It relates to a cover that is sometimes stretched over the front side of the air curtain on the same opening surface and used to prevent unnecessary leakage of cold air, and in particular has a large number of relatively small holes on the entire surface of the cover body. By doing so, it is possible to allow ventilation between the inside and outside of the cover body through this hole, and the purpose of this ventilation is to reduce the temperature difference between the inside and outside surfaces of the cover body and prevent dew condensation on the inside surface of the cover body. It is.

を取付けたものである。In the illustrated embodiment, a transparent hard synthetic resin sheet 1 having elasticity, flexibility, and moisture resistance is folded vertically into two, and the two-fold synthetic resin sheet 1 is marked with its own two-fold line 2.
By applying prestress to the center and rolling back to a small diameter, a cover main body 3 is constructed which is large enough to cover the entrance/exit Roy' of the frozen display case when expanded in the vertical direction, and this cover main body 3 is folded in half. In the extended state, a large number of small U-shaped cutting lines are cut by pressing with a large number of U-shaped cutting blades (not shown), and at the same time, the material is surrounded by the same U-shaped cutting lines by press pressure. By pushing out the upper half 4 of the cover main body 3, a large number of air circulation holes 6 are formed in the lower edge of the upper half 4 of the cover body 3, each having an upward tongue-shaped valve piece 5 that is slightly tilted outward. In addition, in the lower half 7, a large number of air circulation holes 9 each having a downward tongue-shaped valve piece 8 tilted slightly inward at the upper edge are opened at once, and the cover is An upper edge reinforcing member 10 made of an opaque hard synthetic resin material and a lower edge reinforcing member 11 made of the same material are inserted into the reinforcing members 10 and 11 at both upper and lower edges of the main body 3.
This upper edge reinforcing member 10 is fixed together with the storage plate 15 to the upper side of the above-mentioned entry/exit Roy' with screws 16, and the cover main body 3 is attached to the entry/exit Roy'. Hanging retainers 17 and 18 hang down from the lower edge reinforcing member 11 and the lower side of the entrance/exit Roy' in a removable manner to maintain the cover main body 3 in the extended state of the entrance/exit shield.
This is the one with the attached.

え得る利点がある等の実用的効果を有するものである。Since the present invention is as described above, ``When there are no customers after closing, the main body of the cover is pulled out and extended, and the locking tool is engaged, thereby further cutting off the front side of the air curtain. Of course, creating an air layer can more reliably prevent cold air from escaping outside the display case and dust from entering the display case, but it is also possible to prevent cold air from escaping outside the display case and dust from entering the display case. Since the holes are opened at scattered locations, air circulates through the holes near the inner and outer surfaces of the cover body, significantly reducing the temperature difference between the inner and outer surfaces of the cover body. There is an advantage in that the above-mentioned object of the present invention can be fully achieved by reliably preventing dew condensation or freezing on the inner surface. The cover has an upward tongue-shaped valve piece that is slightly tilted outward, and an upward tongue-shaped valve piece that is slightly tilted inward on the upper edge of the through hole in the lower half. When the air curtain is stretched downward from the air outlet in the upper part of the case, the air curtain is sucked from the suction part in the lower part of the case to the lower part of the case. An inwardly sloping tongue-shaped valve piece prevents the relatively high temperature rising airflow generated along the curtain at the outer upper part of the case from flowing into the case. This has the effect of significantly reducing the operating rate of the refrigeration equipment that keeps the inside of the case below a predetermined temperature. A large number of air circulation holes with downward tongue-shaped flaps slightly tilted inward on the upper edge are formed by pressing the cover with a large number of U-shaped cutting blades by folding the cover body into an extended state. By extruding the area surrounded by the same U-shaped cut line with press pressure at the same time as processing, in other words, one-shot press processing has the remarkable effect of achieving extremely simple and efficient installation.Furthermore, the cover body can be folded in two. It is constructed by applying prestress to a synthetic resin sheet that self-rolls back to a small diameter around its bifold line.In other words, there is no special core for winding, so it can be rolled up extremely small when not in use. This is not only convenient, but also has practical effects such as the advantage that it can be done quickly and instantaneously since the upper and lower halves are rolled up at the same time.
