BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates mainly to paper packaging containers such as paperboard, and more particularly to a carton excellent in resource saving, recyclability and foldability.

[0002]

2. Description of the Related Art Hitherto, there has been a case where a package formed by integral molding of a synthetic resin has been used for packing a powder or a granular state. However, so-called refuse disposal after use is costly, and further cost is required for reuse. In addition, even when buried in the ground, it may not be corroded, and in some cases, may be accompanied by generation of toxic gas, and there is also a problem that it is sold or collected by the manufacturer itself.

[0003] In recent years, containers made of paper, such as paperboard and corrugated cardboard, have become widespread so that they can be collected and recycled through general routes. However, another problem has arisen when collecting containers. In other words, after use, it is difficult to deform into a flat state that is excellent in effective use of space,
The processing time has become troublesome.

[0004] However, in order to easily transition to the flat state, it is necessary to use a large number of folded lines. As a result, the strength cannot be maintained when assembled into a box shape, and the reinforcing pieces are arranged inside or the like. It was way. As a result, the amount of paper consumption has increased, and this has gone against resource saving.

FIG. 9 is a perspective view showing an example of the related art.
That is, after assembling into a box-shaped carton 90, the contents are accommodated in a state where the top plate portion is opened, and then the contents are sealed and sealed, and a zipper J provided on the lid portion 91 and the body portion 92 at the time of use is provided.
And the lid 91 and the body 92 are separated from each other except for the hinge portion. After the contents are appropriately measured and used with a spoon or the like, the lid 91 is closed again. For this reason, at the upper end of the trunk portion 92, a difference in plate thickness is provided at a fitting portion 93 between the trunk portion 92 and the lid portion 91 so that the lid portion 91 is covered on the outside.

In order to provide this difference in plate thickness, an inner plate 95 prepared separately is arranged on the inner periphery of the upper edge of the body, and an upper edge 96 projecting from the cut end of the zipper J is formed. ing.
The upper edge 96 is joined to a top plate forming the lid 91.

The inner plate B is a front plate constituting a box,
A single plate material is bent into a rectangular tube shape over the entire inner surface of the back plate and the left and right side plates, and a locking member S such as an eyelet is formed at both side plates.
Together with the band Ba for carrying. In addition, the bottom of the carton 90 includes the front plate, the back plate,
The plate members extending downward from the left and right side plates are each bent and glued together in a four-ply state.

[0008]

In the prior art, the inner plate is disposed over a wide area from the upper end to the lower end of the front plate, the back plate, the left and right side plates, and a step portion at the upper edge is formed. In order to use the paper only, waste of paper is large and resources are depleted.

Further, as described above, means for easily crushing and flattening for convenience during transportation and storage for reuse as post-processing is lacking. desired.

[0010] The present invention is a carton for powder packaging which aims to provide a means for saving resources and easily crushing during processing after use.

[0011]

DISCLOSURE OF THE INVENTION The present invention relates to a carton for powder packaging in which powder, granules, and the like are stored in a rectangular tube-shaped carton using cardboard such as paperboard or corrugated cardboard. A left and right side plate, a front plate, a back plate and a body portion made of glue margin pieces, and a bottom portion made up of an extension of each of the above members and a lid portion made up of each lid plate and a bottom portion made up of each bottom plate, A zipper is formed on the upper edge of the body, a separate inner plate is provided inside the zipper, and a fitting portion having an upper end protruding from the zipper is formed. A packaging carton for powder or the like, characterized in that the inner plate is fixed together with a band for holding by a locking tool.

[0012] The inner plate may be substantially half of the body.
It is characterized by being fixed to the left and right side plates, the front plate and the back plate of the carton, and being fixed to the left and right side plates with eyelets or the like, while the other inner plates are the same as the front plate. The front plate has substantially the same area, and the left and right side plates are in contact with only approximately half the area of the left and right side plates of the carton. The front plate is fixed to the left and right side plates of the carton with eyelets or the like.

[0013]

According to the present invention, after the lid is opened by the zipper, the lid can be covered and closed by the fitting portion formed by the separate inner plate. In addition, since the inner plate is partially disposed instead of the entire surface of the body, resources can be saved by saving materials. Furthermore, by arranging the fold lines on the left and right side plates, it becomes easy to flatten at the time of collection or the like.

[0014]

FIG. 1 is a development view showing one embodiment of the present invention, FIG.
Is a development view of an inner plate similarly prepared separately, FIG. 3 is a perspective view after assembling, FIGS. 4 to 6 are perspective views showing states in use, and FIGS. 7 and 8 are development views showing another embodiment. It is a figure and a perspective view.

