44 of the blank 18, and a second flap 42 extending from the vertical fold line 30 to the free end 46 of the blank 18. As illustrated in FIGURES 3-7, the flap 42 is telescoped within the second flap 40 to form the second rectangular panel 38 of the headband 12. The fold 24, the inner surface of flap 40, and the U-shaped channel portion 26 on the flap 40 prevent the flap 42 from separating from the flap 40 in a direction perpendicular to the length of the flaps, and thus maintains their telescopic engagement.

By moving the flap 42 relative to the flap 40, the length of the perimeter of the headband 12 may be adjusted to fit the head of the wearer of the cap 10. Indicia 54 is pro vided along the inner surface of the channel 26 of the flap 42 for indicating the cap size of the headband 12 as the flap 42 is moved relative to the flap 40.

A tissue paper crown generally designated by the numeral 14 is provided to complete the cap 10. As illustrated in FIGURE 10, the tissue crown 14 is substantially M-shaped in cross section and includes

outer extremities

48 and 50.

The flat

rectangular panels

36 and 38 are adapted to be spread apart laterally relative to each other to define a central opening 56 for receiving the head of the wearer of the cap 10. The

outer extremities

48 and 50 of the crown 14 are adapted to be connected to the inner surfaces of the

rectangular panels

36, 38, respectively, by pressing the bottom portions of the outer extremities along the adhesive strip 34 surrounding the inner periphery of the headband 12. The crown 14 thus substantially closes one end of the opening 56.

The crown 14 is connected to the headband 12 when the headband has been adjusted to its largest size. A portion of the outer extremity 50 of the crown 14, designated by the letter A, coincides with a portion of length B on the inner surface of the flap 42 which lacks adhesive, and thus remains unconnected to the inner periphery of the headband 12.

Because of the unsecured length A of the crown 14, adjustment of the headband size by telescopic movement of the

flaps

40, 42 is possible. When the

flaps

40, 42 are moved relative to each other to substantially decrease the 3 length of the perimeter of the headband 12, for example, as illustrated in FIGURES 5 and 7, the free portion A of the crown 14 is adapted to collapse in accordion-type fashion to form a series of pleats 52. If the crown 14 were secured along its total outer extremity 50 to the inner surface of the rectangular panel 38, either relative telescopic movement of the flaps 4t) and 42 would be impossible, or the crown 14 would be torn. When the headband 12 is adjusted from a smaller or intermediate size to a larger size, the pleats 52 will tend to straighten during the telescopic movement.

Since the crown 14 is substantially M-shaped in cross section, it can be spread laterally to conform to the breadth of the wearers head.

The vertical fold line 31 allows free movement of the flap 42 into the flap 40 and permits an additional length of telescopic action to increase the variable range of the perimeter of the headband 12.

If desired, the paper material between the

horizontal fold lines

20 and 22 may be coated with paraffin or comparable treating material to render it moisture-resistant, since this portion of the headband 12 will act as the sweatband of the cap and constitute its inner lining.

Since the cap 10 is made completely from paper material it is relatively inexpensive and need not be subjected to repeated laundering. After a period of wear, the cap upon becoming soiled, can be discarded and replaced -by a new and clean cap manufactured at low cost. Due to the simple folding operations in constructing the cap, it is susceptible of being formed on high speed automatic machinery. The cap is adjustable to fit snugly the head of the wearer, the adjustment being accomplished by simply contracting or expanding the headband portion 12 of the cap 10.

While a specific embodiment of the invention has been disclosed in the foregoing description, it will be under stood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention except as defined by the scope of the appended claims.

I claim:

1. A cap construction comprising a headband, said headband including an elongated paper blank folded along a pair of spaced vertical fold lines to define the ends of and form a first substantially rectangular panel, and a pair of flaps, each flap being connected to the ends of said rectangular panel and having free ends, means on said blank formed 'by folding said blank along horizontal fold lines for telescopically connecting the free ends of said flaps to form a longitudinally adjustable second rectangular panel, a third vertical fold line on said first panel adjacent one of said vertical fold lines defining an end of said first rectangular panel for providing unencumbered relative movement of said flaps, said first and second rectangular panels being spaced from each other to define a central opening for receiving the head of the cap wearer, and a paper crown, said paper crown having outer extremities along its length adhesively connected to said first and second rectangular panels except between said vertical fold line defining the end of said first rectangular panel adjacent said third vertical fold line and the telescopic connection of said flaps, whereby said crown may be bunched along one of its extremities in accordion-type fashion to permit adjustment of its length and the telescopic movement of said flaps.

2. A cap construction in accordance with claim 1 wherein said paper crown is substantially M-shaped in cross section whereby said crown may be extended in a direction perpendicular to its outer extremities to adjust the breadth of the cap.
