Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a carton with a handle having an upper opening stuck and closed.

<Prior Art> Conventionally, a carton with a handle of this kind has a top plate which is aligned with the upper sides of the side plates (31) and (32) facing each other at the center of the upper opening as shown in FIG.
(33) and (34) are installed in a row, and the handle parts (35) and (36) are installed on the top side of the top plates (33) and (34), and the top plates (33) and (34) are installed inside. Fold it over the flaps (37) and (38) and attach it to the top plate (33) and (3
4) The upper parts of the handle parts (35) and (36) were made to stand up in a state where the upper parts of the upper part were matched.

<Problems to be solved by the invention> However, the above-mentioned conventional carton with a handle has one top plate (34).
Since the holding piece (39) of the other must cross the other handle (35), it cannot be pasted with a normal machine when closing the upper opening after storing the product, so whether it should be attached manually. However, there is a problem that a dedicated machine is required, work efficiency is low, and cost is high.

Therefore, the present invention provides a carton with a handle that can be formed by a simple combination of two folding operations and has good mechanical suitability.

<Means for Solving Problems> The present invention has been made to solve the above problems, and an upper top plate is provided on one side plate upper side of a pair of facing side plates.
A lower top plate is continuously provided on the upper side of the other side plate, and the upper top plate has a sticking portion that extends to both sides at the upper end through a notch connecting the folding line and the inner end of the folding line to obtain a handle hole. A possible handle portion is provided, and a handle hole is provided by cutting out at a position symmetrical to the handle hole, the handle portion is folded in two, and the attaching portion is attached to the back surface of the outer top plate, and then the inner top plate is attached. The outer top plate is folded and adhered on the top.

<Examples> The present invention will be described in detail with reference to the drawings. FIG. 1 is an exploded plan view showing side plates (1), (2), (3), and (4) that are sequentially connected through a fold line to form a rectangular tube-shaped body and opposite side plates.
Outer top plate (5) with a fold line on the upper side of one side plate (2) of (2) and (4)
The outer top plate (5) has a fold line (l ₁ ) in the center on the upper side of the outer top plate (5), and a sticking part (13) protruding to the same position as the upper end of the outer top plate (5) at the upper end. Handle part formed through the fold line (l ₂ ).
(9) is provided through a fold line (l ₂ ), (l ₂ ) and the fold line (l ₂ ), (l ₂ ) through an inverted U-shaped cut connecting both ends, and a handle hole (11) obtained by this cut is provided. ), The handle hole (12) is provided by cutting out. In the figure, 10 is a pressing piece, which is formed to project at the tip of the outer top plate (5) corresponding to the handle hole (11). Also, the inner top plate (6) is connected to the upper side of the side plate (4), and the inner flaps (7) and (7) are connected to the upper sides of the other facing side plates (1) and (3) through a folding line. The bottom flap (1
3), (14), (15) and (16) are arranged in series.

Furthermore, a locking projection (17) is provided at the tip of the inner top plate (6) and a locking notch (18) is provided at the outer top plate (5), and a zipper and a sewing machine are provided above the locking notch (18). Cutoff line of eyes etc. (1
9) is provided.

To assemble the present invention having the above structure, the side plate
Bend (1), (2), (3), (4) along the fold line, and side plate (4)
The seam part (20) formed at the open end is attached to the inner surface of the side plate (1) to form the body part into a rectangular tube shape, and the handle plate (9) is broken line (l ₁ ) at 2
Fold it in half to connect the handle hole (11) with the handle hole (12), align the fold line (l ₃ ) with the fold line (l ₂ ), and attach the attachment part (13) at the upper end to the back of the outer top plate (5). Stick it on. This step can be box-made with a normal sack applicator.

In addition, the bottom flaps (13), (15) on the outside of the bottom flap
(14) and (16) are folded and attached, and the bottom is closed. The product is stored in this state, and the inner flap is inserted as shown in FIG.
The inner top plate (6) and the outer top plate (5) are sequentially folded over (7) and (7), and the inner top plate (6) and the outer top plate (5) are attached to the outer top plate (5). Cutoff line (1
9) Apply adhesive to the upper part and stick it. Also in this process, ordinary products can be bonded to each other by a sealing machine continuous to the filling line. The halftone dots in the figure are adhesive parts.

In the present invention assembled in this way, the handle part (9) is broken line.
It can be bent up and down freely with (l ₂ ), (l ₃ ), and when carrying it, it is enough to stand the handle plate (9) vertically, and as shown in Fig. 3, fold the handle part (9) horizontally. Since the handle portion (9) is at the same height as the outer top plate (5) in this state, only the handle does not project on the top plate unlike the conventional one, and the stacking characteristics are good. When opening, it is sufficient to break the cutoff line (19), and after opening, engage the locking protrusion (17) of the inner top plate (6) with the locking notch (18) of the outer top plate (5). Can be easily resealed.

<Effects of the Invention> As described above, according to the present invention, the handle can be assembled simply by folding the handle in two and attaching it. Therefore, the handle is automatically attached by a conventional sack pasting machine, a filling and sealing machine, or the like. Therefore, the manufacturing cost can be reduced and the assembling work efficiency can be improved. Moreover, since the upper end sticking portion of the handle portion is projected to both sides, there is no gap between the outer top plate and the inner top plate, and the sealing performance is excellent.
