Description

  The present invention relates to a paper plate that is preferable for displaying, selling, and the like by placing an article such as a piece of Western confectionery.

In recent years, paper plates have been used as plate members to display and sell a piece of food such as Western confectionery because of environmental and recycling requirements.
The paper plate is provided by bending upstanding pieces so as to surround the periphery. The standing piece is provided with a fold line inside the base piece, bent from the fold line part, and the part outside the fold line is raised, but when the standing piece stands, the circumference of the outline of the base piece In contrast, the peripheral length of the upright piece of the finished paper plate is shortened. As a result, the corner portion of the upright piece has to be absorbed by the shortened peripheral length, resulting in wrinkles in the corner portion and appearance. It gets very bad.
Therefore, conventionally, when making an upright piece surrounding the periphery of the paper plate, the corner portion of the base piece constituting the upright piece is separated from the folding line corner portion, and after the upright piece is raised, 2. Description of the Related Art A paper dish is known in which a provided margin piece is glued so that wrinkles are not generated at a corner (see, for example, Patent Document 1).
Japanese Utility Model Publication No. 05-0707018

  The paper plate of Patent Document 1 has a triangular shape in plan view and accommodates pizza or the like cut out for one person. After assembling to surround the bottom of the base piece, the corner portion of the remaining piece constituting the standing piece is cut off. In this structure, an adhesive margin is provided at the separating portion, the upright piece is bent from the folding line, and the adhesive margin is glued.

The paper plate of the above-mentioned patent document 1 is formed of a base piece (blank material) by cutting a paper material into a predetermined shape, a step of bending the base piece from a fold line, and a corner of an upright surrounding standing piece. The process requires a process of gluing the glue margin provided in the section after bending, which increases the number of steps for producing the paper plate, makes the production complicated and troublesome, and inevitably increases the cost.
The present invention has been made to solve the problems in the conventional paper plates.

  The present invention is a paper blank used to display and sell Western confectionery, etc., and is a paper blank made by punching a paper blank into a predetermined shape. It is possible to provide a paper plate that can be formed without generating wrinkles in a corner portion, does not require an adhesive margin, is easy to manufacture, and is extremely advantageous in terms of cost.

The corner portion of the convex portion is arranged at the peripheral portion, and the corner portion of the convex portion can exert a rib effect to increase the strength and rigidity of the paper plate.

  In the invention according to claim 5, in claim 3, since the convex portion is composed of a plurality of independent convex portions, the area of the portion on which the confectionery etc. on the bottom of the paper plate is placed becomes the area of the upper surface of the convex portion, Adhesion of Western confectionery or the like on the bottom of the paper dish is reduced, and it becomes easier to remove the confectionery or the like from the paper dish.

The best mode for carrying out the present invention will be described below with reference to the accompanying drawings. The drawings are viewed in the direction of the reference numerals.
1 is a perspective view of a paper plate according to the present invention, FIG. 2 is a developed view of the paper plate, showing a base piece that is a blank material, and FIG. 3 is a plan view of the paper plate after molding. FIG. A description will be given with reference to these drawings.
In the illustrated embodiment, the paper plate 1 is a square (square) paper plate, and includes a flat bottom portion 2 and an upright piece 3 that surrounds the peripheral edge of the bottom portion 2.

The upright piece 3 of the paper plate 1 includes four corner portions 4 (... indicates a plurality. The same applies hereinafter) and a peripheral piece portion 5 (intermediate portion) between the corner portions 4.
The peripheral piece portions 5 are inclined to stand outward and upward at a predetermined angle, for example, about 60 °, and similarly the corner portions 4 are outwardly and upwardly shallower than the peripheral piece portion 5, for example, 30 °. Standing up to a certain degree.
As described above, a paper plate having the upright pieces 3 with the corners 4... Having a shallow angle around the bottom 2 and the peripheral pieces 5.

  FIG. 2 shows a blank material made of a paper sheet constituting the base piece 10 forming the paper plate. The base piece 10 has a quadrangular (square) shape with arcuate corners 11... A fold line (virtual) 13 similar to the outline is set in advance on the inner side of 12, and a bottom portion is formed later on the inner side 14 of the fold line 13.

As described above, the base piece 10 is folded at the fold line 13 by press molding, bent from the fold line, and the surplus portion 15 outside the fold line 13 is bent so as to incline outward and upward at the above-mentioned angle. Let
Thus, the paper plate according to the present invention is formed as shown in FIG.
The obtained paper plate 1 has a bottom 2 which is square as shown in the figure, and the upright pieces 3 are inclined upward and outward from the peripheral edges 6 of the four rounds of the bottom 2 formed by folding lines at the angle described above. Each of the corner pieces 5 is set to be deep (60 ° in the embodiment) and the corner portions 4 are set shallow (30 ° in the embodiment) as described above. The edge portions 4a of the portions 4 ... project outward in a plan view from the edge portions 5a of the peripheral piece portions 5 that connect these portions.

