DETAILED DESCRIPTION

[0040] A first embodiment of a bedding arrangement 10 in accordance with the present disclosure is shown, for example, in Figs. 1, 2, and 6-8. Another embodiment of a bedding arrangement 110 in accordance with the present disclosure is shown, for example, in Figs. 9, 10, and 14-16. Still yet another embodiment of a bedding arrangement 210 in accordance with the present disclosure is illustrated, for example, in Figs. 17, 18, and 22-24. Another embodiment of a bedding arrangement 310 is shown, for example, in Figs. 25, 26, and 30-32. Bedding arrangements 10, 110, 210, and 310 block bed bugs 15 from biting a person 13 resting on bedding arrangements 10, 110, 210, and 310 while transporting moisture 11 away from the person 13 and into a space formed in each bedding arrangement 10, 110, 210, and 310 so that comfort of the person 13 is maximized.

[0041] Bedding arrangement 10, in accordance with the present disclosure, includes a mattress package 12 formed to include a mattress-receiving space 14 and a mattress 16 arranged to lie in the mattress-receiving space 14 as shown in Figs. 1, 4 and 5. In one illustrative example, mattress 16 may become infested with bed bugs 15 or other insects which may harm a person resting on mattress 16 or disrupt the person's sleep. Placing the infested mattress 16 and bed bugs 15 in the mattress-receiving space 14 and closing the mattress package 12 so that bed bugs 15 are trapped in the mattress- receiving space 14 causes the person to be isolated from bed bugs 15 and bed bugs to eventually die from starvation. As a result, the person 13 is able to rest without interruption and mattress 16 is eventually rid of bed bugs 15.

[0042] Mattress package 12 includes a bag 18 formed to include a mouth 20 opening into mattress-receiving space 14 formed in bag 18 and a closure 22 as shown in Figs. 1 and 4. Mattress 16 is placed in mattress-receiving space 14 through open mouth 20. Closure 22 is coupled to bag 18 to selectively close mouth 20 to cause mattress 16 to be enclosed in mattress-receiving space 14. Once bed bugs 15 have been killed off, the person 13 may remove mattress 16 from mattress package 12 or leave mattress 16 in mattress-receiving space 14 to block staining of mattress 16.

[0043] Bag 18 of mattress package 12 is made from a sheet 24 as suggested in

Figs. 2 and 3. Sheet 24 is configured to provide means for transporting moisture 11 provided by person 13 resting on bedding arrangement 10 in an inbound direction 26 from person 13 into mattress-receiving space 14 when person 13 is resting on bedding arrangement 10 and in an outward direction 28 from mattress-receiving space 14 to atmosphere 30 surrounding bedding arrangement 10 when person 13 is not resting on bedding arrangement 10 without allowing passage of needle-like mouth parts of bed bugs 15 through sheet 24 so that person 13 is not bitten by bed bugs 15 located in mattress-receiving space 14 and the comfort of person 13 resting on bedding

arrangement 10 is maximized as a result of moisture 11 being transported away from person 13 and bed bugs 15 being blocked from biting person 13 as suggested in Figs. 1 and 2.

[0044] Sheet 24 includes an outer surface 32 and an inner surface 34. Outer surface 32 is arranged to face person 13 resting on bedding arrangement 10 as shown in Fig. 1. Inner surface 34 is arranged to face opposite outer surface 32 and define mattress-receiving space 14 as shown in Fig. 5. Sheet 24 transports moisture 11 provided by the person 13 from a zone 58 characterized by a higher concentration to a zone 60 characterized a relatively lower concentration. As a result, moisture 11 provided by the person 13 as the person sweats during sleep collects on outer surface 32. This higher concentration of moisture 11 is then transported from outer surface 32 through sheet 24 to inner surface 34 where moisture 11 is released into mattress-receiving space 14 while the person 13 remains resting on bedding arrangement 10.

[0045] Sheet 24 includes, for example, from outside to inside, an outer comfort layer 240, an insect-barrier layer 24B, and an inner comfort layer 241 as shown in Fig. 2. Outer comfort layer 240 is configured to provide outer surface 32. Inner comfort layer 241 is configured to provide inner surface 34. Insect-barrier layer 24B is arranged to lie between and interconnect inner and outer comfort layers 241, 240. Insect-barrier layer 24B provides the means for blocking biting of bed bugs 15 as a result of the material being substantially continuous and imperforate while still having the ability to transport moisture 11 from zones of higher concentration to zones of relatively lower

concentration.

