Abstract
A foam product includes a foam core, an upper skin and a lower skin. The foam core has a top surface, a bottom surface, and a peripheral side surface. The upper skin covers both of the top surface and the peripheral side surface of the foam core, but extending not beyond the bottom surface of the foam core. And, the lower skin covers both of the bottom surface of the foam core and a peripheral end surface of the upper skin.
Claims11
A foam product, comprising:
- a foam core having a top surface, a bottom surface and a peripheral side surface;
- an upper foam layer covering the top surface of the foam core and at least a portion of the peripheral side surface of the foam core, but extending not beyond the bottom surface of the foam core, wherein the upper foam layer has an inner surface bonded to the top surface and the peripheral side surface of the foam core, an outer surface, and a peripheral end surface;
- and
- a compressed lower foam layer made of EPE or EPP and covering both of the bottom surface of the foam core and the peripheral end surface of the upper foam layer, and having an inner surface, an outer surface, and a peripheral end surface, wherein the inner surface of the compressed lower foam layer is bonded to the bottom surface of the foam core and the peripheral end surface of the upper foam layer;
- a non-foam plastic plate made of polyethylene and covering the outer surface of the compressed lower foam layer so that the compressed lower foam layer is disposed in between the foam core and the non-foam plastic plate, wherein the compressed lower foam layer is compressed and therefore having a thickness smaller than each of the non-foam plastic plate and the upper foam layer.

A foam product, comprising:
- a foam core having a top surface, a bottom surface and a peripheral side surface;
- an upper foam layer covering both of the top surface and an upper area of the peripheral side surface of the foam core, and having an inner surface and an outer surface, wherein the inner surface of the upper foam layer is bonded to the top surface and the upper area of the peripheral side surface of the foam core;
- and
- a compressed lower foam layer made of EPE or EPP and covering both of the bottom surface of the foam core and a lower area of the peripheral side surface of the foam core, and having an inner surface and an outer surface, wherein the inner surface of the compressed lower foam layer is bonded to the bottom surface and the lower area of the peripheral side surface of the foam core;
- and the upper and compressed lower foam layers are partly overlapped at the peripheral side surface of the foam core;
- and
- a non-foam plastic plate made of polyethylene and covering the outer surface of the compressed lower foam layer so that the compressed lower foam layer is disposed in between the foam core and the non-foam plastic plate, wherein the compressed lower foam layer is compressed and therefore having a thickness smaller than each of the non-foam plastic plate and the upper foam layer.
