Abstract

PROBLEM TO BE SOLVED: To eliminate a waste of unnecessity of a bound part by adhering cut form sheets to each other with a lightly releasable adhesive in parts of the sheets to be bound of necessary number. SOLUTION: Predetermined characters, phrases, items and columns are previously printed on sheets of cut form sheets 2 to provide an aid of filling-in the columns. The sheets 2 of necessary number are bound as one cut form set 1. In this case, at the part on a left side as one faces it, the sheets 2 are adhered to each other via paste parts 3 of a lightly releasable adhesive. As a preferred example of the adhesive to be used, an emulsion of polybutadiene can be used. In the case of using such a cut form set 1, a user fills in as prescribed, and then the sheets 2 adhered at the parts 3 are turned over one by one from above, and released.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a form, and more particularly to a method for separating sheets constituting a form.
The present invention relates to a new type of form assembly that can use the entire sheet because a part of the sheet is not separated.

[0002]

2. Description of the Related Art Forms including peeling and separation include small slips attached to a DPE bag for requesting a traveler's check, photo development and printing, and handed to a client.
There are courier slips or general copy slips. These slips are used as a “slip set” in which a required number of single slips are bound. Conventionally, when peeling or separating each sheet of these slips, the edge of the sheet is strongly bound with a wire or an adhesive, and a perforation is provided closer to the center than the bound portion, and This was done by breaking the eyes.

However, in the case of the above-described conventional peeling and separating, once the peeling and separating are performed, the bound portion becomes unnecessary, and it is wasteful and often used in a general-purpose size (A4 size). , A5, etc.), if the bound portion is removed, the size will be smaller than the specified size if the bound portion is removed. It was necessary to use paper of a size larger than the paper. Also, in order to provide a perforation, processing for that is necessary, and if separated at the perforation, the flatness of the separated portion is impaired, resulting in a defect that it is difficult to align and a defect that the separated side is bulky when aligned. There was also.

[0004]

SUMMARY OF THE INVENTION In the present invention, in the above-mentioned conventional slip assembling, the bound portion becomes unnecessary, and there is a problem when using sheets of general-purpose size (A4, A5, etc.). It is an object of the present invention to eliminate any of the drawbacks caused by providing perforations.

[0005]

SUMMARY OF THE INVENTION According to the present invention, among the adhesives, a light-peelable adhesive, particularly a butadiene-based adhesive, has a sufficient adhesive strength to prevent inadvertent peeling before use, and It was made by paying attention to easy peeling. The invention of claim 1 relates to a form assembling, wherein a required number of form sheets are bound, and the form sheets are adhered to each other with a light-peelable adhesive in a bound portion. A second aspect of the present invention relates to a form assembly according to the first aspect, wherein the light-peelable adhesive mainly comprises polybutadiene. Furthermore, in the invention of claim 3, in the invention of claim 1 or 2, the bonding strength of the portion bonded with the light-peelable adhesive is JIS K-6854-199.
In the T-type peeling specified in 4, 10 g / 25 mm or more
The present invention relates to a form set characterized by being 100 g / 25 mm.

FIG. 1 is a schematic sectional view showing a typical example of a form set according to the present invention. The form set 1 has a required number of form sheets 2 bound. In order to assist in the entry, each of the form sheets 2 is printed with predetermined words, items, and columns in advance. A state in which the form sheets are adhered to each other by a glue portion 3 made of a light-peelable adhesive at a binding portion on the left side as viewed. Actually, the glue portion 3 has almost no thickness, but the thickness is exaggerated here to show that the glue portion 3 exists between the adjacent form sheets 2. When the form set 1 shown in FIG. 1 is used, the form sheet 2 adhered by the glue portion 3 after a user makes a predetermined entry.
Are peeled off one by one from above.

