[Technical field to which the invention belongs]

 The present invention relates to a paper-shaped rectangular container integrally formed with a bottom plate and a side plate, which facilitates storage and transportation of hot foods such as freshly baked cakes and gratin, and prepared foods.

[0002]

[Prior art]

 Conventionally, as this kind of paper square dish container, for example, there is a container described in Japanese Utility Model Laid-Open No. 4-135412.

[0003] In this conventional technique, a paper plate container in which a side plate is formed upright around a bottom plate by bending a single sheet of paper, is connected to the outer edge of the square bottom plate to form a square annular side plate. Are formed integrally on the paper-like material, radial fold lines connecting the inner corners and the outer corners of the side plate are provided, and V-shaped fold lines extending perpendicularly to the outer edge of the side plate from the inner corners are provided on both sides of each of the fold lines. They are formed to form a deployment structure of a dish-shaped container, and the radial absorption lines and the V-shaped folding lines are bent outward and inward, respectively. This is a paper square dish container with a side plate standing upright on the outer edge of the bottom plate.

[0004]

[Problems to be solved by the invention]

 According to the above-mentioned conventional technique, since many decorative pieces project greatly outside the corners of the planar contour of the square dish container, these many decorative pieces hinder the handling of the container. Stacking is not possible, and the entire side wall of the container is a single piece, so it is vulnerable to external forces. Moreover, since there is no horizontal gripping piece, it is difficult to carry containers containing foods. In particular, there is an essential problem that containers containing hot contents are not portable.

[0005] Separately from this conventional example, one sheet of paper blank is bent as in JP-A-6-156469 to form a substantially rectangular bottom portion, and a long side and a short side folded up from the bottom. Each pair of side walls is formed, and the extension on both sides of the long side is folded back and glued to the outer surface of the adjacent short side wall to form the tray body, and a water-absorbing sheet is applied to cover the inner surface of the bottom. Although a paper tray with a sticker is also well-known, in this conventional example as well, the entire container side plate is a single piece, the waist is weak, and there is no horizontal gripping piece in the container. There is an inherent problem that there is a danger of burns and it is not portable.

According to the present invention, a reinforcing piece is folded back and adhered to an opposing side plate to reinforce it, and a gripping piece is integrally protruded outside each of the reinforcing pieces, so that hot food such as a freshly baked cake confectionery can be obtained. An object of the present invention is to make it easy to carry a container storing items to another place.

[0007]

[Means for Solving the Problems]

 The purpose of the above-mentioned invention is to make a paper container with a side plate standing upright around the bottom plate by bending and bonding one sheet of paper, and connecting it to the outer edge fold line of the square bottom plate respectively. By forming side plates, these side plates are erected from the folding line, and the side plates adjacent to each other among the side plates in the erected state are adhered to each other with an adhesive margin, thereby erecting each side plate, In addition, a reinforcing piece extending to the upper side of at least two of the side plates facing each other is folded outward and bonded to the outer surface of the side plate, and a gripping piece connected to the reinforcing piece is laterally extended and projected. It was achieved by doing.

[0008]

[Embodiment of the invention]

 Embodiments will be described with reference to the drawings. First, the basic structure of the present invention is to form a paper container in which a side plate is integrally formed upright around the bottom plate as shown in Fig. 1 by bending a single sheet of rigid paper such as kneaded silicone resin. For example, a plate-shaped plate having an unfolded structure as shown in FIG. 2 in which a rectangular side plate 3 connected to an outer edge fold line 2 of a rectangular bottom plate 1 and an adhesive margin 4 projecting and projecting from these side plates 3 are integrally formed. Prepare the material.

Then, these side plates 3 are erected from the fold line 2 through the state of FIG. 3 as shown in FIG. 1, and the mutually adjacent side plates 3 of the upright side plates 3 are bonded to each other. By adhering at the margin 4, each side plate 3 is kept upright as shown in FIG. 1, and the reinforcing piece 5 extending to the upper side of at least two opposing side plates 3 of each side plate 3 is removed. The paper container according to the present invention is folded back to the side and adhered to the outer surface of the side plate, and the holding piece 6 connected to the reinforcing piece 5 is laterally extended and projected as shown in FIG.

Therefore, the opposing side plate 3 can be reinforced by the two-piece structure with the reinforcing piece 4, and even if a hot thing is put in the container according to the present invention surrounded by the bottom plate 1 and the side plate 3, Since the heat insulating property is larger than that of metal or the like, the gripping piece 6 does not become hot, and the two gripping pieces 6 are held with both hands, so that the container can be carried safely and easily.

【Example】

 The planar shape of the bottom plate 1 in the present invention is not limited to a rectangular shape as shown in each figure, but may be a square, a hexagon, an octagon, or the like. By increasing the number of divisions in this manner, a container having a more circular shape can be obtained. The bonding margin 4 protruding outside the side plate 3 can also be reduced.

The container of the present invention can also be a fairly deep (or shallow) paper square container, as shown in FIG. 4 or FIG.

Further, as the paper sheet for forming the paper-made rectangular container according to the present invention, a composite paper, that is, a laminated paper obtained by applying or laminating a heat-adhesive synthetic resin thin film having no problem on food hygiene on one or both sides thereof is used. Thus, the above-mentioned bonding margin 4 is adhered to the outer surface of the side panel 3 by heating and pressing the bonding margin 4 which has been bent outward from the side panel 3 in contact with the outer surface of the side panel 3 using a known heating mold (not shown). Orientation, heat sealing of the reinforcing piece 5, and the like can be facilitated, and it is not necessary to use an adhesive.

Furthermore, even when a liquid is put into the container according to the present invention, the corner of the container is folded up and adhered and fixed outside the container, so that the paste does not dissolve or leak water. Therefore, foods and beverages could be cooked in the container according to the present invention.
