Description

  The present invention relates to a packaging box that stores and sells confectionery and the like.

  As this type of packaging box, there has heretofore been known that an opening zipper is provided in the vicinity of the upper end of the box, and the zipper is torn off at the time of opening. However, there are problems that the zipper that is torn down becomes garbage, and the recloseability (resealability) of the box once opened is not good.

  On the other hand, Patent Document 1 includes a bag type that includes an opposing front wall and a rear wall, and an open / close flap that is connected to the upper edge of the rear wall extends so as to partially cover the front wall from the upper end side. A packaging box is disclosed. In such a bag-type packaging box, there is no zipper that is thrown away as garbage and the recloseability is good, but the following problems remain.

In this box, when the consumer picks up the “picking piece (opening / closing flap)”, the “opening piece” adhered to the back side of the “picking piece” is broken together with the “picking piece”. The contents take-out opening appears. The consumer picks only the “pick piece”, and the “opening piece” adhered to the “pick piece” is incidentally broken along with the picking operation.
In such a configuration, when the adhesive strength between the “pick piece” and the “opening piece” is not sufficient, even if the consumer picks up the “pick piece”, the “opening piece” does not follow this. It can happen that it is not opened (no opening appears).

Japanese Patent Laid-Open No. 9-48427

  In view of the above-described conventional circumstances, an object of the present invention is to provide a configuration in which an opening is reliably formed with an opening operation in the bag-type packaging box.

The packaging box of the present invention includes a front wall and a rear wall that are opposed to each other, and an open / close flap that is continuously provided at the upper edge of the rear wall extends so as to partially cover the front wall from the upper end side.
The front wall includes a tearable opening piece defined by a breaking line in a region near its upper end, and the opening / closing flap is bonded to the opening piece on the inner surface thereof.
The lower end of the breaking line that divides the opening piece extends to a position below the lower end of the opening / closing flap that covers the front wall, and is surrounded by the "lower end of the breaking line" and the "lower end of the opening / closing flap". The piercing area is exposed on the front wall so as to be visible from the outside.
In this packaging box, the tearing area is pushed through with a finger, and the unsealing piece and the opening / closing flap are picked and opened together.

In the packaging box of the present invention having the above-described configuration, the “breaking region” that the consumer pushes when opening is surrounded by the “lower end of the breaking line” and the “lower end of the opening / closing flap”. It is exposed on the front wall so that it can be seen from the outside.
Therefore, even if a special opening operation explanation is not displayed on the box, the consumer simply says, “I just need to push my thumb there to open” just by looking at the front wall of the packaging box. Naturally realize (so-called ahodance characteristics).
Moreover, since the thumb pushed into the “breaking area” always holds the “opening piece” and “opening / closing flap” together with the index finger, the opening for taking out the contents is opened when the opening operation is performed. Will definitely be formed.

  In addition, the breaking line that divides the opening piece defines the opening area after the opening operation, but in the present invention, the breaking line extends to a position below the lower end of the opening and closing flap, As a result, the opening area is inevitably increased, and the contents can be easily taken out.

  A packaging box 10 according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1A is a perspective view showing a packaging box 10 before assembly, and FIG. 1B is a perspective view after assembly.

≪Overall structure of packaging box 10≫
The packaging box 10 can typically be assembled from one blank. In the illustrated example, finally, the opening / closing flap 30 is bonded to the opening piece 20 (or also to the front wall 11 in the vicinity thereof) on the inner surface thereof, and includes the front wall 11 and the rear wall 12 facing each other. A hexahedral box is formed (FIG. 1b).

An open / close flap 30 is connected to the upper edge of the rear wall 12 via a crease “A”. The opening / closing flap 30 is composed of a top surface portion 31 constituting the top surface of the box and a front portion 32 extending along the front wall 11, and both 31 and 32 are connected via a crease “B”. It is installed.
In a state where the packaging box is assembled (FIG. 1b), the opening / closing flap 30 extends so as to partially cover the front wall 11 from the upper end side.

  The front wall 11 has an opening piece 20 in a region near the upper end thereof. The unsealed piece 20 is partitioned by a breaking line 23 and can be torn from the front wall 11 as will be described in detail later. In the illustrated example, the unsealing piece 20 includes a tearing portion 21 located on the front surface of the box body and an upper flap 22 located inside the top surface portion 31 of the opening / closing flap 30 after assembly. 22 are connected via a crease “C”.

