Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention mainly relates to a file suitable for detachably binding and organizing and storing booklets such as pamphlets and magazines.

(Prior Art) For this type of file, a file of perforated booklets sandwiched between a front cover and a back cover and bound with a binding string is widely used as an orthodox type. ing. However, this type is inconvenient to make a hole in the booklet, and each time the booklet is bound, the knot of the binding cord must be unfastened, the back cover must be removed, and the booklet must be bound together with the new booklet.

Therefore, the applicant has provided a file having a simple structure in which an adhesive tape is attached to the inner surface of the spine cover and booklets are attached to the adhesive surface for binding. However, this file has a problem that the spine width is larger than the thickness of the bundle of booklets in the middle of binding in order to maintain a constant width of the spine cover, and it takes extra space when standing on a bookshelf, etc. There were problems such as stable storage and difficulty in stacking.

Therefore, the present applicant made further improvements and considered a file (Jpn. Pat. Appln. No. 1-78077 (Jpn. Pat. Appln. No. 3-19085)) in which the width of the spine cover can be changed according to the number and thickness of booklets bound.
As a main example of this file, a file having a structure as shown in FIG. 5 is disclosed. In this product, the adhesive surface c of the adhesive tape b attached to the inner surface of the spine cover a is covered with a separator e having a perforation d of a certain width along the length direction, and the thickness of the booklet f Peeling off only the necessary width determined by the unit of spacing of perforations d according to the number,
The booklet f is attached to the exposed adhesive surface. In this file, after binding the booklet f, the back cover g is similarly attached, and the spine a is folded in accordance with it and arranged in a book form.

(Problems to be solved by the invention) However, the booklet f to be bound with the space between the perforations d
However, in this case, as shown in FIG. 5, even if the back cover g is attached to the position indicated by the imaginary line after binding the booklet f, a part of the adhesive surface c still remains. It will be exposed without being attached. Therefore, depending on how the spine cover a is folded along the outer surface of the back cover g, the exposed surface of the non-adhesive is stuck to the lower part of the outer surface of the back cover g and is hard to remove, or the exposed surface of the unadhered is left as it is. Therefore, there is a problem in that dust or the like adheres to the adhesive tape b to lower its adhesive strength. Further, when the width of the booklet f and the width of the adhesive surface c are substantially equal to each other, the back cover sheet g is less likely to be attached to the adhesive surface c and is easily detached.

Therefore, in order to alleviate these problems to some extent, it is possible to narrow the distance between the perforations d. However, if the spacing is too small, the separator e portion to be peeled off may be broken in the middle or the adjacent portion may be partially torn and removed, and the above problems cannot be solved.
It is also conceivable that the lower edge portion of the back cover may be subjected to a mold release treatment so as to be temporarily adhered to the adhesive surface and replaced with a separator.

Therefore, the present applicant should improve the drawbacks of the prior invention by further devising the shape of the separator and the combination of the separator and the spine cover or the back cover while having the advantages of the above-mentioned prior invention. The purpose is to provide files that can be saved at low cost.

(Means for Solving the Problems) In order to achieve the above object, the present invention has an adhesive tape attached to the inner surface of a spine cover that is continuous with the front cover, and the adhesive surface of the adhesive tape has been subjected to release treatment. It has a file body covered with a separator and a back cover held on the spine so that it can slide along the surface of the separator, and the spine can be folded along the outer surface of the back cover. It is what

(Function) The adhesive tape has its adhesive surface covered with a separator, and is adhered to and integrated with the inner surface of the spine cover to form a file body. Since the surface of the separator that faces the adhesive surface is subjected to release treatment, the necessary parts can be easily peeled off from the adhesive tape without leaving foreign matter on the adhesive surface without lowering the adhesiveness, and the unnecessary parts are temporarily bonded. By covering the adhesive surface in this state, it is possible to prevent dust from adhering to reduce the adhesive strength.

When using the file of the present invention in which the back cover is held on the back cover, first determine the width of the booklet of the brochure or magazine to be bound by applying it from above the separator in advance, and the back cover is By sliding along the surface of the separator to the booklet sticking scheduled position, the inner edge of the back cover faces the position where the separator should be peeled for sticking the booklet. The maximum peeling position of the separator, which is peeled to expose the surface, can be correctly regulated to the planned sticking position.

Also, the back cover that regulates the peeling position of the separator is located along the back of the booklet bound between the front cover and the back cover as it is, and along the back of the booklet along the part that protrudes from the binding width of the spine booklet. By folding it into a book shape, it can be finished into a book shape, and the entire back width is adapted to the volume of the bound booklet.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

In the file of this embodiment, a file body 4 is constituted by a front cover 1, a back cover 2 continuous with the back cover 2, an adhesive tape 5 attached to the inner surface thereof, and a separator 6 covering the same, and It holds the back cover 3.

