Abstract

PROBLEM TO BE SOLVED: To realize a postcard, the weight and shape of which conform to postal regulations, by employing a lightweight (or low cost) base paper by a method wherein an expected cut-off line for separating some part of the base paper, by which a strongly bonded layer is provided on the boundary of the strongly bonded layer, which is impossible to re-peel and formed in some part of the base paper. SOLUTION: The width of a first postcard part 11A is made equal to that of a second postcard part 12A, which forms a 'postcard main body'. At the right end part of a third postcard part 13A, a band-like strongly bonded layer 17, which is impossible to re-peel and at which an expected perforated cut-off line for cutting off this band-like portion, is provided. When the strongly bonded layer, which is provided at a band-like part 13a at the right end of the third postcard part, is re-peeled, the bar-like part 13a and some part (or a band-like part 12a) of the second postcard part 12A are permanently bonded together into an integral body or a 'postcard main body'. By adding the band-like part (or a residual part) of the third postcard part 13A to the two sheets or the first and the second postcard parts 11A and 12A, the sum of these parts is conformed to the prescribed weight (or 2 g) of the 'postcard main body' through supplement. As a result, a low weight base paper can be used.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a releasable postcard that can be pseudo-adhered to two opposing surfaces of a base paper with a pressure-sensitive adhesive and can be re-peeled without destroying information formed on the surfaces. It is.

[0002]

2. Description of the Related Art Conventionally, this kind of removable postcard has been disclosed in (1)
NIP (non-impact printer) printing is possible, (2) postcards (processing) are simple and secure,
(3) Because postage is cheaper than a sealed letter,
In particular, it is widely used in Japan.

[0003] In particular, consumers such as banks and other financial institutions, securities companies, and credit sales companies often send notices to customers and greatly reduce the postage. It is very attractive and spurs its spread.

[0004] Various forms of the releasable postcard are used depending on the amount of information desired by the customer, the model of the printer, and the like. Among them, the most frequently used form is called a “single-sided type” in which an adhesive is applied to both sides of a base sheet, folded into a Z-shape, and only one side is peeled off. .

[0005] On the other hand, there is a so-called "double-sided type (a type in which both sides are peelable, also called" six-sided development type "," reversible type ", etc.)" which is used by opening both sides (front and back) of the base paper. Yes, because of the large amount of information,
It has been favorably received from the market.

FIG. 3 is a front view, a back view, and a cross-sectional view showing a removable card according to a conventional example. In this re-peelable postcard 2, a first postcard portion 21 on the left side, a second postcard portion 22 serving as a central "postcard main body", and a third postcard portion 23 on the right side are connected via expected folding lines a and b. Base paper 20,
The releasable weak adhesive layer 24 formed on the surface of the second postcard part 22 and the third postcard part 23, and the releasable weak adhesive layer formed on the back surface of the first postcard part 21 and the second postcard part 22. And an adhesive layer 25 and the like.

The first postcard portion 21 has a width W1 smaller than the width W of the second postcard portion 22 and the third postcard portion 23. When the first postcard portion 21 is folded, as shown in FIG. Postcard part 21
And the expected folding line b on the back of the second postcard 22
A postcard clearing portion 26 such as a "postcard" is formed in a strip-shaped display portion formed between the two.

The front surface 21A of the first postcard portion 21 is an addressing surface serving as an exposed portion, and the front surfaces 22A and 23A of the second postcard portion 22 and the third postcard portion 23 are information printing surfaces serving as concealing portions. , The back faces 21B, 2 of the first postcard section 21 and the second postcard section 22
2B is a concealing portion, and the back surface 23B of the third postcard portion 23
Is an information printing surface serving as an exposed portion.

Back side 2 of first post card 21 and second post card 22
Reference numerals 1B and 22B denote concealing portions. In the case of the above-mentioned "single-sided type", information is not printed and re-peeling is not performed.
In the case of "double-sided type", it can be used as an information printing surface. In the former case, a strong adhesive layer that does not peel off again may be used.

[0010]

[Problems to be solved by the invention]

(Single-sided type problem) The above-mentioned conventional "one-sided type"
Generally holds about 70 to 90 kg / 46 base paper. The reason for this is that if the paper is about 70 to 90 kg / 46, the weight of the "postcard body" to which the two postcards are attached is "2 g or more" within the size determined by postal regulations. And that the weight of "the whole postcard" is "less than 6 g". To put it the other way around, in order for the postcard body to satisfy the requirement of "2 g or more", 70-90 kg / 46 paper must be used.
There is a situation.

In addition, since the base paper is premised on NIP printing, a high quality paper for NIP is generally used in consideration of the influence of heat when printing with NIP. And NIP paper is 55/70/90/1
A product such as 10 / 124.5 / 135 kg / 46 is provided by a major papermaking company, and has a certain marketability in terms of quality and cost.

