Description

  The present invention is used for folding containers, and more specifically, for sorting and organizing and displaying products and the like, and can be folded conveniently for transportation and storage. The present invention relates to a folding container that can be repeatedly formed without being worn or destroyed.

  In this specification, folding and sticking a cut sheet to make it a box with a single touch is called "assembly", and making an assembled box is called "stretching" or "setup". In other words, it is called “folding” to squeeze an unfolded empty space to make it flat.

Conventionally, when arranging products on display shelves, display showcases, etc., the rest of the cardboard box that is opened by removing the lid is used in the same way as the tray. Etc. are used.
When placing directly on the display shelf by stripping, it is difficult to maintain the alignment of the products by moving the other adjacent products by taking out the products, and rearranging is difficult and difficult.
The tray has a low peripheral side wall, and there is a risk that the product etc. slides out of the tray or the stacked product collapses. On the other hand, a tray with a high side wall has a problem that it is inconvenient to transport and store the tray.
The box that is opened by removing the lid portion is generally disposable, which not only wastes resources but also causes a problem of waste disposal.

  Similar to the box that is opened by removing the lid, there is a container made of a synthetic resin that can be expanded, assembled, folded, and disassembled. However, the molding of synthetic resin requires a molding die that requires a high production cost for each component part, and is actually not used for a small number of manufacturing. Therefore, it is desirable from the viewpoint of manufacturing cost that the box manufactured by a small number is formed by using cardboard or cardboard and cutting and sticking.

  As a container formed by cutting using cardboard or cardboard, a paper box having a bottom structure described below has been proposed. That is, as shown in FIG. 6, the side surfaces 101 and 102 (not shown) and the end faces 103 and 104 (not shown) constituting the box are alternately connected to each other and the bottom sides 117 to 120 is a paper box connected to each other, and the bottom surface constituting member of one side surface is a half bottom surface plate 117 having a width equal to or less than the half width of the bottom surface of the wife surface, and the other bottom surface constituting member is a full bottom surface plate 118 covering the entire bottom surface The bottom structural members 119 and 120 of 103 and 104 (not shown) have a substantially trapezoidal shape, and each bottom plate is partially bonded to the adjacent half bottom plate 117 or full bottom plate 118 to form a bottom lid. A bottom structure of a paper box in which a part of a bottom plate to be bonded to 118 is further extended to form bonded portions 119b and 125, and a slit 126 for reducing rigidity is provided on the extended base of the bonded portion has been proposed (for example, Patent Document 1). All bottom plate 118 has a fold 118a (not shown).

  Further, in order to maintain a state in which the extended portion of the side surface of the folding container is folded back to a predetermined position, a configuration is proposed in which a protrusion is provided at the tip of the extended portion and the protrusion is inserted into a groove provided at the lower end of the side surface. (For example, refer to Patent Document 2).

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

  In the paper box proposed by the above-mentioned Patent Document 1 and the like, referring to FIG. And the bottom surface of the bottom plate 118 and the bottom surface of the bottom plate 118 are low in durability. Therefore, this paper box is unsuitable for a container for storing a bottle filled with a liquid or a container for storing an object having a large specific gravity. That is, when a heavy object is stored in this box, the bottom plate portion may be distorted downward or the adhesion may be peeled off, resulting in a so-called bottom out.

  As described above, the paper box proposed by the above-mentioned Patent Document 1 is provided with a notch 126 for reducing rigidity at the extended base portion of the adhesive portion. However, when the folding container is expanded and assembled from the folded state, the entire bottom plate 118 exceeds the pulling force below the bonding portion 125, that is, the force to return to the folded state, that is, the full bottom plate 118 tries to lift. Power remains. As a result, it is necessary to put a heavy object in the folding container immediately after the expansion, or to push down the bottom plate 118 by hand. The tendency that the bottom plate is lifted is that when a light object is put in the folding container, the bottom portion is lifted and inclined, so that the contents arranged on the bottom plate fall down or scatter. . The same inconvenience occurs when the product is first put on the raised bottom plate.

The folding container 1 of the present embodiment is efficient for displaying products such as ice cream in a frozen showcase, that is, arranging and stacking the stored products, replenishing them when they are gone, and rearranging or replacing them. It is a folding container that can be used for a long time and can be used repeatedly over a long period of time, has an open top and no lid member.

The folding container 1 is formed by cutting a paper or resin sheet having a water-absorbing and non-staining surface. As shown in FIG. 1, the folding container 1 has a rectangular first long side surface portion A, a first short side surface portion B, and first long side surface portions A that are formed successively in succession. It has the 2 long side surface part C and the 2nd short side surface part D of the same shape and dimension as the 1st short side surface part B.
The first long side surface portion A, the first short side surface portion B, the second long side surface portion C, and the second short side surface portion D are formed by arranging a plurality of vertically long vent holes L.
A side margin M to be affixed to the second short side surface portion D is formed at the end of the first long side surface portion A opposite to the first short side surface portion B.

