The present invention relates to a packaging box for accommodating a predetermined article, and more particularly, to a handle integrated packaging box provided with a handle on top of the packaging box of paper material, the handle is integrally formed with the box.

Packaging boxes for accommodating items such as coffee mixes or foods are often used for the reason of ease of manufacture and cost reduction, and most of the packaging boxes are provided in a predetermined portion of the packaging box, preferably at the top to improve portability. Form the handle.

The representative form of the packaging box with a handle on the top can be classified into two types, one of which is a form of temporarily fixing both sides of the synthetic resin handle panel manufactured separately from the paper material on the upper packaging box, for example, Korea Utility Model Applications 1984-6719, 1985-11631, 1986-341, 1988-4845, 1989-7972, 1990-12085, 1991-15533, 1997-15604, etc. Although the technique has been proposed, these techniques must be provided with a plastic handle separately from the paper material, the manufacturing cost increases, as well as the process of assembling the handle is added, and separate the paper and plastic handle when discarded There was an inconvenience to be discharged.

In another form, the handle is removed from the top of the box by removing the handle made of synthetic resin, drilling a handle-shaped hole on the top of the box of paper material, and fixing the perforated cover side upright from the top of the box. A vertically installed form has been proposed, and examples of Korean Utility Model Application Nos. 1992-5471, 1990-2245, 1995-25333, 1996-46, 1998-28779, etc. This prior art has achieved the purpose of cost reduction by eliminating the synthetic resin handle, but there is a problem that the packaging box can not be stacked in multiple layers when the handle is formed, the handle at the product packaging stage before the product shipped Since the customer who shipped the product without forming a part and made a purchase must make the handle, There was a dismissal that left the process to the consumer.

As a more improved type of packaging box that solves the problems of these technologies, Korean Patent Application No. 1993-7001812 has been proposed, "reinforced paper box handle," the structure of the top panel of the packaging box facing each other When folded at a viewing position, the parts overlap, but handle holes are formed on both sides of the panel so that the hands can be inserted into the overlapping sides.

The packaging box of such a structure does not need to form a handle at the packaging stage, but the consumer who purchased it can carry it immediately after purchase without making the handle, but there is a problem that the contents of the packaging box are observed through the handle hole. .

This problem is not only unpleasant to the consumer who purchases the foreign matter such as dust through the handle hole inside the packaging box and pollutes the contents, but also if the contents are small items such as coffee mixes or tea bags (TEA BAG). Another problem is that the contents are leaked out through the handle hole, which leads to limitations in use such as considering the type and size of the contents to be accommodated. Also, only a part of each panel covering the upper part of the box is overlapped. There is a problem that can not hold a heavy weight because of poor durability.

Accordingly, the present invention has been devised to solve the above problems, the present invention is to configure the handle on the upper part of the packaging box in one piece, while the upper part is possible to close the seal to completely seal the inside of the box As it is flat, it is easy to load and can be carried immediately without having to open the handle separately. It can reduce the manufacturing cost and provide a solid handle packing box with a rigid structure to accommodate heavy weight contents. There is a purpose.

In addition, the present invention achieves the above object and at the same time, to minimize the height of the space between the space for the hand and the top cover to close the contents, even if the integral handle on the box can be configured to adjust the overall height of the packaging box Another object is to provide a handle-integrated packaging box.

The present invention for achieving the above object is provided with a first upper cover and a second upper cover which is foldably extended to the upper sides of the four sides of the four-sided wall is closed, the opposite sides are symmetrical, the first upper cover and the second A fold line is provided on either side of the upper cover, and a pair of handle holes are formed in the third upper cover and the fourth upper cover, and a flap that can be bent by a fold line on one side of the support holder. Further provided, and the side refolding line is further provided at a position spaced a predetermined distance from the edge of the first and second upper cover.

 Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in more detail.

1 is a perspective view of the upper cover of the packaging box according to an embodiment of the present invention.

Referring to FIG. 1, a first upper cover 10 and a second upper cover 20 which are bendably extended to an upper end of a closed four-faced wall 1 by folding a deployment sheet having a predetermined shape and being folded by conventional means, It is provided in a symmetrical shape with each other, and the third upper cover 30 and the fourth upper cover 40 are provided in a symmetrical shape with each other.

The extended length of the first upper cover 10 is to cover up to half of the width of the packaging box (the width of the third upper cover or the fourth upper cover) when bent inward from the wall 1, the second upper cover An extension length of 20 extends from the half of the width of the packaging box to the opposite tip, but the second upper cover 20 is provided with a fold back line 21.

The position of the fold line 21 is preferably formed so that the second upper cover 20 is located at half the width of the packaging box when the second upper cover 20 covers the top of the packaging box.

Meanwhile, the extension lengths of the third upper cover 30 and the fourth upper cover 40 are substantially the same as the width (width of the first upper cover and the second upper cover) of the packing box, respectively, and each upper cover The handle holes 32 and 42 which are bisected by the support holders 31 and 41 and are connected to each side of the support holders 31 and 41 are formed in the 30 and 40.

In a preferred embodiment, inside the handle hole 42 of the fourth upper cover 40, a flap 44 having a fold line 43 in contact with the side of the support holder 41 is provided symmetrically.

The packing order of the packing box is as shown in FIGS. 2 and 3.

Figure 2 is a perspective view showing the assembly order of the upper cover of the packaging box according to an embodiment of the present invention, Figure 3 is a perspective view showing the assembly state of the upper cover of the packaging box according to an embodiment of the present invention.