That is, as described above, the base paper (NIP paper) is only 55 kg / 46 cheaper than the 70 kg / 46 paper, but the 55 kg / 46 paper is postal mail. "The postcard body is 2 g or more" when the size of the "postcard body" specified by the rules is the minimum.
Will not be able to satisfy the condition, so they will be shunned.

If the base paper can be appropriately adjusted in the range of 55 to 70 kg / 46 in consideration of the size of the "postcard body", forest resources, which are the raw material of NIP paper, will be wasted. Can be used without special order,
On the contrary, the cost may increase.

(Problem of double-sided type) On the other hand, the above-mentioned conventional "double-sided type" is designed so that three continuous surfaces of the base paper are folded in a Z-shape so that the front and back surfaces can be peeled off. The center of the three sides (second postcard)
"Postcard body" must be "2g or more",
In addition, the "entire postcard" composed of three surfaces (first to third postcard portions) including the two surfaces to be removed again needs to be "less than 6 g".

Thus, the "postcard body" is "2 g or more"
In addition, in order to satisfy the postal rule that "the whole postcard" is "less than 6 g", very high-precision management is required, including the amount of adhesive applied, the moisture content of paper, and the amount of printing and printing. This was a factor of cost increase.

In particular, when 124.5 kg / 46 is used as a standard size for the base paper, the “postcard” does not become “less than 6 g”, and 110 kg / 46 or a custom-made basis weight is used. However, the application amount had to be strictly controlled, and the practicality seemed to be insufficient.

Further, in the case of the "double-sided type", the size of the peeled surface on the front and back to be removed again needs to be smaller than that of the "postcard body". The reason for this is that the postcard identification unit 26 is a part that specifies the information items that are unique and essential to the "postcard body" of "postcard", and is originally from the "postcard body" due to the use of opaque base paper. Must also be reduced. In other words, the conventional peelable postcard has a “postcard” or “POST CA” on the back of the “postcard body”.
The letters "RD" are described (the pieces on which these are described are interpreted as "postcard bodies" as defined by the postal rules), and by narrowing the addressing surface and pressing it down, it is possible to peel both sides. Understand the postal rules.

For this reason, in the case of the "double-sided type",
When pressure-bonding in the form of continuous paper, slitting cannot be performed with a normal sealer (a machine that adjusts the clearance between a pair of rolls and presses the postcard by sandwiching the postcard in the clearance to perform pseudo bonding or bonding). Therefore, a special machine had to be newly added. In other words, there is a problem on the work that postcards cannot be formed unless both sides pass through a special slitter. In other words, the "double-sided type" slits the sprocket holes required for printing, but could not be performed with a sealer, so it was necessary to perform processing with a slitting machine in advance, so the cost was extra It was hanging.

An object of the present invention is to provide a removable postcard conforming to the postal rules in terms of weight and form, using a lightweight (cheap) base paper irrespective of a single-sided type or a double-sided type. It is to be.

[0020]

In order to solve the above-mentioned problems, a first aspect of the present invention is to provide a base sheet (10) in which a plurality of postcards having substantially the same width are connected via a folding line.
It is formed on two continuous surfaces on the front side and / or the back side of the base paper, and when the two surfaces are pressed to face each other, no substantial adhesive force is exhibited below a predetermined pressure and the pressure exceeds the predetermined pressure. Pseudo-adhesion layer (14,
15) a non-removable strong adhesive layer (17) formed on a part of the base paper;
A separation line (18) provided at a boundary of the strong adhesive layer formed on the base paper and separating a part of the base paper on which the strong adhesive layer is formed. It is a peelable postcard.

According to a second aspect of the present invention, in the releasable postcard according to the first aspect, the strong adhesive layer is formed in a band shape on any one of outer peripheral portions of the one of the postcards. It is a re-peelable postcard.

According to a third aspect of the present invention, there is provided the first or second aspect.
In the re-peelable postcard described in the above, the line to be cut is an easy-cutting line including a normal perforation or a micro perforation, and will be an opening line when the pseudo-adhesive layer is re-peeled. It is a removable postcard.

According to a fourth aspect of the present invention, in the removable postcard according to any one of the first to third aspects, the at least one postcard portion and the one postcard portion are provided with the strong adhesive layer. A removable postcard, wherein the total weight of the postcard adhered and the rest of the other postcard portion cut off by the cut line is 2 g or more.

The invention of claim 5 is the removable postcard according to claim 4, wherein the one postcard portion is less than 2 g.

[0025] The invention of claim 6 is the invention of claims 1 to 5.
In the re-peelable postcard described in any one of the above, it is provided on the surface of the remaining piece of the postcard part which is adhered by the strong adhesive layer and cut off by the planned cutting line, and clearly indicates that it is a postcard. It is a removable postcard characterized by having a postcard identification section.

[0026]

Embodiments of the present invention will be described below in more detail with reference to the drawings. FIG. 1 is a front view, a rear view, and FIG. 2 showing a first embodiment of a removable card according to the present invention.
FIG. 3 is a cross-sectional view showing a use state of the removable postcard according to the first embodiment. Note that the parts that perform the same functions as those of the above-described conventional example are given the same reference numerals at the end, and duplicate descriptions are appropriately omitted.

