[0020]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a sandwich packaging paper box according to the present invention will be described based on an embodiment shown in the drawings. The sandwich wrapping paper box (A) of this embodiment is assembled in a desired form after required parts are joined from the unfolded state shown in FIG.
[0021]
FIG. 3 is an exploded plan view showing the sandwich wrapping paper box (A) with its inner surface as a front surface, and folds (21) and (22) on a pair of long sides of a square bottom wall (1). A first side wall (2) and a second side wall (3) each having a right-angled isosceles triangular shape are connected to each other via the through hole.
[0022]
A flap (4) is continuously provided on one short side of the bottom wall (1) via a fold (23), and the first joint piece (5) is provided on the other short side via a fold (24). ) Are connected.
[0023]
On both side walls (2) and (3), folding folds (25) and (26) are provided from the center of each hypotenuse to a right-angle corner. On one side of the second side wall (3), a second joining piece (6) is provided side by side with the first joining piece (5) via a fold (27), and the second joining piece (6) is provided on the upper side. An upward arcuate cut (7) is provided over the folding fold (26).
[0024]
A rectangular lid piece (8) is connected to the first side wall (2) via a fold (28) on the oblique side, while the bottom side is provided via a fold (29) on the other side. A back wall (12) of the same shape and size as the wall (1) is continuously provided.
[0025]
The lid piece (8) is provided with a window hole (10) occupying at least half the area of the lid piece at the center, and the window hole (10) is covered with a transparent synthetic resin film (11) from the inside. ing. Since the window (10) is greatly widened in the width direction of the lid (8), the short side end of the synthetic resin film (11) covering the window (10) is closed. ) Is adhered to the inner surface of the first side wall (2) and the inner surface of the insertion piece (9) described later.
[0026]
Further, an insertion piece (9) that is inserted into the arc-shaped cut (7) of the second side wall (3) through a fold (30) is continuously provided on the long side on the free end side of the lid piece (8). At the same time, the insert piece (9) is provided with a similar fold line (31) on the extension of the fold line (25) of the first side wall (2).
[0027]
The sandwich packaging paper box (A) is placed in a folded state as shown in FIG. 5 until it is used, but the manufacturing process from the expanded state to the folded state is shown. Will be described. First, as shown in FIG. 4, from the unfolded state, the second side wall (3) is folded inward from the two-fold fold (26), and the second joint piece (6) is overlaid on the inner surface of the bottom wall (1). At the same time, the first joining piece (5) is similarly bent inward and overlapped on the inner surface of the bottom wall (1). Thereafter, the first side wall (2), the lid piece (8) and the insertion piece (9) are folded inward from the folds (25) and (31) together with the back wall (12) to form the back wall (12). Is adhered to the first joint piece (5) and the second joint piece (6). FIG. 5 is a plan view of the packaging paper box for sandwiches (A) in which the whole has been folded into two after the attachment.
[0028]
Finally, when the flat folded state is released and the side walls (2) and (3) are raised from the bottom wall (1) or the back wall (12), an expected form as shown in FIG. (A) is obtained. Actually, it is somewhat difficult to accommodate the sandwich because the elastic repulsive force of the paper attempts to restore the flat folded state. However, after one sandwich (S) is firstly accommodated while lightly sandwiching the side walls (2) and (3) with one hand, the box is placed so that the sandwich (S) can lean on one of the side walls. When it is tilted, the elastic repulsive force of the paper is also weakened, and when the second and third sandwiches (S) are stored, it is not necessary to pinch the side walls (2) and (3) with strong and strong force, and the storing operation is also easy. Easier to do.
[0029]
After storing a predetermined number of sandwiches (S), (S)..., The lid is closed and the insertion piece (9) is inserted into the notch (7), whereby the packaging state in which the lid is closed as shown in FIG. can get.
[0030]
The size of the window (10) of the sandwich packaging paper box (A) of the above embodiment is set to occupy slightly more than half of the area of the lid piece (8). If the size is too small, the sandwich (S) accommodated is difficult to see if the lid is closed, and if the size is too large, the strength of the cover piece is reduced. Preferably.
[0031]
The window hole (10) is covered with a transparent synthetic resin film (11) slightly larger than its outer shape. For example, the window hole (10) is transparent over the entire inner surface of the sandwich packaging paper box for waterproofing or cosmetics. When a synthetic resin film is laminated, it may be covered with the transparent synthetic resin film.
[0032]
