BEDDING COVER FOR PREVENTING PEST ESCAPEMENT OR INFESTATION VIA A ZIPPER OPENING

Abstract

A bedding cover made of pest-impermeable fabric provides a zippered opening for insertion of mattresses, pillows, upholstered cushions and other bedding. At the end of the zipper track, where there may be a small opening when closed, a flap is attached to a plastic collar, which is stitched to the fabric cover at and around the end of the zipper track. The flap is adapted to fold over the end when the zipper is closed, providing a seal that prevents pests, such as bed bugs, from escaping the bedding cover or infesting the bedding.

Description

This application claims the benefit of U.S. Provisional Patent Application No. 61/734,121, filed on Dec. 6, 2012, which is incorporated by referenced herein in its entirety.

The invention relates to an apparatus for preventing bed bugs and other pests from infesting bedding or from escaping the bedding if an infestation has previously occurred. Specifically, the invention relates to a collar and flap structure on a bedding cover that seals the cover, preventing pest escapement or infestation, but that can be optionally opened and resealed to allow insertion and removal of bedding.

BACKGROUND

Pest invasion is a problem faced by both the hospitality industry and individuals. Fleas, chicken mites, dust mites, ticks, and bed bugs are all common invaders, making their homes in beds and feeding parasitically off of human blood and skin cells.

Bed bugs, or Cimex lectularis, have become a particularly prevalent invader in the last decade because of the wide use of insecticide bait and increased global travel and commerce. Because bed bugs feed on human blood, rather than bait, common insecticidal treatments do not affect them. Bed bug populations have exploded because eggs, young, and adult bed bugs are readily transported in luggage, clothing and bedding, and because bed bugs can infest airplanes, ships, trains, and buses. Bed bugs are most frequently found in dwellings with a high rate of occupant turnover, such as hotels, motels, hostels, dormitories, shelters, apartment complexes, tenements, and prisons. They, as well as other pests, are nocturnal blood-feeders that bite victims while they sleep.

To protect travelers and individuals in their own homes, strategies have emerged to kill bed bugs by encasing them inside an infested mattress and starving them. Efforts have focused primarily on bed bud infestations, and primarily on mattress encasements. These strategies may problematic for the hospitality industry, however, because the existence of even dead pests inside a mattress may be viewed as unhygienic. In addition, the encasement may not provide a completely pest-impermeable seal, particularly where the encasement has a zipper or other closure that leaves a small opening, or where use of, or movement on, the encased mattress causes a zipper to slide open.

Accordingly, there exists a need to prevent pest infestation of various types of bedding, and their escapement from encasement systems.

SUMMARY

It is therefore an object of the invention to provide a bedding cover structure that prevents pests from escaping an encasement system through a zipper opening or other imperfect closure.

It is another object of the invention to provide a method of sealing, and optionally opening and resealing, bedding within a bedding cover such that pests are prevented from entering or exiting the cover through a zipper opening or other imperfect closure.

These and other objects of the invention are achieved in a bedding cover having a zipper opening for receiving bedding. A collar and flap are disposed at the zipper end of the cover in order to create a pest-impermeable seal, capable of optionally opening and resealing, over any small opening that may form at the zipper end.

In addition, objects of the invention are achieved in a method for sealing, and optionally opening and resealing, bedding within a bedding cover structure.

In one example a bedding cover for preventing pest escapement or infestation comprises a bedding cover comprising an opening and a zipper that includes a zipper head and opposing zipper tracks surrounding the perimeter of the opening. The zipper comprises an open position and a closed position. The bedding cover further includes an end location where the zipper head is positioned when the zipper is in the closed position. The bedding cover also includes a closure assembly including a collar and a flap. The collar is mounted on the bedding cover and around and proximate the end location of the zipper. The flap is mounted on one side to the bedding cover proximate the collar and is adapted to cover the end location of the zipper. The collar and the flap comprise a sealing mechanism that attaches the flap to the collar and over the end location of the zipper. The flap may be mounted on one side to the collar. The flap and collar may comprise mating hook-and-loop fasteners on respective surfaces thereof for releasably sealing and unsealing the flap onto the collar and over the end location of the zipper. The flap may be coated with a releasable adhesive or with a pest repellant. The flap may also be coated alternatively with a permanent adhesive.

DETAILED DESCRIPTION

Referring to FIG. 1, a bedding cover 100 surrounds a conventional mattress 101. The bedding cover 100 may be constructed of a size and shape so as to completely surround the entire mattress. In other embodiments, the bedding cover may be constructed of a size and shape so as to surround two sides of a pillow or any bedding, mattresses, duvets, pillows, upholstered cushions and futons. Fabric of the bedding cover is woven, knitted, or nonwoven or otherwise engineered so as to be pest-impermeable, such that any pest capable of infesting bedding cannot pass through it. The bedding cover 100 may optionally have one or more textured sides to as to prevent use of, or movement on the bedding, from occurring. Optional textured sides may occur on the interior or the exterior of the bedding cover, but all bedding cover fabric is engineered so as to be pest-impermeable.

