Description

この発明は、粉体や液体が充填された袋を箱詰めして輸送・保管する際、箱に内挿されて強度を高める包装用胴枠に関するものである。   BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging body frame that is inserted into a box to increase strength when a bag filled with powder or liquid is packed and transported / stored.

例えば、図5に示すように、小麦粉等の粉体や洗剤等の液体が充填された袋Sを輸送・保管する際には、箱Bに補強用の胴枠51を内装することがある。この胴枠51は、段ボール製のシート材から成り、外周各面をなす側板52を、鉛直方向の罫線53を介して連設し、側板52を罫線53に沿って周方向に折り曲げ、角環状としたものである。 For example, as shown in FIG. 5 , when a bag S filled with a powder such as wheat flour or a liquid such as a detergent is transported and stored, a reinforcing body frame 51 may be provided in the box B. The body frame 51 is made of a corrugated cardboard sheet, and side plates 52 that form outer peripheral surfaces are connected to each other via a ruled line 53 in the vertical direction, and the side plate 52 is bent in the circumferential direction along the ruled line 53 to form a rectangular ring. It is what.

ところで、袋Sに詰められた粉体や液体は、下方へ崩れるように広がろうとするため、胴枠51及び箱Bの下部が大きな内圧を受けて、長時間の輸送や保管に伴い、外側へ膨らむ胴膨れ現象を生じることがある。   By the way, since the powder and liquid packed in the bag S tend to spread so as to collapse downward, the lower part of the trunk frame 51 and the box B is subjected to a large internal pressure, and the outer side is associated with long-time transportation and storage. It may cause a swelling phenomenon.

その対策として、下記特許文献1には、図6に示すように、箱Bに内装する胴枠61として、外周各面をなす逆台形状の側板62を罫線63を介して連設し、側板62を罫線63に沿って周方向に折り曲げ、下窄まりのテーパ状とすることにより、袋Sからの内圧による胴膨れを防止しようとするものが記載されている。 As a countermeasure, as shown in FIG. 6 , as shown in FIG. 6 , as shown in FIG. 6 , an inverted trapezoidal side plate 62 having outer peripheral surfaces is continuously provided as a body frame 61 provided in the box B via a ruled line 63. There is described a technique in which 62 is bent in a circumferential direction along a ruled line 63 to have a tapered shape with a constriction, thereby preventing a swelling of the body due to internal pressure from the bag S.

しかしながら、上記のように、下窄まりのテーパ状とした胴枠では、箱のサイズに比較して、胴枠内の有効容量がかなり減少し、輸送時や保管時におけるスペース効率が低下するという問題がある。   However, as described above, in the case frame having a tapered shape, the effective capacity in the case frame is considerably reduced compared to the size of the box, and the space efficiency during transportation and storage is reduced. There's a problem.

そこで、この発明は、袋を収納する内部の有効容量を確保しつつ、胴膨れを防止できるようにすることを課題とする。   In view of the above, an object of the present invention is to prevent the swelling of the body while ensuring the effective capacity inside the bag.

上記課題を解決するため、この発明は、外周各面をなす側板を、罫線を介して連設し、側板を罫線に沿って周方向に折り曲げ、角環状として箱に内装する胴枠において、側板が隣り合う少なくとも一つの角部に、鉛直な罫線から下方及び上方の端縁へ向けて二股状に分岐する斜め方向の罫線を入れ、この罫線に挟まれた三角状部を形成したのである。 In order to solve the above-mentioned problems, the present invention provides a side plate in which a side plate forming each outer peripheral surface is connected via a ruled line, the side plate is bent in a circumferential direction along the ruled line, and is mounted in a box as a rectangular ring. An oblique ruled line bifurcated from the vertical ruled line toward the lower and upper edges is put in at least one corner adjacent to each other to form a triangular part sandwiched between the ruled lines.

この発明に係る包装用胴枠では、粉体や液体を充填した袋を挿入して、大きな内圧が作用すると、三角状部が外側へ押されて、側板に張力が作用し、これに伴い、側板に膨らみに抗する復元力が生じるので、胴枠及び箱の胴膨れが防止される。   In the packaging body frame according to the present invention, when a bag filled with powder or liquid is inserted and a large internal pressure is applied, the triangular part is pushed to the outside, and tension is applied to the side plate. Since a restoring force against the swelling is generated on the side plate, the trunk of the trunk frame and the box is prevented.

まず、この発明の第1実施形態を図1及び図2に基づいて説明する。   First, a first embodiment of the present invention will be described with reference to FIGS.

