【Example】

 Hereinafter, the present invention will be described with reference to the drawings based on embodiments. FIG. 1 is a perspective view showing a first embodiment of the present invention. The postal tool includes a storage container body 2 and a sheet body 1. The storage container body 2 includes a storage portion 21 in which small articles to be mailed can be stored. The shape of the accommodating portion 21 can be various shapes such as a quadrangle, a circle, and a star shape, and as will be described later, any shape can be given when molding with a mold. An adhesive layer P is provided on the mouth 22A of the storage container 2 (herein, the mouth means the upper surface of the side wall 22) and is adhered to the sheet body 1 described later. The pressure-sensitive adhesive may be of any type as long as it can be firmly fixed after the release paper is peeled off, as will be described later.

On the other hand, on the pressure-sensitive adhesive layer P at the mouth, a release paper R that can be easily peeled is temporarily attached. The release paper R is preferably provided along the portion of the pressure-sensitive adhesive layer to be slightly larger than the width of the pressure-sensitive adhesive layer P. Specifically, when the release paper R is made to stick out from the mouth portion 22A to the outside, it is easy to pick it with a finger or the like when peeling it off. The storage container is made of cushioning material with a relatively high cushioning property so as not to damage the small items placed inside. As the material used for the cushioning material, the foam is optimal from the viewpoint of heat insulation and water resistance, and examples thereof include foamed polyethylene, foamed polypropylene, and foamed polyethylene.

Further, cork material, which is a light wood, and corrugated paper can also be used, but the material is not limited to these. When a foam is used, as will be described later, a storage container having a storage portion can be molded at once by foam molding, which is advantageous in terms of cost. On the other hand, the sheet body 1 preferably has the same size as a postcard, and the surface thereof is a portion where characters such as an address and a name of a recipient can be written, that is, a character writing portion. However, as shown in the figure, it is also possible to print the part where stamps are attached and the frame where the postal code is entered. If the size of the sheet is larger than the official postcard (approximately 10 x 14 cm), the length is within 23.5 cm, the width is within 12 cm, and the thickness is within 1 cm. It is equivalent to the fixed form of seed mail and is advantageous from the viewpoint of postage.

As the sheet body 1, postcards that are generally sold are suitable, but synthetic paper may be used, or naturally a synthetic resin sheet having water resistance and high tear strength may be used. In that case, it may be difficult to write letters on the surface, and it is possible to add thin paper that is easy to write letters to the surface of the sheet. Now, when mailing the above-mentioned mailing equipment, first, write the address etc. in the character writing portion of the sheet body 1 and affix a predetermined stamp. Next, a small article is put in the storage portion 21 in the recess of the storage container body 2. After the completion of the insertion, the release paper R temporarily attached to the adhesive layer P at the mouth of the storage container body 2 is removed.

Here, the release paper R can be easily removed from the mouth portion by sticking the fingers with the fingers and pulling when the release paper R sticks out from the periphery of the mouth portion 22A of the storage container body 2. The sheet material 1 is positioned so as to exactly match the storage container body 2, and is strongly pressed against the adhesive layer P of the mouth portion 22A of the storage container body 2. The storage container body 2 is completely sealed by the sheet material 1 at its entire mouth, and is ready for mailing. It is to be noted that the opening is facilitated by providing a claw groove T at the corner of the mouth of the storage container body 2 as shown in FIG. The shape of the claw groove T is sufficient if there is room to insert the fingertip.

FIG. 2 shows a second embodiment of the present invention. The difference from the first embodiment is that the adhesive layer P is provided at the mouth of the storage container body 2 in the first embodiment, whereas it is provided on the sheet material here, and The main difference is that reinforcement paper is attached to the body. The surface of the sheet material is a character entry part, that is, a part (letter entry part) where characters such as the address and the name of the addressee can be entered, and the size is the same as a postcard. There is. An adhesive layer P is provided on the back surface of the sheet body 1 at a position where the mouth of the storage container body 2 abuts.

