Description

[Detailed description of the invention] The present invention relates to a paper box with a handle, and in particular to a paper box with a handle that is assembled using cardboard, cardboard, etc., and the handle is formed integrally with the main body of the box. It does not protrude from the top surface, and the area around the handle is strong enough to withstand the weight of stored items, and is configured to be stackable.The external shape is as shown in the perspective view of Figure 1. There is no difference in appearance from the conventional one.

Conventionally, in paper boxes such as this, where the top surface is on the same plane and the carrier part is recessed into the box body and can be stacked, the lid plate a of the box body A is located at the center of the box, as shown in the explanatory diagram in Fig. 2. It tilted and caved in inside the box body,
The tip of the cover plate a rises up in the center of the box and joins together to form a handle part b, and this handle part b has two parts: a handle part c and an upper edge of the handle part b. There is a notch d, and a notch g is provided in the position where the cover plate b matches the notch d, into which an insertion piece f provided at the leading edge of the reinforcing plate e forming a plane on the top surface of the box body is inserted. , when this insertion piece f is inserted into the notch g, the notch h that engages with the notch d is the insertion piece f.
It is provided at the center upper end of the

The shortcomings of the conventional example shown in FIG. 2 are that the insertion of the insertion piece f into the notch h of the cover plate a is just a simple insertion, and there is no locking mechanism, so the cover plate cannot be easily inserted when the box is lifted. There is no effect on preventing floating of. If the width of the notch h of the insertion piece f is narrowed, the part of the notch d of the handle part b will be damaged, and while being shaken, the area near the notch d will be torn and the cover plate b on the side will be damaged.
Since it is separated (cut between the tip of cut g and the tip of cut d), it is completely useless as a carrying case. Mechanically, it tends to rise above the cut d of the cover plate b, and is pressed down outside the cut d, so if the gap between the cut d and the cut g is narrow, it will easily break. is a matter of course.

The present invention solves such conventional drawbacks, and provides a lid with vertical notches 11 provided at the upper edges of the side plates 5, 7 through the fold line 10, which is wider than 1/2 of the width of the end faces 6, 8. Plates 12 and 13 are provided, and the lid plates 12 and 13 are provided.
A hand piece 15 is connected to the leading edge of the piece through a fold line 14,
A grasping part 16 is provided at the center of the gripping part 16 in contact with the fold line 14, and a tongue piece 17 is provided by cutting from the center of the upper edge of one of the grasping parts 16, and a tongue piece 17 is provided at the leading edge of the holding piece 15 via the fold line 24. A folded handle portion 15' having a shape symmetrical to
, and an insertion piece 21 is provided on the upper edge of the reinforcing piece 19 via a fold line 20, and a holding part 22
An engagement notch 23 having a shape is provided from the upper edge of the reinforcing piece 19, and a folded insertion piece 21' having a symmetrical shape is attached to the upper edge of the reinforcing piece 19 via a fold line 25. The main point is that a matching notch 23' is provided.

FIG. 3 is a developed plan view of the paper box with a handle according to the present invention. Side plates 5 and 7 are provided between fold lines 1 and 2 and between fold lines 3 and 4, and end surfaces 6 and 8 are provided between fold lines 2 and 3 and on the outside of fold line 4 to form side walls. A glue margin piece 9 is formed on the outside.

Two parallel vertical notches 11, 11 are provided on the upper edges of the side plates 5, 7, respectively, through the fold line 10, and lid plates 12, 13 are provided which are wider than 1/2 of the width of the end faces 6, 8. A grip piece 15 is connected to the front edge of the cover plates 12 and 13 via a fold line 14, and a grasping part 16 is formed in the center part touching the fold line 14, and one of the grasping parts 16 is A tongue piece 17 is formed from the upper edge by cutting, and a folding line 24 is inserted at the leading edge of this arm piece 15, and a folded arm part 15' having a shape symmetrical thereto is formed.
In addition, a broken line 18 is provided on the upper edge of the gable sides 6 and 8.
A lid reinforcing piece 19 is formed through the reinforcing piece 1.
An insertion piece 21 is provided on the upper edge of 9 via a fold line 20,
In addition, an engagement notch 23 having a clamping portion 22 is provided from the upper edge thereof, and a fold line 2 is formed on the upper edge of the insertion piece 21.
5 and a folded insertion piece 2 having a symmetrical shape.
1' are provided at symmetrical positions, and an engagement notch 23' having a clamping portion 22' is provided from the upper center edge.

