DETAILED DESCRIPTION

(9) Reference now will be made in detail to embodiments of the invention, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the invention, not limitation of the invention. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the invention. For instance, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.

(10) Generally speaking, the present invention is directed to a tie management system comprising an insert for managing the tie strings of a stack of surgical masks within a container. The insert has left- and right-side channels to segregate the respective left and right tie strings of the stack of surgical masks during packaging and to prevent the inadvertent dispensing of multiple face masks at once. Further, the tie management insert has a lower portion, an upper portion, a neck and a cut-out portion which form the channels. The neck comprises a fold region from which the lower portion is folded up toward the upper portion. The bottom edges of the stack of surgical face masks are configured to rest adjacent to the fold region. Further, the upper portion has left- and right-side flaps that are folded over the left- and right-side edges of the lower portion when the lower portion is folded upward at the fold region. The flaps of the upper portion secure the upper portion to the lower portion to hold the segregated tie strings, and thus the surgical masks, in place.

(11) Referring now to FIG. 1, a tie management insert 100 contemplated by the present invention is shown in a flat, unfolded configuration before the insert has been folded and secured about the tie strings in a stack of face masks. The insert 100 has an upper portion 102, a lower portion 104, and a neck 106 connecting the upper portion 102 and the lower portion 104. The insert 100 further has a cut-out portion 110 formed between the upper portion 102, the neck 106, and the lower portion 104. The cut-out portion 110 includes a first channel 108a and a second channel 108b. The neck 106 may also define a fold region where the insert 100 may be folded such that the lower portion 104 is folded up toward the upper portion 102. Specifically, the fold may occur at the crease 112 located on a portion of the neck 106 adjacent to the lower portion 104. The crease 112 may approximately bisect a height h.sub.1 of the insert 100, although it is to be understood that the crease 112 may be located anywhere along a height h.sub.2 of the of the neck 106. The crease 112 may be generally perpendicular to a central axis or midline M of the insert 100. The upper portion 102 of the insert 100 further includes a first flap 114a and a second flap 114b which are used to secure the upper portion 102 to the lower portion 104 when the insert 100 is in the folded configuration. The first and second flaps 114a and 114b each extend wider than respective first and second side edges 118a and 118b of the lower portion 104. The first flap 114a and second flap 114b have first and second fold lines 116a and 116b, respectively. The fold lines 116a and 116b are approximately parallel to and can be aligned with the first and second side edges 118a and 118b of the lower portion 104.

(12) The insert 100 can be formed in one piece out of a paper, stock, or cardboard material. The insert can also be formed in one piece out of a rigid or semi-rigid plastic material. In one embodiment, a single layer of material is used. As will be demonstrated below, no adhesive or fastener is required or used to hold the insert 100 in its final folded configuration.

(13) As shown in FIG. 1, the lower portion 104 has an outer width w.sub.1 extending between the first and second side edges 118a and 118b of the lower portion 104. The neck has an inner width w.sub.2. The upper portion 102 has an outer width w.sub.3. The flaps 114a and 114b each have a flap width w.sub.4. The sides of the lower portion 104 extending wider than the inner width w.sub.2 of the neck 106 have a width w.sub.5. As mentioned above, the insert 100 has an overall height h.sub.1 and the neck 106 and the channels 108a and 108b of the cut-out portion 110 have a height h.sub.2. The lower portion 104 has a height h.sub.3. The upper portion 102 has a height h.sub.4.

(14) The outer width w.sub.1 of the lower portion 104 may range from about 7 inches (17.8 cm) to about 10 inches (25.4 cm), such as from about 8 inches (20.3 cm) to about 9 inches (22.9 cm). In one particular embodiment, the outer width w.sub.1 of the lower portion 104 may be about 8.6 inches (21.84 cm). The inner width w.sub.2 of the neck 106 may range from about 2.5 inches (6.35 cm) to about 4.5 inches (11.4 cm), such as from about 3 inches (7.6 cm) to about 4 inches (10.2 cm). In one particular embodiment, the inner width w.sub.2 of the neck 106 may be about 3.33 inches (8.46 cm). The ratio of the width w.sub.2 of the neck 106 to the width w.sub.1 of the lower portion 104 may range from about 1:1.5 to about 1:4. The outer width w.sub.3 of the upper portion 102 may range from about 10 inches (25.4 cm) to about 14 inches (35.6 cm), such as from about 11 inches (27.9 cm) to about 13 inches (33 cm). In one particular embodiment, the outer width w.sub.3 of the upper portion 102 may be about 12 inches (30.48 cm). The ratio of the width w.sub.1 of the lower portion 104 to the width w.sub.3 of the upper portion 102 may range from about 1:1 to about 1:2. The flap width w.sub.4 may range from greater than 0 inches (0 cm) to about 2 inches (5.1 cm). The width w.sub.5 of the sides of the lower portion 104 extending wider than the inner width w.sub.2 of the neck 106 may range from about 1.25 inches (3.2 cm) to about 3.75 inches (9.5 cm). The height h.sub.1 of the insert 100 may range from about 5 inches (12.7 cm) to about 10 inches (25.4 cm), such as from about 6 inches (15.2 cm) to about 9 inches (22.9 cm). In one particular embodiment, the height h.sub.1 of the insert 100 may be about 7.5 inches (19.05 cm). The height h.sub.2 of the neck 106 and the channels 108a and 108b of the cut-out portion 110 may range from about 1 inch (2.5 cm) to about 3 inches (7.6 cm), such as from about 1.5 inches (3.8 cm) to about 2.5 inches (6.6 cm). In one particular embodiment, the height h.sub.2 of the neck 106 and the channels 108a and 108b may be about 2 inches (2.08 cm). In addition, the height h.sub.3 of the lower portion 104 can be approximately one half the total height h.sub.1 of the insert.