≪Push-break area 25≫
In FIG. 1 (b), the tearing region 25 can be visually recognized at a position slightly above the center of the front wall 11 of the packaging box 10. The tearing area 25 is an area where the consumer pushes the packaging box 10 with his / her finger when opening the packaging box 10.
In FIG. 1B, “the lower end portion 23a of the breaking line that divides the opening piece 20” extends to a position below the “lower end portion 30a of the opening / closing flap that partially covers the front wall 11”. . As a result, a breaking region 25 surrounded by the “lower end portion 23a of the breaking line” and the “lower end portion 30a of the opening / closing flap” is formed, and this is exposed on the front wall 11 so as to be visible from the outside.
FIG. 2 is a perspective view showing an example of the opening operation. The consumer pushes the tearing area 25 with the thumb (FIG. 2a), and with the thumb and index finger, grasps the opening piece 20 and the opening / closing flap 30 together and tears it upward to open the packaging box 10. Can be opened (Figure 2b).

With the above configuration, when the consumer performs the opening operation, not only the opening / closing flap 30 but also the opening piece 20 positioned below the same is picked together, and both of them are opened together, so that an opening is reliably provided. be able to.
That is, in the conventional example shown in Patent Document 1, since only the opening / closing flap 30 is picked and torn open, the unsealed piece 20 is moved forward when the bonding strength is insufficient or the bonding position is inappropriate. Although there are inconveniences such as remaining on the wall 11 (no opening is formed) or an appropriate opening is not formed, such an inconvenience cannot occur in the present invention.

  Further, as well shown in FIG. 1B, the breaking region 25 is formed on the front wall 11 in a state surrounded by the “lower end portion 23a of the breaking line” and the “lower end portion 30a of the opening / closing flap”. Because it is exposed, even if a special opening operation explanation is not displayed on the box, the consumer can just press the thumb and open it just by looking at the front wall 11 Self-awareness (so-called ahodance characteristics).

  Furthermore, since the “lower end portion 23a of the breaking line” extends downward beyond the “lower end portion 30a of the opening / closing flap”, the opening area after opening is inevitably increased. That is, the breaking line 23 that divides the opening piece 20 defines the opening area after the opening operation, but the breaking line 23 extends to a position below the lower end portion 30a of the opening / closing flap. As a result, the opening area increases and the contents can be easily taken out.

≪The shape of the tearing area that does not give pain to the thumb≫
The specific contour shape of the breaking region 25 is not limited to the illustrated example. However, in the example shown in the figure, a shape that is gentle to the thumb of the consumer is used when it is pushed through.
That is, in a state where the opening / closing flap 30 covers the front wall 11, the lower end portion 30a of the flap has a curved concave shape that is recessed upward (FIG. 1b). By adopting a curved shape along the belly of the thumb, no pain or the like is given to the thumb that performs the push-breaking operation.

≪Configuration for protecting contents≫
On the unsealed piece 20, a crease 24 is formed at a position in the vicinity of the tip of the torn portion 21 (on the lower end side in FIG. 1a). As shown in FIG. 1B, the crease 24 extends in the lateral direction near the bottom of the curved concave lower end 30 a of the open / close flap 30.
At the time of tearing open, the opening piece 20 is bent at a substantially right angle at the crease 24 and protrudes from the inner surface of the front wall 11 toward the inside of the box (FIG. 3b). In FIG. 3, the bent tip is represented by “T”, and the height thereof is also “T”. This height “T” is equal to the distance from the crease 24 to the lower end 23a of the unsealed piece.

  In the present invention, the tip portion “T” projecting at a right angle is limited to a size that does not press the contents 50 against the rear wall 12. For example, in the example shown in FIG. 3 (b), the contents 50 indicate a bag containing a long and narrow stick-shaped confectionery. If the tip “T” is too high, this may cause the stick confection to be pressed against the rear wall 12 and break the stick confectionery.

  In the present invention, this is prevented by limiting the dimension of the height “T”. The specific value of the height “T” is individually set according to the size of the box, the type and amount of the contents, and the like.
