Description

  The present invention relates to a packaging container.

  Conventional hexahedron packaging containers tend to fall even when the packaging container is upright on the ground, etc., making the packaging container itself self-supporting, and standing upright on the ground It was difficult to make it in a state of letting it go.

  For this reason, as a technical document filed earlier than the present invention, in a packaging container made of hexahedrons, the lower end of the back surface of the packaging container is made shorter than the front surface of the packaging container, and the foot girder portion is formed at the lower end of the back surface There is a document that discloses a packaging container that is provided and has the packaging container upright at the front lower end and the back girder portion of the packaging container (see, for example, Patent Document 1).

Japanese Utility Model Publication No. 63-8570

  However, since the packaging container of the above-mentioned patent document 1 has a single leg girder part, the strength of the leg girder part cannot be maintained unless the thickness of the part constituting the leg girder part is increased. Moreover, since the leg girder part is composed of a single piece, the back side of the leg girder part is exposed to the outside, and the back side of the leg girder part is visible from the outside.

  The present invention has been made in view of the above circumstances, and forms a packaging container and its container capable of improving the design of the leg part while ensuring the strength of the leg part for standing the packaging container upright. It aims at providing the blank sheet for doing.

(First embodiment)
<Configuration example of packaging container 100>
First, a configuration example of the packaging container 100 of the present embodiment will be described with reference to FIGS. 1 is a front view of the packaging container 100 of the present embodiment, FIG. 2 is a side view, and FIG. 3 is a rear view. FIG. 4 is an enlarged view of the leg portion 20, and FIG. 5 is an enlarged view of the suspended portion 22.

  As shown in FIGS. 1 to 3, the packaging container 100 in the present embodiment includes a front surface portion 6, a bottom surface portion 2, a top surface portion 3, a right side surface portion 4, a left side surface portion 5, and a back surface portion 1. Have and configure. The front surface part 6 constitutes the front surface of the packaging container 100. The bottom surface portion 2 constitutes the bottom surface of the packaging container 100. The upper surface portion 3 constitutes the upper surface of the packaging container 100. The right side surface part 4 constitutes the right side surface of the packaging container 100. The left side surface portion 5 constitutes the left side surface of the packaging container 100. The back surface portion 1 constitutes the back surface of the packaging container 100.

  As shown in FIG. 1, the front surface portion 6 of the packaging container 100 of the present embodiment has an extraction window A so that the inside of the packaging container 100 can be visually recognized from the extraction window A. As a result, the contents (not shown) stored inside the packaging container 100 can be viewed from the extraction window A. The shape of the extraction window A is not particularly limited, and it is possible to configure the extraction window A of any shape depending on the intended use. Further, the number of the glazing windows A is not particularly limited, and any number of glazing windows A can be formed according to the use application. Further, although the packaging container 100 of the present embodiment is configured to provide the extraction window A, it may be configured to not provide the extraction window A.

  Further, as shown in FIGS. 2 and 3, the packaging container 100 of the present embodiment has a leg portion 20 at the lower end 1 a of the back surface portion 1 and is packaged by the lower end 6 a and the leg portion 20 of the front surface portion 6. The container 100 is configured to be able to stand upright on the ground plane.

  As shown in FIG. 4, the leg portion 20 of the present embodiment includes a first leg plate 20-1 provided at the lower end 1 a of the back surface portion 1 and a second bottom surface plate 12-constituting the inside of the bottom surface portion 2. Two leg plates 20-1 and 20-2 connected to one end of 2 and two leg plates 20-1 and 20-2 are overlapped to constitute a leg portion 20 having strength.

  For this reason, since it becomes possible to comprise the leg part 20 which is stronger than the case where the leg part 20 is constituted by a single leg plate, as shown in FIG. 2, the lower end 6a of the front part 6 and the leg part Even when the packaging container 100 is set upright on the ground plane at 20, a large amount of load can be applied to the legs 20.

  In addition, the leg portion 20 is configured by overlapping the back surfaces of the two leg plates 20-1 and 20-2, and the outside of the leg portion 20 is configured by the surfaces of the two leg plates 20-1 and 20-2. become. For this reason, the back surfaces of the leg plates 20-1 and 20-2 are not exposed to the outside, and the leg portion 20 having excellent design can be configured.

  In addition, as shown in FIG. 2, the packaging container 100 of this embodiment can adjust the inclination | tilt angle of the packaging container 100 by adjusting the length of the leg part 20.

The second suspension plate 22-2 provided in the second upper surface plate 13-2 that constitutes the outer side of the third suspension plate 2-2 is superposed to constitute a strong suspension 22.

  For this reason, it becomes possible to constitute the suspension part 22 having a higher strength than when the suspension part 22 is constituted by a single suspension plate. In addition, since the suspension portion 22 and the upper surface portion 3 are configured to be connected by two plates, the strength of the connection portion where the suspension portion 22 and the upper surface portion 3 are connected is increased, and many loads are connected. It can be applied to.

  Further, as shown in FIG. 5, the suspended portion 22 of the present embodiment includes a first suspended plate 22-1 constituting the suspended portion 22 and a first upper surface plate 13-constituting the inside of the upper surface portion 3. 1 and the second suspension plate 22-2 is connected to the second upper surface plate 13-2 that constitutes the outside of the upper surface portion 3, and is thus applied to the first suspension plate 22-1. The load can be distributed to the first upper surface plate 13-1, and the load applied to the second suspension plate 22-2 can be distributed to the second upper surface plate 13-2.

  The packaging container 100 in the present embodiment can be formed of a paper material such as cardboard or cardboard. Further, the packaging container 1 can be formed of a plurality of sheets or one sheet of paper material.