[0046] Sheet 24 forms a bag blank 36 as shown in Fig. 3. Bag blank 36 includes a top panel 36T, a bottom panel 36B, and an end wall 36E. During a bag-forming process, top panel 36T is folded about a first fold line 41 positioned to lie between top panel 36T and end wall 36E. End wall 36E is then folded about a second fold 42 positioned to lie about midway between top and bottom panels 36T, 36E. End wall 36E and top panel 36T are then folded about a third fold line 43 to cause top panel 36T to lie in confronting relation with bottom panel 36B. Perimeter edges of the top and bottom panels 36T, 36B are then coupled together to establish bag 18 as shown in Fig. 4. In on illustrative example, the perimeter edges are coupled together by heat to establish a heat seal. In another example, the perimeter edges may be coupled together by adhesive or any other suitable alternative.

[0047] Mattress 16 includes a top surface 16T, a bottom surface 16B, a first side wall 161, a second side wall 162, a first end wall 163, and a second end wall 164 as shown in Fig. 6. Top surface 16T is arranged to face toward the person 13 and inner top panel 36T of sheet 24. Bottom surface 16B is arranged to face opposite top surface 16T toward bottom panel 36B of sheet 24. First side wall 161 extends between and interconnects top and bottom surfaces 16T, 16B as shown in Fig. 6. Second side wall 162 is spaced apart from first side wall 161 and is arranged to extend between and interconnect top and bottom surfaces 16T, 16B. First end wall 163 is arranged to extend between and interconnect top and bottom surfaces 16T, 16B and first and second side walls 161, 612 at a head end 54. Second end wall 164 is spaced apart from and arranged to extend between and interconnect top and bottom surfaces 16T, 16B and first and second side walls 161, 612 at a foot end 56.

[0048] Closure 22 included in mattress package 12 is coupled to bag 18 to close open mouth 20 selectively as suggested in Figs. 7 and 8. Closure 22 includes a first closure strip 40, a second closure strip 44, and a closure mechanism 46 as shown in Figs. 3 and 4. First closure strip 40 is coupled to bottom panel 36B and is illustratively a zipper track made of plastics material. Second closure strip 44 is couple to top panel 36T and is illustratively a zipper track made of plastics material. Each closure strip 40, 44 is coupled to associated panel 36B, 36T by heat to establish a heat seal. However, any other suitable alternative may be used such as adhesive.

[0049] Closure mechanism 46 is coupled to both first and second closure strips

40, 44 to cause the closure strips 40, 44 to couple to one another as closure mechanism 46 is moved laterally in a sideways direction 45 across both closure strips 40, 44 as shown in detail in Figs. 4 and 6. In the illustrative example of Figs. 7 and 8, closure mechanism 46 is a zipper head.

[0050] Once mattress 16 is located in mattress-receiving space 14 and the person

13 is resting on bedding arrangement 10, mattress package 12 is configured to allow moisture 11 to move away from person 13 and into mattress-receiving space 14 at a moisture transfer rate. In one example, the moisture transfer rate is at least 200 grams per square meter per 24 hours. In another example, the moisture transfer rate is at least 1,000 grams per square meter per 24 hours.

[0051] Mattress package 12, also called encasement 12, may also have a basis weight of less than about 200 grams square meter. In another example, mattress package 12 may have a basis weight of less than about 150 grams per square meter. In still yet another example, mattress package 12 may have a basis weight of less than about 120 grams per square meter. As a thickness of sheet 24 decreases, mattress package 12 feels softer and conforms more easily to mattress 16.

[0052] As suggested in Figs. 6-8, closure mechanism 46 closes mouth 20 opening into bag 18. Bag 18 includes, for example, an outer pouch 48, a middle pouch 50, and an inner pouch 52 as suggested in Fig. 4. Inner pouch 52 is configured to provide inner comfort layer 241. Middle pouch 50 is configured to provide insect-barrier layer 24B. Outer pouch 48 is configured to provide outer comfort layer 240. Middle pouch 50 is located between inner and outer pouches 48, 52. Middle pouch 50 is relatively larger than inner pouch 52 so as to surround and enclose inner pouch 52. Outer pouch 48 is relatively larger than middle pouch 50 so as to surround and enclose middle pouch 50 and inner pouch 52.

[0053] Outer comfort layer 240 is illustratively a breathable nonwoven material which has the ability to transfer moisture 11 in the form of water vapor through the material at a rate of at least about 50 grams per square meter per 24 hours. The nonwoven material is a material having a structure of individual fibers, filaments, or threads which are interlaid in an unidentifiable pattern. In another example, outer comfort layer 240 is a 30 grams per square meter spunlace blend of polyester and polypropylene. Outer comfort layer 240 may also be provided with or without a pattern of apertures formed in the layer.

[0054] In another example, outer comfort layer 240 may be a nonwoven material having a 44 grams per square meter basis weight. The nonwoven material may be a KAZZMERE™ nonwoven which is a softened Spunbond-Metlblown-Spunbond (SMS) polypropylene nonwoven material. In still yet another example, outer comfort layer 240 may be a nonwoven SMS material having a basis weight of about fifteen grams per square meter.

