Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a cold storage transport box that can store fresh food such as vegetables and fruits and precool it with vacuum or differential pressure, and after precooling, put the prechilled food in a cold storage state and use it for storage or transportation.

[Prior art]

In recent years, it has become common to perform pre-cooling treatment when shipping fresh foods such as vegetables and fruits, and the advantages of pre-cooling include stable quality, shipment to remote areas, adjustment of production areas for shipment, etc. Has been. The pre-cooling method includes vacuum pre-cooling, differential pressure pre-cooling, forced draft pre-cooling and the like. For example, the vacuum pre-cooling is a method of cooling by removing the heat of evaporation due to the evaporation of water from the pre-cooled food, and has the advantages of a high cooling rate and no uneven cooling. By the way, if the vegetables and fruits are housed in a storage room (vacuum chamber) that can be hermetically sealed and the storage room is placed under a reduced pressure (vacuum drawing), when the water content of the vegetables and fruits evaporates, the ambient heat is evaporated. The temperature of the fresh food can be lowered to a low temperature in a short time, and for example, the time for lowering from 30 ° C. to 5 ° C. is 20 to 30 minutes under 6 Torr. As a cold storage transport box that can be used for this vacuum pre-cooling or differential pressure pre-cooling, for example, as disclosed in Japanese Patent Laid-Open No. 63-178966, for ventilation, the side wall of the container body is cut out at the upper edge. The door that opens and closes this opening is
An elastic material such as rubber is hung and supported between the door frame and a window frame that guides the up-and-down movement of the door, and the back surface of the door is detachable from a protrusion provided on the side wall side of the container body. There is known a structure in which certain projections are provided and the opening / closing position of the door can be regulated by these projections and the elastic material.

[Problems to be solved by the device]

The refrigerated transport box disclosed in the above-mentioned publication has to be provided with an insertion groove for hanging an elastic material on the door and the window frame, which is troublesome to process, and also as a door stopper. An extra processing technique is also required for relative positioning of the projections used, and the structure is inevitably complicated, leading to cost increase, and there is a problem that it cannot be provided at low cost. Further, in order to open and close the ventilation opening of the cold-transportation boxes stacked in the storage chamber, it is necessary to operate the door for each box, which is troublesome. Therefore, an object of the present invention is to install a door slidably between a box body and a lid body, and at the time when the door has finished rising, an opening for ventilation can be formed on an upper side of a side wall of the box body. , It is convenient to perform the pre-cooling work by opening and closing the doors of each shipping box at the same time when they are stacked, and the door opening and closing structure can be simplified as much as possible and can be provided at low cost. In order to provide an improved cold storage box.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, one of the cold-insulating transport boxes, which is a feature of the present invention, is a cold-insulating transport box including a box body and a lid body that can be fitted and removed freely, and both the box body and the lid body have a heat insulating property. It is made of synthetic resin foam and has an upside-down U shape in which the upper edge portion of the box body is detachably fitted to the projecting edge portion and the lower half part of the peripheral wall of the lid body is detachable. Each of the fitting portions having a rectangular cross-section, at least one side wall of the box body is provided with a notch portion formed by cutting out from the convex edge portion of the side wall on the upper side of the guide wall portion continuing to the bottom portion, When the box body and the lid body are fitted to each other, the cutout portion is formed so as to be apparently formed as a ventilation opening portion by closing the convex edge portion near the peripheral wall portion of the lid body facing the cutout portion. A door body capable of opening and closing the ventilation opening is provided above and below along the guide wall portion and the peripheral wall portion where the guide wall portion is formed flush with each other. With slidably mounted to, the door body in which formed by drilling a window hole that can open the ventilation openings when said door body is raised. Further, the other one of the cold-insulated transport boxes which is the feature of the present invention is that the box body and the lid body which can be fitted and removed freely are made of synthetic resin foam having heat insulating property, and the upper edge of the box body is At least one of the box body is formed on the convex edge portion of the notch shape, and on the lower half side of the peripheral wall of the lid body at the fitting portion of the inverted U-shaped cross section which can be freely fitted and removed from the convex edge portion. The two side walls have a notch formed by cutting out from the convex edge of the side wall on the upper side of the guide wall part with the guide wall part left in the middle as a boundary, and a lower vent for lower side ventilation. Each of the openings is provided, and the cutout portion is
When the box body and the lid body are fitted together, the convex edge portion is closed at the peripheral wall portion of the lid body that faces the cutout portion, and it is apparently formed as the upper ventilation opening portion. And a door body capable of simultaneously opening and closing the lower ventilation opening is mounted slidably in the vertical direction along the guide wall portion and the peripheral wall portion which is formed flush with the guide wall portion, The door body is provided with a window hole capable of opening the upper ventilation opening when the door body is lifted.

[Action]

Fresh foods such as vegetables and fruits are stored in the box, and the cold storage transport box fitted with the lid is stacked in the storage room. And
When the door of the box at the bottom is slid toward the lid, the door of each box is pushed upward by the door of the box placed on the lower side, and each door rises at the same time. All the ventilation openings of the cold-insulated transport boxes stacked in parallel are opened all at once, and a ventilation part is formed on the side wall of each box. If the storage chamber is placed under a reduced pressure after forming the ventilation part, the decompression action also reduces the pressure inside the box of the shipping box through the ventilation part, and the moisture contained in the fresh food takes away heat from the surroundings and evaporates. The temperature of fresh food can be lowered. In addition, after forming the vent, cool air is sent from one vent of the box in the storage room to cool the contents in the box,
This cold air may be forcibly discharged from the inside of the box by suction from the other ventilation part, and cooling may be performed by differential pressure ventilation in which the cold air is circulated by a fan. When shipping a refrigerated transport box containing fresh food placed in a cold state, lower the doors of the boxes at the top to lower the doors of each box at the same time, forming a ventilation section. The ventilation openings were closed at once, taken out from the storage room, and transported in a cold state using a cold storage vehicle.