A release paper R is attached to the adhesive layer P of the sheet 1. Although the release paper R is sufficient for the width of the adhesive layer P, it is preferably wider than the adhesive layer P. This is because it is easier to pinch the release paper when peeling it off. Specifically, the size is set so as to slightly extend outside the periphery of the sheet body 1. Therefore, when the release paper R is peeled off from the sheet body 1, the protruding portion may be grasped with a finger and pulled. However, it is also possible to provide the release paper so as to cover the entire sheet body. On the other hand, the storage container body 2 is made of foam, which is one of the cushioning materials, and has a storage portion at the center.

In order to further strengthen the storage container body 2 made of foam, a reinforcing paper K1 is attached to the bottom of the storage container body 2. The reinforced paper includes plastic materials and the like in addition to papers. In order to manufacture this storage container body, it is more advantageous to use a pressing die, which will be described later, to press and form a foam material in which the foam is attached to the substrate paper. Now, when mailing the above-mentioned postal equipment, first, write the address and the like in the character writing portion of the sheet body 1, and then affix a predetermined stamp. Next, a small article, for example, a tape or the like is put into the hollow storage portion of the storage container body 2. After finishing the insertion, the release paper R attached to the adhesive layer P on the back surface of the sheet material is peeled off.

Here, the release paper R can be easily removed from the sheet material by grasping the portion protruding from the periphery of the sheet material with a finger and pulling it. The pressure-sensitive adhesive layer of the sheet material 1 is positioned so as to exactly fit the mouth portion 22A of the storage container body 2, and the sheet body 1 is strongly pressed against the mouth portion of the storage container body 2. The sheet body 1 is attached to the opening 22A of the storage container body 2, so that the so-called storage container body is sealed with the sheet material and can be mailed as it is. It should be noted that, as shown in FIG. 2, if a claw groove T that is obliquely cut is provided at a part of the opening of the storage container body 2 in preparation for opening after mailing, it becomes easy to open.

FIG. 3 shows a third embodiment of the present invention. 1 and 2 is an example in which the sheet body 1 and the storage container body 2 are separate bodies. In this embodiment, the sheet body 1 and the storage container body 2 are joined by a hinge. There is something. FIG. 3A shows a cross section of the mail device in an open state, and FIG. 3B is a top view thereof. The sheet body 1 is integrally attached to the side surface of the storage container body 2 via a hinge 3. The storage container body 2 is made of foam to which the substrate paper K2 is attached, and has a storage portion 21 which is a recessed portion, and this storage portion 21 is a storage portion of the entire storage portion when it becomes a postal tool. This is the part that occupies half.

A portion of the side wall 22 of the storage container body 2 connected to the hinge 3 forms a trapezoidal cross section. Further, claw grooves T are provided at two places of the mouth portion 22A of the storage container body 2. On the other hand, the sheet body 1 is also made of a foam material to which the substrate paper K2 is attached, and has a storage portion 13 which is a recessed portion, and this storage portion 13 is a half portion of the entire storage portion of the postal tool. Occupy Similar to the storage container body 2, the side wall of the sheet body 1 has a trapezoidal cross section, which is connected to the hinge. Therefore, when the hinge 3 is bent and the sheet body is superposed on the storage container body 2 (the state of the chain double-dashed line in FIG. 3), the side wall 22 of the trapezoidal cross section of the storage container body 2 and the trapezoidal cross section of the sheet body 1 The side wall 12 and the triangular hinge 3B are fitted into each other.

Further, the surface of the sheet material (the back side in the figure), that is, the surface of the substrate paper K2 is a portion (character entry portion) in which characters such as an address and a name of the addressee can be entered. The size of the sheet body is, for example, the same as a postcard. An adhesive layer P is provided at the mouth of the storage container, and a peelable release paper R (not shown) is temporarily attached to the adhesive layer P. As in the case of the storage container body of the embodiment shown in FIG. 1, the release paper R is preferably slightly larger than the adhesive layer P and has a portion protruding from the mouth 22A. As described above, when the release paper R is peeled off, the protruding portion is pinched with a finger or the like to facilitate the peeling.