[0055] Insect-barrier layer 24B is illustratively made from a blend of about 30% breathable copolyamide resin and about 70% nonbreathable resin. The breathable copolyamide may be PEBAX® 1074 and the nonbreathable resin may be LOTRYL® 28MA07. In another example, the insect-barrier layer 24B is made of a blend of 70% PEBAX® 1074 and 30% LOTRYL® 28MA07. In yet another illustrative example, insect-barrier layer 24B may be a coextrusion of 7% ARNITEL® EM400 inner skin, 86% ANRITEL® VT3108, and 7% ARNITEL® EM400 outer skin.

[0056] Inner comfort layer 241 is illustratively a breathable nonwoven material which has the ability to transfer moisture 11 is the form of water vapor through the material at a rate of at least about 50 grams per square meter per 24 hours. In another example, inner comfort layer 241 is a 30 gram per square meter spunlace blend of polyester and polypropylene. Inner comfort layer 241 may also be provided with or without a pattern of apertures formed in the.

[0057] In another example, inner comfort layer 241 may be a nonwoven material having a 44 grams per square meter basis weight. The nonwoven material may be a KAZZMERE™ nonwoven which is a softened Spunbond-Metlblown-Spunbond (SMS) polypropylene nonwoven material. In still yet another example, inner comfort layer 241 may be a nonwoven SMS material having a basis weight of about fifteen grams per square meter.

[0058] Together, outer comfort layer 240, insect-barrier layer 24B, and inner comfort layer 241 may be formed through an extrusion lamination process. In this example, outer comfort layer 240 is unwound along with inner comfort layer 241. Inner and outer comfort layers 241, 240 are then laminated together by insect-barrier layer 24B which is applied via extrusion of the molten material between inner and outer comfort layers 241, 240. As a result, sheet 24 is formed and wound for further processing such as the exemplary bag-forming process discussed previously. First sheet 24 is formed without adhesive between layers 240, 24B, and 241.

[0059] Bag 18, in one illustrative example, includes inner and outer comfort layers 241, 240 made from a 30 grams per square meter spunlace blend of polyethylene and polypropylene. Bag 18 further includes insect-barrier layer 24B made from a blend of 30% PEBAX® 1074 and 70% LOTRYL® 28MA07. As a result, bag 18 has a moisture transfer rate of about 681 grams per square meter per 24 hours at 37.8 degrees Celsius and 100% relative humidity.

[0060] In another example, a mattress that is not infested with bed bugs may be placed in mattress-receiving space 14 of mattress package 12 to protect the mattress from a bed-bug infestation. In this example, beg bugs may not move into mattress-receiving space 14 after mouth 20 has been closed by closure 22. As a result, mattress package 12 may be used to block infestation of the mattress as well as rid the mattress from infestation. In addition, a bedding package in accordance with the present disclosure may be sized and configured to receive mattress 16, a box spring, or both a mattress and box spring in mattress-receiving space 14.

[0061] Another embodiment of bedding arrangement 110 is shown, for example in Figs. 9, 12, and 13. Bedding arrangement 110, in accordance with the present disclosure, includes a mattress package 112 formed to include a mattress-receiving space 114 and a mattress 16 arranged to lie in the mattress-receiving space 114. In one illustrative example, mattress 16 may become infested with bed bugs 15 or other insects which may harm a person resting on mattress 16 or disrupt the person's sleep. Placing the infested mattress 16 and bed bugs 15 in mattress-receiving space 114 and closing the mattress package 112 so that bed bugs 15 are trapped in mattress-receiving space 114 causes the person 13 to be isolated from bed bugs 15 and bed bugs 15 to eventually die from starvation. As a result, the person 13 is able to rest without interruption from bed bugs 15 and mattress 16 is eventually rid of bed bugs 15.

[0062] Mattress package 112 includes a bag 118 formed to include a mouth 120 opening into mattress-receiving space 114 formed in bag 118 and a closure 122 as shown in Figs. 9 and 12. Mattress 16 is placed in mattress-receiving space 114 through open mouth 120. Closure 122 is coupled to bag 118 to permanently close mouth 120 to cause mattress 16 to be enclosed in mattress-receiving space 114. Once closure 122 closes open mouth 120, closure 120 cannot be opened. Mattress package 112 is a single-use mattress package 112. Single-use mattress package 112 is not intended to be separated from mattress 16 and reinstalled on another mattress 16 at a later time. As a result, mattress package 112 is considered to be disposable and not suitable for washing and reuse.

