Description

前記ブランクは少なくとも１組のフラップ素材を有し、該フラップ素材は、前記内側パネルから遠位縁部まで延びる、相対する中間フラップを有する。前記フラップ素材のパネルとの交差部から遠位縁部までの前記フラップ素材の平均の横方向長さの合計は、第１のフラップ素材の前記交差部から第２のフラップ素材の前記交差部までの前記パネルの横方向長さと等しい又はこれより短い。各フラップ素材又は中間フラップは、好ましくは、複数のフラップ部分を有し、各フラップ部分は、これに隣接するフラップ部分と連続しており、又は前記隣接するフラップ部分から分離しており、各組のフラップ部分は、組み立てられたときに前記容器の１つの側壁を構成する。
The blank has at least one set of flap materials that have opposing intermediate flaps that extend from the inner panel to a distal edge . The sum of the average lateral lengths of the flap material from the intersection with the panel of flap material to the distal edge is from the intersection of the first flap material to the intersection of the second flap material. Equal to or shorter than the lateral length of the panel. Each flap material or intermediate flap preferably has a plurality of flap portions, each flap portion being continuous with or separated from the adjacent flap portions, The flap portion of the container constitutes one side wall of the container when assembled.

前記したように、本発明に実施例において、前記フラップ素材の平均の横方向幅の合計は、前記フラップ素材が延びるパネルの横方向幅と等しい又はこれより狭い。この関係は、容器製造時に、少なくとも１組の相対するフラップが巻かれることを許し、これにより、各フラップの遠位縁部が、互いに近付けられ、前記フラップが延びる、関連するパネルに近付けられる。三層構造の実施例において、前記フラップ素材は内側パネル又は中間パネルのいずれか一方のパネルを構成してもよく、前記フラップ素材が延びるパネルは他方のパネルを構成してもよい。巻かれた構造は、前記容器素材が前記容器へと組み立てられたときに側壁として機能する。前記フラップの遠位縁部の形状が変わると、横方向長さの値が変化することは、当業者には明らかである。このため、合計の長さが「平均」という用語を用いて記載されているが、前記フラップが巻かれ、互いに近付けられたときに重なり状態を生じさせない形状を含むことは、本発明の範囲内である。
As described above, in the embodiment of the present invention, the total of the average lateral width of the flap material is equal to or smaller than the lateral width of the panel in which the flap material extends. This relationship allows at least one set of opposing flaps to be rolled during container manufacture so that the distal edges of each flap are brought closer together and the associated panel from which the flaps extend. In the embodiment of the three-layer structure, the flap material may constitute one of an inner panel and an intermediate panel, and the panel from which the flap material extends may constitute the other panel. The wound structure functions as a side wall when the container material is assembled into the container. It will be apparent to those skilled in the art that the lateral length value changes as the shape of the distal edge of the flap changes. For this reason, although the total length is described using the term “average”, it is within the scope of the present invention to include shapes that do not cause overlapping when the flaps are wound and brought close together. It is.

各中間フラップ部分の遠位端部は、図４に示したように、山形の縁部５３ａ／ｂ、５５ａ／ｂ、５７ａ／ｂ、５９ａ／ｂにより特徴付けられている。このような山形の縁部又は非直線状の縁部は、後述するように、容器２０の組立て及び使用の後に生じることがある破裂及び圧縮応力を効果的に防ぐ。このため、曲線状の縁部又は繰り返しの四角形若しくは鋸歯形状の縁部が望ましいと考えられる。しかし、本発明の実施例の操作又は構成がそのような非直線状の縁部を含むことは必須はなく、直線状の縁部は、本明細書において説明した利益を与える。
The distal end of each intermediate flap portion is characterized by chevron edges 53a / b, 55a / b, 57a / b, 59a / b, as shown in FIG. Such chevron edges or non-linear edges effectively prevent rupture and compressive stresses that may occur after assembly and use of container 20, as will be described below. For this reason, curved edges or repetitive square or serrated edges are considered desirable. However, it is not essential that the operation or configuration of embodiments of the present invention include such non-linear edges, which provide the benefits described herein.

早期の折り曲げ解除を防ぐため、材料の一部によるフラップ７２〜７８の連結を保つことが望ましい（これは、前記フラップの遠位端部におけるパネル間の不完全なスリッティングにより生じさせることができる。）。このため、解体された容器が消費者に届けられるとき、フラップ７２〜７８は、分離され、所定の位置に折り曲げられる。
It is desirable to keep the flaps 72-78 connected by a piece of material to prevent premature unfolding (this can be caused by incomplete slitting between panels at the distal end of the flap). .) For this reason, when the dismantled container is delivered to the consumer, the flaps 72-78 are separated and folded into place.