It is of course possible to provide the adhesive layer at a position corresponding to the opening 22A of the storage container body 2 in the entire sheet. The sheet body 1 and the storage container body 2 are overlapped so as to face each other to form one sealed storage portion. On the other hand, the hinge 3 is a portion where the triangular portion 3B made of foam is connected to the side wall 12 of the storage container body 2 and the side wall 22 of the sheet body 1 via the board K2. The hinge is an important part that connects the storage container body and the sheet body, but it is transported as a postal tool because the storage container body and the sheet body are bonded and integrated. In terms of strength, it does not matter much. By the way, in order to manufacture the storage container body 2 and the sheet body 1 made of the above-mentioned foam, a method of pressing with a mold is adopted.

FIG. 4 shows the principle of the manufacturing method. On the lower surface of the pressing die 5, for example, a storage container body part 51 for forming the storage container body 2, a hinge mold part 53 for forming a hinge, and a sheet body part 52 for forming a sheet body. The mold of is formed. Further, cutting blades 54 are provided on both side surfaces of the pressing die 5. The pressing die 5 is usually heated by a heating means, which further enhances the shaping effect. On the other hand, below the pressing die 5, a processing material to be molded, that is, a foam material HK in which a foam is attached to the substrate paper K2 is positioned on an anvil (not shown) or the like.

Here, the pressing die 5 is lowered and pressed on the foam material HK to form the shape of the molding of the die. At the same time, the cutting blade 54 provided on the side surface of the pressing die 5 cuts the foam material HK to form one independent mailing tool in which the storage container body, the hinge, and the sheet body are continuously integrated. Done. A postal tool as shown in FIGS. 3A and 3B is produced in this manner. The postal tool of the present invention is extremely economical because it can be manufactured by secondary processing from a foam material using a pressing die.

The storage container body 2 and the sheet body 1 have the substrate paper K2 covering most of their surfaces, so that the outer surfaces of the storage container body 2 and the sheet body 1 made of foam can be reliably reinforced. You can Further, by selecting the substrate paper K2, the desired makeup on the surface of the postal tool becomes possible. However, since the surface of the substrate paper K2 of the sheet body 1 needs to be written with the address, address, etc., it is always formed as a portion in which characters can be written. Here, when the sheet body 1 is rotated with respect to the storage container body 2 by using the hinge as a fulcrum and can be bent, it becomes a sealed container body, that is, a postal tool, as shown by an imaginary line in FIG. .

FIG. 5 is a view showing the external appearance of the mail device in which the storage container body and the sheet body are attached and sealed. The bonded postal items are normally securely sealed by the adhesive layer for safety and, on the other hand, it is usually difficult to open them when opening them. ) Are provided at two places. When there are two claw grooves T, both can be opened, and both can be opened efficiently and evenly. The claw groove T may be provided by the pressing die 5 described above, or may be provided by cutting with a knife or the like.

FIG. 6 shows a state in which the release paper is removed from the mouth of the storage container body and small articles such as the tape F are stored in the storage container body 2. The sheet body 1 and the storage container body 2 are The state before pasting and sealing is shown (the claw groove is omitted). Here, a convex portion 23 that is just inserted is provided in the rotation hole of the tape to prevent the tape from rotating. The convex portion 23 can be provided all at once at the time of manufacturing as described above, but may be attached later by adhesion. After that, the sheet body 1 and the storage container body 2 are bonded and sealed to form a closed postal tool as shown in FIG.

FIG. 7 shows a fourth embodiment of the present invention. In the postal tool shown in FIG. 3, the sheet body 1 and the storage container body 2 are substantially half-divided, and the storage parts of the two parts constitute the storage part of the postal tool. The sheet body 1 is a postal device that does not have a storage part. Therefore, this is substantially equivalent to the postal tool of the embodiment shown in FIGS. 1 and 2 in which a hinge is just provided and the sheet body 1 and the storage container body 2 are connected. However, the difference is that the foam is stuck on the substrate paper K2. FIG. 7A shows a cross section of the postal device in an opened state, and FIG. 7B is a top view thereof.

