The above packaging container is made by folding one blank. Therefore, no consideration is given to a packaging container made by combining an upper wall portion and a lower wall portion, each of which is separately prepared.

The present specification provides a technique for arranging an opening for taking out the contents on a side wall in a packaging container provided with an upper wall portion and a lower wall portion.

The techniques disclosed herein relate to packaging containers. The packaging container may be manufactured by combining the upper wall portion and the lower wall portion. The lower wall portion includes a bottom wall and a lower side wall arranged upward from the bottom wall, and the upper wall portion includes a top wall arranged apart from the bottom wall. The bottom wall and the top wall are provided with an upper side wall which is arranged downward from the top wall and is arranged so as to overlap the lower side wall, and the lower side wall and the upper side wall provide the bottom wall and the top wall. A space is enclosed, one of the lower side wall and the upper side wall located on the outside is provided with a front surface and side surfaces located on both side ends of the front surface, and the one side wall is provided. The lower side wall and the upper side wall, which are defined by the first break line and have a first break portion extending from the front surface to the side surface, the other side wall located inside is the first break portion. It may be open inside the front surface of the.

In the above configuration, in the packaging container in which the lower side wall and the upper side wall are arranged so as to overlap each other, a first break portion for forming an opening for taking out the contents is arranged on the outer side wall, and the inside is arranged. The side wall arranged in is open inside the fractured portion. Therefore, by breaking the first broken portion, the contents contained in the packaging container can be taken out from the outside of the packaging container. According to this configuration, it is possible to form an opening that reaches the contents from the outside of the packaging container only by breaking the first broken portion.

Each of the lower side wall and the upper side wall has the side surface and the back surface, and the lower side wall surface is arranged so as to overlap the inside of the upper side wall surface on the side surface and the back surface. The upper end of the lower side wall is located at substantially the same position as the upper end of the upper side wall on the side surface and the back surface, and the lower end of the upper side wall is near the lower end of the packaging container on the side surface and the back surface. It may be located in. When the first break is broken to form an opening in the side wall of the packaging container, the packaging container becomes vulnerable to a force from above. In the above configuration, since the upper side wall and the lower side wall that overlap each other are provided, the force from above can be supported by the upper side wall and the lower side wall. As a result, even if the first break portion is broken and an opening is formed in the side wall of the packaging container, it is possible to suppress the decrease in strength against a force from above. As a result, when a plurality of packaging containers are stacked and arranged after the first fractured portion is broken, it is possible to prevent the packaging containers arranged below from being crushed.

The first break line may be inclined upward toward the front surface on the side surface. According to this configuration, the first breaking line can be easily broken from the side surface to the front surface.

The first break portion may extend from the front surface to the top wall, and the first break line may extend from the front surface to the top wall. The broken portion can be broken to form a large opening in the packaging container. As a result, the contents in the packaging container can be easily visually recognized and taken out.

The other side wall may have an opening inside the side surface of the first break that opens after the first break is broken. According to this configuration, the fingers can be hooked on the side wall by inserting the fingers into the opening. As a result, the first broken portion is broken, and the packaging container after the opening is formed in the side wall of the packaging container can be lifted by hooking a finger on the side wall.

The other side wall comprises a second break portion defined by a second break line inside the side surface of the first break portion, and the second break portion is joined to the inside of the first break portion. When the first breaking portion is broken along the first breaking line, the second breaking portion is broken along with the first breaking portion along the second breaking line, and the opening is opened. The portion may be opened after the first fractured portion is fractured by the second fractured portion being fractured along the second fracture line. According to this configuration, the second fractured portion, which is the joint portion between the upper side wall and the lower side wall, can be separated from the inner side wall together with the first fractured portion. Thereby, when the broken portion is broken to form an opening in the packaging container, the upper side wall and the lower side wall can be separated.

