Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to a packaging box comprising a container body having an open upper surface and a lid body fitted and attached to the open upper surface of the container body. It relates to an improved structure.

<< Prior Art >> A packaging box including a combination of a container body having an open top surface and a lid body fitted and attached to the opening top surface of the container body is well known.

Then, the lid of the packaging box that has been conventionally used is provided by vertically arranging the side plates on the peripheral edge of the top plate having a planar polygonal shape and connecting the adjacent side plates to each other to restrain mutual free movement. The shape is fixed and stabilized.

<< Problems to be Solved by the Invention >> According to the above-mentioned conventional technology, the following problems were caused by the fixed shape of the lid.

Usually, the packaging box is manufactured by punching and assembling paper by a container manufacturer, and is often shipped to users with the container body covered with a lid.

A trader who uses this packaging box fills the packaging box with contents such as a coffee set and sells it to the final consumer. In the packaging box, the container body is covered with the lid as described above. Since it is delivered in a state, it is necessary to remove the lid from the container body when filling the contents.

However, the lid is fitted and attached to the container body, and if the lid is fitted deeply near the bottom of the container body, first there is no place to reach, and secondly when the lid rises. Along with this, the inside of the container body becomes a negative pressure, so it takes time and force to remove the lid.

The boxing work is generally performed by a flow work, and if it takes a long time to remove the lid from the container body, the work efficiency of the entire line is deteriorated, and there is a problem that wasteful cost is increased.

<Means for Solving the Problem> In order to solve such a problem, the present invention is configured by vertically arranging a container body having a flat polygonal shape with an upper surface opened and a side plate hung on a peripheral edge of a top plate and fitted to the container body. The present invention provides a packaging box which is composed of a combination with a lid to be adhered and which satisfies the following requirements (a) to (c).

(A) The side plate of the lid is continuously provided in a bendable state with respect to the top plate, and the edges of the adjacent side plates are in contact with each other in the assembled state, (b) the lid Is provided with a folding plate connected to at least one of a pair of side plates adjacent to each other located at one corner, and the folding plate is slidably sandwiched inside the other side plate. A side plate having a plate is tiltable, and (c) a gap is formed between the side plate and the side plate of the container body in a state where the side plate is tilted.

Further, it is more effective if the folding plate is provided with a stop portion that restricts the tilting range of the side plate.

<< Operation >> When the lid is removed from the container body, first, the side plate having the folding plate is tilted. As a result, a gap is formed between the container body and the side plate, so that the side plate can be easily handled, and the phenomenon that air easily enters the container body through the gap and negative pressure is reduced, and the container body is closed. Is easy to remove.

In addition, if the folding plate is provided with a stopper that restricts the tilting range of the side plate, the folding plate will not be disengaged from other side plates even if the side plate is pulled too much, so that workability is further improved.

<< Embodiment >> An embodiment of the present invention will be described below with reference to the drawings.

 1 to 5 show the first embodiment.

FIG. 1 is a development view of the lid body 1, in which the broken line represented by a thin line indicates a fold curve.

The lid 1 is formed by punching out a double-faced cardboard.

The top plate 2 of the lid 1 is a container body 3 (second
It is formed in a rectangular shape that is slightly larger than that shown in FIG.
Side plates 5a, 5b, 5 are provided on the periphery of the top plate 2 through folding curves 4, 4 ,.
c and 5d are connected in series. The height of each of the side plates 5a, 5b, 5c, 5d is slightly lower than the height of the container body 3, and the side plates 5a, 5b, 5c, 5d are fitted deeply into the upper surface of the opening of the container body 3.

