Slider with resistance to erosion and wear
View Patent ↗A slider resists erosion due to moisture, dirt and ultraviolet of sunlight and protects a pattern or the bonded surface from wear and tear. The slider contains a foam core, a top layer, a pattern, and a bottom layer. The foam core has a top surface, a bottom surface and edge surfaces. The top layer is a composite layer heat laminated to the top surface and edge surfaces of the foam core. The pattern is formed within the top layer and visible from outside of the top layer. The bottom layer is heat laminated to the bottom surface of the foam core.
1. A slider comprising:
a foam core having a top surface, a bottom surface and edge surfaces;
a first polyethylene foam skin having a bottom surface being laminated to the top and edge surfaces of the foam core;
a first patterned laminate including an inner plastic film having a bottom surface being heat laminated to a top surface of the first polyethylene foam skin; an outer plastic film having a bottom surface joined to a top surface of the inner plastic film; and a pattern placed in between the inner and outer plastic films and being visible from outside of the outer plastic film, wherein the outer plastic film together with the inner plastic film is embossed to define concaves in an exterior surface of the outer plastic film;
a second polyethylene foam skin having a top surface being heat laminated to the bottom surface of the foam core; and
a second patterned laminate including an inner plastic film having a top surface being heat laminated to a bottom surface of the second polyethylene foam skin; an outer plastic film having a top surface being heat laminated to a bottom surface of the inner plastic film; and a pattern being placed in between the inner and outer plastic films and being visible from outside of the outer plastic film.
2. The slider of claim 1 , wherein the foam core is made of polyethylene foam; each of the first and second polyethylene foam skins has a density greater than that of the foam core.
3. The slider of claim 2 further comprising a plastic plate having a surface being heat laminated to a bottom surface of the outer plastic film of the second polyethylene foam skin, wherein the pattern is visible from outside of the plastic plate.
4. The slider of claim 1 , wherein the foam core is made of non-polyethylene foam; the first polyethylene foam skin is laminated to the top and edge surfaces of the foam core via a first bonding film; and the second polyethylene foam skin is laminated to the bottom surface of the foam core via a second bonding film.
5. The slider of claim 4 further comprising a plastic plate having a surface being heat laminated to a bottom surface of the outer plastic film of the second polyethylene foam skin, wherein the pattern is visible from outside of the plastic plate.
6. The slider of claim 1 wherein the pattern of the first patterned laminate is substantially the same before and after the first patterned laminate is heat-laminated to the first polyethylene foam skin.
7. A slider comprising:
a polyethylene foam core having a top surface, a bottom surface and edge surfaces;
a first polyethylene foam skin having a bottom surface being laminated to the top and edge surfaces of the foam core;
a patterned laminate including an inner plastic film having a bottom surface being heat laminated to a top surface of the first polyethylene foam skin; an outer plastic film having a bottom surface joined to a top surface of the inner plastic film; and a pattern placed in between the inner and outer plastic films and being visible from outside of the outer plastic film, wherein the outer plastic film together with the inner plastic film is embossed to define concaves in an exterior surface of the outer plastic film;
a second polyethylene foam skin having a top surface being heat laminated to the bottom surface of the foam core; and
a plastic plate having a top surface being heat laminated to a bottom surface of the second polyethylene foam skin and a slippery bottom surface for sliding.
8. The slider of claim 7 wherein the pattern of the first patterned laminate is substantially the same before and after the first patterned laminate is heat-laminated to the first polyethylene foam skin.
9. A composite layer comprising:
a polyethylene foam skin; and
a first patterned laminate including an inner plastic film having a bottom surface being heat laminated to a top surface of the polyethylene foam skin; an outer plastic film having a bottom surface joined to a top surface of the inner plastic film; and a pattern placed in between the inner and outer plastic films and being visible from outside of the outer plastic film, wherein the outer plastic film together with the inner plastic film is embossed to define concaves in an exterior surface of the outer plastic film.
10. The composite layer of claim 9 further comprising a second patterned laminate including an inner plastic film having a top surface being heat laminated to a bottom surface of the polyethylene foam skin; a transparent outer plastic film having a top surface being heat laminated to a bottom surface of the inner plastic film; and a pattern being placed in between the inner and outer plastic films.
11. The composite layer of claim 10 further comprising a plastic plate having a top surface being heat laminated to a bottom surface of the outer plastic film and a slippery bottom surface for sliding, wherein the pattern is visible from outside of the plastic plate.
12. The composite layer of claim 9 further comprising a bonding film laminated to a bottom of the polyethylene foam skin so that the polyethylene foam skin is adapted to be heat-laminated to a non-polyethylene foam skin.
