BACKGROUND OF THE INVENTION

1. Field of the invention

The invention concerns techniques for using bands made of sheet materials to make loops whose sizes are adjustable.

2. Description of related art

Bands made of sheet materials are often attached to items to identify them. One way of attaching the band to the item is to loop the band around part of the item. Examples of identification bands used in this fashion are the bands used to identify nursery stock, which are looped around the trunk or a branch of the nursery stock, and the wristbands used to identify patients in hospitals. Such bands need to be easily adjusted to make different-sized loops. In many cases, it is also important that the loop closely fits the object it is looped around and that there are no dangling ends. Examples of prior-art solutions to these problems may be found in U.S. published patent application 2004/0237366, Chadwick, et al., Identification bracelet, and U.S. Patent 6, 641,048, Schintz, et al., Winged wristband. Finally, there are situations in which it is advantageous to make the loop in advance and then be able to adjust the loop to an exact fit after it has been placed on the object. It is

an object of the techniques disclosed herein to provide bands made of sheet materials which are easily adjusted to closely fit an object, may be made up in advance, and which have no dangling ends.

BRIEF SUMMARY OF THE INVENTION

The foregoing object is attained by apparatus for forming a band into a persistent loop. The apparatus is made up of a hole portion of the band which contains a hole, a tongue portion of the band which fits through the hole, and adhesive attachment area on one or the other or both of the portions. To persistently form the band into a loop, one passes the tongue portion through the hole and attaches the adhesive attachment area to the loop's outer surface.

Other aspects of the apparatus may include the following:

• the tongue portion has a length which permits the size of the loop to be varied by varying the amount of the tongue portion which is passed through the hole. • The tongue portion includes structures for mechanically engaging the hole, which permits the band to be temporarily formed into a loop prior to being persistently formed into the. The structures may be the edges of the tongue.

• information areas which may be on the outside of the hole portion or on the outside of the tongue portion.

Another aspect of the techniques is business forms which include bands which implement the above apparatus. The business forms may include other entities that are linked to the bands by means of identification information which appears on both the bands and the other entities. The other entities may be labels or bands for persons who are associated with the wearer of a band which has the above apparatus. Yet another aspect of the invention is methods of forming bands which implement the above apparatus into loops.

Other objects and advantages will be apparent to those skilled in the arts to which the invention pertains upon perusal of the following Detailed Description and drawing, wherein:

DETAILED DESCRIPTION OF THE INVENTION

A wristband which can be made up in advance, is adjustable to fit, and has no hanging ends

Fig. 1 shows a presently-preferred embodiment of a wristband which is made using the techniques disclosed herein. The presently-preferred embodiment of the wristband is designed for use in an institutional environment and is made of a sheet material which is waterproof and is resistant to solvents which are commonly employed in such environments. An example of such a sheet material is a cross laminated polyethylene film such as VALERON® produced by Valeron Strength Films of Houston Texas. The sheet material may further have a coating which renders water-based inks such as those used in ink-jet printers and marking pens water and solvent resistant. For details, see U.S. published patent application 2004/0237366. The sheet material may also be a material that is designed for use in Laser printers and is based upon polyesters or laminates of polyesters and polyolefins. An example of a film such as this would be "Tough paper " offered by Hewlett Packard Corporation or a custom-constructed material having the necessary properties. The sheet material employed for a particular embodiment of the bands will of course depend upon the use to which the bands are to be put.

FIG. 1 shows band 101 from which the preferred embodiment of the wristband is made. Band 101 has two major components: hole portion 103, which contains hole 109, and tongue portion 105. To make band 101 into a wristband, one inserts the end 115 of tongue portion 105 into hole 109.

Tongue 105 is slightly wider than the diameter of hole 109. Consequently, tongue 105 must be bowed slightly to insert it into hole 109. The material of which wristband 101 is made has a stiffness which is approximately that of writing paper. Because tongue 105 is bowed slightly, the stiffness of the wristband's material urges the edges of tongue 105 against the edge of hole 109. The stiffness of the wristband's material also tends to force the loop made by passing tongue 105 through hole 109 to open, and the interaction between the edges of tongue 105 and hole 109 resists the tendency of the loop to open. Because of the interaction between the edges of the hole and the edges of tongue 105, band 101 may be premade into a temporary loop which has an adjustable size. The effect of the interaction between the edges of tongue 105 and hole 109 may be increased by including a slightly wider portion 113 in tongue 105. A wristband which has been premade from band 101 is shown at 117. The loop formed by the wristband has an outer surface 119 and an inner surface 121.

Hole portion 103 further includes information area 111, which contains information that has been written or printed on band 101, and adhesive attachment area 107. Information area 111 and the adhesive of adhesive attachment area 107 are on opposite sides of band 101; in the top view of band 101 of FIG. 1, the adhesive is on the other side of the band 101. When the wristband is finished, information area 111 will be on outer surface 119 of the loop. To give a wristband 117, premade or otherwise, its proper size, one places the wristband on the patient's extremity and pulls tongue 105 through hole 109 until the proper fit is obtained. Then one attaches adhesive attachment area 107 to outer surface 119 of the loop. The attachment of adhesive attachment area 107 to outer surface 119 gives the loop a persistent size. How persistent the size is will of course depend on the application for which the wristband is intended. Once the adhesive attachment area is attached, the portion of tongue 105 which protrudes beyond hole 109 may be cut off. If tongue 105 is cut off where it emerges from hole 109, the cut end will be retained by the edges of hole 109 and will not protrude above the outer surface of the wristband. In other versions, tongue 105 may include an adhesive attachment area at its end and the adhesive attachment area may be used to attach the end of tongue 106 to the outer surface of the loop.