Each of the covers 1 to 3 is made relatively thick from thick paper or plastic sheet. The spine cover 2 is formed on its inner surface with bending grooves 2b press-formed at regular intervals along the length direction, and has a bending piece 2a on one side. The back cover 3 has a long hole 3a for sliding in the lower half thereof, and as shown in FIG. 2, the shaft portion 7a of the tack 7 attached from the outer surface of the bent piece 2a.
Then, by attaching a retaining washer 8 attached to the slide long hole 3a from its inner surface to the folding piece 2a of the spine cover 2.
Is held via the separator 6. By this holding, the back cover 3 is folded along the surface of the separator 6 and the folded piece 2a
From the inner surface, slide on the surface of the separator 6 on the inner surface of the spine cover 2. The folding piece 2a is set to a width such that the sliding long hole 3a is exposed even when the back cover 3 is slid over the spread and the booklet 9 is not exposed through the long hole 3a. Further, the slide long hole 3a is opened in a length corresponding to the width of the spine cover 2 to which the adhesive tape 5 is attached, and the booklet 9 is bound in the full width of the adhesive tape 5 as shown by the phantom line in FIG. At this time, the tack 7 comes to be located at the inner end of the long hole 3a.

The adhesive tape 5 is made of a highly elastic foam material, cloth, paper, or other base material impregnated with an adhesive agent, or an adhesive layer provided on both sides, and its surface is the adhesive surface 5a. One edge of the booklet 9 such as a pamphlet or a magazine is attached to the. In this embodiment, the adhesive tape 5 is provided shorter than the length of the spine cover 2 so that the booklet 9 can be easily attached and detached and the cost can be reduced.

The surface of the separator 6 corresponding to the adhesive surface 5a of the adhesive tape 5 is release-processed and is affixed to the adhesive surface 5a in a temporary adhesive state, and the adhesive surface 5a is protected from dust and dirt to improve the adhesiveness. I try not to damage it. A finger hook 6a is provided at the end on the front cover 1 side so that it can be easily handled when repeatedly attached to and detached from the adhesive surface. On the other hand, the end portion of the separator 6 on the back cover 3 side is interposed between the back cover 3 and the back cover 2 at the same time when the back cover 3 is held, and the booklet 9 is provided on the final surface of the adhesive surface 5a.
It is held in that position until the binding is completed. After the booklet 9 is bound, the tack 7 and the washer 8 can be easily removed, so that the back cover 3 can be removed and the entire separator 6 can be removed and discarded.

Since the adhesive surface 5a retains the adhesive force even after the booklet 9 is adhered once and peeled off, it is possible to re-bind the bundle of booklets 9 after binding to the final surface. At that time, if the separator 6 is held on one side as described above, it will not be lost even after the entire surface of the adhesive surface 5a is exposed, and it can be reattached and used as a separator for reuse of the adhesive surface 5a. It is convenient and convenient. Also, if the separator 6 is not held on one side as in the present embodiment but is set to cover only the final end of the adhesive surface 5a, the back cover 3 is not removed after the booklet 9 is bound. Can be easily discarded.

 The method of using the file of this embodiment will be described below.

First, the width of the booklet 9 to be bound is set in advance by applying it from above the separator 6, and the back cover 3 is slid along the surface of the separator 6 until the booklet 9 is to be attached. The inner edge is made to face the separator 6 at a peeling position for sticking the booklet. Then, as shown in FIG. 4, the maximum peeling position of the separator 6 which is peeled off so as to expose the adhesive surface 5a by the inner edge 3b of the back cover 3 is regulated to the planned sticking position, and the booklet is placed on the adhesive surface 5a. One edge portion 9 is attached along the bent edge 6b of the separator 6 and is bound in order. The back cover 3 in which the peeling position of the separator 6 is regulated in this way is at a position along the back surface of the booklet 9 bound between the front cover 1 and the back cover 3 with the booklet 9 being as it is. Then, as shown in FIGS. 2 and 3, the back cover 3 is bent along the back surface of the booklet 9 with the portion protruding from the booklet binding width of the spine cover 2 as shown in FIGS. Organize it into a book that fits the width of the bound booklet. Further, as shown by the phantom line in FIG. 3, after binding the booklet 9 to the entire surface of the adhesive tape 5, only the folding piece 2a is folded along the outer surface of the back cover 3. In this embodiment, since the back cover 3 is held by the bent piece 2a, there is no possibility that the bent piece 2a will turn over.

The present invention can be constructed in various modes other than the above-mentioned embodiments. For example, as long as the back cover 3 is held by the spine cover 2 so as to be slidable along the surface of the separator 6, the holding method is not limited to the one using the tacks and washers as described above, and The width and shape of the bent piece may be changed as appropriate depending on the holding method.

(Advantages of the Invention) Since the present invention has the above-described configuration and operation, the peeling position of the separator and accurate peeling up to that position can be performed very simply by adjusting the position of the back cover. In addition to the fact that the separator is peeled off just enough for any change in the thickness of the booklet to prevent the sticking of the booklet from occurring, the separator as in the previous invention (FIG. 5) caused by the excessive peeling. The adhesive surface of the booklet is not exposed like the one with a sticker, and the side surface of the booklet sticks to the exposed surface of the sticker, and the adhesive strength is reduced due to dust on the surface. The cost can be reduced as well as the problem can be solved.

Further, since the present invention has the above-mentioned configuration and operation, it is necessary to bind booklets between the front cover and the back cover and finish them into a book shape that fits those folds. It can be easily and quickly achieved by being folded with the spine.
