Abstract

A pair of disposable absorbent shoe inserts includes first and second inserts, each including a porous upper layer which allows moisture to pass from the user's foot into an absorbent middle layer. A lower surface of the absorbent middle layer is attached to an impervious lower layer 40 which prevents moisture contact with the insole of the shoe. A lower surface of the impervious lower layer is attached to a release material layer 50 having a first pattern. A second shoe insert is similarly constructed, but provides a release material layer having a second pattern which is approximately a reverse image of the first pattern, and is non-overlaying to the first pattern. As a result, each insert acts as a release layer for the other insert. The layers of each insert are ultra thin and are bonded together to form a tapered edge around the circumference of the insert. An adhesive layer 60 is carried between the release layers of the first and second shoe inserts, thereby forming the pair of disposable absorbent shoe inserts. In use, due to the reverse image nature of the release material layers 50, approximately half of the adhesive layer is deposited on the lower surface of each impervious lower layer.

Claims1

Dependent claims

A pair of disposable absorbent shoe inserts attached together in a retail packaging configuration, comprising:

(A) a first shoe insert, comprising:
(a) an upper porous layer, defining a large number of small holes, through which moisture is able to pass;
(b) a highly absorbent middle layer having an upper surface adjacent to the upper porous layer;
(c) a moisture impervious lower layer, adjacent to a lower surface of the highly absorbent middle layer;
and
(d) a release material layer comprising strips of adhesive resistant material attached in a first pattern to the lower surface of the moisture impervious lower layer;
(B) a second shoe insert, comprising:
(a) an upper porous layer, defining a large number of small holes, through which moisture is able to pass;
(b) a highly absorbent middle layer having an upper surface adjacent to the upper porous layer;
(c) a moisture impervious lower layer, adjacent to a lower surface of the highly absorbent middle layer;
and
(d) a release material layer comprising strips of adhesive resistant material attached in a second pattern to the lower surface of the moisture impervious lower layer, wherein the first and second patterns are substantially reverse images;
and
(C) an adhesive layer carried between the first and second shoe inserts.
