TECHNICAL FIELD OF THE INVENTION
The present invention relates to a releasable laminated sheet having a laminated surface releasably adhered, for example, a releasable laminated postcard, a releasable laminated card, an envelope having a releasable sealing piece, and in particular, The present invention relates to a peelable laminated sheet that emits a rhythmic sound when peeled.
[0002]
[Prior art]
From the past, it has been known that sound is generated at the time of peeling in a peelable laminated sheet in which a laminated surface is peelably adhered. Particularly, in a sheet using a synthetic resin film such as a polyester film, peeling is performed. A loud peeling noise is generated by the zipping at the time. Also, sheets that emit various sounds as transmission information are known. These sheets may be provided with a sound code printing unit that prints or prints by coding the sound (for example, see Patent Document 1). A machine-readable code mark for specifying a message by a linguistic voice generated by the generating means is displayed (for example, see Patent Document 2), and a plurality of mechanical and electrical means such as a code reading device and a voice uttering device are displayed. Is used to generate a voice.

[Problems to be solved by the invention]
Since the peeling sound in the conventional peelable laminated sheet only gives discomfort as noise, when the peelable laminated sheet is applied to direct mail with notification information displayed on the laminated surface, the recipient In many cases, they are not interested in peeling the surface, and there is a disadvantage that the purpose of direct mail cannot be achieved because the notification information is not transmitted by not peeling the overlapping surface. Also, in the case of a sheet that generates sound using mechanical or electrical means, since the sheet itself cannot generate sound, the mechanical and electrical devices necessary for generating sound, such as a code reading device and a sound utterance device, are used. In a general household without means, there is a disadvantage that the sound cannot be heard. SUMMARY OF THE INVENTION An object of the present invention is to provide a releasable superposed sheet that eliminates such inconveniences and generates rhythmic sound instead of mere noise at the time of peeling.
[0005]
[Means for Solving the Problems]
In order to achieve this object, the peelable laminated sheet according to claim 1 of the present invention adheres the laminated surface so as to be peelable, and arranges a plurality of regions having different peeling easiness on the laminated surface. In this case, different sounds are produced according to the ease of separation when these regions are separated. That is, since the magnitude of the sound generated at the time of peeling differs depending on the ease of peeling, a plurality of regions having different eases of peeling arranged on the overlapping surface are sequentially peeled, thereby generating a rhythmical sound continuity. .
[0006]
Similarly, in order to achieve the above-mentioned object, a peelable lapping sheet according to claim 2 of the present invention adheres a lapping surface with a peelable adhesive and an adhesive force of the adhesive to the lapping surface. A plurality of regions having different peeling easiness are arranged by adjusting the strength of, and different sounds are emitted according to the peeling easiness when these regions are peeled. In the invention according to the second aspect, the overlapping surfaces are bonded with a peelable adhesive, so that the bonding condition of the adhesive is strengthened and the application pattern whose adhesive force is adjusted by the size of the area of the reinforced portion is improved. It is possible to generate a desired sound that differs not only in loudness but also in length.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a preferred embodiment in which the present invention is applied to a peelable superimposed postcard will be described in detail with reference to the accompanying drawings. Here, FIG. 1 is a perspective view of the superimposed postcard, FIG. 2 is a cross-sectional view taken along the line AA of FIG. 1, and FIG. 3 is an explanatory diagram showing an arrangement state of a plurality of regions having different peeling easiness.
[0008]
As shown in FIGS. 1 and 2, the superimposed postcard 1 is formed by folding an upper paper piece 3 and a lower paper piece 4 that are connected to each other at a folding perforation 2 at the folding perforation 2 and superimposing them. Normally, the surfaces are adhered by applying a predetermined pressure without being adhered, and are adhered with a pressure-sensitive adhesive 5 which can be peeled off after adhesion and can be printed and printed. Although not shown, notification information such as confidential information that is not desired to be known to others and general guidance information that does not need to be concealed is printed or printed on the overlapping surface.
