DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a cover plate containing a core material which can be used as a cover of a pencil case, an accessory case or the like, or a cover of a filing tool such as a loose leaf binder.

[0002]

2. Description of the Related Art A cover of a filing tool such as a pen case, a small case, or a loose leaf binder which has been conventionally used usually has at least a relatively thick paperboard as a core material. Used. The outside of the paperboard is covered with a cover. The prior art will be described in detail by taking a pencil case lid as an example.
As shown in the figure, the outside of a paperboard A 'as a core material is covered with a cover B'. However, simply covering the outside of the paperboard A 'as the core material with the cover B' lacks elasticity. In the case of a pencil case lid, it is particularly required to have elasticity, and it is desirable to have a rounded shape around the lid. Therefore, as shown in FIG. A sheet C ′ made of urethane is usually overlapped as a cushioning material on a portion corresponding to the lower side), and two outsides of the paperboard A ′ and the sheet C ′ are covered with a cover B ′.

[0003] As seen in this lid, the surface plate is made of paperboard A '.
And a flexible sheet C 'and a cover B' for covering both, the paperboard A 'and the sheet C' are completely different from each other. When covering with B ', the overlapping paperboard A' and sheet C 'may be displaced, and it is necessary to temporarily attach the sheet C' to the paperboard A 'in advance in order to prevent this, and the operation is unexpectedly complicated. There is a disadvantage that there is. On the other hand, clocks, desk calculators, skeletons often seen in telephones, etc., like see-through products, there are times when you want to see through the surface plate, but if paperboard is used as the core material as in the past However, it is not possible to see through what is inside it through the front plate. The present invention seeks to overcome all of the disadvantages of the prior art by developing a new alternative to paperboard that has been conventionally used as a core material.

[0004]

In order to achieve the above object, the present invention comprises a core and a cover for covering the outside of the core.

BEST MODE FOR CARRYING OUT THE INVENTION
This will be described in detail with reference to the accompanying drawings. FIG. 1 shows an example in which the present invention is applied to a pencil case lid. The areas indicated by F ₁ , F ₂ and F ₃ in the lid shown here are parts to which the present invention is applied. That is, the partial area F ₁ of Figure 1 is indicated by f ₁ in FIG. 2, the partial area F ₂ of Figure 1 is indicated by f ₂ in FIG. 2, region F ₃ in FIG. 1 are indicated by f ₃ in FIG. 2 correspond respectively to the part, f _1, f _2, f ₃ portions and front and back two cover as shown in Figure 1 and the back plate portion f ₄ which is located between the successive f ₁ and f ₃ to f ₃ It was covered with 3, 3 to make one lid.

[0008] In the portion of the f _1, f _2, f ₃ in FIG. 2, a tray-shaped core plate 1 and the lid cover 2 is used as the core material. The tray-shaped core plate 1 has a recess
1a is formed, and a lid cover 2 is arranged on the recess 1a so as to cover this portion. The outside of these is covered with two front and back covers 3,3. Therefore, it is possible to easily produce a surface plate having a completely different form from the conventional surface plate in which an elastic material is interposed along the core material. In particular, since the tray-shaped core plate 1, the lid cover 2 covering the recess 1a, and the cover 3 covering the outside thereof are all made of synthetic resin, they can be easily manufactured by molding. Can do it, and
Since they can be simultaneously integrated by means of welding, the front plate can be produced very efficiently. In addition, when the tray-shaped core plate 1 is made of a synthetic resin when it is desired to have a round shape around the surface of the plate, the core plate 1 can be easily molded into a desired shape. Can have a natural roundness.

[0009] The f _1, f _4, a state in which the f ₂ portions covered on the front and back two covers 3, 3 in FIG. 3, FIG state of covering the f ₃ parts on the front and back two covers 3, 3 It is shown in FIG. FIG.
As is clear from FIG. 4, the recess 1a of the tray-shaped core plate 1 is formed.
By covering the upper part with the lid cover 2, a space portion consisting of the recess 1 a is formed between the core plate 1 and the lid cover 2. When the core plate 1 and the lid cover 2 are covered with the cover 3, Space acts as a kind of cushioning material. Therefore, the lid can be given an appropriate elasticity without interposing an elastic material along the core material as in the conventional case.

The cover 2 is preferably kept stationary with respect to the core plate 1. In order to do so, in the case of the illustrated example, a horizontal stepped portion 1b is provided inside along the peripheral edge of the core plate 1.
Is formed over the entire circumference, and the peripheral edge of the lid cover 2 is placed on the step portion 1b. Then, in order to fix the lid cover 2 to the core plate 1, the two are further engaged with the concave and convex. The most suitable form for this concave-convex engagement is that a plurality of protruding pieces 2a, 2a are formed on the peripheral edge of the lid cover 2 and each protruding piece 2a, 2a is
One example is insertion into the engagement holes 1c, 1c formed on the outside of 1b. However, the concave-convex engagement for fixing the lid cover 2 to the core plate 1 is not limited to the above-described case, and a plurality of navel-shaped protrusions are formed on the side of the stepped portion 1b. The protrusions may be respectively fitted into a plurality of holes formed in the cover 2.

