Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is mainly mounted on a corner portion of a front cover or a back cover of a book such as a file, a notebook, a book, and a book cover, and can store a memo, a document and the like inside. At the same time, it relates to a so-called simple pocket that protects the corners of the front cover and the back cover.

[0002]

2. Description of the Related Art Conventionally, when a simple pocket is provided on the inside of a back cover such as a notebook, the back cover is made of synthetic resin, and the sheet material for the pocket is also one synthetic resin sheet. Two L-shaped sides or three U-shaped sides of the sheet material are joined to the inner peripheral edge of the back cover by heat sealing. The simple pocket portion configured in this manner can accommodate, for example, memo writing in the gap between the back cover and the portion where the pocket sealing material is not joined.

In addition, an L-shaped metal reinforcing component having a U-shaped cross section at the corner portion of the cover of a high-quality notebook, file, or the like, and the cover corner portion being inserted into the opening. Is attached to prevent damage to the corners of the cover sheet due to long-term use such as a notebook.

[0004]

Since most conventional simple pockets are joined by heat sealing, they cannot be realized unless the cover is made of synthetic resin, and the joint strength between the cover and the sheet material for pockets is limited. Therefore, if memos and the like are repeatedly taken in and out, there is a drawback that they are easily peeled off from the joint end of the simple pocket.

Further, the conventional simple pocket does not function as a reinforcing material for the corner portion of the cover, and a metal L-shaped reinforcing component is separately required for reinforcement. And
Since the corner portion reinforcing component is too expensive to manufacture, it has been limited to use in high-quality notebooks and the like.

The present invention has been made in order to solve the above-mentioned inconvenience, and an object thereof is to provide a simple pocket which can store memos and the like and at the same time also functions as a reinforcing component.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a simple pocket 1 according to a first embodiment of the present invention, and FIG. 2 is a sectional view of the simple pocket 1.

The simple pocket 1 in the first embodiment is
As shown in FIG. 1, a sheet-shaped pocket forming member 2 having a substantially right triangle, and a pocket forming member 2 extending from two adjacent sides of the pocket forming member 2 at right angles to the inner surface side of the pocket forming member 2. And a substantially L-shaped abutting portion 4 extending along the inner surface of the abutting portion 4, and the inner surface of the abutting portion 4 serves as a joining portion 5 for the object to be mounted. Further, in the present embodiment, the gusset 3 is interposed between the two sides of the pocket forming member 2 and the outer edge of the abutting portion 4 to facilitate fitting to a thick cover sheet or the like.

The pocket forming member 2 is a sheet material or a thin plate material made of a slightly thick synthetic resin having at least one surface whose inner angle is a right angle (holding object holding surface), and its hypotenuses are adjacent to each other at a right angle. It is formed from two matching sides through a curve. The pocket forming member 2 may be subjected to processing such as coloring with an appropriate color, or decorating with a design such as a character or a hologram for children. And in any case, making it transparent makes it convenient to see the contents.

On the other hand, the abutting portion 4 is made of a sheet material or a thin plate material made of the same material as the pocket forming member 2 and has an L shape having a substantially constant width, and both end portions of the L shape are It is cut so that it becomes a little curved.

The pocket forming member 2, the gore 3, and the abutting portion 4 may be formed by separately joining the cut sheet members by a joining means such as a heat seal, an ultrasonic welder, or an adhesive. You may cut | disconnect the pocket formation member 2 and the gore 3, and may join the contact part 4 to this. Further, the sheet material or the thin plate material may be integrally molded from the beginning by plastic deformation by heating, or may be integrally molded by injection molding of plastic. The gusset 3 may be provided as necessary, and the pocket forming member 2 and the contact portion 4 may be provided.
And the contact portion 4 on the edge of the pocket forming member 2.
The edges may be directly joined by heat sealing or the like.

The joining portion 5 located on the inner surface of the abutting portion 4 may have any structure as long as it has a function of joining to the object to be mounted, but in the present embodiment, it is shown by the hatched portion in FIG. The adhesive layer 6 with a certain width from the inner edge
It is formed by forming a letter shape. Then, the release sheet 7 is attached to the surface of the adhesive layer 6. When this release sheet 7 is attached, as shown in FIG. 2, a part 7a of the release sheet 7 is attached to the adhesive layer 6, and the remaining portion is the joint between the contact portion 4 and the pocket forming member 2. Turn back at the side,
It is desirable to set the folded-back portion 7b to be longer than the attachment portion 7a so that the end 7c of the folded-back portion 7b projects toward the front side (opposite to the fold) of the end portion of the attachment portion 7a. . By doing so, it is possible to eliminate the inconvenience that the adhesive layer 6 is inadvertently attached to the cover or the like before positioning when the simple pocket 1 is mounted.
Note that this operation will be described later.

