Closure for a cover on a mattress and the like

Abstract

When hospital mattresses are to be disinfected or washed, measures must be taken to prevent the washing water from penetrating through the cover to the mattress. These special measures to make closures in the form of e.g. zippers, button closures or snap closures liquid-tight, may be tape or the like. To avoid these difficulties and drawbacks, the closure according to the invention may be constructed as a strip ( 9 ), which may be secured directly to the cover ( 3 ). Then, the strip ( 9 ) and the cover ( 3 ) may be cut to form an opening ( 8 ) through which the mattress ( 1 ) may be inserted. The subsequent closing takes place by means of a slidable strip ( 6 ) which may he applied and locked to the first strip (9). The strips ( 6, 9 ) are welded together at the ends to form an end closure ( 7 ). This results in a strong and liquid-tight closure so that the mattress may be washed/cleaned in a washing machine.

1 . A closure ( 2 ) for a cover ( 3 ) on a mattress, pillow or the like ( 1 ), which closure ( 2 ) must be liquid-tight so that the mattress ( 1 ) may be washed without the mattress ( 1 ) getting wet during this washing/disinfection, 
 characterized in that the closure ( 2 ) comprises partly a longitudinal strip ( 9 ) which is secured to the cover ( 3 ) and extends over the slot opening ( 8 ) in the cover, and which is provided with a gripping rib ( 5 ) outermost and a holding rib ( 4 ) mounted over the slot ( 8 ), respectively, and partly a strip ( 6 ) insertable thereon, said strip having gripping parts ( 10 ) extending around the gripping ribs ( 5 ) and holding parts ( 11 ) extending around the holding ribs ( 4 ), respectively.    
     
     
         2 . A closure according to  claim 1 , characterized in that the strip ( 9 ) and the ribs ( 4 ,  5 ) are made of plastics, such as TPU, and that the slide, the closure strip ( 6 ) with the parts ( 10 ,  11 ) is made of plastics, such as ABS.  
     
     
         3 . A closure according to claims  1  and  2 , characterized in that the strips ( 6 ,  9 ) are closed at the ends by means of a heat weld ( 7 ) after the mounting.  
     
     
         4 . A closure according to any one of claims  1 - 3 , characterized in that the slot opening ( 8 ) in the cover ( 3 ) is formed after the strip ( 9 ) has been secured to the cover ( 3 ).  
     
     
         5 . A closure according to claims  1 - 4 , characterized in that the closure ( 2 ) is mounted on one of the side faces of the mattress ( 1 ), such as the end face ( 3 ).