Fold-up pieces 7a, 7b, 7c, 7d are connected to the side plates 5a, 5b, 5c, 5d via two parallel folding curves 6, 6 ,. Further, sandwiching pieces 9 and 9 are continuously provided on both sides of the folding and folding pieces 7a and 7c through folding curves 8 and 8 and the L-shaped cut 1 is formed at the tip of the folding curve 8.
0,10 ... are formed. Further, projections 11, 11 ... Are formed on both sides of the folding and stacking pieces 7b, 7d by notching the base portion close to the folding curve 6, and when the lid body 1 is assembled as shown in FIG. The protrusion 11 and the L-shaped notch 10 are engaged with each other.

The side plates 5b, 5c, 5d are connected by corner bending pieces 12, 12 provided at the corners of the top plate 2. The corner bending pieces 12 and 12 are connected to the side plates 5b, 5c and 5d through folding curves 13 and 13, and folding curves 14 and 14 are formed in the center thereof.

On the other hand, the side plates 5a, 5b, 5d are a pair of adjacent side plates 5a, 5d.
b and 5a and 5d are not connected. That is, as shown in FIG. 1, a member similar to the corner bending piece 12 is present in the corner portion of the top plate 2, but this member is separated by the cut line 15 at the center and the side plate 5a. The members that are continuous to each other through the folding curve 16 constitute the folding plate 17, and the side plates 5b, 5d
A member which is continuous via a folding line 18 constitutes a corner bending piece 19.

The folding plate 17 and the sandwiching pieces 9 that are connected to the folding and stacking piece 7a have end edge shapes that are linear stopping portions 20 that are continuous with the folding curve 6 and arcuate portions 21 around the corners of the top plate 2. Consists of.

 Next, a process of assembling the lid 1 will be described.

First, as shown in FIG. 3A, the side plates 5a, 5b, 5c, 5d are erected along the folding curves 4, 4, .... At this time, the corner bending pieces 12, 12, 19, 19 are bent from the folding curves 13, 18 toward the inside of the lid 1 and in contact with the side plates 5b, 5d. Similarly, the folding plate 17 is also bent so as to come into contact with the corner bending piece 19.

Next, as shown in FIG. 3B, the folding pieces 7a, 7c of the side plates 5a, 5c are bent inward from the folding curve 6 and folded on the inner surfaces of the side plates 5a, 5c. At this time, the sandwiching pieces 9, 9 ... Are also bent at the folding curve 8 and folded on the corner bending pieces 12, 12 and the folding plates 17, 17.

Finally, the folding pieces 7b, 7d are folded on the side plates 5b, 5d and the protrusions 11 are engaged with the L-shaped notches 10 to form the lid body 1 as shown in FIG.

The lid body 1 formed in this way has a side plate 5a and side plates 5b, 5
Since d is not connected, if the hand is put on the edge of the side plate 5a and pulled outward, the side plate 5a is centered around the folding curve 4 and the side plate 5a is shown in FIG. 2 (b), FIG. 3 (d) and FIG. 4 Tilt as shown by the chain line. In addition, since the linear stop portion 20 is formed on the end edge of the folding plate 17 as described above, this serves as a stopper and normally the side surface plate 5a is stable without tilting. When a certain amount of force is applied to 5a, each part is appropriately deformed and the stopper 20 is easily tilted out of the gap between the side plates 5b, 5d and the folding pieces 7b, 7d.

FIG. 6 is a development view of the lid 1 showing the second embodiment. In the first embodiment, the folding plate 17 and the corner bending piece 19 are completely separated by the score line 15 from the stage before assembling the lid body 1, but if this is done, the workability of assembling the lid body 1 deteriorates. There is a risk. On the other hand, in the second embodiment, a slightly perforated line 22 is formed at the tip of the cut line 15, and the folding plate 17 and the corner bending piece 19 are temporarily integrated at the stage of assembling the lid 1. This improves the workability of the assembly work. Then, in order to tilt the side surface plate 5a, an outward force may be applied to the side surface plate 5a as described above. Then, the sewing machine wire 22 is broken, the side plates 5a, 5b, 5c, 5d are uncoupled, and the side plate 5a becomes free and tilts in the same manner as described above.

