DE19629607A1 - Protective sheath for mattress or bedding, with de-naturing fastening - Google Patents

Abstract

The fastenings, for example sliding clasp fastener and or hook pile fastener and or stud fastener possess de-naturing, overlapping tongues (4,5) which are alternately alkaline and strongly acid. Sufficiently long tongues can be used with a sufficiently high density, instead of always two overlapping de-naturing tongues.

Description

It is known mattresses and / or duvets, head pillows and bedding for allergy sufferers with protective covers too provided so that dust mites or mold or Dust mite droppings and / or other bacterial substances not from the mattress or from the duvets, pillows or affect the bedding on the human body can.

These protective covers are made of dense material and thus protect people. However, all closures, as well as the so-called tight zippers, are not tight, so that mold and / or other bacterial Substances grow through, even if they are allergenic have tight overlaps.

For this reason, the invention proposes a Provide overlap of the closures, which is denaturing and consequently prevents it from growing through.

The attached drawing shows:
with ( 1 ) z. B. a mattress and / or feather bed or pillow etc .;
with ( 2 ) the tight protective cover;
with ( 3 ) the closure, e.g. B. a zipper, a Velcro closure or a button closure or other similar Liche closures;
with ( 4 ) and ( 5 ) on the protective cover tightly glued or sewn on and then covered again with denaturing overlap tongues that are single and / or double, as shown, the z. B. zipper overlap sufficiently, and due to the fact that they are dena turing, ie strongly alkaline either soaked or with z. B. polyurethane or polyurethane-like adhesive, binding and / or spraying masses are superimposed, they form an absolutely denaturing surface and are thus protected against any bacterial infestation and thus overlap according to the invention sealing and denaturing the closure.

The double overlay between ( 4 ) and ( 5 ) naturally has the great advantage that here denaturing surfaces lie on top of each other and thus there is no growing through on the surfaces lying on top of each other.

According to the invention it is further proposed that the tongue ( 4 ) is preferably z. B. training strongly alkaline and the overlap tongue ( 5 ) to be highly acidic, ie a tongue has z. B. a pH greater than 9 and the other a pH around 2, ie it is impregnated with strong acidic substances or inoculated or sprayed or even produced as an acidic and / or alkaline substance.

Of course, the invention is not limited to the training forms described in detail above, but there are numerous modifications possible, but without deviating from the basic idea that protective covers for bed linen and / or mattresses are designed so that their closure with denaturing, overlapping and Closure overlap the tongues ( 4 ) and / or ( 5 ) is provided.

Claims (3)

1. Mattress or bedding protective covers, characterized in that they are attached to their closures, for. B. zipper and / or Velcro and / or button closure etc., with denaturing, overlapping tongues ( 4 ) and ( 5 ) are provided. 2. mattress or bedding protective covers according to claim 1, characterized in that the denaturing overlap tongues alternately once alkaline and once strongly acidic are trained. 3. mattress or bedding protective covers according to claim 1-2, characterized in that not always two overlapping denaturing tongues ( 4 ) and ( 5 ) must be used, but also z. B. sufficiently long tongue surfaces ( 4 ) or ( 5 ) in denaturing training give a sufficiently high density.
