Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an envelope, and more particularly to an envelope whose surface is printed with information by an electrophotographic printer (non-impact printer).

[0002]

[Prior Art]

 In recent years, when paying salaries to employees from general business offices and when notifying personal information from various financial institutions to customers (reporting accumulated payments, etc.), the management information of the payee (for example, A machine-printed envelope with the recipient's name, member number, customer code, administrator's name, etc. printed on the front, with a variety of information addressed to the individual (the recipient) (for example, a pay slip or a deposit payment report) Etc.), the envelope is sealed and handed to the recipient.

As shown in FIG. 6, an envelope 1 of this type has a structure in which an envelope upper paper 2 and an envelope lower paper 3 are bonded to each other with three adhesive sides with an adhesive 4 and the remaining one side is an opening. A double-sided adhesive tape 6, for example, is provided on the sealing section 5 with the opening side edge of the envelope lower paper 3 as the sealing section 5. Then, the envelope 1 is loaded into the impact printer in a state of a continuous envelope in which a plurality of envelopes are arranged (see FIG. 2), and the recipient management information is machine-printed on the information machine-printing description section 7 on the upper surface of the envelope paper 2. After separating them into a single envelope, each envelope was filled with a document or the like containing the information addressed to the individual and sealed with the double-sided adhesive tape 6. In addition, 8 is a release paper which covers the double-sided adhesive tape.

[0004]

[Problems to be solved by the device]

 By the way, in order to improve the efficiency of such a large amount of information machine printing work including the information machine printing work of the recipient management information as described above, a high-speed printing process has recently been performed and a quiet printing operation can be performed. Electrophotographic non-impact printers (for example, laser printers) have come into use.

Therefore, it is desired to use the electrophotographic non-impact printer to perform the information machine printing operation of the recipient management information on the continuous envelope. However, since the envelope is composed of the upper envelope paper and the lower envelope paper, which are the upper and lower sheets, there is the following inconvenience. That is, as shown in FIG. 7, when the continuous envelope 9 is applied to this non-impact printer, the upper envelope paper and the lower envelope paper are overlapped, so if there is a slight gap between them, the thickness of the envelope will increase. If there is variation, the charge state on the envelope 1 (the state where the surface of the envelope on the drum side is negatively applied) becomes defective, and when this occurs in the information machine printed part of the envelope, the toner transfer is surely performed. However, there is a problem in that it causes printing blur. Further, as shown in FIG. 8, since the continuous envelope 9 is folded and sent out due to the structure of the paper feed during the printing operation, wrinkles are formed on each of the envelopes 1 of the continuous envelope 9 at the contact portion with the drum a. b occurs. For this reason, there is a problem in that a non-contact portion with the drum is formed, and the toner transfer state from the drum a becomes defective particularly on the lower end side of the envelope, and as in the above case, the printing stain occurs.

As a countermeasure against this, before the continuous envelope is set, an envelope top paper continuous form (or an envelope bottom paper continuous form having an information machine print description part) having an information machine print description part is set in a non-impact printer. It is conceivable to machine-print the information machine-printed section. However, considering that the general business offices and financial institutions are equipped with only non-impact printers that print information on the information machine printing section, new equipment and facilities for making continuous envelopes will be required. The system is not realistic. Since it is necessary for general business offices and financial institutions to temporarily store the continuous form on the envelope after printing (or the continuous form on the bottom of the envelope), efficient envelope production cannot be performed.

In view of the above-mentioned circumstances, the present invention ensures the transfer of toner and causes a printing blur when printing is performed on the information machine printed portion on the surface of an envelope using an electrophotographic non-impact printer. It is an object to prevent this from happening, and to improve the efficiency of printing work on the information machine printing section by making the most of the convenience of the electrophotographic non-impact printer.

[0008]

[Means for Solving the Problems]

 The present invention has been made in consideration of the above-mentioned problems, and is a one-sided opening type envelope consisting of an envelope top paper and an envelope bottom paper, and an envelope top paper corresponding to the information machine printed description part on the envelope surface. The above problem is solved by providing an envelope characterized in that the paper and an envelope lower paper are releasably attached to each other so as to form a sealed portion after printing.

[0009]

[Action]

 In the present invention, the envelope top paper and the envelope bottom paper of the information machine printed description part are integrated by the adhesive layer, and a proper negative charge is applied on the information machine printed description part and properly. As it comes into contact with the drum, the transfer state of the toner becomes good, and the smear of the printing paper does not occur. After printing, the space between the envelope top paper and the envelope bottom paper can be opened, and various documents can be stored inside.