FIG. 7 shows a third embodiment, and is a development view of the lid 1 with a part enlarged. In this third embodiment, the shape of the edge of the folding plate 17 is improved, and linear stopping portions 20A and 20B are formed at both ends of the folding plate 17. And stop 20A
Is for stabilizing the form of the lid 1 as described above, and the stopper portion 20B has a function of restricting the tilting range of the side surface plate 5a. The folding plate 17 does not come off between the side plates 5b and 5d due to the restraining portion 20B.

FIGS. 8, 9 (a) and 9 (b) show the fourth embodiment, and disclose a restraining portion 20C having a structure different from that of the restraining portion 20B of the third embodiment.

As shown in the development view of FIG. 8, the restraining portion 20C is a belt piece formed on the upper edge of the corner bending piece 19 by bending the score line 15 toward the corner bending piece 19 side from the middle. 23. A plurality of folding curves 24, 24 ... Are formed on the belt piece 23 in the direction toward the corners of the top plate 2.

In the lid 1 of the fourth embodiment, the corner bending piece 19 and the folding plate 17 are connected by the belt piece 23, so that the assembling work is easy as in the second embodiment. Then, when the edge of the side plate 5a is pulled slightly outward to tilt the side plate 5a, the folding plate 17 pulls the belt piece 23. Then, the belt piece 23 bends one after another from the folding curves 24, 24 in a state where the caterpillar moves, and follows the folding plate 17, and the side plate 15 tilts as shown in FIG. 9B. Then, the tilting of the side surface plate 5a stops when the belt pieces 23 are all inverted.

The belt piece 23 includes the side plate 5b (5b) and the folded piece 7b.
Since it follows the movement of the folding plate 17 while changing the direction by 180 degrees in the limited gap with (7d), the folding curve 2
The smaller the intervals of 4, 24 ..., the easier it is to invert and the easier movement of the folding plate 17, and conversely, the wider the intervals, the more difficult it is to invert and the difficulty of moving the folding plate 17. Utilizing this property, in the fourth embodiment, as shown in FIG.
The state where the side plate 5a is not tilted by widening the interval from the boundary between the corner bending piece 19 and the first bending line 24 and narrowing the interval between the second and subsequent folding lines 24. In addition to improving the morphological stability, the side plate 5a moves smoothly once the side plate 5a starts to move.

The strength of the belt piece 23 can be adjusted by changing the height of the belt piece 23. Therefore, the lid 1
The height may be set appropriately according to the material forming the.

The first to fourth embodiments have been described above,
It goes without saying that the present invention is not limited to the configuration of each of the above embodiments.

For example, the folding plates 17 may not be provided on both sides of the side plate 5a, but may be provided on only one of the side plates 5a. In this case, it is desirable to make appropriate markings so that the tiltable corners are clear.

Further, the folding plates 17 may be provided on the side surface plates 5a and 5c so that both side surface plates 5a and 5c can be tilted.

Furthermore, the folding plates 17 may be provided at one position on each of the side plates 5a and 5c so that the side plates 5a and 5c can be tilted with respect to the corner portions of the top plate 2 located on the diagonal lines. In this case, since the tiltable portion around the center of the top plate 2 is point-symmetrical, the tiltable corner portion can be easily understood without providing the above marking.

<Effect of the Invention> As described above, according to the packaging box of the present invention, since a part of the side plate of the lid can be tilted, the side surface of the container body and the lid body when the lid body is removed from the container body. Gaps can be provided between the plates. Therefore, even if the container body and the lid are fitted deeply, it is easy to put a hand on the side plate of the lid, and it is easy for air to enter the container body through the gap, resulting in a negative pressure inside the container body. It has the effect of softening and making it easier to remove the lid from the container body.

In addition, if the folding plate is provided with a stopper that restricts the tilting range of the side plate, the folding plate will not come off from the other side plate even if the side plate is pulled too much. Will be easier and the workability will be improved.