The tray-shaped core plate 1 and the lid cover 2 can be usually made of synthetic resin. If these are made of synthetic resin, all of them can be easily manufactured by molding, and they can be integrated at the same time by means of welding. Can be. In addition, when the tray-shaped core plate 1 is made of a synthetic resin when it is desired to have a round shape around the surface of the plate, the core plate 1 can be easily molded into a desired shape. Can have a natural roundness. In particular, when the core plate 1 and the lid cover 2 are made of a soft synthetic resin, the lid can have optimal elasticity in combination with its own elasticity. Examples of the synthetic resin include polypropylene,
However, the present invention is not limited to this. Further, it is preferable that the recess 1a of the core plate 1 is made shallow to make the entire core plate 1 as thin as possible. Further, it is preferable that the lid cover 2 disposed on the recess 1a is made as thin as possible. When the core plate 1 and the cover 2 are made of synthetic resin, it is extremely easy to make them as thin as possible.

When the tray-shaped core plate 1 and the lid cover 2 are made of synthetic resin, and the front and back covers 3, 3 covering the outside are made of vinyl chloride, they are heat-sealed. The whole can be integrated. When each component is made of a material suitable for heat sealing as described above, the lid can be manufactured efficiently and is suitable for mass production. In FIG. 1, a portion indicated by fine dots is a heat sealing portion,
By heat-sealing the portion, a lid containing a core material composed of a tray-shaped core plate 1 and a lid cover 2 can be obtained.

Further, a tray-shaped core plate 1, a lid cover 2 disposed on the recess 1a thereof, and a cover 3 covering the whole thereof
Is preferably made of a transparent material such as transparent or translucent. This way,
The lid can be seen through from the front side, and in the case of a pencil case, the pencil, ruler, eraser and other things contained in the case body can be checked through the lid. In recent years, in the case of skeletons and see-through products such as watches, desk calculators, and telephones, it is common practice to use a material that can see through the outside covering so that the contents can be seen from the outside. In this case, by forming the tray-shaped core plate 1, the lid cover 2 disposed on the recess 1a thereof, and the cover 3 covering the entirety thereof from such materials, a pencil case as a skeleton or a see-through product It becomes the most suitable as a lid.

FIG. 5 shows a pencil case using this lid. The pencil case shown in FIG. 5 is a so-called double-ended type. That is, each housing portion 4a, 4a are formed on both sides of the case body shown in reference numeral 4 in FIG. 5 (upper and lower surfaces of the drawing), of the two housing parts 4a and 4a of the sheet-like lid F ₁ portion and F _Two
It is a form that is covered with a part. Then, the engaging the F ₄ portion of the lid corresponding to the back plate portion f ₄ to the side surface portion of the case body 4, fittings 5,5 attached to opposite ends of the lid
Can be adsorbed on the adsorption plates 6 attached to both sides of the case body 4. As shown in FIG. 5, a small storage portion 4b is formed adjacent to a large storage portion 4a on one side (the upper surface in the drawing) of the case body 4, and this storage portion 4b is formed by a sheet-like lid F _3. It is made to cover with a part. And, so that can be adsorbed to the adsorption plate 8 fitted with a bracket 7 attached to the end of the F ₃ parts of the lid in a small housing portion 4b side of the case body 4.

In the pencil case shown in FIG. 5, a pair of left and right engaging grooves 9 and 9 are formed on the inner wall surface of the small storage portion 4b of the case body 4, and the two engaging grooves 9 and 9 are formed in the pair of engaging grooves 9, 9 respectively. The left and right ends of the accessory piece 10 can be inserted. A part 4c of the case body 4 into which the accessory piece 10 is inserted is made transparent or translucent so as to be at least transparent, and a name tag 11 is attached to the part 4c of the small storage part 4b.
Then, by inserting the left and right ends of the accessory piece 10 into the engagement grooves 9, the owner's name written on the name tag 11 can be seen through from the front side of the pencil case.

Although the embodiment described above shows an example in which the present invention is applied to a lid of a pencil case, the present invention can also be applied to a lid of a small case other than the pencil case shown here. . In addition to the lid of the accessory case, the present invention can be applied to, for example, a cover of a filing tool such as a loose-leaf binder. Also in this case, it is possible to easily produce a cover completely different from the conventional cover in which an elastic material is interposed along the core material. In particular,
The tray-shaped core plate 1, the lid cover 2 covering the recess 1a, and the cover 3 covering the outside thereof are all made of synthetic resin, so that they can be easily manufactured by molding. As a result, the cover of the filing tool can be produced very efficiently. Also,
The cover of the filing tool has a moderate elasticity according to the same principle as that of the cover of the pencil case, and the cover attached to the cover can be covered with the cover.

Even in the case of the cover of a filing tool, if the tray-shaped core plate 1 and the lid cover 2 are made of a synthetic resin, and especially if they are made of a soft synthetic resin, the elasticity of the material itself will be low. In addition, the cover of the filing tool can be made to have optimal elasticity, and the filing tool can be covered with the cover. Also, in the case of the cover of the filing tool, if the tray-shaped core plate 1, the lid cover 2, and the cover 3 are made of a transparent material such as transparent or translucent, the cover can be viewed from the front side. Since it is possible to see through, it is possible to see through the inside of the filing tool from the front side.
