Description

[Detailed Description of the Invention] The present invention relates to a packaging box suitable for simultaneously packaging dry ice.

Packaging boxes with triangular cross-sectional roofs and handles along the ridges of the roof have become popular for packaging products such as shortcakes, ice cream, and chocolates because they have a good design and are stable when carried. However, this type of conventional packaging box requires simultaneous packaging with dry ice to maintain a cool atmosphere inside the box during the summer, etc. It was inconvenient that there was a storage section for dry ice.

The present invention is an improvement to this type of packaging box so that it can store dry ice stably and reliably while separating it from the packaged products by making good use of the roof space. That is, the present invention includes an outer box 1 which has a right-angled quadrilateral shape in plan and is fully open on at least one of the left and right side surfaces and closed on all other sides, and a box 1 that can be freely drawn out through a side opening 2 inside the outer box 1. Open-top inner box 3 stored in
At the upper end of the outer box 1, there is a cross section that can be unfolded and assembled freely, including the top surface 4 of the outer box 1 as a bottom wall, and in which a handle 5 is assembled and formed along the ridge during assembly. This packaging box is characterized in that a triangular roof part 6 is arranged in series, and the inside of the roof part 6 and the inside of the outer box 1 are communicated through a ventilation hole 7 formed in the top surface 4 of the outer box 1. .

In one embodiment of the present invention shown in the figure, the roof portion 6 includes a pair of left and right roof plates 6a, 6a connected to the left and right sides of the top surface 4 of the outer box 1 via folds. , cut plates 6b, 6b connected to opposite ends of the roof panels 6a, 6a through a fold, and triangular panels connected through a fold to one both sides of the roof panels 6a, 6a. Each of the side wall plates 6C has a triangular shape such that openings on both sides can be closed when the roof is assembled from the roof plates 6a and 6a. One side is connected to the side of the roof plate 6a, and the remaining two sides have folds 6d,
6d are coupled.

When assembling the roof section 6, from the unfolded state shown in FIG. 6d and 6d are bent based on the creases to form the side walls of the roof, respectively.

This situation is shown in FIG. Next, the other roof plate 6
Fold the sheet a along the crease and match its tip to the tip of the previously folded roof sheet 6a, and at the same time cut the sheets 6b and 6.
By folding up b to form a ridge, the roof 6 can be assembled as shown in FIG.

In order to restrain this roof part 6 in the assembled state, a tongue-shaped piece 6 is inserted from the panels 6b, 6b, as in conventional packaging boxes of this type.
e, one tongue-like piece 6e is bent into the roof, and the other tongue-like piece 6e is passed through the hole 5e' of one tongue-like piece 6C and overlapped on one roof plate 6a, and this overlapping part is Configuration 1. Fastened using cellophane tape (not shown) or the like. It's okay.

The present invention has the above-described structure, and when not in use, the roof portion 6 is unfolded as shown in FIG.

When using the product of the present invention, the product a to be packaged (for example, shortcake, buti ice cream, and chocolate tomato) is placed in the inner box 3, and then this inner box 3 is placed inside the outer box 1 on its side. It is stored through opening 2.

On the other hand, the roof part 6, which is connected to the outer box 1 so that it can be expanded and assembled freely, is assembled, for example, in the manner described above, and during the assembly, a predetermined amount of dry ice b (
(see Figure 4) is inserted.

The cold air from the dry ice b stored in this roof part 6 is passed through ventilation holes 7 formed in the bottom wall, that is, the top surface 4 of the outer box 1.
It flows into the inner box 3 through the tube, and maintains the inside of the inner box 3 in a cold atmosphere.

In this way, the packaging box of the present invention has a triangular roof and is configured so that the ridge of the roof can be used as a handle.
Like conventional packaging boxes of this type, it provides a good appearance and stability when being carried.

Furthermore, in the present invention, the inside of the roof section 6 is configured to be effectively used as a storage section for dry ice. Ice can be stored stably and reliably, and when stored, dry ice and packaged products can be separated from the outer box 1.
Since the dry ice is completely isolated by the top surface 4 of the package, there is no risk of the dry ice coming into direct contact with the packaged product, making it sanitary.

Furthermore, in the present invention, the storage area for dry ice is a mountain formed above the top surface 4 of the outer box 1, and the cold air from the dry ice is constantly drawn into the inner box 3 through the ventilation holes 7 on the top surface 4. flowing into
The inside of the inner box 3 can be efficiently maintained in a cold atmosphere.

Furthermore, in the present invention, since the inner box 3 can be freely stored and pulled out from the outer box 1, for example, as shown in FIG.
If it is displayed with 172 drawn out, a high display effect can be obtained, which is advantageous.

In the present invention, the structure of the inner box 3 is not particularly limited as long as the top surface is open, and for example, a double structure having a developed view as shown in FIG. 5 can be adopted.

FIG. 6 is a developed view of the outer box 1 shown in FIG. 1.
