Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bonded paper product for assembling a pattern and bonding a margin portion thereof to form a bag or a container, and a base paper for the pattern.

[0002]

2. Description of the Related Art Adhesive paper products are assembled into a bag or a container by assembling a paper pattern and gluing a margin portion thereof, for example, a bag such as an envelope or a paper bag, a fresh food / vegetable paper container, or a food baking cup. And container-shaped ones such as bread and baking pans. A glue margin is provided on the paper pattern of such an adhesively assembled paper product, and an adhesive is applied to the glue margin, and the glue margin portion is adhered to a corresponding partner to form the bag or the container. In such an adhesive-assembled paper product, for example, when forming the above-mentioned cup-shaped container, conventionally, a strip-shaped cylindrical paper and a circular bottom paper serving as a peripheral wall are separately cut out from a template base paper, and the cylindrical paper is formed. Adhesive is applied to the glue margin provided at the edge of one end of the paper, and the glue margin is adhered to the corresponding other end of the paper cylinder to form a tubular shape. In some cases, a substitute piece was provided, an adhesive was applied, and the tubular body and the bottom paper were adhered to each other to form a cup. Also, for example, an adhesive is applied to the entire surface of a single circular sheet of paper, and the center is used as the bottom, and the outer periphery of the bottom is bent so as to be raised with respect to the bottom to form the peripheral wall of the cup. In some cases, a plurality of portions that are partially folded and protruded at that time are bonded to each other to form a cup shape.

[0003]

In the case of using the above-mentioned bottom paper and cylinder paper and applying the adhesive manually, a great deal of labor and time were required. In addition, the application of the adhesive can be mechanized, but it is difficult to always apply a uniform amount, and there is a problem that the incidence of defective products is high.

In the case of forming a sheet by folding it from the above-mentioned one sheet of paper, since it is difficult to specify an adhesive portion, an adhesive is applied to the entire surface, and the adhesive is wasted. At the same time, since the portion to which the adhesive is applied is exposed in the state of being formed as a container, there is a problem that it is not preferable as a food paper container.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems and to easily prevent the application failure of the adhesive of the adhesively assembled paper product and to easily realize the automation of the application, the present invention provides:
A colored adhesive ink obtained by mixing a dye with a printable adhesive was printed on a glue allowance of a paper product assembled into a bag or a container from a pattern. In particular, the colored adhesive ink preferably contains an adhesive that can be adhered by heating. In addition, the glue allowance of the paper product assembled into a bag or a container from the pattern, and the mark when cutting the pattern base paper for cutting the pattern from the band-shaped paper are obtained by mixing the dye with the printable adhesive. Printed with the colored adhesive ink. Here, the printable adhesive means a liquid material that can be printed by a printing method and can exert an adhesive force by printing or the like after printing. This can be achieved by a mixture of a sealant and water.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to specific examples shown in the accompanying drawings.

FIG. 1 is an overall perspective view showing a cup-shaped paper container 1 as an example of an adhesive-assembled paper product to which the present invention is applied. FIG. 2 is a perspective view of a band-shaped base paper 2 fed from roll paper (not shown). It is a principal part top view which shows the state which printed the pattern 3 before die-cutting the cup-shaped paper container 1 based on this invention. When the pattern 3 is cut out, the cut base 2a is cut at predetermined lengths from the strip-shaped base 2, and a plurality of cut bases 2a are laminated, and the cut base 2a is cut into a cutting blade corresponding to the shape indicated by the imaginary line in the figure. Then, a large number of patterns 3 are punched at a time. The cut pattern paper 3 is formed into a cup shape to form the cup-shaped paper container 1.

As shown in an enlarged view in FIG. 3, the paper pattern 3 includes a bottom 4 serving as the bottom of the container, and a plurality of peripheral wall elements 5 extending radially from the bottom 4, that is, each extending radially outward. Is formed. At one of the circumferential edges of each of the peripheral wall elements 5, the entire surface of each of the slender triangular glue margins 6 which are portions that overlap with the adjacent peripheral wall elements 5 in a cup-formed state is shown by hatching in the figure. For example, it is printed by a gravure printing machine. In the present invention, instead of the conventional printing ink, a colored adhesive ink obtained by mixing a dye with a printable adhesive is used as the ink used for printing the adhesive margin 6. This colored adhesive ink may be one obtained by mixing a relatively small amount of water with a heat sealant as a main component and further adding an appropriate amount of dye.
Also, the printing method is not limited to gravure printing,
Various things such as offset printing, silk printing or flexographic printing are possible.