Referring to FIGS. 2 and 3, first, the first upper cover 10 to the fourth upper cover 40 cover the upper part of the wall 1 with the first upper cover 10 and the second upper cover ( 20), it is preferable to fold in the order of the third upper cover 30 and the fourth upper cover (40).

That is, as shown in FIG. 2, when the first upper cover 10 is folded into the packaging box, half of the upper opening of the wall 1 is covered, and then the second upper cover 20 is folded into the packaging box. , All the top openings of the wall 1 are covered.

Thereafter, the third upper cover 30 is folded in the same manner, and then, when the fourth upper cover 40 is folded, the third upper cover 30 is folded as shown in FIG. 3, wherein the third upper cover 30 and the fourth upper cover 30 are folded. The handle holes 32 and 42 respectively formed in the 40 coincide with each other, and the packing of the packing box is completed.

Figure 4 is a cross-sectional view taken along the line A-A of Figure 3, showing a state in which the handle is formed from the packaging box of the configuration as described above.

3 and 4, when the flap 44 formed in the handle hole 42 is folded inward using the fold line 43 formed to be folded in advance, the flap 44 as shown in the lower view of FIG. As the 44 is positioned downward, the first upper cover 10 and the second upper cover 20 are pushed downward, so that a space can be inserted between the third upper cover 30 and the second upper cover 20. Is formed.

At this time, when the flap 44 is completely folded to 180 ° from the first position, the flap 44 is in contact with the lower surface of the support holder 31 of the third upper cover 30, each flap 44 and the support holder ( 31) (41) are overlapped with each other, but the handle is easy to grip because of the thick and thick, and the second upper cover 20 is extended to the length of more than half of the packing box handle hole (32) The inner 42 is not observed through the 42), and the fold line 21 serves to smooth the bend downward while the second upper cover 20 is in contact with the first upper cover 10. .

On the other hand, as shown in the lower side of Figure 4, when the fold line 21 is formed in the half-length position of the second upper cover 20, the first upper cover 10 and the first in the process of forming a handle The second upper cover 20 overlaps and bends into a “V” shape, which is because the space in which the fingers can be placed has an inverted triangle shape, so that the refolded portion of the second upper cover 30 is formed on the lower surface of the third upper cover 30. Since the height H up to the tip position of the first upper cover 10 is large, the overall height of the packaging box must be increased or the amount of the contents 50 accommodated in the wall 1 can be reduced.

Therefore, it is preferable to reduce the size of the height (H) in the same structure as the structure to form a handle, the packaging box of such a structure will be described with reference to FIGS.

5 is a perspective view illustrating an upper cover of a packaging box according to another embodiment of the present invention, and FIG. 6 is a cross-sectional view taken along line AA of FIG. 5, and the same reference numerals are used for the same parts as the structure of FIG. 1. In the following description, detailed description of the same parts is omitted.

Referring to FIG. 5, a feature according to another embodiment of the present invention is the same as that of the structure of FIG. 1 in which the first upper cover 10 to the fourth upper cover 4 are extended on the top of the four-faced wall 1. In the packaging box, side fold lines 11 and 22 are further formed on predetermined portions of the first upper cover 10 and the second upper cover 20, respectively, and the side fold lines 11 are respectively formed. The preferred installation position of 22 is satisfied if it is within the range from the lower end of each top cover 10, 20 to half the width of the packaging box.

According to the above configuration, when the flap 44 is folded to form a handle after sequentially covering the first upper cover 10 to the fourth upper cover 40, the first as shown in FIG. The side refolding line 11 of the upper cover 10 and the side refolding line 22 and the refolding line 21 of the second upper cover 20 are bent in opposite directions, and thus the third upper cover 30 An inner space of an approximately trapezoidal shape is formed at the bottom.

Therefore, in the packaging box as illustrated in FIG. 5, the height H ′ from the lower surface of the third upper cover 30 to the tip of the first upper cover 10 or the refolded portion of the second upper cover 20 is Since the height H of the structure of FIG. 1 is smaller than the height H, that is, the condition of H> H 'is satisfied, the structure of the embodiment of FIG. 50) more, and if you want to put the contents in the same quantity, the embodiment structure of Figure 5 can reduce the overall height of the packaging box than the embodiment structure of FIG.

Meanwhile, the handle holes 32 and 42 may be manufactured in various shapes, but are preferably formed in an elliptical shape as shown.

The oval-shaped handle holes 32 and 42 have no angled portions, such as rectangular holes, so that there are no vulnerable areas to tear, and the contents 50 accommodated in the wall 1 are heavy. Even if the elliptical handle hole (32) 42 evenly receives the entire force on the entire inner surface of the third upper cover 30 and the fourth upper cover 40 can be uniformly distributed by the force to be supported, so the designer The handle holes 32 and 42 to allow the load of the contents to be uniformly distributed and supported to the lower ends of the third upper cover 30 and the fourth upper cover 40 according to the weight of the contents contained in the packing box. ) You can adjust the elliptic curve of the enemy.

According to the handle-integrated packaging box according to the present invention as described above, by simply bending the flap formed on the top of the hexahedral packaging box through the handle hole formed in the third and fourth upper cover, the flap and the two-layered support holder overlap each other. Since the handle is completed, there is an advantage in that a handle having a simple and robust structure is formed, and even though the handle hole has a handle hole, the first and second upper covers block the handle hole and the contents so that the contents are not exposed and are completely closed. There is no fear of contamination or spillage.

In addition, the handle of the synthetic resin is excluded, as well as the structure that minimizes the height between the first and second upper cover for sealing the contents and the space where the hand can enter through the handle hole does not significantly increase the overall height of the packaging box Therefore, it is possible to reduce material costs, and further manufacturing costs.
