<Opening the lid>
Next, opening and closing of the lid will be explained.
The inside of the carton 1 shown in FIG. 1 is filled with articles such as sweets in advance. As shown in FIG. 2, the lid 70 is opened by lifting the lid 70 upward. The consumer performs an operation to lift the lid 70 upward by, for example, gripping the gripping piece 14 of the lid 70.

When the lid portion 70 is lifted upward, the upper top panel 10 is broken along a pair of fourth breaking lines 17 provided on the top top panel 10. Thereby, the upper top panel 10 is separated into the lid portion 70 and the pair of tip pieces 18. As described above, the tip piece 18 is adhesively fixed to the lower top panel 50. Therefore, the tip piece 18 cannot follow the upward operation of the lid part 70 and remains on the lower top panel 50.

Further, when the lid part 70 is lifted upward, the pair of first break lines 56 provided on the upper top panel 10 break, and the pair of first cut parts 58 surrounded by the first break lines 56 are removed from the bottom top panel. It is removed from 50. The first cutout portion 58 is adhesively fixed to the lid portion 70. Therefore, the first cutting section 58 follows the upward operation of the lid section 70, moves upward together with the lid section 70, and separates from the lower top panel 50.

A pair of first openings 75 are formed in the lower top panel 50 by separating the pair of first cut portions 58 from the lower top panel 50 . The first opening 75 is a portion of the lower top panel 50 from which the first cutout 58 has been removed. Further, the second cutout portion 59 remains between the pair of first openings 75.

Moreover, when the lid part 70 is lifted upward, the third break line 15 provided on the lid part 70 is broken, and the third cutout part 13 surrounded by the third break line 15 is cut out from the cover part 70. The third cutout 13 is adhesively fixed to the second cutout 59. The third cutout part 13 cannot follow the upward operation of the lid part 70 and remains on the second cutout part 59 of the lower top panel 50. As a result, a third opening 77 is formed in the lid portion 70. The third opening 77 is a portion of the lid 70 from which the third cutout 13 is removed.

As shown in FIG. 2, the second cutout 59 is disposed between the pair of first openings 75 when the lid 70 is open. As shown in FIG. 3, the second cutout portion 59 can be removed from the lower top panel 50 side by breaking the lower top panel 50 along the first breaking line 56. The second cutout portion 59 is cut out, for example, by inserting a finger into either or both of the pair of first openings 75, grasping the second cutout portion 59, and lifting it upward. By removing the second cutout portion 59 from the lower top panel 50, a second opening 76 is formed in the lower top panel 50. The second opening 76 is formed to connect the pair of first openings 75. The second opening 76 is a portion of the lower top panel 50 from which the pair of first cutout portions 58 and the second cutout portion 59 disposed therebetween have been removed.

In this embodiment, the opening area of the first opening 75 is sufficiently small with respect to the articles filled inside the carton 1. On the other hand, the opening area of the second opening 76 is sufficiently large for the articles filled inside the carton 1. After opening the lid part 70, the consumer can take out the article from the carton 1 by further removing the second cutout part 59.

According to the present embodiment, the lower top panel 50 includes a first break line 56 formed in a continuous loop shape and a first cutout portion surrounded by the first break line 56 and bonded to the lid portion 70. 58, a second break line 57 connected to the first break line 56, and a second cutout portion 59 surrounded by at least a portion of the first break line 56 and the second break line 57.

According to the present embodiment, by opening the lid part 70, the first cutout part 58 is removed from the lower top panel 50 to form the first opening part 75, and a second cutout part is formed at a position continuous with the first opening part 75. 59 can remain. Further, by cutting the second cutout portion 59 along the second break line 57, a second opening 76, which is an enlarged first opening 75, can be formed. Therefore, the consumer needs to touch the second cutout part 59 when taking out the article from the carton 1, and can draw the consumer's attention to the second cutout part 59. According to this embodiment, by providing the printing P1 such as a pattern on the second cutout portion 59, it is possible to provide the carton 1 with a high design quality. Further, the second cutout portion 59 can be used as an entertainment card, thereby adding further value to the product. In addition, if a cautionary note or the like is printed on the second cutout portion 59 when consuming the articles in the carton 1, it is possible to reliably alert the consumer.

Further, according to the present embodiment, even if the lid part 70 is opened, the second cutout part 59 remains on the lower top panel 50 side and partially blocks the second opening part 76. Therefore, the lid part Even if the entire carton 1 shakes significantly when the carton 70 is opened, articles inside the carton 1 can be prevented from scattering from the second opening 76.

In this embodiment, the second cutout portion 59 is printed with printing P1. The print P1 includes at least one of text information, graphics, designs, or photographs. The consumer removes the second cutout 59 to provide a second opening 76 for removing articles from the carton 1. Therefore, the printing P1 on the second cutout portion 59 is easily visible to consumers. By applying the printing P1 such as text information, figures, designs, or photographs to the second cutout portion 59, the information related to the printing P1 can be reliably provided to the consumer. In addition, in FIGS. 1 to 3 and FIG. 5, the printing P1 and P2 are expressed by a dot pattern.

