Abstract
A hood is provided that includes a collar and a head covering. The collar includes at least one elastomeric layer configured to be sealingly fit around a body part of a wearer. The elastomeric layer includes perforations. The head covering includes at least one thermoplastic layer configured to receive a head of the wearer and terminating at an edge portion defining an opening configured for insertion of the head of the wearer. The head covering further includes integral connections extending through the perforations of the elastomeric layer to sealingly engage the head covering to the collar. Also provided are containment assemblies and methods of making and using the same.
Claims20
A hood, comprising:
- a collar comprising at least one elastomeric layer configured to be sealingly fit around a body part of a wearer, the at least one elastomeric layer having a plurality of perforations;
- and
- a head covering comprising at least one thermoplastic layer configured to receive a head of the wearer, the head covering further including a plurality of integral thermoplastic connections extending through the perforations of the elastomeric layer to seal the head covering to the collar.
A containment assembly, comprising:
- a collar comprising at least one elastomeric layer, the at least one elastomeric layer comprising a plurality of perforations;
- and
- a covering comprising at least one thermoplastic layer, a plurality of integral thermoplastic connections extending through the perforations of the elastomeric layer to seal the covering to the collar.
A method of joining together at least one thermoplastic layer and at least one elastomeric layer, comprising the steps of:
- providing a plurality of perforations in at least one elastomeric layer;
- juxtaposing the at least one thermoplastic layer and the at least one elastomeric layer;
- at least partially melting the at least one thermoplastic layer so that the at least one thermoplastic layer flows into the perforations;
- and
- solidifying the at least one thermoplastic layer so that connections integral with the at least one thermoplastic layer extend through the perforations.
