Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a cold storage box used for keeping and transporting foods that require freshness, such as perishables.

[Conventional technology]

Traditionally, when transporting fresh foods such as seafood, vegetables, and fruits in a refrigerated state, the seafood is often stored in wooden or resinous boxes at ports or warehouses, and ice is mixed in during transport. At present, vegetables and fruits are packed in cardboard boxes at the local production area, cooled inside the truck bed with dry ice or ice, and then transported to the consumption area.

However, with these conventional cold storage and transportation methods, moisture from melting ice and condensation, and even moisture from the stored items themselves, can reduce the freshness of stored items or damage them due to freezing and thawing. This moisture must be disposed of in some way as it damages the paper and the like. For this reason, recently, cardboard boxes with styrofoam attached to the inner walls are used, styrofoam is formed into a box shape and ice or dry ice is placed inside, or specially processed water-absorbing mats are placed inside for transportation. We are beginning to see examples of this happening.

[Problem that the invention attempts to solve]

If Styrofoam is used to form a box shape and then transported while being kept cool with ice or dry ice inside, there is a problem with later disposal, and as has been the case in recent years, it is especially important to reduce the pollution caused by containers. When the big question is how to reduce the amount, some kind of improvement is desired. Additionally, conventional specially processed water-absorbing mats are expensive and cannot be said to be economically viable.

This idea was made in consideration of the above points, and its purpose is to provide an excellent cold storage effect, to facilitate the disposal of moisture, and to be economical, as well as to reduce the amount of water generated by cleaning up the container (disposal). The purpose of this project is to provide a cold storage box that has a completely different image from conventional cold storage boxes by minimizing environmental pollution and having a cosmetic effect.

[Means for solving problems]

That is, this idea involves pasting a foamed resin film on the entire surface of a paper having the same thickness as corrugated paperboard, and attaching this laminated board with continuous parts and folded parts that connect the bottom and side walls, the side walls and the side walls. Cut out a die to consist of a canopy, etc., and make crease lines diagonally between each of these boundaries and the connecting parts using perforated cuts at equal intervals so as to penetrate through the laminated board, and it can be assembled by simply folding these cuts. The inner box 1 is shaped like a dark box, and the multi-laminated board is made up of a curtain layer, a front liner layer, a corrugated core paper layer, and a water-absorbing liner layer. Cuts and folds are made near the edges to provide ventilation holes and cooling. A water-absorbing mat 2 which is folded back to back so as to have a medium accommodating part, and has a minced hole formed in the plate surface that forms the bottom part when folded, and which extends to the center of the corrugated cardboard core paper layer;
The means consists of a corrugated cardboard outer box 3 which can be assembled, which is made up of a bottom part, a side wall, a folding part, and a corrugated cardboard canopy 4 which is made up of a folding margin and a flat part.

[Effect]

Moisture coming out of the stored items and moisture condensing on the curtain layer of the water-absorbing mat due to cooling comes out through the perforated holes provided in the water-absorbing mat and enters the core paper layer of the corrugated cardboard. The water melted from the ice as a cooling medium infiltrates the foamed resin film of the inner box and adheres to the water-absorbing liner layer of the water-absorbing mat. Furthermore, since the inner surface of the inner box is made of a heat insulating material called a foamed resin film, the inside of the inner box remains cool without any cold air escaping. Due to this action, the atmosphere in the space inside the inner box is always kept in a high humidity state.

Although the details of the present invention have been described above, it is needless to say that the present invention is not limited to the illustrated example, and various modifications can be made within the same scope as a creation of technical ideas. For example, in addition to rectangular shapes, similar cold boxes can also be made in pentagonal or hexagonal shapes. In this way, the outer shape of the inner box and water absorption mat may be changed as appropriate depending on the shape of the outer box. Furthermore, not only a cardboard box but also a wooden box can be used as the outer box, and the outer box and the canopy may be integrated.

[Effect of idea]

As described in detail above, this invention is based on an inner cold storage box 1 that uses a laminated board material with a resin film made of a heat insulating material such as a foamed resin film pasted on the entire surface of cardboard similar to cardboard base paper. Especially devised water-absorbing mat 2
Ice, dry ice, etc. are placed in the cooling medium storage section of the water absorption mat 2, and fresh foods such as seafood and vegetables are placed therein, and the inner box 1 is placed in the outer box 3.
Since the entire container is stored and covered with a lid 4, the following effects can be achieved in keeping it cool and transporting it.

(1) The water-absorbing mat 2 absorbs the moisture coming out of the stored items and the moisture condensing due to cooling, and the water-absorbing liner layer of the water-absorbing mat 2 absorbs the moisture released from the melting of ice. It is extremely effective in preventing moisture leakage.

(2) The atmosphere inside the cold storage inner box 1 is always close to the dew point and kept at high humidity, especially for transporting seafood, vegetables, and fruits that require humidity and need to be kept in a cool atmosphere. Since it is always kept in good condition, it is extremely convenient for transporting fresh foods and the like.

(3) From the perspective of insulation effect, the board material of the inner cold storage box 1 is a layered composite material consisting of thick paper similar to corrugated paperboard and an insulating agent called a foamed resin film on the inside, but the cardboard itself is Since it has an insulating effect, it is more effective in preventing cold air from escaping. In addition, recently developed cold storage agents can sufficiently fulfill the initial purpose.

(4) When disposing of this cold box after use, the container is easy to dispose of, and the use of foamed resin is kept to a minimum, so there is little risk of it becoming a source of pollution.

(5) Since moisture leakage can be minimized, the cosmetic appearance of the outer box can be ensured, and trademarks and advertisements can be displayed on the outer box surface, which can increase advertising effectiveness.

(6) As is clear from the above explanation, the cold storage box according to the present invention is not particularly expensive and is economical.

As described above, this invention is unprecedented in terms of retaining cold air, preventing moisture leakage, preserving the freshness of perishable foods and preventing damage, preventing pollution, maintaining the cosmetic appearance of the outer box, and being economically efficient.