To assemble the paper box with a carrying case of the present invention, first, glue piece 9 is pasted on the back side of gable side 8, and the bottom constituent pieces are assembled to form the bottom in the usual manner.

Next, each hand piece 15 and folded hand part 1
5' inward and stand it up at the center of the stacked box and simultaneously push it down, the fold lines 24, 2
The lid plates 12 and 13 are tilted and recessed toward the center with the top edge 4 being the top edge, and the fold lines 24 and 24 are flush with the top surface of the box body. Next, the insertion piece 21 and the folded insertion piece 21'
are folded inward and inserted into the vertical notches 11, respectively, and the engagement notches 23, 23'
is secured to the inner corner of the bent portion 14 of the hand piece 15 by the clamping portion 22.

In this way, the carrying part becomes quadruple, and the clamping part also becomes double, making the strength extremely high. The doubly erected hand pieces form a quadruple structure from both sides, and both expand into a U-shape inside to support the lid plate, increasing the strength against horizontal shaking, and improving the strength seen in conventional hand pieces. The tearing phenomenon disappeared. Furthermore, since the clamping part is also folded back into a U-shape, there is no chance of damaging that part during packaging.

Note that the lengths of the folded hand portion 15' and the insertion piece 21' do not have to be the same as those of the hand piece 15 and the insertion piece 21, respectively, and may be as short as possible as long as the holding mechanism can function effectively.

Another embodiment has a development plane as shown in FIGS. 5 and 6.

The difference in Fig. 5 from Fig. 3 is that in the folded hand piece 15'', notches x are provided on both sides of the central folded grasping part 16'', which is the folded part.
This is to prevent the portion 1' from protruding inward.

6 is an improved version of the one shown in FIG. 5, and is wider than the grasping portion 16 in which a folded grasping portion 16 at the center of the tip of the folding hand piece 15 is provided with a folding piece y on the folding hand piece 15 with a fold line and a notch. a notch x is provided on both sides thereof, and both outer surfaces of the insertion piece 21 and the folded insertion piece 21' are tapered,
The notches with the clamping part are connected by a thin cut line z of a single blade, and finger holes p are provided at the four corners through the insertion piece 21 and the folded insertion piece 21', so that the bearing part has a six-layer structure, and the clamping part Since the cutout line z is made of a single-piece blade, the clamping is performed firmly, and although it becomes difficult to insert the insertion piece on the end surface during packaging, both outer surfaces have a tapered part t.
Because it is shaped like this, it allows you to escape so that it does not hit the inner wall when you push it out with your hands.

As mentioned above, in the present invention, both the hand piece and the insertion piece are folded back to form a double structure, and the free ends of these pieces open inside the box, allowing them to be held in place. As a result, the locking power has become even stronger. In addition, in the lock structure of the present application, when the box is lifted up with the handle piece 15, the center portion of the lid reinforcing plate 19 is pulled upward and the entire lid reinforcing plate 19 is curved, thereby causing the insertion piece 2
1 and the lower end of the folded insertion piece 21' approach the center, the space in the locking part becomes narrower, and the lower end of the hand piece 15 is securely locked.
When the box is lifted up, the lock is strongly locked to prevent the lock from coming off, and when the box is placed down, the locking force is weakened, allowing for easy insertion and removal of the insertion piece and folded insertion piece. be.
