ABSTRACT:
In a cold box having an outer container and an inner liner with the space therebetween filled with insulation and having an access opening capable of being closed with a door, a breaker strip is provided around the opening, fixed to both the outer container and the inner liner. The breaker strip is substantially a flat elongated member having two parallelly spaced flanges protruding from one side and extending the length thereof. The outer container is provided with an inwardly disposed flange disposed around the opening and the inner liner has an outwardly disposed flange, also disposed around the opening. Along each edge of both flanges is formed a U-shaped channel to receive a respective one of the flanges on the breaker strip. Male and female snap-type locking means are provided on each flange of the breaker strip and on each U-shaped channel, respectively, to secure the two when the two items are assembled.
