No. 859,404 Int. Cl. A42b 1/02, 1/04 U.S. Cl. 2--197 10 Claims ABSTRACT OF THE DISCLOSURE An improved cap construction of the disposable type formed of paper materials or the like, comprising an upper crown and a head band having front and rear panels, a pair of flaps in one panel having opposing free ends telescopically slidable within each other thereby providing means for head-size adjustment, and size locking means which comprises a pressure-sensitive adhesive placed behind an open Window near the free end of one of the flaps. When the flaps are interengaged to an adjusted position nger pressure applied to the non-sticky side of the adhesive brings the adhesive n one flap into contact with the other flap for immediate securement thereto. For additional securement, a second pressuresensitive adhesive mounted on the second flap, opposite the window in the first flap, is provided.
BACKGROUND OF THE INVENTION This invention relates to an improved article of headwear and more particularly to an inexpensive disposable cap construction having means for xedly adjusting the head size.
Participants in the food service industry, such as restaurants, bakeries, supermarkets, etc. find it customary or necessary to wear a head covering in order to maintain the required sanitary conditions when handling foodstuffs or the like. Such headwear is desired to prevent or minimize the hair of the wearer from falling and mingling with the food being processed or served. Certain industries other than the food industry also require adherence to strict sanitary regulations. For example, the so called white room facilities found in space-oriented industries impose more stringent housekeeping and sanitation provisions than generally found in the food industry. Since head coverings are generally provided it has been found economically desirable to provide inexpensive headwear of the disposable type rather than having to launder and maintain the more permanent variety of headwear previously used.
SUMMARY OF THE INVENTION This invention deals primarily with an attractive disposable cap or headwear formed completely of paper or paper-like materials offering an adequate measure of sanitary protection in use. Because of its low cost the cap may be discarded after limited use or when the cap is soiled. The economics of discarding are favorable when compared to the substantially higher initial cost of a cap made of a more permanent material such as cloth or the like when cleaning and maintenance costs are included therein.
It is, therefore, a primary object of the present invention to provide an inexpensive disposable cap designed for manufacture at low cost to be discarded after limited use and thereafter replaced by a new cap.
Another object of this invention is to provide a disposable cap having means for head size adjustment for accommodating wide ranges of sizes thereby reducing the inventory requirements of the consumer.
A further object of this invention is to provide a disposable cap of the character indicated having means for ice securing the adjusted headband so that it remains stationary after repeated use.
Still another object of this invention is to provide nexpensive locking means of the pressure-sensitive adhesive type which is hidden from view but when pressed externally is brought into contact with an opposing slidable flap thereby xedly securing the headband.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings in detail, wherein like numerals indicate like elements throughout the several views, the cap comprising the subject matter of the present invention is shown in perspective in FIG. 1 by the numeral 10. The cap includes a paper headband 12 and a crown 14 of tissue paper or the like. Although not shown, any suitable decorative design or indicia may be applied externally to headband 12 for advertising or decorative purposes. Headband 12 comprises spaced rear and front panels 13 and 15 respectively joined at their longitudinal ends. When the panels are opened a substantially continuous perimeter for receiving the wearers head is provided.
Now referring particularly to FIGS. 2 and 3, headband 12 of the cap 10 may be readily formed from a pliable sheet or blank 16 made preferably of a relatively heavy grade of paper. The blank 16 is generally rectangular in shape having upper, intermediate and lower portions 18, and 22 respectively, extending horizontally across the entire length with the upper and intermediate portions 18 and 20 being separated by a horizontal fold line 24, and the intermediate and lower portions 20` and 22 being separated by a second horizontal fold line 26; each of the portions 18, 20 and 22 being vertically subdivided by vertical fold lines 28 and 30.
In the subdivided area of the lower portion 22 bounded by fold line 28 and left edge 32, a substantially square opening or window 34 is formed near the left edge 32, the purpose of which will be more fully described hereinafter. Near the right edge 36 of lower portion 22 in the area bounded by fold line 30 and right edge 36, a pressuresensitive adhesive strip 40 may be adhesively secured to blank 16 in substantial horizontal alignment with window 34. Adhesive 40 is preferably of the pressure-sensitive strip type having tacky surfaces on both sides. Such material is commonly known as double-back tape and is commercially available in art supply stores or the like.
Above window 34 in the intermediate portion 20 another pressure-sensitive adhesive strip 42, also of the double-back variety is provided in substantial vertical alignment with the window 34. Thus, when lower portion 22 is folded about horizontal fold line 26 to a position shown in FIG. 3, the window 34 will overlie and circumscribe adhesive 42 in a manner which prevents the premature adhering of adhesive strip 42 during the size adjustment of headband 12, as will be later described.
It should be understood that although adhesives 40, 42 are preferably of the strip type any tacky latex adhesive may be used.