FIG. 2 is a plan view of an example in which the present invention is applied to the bag 11.
And along the three lower sides, in the areas 12, 13 and 14 between the edge of the bag and the dashed line, sealed with a normal adhesive, the side designated by the reference numeral 15 is the mouth of the bag and the side designated by the reference numeral 16 is It is the bottom of the bag. Reference numeral 17 denotes a paper piece, which is a cross-hatched portion on the lower side of the paper piece 17, and between the paper piece 17 and the bag 11 is adhered by a light-peelable adhesive. This bag 11 is, for example,
It is suitable for use in industries that undertake photo development, printing, etc., and the bag is designed as a DPE bag, and the paper piece 17 is designed as a small voucher part to hand over to the client who requested development, printing, etc. I have. In this case, the piece of paper 17 is, for example, the upper sheet of pressure-sensitive copying paper,
The bag 11 is a lower sheet, and the clerk of the DPE shop who has undertaken the development and printing of the photograph can enter various fields, that is, the name of the client, the contact telephone number, the film type, the development or printing. After marking or filling in the relevant fields in the columns such as, baking size, surface finish (glossy, matte, silk, etc.), and finish date and time, peel off the piece of paper 17 and request it as a "copy" Pass to.

The form sheet 2 is composed of a lexical character necessary for the front side (upper side in FIG. 1) of paper such as high-quality paper, copy paper, and recycled paper.
Items, columns, etc. are printed. When pressure-sensitive copying is required, pressure-sensitive copying paper or thermal recording paper in which components for coloring are separately applied to the front and back sides of the sheet 2 can be used. Here, as the pressure-sensitive copying paper, there are several types of two-component coloring on different surfaces, and there are several types of paper, such as upper paper (paper placed on top), middle paper (intermediate except for top and bottom). There are three types: paper to be used) and lower paper (the paper to be placed at the bottom). In addition, among the pressure-sensitive copying papers, there is a paper called a self-colored paper (one that develops its own color and can be placed in any position), and can be used. As a material of the form sheet 2, a plastic or metal foil other than paper can be used depending on the use, and a foamed polyethylene terephthalate resin film, a poly-laminate paper obtained by extrusion coating a polyethylene resin, a polypropylene film, and the like can also be used. .

Here, in the glue portion 3, a light-peelable adhesive is used as an adhesive constituting the glue portion. The degree of adhesion of the light-peelable adhesive is as follows: when gluing ordinary high-quality paper, handling during shipping or transportation, without inadvertent peeling during work such as sorting by destination, In addition, it is desirable that the layers of the paper do not peel when peeled. From these viewpoints, the force required for peeling is a T-shaped peeling specified in JIS K-6854-1994. At 10 g / 25 mm to 100 g /
It is desirable that it is 25 mm.

A preferred example of the adhesive that provides such a desirable adhesive strength is an emulsion of polybutadiene. For example, it is available from Zeon Corporation as latex for ABS under the trade name "Nipol". You can do it. For example, LX-111NF, LX-111A2, LX-111
111K, LX-111J, etc. are suitable for forming the bonded part of the form set of the present invention. For light release adhesives,
Resins or fats and oils or fats and oils that are incompatible with the light-peelable adhesive, fine particles present as particles having an average particle size of 0.1 to 30 μm at room temperature, or plasticizers are used alone or in combination. By adding these, it is possible to control changes in the adhesive force over time and changes in the adhesive force due to the temperature and humidity of the adherend.

[0011] As a form set of the present invention, two examples of a multi-copy slip and a DPE bag have been described. However, the former structure can be used for a traveler's check booklet and a slip for home delivery. It is also useful when various admission tickets and lottery tickets with a serial number printed thereon are stored while maintaining the order of the numbers, and when it is desired to peel them off in order when used.

[0012]

According to the present invention, a light-peelable adhesive is used as an adhesive for forming a form, and if the adhesive is intentionally peeled off at the bonding portion, it can be easily peeled off. There is no waste of unnecessary parts,
Since it is not necessary to secure a separate place for the adhesive portion, no trouble occurs when using paper of a general-purpose size (A4, A5, etc.). In addition, in the present invention, since the perforations are not used at the time of separation in the present invention, the defects caused by the perforations are not generated.