(15) Next, FIG. 2 shows a rear view of an exemplary stack of masks 200 that can be secured by the insert 100 of the present invention. The stack of masks 200 includes rectangular-shaped mask bodies 202 formed of conventional surgical mask material, such as a multi-layered material which is permeable to air. The mask bodies 202 have a bottom edge 210. Attached to an upper edge of each of the mask bodies 202 is an eye shield 208 formed of substantially transparent, flexible material. The mask bodies 202 each have a means for securing the mask on the face of the wearer. Advantageously, this can be a pair of tie strings on each side of the surgical mask body 202 forming left tie strings 204 and right tie strings 206. Moreover, it is to be understood that although the means for securing the mask is shown as a pair of left 204 and right 206 tie strings, tie strings or other elongated fasteners may be present in other quantities than those specifically shown in FIG. 2.

(16) Turning now to FIGS. 3-6, the steps for assembling the insert 100 to secure the tie strings of the stack of masks 200 are illustrated.

(17) First, the insert 100 is positioned over the back of the stack of masks 200 such that the upper portion 102 of the insert 100 contacts the rear of the rectangular mask bodies 202. The left-side tie strings 204 are gathered and pulled through the first channel 108a of the insert 100, and the right-side tie strings 206 are gathered and pulled through the second channel 108b, such that the left-side tie strings 204 and the right-side tie strings 206 lay on top of the lower portion 104 of the insert 100, as shown in FIG. 3. The free ends of the tie strings 204 and 206 extend distally away from the neck 106 and crease 112.

(18) Next, the insert 100 is folded along the crease 112 so that the lower portion 104 is folded upward to face the upper portion 102. At the same time, the gathered left-side tie strings 204 and right-side tie-strings 206 are brought upward such that the left-side tie strings 204 and the right-side tie strings 206 lay on top of the upper portion 102 and the eye shields 208, as shown in FIG. 4, so that the free ends of the tie strings 204 and 206 remain extending distally from the neck 106 and crease 112. In this configuration, the flaps 114a and 114b of the upper portion 102 extend out toward the left and right sides, respectively, wider than the width w.sub.1 of the lower portion.

(19) Finally, the first flap 114a is folded along fold line 116a towards the central axis or midline M of the insert 100 such that flap 114a contacts and secures the first side edge 118a of the lower portion 104, and the second flap 114b is folded along fold line 116b towards a central axis or midline M of the insert 100 such that flap 114b contacts and secures the second side edge 118b of the lower portion 104, as shown in FIG. 5. In this final folded configuration of the tie management insert system, the stack of masks 200 is secured within the folded insert 100. The left- and right-side tie strings 204 and 206 remain secured in their respective channels 108a and 108b and segregated from each other. The tie strings are further segregated from the mask bodies 202 so that the groups of tie strings 204 and 206 are secured from being pulled out by the dispensing of a mask.

(20) FIG. 6 illustrates a front view of this final folded and secured configuration. In this configuration, only one mask of the stack of masks 200 is visible from an exposed surface for access at any given time.

(21) As shown in FIG. 7, the final folded and secured stack of masks 200 about the insert 100 may then be inserted into any suitable package or dispenser 302 as part of a face mask dispensing system 300. The dispenser 302 may include an aperture 304 through which the front mask of the stack of masks 200 is exposed and may be removed, as seen in FIG. 7. As the front exposed mask is removed, the tie strings 204 and 206 connected thereto slide through the channels 108a and 108b of the insert 100 and out the aperture 304. The segregated channels 108a and 108b therefore prevent the ties 204 and 206 from becoming entangled with one another and allows smoother release of the mask from the dispenser 302. As a result, the removal of the front mask of the stack of masks 200 will not result in the removal or handling of other masks in the stack 200.

(22) The tie management insert 100 of the present invention significantly reduces the occurrence of both packaging defects and dispensing errors of a stack of masks 200 within a box or container in the clinical setting.

(23) Samples of three different types of dispensers for surgical masks were tested to evaluate the reduction in waste generated by the tie management insert of the present invention (Code H) as compared to a current mask dispenser (Code C) and a leading competitor's mask dispenser (Code R). In the study, dispensers were place on a shelf that simulated a hospital operating room scrub area. Healthcare professionals, who were the test subjects, were instructed to dispense a mask as they would in a clinical environment. The test results are provided in Tables 1 and 2 below.

(24) TABLE-US-00001 TABLE 1 Dispensing Errors Total Dispensed % of Dispensing Errors Code C 42 210 20.0% Code H 8 200 4.0% Code R 7 99 7.1%

(25) As shown in Table 1, the tie management system of the present invention (Code H) yielded significantly fewer dispensing errors as compared to the current and competitive mask dispensers.

(26) TABLE-US-00002 TABLE 2 Packaging Errors Total Dispensed % of Dispensing Errors Code C 33 210 15.7% Code H 8 200 4.0% Code R 7 99 7.1%

(27) As shown in Table 2, the tie management system of the present invention (Code H) yielded significantly fewer packaging defects as compared to the current and competitive mask dispensers.

(28) Due to the significant reduction in both dispensing errors by healthcare professionals, and packaging defects of the mask dispenser, the tie management insert system of the present invention had a significant reduction in overall waste as compared to the current and competitive mask dispensers.

(29) This written description uses examples to disclose the invention, including the best mode, and also to enable any person skilled in the art to practice the invention, including making and using any devices or systems and performing any incorporated methods. The patentable scope of the invention is defined by the claims and may include other examples that occur to those skilled in the art.