[0063] Bag 118 of mattress package 112 is made from a first sheet 124 and a second sheet 125 as suggested in Figs. 10 and 11. First sheet 124 is configured to underlie and support person 13 as suggested in Fig. 9. Second sheet 125 is coupled to first sheet 124 and cooperates with first sheet 124 to surround and encase mattress 16 as shown in Fig. 13.

[0064] First sheet 124 is configured to provide means for transporting moisture

11 provided by person 13 resting on bedding arrangement 110 in inbound direction 26 from person 13 into mattress-receiving space 114 when person 13 is resting on bedding arrangement 110 and in outward direction 28 from mattress-receiving space 114 to atmosphere 30 surrounding bedding arrangement 110 when person 13 is not resting on bedding arrangement 110. Both first sheet 124 and second sheet 125 cooperate to provide means for blocking passage of needle-like mouth parts of bed bugs 15 through sheets 124, 125 so that person 13 is not bitten by bed bugs 15 located in mattress- receiving space 114 and the comfort of person 13 resting on bedding arrangement 110 is maximized as a result of moisture 11 being transported away from person 13 and bed bugs 15 being blocked from biting person 13 as suggested in Figs. 9 and 10.

[0065] First sheet 124 includes an outer surface 132 and an inner surface 134.

Outer surface 132 is arranged to face person 13 resting on bedding arrangement 110 as shown in Fig. 9. Inner surface 134 is arranged to face opposite outer surface 132 toward mattress 16 and define mattress-receiving space 114 as shown in Fig. 13. Sheet 124 transports moisture 11 provided by the person 13 through first sheet 124 from higher concentration to relatively lower concentration. As a result, moisture 11 provided by the sweating person 13 collects on outer surface 132. This higher concentration of moisture 11 is then transported from outer surface 132 through first sheet 124 to inner surface 134 where moisture 11 is released into mattress-receiving space 114 while person 13 remains resting on bedding arrangement 110.

[0066] First sheet 124 includes, for example, from outside to inside, outer comfort layer 240, insect-barrier layer 24B, and inner comfort layer 241 as shown in Fig. 10. Outer comfort layer 240 is configured to provide outer surface 132. Inner comfort layer 241 is configured to provide inner surface 134. Insect-barrier layer 24B is arranged to lie between and interconnect inner and outer comfort layers 240, 241. Insect-barrier layer 24B provides the means for blocking biting of bed bugs 15 as a result of the material being substantially continuous and imperforate while still having the ability to transport moisture 11 from zones of higher concentration to zones of relatively lower concentration.

[0067] Second sheet 125 includes, for example, from outside to inside, an outer insect-barrier layer 1250, a core insect-barrier layer 125C, and an inner insect-barrier layer 1251 as shown in Fig. 10. Outer insect-barrier layer 1250 is configured to provide an outer surface 133. Outer surface 133 is arranged to face away from person 13, mattress-receiving space 114, and mattress 16. Inner insect-barrier layer 1251 is configured to provide an inner surface 135. Inner surface 135 is arranged to face toward mattress 16 and mattress-receiving space 114 as shown in Fig. 13. Inner surface 134 of first sheet 124 and inner surface 135 of second sheet 125 cooperate to define mattress- receiving space 114 therebetween.

[0068] First sheet 124 is used to form a top panel 136T. Second sheet 125 is used to form a bottom panel 136B, a first side wall 1361, and a second side wall 1362 as shown in Fig. 11. During a bag-forming process, first side wall 1361 is folded about a first fold line 141 and coupled to top panel 136T and bottom panel 136B to extend therebetween. Second side wall 1362 is folded about a second fold line 142 and coupled to top panel 136T and bottom panel 136B to extend therebetween in spaced-apart relation to first side wall 1361 as suggested in Fig. 11. In one example, side walls 1361, 1362 are coupled to top and bottom panels 136T, 136B by heat to form heat seals along perimeter edges of top and bottom panels 136T, 136B. Top and bottom panels 136T, 136B are then coupled together, by heat for example, along a head end 54 as shown in Fig. 12. In another example, coupling may achieved by adhesive or any other suitable alternative. [0069] A closure 122 included in mattress package 112 is coupled to bag 118 to close open mouth 120 selectively as suggested in Figs. 15 and 16. Closure 122 includes a first closure strip 140 and a second closure strip 144 as shown in Figs. 11, 12, 15, and 16. First closure strip 140 is coupled to bottom panel 136B and is illustratively a press- fit track made of plastics material. Second closure strip 144 is couple to top panel 136T and is illustratively a press-fit track made of plastics material. Each closure strip 140, 144 is coupled to associated panel 136B, 136T and side walls 1361, 1362 by heat to establish a heat seal. However, any other suitable alternative may be used such as adhesive.

