Description

  The present invention relates to a foldable assemblable cold storage container used for storage and transportation of articles requiring cold storage.

  For example, in refrigerated living cooperatives (hereinafter referred to as “co-ops”), delivery of items that require refrigeration, such as frozen foods and foodstuffs, from the distribution center in the cold storage state, etc., with a lid made mainly of foamed resin A heat insulating container having a heat insulating structure is generally used, and normally, the delivery object such as food or food is accommodated together with a refrigerant such as dry ice or a cold storage material.

  Such cold storage containers are delivered to private homes, then empty containers are returned to the distribution center and used again. To prevent cracks, chips, dirt, etc. due to repeated use, the outer surface of the container is waterproofed. A cold storage container of a configuration form that is covered with a cover made of a flexible sheet material is used.

  By the way, in the above-mentioned cold storage container, if an empty container is recovered as it is, it is difficult to handle and requires a large loading space, which causes problems in transportation efficiency and workability.

  Therefore, the bottom plate and the four side plates constituting the container body are individually formed by a heat insulating panel made of foamed resin, and each of these panels is assembled to a box-shaped cover body made of a flexible sheet material such as a waterproof cloth. Containers that are configured to be separable and that can separate the heat insulating panels from the cover body and fold the cover body when transporting an empty container have been proposed (for example, Patent Documents 1 and 2). reference).

  In the case of Patent Document 1, in order to prevent the opening edge of the cover body from spreading outward from the container body in the assembled state, a plastic edge member and a corner member are attached to the opening edge of the cover body. Although the opening edge is held in a flat rectangular shape, each side plate of the container main body and the cover body are not joined together, so that the gap between the side plate and the side surface of the cover body may be opened. May swell up and become unsightly in appearance.

  Moreover, in the case of patent document 2, the hook piece is attached inside the opening edge part of the outer box (cover body) which consists of flexible sheet | seat materials, and the upper end part of each side wall board of the four sides of a container main body is said By fitting and engaging with the flange, it is fixed in a joined state along the inner surface of the outer box. In this case, the fitting operation at the time of assembling becomes troublesome, and a rigid piece is caught when a delivery object such as food or food that requires cold storage is taken in and out, and damages the food of the delivery object. There is probably a fear.

  Further, if the hook piece is attached to both the long side and the short side, the side piece on the short side may be disturbed when folded inward. Even if separated, the flange comes into contact with the flange on the long side and cannot be folded low.

In addition, when the outer surface of the side plate and the inner surface of the side surface portion of the cover body are simply locked and stopped by a hook-and-loop fastener, it is easy to come off when an external force is applied to the cover body, in particular, the side plate on the long side is more likely to come off. It is not satisfactory as a fixing means.

  The present invention has been made in view of the above, and as a cold storage container formed by assembling and separating the bottom plate and four side plates of the container body with respect to the box-shaped body cover, at least both side plates on the long side side and It is intended to provide a cold storage container that can be easily and reliably coupled and fixed to the side surface portion of the main body cover, and can be used with good appearance, and further, the both side plates on the long side are coupled. Cold storage container that can easily fold the main body cover as it is, cold storage that does not interfere with delivery / removal of delivery objects such as food and ingredients, and that can maintain a stable combined state without damaging the delivery object A container is provided.

  The present invention solves the above-described problem, and is formed in a container body assembled into a flat rectangular box shape by a bottom plate and four side plates, and an open top box shape covering the outer periphery of the container body. A main body cover and a lid covering the upper surface of the container main body. The bottom plate and the four side plates of the container main body and the lid body are each formed of a foamed resin panel, the bottom plate and the four side plates. In the cold storage container provided so as to be separable from the main body cover, at least both long side plates of the container main body are provided with a pair of through-holes in the upper region at intervals in the width direction. On the other hand, two sets of connecting pieces that can be inserted through the two sets of through-holes and can be connected to each other are provided on the inner surfaces of both side portions on the long side of the main body cover. In the state, the two The connecting piece is inserted in the through hole and connected inward so as to draw the side plate, whereby the side plate of the container main body and the side surface portion of the main body cover are combined at the upper part. .

  According to the cold storage container, at the time of assembly, at least the long side plates are placed in the upper body cover, and a pair of connecting pieces on the side surface of the body cover is connected to the upper portion of the side plate. The two side plates are inserted into a pair of through holes and connected on the inner side so as to draw the side plates, so that the side plates can be drawn to the side surface side of the main body cover and fixed together. For this reason, the coupling operation during assembly is easy, and in the assembled state, at least the long side plates are securely and securely fastened to the inner surface of the side surface of the body cover in a stable manner. Even if an external force is applied to the main body cover, there is no possibility that the connection will be released, and the side plate and the main body cover will not open unreasonably.

