Abstract

A reverse molded, plant-on decorative panel component comprises a panel portion lying on a first plane, a skirt portion, and a contoured portion. The skirt portion has a first surface adapted to be exteriorly disposed and an opposite second surface adapted to be interiorly disposed in order to be adhesively secured to a planar surface. The contoured portion extends outwardly from and surrounds the panel portion and interconnects and is integral with the panel portion and the skirt portion. The skirt portion extends peripherally about the contoured portion.

First claim

We claim as follows:

1. A reverse molded wood composite door skin, comprising:
a panel portion lying on a first plane;
a style and rail portion having a first surface adapted to be exteriorly disposed and an opposite second surface adapted to be interiorly disposed in order to be adhesively secured to a planar surface; and
a contoured wall extending integral with and surrounding the panel portion, and the style and rail portion extending integral with and surround the contoured portion.

2. The door skin of claim 1 , wherein the contoured wall is molded in a rectangular shape surrounding the planar portion.

3. The door skin of claim 1 , wherein the contoured wall portion includes a wall portion that is integral with and extends upwardly from the adjacent stile or rail portion at an angle of about 25° to about 35° above the horizontal.

4. The door skin of claim 3 , wherein the contoured wall portion further includes a U-shaped wall portion having its outer end integral with the wall portion and its inner end integral with the planar portion.

5. The door skin of claim 4 , wherein the U-shaped wall portion contains an inner surface at the base of the U which lies in the same plane as the second surface of the stiles and rail portion.

6. The door skin of claim 1 , wherein style and rail portion lies in a second plane.

7. The door skin of claim 6 , wherein the first plane and the second plane are approximately parallel.

8. The door skin of claim 6 , wherein the second plane is disposed at an angle of between about five degrees to about fifteen degrees relative to the first plane.

9. The door skin of claim 1 , wherein the panel portion has a first caliper and the contoured wall has a second caliper, said second caliper being less than said first caliper.

10. The door skin of claim 1 , wherein said panel portion is rectangular.

11. A method for molding a reverse molded wood composite door skin, comprising the steps of:
a. providing a mold press having an upper mold die and a lower mold die, wherein the upper die has a planar zone, a contoured zone, and style and rail zone, and the lower die has a planar zone, a contoured zone, and a style and rail portion complementary to the zones of the upper die, respectively;
b. positioning a cellulosic mat between the upper and lower dies; and
c. compressing the cellulosic mat between the upper and lower dies and heating the cellulosic mat to a temperature sufficient to form the door skin having
i. a panel portion lying on a first plane;
ii. a style and rail portion having a first surface adapted to be exteriorly disposed and an opposite second surface adapted to be interiorly disposed in order to be adhesively secured to a planar surface; and
iii. a contoured wall extending integral with and surrounding the panel portion, and the style and rail portion extending integral with and surround the contoured portion.

12. The method of claim 11 , wherein the cellulosic mat comprises cellulosic fibers and a thermosetting binder.

13. The method of claim 12 , wherein the thermosetting binder is urea formaldehyde, melamine formaldehyde, and/or phenol formaldehyde.

14. The method of claim 11 , cellulosic mat comprises at least about 80% fibrillated, refined cellulosic fibers (based on total, dry fiber weight).

15. The method of claim 11 , wherein the contoured wall is molded in a rectangular shape surrounding the planar portion.

16. The method of claim 11 , wherein the contoured wall portion includes a wall portion that is integral with and extends upwardly from the adjacent stile or rail portion at an angle of about 25° to about 35° above the horizontal.

17. The method of claim 16 , wherein the contoured wall portion further includes a U-shaped wall portion having its outer end integral with the wall portion and its inner end integral with the planar portion.

18. The method of claim 17 , wherein the U-shaped wall portion contains an inner surface at the base of the U which lies in the same plane as the second surface of the stiles and rail portion.

19. The method of claim 11 , wherein style and rail portion lies in a second plane.

20. The method of claim 11 , wherein the panel portion has a first caliper and the contoured wall has a second caliper, said second caliper being less than said first caliper.
