Description

  The present invention is used for a step-folding container, more specifically, for expanding to separate and organize goods etc. and tilting and displaying so as to be easily viewable by a buyer, and also convenient for transportation and storage. The present invention relates to a step-folded container which can be folded into a flat plate shape and which can be repeatedly expanded and folded without any wear and tear.

  In this specification, bending or pasting a cut sheet so that it can be made into a box by one touch is referred to as "assembly" and making the assembled into a box is called "expansion" or "setup". In other words, it is called "folding" to squeeze a flat thing that has no contents into a flat shape.

Conventionally, when arranging and arranging products with a display shelf, a display showcase, etc., the remaining part of a corrugated cardboard box opened by placing it in a rack with bare, using a tray, removing a lid and opened is the same as the tray It is used to
In the case of exposing the goods directly to the display shelf, it is difficult to move adjacent other goods by taking out the goods, it is difficult to maintain the alignment of the goods, and furthermore, it is difficult and difficult to rearrange the goods.
The tray has a low peripheral side wall, which may cause the goods etc. to slip out of the tray or the stacked goods may collapse. On the other hand, trays with high side walls have the problem of being inconvenient for transporting and storing the trays.
The box for removing and opening the lid is generally disposable, which is not only waste of resources but also causes a problem of waste disposal.

  Similar to a box which is opened by removing a lid, there is also a container made of a synthetic resin which can be expanded, assembled, folded, disassembled and the like. However, molding of a synthetic resin requires a molding die which requires high manufacturing cost for each component, and the fact is that it is not used for a small number of manufacturing due to the problem of manufacturing cost. Therefore, it is desirable to form a small number of boxes by using cardboard or corrugated paper and by cutting and pasting them, since it is possible to easily carry out display and promotion suitable for the problem of manufacturing cost and fashion.

  A paper box having a bottom structure described below has been proposed as a container formed by cutting using cardboard or corrugated paper. That is, as shown in FIG. 13, it is a paper box in which the side faces 401 and 402 and the end faces 403 and 404 constituting the box are alternately connected, and the side faces 417 to 420 of each end face and the end face are connected. Bottom surface components of the two side surfaces are half bottom plates 417 having a width equal to or less than a half width of the bottom surfaces of the end surfaces, and the other bottom components are all bottom surfaces plates 418 covering the entire bottom surfaces. Is substantially trapezoidal, and each bottom plate is partially adhered to the adjacent half bottom plate 417 or the entire bottom plate 418 to form a bottom lid, and a portion of the bottom plate to be bonded to the entire bottom plate 418 is further extended There has been proposed a bottom structure of a paper box in which 419b, 425 are formed, and a cut for relief 426 is provided in the extension base of the bonding portion (see, for example, Patent Document 1). The entire bottom plate 418 has a fold 418a (not shown).

  In addition, in order to maintain a state in which the extension portion or the like of the side surface of the folding container is folded back to a predetermined position, a configuration is also proposed in which a projection is provided at the tip of the extension portion and the projection is inserted into a groove provided in the lower end of the side surface. (See, for example, Patent Document 2).

Japanese Utility Model Publication No. 57-180617 Japanese Patent Application Laid-Open No. 10-45122

  In the paper box proposed by Patent Document 1 and the like, referring to FIG. 13, adhesive portion 419b does not extend to the boundary ridge line between side surface 401 and half bottom plate 417, and adhesive portion 425 has side surface 402 and the entire bottom. It does not extend to the boundary ridge line with the face plate 118, and the durability as the bottom of the half bottom plate 417 and the total bottom plate 418 is low. Therefore, this paper box is unsuitable as a container for storing a bottle or the like filled with a liquid or a container for storing an object having a large specific gravity. That is, when a heavy item is accommodated in the box, the bottom plate portion may be distorted downward, the adhesion may be peeled off, and the so-called underside may occur.

  The paper box proposed by the patent document 1 etc. is provided with the cut 426 for rigidity relaxation in the extension base of the adhesion part as mentioned above. However, when the collapsing container is expanded from the folded state and assembled, the entire bottom plate 418 tries to return to the folded state by exceeding the pulling force of the bonding portion 425, that is, the whole bottom plate 418 tries to lift up. Power remains. As a result, it is necessary to immediately put a heavy object in the folding container after expansion, or to manually push down the entire bottom plate 118 or the like. The propensity of lifting the bottom plate is that, when a light object is placed in the folding container, the bottom portion is lifted and inclined, resulting in the disadvantage that the contents aligned on the bottom plate may fall over or scatter. . The same problem occurs when the product is first put on the lifted bottom plate.

  The paper box proposed by the above Patent Document 1 etc. is further provided with an inclined step in the paper box to accommodate and incline the storage towards the purchaser instead of laying flatly so that the purchaser can see the contents well. There is a problem that the container is not placed, and the lightweight stepping member is lifted from the predetermined position, and contents such as goods become irregular on the above-mentioned stepping member.

It has a second long side surface portion C and a second short side surface portion D of the same shape and size as the first short side surface portion B.
The first long side surface A, the first short side surface B, the second long side surface C, and the second short side surface D are formed by aligning a plurality of vertically elongated vent holes L.
At an end opposite to the first short side surface B of the first long side surface A, a side margin M to be attached to the second short side surface D is formed.