  In particular, a set of two through-holes provided in at least both long side plates of the container body form a vertically long slit, and a pair of two connections on both long side surfaces of the main body cover. The strip has a strip shape that can be inserted into the slit-shaped through hole, and a hook-and-loop fastener member that can be engaged with each other is attached. The strip-shaped connecting piece is inserted into the through-hole and extends along the inner surface of the side plate. What is engaged and connected by the hook-and-loop fastener member in this state is preferable.

  That is, with the above configuration, the force acting on the portion of the through hole is dispersed by tightening the strip-shaped connecting piece, so that the periphery of the through hole in the side plate is deformed or the portion of the through hole is Can prevent cracks and breakage from occurring. Moreover, in order to use the hook-and-loop fastener member, the tightening by engagement connection can be adjusted steplessly, and when the tightening force is loosened during use, it can be easily adjusted by adjusting the engagement and connection position of the hook-and-loop fastener member. It can cope and can hold the tightening state well. Further, since the strip-shaped connecting pieces are engaged and connected by the hook-and-loop fastener member in a state along the inner surface of the side plate, a large overhang due to the connecting pieces does not occur inside the container, and a delivery object such as food or foodstuffs There is no hindrance to taking in and out, and even if a delivery object such as food comes into contact with the strip-shaped connecting piece or the hook-and-loop fastener member, it is difficult to be damaged.

  In the cold insulation container, it is preferable that the slit-shaped through hole is tapered so that the inner surface side of the side plate becomes narrower. That is, even if the opening width on the side plate inner surface side of the through hole is such that the strip-shaped connecting piece can pass through, the opening width on the outer surface side is large and the insertion operation of the connecting piece can be performed easily. In the opening on the side, the gap between the connecting pieces can be made small, and no extra gap is formed. Therefore, it is possible to suppress the escape of cold air and the decrease in the cooling effect.

  In the cold storage container, a recess into which the connecting piece is continuously fitted from the through hole is formed on an inner surface between the pair of through holes in at least both long side plates of the container body. It is preferable that the connecting pieces are engaged and connected in a state in which the connecting pieces are fitted in the recess. As a result, no extra overhang is generated by the connecting piece on the inner surface side of the side plate, and therefore the connecting piece does not obstruct the loading / unloading of the delivery object.

  In the cold insulation container, when a portion continuous from the opening end portion on the inner surface side of the side plate of the through hole to the inner surface between the pair of through holes or the concave portion is chamfered in a curved shape, It is possible to prevent biting deformation and breakage of the peripheral edge of the through hole due to tightening of the connecting piece.

  In the cold container, in the assembled state, the short side plate is sandwiched between the long side plates and the bottom plate is connected to the long side plate and the short side in the assembled state. Those that are detachably fitted inside the both side plates and held at the bottom position are preferable because the assembled state can be satisfactorily maintained.

  In the cold storage container, the main body cover can be folded so that the side plates on the short side are folded inward while the both side plates on the long side of the container main body are coupled to the side surfaces of the main body cover. Further, the side plates on the short side of the container main body are belt-like engagement and connection attached to the connecting boundary between one side surface on the long side of the main body cover and both side surfaces on the short side. Are connected to each other so that they can be folded in parallel with each other on the long side, and between the one side plate on the long side and the both side plates on the short side. It is assumed that the main body cover is provided so as to be foldable with the bottom plate sandwiched therebetween. Accordingly, the bottom plate and the side plate on the short side can be overlapped and folded with a low bulk while the side plate on the long side is coupled and fixed to the side surface portion of the main body cover.

  On the inner surface of the side plate on the long side, grooves having a concave shape are formed at intervals in the longitudinal direction, and recesses having a width larger than that of the grooves are formed near both ends in the width direction. It is assumed that the side surface on the end side in the longitudinal direction of the side plate of the recess forms an inclined surface.

  As a result, when the side plate on the short side is sandwiched between the side plates on the long side and positioned at the side end, no catching occurs and the side plate is not damaged.

  According to the cold storage container of the present invention, the bottom plate and the side plate of the container body can be separated and assembled with respect to the main body cover, and at least the long side plates of the container main body and the side surface portion of the main body cover are connected to the main body. By connecting two sets of connecting pieces on the side of the cover through two sets of through-holes in the upper part of the side plate and connecting them inward, it is easy and surely fixed and fixed with good stability. Even if an external force is applied to the main body cover, the above connection is not easily released, and the appearance can be used with good appearance.

  In particular, as a band-like connecting piece that can be engaged and connected by a hook-and-loop fastener member, the connecting piece is inserted into a pair of slit-like through holes in the side plate and engaged and connected along the inner surface of the side plate. In this case, the engaging and connecting operation is easy, the degree of tightening by engaging and connecting can be adjusted steplessly, and the coupling and fixing can be performed stably. In addition, since there is no excessive overhang caused by the connecting piece, it does not interfere with the removal and entry of the delivery object such as food and ingredients, and it is difficult to be damaged even if the delivery object contacts the connecting piece. This makes it easy to store and take out objects.

  Next, embodiments of the present invention will be described based on examples shown in the drawings.