The first long side surface portion A has a lower long bottom surface portion F extending from the first lower side 1. The second long side surface portion C has a rectangular upper long bottom surface portion E extending from the second lower side 2 thereof.
The first short side surface portion B has a trapezoidal first short bottom surface portion G extending from the third lower side 3 thereof. The second short side surface portion D has a trapezoidal second short bottom surface portion H extending from the fourth lower side 4 thereof.

The first short bottom surface portion G extends from the first fold line 12 toward the lower long bottom surface portion F via the first fold line 12 inclined by 45 ° with respect to the third lower side 3 of the first short side surface portion B. And a first margin J.
The second short bottom surface portion H extends through the second fold line 14 inclined by 45 ° with respect to the fourth lower side 4 of the second short side surface portion D and extends from the second fold line 14 toward the upper long bottom surface portion E. And a second margin K.

  The upper long bottom surface portion E has a protrusion 5 at its tip. The protrusion 5 is inserted into the groove 10 provided in the second lower side 2 during the expansion.

The first margin J has a first notch 22 that is recessed from the end side 24 on the lower long bottom surface portion F side in the extending direction of the third lower side 3 and is formed along the first fold line 12.
The second margin K has a second cut 26 that is recessed from the end 20 on the upper long bottom surface E side in the extending direction of the fourth lower side 4 and is formed along the second fold line 14.

The upper long bottom surface portion E has a reinforced mountain fold line 16 extending in a direction away from the second short bottom surface portion H from the first intersection 30 of the second lower side 2 and the first boundary side 6 toward the tip. The first boundary side 6 is a boundary between the second long side surface portion C and the second short side surface portion D.
The lower long bottom surface portion F is cut on a straight line extending from the second intersection point 34 of the first lower side 1 and the second boundary side 7 in a direction away from the first short bottom surface portion G toward the tip. The second boundary side 7 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 surface portion E, the folded portion N on the second short bottom surface portion H side is folded back so that the reinforcing fold line 16 shown in FIG.

  Next, an adhesive paste is applied to the front or back surface of the side margin M. Adhesive glue is applied to the entire back surface of the first margin J and the second margin K in FIG.

  Next, as shown in FIG. 2 to FIG. 5, the surfaces to which the side margin M, the first margin J, and the second margin K are applied are respectively referred to as the second short side portion D, the upper long bottom portion E, and the half. Affixed to the surface in FIG.

(Folding / Extended)
When the folded container in the state shown in FIG. 2 and FIG. 3 assembled as described above is pushed from the left-right direction in the figure to reduce the left-right dimension, the first short bottom surface portion G is lowered via the first margin J. Pull down the long bottom face F. Further, the second short bottom surface portion H pulls down the upper long bottom surface portion E via the second margin K. As a result, as shown in FIGS. 4 and 5, a stretched state that can be used as a container is obtained.

Since the folded portion N is provided, in this expansion operation, no frictional resistance force is generated between the upper long bottom surface portion E and the second short side surface portion D, and the expansion is not hindered. Further, the lower long bottom surface portion F is cut on a straight line extending from the second intersection point 34 of the first lower side 1 and the second boundary side 7 in a direction away from the second short bottom surface portion G toward the tip. Further, no frictional resistance force is generated 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 surface portion E is pushed downward, and the protrusion 5 of the full length bottom surface portion E is inserted into the groove 10.

  As a result of this extension, the bottom of the folding container 1 is attached to the upper long bottom E and the half long in addition to the first margin J and the lower long bottom F and the second margin K and the upper long bottom E. The long bottom surface portion F sandwiches the folded portion N continuous with the upper long bottom surface portion E. Therefore, the bottom portion of the folding container has a large rigidity and a large durability, and the possibility of the bottom portion being pushed down and deformed even when a heavy object is accommodated is reduced.

  On the other hand, since the protrusion 5 of the upper long bottom surface portion E is inserted into the groove 10, the upper long bottom surface portion E is predetermined even if the load on the bottom portion is lightened or the load on the bottom portion becomes light or the load becomes zero. Maintain the horizontal plane state. This configuration not only enables efficient replacement of the contents, but also has the great advantage that the contents can always be kept in order on a stable horizontal surface.

When transporting or storing folding containers that do not contain anything, fold them. The folding is performed by placing a finger on the reinforced fold line 16 at the inner bottom and removing the protrusion 5 from the groove 10.
In this operation, the full length bottom surface portion E is lifted so as to swing around the first lower side 1. Then, it crushes in the up-down direction in FIG.2 and FIG.3.

  At the time of folding, the first margin J has a notch 22 that is recessed from the end side 24 on the lower long bottom surface portion F side in the extending direction of the third lower side 3 and is formed along the first fold line 12. The bottom corner portion where the lower long bottom surface portion F and the first short bottom surface portion G are present can be easily folded without the sheet being excessively folded.

  Further, since the second margin K has a notch 26 that is recessed from the end side 20 on the lower long bottom surface portion F side in the extending direction of the fourth lower side 4 and is formed along the second fold line 14, The bottom corner portion where the bottom surface portion F and the second short bottom surface portion H are present can be easily folded without the sheet being excessively folded.
