Considering handling during distribution such as transportation and storage, it has high product pressure strength and high impact strength during transportation, and also has excellent workability and economic efficiency. A wrap round type outer case that can be used at the same time is widely adopted.

Incidentally, individual products (small boxes) housed in such an outer case may be repackaged in a gift case or a display case for display, depending on the necessity of distribution. Even when the transaction unit at the retail store is less than or equal to the case, each product (small box) is taken out by unpacking the outer case. In such a case, the empty outer case is normally crushed and flattened and discarded.

[0004]

However, since the outer case is made of corrugated cardboard having high strength of A or B flute, it has a strong structure, and unpacking work is troublesome. Further, the work of manually crushing an empty case, crushing it into a prone shape, and collecting it requires a lot of labor and is difficult. For example, when unwrapping the conventional wrap round case shown in FIG. 4, the glue allowance 20 is cut off and the top board 2 is cut with both hands.
1 is pulled up, the inner and outer flaps 22 and 23 are torn or cut to form a gap between the products g, and a finger is put in the gap to take out the product from the end. After taking out the product, the outer side case is disassembled by breaking the back side and inner and outer flaps.

In view of the above, the present invention solves the above-mentioned problems and makes it possible to completely open the top surface and the back side surface via a zipper, and the packaging case can be easily opened after taking out the content product. The purpose of the present invention is to propose a wrap-round type easy-opening corrugated cardboard case that will be in a prone state and will be easy to perform post-treatment such as collection.

In order to achieve the above-mentioned object, the invention of the present invention provides a pair of side plates on opposite sides of a rectangular or rectangular bottom plate, and one of the pair of side plates has the same size as the bottom plate. Connect the board and the connecting margin to each other in order.
The pair of side plates are connected to each other in the shape of a rectangular tube, and a pair of inner flaps are respectively provided on the front and rear opposite sides of the pair of side plates, and the front and rear opposite sides of the bottom plate and the top plate overlap the inner flaps and the pair of side plates have. A wrap round type outer box provided with a pair of upper flaps or lower flaps each having a length of less than half the width, wherein an opening cutting line is formed on the boundary line between the top plate and the connecting margin. , With respect to the upper flap and the lower flap, a breaking line for unpacking is formed so as to form a C-shape or an inverted C-shape, respectively,
Further, the inner flap and the upper and lower flaps are fixed to each other via a point adhesive portion on the outer side of the breaking line of the C-shape or the inverted C-shape.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an example of an embodiment will be specifically described with reference to the drawings. FIG. 1 shows the state of the case of the present invention when the top surface glue margin is opened, and FIG. 2 shows the state after unpacking. FIG. 3 is a development view of the wrap round case adopted by the present invention. FIG. 4 shows the conventional unpacked state.

In the developed view of FIG. 3, reference numeral 1 is a rectangular bottom plate, 2a and 2b are a pair of side plates provided on the left and right opposite sides of the bottom plate. Reference numeral 3 is a top plate of the pair of side plates that is connected to the side plate 2b. As shown, this top plate is formed to have the same size as the bottom plate. Code 4
Is a connection margin formed in a narrow width connected to the top plate. The connecting margin is a bottom plate 1, a top plate 3, and a pair of left and right side plates 2.
Reference characters a and 2b are for connecting in a rectangular tubular shape.

Also in FIG. 4, the pair of side plates 2
A pair of inner flaps 5a, 5a and 5b, 5b are provided on opposite sides of a and 2b, respectively. Lower flaps 6a, 6a and upper flaps 7a, 7a are provided on opposite sides of the bottom plate 1 and the top plate 3, respectively. These upper and lower flaps are formed to have substantially the same length, and as will be described later, at the time of assembly, the inner flap 5a,
Overlap 5b. The upper and lower flaps are set to have a length that is less than half the width of the pair of side plates.

Further, on the boundary line between the top plate 3 and the connecting glue margin 4, an opening cutting line (referred to as glue margin zipper) 8 made of perforations or zippers is engraved, and the upper flap 7a. And unwrapping break line 9a, 9b or 1 made of perforations or zippers so as to form a C-shape or an inverted C-shape with respect to the lower flap 6a.
Mark 0a and 10b.

The case of the present invention constructed as described above is formed by die cutting a base paper such as double-sided corrugated board or double-sided corrugated board, but in terms of development figure, there is almost no difference from the conventional wrap round case. Therefore, it has good mechanical suitability and is also advantageous for paper removal.

In order to wrap a product g (for example, a small box) using the above wrap round case, first, after placing a plurality of small boxes on the bottom plate 1, the left and right side plates 2a, 2b are attached to the bottom plate. While standing up at a right angle, the top plate 3 is bent in parallel with the bottom plate, and the bottom plate 1, the top plate 3 and the pair of left and right side plates 2a and 2b are assembled into a quadrangular cylinder as a whole. Then, the glue allowance 4 is overlapped on one side plate 2a and spot-bonded.

Next, the inner flaps 5a, 5b are bent inward, and then the lower flaps 6a, 6a and the upper flaps 7a, 7a are placed so as to overlap the inner flaps 5a, 5b.
Fold over. Then, the inner flap and the upper and lower flaps are fixed to each other via the point adhesive portion 11 on the outside of the breaking line 9a, 9b or 10a, 10b for unfolding the C-shape or the inverted C-shape, The package of FIG. 1 is obtained.

By the way, when opening this package,
A tear line (zipper) 10 for unpacking, in which the top surface is peeled off via a zipper margin zipper 8 and then formed on upper and lower flaps.
The a and 10b are cut by pulling them upward to the upper flap and unpacked as shown in FIG.

That is, the contents shown in FIG.
When taking out, the hand is put in the gap between the top plate 3 and the side plate 2a and the top surface is raised upward as shown in FIG. The top plate 3 and the side plate 2b are boundary lines (folds) between the bottom plate 1 and the side plate 2b.
Acts as a hinge, which causes it to rotate like an arrow. At this time, the breaking lines (zippers) 10a and 10b formed on the upper and lower flaps are cut at the same time. In this way, the top and back sides are opened as shown in FIG. In this way, after peeling the glue allowance 4, the top surface and one side surface of the package can be opened with one touch, and the content g can be taken out from the top surface very easily.

Next, when the emptied outer case is crushed and discarded, the breaking lines 9a, 9b for unpacking are cut and the joints between the inner flaps 5a, 5b and the upper and lower flaps 6a, 7a are cut. Detach. In this way, the inner flap 5a,
Since 5b and the upper and lower flaps 6a and 7a are unfolded and laid flat, the package can be collected without being bulky.

[0017]

As described above, the case of the present invention is
Not only does it have good paper picking and machine suitability, but the top surface and one side surface of the package can be completely opened with a single touch via the zipper margin zipper when unpacking. Furthermore, if the break lines for unpacking formed on the upper and lower flaps are broken after the contents are taken out, the packaging case can be easily flattened and the entire case can be expanded flatly, so the case is flatly crushed. The post-treatment (disposal) is significantly superior to the conventional ones because it can be omitted and can be collected without being bulky.
