Passageway resistant to capillary transport |
摘要 |
A passageway resistant to capillary transport and which is defined by a circumscribing wall made of heat sealable plastic sheets which are joined along longitudinally extending fin-type heat seals. The joints each have a fillet section which is in intimate contact with the wall along portions contiguous the heat seals and which fills the capillary channels therebetween. The fillets are made of a material which will not be displaced by a liquid which contacts the passageway in use.