[0070] First and second closure strips 140, 144 are coupled together to close open mouth 120 by aligning closure strips 140, 144 and pressing together as shown in Fig. 15. In an example, a user places a forefinger 13F on second closure strip 144 and a thumb 13T on first closure strip 140 and presses then together. As a result, first and second closure strips 140 mate with one another. User then slides forefinger 13F and thumb 13T together laterally in sideways direction 45 to close open mouth 120 as suggested in Fig. 15 and shown in Fig. 16. Once closure strips 140, 144 mate together, they cannot be separated without damaging closure 122 or bag 118 that would then destroy the ability to block biting and movement of bed bugs.

[0071] Once mattress 16 is located in mattress-receiving space 114 and the person 13 is resting on bedding arrangement 110, mattress package 112 is configured to allow moisture 11 to move away from person 13 and into mattress-receiving space 114 at a moisture transfer rate. In one example, the moisture transfer rate is at least 200 grams per square meter per 24 hours. In another example, the moisture transfer rate is at least 1,000 grams per square meter per 24 hours.

[0072] Mattress package 112 may also have a basis weight of less than about 200 grams square meter. In another example, mattress package 112 may have a basis weight of less than about 150 grams per square meter. In still yet another example, mattress package 112 may have a basis weight of less than about 120 grams per square meter. As a thickness of sheets 124, 125 decreases, mattress package 112 feels softer and conforms more easily to mattress 16.

[0073] As suggested in Figs. 10 and 13, closure 122 closes mouth 20 opening into bag 118. Bag 118 includes, for example, an outer pouch 148, a middle pouch 150, and an inner pouch 152 as suggested in Fig. 12. Inner pouch 152 is configured to provide inner comfort layer 241 and inner insect-barrier layer 1251. Middle pouch 150 is configured to provide insect-barrier layer 24B and core insect-barrier layer 125C. Outer pouch 148 is configured to provide outer comfort layer 240 and outer insect-barrier layer 1250. Middle pouch 150 is located between inner and outer pouches 148, 152. Middle pouch 150 is relatively larger than inner pouch 152 so as to surround and enclose inner pouch 152. Outer pouch 148 is relatively larger than middle pouch 150 so as to surround and enclose middle pouch 150 and inner pouch 152.

[0074] Outer comfort layer 240 is illustratively a breathable nonwoven material which has the ability to transfer moisture 11 is the form of water vapor through the material at a rate of at least about 50 grams per square meter per 24 hours. The nonwoven material is a material having a structure of individual fibers, filaments, or threads which are interlaid in an unidentifiable patter. In another example, outer comfort layer 240 is a 30 grams per square meter spunlace blend of polyester and polypropylene. Outer comfort layer 240 may also be provided with or without a pattern of apertures formed in the layer.

[0075] In another example, outer comfort layer 240 may be a nonwoven material having a 44 grams per meter squared basis weight.

In still yet another example, outer comfort layer 240 may be a nonwoven SMS material having a basis weight of about fifteen grams per square meter.

[0076] Insect-barrier layer 24B is illustratively made from a blend of about 30% breathable copolyamide resin and about 70% nonbreathable resin. The breathable copolyamide may be PEBAX® 1074 and the nonbreathable resin may be LOTRYL® 28MA07. In another example, the insect-barrier layer 24B is made of a blend of 70% PEBAX® 1074 and 30% LOTRYL® 28MA07. In yet another illustrative example, insect-barrier layer 24B may be a coextrusion of 7% ARNITEL® EM400 inner skin, 86% ANRITEL® VT3108, and 7% ARNITEL® EM400 outer skin.

[0077] Inner comfort layer 241 is illustratively a breathable nonwoven material which has the ability to transfer moisture 11 is the form of water vapor through the material at a rate of at least about 50 grams per square meter per 24 hours. In another example, inner comfort layer 241 is a 30 grams per square meter spunlace blend of polyester and polypropylene. Inner comfort layer 241 may also be provided with or without a pattern of apertures formed in the layer.

[0078] In another example, inner comfort layer 241 may be a nonwoven material having a 44 grams per meter squared basis weight. The nonwoven material may be a KAZZMERE™ nonwoven which is a softened Spunbond-Metlblown-Spunbond (SMS) polypropylene nonwoven material. In still yet another example, inner comfort layer 241 may be a nonwoven SMS material having a basis weight of about fifteen grams per square meter.

[0079] Bag 118 in one illustrative example includes inner and outer comfort layers 241, 240 made from a 30 grams per square meter spunlace blend of polyethylene and polypropylene. Bag 118 further includes insect-barrier layer 24B made from a blend of 30% PEBAX® 1074 and 70% LOTRYL® 28MA07. As a result, bag 118 has a moisture transfer rate of about 681 grams per square meter per 24 hours at 37.8 degrees Celsius and 100% relative humidity.

