A low-temperature show case comprising an upper case having a front opening to be covered with revolving transparent glass doors, and a lower case having upper opening to be covered with slidable transparent glass doors, said upper case being constructed in the form of oriel with its transparent side walls oriented oblique towards the front opening, and being provided with an outlet for effusing cold air to form an air curtain just behind the opening, the outlet having larger width than the front opening so as to prevent the ambient air to flow into the case.

Low-temperature show case

In manufacturing an insulating box used for a low-temperature show case having a slidable transparent windows on the top opening thereof, a recess is formed on the upper front ends of inner and outer boxes of an insulating box, said recess being provided with a frame covering the gaps between said inner and outer boxes and having a groove for receiving therein a multi-layer transparent panel. After the multi-layer transparent panel is installed in the groove and fixed with a fixation frame, an expandable insulating material is injected into the spaces between said inner and outer boxes to form said insulating box.