The releasable postcard 1 of this embodiment has a point that the width of the first postcard portion 11 is the same as the width of the second postcard portion 12 that becomes the “postcard main body”, and the right end portion of the third postcard portion 13. The second embodiment is different from the first embodiment in that a strip-shaped strong adhesive layer 17 that cannot be re-peeled is formed, and a scheduled separation line 18 such as a normal perforation or a micro perforation is provided to separate the strip.

This re-peelable postcard 1 is made of base paper 10
Is 55 kg / widely used as copy paper
Forty-six can be used. As described above, this 55 kg / 46 sheet may not meet the postal rules depending on the amount of adhesive applied, the moisture content, and the size of the "postcard body". At this point, nothing has been wasted.

This releasable postcard 1 was made to satisfy the postal rules in the following manner using 55 kg / 46 paper. The third postcard portion 13 is originally a portion that is to be peeled again. However, when the strong post-peeling portion 13a is provided with a strong adhesive layer 17 on the right end of the band portion 13a, the third postcard portion 13 becomes part of the second postcard portion 12 (band-like portion). 12a) and a permanent post card body by permanent bonding. Therefore, the band-shaped portion (remaining portion) 13a of the third postcard portion 13 includes two first and second bands.
Added to postcards 11, 12, and by their sum,
It will be replenished to the specified weight (2 g) of the "postcard body".

According to the present embodiment, it is not necessary to increase the paper basis weight more than necessary, and it has not been possible to use the paper until now. For example, in the case of a single-sided type, 55 kg / 46 NIP paper is used as the base paper. Therefore, forest resources can be used effectively and costs can be reduced.

Further, since the strong adhesive layer 17 is provided at the end of the third post card portion 13, it is possible to prevent accidental peeling during mailing or intentional peeling by a third party. It is practical.

FIG. 3 is a front view showing a second embodiment of a removable card according to the present invention.
FIG. 4 is a cross-sectional view showing a use state of the removable postcard according to the second embodiment. Note that the same reference numerals are given to portions that perform the same functions as those in the above-described first embodiment, and overlapping descriptions will be omitted as appropriate. In the removable postcard 1-2 according to this embodiment, the width of the first postcard portion 11 is “postcard main body”.
And the left end portion of the first postcard portion 11 has the same width as the second postcard portion 12 to be formed,
a on the surface of the band-shaped portion 11a, a postcard indicating portion 16 such as a "postcard" is formed.
On the back surface of a, a strong adhesive layer 17 that cannot be removed again is formed. In addition, a planned separation line 18 such as a normal perforation or a micro perforation for separating the band portion (remaining portion) 11a is provided.

According to the second embodiment, at least one side can be slit with the same width as the "postcard body", so that a standard crimping machine can be used as it is in the process. That is, since the slit width is substantially the same as the "postcard body", no special machine is required, and a conventional sealer can be used.

In the peelable postcard 1-2, a strong adhesive layer 17 is provided on the back surface at the left end of the first postcard portion 11, and the "postcard" or "POST CARD" is provided on the front surface.
4B, when peeled as shown in FIG. 4B, the central second postcard portion 12 and the remaining portion 11a of the first paper portion 11 become the "postcard body". For this reason, an irrational slit like the conventional double-sided type is not required, and a current ordinary sealer can be used, so that there is a great merit.

Further, there is no need to unnecessarily increase the paper basis weight. That is, the central second paper unit 12 is the first paper unit 11
Is strongly adhered to the remaining portion (non-removable portion) 11a, the total weight is added, and it is regarded as the "postcard body". Therefore, only the second paper unit 12 need not be less than 2 g, and the total amount of the remaining paper 11 a may be 2 g. Therefore, lightweight paper can be used, which contributes to the conservation of forest resources, and is effective. For example, although it depends on the size of the remaining portion 11a to be left in the "postcard main body", generally, 110 kg / 46 which is a standard grade as NIP paper can be suitably used.

Further, since the strong adhesive layer 17 is provided,
It is also very practical because accidental peeling during mailing or intentional peeling by a third party can be prevented.

It should be noted that various modifications and changes are possible without being limited to the embodiment described above, and these are also within the equivalent scope of the present invention. For example, in the second embodiment, a remaining portion is further provided at the right end of the third paper portion,
You may leave it on a 2nd paper part.

[0038]

As described above in detail, according to the present invention, a part of a postcard part to be peeled off is a residual part which is permanently adhered to another postcard part by a strong adhesive layer which is separated in advance by a predetermined cutting line. As a result, the remaining portion and other postcards can be integrated into a "postcard main body", so that the weight of the "postcard main body" can be designed to be included in the postal rules, and base paper with a low basis weight is used. be able to.

In the case of the double-sided type, a postcard clearing section is provided on the exposed surface of the remaining portion.
There is no need to slit into a narrow width as before,
A normal sealer can be used, and cost increase can be suppressed.