(Breaking method of broken portion 100)
Next, a method of breaking the broken portion 100 of the packaging container 10 will be described with reference to FIGS. 7 to 10. As shown in FIG. 7, the user first pushes the bent pieces 82c and 84c into the packaging container 10. As a result, the bent pieces 82c and 84c rotate about the rear end side. At this time, since the openings 32b and 34b of the side plates 32 and 34 are arranged inside the bent pieces 82c and 84c, the bent pieces 82c and 84c can be smoothly rotated inward.

As a result, the user can insert a finger through the opening formed by rotating the bent pieces 82c and 84c, and hook the finger from the inside of the packaging container 10 to the rear end portion of the broken portion 100. can. Then, as shown in FIG. 8, the user pulls the break portion 100 in the direction of the arrow in FIG. 8 to break the break lines 82b and 82d and the break line 82a. The break lines 82a and 82d are inclined with respect to the front-rear direction, and the break lines 82b are curved. Therefore, the breaking lines 82a, 82b, and 82d can be broken smoothly as compared with the case where they extend in parallel in the front-rear direction. Similarly, the user breaks the break lines 84b and 84d and the break lines 84a. As a result, as shown in FIG. 9, when viewed from the front, both ends of the fractured portion 100 are separated from the upper side wall 72.

When the break lines 82b and 82d and the break lines 82a are broken, the break portions 32c and 34c of the lower side wall 22 are broken from the side plates 32 and 34 along with the break portions 100. As a result, openings 32e and 34e are formed in the side plates 32 and 34.

Next, the broken portion 100 can be separated by breaking the break line 80a of the front plate 80.

As shown in FIG. 10, the packaging container 10 after the break portion 100 is cut off has a large opening formed on the front side. As a result, the contents can be easily taken out from the front opening while the contents are housed. Therefore, for example, when displaying the product as the content in the store, the product is stored by separating the broken portion 100 without having to take it out of the packaging container 10 and display the product on the shelf. The packaging container 10 may be placed in the store. This makes it possible to simplify the display work.

Further, in the packaging container 10, the top wall 70 remains after the broken portion 100 is cut off. Therefore, a plurality of packaging containers 10 can be arranged so as to be stacked in the vertical direction (see FIG. 10). The upper ends of the side plates 32 and 34 of the lower side wall 22 are located at substantially the same positions as the upper ends of the side plates 82 and 84 of the upper side wall 72. Approximately the same includes cases where they are the same and cases where they are slightly different. Further, the upper end of the back plate 36 of the lower side wall 22 is located at substantially the same position as the upper end of the back plate 86 of the upper side wall 72. Further, the side plates 82 and 84 of the upper side wall 72 and the back plate 86 substantially coincide with the lower end of the packaging container 10. Approximate coincidence includes the case of being positioned and the case of being slightly deviated.

According to this configuration, the packaging container 10 arranged at the bottom supports the packaging container 10 stacked at the top by the side plates 32, 34, 82, 84 and the back plates 36, 86 which are doubly arranged. can do. As a result, it is possible to prevent the packaging container 10 arranged below from being deformed.

Further, by inclining the break lines 82d and 84d of the side plates 82 and 84 forward, it is possible to prevent the lower end sides of the side plates 82 and 84 from being shortened after the break portion 100 is cut off. As a result, it is possible to prevent the strength of the packaging container 10 from being lowered after the broken portion 100 is cut off. Further, by leaving the lower end sides of the side plates 82 and 84 long, it is possible to prevent the upper wall portion 12 from falling forward.

Further, by breaking the broken portion 100, the broken portions 32c and 34c are broken and the openings 32e and 34e are formed. According to this configuration, as shown in FIG. 10, the fingers can be hooked on the lower side wall 22 by inserting the fingers into the openings 32e and 34e. As a result, the fingers can be hooked on the opened packaging container 10 and lifted.

The upper side wall 72 and the lower side wall 22 are joined by adhering the outer surface of the broken portions 32c and 34c and the inner surface of the broken portion 100. According to this configuration, the joint between the upper side wall 72 and the lower side wall 22 can be released by separating the broken portion 100. Thereby, after using the packaging container 10, the packaging container 10 can be easily put away.