The first long side surface portion A has a lower long bottom surface portion F extending from the first lower side 1 thereof. The second long side C has a rectangular upper long bottom E extending from the second lower side 102 thereof.
The first short side surface portion B has a trapezoidal first short bottom surface portion G extending from the third lower side 103. The first short side surface portion B also has a rectangular display surface portion Q extending from the third upper side 111 opposite to the first short bottom surface portion G. The display surface portion Q displays a trademark of the stored product P which is a product or the like, a sales promotion catch phrase, and the like. The second short side surface portion D has a trapezoidal second short bottom surface portion H extending from the fourth lower side 104.

The first short bottom surface portion G extends in the direction from the first folding line 112 to the lower long bottom surface portion F via the first folding line 112 which is inclined 45 ° with respect to the third lower side 3 of the first short side surface portion B Have a first margin J.

  The upper long bottom portion E has a protrusion 105 at its tip. The protrusion 105 is inserted into the groove 110 provided in the second lower side 2 at the time of expansion.

The first margin J has a first cut 122 which is recessed from the end side 124 on the lower long bottom portion F side in the extension direction of the third lower side 3 and is formed along the first folding line 112.
The second margin K has a second cut 126 which is recessed from the end 120 on the upper long bottom E side in the extension direction of the fourth lower side 4 and is formed along the second folding line 114.

The upper long bottom portion E has a reinforced mountain fold line 116 extending from the first intersection point 130 of the second lower side 102 and the first boundary side 106 in a direction away from the second short bottom portion H toward the tip. The first boundary side 106 is a boundary between the second long side surface portion C and the second short side surface portion D.
The lower long bottom portion F is cut along a straight line extending in the direction away from the first short bottom portion G as it goes to the tip from the second intersection point 134 of the first lower side 101 and the second boundary side 107. The second boundary side 107 is a boundary between the first long side surface portion A and the first short side surface portion B.

(assembly)
In the upper long bottom portion E, the folded portion N on the second short bottom portion H side is folded back so that the reinforced folding line 116 shown in FIG.

  Next, apply paste to the front or back of the side seal M. Apply paste to the entire back surface of the first paste J and the second paste K in FIG.

  Next, as shown in FIG. 3 to FIG. 6, the surfaces coated with the adhesive pastes of the side surface coverage M, the first surface coverage J and the second surface coverage K are respectively the second short side surface D, the upper long bottom surface E and the half. It is stuck on the surface in FIG. 1 of the long bottom portion F.

(Folding and spreading)
When the folding container in the state shown in FIG. 3 and FIG. 4 assembled as described above is pushed from the left and right direction in the drawing to reduce the dimension in the left and right direction, the first short bottom surface portion G is lowered through the first margin J. Pull down the long bottom F. In addition, the second short bottom portion H pulls down the upper long bottom portion E via the second edge K. As a result, as shown in FIGS. 5 and 6, the container can be used in a deployed state.

As shown in FIGS. 2 and 3, since the folded portion N is provided, no frictional resistance is generated between the upper long bottom surface portion E and the second short side surface portion D in this stretching operation, and the stretching can be prevented. There is nothing to do. Furthermore, since the lower long bottom portion F is cut along a straight line extending from the second intersection point 134 of the first lower side 1 and the second boundary side 107 in a direction away from the second short bottom portion G toward the tip. The frictional resistance does not occur between the lower long bottom surface portion F and the first short side surface portion B, and the expansion is not hindered.
Finally, the full length bottom portion E is pushed downward, and the projection 105 of the full length bottom portion E is inserted into the groove 110.

  As a result of this expansion, the bottom of the folding container 100 has the upper long bottom E and the half long in addition to the attachment of the first edge J and the lower long bottom F and the attachment of the second edge K and the upper long bottom E. The long bottom portion F sandwiches the folded portion N continuous with the upper long bottom portion E. Therefore, the bottom of the folding container has a high rigidity and a high durability. Even if a heavy load is stored, the risk of the bottom being pushed down and deformed is reduced.

  On the other hand, since the protrusion 105 of the upper long bottom portion E is inserted into the groove 110, the amount of stored matter decreases and the load on the bottom portion is lightened, or even if the load becomes zero, the upper long bottom portion E is predetermined. Maintain a horizontal flat state of This configuration not only enables efficient replacement of the contents, but also has the great advantage that the contents can always be kept in a consistent state on a stable horizontal surface.

  When carrying or storing unfolded containers, fold them. Folding folds the inner bottom fold line 116 up and lifts the protrusion 105 out of the groove 110. In this operation, the full length bottom surface portion E is lifted so as to swing around the first lower side 1. Then, it squeezes in the up-down direction in FIG.3 and FIG.4.

  At the time of this folding, since the first margin J is recessed from the end side 124 on the lower long bottom portion F side in the extension direction of the third lower side 3 and has a notch 122 formed along the first folding line 112, The bottom corner portion where the lower long bottom portion F and the first short bottom portion G exist can be easily folded without the sheet being excessively folded.

  In addition, since the second margin K is recessed from the end side 120 on the lower long bottom portion F side in the extension direction of the fourth lower side 4 and has a cut 126 formed along the second folding line 114, the lower length The bottom corner portion where the bottom portion F and the second short bottom portion H exist can be easily folded without the sheet being excessively folded.