By the way, the base piece 10 shown in FIG. 2 is bent up from the fold line 13 into a valley fold and is raised to form the upright piece 3 that surrounds the bottom, but with respect to the circumference of the outline 12 of the base piece 10, A difference occurs between the peripheral length of the upright pieces 3 constituting the outline of the plate, that is, the peripheral length of the outer shape 12 of the base piece is large, and the peripheral length of the upright pieces 3 of the paper plate after molding is shortened. For this reason, the difference in circumference must be absorbed somewhere.
Since the standing piece, particularly the corner portion 4 cannot absorb the difference in circumference, an extra portion of this portion is generated, and wrinkles are derived from the corner portion.

  In the present invention, the difference in the circumferential length is set so that the upright piece 3 is inclined upward and outward as described above, and the bending angle of the peripheral piece portions 5 is as described above. Since the corner portion 4 is set to be deep (60 ° in the embodiment) and the corner portion 4 is shallow (30 ° in the embodiment), the edge portion 4a of each corner portion 4 is an edge of the peripheral piece portion 5 that connects the corner portions 4 ... It protrudes outward in plan view rather than the portion 5a, and the outward protrusion of the corner portion absorbs the difference in circumferential length, thereby suppressing the occurrence of wrinkles in the corner portions 4 ... It is possible to form the upright pieces 3 including the corner portions 4.

This relationship will be described in detail with reference to FIG. 4. FIG. 4 is a plan view of the paper plate, and is an enlarged explanatory view showing 1/4 of the paper plate.
The figure shows a quarter portion including the corner portion of the paper plate. From the length P11 to P12 of the edge portion 5a of the peripheral piece portion 5 of the paper plate 1 and the similar P1 of the outline of the base piece 10 The lengths of P2 are equal.
Therefore, since there is no difference between the circumferences, it is not necessary to absorb the circumference.

With respect to the distance from the outline P2 of the base piece 10 to P3 of the arcuate corner portion 11, the length from the similar portions P12 to P13 of the upright piece of the paper plate 1 is the length of the corner portion 4 protruding outward. Since it is continuous in front, it is curved and is longer than P2 to P3. At this portion, the peripheral length (length) of P1 to P3 of the base piece 10, the peripheral piece portion 5 of the paper plate 1, and the corner portion 4 The peripheral lengths (lengths) between P11 to P13 of the edge portions 5a and 4a substantially coincide with each other, and the curved portion of the corner portion, the formation of the following arc portion, and the outward protrusion of this portion cause mutual mutual The difference in the perimeter of the outline is absorbed.
Therefore, the difference between the circumferential lengths of the base piece 10 and the paper plate 1 is absorbed by the front and rear edge portions 5b and 5b of the corner portion 5 that gently curves and protrudes outward, and wrinkles and the like are generated at the corner portion. It is suppressed.

5 is a plan view of a second embodiment of the present invention, and FIG. 6 is a sectional view taken along line 6-6 of FIG.
In the present embodiment, a convex portion 7 having a large area is provided at the central portion of the bottom portion 2 of the paper plate 1 so as to protrude upward. The convex portion 7 is a step of forming the paper plate 1 in the bottom portion 2. To be integrally molded. The upper surface 7a of the convex portion 7 is parallel to the upper surface of the bottom portion 3 and is flat.
The convex part 7 is a rhombus in plan view in the embodiment, and the corner parts 8 at the four corners are arranged at positions corresponding to the center part in the length direction of the peripheral piece parts 5 of the four circumferences in the bottom part 2.

On the convex part 7, for example, the bottom of a confectionery is placed, and the confectionery is turned and sold. When the confectionery or the like is peeled off from the bottom 2 of the paper plate 1, the bottom of the confectionery or the like is raised one step by the convex portion 7, so that it can be easily removed from the paper plate and taken out easily.
In the embodiment of FIG. 5, the corner portions 8 do not face the corner portions 4, but face the intermediate portions of the peripheral piece portions 5. Strength and rigidity are increased, and the base piece can be made thin in consideration of shape retention after molding.

7 is a plan view showing a modified embodiment of FIG. 5, and FIG. 8 is a cross-sectional view taken along line 8-8 of FIG.
In the present embodiment, a plurality of convex portions 17 are provided so as to protrude on the bottom portion 2 of the paper plate 1 independently of each other.
In the embodiment, the convex portions 17 are circular convex portions in the central portion, and four convex portions are provided radially around the central portion, and the surface tip of the upper surface of each convex portion 17 is small. The upper surface was set flat so as to be parallel to the upper surface of the bottom 2.

  In the above, the bottom of the confectionery and the like is placed and supported on the upper surface of the convex portion 17 of a small area, and is displayed and sold in this state, but when the confectionery is peeled from the bottom 2 of the paper plate, Is placed and supported on the bottom 2b of the paper plate 1 in a small area, so that there is little adhesion to the projections 17 and the confectionery can be easily taken out of the paper plate.

The embodiment of the present invention has been described above.
In the embodiment, the paper plate is a quadrangle (square). However, as described above, it is only necessary to absorb the difference in peripheral length between the corner piece and the base piece by projecting outward from the peripheral piece part. Therefore, a paper plate having a corner portion and a peripheral piece portion surrounded by standing pieces can be implemented.
Accordingly, it can be easily understood that the present invention can be easily applied to a paper plate of a polygon, for example, a triangle, a pentagon, a hexagon, and the like.