[0010]

【Example】

 Next, the present invention will be described in detail based on an embodiment shown in FIGS. The same parts as those of the conventional example shown in FIG. 6 are designated by the same reference numerals and the description thereof will be omitted. The envelope 1 has an upper surface 2 of an envelope having an information machine print description portion 7 on its upper surface, and three opposite sides of an envelope lower paper 3 which are bonded to each other with an adhesive 4, and the side of the envelope lower paper 3 on the opening side is bonded. The sealing portion 5 is provided with the double-sided adhesive tape 6. As shown in FIG. 2, this envelope 1 is obtained from the form of a continuous envelope 9 in which an envelope upper paper continuous form 10 and an envelope lower paper continuous form 11 are bonded together, and as described above, this continuous envelope 9 Is loaded into an electrophotographic non-impact printer, and various types of information are printed on the information machine printing / writing section 7 of the envelope paper 2. As the adhesive, for example, ethylene-vinyl acetate resin, acrylic resin, vinyl chloride resin, vinylidene chloride resin, synthetic rubber resin, natural rubber resin, etc. can be adopted.

In the present invention, as shown in FIG. 1, each of the envelopes 1 has a three-sided adhesive described above on a portion of the upper surface of the envelope lower paper 3 corresponding to the entire back surface of the envelope upper paper 2. An adhesive layer 12 having a weak adhesive force is provided by applying the same adhesive as that of No. 4 and printing a solid or a screen on the adhesive application surface other than the above three sides. This is a method in which the adhesive is covered by printing to weaken the adhesive force, and the envelope upper paper 2 and the envelope lower paper 3 are releasably adhered to each other via the adhesive layer 12 having the weak adhesive force. At the same time, make sure that the contents of the document to be put in the envelope and cash are not visible through the printing. Such substances contained in the printing ink to suppress the adhesive force include, for example, silicone resins such as polydimethylsiloxane and polyphenylmethylsiloxane, perfluoroalkyl phosphates, and fluoroalkyl group-containing (meta- ) Fluorine compounds such as acrylate copolymers, long chain alkyl group-containing (meth) acrylate copolymers, higher fatty acid derivatives, polyethylene wax, waxes such as carnauba wax, and polyethylene, polypropylene, etc. ..

As described above, since the envelope upper paper 2 and the envelope lower paper 3 are entirely releasably adhered to each other and have a single sheet-like cross section as shown in FIG. Even when the continuous continuous envelope 9 of No. 1 is applied to an electrophotographic non-impact printer, there is no gap between the envelope upper paper 2 and the envelope lower paper 3 as shown in FIG. By contacting with the drum a, various kinds of information can be surely printed on the information machine print writing portion 7. The adhesive force of the adhesive layer 12 may be strong enough to prevent the envelope top paper and the envelope bottom paper from separating during printing, so that the envelope top paper and the envelope bottom paper can be easily attached when inserting a piece of paper into the envelope. To be peeled off.

In the above embodiment, the adhesive layer having a weak adhesive force is provided by combining with the printing, but the present invention is not limited to this, and an adhesive material having a weak adhesive force is adopted to cover the envelope paper. The envelope lower paper may be releasably attached to each other. As described above, the portion where the adhesive layer is provided does not necessarily have to be provided on the upper surface of the envelope lower sheet corresponding to the entire back surface of the envelope upper sheet. The envelope upper paper 2 and the envelope lower paper 3 may be peelably attached to each other.

Since the envelope upper paper 2 and the envelope lower paper 3 are integrated with each other with the adhesive layer 12 as described above, the continuous envelope 9 becomes an electrophotographic non-impact printer as shown in FIG. When set and printed, the envelope surface is properly charged and contacts the drum a in a proper state, causing print smearing regardless of where the information machine print mark is on the envelope surface. I will not do it.

[0015]

[Effect of the device]

 As described above, according to the present invention, the envelope is a one-sided opening type consisting of an envelope top paper and an envelope bottom paper, and an envelope top paper corresponding to the information machine printed description part on the envelope surface. Since the envelope bottom paper is releasably attached so as to form a sealed part after printing, the envelope top paper and the envelope bottom paper are integrated, and a single-cut form for an electrophotographic non-impact printer. As a result, or even when the envelope is set as a continuous form, the conventional gaps and wrinkles between the envelope top paper and the envelope bottom paper do not occur, and the information machine printed mark on the envelope surface is blurred. Various types of information can be printed without the need to do so. Therefore, it is possible to perform highly efficient printing work using the electrophotographic non-impact printer, and it is possible to obtain the effect of excellent practicality.