[0080] Outer insect-barrier layer 1250 is illustratively a polypropylene film. In one example, the polypropylene film is made from BRASKEM® HI 10.02N. In another example, the polypropylene film is made from TOTAL 8473.

[0081] Inner insect-barrier layer 1251 is illustratively a polypropylene film. In one example, the polypropylene film is made from BRASKEM® HI 10.02N. In another example, the polypropylene film is made from TOTAL 8473.

[0082] Core insect-barrier layer 125C is made from a blend of resins at various amounts. In one example, the blend includes about 70% of a first type of linear low density polyethylene, about 25% low density polyethylene, and about 5% of a second type of linear low density polyethylene. In one illustrative example, the first type of linear low density polyethylene is DOW® 2056G. The second type of linear low density polyethylene is AMPACET® 111017P. The low density polyethylene is, for example, CHEVRON® 5754.

[0083] Another embodiment of bedding arrangement 210 is shown, for example, in Figs. 17, 18, 20, and 22. Bedding arrangement 210, in accordance with the present disclosure, includes a mattress package 212 formed to include a mattress-receiving space 214 and a mattress 16 arranged to lie in mattress-receiving space 214. Mattress package 212 includes a bag 218 formed to include a mouth 220 opening into mattress-receiving space 214 formed in bag 218 and a closure 222 as shown in Figs. 17 and 20. Mattress 16 is placed in mattress-receiving space 214 through open mouth 220. Closure 222 is coupled to bag 218 to selectively close mouth 220 to cause mattress 16 to be enclosed in mattress-receiving space 214.

[0084] Bag 218 of mattress package 212 is made from a sheet 224 as suggested in Figs. 18 and 19. Sheet 224 is configured to provide means for transporting moisture 11 provided by person 13 resting on bedding arrangement 210 in inbound direction 26 from person 13 into mattress-receiving space 214 when person 13 is resting on bedding arrangement 10 and in outward direction 28 from mattress-receiving space 214 to atmosphere 30 surrounding bedding arrangement 210 when person 13 is not resting on bedding arrangement 210 without allowing passage of needle-like mouth parts of bed bugs 15 through sheet 224 so that person 13 is not bitten by bed bugs 15 located in mattress-receiving space 214 and comfort of person 13 resting on bedding arrangement 210 is maximized as a result of moisture 11 being transported away from person 13 and bed bugs 15 being blocked from biting person 13 as suggested in Figs. 17 and 18.

[0085] Sheet 224 includes an outer surface 232 and an inner surface 234. Outer surface 232 is arranged to face person 13 resting on bedding arrangement 210 as shown in Fig. 17. Inner surface 234 is arranged to face opposite outer surface 232 and define mattress-receiving space 214 as shown in Fig. 21. Sheet 224 transports moisture 11 provided by the person 13 through sheet 224 from higher concentration to relatively lower concentration. As a result, moisture 11 provided by the person 13 as the person 13 sweats during sleep collects on outer surface 232. This high concentration of moisture 11 is then transported from outer surface 232 through sheet 224 to inner surface 234 where the moisture is released into mattress-receiving space 214 while the person 13 remains resting on bedding arrangement 210.

[0086] Sheet 224 includes, for example, from outside to inside, outer comfort layer 240, insect-barrier layer 24B, and inner comfort layer 241 as shown in Fig. 18. Outer comfort layer 240 is configured to provide outer surface 232. Inner comfort layer 241 is configured to provide inner surface 234. Insect-barrier layer 24B is arranged to lie between and interconnect inner and outer comfort layers 241, 240. Insect-barrier layer 24B provides the means for blocking biting of bed bugs 15 as a result of the material being substantially continuous and imperforate while still having the ability to transport moisture 11 from zones of higher concentration to zones of relatively lower

concentration. [0087] Sheet 224 forms a bag blank 236 as shown in Fig. 19. Bag blank 236 includes a top panel 236T, a bottom panel 236B, a bottom closure flap 2361, and a top closure flap 2362. Bottom closure flap 2361 is coupled to bottom panel 236B. Top closure flap 2362 is coupled to top panel 236T. During a bag-forming process, top panel 236T is folded about a first fold line 241 and coupled to bottom panel 236B. In one example, top and bottom panel 236T, 236B are coupled to one another around their side edges, and head end edge opposite mouth 220 by heat to form associated heat seals. In another example, coupling may achieved by adhesive or any other suitable alternative.

