Description

[Detailed Description of the Invention] This invention relates to a handheld packaging box, and more specifically, to a handheld packaging box made of paper such as cardboard.

Many conventionally known handheld packaging boxes made of cardboard are assembled by folding the base paper along the crease lines formed in advance, and the handles are also formed integrally with the box. There are some that use separate handles, but none of these can be packaged in a hermetically sealed state, and they have the disadvantage that an opening is formed in a part of the box. All parts have the same strength, so when the contents are packaged and handled, the bottom part, which directly supports the weight of the contents, and the top part, where the handles are attached, may break and become unusable. Ta.

Therefore, this idea was developed in a handheld packaging box.
The parts that carry a large load are strengthened to prevent them from becoming unusable due to local breakage.For this purpose, they are assembled by folding a sheet of base paper, and a handle is attached to the bottom part. The structure is characterized in that the upper surface portion is double-layered to increase durability.

Hereinafter, embodiments of the configuration of this invention shown in the attached drawings will be described. First of all, FIG. 1 is a perspective view of the handheld packaging box according to this invention in an unfolded state. It uses a substrate paper cut out by punching cardboard or the like, and the long sides of the rectangular bottom substrate 1 are The side plates 2 and 3 are formed through the fold line 1a, and the side plates 2 and 3 face each other in the assembled state, so they have the same shape. End plates 4, 5 are formed, the width of which is determined to be equal to the width B of the bottom substrate 1.

An upper cover plate 6 is formed on the long side of the other side plate 3 through folds 3a, and can cover the opening of the box when folded, and has a long slot shape in the center. A window hole 6a is formed.

Since the end plates 4 and 5 take positions facing each other, they have the same symmetrical shape, and the fold 2
Folds 4a, 4b, 5a, 5b are on the sides perpendicular to a.
Large flaps 41, 42, 51, 52, which are less than half the size of the bottom substrate 1, are formed through the flaps, and the edges of the end plates 4, 5 parallel to the fold 2a have folds 4c, Small flaps 43, 53 are formed via 5c.

Further, a cover plate 7 having the same shape and size as the upper cover plate 6 is formed between the large flaps 41 and 51 and along the middle section of the side plate 2 via the fold 2b. In the central part of this cover plate 7, when overlapped with the cover plate 6, two window holes 7a are bored at positions corresponding to both ends of the area of the window holes 6a. The large flaps 41, 51 are provided with window holes 41a, 51a which overlap one of them. Adhesive is applied to isosceles triangular portions T of the large flaps 42, 52 near the bottom substrate 1, so that they can be adhesively fixed to the inner surface of the bottom substrate 1 in the assembled state. Semicircular locking windows 6b are bored at appropriate intervals on the free edge of the upper cover plate 6, and two locking metal fittings 7b installed on the fold 2a side of the cover plate 7 are locked. It can be inserted and locked into the window 6b.

Next, the assembly order of the handheld packaging box according to this invention will be explained. First, every part of the fold is subjected to a valley fold operation, and the large flaps 42, 52 are
is positioned inside the bottom substrate 1 and integrated with the bottom substrate 1 with adhesive applied to the isosceles triangular portion T, and is stocked in a flat shape as a whole as shown in FIG. From this state, it is assembled for use, and it is assembled into the state shown in Fig. 3.
The flaps 43 and 53 are valley-folded inward along the folds 4c and 5c. Furthermore, as shown in Figure 4,
After the side plates 2 and 3 are raised to surround the bottom substrate 1 on all sides and the contents are stored through the upper opening, both ends of the handle S are engaged with the window holes 7a and the cover plate 7 is folded. Bend it at the eye 2b, stack it on the large flaps 41, 51, and open the window hole 41 of this large flap 41, 51.
a, 51a, and locking pieces at both ends of the hand S.
Lock S ₁ and S ₂ . Then, the upper cover plate 6 is placed on top of the cover plate 6, the handle S is made to look through the window hole 6a, and by grasping and lifting the handle S, the entire packaging box can be lifted.

Therefore, the large flaps 41 and 51 are stacked on the bottom substrate 1, which bears the weight of the contents, and the portion to which the handle is attached is triple-layered, consisting of the large flaps 41 and 51, the cover plate 7, and the upper cover plate 6. In particular, the load caused by the hand S is borne by three sheets of material.

As is clear from the above description, the handheld packing box of this invention has two side plates provided to the bottom substrate, and one side plate has end plates formed on both sides thereof.
Large flaps are provided on both sides of the end plate, and a cover plate with a window hole for locking the locking piece of the handle is formed on the side plate, and it is configured to be assembled by valley-folding.
The bottom part has a double bottom, and the part that locks the handle is a triple plate, so there is no chance of the bottom falling out or the handle falling out when the bag is hung, and the contents can be hidden from the outside.