In this embodiment, the lower top panel 50 is provided with a plurality of first cutouts 58, and the second cutout 59 is arranged between at least two of the plurality of first cutouts 58. As described above, the first cutout portion 58 separates from the lower top panel 50 when the lid portion 70 is opened to form the first opening portion 75. Therefore, the second cutout 59 is arranged between at least two first openings 75. According to this embodiment, the consumer can insert his or her fingers into the two first openings 75 to remove the second cutout portion 59, thereby simplifying the procedure for cutting out the second cutout portion 59.

In this embodiment, the breaking strength of the second breaking line 57 is preferably greater than the breaking strength of the first breaking line 56. Here, "breaking strength at the breaking line" means the force required to break the panel at the breaking line. According to this embodiment, when lifting the lid part 70, the first break line 56 can be broken preferentially over the second break line 57. Thereby, when lifting the lid 70, the first cutout 58 can follow the lid 70, and the second cutout 59 can be separated from the first cutout 58 and remain on the lower top panel 50 side. can.

In this embodiment, it is preferable that the total length of the connecting portions 57q of the second breaking line 57 is longer than the total length of the connecting portions 56q of the first breaking line 56. When such a configuration is adopted, the breaking strength of the second breaking line 57 can be made larger than the breaking strength of the first breaking line 56. Note that the "total length of the connecting parts of the breaking line" is the sum of the length dimensions of all the connecting parts along the breaking direction in the entire length of the breaking line.

Further, in the present embodiment, it is preferable that the ratio of the connecting portion 57q to the notch 57p of the second breaking line 57 is larger than the ratio of the connecting portion 56q to the notch 56p of the first breaking line 56. When such a configuration is adopted, the breaking strength of the second breaking line 57 can be made larger than the breaking strength of the first breaking line 56. In addition, "the ratio of the connecting part to the notch part of the breaking line" means the ratio of the length dimension along the breaking direction of the notch part and the connecting part that are adjacent to each other in the breaking direction. The length dimensions of the first break line 56 and the second break line 57 along the break direction of the cut portions 56p, 57p and the connecting portions 56q, 57q are not necessarily constant. Therefore, the "ratio of the connecting part to the cut part of the breaking line" is not necessarily constant. In this embodiment, it is sufficient that the above-mentioned ratios of all the second break lines 57 are larger than the above-mentioned ratios of the first break lines 56. In other words, the minimum value of the ratio of the connecting portion 57q to the notch 57p of the second breaking line 57 should be greater than the maximum value of the ratio of the connecting portion 56q to the notch 56p of the first breaking line 56.

Note that in the first breaking line 56 of this embodiment, the second portion 56b may be a complete cut without the connecting portion 56q. However, by providing the connecting portion 56q in the second portion 56b, lifting of the lower top panel 50 of the first cutout portion 58 can be suppressed during the process of applying adhesive to the adhesive area, etc., and the process of applying the adhesive becomes smooth. You can proceed to That is, according to this embodiment, the box manufacturing process can be simplified by providing the connecting portion 56q in the second portion 56b.

According to the present embodiment, the lid portion 70 includes the third break line 15 formed in a continuous loop shape, and the third cutout portion surrounded by the third breakage line 15 and bonded to the second cutout portion 59. 13 are provided. According to this embodiment, by lifting the lid part 70 upward, the third cutout part 13 remains on the lower top panel 50 and is removed from the lid part 70. Thereby, the third opening 77 can be provided in the lid 70, and when the lid 70 is closed after removing the second cutout 59, the inside of the carton 1 can be exposed from the third opening 77. . Furthermore, according to the present embodiment, the third cutout 13 is attached to the second cutout 59. Therefore, a three-dimensional design can be applied to the surface of the second cutout portion 59.

Note that the opening area of the third opening 77 in this embodiment is sufficiently small with respect to the articles filled inside the carton 1. Therefore, it is possible to prevent the articles in the carton 1 from falling out of the carton 1 through the third opening 77 with the lid 70 closed.

Note that it is preferable that the printing P2 provided on the surface of the third cutout portion 13 is continuous with the print P1 provided on the surface of the second cutout portion 59 (for example, a pattern). In this case, the printing P2 of the third cutout part 13 can be emphasized and expressed with respect to the print P1 of the second cutout part 59. In addition, it is more preferable that the printing P2 on the third cutout portion 13 is continuous with the printing on the outer surface of the lid portion 70. In this case, it is possible to realize a design in which the shape of the periphery of the print P2 on the third cutout portion 13 changes as the lid portion 70 is opened and closed.

In this embodiment, the breaking strength of the second breaking line 57 is preferably greater than the breaking strength of the third breaking line 15. According to this embodiment, when lifting the lid part 70, the third break line 15 can be broken preferentially over the second break line 57. Thereby, when lifting the lid part 70, the third cutout part 13 can be cut out from the lid part 70, and the third cutout part 13 can be left on the lower top panel 50 side together with the second cutout part 59. In order to make the breaking strength of the second breaking line 57 larger than the breaking strength of the third breaking line 15, the total length of the connecting portions 57q of the second breaking line 57 is set to the connecting portion 15q of the third breaking line 15. can be longer than the sum of the lengths. Further, the ratio of the connecting portion 57q to the notch 57p of the second breaking line 57 may be larger than the ratio of the connecting portion 15q to the notch 15p of the third breaking line 15.