[0088] A closure 222 included in mattress package 212 is coupled to bag 218 to close open mouth 220 selectively as suggested in Figs. 23 and 24. Closure 222 includes a first closure strip 240 coupled to bottom closure flap 2361 and a second closure strip 244 coupled to top closure flap 2362 as shown in Figs. 19, 20, 23, and 24. First closure strip 240 is coupled to bottom closure flap 2361 and is illustratively a strip of double- sided tape 240A with a release liner 240B that is removed prior to enclosing mattress 16 in mattress-receiving space 214. Second closure strip 244 is coupled to top closure flap 2362 and is illustratively a strip of double-sided tape 244A with a release liner 244B that is removed prior to enclosing mattress 16 in mattress-receiving space 214 as shown in Fig. 22.

[0089] As shown, for example in Fig. 22, bottom closure flap 2361 is first coupled to mattress 16 by removing release liner 240B and pressing double-sided tape 240A against mattress 16 as suggested in Fig. 22 and shown in Fig. 23. Top closure flap 2362 is then coupled to bottom closure flap 2361 by removing release line 244B and pressing double-sided tape 244A against bottom closure flap 2361 as shown in

Figs. 22-24.

[0090] Once mattress 16 is located in mattress-receiving space 214 and the person 13 is resting on bedding arrangement 210, mattress package 212 is configured to allow moisture 11 to move away from person 13 and into mattress-receiving space 214 at a moisture transfer rate. In one example, the moisture transfer rate is at least 200 grams per square meter per 24 hours. In another example, the moisture transfer rate is at least 1,000 grams per square meter per 24 hours.

[0091] Mattress package 212 may also have a basis weight of less than about 200 grams square meter. In another example, mattress package 212 may have a basis weight of less than about 150 grams per square meter. In still yet another example, mattress package 212 may have a basis weight of less than about 120 grams per square meter. As a thickness of sheets 224, 225 decreases, mattress package 212 feels softer and conforms more easily to mattress 16.

[0092] As suggested in Figs. 20 and 21, closure 222 closes mouth 220 opening into bag 218. Bag 218 includes, for example, an outer pouch 248, a middle pouch 250, and an inner pouch 252 as suggested in Fig. 20. Inner pouch 252 is configured to provide inner comfort layer 241 and inner insect-barrier layer 2251. Middle pouch 250 is configured to provide insect-barrier layer 24B and core insect-barrier layer 225C. Outer pouch 248 is configured to provide outer comfort layer 240 and outer insect-barrier layer 2250. Middle pouch 250 is located between inner and outer pouches 248, 252. Middle pouch 250 is relatively larger than inner pouch 252 so as to surround and enclose inner pouch 252. Outer pouch 248 is relatively larger than middle pouch 250 so as to surround and enclose middle pouch 250 and inner pouch 252.

[0093] Outer comfort layer 240 is illustratively a breathable nonwoven material which has the ability to transfer moisture 11 is the form of water vapor through the material at a rate of at least about 50 grams per square meter per 24 hours. The nonwoven material is a material having a structure of individual fibers, filaments, or threads which are interlaid in an unidentifiable patter. In another example, outer comfort layer 240 is a 30 grams per square meter spunlace blend of polyester and polypropylene. Outer comfort layer 240 may also be provided with a pattern of apertures formed in the layer so as to maximize breathability of outer comfort layer 240.

[0094] In another example, outer comfort layer 240 may be a nonwoven material having a 44 grams per square meter basis weight. The nonwoven material may be a KAZZMERE™ nonwoven which is a softened Spunbond-Metlblown-Spunbond (SMS) polypropylene nonwoven material. In still yet another example, outer comfort layer 240 may be a nonwoven SMS material having a basis weight of about fifteen grams per square meter.

[0095] Insect-barrier layer 24B is illustratively made from a blend of about 30% breathable copolyamide resin and about 70% nonbreathable resin. The breathable copolyamide resin may be PEBAX® 1074 and the nonbreathable resin may be

LOTRYL® 28MA07. In another example, the insect-barrier layer 24B is made of a blend of 70% PEBAX® 1074 and 30% LOTRYL® 28MA07. In yet another illustrative example, insect-barrier layer 24B may be a coextrusion of 7% ARNITEL® EM400 inner skin, 86% ANRITEL® VT3108, and 7% ARNITEL® EM400 outer skin.

[0096] Inner comfort layer 241 is illustratively a breathable nonwoven material which has the ability to transfer moisture 11 in the form of water vapor through the material at a rate of at least about 50 grams per square meter per 24 hours. In another example, inner comfort layer 241 is a 30 grams per square meter spunlace blend of polyester and polypropylene. Inner comfort layer 241 may also be provided with a pattern of apertures formed in the layer so as to maximize breathability of inner comfort layer 241.

[0097] In another example, inner comfort layer 241 may be a nonwoven material having a 44 grams per meter squared basis weight. The nonwoven material may be a KAZZMERE™ nonwoven which is a softened Spunbond-Metlblown-Spunbond (SMS) polypropylene nonwoven material. In still yet another example, inner comfort layer 241 may be a nonwoven SMS material having a basis weight of about fifteen grams per square meter.

