Description

  The present invention relates to a paper container made of a single mount, and more particularly to a robust paper container that is easy to assemble.

  In recent merchandise distribution, the transport amount by mail parcels has become enormous, and this trend is increasing more and more.

  Thus, this type of product is made of a resin material such as cardboard paper or polystyrene foam. The reasons for this include the maintenance of the product, ease of storing the product, repeated use, etc., such as mitigating the impact during the transportation of the product and keeping warm and cold.

  In particular, the prior art as a so-called folding container made from a paper-type mount has a central vertical fold line on the left and right side plates of the container and a 90 ° inclined fold line at the bottom thereof, and bends along these fold lines. There is an invention in which the tape can be reassembled without being peeled off (see Patent Document 1).

  In addition, it has a center horizontal fold line on the front and rear left and right side plates and an inclined fold line on the left and right side plates, and it can be reassembled without peeling off the adhesive tape attached to the container bottom by bending along these fold lines. There is an invention (see Patent Document 2).

  However, the former cardboard container is sealed by sticking the joints of the front and rear upper plates of the container lid with adhesive tape, and the subsequent dismantling is a method in which the adhesive tape is peeled off, so the cardboard container is damaged as the tape is peeled off. Will be. Therefore, even if it is used at most, it is about twice, and it is not suitable as a container that can be used many times and can be reused.

  On the other hand, the latter corrugated cardboard container is suitable as a container that can be used many times because the seam between the front and rear upper plates of the container lid is sealed with a tightening string for winding the winding tool. It is troublesome to wind a tightening string around the tool.

  In both cases, since the container lid is simply formed by overlapping the front, rear, left and right upper plates, the strength of the container lid is not sufficient. Furthermore, in the latter case, since notches and through holes for bending are formed in the left and right side plates, there is a drawback that stress is concentrated on the notches and through holes during bending and the strength of the container is lowered.

  In general, the corrugated cardboard container is thick and expensive, and is not suitable for the conveyance of simple small items. For this reason, a relatively inexpensive mount has been used. For example, the technique disclosed in Patent Document 3 is easy to assemble and dismantle, and in particular, accommodates long small items and is devised for easy removal.

  It has a front plate, a rear plate, both side plates, and a bottom surface forming piece, and a paper box body formed by folding and sticking an insertion flap and a paper blank provided with a perforation for a cut-off opening on the cover plate. In the inside, a base plate that has a base plate facing the bottom of the paper box body and a base plate that opposes the plate, and a base plate in which a stop piece is formed at the front end of the base plate is inclined toward the opening. Although there is an invention of a packaging paper box (see Patent Document 3), there is a problem in particular in terms of strength, not for the purpose of transport such as a mail parcel.

In addition, containers made of foamed polystyrene for frozen foods, etc., have serious pollution problems because they are petroleum products. It is not good at all, and has the disadvantage that it is quite expensive to make the mold.

  Next, a method for assembling the container shown in this embodiment will be described.

  Thus, first, the design of the container body drawn on the mount (1) is cut along the outline.

  Next, the following order may be appropriate. For example, the front side plate (3), the rear side plate (4), the left side plate (5), and the right side plate (6) of the container bottom plate (2), respectively. Are vertically raised along the valley fold line (7) (8) and the valley fold line (9).

  Subsequently, the left and right second left side plates (17) and the second right side plate (18) of the front side plate (3) are bent forward through the valley fold lines (19) and (20). Then, the left and right third left side plates (21) and the third right side plate (22) of the rear side plate (4) are also folded rearward and outward through the valley fold lines (23) and (24), respectively.

  As a result, since the second left and right side plates (17) and (18) and the third left and right side plates (21) and (22) have different heights, as shown in FIG. Are overlapped in the vertical direction.

  Therefore, as a result, when the storage container of the present embodiment is assembled, the overlapped portion acts like a column strong against the load in the vertical direction, and even when a plurality of such storage containers are stacked, the load can be dealt with. It was.

  In this case, the first left side plate (5) and the first right side plate (6) are connected to the second left and right side plates (17) and (18) and the third left and right side plates (21) as seen in FIG. ) It is bent downward on the outside of (22).

  Further, the first upper plate (26) is folded forward through the valley fold line (25) of the front plate (3). In this case, the fourth left side plate (29) and the fourth right side plate (30), which are located on the left and right sides of the first upper plate (26) and are connected via the folding lines (27) and (28), The left side plate (5) and the first right side plate (6) are bent so as to be wrapped around, and are placed along the first left side plate (5) and the first right side plate (6).

  Furthermore, as can be seen in FIG. 4, the second upper plate (34) is bent forward in a direction overlapping the first upper plate (26) at the valley fold line (33).

  In this case, the left and right rotating plates (39) and (40) provided on the left and right sides (35) and (36) of the second upper plate (34) are bent downward along the valley fold lines (37) and (38), respectively. The left side plate (5), the first right side plate (6), the second left side plate (17) and the second right side plate (18) are inserted and fitted.

  Further, in this case, the engaging portions (41) and (42) at the distal end portions of the left and right rotating plates (39) and (40) have their upper sides rotated when the second upper plate (34) is rotated in the opening direction. 1 The upper plate (26) can be engaged with the back surface behind it, and when the first upper plate (26) is opened, its angle is constant, such as 90 degrees. It was possible.

  In the embodiment of the present invention, there are notches (43) and (44) inward of the third left side plate (21) and the third right side plate (22). (39) The thickness and width of (40) are substantially equal, and serve as a guide for the turning motion of the rotating plates (39) and (40), so that the opening motion of the first upper plate (26) can be performed smoothly and Even when the operation of the first upper plate (26) is repeated, there is an effect that there is no fear of loss of shape.

  As another embodiment of the present invention, a part of the first upper plate (26) is cut out to form a storage port (46) for the stored material. The fitting member obtained by cutting out a part of the first upper plate (26) without causing the container body to lose its shape is located on the back surface of the second upper plate (34). (26) In the case where the part is pasted in a position that is contrasted with the blank part cut out, this fitting member serves as a so-called “plug”, and it keeps the container warm and keeps the container cool. It can be prevented in advance.

  Then, a pressure sensitive adhesive or the like is applied to the back surface of the protrusion of the first upper plate (26) or the left or right end surface or the back surface of the left and right side plates (29) and (30) of the upper plate (26). The layers (47), (48), and (49) provided in the embodiment are firmly attached to a predetermined portion of the container body in contact with the layer (47) of the pressure-sensitive adhesive or the like. It is natural to increase.

  Finally, when the insertion portion (52) is erected on the second upper plate (34), it can be inserted into the insertion hole (53) formed in the corresponding position of the first upper plate (26). It was possible to prevent the second upper plate (34) from being overloaded.
