Abstract

PROBLEM TO BE SOLVED: To prevent the upper envelope paper sheet positioned at the outer periphery of a printing part in a bent state from generating a warp and obtain accurate print, smooth feed and clear printed image, by making thinner the thickness of the upper envelope paper sheet provided with a write-in part than the thickness of the lower envelope paper sheet. SOLUTION: The upper envelope paper sheet 2 and the lower envelope paper sheet 3 are superposed and the three sides are bonded with an adhesive 4 to form an envelope. These envelopes are continuously connected at the boundaries of perforations for folding and cutting purposes to constitute continuous envelopes 10. When the upper envelope paper 2 is made of paper with basis weight of 55kg for instance, the lower envelope paper 3 is made of paper with basis weight of 70kg. And hence, when an envelope 1 is fed in a printer, even if the front face side of the upper envelope paper sheet 2 is positioned at the outer periphery of a bend and bent there, the upper envelope paper sheet is prevented from warping owing to mutual shifting and hence, the envelopes can be smoothly and accurately fed and printed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an envelope for printing on a printer, and can smoothly feed on the printer.
The present invention relates to an envelope from which a clear printed image can be obtained.

[0002]

2. Description of the Related Art Heretofore, in a print envelope composed of an envelope upper paper and an envelope lower paper, the envelope upper paper and the envelope lower paper are each formed by using the same paper, that is, paper having the same paper quality. . However, in recent years, non-impact printers capable of high-speed printers have been performing a large amount of print processing.

However, when printing is performed using a conventional envelope, when the envelope is fed through the printer, the feed path is not straight, and the envelope is fed in a curved manner. If the front side is curved at the outer periphery of the curve, a distortion occurs between the envelope upper paper and the envelope lower paper at the curved portion between the envelope upper paper and the envelope lower paper, enabling smooth feeding and accurate printing. There was an inconvenience.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to propose an envelope capable of smoothly and accurately feeding and printing an envelope in a printer.

[0005]

SUMMARY OF THE INVENTION The present invention relates to an envelope comprising an envelope upper paper having an entry portion on the front side and an envelope lower paper, wherein the thickness of the envelope upper paper is smaller than the thickness of the envelope lower paper. An object of the present invention is to provide an envelope for printing characterized by having a thin configuration, and to solve the above problems.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an envelope according to the present invention will be described based on the embodiment shown in FIGS. FIG. 1 is a front plan view showing a continuous envelope as the envelope of the present invention, and FIG. 2 is an explanatory sectional view taken along line XX of FIG.

The envelope of the present invention is, as shown in FIGS.
The envelope upper sheet piece 2 and the envelope lower sheet piece 3 are overlapped, and the three peripheral portions are adhered with an adhesive 4. The envelope 1 is continuously folded at a perforation 5 for folding and cutting. It is constituted. The surface of the envelope piece 2 is provided with an entry section 6 such as an affiliation and a name. At both ends, transfer holes 7, 7 are provided for transferring the envelope.
Is provided.

The envelope upper sheet 2 and the envelope lower sheet 3 have different thicknesses, and the thickness of the envelope upper sheet 2 is thinner than that of the envelope lower sheet 3. For example, in the case where the envelope upper sheet piece 2 is formed using 55 kg of continuous paper, the envelope lower sheet piece 3 may be formed using 70 kg of continuous paper.

In the above-described embodiment, the envelope for enclosing a commuter pass for commuting, which is provided to an employee in a company or the like, is illustrated, but the usage of the envelope 1 is not limited to this embodiment. is not. Further, the envelope 1 may be in a unit shape without being continuous.

[0010]

As described above, according to the envelope of the present invention, the paper thickness of the envelope upper sheet having the writing section is made smaller than the paper thickness of the envelope lower sheet. The printing and feeding of the envelope in the curved state are also very useful, for example, accurate printing and smooth feeding can be performed without causing distortion of the envelope piece located on the outer periphery in the curved state.
