Abstract
The present invention disclosed a foam product and the manufacturing method thereof. The foam product includes a foam core, an outer skin, a cross-linked foam sheet and a bottom plate, wherein the aforementioned layers are all pre-made. The cross-linked foam sheet is laminated onto a bottom surface of the foam core, and the outer skin is then laminated onto a top surface and a periphery of the foam core. Lastly, the bottom plate is laminated onto the cross-linked foam sheet, wherein, the bottom plate has a non cross-linked foam sheet and a non-foam plastic plate, so that when the bottom plate is laminated onto the crossed-link foam sheet, the non cross-linked foam sheet is sandwiched between the cross-linked foam sheet and the non-foam plastic plate.
Claims5
A foam product comprising:
- a foam core having a top surface, a bottom surface, and a periphery;
- an outer skin having an outer surface, an inner surface, and a periphery, wherein the inner surface of the outer skin is laminated onto the top surface of the foam core;
- a cross-linked foam sheet having a top surface, a bottom surface, and a periphery, wherein the top surface of the cross-linked foam sheet is laminated onto the bottom surface of the foam core;
- a non cross-linked foam sheet having a top surface and a bottom surface, wherein the top surface of the non cross-linked foam sheet is laminated onto the bottom surface of the cross-linked foam sheet;
- and
- a non foam plastic plate laminated onto the bottom surface of the non cross-linked foam sheet;
- wherein the outer skin further covers the periphery of the foam core and the periphery of the cross-linked foam sheet, the outer skin does not exceed the bottom surface of the cross-linked foam sheet, wherein the top surface of the non cross-linked foam sheet covers the periphery of the outer skin.
A foam product comprising:
- a foam core having a top surface, a bottom surface, and a periphery;
- an outer skin having an outer surface, an inner surface, and a periphery, wherein the inner surface of the outer skin is laminated onto the top surface of the foam core;
- a cross-linked foam sheet having a top surface, a bottom surface, and a periphery, wherein the top surface of the cross-linked foam sheet is laminated onto the bottom surface of the foam core;
- a non cross-linked foam sheet having a top surface and a bottom surface, wherein the top surface of the non cross-linked foam sheet is laminated onto the bottom surface of the cross-linked foam sheet, and the cross-linked foam sheet has a thickness larger than the non cross-linked foam sheet;
- and
- a non foam plastic plate laminated onto the bottom surface of the non cross-linked foam sheet.
