Description

[Detailed description of the invention] "Purpose of the invention" This invention relates to the invention of a cover for covering the opening of a refrigerated or frozen case, and is used to remove refrigerated items from the opening of the refrigerated or frozen case over a long period of time, such as at night. It is an object of the present invention to provide an easy-to-handle opening cover that can be effectively covered to prevent loss of cold air under conditions where the temperature is not high, allowing efficient refrigeration and freezing to be carried out.

(Industrial field of use) A cover for covering the opening in a refrigerator/freezer case.

(Prior Art) It is well known that refrigerated or frozen cases (hereinafter simply referred to as refrigerated cases) are used in markets and other shops to display and sell foodstuffs, etc.・Hold under frozen conditions to prevent deterioration. By the way, it is natural that such refrigerated cases should be left in a state where customers can visually check the refrigerated and frozen products when the store opens, but it is not a good idea to leave the refrigerated cases as they are when the store is closed. It is necessary to maintain a large upper space at a cool temperature, and cold heat is lost from this space to the outside air, which increases energy costs. Therefore, in order to avoid such cooling and heat loss, the product storage section at the bottom of the case is covered with a cover while the store is closed.

(Problems to be solved by the invention) The above-mentioned covering covers conventionally used do not have sufficient heat insulation effect and are not easy to set properly over the product storage area, so loss of cold air cannot be avoided. However, there are disadvantages such as efficient refrigeration and cooling.

"Structure of the invention" (Means for solving the problem) The present invention was devised after repeated studies in view of the above-mentioned circumstances. This is a cover for covering the opening of a refrigerating/freezing case, which is characterized by integrally bonding a metal mesh material covered with a sheet.

(Function) By bonding and integrating the metal mesh material to the sheet-like heat insulating cover, a preferable stretched state is formed on the housing section, and by appropriately bending the circumferential side, it can be easily engaged with the circumferential side of the opening. At the same time, it reduces the gap that occurs around the cover periphery.

The metal mesh material is coated with resin to prevent corrosion due to moisture, etc.

(Example) To explain a specific embodiment of the present invention as described above as shown in the attached drawings, a heat insulating layer 11 such as a foamed resin and a reinforcing layer 12 such as a non-woven fabric are interposed between the insulation layer 11 and a reinforcing layer 12 such as an aluminum foil. A resin-coated wire mesh 4 laminated with a resin film 3 is bonded 15 to a sheet-like heat insulating cover 1 to which a reflective layer 13 is bonded and a waterproof coating layer 14 such as a polyethylene film is covered.
The cover shown in the figure is a single-layer or multi-layer cover and is applied to the above-mentioned refrigerating case 5, for example, as shown in FIG. 3. That is, a cooler 6, a cold air circulation fan 7, etc. are provided in the lower part of the refrigerating case 5, a refrigerated article storage part 8 is formed in the upper part, and the cold air is discharged from the discharge port 15 and discharged above the storage part 8. It is designed to be sucked in through the suction port 16 and guided to the refrigeration mechanism, and a shelf 9 or the like is provided at the top to display products that can be stored at room temperature when the store is opened. The above-mentioned covering cover according to the present invention is stretched over the housing part 8 in such a refrigerating case 5, and is fixed to the upper side of the housing part 8 by appropriately bending the circumferential side thereof. Note that the wire mesh 4 is not limited to a honeycomb shape, but may be a lattice shape or a diamond shape.

As shown in FIG. 3, the device of the present invention can be formed in such a way that the state in which the article is appropriately inserted into the storage section 8 can be formed in accordance with the storage condition of the article in the storage section 8, thereby making it possible to prevent cold air from flowing. By reducing the circulation space of the food, it is possible to advantageously distribute the cold air to the food.

"Effects of the Invention" The cover of the present invention as described above can be effectively extended and covered over the refrigerated article storage section 8 in this type of refrigerated case, and has the heat insulating layer 11. The storage section 8 and the inside of the case 5 above it are appropriately divided, and the cold air from the refrigeration mechanism is circulated only in the storage section 8, thereby effectively preventing the loss of cold energy during closing hours. However, since the resin-coated metal mesh material 2 is bonded as described above, it is not corroded by moisture etc. and has a good feel when handled.
A preferable expanded state is formed at the top, and gaps are not likely to be formed around the cover periphery, and the cover can be easily engaged with the circumferential portion of the accommodating portion 8 by appropriately bending the circumferential side as shown in Fig. 4 A and B. In addition, it can also be placed against a vertical case as shown in FIG. 5, which greatly simplifies its handling, making it a highly effective idea in practical terms.