The present invention is a carton mainly formed of a cardboard sheet such as a corrugated cardboard or a paperboard for packing powder or granules such as detergents. The carton has a structure which can be easily flattened after use and realizes resource saving. It has a structure.
That is, the external appearance of the invention of the present application is, in principle, a rectangular cylindrical shape, the front side forms a wide side and the left and right sides form a narrow side surface, and an inner plate disposed inside by a locking tool such as an eyelet there. A portable band that is made of recycled plastic and that can be decomposed by microorganisms is fixed. Of course, it is needless to say that not only the synthetic resin but also any known means such as a paperboard folded in two and added to the thickness so as to be easily carried, for example, may be used.

According to the present invention, the rectangular tubular carton is formed as follows. A paper sheet 1 (backing paper) such as a paperboard is appropriately cut to form a developed view shown in FIG. The sheet 1 is not limited to recycled paper, but it goes without saying that if it is recycled paper, resources will be saved. The carton 2 of the present invention will be described with reference to FIG. 1. The carton 2 is constituted by members forming a body A, a cover B and a bottom C. In particular, the cover B and the bottom C have substantially the same shape as shown in the drawing. ing.

That is, in the middle of FIG. 1, the back plate 3, the left plate 4, the front plate 5, the right plate 6, and the adhesive margin 7
It is divided by 9, 10, 11 and fold lines 12, 13.
Further, a lid plate 15 and a bottom plate 16 are provided above and below the back plate 3, a lid plate 17 and a bottom plate 18 are provided above and below the left plate 4, and a lid plate 19, a bottom plate 20 and a right and left plate 6 are provided above and below the front plate 5. Are provided with a lid plate 21 and a bottom plate 22, respectively.

Further, the left side plate 4 has a fold line 23 perpendicular to a position where the length in the short direction is divided into two, and an intersection of the fold lines 9, 13 and the fold lines 10, 13 below the fold line 23. Crossing fold lines 24 and 25 are provided, and fold lines 26, 27 and 28 are similarly provided on the right side plate 6.

Further, a narrow zipper 32 having a pair of cutting lines 30 and 31 disposed on the upper edges of the left side plate 4, the back plate 3 and the right side plate 6 in parallel with the fold line 12 is formed. This zipper 3
2 has a knob 33 at one end.

Further, the sheet shown in FIG. 2 is an inner plate 40, which is arranged so that the upper edge of the body A is in contact with the folding line 12 and the upper end thereof, and at the same time, a hand strap made of recycled plastic. Both ends of Ba are connected to the left and right side plates 4 and 6.
Is fixed by a locking tool S such as an eyelet. Folded lines 41, 42, 43, and 44 are sequentially engraved on the inner plate 40 in the horizontal direction.

To further explain the above-mentioned embodiment, the inner plate 40 is fixed only by the locking member S, and the conventional inner plate formed by arranging a sheet over the entire surface in the vertical direction. In contrast, the upper portion corresponding to the portion of the zipper 32 in which the body portion A and the cover portion B fit is disposed only on the upper portion, thereby forming a step corresponding to the plate thickness at the upper end of the body portion A. The fitting portion I which can fit the portion B to the body portion A is formed so that the lid can be freely closed.

With the above configuration, the present invention is completely sealed in the unopened state, and is formed so that the contents are not solidified by moisture. On the other hand, when opened, the contents can be easily opened by the zipper 32. When sealing, cover B
Is fitted to the inner plate 40 to close the lid B, thereby preventing solidification of the contents.

Further, the inner plate 40 is formed with a small area, thereby saving resources. In addition, since the inner plate 40 is locked by the left and right side plates 4 and 6, the inner plate 40 and the carton 2 are not filled when the product is filled. Even if the product is sandwiched between the members forming the body portion A, the product can be efficiently filled without falling down and causing clogging.

Further, after use, not only the flattening can be easily performed by the folding lines 23 to 28 formed on the left and right side plates 4 and 6, but also the inner plate 40 can be fixed at the locking points by the folding lines 2 of the left and right side plates 4 and 6.
Since only the intersections with 3 and 26 are provided, flattening can be easily performed.

FIG. 7 is a development view showing another inner plate 50. The inner plate 50 has a front plate 51 having substantially the same area as the entire surface of the front plate 3, and the other left and right side plates 52. ,
Numeral 53 is not the same as the left and right side plates 4 and 6 of the carton 2, but is connected to the front plate 51 in an area equivalent to almost half, and is not provided on the rear plate side.

The inner plate 50 has the effect of increasing the strength of the carton 2 in the vertical direction and improving the stacking property during storage and transportation.

[0027]

According to the present invention, the processing cost after use is lower than that of a conventional container formed by integral molding of a synthetic resin, and the operation of folding and flattening for recycling is extremely easy. Since it can be performed, the recycling operation is easy and the cost for recycling is low. In addition, it is a device with excellent features such as cost reduction by mass production by automatic box making and easy resealing at the time of use, and is a device useful for industrial use.