Next, the operation of mounting the simple pocket 1 having the above-mentioned structure on a notebook such as a notebook or a file will be described.

When the simple pocket 1 is attached to the back cover 9 of the notebook 8, for example, the pocket forming member 2 is attached to the back cover 9.
The contact portions 4 are positioned on the inner surface side of the back cover 9 respectively, and in this state, as shown in FIG. 2, the corners of the back cover 9 are located between the pocket forming member 2 and the contact portions 4. Insert the corner 9 '. At this insertion stage, the release sheet 7
Since it is still attached, the adhesive layer 6 can be smoothly inserted without accidentally adhering to the back cover sheet 9. When the back cover 9 reaches a sufficient depth, for example, when the back cover 9 is inserted until the two sides of the back cover 9 come into contact with the gusset 3, the protruding end 7c of the folded-back portion 7b of the release sheet 7 in this state. Pick it with your finger and pull it out (in the direction of the arrow in Fig. 2). When the folded-back portion 7b of the release sheet 7 is pulled to the front, the release sheet 7 is sequentially peeled from the inner part of the attachment portion 7a, and finally the release sheet 7 is completely peeled from the adhesive layer 6 to expose the adhesive layer 6. . When pressure is applied to the back cover 9 side of the adhesive layer 6 in this state, the simple pocket 1 is attached to the back cover 9 of the notebook 8 by the adhesive force of the adhesive layer 6.

When the simple pockets 1 are mounted on the respective corners of the front cover 10 and the back cover 9 by repeating the mounting operation as described above, each of the front cover 10 and the back cover 9 is attached as shown in FIG. The corner portion is covered with the simple pocket 1. Therefore, the notebook 8 can be used to prevent the corners of the front cover 10 and the back cover 9 from being damaged even if an object hits them.

Further, as shown in FIG. 4 (b), the back cover 9
Since the pocket forming member 2 of the simple pocket 1 forms a pocket between the inner surface of and the inner surface of the back cover 9, the memo paper 11 or the address book is inserted into the gap between the pocket forming member 2 and the back cover 9. It is possible and convenient. Therefore, when the simple pocket 1 is attached, the usability of the notebook 8 can be improved. Further, when the memo paper 11 or the like is inserted into the pocket, since no portion of the simple pocket 1 is attached to the inner surface of the back cover 9, there is no protruding portion to be caught and the insertion can be smoothly performed. In addition,
A similar pocket can be formed on the inner surface of the front cover 10, and a business card, memo paper or the like can be smoothly stored therein.

Although the pocket forming member 2 of the simple pocket 1 in the first embodiment is a substantially right triangle, the present invention is not limited to this. For example, as shown in FIG. 5, a portion that was a hypotenuse, that is, a portion that is diagonal to the contact portion 4 may have an arc shape. By doing so, the area of the pocket forming member 2 is increased, and the main object can be stably accommodated even if it is relatively large. Further, the pocket forming member 2 may be a rectangle as long as it is a little smaller than the width of the cover sheet or the like.

Further, the adhesive layer 6 is, as shown in FIG.
The pocket forming member 2 may be provided in addition to the inner surface of the contact portion 4. The adhesive layer 6 ′ provided on the inner surface of the pocket forming member 2 is formed in a strip shape along the two sides of the pocket forming member 2 which are orthogonal to each other. When the simple pocket 1 is attached, the cover sheets 9 and 10 may be sandwiched between the two adhesive layers 6 and 6'and fixed.

The present invention is not limited to the above-mentioned notebook, but can be applied to various books. A book is a broader concept than a booklet, including files, notebooks,
Books, book covers, notebooks, etc. that have a cover or a portion equivalent thereto and have leaves such as pages bound between them (booklets), as well as those that are not bound (for example, files) Means a concept that also includes. Also,
It can be attached not only to books but also to other things such as a clipboard. In short, the pocket forming member 2
Any object having a corner portion that can be inserted between the contact portion 4 and the contact portion 4 can be attached. And
The gusset 3 having an appropriate width may be formed according to the thickness of the corner portion.
