Description

Paper-plastic products and molds for making the paper-plastic products 【0001】

This creation is about a paper-plastic structure, especially a paper-plastic product and a mold for making the paper-plastic product.

【0002】

With environmental pollution, climate upheaval, energy shortages and other factors, modern people mostly choose to buy goods with the advantages of environmental protection, pollution-free and reuse. Among them, the paper pulp made of recycled cardboard and newsprint is molded by molding, so its environmental protection, pollution-free and reuse characteristics make paper-plastic one of the currently popular packaging materials.

[0003]

After the pulp molding is made into the initial product, the extension of the initial product will be reserved for the cutting operation, so that the preliminary product is cut into the paper-shaped box of the set size. In addition, at present, the cutting process such as die cutting or rocking cutting, the cutter is cut in the direction of the vertical extending section, so the edge of the extending edge of the periphery of the paper-plastic box can only be presented by a right angle.

[0004]

However, the peripheral edge of the above-mentioned paper-plastic box has the following disadvantages. Since the commodity packaging box requires a plurality of paper-plastic boxes to be stacked on each other, the peripheral edges of the paper-plastic boxes will be in contact with each other, but the periphery of the paper-plastic box is at right angles and the periphery is beveled. In contrast, the right angle of the circumference causes the area and frictional force to be in contact with each other to be small, resulting in a low stability of the combination of the packages.

[0005]

In view of this, the creator has made great efforts to solve the above problems by focusing on the above-mentioned prior art, and has devoted himself to the research and development of the above-mentioned problems.

[0006]

The purpose of this creation is to provide a paper-plastic product and a mold for making the paper-plastic product, which is a combination of a hot-pressing mold and a cutting operation, so that the outer periphery of the paper-plastic product has inclined edges, and the inclined edge can increase contact. The friction force makes the combination of the paper-plastic finished product and the package upper cover stack more stable when the outer periphery of the paper-plastic product and the upper cover of the package are in contact with each other.

【0007】

In order to achieve the above object, the present invention provides a paper-plastic product comprising: a paper-plastic product having a main body portion and an extension plate disposed around the main body portion, the outer peripheral edge of the extension plate having a slanted edge and The bottom has a bottom surface, and the angle between the inclined side and the bottom surface is an acute angle.

[0008]

In order to achieve the above object, the present invention provides a mold for manufacturing a paper-like product as described above, comprising: a first mold having a first surface having a first surface and a ring disposed at the first surface a meandering plane portion around a cavity; and a second mold interfacing with the first mold, the second mold having a second surface having a second cavity and being disposed in the second a ridge of the outer side of the cavity, the rib having an inclined wall adjacent to a side of the second cavity, the inclined wall and the second surface having an obtuse angle, the second cavity and the first die The hole corresponds to the pressing, the rib is correspondingly pressed with the plane segment, and the first mold and the second mold are pressed on both sides of the paper product to form the inclined wall.

【0009】

This creation also has the following effects:

[0010]

First, through the combination of hot pressing die and cutting operation, the paper has the purpose of having inclined edges on the outer periphery of the finished product, and solves the problem that the outer periphery of the conventional paper-plastic box can only be presented at right angles.

[0011]

Second, the outer periphery of the paper-plastic finished product has a slanted edge, and the slanted edge can increase the contact area and the frictional force compared with the conventional vertical edge, so that when the inclined edge of the paper-plastic product and the package upper cover are in contact with each other, the paper-plastic product and the package upper cover The stacking stability is higher.

[0012]

Thirdly, because the inclined side is pressed by the inclined wall, the inclined side area is pressed and the density is high, so that the structural strength of the inclined side area is higher, and it can be firmly combined with the upper cover of the package.

[0034]

In the fifth step, as shown in step e of FIG. 1 and FIG. 7 to FIG. 8 , the bottom edge 305 is aligned to perform a cutting operation, so that the paper forming initial 30 is cut into a paper product 40, and the inclined side 304 is made. Formed on the outer periphery of the paper product 40. Wherein, the cutting operation is to provide a cutter, and the cutter is cut to the bottom edge 305 by punching or rocking.

[0035]

In addition, since the number of the ridges 212 and the grooves 303 is two, the two grooves 303 are disposed on both sides of the main body portion 301 such that the inclined sides 304 are formed on opposite sides of the outer periphery of the paper product 40.

[0036]

As shown in FIG. 2 to FIG. 5, the combination of the present hot press mold 10 has a first surface 11 by using the first mold 1, the first surface 11 has a first cavity 111 and the ring is disposed at the first cavity 111. The surrounding flat section 112; the second mold 2 and the first mold 1 are mutually opposed, the second mold 2 has a second surface 21, and the second surface 21 has a second cavity 211 and a convex disposed outside the second cavity 211 The strip 212 has a slanted wall 213 adjacent to the side of the second cavity 211. The slanted wall 213 and the second surface 21 have an obtuse angle θ1, and the second cavity 211 is pressed against the first cavity 111.