Further, a mark 7 as a mark for positioning when cutting the cut base paper 2a is formed on the strip base paper 2.
Are printed at the same time as the paste margin 6 by the same colored adhesive ink as described above. The cutting machine (not shown) is provided with a position sensor for photoelectrically detecting the mark.
Through a cutting machine to automatically detect the mark 7,
The cut base paper 2a can be cut from the band base paper 2 at a fixed position indicated by a broken line in FIG. Therefore, as described above, since each cut base paper 2a is cut at a fixed position based on the mark 7 printed simultaneously with the paste margin 6,
When a plurality of cut base papers 2a are stacked and die-cut in a single die-cutting step, a cutting line serving as an outline of each pattern 3 does not shift.

[0010] The pattern paper 3 cut out from the base paper 2 in the shape shown in Fig. 3 in this manner is placed around the bottom 4 and each peripheral wall element 5 around the bottom 4 with the edge of the bottom 4 as a bending line. Fold it up to 4
Next, the margin 6 of each peripheral wall element 5 is overlapped with a part of the adjacent peripheral wall element 5 to form a cup. Then, the respective superposed portions corresponding to the glue margins 6 of the respective peripheral wall elements 5 are adhered by heat and pressure to form the cup-shaped paper container 1 as shown in FIG. As described above, according to the present invention, the operation of applying the adhesive, which has been a problem in the past, can be easily and accurately performed by printing, and therefore, a series of these steps can be easily automated.

The material of the paper according to the present invention is not limited to a specific material, but may be any as long as it can print colored adhesive ink obtained by mixing a dye with an adhesive. For example, the present invention can be applied to a corrugated cardboard. In this case, the pressing force and the pressing time for bonding the adhesive margin may be increased as compared with those of thin paper. Also, the means for bonding the adhesive margin is not limited to thermocompression bonding, but can also be performed only by compression bonding.

[0012] Further, since the adhesive is printed only for the margin by the printing method, an extra area other than the adhesive surface is applied to the adhesive applied by the conventional hand coating or the mechanical coating. Unnecessary application to places can be suitably eliminated. In addition, since the printing location is colored, if a printing error occurs due to a malfunction of the printing machine, etc., the printing error can be easily inspected. Such defective products can be easily detected.

According to the present invention, the present invention is not limited to the above-mentioned cup, but can be applied to, for example, envelopes, paper bags and dish-shaped paper containers in general. Examples of each pattern (expanded view) are shown in FIGS. Are shown below. In the envelope pattern 8 shown in FIG. 4, similarly to the above-described specific example, the paste margin 8 shown by hatching in the figure is used.
a was cut out by printing using a colored adhesive ink in the same manner as in the specific example. Then, the envelope is folded at a predetermined bending line, and the adhesive margin 8a is heated and pressed to form an envelope.

Further, the paper bag pattern 9 shown in FIG. 5 is also formed by printing a glue margin 9a on a portion indicated by hatching in the figure using colored adhesive ink in the same manner as in the above-mentioned specific example. is there. Then, similarly to the above-mentioned envelope, the paper bag is formed by folding at a predetermined bending line, and heat-pressing the glue margin 9a.

The dish-shaped paper container 10 shown in FIG.
In the figure, a paste 9a is printed by using colored adhesive ink in the same manner as in the above-mentioned specific example, and is die-cut in the area indicated by hatching. Then, similarly to the envelope, the sheet is folded at a predetermined bending line, and the glue margin 10a is heated and pressed to form a dish-shaped paper container.

[0016]

As described above, according to the present invention, an adhesive can be accurately provided at a predetermined position and in a range of a pattern without relying on hand coating, and a base paper for a pattern having a predetermined size can be formed from a band. Can be printed using the same colored adhesive ink as the margin for glue, and the adhesive application and mark printing can be performed simultaneously, and automation can be easily performed. Further, since the adhesive is applied by printing, thin paper can be used as compared with hand-painted or machine-painted, and various kinds of base paper can be used. In addition, in the case where the conventional adhesive itself is mechanically applied, the defective rate can be extremely reduced because printing is performed against excessive defective products due to uneven application amount. Therefore, the manufacturing cost can be greatly reduced, the finish can be beautiful by uniformizing the amount of the adhesive applied, and in the case of relatively thin paper, the color of the adhesive surface can be seen from the surface. By adding a suitable value, the added value of the adhesively assembled paper product can be improved. Furthermore, since the colored adhesive ink completely dries after printing, the base paper for pattern paper can be stored for a long time, so that it is easy to handle and
Since they can be conveyed in a stack, they can be easily conveyed by physical distribution.
