Description

TECHNICAL FIELD The present invention relates to a packaging paper box useful for packaging cakes.

2. Description of the Related Art Conventionally, as a wrapping paper box for a cake box, a tunnel-type outer box having a roof with an arcuate cross section and a boat-shaped inner box with a lid that is inserted into and removed from the outer box are used in combination. Different formats have been proposed.

The problem that the invention is going to solve is that the above-mentioned conventional type wrapping paper box requires folding,
The arcuate roof of the outer box is separate from the main body, and the main body, the arcuate ridge, and the inner box with lid are made up of three parts, which has the drawback of complicated structure and complicated assembly work. there were. A one-part construction of this kind of wrapping paper box has also been proposed (for example, Japanese Utility Model Publication No. 52-42835).
(See Japanese Patent Publication), this is a deployment and assembly type that assembles a box from the fully deployed state, so lacks the speed of assembly, and is not suitable for applications such as cake packaging that is quickly assembled and used in stores. Met.

The present invention has been made for the purpose of eliminating such conventional problems.

Means for Solving the Problems The present invention comprises a tunnel type main body and opening / closing lids provided at front and rear entrances of the main body, the main body being a bottom wall and a bottom wall of the bottom wall. It consists of both side walls rising from both left and right ends through folds and an arcuate roof part that covers between the upper ends of both sides, while the opening and closing lid is on both side walls of the main body part and front and rear ends of the bottom wall part. A large number of parallel ruled lines are formed in the arc-shaped roof portion of the main body portion in parallel with each other at a small interval in the lengthwise direction, and are formed of a continuous lid member, and between the bottom wall portion and the side wall portion. Based on one fold, at the position where the distance between the side passing through the bottom wall and the side passing through the side wall is equal,
The present invention relates to a packaging paper box characterized in that one ruled line selected from the above-mentioned many ruled lines is present as a fold for folding the main body.

In the packaging paper box according to the present invention, a large number of parallel ruled lines are formed at a small interval on the roof of the main body.
The formation part of this ruled line is weaker in strength than other parts, and the arc-shaped roof part is extended flat at the part of the ruled line,
Alternatively, the original arcuate state can be automatically restored from the flatly extended state. Thus, although the main body part has the arcuate roof part integrally, it can be folded with the arcuate roof part flatly extended. Folding is performed on the selected ruled line. Further, in the present invention, since the main body part is integrally provided with the opening / closing lids at the entrances at both ends, it is not necessary to use the combination with the inner box with the lid as seen in the conventional product. Thus, according to the present invention, the structure is simple with a one-part structure and can be folded, so that the assembly is easier than that of the deployable type.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows the product of the present invention in an assembled state, and FIG. 2 shows a developed view of the product. The main body part (1) is a seam allowance (15), a bottom wall part, which are successively coupled through ruled lines. (11), one side wall part (12), an arcuate roof part (13) and the other side wall part (14), which is composed of an arcuate roof part (13) and, if necessary, both side wall parts (12), On the upper part of (14), there are many ruled lines (2) in parallel with a small space,
It is formed in the length direction. Eaves (131) are formed at both ends of the roof (13) in the longitudinal direction.

The means for forming the ruled line (2) is not particularly limited, but when it is formed by arc-shaped punching as shown in FIG.
This is preferable because it has a good spring property.

At both ends of both side wall parts (12) and (14) of the body part (1),
Inner and outer lid plates (31) and (32) of the same shape and size as the inlets (16) and (16) (see FIG. 1) at both ends of (1) are also provided at both ends of the bottom wall (11). Auxiliary lid pieces (33) that are folded up between the plates (31) and (32) are connected to each other, and these constitute the opening / closing lid (3) of the entrance (16). At the tip of the inner lid plate (31) of the opening / closing lid (3), a finger hook (31
1) is formed, and a cut (312) is formed in the proximal end coupling portion, and when closed, the insertion (321) of the tip of the outer lid plate (32) is inserted into this cut (312). It has become. In the other figures, (41) and (41) are semicircle-shaped handles punched from the roof (13), and (42) is a transparent film that closes the punch holes.

FIG. 4 shows a folded state of the product of the present invention. In this folded state, the arcuate roof portion (13) is extended substantially flat at the part of the ruled lines (2). Further, the ruled line (21) selected from the ruled lines (2) ... and actually functioning as a folding line is, as shown in FIG. 1, a bottom wall part (11) and a side wall part (1).
From the ruled line (a) between 2), it occupies a position where the left-handed and right-handed distances are equal.

From the state shown in FIG. 4, by folding up the side wall portions (12) and (14), the main body portion (1) can be assembled as shown in FIG. ) Automatically restores to a substantially arcuate state due to the spring property of the ruled lines (2) ....

From the state shown in FIG. 1, as shown in FIG. 5, the inner lid plate (31)
, Then fold up the auxiliary lid piece (33) as shown in FIG. 6, and then close the outer lid plate (32) and at the same time insert the insert (321) at the tip of the outer lid plate (32) into the inner lid. By inserting the cut (312) in the plate (31), the inlet (16) of the main body (1) can be closed by the opening / closing lid (3) as shown in FIG.

In this closed state, as shown in FIGS.
Since the arcuate portion of the outer lid plates (31) (32) supports the arcuate roof portion (13) on the lower surface of the eaves portion (131), the roof portion (1
The circular arc shape of 3) can be stably and reliably held. Such an opening / closing lid (3) can be easily opened by performing the reverse procedure.

As described above, according to the present invention, in the tunnel type packaging box having the roof portion having the arcuate cross section, this can be configured as a one-part structure, and the structure can be simplified and the cost can be provided at the same time.
Since it can be folded using the ruled line formed on the arcuate roof part, it can be assembled from the folded state when packaging the product, which is much easier to assemble than the deployable type, and in the assembled state both side walls Since the assembled state of the kamaboko type or the tunnel type can be maintained by erecting, the operation of storing the article in the main body (1) and the lid of the opening / closing lid can be performed regardless of the structure that can be folded and assembled. The closing operation can be performed very easily, and it is particularly suitable for applications such as cakes in which quick and quick assembly is desired at the time of over-the-counter sales.