Referring to FIG. 1, an opening 102 is shown as being located at one end of the encasement/bedding cover 100 and extending far enough along one side of the encasement to allow a mattress 101 to be placed into and taken out of the encasement, and to thereby allow installation and occasional laundering of the encasement. In other embodiments, an opening may extend across any or all of the sides 103, 104, 105 of the encasement/bedding cover 100 such that any bedding may be placed into, and taken out of, the bedding cover.

Referring now to all of the figures, a conventional zipper may close the bedding cover opening 102 so as to completely surround the mattress 101 or other bedding inside. The zipper closure includes a zipper head 106 and a pair of zipper tracks 107, 108. The tracks are attached to the perimeter of the opening by stitching 109 that is sufficiently tight to prevent pests from passing across the stitching. The tracks 107, 108 are oriented in a confronting relationship, are zipped together in a conventional fashion, and have meshable, interlocking teeth that, when zipped, are sufficiently tight to prevent pests from passing to the other side. The zipper head 106 connects the two tracks 107, 108 and, when pulled towards an end location 110, causes the tracks 107, 108 to interlock. The opening 102 extends between the end location 110 and the zipper head 106. In other embodiments, the opening may be closed with any slide locking mechanism, such as a plastic zipper.

A closure assembly includes a collar 111 is disposed proximate the end location 110 and is attached to the surface of the bedding cover 100. The collar 111 may be attached by stitching 112 that is sufficiently tight to prevent pests from passing across the stitching, by an adhesive, or by any other equivalent means that does not impair the pest-impermeability of the bedding cover 100. The collar 111 may be made of plastic, hook-and-loop fasteners, or of any material that increases—relative to the efficacy of the bedding cover fabric—the ability of a flap 113 to adhere to it after being repeatedly attached and detached. In one embodiment, the collar 111 surrounds three sides of the end location 110 providing increased surface for a flap 113 to adhere to. In other embodiments, the collar may only surround two sides of the end location.

Referring to FIG. 2, the zipper head 106 is shown connected to the zipper tracks 107, 108 and disposed in a position near the end location 110. The end location 110 is where the zipper head 106 is stopped from farther movement along the zipper tracks 107, 108. Even when a zipper is fully closed, a small zipper opening 114 is formed in front of the zipper head 106 at the end location 110.

In FIG. 2, an embodiment of the closure assembly is shown with no flap attached, representing an optional embodiment in which the flap may be completely removed and replaced. For instance, the flap or patch may be used and then disposed of and a fresh flap used to cover the zipper opening. In FIG. 4, the embodiment of the closure assembly is shown with the flap 113 attached at one end 115, with the free end 116 adapted to extend for a distance along the zipper tracks 107, 108 and optionally adhere to the collar 111, creating a pest-impermeable seal over the zipper opening 114 at the end location 110. In other embodiments, the sealing mechanism including the flap 113 may attach to any portion of the collar 111, and may be attached permanently or removably, making complete replacement of the flap possible. The sealing mechanism including the flap 113 may be attached by stitching that is sufficiently tight to prevent pests from passing across the stitching, by permanent or releasable adhesive, or by any other equivalent means that does not impair the pest-impermeability of the bedding cover.

Referring to FIG. 3, the zipper head 106 is shown near the end location 110 between three sides of the collar 111. The flap 113 is attached to the collar 111 behind the zipper head 106 and sits in a raised position, capable of being folded down over the zipper head and end location 110, as seen in FIG. 6. The flap 113 may alternatively be mounted on the bedding cover proximate the end location. The flap 113 may be made of plastic, hook-and-loop fasteners, or of any material that is capable of carrying a substance that may removably seal or permanently seal to the collar 111.

In alternative embodiments, the flap 113 may be coated with a substance that, in addition to sealing the flap 113 to the collar 111, contains a pest repellant such as an insecticide. Still further alternatively, the flap 113 may be coated with a malleable and tacky adhesive that conforms to the surface of the zipper head 106 when sealed and traps or adheres to pests if they attempt to escape or enter the bedding cover 110.

The progression of FIG. 4, FIG. 5 and FIG. 6 demonstrate some steps of a method for creating a pest-impermeable seal around bedding with a bedding cover 100. After the bedding has been placed into the bedding cover 100, the zipper head 106 may be pulled completely towards the end location 110, thereby encasing the bedding, and the flap 113 may be folded over and attached to the collar 111 over the end location 110, thereby creating a pest-impermeable seal around the bedding.

Still further alternatively, the flap 113 may be coated with an adhesive and other composition that changes color or otherwise signals that a pest has come in contact with it. This could be a signal to a user to dispose of an infested mattress.

And finally, the flap 113 may be a simple label that offers a display surface for a marketing opportunity or brand logo, There may also be included product information or instructions.

While the invention has been described with reference to certain embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or materials to the teachings of the invention without departing from its scope. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed, but that the invention will include all embodiments falling within the scope of the appended claims.