[0009]
As the pressure-sensitive adhesive 5 described above, a non-peelable adhesive base that can be printed and printed and is difficult to peel off once bonded is used. Those blended are preferred. As the non-peelable adhesive base, a known pressure-sensitive adhesive may be used.Particularly, natural rubber latex obtained by graft copolymerizing styrene and methyl methacrylate on natural rubber, It is suitable in terms of blocking resistance, heat resistance, abrasion resistance and the like.
[0010]
On the other hand, as the fine particulate filler, those having a small affinity with the adhesive base, for example, zinc oxide, titanium oxide, calcium carbonate, kaolin, activated clay, spherical alumina, wheat starch, silica, glass powder, Shirasu balloon and the like. These materials may be used alone or in combination of two or more. In particular, a combination of silica and another appropriate filler is preferable.
[0011]
When applying a bonding condition to the pressure-sensitive adhesive 5 with a pressure roller (not shown), first, a pair of upper and lower first pressure rollers presses the upper and lower surfaces of the superimposed postcard 1 to cover the entire superimposed surface. The second pressing roller is formed by forming a plurality of protrusions having different sizes on one of the upper and lower rollers in the same manner. By increasing the adhesive force of the portion corresponding to the convex portion of the mating surface, the ease of peeling is reduced, and the strong adhesive region 5a which can be peeled but has a low peeling ease and has a resistance when peeling is provided. And a weak adhesive region 5b having high resistance and having almost no resistance at the time of peeling. As is clear from FIG. 3, each of the strong adhesive regions 5a is a circle having a different size following each convex portion of the second pressure roller (not shown). Then, portions other than the strong adhesive regions 5a become the weak adhesive regions 5b.
[0012]
Also, as shown in FIG. 1, address information 6 is printed on the exposed surface of the upper sheet 3 and an arrow pointing to a triangular cutout 7 provided at the lower left corner of the upper sheet 3 Please peel it off, and you will hear a fun sound. "
[0013]
Since the present embodiment is configured as described above, a finger is put on the notch 7 of the superimposed postcard 1 in the state shown in FIG. When peeling, the peeling sound at the time of peeling is larger in the strong bonding area 5a than in the weak bonding area 5b due to the difference in the ease of peeling between the weak bonding area 5b and the strong bonding area 5a, in other words, due to the difference in bonding strength. Among the strong bonding regions 5a, the strong bonding region 5a having a larger area emits a longer peeling sound longer. Therefore, according to the peeling operation, a rhythmic sound is continuously generated according to the arrangement pattern of the weakly-bonded region 5b and the strongly-bonded region 5a.
[0014]
Note that the present invention is not limited to the above-described embodiment. For example, the releasable adhesion of the superposed surfaces is performed not by the pressure-sensitive adhesive 5 but by another bonding condition such as a heat-sensitive adhesive. Adhesives that can be used or those that do not use adhesives may be used for tight compression bonding between resin films. In this close compression bonding, adjustment of the compression force (pressing force) also allows for easy peeling. Different regions can be formed. Further, the regions having different peeling easiness are not limited to the two types of the strong bonding region 5a and the weak bonding region 5b, and the peeling easiness of each of the regions 5a and 5b may be further subdivided. Further, it goes without saying that the present invention can be applied to a superimposed sheet other than the superimposed postcard 1.
[0015]
【The invention's effect】
As described above, according to the releasable laminated sheet that generates sound when peeled according to claim 1 of the present invention, by arranging regions having different peeling easiness on the laminated surface, rhythmical peeling is performed according to the peeling operation. Since the sound can be continuously generated, the overlapping surface is peeled off with an interest, and the notification information displayed on the overlapping surface can be reliably transmitted.
[0016]
Moreover, according to the peelable laminated sheet which produces a sound at the time of peeling according to claim 2 of the present invention, in addition to the above-described effects, the ease of peeling is different by adjusting the adhesive force of the peelable adhesive. There is an effect that the region can be provided easily and reliably.