Many variations of band 101 are possible. Fundamental to all of them are that the size of the band is adjusted by pulling tongue portion 105 through hole 109 and that the band is given its permanent size by attaching an adhesive attachment area to the outer surface of the loop. The adhesive

attachment area may be on hole portion 103, as is the case with band 101, it may be on tongue portion 105, or there may be adhesive attachment areas on both hole portion 103 and tongue portion 105. The adhesive attachment areas may also include tabs which can be bent over and attached to the inner surface of the loop. The information area may be on hole portion 103, as in band 101, or on tongue 105.

Exemplary versions of band 101: FIG. 2

FIG. 2 shows versions 101(a) through 101(g) of a band 101. In all of these versions, there are two adhesive attachment areas: adhesive attachment area 107 on hole portion 103 and adhesive attachment area 203 at the end of tongue 105. In all of these versions, information area 111 is on tongue 105. As with band 101, information area 111 and the adhesive belonging to the adhesive attachment areas are on opposite sides of the band. Other variations include adhesive attachment areas with tabs as shown at 205 and 207 and different forms of hole 109, including a curved slit 205. An important consideration in the selection of a shape for hole 109 is that the shape is one which does not tend to serve as a starting point for tears in the material from which the band is made. For cross laminated polyethylene and polyester films, the circle is such a shape.

An exemplary use of band 101: FIG. 3 A use of band 101 which illustrates the value of being able to premake the loop is shown in FIG. 3. FIG. 3 is used to train nurses in the use of band 101 with newborn babies. To prevent mistakes in identifying the babies, the newborn must receive its identification wristband immediately after birth, before the newborn has been washed. At this point, the newborn is slippery and hard to handle. The figure shows the procedure 301 for placing the identification wristband on the baby. First, the band is printed (303). Then it is premade by placing tongue 105 through hole 109 and set aside (305). When the baby is born, the premade wristband is placed over the baby's wrist or ankle (305). Then the tongue is grasped and pulled to tighten the wristband to its permanent size (307). Next, adhesive attachment area 107 is attached to the band (309). Finally, tongue 105 is trimmed off at hole 109 (311).

A business form containing an array of bands 101: FIGs. 4 and 5

Bands 101 may be distributed as printable business forms. FIG. 4 shows such a business form 401 that contains two bands 101 and a label 403. The bands and the label 403 will be printed with

identification information that relates the label and the band. Business form 401 is made up of two layers: a layer of the material from which the bands are made and a release layer. The bands and the label have been diecut in the layer of material and adhesive has been applied to the bands' adhesive layers. The release layer is coated with a substance that the adhesive does not attach to. The printer on which business form 401 is printed is set up to print identification information on the proper areas of the bands. When the band is used, it is separated from the form along the diecut lines.

FIG. 5 shows the kinds of identification information that is typically placed on the bands. FIG. 5 is a maternity business form that has two adult bands 503 and 505 for the parent(s) of the child, two newborn bands 507 for the child, and a label 509 which can serve to identify the child's crib. All of the wristbands have the name, picture, and barcode for the person identified by the wristband. Band 503 for the mother further includes a picture of the baby and the baby's name and barcode. Other information includes the responsible doctor and medical warnings.

Conclusion

The foregoing Detailed Description has disclosed to those skilled in the technologies to which Applicant's techniques pertain how to make and use bands embodying Applicant's techniques and has further disclosed the best mode presently known to the inventor of making and using bands according to his techniques. As will be immediately apparent to those skilled in the relevant technologies, countless other embodiments may be made that employ the techniques disclosed herein. Bands having the hole portion, tongue portion, and adhesive on one or the other or both of the portions can be made of any sheet material. The longer the tongue portion relative to the hole portion, the greater the range of sizes that the loop made from the band may have. Any technique which permits the tongue portion to engage the hole portion may be used to temporarily make the bands into loops. For example, the end of the tongue portion may have an easy release adhesive such as that used on Post-it® notes. If the sheet material has approximately the stiffness of paper, it becomes easier to pass the tongue through the hole. Material of such stiffness also permits hole engagement techniques in which the stiffness of the material causes the edges of the tongue to engage the edges of the hole. The hole may have any shape that is resistant to tearing in the kind of sheet material employed in the bands. The kinds of sheet materials used and other details of other embodiments will depend primarily on the purposes for which the bands are to be used. For all of

the foregoing reasons, the Detailed Description is to be regarded as being in all respects exemplary and not restrictive, and the breadth of the invention disclosed herein is to be determined not from the Detailed Description, but rather from the claims as interpreted with the full breadth permitted by the patent laws.
