Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a foldable cold storage container, and more particularly to a cold storage container in which a folded portion is sealed so that cold air can be prevented from leaking to the outside.

[0002]

[Prior Art]

 This type of conventional cold storage container uses a highly heat-insulating raw material in which a plastic film and an aluminum foil film, etc. are laminated in order on one side of cardboard, and by punching out this raw material, the bottom plate, side plate, gable plate, It has been common to form a cold container by forming a blank plate in which a lid plate and the like are integrally connected in order and folding and assembling the blank plates in order.

[0003]

[Problems to be solved by the device]

 However, the above-mentioned conventional cold storage container, like a commonly used folding paper box, is simply a series of a bottom plate, a side plate, a gable plate, a cover plate, and the like, and these parts are mutually connected. Since no special processing or auxiliary pieces were applied to these parts or around these parts, when assembling the cold insulation container, gaps were formed in each folded part and corner part, and this There was a problem that impedes the cold insulation effect of the container.

The cold storage container of the present invention is a technique developed in view of the above-mentioned conventional problems. Particularly, in the present invention, the cold storage container has predetermined positions such as a bottom plate, a side plate, a gable plate, and a lid plate, or around them. By installing special processing and auxiliary pieces, it is possible to prevent gaps from appearing at the folded parts and corners of the container, thereby preventing cold air from leaking to the outside and producing a cooling effect. The present invention provides a cool container technology that can be used.

[0005]

[Means for Solving the Problems]

 The cold storage container according to the present invention is a technology that has fundamentally improved the above-mentioned conventional problems, and its gist is to center the bottom plate around the left and right side plates, the left and right lid plates, the upper and lower gable plates, and the upper and lower plates. A container made of a material having a high heat insulating property, which is formed by continuously connecting four upper corner pieces and connecting plates at four corners that can be folded in two through diagonal fold lines. And a locking piece is also provided on one side edge of the connecting plate, and the connecting plate folded in half inside the container is double-locked by these locking pieces. Is.

[0006]

[Action]

 As described above, the cold storage container according to the present invention has the locking piece protruding from the side edge of the connecting plate which is folded in two and folded into the container at the corner portion of the storage container. By locking the locking piece from the side edge of the connecting plate folded into the part to the other side edge, the two connecting plates can be integrally connected to each other. Further, since the upper edge piece having the locking pieces protruding from both ends is connected to the end plate, the connecting plate folded into the corner portion as described above is bent by bending the locking pieces downward. It can be locked by a locking piece.

Further, since the locking projections are provided at both ends of the one cover plate, and the notches into which the locking projections can be inserted are provided at both ends of the root of the other cover plate, the locking projections are inserted into the cuts. As a result, the two lid plates can be engaged with each other.

【Example】

 An embodiment of the cold insulation container according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing a main part of the cold insulation container of the present invention, and FIG. 2 is a blank plate of the cold insulation container of FIG. FIG. 5 is a plan view, FIG. 3 is a perspective explanatory view in the middle of assembly, FIG. 4 is a perspective explanatory view in a state where the assembly is in progress, and FIG. 5 is an external view after the assembly is completed.

In FIG. 2, reference numeral 1 is a blank plate of the cold insulation container of the present invention. This blank board 1 is composed of a base paper board in which foamed polyethylene and an aluminum vapor deposition film are laminated on a cardboard. The blank plate 1 is provided with side plates 3a and 3b and lid plates 4a and 4b, which are connected to the left and right sides of the bottom plate 2 through folding lines, respectively. Notches 5 are formed at both ends of the root of the cover plate 4a, and a pair of hand bank pieces 6 are provided by cutting lines and fold lines at the center of the cover plate 4a. Further, an elongated hole 7 through which the hand bank piece 6 can be inserted is bored in the central portion of the other cover plate 4b, and locking projections 8 which can be inserted into the notches 5 are further provided at both end edges thereof. It is projected.

Gable plates 9a and 9b, connecting pieces 10a and 10b, and upper edge pieces 11a and 11b are sequentially arranged above and below the bottom plate 2 through folding lines, and locking pieces are provided at both ends of the upper edge pieces 11a and 11b. 12 are arranged in series. At the edges of the side plates 3a, 3b and the end plates 9a, 9b, connecting plates 13 are connected to each other via fold lines, and these connecting plates 13 are diagonal fold lines a and these diagonal fold lines a. It is constructed so that it can be folded in two along a diagonal line a by a cutting line b provided continuously at the tip of the. Further, fan-shaped locking pieces 14 are provided in a projecting manner on one side edge of these connecting plates 13, that is, on one side edge closer to the cover plates 4a and 4b.

In assembling the cold insulation container according to the present invention, as shown in the order of FIG. 3, FIG. 4, FIG. 1 and FIG. 5, the side plates 3a, 3b and the end plates 4a, 4b are erected around the bottom plate 2, The connecting plate 13 connected to the side ends of both parties is folded in half along the diagonal fold line a and the cutting line b, and is folded inside the container. While being bent, it is locked to the other bent portion of the connecting plate 13, then the upper edge pieces 11a, 11b are bent horizontally above the container, and the upper edge pieces 11a, 11b are perforated. The locking pieces 12 are bent downward, and the locking pieces 12 are locked to the above-mentioned two-folded connecting plate 13 to double-lock the corner portions of the container.

Subsequently, this time, the cover plate 4a is folded on the upper edges 11a and 11b, and the cover plate 4b is further folded on the cover plate 4a. 4a, 4b can be engaged with each other to assemble the entire container.

[0013]

EFFECTS OF THE INVENTION Since the cold insulation container according to the present invention has the structure and operation as described above, it is possible to doubly lock and connect the bent and folded portion of the container, especially the corner portion thereof. This can prevent a gap from being formed at the joint of the container. Therefore, the container of the present invention has a feature that it can be formed as a whole having a heat insulating material and a gap is not formed in the container, so that a container having an extremely cool effect can be constructed.
