Encapsulated end caps and method of making the same for a writing board tray
View Patent ↗A writing board support tray comprises a support tray having an end portion coated with an elastomeric material with the support tray and the elastomeric material being substantially inseparably bonded or attached to each other. Further, a writing board support tray comprises a support tray substantially completely coated with an elastomeric material with the support tray and the elastomeric material being substantially inseparably bonded or attached to each other. Additionally, a further preferred embodiment, a writing board support tray comprises a support tray with a front end substantially completely coated with an elastomeric material with the support tray and the elastomeric material being substantially inseparably bonded or attached to each other. In addition, a writing board comprising a writing surface and a support tray, wherein the peripheral edge of the writing surface is encapsulated by an elastomeric material and the support tray is constructed completely out of the elastomeric material.
1. A composite end cap comprising:
an outer layer; and
an inner core having an external portion connected to said outer layer, an internal portion, a planar support tray receiving recess, and at least two attachment channels, one being a through hole, the attachment channels being perpendicular to said planar support tray receiving recess;
wherein said outer layer entirely covers all external edges and corners of said inner core; and
wherein said inner core and said outer layer form an integral end cap for capping a support tray that supports erasers, markers, chalk, or writing utensils in conjunction with a writing board, chalkboard, dry erase board, or writing surface.
2. The composite end cap of claim 1 , wherein said outer layer is over-molded onto said external portion of said inner core.
3. The composite end cap of claim 1 , wherein said external portion comprises an external top area, an external bottom area, an external encasing side area, an external receiving side area, an external back area, and an external front area.
4. The composite end cap of claim 1 , wherein said inner core comprises a thermoplastic polymer.
5. The composite end cap of claim 4 , wherein said thermoplastic polymer is selected from the group consisting of polypropylene, thermal polypropylene, and combinations and derivatives thereof.
6. The composite end cap of claim 1 , wherein said outer layer comprises a thermoplastic polymer.
7. The composite end cap of claim 6 , wherein said thermoplastic polymer is selected from the group consisting of polyethylene, thermal polyethylene, silicone, and combinations and derivatives thereof.
8. The composite end cap of claim 1 , wherein said inner core comprises at least one internal receiving attachment plate.
