[Industrial applications]

 The present invention relates to a paper tableware formed by cutting a board having an appropriate thickness into a predetermined shape, providing a predetermined folding line on the surface of the cut piece, and performing bending and heat sealing.

[0002]

[Prior art]

 Generally, polystyrene foam tableware or paper tableware is often used as disposable tableware. Among them, polystyrene foam tableware is made integrally by foam molding using a foam material, and some recesses are provided according to the demand of packaging. They have the advantage that they are strong, convenient for serving food, and easy to manufacture. However, it does not decompose or melt naturally after disposal, which causes environmental and ecological damage.

Further, the above-mentioned conventional paper tableware has an advantage that it is environmentally and ecologically friendly. In many cases, the bottom is formed by cutting a paperboard into a predetermined shape, providing fold lines on the surface, and bonding the folded portions together. However, cutting and bending techniques are limited, the thickness is not sufficient, and the constituent parts are often composed of a single layer. For this reason, if the strength is insufficient and the load is large, it may tear or break during use. In addition, the polystyrene foam tableware and conventional paper tableware often had a smooth bottom surface and were slippery.

【Example】

 In the present invention, first, a paperboard made of pulp and additives, or a paperboard which is made by smearing polyethylene on paper and laminating it to an appropriate thickness is used to form a bottom of a predetermined shape such as a triangle, a square, a rectangle, or a polygon. Cut into a shape centered on (10). The cut piece is, that is, a stretched piece (18) that is regularly stretched outward is provided around the bottom (10), and a fold line (a) (b) parallel to the surface of the stretched piece (18). (C), (d) and (e) are provided. In the present invention, these folding lines (a) to (e) are folded and heat-sealed so that the periphery of the bottom (11) is projected upward to form a two-layer wall and the anti-slip piece (15). ) Is a paper tableware having a shape provided on the bottom surface, which is a paper tableware having a heat insulating effect, a reinforcing effect, and a non-slip effect.

FIG. 1 is a developed view of the present invention in an unmolded state. When the paper tableware (10) of the present invention is made rectangular, a folding line (a) is pressured on the surface of the cutting office and a bottom (11) is provided at the center. An inner wall component (12) is provided so as to surround the periphery of the bottom (11). A folding piece (16) composed of a symmetrical triangle sandwiched by three folding lines (e) is provided at a corner portion adjacent to each inner wall constituting piece (12) around the bottom (11). By folding this fold line (e) outward or inward and heat-sealing, the inner wall component piece (12) is diagonally erected around the bottom (11) (shown in FIG. 2).

Further, an extension piece (18) extending outward from the folding line (b) is provided around each inner wall constituent piece (12). On the surface of the stretched piece (18), fold lines (c) and (d) are provided from the inside to the outside, and the edge component piece (13), the outer wall component piece (14), and the anti-slip piece (15) are arranged in order from the inside. Set up.

Protrusions (131) are provided at both ends of each edge component (13), and both sides of the outer wall component (14) are reduced as they extend outward from the adjacent protrusions (131). As shown in FIG. Moreover, the inner wall constituting piece (12) and the outer wall constituting piece (14) are provided so that the heights of the inner wall and the outer wall after molding are substantially equal to each other. Finally, the anti-slip piece (15) is provided adjacent to the outer wall component piece (14) by the fold line (d) parallel to the fold line (c).

The piece (13), the outer wall constituting piece (14), and the non-slip piece (15) are substantially U-shaped. Further, a non-slip piece (15) is attached to the bottom surface of the corresponding bottom (11) (shown in FIG. 4) and heat-sealed to reverse the space between the inner wall constituent piece (12) and the outer wall constituent piece (14). Form a triangular gap (17). This creates a heat insulating effect on the wall and also reinforces the wall and the bottom, forming the non-slip paper tableware of the present invention.

Separately, protrusions (131) are provided at both ends of each edge component piece (13), and the protrusions (131) corresponding to each other at the time of molding are vertically overlapped and heat-sealed, so that the corners of the tableware The position is reinforced.

Further, according to the present invention, the bottom can have various shapes such as an equilateral triangle, a quadrangle, and a polygon according to actual demand. This mainly increases or decreases the number of fold lines (a), increases or decreases the corresponding inner wall component pieces (12), folding and folding pieces (16), etc., and increases the number of fold lines (a) to the stretched pieces (18) adjacent to the inner wall component pieces (12). The edge component pieces (13), the outer wall component pieces (14), and the folded and folded pieces (16) provided by the folding lines (b), (c), and (d) are also relatively increased or decreased.

Further, according to the present invention, the widths of the inner wall component pieces (12) and the outer wall component pieces (14) are changed according to demands to form walls having different heights, and the walls are formed into a bowl shape or a box shape after molding. You can
