Abstract

See full text

The invention relates mold, particularly a mold for producing foam articles. In a preferred embodiment, the mold comprises a lid and a bowl releasingly engageable to define a mold cavity, the lid comprising: (i) a vent having a passageway for gas to escape from the mold cavity, and (ii) a plurality of grooves connected to the vent. The use of a plurality of grooves/slots in the mold cavity surface effectively acts as a siphon to draw gas away from the composition to be molded. The plurality of grooves/slots is connected to one or more vents which then allows for escape of the gas from the mold cavity to the exterior of the mold.
