Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a paper box, and more specifically, to a paper box with a cover-type lid in which the lid and body are integrated. It is related to

0002

[Conventional technology]

Various types of paper boxes with lids have been known in the past, and Figure 6 shows a typical example of the conventional paper box. A typical configuration was shown.

0003

[Problem that the idea aims to solve]

However, in the conventional box shown in FIG. 6, a lid part 62 is placed over a body part 61. When the lid is closed, the rear edge 62a of the side plate of the lid part 62 is free, so the elasticity of the paper Therefore, this portion expands outward, resulting in insufficient shape retention after assembly. deer However, there are problems such as dust easily entering through the large gaps in this wide area. was there.

0004 This invention was devised in view of these conventional problems that need to be solved, and its purpose is to To provide a paper box that is easy to assemble and has sufficiently improved shape retention after assembly. It's there.

[0005]

[Means to solve the problem]

In order to achieve the above purpose, the paper box of the present invention has a front plate on three sides of the lid plate and a front plate on both left and right sides. A lid part having a plate, and a body part having a front plate and left and right side plates on three sides of the bottom plate, The rear ends of the lid plate and the bottom plate are connected together via a back plate, and are held at the tip of the front plate of the lid part. A folding plate is provided between both ends of the front plate and the left and right sides of the lid. Similarly, a holding plate is connected to the tip of the front plate of the body, and a holding plate is connected to both ends of the front plate. A folding plate is provided between the left and right side plates of the body, and the left and right side plates of the lid are further provided. And each of the rear ends of the left and right side plates of the body has a locking cut that can be locked to each other. The structure is such that a locking piece is provided.

[0006]

[Effect]

In this invention, at the same time as the operation of putting the lid over the body, the locking of the lid is performed. By engaging the pieces with the locking pieces on the body through the locking notches, both the left and right sides of the lid can be secured. The rear edge of the plate is fixed to the rear end portions of the left and right side plates of the body. Therefore, when the lid is covered, Even in this state, the side plate of the lid reliably overlaps the side plate of the body, and sufficient shape retention is maintained. Also, since there is no large gap between the side plate of the lid and the side plate of the body, it is also dust-proof. Excellent.

[0007]

【Example】

Embodiments of the present invention will be described in detail below with reference to the drawings.

[0008] FIG. 1 is a developed plan view showing one embodiment of the present invention. In FIG. 1, three of the cover plates 1 On the sides, there is a lid front plate 3 via the fold line 2, and left and right side plates 6, 7 of the cover via the fold lines 4 and 5. are connected to each other, and on the three sides of the bottom plate 8, a body front plate 10, a fold line The left and right side plates 13 and 14 of the body are connected through the plates 11 and 12, respectively, and the lid plate 1 and the bottom plate 8 are connected to each other at their rear ends via a back plate 15. Tip of lid front plate 3 A lid retaining plate 17 is connected to the lid retaining plate 17 via a fold line 16, and the lid retaining plate 17 has a A figure-of-eight fold line 18 that becomes narrower is provided. In addition, both sides of the front plate 3 of the lid part and the left and right The lid is folded to the left and right between the lid side plates 6 and 7 via the fold lines 19 and 20 or 21 and 22. The folding plates 23 and 24 are provided respectively, and the folding plates 23 and 24 of the lid part have respective corner corners. 45-degree diagonal fold lines 25 and 27 were established starting from the section, and a portion was extended outward. It has locking parts 26 and 28. On the other hand, the tip of the body front plate 10 is also connected via the fold line 29. A body holding plate 30 is provided in series, and a figure-of-eight fold line 31 is provided on the body holding plate 30. . Similarly, there are fold lines 32 between both ends of the body front plate 10 and the left and right body side plates 13 and 14. , 33 or 34, 35, body folding plates 36, 37 are provided on the left and right, respectively. The folding plates 36, 37 are provided with 45-degree diagonal folding lines 38, 40 and have locking parts 39, 41. ing.

[0009] Furthermore, locking notches 46 and 47 are provided at the rear ends of the left and right side plates 6 and 7 of the lid, respectively. Lid part locking pieces 44, 45 having A body locking piece 50 having locking notches 52 and 53 at the rear ends of the right side plates 13 and 14, respectively; 51 are connected via fold lines 48 and 49, and the lid locking piece and the body locking piece are The structure is such that the notches are locked by engagement with each other. In addition, the lid locking pieces 44, 45 The body locking pieces 50 and 51 are separated from both ends of the back plate 15.

0010 Next, to explain the assembly method, first, from the unfolded state shown in Figure 1, the left and right lid folding plates are assembled. 23, 24, lid side plates 6, 7, body side plates 13, 14, and body folding plates 36, 37 inward. Repeat. Next, fold the lid retaining plate 17 inward and align the figure-eight fold line of the lid retaining plate 17. Fix only the central part surrounded by 18 (the part indicated by code 54 in the figure) to the front plate of the lid ( (see Figure 2). Fold the body holding plate 30 inward in the same way, and Attach the part to the body front plate 10. From this flat folded state, each folded side When the plates 6, 7, 13, 14 and each front plate 3, 10 are folded up again, the lid part will fold. The parts of the folding plates 23, 24 and body folding plates 36, 37 that are close to the connection side with each side plate hold the lid. Stand up by raising each side of the plate 17 and the body holding plate 30, and finally The left and right sides of each holding plate 17, 30 fold the lid and body folding plates 23, 24, 36, 37 into two. Hold it in place by folding it in. In addition, the lid part locking pieces 44, 45 and the body part locking piece 50 , 51 are bent inward through the fold lines between each side plate.

[0011] In this way, the box can be opened from the flat folded state with one touch as shown in Figure 3. can be assembled. When putting the lid on, use the lid locking pieces 44, 45 and the body clasp. Place the lid portion 56 over the body portion 57 so that the locking pieces 50 and 51 are engaged with each other with their locking notches. so that Figure 4 is a perspective view from the back side with the lid covered, and Figure 5 (a) 4 is a cross-sectional view of the main part taken along the line A-A in FIG. 4, and (b) is a cross-sectional view of the main part taken along the line B-B in FIG. ing. As is clear from Figures 4 and 5, when the lid is put on, the side plate of the lid It is kept securely overlapping the side plate of the body, and there is no space between the side plate of the lid and the side plate of the body. No large gaps will be created. Moreover, at the same time as the operation of putting the lid on, the lid and body Since the locking pieces of the parts can be engaged with each other, there will be no operational inconvenience. stomach.

0012

[Effect of the idea]

As explained in detail above, the paper box of the present invention is easy to assemble and At the same time as the operation of putting the lid over the body, the locking piece of the lid and the locking piece of the body are disconnected. By engaging through the inset, the rear edge of the left and right side plates of the lid can be attached to both the left and right sides of the body. Since it is fixed to the rear end of the side plate, even when the lid is covered, the side plate of the lid is attached to the side of the body. It can be kept reliably overlapped on the board and maintain sufficient shape retention. Also, Excellent dust resistance as there is no large gap between the side plate of the lid and the side plate of the body. .