The sheet body 1 is attached to the side wall of the storage container body 2 via a hinge. The storage container body 2 is made of foam and has a storage portion 21 which is a recessed portion, and this storage portion occupies the entire storage portion of the postal equipment. A portion of the side wall of the storage container body 2 connected to the hinge 3 has a triangular recess. When the sheet body 1 is superposed on the storage container body 2 (indicated by the chain double-dashed line in FIG. 7), the triangular hinge 3A can be fitted into the recess. On the other hand, the sheet body 1 has a form in which a foamed body in a compressed and crushed state is provided in a thin layer on the upper surface of the substrate paper K2.

The surface of the substrate material K2, which is a sheet material, is a portion (character entry portion) in which characters such as an address and a name of the addressee can be entered, and the size thereof is the same as that of a postcard, for example. It has become law. An adhesive layer P is provided on the mouth 22A of the storage container body 2, and a peelable release paper (not shown in FIG. 7) is attached on the adhesive layer P. The adhesive layer P can be provided on the sheet body instead of the mouth portion of the storage container body as shown in FIG. Since the release paper is slightly wider than the adhesive layer and has a part protruding from the mouth 22A, when peeling off the release paper R, it is easy to pinch this protruding part with a finger etc. Become.

In addition, a claw groove T is provided at one place at the mouth of the storage container body 2. The manufacturing method is carried out in the same manner as the method for the pressing die as described above, and therefore will not be described in detail here. However, since the sheet body 1 does not have a storage portion, the pressing die used is one in which the entire molding portion of the storage portion of the sheet body die portion is not depressed. FIG. 8 is a view showing the outer appearance of the mail device in a sealed state. When the sheet body 1 is peeled from the storage container body 2, it can be easily peeled off by pushing the fingertip into the claw groove T and peeling it off.

FIG. 9 shows that the release paper is removed from the mouth of the storage container body 2 and a small article such as the tape F is stored in the storage container body 2. The sheet body 1 and the storage container body 2 are shown in FIG. Shows the state before and are attached and sealed (note that the claw groove is omitted). After that, the sheet body 1 and the storage container body 2 are bonded and sealed to form a mailing tool as shown in FIG. FIG. 10 shows a fifth embodiment of the present invention. In this postal tool, the storage container body 2 is adhered onto the reinforcing paper K1, and the reinforcing paper also serves as the sheet body. Therefore, the sheet body 1 and the storage container body 2 are connected via the hinge.

FIG. 10A shows a cross section of the postal device in an open state, and FIG. 10B is a top view thereof. The reinforcing paper K1 extending from the side wall 22 of the storage container body 2 forms the hinge 3 and the sheet body 1. The storage container body 2 is made of foam and has a storage portion 21 which is a recessed portion, and this storage portion occupies the entire storage portion of the postal equipment. The surface of the sheet material, that is, the surface of the reinforcing paper K1 is a portion (character entry portion) where characters such as an address and a name of the addressee can be entered, and its size is the same as that of a postcard, for example. It is a dimension.

An adhesive layer with a release paper is provided on the back surface of the sheet body 1, that is, the back surface of the reinforcing paper K1. Here, a double-sided adhesive tape is used as the adhesive layer with the release paper, and it is stored. The tape is adhered to a position where the mouth of the container abuts. As this double-sided adhesive tape, a well-known one having release paper adhered to both surfaces of the adhesive tape may be used. Peel off one of the release papers from the double-sided adhesive tape and stretch it near the four sides corresponding to the mouth of the storage container. Then, after the release paper is further peeled off, the sheet body 1 is bent from the hinge 3 and overlapped with the storage container body 2 (indicated by the chain double-dashed line in FIG. 10), so that both are securely closed.