この胴枠1は、図1に示すような段ボール製シート材から成る帯状のブランクを組み立てて形成され、図2に示すように、小麦粉等の粉体が充填された袋Sを輸送・保管する際に、箱Bに内装される。   The body frame 1 is formed by assembling a strip-shaped blank made of a corrugated cardboard sheet material as shown in FIG. 1, and transports and stores a bag S filled with powder such as flour as shown in FIG. In the meantime, it is installed in the box B.

図1に示すブランクでは、外周4方向の各面をなす側板2が鉛直な罫線3を介して連設されると共に、一端の側板2の外側縁に罫線3を介して継代片4が連設されている。側板2が隣り合う三つの稜部には、罫線3から下方及び上方の端縁へ向けて二股状に分岐する斜め方向の罫線5が入れられ、この罫線5に挟まれた三角状部6が形成されている。   In the blank shown in FIG. 1, the side plate 2 forming each surface in the four directions of the outer periphery is connected through a vertical ruled line 3, and the passage piece 4 is connected to the outer edge of the side plate 2 at one end through the ruled line 3. It is installed. The three ridges adjacent to the side plate 2 are provided with diagonal ruled lines 5 that bifurcate from the ruled line 3 toward the lower and upper edges, and a triangular part 6 sandwiched between the ruled lines 5 is formed. Is formed.

このようなブランクから図2に示すように胴枠1を組み立てるには、側板2を罫線3に沿って周方向に折り曲げ、継代片4を反対側の側板2に貼り付けて、角環状に形成する。このとき、各稜部の上下角部の三角状部6は、罫線5に沿って内側に傾斜する。   In order to assemble the body frame 1 from such a blank as shown in FIG. 2, the side plate 2 is folded in the circumferential direction along the ruled line 3, and the passage piece 4 is attached to the side plate 2 on the opposite side to form an angular ring shape. Form. At this time, the triangular portion 6 at the upper and lower corners of each ridge portion is inclined inward along the ruled line 5.

上記のような胴枠1では、箱Bに内装し、袋Sを挿入した状態において、袋Sが下方へ崩れるように広がろうとして、下部に大きな内圧が作用すると、下方の三角状部6が外側へ押されて、側板2の下部に張力が作用し、これに伴い、側板2の下部に膨らみに抗する復元力が生じるので、胴枠1及び箱Bの下部における胴膨れが防止される。   In the case frame 1 as described above, when the bag S tries to spread so as to collapse downward while the bag S is inserted in the box B and a large internal pressure acts on the lower part, the lower triangular part 6 Is pushed outward, tension is applied to the lower part of the side plate 2, and a restoring force against the swelling is generated in the lower part of the side plate 2, so that the upper part of the body frame 1 and the lower part of the box B is prevented from being swollen. The

また、胴枠1の上部にも、下部より小さい内圧が作用するが、上方の三角状部6も外側へ押されるので、側板2の上部にも張力が作用し、側板2の上部に膨らみに抗する復元力が生じて、胴枠1及び箱Bの上部における胴膨れも防止される。   In addition, an inner pressure smaller than the lower portion acts on the upper portion of the body frame 1, but the upper triangular portion 6 is pushed outward, so that a tension acts on the upper portion of the side plate 2, and the upper portion of the side plate 2 swells. A resisting restoring force is generated, and the body frame 1 and the upper part of the box B are prevented from being swollen.

次に、この発明の第2実施形態を図3及び図4に基づいて説明する。 Next, a description will be given of a second embodiment of the present invention in FIGS.

この胴枠1は、図3に示すブランクを、図4に示す形態に組み立てて使用するものであり、上記第1実施形態のものに比較して、継代片4を上下方向の中間部分のみとし、継代片4の下方及び上方に対応して設けた三角状部6の先端縁を、反対側の側板2に内接させることを特徴としている。 This trunk frame 1 is used by assembling the blank shown in FIG. 3 into the form shown in FIG. 4 , and the passage piece 4 is only in the middle part in the vertical direction as compared with the one in the first embodiment. The tip edge of the triangular portion 6 provided corresponding to the lower side and the upper side of the passage piece 4 is inscribed in the side plate 2 on the opposite side.

このような胴枠1では、周方向にバランスよく胴膨れを防止することができ、包装状態での変形を極力防止できる。   In such a trunk frame 1, swelling of the trunk can be prevented with a good balance in the circumferential direction, and deformation in the packaged state can be prevented as much as possible.

なお、上記各実施形態では、罫線5を傾斜角が一定の直線としたが、罫線5は、傾斜角度が途中で変化する折線としてもよく、湾曲したものとしてもよい。   In each of the above embodiments, the ruled line 5 is a straight line having a constant inclination angle. However, the ruled line 5 may be a broken line whose inclination angle changes midway or may be curved.
