Abstract
An in-situ foam core component having first and second opposed thermoformed skins each having a thermal bond to an in-situ foam core disposed there between. At least one embossment In one of the skins joined to the other skin forming a pinch off junction. A through hole is formed in the pinch off junction sized to receive a fastener so that the embossment provides a sleeve structure which can transmit load between the first and second skins when the in-situ foam core component is attached to a member using a fastener extending through the hole.

An in-situ foam core component capable of attachment to a member using a through hole fastener, comprising:
- first and second opposed thermoformed skins each having a thermal bond to an in-situ foam core disposed therebetween, including a recessed first embossment on the first skin and an aligned recessed second embossment on the second skin, the first and second embossments being joined together at a welded pinch off junction;
- wherein a through hole is formed through the pinch off junction leaving an annular welded joint about the hole sized to receive a fastener there through so that the aligned first and second embossments provide a sleeve structure having an outer wall which is thermally bonded along its entire length to the in-situ foam core and can transmit load between the first and second skins when the in-situ foam core component is attached to a member using a fastener extending through the hole.
An in-situ foam core component capable of attachment to a member using a through hole fastener, comprising:
- first and second opposed thermoformed skins which are thermally welded directly to one another along a peripheral edge and at least one pinch off junction to define a cavity therebetween;
- an in-situ formed foam core formed with the cavity and thermally bonded to each of the thermoformed skins, and
- wherein, at least one embossment on the first skin is joined directly together with the second skin at the at least one pinch off junction without having the material forming the foam core located therebetween;
- wherein a through hole is formed in the at least one pinch off junction leaving an annular welded joint about the hole sized to receive a fastener so that the embossment provides a sleeve structure having an outer wall which is thermally bonded along its entire length to the in-situ foam core and can transmit load between the first and second skins when the in-situ foam core component is attached to a member using a fastener extending through the hole.
