TECHNICAL FIELD
The subject matter described herein relates to mattress protectors. More particularly, the subject matter described herein relates to a mattress protector that is cost effective to manufacture and easy to change.
BACKGROUND
In today's markets, mattresses cost hundreds or even thousands of dollars and represent substantial investments for individuals and for the hospitality and healthcare industries. In the hospitality and healthcare industries, the cost of mattresses is magnified by the number of mattresses that can be present in a typical facility, such as a hotel or in-patient care facility. In light of the substantial investment made in mattresses, mattress protectors are used to prevent damage to mattresses. However, conventional mattress protectors are expensive to manufacture and/or difficult to change. For example, some existing mattress protectors require straps, Velcro® fasteners, or adhesive fasteners to be sewn into a protector sheet to hold the sheet securely to the mattress. Such features increase the cost of mattress protectors and make them difficult to manufacture.
Accordingly, in light of these difficulties, there exists a need for an improved mattress protector that is cost effective to manufacture and easy to change.
SUMMARY
According to one aspect of the subject matter described herein, a mattress protector includes a unitary flat sheet for covering a surface of a mattress and providing a liquiphobic barrier for the surface. The flat sheet has four corners with cuts in the sheet proximal to and following a contour of each corner to form corner attachment members for extending from the surface and under the mattress, thereby securing the sheet to the mattress.
The term “liquiphobic”, as used herein, refers to generally repellant of liquids, including, but not limited to water, body fluids, beverages, etc.

DETAILED DESCRIPTION
As indicated above, it is desirable to have a mattress protector that is easy to manufacture and change. FIG. 1 is a top view of a mattress protector according to an aspect of the subject matter described herein. Referring to FIG. 1, the mattress protector comprises a unitary flat sheet 100 for covering a surface of a mattress. Unitary flat sheet 100 may be formed of any material that is itself liquiphobic or that can be chemically treated to be liquiphobic. In one example, sheet 100 is made of a spun-bound material and is treated to be liquiphobic. In the illustrated example, sheet 100 includes four corners with cuts 102 proximal to each corner and following a contour of each corner to form corner attachment members 104 for extending from the protected surface of a mattress under the mattress to secure sheet 100 to the mattress. Because corner attachment members 104 are part of sheet 100, the mattress protector illustrated in FIG. 1 is easy to manufacture as compared to mattress protectors that require straps, elastic, Velcro®, or other material to be sewn into the mattress protector.
FIG. 2 is a close up view of one corner of sheet 100 illustrating cut 102 and corner attachment member 104. As illustrated in FIG. 2, cut 102 extending around the contour of the corner forms a flap 106 that can rest on the protected surface of the mattress while corner attachment member 104 extends under the corner of the mattress.
FIG. 3 is a bottom view of a mattress protector showing attachment to a mattress. In FIG. 3, corner attachment member 104 extends under a corner of mattress 108. As a result, sheet 100 is securely attached to mattress 108 that can also be easily changed, simply by sliding each corner attachment member 104 out from under each corner.
FIG. 4 is a close up side view illustrating the attachment of sheet 100 to a corner of mattress 108. In FIG. 4, it can be seen that corner attachment member 104 extends under mattress 108 and then diagonally upwards along the side of mattress 108.
FIG. 5 is a close up end view illustrating the attachment of sheet 100 to a corner of mattress 108. In FIG. 5, corner attachment member 104 extends under mattress 108 and then diagonally up along the end of mattress 108.
In the examples illustrated in FIGS. 1-5, cuts 102 do not extend laterally from corner to corner of sheet 100. In an alternate implementation as illustrated in FIG. 6, cuts 102 extend laterally from corner to corner of sheet 100 such that the cut in one corner is joined with the cut in an adjacent corner on each end of sheet 100. In FIG. 6, cuts 102 follow the contours of each corner of sheet 100 and also the contour of each end of sheet 100. Because cuts 102 extend laterally such that the cuts in adjacent corners of sheet 100 are joined, sheet 100 can be more easily installed and removed from a mattress.
The result of the cuts illustrated in FIG. 6 is shown in FIG. 7. More particularly, FIG. 7 is a top view of a portion of sheet 100 where an end flap 110 is formed by cut 102. End flap 110 is positionable on a protected surface of a mattress. In FIG. 7, each end of sheet 100 forms a single corner attachment member 104 that extends under both corners of each end of a mattress. In FIG. 8, corner attachment member 104 extends laterally across the underside of mattress 108 to secure sheet 100 to mattress 108.
FIG. 9 is an end view of sheet 100 attached to mattress 108. In FIG. 9, corner attachment member 104 extends laterally under one end of mattress 108, and flap 110 covers the protected surface of mattress 108.
FIG. 10 is a flow chart illustrating a method for manufacturing a mattress protector as illustrated in FIGS. 1-9. Referring to FIG. 10, in step 120, a unitary flat sheet of material sized to cover a surface of the mattress is formed. Such a sheet may be formed of woven or nonwoven materials. In one example, the sheet is formed using a spin-bonding process. The material used to form the sheet may be liquiphobic or treated to be liquiphobic.
In step 122, cuts are made proximal to and following a contour of each corner of the sheet. In one example, the cuts do not extend from corner to corner. In an alternate example, the cuts extend laterally across the surface of each sheet from corner to corner to form flaps. After step 122 the sheet is a unitary piece of material with cuts that form attachment members to attach the sheet to a mattress and form a mattress protector.
Thus, a mattress protector according to the subject matter described herein can be made inexpensively and is easy to change. By not requiring straps or other sewn-in features for attachment, a mattress protector as described herein is easy to manufacture. Such a mattress protector may be disposable and can be replaced, for example, after each guest leaves a room in a hotel.
It will be understood that various details of the presently disclosed subject matter may be changed without departing from the scope of the presently disclosed subject matter. Furthermore, the foregoing description is for the purpose of illustration only, and not for the purpose of limitation.
