特徴とする包装箱に係る。 The present invention has been made with the aim of eliminating such conventional drawbacks. Namely, the present invention has been developed with the aim of eliminating such drawbacks of the conventional art. A lower lid member 5 that closes the lower end opening is placed on at least one of the left and right side plates 3 and 4, and a lower lid member 5 that closes the lower end opening is placed on at least one of the left and right side plates 3 and 4 during assembly.
Supporting pieces 6, 6 supporting the left and right sides of the are connected to each other, and the supporting pieces 6, 6 protrude downward from the lower surface of the lower lid member 5 by an amount equivalent to the wall thickness when assembled to form an engaging protrusion, On the other hand, an inner upper lid member 7 is connected to at least one of the upper ends of the left and right side plates 3, 4, and outer upper lid members 8, 8 are connected to the upper ends of the front and rear side plates 1, 2. This packaging box is characterized in that both left and right sides of the support piece 6 are cut out to correspond to the planar shape of the support piece 6, and the cutouts 9 form engagement recesses.

本考案は上述の如き構造を有し、例えば第１図

このようにして得られた本考案品は第２図に示
すように折畳んだ状態で輸送、保管される。 The thus obtained product of the present invention is transported and stored in a folded state as shown in FIG.

本考案品を使用するに際しては、第２図に示す

用突部を形成している。 When using the product of the present invention, after assembling the box body in the usual manner from the state shown in FIG. This overlapped portion is fixed by applying appropriate fastening means such as adhesive tape or stapler, and the bottom cover is assembled to the screw. Since the inner surface of this bottom cover is flat, it is possible to omit laying pads. Support pieces 6, 6 protrude downward from the lower surface of the bottom cover by an amount corresponding to the wall thickness thereof, and form an engaging protrusion.

切除されており、この切除部９，９が係合用凹部
を形成している。このような係合用凹凸部として
図には矩形状のものが示されているが、その他三
角状、半円状などであつてもよい。 After the article to be packaged (not shown) is stored in the box body with the bottom lid assembled, the inner upper lid members 7, 7 and the outer upper lid members 8, 8 are sequentially closed as shown in FIG. The outer upper lid members 8, 8 are fixed using adhesive tape or the like. The outer upper lid members 8, 8 are cut out at both left and right sides so as to correspond to the planar shape of the supporting pieces 6, 6, and these cut out parts 9, 9 form engaging recesses. Although a rectangular shape is shown in the figure as such an engaging uneven portion, other shapes such as a triangular shape or a semicircular shape may also be used.

而して本考案品を段積すると、第５図から明か
なように、各段に於て、係合用凹部としての切除
部９，９に、係合用突部としての支え片６，６が
係合し、この係合により箱ずれひいては荷崩れの
危険性をなくし得る。 When the products of the present invention are stacked, as is clear from FIG. 5, in each tier, supporting pieces 6, 6 as engaging protrusions are formed in cutouts 9, 9 as engaging recesses. This engagement eliminates the risk of the box shifting and, ultimately, the cargo collapsing.

本考案に於ては係合用突部として下蓋構成部材
としての支え片６，６をうまく利用し得るような
構成にしたので、係合用突部の形成を省略でき、
その分この種係合式包装箱の構造ひいては組立て
作業を簡易化でき、更に係合が広い面積範囲に亘
つて行なわれるので、係合用突部としての支え片
６，６が折損して機能を低下するような危険性が
なく、安定確実な荷崩れ防止効果が得られ、高品
質の製品を安価に提供できる。 In the present invention, since the structure is such that the supporting pieces 6, 6 as the lower lid constituent members can be effectively used as the engaging protrusions, the formation of the engaging protrusions can be omitted.
Therefore, the structure and assembly work of this type of engaging packaging box can be simplified, and since the engagement is performed over a wide area, the support pieces 6, 6, which serve as engagement protrusions, can break and deteriorate in function. This eliminates the risk of cargo collapse, provides a stable and reliable effect of preventing cargo collapse, and enables the provision of high-quality products at low prices.
