Mattress Cover

Abstract

A cover assembly for bedding products, such as mattresses and/or box springs, that includes a sleeve shaped body and a selectively operable closure assembly disposed about an opening formed in the sleeve. The closure assembly includes first and second closure mechanisms that each, when closed, isolate a cavity defined by the sleeve from atmosphere. The first and second closure mechanisms overlie one another so that, when closed, only one of the closure mechanisms is exposed to atmosphere. The first and second closure mechanisms are preferably provided as zippers that can extend the entire longitudinal length of the sleeve opening and operate in generally opposite longitudinal directions.

What is claimed is: 
     
         1 . A cover for bedding products, the cover comprising:
 a body having an interior surface that faces a bedding product and an exterior surface that is exposed to atmosphere;   an opening provided along an edge portion of the body, the opening shaped to allow ingress and egress of the bedding product from the body; and   a first closure mechanism coupled to the body proximate the opening and a second closure mechanism coupled to the body proximate the opening and wherein only one of the first and second closure mechanisms is exposed to atmosphere when both the first and second closure mechanisms are closed.   
     
     
         2 . The cover of  claim 1  wherein the body of the cover is shaped to surround a bedding product that is further defined as at least one of a mattress and a box spring. 
     
     
         3 . The cover of  claim 1  wherein the first closure mechanism is further defined as a first zipper that extends a total length of the opening and the second closure mechanism is further defined as a second zipper that extends the total length of the opening. 
     
     
         4 . The cover of  claim 1  wherein the first zipper operates in a closing direction that is opposite a closing direction of the second zipper. 
     
     
         5 . The cover of  claim 1  further comprising at least one catch that is secured to the body and cooperates with one of the first and second closure mechanisms to bias the respective closure mechanism toward a closed position. 
     
     
         6 . The cover of  claim 5  wherein the at least one catch is exposed to atmosphere and cooperates with the one of the first closure and second closure mechanisms that is exposed to atmosphere. 
     
     
         7 . The cover of  claim 5  wherein the at least one catch is oriented at a crossing direction relative to a longitudinal axis associated with operation of the one of the first and second closure mechanisms. 
     
     
         8 . The cover of  claim 5  wherein the at least one catch is diagonally oriented relative to the one of the first and second closure mechanisms. 
     
     
         9 . A cover comprising:
 a sleeve formed of a flexible material;   an opening formed in the sleeve and shaped to allow passage of a bedding product into the sleeve;   a first closure mechanism secured to the sleeve about the opening and selectively operable to open and close the sleeve; and   a second closure mechanism secured to the sleeve about the opening and selectively operable to open and close the sleeve and so that the first closure mechanism is disposed between the bedding product and the second closure mechanism and isolates the bedding product from the second closure mechanism when the first closure mechanism is closed.   
     
     
         10 . The cover of  claim 9  wherein the first closure mechanism is further defined as an internal zipper and the second closure mechanism is further defined as an external zipper that overlies the internal zipper. 
     
     
         11 . The cover of  claim 10  wherein the internal zipper operates in a first closing direction and the external zipper operates in a second closing direction that is opposite the first closing direction. 
     
     
         12 . The cover of  claim 10  further comprising a catch having a first end secured to an exterior surface of the sleeve and a second end selectively engageable with at least one of a pull and a slider of the external zipper when the external zipper is in a closed position. 
     
     
         13 . The cover of  claim 12  wherein the catch is secured to the sleeve at a position offset from the at least one of the pull and the slider when the external zipper is in the closed position to bias the external zipper toward the closed position. 
     
     
         14 . The cover of  claim 13  wherein the catch includes a longitudinal axis that extends between the first end and the second end and is diagonally oriented relative to the slider when the external zipper is in the closed position. 
     
     
         15 . A method of forming a cover for a bedding product, the method comprising;
 forming a pocket having an interior surface shaped to face a bedding product and an exterior surface that faces atmosphere and an opening shaped to allow ingress and egress of the bedding product from the pocket;   connecting a first zipper to the pocket about the opening; and   connecting a second zipper to the pocket about the opening such that a first side of the first zipper faces a cavity defined by the pocket, a second side of the first zipper faces a first side of the second zipper, and a second side of the second zipper faces atmosphere.   
     
     
         16 . The method of  claim 15  further comprising orienting the first zipper relative to the pocket so that the first zipper opens when a slider of the first zipper moves in a first direction and closes when the slider of the first zipper moves in a second direction and orienting the second zipper relative to the pocket so that the second zipper opens when a slider of the second zipper moves in the second direction and closes when the slider of the second zipper moves in the first direction. 
     
     
         17 . The method of  claim 15  further comprising orienting the first zipper and the second zipper relative to the pocket so that the second zipper must be open to allow manipulation of the first zipper. 
     
     
         18 . The method of  claim 15  further comprising securing a catch to the exterior surface of the pocket proximate a location of a slider of the second zipper when the second zipper is closed. 
     
     
         19 . The method of  claim 18  further comprising orienting the catch at an oblique angle relative to the location of the slider of the second zipper when the second zipper is closed. 
     
     
         20 . The method of  claim 18  further comprising spacing the catch from the slider of the second zipper to bias the slider toward a closed position.