The headband 12 is formed by first folding blank 16 along the horizontal fold lines 24 and 26 to form a substantially C-shaped channel 46 extending the length of the blank 16, best seen in FIGS. 4 and 5. The resultant folded blank may be characterized as having an outer wall formed from the intermediate portion 20 and a spaced inner wall formed by upper and lower portions 18 and 22, the inner wall having a separation or slot shown at 49, the purpose of which will be later clarified. Thus, adhesive strip 42 is adhesively secured to the inner surface 48 of the intermediate portion 20 of headband 12 with its unsecured tacky surface facing inwardly towards the open window 34. The adhesive strip 40, however, is positioned on the inner surface 50 of the lower portion 22 of headband 12 with its unsecured tacky surface facing outwardly as best seen in FIG. 5.
'Ihe crown 52 preferably formed from a trapezoidal shaped tissue blank is adhesively secured adjacent its bottom inner edge to the headband 12 at a glue line 54 which is applied to headband 12 at 54. Alternatively, a glue line can be provided on crown 52. Any suitable glue or adhesive of the remoistening or latex variety may be used. Crown 52 is also provided with a glue line 56 along its upper end for sealing the crown after nal assembly of the cap.
As shown in FIGS. 6 and 8 the horizontally folded blank 16 with the crown 52 secured thereto is then folded about the vertical fold lines 28 and 30, forming a substantially flat rectangular rear panel 13 with the remaining Iportions forming flaps 60 and 62. Flaps 60 and 62, when finally formed constitutes the perviously described inner panel 15 which together with outer panel 13 form headband 12. The flap 60 may be slidably telescoped within the flap 62 by inserting the one free end 32 passed end 36 into the C-shaped channel adapted to freely receive same. Flap 60 is provided with sufficient length to prevent inadvertent removal from the channel 46 prior to locking. The added length enables any size adjustment to be readily accomplished by changing the inner perimeter of the headband 12.
As shown in FIG. 11, indicia 64 may be provided along the inner portions of the cap as an aid in adjusting the 4 cap size. Referring now to FIG. 12 it will be seen that the telescopic movement of the respective flaps 60, 62 is possible with crown 14 secured to headband 12 because of the slot 49 provided in channel 46. By this arrangement the crown 52 can slide obliquely through the opening 49 without interference.
FIGS. 9 and 10 illustrate the nally assembled cap with the aps in telescopically interengaged condition and with crown 14 sealed along its upper edge at glue line 56. An overlapping unsecured crown portion designated as A, is provided with the flaps 60, 62 permitting sufficient expansion of the crown when the flaps are adjusted for size. However, since the top of the crown is secured, the center will depress downwardly as the size of the hat increases, as seen in FIG. 1, resulting in a pleasing overseas cap appearance.
As initially assembled, seen in FIG. 9, headband 12 is provided with an adhesive-free area intermediate opposing adhesive strips 40, 42 and generally designated as B. As the flaps 60, 62 move outwardly in the direction increasing the hat size adhesive 40 and 42 are brought in to opposing relationship wherein subsequent contact can be effected. Thus, any restraint imposed by the secured crown portion in opposition to such expansion can be effectively absorbed by the opposing adhesive strips, after securement. The enlarged sectional view of such securement is shown in FIG. 12. Such securement or locking is easily achieved by merely pressing the flaps together at the position shown at 74 of FIG. 11 thereby bringing in contact adhesives 40 and 42.
It should be emphasized that window 34 plays an important roll in separating the tacky surfaces of the adhesives, thereby permitting slidable engagement of the aps. Headband 12 is generally constructed of heavy gauge material so that its thickness is considerably larger than that of adhesive strip 42. Since the adhesive strip 42 is placed behind the window 34 it will not extend beyond the thickness of the window until it is pushed inwardly or the opposite surface is pushed outwardly toward it. In FIG. l2 the adhesive strip 42 is brought into adhesive contact with adhesive strip 40 when nger pressure is applied at 74. If the window 34 was not provided or was of insufficient thickness the telescopic size adjustment would be impeded with premature locking of the flaps occurring.
Further, adhesive strip 40 may be entirely eliminated where the strength or holding power of adhesive strip 42 is sucient to permit locking of the flaps 60, 62 by the securing action of adhesive strip 42 on inner surface 50 of the flap 62.
From the foregoing description, it may be seen that a novel principle of telescopic adjustment and locking has been introduced into the headband of the present invention. This combination is especially important where the crown is without pleats or the like for expansion provided therewith tending to restore the ap to the unadjusted state. The locking means provided are hidden from view and of simple construction such that by merely pressing on the inside of the headband securement is rapid and effective. Hence, the cap comprising the present invention represents a step forward in the art of disposable headwear.
It should be understood that materials other than paper may be employed in the practice of the present invention, however, the cap is preferably formed from paper material, since cost is a primary consideration. No laundering or maintenance is therefore required. Due to the noncomplicated blank for both the headband and crown and the simple folding operations employed in constructing the cap, high speed automatic machinery may be readily used in producing this product.
