Abstract

(57) [Summary] [Objective] In case covers and cases that are composed of folding side frames, they can be easily assembled, the material used is reduced, and when they are molded, they can be folded.
The purpose of the invention is to improve convenience and economy in storage and transportation. [Composition] When viewed in the unfolded plane, the four folding side frames are adjacent to each other and share the base sheet, and these are also used as the folding allowances. The free end of the frame can be fixed. Then, the folding allowance of each of the four side frames is made lower than the height of each of the basic side frames to form the case cover or the case.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 It relates to the field of using the case cover and itself as a case or box.

[0002]

[Prior Art]

 In the case of paper or similar sheet-like material, there is a case where a part of the side frame is folded inward in terms of moldability, moldability, and stability of molding retention. When the material is comparatively thin and the stability in molding retention is poor, the folds of the side frame are designed to fold all over the side frame on each of the four sides, or to the flat part on the extended surface beyond that. In the case of thick corrugated cardboard, cut it into two side frames at the target position and assemble it into two side frames at other target positions, and insert the two side frames at other target positions corresponding to the entire basic depth. I am trying.

[Problems to be solved by the device]

 This invention is for the case where the material is relatively thin, and it is easy to assemble, and it is possible to save the used material, improve the economical efficiency, and make the molded product foldable. The challenge is to improve convenience and economy in storage and transportation.

[0004]

[Means for Solving the Problems]

 Adjacent parts of the four side frames that form the case or box are shared by connecting the base sheet, and the shared part of this base sheet is used as the folding allowance. The area of each side frame or the basic height or depth at the time of molding is made smaller or lower, and the free end of the side frame for fixation at the target position can be adhered or adhered to the inner surface of the side frame for fixation. It was fixed or fixed with a hook.

[0005]

[Work]

 By sharing the base material of the adjacent parts of the four side frames so that they are connected and used as a folding allowance, the side faces can be easily assembled by assembling compared to the conventional independent side frame type with a small insertion allowance. In addition, by simply fixing each free end of the fixing side frame at the target position, the adjacent fold margins will be stably formed and held, and each side frame will be stable. Even if the extension surface folding area has a smaller area than each side frame, it is possible to stabilize the mold holding.

【Example】

 An example of the embodiment will be described with reference to the drawings. FIG. 1 is a perspective view of a case cover. (A) is a case cover, (1) is a top part, (2) and (3) are side frames, (2d) is a fold line, and (4) and (5) are side frames for fixing. And (6) is a gap. FIG. 2 is a developed plan view of the case cover. The chain line in (B) is a conventional ordinary case cover, and (2a) and (3a) are the extension faces of the side frame at the target position, and the extension face ears (2c) (3c) are provided at both ends thereof. is there. (2b) and (3b) are adjacent folding allowances. (2d) and (3d) are simply creases. (4a) and (5a) are extension surfaces of the fixing side frame, and (4b) and (5b) are adjacent folding allowances, and each adjacent folding allowance shares the base material sheet in the adjacent portion. That is, (2b) is connected adjacent to (4b) and (5b), and (3b) is connected adjacent to (4b) and (5b). (4c) and (5c) respectively indicate the visco-adhesive portion at the end of the extension side surface of the fixing side frame. (6) is a gap. In the present embodiment, the folded side frame is a side frame such as (2) and (2a), (3) and (3a), (4) and (4a), (5) and (5a). And a side frame extension surface that is folded so as to be in close contact with it.

Next, an embodiment will be described. The unfolded plan view of Fig. 2 shows a state in which the top part (1) of Fig. 1 is crushed downward and unfolded. A mode of assembling this in FIG. 1 will be described. First, the extension surfaces (2a) and (3a) of each side frame are bent inward (invisible) by 180 degrees. Next, the adjacent part of each adjacent folding margin, that is, (2b) and (4b), (2b) and (5b), (3b) and (4b), and (3b) and (5b) If the part is bent inward (downward) as it is, it becomes a box shape. That is, it becomes like FIG. Inside the box-shaped object, the side surface extension surfaces (2a) and (3a) are closely attached at about half the depth (height) of the side surface frame. Bend 90 degrees with each side on the back of the top (1) as the bottom. The base sheet is folded into a triangle at each adjacent diagonal streak, and the notch at the end of the diagonal streak is in contact with the top of the triangle. The extended surface ears (2c) and (3c) of the side frame are bent at the streak portion (the location of the thin line) and are closely attached to the adjacent folding muscles. In this state, the fixing side frame extension faces (4a) and (5a) are bent inward, respectively, and the side face extension faces ears (2c) and (3c) are formed, and the formed triangles and top vertical stripes. Then, attach and fix the part that will become the wall surface that covers the extended surface end adhesively bonded part of the fixing side frame. The thus-formed product has an appearance as shown in FIG. If this is used as a tissue paper cover, the tissue paper can be taken out from the gap. If a large number of these items are to be stored, transferred, or transported, (2d) in Fig. 1 and, though not shown, the target position (3d) in (2d) should be covered with the case cover. When pressed inward and folded, it folds into a small envelope or letter. In terms of the material used, in the conventional case, the size of the chain line in Fig. 2, that is, the size of the ordinary case cover in (B) was required, whereas in the case of this proposal. Can be small, as shown, which is economical. The above shows one example of the implementation, but it is free to provide no gap (6) or fold lines and not fold. Further, the adhesive bonding parts (4c) and (5c) can of course be fixed with a stapler, eyelets, cotter pins, plastic fitting screws or the like. As an example, this fixing is performed on the side of the side frame for fixing, and the shorter side is shown in each figure, but the same can be done if the shape is the same for the longer side as in the side frame. The distinction between the short side and the long side is merely for illustration and explanation. Although the embodiment is a case cover, it is of course possible to form a case or a box in which the upper and lower parts can be fitted.

[Effect of the device]

 The base sheet is shared by adjacent parts on four sides of the case so that they can be connected, and this can be used as a folding allowance so that the free ends of the two side frames at the target position can be fixed. There are great economic effects, such as being able to mold, saving the materials used, and making the molded product foldable, making storage and transportation even more effective.