[0098] Bag 218 in one illustrative example includes inner and outer comfort layers 241, 240 made from a 30 gram per square meter spunlace blend of polyester and polypropylene. Bag 218 further includes insect-barrier layer 24B made from a blend of 30% PEBAX® 1074 and 70% LOTRYL® 28MA07. As a result, bag 218 has a moisture transfer rate of about 681 grams per square meter per 24 hours at about 37.8 degrees Celsius at about 100% relative humidity.

[0099] Outer insect-barrier layer 2250 is illustratively a polypropylene film. In one example, the polypropylene film is made from BRASKEM® HI 10.02N. In another example, the polypropylene film is made from TOTAL 8473.

[00100] Inner insect-barrier layer 2251 is illustratively a polypropylene film. In one example, the polypropylene film is made from BRASKEM® HI 10.02N. In another example, the polypropylene film is made from TOTAL 8473.

[00101] Core insect-barrier layer 225C is made from a blend of resins at various amounts. In one example, the blend includes about 70% of a first type of linear low density polyethylene, about 25% low density polyethylene, and about 5% of a second type of linear low density polyethylene. In one illustrative example, the first type of linear low density polyethylene is DOW® 2056G. The second type of linear low density polyethylene is AMPACET® 111017P. The low density polyethylene is, for example, CHEVRON® 5754.

[00102] Another embodiment of bedding arrangement 310 is shown, for example, in Figs. 25 and 28-30. Bedding arrangement 310, in accordance with the present disclosure, includes a mattress package 312 formed to include a mattress-receiving space 314 and a mattress 16 arranged to lie in mattress-receiving space 314. Mattress package 312 includes a bag 318 formed to include a mouth 320 opening into mattress-receiving space 314 formed in bag 318 and closure 22 as shown in Figs. 25 and 28. Mattress 16 is placed in mattress-receiving space 314 through open mouth 320. Closure 22 is coupled to bag 318 to selectively close mouth 320 to cause mattress 16 to be enclosed in mattress-receiving space 314.

[00103] Bag 318 of mattress package 312 is made from sheet 24 as suggested in

Figs. 26 and 27. Sheet 24 is configured to provide means for transporting moisture 11 provided by person 13 resting on bedding arrangement 310 in inbound direction 26 from person 13 into mattress-receiving space 314 when person 13 is resting on bedding arrangement 310 and in outward direction 28 from mattress-receiving space 314 to atmosphere 30 surrounding bedding arrangement 310 when person 13 is not resting on bedding arrangement 310.

[00104] Sheet 24 forms bag blank 36 as shown in Fig. 27. Bag blank 36 includes top panel 36T, bottom panel 36B, and end wall 36E. During a bag-forming process, top panel 36T is folded about first fold line 41 positioned to lie between top panel 36T and end wall 36E. End wall 36E is then folded about second fold 42 positioned to lie about midway between top and bottom panels 36T, 36B. End wall 36E and top panel 36T are then folded about third fold line 43 to cause top panel 36T to lie in confronting relation with bottom panel 36B. Perimeter edges 317 of the top and bottom panels 36T, 36B are then coupled together and the resulting sack is turned inside out so that the perimeter edges lie in mattress-receiving space 314 to establish bag 318 as shown in Fig. 29.

Perimeter edges 317 are arranged to extend toward mattress 16 as shown in Fig. 29.

[00105] In comparison, the perimeter edges of bag 18 are positioned to lie outside mattress-receiving space 14 and arranged to extend away from mattress 16. Bag 318 is configured to provide a shape which is more similar to mattress 16 so that any sheets folded or placed on bedding arrangement 310 will conceal the presence of mattress package 312. [00106] In another illustrative embodiment, a bedding arrangement may further include an air passage valve. For example, an air passage valve may be in one of the sheets and be configured to communicate air in the mattress-receiving space to the atmosphere surrounding the bedding arrangement. In another example, the air passage vale may be used to communicate air from atmosphere surrounding the bedding arrangement into the mattress-receiving space. Such an air passage valve may be a oneway or a two-way valve. In one example, the air passage valve would not allow bed bugs to pass from the mattress-receiving space to outside the mattress package.

[00107] In another embodiment, a mattress package may disposable and temporary in nature. As an example, a traveler may place a hotel mattress in the mattress package to isolate the traveler from any bugs, stains, or other contaminants included in the hotel mattress. In addition, a person may place a mattress in the mattress package where relief or control of bed bugs may not be possible (e.g., multifamily apartments or dorms) or may be uncertain to the person (e.g., hotels).
