Remove the transparent door 2 while the cover 25 is in the
This cover can be removed by pulling out. Further, since the vertical dimension of the contact piece 50 of the door stopper 41 is larger than the distance between the lower end of the shade 17 and the transparent door 2, the structure is such that the cover 25 cannot be removed unless the door is removed.

Further, as shown in FIG. 5, when the cover 25 is stored, the door stopper 41 slides as described above, the cover depth becomes L ₁ , and the front end of the cover 25 is positioned at an appropriate position below the fluorescent lamp 23. Since the cover 25 does not cover the entire lower part of the fluorescent lamp 23, the light from the fluorescent lamp 23 passes in front of the front end of the cover 25, and the rear edge of the transparent door 2 and the upper part of the front end of the projecting wall 12. The inside of the refrigerator 6 is irradiated through a transparent member 60 located between the

Therefore, the cover 25 of the refrigerating case is pulled out from the storage chamber 5, the front member 27 of the cover 25 is rotated and pulled downward, the locking opening 35 is positioned in the lock ring 33, and the handle is inserted into the handle opening 36. When penetrated, the contact piece 50 of the door stopper 41 contacts the rear edge of the transparent door 2 at the position of the cover 25 and presses the transparent door forward, causing the transparent door 12 to not be completely closed. Even if a gap is formed between the packing 2B and the decorative member 32, the transparent door 12
is moved by being pressed by the abutment piece 50, and the front edge gasket 2B abuts against the decorative member 32, thereby completely closing the opening 3A. For this reason, cover 2
5 covers the opening 3A, the opening 3A
is automatically closed by the transparent door 12, and there is no need for the user to check whether the opening 3A is closed. temperature rise can be avoided, and the quality of the products in the refrigerator can be maintained for a long period of time.

Also, when the cover 25 is folded and stored in the storage chamber 5, the depth dimension of the cover 25 is equal to the door stop 41.
becomes shorter due to the sliding of the cover 25, and the front end reaches the dimension _L1 and is located below the fluorescent lamp 23, and the light from this fluorescent lamp passes in front of the front end of the cover 25, further passes through the transparent member 60, and reaches the interior 6 of the refrigerator. The interior of the warehouse can be illuminated to improve the display effect of stored products.

Note that the present invention is not limited to the above-mentioned implementation, and even in the case of a refrigerated case with a locking method other than the above-mentioned embodiment and a transparent door with multiple plates, the trailing edge of the transparent door is attached to the cover as in the above-mentioned embodiment. Similar effects can be obtained by attaching a door stopper 41 that presses the door.

(g) Effects of the invention Since the invention is a refrigerated store case constructed as in the above embodiment, when the cover is pulled out at the time of store closing, the door stopper attached to the rear of the cover will close to the rear edge of the door. Even if a gap remains between the front edge of the door and the top of the insulation box, the door is pushed forward via the door stopper by pulling the cover forward, and when the door is locked, the gap is closed. The door can be automatically and completely closed. Therefore, when the cover is pulled out and locked, the door is always completely closed, which eliminates cold air leakage and outside air intrusion into the refrigerator, and prevents frost buildup and products inside the refrigerator. temperature rise can be avoided.
